Problems solved by technology

[0002] In order to facilitate the long-distance transmission of electric energy, the transmission network has spread over most areas of the motherland. In order to ensure the normal operation of the transmission line, it is necessary to send personnel to maintain it regularly. In these areas, there are many harsh environments such as mountain roads, swamps, jungles, and river beaches. This has brought great inconvenience to the inspection and maintenance of personnel. The traditional method is that personnel rely on walking to carry out inspections. Without vehicles, supplies and maintenance equipment cannot be carried. Therefore, the inspection of the line has brought great labor intensity to the staff and has brought great inconvenience to the maintenance of the inspection line. The method currently adopted is mainly to improve the electric inspection vehicle, such as Increase the bottom armor to enhance the power inspection vehicle to resist the danger of scratching the chassis on mountain roads, and modify the wide-body tires to improve off-road capability, but when encountering muddy areas such as swamps and river beaches, the passability of the electric inspection vehicle will be greatly reduced. Once the wheels of the vehicle are damaged If there is a trap, the vehicle will be difficult to move, which will affect the normal inspection work

specific Embodiment 1

[0027] Specific embodiment 1, such as Figure 1 to Figure 5 As shown, the present invention is a kind of electric power inspection vehicle for harsh road conditions, including a car body and wheels that drive the car body to move, and the wheels include a wheel hub 1 and a tread 2 arranged on the wheel hub 1, and the wheel hub 1 The center of rotation is provided with a hub 3, the hub 3 is connected to the hub 1 by means of the spoke 4, and the hub 1 is connected to the drive shaft 5 on the vehicle body by means of the hub 3, and the tread 2 is in the shape of a split arc structure, the hub 1 is provided with a telescopic structure, and the tread 2 has a degree of freedom of expansion and contraction along the axial direction of the hub 1 by means of the telescopic structure. The telescopic block 7 in the telescopic groove 6, the tread 2 is fixedly connected with the telescopic block 7, and the telescopic structure also includes a driving structure arranged in the hub 1. The ...

specific Embodiment 2

[0031] Specific embodiment 2, further, such as figure 1 and image 3 As shown, the drive structure includes a drive screw 11 connected to a motor 10 for power, a drive disc 12 sleeved on the sleeve 3 and slidably connected with the sleeve 3, and the drive disc 12 is driven by the rotation of the drive screw 11 A degree of translational freedom for reciprocating movement along the axial direction of the shaft sleeve 3 is formed. The driving disc 12 is provided with a driving slide 13, and the driving slide 13 is drivingly connected with the tread 2 by means of a transmission link structure. The drive screw 11 is provided with a transmission thread and forms a transmission connection with the drive disk 12 by means of the transmission thread. The lead angle of the transmission thread is less than 30°, so that the drive screw 11 and the drive disk 12 form a self-locking fit, avoiding the drive screw 11 from stopping. The situation that drive disc 12 reverses takes place after tu...

specific Embodiment 3

[0039] Specific embodiment 3, such as Figure 4 As shown, in order to further increase the passability of the wheel of the present invention, the telescopic structure is arranged in two groups interlaced with each other along the forward and reverse directions of the hub 1 axis. A group of counter drive discs 121 opposite to the drive disc 12 are added. The drive disc 12 and the counter drive disc 121 are installed on the axle sleeve 3 respectively, and are driven by the drive screw 11 respectively. There are anti-rotating threads between them, so as to ensure that the driving disc 12 and the counter-driving disc 121 move inward or outward at the same time. The structure is the same, but the two are reversed, so as to improve the interchangeability of the two and reduce the manufacturing cost.

[0040] The drive disc 12 has a relatively large diameter, and heat dissipation holes are arranged on the disc surface along its rim portion. The drive disc 12 is used as a brake disc ...

Abstract

The invention relates to an electric inspection vehicle for bad road conditions, and belongs to the field of electric inspection vehicles. On the basis of the electric inspection vehicle, vehicle wheels are improved, when muddy road conditions occur, particularly, when tires stick in mud pits and cannot grasp the ground, with the assistance of stretching of tire faces, the contact area of the vehicle wheels and the ground is increased, irregular surface shapes of the vehicle wheels are formed, the adhesive capability to the ground is improved, good trafficability of the vehicle is guaranteed,and thus smooth proceeding of inspection work is guaranteed.
