Description

Technical Field

[0001] This utility model belongs to the field of hoisting cage technology, specifically relating to a movable hoisting cage structure. Background Technology

[0002] In building construction, the transfer of pipes between floors is a common and crucial operation. As a key piece of equipment for vertical transportation and inter-floor transfer, the safety and stability of the hoist cage directly impact construction efficiency and operational safety. However, existing hoist cage structures have several technical shortcomings in practical applications for transferring long, heavy materials such as pipes: Most existing hoist cages are of general-purpose design and lack dedicated fixing and protection structures for pipeline transportation. When the hoist cage is lifted to the edge of the target floor by a tower crane, the cage is often only temporarily positioned on the floor slab with simple support, without effective fixing devices. In this case, the hoist cage is prone to swaying due to slight external disturbances (such as wind or the inertia of tower crane operation). Especially during pipeline loading and unloading, the shift in the center of gravity of the pipeline will further aggravate the swaying of the cage, which not only increases the risk of pipeline falling but may also cause the cage to collide with the edge of the floor slab, damaging the building structure or the cage itself. Meanwhile, the lateral stability of the existing hoist cage is also difficult to guarantee. Due to the lack of lateral fixing mechanism, the hoist cage is prone to lateral slippage at the edge of the floor. Especially when hoisting long pipes, the part of the pipe extending out of the hoist cage will generate a lateral moment, causing the hoist cage to tilt outward. In severe cases, it may cause the entire hoist cage to overturn, resulting in a major safety accident. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a movable cage structure that solves the problems of existing cages being prone to swaying and having poor lateral stability due to the lack of a dedicated fixing and protection structure for pipeline transportation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a movable cage structure, including a cage mesh, which is welded and encloses three sides of the cage frame. A detachable protective door is installed on the open side of the cage frame. A cage bottom plate and a connecting frame are fixed at the bottom of the cage frame. The connecting frame is arranged on both sides of the cage bottom plate, and one end of the connecting frame on the open side of the cage frame extends outward. Auxiliary lifting lugs and two sets of main lifting lugs are welded on both sides of the cage frame.

[0005] The beneficial effects of this utility model are as follows: the extended part of the lap frame can be placed on the floor slab and fixedly connected to the floor slab with the anchor bolts to prevent the cage from swaying up and down; the auxiliary lifting lug can be attached to one end of the wire rope to connect to the floor to prevent the cage from swaying left and right, thereby achieving efficient and safe pipe hoisting and unloading.

[0006] To avoid friction between the hoisting wire rope and the cage netting, which could affect safety; As a further improvement to the above technical solution: each group of main lifting lugs consists of two lugs arranged opposite each other, and a rope-threading groove is cut into the cage mesh on one side of the main lifting lug.

[0007] The beneficial effects of this improvement are: the wire rope suspended on the tower crane hook can pass through the rope threading slot and be tied to the main lifting lug, avoiding friction with the cage net and affecting the safety of the wire rope.

[0008] To ensure the stability of the connection between the hoist cage and the anchor bolts on the floor slab; As a further improvement to the above technical solution: one side of the extended portion of the lap frame is welded to a wing plate of the positioning plate, and the other side of the positioning plate is provided with a through hole for mounting bolts.

[0009] The beneficial effects of this improvement are: the positioning plate can be used to connect the anchor bolts, ensuring the stability of the connection between the cage and the floor slab.

[0010] To prevent the cage from sliding outwards; As a further improvement to the above technical solution: the auxiliary lifting lug is arranged adjacent to the detachable protective door.

[0011] The beneficial effect of this improvement is that by attaching one end of the hand chain hoist to the giant column of the floor structure and hooking the other end of the hand chain hoist to the auxiliary lifting lugs on both sides, the cage can be prevented from sliding outward.

[0012] To make adjusting the horizontal position of the hoist cage easier and less strenuous; As a further improvement to the above technical solution: handles are installed on the cage frames on both sides of the detachable protective door.

[0013] The beneficial effect of this improvement is that the operator can hold the handle to pull and adjust the horizontal position of the cage, ensuring that the cage is placed in the appropriate position.

[0014] For easy loading and unloading of pipes within the cage frame; As a further improvement to the above technical solution: the four corners of the detachable protective door are provided with through holes for sliding insertion lifting eye bolts, and the lifting eye bolts are threadedly connected to the cage frame.

[0015] The beneficial effects of this improvement are: the lifting eye bolts can stably connect the detachable protective door and the cage frame, and the detachable protective door can be easily separated from the cage frame after removal, thereby enabling the installation and removal of pipelines.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0019] Example 1: As Figure 1As shown in Figure 3: A movable cage structure includes a cage mesh 2, which is welded and surrounds three sides of a cage frame 1. A detachable protective door 4 is installed on the open side of the cage frame 1. A cage bottom plate 9 and an overlapping frame 3 are fixed to the bottom of the cage frame 1. The overlapping frame 3 is located on both sides of the cage bottom plate 9, and one end of the overlapping frame 3 on the open side of the cage frame 1 extends outward. Secondary lifting lugs 6 and two sets of main lifting lugs 5 are welded to both sides of the cage frame 1. The extended portion of the overlapping frame 3... The main lifting lugs 5 can be placed on the floor slab and fixed to the floor slab with anchor bolts to prevent the cage from swaying up and down. The auxiliary lifting lugs 6 can be attached to one end of the wire rope to the floor to prevent the cage from swaying left and right, thus achieving efficient and safe pipe hoisting and unloading. Each set of main lifting lugs 5 consists of two main lifting lugs 5 arranged opposite each other. A rope-passing groove 21 is cut on one side of the cage net 2 of the main lifting lug 5. The wire rope suspended on the tower crane hook can pass through the rope-passing groove 21 and be attached to the main lifting lug 5 to avoid friction with the cage net 2 and affecting the wire rope. For safe rope use, one side of the extended portion of the overlapping frame 3 is welded to a wing plate of the positioning plate 7. The other wing plate of the positioning plate 7 has through holes for connecting bolts. The positioning plate 7 can be used to connect anchor bolts, ensuring the stability of the connection between the cage and the floor slab. The auxiliary lifting lugs 6 are arranged adjacent to the detachable protective door 4. One end of the hand-operated hoist is attached to the mega-column of the floor slab structure, and the other end is hooked onto the auxiliary lifting lugs 6 on both sides to prevent the cage from slipping outwards. The detachable protective door... Handles 8 are installed on the cage frame 1 on both sides of the protective door 4. The operator can hold the handles 8 to pull and adjust the horizontal position of the cage to ensure that the cage is placed in a suitable position. The four corners of the detachable protective door 4 are provided with through holes for sliding insertion lifting eye bolts 41. The lifting eye bolts 41 are threaded to the cage frame 1. The lifting eye bolts 41 can stably connect the detachable protective door 4 and the cage frame 1, and can be easily separated from the cage frame 1 after removal, so as to install and remove the pipeline.

[0020] The working principle of this technical solution is as follows: Start the tower crane and slowly lift the cage to the edge of the target floor. Operate the tower crane to gradually bring the extended part of the cage's lap frame 3 closer to the floor slab until the lap frame 3 is stably placed on the floor slab. At this time, the operator can conveniently adjust the horizontal position of the cage through the handle 8 on the cage frame 1, so that the through hole on the positioning plate 7 is aligned with the preset anchor bolt position on the floor slab. Insert the anchor bolts through the through holes of the positioning plate 7 and tighten the nuts to vertically fix the cage to the floor slab and prevent the cage from swaying up and down. Next, attach a hand-operated hoist to the structural column inside the floor, hook the other end of the hand-operated hoist to the auxiliary lifting lugs 6 on both sides of the cage, and tighten the hand-operated hoist appropriately to fix the cage by lateral pulling force to prevent it from sliding to the left or right or tilting to the outside. After the cage is fixed, remove the detachable protective door 4, unscrew the lifting eye bolts 41 at the four corners, and remove the protective door from the cage frame 1 to expose the opening side of the cage, which is convenient for loading and unloading pipes. If the pipe is hoisted from the ground to the cage, it can be hoisted to the opening side of the cage by a tower crane. Pull the traction rope reserved during the hoisting of the pipe to push the pipe from the bottom plate 9 of the cage to the designated position on the floor slab.
