[0002] In the construction of high-rise buildings, the elevator shaft usually adopts a triangular support unloading platform to set up the platform and close the shaft. This method increases the material cost, makes it inconvenient for workers to hoist, and has high installation risks, which may cause concrete slag to fall in the elevator shaft, causing serious consequences and losses. Utility Model Content

[0003] In view of the technical problems in the prior art, the utility model provides an elevator shaft operating platform, including a platform bottom plate and a supporting mechanism, the platform bottom plate is provided with a lifting ring for connecting with a lifting mechanism, the platform bottom plate is fixedly installed on the supporting mechanism, the supporting mechanism moves up along the inner wall of the elevator shaft under the drive of the lifting mechanism, and is relatively fixed to the elevator shaft through a reserved hole arranged on the inner wall, the supporting mechanism includes a supporting frame, a plurality of supporting rods, a plurality of return springs and a plurality of supporting legs, the supporting rods, the return springs and the supporting legs correspond to each other one by one, the plurality of supporting rods are symmetrically arranged at both ends of the supporting frame, and the middle part or the vicinity of the middle part of the supporting rod is rotatably connected with the supporting frame through a pin shaft, one end of the supporting rod extends out of the supporting frame and abuts against the inner wall, and the other end is connected with the supporting frame through a return spring, the supporting leg is fixedly installed on the supporting frame and is located above the side of the pin shaft close to the inner wall, and when the supporting rod extends into the reserved hole, the top surface of the supporting rod abuts against the bottom surface of the supporting leg under the elastic force of the return spring.

[0004] Furthermore, the support mechanism also includes a plurality of rollers, the rollers corresponding to the support rods one by one, and the rollers are rotatably mounted on one end of the support rod extending out of the support frame.

[0005] Furthermore, the roller is made of rubber.

[0010] Beneficial effects:

[0011] 1. In the utility model, by providing a support frame, a plurality of support rods, a plurality of return springs and a plurality of legs, it is not necessary to erect a plurality of frames from bottom to top, which can reduce the waste of materials, labor and time caused by erecting scaffolds in the elevator shaft, save costs, and at the same time can conveniently and quickly realize the movement of the operating platform with high safety. Specifically, when the platform bottom plate and the support frame are moved up by the lifting mechanism, the support rod rotates around the pin axis point under the restriction of the inner wall of the elevator shaft and folds, and detaches from the reserved hole. At this time, the return spring is in a stretched state. When the operating platform moves to another reserved hole, the return spring restores its original length, and the support rod rotates around the pin axis under the action of elastic force and slides into the reserved hole. Since the support rod is blocked by the legs and cannot be folded, the operating platform will not move downward relative to the elevator shaft.

[0012] 2. In the utility model, by setting the roller, the friction resistance between the support rod and the inner wall can be reduced, which facilitates the movement of the support frame and the platform bottom plate; combined with the setting of the roller made of rubber material, on the one hand, it can provide buffering to avoid jamming during the upward movement and increase the service life of the roller; on the other hand, it can increase the friction resistance when cooperating with the reserved hole to avoid sliding between the connecting rod and the reserved hole.

[0013] 3. In the present invention, the stability of the platform bottom plate can be increased by setting four support rods; combined with the setting that the spacing between the support rods is not less than 1200mm and not more than 2000mm, the structural strength of the operating platform can be improved and the safety can be further improved.

[0014] 4. In the present invention, when the support rod cooperates with the reserved hole, the bottom surface of the support rod is in a horizontal state, which can maximize the contact area between the support rod and the reserved hole, further improving the structural strength and stability of the operating platform; through the setting of the inner chamfer, the support rod can be easily separated from the reserved hole.

The multiple support rods 5 are symmetrically arranged at both ends of the support frame 4, and the middle part or near the middle part of the support rod 5 is rotatably connected to the support frame 4 through a pin shaft. One end of the support rod 5 extends out of the support frame 4 and abuts against the inner wall, and the other end is connected to the support frame 4 through a return spring 6. The support leg 7 is fixedly mounted on the support frame 4 and is located above the side of the pin close to the inner wall. When the support rod 5 extends into the reserved hole 3, the top surface of the support rod 5 abuts against the bottom surface of the support leg 7 under the elastic force of the return spring 6.

Specifically, when the platform bottom plate 1 and the support frame 4 are moved up by the lifting mechanism, the support rod 5 rotates around the pin axis point under the restriction of the inner wall of the elevator shaft and folds, and disengages from the reserved hole 3. At this time, the return spring 6 is in a stretched state. When the operating platform moves to another reserved hole 3, the return spring 6 restores its original length, and the support rod 5 rotates around the pin axis under the action of elastic force and slides into this reserved hole 3. Since the support rod 5 is blocked by the legs 7 and cannot continue to rotate and fold, the operating platform will not move downward relative to the elevator shaft.

[0032] In the present invention, preferably, Figure 1 As shown, the support rods 5 include four, and the two support rods 5 at each end are arranged at intervals; the interval between the two support rods 5 at each end is not less than 1200 mm and not more than 2000 mm.

[0033] In this embodiment, by setting four support rods 5, the stability of the platform base plate 1 can be increased; combined with the setting that the spacing between the support rods 5 is not less than 1200mm and not more than 2000mm, the structural strength of the operating platform can be improved and the safety can be further improved.
