[0002] Gantry cranes are the most common lifting equipment in heavy industrial units. They have lifting and lowering mechanisms, lifting beams, and operating mechanisms. Clamp slings are commonly used lifting equipment in metallurgical enterprises. They are lifted by bridge cranes to control the clamp slings to achieve the purpose of transferring goods. Clamp slings are divided into fixed lifting ears and chain lifting ears. This study mainly uses slab clamp slings with fixed lifting ears. At present, when using clamps, push-pull rods are mainly used to fix the direction of the bridge crane hook head with manual assistance, and move the hook head into the clamp lug. If the crane operation is wrong, it will cause great safety hazards to the personnel using the push-pull rod. Summary of the invention
[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a clamp sling auxiliary hook-in device, which can guide the hook head of the crane hook so that it can cooperate with the clamp lifting ear without human intervention during lifting to display the lifting work.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A clamp hanger auxiliary hooking device comprises a pull rod, a hanging plate is arranged on the top of the pull rod, a movable plate is symmetrically hinged on the bottom of the pull rod, a hinge rod is hinged on the end of the movable plate away from the pull rod, two hinge rods are cross-hinged at the center position, a clamp is arranged at the bottom of the two hinge rods, a hanger is arranged between the two hanging plates, and an auxiliary hooking mechanism is fixed on the front side of the hanging plate.
[0006] Furthermore, the auxiliary hook-entry mechanism is a guide plate welded on the front side of the hanging plate, and the two guide plates are distributed in an "eight" structure, and the distance between the two ends of the guide plates is greater than the other end.
[0007] Furthermore, the auxiliary hook-entry mechanism is a guide plate detachably mounted on the front side of the hanging plate, and the surface of the hanging plate is evenly provided with docking internal threaded holes.
[0008] Furthermore, an extension plate is provided on one side of the guide plate, the extension plate is placed on the outside of the hanging plate, a locking bolt passes through the surface of the extension plate, and the end of the locking bolt is screwed into the inside of the docking internal threaded hole.
[0009] Furthermore, a non-slip pad is fixed on the surface of one side where the clamps are close to each other.
[0010] Compared with the prior art, the beneficial effects of the utility model are: a guide plate with an "eight" structure distribution is fixedly provided on the front side of the hanging plate to guide the crane hook, so that the hook can smoothly enter between the two hanging plates and cooperate with the hanging rod to achieve fixation, and the coordination of the hook is achieved without human intervention, thereby ensuring the safety of the staff.

[0017] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model. Example
[0018] like Figure 1 and Figure 2 The illustrated embodiment is a clamp sling auxiliary hooking device, comprising a pull rod 1, a hanging plate 2 is arranged on the top of the pull rod 1, a movable plate 4 is symmetrically hinged at the bottom of the pull rod 1, a hinge rod 5 is hinged at one end of the movable plate 4 facing away from the pull rod 1, the two hinge rods 5 are cross-hinged at the center position, the two hinge rods 5 are provided with clamps 6 at the bottom, a suspension rod 3 is arranged between the two hanging plates 2, when the pull rod 1 is lifted by a crane, the two clamps 6 can be brought close to each other through the hinged hinge rods 5 to clamp the objects below to realize the lifting work, an anti-skid pad 7 is fixed to the surface of the side where the clamps 6 are close to each other, the anti-skid pad 7 is made of metal and has anti-skid patterns on the surface, the anti-skid pad 7 is fixed by bolts and can be disassembled and replaced.
[0019] Among them, an auxiliary hook-in mechanism is fixed on the front side of the hanging plate 2, and the auxiliary hook-in mechanism is a guide plate 8 welded on the front side of the hanging plate 2. The two guide plates 8 are distributed in an "eight" structure. The top height of the guide plate 8 is consistent with the axis height of the boom 3. The distance between the two ends of the guide plates 8 is greater than the other end, so as to guide the crane hook at all times, so that the hook automatically enters between the two hanging plates 2, and cooperates with the middle boom 3 to achieve lifting work.
