AI Technical Summary
When existing cranes suspend and transport goods, the drop of goods poses safety hazards to surrounding workers and easily cause damage to the interior of the goods.
A buffer crane is designed, including the body, hanger, hook, cylinder, storage rack, slide rack, slide chute and buffer pad. The cushion is made of rubber material. The output shaft is driven to rotate through the cylinder, and the cushion is driven to slide in the slide groove to ensure that the cushion is directly under the cargo when the cargo falls, and plays a cushioning role.
When the goods fall, the buffer pad bends and deforms, which plays a buffering role, reduces safety hazards and cargo damage, and improves the safety and efficiency of cargo transportation.

Abstract
Description
Technical Field
[0001] The utility model relates to a buffer crane. Background Art
[0002] A crane is a mechanical device used to lift and transport goods. Its working principle is based on mechanical, hydraulic or electrodynamic principles. A crane is usually composed of a hook, a lifting arm, a support structure, a power system and a control system. Different types of cranes can be selected according to different work scenarios and needs. Its main function is to move goods from one location to another and ensure safe and efficient operations.
[0003] When existing cranes are used to suspend and transport goods, the goods may roll off the hooks due to the heavy weight of the goods or the goods not being tied tightly to the hooks, posing a safety hazard to the surrounding workers. In addition, the collision caused by the goods on the hook falling to the ground is likely to cause certain damage to the interior of the goods. Utility Model Content
[0004] The utility model aims to provide a buffer crane which can play a buffering role when goods fall, thereby reducing safety hazards and damage to goods.

[0006] A buffer crane comprises: a machine body; a hanger, which is arranged on the machine body; a hook, which is arranged at the end of the hanger; a cylinder, which is arranged on one side of the hanger and is used to adjust the angle of the hanger; a storage rack, which is arranged on the machine body and located at the bottom of the hanger; a sliding rack, which is arranged on the storage rack; a slide groove, which is arranged in the slide groove; and a buffer pad, which is slidably connected in the slide groove.
[0007] The utility model is further configured to include: a fixing plate, which is arranged at the end of the buffer pad; a connecting rod, one end of which is hinged to the fixing plate; a connecting block, which is hinged to the other end of the connecting rod; and an output shaft, which is arranged on the outside of the connecting block and fixedly connected to the cylinder.
[0008] The utility model is further configured as follows: the buffer pad is made of rubber material.
[0009] The utility model is further configured as follows: the output end of the cylinder is fixedly connected to the output shaft, and the cylinder drives the output shaft to rotate when working, and then drives the buffer pad to slide in the slide groove through the connecting rod and the fixed plate.
[0010] In summary, the utility model has the following beneficial effects: the buffer crane can play a buffering role when cargo falls, reducing safety hazards and cargo damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0015] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0016] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.
[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1 , Figure 2As shown, a buffer crane comprises a body 1. A hanger 2 is arranged on the body. A hook 3 is arranged at the end of the hanger 2. The hook 3 is used to carry suspended goods. A cylinder 4 for adjusting the angle of the hanger 2 is also arranged on one side of the hanger 2. The hook 3 can be connected to a corresponding pulley system for retracting and extending the hook 3.
[0019] The core technical solution of this application is as follows:
[0020] The machine body 1 is provided with a storage rack 5. The storage rack 5 is arranged at the bottom of the hanger 2 and fixedly connected to the machine body 1. The storage rack 5 is provided with a sliding rack 6. A slide groove 7 is arranged in the sliding rack 6. A buffer pad 8 is slidably connected in the slide groove 7. The buffer pad 8 is made of rubber material. A fixing plate 9 is arranged at the end of the buffer pad 8. A connecting rod 10 is hinged on one side of the fixing plate 9. A connecting block 11 is hinged on the top of the connecting rod 10. An output shaft 12 is arranged on the outer fixed sleeve of the connecting block 11. The output shaft 12 is fixedly connected to the cylinder 4.
[0021] As mentioned above, when the buffer pad 8 is moved out of the sliding frame 6, the buffer pad 8 is located directly below the cargo. When the cargo is suspended for transportation, the cargo accidentally falls from the hook 3 and falls onto the buffer pad 8. The buffer pad 8 bends and deforms, thereby providing a certain buffering effect on the cargo, reducing safety hazards and cargo damage.
[0022] The overall working process is as follows:
[0023] 1. Move the machine body 1 to the side of the cargo so that the hook 3 is on the upper side of the cargo. After the hook 3 is lowered to the cargo position, the cargo is suspended on the hook 3;
[0024] 2. The cylinder 4 drives the output shaft 12 to retract, so that the output shaft 12 gradually enters the cylinder 4. At this time, since the length of the connecting rod 10 is fixed, the connecting rod 10 drives the fixing plate 9 and the buffer pad 8 at the bottom to push outward, so that the buffer pad 8 moves out of the sliding frame 6;
[0025] 3. The buffer pad 8 enters under the cargo. When the cargo falls from the hook 3, it will first pass through the buffer pad 8. Under the bending deformation of the buffer pad 8, the buffer pad 8 can cushion the falling cargo and reduce the speed at which it falls to the ground, thereby reducing the possibility of damage to the cargo. The reduced speed can also reduce the safety hazards to the surrounding staff.
[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
