With the constant construction of modern cities, elevators are used more and more frequently. Now that the elevator has become an indispensable tool for high-rise buildings and shopping malls, it is necessary for the installation to formulate a construction plan. How much is it to install the elevator? Let's take a look at the elevator installation construction plan and how much money to install the elevator .
Elevator installation construction plan
First, the installation program:
1, pre-installation preparation and precautions:
1 suffering from heart disease, high blood pressure, epilepsy may not work on high ground.
Twenty-six people were installed in the installation team. They were installed by professionals and they held certificates.
3Before installation, you must be familiar with all the safety requirements during the installation phase to understand the principle and structure of the mechanical and electrical performance of the elevator.
4 ready to install all the tools, security appliances, spare parts and so on.
5 The spigots, pin holes, screw holes, etc. of the components, such as the standard section, wall bracket, and counterweight system, must be rusted, deburred, and placed on these parts and on the rack and counterweight guides. Apply a proper amount of grease to ensure that the rolling elements are fully lubricated and flexible.
6 Install protection sheds and fences around the installation site and set up guard guards and warning signs.
7 The base must meet the specified solidification cycle and strength.
Second, the installation steps:
1 First transport the base frame of the guide frame and the enclosing base frame to the pre-prepared foundation. Connect and fasten with the anchor bolts. Install the first, second, and third section standard sections. After the standard section is connected to the chassis, check the verticality of the guide frame and the horizontal direction with a theodolite or plumb line in both directions. The error is less than 1/1000M.
2 Install the basic chassis around the four columns and door frames, connect them to the chassis with bolts, and adjust the vertical and flexibility of the door frame.
3 Install the cage and adjust the pressure roller on the rotating mechanism to the maximum eccentric position. Remove the safety hook on the cage and the roller that affects the safety and loosen the brake on the motor in the cage. Use a tower crane to lift the cage, lift the cage from the guide frame into the guide frame, place it on a suitable height of the mat, and reinstall the safety hook and roller. The distance between the column tubes is 0.5mm. The gap at the back of the rack is 0.55mm, and the meshing gap between the transmission gear and the rack is 0.2 to 0.3mm. At the same time, ensure that the center plane of the anti-fall safety gear and the transmission wheel in the width direction is in the middle of the thickness of the rack. In addition to resetting the brake by the wedge, insert the crowbar into the hole of the coupling and manually open the brake for each stroke. Lift the cage by 1m or so, remove the cage under the cage, install the buffer spring, and then slowly lower the cage to the buffer spring. Check the transmission gear and rack clearance at 0.2-0.3mm while manually moving up and down.
4 Install the safety cage at the top of the cage.
5 Use a tower crane to lift the counterweight from the square of the pylon, guide the guide wheel into the guide rail, and smoothly stop on the bolster.
6 After the guide frame is raised to 10.5 meters, the first wall frame should be set at 9 meters from the ground, and the vertical deviation between the entire guide frame and the level measured by the theodolite once again should be 5 mm.
7 The installation of electrical equipment and control system shall be conducted by a full-time professional electrician. The wiring of each safety control switch shall be correct. The phase sequence of the power supply must ensure that the direction of the up and down of the cage is the same as that of the joystick. Check the safety control switches, including fence gate limit switches, cage single, double door limit switches, cage top door limit switches, including the cage, the lower limit and the three-phase limit switch, broken rope protection switch is normal, Sensitive and reliable action. Correctly install and adjust the limit baffle and baffle at the bottom of the guide, so that the movement is correct. The grounding resistance shall be measured with a grounding resistance tester and shall not be greater than 4 ohms. The insulation resistance to earth of motors and electrical components measured with a 500V megohmmeter shall be not less than 0.5 MΩ. All aspects are met after the power is turned on, and the driver is cautiously manipulating the handle. The height of the journey shall not exceed 5 meters, the cage shall run smoothly, no abnormal sound, the brake shall be in normal operation, and the roller and gear mesh shall meet the above regulations. After the no-load test is normal, the load test shall be carried out again. As the upper limit baffle has not been installed at this time, Stopper, so must be careful when testing, and the top of the cage must be monitored and directed to prevent the cage from falling.
8 After the height of the guide frame is installed and the test run is normal, the height of the guide frame shall be further installed. The height of the height-increasing installation shall be determined according to the needs of the project construction. At the same time, the wall hangers and the cable guides for the aisle masts and bridge links are installed accordingly. Finally, the head frame and the pulley are installed, and the wire rope is installed. The two ends of the wire rope and the eccentric rope and the counterweight of the cage top are each tightened with three ropes, and the tightening degree is 1/3. The limit baffle is installed so that the position is correct and the action is sensitive and reliable.
9 The free height of the construction elevator is 9M. Attach a wall frame to each main floor of the main body. Attach the embedded part of the wall frame on each floor. Attach the wall shelf to the two floors of the temporary operation floor.
10 Drop test: After the entire frame installation process is completed, a fall arrest test is also required. When carrying out the fall arrest test, no one is allowed inside the cage. Make sure the brake is working properly. After the fall arrest test meets the requirements, the fall arrester should be reset
How much money to install the elevator
The price depends on what kind of ladder you use. In general, if it is a residential building, after the installation can use a sightseeing ladder, that is, three kinds of transparent kind. A sightseeing ladder is generally slightly more expensive than an ordinary ladder, but not much more expensive. , 800kg, 1.5m/s, standard. The equipment price is about 135,000, including installation and other expenses, about 180,000.
The main considerations for retrofitting are: civil construction and elevator equipment:
1, civil engineering package expansion materials, labor, may also apply for approval of the Ministry of Housing, about 10W or so.
2. The elevators mainly include purchase, installation, and approval. The low-grade domestic ladders of 130,000 yuan can be used. The floors are not high and need not be too good. The latter can be a good point for the maintenance company.
