Embodiment Construction

[0032] The present invention provides a one-armed wheeled motion mechanism of a tunnel cable inspection robot. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0033] figure 1 It is a schematic diagram of the motion mechanism and track including the tunnel cable inspection robot, in which the one-armed wheel mechanism and the motor part constitute the head part of the robot, and the wheels are clamped between the upper track 1 and the lower track 2 for movement. The main body part is connected by groove type connecting arm 8.

[0034] Figure 2 is the front view and cross-sectional view of the track: due to the limited weight of the robot, light aluminum profiles are used as the material of the guide rail, which reduces the burden of installation and transportation while ensuring the mechanical strength. Considering the smooth operation of the robot, the gap left by the wheel 5 after sink...

Abstract

The invention belongs to the field of a rail wheel type structure and particularly relates to an independent arm wheel type movement mechanism of a tunnel cable inspection robot. The movement mechanism is divided into two parts including an independent arm wheel type inspection robot and a rail, the rail is divided into an upper rail and a lower rail, the middle of each surface of the rail is respectively provided with a V-shaped groove, and the cross section of the V-shaped groove is respectively in an X shape. The independent arm wheel type inspection robot is structurally characterized in that a wheel shaft of a wheel are connected with a motor through a shaft coupling, a ladder-shaped protecting frame is arranged outside the shaft coupling, the lower end of the ladder-shaped protecting frame is connected with a groove-shaped connecting arm , the lower end of the groove-shaped connecting arm is connected with the inspection robot, and one side of the groove-shaped connecting arm near the wheel is provided with a charger. Two sides of the wheel are respectively provided with inner rubber sleeve wheels connected through screws, and outer rings of the inner rubber sleeve wheels are provided with outer rubber sleeve wheels. The independent arm wheel type movement mechanism has the advantages that the structure is simple, the space is saved, and the independent arm wheel type movement mechanism can be used for the tunnel cable inspection robot and can also be applied to all single wheel motor vehicles and equipment running on the rail.

Description

technical field [0001] The invention belongs to the field of rail wheel structures, and in particular relates to a single-arm wheel motion mechanism of a tunnel cable inspection robot. Background technique [0002] In the existing wheel-type track running mechanism, the double-wheel structure is generally adopted. Although this solution makes the running of the trolley relatively stable, it takes up a large space and the turning is not very flexible. Special working conditions, so it cannot meet the requirements of the site. [0003] Secondly, the tread and the rim are generally of monolithic construction. In the case of long-distance applications such as tunnels, the maintenance of the track should be reduced as much as possible. However, when the wheel rolls on the track, the tread surface is in contact with the top surface of the track. There will be bumps, especially when turning, due to the centrifugal force, the wheels will have a strong cutting on the track, which w...
