[0004] The disadvantage of the above-mentioned disclosed solution is that when placing the equipment to be transported on the pallet, it is necessary to first turn open the turning bar, place it on the pallet, then close the turning bar, and fix the turning bar with a pin, and finally adjust the distance between the top plate and the pallet, which results in complicated operation steps, low degree of automation, and reduced efficiency of transporting equipment. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a transport robot that can adapt to road conditions. The pressure plate moves vertically while driving the railing to rotate, which saves operating steps and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transport robot that can adapt to road conditions, including a vehicle body, an installation cavity is provided in the vehicle body, a placement plate is slidingly provided in the installation cavity, and a shock-absorbing component for reducing the shock of the placement plate is provided in the installation cavity; a hollow shaft is symmetrically rotated on one side of the top of the placement plate, a railing is fixedly provided on the hollow shaft, a sliding rod is sleeved in the hollow shaft, a sliding groove is provided on the hollow shaft, a sliding block is fixedly provided on the sliding rod, the sliding block is slidably connected to the sliding groove, a pressure plate is fixedly provided on the sliding rod, a driving device is provided on the placement plate, the driving device drives the pressure plate to move vertically, the pressure plate drives the sliding rod to move vertically, the sliding rod drives the sliding block to slide along the sliding groove, thereby driving the hollow shaft to rotate, and the hollow shaft drives the railing to rotate.

[0007] Furthermore, the shock absorbing assembly includes a hydraulic cylinder, which is fixedly arranged at the bottom of the installation cavity of the vehicle body. A piston rod is slidably arranged on the hydraulic cylinder, the top of the piston rod is connected to the placement plate, and a spring is sleeved on the piston rod. The two ends of the spring are respectively connected to the placement plate and the hydraulic cylinder.

[0008] Furthermore, the bottom end of the piston rod extends into the hydraulic cylinder and is fixedly provided with a piston plate, the piston plate is slidably connected to the hydraulic cylinder, a flow hole is opened on the piston plate, and hydraulic oil is provided between the piston plate and the hydraulic cylinder.

[0009] Furthermore, the driving device includes an electric telescopic rod, which is arranged on the placement plate, and the output end of the electric telescopic rod is fixedly connected to the pressing plate.

[0010] Furthermore, two symmetrically arranged telescopic rods are fixedly provided on one side of the placement plate away from the hollow shaft, and the two telescopic rods are fixedly connected to the pressing plate.

[0011] Furthermore, a connecting rod is fixedly arranged between the two telescopic rods, an L-shaped fixing rod is symmetrically fixedly arranged on the placement plate, the L-shaped fixing rod is fixedly connected to the telescopic rod, and the electric telescopic rod is fixedly arranged on the L-shaped fixing rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Because the sliding block is slidably connected to the sliding groove, a pressure plate is fixedly mounted on the sliding rod, and a drive device is provided on the placement plate, which drives the pressure plate to move vertically. Therefore, when placing an item on the placement plate, the electric telescopic rod pushes the pressure plate upward, which in turn drives the sliding rod upward, which in turn drives the sliding block to slide within the sliding groove, thereby rotating the hollow shaft, which in turn drives the railing to open outward from the vehicle body. The item to be transported is then placed on the placement plate, and the electric telescopic rod retracts, which in turn drives the pressure plate downward, which in turn drives the sliding rod downward, which in turn drives the sliding block downward. The sliding block moves along the sliding groove, causing the hollow shaft and railing to rotate and reset. The pressure plate then continues to move downward until it contacts the top surface of the item, securing the item. This allows the pressure plate to simultaneously open or close the railing during its vertical movement, thereby saving operational steps, achieving a high degree of automation, and improving the efficiency of item handling.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-4 The utility model provides a technical solution: a transport robot that can adapt to road conditions, including a vehicle body 1, a roller 2 is provided at the bottom of the vehicle body 1, and the vehicle body 1 can be moved by the roller 2. An installation cavity is provided in the vehicle body 1, a placement plate 6 is slidingly provided in the installation cavity, and a shock-absorbing component for reducing the shock of the placement plate 6 is provided in the installation cavity. The shock-absorbing component includes two hydraulic cylinders 3, and the two hydraulic cylinders 3 are fixedly provided at the bottom of the installation cavity of the vehicle body 1, and the two hydraulic cylinders 3 are symmetrically arranged. A piston rod 4 is slidingly provided in the hydraulic cylinder 3, and a fixed plate is fixedly provided on the top of the piston rod 4, and the fixed plate is fixedly connected to the placement plate 6. A spring 5 is sleeved on the piston rod 4, and the two ends of the spring 5 are fixedly connected to the fixed plate and the hydraulic cylinder 3 respectively.

[0021] The piston rod 4 is sealed and slidably connected to the hydraulic cylinder 3. The bottom end of the piston rod 4 extends into the hydraulic cylinder 3 and is fixedly provided with a piston plate. The piston plate is sealed and slidably connected to the hydraulic cylinder 3. Flow holes 18 are symmetrically opened on the piston plate. Hydraulic oil is provided between the piston plate and the hydraulic cylinder 3.

[0022] A hollow shaft 12 is symmetrically mounted on one side of the top of the placement plate 6. A sliding rod 15 slides within the hollow shaft 12, and a pressure plate 17 is fixedly mounted on the top of the sliding rod 15. Two symmetrically arranged telescopic rods 10 are fixedly mounted on the side of the placement plate 6 away from the hollow shaft 12. Both telescopic rods 10 are fixedly connected to the pressure plate 17. This improves the stability of the pressure plate 17 during vertical movement. The telescopic rods 10 include a sleeve, which is fixedly connected to the placement plate 6. A sleeve rod slides within the sleeve, and the top of the sleeve rod is fixedly connected to the pressure plate 17.

[0023] A connecting rod 11 is fixed between the sleeves of the two telescopic rods 10. L-shaped fixing rods 7 are symmetrically fixed to the top of the placement plate 6. The L-shaped fixing rods 7 are located between the corresponding hollow shafts 12 and the telescopic rods 10 and are fixedly connected to the sleeves of the telescopic rods 10. Railings 16 are fixed to the outer periphery of the hollow shafts 12. The railings 16, L-shaped fixing rods 7, and connecting rods 11 provide protection for transported items, preventing them from falling off the placement plate 6.

[0024] A sliding groove 14 is formed on the hollow shaft 12, and a sliding block 13 is fixedly mounted on the sliding rod 15. The sliding block 13 is slidably connected to the sliding groove 14. A driving device is provided on the placement plate 6. The driving device drives the pressure plate 17 to move vertically, and the pressure plate 17 drives the sliding rod 15 to move vertically. The sliding rod 15 drives the sliding block 13 to slide along the sliding groove 14, thereby driving the hollow shaft 12 to rotate. The hollow shaft 12 drives the railing 16 to rotate.

[0025] The driving device includes an electric telescopic rod 9 , which is arranged on the placement plate 6 , and an output end of the electric telescopic rod 9 is fixedly connected to the pressing plate 17 .

[0026] A fixing block 8 is fixedly provided on the L-shaped fixing rod 7, and the electric telescopic rod 9 is fixedly provided on the fixing block 8. The motion stroke of the output end of the electric telescopic rod 9 can be reduced.

[0027] The working principle of the transport robot that can adapt to road conditions provided by the utility model is as follows:

[0028] During use, the electric telescopic rod 9 is activated to extend, pushing the pressure plate 17 upward, which in turn causes the telescopic rod 10 to extend. Simultaneously, the pressure plate 17 drives the sliding rod 15 upward, which in turn causes the sliding block 13 to slide within the sliding groove 14. When the sliding block 13 reaches the spiral groove of the sliding groove 14, as the electric telescopic rod 9 continues to extend, the sliding block 13 slides within the spiral groove of the sliding groove 14, causing the hollow shaft 12 to rotate. The hollow shaft 12 drives the handrail 16 to rotate 90 degrees toward the outside of the vehicle body 1, opening it to facilitate the placement of items on the placement plate 6. The electric telescopic rod 9 is then deactivated.

[0029] The object to be transported is then placed on the placement plate 6, and the electric telescopic rod 9 is activated to retract. This drives the pressing plate 17 downward, which in turn drives the sliding rod 15 downward. The sliding rod 15 then drives the sliding block 13 downward. The sliding block 13 moves along the sliding groove 14, causing the hollow shaft 12 and the railing 16 to rotate and reset. The pressing plate 17 then continues to move downward. When the pressing plate 17 contacts the top surface of the object, the electric telescopic rod 9 stops retracting, thereby securing the object.

[0030] Then the vehicle body 1 is moved by the rollers 2 , and the vehicle body 1 drives the articles to move to the designated location via the placement plate 6 .

[0031] When roller 2 passes over a bumpy road, the items on placement plate 6 vibrate, causing placement plate 6 to move up and down, driving piston rod 4 up and down. This movement of piston rod 4 initially mitigates the vibration amplitude via spring 5. Simultaneously, piston rod 4 drives the piston plate up and down within hydraulic cylinder 3. The hydraulic oil in hydraulic cylinder 3 repeatedly flows through flow holes 18 to the upper and lower sides of the piston plate, providing secondary shock absorption for piston rod 4, effectively mitigating its vibration amplitude, thereby reducing vibration generated by the items being transported and preventing damage.

[0032] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
