DETAILED DESCRIPTION

[0017] 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.

[0018] like Figures 1 to 4 As shown, a hydraulic cable pay-out device comprises a pay-out mechanism 8, a straightening mechanism 9 and a casing mechanism 10 which are arranged in sequence from top to bottom.

[0019] The unwinding mechanism 8 comprises a support roller 19 and a driving assembly for driving the support roller 19 to rotate, wherein the support roller 19 is used to support the hydraulic cable in a coiled state, and the hydraulic cable can be unwound during the rotation of the support roller 19.

[0020] The straightening mechanism 9 comprises an extension rod 24 and an igniter 27 which are arranged up and down. The extension rod 24 is provided with a through hole 25 for the untied hydraulic cable to pass through. The igniter 27 is used to heat the end of the hydraulic cable.

[0021] The casing mechanism 10 includes a mounting seat 29, a base plate 31 rotatably connected to the mounting seat 29, and a driver 39 for driving the base plate 31 to move, wherein a plurality of soft clamping rings 33 for clamping the cable protection tube are arranged from top to bottom on the base plate 31, and the hydraulic cable can enter downward into the cable protection tube after passing through the straightening mechanism 9.

[0022] During construction, the coiled hydraulic cable is firstly put on the support roller 19, and then the movable end of the hydraulic cable is pulled out and passed through the through hole 25 on the extension rod 24. Then, the movable end of the hydraulic cable is heated by the igniter 27 to melt a small part of the insulating skin of the movable end. After cooling, the sharp edge of the insulating skin of the movable end can be eliminated. In order to ensure that the insulating skin of the movable end can be evenly heated and avoid the deviation of the movable end causing the flame of the igniter 27 to be unable to contact the insulating skin, the igniter 27 can have two horizontally distributed nozzles 28. Subsequently, the support roller 19 is driven to rotate by the driving assembly. During the rotation of the support roller 19, the hydraulic cable is unwound from the coiled state, and the movable end moves downward continuously. When it is necessary to add a cable protection tube to the hydraulic cable, the cable protection tube can be placed in the casing mechanism 10 in advance, and the cable protection tube can be clamped by the soft clamping ring 33. At this time, the cable protection tube is in a state perpendicular to the ground and is located below the nozzle 28. During the downward movement of the movable end of the hydraulic cable, it can enter the cable protection tube. Because the sharp edge of the insulating skin of the movable end has been eliminated, the movable end can move more smoothly in the cable protection tube and finally pass through the cable protection tube. At this time, the cable protection tube has been sleeved on the hydraulic cable. In order to further ensure that the movable end can pass through the cable protection tube smoothly, the sleeve mechanism 10 is also provided with a driver 39, which can drive the substrate 31 to reciprocate, and then the substrate 31 drives the soft clamping ring 33 and the cable protection tube to reciprocate synchronously. In this way, the cable protection tube and the movable end of the hydraulic cable can be relatively displaced. Even if the movable end is stuck in the cable protection tube, it can be quickly freed and then pass through the cable protection tube smoothly. After the movable end of the hydraulic cable passes through a certain length from the lower end of the cable protection tube, the hydraulic cable can be cut off at a position between the igniter 27 and the extension rod 24. The new movable end formed after the cut is located above the igniter 27. In the subsequent process, the igniter 27 can be reused to process the movable end. The cut hydraulic cable and the cable protection tube can be removed together and then used for construction. On the other hand, when the movable end of the hydraulic cable passes through the lower end of the cable protection tube for a certain length, the hydraulic cable can be dragged manually to continue moving, so that the cable protection tube is only covered on part of the hydraulic cable, thereby meeting the construction needs of different positions.

[0023] The present invention can unwind the hydraulic cable from a coiled state, that is, realize the laying out of the hydraulic cable, and during the laying out process, the cable protection tube can be directly sleeved on the hydraulic cable without additional manual operation, thereby improving construction efficiency.

[0024] It should also be noted that the cable protection tube can be a heat shrink tube, corrugated tube or metal tube, which is commonly used in the construction process of hydraulic cables. The length can be determined according to actual needs and will not be repeated here. If the cable protection tube adopts a heat shrink tube or a metal tube, the hydraulic cable is not easy to get stuck when moving inside the cable protection tube, and there is no need to use an igniter 27 to heat the movable end, and there is no need to drive the substrate 31 to reciprocate. If the cable protection tube adopts a corrugated tube, the hydraulic cable is easy to get stuck. At this time, it is necessary to use an igniter 27 to heat the movable end to eliminate the sharp edge of the insulation skin, and drive the substrate 31 to reciprocate to get the hydraulic cable out of trouble. The igniter 27 is a prior art and can adopt a structure similar to a lighter. In addition, the igniter 27 only needs to slightly heat the insulation skin to eliminate the sharp edges around the insulation skin of the movable end when the hydraulic cable is cut off. There is no need to heat the insulation skin for a long time to avoid damaging the hydraulic cable.

[0025] Furthermore, the device includes a base 1, on which a mounting plate 3 is vertically fixedly arranged, a straightening mechanism 9 and a sleeve mechanism 10 are arranged on the mounting plate 3 and distributed up and down, a support plate 7 parallel to the base 1 is fixedly connected to the top of the mounting plate 3, and a wire-releasing mechanism 8 is arranged on the support plate 7. The base 1 and the support plate 7 can be connected by at least one support column 4, so as to ensure the stability of the support plate 7 and the wire-releasing mechanism 8. If at least two support columns 4 are provided, a raw material storage trough 6 extending up and down can be provided on one of the support columns 4 for temporarily storing spare cable protection tubes, and a baffle 5 is provided at the lower part of the raw material storage trough 6 to constrain the cable protection tube in the raw material storage trough 6. Similarly, at least one finished product storage trough 2 can be fixedly arranged on the base 1, and the cut hydraulic cable and the cable protection tube can be placed as finished products in the finished product storage trough 2 as a whole, so as to facilitate access during the construction process.

[0026] The specific structure of the wire-releasing mechanism 8 is as follows: the wire-releasing mechanism 8 comprises two sliding blocks 15 slidably arranged on the support plate 7, a vertical plate 16 is vertically fixedly arranged on the sliding block 15, a rotating shaft 17 is rotatably penetrated on the vertical plate 16, and a plug hole 21 extending along the axial direction is respectively provided at both ends of the support roller 19, and the rotating shaft 17 can be correspondingly inserted into the plug hole 21. After the coiled hydraulic cable is sleeved on the support roller 19, the support roller 19 is moved between the two vertical plates 16, and then the two sliding blocks 15 are driven to move toward each other until the two rotating shafts 17 are correspondingly inserted into the plug holes 21 at both ends of the support roller 19, so that the two vertical plates 16 can be used to support the support roller 19 and the coiled hydraulic cable, and then the driving assembly can be used to drive one of the rotating shafts 17 to rotate, and the rotating shaft 17 drives the support roller 19 to rotate synchronously, so as to untie the coiled hydraulic cable.

[0027] The specific structure of the driving assembly is as follows: the driving assembly includes a driving motor 23 fixedly connected to one of the sliding blocks 15, and the driving motor 23 drives the rotating shaft 17 connected to the sliding block 15 through a transmission belt 22. The driving assembly is arranged on one of the sliding blocks 15, and even if the sliding block 15 moves, the driving assembly can drive the rotating shaft 17 on the vertical plate 16 connected to the sliding block 15, thereby ensuring that the supporting roller 19 can be driven to rotate.

[0028] In order to facilitate driving the two sliding blocks 15 and ensure that the rotating shaft 17 can be correspondingly inserted into the sockets 21 at both ends of the support roller 19, the wire release mechanism 8 includes two relatively arranged fixed blocks 11, and a lead screw 13 is rotatably connected between the two fixed blocks 11, and the lead screw 13 passes through the two sliding blocks 15. One end of the lead screw 13 is connected to an adjustment motor 14 for driving the lead screw 13 to rotate, and the sliding block 15 can be driven to slide during the rotation of the lead screw 13. Based on this structure, after the construction personnel put the coiled hydraulic cable on the support roller 19, they can manually lift the support roller 19 and move it between the two vertical plates 16, and then use the adjustment motor 14 to drive the lead screw 13 to rotate. During the rotation of the lead screw 13, the two sliding blocks 15 are driven to move toward each other, and the two rotating shafts 17 are driven to move toward each other. During the movement of the rotating shaft 17, the construction personnel can fine-tune the position of the support roller 19 to ensure that the socket 21 is aligned with the rotating shaft 17, so as to ensure that the rotating shaft 17 can be smoothly inserted into the socket 21. It should also be noted that, because the lead screw 13 needs to be able to drive the two sliding blocks 15 to move toward each other, the lead screw 13 needs to be set as a bidirectional lead screw, which belongs to conventional technology and will not be described in detail here. At least one guide rod 12 can be connected between the two fixed blocks 11, and the guide rod 12 passes through the two sliding blocks 15. The guide rod 12 can limit the sliding direction of the sliding blocks 15, thereby ensuring that the lead screw 13 can smoothly drive the two sliding blocks 15 to slide.

[0029] Although the rotating shaft 17 can drive the support roller 19 to rotate through the friction between the inner wall of the socket 21 during the rotation process, there is a possibility that the support roller 19 cannot rotate due to slipping. In order to avoid this problem, the socket 21 is connected with at least one through slot 20 that penetrates the side wall of the support roller 19, and the rotating shaft 17 is fixedly connected with at least one limit rod 18. When the rotating shaft 17 is inserted into the socket 21, the limit rod 18 can extend from the through slot 20 and limit the coiled hydraulic cable. Through the cooperation of the limit rod 18 and the through slot 20, the limit rod 18 can drive the support roller 19 to rotate during the rotation of the rotating shaft 17, thereby ensuring that the support roller 19 can be driven to rotate smoothly. On the other hand, the limit rods 18 on the two rotating shafts 17 can also limit the coiled hydraulic cable on the support roller 19, thereby improving the stability of the line release process.

[0030] Considering that the coiled hydraulic cable will be in a bent state when it is unwound, the present invention provides a straightening mechanism 9 for straightening the bent hydraulic cable. In the straightening mechanism 9, by providing a through hole 25 on the extension rod 24 and passing the hydraulic cable through the through hole 25, the through hole 25 can be used to preliminarily straighten the hydraulic cable. A heating module can also be provided on the extension rod 24. When the hydraulic cable passes through the through hole 25, the heating module is used to heat it, which can improve the straightening effect. The heating module can include a heating element embedded in the extension rod 24, which generates heat when powered on. The arrangement method and the power-on method of the heating element are both mature existing technologies and will not be repeated here.

[0031] In order to further improve the straightening effect and enable the hydraulic cable to pass through the cable protection tube smoothly, the straightening mechanism 9 includes at least two groups of rollers 26 arranged in sequence from top to bottom, and the number of rollers 26 in each group is two. A straightening channel for the hydraulic cable to pass through is formed between the two rollers 26 in the same group, and all rollers 26 are located between the extension rod 24 and the igniter 27. When the hydraulic cable passes through the straightening channel, it can be squeezed by the rollers 26, so as to be further straightened, thereby achieving the purpose of improving the straightening effect. Further, a straightening motor can be configured for each roller 26, and the roller 26 is driven by the straightening motor to rotate. The actively rotating roller 26 can better squeeze the hydraulic cable, and the straightening effect is better. On the other hand, the actively rotating roller 26 can also pull the hydraulic cable and convey the hydraulic cable downward, so as to cooperate with the drive assembly to more efficiently untie the hydraulic cable from the coiled state. Obviously, the rotation directions of the two rollers 26 in the same group should be opposite. It should also be noted that before starting to lay out the cable, it is necessary to manually pass the movable end of the hydraulic cable through the through hole 25. On the basis of setting the roller 26, it is also necessary to manually pass the movable end through the straightening channel.

[0032] like Figure 5As shown, the specific connection method between the substrate 31 and the mounting seat 29 is as follows: the mounting seat 29 is fixedly connected with two connecting blocks 35, the lower end of the substrate 31 is located between the two connecting blocks 35 and is rotatably connected to the connecting block 35 through a connecting shaft 36, and the mounting seat 29 is also provided with a receiving groove 30 extending up and down, a part of the upper end of the substrate 31 extends into the receiving groove 30 and is connected to the bottom of the receiving groove 30 through a plurality of springs 37, and the substrate 31 is connected to the soft clamping ring 33 through at least one connecting column 32. Based on this connection method, the driver 39 can drive the substrate 31 to rotate around the connecting shaft 36 and stretch the spring 37. After the driver 39 is reset, the spring 37 can pull the substrate 31 to reset, and repeat the process. The substrate 31 can reciprocate and drive the soft clamping ring 33 and the cable protection tube to move synchronously, thereby ensuring that the hydraulic cable can pass through the cable protection tube smoothly. On this basis, the driver 39 can be set as a conventional linear driver such as a cylinder, thereby pushing the substrate 31 to rotate around the connecting shaft 36 during the elongation process.

[0033] The specific configuration of the driver 39 is as follows: a blind hole 38 is provided at the bottom of the receiving groove 30, the driver 39 is disposed in the blind hole 38, and the output end of the driver 39 faces the base plate 31. If the driver 39 is configured as a cylinder, the piston rod of the cylinder faces the base plate 31.

[0034] like Figure 6 As shown, considering that if the cable protection tube uses a heat shrink tube, the soft clamping ring 33 cannot exert too much pressure on the heat shrink tube, otherwise it will cause the heat shrink tube to deform, and then may cause the hydraulic cable to get stuck in the heat shrink tube. In order to avoid this situation, a plurality of support plates 40 for supporting the cable protection tube are fixedly connected to the inner wall of a soft clamping ring 33 located at the bottom. By setting the support plate 40, soft cable protection tubes such as heat shrink tubes and corrugated tubes can be supported, ensuring the stability of the cable protection tube while avoiding the deformation of the cable protection tube caused by excessive clamping force of the soft clamping ring 33. On the other hand, on the basis of setting the support plate 40, a distance is left between the lower end of the cable protection tube and the base so that the movable end of the hydraulic cable can smoothly pass through the cable protection tube. On this basis, the soft clamping ring 33 can be made of rubber material, and an incision 34 is opened to facilitate the placement of the cable protection tube in the soft clamping ring 33, and the cable protection tube is clamped by the soft clamping ring 33.

[0035] A method for laying out a hydraulic cable is based on the above-mentioned hydraulic cable laying out device, and the method includes S1 to S6.

[0036] S1. Sleeve the coiled hydraulic cable on the support roller 19 , and pass the movable end of the hydraulic cable through the through hole 25 .

[0037] S2. Place the cable protection tube below the igniter 27 and clamp the cable protection tube using the soft clamping ring 33.

[0038] S3, driving the support roller 19 to rotate and unwind the hydraulic cable.

[0039] S4. When the movable end of the hydraulic cable passes through the igniter 27, the movable end of the hydraulic cable is heated by the igniter 27 to eliminate the sharp edge formed on the surrounding side of the insulating skin of the movable end when the hydraulic cable is cut. Specifically, after the insulating skin of the movable end is heated and melted by the igniter 27, its end face will become an arc surface during the natural cooling process, and no longer have a sharp edge.

[0040] S5. After the movable end of the hydraulic cable enters the cable protection tube, the driver 39 is used to drive the base plate 31 to move, and the base plate 31 drives the soft clamping ring 33 and the cable protection tube to move. Specifically, the driver 39 first drives the base plate 31 to rotate around the connecting shaft 36. During the process, the base plate 31 stretches the spring 37. When the driver 39 is reset, the spring 37 pulls the base plate 31 to reset. The process is repeated to realize the reciprocating motion of the base plate 31.

[0041] S6. After the active end of the hydraulic cable passes through the cable protection tube, the support roller 19 is stopped from rotating, and the hydraulic cable is cut off above the igniter 27. It should also be noted that the length of the cut hydraulic cable exceeds the length of the cable protection tube, so as to facilitate the connection of equipment in the subsequent construction process. In addition, the heated part of the active end of the hydraulic cable can be cut off in the subsequent construction process.

[0042] Finally, the present invention is applicable to conventional hydraulic cables, such as YSPT hydraulic observation cables, etc. For hydraulic cables that do not require an additional cable protection tube, the present invention can also be used for laying out the cables without placing a cable protection tube in the casing mechanism 10 .

[0043] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
