AI Technical Summary
Existing crane hooks are often left in a free-suspension state after use, posing a risk of slippage due to their own weight or crane swaying, which could potentially injure objects or people.
A hook counterweight clamping device was designed. The push rod and the top block cooperate with the baffle to clamp the hook through the electric cylinder. The linear bearing and buffer plate are used to ensure smooth movement and reduce impact. The surface of the top block is provided with friction particles to increase friction.
It effectively prevents the hook from falling due to external factors, improves safety, and avoids the risk of injuring objects or people.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of clamping devices, specifically relates to a hook counterweight block clamping device. BACKGROUND
[0002] The crane is a multi-motion hoisting machinery capable of vertically lifting and horizontally carrying heavy objects in a certain range, also known as a trolley, a hangar or a crane, and the hook is an important and key component of the crane and is used for suspending and lifting goods.
[0003] In the actual use process, the applicant finds that the hook part commonly used by the crane on the market is in a free suspension state after use, is not fixed in any way, and has the possibility of sliding and falling due to self-weight or shaking in the moving process of the crane, thereby having the risk of damaging objects and even injuring people. CONTENT OF THE UTILITY MODEL
[0004] In view of the problems in the above background technology, the utility model aims to provide a hook counterweight block clamping device.
[0005] In order to achieve the above technical purpose, the utility model adopts the following technical scheme:
[0006] A hook counterweight block clamping device, comprising a mounting seat, the mounting seat is provided with an element cavity, the mounting seat is connected with a baffle, a card mouth is formed between the element cavity and the baffle, a contact switch is installed on the upper side of the card mouth of the mounting seat;
[0007] The mounting seat is provided with an electric cylinder, the output end of the electric cylinder is connected with a sensing plate, a first travel switch and a second travel switch are installed in the element cavity, the sensing plate is located in the sensing range between the first travel switch and the second travel switch, a push rod is fixedly installed on the lower side of the sensing plate, the push rod is connected with a top block after penetrating through the element cavity, and the position of the top block corresponds to the baffle.
[0008] Further limited, the element cavity is provided with a linear bearing, and the push rod is located in the linear bearing, which ensures smooth movement of the push rod and also plays a supporting effect on the push rod.
[0009] Further limited, the mounting seat is provided with a buffer sheet, and the buffer sheet is located between the element cavity and the top block, which can buffer the hard collision of the element cavity outer wall when the top block is loosened and moved back, and can also reduce the sound caused by the impact.
[0010] Further limited, the mounting seat and the baffle are integrally formed, which ensures the overall strength and counteracts the top pressure of the top block.
[0011] Furthermore, the contact surface of the top block is uniformly provided with friction particles. This design increases friction, thereby increasing the clamping effect on the hook or the wire rope connected to it.
[0012] The beneficial effects of using this utility model are as follows:
[0013] The structural design of this utility model uses an electric cylinder to move the push rod, which allows the top block to work with the baffle to clamp the end of the hook. Under this clamping effect, the hook is less likely to fall off due to external factors, thus ensuring safety. Attached Figure Description

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1 , Figure 2 As shown, a hook counterweight clamping device of the present invention includes a mounting base 1, a component cavity 2 provided on the mounting base 1, a baffle 3 connected to the mounting base 1, a bayonet 4 formed between the component cavity 2 and the baffle 3, and a contact switch 5 installed on the upper side of the bayonet 4 on the mounting base 1.
[0021] The mounting base 1 is equipped with an electric cylinder 6. The output end of the electric cylinder 6 is connected to an induction plate 7. The component cavity 2 is equipped with a first limit switch 8 and a second limit switch 9. The induction plate 7 is located within the sensing range between the first limit switch 8 and the second limit switch 9. A push rod 10 is fixedly installed on the lower side of the induction plate 7. The push rod 10 passes through the component cavity 2 and is connected to a top block 11. The position of the top block 11 corresponds to the baffle 3.
[0022] In the embodiment, when the hook weight clamping device is used, the upper end of the hook weight located in the bayonet 4 contacts the contact switch 5 when the hook weight is pulled back to the highest point by the connected steel wire rope and stops working, the contact switch 5 receives the signal, transmits the signal to the electric cylinder 6, controls the operation of the electric cylinder 6, and the electric cylinder 6 drives the inductive plate 7 to move towards the bayonet 4, the movement of the inductive plate 7 drives the push rod 10 to move, and then the push block 11 is moved towards the hook, and the clamping of the hook is realized by cooperating with the baffle 3. The installation of the second travel switch 9 ensures that the inductive plate 7 moves forward to the right position, and the clamping is in place. The installation of the first travel switch 8 ensures that the inductive plate 7 moves back to the right position, and the purpose of completely releasing is achieved, preventing interference with the normal use of the hook in use.
[0023] Preferably, the element cavity 2 is provided with a linear bearing 12, and the push rod 10 is located in the linear bearing 12. Such a design ensures smooth movement of the push rod 10 and also provides support for the push rod 10. In fact, the support sliding structure of the push rod 10 can also be considered according to specific conditions.
[0024] Preferably, the mounting seat 1 is provided with a buffer piece 13 located between the element cavity 2 and the push block 11. Such a design can buffer the hard collision of the element cavity 2 outer wall when the push block 11 is released and moved back, and can also reduce the sound caused by the impact. In fact, the structure and material of the buffer piece 13 can also be considered according to specific conditions.
[0025] Preferably, the mounting seat 1 and the baffle 3 are integrally formed. Such a design ensures the overall strength and counteracts the pressure of the push block 11. In fact, the forming method of the mounting seat 1 and the baffle 3 can also be considered according to specific conditions.
[0026] Preferably, the contact surface of the push block 11 is uniformly provided with friction particles. Such a design increases the friction and further increases the clamping effect on the hook or the connected steel wire rope. In fact, measures to enhance the clamping effect can also be considered according to specific conditions.
