Description

Technical Field

[0001] The invention belongs to the technical field of mining machinery and equipment, and relates to an automatic following and dragging device for a high-pressure hose of a pneumatic monorail crane used in coal mines. Background Art

[0002] In the process of using pneumatic monorail crane to transport materials underground in coal mines, the pneumatic monorail crane is used to transport materials and recycle waste materials to the underground mining face many times per shift. Because the pneumatic monorail crane uses high-pressure gas as a drive, the driving energy is relatively fixed, and high-pressure hoses are used to supply gas. There must be room for movement of the high-pressure hose from the driving device of the pneumatic monorail crane to the compressed air duct main pipe. During each operation of the pneumatic monorail crane, two or more operators must be arranged to follow the car and comb the high-pressure hoses of the pneumatic monorail crane, which is time-consuming and labor-intensive. In addition, when the operators stand behind the monorail crane and follow the car, watch the cars on both sides, and drive in front, the pneumatic monorail crane is likely to collide with it, squeeze the operators, and cause safety accidents. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic following and towing device for the high-pressure hose of a pneumatic monorail crane for coal mines. The towing device automatically combs the high-pressure hose, and there is no need for operators to follow the vehicle to comb the high-pressure hose, so as to solve the problem mentioned in the above background technology that the existing pneumatic monorail crane requires operators to follow the vehicle to comb the high-pressure hose, which is time-consuming, labor-intensive and has the risk of injury.

[0004] The present invention is achieved through the following technical solutions:

[0005] A pneumatic monorail crane high-pressure hose automatic following and dragging device for coal mines, comprising:

[0006] A cable cleat, wherein a plurality of the cable cleats are provided, and the plurality of cable cleats are connected in series through a pin shaft or a bolt to form a cable cleat chain for wrapping a protective high-pressure hose, and a protective channel is formed inside the cable cleat chain. When the pneumatic monorail crane is in operation, when the high-pressure hose is dragged, the cable cleat chain can protect the high-pressure hose to prevent the high-pressure hose from breaking, wearing and winding;

[0007] A U-shaped pipe trough is provided with multiple U-shaped pipe troughs, and multiple U-shaped pipe troughs are connected in series to form a pipe dragging trough for accommodating a cable cleat chain. The cable cleat chain wraps the protective high-pressure hose along the high-pressure hose, and the cable cleat chain is laid in the pipe dragging trough, so as to lay the high-pressure hose in the pipe dragging trough, and one end of the cable cleat chain is fixed to one end of the compressed air duct main pipe, and the other end of the cable cleat chain is fixed to the driving device of the pneumatic monorail crane. With the traction force of the reciprocating movement of the pneumatic monorail crane, the cable cleat chain can be driven to bend and unfold in the pipe dragging trough, and the high-pressure hose can bend and unfold with the cable cleat chain to automatically follow the machine, without the need for special personnel to supervise, saving manpower, and avoiding the occurrence of injuries during transportation by the pneumatic monorail crane.

[0008] Furthermore, a flange is integrally formed on the top of the rear side wall of each U-shaped pipe trough, and a plurality of anchor rods are connected to the flange for suspending the U-shaped pipe trough on the track of the pneumatic monorail crane; the top end of the anchor rod is connected to the track of the pneumatic monorail crane, so that the pipe-drag trough is installed in the air below the track, and the high-pressure hose following the machine in the pipe-drag trough is at a certain height from the ground, which can avoid the high-pressure hose being immersed in water and the high-pressure hose from leaking, thereby ensuring that the pneumatic monorail crane has stable and reliable driving air pressure during operation.

[0009] Furthermore, each of the U-shaped pipe grooves is a U-shaped groove plate structure with a low front and a high rear, which can facilitate workers to clean up debris, dust, etc. in the groove at the front side of the U-shaped pipe groove.

[0010] Furthermore, a drainage hole is provided at the bottom of each U-shaped pipe groove, which can prevent water from accumulating in the U-shaped pipe groove and causing the high-pressure hose to be soaked in water.

[0011] Furthermore, two adjacent U-shaped pipe grooves are detachably connected by bolts, and a pipe groove of appropriate length can be spliced ​​according to the travel length of the pneumatic monorail crane high-pressure hose.

[0012] Furthermore, the cable clamp is an H-shaped cable clamp or a U-shaped cable clamp.

[0013] Furthermore, the width of the cable clamp in the U-shaped tube groove along the front-to-back direction is smaller than the groove width of the U-shaped tube groove and larger than half of the groove width of the U-shaped tube groove, so that the cable clamp chain composed of several cable clamps will not tip over in the tube dragging groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The towing device is used for the automatic following and towing of the air supply high-pressure hose of the pneumatic monorail crane in coal mines. The cable cleat chain is used to wrap the protective high-pressure hose along the high-pressure hose. The cable cleat chain is laid in the towing pipe groove. With the help of the traction force of the pneumatic monorail crane moving back and forth, the cable cleat chain can be driven to bend and unfold in the towing pipe groove. The high-pressure hose can bend and unfold with the cable cleat chain to automatically follow the machine, without the need for special personnel to watch over it, saving manpower and avoiding the occurrence of injuries during the transportation of the pneumatic monorail crane.

[0016] The design of the automatic following and dragging device for the high-pressure hose of the pneumatic monorail crane is based on the actual needs of coal mines, making full use of the side space of the pneumatic monorail crane, and effectively combining the dragging tube groove with the track of the pneumatic monorail crane, thereby realizing the automatic hanging and forward and backward movement of the high-pressure hose of the pneumatic monorail crane. The use of the cable clamp chain in the dragging device effectively protects the high-pressure hose of the pneumatic monorail crane and reduces the loss of the hose. The design of the dragging device is scientific and reasonable, simple and effective, which can improve the standardization level of coal mine safety production, automatically comb the high-pressure hose, and there is no need for operators to follow the vehicle to comb and protect the high-pressure hose, which can reduce the labor intensity of workers, not only improving the safety level, but also ensuring the continuous and stable operation of the pneumatic monorail crane.

[0034] like Figure 4 As shown, each U-shaped pipe groove 3 is provided with a drainage hole 9 at the bottom thereof, so as to prevent water from accumulating in the U-shaped pipe groove 3 and causing the high-pressure hose to be soaked in water.

[0035] Preferably, in this embodiment, Figures 1 to 4 As shown, the cable clamp plate 1 is an H-shaped cable clamp plate, and the width of the cable clamp plate 1 in the front-to-back direction in the U-shaped tube groove 3 is smaller than the groove width of the U-shaped tube groove 3, and larger than half of the groove width of the U-shaped tube groove 3, so that the cable clamp plate chain 2 composed of several cable clamp plates 1 will not tip over in the tube drag groove 4.

[0036] In this embodiment, Figure 5 As shown, the U-shaped pipe groove 3 is made of a steel plate with a length of 3m and a thickness of 2mm, and its groove width a is 200mm, the front side wall height b is 300mm, and the rear side wall height c is 500mm. A height difference of 200mm is formed between the front and rear side walls of the U-shaped pipe groove 3, so that workers can stand in front of the U-shaped pipe groove 3 to clean up the debris, dust, etc. in the groove. The width d of the flange 6 at the top of the rear side wall of the U-shaped pipe groove 3 is 50mm, and the bolt holes 3.1 opened on the groove bottom and the flange 6 at both ends of the U-shaped pipe groove 3 have a diameter of 10mm, the drainage hole 9 opened on the groove bottom of the U-shaped pipe groove 3 has a diameter of 40mm, and the anchor hole 3.2 opened on the flange 6 has a diameter of 21mm;

[0038] The cable cleat chain 2 formed by the cable cleats 1 designed with the above dimensions can be smoothly bent and unfolded in the tube dragging groove 4 formed by the U-shaped tube groove 3 during the following process to protect the high-pressure hose.

[0039] The working principle and technical effects of this embodiment are as follows:

[0040] The dragging device is used for automatically dragging the high-pressure hose of the pneumatic monorail crane of the coal mine. According to the track length of the pneumatic monorail crane, a plurality of U-shaped pipe grooves 3 are connected in series to form a pipe dragging groove 4 of appropriate length. The pipe dragging groove 4 is installed along the track of the pneumatic monorail crane. Specifically, each pipe dragging groove 4 is suspended on the track of the pneumatic monorail crane by two anchor rods 7, so that the pipe dragging groove 4 is installed in the air below the track. According to the length of the high-pressure hose of the pneumatic monorail crane, a plurality of cable clamps 1 are connected in series to form a cable clamp chain 2 of appropriate length, and the high-pressure hose is clamped into the cable In each cable cleat 1 of the cleat chain 2, the cable cleat chain 2 wraps the protective high-pressure hose along the high-pressure hose, and the cable cleat chain 2 is laid in the drag pipe groove 4, so that the high-pressure hose is laid in the drag pipe groove 4, one end of the cable cleat chain 2 is fixed to one end of the compressed air pipe main pipe, and the other end of the cable cleat chain 2 is fixed to the driving device of the pneumatic monorail crane. The high-pressure hose in the drag pipe groove 4 is kept at a certain height from the ground, which can avoid the high-pressure hose from being immersed in water and leaking, thereby ensuring that the pneumatic monorail crane has a stable and reliable driving air pressure when running;

[0041] When the driving device and the trolley of the pneumatic monorail crane move on the track in the direction close to the main pipe of the compressed air duct, they drag one end of the cable cleat chain 2 to move, and the cable cleat chain 2 carries the high-pressure hose and turns back together in the pipe dragging groove 4. When the driving device and the trolley of the pneumatic monorail crane move on the track in the direction away from the main pipe of the compressed air duct, they drag the bent cable cleat chain 2 in the pipe dragging groove 4 to unfold, so as to unfold the high-pressure hose; with the traction force of the reciprocating movement of the pneumatic monorail crane, the cable cleat chain 2 can be driven to bend and unfold in the pipe dragging groove 4, and the high-pressure hose can be bent and unfolded with the cable cleat chain 2 to automatically follow the machine, without the need for special personnel to watch, saving manpower, and avoiding the occurrence of injuries during the transportation of the pneumatic monorail crane. The cable cleat chain 2 is used to provide all-round protection for the high-pressure hose, which not only avoids the wear of the high-pressure hose, but also can properly adjust the bending and relaxation of the high-pressure hose;

[0042] The pipe-drag groove 4 of the automatic following-and-dragging device for the high-pressure hose of the pneumatic monorail crane is processed with the company's waste materials, and the cable clamp 1 is assembled into a cable clamp chain 2 using existing products. During the production period, a total of 20 workers were invested, totaling about 6,000 yuan. After the automatic following-and-dragging device for the high-pressure hose of the pneumatic monorail crane is put into use, the high-pressure hose of the pneumatic monorail crane is saved by about 600 meters of wear and tear each year, which can save about 18,000 yuan in high-pressure hose costs. In daily production, 18 workers / day are used to follow the machine to maintain the high-pressure hose of the pneumatic monorail crane, and 450 workers can be saved in a month based on 25 normal production days. The labor cost alone can save more than 100,000 yuan, and more than 1 million yuan in labor costs can be saved in a year. The towing device has low production cost and high degree of standardization. It can be applied to the automatic following-and-dragging of various pneumatic monorail crane high-pressure hoses to reduce labor costs. The use of the automatic following-and-dragging device for the high-pressure hose of the pneumatic monorail crane has outstanding economic operation and safety benefits in the coal mine production process, and is worthy of promotion and application.
