DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Example 1

[0025] A wire-retracting and arranging device for a pipeline detection robot, such as Figures 1 to 4 As shown, it includes a vehicle body 1, two silent wheels 25 are provided on the front side of the bottom of the vehicle body 1, and two universal brake wheels 29 are provided on the rear side. A switch 27, an emergency stop switch 28, a network cable interface 37, a power socket 36, etc. are provided on the outer wall of the vehicle body 1. A winding mechanism and a wire arrangement mechanism are provided inside the vehicle body 1, and the wire arrangement mechanism and the winding mechanism are transmission connected; specifically, a sprocket is provided at one end of the reciprocating screw rod 5 and the winding shaft 26, and the two sprockets are connected through a chain transmission. A tensioning wheel 11 is provided below the chain, and the tensioning wheel 11 is rotated on one side wall of the vehicle body 1 through the wheel axle.

[0026] The winding mechanism includes a winding shaft 26 that is rotatably arranged on the inner walls on both sides of the vehicle body 1, a winding roller 33 fixed on the winding shaft 26, a wire retaining disc 34 arranged at both ends of the winding roller 33, and a power mechanism that is transmission-connected to the winding shaft 26. The power mechanism is arranged below the reciprocating screw rod 5, and includes a drive motor 7 and an electromagnetic clutch 40. The drive motor 7 is transmission-connected to the winding shaft 26 through the electromagnetic clutch 40. The specific transmission method can be a sprocket chain method. When the device is powered off, in order not to affect the use of the device, the electromagnetic clutch 40 can separate the drive motor 7 from the winding shaft 26, so that the winding shaft 26 can be manually rotated by connecting a crank at one end of the winding shaft 26 to enable it to reel in and unreel normally. Specifically, a connecting sleeve can be fixedly connected to a square hole at one end of the winding shaft 26, and one end of the crank is designed as a square rod that matches the square hole. When in use, the square end of the crank can be conveniently inserted into the square hole.

[0027] The wire arrangement mechanism includes a reciprocating screw 5 that is rotatably arranged on the inner walls on both sides of the vehicle body 1, a moving block 9 that is threadedly engaged with the reciprocating screw 5, and a limiting assembly connected to the top of the moving block 9. A guide mechanism is provided below the reciprocating screw 5. The guide mechanism includes a guide rod provided on the inner walls on both sides of the vehicle body 1, a slider slidably mounted on the guide rod, and the slider is connected to the moving block 9 through a connecting plate 10. A front baffle 12 is provided on the front side of the guide rod, with both ends fixed on the inner walls on both sides of the vehicle body 1. A wire clamp 8 is provided at the upper end of the front baffle 12. After the wire is wound, the end of the wire is clamped in the wire clamp 8 for easy use next time. The limiting assembly includes a mounting frame fixed to the top of the moving block 9 and a guide wheel 19 that is rotatably arranged on the inner side of the mounting frame. The limiting assembly is connected to the moving block 9 through the connecting plate 10. The guide wheels 19 are divided into two groups, upper and lower, and each group has multiple guide wheels. To prevent the cable from shifting during arrangement, a guide wheel 19 located in the middle of the lower portion has a larger diameter than the other guide wheels 19 and is connected to an encoder 20. The encoder 20 counts the number of cable turns so that the controller can automatically stop the drive motor 7 when the cable is wound.

[0028] In order to better confine the cable between the upper and lower sets of guide wheels 19 , two longitudinal limiting rollers 18 are rotatably provided on the front and rear sides of the guide wheels 19 , and the cable passes between each two limiting rollers 18 .

[0029] A pull rod mechanism is provided at the rear of the winding mechanism. This mechanism comprises a rotating rod 42 that is laterally rotatably mounted on the inner walls of the vehicle body 1, a pull handle 41 located above the rotating rod 42, and a connecting rod 30 rotatably connected to both ends of the rotating rod 42 and the pull handle 41. Positioning seats 31 are provided on the inner walls of the vehicle body 1, each with a buckle 32. The ends of the pull handle 41 are clipped into the buckles 32. Universal brake wheels 29 are provided at the bottom of the vehicle body 1. To move the vehicle body 1 to a desired location, the pull handle is removed from the buckle 32 and pulled to easily move the entire vehicle body 1. Alternatively, handles can be provided on each side of the vehicle body 1 to move the entire vehicle body 1 by pulling the handles.

[0030] A brake mechanism is provided on one side of the cable arrangement mechanism, and the brake mechanism is arranged on a side away from the transmission mechanism. The brake mechanism includes a threaded column 2 rotatably arranged on a side wall of the vehicle body 1 and a fixed block 39, a tightening spring 38, and a friction wheel 35 connected in sequence to the threaded column 2. The threaded column 2 can be driven by an external motor. One end of the fixed block 39 is fixed to an inner wall of one side of the vehicle body 1 and is threadedly connected to the threaded column 2. The friction wheel 35 is rotatably connected to the other end of the threaded column 2. The tightening spring 38 is mounted on the threaded column 2, and its two ends are respectively connected to the friction wheel 35 and the threaded column 2. Specifically, the friction wheel 35 is arranged close to the corresponding wire disc 34. By rotating the threaded column 2 to squeeze the tightening spring 38, the friction wheel 35 is continuously pressed against the wire disc 34, and then the winding shaft 26 can be locked, thereby preventing accidental rotation and ensuring its safety.

[0031] The utility model drives the winding shaft 26 to rotate, so that the cable is wound and released through the winding roller 33. One end of the cable is fixed on the winding roller 33, and the other end passes through the guide wheel 19 and the limit roller 18 on the cable arrangement mechanism. Under the action of the reciprocating screw rod 5 and the moving block 9, the cables are evenly arranged when winding and releasing, thereby avoiding the problems of cable entanglement and knotting.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
