Embodiment 1

[0027] refer to Figure 1a and Figure 1b , a climbing robot car, comprising a car body 2, the front and rear ends of the car body 2 are installed with wheels 2, the end face of the car body 2 facing the wall 3 is connected and fixed with an adsorption mechanism, the adsorption mechanism includes a body, and the The body is a hollow cylinder 4, a cover plate 5 is arranged above the hollow cylinder 4, the upper end surface of the cover plate 5 is connected and fixed with the vehicle body 2, and the lower end surface of the cover plate 5 is connected with the vehicle body 2. The upper end surface of the hollow cylinder 4 is closed and connected; the inner wall surface of the hollow cylinder 4 is provided with a tangential nozzle 41; there is a gap between the lower end surface of the hollow cylinder 4 and the wall surface 1, and the The gap forms the first exhaust flow channel 42 between the outer edge of the lower end surface of the hollow cylinder 4 and the wall surface 1, and...

Embodiment 2

[0033] refer to Figure 2a and 2b , on the basis of the above-mentioned embodiment 1, a motor 6 is installed on the upper end surface of the vehicle body 2, and the motor 6 is connected to the cover plate 5 through a screw 61 driven by it; the screw 61 is connected to the The cover plate 5 is threaded; the cover plate 5 and the hollow cylinder 4 are provided with a pressure measuring hole, and the pressure measuring hole is connected with the pressure sensor 7 . The car body 2 is provided with a guide hole, and a guide post 8 is arranged in the guide hole, and one end of the guide post 8 passes through the guide hole and is fixedly connected to the upper surface of the cover plate 5 , the guide column 8 can slide in the guide hole.

[0034] The greater the pressure on the car body, the greater the contact force between the wheels and the wall, and the greater the friction on the wheels from the wall. Therefore, how to increase the pressure on the car body is a key point in t...

Embodiment 3

[0039] refer to Figure 3a , on the basis of the above-mentioned embodiment 1, an annular partition 9 is provided below the hollow cylinder 4, and the upper end surface of the annular partition 9 passes through the pad 10 and the outer edge of the lower end surface of the hollow cylinder 4 fixed connection; the first exhaust flow channel is formed between the lower end surface of the annular partition 9 and the wall; the spacer 10 covers part of the area of ​​the annular partition 9, and the space between the spacer and the spacer The distance between them forms a second exhaust flow channel between the outer edge of the lower end surface of the hollow cylinder and the annular partition, and the second exhaust flow channel communicates with the inner and outer peripheral environments of the hollow cylinder. A soft gasket 11 is provided on the outer edge of the lower end surface of the annular partition 9 . The soft pad 11 is made of soft material, one end of the soft material...

Abstract

The invention discloses a climbing mechanism vehicle. The climbing mechanism vehicle comprises a vehicle body; wheels are mounted at the front end and the rear end of the vehicle body; the end surface of the vehicle body, facing the wall surface is fixedly connected with an absorbing mechanism; the absorbing mechanism comprises a mechanism body which is a circular hollow barrel; a cover plate is arranged above the circular hollow barrel; the upper end surface of the cover plate is fixedly connected with the vehicle body; the lower end surface of the cover plate is in closed connection with the upper end surface of the circular hollow barrel; a tangential nozzle is formed in the inner wall surface of the circular hollow barrel; a gap is formed between the lower end surface of the circular hollow barrel and the wall surface; a first exhaust channel is formed between the outer edge of the lower end surface for forming the gap, of the circular hollow barrel and the wall surface; the first exhaust channel is communicated with the inside and peripheral environments of the circular hollow barrel. The climbing mechanism vehicle can be attached to various wall surfaces, so that the absorbing capacity is high, and the applicable scope is wide.

Description

technical field [0001] The invention relates to a climbing robot vehicle. Background technique [0002] The climbing robot car is a car body that can walk on vertical walls and ceilings, and plays an important role in many specific occasions. For example, we install an ultrasonic flaw detector on the car body, and the climbing robot car can replace people to carry out flaw detection and inspection of large buildings (bridges, culverts, etc.), which greatly reduces operating costs and shortens working hours. [0003] In order for the climbing robot car to cling to the wall, we need to apply a pressure on the car body that points to the wall. When the climbing robot car is attached to the vertical wall, the compressive force will generate friction between the car body and the wall. The friction force not only overcomes the gravity of the car body itself but also provides the driving force required for the movement of the car body; In the case of the patio wall, part of the c...
