Description

Technical Field

[0001] The present invention relates to the technical field of mine equipment trains, and more specifically, it relates to an auxiliary device for cable and pipe brackets of mine equipment trains. Background Art

[0002] As a key transportation system for fully mechanized coal mining faces underground in coal mines, the mine equipment train undertakes the tasks of relocating heavy equipment such as hydraulic supports, pumping stations, and switch cabinets, as well as dynamically laying cables and hydraulic pipelines.

[0003] Since the mine equipment train needs to synchronously relocate power supply, liquid supply, communication and other pipeline networks in a long and narrow, dynamically changing roadway, and the number of cables and pipes it carries is large, corresponding cable and pipe brackets are required to support and fix the cables and pipes. The cable and pipe brackets usually consist of a bracket body and cable fixing buckles. The cable and pipeline are carried by the bracket body and fastened with fixing buckles.

[0004] Due to factors such as the dynamic movement of the train and the pushing and pulling movement between adjacent carriages, a certain elongation margin should be reserved at the position of the push-pull cylinder for adjacent existing cable and pipe brackets to ensure that the cables and liquid pipes bear as little tension as possible when the push-pull cylinder extends. However, the reserved margin is relatively long when the push-pull cylinder is in the retracted state, resulting in the cables and pipes drooping in a "U" shape at this time. In this way, this part shakes and vibrates more strongly than the fixed position during the train operation, and a series of problems such as entanglement, hitting the wall, and damage are likely to occur. Summary of the Invention

[0005] The present invention discloses an auxiliary device for cable and pipe brackets of mine equipment trains to solve the technical problems in the above background art.

[0006] The present invention discloses an auxiliary device for cable and pipe brackets of mine equipment trains, which includes tray A and tray B. Brackets are arranged on the tops of tray A and tray B. Brackets for supporting cables and pipes are arranged on both sides of the top ends of the brackets. A number of push-pull cylinders are movably connected between tray A and tray B, and further includes:

[0007] A tightening component, which is arranged between tray A and tray B and is used to tighten the cables and pipes that are stretched and drooping. The tightening component includes a number of main supporting wheels and auxiliary supporting wheels. The main supporting wheel is arranged between the two auxiliary supporting wheels, and the three are connected in a triangle. The cables and pipes are tightened after passing around the auxiliary supporting wheels and the main supporting wheel respectively;

[0008] A maintaining component, which is used to maintain the relative height difference between the main supporting wheel and the auxiliary supporting wheel. When the height of the main supporting wheel is higher than that of the auxiliary supporting wheel, the cables and pipes are tightened;

[0009] It further includes a movable component for relaxing the cables and pipes when the push-pull cylinder extends to avoid pulling.

[0010] Preferably, a plurality of fixing buckles are installed on the surface of the bracket, and the fixing buckles connect the cable pipe to the bracket by means of bolt fixing, snap fixing, binding fixing and the like.

[0011] Preferably, the maintaining assembly includes a supporting frame arranged on the side of pallet B close to pallet A, and two movable blocks are provided on the top of the supporting frame. The movable blocks are connected to the main supporting wheel through the main movable shaft, and fixed plates are also fixedly connected on both sides of the supporting frame. A connecting rod is hinged on the surface of the fixed plate, and the connecting rod is connected to the secondary supporting wheel through the secondary movable shaft.

[0012] Preferably, the fixing plate is U-shaped, and connecting rods are hinged at both ends. Guide grooves are provided at the opposite ends of the two connecting rods, and the main movable shaft is inserted into the guide grooves.

[0013] Preferably, the movable block is connected to the supporting frame via a spring B.

[0014] Preferably, the movable component includes a connecting plate fixedly connected to the output end of the push-pull cylinder, the connecting plate is connected to the movable block through a pull rope, a square hole adapted for the pull rope is opened on the surface of the supporting frame, one end of the pull rope passes through the square hole and extends inside the supporting frame and is fixedly connected to the movable block.

[0015] Preferably, the inner wall of the square hole is rotatably connected to a fixed pulley adapted to the pull rope.

[0016] Preferably, the main supporting wheel is sleeved on the surface of the main movable shaft, and the main movable shaft is connected to the main supporting wheel through a spring A.

[0017] Preferably, the bottom of the pallet A and the pallet B are both equipped with track wheels for running on a track surface.

[0018] Preferably, the maximum extension stroke of the push-pull cylinder is set between 1.2 meters and 1.5 meters.

[0019] Preferably, the cable pipe between the pallet A and the pallet B has a reserved extension margin of ≥2.5 meters.

[0020] The beneficial effects of the present invention are:

[0021] The present invention arranges several groups of main supporting wheels and auxiliary supporting wheels with a certain height difference, so that the cable pipes are wound tightly in a wave-like manner when they are passed around. The wave-shaped distribution forms a segmented constraint through multiple main supporting wheels and auxiliary supporting wheels, thereby suppressing the swing of the cable pipes when the train is bumpy, and reducing the risks of accidental collision, wall impact and entanglement of the cable pipes. Furthermore, the external force generated by the shaking of the cable pipes is absorbed and dispersed by multiple pulley nodes, avoiding local stress concentration and effectively extending the service life of the cable pipes.

[0022] By setting up movable components, when the train needs to move forward or turn, etc., the output of the hydraulic cylinder causes the main supporting wheels and the auxiliary supporting wheels to adjust their heights accordingly, relax the cable pipe, so as to synchronously respond to elongation and release the original elongation reserve, effectively avoiding pulling on the cable pipe and improving the applicability of the device.

Detailed Embodiments

[0031] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0032] In the embodiments of the present invention, a cable pipe bracket auxiliary device for a mine equipment train is disclosed, as shown in Figure 1 and Figure 2As shown in the figure, it includes tray A1 and tray B11. Tray A1 and tray B11 are part of the entire equipment train system and are adjacent to each other. The parts of tray A1 and tray B11 that are away from each other are respectively connected to other train equipment by means of hard connection with tie rods. There are brackets 12 on the tops of tray A1 and tray B11. The brackets 12 are fixed on the top surfaces of tray A1 and tray B11 by means of welding, bolts, etc. On both sides of the top of the bracket 12, there are brackets 13 for supporting cable pipes. The brackets 13 are installed on the surface of the bracket 12 by means of welding fixation or bolt fixation, etc. There is at least one groove for accommodating cable pipes on the surface of the bracket 13. In this document, there are two grooves for respectively supporting different types of cables, various pipelines, etc. There are several push-pull cylinders 2 movably connected between tray A1 and tray B11. The push-pull cylinders 2 are hydraulic cylinders and should be set to at least two. While providing stable thrust, it is also convenient for steering.

[0033] As Figure 3 and Figure 4 shown in the figure, it also includes a tightening component, which is arranged between tray A1 and tray B11 and is used to tighten the cable pipes that are vertically placed and elongated. The tightening component includes several main supporting wheels 411 and auxiliary supporting wheels 423. The main supporting wheels 411 are arranged between the two auxiliary supporting wheels 423, and the connection line of the three forms a triangle. The cable pipes are tightened after passing around the auxiliary supporting wheels 423 and the main supporting wheels 411 respectively. There is a maintaining component, which is used to maintain the relative height difference between the main supporting wheels 411 and the auxiliary supporting wheels 423. When the height of the main supporting wheels 411 is higher than that of the auxiliary supporting wheels 423, the cable pipes are tightened.

[0034] It also includes an active component for relaxing the cable pipes when the push-pull cylinders 2 extend to avoid pulling.

[0035] Specifically, under normal conditions, the height of the main supporting wheels 411 is greater than that of the two auxiliary supporting wheels 423, and the two auxiliary supporting wheels 423 are at the same height. The cable pipes led out from the bracket 13 first bypass under the first auxiliary supporting wheel 423, then bypass above the main supporting wheel 411, and then bypass under the second auxiliary supporting wheel 423, and finally are fixed on another opposite bracket 13. At this time, the cable pipes are in a wavy or "W" shape on the side and are tightened by the main supporting wheels 411 and the auxiliary supporting wheels 423. At this time, the main supporting wheels 411 are upward and the auxiliary supporting wheels 423 are downward, which will further tighten the cable pipes, making the elongation allowance reserved by them be effectively utilized after multiple bends, and reducing problems such as shaking and hitting the wall caused by natural vertical placement.

[0036] Among them, as Figure 1 shown in the figure, several fixing buckles 14 are installed on the surface of the bracket 13. The fixing buckles 14 connect the cable pipes in the bracket 13 by means of bolt fixation, snap fixation, and binding fixation, etc. First, the cable pipes are placed in the grooves on the surface of the bracket 13 in a certain order, and then the cable pipes are further fixed by the fixing buckles 14 to complete the support of the cable pipes.

[0037] As Figure 5 shown, in this embodiment, the maintaining assembly includes a carrier 3 disposed on the side of the tray B11 close to the tray A1. Two movable blocks 4 are provided on the top of the carrier 3. The movable blocks 4 are slidably connected in the carrier 3. The movable blocks 4 are connected to the main supporting wheels 411 through main movable shafts 41. In this way, when the movable blocks 4 slide up and down in the carrier 3, the main movable shafts 41 will synchronously drive the main supporting wheels 411 to move up and down, adjusting the tightening degree of the main supporting wheels 411 on the cable pipe. Fixed plates 42 are fixedly connected to both sides of the carrier 3. Link rods 421 are hinged on the surfaces of the fixed plates 42. The link rods 421 are connected to the auxiliary supporting wheels 423 through auxiliary movable shafts 422. One end of the auxiliary movable shaft 422 is fixedly connected to the surface of the link rod 421, and the other end is rotatably connected to the auxiliary supporting wheel 423.

[0038] Further, the fixed plate 42 is in a "U" shape, and link rods 421 are hinged at both ends thereof. Guide grooves are formed at the opposite ends of the two link rods 421, and the main movable shaft 41 is disposed through the guide grooves. The two link rods 421 cross each other, and the intersection point thereof is penetrated by the main movable shaft 41. In this way, when the main movable shaft 41 moves up and down, it will drive the two link rods 421 to rotate. Since the link rods 421 are hinged on the surface of the fixed plate 42, the link rods 421 will rotate around the hinge point, thereby driving the auxiliary movable shaft 422 to move in the opposite direction of the main movable shaft 41, so that the moving direction of the auxiliary supporting wheel 423 is opposite to the moving direction of the main supporting wheel 411.

[0039] Specifically, the hinge point between the link rod 421 and the fixed plate 42 is located between the main movable shaft 41 and the auxiliary movable shaft 422. Therefore, when the main movable shaft 41 moves up to drive the link rod 421 to rotate, the auxiliary movable shaft 422 will synchronously move down. Since the cable pipe bypasses below the auxiliary supporting wheel 423 and above the main supporting wheel 411 respectively, the cable pipe will be further tightened in this state. On the contrary, when the main movable shaft 41 moves down to drive the link rod 421 to rotate in the reverse direction, the auxiliary movable shaft 422 will synchronously move up, relaxing the cable pipe at this time and restoring its reserved elongation margin.

[0040] Wherein, the movable block 4 is connected to the carrier 3 through a spring B43. Both ends of the spring B43 are fixedly connected to the movable block 4 and the carrier 3 respectively. Through the setting of the spring B43, it keeps the movable block 4 in an upward state all the time, which is convenient for the main supporting wheel 411 and the auxiliary supporting wheel 423 to tighten the cable pipe. Further, during the operation of the entire equipment train, when there is a bump, the spring B43 plays a certain buffering role, resolving the acting force generated by the vehicle body vibration on the cable pipe and reducing the damage to the cable pipe.

[0041] The movable components include a connecting plate 21 fixedly connected to the output end of the push-pull cylinder 2. The connecting plate 21 is connected to the movable block 4 through a pull rope 211. A square hole adapted to the pull rope 211 is formed on the surface of the bearing frame 3. One end of the pull rope 211 passes through the square hole and extends inside the bearing frame 3, and is fixedly connected to the movable block 4.

[0042] Specifically, since the connecting plate 21 is arranged on the output shaft of the push-pull cylinder 2, when the push-pull cylinder 2 outputs and pushes the tray A1 forward, the output shaft of the push-pull cylinder 2 drives the connecting plate 21 to move forward synchronously, thereby pulling the pull rope 211. The pull rope 211 pulls down the movable block 4 located inside the bearing frame 3, thereby compressing the spring B43. Through the downward movement of the movable block 4, the main movable shaft 41 drives the main supporting wheel 411 to move downward, and further the auxiliary movable shaft 422 drives the auxiliary supporting wheel 423 to move upward, relaxing the cable tube wound around the surfaces of the main supporting wheel 411 and the auxiliary supporting wheel 423. Due to the output of the push-pull cylinder 2, the distance between the tray A1 and the tray B11 is enlarged. Therefore, at this time, the cable tube needs to be relaxed and have a certain elongation margin to avoid pulling. And the main movable shaft 41 drives the main supporting wheel 411 to move downward, and the auxiliary movable shaft 422 drives the auxiliary supporting wheel 423 to move upward, which can well relax the cable tube.

[0043] It should be noted that during the train operation, when steering or other states that require the tray A1 and the tray B11 to be at a certain angle are needed, by making the two push-pull cylinders 2 extend and retract different strokes to achieve this purpose. And because the elongation states of the two push-pull cylinders 2 are different at this time, and there are two groups of movable blocks 4, the cable tubes at different positions on both sides can be stretched or relaxed accordingly to adapt to the output states of different push-pull cylinders 2, achieving the purpose of more flexible operation.

[0044] Among them, a fixed pulley 31 adapted to the pull rope 211 is rotatably connected to the inner wall of the square hole. The pull rope 211 bypasses the fixed pulley 31, and its two ends are respectively fixedly connected to the movable block 4 and the connecting plate 21. In this way, when the connecting plate 21 pulls the pull rope 211, the pull rope 211 can slide on the surface of the fixed pulley 31. By the fixed pulley 31, the friction of the pull rope 211 sliding is reduced, improving the applicability.

[0045] The main supporting wheel 411 is sleeved on the surface of the main movable shaft 41, and the main movable shaft 41 is connected to the main supporting wheel 411 through a spring A412. Therefore, the main supporting wheel 411 can slide radially on the surface of the main movable shaft 41 and is buffered by the spring A412. It is applicable to the lateral shaking during the whole train operation. Through the buffering of the spring A412, the synchronous lateral shaking of the cable tube is offset and buffered, reducing the damage to the cable tube caused by external forces.

[0046] Track wheels for running on the track surface are installed at the bottom of pallet A1 and pallet B11. The track wheels are selected according to different track diameters. The track wheels can roll on the track, thereby moving pallet A1 and pallet B11.

[0047] The ultimate extension stroke of the push-pull cylinder 2 is set between 1.2 meters and 1.5 meters.

[0048] The reserved extension margin of the cable between pallet A1 and pallet B11 is ≥ 2.5 meters. Since the reserved length is greater than the longest stroke of the push-pull cylinder 2, sufficient extension margin is left to minimize the pulling of the cable and reduce the tension it bears.

[0049] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make more forms of equivalent embodiments based on the inspiration of this embodiment, all of which are protected by this embodiment.
