Description

Technical Field

[0001] The invention relates to the technical field of cable pay-off, and in particular to a cable pay-off device suitable for cable assembly engineering. Background Art

[0002] The cable pay-off rack suitable for cable assembly engineering is also called cable reel bracket, conductor shaft reel bracket, cable pay-off bracket, etc. according to its use; it can be divided into hydraulic cable pay-off rack and mechanical cable pay-off rack according to the lifting form; it can be divided into adjustable hydraulic pay-off rack, column pay-off bracket, top rod cable pay-off rack, horizontal cable reel rack, foot brake cable pay-off rack, detachable cable pay-off rack, tension pay-off rack according to its use and structural form;

[0003] When many cable pay-off racks are performing cable pay-off work, as mentioned in the patent document with publication number CN113120692A, a front stopper that can move forward and backward is connected to the front front end of the top of the bottom rod of the rotating rack, and a stopper roller is rotatably connected to the top rear side of the front stopper. The cable drum is pulled at a uniform speed by the front traction force, so that the cable drum rotates on the rotating rack roller to achieve wire pay-off. The stopper roller blocks the rotatable front end of the cable drum, so that the cable drum will not slide off the front side of the bottom rod of the rotating rack due to force during wire pay-off, affecting normal wire pay-off. However, for the rotating rack roller on the bottom rod of the rotating rack, if the cable drum cannot be fully adapted to the rotating rack roller, it is easy to cause the cable drum to deflect left and right during rotation, and the cable drum is not limited to rotate, resulting in the cable and the cable outer sheet stored on the cable drum being in contact and wear during the wire pay-off process. At the same time, there is a lack of active braking of the cable drum, which causes the drum to continue to arrange wires after the subsequent cable pay-off stops.

[0004] To this end, we propose a cable pay-off device suitable for cable assembly engineering. Summary of the invention

[0005] The purpose of the present invention is to provide a cable pay-off device suitable for cable assembly engineering, so as to solve the problem that the cable drum fails to limit during the rotation and pay-off process proposed in the above background technology, resulting in the left and right deflection of the cable drum during the rotation process, causing friction between cables, and lacks active braking control in the later stage of the cable drum rotation;

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A cable pay-off device suitable for cable assembly engineering, comprising a pay-off frame, two sides of the pay-off frame are symmetrically slidably connected with a slide table, the bottom of the pay-off frame is movably connected with a threaded rod 1 through a bearing, one end of the threaded rod 1 passes through the slide table and is movably connected to the inner wall of the top of the pay-off frame;

[0008] A placement box is fixed to the inner wall of the bottom of the slide by bolts, and a slide column is slidably connected to the placement box. One end of the slide column penetrates the placement box and is slidably connected to the placement box. A rotating sleeve is installed in the slide column, and a slide rod is movably connected to the inner wall of the slide column. One end of the slide rod penetrates the rotating sleeve and is meshed and engaged with the rotating sleeve. A transmission tooth 2 is movably connected to the outer wall of the placement box. The central axis of the transmission tooth 2 penetrates one side of the placement box and is meshed and connected with a gear sleeved on the slide rod through a gear.

[0009] Furthermore, a transmission tooth 1 is movably connected to one side of the top of the placement box, and the transmission tooth 1 is meshed with a rotating tooth 2. A vertical frame is rotatably connected to one side of the slide through a bearing, and one side of the vertical frame is in contact with the outer wall of the slide column.

[0010] Furthermore, the outer wall of the sliding column is evenly provided with placement grooves, and an outer support block is slidably connected in the placement groove. The outer wall of the rotating sleeve is evenly provided with arc grooves, and a protrusion on one side of the outer support block is correspondingly engaged with the arc groove on the rotating sleeve.

[0011] Furthermore, a transmission box is fixed to the bottom of the pay-off frame by bolts, and a slider is symmetrically slidably connected to the bottom of the pay-off frame. Two threaded rods are symmetrically and movably connected on both sides of the transmission box, and one end of the two threaded rods respectively passes through the sliders on both sides and is movably connected to the side walls of the pay-off frame. The two sides of the slider are symmetrically and movably connected to the limit blocks, and one side of the vertical frame is clamped with the limit blocks.

[0012] Furthermore, a cam is symmetrically sleeved and movably connected on the outer wall of the second threaded rod, and a locking sleeve is slidably sleeved and connected on the second threaded rod on the cam side, and the locking sleeve is engaged with a hole on the cam.

[0013] Furthermore, one side of the pay-off frame is movably connected to a rocking wheel, and the bottom inner wall of the pay-off frame is movably connected to a rotating shaft, one end of the rotating shaft passes through one side of the pay-off frame and is fixed to the rocking wheel, and a fixed gear is symmetrically sleeved on the rotating shaft and is meshed with a gear at one end of the threaded rod.

[0014] Furthermore, one side of the pay-off frame is rotatably connected to an inclined plate, the top of the pay-off frame is slidably connected to a sliding box, the top of the pay-off frame is fixed with a placement plate by spot welding, and the top of the placement plate is evenly and movably connected to a guide wheel.

[0015] The cable laying method suitable for cable assembly engineering is:

[0016] For the storage of the cable rack, push the cable rack along the inclined plate on the pay-off rack, and the two sides of the cable rack contact the buffer pads on the pay-off rack respectively. Then manually turn the crank to drive the threaded rod on the pay-off rack to rotate, control the height of the slide, and align the center of the slide rod on one side of the placement box with the center of the central axis hole on the cable rack.

[0017] The wire is threaded in mid-air, and the rotation of the motor in the transmission box drives the rotation of the threaded rod 2. The two sliders on the threaded rod 2 move outward, and at the same time drive the vertical frame to rotate. The rotation of the vertical frame pushes the sliding column on one side of the placement box to move toward the central axis hole of the cable rack. Then the sliding column is stuck in the two sides of the cable rack. At this time, the motor on the top of the placement box is started, and the rotation of the motor drives the rotation of the transmission gear 1, so that the sliding rod in the placement box rotates. The rotation of the sliding rod drives the rotation of the rotating sleeve in the sliding column, and pushes the inner and outer support blocks of the placement groove to contact the outer wall of the central axis hole of the cable rack, completing the locking of the cable rack. As the threaded rod 2 continues to rotate, the cam on the threaded rod 2 disengages from the abutment against the buffer pad. At this time, the cables are passed through the slide box and multiple guide wheels in turn to perform the wire-releasing operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, by manually rotating the wheel on the pay-off frame, the side sliding column of the slide table is controlled to be flush with the central axis of the cable drum, and the cable drums of different sizes are adapted to be tightened and locked. Then, the transmission box is used to control the rotation of the two threaded rods on both sides of the bottom of the pay-off frame, so that the vertical frame on the slide table is rotated. At the same time, the sliding column on the outer side of the placement box is pushed to the center of both sides of the cable drum to complete the clamping and tightening of the cable drum. At the same time, considering the different diameters of the central holes of different cable drums, the motor is used to rotate to drive the second transmission gear on the placement box to rotate. The rotation of the second transmission gear drives the rotation of the inner sleeve of the sliding column, and the buffer block on the sliding column is pushed out to contact the inner wall of the cable drum to complete the locking of the cable drum, so as to avoid left and right deflection during the rotation of the cable drum, causing wear and damage between the cables.

[0020] 2. In the present invention, the rotation of the cam can be realized by rotating the second threaded rod. The cam is used to abut the buffer block on the pay-off frame to control the buffer block to slide up and down, giving the wire drum on the sliding column a suspended space, thereby reducing the resistance to the rotation of the wire drum. When there is no need to pay off the wire, the cam can also be used to rotate to contact the bottom edge of the wire drum in advance, thereby increasing the friction force of the wire drum rotation and realizing active braking of the wire drum, thereby avoiding the problem of continuous pay-off of the wire drum.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , the present invention provides a technical solution:

[0031] Embodiment 1: The cable is usually wound on a cable drum for transportation, and then the cable drum is supported by a cable retracting device, and the cable retracting operation is performed by rotating the cable drum, such as Figure 1 As shown, the entire pay-off rack 1 is the main body for storing the cable wheel. The entire cable wheel is lifted and suspended in the air by the extension mechanism of the slides 2 on both sides, and then the pay-off work is carried out. However, considering the problem of continuous pay-off caused by the rotation of the dragged cable wheel, the cable wheel continues to pay off the cable when there is no need to pay off the cable, which may cause cable abrasion in severe cases. Therefore, the cable wheel needs to be actively braked;

[0032] For this purpose, a buffer block 19 is symmetrically arranged on the entire pay-off frame 1 and an inclined plate 22 is arranged at the front end. The buffer block 19 is used to continuously contact and rub with the cable wheel to reduce its rotation speed. At the same time, the activity of the buffer block 19 can also provide a suspended environment for the cable wheel, without lifting the cable wheel, resulting in increased power consumption of the entire pay-off equipment;

[0033] like Figure 3As shown, considering the different diameters of cable wheels and the different sizes of center holes, in order to avoid affecting the normal rotation and pay-off of the cable wheels, slides 2 that can slide up and down are symmetrically arranged on both sides of the pay-off frame 1, and one side of the slide 2 is rotatably connected to the upper vertical frame 13, and one side of the vertical frame 13 extends to the bottom of the pay-off frame 1, and a sliding slider 16 that can slide is symmetrically arranged at the bottom of the pay-off frame 1, and the two sides of the slider 16 are movably connected to the upper limit blocks 17, and the limit blocks 17 are arranged in a square shape as a whole, and are clamped with the notches on both sides of the vertical frame 13, and the vertical frame 13 on the slide 2 can be rotated by driving the slider 16 to move left and right;

[0034] At the same time, since the diameter variation range of the cable wheel is relatively small, a cable wheel that is too small does not need a pay-off frame 1, and a cable wheel that is too large is not suitable for manual dragging. The entire slide 2 has a limited range of up and down activities, which prevents the end of the vertical frame 13 from escaping from the upper limit block 17 of the slider 16. As for the position adjustment of the slider 16, the motor in the transmission box 14 drives the threaded rod 2 15 to rotate, and the threaded slider 16 slides and drives the vertical frame 13 to rotate at the same time. In the initial state, the slide column 7 on one side of the placement box 4 is prevented from blocking the cable wheel from entering the pay-off frame 1, and the sliders 16 on both sides are close to or keep the vertical frame 13 vertical to the ground. After the cable wheel is pushed into the pay-off frame 1, the rear push rod and the manual cable wheel position adjustment are used to make the slide column 7 and the center hole of the cable wheel be on the same cutting plane;

[0035] However, considering that the slide column 7 and the central hole of the cable wheel are not on the same horizontal plane, it is necessary to rotate the wheel 20 on one side of the pay-off frame 1, such as Figure 2 As shown, the wheel 20 is connected to the bottom shaft 21 of the pay-off frame 1, and the shaft 21 rotates and drives the threaded rods 3 on both sides to rotate through the gears, thereby controlling the height of the slide 2 in the pay-off frame 1, and finally achieving that the slide column 7 is flush with the center hole of the cable wheel, but there is a distance between the two, and the cable wheel cannot be locked;

[0036] At this time, the position of the slider 16 is adjusted by rotating the motor in the transmission box 14, and the vertical frame 13 is driven to rotate by the movement of the slider 16. Figure 4 As shown, one side of the top of the vertical frame 13 is engaged with the outer wall of the slide post 7. When the vertical frame 13 rotates to the right, the slide post 7 on the placement box 4 will be pushed to move horizontally to the left, and the slide post 7 will be continuously pushed toward the center hole of the cable wheel;

[0037] like Figure 6 As shown, a cam 18 is also sleeved on the threaded rod 15, and the top of the cam 18 abuts against the buffer block 19 on the pay-off frame 1, that is, the raising and lowering of the buffer block 19 is controlled by the cam 18. Figure 7It can be understood that when the cam 18 rotates a certain angle, the height of the buffer pad 19 decreases. Therefore, by controlling the cam 18 to continuously contact the buffer pad 19 within the angle range, the vertical frame 13 is combined to push the slide post 7 to move a distance. That is, after the vertical frame 13 contacts the central hole of the cable wheel, the cam 18 rotates at this time to cause the buffer pad 19 to drop, and the unsupported cable wheel directly acts on the slide post 7. The cable wheel is suspended in the air using the slide posts 7 on both sides, so there is no need to actively lift the cable wheel in the air, and the overall power consumption of the cable pay-off equipment is reduced. At the same time, the cable wheel is more stable in the air.

[0038] However, considering that the rotation angle of the cam 18 must be adapted to the deflection angle of the vertical frame 13, it is necessary to control the contact angle of the cam 18 on the threaded rod 15 to deal with different cable wheels. For this purpose, the locking sleeve 26 is slidably connected to the cam 18 side of the threaded rod 15, and the locking sleeve 26 rotates with the threaded rod 15. First, the locking sleeve 26 is pulled out of the hole on the cam 18. At this time, the cam 18 without the locking sleeve 26 can rotate. Figure 7 Six holes are arranged on the outside of the cam 18 shown, so the minimum single adjustment angle of the cam 18 is controlled at 60°. The rotation angle of the cam 18 can be further reduced by changing the number of holes on the outside of the cam 18. Then, after the angle adjustment of the cam 18 is completed, the locking sleeve 26 is inserted to fix the cam 18. By adjusting the angle of the cam 18, the threaded rod 15 can be continuously rotated to push the sliding column 7 into the holes on both sides of the cable wheel, and at the same time, the buffer pad 19 can be driven to descend to realize the suspension of the cable wheel. At the same time, when the cable wheel needs to stop rotating, the threaded rod 15 is used to rotate in the opposite direction to realize the buffer pad 19 contacting the cable wheel first, thereby completing the braking of the cable wheel without causing the sliding column 7 to be separated from the abutment against the cable wheel. While reducing the overall power consumption of the wire-releasing equipment, active braking can also be performed to prevent the cable wheel from continuously rotating to release the wire.

[0039] Embodiment 2: Considering the problem that the diameter of the sliding column 7 is not compatible with the diameter of the holes on both sides of the cable wheel, in order to avoid the problem that the cable wheel is blocked from rotating due to the center of the sliding column 7 not being flush with the center of the holes on both sides of the cable wheel after the buffer block 19 is separated from the abutment against the cable wheel, after the sliding column 7 just enters the holes on both sides of the cable wheel, the rotation of the threaded rod 15 is stopped, and the motor located at the top of the placement box 4 starts to work;

[0040] like Figure 4 and Figure 5As shown, when the motor drives the transmission gear 1 5 to rotate, the transmission gear 2 6 located outside the placement box 4 rotates, and the rotation of the transmission gear 2 6 can realize the rotation of the slide bar 9 in the placement box 4. The straight stripes on the upper surface of the slide bar 9 drive the rotating sleeve 8 located in the outer support block 12 to rotate after the slide bar 9 rotates. The outer wall of the rotating sleeve 8 is evenly provided with arc grooves 10. At the same time, the outer support block 12 is slidably connected in the placement groove 11 on the outer wall of the slide column 7. The protrusion on one side of the outer support block 12 is clamped with the arc groove 10 on the rotating sleeve 8. When the slide bar 9 drives the cam 18 to rotate, the rotating sleeve 8 rotates and simultaneously pushes multiple outer support blocks 12 to abut against the outer walls of the central holes on both sides of the cable wheel. The outer support blocks 12 are used to achieve docking of the holes on both sides of the cable wheel. Subsequently, the threaded rod 2 15 continues to rotate, and the cable wheel can be stably abutted and locked.

[0041] Then the operator can pull out one end of the cable on the suspended cable wheel, slide along the top box 23 of the pay-off frame 1, pass one end of the cable through the roller on the slide box 23, and then pass them out one by one according to the placement position of the guide wheels 25 on the placement plate 24 to complete the cable pay-off operation. Through the installation of the slide box 23 and the guide wheel 25, the movement trajectory of the cable at the front end of the cable wheel is limited, thereby avoiding wear and damage caused by direct contact with the ground in the later stage of cable pay-off, and also facilitating the cable wheel to reel in the cable.

[0042] The working principle of the present invention is as follows: the cable rack is pushed and moved along the inclined plate 22 on the pay-off rack 1, and the two sides of the cable rack contact the buffer pads 19 on the pay-off rack 1 respectively, and then the rocker 20 is manually rotated to drive the threaded rod 3 on the pay-off rack 1 to rotate, control the rising height of the slide 2, and align the center of the slide rod 9 on one side of the placement box 4 with the center of the central axis hole on the cable rack;

[0043] The motor in the transmission box 14 rotates to drive the threaded rod 2 15 to rotate, and the two sliders 16 on the threaded rod 2 15 move outward, driving the vertical frame 13 to rotate at the same time. The vertical frame 13 rotates and pushes the sliding column 7 on one side of the placement box 4 to move toward the central axis hole of the cable rack. Then the sliding column 7 is stuck in the two sides of the cable rack. At this time, the motor at the top of the placement box 4 is started, and the rotation of the motor drives the transmission gear 1 5 to rotate, so that the sliding rod 9 in the placement box 4 rotates. The rotation of the sliding rod 9 drives the rotating sleeve 8 in the sliding column 7 to rotate, and pushes the inner and outer support blocks 12 of the placement groove 11 to contact the outer wall of the central axis hole of the cable rack, completing the locking of the cable rack. As the threaded rod 2 15 continues to rotate, the cam 18 on the threaded rod 2 15 disengages from the abutment against the buffer pad 19. At this time, the cable can be passed through the slide box 23 and multiple guide wheels 25 in sequence to perform the wire-laying operation.
