[0001] The invention relates to the technical field of cable laying, and in particular to an anti-twisting device and method for laying multiple cables in a narrow space of a deep well. Background Art

[0002] In recent years, the National Energy Administration has strongly supported and encouraged the development and application of intelligent technology and equipment for coal mines. Advanced and applicable technology and equipment such as large-section rapid excavation and anchoring systems, full-section excavation equipment for rock tunnels, and large-angle mine shield machines have been successfully applied underground, which has accelerated the construction speed. This has led to an increase in underground electricity projects in mines, and at the same time, it is necessary to increase transmission lines. Considering the requirements of safety regulations and the post-maintenance conditions of cable laying, the shaft of the auxiliary shaft of a general mine will give priority to the layout of multiple transmission cables. Because the auxiliary shaft undertakes the task of transporting personnel and materials for the entire mine, it is necessary to arrange corresponding supporting facilities such as hoisting cages, pedestrian ladders, and pipelines in the shaft. Under the objective condition that the cross-sectional area of ​​the shaft remains unchanged, the installation space reserved for cable laying is extremely small. And with the renewal of excavation and masonry technology and construction equipment, many ultra-deep shafts of kilometers have emerged. While the construction of mines is gradually developing in depth, the construction units have increasingly stringent requirements on the quality and progress of the project, and must strive to maximize profits in a short period of time, which requires the construction units to complete the construction tasks with high quality within the extreme construction period.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0019] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes an anti-twisting device for laying multiple cables in a narrow space in a deep well, including a hanging plate 2 for entering the wellbore 1 as a construction platform, a cable drum 3 and a wire rope 7, the cable drum 3 is hoisted on the hanging plate 2, and the wire rope 7 is used to be lowered synchronously with the cable 8, and also includes: a fixing card 4, which has a plurality of fixing cards 4, and the plurality of fixing cards 4 are arranged on the inner wall of the wellbore 1 at intervals, and the fixing card 4 has a through groove 4021 for limiting the wire rope 7 and the cable 8; a bundler 5, which is lifted and arranged on the hanging plate 2, and the bundler 5 has a accommodating area 902, and the accommodating area 902 is used to accommodate the wire rope 7 and the cable 8, and the bundler 5 is used to bundle the wire rope 7 and the cable 8 together.

[0022] In the above scheme, it should be noted that a lifting rod for manual handholding or mechanical arm holding is also provided on the bundler 5, and the lifting rod is used to control the lowering distance of the bundler 5 so as to complete the bundling work. The hanging plate 2 enters the wellbore 1 as a construction platform to provide an operating space for the laying of the cable 8. For example, in a kilometer-deep well, the hanging plate 2 can carry construction personnel and equipment to ensure that the laying work is carried out smoothly at different heights in the wellbore 1. The cable drum 3 is hoisted on the hanging plate 2 to facilitate the lowering operation of the cable 8. Cables 8 of different specifications can be coiled on the corresponding cable drum 3 and lowered in order according to the construction progress. The bundler 5 is lifted and set on the hanging plate 2, and has a accommodating area 902 for accommodating the wire rope 7 and the cable 8. During the lowering process of the cable 8, the bundler 5 can be adjusted with the lowering height of the cable 8, which is convenient for bundling the cable 8 and the wire rope 7 at different positions.

[0023] There are several fixing cards 4, which are arranged at intervals on the inner wall of the shaft 1. In the coal mine air intake shaft 1, the position and number of the fixing cards 4 are reasonably determined according to the number and weight of the cables 8 in the shaft 1 and the structural characteristics of the shaft 1. For example, the density of the fixing cards 4 can be appropriately increased in the key parts of the shaft 1 and the areas where the cables 8 are prone to displacement.

[0024] The fixing card 4 has a through groove 4021 for limiting the position of the steel wire rope 7 and the cable 8. When the cable 8 and the steel wire rope 7 are lowered, they can be embedded in the through groove 4021, thereby limiting their lateral movement, ensuring that the cable 8 and the steel wire rope 7 maintain the correct position in the wellbore 1, avoiding entanglement with each other or collision with the inner wall of the wellbore 1, and improving the accuracy and safety of laying.

[0025] By limiting the position of the steel wire rope 7 and the cable 8 by the fixing card 4 and bundling them with the bundling device 5, the cable 8 can be effectively prevented from twisting, winding and displacement during the laying process, ensuring the neatness and standardization of the laying of the cable 8 and improving the laying quality. Preventing the cable 8 from twisting and winding can prevent the cable 8 from being damaged due to excessive twisting, reducing safety hazards. At the same time, the setting of the fixing card 4 and the bundling device 5 also ensures the stability of the cable 8 and the steel wire rope 7 in the shaft 1, preventing them from colliding with the inner wall of the shaft 1, and improving the safety during the construction process. Reasonable setting of the hanging tray 2, the cable tray 3 and the steel wire rope 7, and the coordinated use of the fixing card 4 and the bundling device 5 can make the laying process of the cable 8 more orderly and efficient. For example, by reasonably distributing the position of the cable tray 3 on the hanging tray 2, the adjustment time during the lowering process of the cable 8 can be reduced; through the fast bundling operation of the bundling device 5, the speed of laying the cable 8 can be accelerated.

[0026] Furthermore, the bundler 5 includes: a box body 501, which has a storage space 502; a winding drum 11, which is rotatably arranged in the storage space 502, and the winding drum 11 is wound with a bundling wire 13 for bundling the wire rope 7 and the cable 8; a conveying member, which is arranged on one side of the outlet end of the winding drum 11, and the conveying member is used to convey the bundling wire 13; a clamping member 9, which is rotatably arranged in the box body 501, and one end of the clamping member 9 extends out of the box body 501, and a accommodating area 902 is formed between the clamping member 9 located outside the box body 501 and the outer wall of the box body 501, and the bundling wire 13 moves along the clamping member 9 and is wound around the outer side of the cable 8 and the wire rope 7; a tightening member 12, which is rotatably arranged on the outer wall of the box body 501, and the tightening member 12 is used to tighten the two ends of the bundling wire 13 wound around the outer side of the cable 8 and the wire rope 7.

[0027] In the above scheme, the bundler 5 is a complex and ingeniously designed device, and its various components work closely together to achieve effective bundling of the wire rope 7 and the cable 8. First, there is the box body 501, which serves as the basic structure of the entire bundler 5 and has a storage space 502. This space provides an environment for the installation and operation of other components, while protecting the internal components from the complex environment of the wellbore 1 and ensuring the relative position of each component is stable. The winding drum 11 is rotatably arranged in the storage space 502, and the bundling wire 13 for bundling is wound on it. The bundling wire 13 can be flexibly released or retracted according to actual needs, providing a suitable length of bundling wire 13 for the bundling operation. The conveying member is located on the side of the outlet end of the winding drum 11, and is composed of a plurality of rotating pressure rollers 14. These pressure rollers 14 apply pressure to the bundling wire 13 to stably pull it out of the winding drum 11, ensuring that the bundling wire 13 has a suitable tension during the pulling process to avoid slack or winding problems. The clamping member 9 is rotatably arranged in the box body 501 and one end extends out of the box body 501. It is composed of a clamping rod 903 and a deflection driving member 6. The clamping rod 903 is symmetrically arranged and passes through the strip groove 503 of the box body 501. The deflection opening or closing can be achieved through the transmission of the deflection driving member 6. Its function is to form a accommodating area 902 and clamp the cable 8 and the wire rope 7. When performing bundling operations, first open the clamping rod 903 to allow the cable 8 and the wire rope 7 to enter the accommodating area 902, and then close the clamping rod 903 to clamp, thereby providing a stable foundation for subsequent bundling. The tightening member 12 is rotatably arranged on the outer wall of the box body 501, and is composed of a second driver 1202, a first driving gear 1201, a second driving gear 1203 and a T-shaped rod. The second driver 1202 drives the relevant gears to drive the T-shaped rod to rotate. The threading hole 1205 on the T-shaped rod is connected to the threading groove 901 of the clamping member 9, and the binding wire 13 passes through it. The tightening member 12 can tighten and knot the two ends of the binding wire 13 wound around the outside of the cable 8 and the wire rope 7 to ensure that the binding is firm, prevent the binding wire 13 from loosening, and ensure that the relative position of the cable 8 and the wire rope 7 is stable.

[0028] Furthermore, the box body 501 has a strip groove 503, and the clamping member 9 includes: a clamping rod 903, which has a plurality of clamping rods 903, which are symmetrically arranged, and each clamping rod 903 passes through the strip groove 503, and the rod body of the clamping rod 903 is rotatably arranged in the box body 501, and the clamping rod 903 has a threading groove 901, and the threading groove 901 is used to accommodate the binding wire 13; a deflection drive member 6, which is arranged in the box body 501, and the deflection drive member 6 is transmission-connected to the clamping rod 903, and the deflection drive member 6 is used to drive the clamping rod 903 to deflect open or close.

[0029] In the above solution, the strip groove 503 of the box body 501 is precisely matched with the clamping rod 903, providing a through passage for the clamping rod 903. The strip groove 503 limits the movement trajectory of the clamping rod 903, so that the clamping rod 903 can only deflect in the direction specified by the groove, which is the key basis for realizing the correct opening and closing action of the clamping rod 903.

[0030] The clamping rod 903 has multiple components and is arranged symmetrically. This symmetrical design is crucial because it can ensure that when the cable 8 and the wire rope 7 are clamped, the force is evenly distributed, effectively avoiding the displacement of the cable 8 or the wire rope 7 due to excessive force on one side. Each clamping rod 903 passes through the strip groove 503, and its rod body can rotate flexibly in the box body 501. At the same time, the clamping rod 903 also has a structure of a threading groove 901. The size of the threading groove 901 is carefully designed to ensure that the tying wire 13 can pass through it smoothly on the one hand, and to avoid the tying wire 13 from shaking due to being too loose on the other hand. The core function of the clamping rod 903 is to complete the opening and closing action under the drive of the deflection drive member 6, thereby forming or opening the accommodating area 902. When the clamping rod 903 is closed, it can provide a stable clamping force for the cable 8 and the steel wire rope 7, effectively ensuring that the cable 8 and the steel wire rope 7 will not be displaced during the bundling process, and the threading groove 901 can also guide the bundling wire 13.

[0031] Furthermore, the deflection drive member 6 includes: a first driver 604, which is arranged in the box body 501; a driving gear 603, which is arranged on the first driver 604; a first sector gear 602, which is arranged on a clamping rod 903, and the first sector gear 602 and the driving gear 603 are meshed; a second sector gear 601, which is arranged on another clamping rod 903, and the first sector gear 602 and the second sector gear 601 are meshed with each other. After the first sector gear 602 and the second sector gear 601 are meshed and rotated with each other, the clamping rod 903 is deflected along the strip groove 503 to open or close.

[0032] In the above solution, the first driver 604 is arranged in the box body 501 as the power of the entire deflection drive member 6. In practical applications, it is necessary to select a suitable first driver 604 according to the special environment and specific power requirements of the wellbore. Since the wellbore 1 environment may be humid and dusty, the first driver 604 is required to have the ability to adapt to the harsh environment, and also have a suitable torque and speed to ensure that the clamping rod 903 can be stably driven to open and close.

[0033] The driving gear 603 is arranged on the first driver 604 and is closely connected with the first driver 604. It plays a key role in transmitting power, converting the rotational power of the first driver 604 into a form suitable for transmitting to the fan gear. The first fan gear 602 is arranged on a clamping rod 903 and meshes with the driving gear 603. The first fan gear 602 receives the power transmitted by the driving gear 603 and transmits it to the second fan gear 601. At the same time, it also cooperates with the second fan gear 601 to realize the deflection movement of the clamping rod 903. In design, the parameters such as the fan angle and the number of teeth of the first fan gear 602 should be determined according to the deflection angle requirements of the clamping rod 903 and the power transmission requirements of the entire transmission system. Only in this way can it be ensured that it is well meshed with the driving gear 603 and the second fan gear 601, thereby ensuring the smoothness of power transmission and the accuracy of the deflection action of the clamping rod 903. The second fan gear 601 is arranged on another clamping rod 903 and meshes with the first fan gear 602. It works together with the first sector gear 602 to realize the deflection movement of the clamping rod 903. When the first sector gear 602 and the second sector gear 601 are meshed and rotated with each other, the clamping rod 903 will be deflected and opened or closed along the strip groove 503. The second sector gear 601 needs to match the first sector gear 602, including parameters such as the sector angle and the number of teeth. It should be tightly and smoothly meshed with the first sector gear 602 to ensure that the clamping rod 903 can accurately perform the deflection movement as required and maintain good transmission performance during long-term use. The power is provided by the first driver 604, and the deflection opening or closing action of the clamping rod 903 along the strip groove 503 is accurately realized through the sequential transmission and interaction of the driving gear 603, the first sector gear 602 and the second sector gear 601, providing a precise control mechanism for the clamping member 9 to clamp and release the cable 8 and the wire rope 7.

[0034] Furthermore, the conveying member includes: a plurality of pressure rollers 14 , wherein the plurality of pressure rollers 14 are rotatably disposed on the discharge side of the winding drum 11 , and the relatively arranged pressure rollers 14 are used to compress the binding wire 13 and then pull the binding wire 13 out of the winding drum 11 .

[0035] In the above scheme, when the tying wire 13 needs to be pulled out, the pressure roller 14 starts to rotate. The pressure rollers 14 arranged opposite to each other exert pressure on the tying wire 13 through their own rotation, and this pressure increases the friction between the tying wire 13 and the winding drum 11, thereby stably pulling the tying wire 13 out of the winding drum 11. At the same time, due to the rotation of the pressure roller 14, the tying wire 13 is subjected to a forward pulling force during the pulling process, and this pulling force and the pressure act together, so that the tying wire 13 can be pulled out at a suitable speed and tension, avoiding the tying wire 13 from being loosened, entangled or broken.

[0036] Furthermore, the tightening member 12 includes: a second driver 1202, which is arranged in the box body 501; a first driving gear 1201, which is arranged on the second driver 1202; a second driving gear 1203, which is rotatably arranged on the box body 501, and the second driving gear 1203 is meshed with the first driving gear 1201; a T-shaped rod 1204, which is arranged on the second driving gear 1203, and one end of the T-shaped rod 1204 away from the second driving gear 1203 extends out of the box body 501, and the T-shaped rod 1204 has a plurality of threading holes 1205, and the threading holes 1205 are connected to the threading groove 901, and the tying wire 13 passes through the T-shaped rod 1204, and the T-shaped rod 1204 is used to tighten and knot the tying wire 13.

[0037] In the above scheme, the second driver 1202 is a motor, and the second driver 1202 is used to drive the first driving gear 1201 and the second driving gear 1203 to rotate. When the second driving gear 1203 rotates, it can drive the T-shaped rod 1204 to rotate, and the binding wire 13 running through the T-shaped rod 1204 will be driven by the T-shaped rod 1204 to realize rotation and knotting, and complete the bundling. The T-shaped rod has a plurality of threading holes 1205, and these threading holes 1205 are evenly distributed on the crossbar part (or distributed at a specific position according to actual needs). The size of the threading hole 1205 should match the diameter of the binding wire 13, which can ensure that the binding wire 13 can pass smoothly and will not make the binding wire 13 too loose in the hole. Because the binding wire 13 runs through the threading hole 1205 of the T-shaped rod and the threading hole 1205 is connected to the threading groove 901, when the T-shaped rod rotates, the binding wire 13 will be tightened as the T-shaped rod rotates. During the rotation, the tying wire 13 will gradually wrap around itself to form a tight knot. This tightening method can ensure that the tying wire 13 is firmly fixed on the cable 8 and the wire rope 7 to prevent loosening during use. For example, if the tying wire 13 is initially loosely wound around the cable 8 and the wire rope 7, as the T-bar rotates, the tying wire 13 will tighten around and around, and finally form a tight knot, which tightly fixes the cable 8 and the wire rope 7 together.

[0038] Furthermore, it also includes: a shearing piece 10, which is arranged in the box body 501, and the shearing piece 10 is located on the side of the pressure roller 14 away from the winding drum 11, and the shearing piece 10 is used to cut the binding wire 13.

[0039] In the above scheme, after the bundling operation is completed, the excess bundling wire 13 needs to be processed. At this time, the shearing member 10 is operated to close the two blades relatively. Since the blades are sharp and have a suitable shearing force, when they are closed, the bundling wire 13 can be easily cut. This process is like cutting the bundling wire 13 with ordinary scissors. And the operation is performed inside the box body 501 to meet the processing requirements of the bundling wire 13 during the laying process of the underground cable 8.

[0040] Furthermore, it also includes: a clamping member 15, which is arranged on the outer wall of the box body 501, and the clamping member 15 is located between the T-shaped rod 1204 and the box body 501, and the clamping member 15 has a clamping end 1501, and the clamping end 1501 is used to clamp one end of the binding wire 13 surrounding the wire rope 7 and the cable 8.

[0041] In the above scheme, during the tightening process, the clamping member 15 can clamp a section of the tying rope away from the winding drum 11, which is convenient for the clamping member 15 to tie a knot. The clamping member 15 includes a steering gear, which is installed on the front end surface of the box body 501, and two clamping blocks arranged in a scissor-like manner or horizontally, and the clamping blocks have connecting serrations.

[0042] Furthermore, the lay direction of the steel wire rope 7 is opposite to the lay direction of the steel wires in the cable 8 .

[0043] In the above scheme, the steel wire rope 7 is used to be lowered synchronously with the cable 8, and its lay direction is opposite to the lay direction of the steel wires in the cable 8. This setting can effectively prevent the cable 8 from twisting during the lowering process due to its own lay direction being the same as the lay direction of the steel wire rope 7, thereby ensuring the quality and safety of the laying of the cable 8. For example, in some deep wells 1, this lay direction setting can avoid damage to the cable 8 due to twisting, thereby increasing the service life of the cable 8.

[0044] The method for laying multiple cables 8 in a narrow space of a deep well comprises the following steps: S1. According to the steel beam frame structure of the construction hoisting tray 2 equipped with the shaft 1 and the actual diameter of the cable tray 3, the model and specifications of the hoisting tray 2 on each floor are reasonably distributed; S2, determine the installation position of the fixed card 4; S3, bundling the steel wire ropes 7 and cables 8 between adjacent cable 8 fixing clamps 4.

[0045] In the above scheme, the detailed steps are as follows: Step S1, according to the steel beam frame structure of the hoisting tray 2 equipped with the shaft 1, combined with the actual diameter of the cable drum 3, the model and specifications of each layer of the hoisting tray 2 are reasonably distributed. For example, in the shaft 1 of the western air intake shaft of Gaojiabao Coal Mine, considering the bearing capacity and spatial layout of the steel beam of the hoisting tray 2, as well as the size and weight of the cable drums 3 of different models and specifications, the placement position of the cable drum 3 on each layer of the hoisting tray 2 is reasonably arranged. In this way, the stability and safety of the hoisting tray 2 can be ensured, and the lowering operation of the cable 8 is also facilitated.

[0046] Step S2: Determine the installation position of the fixing card 4. For example, according to the layout of other facilities in the wellbore 1 and the laying path of the cable 8, determine the reasonable installation position of the fixing card 4. The position of the fixing card 4 should take into account factors such as the direction of the cable 8, the tension distribution, and the safe distance from other facilities. By reasonably determining the position of the fixing card 4, the movement of the cable 8 and the wire rope 7 can be effectively restricted, and the quality and safety of the laying can be improved.

[0047] Step S3: Bundle the steel wire rope 7 and cable 8 between the adjacent cable 8 fixing cards 4. During the lowering process of the cable 8, the bundler 5 is used to bundle the steel wire rope 7 and cable 8 between the adjacent fixing cards 4. First, the bundler 5 is lowered to a suitable position, and then the clamping member 9 is opened, and the cable 8 and the steel wire rope 7 are placed in the accommodating area 902, and the clamping rod 903 is closed and clamped. Next, the conveying member pulls out the bundling wire 13, and winds it around the outer circumference of the cable 8 and the steel wire rope 7. The tightening member 12 tightens and knots the bundling wire 13, and finally the shearing member 10 cuts off the excess bundling wire 13, and the clamping member 15 clamps one end of the bundling wire 13. Through this bundling operation, the relative positions of the cable 8 and the steel wire rope 7 can be further fixed to prevent them from being displaced or twisted during the laying process.
