Detailed Description

The cable center self-positioning device of the present invention is further described with reference to fig. 1 to 3.

A cable center self-positioning device is characterized in that: comprises a shell, a limit rod group, an elastic reset piece 11 and a driving part 1. The housing comprises a rear end cap 9 and a front cover 2 covering the rear end cap 9. The gag lever post group includes left gag lever post 5 and right gag lever post 6, the upper end of left side gag lever post 5 and the upper end of right gag lever post 6 are all through pivot 7 rotatable coupling on the rear end cap 9 of shell to mutually support and form synchronous reverse rotation structure, the body of rod part of left side gag lever post 5 with the body of rod part of right gag lever post 6 extends to the outside of shell, and forms cable spacing groove 15 each other. Elasticity piece 11 is the spring and connects between left gag lever post 5 and right gag lever post 6, provides pivoted pulling force in opposite directions for left gag lever post 5 and right gag lever post 6. The driving part 1 is arranged on the front cover 2 of the shell and is matched with the limiting rod group through a linkage assembly so as to drive the left limiting rod 5 and the right limiting rod 6 to rotate back to back.

Based on the structure, the utility model is fixed on the inspection robot when in use, and the left limiting rod 5 and the right limiting rod 6 are driven by the driving part 1 to rotate in the opposite directions, so that the cable can enter the cable limiting groove; when in inspection and positioning, the driving part 1 cancels the rotating force provided for the limiting rod group, and the left limiting rod 5 and the right limiting rod 6 rotate oppositely under the action of the spring, so that the rod body part of the left limiting rod 5 and the rod body part of the right limiting rod 6 clamp the cable tightly; when the inspection robot moves along the cable, if the inspection robot slides along the direction of a driving wheel shaft of the inspection robot, one of the left limiting rod 5 and the right limiting rod 6 is close to the cable, and the other limiting rod is far away from the cable, so that the clamping force of the left limiting rod 5 and the right limiting rod 6 is completely acted on the limiting rods close to the cable, the sliding of the cable obtains a force for correcting the cable to the center, and the center of the driving wheel along the direction of the cable can be automatically corrected and positioned; therefore, only when the cable is in the central position, the two sides of the clamping force are balanced, and the cable is not subjected to sliding force, so that automatic deviation rectification and central positioning can be realized.

Specifically, the opposite surfaces of the upper ends of the left limiting rod 5 and the right limiting rod 6 are respectively provided with mutually meshed tooth grooves. Through the intermeshing of tooth's socket, when one of them gag lever post rotated, another gag lever post can synchronous counter rotation, had simple structure compactness, small and exquisite, was convenient for the utility model discloses the installation on patrolling and examining the robot.

And the rod body part of the left limiting rod 5 and the rod body part of the right limiting rod 6 are both provided with a roll shaft 12. The roller shaft 12 can reduce the frictional resistance between the roller shaft and the cable, and is convenient for the inspection robot to walk on the cable.

The left limiting rod 5 and the right limiting rod 6 are both provided with connecting plates 10, connecting columns 4 are inserted into the connecting plates 10, and the elastic reset pieces 11, namely two ends of the springs, are sleeved on the two connecting columns 4 respectively to provide clamping force for the left limiting rod 5 and the right limiting rod 6.

The driving part 1 is a motor, and the linkage assembly comprises a swing arm 3 and a roller 14. The swing arm 3 is sleeved on an output shaft of the motor and rotates along with the output shaft. The roller 14 is installed on one end of the swing arm 3, which faces away from the output shaft, and the roller 14 can abut against the inner side surface of the left limiting rod 5 or the right limiting rod 6 when rotating along with the swing arm 3 so as to drive the left limiting rod 5 and the right limiting rod 6 to rotate back to back. Because the tooth sockets on the left limiting rod 5 and the right limiting rod 6 are matched, the motor only needs to drive one limiting rod to rotate, and the other limiting rod can also reversely rotate along with the one limiting rod, so that the structure is simple, and the use is convenient; when the motor cancels the thrust on the left limiting rod 5 or the right limiting rod 6, the motor moves to the zero position, namely the swing arm 3 is in the vertical position.

Still be provided with circuit board 8 in the shell, this circuit board 8 is fixed in on the rear end cover 9, be provided with on the circuit board 8 and be used for detecting left gag lever post 5 with right gag lever post 6 turned angle's hall element.
