Description

Technical Field

[0001] The utility model relates to a lifting operation platform for elevator shaft construction. Background Art

[0002] With the increase in industrial and civil construction projects and the increasing height of buildings, the construction of the interior of the elevator shaft is becoming more and more difficult, and safety hazards are emerging one after another. In the past construction process, workers usually used a large number of steel pipes to build a full-height frame as a support and protection device, which has the following disadvantages: First, the erection of the full-height frame requires a lot of manpower and material resources, which not only has low construction efficiency, but also brings too much concentrated load to the structure itself; secondly, during the erection process, due to the small space of the elevator shaft, the construction difficulty and cost are further increased, causing delays in the construction period; finally, when the support is dismantled after the project is completed, each steel pipe dismantled must be transported out of the elevator shaft, which is not only a large workload, but also poses a major safety hazard. For this reason, the existing technology has developed work platforms for the construction of elevator shafts, such as Figure 5 The existing work platform has the following problems:

[0003] The work platform is an integrated structure with a fixed height, while the height of the elevator shafts of different buildings may vary. For some elevator shafts that are too high, if the construction frame is not high enough, the only solution is to build a scaffold on the construction frame, which increases the construction cost and reduces the construction efficiency.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0018] The embodiment of the utility model comprises a construction frame and a lifting platform.

[0019] The construction frame comprises a top plate 1, a pull rope hook 2, a cross bar 3, a tightening screw 4, a reinforcing diagonal bar 5, a vertical supporting bar 6, a stair tread 8 and an anti-slip block 9.

[0020] The top plate 1 is fixed on the top of the vertical support rod 6, and the material of the top plate 1 is steel. One end of the reinforcing diagonal rod 5 is fixed to the top plate 1, and the other end is fixed to the vertical support rod 6 to enhance firmness. The stair tread 8 is fixed to the vertical support rod 6, and the upper surface of the stair tread 8 is provided with anti-skid grooves, which can prevent workers from slipping when passing the stair tread 8. The front bottom of the vertical support rod 6 is fixedly connected with an anti-skid block 9, and the anti-skid block 9 can be used to clamp the entire construction frame on the elevator shaft opening to prevent the construction frame from slipping, thereby achieving a safety effect. A pull rope hook 2 is fixed to one side of the top of the top plate 1.

[0021] The cross bar 3 is slidably mounted on the side of the top plate 1 , and the tightening screws 4 are mounted on the top plate 1 . The cross bar 3 is fixed to the top plate 1 by tightening the screws 4 .

[0022] The lifting platform includes a supporting column 7 , a construction platform 10 , a cross rod 11 , a fixed column 12 and a fastening screw 13 .

[0023] The fixed column 12 is fixed to the top of the top plate 1. The support column 7 is plugged into the fixed column 12, and the fastening screw 13 is installed on the support column 7. The fixed column 12 is fixed to the support column 7 by the fastening screw 13, so that the support column 7 can remain stable.

[0024] The construction platform 10 is fixed on the top of the support column 7. The cross bar 11 is welded and fixed on the support column 7 to enhance the firmness.

[0025] The utility model is made of steel as a whole. The steel has high strength and stability, can bear a large load, and has a long service life.
