Description

Technical Field

[0001] The present invention relates to the technical field of winches, and more particularly to a hydraulic support winch used for lowering and recovering a hydraulic support. Background Art

[0002] Hydraulic support winches are critical equipment used in underground coal mines to lower and retrieve hydraulic supports. During equipment relocation operations within fully mechanized coal mining faces, the hydraulic support winch is used to pull the wire rope, enabling the movement, lowering, and retrieval of the hydraulic support. As the key component connecting the hydraulic support winch to the hydraulic support, the wire rope bears enormous pulling force, and its safety performance is directly related to the safety and reliability of the entire operation.

[0003] During the use of the existing hydraulic support winch, due to the high humidity of the air in the coal mine and the presence of a large amount of corrosive substances such as acid and alkaline, the wire rope is prone to rust in such an environment. The rust will cause rust spots and pits on the steel wire surface of the wire rope, reducing the effective cross-sectional area of ​​the steel wire and thus weakening the carrying capacity of the wire rope. In addition, the working environment in the coal mine is usually relatively harsh, with a large amount of dust, coal slag and other impurities. These impurities will adhere to the surface of the wire rope, causing the wire rope to frequently contact and rub with the winch's drum, pulley and hydraulic support components, thereby aggravating the degree of wear, reducing the diameter of the wire rope and reducing the strength. When the wear reaches a certain level, and the existing hydraulic support winch weighs more than 30 tons, the wire rope may break, causing serious safety accidents, and the safety is low. In view of this, we propose a hydraulic support winch for lowering and recovering hydraulic supports. Summary of the Invention

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention drives the rotating structure of the four drum assemblies by designing a rotating mechanism. The four steel wire ropes are connected by a rotating hook, so that when the hydraulic support is lowered and recovered, the four steel wire ropes form a four-sided pyramid structure with higher stability. When one of the steel wire ropes is worn and broken, the other three steel wire ropes still form a three-sided pyramid structure, and the hydraulic support can continue to be lowered and recovered without causing safety accidents, thereby solving the technical problem of low safety of the hydraulic support winch.

[0018] 2. The present invention adopts the structural design of the supporting mechanism so that when the rotating hook drives the hydraulic support to be lowered and recovered, the wire rope is straightened, and the rotating chamber provides support for the wire rope. When the drum unit drives the wire rope to move, the supporting roller rotates to reduce friction with the wire rope, thereby reducing the wear of the wire rope. The cross-section of the mounting strip is designed to be an equilateral triangle structure, so that the distance between two adjacent supporting rollers on the same plane is closer, thereby increasing the contact area between the supporting chamber and the wire rope, and reducing the damage to the wire rope when the rotating chamber provides support for the wire rope.

[0019] 3. The present invention adopts the structural design of the guide mechanism and the transmission component, so that when the connecting shaft and the drum unit rotate, the sprocket A drives the sprocket B to rotate through the transmission chain, so that the guide shaft and the guide groove near one end of the fixed seat rotate, so that the guide block moves back and forth in the guide groove, so that the ring slides relative to the guide shaft, the connecting component and the guide component move synchronously, driving the wire rope to move, so that the drum unit will not fold when winding the wire rope.

[0020] 4. The present invention adopts the structural design of the guide assembly so that when the drum unit winds the wire rope, the wire rope moves relative to several parts of the thread groove and the inner surface of the guide ring to form a guide cavity, so that the rotation of the guide ring drives the connecting ring, cleaning brush, oil cotton and connecting rod to rotate. The cleaning brush cleans the surface of the wire rope below, and the oil cotton brushes oil on the surface of the wire rope above to prevent corrosion of the wire rope. The oil on the surface of the wire rope reduces the friction damage caused by contact between the wire rope and other components. When the connecting rod rotates to contact with the ball block, the ball block is separated from the bottom end of the conical groove, and the oil falls from the oil cavity to be absorbed by the oil cotton. When the connecting rod rotates to separate from the ball block, the ball block contacts the bottom end of the conical groove under its own gravity and oil pressure factors to prevent the oil from continuing to fall, thereby realizing automatic intermittent oiling during the movement of the wire rope.

[0051] In an embodiment of the present invention, the guide assembly 67 includes an annular oil tank 671 and a mounting ring block 672 arranged in an upper and lower mechanism. The annular oil tank 671 and the mounting ring block 672 are respectively fixed at both ends of the through groove 665. An annular groove 673 is provided at the bottom end of the annular oil tank 671. The top of the annular groove 673 is provided with a plurality of frustum grooves 674 in an annular equidistant structure. A ball block 675 is movably provided in the frustum groove 674.

[0052] In an embodiment of the present invention, the transmission assembly 7 includes a sprocket A71 and a sprocket B72. The sprocket A71 and the sprocket B72 are arranged in an upper and lower structure in the cavity 13. The connecting shaft 32 penetrates into the cavity 13 near the end of the sprocket A71 and is fixedly connected to the sprocket A71. The guide shaft 60 near the end of the fixed seat 51 penetrates into the cavity 13 and is fixedly connected to the sprocket B72. The sprocket A71 and the sprocket B72 are connected by a transmission chain 73. The present invention adopts the structural design of the guide mechanism 6 and the transmission assembly 7, so that when the connecting shaft 32 and the drum unit 31 rotate, the sprocket A71 drives the sprocket B72 to rotate through the transmission chain 73, so that the guide shaft 60 and the guide groove 64 near one end of the fixed seat 51 rotate, so that the guide block 65 moves back and forth in the guide groove 64, so that the ring 62 slides relative to the guide shaft 60, and the connecting assembly 66 and the guide assembly 67 move synchronously, driving the wire rope 4 to move, so that the drum unit 31 will not fold when winding the wire rope 4.

[0053] Furthermore, the invention designs the structure of the connecting assembly 66 so that when the drum unit 31 winds the wire rope 4 to another winding surface, the connecting block 662 drives the telescopic rod 663, the mounting seat 664 and the guide assembly 67 to rotate relative to the swivel 661 under the action of the wire rope 4 to adapt to the angle of the wire rope 4, thereby reducing the damage to the wire rope 4 caused by the guide assembly 67 when guiding the wire rope 4.

[0054] Moreover, the present invention has a structural design for the guide assembly 67, so that when the drum unit 31 winds the wire rope 4, the wire rope 4 moves relative to the guide cavity formed by the several parts of the thread groove 678 and the inner surface of the guide ring 677, so that the guide ring 677 rotates to drive the connecting ring 681, the cleaning brush 682, the oil cotton 679 and the connecting rod 680 to rotate, the cleaning brush 682 cleans the surface of the wire rope 4 below, and the oil cotton 679 brushes oil on the surface of the wire rope 4 above to prevent the wire rope 4 from being corroded. The oil on the surface of the wire rope 4 reduces the friction damage caused by the contact between the wire rope 4 and other components. When the connecting rod 680 rotates to contact the ball block 675, the ball block 675 is separated from the bottom end of the conical groove 674, and the oil falls from the oil chamber to the oil cotton 679 for absorption. When the connecting rod 680 rotates to separate from the ball block 675, the ball block 675 contacts the bottom end of the conical groove 674 under its own gravity and oil pressure factors, preventing the oil from continuing to fall, thereby realizing automatic intermittent oiling during the movement of the wire rope 4.

[0055] Working principle: This embodiment provides a hydraulic support winch for lowering and recovering a hydraulic support 9. When in use, the motor 25 is controlled to rotate by an external control mechanism, so that the output end of the reduction gear unit 24 drives the rotating shaft 22 and the bevel gear A21 to rotate, thereby rotating the four bevel gears B23, rotating the four connecting shafts 32 and the four drum units 31, and causing the four steel wire ropes 4 to drive the rotating hook 8 to move, thereby lowering and recovering the hydraulic support. At this time, the four steel wire ropes 4 form a quadrangular pyramid structure with higher stability. When one of the steel wire ropes is worn and broken, the other three steel wire ropes still form a triangular pyramid structure, so that the hydraulic support can continue to be lowered and recovered without causing safety accidents, thereby solving the technical problem of low safety of the hydraulic support winch.

[0056] When the rotating hook 8 drives the hydraulic support 9 to be lowered and recovered, the wire rope 4 is straightened, and the rotating chamber provides support for the wire rope 4. When the drum unit 31 drives the wire rope 4 to move, the supporting roller 54 rotates to reduce friction with the wire rope 4, thereby reducing wear on the wire rope 4. The cross-section of the mounting strip 53 is designed to be an equilateral triangle structure, so that the distance between two adjacent supporting rollers 54 on the same plane is closer, which increases the contact area between the supporting chamber and the wire rope 4 and reduces damage to the wire rope 4 when the rotating chamber provides support for the wire rope 4.

[0057] When the connecting shaft 32 and the reel unit 31 rotate, the sprocket A71 drives the sprocket B72 to rotate through the transmission chain 73, so that the guide shaft 60 and the guide groove 64 near one end of the fixed seat 51 rotate, so that the guide block 65 reciprocates in the guide groove 64, so that the collar 62 slides relative to the guide shaft 60, and the connecting assembly 66 and the guide assembly 67 move synchronously, driving the steel wire rope 4 to move, so that the steel wire rope 4 will not be folded when the reel unit 31 is wound around.

[0058] The wire rope 4 moves relative to several parts of the threaded grooves 678 and the inner surface of the guide ring 677 to form a guide cavity, so that the guide ring 677 rotates to drive the connecting ring 681, the cleaning brush 682, the oil cotton 679 and the connecting rod 680 to rotate. The cleaning brush 682 cleans the surface of the wire rope 4 below, and the oil cotton 679 brushes oil on the surface of the wire rope 4 above to prevent corrosion of the wire rope 4. The oil on the surface of the wire rope 4 reduces the friction damage caused by contact between the wire rope 4 and other components. When the connecting rod 680 rotates to contact with the ball block 675, the ball block 675 is separated from the bottom end of the conical groove 674, and the oil falls from the oil cavity to the oil cotton 679 for absorption. When the connecting rod 680 rotates to separate from the ball block 675, the ball block 675 contacts the bottom end of the conical groove 674 under its own gravity and oil pressure factors to prevent the oil from continuing to fall, thereby realizing automatic intermittent oiling during the movement of the wire rope 4.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
