Description

Technical Field

[0001] The utility model relates to the technical field of track robots, in particular to a track robot with an emergency buffer device. Background Art

[0002] A track robot is a robot that can move on a track. It is usually composed of a robot body, a track, a control system, and sensors. Track robots are often used to transport materials in factories and warehouse logistics systems. However, the existing track robots have poor buffering performance. When a person or object from the outside accidentally breaks into the running path of the track robot and collides with it, due to the lack of buffering performance, it will cause greater impact damage. Therefore, in view of the above situation, it is urgent to develop a track robot with good buffering and absorption function to reduce the damage caused by accidental impact and an emergency buffer device, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0006] Preferably, the two rocker arms are arranged symmetrically about the center line of the bearing plate.

[0008] Preferably, a plurality of limiting wheels are rotatably mounted on both left and right sides of the interior of the frame, and the limiting wheels are in contact with the side surfaces of the track.

[0009] Preferably, a driving motor is fixed on the outer side of the frame, and an output shaft of the driving motor is connected to a roller.

[0010] The beneficial effects of the utility model are as follows: when the rail robot with an emergency buffer device is used, the material is placed in the transport box, the roller is driven to rotate by the driving motor, and the frame and the transport box are driven to move along the track by the rotation of the roller, so as to transport the material. When an external object accidentally breaks into the moving path of the transport box during operation, the buffer mechanism will first hit the object blocking the transport box, and the external object will first contact the protective pad, and the impact force will be buffered and absorbed by the protective pad.

[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 of 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] Specific examples are given below.

[0020] See also Figure 1~Figure 5 In the embodiment of the utility model, a rail robot with an emergency buffer device includes a rail 1, a frame 2, a transport box 3, a buffer mechanism 4, a roller 5, a limiting wheel 6 and a driving motor 7. The rail 1 is hung and fixed on the roof, the frame 2 is installed on the outside of the rail 1, and multiple rollers 5 are rotatably installed on the left and right sides of the frame 2. The rollers 5 are in contact with the rail 1, and multiple limiting wheels 6 are rotatably installed on the left and right sides of the frame 2. The limiting wheels 6 are in contact with the side of the rail 1. The frame 2 is limited to the left and right directions by the limiting wheels 6 to prevent it from moving left and right, and the frame 2 is controlled by the rollers 5 to move up and down. The position is limited to prevent it from moving up and down. A driving motor 7 is fixed to the outside of the frame 2. The output shaft of the driving motor 7 is connected to a roller 5. The driving motor 7 drives the roller 5 to rotate, and the rotation of the roller 5 drives the frame 2 to move along the track 1. A transport box 3 is fixedly connected to the lower side of the frame 2. The transport box 3 can store and transport materials. A buffer mechanism 4 is installed on the front and rear sides of the transport box 3. When an external object accidentally breaks into its moving path during operation, the buffer mechanism 4 will first hit the object blocking the transport box 3, thereby performing buffering and absorption to reduce the damage caused by the impact.

[0021] The buffer mechanism 4 includes: a load-bearing plate 401, a protective pad 402, a cross bar 403, a sliding sleeve 404, a swing rod 405, a first pin shaft 406, a second pin shaft 407, a spring 408, an extension block 409 and a damper 410. A protective pad 402 is installed on the front side of the load-bearing plate 401. The protective pad 402 is made of rubber material so that it has a certain elastic buffering capacity. The cross bar 403 is fixed on the transport box 3. Two sliding sleeves 404 are slidably installed on the cross bar 403. There are two swing rods 405. The two swing rods 405 are symmetrically arranged about the center line of the load-bearing plate 401. A plurality of springs 408 are connected between the two swing rods 405. One end of the swing rod 405 is rotatably connected to the load-bearing plate 401 through the first pin shaft 406, and the other end of the swing rod 405 is connected to the sliding sleeve through the second pin shaft 407. The sleeve 404 is rotatably connected, and an extension block 409 is fixed on the upper side of each sliding sleeve 404. Each extension block 409 is connected to a damper 410, and the damper 410 is fixed on the transport box 3. When an impact occurs, the external object first contacts the protection pad 402, and the protection pad 402 buffers and absorbs the impact force to a certain extent. The load-bearing plate 401 is displaced under the action of the impact force, and the displacement of the load-bearing plate 401 drives the swing rod 405 to swing, and the swing of the swing rod 405 drives the spring 408 to deform, and the impact force is buffered by the spring 408. At the same time, the swing of the swing rod 405 drives the sliding sleeve 404 and the extension block 409 to move, and the extension block 409 transmits the impact force to the damper 410, and the impact force is absorbed and converted by the damper 410, thereby reducing the damage caused by the impact.

[0022] Working principle: When the rail robot with emergency buffer device is in use, the material is placed in the transport box 3, and the roller 5 is driven to rotate by the driving motor 7. The rotation of the roller 5 drives the frame 2 and the transport box 3 to move along the track 1, so as to transport the material. When an external object accidentally breaks into the moving path of the transport box 3 during operation, the buffer mechanism 4 will first hit the object blocking the transport box 3, and the external object will first contact the protection pad 402, and the impact force will be buffered and absorbed by the protection pad 402. The load-bearing plate 401 will be displaced under the action of the impact force, and the displacement of the load-bearing plate 401 will drive the swing rod 405 to swing, and the swing of the swing rod 405 will drive the spring 408 to deform, and the impact force will be buffered by the spring 408. At the same time, the swing of the swing rod 405 drives the sliding sleeve 404 and the extension block 409 to move, and the extension block 409 will transmit the impact force to the damper 410, and the impact force will be absorbed and transformed by the damper 410, thereby reducing the damage caused by the impact.

[0023] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
