Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hooks, in particular to an anti-drop hook. Background Art
[0002] A hook is a tool used to hang or lift heavy objects, and is commonly used in cranes, hoists, chain hoists and other equipment. The hook is mainly composed of a curved steel hook body, a hook mouth and a wire rope connection seat. It has a simple and practical structure and has the characteristics of strong load-bearing capacity, light weight and easy operation. When in use, the hook is connected to the pulley of the crane or hoist, and then the load is hung on the hook, and then the load is moved by the lifting and lowering of the pulley.
[0003] In order to ensure that the goods are more stable during the rising process, an anti-slip device will be installed on the surface of the hook to prevent the goods from falling off. The common anti-slip device on the market is to install an anti-slip part on the inner side of the hook, and an elastic part is set at one end of the anti-slip part so that the other end of the anti-slip part is tightly against the inner tip of the hook, so as to achieve the anti-slip effect.
[0004] However, during the lifting process, the anti-slip part frequently contacts the inner tip of the hook, causing severe wear at the position where the anti-slip part contacts the hook, causing the wire rope on the hook to easily fall off. The anti-slip part cannot play a role in preventing it from falling off, posing a safety hazard to the workers. Utility Model Content
[0005] The utility model aims to provide an anti-dropping hook to solve the problem that the existing anti-dropping device of the hook cannot play the anti-dropping role due to serious wear and tear on the hook, thus causing safety hazards.
[0006] To achieve the above-mentioned purpose, the basic scheme provided by the utility model is: an anti-slip hook, comprising a pulley and an anti-slip mechanism, the pulley is rotatably connected to a hook body, the anti-slip mechanism comprises a sleeve one, the sleeve one is fixedly connected to the outer wall of the hook body, the sleeve one is fixedly connected to a sleeve two, the sleeve two is rotatably connected to a rotating shaft, the two ends of the rotating shaft are respectively fixedly connected to an anti-slip plate and a limiting frame, the anti-slip plate is located on the inner side of the hook body, the limiting frame is located on the rear side of the hook body, the sleeve one is fixedly connected to a support plate, a spring is fixedly connected between the limiting frame and the support plate, connecting plates are provided on both sides of the sleeve one, and a spring rod is hinged between the anti-slip plate and the connecting plate.
[0007] The working principle of the utility model is as follows: when it is necessary to use a hook to lift goods, first pull the limit frame upward so that the wire rope can be hooked on the inner side of the hook body. After all the wire ropes are hooked, release the limit frame. At this time, since the expansion and contraction forces of the spring and the spring rod are equal, the anti-drop plate will bounce back to its original position. Then, the goods are lifted by the cooperation of the crane and the pulley and transported to the destination. After the goods are placed, pull the limit frame upward again, remove the wire rope of the goods from the hook body, and finally release the limit frame.
[0008] The beneficial effects of the utility model are as follows: an anti-slip mechanism is arranged at the opening of the hook for protection to prevent the suspended goods from slipping out; by arranging a spring rod and a spring with the same elastic coefficient, the spring rod offsets the compression force released by the spring, effectively avoiding the ineffective anti-slipping caused by the wear of the anti-slip frame and the hook, thereby increasing safety and ensuring the anti-slipping effect of the anti-slip mechanism. The heavy objects can be taken and placed by pulling up the limit frame. It is quick and easy to use, more durable than previous anti-slip devices, more convenient and safer to use, and easier to install.
[0009] Option 2, which is a preferred option of the basic option, is characterized in that a connecting block and a protrusion are respectively provided at both ends of the spring rod, a rotating rod 1 is rotatably connected to the connecting block, one end of the rotating rod 1 is fixedly connected to the connecting plate, a rotating rod 2 is rotatably connected to the protrusion, both ends of the rotating rod 2 are fixedly connected to fixed blocks, and the fixed blocks are fixedly connected to the anti-slip plate.
[0010] Option three is a preferred option of the basic option. A limit block is fixedly connected to the connecting plate, and one end of the limit block is against the spring rod. The limit block is arranged on the connecting plate to limit the unlimited upward movement of the spring rod, thereby preventing the anti-slip plate from slipping.
[0011] Option 4 is a preferred option of the basic option. The two sides of the pulley are bolted with triangular clamps. The triangular clamps are arranged on both sides of the pulley to facilitate the stability of the pulley and prevent the hook from tilting.
[0012] Option 5, which is a preferred option of the basic option, is that grooves are provided on the limit frame and the support plate; the grooves are provided on the limit frame and the support plate for the limit spring.
[0013] Option six, which is the preferred option of the basic option, the angle between the limit frame and the anti-slip plate is greater than or equal to 90°. BRIEF DESCRIPTION OF THE DRAWINGS
