Description

Technical Field

[0001] This utility model relates to the field of mine cable traction, and in particular to a coal mine cable traction mechanism. Background Technology

[0002] Mining requires a large amount of mechanical and electrical equipment, necessitating a significant amount of power cables. Moving and transporting these cables is extremely time-consuming and labor-intensive. Most mining operations utilize a monorail system to tow the cables, replacing manual labor and improving efficiency. A monorail system uses a specially designed I-beam suspended above the mine shaft as a track, with various types of lifting vehicles connected together and pulled along the track by traction equipment. The traction power can be provided by wire ropes, diesel engines, batteries, or pneumatic devices.

[0003] For example, patent document CN221118115U discloses a hydraulic single-rail lifting device, which includes a rail, two U-shaped frames installed on the outer side of the rail, a lifting frame installed on the side of each U-shaped frame, a spring installed on the inner side of the lifting frame, a support plate installed on the top of the spring, a shock-absorbing pad installed on the top of the support plate, and lifting plates symmetrically installed in the middle of the lifting frame.

[0004] In the aforementioned device, if a structure with guiding and limiting functions is lacking during the movement of the cable pulled by the single-rail traction mechanism, the cable may detach from the support of the guide wheel during the turning of the single-rail traction mechanism, causing hard friction between the cable and the single-rail traction mechanism or the inner wall of the mine, resulting in damage to the cable sheath.

[0005] For example, patent document CN211670610U discloses a coal mine cable traction mechanism, including a conveying structure, a return winch, and an anti-rotation structure. The upper end of the return winch is fixed with a vertical plate, and the upper end of the vertical plate is fixed with a fixed seat. The inner wall of the fixed seat is uniformly provided with conveying structures, and the sides of the fixed seats between the conveying structures are provided with anti-rotation structures. The above device has a conveying structure set in the inner wall of the fixed seat. The cable surface contacts the rollers. The movement of the cable drives the rollers to roll, which reduces the pulling force during cable laying, reduces labor intensity, and at the same time, the rolling of the rollers will not scratch the cable surface, avoid damage, and improve service life.

[0006] Among existing technologies, the ring-shaped guide wheel assembly is superior in terms of guiding and limiting functions. However, it still has shortcomings in mine cable traction scenarios. First, the ring-shaped guide wheel assembly can only install the cable by passing it through the center, which is not easy to do for heavier cables. Second, the ring-shaped guide wheel assembly is difficult to adjust and clamp according to the cable diameter. Utility Model Content

[0007] The purpose of this utility model is to provide a coal mine cable traction mechanism in order to solve the above-mentioned problems.

[0008] This utility model achieves the above objectives through the following technical solutions:

[0009] A coal mine cable traction mechanism includes a single-rail assembly, on which a hydraulic stepping assembly is mounted. A cable bracket assembly is located behind the hydraulic stepping assembly. The cable bracket assembly includes a bracket structure, with symmetrically arranged guide ring structures mounted on the left and right sides of the lower end of the bracket structure. Each guide ring structure includes a fixed support block, with a lifting frame slidably connected to the middle of the fixed support block. Two symmetrically arranged arc-shaped plates are fixedly connected to the front and rear of the fixed support block. Another inverted arc-shaped plate is mounted on the lifting frame. One side of the lifting frame is hinged to one end of the inverted arc-shaped plate, and the other end of the arc-shaped plate is movably connected to the lifting frame via a pin. A U-shaped wheel set is mounted on the arc-shaped plate, and an adjusting screw is rotatably connected to the lifting frame. The other end of the adjusting screw is threadedly connected to the fixed support block.

[0010] Preferably, the two ends of the U-shaped wheel assembly are fixedly connected to the two ends of the inner side of the arc plate, the support shaft of the U-shaped wheel assembly is made of a tough metal, and the wheel side surface of the U-shaped wheel assembly is made of an arc surface.

[0011] Preferably, the single-rail assembly includes an I-beam, with a lifting lug fixedly connected to the top of the I-beam. The lifting lug is fixedly connected to the mine roof via a standard connector, and symmetrically arranged connecting lugs are fixedly connected to both ends of the I-beam.

[0012] Preferably, the hydraulic stepping assembly includes two first U-shaped frames arranged front and rear. Two power wheels are rotatably connected to the left and right sides of the first U-shaped frames respectively. The cylindrical surface of the power wheels contacts the I-beam. A brake structure is installed on the first U-shaped frame. Two symmetrically arranged first hinge ears are fixedly connected to the bottom of the first U-shaped frame. A stepping hydraulic rod is installed between the two first U-shaped frames through the first hinge ears.

[0013] Preferably, the braking structure includes a clamping link hinged to the outer end of the power wheel, a traction link hinged in the middle of the clamping link, the other end of the traction link hinged to the first U-shaped frame, a clamping hydraulic rod hinged at the lower end between the left and right traction links, and a circular friction plate fixedly connected to the inner end face of the power wheel.

[0015] Preferably, the bottom of the second U-shaped frame has two symmetrically arranged second hinge ears fixedly connected to the front and rear sides. A connecting chain is hinged to the second hinge ear, and the other end of the connecting chain is hinged to the first hinge ear.

[0016] The beneficial effect is that the upper and lower sets of arc plates, with the upper arc plate being able to open and close, make it easy for workers to attach cables to the cable tray assembly. Then, the upper arc plate can be moved by the lifting frame to clamp cables of different diameters.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-8As shown, a coal mine cable traction mechanism includes a single-rail assembly 1, a hydraulic stepping assembly 2 mounted on the single-rail assembly 1, and a cable bracket assembly 3 disposed behind the hydraulic stepping assembly 2. The cable bracket assembly 3 includes a bracket structure, with symmetrically arranged guide ring structures mounted on the left and right sides of the lower end of the bracket structure. The guide ring structures include a fixed support block 307, with a lifting frame 308 slidably connected in the middle of the fixed support block 307. Two symmetrically arranged arc-shaped plates 309 are fixedly connected to the fixed support block 307 front and rear. Another inverted arc-shaped plate 309 is disposed on the lifting frame 308. One side of the lifting frame 308 is hinged to one end of the inverted arc-shaped plate 309, and the other end of the arc-shaped plate 309 is movably connected to the lifting frame 308 via a pin. A U-shaped wheel set 310 is mounted on the arc-shaped plate 309. An adjusting screw 311 is rotatably connected to the upper part of the 8. The other end of the adjusting screw 311 is threadedly connected to the fixed support block 307. In use, the operator removes the pin of the arc plate 309 and the lifting frame 308, and then opens the arc plate 309. In this way, the cable can be placed directly on the two U-shaped wheel sets 310 on the lower side. Next, the arc plate 309 is flipped over and connected to the lifting frame 308 through the pin. This makes it easy to place the cable in the annular guide structure formed by the upper and lower U-shaped wheel sets 310. Next, the operator rotates the adjusting screw 311. The adjusting screw 311 drives the lifting frame 308 to descend through the threaded connection with the fixed support block 307. The lifting frame 308 drives the upper arc plate 309 and U-shaped wheel sets 310 to descend, thereby clamping the cable.

[0033] The two ends of the U-shaped wheel assembly 310 are fixedly connected to the two ends of the inner side of the arc plate 309. The support shaft of the U-shaped wheel assembly 310 is made of a tough metal, and the wheel side of the U-shaped wheel assembly 310 is made of an arc surface. With the above settings, during the process of clamping the cable with the U-shaped wheel assembly 310, the tough metal of the U-shaped wheel assembly 310 will deform when the clamping force is too large, thereby avoiding excessive clamping force and damage to the surface of the cable.

[0034] The single-rail assembly 1 includes an I-beam 101, with a lifting lug 103 fixedly connected to the top of the I-beam 101. The lifting lug 103 is fixedly connected to the mine roof wall through a standard connector. Symmetrically arranged connecting lugs 102 are fixedly connected to both ends of the I-beam 101. When several single-rail assemblies 1 are laid and installed, adjacent I-beams 101 are connected through the connecting lugs 102, and the I-beams 101 are connected to the inner wall of the mine through the lifting lugs 103.

[0035] The hydraulic stepping assembly 2 includes two first U-shaped frames 201 arranged front to back. Two power wheels 202 are rotatably connected to the left and right sides of each first U-shaped frame 201. The cylindrical surfaces of the power wheels 202 contact the I-beam 101. A braking structure is installed on each first U-shaped frame 201. Two symmetrically arranged first hinge ears 207 are fixedly connected to the bottom of each first U-shaped frame 201. A stepping hydraulic rod 206 is installed between the two first U-shaped frames 201 through the first hinge ears 207. The braking structure includes a clamping link 203 hinged to the outer end of the power wheel 202. A traction link 204 is hinged to the middle of the clamping link 203. The other end of the traction link 204 is hinged to the first U-shaped frame 201. The two traction links 206 are connected to the left and right sides of the first U-shaped frame 201. A clamping hydraulic rod 205 is hinged at the lower end between the connecting rods 204. A circular friction plate is fixedly connected to the inner end face of the power wheel 202. In use, the clamping hydraulic rod 205 drives the clamping connecting rod 203 to deflect. During the deflection of the clamping connecting rod 203, the inner wall of the power wheel 202 is driven to clamp the I-beam 101. This can achieve the braking of the first U-shaped frame 201. The rear first U-shaped frame 201 cannot move due to braking. At this time, the stepping hydraulic rod 206 extends to drive the front first U-shaped frame 201 to move. Subsequently, the front first U-shaped frame 201 cannot move due to braking. At this time, the stepping hydraulic rod 206 retracts to drive the rear first U-shaped frame 201 forward. In this way, the hydraulic stepping component 2 can realize the function of driving the cable forward.

[0036] The bracket structure includes a second U-shaped frame 301. Wheels 302 are rotatably connected to the left and right sides of the second U-shaped frame 301. The cylindrical surfaces of the wheels 302 can contact the I-beam 101. A spring damping rod 303 is fixedly connected to the lower end of the second U-shaped frame 301. A horizontal plate 305 is fixedly connected to the movable end of the spring damping rod 303. The left and right ends of the horizontal plate 305 are fixedly connected to two fixed support blocks 307. Two symmetrically arranged second hinge ears 304 are fixedly connected to the front and rear sides of the bottom of the second U-shaped frame 301. A connecting chain 306 is hinged to the second hinge ears 304. The other end of the connecting chain 306 is hinged to the first hinge ear 207. During the forward movement of the hydraulic stepping component 2, the connecting chain 306 drives the cable bracket assembly 3 to move. The spring damping rod 303 absorbs vibrations during movement, preventing the cable from moving violently.

[0037] Working principle: During the installation of several single-rail components 1, adjacent I-beams 101 are connected via connecting lugs 102, and I-beams 101 are connected to the inner wall of the mine via lifting lugs 103. The clamping hydraulic rod 205 drives the clamping connecting rod 203 to deflect. During the deflection of the clamping connecting rod 203, the inner wall of the driving wheel 202 clamps the I-beams 101, thus braking the first U-shaped frame 201. The rear first U-shaped frame 201 cannot move due to braking. At this time, the stepping hydraulic rod 206 extends, driving the front first U-shaped frame 201 to move. Subsequently, the front first U-shaped frame 201 cannot move due to braking. At this time, the stepping hydraulic rod 206 retracts, driving the rear first U-shaped frame 201 forward. During the forward movement of the hydraulic stepping component 2, the connecting... Chain 306 drives cable tray assembly 3 to move. Before use, the operator removes the pins of arc plate 309 and lifting frame 308, and then opens arc plate 309 so that the cable can be placed directly on the two U-shaped wheel sets 310 on the lower side. Next, arc plate 309 is flipped over and connected to lifting frame 308 through pins. This allows the cable to be conveniently placed in the annular guide structure formed by the upper and lower U-shaped wheel sets 310. Next, the operator rotates the adjusting screw 311. The adjusting screw 311 drives the lifting frame 308 to descend through the threaded connection with the fixed support block 307. The lifting frame 308 drives the upper arc plate 309 and U-shaped wheel set 310 to descend, thereby clamping the cable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
