The patrol robot does not need to install a steering motor and a drive motor on each wheel as in the prior art, so it has the advantages of simple structure, simple process, small size, high assembly efficiency, power saving, low cost and good stability.

[0004] However, the existing inspection robots still have the following problems:

[0005] When performing inspection tasks, inspection robots often go to areas that require climbing. In order to expand their inspection range, inspection robots usually install cameras and other components higher. This makes it easy for the center of gravity to shift when climbing, which can cause the inspection robot to fall over. This not only affects the subsequent execution of tasks, but may also cause damage to the inspection robot and result in property loss. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an anti-dumping device for an inspection robot. When the user is inspecting the robot body, if the robot body needs to climb a slope, the auxiliary wheels can be pushed down by an electric telescopic rod to keep the robot body in a horizontal state at all times, thereby avoiding dumping.

[0007] The utility model provides the following technical solutions: an anti-dumping device for an inspection robot, comprising a robot body and four movable wheels installed on the robot body, the front and rear ends of the robot body are connected to electric telescopic rods, the output ends of the two electric telescopic rods are connected to transmission mechanisms, the two sides of the two transmission mechanisms are connected to auxiliary wheels, the bottom surface of the robot body is fixedly connected to an electronic level, and the electronic level is located at the center of the four movable wheels.

[0008] Furthermore, the transmission mechanism includes a double-headed motor and two connecting rods. The outer wall of the double-headed motor is fixedly connected to the output end of the electric telescopic rod. The two output shafts of the double-headed motor are respectively fixedly connected to the adjacent ends of the two connecting rods. The ends of the two connecting rods that are away from each other are respectively fixedly connected to the two auxiliary wheels.

[0009] Furthermore, a protective shell is sleeved on and fixedly connected to the outer wall of the double-headed motor. The protective shell is sleeved on the outer wall of the output end of the electric telescopic rod and is rotatably connected to the output end of the electric telescopic rod.

[0010] Furthermore, protective covers are fixedly connected to both ends of the robot body near the two electric telescopic rods, and recovery cavities are opened on the bottom surfaces of the two protective covers. The two electric telescopic rods and the two transmission mechanisms are respectively located inside the two recovery cavities, and the outer wall of the electric telescopic rod is fixedly connected to the top surface of the inner wall of the recovery cavity.

[0011] Furthermore, the inner wall of the recovery chamber is fixedly connected to a support plate, and a number of auxiliary rods are penetrated and slidably connected to the inner wall of the support plate. The lower ends of the auxiliary rods are fixedly connected to rings, and the rings are respectively mounted on the outer walls of the two connecting rods and rotatably connected to the outer walls of the connecting rods.

[0012] Furthermore, the number of the auxiliary rods and the rings is even, and they are respectively located on both sides of the electric telescopic rod.

[0013] Furthermore, the two protective covers are fixedly connected to an anti-collision frame on one side away from each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The anti-dumping device of the inspection robot is achieved by adding two electric telescopic rods at both ends of the robot body, and connecting the transmission mechanism and the two auxiliary wheels through the electric telescopic rods. When the user is inspecting the robot body, if the robot body needs to climb a slope, the electric telescopic rods can be used to push the auxiliary wheels down, so that the robot body always remains in a horizontal state, thereby avoiding dumping.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4 , an anti-dumping device for an inspection robot, comprising a robot body 1 and four moving wheels 2 installed on the robot body 1, electric telescopic rods 10 are connected to the front and rear ends of the robot body 1, the output ends of the two electric telescopic rods 10 are connected to transmission mechanisms, auxiliary wheels 4 are connected to the two sides of the two transmission mechanisms, and an electronic level 13 is fixedly connected to the bottom surface of the robot body 1, and the electronic level 13 is located at the center of the four moving wheels 2.

[0023] The anti-dumping device of the inspection robot in the utility model is similar to the structure of the existing inspection robot, such as the inspection robot model: LDARM-XJ-A01. Figures 1 to 4As shown, when the anti-dumping device of the inspection robot in the utility model is used, the robot body 1 is first placed in a suitable position, and then the robot body 1 is controlled to move by a remote controller, so that the route that needs to be inspected can be inspected. If there is a slope that needs to be climbed up or moved down during the movement, when the two moving wheels 2 in front of the robot body 1 step on the slope, the entire robot body 1 will have a certain inclination. At the same time, the electronic level 13 will transmit an electrical signal to the external processor, and then the external processor will automatically open the corresponding electric telescopic rod 10, so that the two transmission mechanisms and the auxiliary wheels 4 at the front or rear end of the robot body 1 can be controlled to extend downward until the auxiliary wheels 4 exceed After the moving wheel 2, until the electronic level 13 on the bottom surface of the robot body 1 is in a horizontal state, the robot body 1 will also be in a horizontal state at this time, thereby avoiding tipping over. After the auxiliary wheel 4 falls to the ground and is subjected to force, the external controller starts the transmission mechanism, which provides power to the auxiliary wheel 4 to facilitate the movement of the auxiliary wheel 4. It should be noted here that the above-mentioned electronic level 13 is a prior art and is not described in detail. In addition, when the robot body 1 is undergoing an inclination test, it can withstand a certain inclination and will not tip over within the inclination range. The initial value of the electronic level 13 can be set to this standard. When the inclination is not greater than this inclination, the electric telescopic rod 10 will not be started, and no specific limitation is made.

[0024] Please refer to Figure 4 The transmission mechanism includes a double-headed motor 12 and two connecting rods 8. The outer wall of the double-headed motor 12 is fixedly connected to the output end of the electric telescopic rod 10. The two output shafts of the double-headed motor 12 are respectively fixedly connected to the adjacent ends of the two connecting rods 8. The ends of the two connecting rods 8 that are away from each other are respectively fixedly connected to the two auxiliary wheels 4. When the external controller turns on the switch of the double-headed motor 12, the two output ends of the double-headed motor 12 rotate at the same time, and drive the two connecting rods 8 to rotate at the same time, and provide power to the two auxiliary wheels 4 after the connecting rods 8 rotate, so that the two auxiliary wheels 4 can walk conveniently.

[0025] Please refer to Figure 2-Figure 4 The outer wall of the double-headed motor 12 is sleeved and fixedly connected with a protective shell 7, which is sleeved on the outer wall of the output end of the electric telescopic rod 10 and is rotatably connected to the output end of the electric telescopic rod 10. By providing the protective shell 7, water, dust, stones and other objects on the ground can be prevented from causing damage to the double-headed motor 12.

[0026] Please refer to Figure 1-Figure 4The robot body 1 is fixedly connected with protective covers 3 at both ends near the two electric telescopic rods 10. The bottom surfaces of the two protective covers 3 are provided with recovery chambers 301. The two electric telescopic rods 10 and the two transmission mechanisms are respectively located inside the two recovery chambers 301. The outer wall of the electric telescopic rod 10 is fixedly connected to the top surface of the inner wall of the recovery chamber 301. By providing the protective cover 3 and opening the recovery chamber 301 inside the protective cover 3, firstly, the electric telescopic rod 10 can be protected to prevent it from being hit or smashed by external objects during the inspection process; secondly, when the auxiliary wheels 4 are not in use, the two auxiliary wheels 4 and the transmission mechanism can be stored therein to avoid occupying external space.

[0027] Please refer to Figure 3 and Figure 4 The inner wall of the recovery chamber 301 is fixedly connected with a support plate 6, and a plurality of auxiliary rods 11 are penetrated and slidably connected with the inner wall of the support plate 6, and the lower ends of the plurality of auxiliary rods 11 are fixedly connected with collars 9, and the plurality of collars 9 are respectively sleeved on the outer walls of the two connecting rods 8 and are rotatably connected with the outer walls of the connecting rods 8. By providing the support plate 6, the auxiliary rod 11 and the collars 9, firstly, a supporting force can be given to the two connecting rods 8 through the collars 9 to prevent the connecting rods 8 from bending downward or upward; secondly, when the electric telescopic rod 10 pushes the transmission mechanism and the two auxiliary wheels 4 to rise and fall, there is an auxiliary force to prevent idling or tilting.

[0028] Please refer to Figure 3 and Figure 4 The number of auxiliary rods 11 and collars 9 is even, and they are respectively located on both sides of the electric telescopic rod 10. Setting it to an even number can make the force more uniform.

[0029] Please refer to Figure 1-Figure 4 The two protective covers 3 are fixedly connected to the side away from each other with an anti-collision frame 5. By setting the anti-collision frame 5, it is possible to prevent the robot body 1 from colliding with some hard objects such as walls and stone piers during movement, thereby causing the protective cover 3 to deform.
