Description

Technical Field

[0001] The present invention relates to a cable arranging device, belonging to the technical field of wire winding equipment. Background Art

[0002] The cable arranging operation is the process of arranging cables in a cable pool in sequence. The traditional cable arranging method mainly relies on manual labor at the end, with high labor intensity, and it takes about 20 days to complete the winding of one cable reel. The existing cable arranging devices mainly arrange cables by driving a swing arm through a lifting device to control the output position of the cables. During the working process, since the swing arm is controlled along a fixed moving route, the newly arranged cables will not closely fit the already arranged cables at some positions, so manual real-time adjustment is still required. Summary of the Invention

[0003] Aiming at the above-mentioned defects of the prior art, the task of the present invention is to provide an automatic compacting cable arranging device to solve the problem that the end of the cable lacks control and the newly arranged cables cannot closely fit the already arranged cables.

[0004] The technical solution of the present invention is as follows: An automatic compacting cable arranging device includes a horizontal guide rail, a transverse moving mechanism, a cable feeding device, and a compacting mechanism. The transverse moving mechanism is arranged on the horizontal guide rail and can move along the horizontal guide rail. The cable feeding device is connected to the transverse moving mechanism for threading the cable. The compacting mechanism includes a frame structure, a horizontal squeezing roller mechanism, and a vertical pressing roller mechanism. The frame structure is rotatably connected to the transverse moving mechanism. The vertical pressing roller mechanism is connected to the frame structure. The vertical pressing roller mechanism includes a horizontally arranged pressing roller and a first lifting mechanism. The horizontal squeezing roller mechanism is connected to the frame structure. The horizontal squeezing roller mechanism includes a vertically arranged pair of squeezing rollers and a translation mechanism. The pair of squeezing rollers is located in front of one end of the pressing roller. The cable passes through the side of the pair of squeezing rollers and is located below the pressing roller. The translation mechanism is used to drive the pair of squeezing rollers to approach or move away from the pressing roller so that the cable is horizontally closely attached to the already arranged cables in the same layer. The first lifting mechanism drives the pressing roller to lift and lower so that the cable is longitudinally closely attached to the already arranged cables in the lower layer.

[0005] Further, in order to expand the activity range of the horizontal squeezing roller mechanism and the vertical pressing roller mechanism and make them more flexible in adjusting the angle when approaching the center and the outer wall of the cable pool, a swing arm is connected between the frame structure and the transverse moving mechanism. The head end of the swing arm is rotatably connected to the frame structure, and the tail end of the swing arm is rotatably connected to the transverse moving mechanism. When the swing arm rotates, the head end of the swing arm swings.

[0006] Furthermore, in order to reduce the weight of the compacting mechanism and facilitate the accurate control of the swinging position of the swing arm, a rotating shaft rotatably connected to the head end of the swing arm is provided on the frame structure. A driven pulley is provided at the top end of the rotating shaft. A driving pulley and a rotating motor are provided at the end of the swing arm. The rotating motor drives the driving pulley to rotate, and a first transmission belt is wound around the driving pulley and the driven pulley.

[0007] Furthermore, the first lifting mechanism includes a moving base driven to lift by a first driving device. A spring with a guide post is connected to the lower end of the moving base. The lower end of the spring is connected to the mounting base plate, and the pressing roller is rotatably connected to the mounting base plate. The telescoping of the spring can adapt to the height of the cable. Within a certain range of uneven cable heights, it is not necessary to frequently adjust the height position of the moving base, and at the same time, it is avoided that the first driving device applies too large a load on the cable and causes damage.

[0008] Furthermore, the translation mechanism includes a base, a driving motor, a driving gear, a guide rail, and a suspension base plate. The base is fixed to the frame structure. The driving motor is fixedly connected to the base. The driving gear is driven by the driving motor. The base is fixedly connected with a guiding member. The guiding member is provided with a horizontally arranged guiding groove. The guide rail is slidably arranged in the guiding groove and fixedly connected to the suspension base plate. A rack meshing with the driving gear is provided on the guide rail. The driving gear drives the guide rail to move along the guiding groove through the rack, and the roller shafts of the pair of squeezing rollers are connected to the suspension base plate.

[0009] Furthermore, the driving motor is a bidirectional motor, and there are two guiding grooves and two guide rails, which are symmetrically located on both sides of the bidirectional motor. The structure of the two-way symmetric arrangement ensures uniform force during the cable laying process.

[0010] Furthermore, in order to improve the stability of the movement of the guide rail, sliding grooves are provided on both sides of the guide rail, guide pins cooperating with the sliding grooves are provided on both sides of the guiding groove, and a guiding body is provided on the top surface of the suspension base plate. The guiding body is slidably matched with the bottom surface of the guiding member.

[0011] Furthermore, in order to facilitate the rapid adjustment of the heights of the lateral squeezing roller mechanism and the vertical pressing roller mechanism, the frame structure includes a fixed frame, a movable frame, and a second lifting mechanism. Both the lateral squeezing roller mechanism and the vertical pressing roller mechanism are connected to the movable frame. The movable frame is connected to the fixed frame through the second lifting mechanism. The second lifting mechanism drives the movable frame to lift, and the fixed frame is rotatably connected to the transverse movement mechanism.

[0012] Further, in order to reduce the stress generated by the cable during the cable laying process and make it difficult to arrange the cable neatly, the cable feeding device includes a cable feeding base, a sleeve, a clamping head, a torque sensor, and a stress release motor. The sleeve is rotatably arranged on the cable feeding base and is driven to rotate by the stress release motor. The torque sensor is used to measure the rotational torque generated by the rotation of the sleeve when the cable passes through the sleeve. The stress release motor drives the sleeve to rotate according to the rotational torque to reduce the rotational torque. At least three clamping heads are provided and arranged inside the sleeve. The clamping heads are respectively located on both sides of any diameter of the sleeve. The head end of the clamping head is provided with a clamping roller. A plurality of circumferential grooves are provided on the clamping roller. The rolling direction of the clamping roller is the axial direction of the cable. The cable passes through the sleeve and is output by the compacting mechanism.

[0013] Further, the clamping head includes a fixed seat and a rotating arm. The clamping roller is arranged at the head end of the rotating arm. The fixed seat is fixed to the wall of the sleeve. A clamping spring is arranged between the fixed seat and the rotating arm. The clamping spring makes the clamping roller closely adhere to the outer wall of the cable.

[0014] Compared with the prior art, the advantages of the technical solution of the present invention are as follows: By arranging the transverse squeezing roller mechanism and the vertical pressing roller mechanism, the cable can be longitudinally and transversely squeezed during the output arrangement process of the cable, ensuring that the cable arrangement is compact. By the rotation of the sleeve in the cable feeding device, the cable can be in a free tension state, which is beneficial to the subsequent compacting operation of the cable rope.

[0025] The present invention will be further described below in conjunction with embodiments, but it is not a limitation to the present invention.

[0026] Please refer to Figure 1 As shown, the automatic compacting cable arranging device involved in the embodiment of the present invention includes a horizontal guide rail 1, a traversing mechanism 2, a cable feeding device 3, a swing arm 4, and a compacting mechanism 5. The automatic compacting cable arranging device of this embodiment can be installed at the front end of a self-propelled cable arranging trolley. The specific structure of the cable arranging trolley can be the vehicle body 6 part of the cable arranging operation running trolley involved in the Chinese patent with the publication number CN114825176A. In order to facilitate height adjustment, the automatic compacting cable arranging device is installed at the front end of the vehicle body 6 through a lifting device 7. Specifically, the lifting end of the lifting device 7 is fixedly connected to the horizontal guide rail 1 to adjust the height of the horizontal guide rail 1. It should be noted that the automatic compacting cable arranging device can also be installed on other devices that can rotate circumferentially along the plane of the cable pit 18 and lift in the depth direction to perform cable arranging operations.

[0027] As Figure 2 shown, the traversing mechanism 2 is used to cooperate with the horizontal guide rail 1 to move along the horizontal guide rail 1, and includes a body 201, a belt pulley 202, a second transmission belt 203, a first rubber wheel 204, a second rubber wheel 205, a pre-tightening spring group 206, and a horizontal driving motor 207. The horizontal driving motor 207 is fixedly installed on the body 201, and two first rubber wheels 204 are rotatably connected to the body 201. Belt pulleys 202 are provided on the output shaft of the horizontal driving motor 207 and the wheel shaft of the first rubber wheel 204, and the second transmission belt 203 is wound around the belt pulleys 202. The horizontal driving motor 207 drives the three belt pulleys 202 to rotate through the second transmission belt 203, and then drives the first rubber wheel 204 to rotate. Two second rubber wheels 205 are rotatably connected to a slider 208. The slider 208 is slidably arranged on the body 201, and a pre-tightening spring group 206 is arranged between the slider 208 and the body 201. The distance between the first rubber wheel 204 and the second rubber wheel 205 is controlled by the pre-tightening spring group 206 so that the two are attached to the grooves on both sides of the horizontal guide rail 1. The first rubber wheel 204 constitutes the driving wheel, while the second rubber wheel 205 is the driven wheel. Driven by the horizontal driving motor 207, the entire traversing mechanism 2 can move back and forth on the horizontal guide rail 1.

[0028] As shown Figure 3 in the figure, the cable feeding device 3 is fixedly installed at the upper end of the machine body 201. The cable feeding device 3 includes a cable feeding base 301, a sleeve 302, a clamping head 303, a torque sensor 304 and a stress release motor 305. The stress release motor 305 is fixedly installed on the cable feeding base 301 in a vertical manner. The sleeve 302 is rotatably installed on the cable feeding base 301 through a slewing bearing 306. A gear ring 308 is provided on the barrel wall of the sleeve 302. The output end of the stress release motor 305 is installed with a torque sensor 304 and drives the sleeve 302 to rotate on the slewing bearing 306 through the meshing of a transmission gear 307 with the gear ring 308. There are three clamping heads 303, and they are equally distributed on the inner side of the barrel wall of the sleeve 302. In addition to the setting of the three clamping heads 303, the number of clamping heads 303 can be further increased, for example, four, and these clamping heads 303 are located on both sides of any diameter of the sleeve 302, so that both sides of the cable are evenly stressed.

[0029] The structure of the clamping head 303 includes a fixed seat 303a and a rotating arm 303b. A clamping roller 303c is rotatably arranged at the lower head end of the rotating arm 303b. The clamping roller 303c has a plurality of spaced roller surfaces, and a circumferential groove 303d is provided between the spaced roller surfaces. The fixed seat 303a is fixedly installed on the barrel wall of the sleeve 302. A clamping spring 303e is arranged between the fixed seat 303a and the upper end of the rotating arm 303b. The cable passes through the space between the head ends of each clamping head 303. The clamping roller 303c fits on the outer wall of the cable. The clamping spring 303e makes the clamping roller 303c closely adhere to the cable. The circumferential groove 303d of the clamping roller 303c can limit the circumferential self-rotation of the cable and release the axial sliding of the cable. During the cable arranging process, when the cable is transported in the sleeve 302, due to the internal stress of the cable, the cable will drive the sleeve 302 to rotate through the clamping head 303, and then it will be sensed by the torque sensor 304. When the internal stress detected by the torque sensor 304 is greater than the set threshold, the internal stress of the cable is released through the reverse rotation of the stress release motor 305, so that the cable is in a free tension state, which is beneficial to the subsequent cable compacting operation.

[0030] Please combine Figure 1 and 4 as shown in the figure, the swing arm 4 is connected to the lower end of the machine body 201. Specifically, an installation seat 8 is fixed at the lower end of the machine body 201. A swing motor 9 and a transition pulley 10 are installed on the installation seat 8. The end of the swing arm 4 is rotatably connected to the installation seat 8. The third transmission belt 11 is wound around the output shaft of the swing motor 9, the transition pulley 10 and the rotating connection shaft 17 at the end of the swing arm 4. The swing arm 4 is driven to rotate by the swing motor 9, so that the head end of the swing arm 4 swings to adjust its position.

[0031] At the position of the end of the swing arm 4 on the mounting base 8, a rotating motor 12 is also provided. The head end of the swing arm 4 is rotatably connected to a rotating shaft 13. A driven pulley 14 is arranged at the top end of the rotating shaft 13, and a driving pulley 15 is arranged on the driving shaft of the rotating motor 12. The first transmission belt 16 is wound around the driven pulley 14 and the driving pulley 15. By the operation of the rotating motor 12, the rotating shaft 13 rotates, and then the compacting mechanism 5 connected to the rotating shaft 13 rotates.

[0032] Please refer to Figures 5 to 9 As shown, the compacting mechanism 5 mainly includes three parts, namely a frame structure 51, a vertical pressing roller mechanism 52, and a horizontal squeezing roller mechanism 53.

[0033] The frame structure 51 includes a fixed frame 5101, a movable frame 5102, and a second lifting mechanism. Among them, the fixed frame 5101 is connected to the rotating shaft 13 at the head end of the swing arm 4, and the movable frame 5102 is connected to the fixed frame 5101 through the second lifting mechanism. When the fixed frame 5101 rotates, it drives the movable frame 5102 to rotate. The second lifting mechanism includes a lifting motor 5103, a guide post 5104, and a lead screw 5105. The lifting motor 5103 is fixedly installed on the fixed frame 5101. The lead screw 5105 is vertically arranged and is driven by the lifting motor 5103 to rotate. Guide posts 5104 are fixedly arranged on both sides of the lead screw 5105. A nut cooperating with the lead screw 5105 is arranged on the top plate of the movable frame 5102, and a guide sleeve 5106 is arranged on the top plate to cooperate with the guide post 5104 for guiding. The bottom ends of the lead screw 5105 and the guide post 5205 are both connected to the bottom beam of the fixed frame 5101. Vertical sliding rails 5107 are arranged on the inner walls on both sides of the movable frame 5102, and the two ends of the bottom beam of the fixed frame 5101 are slidably matched with the sliding rails 5107. By the action of the lifting motor 5103, the height of the movable frame 5102 can be controlled.

[0034] The vertical pressing roller mechanism 52 and the horizontal squeezing roller mechanism 53 are installed on the bottom plate of the movable frame 5102. The vertical pressing roller mechanism 52 includes a horizontally arranged pressing roller 5201 and a first lifting mechanism. The first lifting mechanism includes a basic base 5202. The basic base 5202 is fixed to the bottom plate of the movable frame 5102. The two sides of the basic base 5202 are slidably matched with a moving base 5203 through slide rails and sliders. A first driving device 5204 is connected between the basic base 5202 and the moving base 5203 to control the height of the moving base 5203. The first driving device 5204 can be an electric cylinder. A spring 5206 with a guide post 5205 is connected to the lower end of the moving base 5203. The lower end of the spring 5206 is connected to a mounting bottom plate 5207. The pressing roller 5201 is rotatably connected to the mounting bottom plate 5207, and its axial direction is horizontally arranged. The spring 5206 can ensure that the vertical pressing roller mechanism 52 has a certain pressing force and fine-tuning ability during operation.

[0035] The horizontal squeezing roller mechanism 53 is located in front of one end of the pressing roller 5201. The horizontal squeezing roller mechanism 53 includes a vertically arranged squeezing roller pair 5301 and a translation mechanism. The translation mechanism includes a base 5302, a driving motor 5303, driving gears 5304, guide rails 5305 and a suspension bottom plate 5306. The base 5302 is fixedly installed on the bottom plate of the movable frame 5102. The driving motor 5303 is a bidirectional motor, which is fixedly installed in the middle of the base 5302. Driving shafts on both sides of the bidirectional motor are respectively installed with driving gears 5304. Guide members 5307 are symmetrically and fixedly connected to both sides of the base 5302 where the bidirectional motor is located. The guide members 5307 are provided with horizontally arranged guide grooves 5307a, and guide pins 5307b are provided on both sides of the guide grooves 5307a. The guide rails 5305 are slidably arranged in the guide grooves 5307a. Chute grooves 5305a are opened on both sides of the guide rails 5305, and the guide pins 5307b extend into the chute grooves 5305a to form a sliding fit. A rack 5305b is provided on the top surface of the guide rails 5305, and the rack 5305b meshes with the driving gears 5304. Thus, when the bidirectional motor works, the guide rails 5305 will be driven by the rotation of the driving gears 5304 to move under the guidance of the guide grooves 5307a, and its moving direction is parallel to the axial direction of the pressing roller 5201.

[0036] Both ends of the guide rails 5305 extend out from both ends of the guide members 5307 and are fixedly connected to both sides of the suspension bottom plate 5306. The suspension bottom plate 5306 is simultaneously connected to the two guide members 5307. In addition, in order to improve the stability of the movement of the guide rails 5305, a guiding body 5306a is provided on the top surface of the suspension bottom plate 5306, and the guiding body 5306a is in sliding fit with the protrusions on the bottom surface of the guide members 5307, which better supports the left - right movement of the guide rails 5305. A pair of squeezing roller pairs 5301 are arranged on the suspension bottom plate 5306. The roller shafts of the squeezing roller pairs 5301 are vertically arranged and connected to the suspension bottom plate 5306. The cable output by the cable feeding device 3 passes by the side of the squeezing roller pairs 5301 and is located below the pressing roller 5201.

[0037] In addition, a visual detection device is also installed on the bottom plate of the movable frame 5102, which is used to detect the arrangement of the cables.

[0038] Next, the working mode of the present invention will be described by taking the cable arranging operation of the cable arranging trolley equipped with the automatic compacting cable arranging device of this embodiment.

[0039] Please refer to Figure 10 As shown, lower the cable arranging trolley to the bottom of the cable pit 18. The cable 20 passes through the cable feeding device 3, passes by the side of the squeezing roller pairs 5301 and is located below the pressing roller 5201. The cable 20 falls to the ground, and the cable arranging operation starts. This embodiment will explain the cable arranging operation from the inside out: The cable arranging trolley walks around the cable pool 18 at a certain radius. The electric control system realizes the cable arranging work according to the action logic. The basic process is as follows: 1) The cable 20 is conveyed from the top of the cable pool 18 at a certain speed and first enters the cable feeding device 3. Three clamping heads 303 clamp the cable 20, and the torque sensor 304 detects the tension of the cable 20 in real time. When the tension value is greater than the threshold, the stress release motor 305 works, and the cable 20 is clamped by the clamping head 303 and rotated in the direction of decreasing tension, aiming to make the downward conveyed cable in a smooth natural state and prevent the subsequent pressure roller 5201 and extrusion roller pair 5301 from warping and scattering due to the cable tension during operation.

[0040] 2) As the cable arranging operation progresses, the cable is arranged from the inside to the outside, and the operation radius becomes larger and larger. Therefore, the traversing mechanism 2 translates on the transverse guide rail 1 according to the operation radius, aiming to realize the adjustment of the cable feeding device 3 and the compacting mechanism 5 in the radial direction of the cable pool 18.

[0041] 3) The setting of the swing arm 4 can, on the one hand, expand the working radius of the cable arranging device. Especially when approaching the inner wall (outer wall) of the cable pool 18, the position of the compacting mechanism 5 is controlled by the swing of the swing arm 4 to avoid collision with the wall of the cable pool 18 and prevent collision. On the other hand, in cooperation with the rotation of the rotating shaft 13, when the cable arranging direction changes from inside to outside and from inside to outside, the compacting mechanism 5 can be adjusted by 180 degrees in phase to adapt to the adjustment of reverse cable arranging work.

[0042] 4) Drive the lead screw 5105 to adjust the height of the movable frame 5102 according to the height of the cable 20 or the operation depth, so that the extrusion roller pair 5301 will not collide with the lower-layer cable 20 or the bottom of the cable pool 18.

[0043] 5) The bidirectional motor and the electric cylinder work to make the extrusion roller pair 5301 approach the pressure roller 5201 to make the cable 20 closely adhere to the horizontally arranged cable 20 of the same layer, and at the same time, the downward pressure of the pressure roller 5201 makes the cable 20 closely adhere to the longitudinally arranged cable 20 of the lower layer. The visual detection device 19 detects the arrangement condition of the cable 20.

[0044] 6) Realize the cable arranging operation layer by layer in the cable pool 18.
