[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. Cranes generally move objects through lifting devices such as hooks. Some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of actions such as picking up materials, transporting, and unloading work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive. During the handling process, there will be many dangerous factors that endanger the lives of workers. In recent years, crane accidents have occurred many times, and most of them are caused by broken ropes due to different operating conditions and harsh working environment.

[0003] Usually a bridge crane is used for lifting and loading. However, traditional bridge cranes lift rebar coils by tying them with ropes, and the tying ropes are removed after loading. The operation is cumbersome and labor-intensive, and the center of gravity of the rebar coils tied with ropes is unstable, resulting in low operating efficiency and high safety hazards.

The pulley block 12 slides on the top of the sliding beam 11 through the first motor 3 to achieve the function of moving the transported object. The sliding block 14 slides on the bottom of the main beam 13 to increase the flexibility of the transported object. The rope 17 inside the electric hoist 15 is controlled by the second motor 16 to retract. One side of the rope 17 is connected to the processing mechanism 2, and the processing mechanism 2 plays a clamping and fixing role on the object. The electric hoist 15 controls the rope 17 to lift, and then the above-mentioned components are operated to achieve the transportation and delivery of the object. In the process of the rope 17 shrinking to the inside of the electric hoist 15, it is frictionally adapted with the guide mechanism 18, and the guide mechanism 18 plays a role in guiding the component to shrink and prevent entanglement. Secondly, it plays a buffering role when contacting with the processing mechanism 2 to avoid collision with components during the lifting process, prevent excessive shaking of the object, reduce the probability of object unhooking, and improve operation safety.

[0022] The guide mechanism 18 includes a guide frame 181, the top of the guide frame 181 is fixedly connected to the outside of the electric hoist 15, the bottom of the guide frame 181 is fixedly connected to a connecting bracket 182, the inner side of the connecting bracket 182 is fixedly connected to a spring rod 183, and the bottom of the connecting bracket 182 is rotatably connected to a round block 184. The rope 17 passes through the guide frame 181 and is connected to the top of the processing mechanism 2. When the rope 17 is extended and retracted through the electric hoist 15, it is frictionally adapted with the round block 184, thereby achieving the function of guiding the extension and retraction of the component, improving the stability of the extension and retraction of the component, thereby maintaining the movement trajectory of the rope 17 and improving the working efficiency. Secondly, when the rope 17 drives the processing mechanism 2 to lift and move toward the electric hoist 15, when the external pressure causes the connecting bracket 182 to squeeze the spring rod 183, the spring structure plays a role of shock absorption and buffering, reducing the vibration amplitude of the component, improving the stability of the component, and preventing the component from being over-lifted and colliding with the equipment, thereby playing a certain protective effect on the component.

Secondly, the heat dissipation effect of the component is enhanced by opening the groove, reducing local friction overheating and avoiding affecting the performance of the component.

[0024] The second embodiment is based on the first embodiment. Figures 5 to 7 As shown, the limiting mechanism 19 includes a limiting frame 191, the inner side of the limiting frame 191 is fixedly connected to a limiting shell 192, the inner side of the limiting shell 192 is fixedly connected to a first spring 193, the outer side of the first spring 193 is fixedly connected to a sliding rod 194, the outer side of the sliding rod 194 is slidably connected to the inner wall of the limiting shell 192, the inner wall of the limiting shell 192 is fixedly connected to a friction mechanism 195, and the outer side of the sliding rod 194 away from the first spring 193 is fixedly connected to a buffer mechanism 196. When the sliding block 14 slides on the sliding beam 11, when the external pressure squeezes the sliding rod 194, the sliding rod 194 squeezes and contracts the first spring 193, thereby playing a role of shock absorption and buffering, and has a certain limiting effect on the sliding of components, avoiding excessive sliding of components and derailment. The elastic deformation of the spring can absorb the kinetic energy during impact and convert mechanical energy into elastic potential energy, thereby extending the impact time and reducing the instantaneous impact force, which has a certain protective effect on the components. When the external pressure ends, the reaction of the first spring 193 causes the sliding rod 194 to rub against the friction mechanism 195, thereby slowing down the reaction of component braking, improving the stability of the components, reducing the wear between the components, and thus extending the service life of the components.

When one side of the outside of the sliding rod 194 is subjected to external impact, the first plate 1961 is driven to control the connecting bracket 1962 to be squeezed toward the second plate 1963, so that the third spring 1964 is compressed under pressure, thereby achieving a shock-absorbing and buffering effect, achieving a double buffering effect on the limiting mechanism 19, further improving the shock-absorbing effect, achieving a certain protection effect on the components, absorbing the impact kinetic energy in stages, improving the buffering efficiency, and enhancing the safety of the equipment.

[0027] The third embodiment is based on the first and second embodiments. Figures 8 to 10 As shown, the processing mechanism 2 includes a processing top plate 21, and the two sides of the top of the processing top plate 21 are fixedly connected with slide rail blocks 22, and the inner side of the slide rail block 22 is slidably connected with a moving block 23, and the bottom of the moving block 23 is fixedly connected with a support frame 24, and the outer side of the support frame 24 away from the moving block 23 is fixedly connected with a first clamping plate 25. When the moving block 23 slides inside the slide rail block 22, the support frame 24 controls the first clamping plate 25 to move toward the middle of the processing top plate 21, so as to achieve the function of clamping and fixing the object, and the subsequent transportation is facilitated by fixing the object.

[0028] An electric push rod 26 is fixedly connected to one side of the outside of the first clamping plate 25, a second clamping plate 27 is fixedly connected to one side of the outside of the electric push rod 26 away from the first clamping plate 25, and a pressure relief mechanism 28 is fixedly connected to one side of the second clamping plate 27 away from the first clamping plate 25. The electric push rod 26 controls the first clamping plate 25 to extend and retract, thereby playing a role in the detailed regulation of the clamping range, improving the applicable scope of the components, and facilitating the clamping of objects with small volume and high density. At the same time, when the electric push rod 26 clamps the object, the object is clamped toward the middle of the processing top plate 21, so that the object is in the middle position, which plays a certain positioning effect, balances the load, disperses the pressure, enhances the stability, prevents tilting or falling off, and facilitates accurate positioning and operation. The pressure relief mechanism 28 plays a role in buffering the clamping pressure and reducing the wear between the object and the components.

[0029] The pressure reducing mechanism 28 includes a trapezoidal plate 281, a connecting rod 282 is fixedly connected to one side of the trapezoidal plate 281 close to the second clamping plate 27, a fourth spring 283 is sleeved on the outer side of the connecting rod 282, the outer side of the connecting rod 282 is slidably connected to the outer side of the second clamping plate 27, and silicone blocks 285 are fixedly connected to both sides of the trapezoidal plate 281 away from the connecting rod 282, and a bevel groove 286 is provided on the outer side of the silicone block 285. When the trapezoidal plate 281 contacts the surface of the object, the reaction of the surface of the object during clamping causes the trapezoidal plate 281 to drive the connecting rod 282 to move toward the second clamping plate 27, compressing the fourth spring 283, thereby absorbing impact energy and protecting objects and equipment. Through elastic deformation or energy dissipation, the impact force in the clamping process is converted into potential energy or heat energy to avoid damage to objects or equipment caused by rigid collisions. Shock reduction and noise reduction improve the stability of operation, reduce jitter in clamping movement, and ensure processing accuracy. The silicone block 285 is made of silicone material, which protects the components and avoids serious wear of the components after long-term operation, thereby avoiding affecting the clamping effect. Secondly, by opening a bevel groove 286, the buffering and shock absorption effects are enhanced through the grooves.

[0030] When in use, the composite mechanism 1 is connected to the processing mechanism 2, and the internal moving block 23 of the processing mechanism 2 slides on the inner side of the slide rail block 22, so that the support frame 24 controls the first clamping plate 25 to move toward the middle of the processing top plate 21, so as to achieve the function of clamping the object. In the process of clamping the object, the decompression mechanism 28 plays a certain buffering and shock absorbing effect in the process of clamping the object. Through elastic deformation or energy dissipation, the impact force in the clamping process is converted into potential energy or heat energy, avoiding rigid collision that causes damage to the object or equipment. Shock absorption and noise reduction improve the stability of the operation, reduce the jitter in the clamping movement, and ensure the processing accuracy. After the object is clamped and fixed by the processing mechanism 2, the composite mechanism The second motor 16 inside the electric hoist 15 controls the rope 17 inside the electric hoist 15 to contract, thereby driving the processing mechanism 2 to be lifted, so as to facilitate subsequent handling and movement. During the contraction of the rope 17, friction adaptation is performed with the guide mechanism 18, and the rope 17 is guided by the guide mechanism 18 to be extended and retracted, so as to maintain the extension and retraction trajectory of the component and avoid the occurrence of disengagement. At the same time, the guide mechanism 18 reduces the vibration amplitude of the component, improves the stability of the component, and prevents the component from being over-lifted and colliding with the equipment, thereby playing a certain protective effect on the component. Then, the pulley group 12 drives the main beam 13 to move, so as to achieve the function of carrying and conveying objects, so as to achieve the function of reciprocating operation.
