Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses from fixed detection car in pipeline. Referring to fig. 1, the pipeline internal self-fixing detection vehicle comprises a vehicle body 1, a camera 18 used for collecting the pipeline internal image is arranged on the upper surface of the vehicle body 1, a floating raft 19 is circumferentially arranged on the side wall of the vehicle body 1, air is filled in the floating raft 19, when the vehicle body 1 moves in a pipeline with water flow, the floating raft 19 can enable the vehicle body 1 to float on the water surface, and the camera 18 can better collect the pipeline internal image. The two sides of the width direction of the upper surface of the vehicle body 1 are fixed with a plurality of motors 2 through bolts, the motors 2 on the two sides are the same in number and are symmetrically arranged, in the embodiment, two motors 2 on each side are used for explaining, the output shaft of each motor 2 faces to the direction parallel to the moving advancing direction of the vehicle body 1, a fixing rod 3 is arranged on the output shaft of each motor 2, and the length direction of each fixing rod 3 is perpendicular to the length direction of the output shaft of each motor 2. When automobile body 1 need remove in the pipeline, starter motor 2 made the output shaft of motor 2 drive dead lever 3 and rotate, when dead lever 3 kept away from the one end butt of motor 2 in the lateral wall of pipeline, stopped motor 2 and started, four dead levers 3 butt respectively in the lateral wall of pipeline this moment, make the dolly whole can not the horizontal hunting in the pipeline to make camera 18 can gather comparatively clear image. In order to make the whole better removal of dolly, the one end of keeping away from motor 2 on dead lever 3 rotates and is connected with gyro wheel 5, and the axis of rotation of gyro wheel 5 is mutually perpendicular with the length direction of pipeline, and gyro wheel 5 is used for the lateral wall of butt pipeline, and when the dolly is whole to remove along pipeline length direction, gyro wheel 5 rotates along the pipeline lateral wall, makes the whole frictional force that receives of dolly less, and the dolly of being convenient for removes in the pipeline.

Referring to fig. 2, the fixing rod 3 includes a fixing portion 31 and a moving portion 32, the outer shapes of the fixing portion 31 and the moving portion 32 are cuboids, and the central lines of the fixing portion 31 and the moving portion 32 are arranged in the same line, an output shaft of the motor 2 (see fig. 1) is connected with one end of the fixing portion 31, which is far away from the moving portion 32, the roller 5 is rotatably connected with one end of the moving portion 32, which is far away from the fixing portion 31, a moving groove 6 for the moving portion 32 to be inserted and connected along the length direction of the fixing portion 31 is formed in one end of the fixing portion 31, which is far away from the output shaft of the motor 2, the radial cross-sectional shape of the moving groove 6 is the same as the radial cross-sectional shape of the moving portion 32, and the moving portion 32 can move in the moving groove 6 to change the length of the fixing rod 3. When the dead lever 3 needs to be used, the movable part 32 is moved to extend the length of the dead lever 3, so that the dead lever 3 can be used conveniently, when the dead lever 3 does not need to be used, the movable part 32 is moved to shorten the length of the dead lever 3, so that the dead lever 3 can be accommodated conveniently, the dead lever 3 can be attached to the upper surface of the trolley body 1, and the occupied space of the whole trolley is reduced, so that the trolley can be accommodated conveniently.

Referring to fig. 2 and 3, in order to reduce the occurrence of the situation that the moving portion 32 is completely moved out of the moving slot 6, a plurality of sliding blocks 14 are welded on the side wall of the end portion of the moving portion 32 close to the bottom surface of the moving slot 6, in this embodiment, two sliding blocks 14 are explained, the two sliding blocks 14 are symmetrically arranged with the center line of the moving portion 32 in the length direction, a sliding slot 15 for the sliding block 14 to slide along the depth direction of the moving slot 6 is formed in the side wall of the moving slot 6, and a clamping block 16 capable of being clamped with the sliding block 14 is welded on the side wall of the sliding slot 15 far from the bottom surface of the moving slot 6. When the moving part 32 moves in a direction away from the bottom surface of the moving groove 6, the sliding block 14 slides in the sliding groove 15 along with the movement of the moving part 32, and when the sliding block 14 moves to a position where it abuts against the engaging block 16, the sliding block 14 cannot move continuously in the original direction, so that the moving part 32 cannot move continuously in the original direction, and the situation that the moving part 32 moves completely out of the moving groove 6 and is separated from the fixed part 31 is reduced.
