Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an elevator shaft lifting construction platform. Background Technology

[0002] During building construction, operations such as masonry, plastering, and wiring are required inside elevator shafts. Since elevator shafts are narrow, vertical spaces, construction platforms need to be built to facilitate the operation of construction workers. For buildings with fewer floors, scaffolding can be erected layer by layer and then dismantled after construction is completed. However, for buildings with more floors, this method of erecting scaffolding layer by layer will consume a large number of scaffolds, and the workload of erection and dismantling is large, affecting the construction progress. Existing technologies typically use lifting-type elevator shaft operating platforms.

[0003] Existing elevator shaft construction platforms, such as the elevator shaft frame construction platform disclosed in announcement number CN220978760U, have a triangular diagonal brace. The lower end of the triangular diagonal brace is attached to the edge of the floor slab at the elevator shaft. In practical applications, it has been found that in order to lift the entire construction platform, it is necessary to tilt the construction platform to move the lower end of the triangular diagonal brace into the elevator shaft, thereby avoiding the right angle bracket from obstructing the lifting of the construction platform by the edge of the elevator shaft. Under such operation, all non-fixed work tools inside the construction platform need to be moved during the lifting process to prevent them from slipping during tilting. After the construction platform is lifted, the work tools also need to be transferred back to the construction platform, which increases the inconvenience of use. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an elevator shaft lifting construction platform.

[0005] The technical solution is as follows: A lifting construction platform for elevator shafts includes a support plate 1 and a support structure. The support structure includes a support plate 2. Vertical rods and diagonal rods are fixedly connected to both sides of the bottom of the support plate 2. The bottom end of the diagonal rod is fixedly connected to the lower part of the vertical rod on the same side. Hook rods are fixedly connected to the lower part of the vertical rod away from the diagonal rod. The bottom of the support plate 1 is U-shaped, and the two sides of the support plate 2 are slidably connected to the bottom two sides of the support plate 1 respectively. Lifting rings are fixedly connected to the four corners of the top of the support plate 1.

[0006] Preferably, the first support plate has a groove, and a liftable insert rod is installed in the groove. The insert rod can slide along the length of the groove. The second support plate has a corresponding insertion hole for the insert rod.

[0007] Preferably, a protective frame is fixedly connected to the support plate. The protective frame is located around the slide groove. A telescopic drive component that can be raised and lowered is installed inside the protective frame. The output end of the telescopic drive component is fixedly connected to the plug rod, and the fixed end of the telescopic drive component is slidably connected to the protective frame.

[0008] Preferably, the protective frame is threaded with a screw, one end of which is rotatably connected to the fixed end of the telescopic drive component.

[0009] Preferably, both support plate one and support plate two have multiple through holes for bolt connection. Support plate one has two sets of through holes, which correspond to the through holes on support plate two, so as to fix support plate two at different positions on support plate one.

[0010] Preferably, multiple connecting rods are fixed between the two diagonal rods and between the two vertical rods.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: The elevator shaft lifting construction platform of this utility model eliminates the need to tilt the entire construction platform to move it into the right-angle bracket, as is required in existing technologies. This avoids the need to move and relocate non-fixed work tools within the construction platform during the lifting process. By driving the insertion rod with a telescopic drive component, the support structure slides within the support plate, achieving the separation and re-support of the hook rod from the lower edge of the elevator shaft opening. This simplifies the lifting operation process, reduces the labor intensity and operation time of workers, and improves construction efficiency. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0018] The embodiment provides an elevator shaft lifting construction platform, such as Figures 1-4 As shown, it includes a support plate 1 and a support structure 2. The support structure 2 includes a support plate 21. Vertical rods 22 and diagonal rods 23 are fixed to both sides of the bottom of the support plate 21. The bottom end of the diagonal rod 23 is fixed to the lower part of the vertical rod 22 on the same side. Hook rods 24 are fixed to the lower part of the vertical rod 22 away from the diagonal rod 23. The bottom of the support plate 1 is U-shaped, and the two sides of the support plate 21 are slidably connected to the two sides of the bottom of the support plate 1. The two sides of the bottom of the support plate 1 can maintain an effective connection while providing a sliding path for the support plate 21, so as to ensure that the support structure 2 can be lifted together with the support plate 1. Lifting rings 3 are fixed to the four corners of the top of the support plate 1.

[0019] The support plate 1 has a groove 101, and a liftable insert rod 8 is provided in the groove 101. The insert rod 8 can slide along the length of the groove 101. The support plate 21 has a hole 211 corresponding to the insert rod 8. When the insert rod 8 is inserted into the hole 211, the sliding of the insert rod 8 along the length of the groove 101 can drive the support plate 21 to slide relative to the support plate 1.

[0020] A protective frame 9 is fixedly connected to the support plate 1. The protective frame 9 is located around the slide groove 101. A telescopic drive component 10 that can be raised and lowered is provided inside the protective frame 9. The output end of the telescopic drive component 10 is fixedly connected to the insertion rod 8, and the fixed end of the telescopic drive component 10 is slidably connected to the protective frame 9. The insertion rod 8 is driven to reciprocate along the length direction of the slide groove 101 by extending or shortening the telescopic end of the telescopic drive component 10.

[0021] The protective frame 9 is threaded with a screw 11. One end of the screw 11 is rotatably connected to the fixed end of the telescopic drive component 10. By rotating the screw 11, the telescopic drive component 10 is driven to move up and down relative to the protective frame 9.

[0022] Both support plate 1 and support plate 21 have multiple through holes 13 for bolt connection. There are two sets of through holes 13 on support plate 1. The two sets of through holes 13 on support plate 1 correspond to the through holes 13 on support plate 21 to fix support plate 21 at different positions on support plate 1.

[0023] Multiple connecting rods 12 are fixed between the two diagonal rods 23 and between the two vertical rods 22. The connecting rods 12 are used to improve the structural stability. The connecting rods 12 between the two vertical rods 22 can also prevent people from passing through to avoid accidents.

[0024] Working process: Initially, the bottom end of the insert rod 8 does not extend to the bottom of the slide groove 101, and the telescopic drive component 10 is in a retracted state. When in use, the support structure 2 is placed in the elevator shaft. The support structure 2 is supported by the hook rod 24 on the lower edge of the elevator shaft. At this time, the top of the support plate 21 is at the upper edge of the elevator shaft. Then, the two sides of the support plate 2 are aligned with the bottom sides of the support plate 1, and the support plate 1 is slid from the upper edge of the elevator shaft into the shaft until the first set of through holes 13 of the support plate 1 is aligned with the through holes 13 of the support plate 21. At this time, the insert rod 8 is directly above the insert hole 211 of the support plate 21. Then, the support plate 1 and the through holes 13 aligned with the support plate 21 are fixed with bolts to complete the construction platform construction of the current elevator shaft floor. After that, the workers can carry out construction work on the support plate 11.

[0025] When the construction platform needs to be lifted to the next higher floor for construction work, the cable of the lifting device at the top of the elevator shaft is connected to the lifting ring 3 of support plate 1. Then, by rotating the screw 11, the telescopic drive 10 moves downward on the protective frame 9 until the bottom end of the insert rod 8 moves into the insertion hole 211 of support plate 21. The bolt connection between the through holes 13 aligned with support plate 11 and support plate 21 is then released. Subsequently, the telescopic drive 10 drives the insert rod 8 to move away from the shaft opening in the slide 101, causing support plate 21 to move away from the shaft opening within support plate 11. Thus, the entire support structure 2 moves away from the shaft opening until the hook rod 24 of support structure 2 is no longer supported on the lower edge of the elevator shaft. At the same time, the second set of through holes 13 of support plate 11 is aligned with the through holes 13 of support plate 21. Then, the bolts are used to connect support plate 11 and support plate 21. The currently aligned perforations 13 are fixed to ensure the stability of the subsequent support plate 1 and the entire support structure 2 during the lifting process. Then, the support plate 1 and the entire support structure 2 are lifted upwards by the lifting device until the support plate 1 reaches the next higher floor of the shaft. Then, the bolt connection between the support plate 1 and the currently aligned perforations 13 of the support plate 21 is released. Then, the telescopic drive 10 drives the insertion rod 8 to move in the reverse direction and reset in the slide groove 101, so that the insertion rod 8 drives the entire support structure 2 to move closer to the elevator shaft until the hook rod 24 of the support structure 2 is supported on the lower edge of the elevator shaft where the current support plate 1 is located. At this time, the first set of perforations 13 of the support plate 1 is re-aligned with the perforations 13 of the support plate 21. Then, the currently aligned perforations 13 of the support plate 1 and the support plate 21 are fixed together by bolts, completing the construction platform construction of the current elevator shaft floor.
