Description

Technical Field

[0001] The utility model relates to the field of hangers, in particular to a rotating hanger for a tower base component. Background Art

[0002] At present, a Chinese utility model with the announcement number CN221420419U discloses a hanger for metal casting, including a clamp hanger body and a clamping part. The utility model discloses that a lifting lug is arranged on the top of the clamp hanger body, and the clamp hanger body includes a connecting arm and a clamping arm. There are two connecting arms and two clamping arms. The upper ends of the two connecting arms are rotatably connected, and the lower ends of the connecting arms are rotatably connected to the upper ends of the clamping arms. The two clamping arms are rotatably connected in the middle after crossing each other. The clamping part is fixedly arranged below the clamping arm, and a detachable widening structure is installed on both sides of the clamping part, that is, a first clamping block is detachably arranged on both sides of the clamping part. The clamping surface of the clamping part is detachably installed with a side plate, and an anti-fall hook is arranged at the lower end of the clamping arm;

[0003] Although the existing hoist can rotate the clamping seat with the cooperation of the fixed rod, there are still other problems in the use process, such as the lack of lateral spacing adjustment function, the natural opening stroke between the two clamping seats is short when the hoist is lowered, and if the tower seat to be lifted is small, the clamping seat will not be able to contact the tower seat, the applicability and flexibility are poor, and it is not convenient to quickly disassemble and assemble the seat. When the seat is severely worn or damaged after use, personnel are required to replace the seat. When replacing the seat, they can only use tools to remove the bolts used to fix the seat, which reduces the work efficiency of personnel. In order to solve the above-mentioned problems, we propose a rotating hoist for tower seat components. Utility Model Content

[0004] The utility model aims to provide a rotary hanger for a tower base component, which solves the problem that the existing rotary hanger has no lateral spacing adjustment function and is inconvenient for personnel to quickly disassemble and assemble the clamping seat.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a rotating hoist for a tower base component, comprising a first connecting arm, the front side of the first connecting arm is rotatably connected to the second connecting arm, the top of the first connecting arm is provided with a lifting ear, the tops of the first connecting arm and the second connecting arm are both connected with a connecting rope through a through hole, the first connecting arm and the second connecting arm are both threadedly connected to a threaded rod on the back side thereof, the other end of the threaded rod is rotatably connected to a connecting plate through a bearing, one side of the connecting plate is rotatably connected to a shell through a rotating shaft, a connecting block is penetrated on one side of the shell, a clamping seat is welded on the other side of the connecting block, two movable plates are arranged inside the shell, the top and bottom of the connecting block are clamped with limit blocks welded to the movable plate through a slot, and a fixing spring is bolted between the other side of the movable plate and the shell through a spring fixing sheet.

[0006] The above technical solution can provide a lateral spacing adjustment function to meet the size requirements of various workpieces, improve the applicability and flexibility of the sling, and at the same time facilitate personnel to quickly disassemble and assemble the card holder, the operation is simple and convenient, the work efficiency of personnel is improved, and the practicability is high.

[0007] The utility model is further configured as follows: a fixing rod is welded on the other side of the movable plate, and the other end of the fixing rod penetrates the outside of the shell and is welded with a pulling plate.

[0008] By adopting the above technical solution, through the arrangement of the fixed rod and the pulling plate, it is convenient for personnel to pull the movable plate outward.

[0009] The utility model is further configured as follows: a fixing plate is bolted to the front side of the first connecting arm.

[0010] By adopting the above technical solution, the second connecting arm can be limited by setting the fixing plate, thereby improving the stability between the first connecting arm and the second connecting arm.

[0011] The utility model is further configured as follows: the connecting rope is made of steel wire rope.

[0012] By adopting the above technical solution, the connecting rope is wear-resistant, tensile-resistant, moisture-resistant, flexible, and elastic, and can withstand impact loads.

[0013] The utility model is further configured as follows: limiting rods are welded on the back-to-back sides of the two connecting plates, and the other ends of the two limiting rods respectively penetrate and extend to the outside of the first connecting arm and the second connecting arm.

[0014] By adopting the above technical solution, the connection plate can be limited by setting the limit rod to prevent the connection plate from turning over when it moves horizontally to the left or right.

[0015] The utility model is further configured as follows: a turning handle is welded on the other end of the threaded rod.

[0016] By adopting the above technical solution and setting the turning handle, it is convenient for personnel to rotate the threaded rod.

[0017] The utility model is further configured as follows: a rubber protective pad is bolted inside the clamping seat.

[0018] By adopting the above technical solution, the tower base component can be protected by providing a rubber protective pad, thereby preventing the surface of the component from being scratched when the clamping seat drives the component to rise.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model lowers the sling first, and then two clamping seats are located on both sides of the component. When the component is too small, the threaded rod is rotated by holding the handle by hand. When the threaded rod rotates, it drives the connecting plate to move inward through the cooperation of the bearing and the limit rod. When the connecting plate moves inward, it drives the shell and the clamping seat to move inward together. When the clamping seat is engaged with the component, the lifting ear can be pulled to lift the component. The utility model has the function of adjusting the horizontal spacing to meet the size requirements of various workpieces, thereby improving the application range and flexibility of the sling.

[0021] 2. The utility model allows the two pull plates to be grasped by hand and pulled outward. When the pull plates are pulled outward, the movable plates are driven to move outward through the fixation of the fixed rods. When the movable plates move outward, the limit blocks are driven to separate from the card slots on the connecting blocks. When the pull plates are pulled out to the bottom, the clamping base can be directly grasped and pulled out. This allows personnel to quickly disassemble and assemble the base, is simple and convenient to operate, improves personnel's work efficiency, and is highly practical.
