Description

Technical Field

[0001] The invention relates to the technical field of coal mine equipment, and in particular to a cable dragging device at the tail of a transfer machine. Background Art

[0002] The transportation system in the comprehensive mining working face includes the working face conveyor, the transfer machine and the belt conveyor. The transfer machine is located at the head of the working face conveyor and is vertically overlapped with it. The transfer machine transports the coal transported by the working face conveyor to the belt conveyor, playing a transit role. Cables and wind and water pipelines for working face equipment are generally laid on the side of the transfer machine. The cables mainly include coal mining machine cables and motor cables at the head and tail of the conveyor. These cables and wind and water pipelines turn 90° from the tail of the transfer machine to the working face, and then are laid in the cable trough and wind and water trough on the side of the conveyor.

[0003] During normal mining at the working face, the working face conveyor will move toward the working face under the push of the hydraulic support. At the same time, the movement of the working face conveyor will drive the movement of the working face cables and water pipes. At this time, the transfer machine is stationary, which will cause serious folding of the cables and water pipes at the tail of the transfer machine, easily causing damage to the cables and water pipes at the tail of the transfer machine, and it will be quite chaotic. As the working face continues to advance, the degree of chaos will be more serious, posing a serious safety hazard.

[0004] Therefore, it is necessary to provide a cable dragging device at the tail of a transfer machine to solve the above-mentioned technical problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a cable dragging device at the tail of a transfer machine, which can prevent the cables and air-water pipelines from being excessively bent and folded, and is beneficial to protecting the cables and air-water pipelines.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0007] The cable dragging device at the tail of the transfer machine includes: a fixing plate fixed on the head shell of the working face conveyor, a supporting plate is fixed on the top of the fixing plate, and the supporting plate can lift the working face cables and wind and water pipelines. It should be emphasized that before this, the working face coal mining machine cables, the conveyor head and tail motor cables, and the wind and water pipelines need to be wrapped into a bundle, so that the above cables and pipelines form a columnar structure that is approximately columnar and has a certain flexibility. Two baffles are installed on the top of the supporting plate, and the cables and wind and water pipes are located between the two baffles. The baffle is an arc-shaped structure, so that the cable can be dragged on the baffle. During the movement of the cables and Feng Shui pipelines, the cables and Feng Shui pipelines will not be cut. A pulley assembly is arranged on the side of the loader away from the working surface conveyor. The cables and Feng Shui pipes arranged along the transfer machine are installed on the pulley assembly. The cables and Feng Shui pipes are bent along the pulley assembly to avoid excessive bending and folding. A hydraulic cylinder is arranged on one side of the pulley assembly. The hydraulic cylinder can push the pulley assembly to move to ensure that the pulley assembly can move with the advancement of the working surface. The pulley assembly includes a frame, a rotating wheel is installed on the frame, and the cables and Feng Shui pipes are wound around the rotating wheel.

[0008] Preferably, a pressure roller is rotatably arranged inside the frame, and when the wrapped cables and the air-water pipes are wound around the rotating wheel, the pressure roller presses on the wrapped cables and the air-water pipes, so that the wrapped cables and the air-water pipes can stably contact with the rotating wheel.

[0009] Preferably, an elastic mechanism is provided on the frame, and the elastic mechanism includes a sleeve fixed on the frame, and part of the hydraulic cylinder extends into the inside of the sleeve. A spring is provided inside the sleeve, and both ends of the spring are respectively fixed to one side of the sleeve and one end of the hydraulic cylinder. Two sliding holes are provided on the sleeve, and two limit rods are fixed to the end head of the hydraulic cylinder, and the two limit rods respectively pass through the corresponding sliding holes.

[0010] Preferably, a plurality of connectable tracks are provided on one side of the transfer machine, a plurality of moving mechanisms are provided on the tracks, the pulley assembly and the hydraulic cylinder are respectively connected to the corresponding moving mechanisms, and the pulley assembly and the hydraulic cylinder can be moved after being connected to the tracks through the moving mechanisms.

[0011] Preferably, the moving mechanism includes a mounting plate, one side of which is rotatably mounted with two moving wheels, both of which are located on the track, and there are at least two moving mechanisms connected to the hydraulic cylinder, which are respectively fixed to the cylinder section and telescopic section of the hydraulic cylinder, and a fixing structure is also provided on the two moving mechanisms, the fixing mechanism includes a micro hydraulic cylinder fixed on the mounting plate, and a pressure plate is installed on the output shaft of the micro hydraulic cylinder.

[0012] Preferably, a bearing plate structure is fixedly installed on the side of the pulley assembly away from the hydraulic cylinder, and the bearing plate structure is fixed to the corresponding moving mechanism. The bearing plate structure is used to support the wrapped cables and Feng Shui pipes, and the bearing plate structure is more secure under the support of the moving mechanism.

[0013] Preferably, the bearing plate structure includes a bearing plate, on which a plurality of support rollers are provided. When the wrapped cables and the air-water pipes are located on the bearing plate, the support rollers will reduce the friction between the two, making the wrapped cables and the air-water pipes easier to move.

[0014] Preferably, a plurality of connectable cable supporting plates are installed on one side of the transfer machine, and the wrapped cables and air-water pipes are initially placed on the cable supporting plates. The cable supporting plates support the wrapped cables and air-water pipes, so that the wrapped cables and air-water pipes are laid neatly, which is convenient for subsequent operations.

[0015] Preferably, a bridge is provided on one side of the support plate, and the bridge is used for personnel to cross the transfer machine to enter the working surface. Four sleeves are fixed to the bottom of the bridge, and two brackets are fixed on one side of the support plate. Screws are threadedly installed on the two brackets, and the four sleeves are respectively sleeved on the top of the corresponding screws.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) After being wrapped, the cables and the ventilating and water conduits in the present invention can form a columnar structure that is approximately columnar and has a certain degree of flexibility. The original multiple cables are reduced to one, which reduces the degree of confusion. At the same time, the pulley assembly is used to support the folded parts of the wrapped cables and ventilating and water conduits to avoid excessive bending and folding of the cables and ventilating and water conduits, which is beneficial to protecting the cables and ventilating and water conduits;

[0018] (2) The pulley assembly in the present invention can move under the push of the hydraulic cylinder, so that the pulley assembly can move with the movement of the cable and the wind and water pipeline, ensuring the support for the folding of the cable and the wind and water pipeline;

[0019] (3) The arrangement of the moving mechanism in the present invention enables the hydraulic cylinder 5 to move forward intermittently, thereby enabling the pulley assembly 4 to move forward intermittently, so as to adapt to the situation where the tail cable and the wind and water pipe of the conveyor and the transfer machine move forward;

[0020] (4) The bearing plate structure of the present invention supports the cable and the air-water pipe to prevent the cable and the air-water pipe from being scratched by the cables below;

[0021] (5) In the present invention, the support plate can be connected to the bridge, so that the bridge can move with the movement of the conveyor, making the movement of the bridge more convenient. At the same time, the height of the bridge can be adjusted by the screw rod to adapt to the high and low environment of the roof of the underground tunnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0036] Example 1

[0037] like Figure 1-12 As shown, the cable dragging device at the tail of the transfer machine provided by the present invention includes: a fixing plate 1 fixed on the head shell of the working face conveyor, a support plate 2 is fixed on the top of the fixing plate 1, and the support plate 2 can lift the working face cables and wind and water pipelines. It should be emphasized that before this, the working face coal mining machine cables, the conveyor head and tail motor cables, and the wind and water pipelines need to be wrapped into a bundle so that the above cables and pipelines form a columnar structure that is approximately columnar and has a certain flexibility. Two baffles 3 are installed on the top of the support plate 2, and the cables and wind and water pipes are located between the two baffles 3. The baffle 3 is an arc structure, so that the cables and wind and water pipelines will not be cut during the process of the baffle 3 dragging the cables and wind and water pipelines to move. A pulley assembly 4 is provided on the side of the loader away from the working face conveyor, and the cables and wind and water pipes arranged along the transfer machine are installed on the pulley assembly 4 (such as Figure 4 As shown), the cable and the Feng Shui pipe are bent along the pulley assembly 4 to avoid excessive bending and folding. A hydraulic cylinder 5 is arranged on one side of the pulley assembly 4, and the hydraulic cylinder 5 can push the pulley assembly 4 to move to ensure that the pulley assembly 4 can move with the advancement of the working surface. The pulley assembly 4 includes a frame 41, and a rotating wheel 42 is installed on the frame 41. The cable and the Feng Shui pipe are wound around the rotating wheel 42. When the working surface conveyor moves forward, the baffle 3 is driven to move by the fixed plate 1 and the support plate 2. The movement of the baffle 3 drags the wrapped cable and the Feng Shui pipe to move. At the same time, the hydraulic cylinder 5 is started to extend it and push the frame 41 to move. The movement of the frame 41 drives the rotating wheel 42 to move. When the cable and the Feng Shui pipe move, the rotating wheel 42 will also rotate. During the movement of the working surface conveyor, the cable and the Feng Shui pipe will not be excessively folded at their bending parts, thereby protecting the cable and the Feng Shui pipe.

[0038] Example 2

[0039] like Figure 6 As shown, a pressure roller 43 is rotatably arranged inside the frame 41. When the wrapped cables and the air-water pipes are wound around the rotating wheel 42, the pressure roller 43 presses on the wrapped cables and the air-water pipes, so that the wrapped cables and the air-water pipes can stably contact with the rotating wheel 42.

[0040] Example 3

[0041] like Figure 6-7 As shown, the frame 41 is provided with an elastic mechanism 10, which includes a sleeve 101 fixed on the frame 41, and a portion of the hydraulic cylinder 5 extends into the sleeve 101. A spring 102 is provided inside the sleeve 101, and both ends of the spring 102 are respectively fixed to one side of the sleeve 101 and one end of the hydraulic cylinder 5. Two sliding holes 103 are provided on the sleeve 101, and two limit rods 104 are fixed on the end of the hydraulic cylinder 5. The two limit rods 104 pass through the corresponding sliding holes 103 respectively. When the working face conveyor is pushed forward, the hydraulic cylinder 5 cannot keep moving synchronously with it at all times. Sometimes there will be slight deviations in speed and distance. When deviations occur, the wrapped cables and Feng Shui pipes will move quickly through the pulley assembly 4 moving sleeve 101 (the speed is compared with the extension speed of the hydraulic cylinder 5). At this time, the spring 102 is stretched. When the limit rod 104 completes the stroke in the slide hole 103, it is necessary to stop the conveyor from moving forward in time and speed up the extension speed of the hydraulic cylinder 5. The purpose of setting the elastic mechanism 10 is to adjust the distance between the pulley assembly 4 and the hydraulic cylinder 5 in a small range to adapt to the different extensions of the conveyor and the hydraulic cylinder 5, so as to avoid the situation of strong pulling of the wrapped cables and Feng Shui pipes.

[0042] Example 4

[0043] like Figure 4-5 As shown, a plurality of connectable tracks 6 are provided on one side of the transfer machine, and a plurality of moving mechanisms 7 are provided on the track 6. The pulley assembly 4 and the hydraulic cylinder 5 are respectively connected to the corresponding moving mechanisms 7. After the pulley assembly 4 and the hydraulic cylinder 5 are connected to the track 6 through the moving mechanisms 7, they can be moved so that the two can move with the movement of the working surface conveyor, which adapts to the situation where the tail cable and the wind and water pipe of the transfer machine move forward.

[0044] Furthermore, if Figure 8As shown, the moving mechanism 7 includes a mounting plate 71, and two moving wheels 72 are rotatably mounted on one side of the mounting plate 71, and both of the moving wheels 72 are located on the track 6. In this embodiment, there are at least two moving mechanisms 7 connected to the hydraulic cylinder 5, which are respectively fixed to the cylinder section and the telescopic section of the hydraulic cylinder 5. At the same time, a fixing structure is also provided on the two moving mechanisms 7, and the fixing mechanism includes a micro hydraulic cylinder 711 fixed on the mounting plate 71, and a pressure plate 712 is installed on the output shaft of the micro hydraulic cylinder 711. When the micro hydraulic cylinder 711 is extended, the pressure plate 712 contacts the track 6, so that the moving mechanism 7 is fixed and cannot move. When in use, when the conveyor moves forward, the wrapped cable and the Feng Shui pipe move forward with the conveyor, and at this time, the hydraulic cylinder 5 needs to be extended to push the pulley assembly 4 to move with the movement of the cable. In this case, it is necessary to drive the micro hydraulic cylinder 711 located under the oil cylinder of the hydraulic cylinder 5 so that the pressure plate 712 thereon contacts with the track 6, so that the oil cylinder of the hydraulic cylinder 5 is stationary, and its telescopic section is extended, thereby pushing the pulley assembly 4 to move. When the pulley assembly 4 moves to the specified position, the micro hydraulic cylinder 711 located under the telescopic section of the hydraulic cylinder 5 is started again to make the moving mechanism 7 located under the telescopic section of the hydraulic cylinder 5 stationary. At the same time, the micro hydraulic cylinder 711 located under the oil cylinder of the hydraulic cylinder 5 is reversely started to separate the corresponding pressure plate 712 from the track 6, and then the hydraulic cylinder 5 is reversely started to shrink the hydraulic cylinder 5. At this time, the cylinder section of the hydraulic cylinder 5 moves forward. Repeating the above steps can make the hydraulic cylinder 5 move forward intermittently, and then make the pulley assembly 4 move forward intermittently to adapt to the situation where the tail cable and wind and water pipe of the conveyor and transfer machine move forward.

[0045] Example 5

[0046] like Figure 4 and 5 As shown, a bearing plate structure 8 is fixedly installed on the side of the pulley assembly 4 away from the hydraulic cylinder 5, and the bearing plate structure 8 is fixed to the corresponding moving mechanism 7. The bearing plate structure 8 is used to lift the wrapped cables and wind and water pipes, and the bearing plate structure 8 is more solid under the support of the moving mechanism 7. In actual use, after the conveyor moves forward a long distance, the wrapped cables and wind and water pipes will also move forward a corresponding distance, and their folding parts are farther and farther away from the head of the conveyor, which will cause the cables and wind and water pipes between the head of the conveyor and the pulley assembly 4 to be suspended for a long distance, which is easy to scratch the cables and wind and water pipes below, causing damage. In this embodiment, when the cables and wind and water pipes between the head of the conveyor and the pulley assembly 4 will directly fall on the bearing plate structure 8, the bearing plate structure 8 supports the cables and wind and water pipes to prevent this section of cables and wind and water pipes from scratching the cables below.

[0047] Furthermore, if Fig. 9As shown, the bearing plate structure 8 includes a bearing plate 81, and a plurality of support rollers 82 are provided on the bearing plate 81. When the wrapped cables and the air-water pipes are located on the bearing plate 81, the support rollers 82 will reduce the friction between the two, making the wrapped cables and the air-water pipes easier to move.

[0048] Example 6

[0049] like Fig. 9 As shown, a plurality of connectable cable supporting plates 9 are installed on one side of the transfer machine. The wrapped cables and air-water pipes are initially placed on the cable supporting plates 9. The cable supporting plates 9 support the wrapped cables and air-water pipes, so that the wrapped cables and air-water pipes are laid neatly, which is convenient for subsequent operations.

[0050] Example 7

[0051] like Fig.11 and 12 As shown, a bridge 11 is provided on one side of the support plate 2, and the bridge 11 is used for personnel to cross the transfer machine to enter the working surface. Four sleeves 12 are fixed to the bottom of the bridge 11, and two brackets 13 are fixed on one side of the support plate 2. Screws 14 are threadedly installed on the two brackets 13. The four sleeves 12 are respectively sleeved on the top of the corresponding screws 14, which makes it easy to install the bridge 11. At the same time, the screws 14 are used to facilitate the adjustment of the height of the bridge 11.

[0052] Working principle: When the conveyor moves forward, it drives the wrapped cables and Feng Shui pipes to move through the fixed plate 1, the support plate 2 and the baffle 3. At the same time, the hydraulic cylinder 5 is started to extend the hydraulic cylinder 5, and then the pulley assembly 4 moves in the direction of the conveyor's forward movement. When the moving distance is large, the number of wrapped cables and Feng Shui pipes between the conveyor head and the pulley assembly 4 will gradually increase, and the increased part will fall on the bearing plate structure 8. Before the hydraulic cylinder 5 is started, the fixed structure located under its cylinder section moves to make the corresponding moving mechanism 7 stationary. When the hydraulic cylinder 5 is fully extended and the cylinder section needs to be moved forward, it is necessary to start the fixed structure under the extended section, reversely start the fixed structure under the cylinder section, and then reversely start the hydraulic cylinder 5 to move its cylinder section forward, thereby realizing the advancement of the hydraulic cylinder 5.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
