[0001] This utility model relates to the field of robotics technology, specifically to a multifunctional robot for post-disaster reconstruction. Background Technology

[0002] Following natural disasters, damaged roads reduce transportation efficiency, preventing traditional construction machinery from quickly reaching the site.

Existing technologies utilize unmanned vehicles equipped with buckets to assist workers in clearing obstacles; however, these vehicles have limited functionality and cleaning capabilities, failing to meet the demands of complex and demanding disaster cleanup operations. Therefore, a multi-functional disaster reconstruction robot with strong cleaning capabilities is needed. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional robot for post-disaster reconstruction, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional robot for post-disaster reconstruction, comprising a walking chassis, a bucket rotatably disposed at the front of the walking chassis, one end of a sliding hydraulic cylinder rotatably disposed inside the walking chassis, the other end of the sliding hydraulic cylinder rotatably disposed under a back plate, the back plate being able to contact the walking chassis, one end of a telescopic rod rotatably disposed under the back plate, the other end of the telescopic rod rotatably disposed inside the walking chassis;

A pad is fixed on the wheel frame, and pulleys A and C are rotatably mounted on the wheel frame. A pulley B is rotatably mounted on the traveling chassis at the lifting hydraulic cylinder. A fixed end of a chain is fixed on the traveling chassis, and the free end of the chain passes around pulley A down to pulley B, then around pulley B up to pulley C, and then around pulley C again to be detachably connected to the material.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: such as Figure 1 , 2 As shown, a multifunctional robot for post-disaster reconstruction includes a walking chassis 1. A bucket 2 is rotatably mounted at the front of the walking chassis 1. One end of a sliding hydraulic cylinder 3 is rotatably mounted inside the walking chassis 1. The other end of the sliding hydraulic cylinder 3 is rotatably mounted under a back plate 4, which can contact the walking chassis 1. One end of a telescopic rod 5 is rotatably mounted under the back plate 4, and the other end of the telescopic rod 5 is rotatably mounted inside the walking chassis 1.

[0026] It moves via the chassis 1 and can remove obstacles via the bucket 2, making it easy for workers to operate.

[0027] like Figure 2 As shown, one end of the telescopic rod 5 is rotatably equipped with a tilting hydraulic cylinder 6, and the other end of the tilting hydraulic cylinder 6 is rotatably installed inside the walking chassis 1.

[0028] The backplate 4 extends beyond the chassis 1 by shortening the sliding hydraulic cylinder 3 (shown in...). Figure 1 In the middle section, the extension of the back plate 4 can cause the telescopic rod 5 to shorten, and then the tilting hydraulic cylinder 6 extends, thereby causing the telescopic rod 5 to rotate, which in turn causes the back plate 4 to move, so that the part of the back plate 4 that extends outside the chassis 1 lands on the ground (shown in the middle section). Figure 3 (in the middle), to facilitate staff to place material 14 (shown in) Figure 3 (Middle) Move it onto the back panel 4.

[0029] like Figure 1 , 3As shown, one end of a lifting hydraulic cylinder 7 is fixed on the traveling chassis 1, and a wheel frame 8 is fixed on the other end of the lifting hydraulic cylinder 7. A pad block 9 is fixed on the wheel frame 8. A pulley 10 and a pulley 12 are rotatably mounted on the wheel frame 8. A pulley 11 is rotatably mounted on the traveling chassis 1 at the location of the lifting hydraulic cylinder 7. A fixed end of a chain 13 is fixed on the traveling chassis 1. The free end of the chain 13 passes around the pulley 10 and goes down to the pulley 11, then passes around the pulley 11 and goes up to the pulley 12, and then passes around the pulley 12 and is detachably connected to the material 14.

[0030] The operator secures the material 14 to the free end of the chain 13 (as shown in the diagram). Figure 3 (In the middle), then the lifting hydraulic cylinder 7 extends, which in turn drives the wheel frame 8 to rise, which in turn drives pulley A 10 and pulley C 12 to rise, which in turn drives the free end of chain 13 to move in the direction of lifting hydraulic cylinder 7, which in turn drives material 14 to move towards back plate 4, which can reduce the labor intensity of workers.

[0031] The rising of the wheel frame 8 can drive pulleys A 10 and C 12 to rise, increasing the distance between pulleys A 10 and B 11, the distance between pulley A 10 and the fixed end of chain 13, and the distance between pulley C 12 and B 11. That is, for every unit length that the wheel frame 8 rises, the free end of chain 13 moves three units of length, expanding the stroke of the free end of chain 13, which makes it easier to pull the material 14 onto the back plate 4.

[0032] The robot first moves under the obstacle, and then lifts the obstacle using the lifting hydraulic cylinder 7, making it easier for the operator to operate. When the lifting hydraulic cylinder 7 lifts the obstacle, the bucket 2 presses the ground to improve the stability of the walking chassis 1.

[0033] like Figure 2 As shown, in order to improve the stability of the bucket 2, the bucket 2 includes two side walls 15, each of which is rotatably disposed on the side of the traveling chassis 1, and a connecting plate 16 is fixed between the two side walls 15.

[0034] like Figure 2 As shown, in order to facilitate driving the bucket 2, a drive shaft 17 is fixed between the two side walls 15. A driven sprocket is fixed on the drive shaft 17. The driven sprocket is connected to the drive sprocket through a roller chain 18. The drive sprocket is fixed on the output shaft of the drive motor 19. The drive motor 19 is fixed inside the traveling chassis 1.

[0035] The drive motor 19 can drive the drive sprocket to rotate, which in turn drives the driven sprocket to rotate through the roller chain 18, which in turn drives the drive shaft 17 to rotate, which in turn drives the side wall to rotate, which in turn drives the connecting plate 16 to rotate.

[0036] like Figure 1As shown, anti-slip textures are fixed on the pad 9 to prevent slippage when lifting obstacles.

[0037] like Figure 4 As shown, a chain retainer plate 20 is fixed on the wheel frame 8 to prevent the chain 13 from falling off.

[0038] like Figure 1 As shown, in order to improve the robot's mobility, the walking chassis 1 is a tracked chassis.

[0039] For ease of control, the sliding hydraulic cylinder 3 is connected to the sliding directional valve, the tilting hydraulic cylinder 6 is connected to the tilting directional valve, and the lifting hydraulic cylinder 7 is connected to the lifting directional valve. The sliding directional valve, the tilting directional valve, and the lifting directional valve are electrically connected to the controller, which is a 32-bit microcontroller.

[0040] like Figure 2 As shown, in order to extend the stroke of the sliding hydraulic cylinder 3, the sliding hydraulic cylinder 3 is a multi-stage hydraulic cylinder.

[0041] Working process: When transporting material 14, the robot first moves to the material 14, then the sliding hydraulic cylinder 3 shortens, which causes the back plate 4 to extend outside the walking chassis 1. The extension of the back plate 4 can drive the telescopic rod 5 to shorten, then the tilting hydraulic cylinder 6 extends, which in turn drives the telescopic rod 5 to rotate, which in turn drives the back plate 4 to move, so that the part of the back plate 4 that extends outside the walking chassis 1 lands on the ground.

[0042] The operator then fixes the material 14 to the free end of the chain 13. The lifting hydraulic cylinder 7 then extends, which in turn drives the wheel frame 8 to rise, which in turn drives pulley A 10 and pulley C 12 to rise, which in turn drives the free end of the chain 13 to move in the direction of the lifting hydraulic cylinder 7, which in turn drives the material 14 to move towards the back plate 4 until the material 14 moves onto the back plate 4.

[0043] After material 14 is moved onto back plate 4, the staff fixes material 14 onto back plate 4. Then, tilting hydraulic cylinder 6 shortens, which in turn drives telescopic rod 5 to rotate in the opposite direction, which in turn drives back plate 4 to move in the opposite direction, so that back plate 4 returns to the chassis 1. Then, sliding hydraulic cylinder 3 extends, which in turn causes back plate 4 to retract completely back onto chassis 1.

[0044] After the backplate 4 is fully retracted onto the walking chassis 1, the lifting hydraulic cylinder 7 shortens, and the robot moves the material 14 to the destination.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
