Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering detection robots, in particular to a shock-absorbing wheel for a construction engineering detection robot. Background Art

[0002] Before the construction of a building project begins, workers need to conduct sufficient geological exploration operations on the designated construction site. Engineering geological survey is a geological investigation and research work conducted to identify the geological factors that affect engineering buildings. The geological factors that need to be surveyed include geological structure or geological structure: landform, hydrogeological conditions, physical and mechanical properties of soil and rock, natural (physical) geological phenomena and natural building materials, etc., which require the use of measuring instruments.

[0003] Common construction engineering inspection robots only include wheel structures, which can ensure the normal movement of the robot, but lack a shock-absorbing structure and cannot ensure that the robot remains stable while moving. The robot is prone to bumping while moving, causing the measurement position to shift, affecting the measurement accuracy.

[0004] Therefore, the problem that the above-mentioned construction engineering inspection robot lacks a shock-absorbing structure and cannot ensure that the robot remains stable when moving needs to be solved urgently to improve the use scenarios of the construction engineering inspection robot. Utility Model Content

[0005] In order to overcome the problem that common construction engineering inspection robots lack a shock-absorbing structure and cannot ensure that the robot remains stable when moving, the robot is prone to bumps when moving, causing the measurement position to shift, affecting the measurement accuracy.

[0006] The technical solution of the utility model is: a shock-absorbing wheel for a construction engineering inspection robot, including a universal assembly, the universal assembly is composed of a connecting plate, a connecting hole, a universal shaft, a wheel frame, a wheel body, an anti-skid groove and a wheel shaft, four connecting holes are opened in a rectangular shape at the four corners of the top of the connecting plate, a shock-absorbing assembly is arranged above the universal assembly, the shock-absorbing assembly is composed of a support plate, a support rod, a shock-absorbing spring, a pressure pipe, a floating piston, hydraulic oil, a pressure rod, a working piston, a fixed plate and a fixed hole, and a support plate is arranged above the connecting plate.

[0007] Preferably, by setting up a shock-absorbing structure, it is possible to ensure that the robot remains stable when moving, so as to solve the problem that common construction engineering inspection robots only include a wheel structure, which can ensure the normal movement of the robot but lack a shock-absorbing structure and cannot ensure that the robot remains stable when moving. The robot is prone to bumps when moving, causing the measurement position to shift, thereby affecting the measurement accuracy.

[0008] Preferably, a universal shaft is provided in the middle of the bottom of the connecting plate, and a wheel frame is welded to the bottom end of the universal shaft. When the detection robot turns, the moving direction of the wheel body is changed by rotating the universal shaft.

[0009] Preferably, a wheel axle is provided on the inner side of the wheel frame, a wheel body is mounted on the wheel axle, and anti-skid grooves are provided at equal intervals around the wheel body. When the detection robot needs to move, the wheel body can rotate by rotating the wheel axle, and the rotating wheel body can drive the detection robot to move.

[0010] Preferably, four support rods are welded in a rectangular shape at the four corners of the bottom of the support plate corresponding to the connection holes, and the bottom ends of the support rods are inserted into the internal welding of the connection holes. The support plate separates the connecting plate and the support plate to prevent the connecting plate and the support plate from affecting the rotation of the universal shaft after being fitted together.

[0011] Preferably, a shock-absorbing spring is welded on the top of the support plate, and a pressure tube is welded on the top of the support plate at the position corresponding to the shock-absorbing spring. A pressure rod is arranged on the top of the pressure tube, and the bottom end of the pressure rod is inserted into the interior of the pressure tube. When the detection robot is bumped during movement, the shock-absorbing spring is used to buffer the pressure.

[0012] Preferably, a floating piston is placed at the bottom end of the pressure tube, hydraulic oil is arranged inside the pressure tube, and a number of working pistons are arranged at equal intervals at the bottom end of the pressure rod. The pressure generated by the bumps is transmitted to the pressure rod, so that the pressure rod drives the working piston to press down, and the working piston squeezes the hydraulic oil inside the pressure tube. The hydraulic oil is squeezed from the gap between the floating piston and the inner wall of the pressure tube into the cavity below the floating piston. When the hydraulic oil in the cavity increases, the resistance of the floating piston increases, and a reaction force is given to the floating piston to reset the hydraulic oil, thereby further buffering the pressure and realizing the shock absorption function, thereby preventing the robot from bumping while moving, causing the measurement position to shift, thereby affecting the measurement accuracy.

[0013] Preferably, a fixing plate is provided at the top of the shock-absorbing spring, and the top of the fixing plate is rectangular and has a number of fixing holes. The top of the shock-absorbing spring and the top of the pressure rod are welded to the bottom of the fixing plate. When the wheel is installed, the fixing plate is fitted with the bottom of the detection robot, and the fixing plate is then fixed to the detection robot after bolts pass through the fixing holes.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a shock-absorbing structure, the robot can be kept stable when moving, so as to solve the problem that common construction engineering inspection robots only include wheel structures, which can ensure the normal movement of the robot, but lack shock-absorbing structures, and cannot ensure that the robot remains stable when moving. It is easy for the robot to be bumpy when moving, resulting in measurement position deviation, affecting the measurement accuracy;

[0016] 2. When the detection robot is bumped during movement, the shock-absorbing spring buffers the pressure received. The pressure generated by the bump is transmitted to the pressure rod, so that the pressure rod drives the working piston to press down. The working piston squeezes the hydraulic oil inside the pressure tube. The hydraulic oil is squeezed from the gap between the floating piston and the inner wall of the pressure tube into the cavity below the floating piston. When the hydraulic oil in the cavity increases, the resistance of the floating piston increases, and a reaction force is given to the floating piston to reset the hydraulic oil, thereby further buffering the pressure and realizing the shock-absorbing function.

[0023] See also Figure 1-4A shock-absorbing wheel for a construction engineering inspection robot includes a universal assembly 1, which consists of a connecting plate 11, a connecting hole 12, a universal shaft 13, a wheel frame 14, a wheel body 15, an anti-skid groove 16 and a wheel shaft 17. Four connecting holes 12 are provided in a rectangular shape at the four corners of the top of the connecting plate 11. A shock-absorbing assembly 2 is arranged above the universal assembly 1.

A support plate 21 is arranged above the connecting plate 11.

[0024] See also Figure 1-4 In this embodiment, a universal shaft 13 is provided in the middle of the bottom of the connecting plate 11, and a wheel frame 14 is welded to the bottom end of the universal shaft 13. When the detection robot is bumped during movement, the pressure received is buffered by the shock-absorbing spring 23, and the pressure generated by the bump is transmitted to the pressure rod 25, so that the pressure rod 25 drives the working piston 251 to press down, and the working piston 251 squeezes the hydraulic oil 242 inside the pressure tube 24, and the hydraulic oil 242 is squeezed from the gap between the floating piston 241 and the inner wall of the pressure tube 24 into the cavity below the floating piston 241. When the hydraulic oil 242 in the cavity increases, the resistance of the floating piston 241 will increase, and a reaction force will be given to the floating piston 241 to reset the hydraulic oil 242, thereby further buffering the pressure and completing the shock absorption work.

[0025] See also Figure 1-4 A shock absorbing spring 23 is welded on the top of the support plate 21, and a pressure tube 24 is welded on the top of the support plate 21 at the position corresponding to the shock absorbing spring 23. A pressure rod 25 is arranged on the top of the pressure tube 24, and the bottom end of the pressure rod 25 is inserted into the interior of the pressure tube 24. A floating piston 241 is placed on the bottom end of the pressure tube 24. Hydraulic oil 242 is arranged inside the pressure tube 24. A plurality of working pistons 251 are arranged at equal intervals on the bottom end of the pressure rod 25. When the detection robot is bumped during movement, the shock absorbing spring 23 is used to buffer the pressure received, and the pressure generated by the bump is transmitted to the pressure rod 25, so that the pressure rod 25 drives the working piston 251 to press downward, and the working piston 251 squeezes the hydraulic oil 242 inside the pressure tube 24. The hydraulic oil 242 is squeezed from the gap between the floating piston 241 and the inner wall of the pressure tube 24 into the cavity below the floating piston 241. When the hydraulic oil 242 in the cavity increases, the resistance of the floating piston 241 increases, and a reaction force is given to the floating piston 241 to reset the hydraulic oil 242, thereby further buffering the pressure and realizing the shock absorption function, thereby preventing the robot from being jolted during movement, resulting in measurement position deviation and affecting the measurement accuracy.

[0026] When working, the fixing plate 26 is fitted with the bottom of the detection robot, and the fixing plate 26 is fixed to the detection robot after passing through the fixing hole 27 by bolts. When the detection robot needs to move, the wheel body 15 can be rotated by rotating the wheel shaft 17, and the rotating wheel body 15 can drive the detection robot to move. When the detection robot turns, the direction of travel of the wheel body 15 is changed by rotating the universal shaft 13. When the detection robot is bumped during movement, the shock-absorbing spring 23 buffers the pressure generated by the bump The pressure is transmitted to the pressure rod 25, so that the pressure rod 25 drives the working piston 251 to press downward, and the working piston 251 squeezes the hydraulic oil 242 inside the pressure tube 24. The hydraulic oil 242 is squeezed from the gap between the floating piston 241 and the inner wall of the pressure tube 24 into the cavity below the floating piston 241. When the hydraulic oil 242 in the cavity increases, the resistance of the floating piston 241 increases, and a reaction force is given to the floating piston 241 to reset the hydraulic oil 242, thereby further buffering the pressure and achieving the shock absorption function.

[0027] Through the above steps, by setting up a shock-absorbing structure, it is possible to ensure that the robot remains stable when moving, so as to solve the problem that common construction engineering inspection robots only include a wheel structure, which can ensure the normal movement of the robot, but lack a shock-absorbing structure and cannot ensure that the robot remains stable when moving. The robot is prone to bumps when moving, causing the measurement position to shift, affecting the measurement accuracy.
