DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 4 The utility model discloses a crane hoisting hook, comprising a hook body 1, a limit assembly 2 is arranged at the hook tip of the hook body 1, a slot 3 is opened on one side close to the top of the hook body 1, a connecting assembly 4 is arranged in the slot 3, and a mounting assembly 5 is arranged at the top of the hook body 1.
[0020] In this embodiment, the hook body 1 and the starter are installed by means of the installation component 5, the lifting rope is manually placed at the stress-bearing position of the hook body 1, and the opening of the hook body 1 is blocked by means of the limiting component 2 and the connecting component 4. The opening of the hook body 1 can be blocked to prevent the lifting rope from detaching from the hook body 1 during use.
[0021] Specifically, the connecting component 4 includes a fixing rod 401, a limiting rod 402 and a limiting groove 403. The two ends of the fixing rod 401 are fixedly connected to the inner wall of the slot 3. The limiting rod 402 is sleeved on the fixing rod 401 and rotatably connected to the fixing rod 401. The limiting groove 403 is opened on the side near the other end of the limiting rod 402.
[0022] In this embodiment, when the opening of the hook body 1 needs to be blocked, the limiting rod 402 is manually rotated so that the limiting rod 402 rotates along the fixing rod 401 .
[0023] Specifically, the limit assembly 2 includes a fixed box 201, a slider 202, an arc-shaped plate 203, a support rod 204, a spring 205, a fixed block 206 and a fixed groove 207. One side of the fixed box 201 is opened, the slider 202 is arranged in the fixed box 201 and slides with the inner wall of the fixed box 201, the arc plate 203 is fixedly connected to the slider 202, one end of the support rod 204 is fixedly connected to the slider 202, and the other end passes through the fixed box 201 and slides with the fixed box 201, the spring 205 is sleeved on the support rod 204, and the two ends of the spring 205 are respectively fixedly connected to the slider 202 and the inner wall of the fixed box 201, the bottom of the fixed block 206 is fixedly connected to the hook tip of the hook body 1, and the fixed groove 207 is opened on the fixed block 206, and the fixed groove 207 and the arc plate 203 are on the same horizontal line.
[0024] When the limit rod 402 is moved to contact with the hook tip of the hook body 1, it will no longer move. At this time, the limit groove 403 is on the same horizontal line as the fixed groove 207 and the curved plate 203. At this time, the curved plate 203 is not squeezed by the limit plate. At this time, the spring 205 drives the slider 202, the support rod 204 and the curved plate 203 to move along the inner wall of the fixed box 201. The arc block 206 is disengaged from the fixing groove 207 and the limiting groove 403, and the limiting rod 402 is manually pulled out from between the fixing block 206 and the fixing box 201. When the supporting rod 204 is no longer manually pulled, the spring 205 drives the sliding block 202, the supporting rod 204 and the arc block to move, so that the arc block enters the fixing groove 207, which can block the opening of the hook body 1 and prevent the hanging rope from shaking and disengaging from the hook body 1 during use.
[0025] Specifically, the mounting assembly 5 includes a mounting rod 501 and a threaded groove 502 . The bottom of the mounting rod 501 is fixedly connected to the top of the hook body 1 , and the threaded rod is provided on the mounting rod 501 .
[0026] In this embodiment, the hook body 1 is connected to the crane through the threaded rod groove.
[0027] Specifically, a rectangular groove 6 is provided at a stress-bearing position of the hook body 1 .
[0028] In this embodiment, by placing the hanging rope in the rectangular groove 6 , the hanging rope is further prevented from being separated from the hook body 1 .
[0029] Specifically, the support rod 204 passes through the other end of the fixed box 201 and is fixedly mounted with a baffle 7 .
[0030] In this embodiment, the support rod 204 is more conveniently pulled by the baffle 7 .
[0031] Specifically, the hook body 1 and the limiting component 2 are sprayed with anti-corrosion paint.
[0032] In this embodiment, anti-corrosion paint is sprayed on the hook body 1 to prevent corrosion and increase the service life.
[0033] The working principle and use process of the utility model are as follows: when in use, the hook body 1 is connected to the crane through the threaded rod groove, the lifting rope is manually placed at the force-bearing position of the hook body 1 and is located in the rectangular groove 6, and the limit rod 402 is manually rotated, and the limit rod 402 rotates along the fixed rod 401. When the limit rod 402 rotates to the arc plate 203, the limit rod 402 is located between the fixed block 206 and the fixed box 201, and is against the inclined surface of the arc plate 203. The positioning plate squeezes the inclined surface of the arc plate 203, so that the arc plate 203 pushes the slider 202, and the slider 202 drives the support rod 204 to move along the inner wall of the fixed box 201. At the same time, the spring 205 is squeezed by the slider 202. At this time, the arc plate 203 will abut against one side of the limiting rod 402. When the limiting rod 402 moves to abut against the hook tip of the hook body 1, it will no longer move. At this time, the limiting groove 403 is on the same horizontal line with the fixed groove 207 and the arc plate 203. At this time, the arc plate 203 is not squeezed by the limiting plate. At this time, the spring 205 drives the slider 202, the support rod 204 and the arc plate 203 to move along the inner wall of the fixed phase, so that the arc plate 203 passes through the limiting groove 403 and enters the fixed groove 207. The limiting rod 402 is fixed by the arc plate 203 and the fixed groove 207, and the opening of the hook body 1 is blocked by the limiting rod 402. When the hanging rope needs to be taken out from the hook body 1, the support rod 204 is manually pulled to drive the slider 202 and the arc plate 203 to move. The arc block moves, so that the spring 205 is squeezed, and the arc block will be separated from the fixed groove 207 and the limiting groove 403. The limiting rod 402 is manually removed from between the fixed block 206 and the fixed box 201. When the support rod 204 is no longer pulled manually, the spring 205 drives the slider 202, the support rod 204 and the arc block to move, so that the arc block enters the fixed groove 207, which can block the opening of the hook body 1 and prevent the rope from escaping from the hook body 1 during use.
