Description

Technical Field

[0001] This invention belongs to the technical field of cable laying equipment, and specifically relates to a cable laying equipment for tunnel sections. Background Technology

[0002] Cable laying is a core supporting process in tunnel construction and operation, and its construction quality and efficiency directly affect the stable operation of tunnel power supply, communication and other systems. Currently, cable laying in tunnel sections mostly adopts a manual-assisted simple machinery operation mode, which has many technical defects and cannot meet the needs of large-scale and efficient construction.

[0003] In existing technologies, manual cable laying relies on workers dragging cables to pre-designated cable trenches. This method is not only labor-intensive and inefficient, but also prone to tangling and misalignment when laying multiple cables simultaneously, resulting in high subsequent cleanup costs. While simple mechanical laying equipment can replace some manual dragging work, it generally has limited functionality and lacks integrated cable management, cleaning, angle adjustment, and precise pushing structures. Specifically, traditional equipment cannot flexibly adjust the cable laying angle according to the different heights and locations of cable trenches within the tunnel, leading to low cable-to-trench connection accuracy and susceptibility to impact damage. To address these issues, this invention provides a cable laying equipment for tunnel sections. Summary of the Invention

[0004] To address the aforementioned technical problems, the technical solution adopted by this invention is: a cable laying equipment for tunnel sections, comprising: Railcar; A support mechanism is installed on the railcar and is used to support the cable. A pushing mechanism, which is mounted on a support mechanism, is used to push the cable into the cable trough; An angle adjustment mechanism is installed on the railcar and is used to adjust the pitch angle of the support mechanism, thereby adjusting the height of the cable relative to the cable trough. The cable management mechanism, which is mounted on a railcar, is used to neatly transport cables into the cable trough. A spraying mechanism, which is installed on a railcar, is used to allow cables to pass smoothly through the cable management mechanism and to clean dirt from the surface of the cables.

[0005] Furthermore, the support mechanism includes a rotating arm and a support arm. One end of the rotating arm is rotatably connected to the support, and the other end of the rotating arm is fixedly connected to one end of the support arm. A guide roller and a pushing mechanism are provided on the end of the support arm away from the rotating arm. The support is fixedly installed on the railcar, and the rotating arm is connected to the angle adjustment mechanism.

[0006] Furthermore, the pushing mechanism includes a cylinder fixedly mounted on the support arm, the extended end of the cylinder being fixedly connected to a wedge block, the wedge block being slidably mounted on the support arm, the wedge block having an inclined surface, the inclined surface being slidably engaged with a plurality of ball joint rods slidably mounted on the support arm, and a return spring being provided between the ball joint rods and the support arm.

[0007] Furthermore, the angle adjustment mechanism includes a hydraulic cylinder and a hydraulic pump. One end of the hydraulic cylinder is hinged to the railcar, and the other end of the hydraulic cylinder is hinged to the rotating arm. The hydraulic pump is fixedly installed on the railcar, and the hydraulic cylinder and the hydraulic pump are connected.

[0008] Furthermore, the cable management mechanism includes two sets of cable management rollers, each set of which includes multiple cable management rollers arranged linearly and evenly. The cable management rollers are rotatably mounted on a bracket, which is fixedly mounted on a railcar. When laying cables, multiple strands of cable pass through the space between two adjacent cable management rollers.

[0009] Furthermore, the cable management mechanism also includes a rectangular frame, which is fixedly mounted on a bracket. The rectangular frame has horizontal and vertical rods with mutually perpendicular central axes arranged on it. Sliding blocks are rotatably mounted at both ends of the horizontal and vertical rods, and these sliding blocks are slidably mounted on the rectangular frame. A return spring is provided between the sliding blocks and the rectangular frame. There are two horizontal rods arranged symmetrically, and two sets of vertical rods arranged symmetrically. Each set of vertical rods includes two vertical rods, and the two sets of vertical rods and the two horizontal rods enclose an area that allows cables to pass through.

[0010] Furthermore, the cable management mechanism also includes a positioning clamp and a limiting frame. There are multiple limiting frames, which are arranged linearly on the rotating arm. The positioning clamp is detachably connected to the positioning hole one on the rectangular frame and the positioning hole two on the sliding block.

[0011] Furthermore, the spraying mechanism includes a liquid storage tank, which is fixedly installed above the bracket and rotatably connected to the thread-sorting roller. The liquid storage tank has a two-layer structure, with piston rod one and piston rod two slidably installed on each layer. Piston rod one is fixedly connected to sliding rod one, and piston rod two is fixedly connected to sliding rod two. Both sliding rod one and sliding rod two are fixedly connected to a movable frame. The movable frame is slidably installed above the liquid storage tank, and a rectangular groove on the movable frame slides in cooperation with a boss. The boss is fixedly installed on a disc, and the disc is rotatably installed above the liquid storage tank.

[0012] Furthermore, the spraying mechanism also includes an upper roller brush and a lower roller brush arranged opposite to each other. The upper roller brush and the lower roller brush are fixedly connected to the output shafts of motor one and motor two, respectively. Motor one and motor two are fixedly mounted on the bracket. One end of a belt assembly is connected to the output shaft of motor one, and the other end of the belt assembly is connected to a thread-collecting roller. A lever is fixedly connected to the upper roller brush. The lever is slidably engaged with a receiving box. The receiving box is fixedly connected to the bracket. A leakage hole is provided on the receiving box. The leakage hole is connected to a collecting bucket through a collecting pipe. The collecting bucket is fixedly mounted on the bracket, and a cooling pipe is connected to the collecting bucket. The cooling pipe is wound around a hydraulic pump.

[0013] Furthermore, the liquid storage tank is equipped with multiple nozzles (first and second), with nozzles (first) located between two sets of thread-reaming rollers and nozzles (second) facing the receiving box and located above the receiving box.

[0014] The beneficial effects of this invention compared with the prior art are: (1) This invention uses a support mechanism, a pushing mechanism, an angle adjustment mechanism, a cable management mechanism and a spraying mechanism to work together, replacing the traditional manual dragging and decentralized process. The cable goes through spray cleaning, cable management, angle adjustment and precise pushing in sequence, without the need for additional process breakdown, which greatly shortens the construction cycle, significantly reduces the labor intensity of construction personnel, and is suitable for the needs of large-scale tunnel cable laying; (2) The spraying mechanism integrates cleaning and lubrication functions. The first nozzle sprays cleaning liquid to remove dirt from the cable surface, and the second nozzle sprays lubricant to improve the smoothness of laying. The cleaning fluid and lubricant are recycled to the collection bucket through the receiving box and collection pipe to realize resource recycling. At the same time, the recycled liquid is cooled by the cooling pipe to dissipate heat from the hydraulic pump, which solves the problem of high temperature heat generation of the power components, extends the service life of the equipment, and improves the stability of operation. (3) The angle adjustment mechanism can flexibly adjust the pitch angle of the support mechanism through the hydraulic cylinder and hydraulic pump to adapt to cable troughs of different heights and positions, ensuring that the cable and cable trough are accurately connected, which can meet different construction needs and is highly practical.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

The terms "first," "second," etc., are used for descriptive purposes only and do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The term "comprising" and its variations as used in this invention are open-ended, meaning "including but not limited to". The term "based on" means "at least partially based on".

[0029] Example: Figure 1 — Figure 10 The cable laying equipment shown includes: Railcar 1; A support mechanism is installed on track vehicle 1 and is used to support the cable. A pushing mechanism, which is mounted on the support mechanism, is used to push the cable into the cable trough. An angle adjustment mechanism is installed on the track vehicle 1. The angle adjustment mechanism is used to adjust the pitch angle of the support mechanism, thereby adjusting the height of the cable relative to the cable trough. The cable management mechanism is installed on the railcar 1 and is used to neatly transport the cables into the cable tray. The spraying mechanism is installed on the railcar 1. The spraying mechanism is used to allow the cable to pass smoothly through the cable management mechanism and to clean the dirt on the surface of the cable.

[0030] like Figure 1 , Figure 2 , Figure 10 As shown, when laying cables, the laying equipment is first moved to the area where the cables need to be laid, such as inside a tunnel; at the same time, one or more rolls of cables to be laid are placed on the railcar 1 and located on the side close to the bracket 9, so that the cables can be cleaned by the spraying mechanism and organized by the cable management mechanism in sequence during the laying process, and then laid into the cable trough.

[0031] In this embodiment, the cable trough is a structure for accommodating cables and will be installed in advance according to construction needs. In order to adapt to cable troughs of different heights, this embodiment provides an angle adjustment mechanism. By adjusting the pitch angle of the support mechanism, the height of the cable can be adjusted.

[0032] like Figure 10 As shown, during the cable laying process, one end of the cable is first passed through the rectangular frame 28 and the limiting frame 3 in the cable management mechanism, and then fixed to the right side of the cable trough. Then, the railcar 1 is moved to the left, and the cable trough is located above. The cable can be pushed into the cable trough by the pushing mechanism. Figure 10 The directions mentioned are named after the top view of the equipment being laid, as would be apparent to those skilled in the art. In actual construction, the cable trough is located above the railcar 1, and the projection of the cable trough on the ground is parallel to the projections of the rotating arm 2 and the support arm 4 on the ground.

[0033] In addition, the laying equipment also includes a control system, which includes a PLC, memory, encoder, etc. The control system is arranged in the electrical control cabinet 39, which is fixedly installed on the railcar 1. Through the control system, the construction personnel can control the operation of the spraying mechanism, the pushing mechanism and the angle adjustment mechanism. The control can be operated by buttons set on the electrical control cabinet 39. Since the control system is existing technology and is not the focus of this invention, it will not be described in detail here.

[0034] The support mechanism includes a rotating arm 2 and a support arm 4. One end of the rotating arm 2 is rotatably connected to the support 6, and the other end of the rotating arm 2 is fixedly connected to one end of the support arm 4. A guide roller 5 and a pushing mechanism are provided on the end of the support arm 4 away from the rotating arm 2. The support 6 is fixedly installed on the railcar 1, and the rotating arm 2 is connected to the angle adjustment mechanism.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 10 As shown, the rotating arm 2 and the support arm 4 can be fixed together by welding or bolts. In order to reduce weight while ensuring rigidity, the support arm 4 is a hollow structure and is equipped with multiple triangular mechanisms. During the cable laying process, the rotating arm 2 and the support arm 4 support the cable. A guide roller 5 is rotatably mounted on the support arm 4. During the cable laying process, the guide roller 5 plays a stabilizing role. In addition, the surface of the guide roller 5 is a smooth surface.

[0036] The pushing mechanism includes a cylinder 34 fixedly mounted on the support arm 4. The extended end of the cylinder 34 is fixedly connected to a wedge block 35. The wedge block 35 is slidably mounted on the support arm 4. An inclined surface 36 is provided on the wedge block 35. The inclined surface 36 is slidably engaged with a plurality of ball joint rods 37 slidably mounted on the support arm 4. A return spring 38 is provided between the ball joint rods 37 and the support arm 4.

[0037] like Figure 3 , Figure 4 As shown, during cable laying, if the cable is far from the cable trench or needs to be close to the cable trench, the control system can start the cylinder 34. Then, the extended end of the cylinder 34 extends, simultaneously pushing the wedge block 35 to slide on the support arm 4. At this time, the inclined surface 36 on the wedge block 35 will slide relative to the ball joint 37. As the inclined surface 36 passes the ball joint 37, it will gradually move upward (towards...). Figure 10 (Based on the perspective) Push the cable to push it into the cable groove. The function of the return spring 38 is to assist the return of the ball head rod 37.

[0038] The angle adjustment mechanism includes a hydraulic cylinder 7 and a hydraulic pump 8. One end of the hydraulic cylinder 7 is hinged to the railcar 1, and the other end of the hydraulic cylinder 7 is hinged to the rotating arm 2. The hydraulic pump 8 is fixedly installed on the railcar 1, and the hydraulic cylinder 7 is connected to the hydraulic pump 8.

[0039] like Figure 1 , Figure 2 As shown, when adapting to different height operation requirements, the hydraulic pump 8 can be started by the control system to deliver hydraulic oil to the hydraulic cylinder 7, causing the extended end of the hydraulic cylinder 7 to extend. This will push the rotating arm 2 to rotate relative to the support 6, thereby increasing the height of the support arm 4 to meet the requirements of the application scenario.

[0040] The cable management mechanism includes two sets of cable management rollers 20. Each set of cable management rollers 20 includes multiple cable management rollers 20 arranged linearly and uniformly. The cable management rollers 20 are rotatably mounted on the bracket 9. The bracket 9 is fixedly mounted on the railcar 1. When laying cables, multiple strands of cables pass through the space between two adjacent cable management rollers 20.

[0041] The cable management mechanism also includes a rectangular frame 28, which is fixedly mounted on the bracket 9. The rectangular frame 28 has horizontal bars 29 and vertical bars 30 with their central axes perpendicular to each other. Sliding blocks 31 are rotatably mounted at both ends of the horizontal bars 29 and the vertical bars 30, and the sliding blocks 31 are slidably mounted on the rectangular frame 28. A return spring 33 is provided between the sliding blocks 31 and the rectangular frame 28. There are two horizontal bars 29, which are symmetrically arranged. There are two sets of vertical bars 30, which are symmetrically arranged. Each set of vertical bars 30 includes two vertical bars 30. The two sets of vertical bars 30 and the two horizontal bars 29 enclose an area that allows cables to pass through.

[0042] The cable management mechanism also includes a positioning clamp 32 and a limiting frame 3. There are multiple limiting frames 3, which are arranged linearly on the rotating arm 2. The positioning clamp 32 is detachably connected to the positioning hole 1 on the rectangular frame 28 and the positioning hole 2 on the sliding block 31.

[0043] like Figure 5 , Figure 8 , Figure 9 As shown, during cable laying, the cable reel is arranged on the railcar 1. Whether it's a single cable or multiple strands, during laying, the cable is first passed between two adjacent cable management rollers 20. If it's multiple strands, they are passed between two adjacent cable management rollers 20 respectively (referring to adjacent cable management rollers 20 located in the same group; in this embodiment, two groups of cable management rollers 20 are provided to improve the stability of cable transport). Since the two ends of the cable management rollers 20 are rotatably mounted between the bracket 9 and the liquid storage tank 17, and the surface of the cable management rollers 20 is smooth, the cable can pass through smoothly. The cable passing through the cable management rollers 20 will move... In the area enclosed by the horizontal bar 29 and the vertical bar 30, multiple cables can be gathered together (this operation is also performed if it is a single cable). Specifically, remove multiple positioning clips 32, and then adjust the distance between the two horizontal bars 29 and the distance between the two sets of sliding blocks 31 according to the number of cables. After adjusting to the appropriate position, insert the positioning clips 32 into positioning holes one and two. At this point, the positions of the horizontal bar 29 and the vertical bar 30 are determined, and the center encloses an area that allows the cable to pass through. The purpose of setting the return spring 33 is to assist in the reset of the horizontal bar 29 and the vertical bar 30. By gathering the cables together through the horizontal bar 29 and the vertical bar 30, and then letting the cables pass through the limiting frame 3 together to complete the laying, the laid cables will not be messy. Furthermore, the horizontal rod 29 and the vertical rod 30 are rotatably mounted to the sliding block 31, so when the cable passes through the horizontal rod 29 and the vertical rod 30, even if the horizontal rod 29 and the vertical rod 30 rotate due to friction, the horizontal rod 29 and the vertical rod 30 can easily rotate relative to the sliding block 31 without increasing the resistance to the cable passing through.

[0044] The spraying mechanism includes a liquid storage tank 17, which is fixedly installed above the bracket 9 and rotatably connected to the thread-collecting roller 20. The liquid storage tank 17 has a two-layer structure, with piston rod one and piston rod two slidably installed on each layer. Piston rod one is fixedly connected to sliding rod one 15, and piston rod two is fixedly connected to sliding rod two 16. Both sliding rod one 15 and sliding rod two 16 are fixedly connected to the movable frame 14. The movable frame 14 is slidably installed above the liquid storage tank 17, and the rectangular groove on the movable frame 14 is slidably engaged with the boss 13. The boss 13 is fixedly installed on the disc 12, and the disc 12 is rotatably installed above the liquid storage tank 17.

[0045] The spraying mechanism also includes an upper roller brush 22 and a lower roller brush 23 arranged opposite to each other. The upper roller brush 22 and the lower roller brush 23 are fixedly connected to the output shafts of motor 21 and motor 10, respectively. Motor 10 and motor 21 are fixedly mounted on the bracket 9. One end of the belt assembly 11 is connected to the output shaft of motor 10. The other end of the belt assembly 11 is connected to the yarn guide roller 20. A lever 24 is fixedly connected to the upper roller brush 22. The lever 24 slides with the receiving box. The receiving box is fixedly connected to the bracket 9. A leakage hole 25 is provided on the receiving box. The leakage hole 25 is connected to the collecting bucket 27 through the collecting pipe 26. The collecting bucket 27 is fixedly mounted on the bracket 9, and a cooling pipe is connected to the collecting bucket 27. The cooling pipe is wound around the hydraulic pump 8.

[0046] The liquid storage tank 17 is equipped with multiple nozzles 18 and multiple nozzles 29. The nozzles 18 are located between the two sets of thread rollers 20, and the nozzles 29 face the receiving box and are located above the receiving box.

[0047] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, before the cable passes through the two sets of cable management rollers 20 and reaches the rectangular frame 28, the surface of the cable is treated by a spraying mechanism; specifically, the control system starts motor 10 and motor 21; the output shaft of motor 10 drives the belt assembly 11 and the lower roller brush 23 to rotate, and the output shaft of motor 21 drives the upper roller brush 22 and the lever 24 to rotate.

[0048] When the output shaft of motor 10 drives the belt assembly 11 to rotate, the belt assembly 11 drives the disc 12 to rotate. At this time, the boss 13 on the disc 12 drives the movable frame 14 to slide back and forth on the liquid storage tank 17, thereby driving the sliding rod 15 and the sliding rod 16 to slide back and forth through the movable frame 14. The liquid storage tank 17 has a double-layer structure, one layer stores cleaning fluid and the other stores lubricant. During the reciprocating motion of the sliding rod 15, the piston rod connected to the sliding rod 15 will move in the liquid storage tank. The internal sliding mechanism 17 intermittently sprays cleaning fluid from nozzle 18, which cleans the cable surface after passing through the cable management roller 20. The reciprocating sliding rod 16 drives piston rod 2 to slide, intermittently spraying lubricant from nozzle 19, which falls onto the cleaned cable. In addition, the brushes on the rotating upper roller brush 22 and lower roller brush 23 brush away residual impurities on the cable surface and spread the lubricant evenly, facilitating cable laying.

[0049] In this embodiment, the cleaning fluid sprayed from nozzle 18 and the lubricant sprayed from nozzle 219 will eventually flow into the receiving box and be pushed to the leakage hole 25 by the rotating lever 24, and then enter the collection bucket 27 through the collection pipe 26 to complete the collection.

[0050] Preferably, since the cleaning fluid and lubricating fluid are both at low temperatures, a cooling pipe can be installed on the collection tank 27 after collection is complete. The flow path of the cooling pipe passes through the hydraulic pump 8, so that during the process of starting the hydraulic pump 8 and generating heat, the waste cleaning fluid and lubricant can physically cool the hydraulic pump 8. Of course, one end of the cooling pipe is connected to the collection tank 27, and the other end is connected to an additional collection box.

[0051] It is worth noting that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
