In the description of the present invention, the meaning of "a plurality" is more than two, unless otherwise clearly specifically limited.

[0029] Such as Figure 1-7As shown in the figure, the present invention provides a wiring tool for monitoring thermal instruments in a power plant, including a control cabinet. This tool is used for cutting operations on two busbars. The busbar consists of an insulating skin and multiple wires, and the insulating skin wraps around the periphery of the multiple wires. The busbar is a prior art, and its specific structure will not be elaborated here. This tool also includes a bottom plate 10, a moving mechanism 20, and an annular cutting mechanism 30.

[0030] A plurality of suction cups 11 are fixedly installed at the bottom of the bottom plate 10.

[0031] The moving mechanism 20 includes a guide rod 21, a bidirectional lead screw 22, and a first motor 23. The guide rod 21 and the bidirectional lead screw 22 are both arranged horizontally above the bottom plate 10 and are parallel to each other. Both ends of the guide rod 21 are fixedly connected to the bottom plate 10. The spiral directions of the threads at both ends of the bidirectional lead screw 22 are opposite, and both ends of the bidirectional lead screw 22 are rotatably connected to the bottom plate 10. The first motor 23 is fixedly installed on the bottom plate 10 and is used to control the rotation of the bidirectional lead screw 22. The first motor 23 is electrically connected to the control cabinet, and the control cabinet is used to control the operation of the first motor 23.

[0032] There are two annular cutting mechanisms 30, and the two annular cutting mechanisms 30 are respectively located at both ends of the bidirectional lead screw 22. The annular cutting mechanism 30 includes a moving seat 31, a turning plate 32, a fixed seat 33, a rotating cylinder 34, a driving component 40, a tool component 50, and a control component 60. The moving seat 31 is arranged on the bidirectional lead screw 22 and is threadedly connected to the bidirectional lead screw 22. The moving seat 31 is also slidably connected to the guide rod 21. A plurality of first arc-shaped grooves 311 that penetrate horizontally and extend downward are formed at the top of the moving seat 31. The turning plate 32 is arranged above the moving seat 31. The first side of the turning plate 32 is rotatably connected to the moving seat 31, and the second side of the turning plate 32 is detachably connected to the moving seat 31. A plurality of second arc-shaped grooves 321 that penetrate horizontally and extend upward are formed at the bottom of the turning plate 32. The plurality of second arc-shaped grooves 321 are arranged in one-to-one correspondence with the plurality of first arc-shaped grooves 311. Both the second arc-shaped grooves 321 and the first arc-shaped grooves 311 are adapted to the wires. There are two fixed seats 33, and the two fixed seats 33 are respectively fixedly installed at both ends of the top of the turning plate 32. A limiting hole 331 that penetrates horizontally is formed in the fixed seat 33, and the limiting hole 331 is adapted to the busbar. The rotating cylinder 34 is arranged horizontally between the two fixed seats 33 and is rotatably connected to the two fixed seats 33 at both ends. The inside of the rotating cylinder 34 is aligned and communicated with the limiting hole 331. A notch 341 that penetrates inward is formed on the outer wall of the rotating cylinder 34. The driving component 40 is used to control the rotation of the rotating cylinder 34. The tool component 50 is arranged on the outer wall of the rotating cylinder 34. The control component 60 is used to control the tool component 50 to pierce the insulating skin.

[0033] In the initial state, the tool component 50 is located on the outer wall of the rotating cylinder 34.

[0034] Before the cutting operation, the staff first adsorb the bottom plate 10 on the instrument box through the suction cup 11, and then insert the two busbars into the limit holes 331 and the rotating cylinders 34 of the two annular cutting mechanisms 30 respectively, and hold the two busbars with both hands.

[0035] The two annular cutting mechanisms 30 respectively perform cutting operations on the two busbars.

[0036] The specific process of the cutting operation is as follows: The control component 60 controls the tool component 50 to extend into the notch 341 until the tool component 50 pierces the insulating skin of the busbar. Then the driving component 40 controls the rotating cylinder 34 to rotate, so that the tool component 50 will rotate one circle, thereby cutting the insulating skin along the circumferential direction as a whole. Then the control cabinet controls the first motor 23 to start, and the first motor 23 drives the bidirectional lead screw 22 to rotate. Under the action of the guide rod 21, the two moving seats 31 will approach each other, and the tool component 50 will automatically push the cut insulating skin forward and make it peel off, which is convenient for the staff to use. At this time, the wire is exposed, and the cutting operation is completed.

[0037] After the cutting operation is completed, the control cabinet controls the first motor 23 to start again, and the first motor 23 drives the bidirectional lead screw 22 to reverse. Under the action of the guide rod 21, the moving seat 31 moves outwards to reset. Then the staff opens the flip plate 32 and turns its second side upwards, places the multiple wires in the first limit grooves respectively in one-to-one correspondence, then closes the flip plate 32, and connects the second side of the flip plate 32 to the bottom plate 10, so that all the wires will be respectively restricted one by one. The wires exposed in the two busbars all face the middle of the bottom plate 10, and under the restrictive action of the first arc groove 311 and the second arc groove 321, the wires to be connected in the two busbars are arranged in one-to-one correspondence, thus facilitating the staff to accurately connect the wires, avoiding the staff from arranging the wires while connecting the wires, and improving the wiring efficiency.

[0038] In one embodiment, the driving component 40 includes a first gear 41, a second motor 42 and a second gear 43. The first gear 41 is fixedly installed on the rotating cylinder 34. The second motor 42 is fixedly installed on the fixed seat 33 and is electrically connected to the control cabinet, and the control cabinet is used to control the second motor 42 to work. The second gear 43 is fixedly installed on the output shaft of the second motor 42 and meshes with the first gear 41.

[0039] When the driving component 40 is started, the control cabinet controls the second motor 42 to start, the second motor 42 drives the second gear 43 to rotate, and under the transmission action of the first gear 41, the rotating cylinder 34 will rotate, so that the tool component 50 cuts the insulating skin along the circumferential direction as a whole.

[0040] The structure of this driving component 40 is simple, and it is convenient for use, manufacturing and production.

[0041] In one embodiment, there are two notches 341, and the two notches 341 are respectively located on both sides of the rotating cylinder 34.

[0042] Correspondingly, there are also two tool assemblies 50, and the two tool assemblies 50 are respectively arranged on both sides of the rotating cylinder 34 and are in one-to-one correspondence with the two notches 341. The tool assembly 50 includes a rotating plate 51, a cutting tool 52, a guide shaft 53, an arc-shaped guide rail 54, a slider 55 and a guide plate 56. The first end of the rotating plate 51 is rotatably connected to the rotating cylinder 34 through a connecting shaft 57. The cutting tool 52 is fixedly installed at the bottom of the rotating plate 51 and is adapted to the notch 341. The guide shaft 53 is arranged transversely and is connected to the outer wall of the first end of the rotating plate 51. The arc-shaped guide rail 54 is fixedly installed on the rotating cylinder 34 along the circumferential direction. The slider 55 is arranged on the arc-shaped guide rail 54 and is slidably connected to the arc-shaped guide rail 54. The guide plate 56 is fixedly installed on the slider 55. A guide groove 561 that penetrates transversely and extends obliquely outward is formed in the guide plate 56, and the inner wall of the guide groove 561 is slidably connected to the guide shaft 53.

[0043] The working process of the tool assembly 50 is as follows: The driving assembly 40 controls the movement of the guide plate 56, and the slider 55 will move synchronously on the arc-shaped guide rail 54. Since the inner wall of the guide groove 561 is slidably connected to the guide shaft 53, and the guide groove 561 penetrates transversely and extends obliquely outward, the inner wall of the guide groove 561 will drive the guide shaft 53 to rotate outward. The guide shaft 53 drives the first end of the rotating plate 51 to rotate synchronously. Under the action of the connecting shaft 57, the cutting tool 52 will enter the notch 341, thereby piercing the insulating skin.

[0044] The two tool assemblies 50 pierce both sides of the insulating skin at the same time. On the one hand, with the cooperation of the driving assembly 40, the insulating skin can be quickly cut off along the circumferential direction as a whole; on the other hand, with the cooperation of the moving mechanism 20, the cut insulating skin can be stably pushed forward and peeled off, improving the stability during peeling.

[0045] In one embodiment, the guide shaft 53 is rotatably connected to the first end of the rotating plate 51. In this way, when the tool assembly 50 works, the guide shaft 53 will roll in the guide groove 561, thereby reducing the friction between the guide shaft 53 and the inner wall of the guide groove 561 and making the tool assembly 50 work more smoothly.

[0046] In one embodiment, the control assembly 60 includes an arc rack 61, a third motor 62, and a third gear 63. There are two arc racks 61, and the two arc racks 61 are respectively fixedly connected to the guide plates 56 in the two tool assemblies 50. The third motor 62 is fixedly installed on the rotating cylinder 34 and is electrically connected to the control cabinet, and the control cabinet is used to control the operation of the third motor 62. The third gear 63 is fixedly installed on the output shaft of the third motor 62 and is located between the two arc racks 61, and the third gear 63 meshes with both of the two arc racks 61.

[0047] When the driving assembly 40 works, the control cabinet controls the third motor 62 to start. The third motor 62 drives the third gear 63 to rotate. Since the two arc racks 61 are respectively located above and below the third gear 63, the two arc racks 61 will approach or move away from each other, thereby driving the guide plates 56 and the sliders 55 in the two tool assemblies 50 to approach and move away from each other, and further controlling the corresponding tool assemblies 50 to work.

[0048] In one embodiment, screws 35 are provided on the second side of the turning plate 32. The threaded ends of the screws 35 pass through the turning plate 32 and are in threaded cooperation with the bottom plate 10. The detachable connection between the turning plate 32 and the bottom plate 10 is realized through the screws 35, and the structure is simple and convenient for the staff to operate.

[0049] In one embodiment, the first side of the turning plate 32 is rotatably connected to the bottom plate 10 through a rotating shaft. A torsion spring 36 is sleeved on the rotating shaft. The first end of the torsion spring 36 is fixedly connected to the turning plate 32, and the second end of the torsion spring 36 is fixedly connected to the bottom plate 10. The torsion spring 36 makes the second side of the turning plate 32 tend to turn upward.

[0050] When the staff unscrew the screws 35, under the action of the torsion spring 36, the second side of the turning plate 32 will automatically turn upward, so as to facilitate the staff to place the wire in the first arc groove 311.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
