[0044] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the Figure 1 The left and right directions are consistent.

[0046] The cable laying positioning device in this embodiment can be applied to the laying of underground cables, which can significantly improve the laying efficiency of underground cables, reduce unnecessary labor input, and also facilitate the subsequent inspection and maintenance of underground cables.

[0047] like Figures 1 to 4 As shown, this embodiment provides a cable laying positioning device, including a frame 11 with wheels 16, a winding shaft 12 rotatably mounted on the frame 11, a base 13 mounted on the frame 11, a wire clamp 14 with a plurality of wire clamping seats 141, and a pusher 15.

[0048] The frame 11 is movable by the wheels 16. During laying, the frame 11 can move along the extension direction of the cable trench, thereby achieving laying of the cable 23. Compared with manually dragging or pushing a reel with the cable 23, the laying efficiency is higher.

[0049] The reel 12 releases the cable 23 by rotating. After the cable 23 to be laid is produced, it is wound around the reel 12. The reel 12 with the wound cable 23 is then mounted on the frame 11. During the movement of the frame 11, the reel 12 rotates to release the cable 23 and lay it along the cable trench. There are several reels 12, and at least one reel 12. When multiple and / or different types of cables 23 need to be laid, multiple reels 12 are provided, each reel 12 being wound with a different cable 23, enabling simultaneous laying of different cables 23.

[0050] The base 13 has a clamp feeding channel 131 and a wire feeding channel 132 communicated with the clamp feeding channel 131. The wire feeding channel 132 is used to feed the cable 23, and the clamp feeding channel 131 is used to feed the wire clamp 14.

[0051] The cable clamp 14 has a plurality of clamping seats 141. Each clamping seat 141 is provided with a clamping groove 142. The cable clamp 14 is used to position the cable 23. The cable clamp 14 can be delivered from the clamping channel 131 to the cable feeding channel 132. After entering the cable feeding channel 132, the cable clamp 14 can be respectively clamped into different clamping grooves 142, so that different cables 23 are not piled up together, thereby preventing the underground cables 23 from becoming messy or entangled, and facilitating subsequent inspection and maintenance of the cables 23.

[0052] The pusher 15 is used to push the clamp 14 in the clamp feeding channel 131 to move so that each clamp seat 141 is respectively sleeved on each cable 23 in the wire feeding channel 132 through the clamping groove 142. Each clamp seat 141 of the clamp 14 enters the wire feeding channel 132 at the same time, and the clamping groove 142 on each clamp seat 141 is respectively sleeved on a different cable 23. The pusher 15 is installed on the base 13. The pusher 15 can realize automatic transportation of the clamp 14. After the pusher 15 pushes the clamp 14 from the clamp feeding channel 131 to the wire feeding channel 132, the clamp seat 141 of the clamp 14 is sleeved on the cable 23 using the clamping groove 142. Each cable 23 corresponds to a clamping groove 142, thereby realizing the positioning of each cable 23 and preventing the cables 23 from piling up or getting tangled together. After each cable 23 is clamped in a different clamping groove 142 of the clamp 14, as the rack 11 moves, the cable laying and positioning device transports a clamp 14 every time it moves a certain distance to achieve different positioning of the cables 23. After each clamp 14 completes the positioning of the cable 23, it is directly laid in the wire groove, that is, along the extension direction of the wire groove, there is a clamp 14 every time it moves a certain distance to sort and distinguish each cable 23, so that the cables 23 will not be confused after being laid along the wire groove for a long distance. When the cables 23 are subsequently inspected and maintained, it is also convenient to quickly find the corresponding cable 23 and disassemble and replace it.

[0053] In one embodiment, the pusher 15 includes a first motor mounted on the base 13, a first sprocket mounted on the base 13 and in transmission connection with the first motor, a second sprocket mounted on the base 13 and spaced apart from the first sprocket, a conveyor chain 151 sleeved over the first and second sprockets, and a pusher 152. The first motor is not shown. The conveyor chain 151 is provided with a plurality of push holes spaced apart along the path of the conveyor chain 151. The first motor drives the first sprocket to rotate, thereby moving the conveyor chain 151.

[0054] The wire clamp 14 also has a support base 143; the wire clamp bases 141 are spaced apart on the support base 143. The support base 143 is provided with an insertion rod 149, which is used to be inserted into any push hole. When the conveyor chain 151 moves, it can drive the entire wire clamp 14 to move, so that the wire clamp 14 can enter the wire feeding channel 132 from the clamp feeding channel 131. The pusher 152 has a pushing portion 153 for pushing the support base 143 toward the conveyor chain 151 so that the insertion rod 149 is engaged with the push hole. The pushing portion 153 moves in a straight line direction, and the moving direction of the pushing portion 153 is the radial direction of the first sprocket or the second sprocket, that is, the moving direction of the pushing portion 153 is perpendicular to the straight line moving direction of the conveying chain 151. By pushing the wire clamp 14 through the pushing portion 153, the insertion rod 149 of the wire clamp 14 can be inserted into the pushing hole, and then the wire clamp 14 is driven from the clamping channel 131 into the wire feeding channel 132 through the movement of the conveying chain 151.

[0055] Alternatively, the pusher 152 may be an electric telescopic rod, a pneumatic cylinder, or a hydraulic cylinder, and the wire gripper 14 may be pushed onto the conveyor chain 151 by controlling the automatic activation of the electric telescopic rod, the pneumatic cylinder, or the hydraulic cylinder. Furthermore, it is understood that the pusher 152 may also include a push rod and a first spring. The elastic force of the first spring pushes the push rod, which pushes the wire gripper 14 to push the wire gripper 14 onto the conveyor chain 151.

[0056] Furthermore, the base 13 also has a material channel 133 and a push channel 134. A pusher 152 is mounted on the push channel 134. The material channel 133 and the clamp feeding channel 131 are spaced apart and connected to the push channel 134. Specifically, the material channel 133 and the clamp feeding channel 131 extend from top to bottom, with the lower ends of the material channel 133 and the lower ends of the clamp feeding channel 131 connected to the push channel 134. The upper end of the material channel 133 is located on the upper surface of the base 13 and connected to the exterior of the base 13. Multiple wire clamps 14 are stacked from top to bottom within the material channel 133.

[0057] A stopper 154 is provided on the pushing portion 153. When the pushing portion 153 passes through the connection between the material channel 133 and the pushing channel 134 and approaches the conveying chain 151, the stopper 154 blocks the connection between the material channel 133 and the pushing channel 134 to prevent the wire clamp 14 from falling into the pushing channel 134. When the pushing portion 153 passes through the connection between the material channel 133 and the pushing channel 134 and approaches the conveying chain 151, the stopper 154 detaches from the connection between the material channel 133 and the pushing channel 134, and the wire clamp 14 falls into the pushing channel 134 under the action of gravity.

The current laying equipment cannot avoid interference between the material channel 133 and the wire feeding channel 132, so generally only one of the channels can be set up, and the function that the other channel can achieve can only be achieved through manual assistance. The present application can avoid interference between the material channel 133 and the wire feeding channel 132. The material channel 133 is located in the middle area of ​​the base 13, and the material channel 133 extends from top to bottom. The channel mouth of the material channel 133 is located on the upper surface of the base 13, and the push channel 134 is located below the material channel 133. The push channel 134 extends from front to back, and the clamping channel 131 extends from top to bottom. The lower end of the clamping channel 131 is connected to the push channel 134, and the upper end of the clamping channel 131 is connected to the wire feeding channel 132. The wire feeding channel 132 extends from front to back through the base 13. Specifically, in this embodiment, the width direction of the cable 23 groove is the left and right direction. In order to enable the wire clamp 14 to vertically enter the pushing channel 134 from top to bottom along the material channel 133, then horizontally enter the clamp feeding channel 131 from front to back along the pushing channel 134, and then enter the wire feeding channel 132 from bottom to top along the clamp feeding channel 131. The wire feeding channel 132 has a first channel section 135, a second channel section 136, and a third channel section 137. The first channel section 135, the second channel section 136, and the third channel section 137 are connected at once. The first channel section 135 is located at the front end of the base 13 and extends horizontally from front to back. The second channel section 136 extends horizontally from left to right. The third channel section 137 is located at the rear end of the base 13 and extends horizontally from front to back. The connection between the first channel section 135 and the second channel section 136 and the connection between the second channel section 136 and the third channel section 137 are both provided with a second guide wheel 18. Through the second guide wheel 18, the cable 23 passes through the first channel section 135, the second channel section 136, and the third channel section 137 in sequence. The cable 23 enters the first channel section 135 horizontally from front to back, and finally the cable 23 and the clamp 14 are horizontally moved out of the third channel section 137 from front to back. In this way, interference between the material channel 133 and the wire feeding channel 132 is avoided, so that the cable 23 and the clamp 14 can be assembled together in the wire feeding channel 132, thereby realizing the assembly and transportation of the cable 23 and the clamp 14.

[0059] In one embodiment, the support base 143 has a first mounting end 144 and a second mounting end 145. The first mounting end 144 is the upper end of the support base 143, and the second mounting end 145 is the lower end of the support base 143. The wire clamping bases 141 are spaced apart at the first mounting end 144. The cross-section of the second mounting end 145 gradually decreases in a direction away from the first mounting end 144. The cross-section of the second mounting end 145 in the horizontal plane gradually decreases from top to bottom. The second mounting end 145 is pointed, which facilitates the insertion of the support base 143 into the soil at the bottom of the cable trench.

[0060] In one embodiment, the inner wall of the wire feeding channel 132 is provided with an arcuate groove 138 for positioning the cable 23. When the cable 23 is released from the reel 12 and passes through the wire feeding channel 132, the outer circumferential side surface of the cable 23 abuts against the inner wall of the arcuate groove 138, thereby positioning the cable 23. When the wire clamping seat 141 abuts against the inner wall of the wire feeding channel 132, the cable 23 is clamped into the wire clamping groove 142 through the notch of the arcuate groove 138.

[0061] Optionally, the wire clamping groove 142 is arc-shaped, and the diameter of the wire clamping groove 142 and the diameter of the arc groove 138 are both equal to the diameter of the cable 23. The circumference of the arc groove 138 is less than half of the circumference of the cable 23. The circumference of the wire clamping groove 142 is greater than half of the circumference of the cable 23 and is less than the circumference of the cable 23. The wire clamping seat 141 is elastic, and the edge of the slot of the wire clamping groove 142 can be deformed, so that the size of the edge of the slot of the wire clamping groove 142 can change when subjected to external force, which facilitates the cable 23 to be inserted into the wire clamping groove 142, and also prevents the cable 23 from easily detaching after being inserted into the wire clamping groove 142.

[0062] Furthermore, the base 13 has a plurality of rollers 139, and arc grooves 138 are formed on the outer circumferential sides of the rollers 139. The rollers 139 are rotatably mounted on the base 13. The rollers 139 are circumferentially provided with annular grooves to form arc grooves 138. After the rollers 139 are rotatably mounted on the base 13, part of the rollers 139 are located in the wire feeding channel 132 so that the inner wall of the arc groove 138 rotated into the wire feeding channel 132 becomes the inner wall of the wire feeding channel 132, which can not only realize the positioning of the cable 23 but also improve the smoothness of the cable 23 transportation.

[0063] In one embodiment, the cable laying and positioning device further includes a digger 19 mounted on the frame 11; each reel 12 is located between the digger 19 and the base 13. The digger 19 is located at the front end of the frame 11 in the forward direction and can be used to dig a cable trench. The digger 19 can be a bucket of an excavator.

[0064] In one embodiment, the cable laying and positioning device further includes a puncher 20 and a compactor 21; both the puncher 20 and the compactor 21 are mounted on the frame 11. The puncher 20 and the compactor 21 are both located at the rear end of the excavator 19 frame 11 in the forward direction. The puncher 20 can punch holes in the bottom of the cable trench to facilitate insertion of the second mounting end 145 of the support base 143 into the bottom of the cable trench. After the cable clamp 14 is sleeved onto the plurality of cables 23 through the respective cable clamping grooves 142, the cable clamp 14 leaves the base 13 along with the cables 23, and then the compactor 21 pushes the second mounting end 145 of the support base 143 of the cable clamp 14 into the pre-punched hole in the bottom of the cable trench.

[0065] Optionally, the punch 20 includes a first cylinder and a rod 149 mounted on the piston of the first cylinder. Rod 149 has a pointed end, which is inserted into the bottom of the wire trench to punch a hole. The compactor 21 includes a second cylinder and a hammer mounted on the piston of the second cylinder. The hammer squeezes the wire clamp 14, pushing the second mounting end 145 of the support base 143 of the wire clamp 14 into the pre-punched hole.

[0066] In one embodiment, the cable laying and positioning device further comprises a resonance breaker which is mounted on the frame 11. The resonance breaker can break up the cement floor, making it easier for the excavator 19 to dig the cable trench.

[0067] In one embodiment, the cable laying and positioning device further includes a first wheel seat and a second wheel seat. Wheels 16 are rotatably mounted on each of the first and second wheel seats. The first and second wheel seats are spaced apart along the axial direction of the wheels 16 and are both slidably mounted on the frame 11 along the axial direction of the wheels 16. Specifically, the first and second wheel seats are slidably mounted on the frame 11 via guide rails. The distance between the first and second wheel seats is adjustable, and the frame 11 can be mounted on both sides of cable trenches of different widths and move along the extension direction of the cable trenches, thereby allowing the cable laying and positioning device to adapt to cable trenches of different widths.

[0068] Furthermore, the cable laying positioning device also includes a second motor mounted on the frame 11, and a first screw rod and a second screw rod both rotatably mounted on the frame 11; the first screw rod and the second screw rod are coaxially connected, and the threads of the first screw rod and the threads of the second screw rod are opposite; the second motor is drivingly connected to the first screw rod or the second screw rod; the first wheel seat is threadedly connected to the first screw rod, and the second wheel seat is threadedly connected to the second screw rod. The second motor can drive the first wheel seat and the second wheel seat toward or away from each other, thereby adjusting the distance between the first wheel seat and the second wheel seat.

[0069] Optionally, the wheel is located above the reel 12, and the reel 12 is detachably mounted. When laying the cable 23, the reel 12 is located in the cable trench, and along the forward direction of the frame 11, the reel 12 is located in front of the base 13, which facilitates the laying of the cable 23.

[0070] In one embodiment, a lifting frame 22 is provided on the frame 11, and a reel 12 is rotatably and detachably mounted on the lifting frame 22. When laying a cable 23, the reel 12 is lowered into the cable trench. When laying is completed or the cable 23 needs to be replaced, the reel 12 is raised above the cable trench so that a new cable 23 can be wound and laid.

[0071] Optionally, the base 13 is detachably mounted on the rack 11 , and when mounted on the rack 11 , the base 13 can slide up and down relative to the rack 11 , thereby adjusting the height at which the cables 23 are laid.

[0072] In one embodiment, a plurality of first guide wheels 17 are provided on the frame 11 or the lifting frame 22 . When the cable 23 is released from the winding reel 12 , the cable passes through the first guide wheels 17 and enters the cable feeding channel 132 on the base 13 .

[0073] In one embodiment, the wire clamp 14 further includes a first stop bar 146, a second stop bar 147, and a slider 148. The wire clamp seat 141 also has a first strip groove 1411, a second strip groove 1412, and a slide groove 1413. The first strip groove 1411 and the second strip groove 1412 both extend along a circular arc trajectory, and the slide groove 1413 is located between the first strip groove 1411 and the second strip groove 1412. The first strip groove 1411, the second strip groove 1412, and the slide groove 1413 are jointly arranged outside the wire clamp groove 142. The slide groove 1413 is located at the bottom of the wire clamp groove 142 and is connected to the wire clamp groove 142. One end of the first strip groove 1411 and one end of the second strip groove 1412 are evenly connected to the slide groove 1413, and the other end of the first strip groove 1411 and the other end of the second strip groove 1412 are both connected to the notch of the wire clamp groove 142. The first stop bar 146 is slidably arranged in the first strip groove 1411, the second stop bar 147 is slidably arranged in the first strip groove 1411, and the slider 148 is slidably arranged in the slider groove 1413 via the second spring. The cross-section of the slider 148 gradually decreases in the direction away from the notch of the clamping groove 142. When the cable 23 is clamped into the clamping groove 142 from the notch of the clamping groove 142, when the cable 23 abuts against the slider 148 at the bottom of the clamping groove 142 and squeezes the slider 148, the slider 148 compresses the second spring and pushes the first stop bar 146 and the second stop bar 147 to move, so that the first stop bar 146 and the second stop bar 147 extend into the notch of the clamping groove 142, thereby blocking the cable 23 and preventing the cable 23 from being easily disengaged. After the cable 23 is laid, the first stop bar 146 and the second stop bar 147 can also block the mud and sand filling the buried cable trench. Compared with the method of setting a sealing film at the groove of the wire clamping groove 142, the present application uses the first baffle 146 and the second baffle 147 to block the mud and sand filling the buried wire trench. The first baffle 146 and the second baffle 147 can also achieve the positioning of the cable 23. The first baffle 146 and the second baffle 147 abut and clamp the cable 23 together with the inner wall of the wire clamping groove 142 to prevent the cable 23 from escaping from the wire clamping groove 142.

[0074] Furthermore, the first stop bar 146 and the second stop bar 147 are flexible magnetic strips, and the first stop bar 146, the second stop bar 147 and the slider 148 are all magnetic. The end of the first stop bar 146 close to the slider 148 and the end of the second stop bar 147 close to the slider 148 are opposite to the magnetism of the slider 148. When the cable 23 is inserted into the wire clamping groove 142, the slider 148 is squeezed to slide in the direction away from the slot of the wire clamping groove 142, and the slider 148 is close to the first stop bar 146 and the second stop bar 147, so that the first stop bar 146 and the second stop bar 147 extend out to the slot of the wire clamping groove 142.

[0075] Optionally, each clamping seat 141 is provided with a label slot and a cover. The cover is rotatably mounted on the clamping seat 141, and a label with information of the cable 23 can be placed in the label slot. After the label is placed in the label slot, the cover rotates and covers the slot body of the label slot.

[0076] Furthermore, the wire clamp 14 also includes a cover. After the cable 23 is laid, the cover covers each wire clamp seat 141. After the wire trench is buried, the cover can protect each wire clamp seat 141.

[0077] In one embodiment, each clamping seat 141 can be detachably mounted on the support seat 143, which facilitates the maintenance of the cable 23 and also facilitates the replacement of different clamping seats 141, so that the clamping groove 142 of the clamping seat 141 can adapt to cables 23 of different diameters.

[0078] This embodiment further provides a method for laying a cable 23. Based on the above-mentioned cable laying positioning device, the method for laying a cable 23 includes the following steps:

[0079] S10: Arrange multiple cable clamps 14 in the clamp feeding channel 131, and secure one end of the cable 23 on each reel 12 in the underground cable trench. First, the reel 12 with the cable 23 to be laid is installed on the frame 11, and then one end of the cable 23 is secured in the underground cable trench.

[0080] S20: The frame 11 is driven to move along the extension direction of the underground cable trench while releasing the cable 23 so that the cable 23 passes through the cable feeding channel 132. The frame 11 moves along the extension direction of the cable trench using the wheels 16, and the cable 23 is released by rotating the winding shaft 12. The cable first passes through the cable feeding channel 132 and is laid in the cable trench.

[0081] S30 : Every time the rack 11 moves a certain distance, the winding shaft 12 releases the corresponding length of the cable 23 , and the released cable 23 first enters the wire feeding channel 132 . After the cable 23 enters the wire feeding channel 132, the pusher 15 is started to push the wire clamp 14 in the feeding channel 131 to move so that each wire clamp seat 141 is respectively sleeved on each cable 23 located in the wire feeding channel 132 through the wire clamping groove 142. After each wire clamp seat 141 is respectively sleeved on the cable 23 in different wire feeding channels 132 through the wire clamping groove 142, the assembly of the wire clamp 14 and each cable 23 is completed, so that each cable 23 is positioned by the wire clamp 14. After the wire clamp 14 and each cable 23 are assembled, the wire clamp 14 and each cable 23 are moved out of the wire clamp 14 and each cable 23 and into the wire trench, so that each wire clamp seat 141 and the cable 23 are laid in the underground wire trench from the wire feeding channel 132. Finally, the wire clamp 14 is fixed to the bottom of the wire trench through the support seat 143 to complete the laying of the cable 23.

[0082] Before laying, a trench can be dug using an excavator 19. If the ground is concrete, a resonance crusher can be used to break up the concrete before digging the soil. Before the support base 143 is fixed to the bottom of the trench, a hole is punched using a punch 20, and then a compactor 21 is used to press the second mounting end 145 of the support base 143 into the hole to achieve the positioning of the wire clamp 14.

[0083] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
