[0002] The integral lifting operation platform for a shaft is a platform used for operation construction such as an elevator shaft. In the prior art, since the elevator shaft is in an unenclosed state, the lifting operation platform is easily impacted by falling objects from above. The existing solution is to build a protective plate at the wellhead on the top of the elevator shaft to avoid falling objects, but the falling objects at the floor openings between the wellhead and the lifting operation platform cannot be prevented. And directly setting a fixed protective plate on the lifting operation platform will interfere with the lifting operation of the traction system such as a tower crane for the lifting operation platform. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an integral lifting operation platform for a shaft that can block falling objects, ensure operation safety, and at the same time will not interfere with the lifting operation of the traction system.

The protection structure is arranged on the platform body. The protection structure includes a first protection net, and the first protection net is parallel to the platform body and is arranged on the platform body in a liftable manner. The first protection net can be rotated towards the side of the platform body to be perpendicular to the platform body.

[0005] Further, the platform body is in an L shape and includes a horizontal plate, a vertical plate and a reinforcing rod. The vertical plate includes two vertical rods perpendicularly connected to the horizontal plate and a second protection net between the vertical rods; an inclined reinforcing rod is connected between the horizontal plate and the vertical rods.

[0006] Further, the protection structure includes a lifting rod. The vertical rod is hollow, and the lifting rod is movably arranged in the vertical rod; the first protection net is rotatably arranged on the lifting rod.

[0007] Further, the protection structure further includes a first bolt. The lifting rod is provided with a plurality of jacks at intervals along its length direction, and the bolts are arranged in parallel on the horizontal plate and pass through the corresponding jacks.

[0008] Further, corresponding lifting rods are arranged on the two vertical rods, and the first protection nets on the two lifting rods are detachably connected.

[0009] Furthermore, the protection structure further includes a second bolt. Connecting grooves and connecting protrusions are respectively provided on the adjacent edges of the two protection nets, and the connecting grooves are matched with the connecting protrusions. The connecting grooves and the connecting protrusions are provided with insertion holes in a direction perpendicular to the edge of the first protection net, and the second bolt passes through the two insertion holes respectively.

[0010] Furthermore, an L-shaped clamping plate is connected to the end of the vertical rod far from the horizontal plate, and the L-shaped clamping plate is used for clamping with the edge of the floor opening in the shaft.

[0011] Furthermore, the platform body further includes an insertion rod.

[0033] As described above, when the platform body is lifted to the specified height, the fixing plate 6 rotates and extends into the floor opening, and the insertion rod 7 is horizontally arranged at the floor opening and passes through the fixing plate 6, thereby further fixing the position of the platform body in the shaft.

[0034] Embodiment 1:

[0035] As Figure 1 and Figure 2 shown, the overall shaft lifting operation platform of this embodiment includes a platform body and a protection structure. The protection structure is provided on the platform body. The protection structure includes a first protective net 9. The first protective net 9 is parallel to the platform body and is liftably arranged on the platform body. The first protective net 9 can be rotated to be perpendicular to the platform body towards the side of the platform body.

[0036] The platform body is L-shaped and includes a horizontal plate 1, a vertical plate, and a reinforcing rod 4. The vertical plate includes two vertical rods 2 perpendicularly connected to the horizontal plate 1 and a second protective net 3 between the vertical rods 2. An inclined reinforcing rod 4 is connected between the horizontal plate 1 and the vertical rod 2.

[0037] The protective structure includes a lifting rod 8. The vertical rod 2 is hollow, and the lifting rod 8 is movably arranged inside the vertical rod 2. The first protective net 9 is rotatably arranged on the lifting rod 8.

[0038] The protective structure further includes a first bolt. The lifting rod 8 is provided with a plurality of jacks at intervals along its length direction. The bolts are arranged in parallel on the horizontal plate 1 and pass through the corresponding jacks.

[0039] Lifting rods 8 are correspondingly arranged on the two vertical rods 2, and the first protective nets 9 on the two lifting rods 8 are detachably connected.

[0040] The protective structure further includes a second bolt. Connecting grooves 10 and connecting protrusions 11 are respectively provided on the adjacent edges of the two protective nets. The connecting groove 10 is matched with the connecting protrusion 11. The connecting groove 10 and the connecting protrusion 11 are provided with jacks in a direction perpendicular to the edge of the first protective net 9. The second bolts respectively pass through the two jacks.

[0041] An L-shaped clamping plate 5 is connected to the end of the vertical rod 2 far from the horizontal plate 1. The L-shaped clamping plate 5 is used for clamping with the edge of the floor opening in the hoistway.

[0042] The platform body further includes a plug rod 7. One end of the vertical rod 2 far from the horizontal plate 1 is rotatably connected to a fixing plate 6. The fixing plate 6 is provided with a jack. The plug rod 7 is horizontally arranged at the floor opening in the hoistway and both ends of the plug rod 7 protrude from both sides of the floor opening edge. The plug rod 7 is inserted into the jack.

[0043] Working principle: When the tower crane hoists and lowers the platform main body, the protective structure on the lifted platform main body is in a retracted state. Among them, the cooperation between the two first protective nets 9 is released, and the first protective net 9 rotates to be parallel to the side surface of the platform main body. Then, the lifting rod 8 slides into the vertical rod 2 under the platform main body, and the first protective net 9 also slides down and abuts against the upper plane of the lifted platform main body. At this time, the arrangement of the ropes of the tower crane is not interfered, and normal operation can be carried out.

[0044] When the tower crane lifts the main body of the platform to the height of the working shaft, it is fixed by clamping the L-shaped clamping plate 5, fixing plate 6, inserting rod 7, etc. under the main body of the platform with the edge of the floor opening; then the lifting rod 8 is pulled up to a suitable height and fixed by inserting a pin. Then the first protective net 9 is rotated to a state parallel to the horizontal plate 1 of the main body of the platform. At this time, the connecting grooves 10 of the two first protective nets 9 cooperate with the connecting protrusions 11, and their jacks are opposite; at this time, the pin is pushed into the jack, and the two first protective nets 9 can be fixed to protect the upper side of the main body of the platform and ensure the safe operation of workers.

[0045] In summary, for the overall lifting operation platform of the shaft provided by the present utility model, through the lifting design of the first protective net on the platform body, the height can be increased during use to prevent falling objects from above; combined with the design that the first protective net can rotate towards the side of the platform body, when lifting and towing are required, the first protective net can be lowered and rotated towards the side of the platform body so that it is parallel to the side of the platform body. In this way, the space above the platform body is no longer interfered by the first protective net, and the towing rope of the tower crane can be conveniently hung on the platform body for lifting operations.
