DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] See also Figure 1-16 The embodiment of the present invention provides a wire-winding and tightening device for electric power construction, comprising a self-propelled mechanism 1, a wire-winding assembly 2 arranged on the self-propelled mechanism 1, and at least one cutting assembly, wherein the wire-winding assembly 2 is used to wind up the cable laid on the cable trench bracket, wherein the self-propelled mechanism 1 adopts the existing technology and will not be described in detail here; wherein the wire-winding assembly 2 adopts the existing technology, which specifically includes a fixed frame fixedly connected to the self-propelled mechanism 1, and a wire-winding roller for winding up the wire and a driving motor for driving the wire-winding roller to rotate are rotatably connected to the fixed frame; the cutting assembly includes an arc track 3, a sliding seat 4, a guide seat 5, a positioning platform 6, a trigger rod 8 and two cutters 7, and the arc track 3 is adjusted by the frame 1 3 is arranged on the self-propelled mechanism 1; the sliding seat 4 slides and cooperates with the arc track 3 along the preset path of the arc track 3; the guide seat 5 is slidably connected to the sliding seat 4; the positioning platform 6 is elastically rotatably connected to the guide seat 5; two cutters 7 are rotatably connected to the cutters 7 on the positioning platform 6, and a cutting station for cutting the cable tie is provided during the process of the two cutters 7 rotating and closing relative to the guide seat 5; the trigger rod 8 is movably arranged on the guide seat 5, and during the process of the trigger rod 8 following the movement of the self-propelled mechanism 1, the trigger rod 8 can abut and cooperate with each bracket one by one to drive the sliding seat 4 to slide and cooperate with the guide seat 5 and through the transmission mechanism 9 to make the two cutters 7 move to the cutting station to cut the cable tie, so that the take-up component 2 can reel up the cable. It should be noted that when the two cutters 7 are separated, a V-shaped blade can be formed, and there will be a gap between the cable tie and the bracket. At this time, when the self-propelled mechanism 1 moves along the direction of the cable groove, the cutter 7 abutting against the cable can pass through the gap so that the cable tie is located in the V-shaped blade so that the two cutters 7 can cut the cable tie; preferably, each cutter 7 has a guide edge at one end away from the positioning platform 6 so that the cutter 7 can pass through the gap. It should be further noted that the preset path of the arc track 3 is an arc groove opened on the arc track 3, and the sliding seat 4 is slidably connected in the arc groove. When the sliding seat 4 slides along the arc groove, the two cutters 7 can move along the circumference of the cable, thereby facilitating the adjustment of the orientation of the two cutters 7, so as to better drive the cutter 7 close to the cable skin into the gap formed between the cable tie and the cable, so that the two cutters 7 can perform the shearing work better.

[0018] It should be noted that the positioning platform 6 and the guide seat 5 are rotatably connected via a third rotating shaft, and a second torsion spring (not shown in the figure) is sleeved on the third rotating shaft, one end of the second torsion spring is fixedly connected to the positioning platform 6, and the other end is fixedly connected to the guide seat 5. The process of the second torsion spring restoring elastic deformation is used to drive the cutter 7 close to the outer surface of the cable to abut against the cable, so that the two cutters 7 follow the self-propelled mechanism 1 to move along the cable trench so that the cable tie tied between the cable and the bracket is located between the two cutters 7, thereby facilitating the two cutters 7 to rotate and close to the cutting station to cut the cable tie. At the same time, the setting of the second torsion spring can adapt to cables of different diameters, making it convenient for the corresponding cutter 7 to abut against the cable, thereby further improving the practicality of the entire device.

[0019] Specifically, when the self-propelled mechanism 1 is moving along the cable trench, the take-up assembly 2 will synchronously reel the cable in the cable trench on the self-propelled mechanism 1, thereby improving the reeling efficiency and reducing the friction between the cable and the bracket to reduce the risk of cable damage. At the same time, when the self-propelled mechanism 1 is moving, the trigger rod 8 can abut against each bracket, and in the process of abutting against any bracket, it will drive the sliding seat 4 to slide relative to the guide seat 5, that is, the cable tie is located in a V-shaped blade formed between the two cutters 7, and the sliding seat 4 continues to move with the self-propelled mechanism 1 and slides and closes the two cutters 7 through the transmission mechanism 9 to move to the cutting station to cut the cable tie, so that the take-up assembly 2 can reel the cable that is released from the cable tie, and the process is that the two cutters 7 will always be in this position to cut the cable tie located in the V-shaped blade, that is, it can be more convenient and better to cut the cable tie. The whole process allows the wire-reeling component 2 on the self-propelled mechanism 1 to cut the cable ties bundled between each bracket and the cable when combined with the cutting mechanism, and the wire-reeling component 2 will reel in the cable without manual cutting, which not only reduces the workload of the staff, but also improves the wire-reeling efficiency of the wire-reeling component when it is working.

[0020] The transmission mechanism 9 includes two guide grooves 91, a slide 92, a transmission part 94, a toothed belt transmission unit 95, a first gear 96 and a first rack 97. The two guide grooves 91 are respectively provided on the corresponding cutter 7. The guide groove 91 includes a first slide groove 911, an inclined groove 912 and a second slide groove 913 which are connected in sequence. The slide 92 is slidably connected to the positioning platform 6. Two first sliders 93 corresponding to each guide groove 91 are fixedly connected to the slide 92, and each first slider 93 is slidably matched with the corresponding guide groove 91. The transmission part 94 includes a curved wheel 941 rotatably connected to the positioning platform 6, an eccentrically A crank 942 fixedly connected to the crank wheel 941 and a straight groove slide rail 943 fixedly connected to the slide 92 through a first guide rod, the crank 942 and the straight groove slide rail 943 are slidably connected; the toothed belt transmission unit 95 includes a driven gear 951 coaxially fixedly connected to the crank wheel 941, a driving gear 952 rotatably connected to the guide seat 5, and a transmission toothed belt 953 arranged between the driven gear 951 and the driving gear 952; the first gear 96 is coaxially fixedly connected to the driving gear 952; the first rack 97 is fixedly connected to the slide seat 4, and the first rack 97 can mesh with the first gear 96. It should be noted that the first gear 96, the driving gear 952 and the third rotating shaft are located on the same axis, which is convenient for the second torsion spring to drive the positioning platform 6 to rotate relative to the guide seat 5 during the process of restoring elastic deformation, and does not affect the driving gear 952 in the toothed belt transmission unit 95 to accept the drive of the first gear 96 and rotate the driven gear 951 under the cooperation of the transmission toothed belt 953.

[0021] Specifically, when the trigger rod 8 is in contact with the bracket, the sliding seat 4 and the guide seat 5 are driven to slide relative to each other, that is, the sliding seat 4 drives the first rack 97 to mesh with the first gear 96 so that the first gear 96 drives the driving gear 952 to rotate, and the driven gear 951 can drive the crank 941 to rotate under the cooperation of the transmission belt 953, so that the crank 942 can also slide along the linear slide rail during the process of following the rotation of the crank 941, so that the slide 92 moves linearly relative to the positioning table 6, and then the two first sliders 93 slide along the corresponding guide grooves 91 synchronously, so that the two cutters 7 rotate and close to the cutting station to cut the cable tie. Further, the process of the two first sliders 93 driving the corresponding cutters 7 to rotate and close to the cutting station is as follows: the first slider 93 slides from the second slide groove 913 to the inclined groove 912, and the corresponding cutter 7 rotates until it moves to the first slide groove 911 under the cooperation of the inclined groove 912, that is, the two cutters 7 are driven to close and move to the cutting station.

[0022] A first elastic member 10 is provided between the guide seat 5 and the sliding seat 4. The process of the first elastic member 10 restoring elastic deformation is used to drive the guide seat 5 to slide relative to the sliding seat 4. Figure 5-8As shown, the first elastic member 10 includes a slide rod and a first spring, and the slide rod is fixedly connected to the guide seat 5. Based on this, the first spring is sleeved on the rod body of the slide rod, and one end of the first spring is fixedly connected to the guide seat 5, and the other end is fixedly connected to the slide seat 4. Among them, the guide seat 5 is rotatably connected to a hinge seat 11 through a first rotating shaft, and the hinge seat 11 is rotatably connected to the trigger rod 8 through a second rotating shaft, and a first torsion spring 12 is sleeved on the second rotating shaft, and one end of the first torsion spring 12 is fixedly connected to the trigger rod 8, and the other end is fixedly connected to the hinge seat 11. Among them, it should be noted that the elastic force of the first torsion spring 12 to restore the elastic deformation is greater than the elastic force of the first elastic member 10 to restore the elastic deformation. It should be further explained that when the trigger rod 8 abuts against the bracket, the first torsion spring 12 has not yet undergone any deformation. At this time, the first elastic member 10 will be compressed first under the sliding cooperation between the guide seat 5 and the sliding seat 4. When the first elastic member 10 is compressed to the maximum deformation degree, the two cutters 7 will be located at the cutting station and cut the cable tie. Then the sliding seat 4 will continue to move with the self-propelled mechanism 1. At this time, the first torsion spring 12 begins to deform until the trigger rod 8 rotates a certain angle relative to the bracket and moves with the self-propelled mechanism 1 until it passes After passing through the bracket, the first elastic member 10 restores its elastic deformation to drive the guide seat 5 to return to slide relative to the sliding seat 4. At this time, the first rack 97 will cooperate with the first gear 96 and under the cooperation of the toothed belt transmission unit 95 and the transmission part 94, the two first sliders 93 slide along the corresponding guide grooves 91, that is, the first sliders 93 slide along the first slide grooves 911 and the inclined grooves 912 in the corresponding guides in sequence until they move into the second slide grooves 913. At this point, the two cutters 7 rotate out of the cutting station so that the two cutters 7 can cut the next cable tie.

[0023] The axis of the first rotating shaft and the axis of the second rotating shaft are arranged perpendicular to each other. It should be noted that when the sliding seat 4 slides along the preset path of the arc track 3, the trigger rod 8 can be kept in a vertical state relative to the bracket by its own gravity and with the cooperation of the first rotating shaft, so that the trigger rod 8 can better abut with the bracket, thereby driving the two cutters 7 to perform cutting work. Preferably, the abutting surface of the trigger rod 8 and the bracket is wrapped with an elastic soft rubber pad, which can effectively prevent the trigger rod 8 from being damaged when it abuts with the bracket.

[0024] As a preferred embodiment of the present invention, the adjustment frame 13 includes a vertical frame 131 and a horizontal frame 132. The vertical frame 131 is fixedly connected to the self-propelled mechanism 1; the horizontal frame 132 is vertically slidably connected to the vertical frame 131, and the arc track 3 is slidably connected to the horizontal frame 132 through a moving platform. It should be noted that the horizontal frame 132 is slidably connected to the vertical frame 131 through a sliding sleeve, and a first bolt is threadedly connected to the sliding sleeve, and the inner end of the first bolt can be abutted against the vertical frame 131. Based on this, when the horizontal frame 132 is slidably adjusted along the vertical frame 131 to a suitable height, the first bolt is tightened to make the inner end of the first bolt abut against the vertical frame 131, thereby completing the locking of the horizontal frame 132; preferably, the mobile platform is threadedly connected to a second bolt, and similarly, the inner end of the second bolt can abut against the horizontal frame 132. After the mobile platform is slidably adjusted to a certain position along the horizontal frame 132, the second bolt can also be tightened to make the inner end of the second bolt abut against the horizontal frame 132, thereby completing the locking of the mobile platform. The whole process can be adapted to the winding of cables of different heights on the bracket and different cables of the same height.

[0025] As a further preferred embodiment of the present invention, the mobile platform is further provided with a driving mechanism 14 for driving the sliding seat 4 to slide along a preset path of the arc track 3. The driving mechanism 14 includes a first cylinder 141 and an elastic telescopic rod 142. The first cylinder 141 is fixedly connected to the mobile platform; one end of the elastic telescopic rod 142 is fixedly connected to the air rod of the first cylinder 141, and the other end is rotatably connected to the sliding seat 4. Specifically, according to Figure 13-14 As shown, the air rod of the first air cylinder 141 drives the elastic telescopic rod 142 to move linearly and with the cooperation of the elastic telescopic rod 142, the sliding seat 4 can slide only along the preset path of the arc track 3. Preferably, a visual camera (using the existing technology, which will not be described in detail here) can be provided on the mobile platform, and a controller electrically connected to the first air cylinder 141 and the visual camera is provided. Under the control of the controller, the visual camera and the first cylinder 141 work in coordination, that is, the visual camera is used to observe the gap between the cable tie and the cable, so as to control the first air cylinder 141 to work so that the sliding seat 4 slides along the preset path of the arc track 3.

[0026] In order to arrange the take-up assembly 2 evenly on the take-up roller when winding the cable, as a further preferred embodiment of the present invention, Figure 15-16As shown, the self-propelled mechanism 1 is fixedly connected to a gantry 15, and a reciprocating screw rod 16 is vertically elastically slidably connected to the gantry 15, and a nut sleeve 17 is threadedly connected to the reciprocating screw rod 16, and the two sides of the nut sleeve 17 are elastically slidably connected to limit baffles 18. It should be noted that the gantry 15 is vertically slidably connected to two second sliders, and the reciprocating screw rod 16 is fixedly connected between the two second sliders. It should be further noted that each second slider is elastically slidably connected to the gantry 15 through a second spring 19, one end of the second spring 19 is fixedly connected to the corresponding second slider, and the other end is fixedly connected to the gantry 15. Preferably, the two limit baffles 18 are elastically connected to the nut sleeve 17 through a third spring 20, and the process of the third spring 20 restoring elastic deformation is used to drive the corresponding limit baffle 18 to slide close to the nut sleeve 17, so that the two limit baffles 18 have a certain clamping force on the cable and are suitable for cables of different diameters. Among them, the outer surface of the nut sleeve 17 is wrapped with a rubber pad to increase the friction between the nut sleeve 17 and the cable.

[0027] Specifically, before the winding roller of the winding assembly starts to wind up the cable, the cable is first placed under the nut sleeve 17 and the cable is clamped by the cooperation between the two limit baffles 18 and the third spring 20. At this point, when the winding roller starts to wind up, the friction between the cable and the nut sleeve 17 can drive the nut sleeve 17 to slide back and forth and rotate relative to the reciprocating screw rod 16, so that the cable can be orderly driven to be evenly wound on the winding roller. Preferably, as the diameter of the cable on the winding roller is wound into a cylinder, the reciprocating screw rod 16 is driven to move upward relative to the gantry 15, and the second spring 19 is compressed. The second spring 19 will give a downward force relative to the reciprocating screw rod 16, which has the effect of tightening and straightening the cable, and can effectively prevent the cable wound on the winding roller from becoming loose.

[0028] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
