Description

Technical Field

[0001] This utility model relates to the field of crane hook technology, and in particular to a crane hook assembly. Background Technology

[0002] Cranes are essential equipment widely used in modern industry, construction, logistics, and other fields for lifting various heavy objects. As a key component of a crane, the hook assembly's performance directly affects the safety and efficiency of crane operations. With the continuous development of industrial production, higher demands are being placed on the lifting capacity and working efficiency of cranes.

[0003] The crane lifts the object to a high place using its hook, rotates it at a certain angle, and then places the object in a suitable position.

[0004] Existing crane hook assemblies are not convenient for controlling the direction of the hook, which increases the danger of hook rotation when lifting objects. At the same time, the hook itself is too large, making it inconvenient to manually adjust the direction of the hook. Therefore, a new type of crane hook assembly has been developed.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present utility model. This embodiment provides a crane hook assembly, including a hook 1, a sliding mechanism 2 provided on one side of the hook 1, and a rotating mechanism 3 provided on the top of the hook 1.

[0031] Specifically, the sliding mechanism 2 includes a grooved plate 201 fixedly disposed on one side of the hook 1, a slider 203 mounted on the inner surface of the grooved plate 201, and a loop handle 202 fixedly connected to one side of the slider 203.

[0032] Specifically, the interior of the grooved plate 201 is provided with several first holes evenly distributed, and a first spring 204 is provided in the hole. A limit bead 205 is fixedly installed at one end of the first spring 204. The slider 203 slides inside the grooved plate 201 and is stuck on the inner side of the grooved plate 201. The limit bead 205 is adapted to the slider 203.

[0033] Furthermore, under the action of the first spring 204, the limiting bead 205 can be pushed into the semi-circular groove that fits the slider 203. Under the action of the four limiting beads 205 on both sides of the slider 203, the slider 203 can be stabilized in the grooved bending plate 201. When it is necessary to change the force applied to one side of the hook 1, the boom handle 202 can be slid on the inner side of the grooved bending plate 201 to adjust its appropriate position, so as to facilitate the worker to hold the hook 1 for operation.

[0034] Example 2

[0035] Reference Figure 2 , Figure 5 ,and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a rotating mechanism 3 capable of changing the direction of the hook 1.

[0036] Specifically, the rotating mechanism 3 includes a T-shaped block 301 fixedly installed on the top of the hook 1, a circular block 302 is provided inside the T-shaped block 301, and a pulley frame 303 is fixedly connected to the top of the circular block 302.

[0037] Specifically, a top pin 305 is installed inside the round block 302, and a second spring 306 is fixedly installed on one side of the top pin 305. Push rods 304 are evenly distributed and movably inserted inside the T-shaped block 301. A limiting plate 307 is fixedly sleeved on the outer surface of the push rod 304. The T-shaped block 301 is movably sleeved on the outside of the round block 302. The top pin 305 is movably inserted into the inside of the round block 302. The limiting plate 307 is in the inner cavity of the T-shaped block 301.

[0038] Furthermore, after rotating the T-block 301 to a certain angle, the top pin 305 is pushed into the T-block 301 under the action of the second spring 306, thereby restricting the rotation of the T-block 301 and thus changing the suspension direction of the hook 1. When it is necessary to change the direction again, push the push rod 304 inward manually. The push rod 304 pushes the top pin 305 to the other side. Rotate the T-block 301 and rotate the top pin 305 to the side of the next push rod 304, thereby changing the direction of the slot of the hook 1.

[0039] Working principle: First, place the pulley bracket 303 on the outside of the suspension rope. Manually push the push rod 304. At this time, the push rod 304 drives the limiting plate 307 to move. The push rod 304 pushes the top pin 305 to one side. At this time, the second spring 306 is compressed. Manually rotate the T-block 301. The T-block 301 drives the hook 1 to change direction. After rotating to a suitable angle, under the action of the second spring 306, the top pin 305 is pushed to one side of the other push rod 304. At this time, under the action of the top pin 305, the T-block 301 and the round block 302 are kept relatively stationary. After rotating to the correct direction, hold the loop handle 202 and move the loop handle 202 around the grooved bending plate 201. During the movement, the loop handle 202 drives the slider 203 to move. At this time, under the action of the first spring 204, the first spring 204 pushes the limiting bead 205 into the slider 203, restricting the movement of the slider 203. The suspension rope is then suspended in the hook 1.

[0040] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
