Description

A type of integrated support and dismantling winch device for underground coal mines Technical Field

[0001] This invention relates to the field of winches used in underground coal mines, specifically to an integrated support and dismantling winch device for underground coal mines. Background Technology

[0002] Winches are widely used in mechanized coal mining faces in underground coal mines, and their applications are becoming increasingly diverse. They can be used as return winches for the installation of working faces and the retraction of hydraulic supports. They can also be used as transport winches, installed in roadways for the relocation of equipment in fully mechanized mining faces such as uphill, downhill, and horizontal roadways, as well as the handling of various other electromechanical equipment. Furthermore, they can replace dispatch winches and transport winches for the dispatching of mine cars and the transportation of materials at mining faces and on the coal mine surface. Therefore, winch devices are required in underground coal mine retreat operations.

[0003] Existing underground winches in coal mines require multiple hydraulic single-pillar supports as pressure levers, necessitating the replenishment of hydraulic fluid every shift. When the winch is under excessive tension, uneven pressure on the individual supports can lead to runaway. Furthermore, winches are frequently used during the retreat of the longwall mining face, but the current winches have poor maneuverability, requiring frequent movement. Each movement necessitates coordination with other equipment and the disassembly of the hydraulic single-pillar supports, resulting in high workload, time-consuming and labor-intensive operations, and reduced work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated support and withdrawal winch device for underground coal mines, in order to solve the problems mentioned in the background art, which involve high work intensity, time and labor consumption, and reduced work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a winch device for underground coal mines, comprising a box-type base and a mounting base. The front and rear ends of the mounting base are fixedly connected to the box-type base. A drive motor is fixedly installed on the right side of the upper end of the mounting base. A winch disc is provided on the left side of the upper end of the box-type base. A mounting seat is fixedly connected to the left end of the mounting base. A guide frame is fixedly connected to the upper end of the mounting seat. A protective frame is fixedly connected to the right end of the mounting base. A hydraulic drive device is fixedly installed on the upper end of the box-type base. A top beam frame is installed on the upper end of the hydraulic drive device. Anti-slip contact seats are provided on the upper surface of the top beam frame, and the anti-slip contact seats are evenly spaced. A lifting groove is opened at the lower end of the inner side of the box-type base, and a moving wheel is provided in the lifting groove. A pressure sensor is provided on the side of the upper end of the top beam frame. A limit component is installed on the left end of the mounting base.

[0006] The above technical solution involves a box-type base that contacts the ground, and a hydraulic drive device that lifts the top beam frame to contact the top of the mine, achieving self-anchoring and fixing. This replaces a single hydraulic rod, reduces the difficulty of equipment operation and use, and ensures safety.

[0007] Preferably, both the guide frame and the protective frame are U-shaped, and the upper end of the protective frame is equipped with an audible and visual alarm.

[0008] The above technical solutions facilitate the use of winch cables through the guide frame and improve safety by providing alerts during underground operations through audible and visual alarms.

[0009] Preferably, two hydraulic drive devices are symmetrically arranged about the vertical center line of the box-type base, and the output ends of the two hydraulic drive devices are fixedly connected to the left and right ends of the top beam frame, respectively.

[0010] By using the above technical solutions, replacing multiple hydraulic individual props with an integrated hydraulic drive device, the efficiency of retraction is greatly improved, the maintenance difficulty of the hydraulic system is reduced, the workload is reduced, the number of personnel required during use is reduced, and labor costs are lowered.

[0011] Preferably, the top beam frame has a U-shaped structure design, and two top beam frames are provided on the front and rear sides of the mounting base, with a connecting plate between the two top beam frames, and a lighting lamp is provided at the lower end of the connecting plate.

[0012] The above technical solution facilitates the self-anchoring of the winch by having the top integral beam frame in contact with the bottom of the well. Meanwhile, pressure sensors on both sides detect the stress state on both sides of the top beam frame. When the pressure on one side decreases, information can be sent in time to facilitate maintenance and avoid the risk of "runaway".

[0013] Preferably, two lifting slots are provided on the left and right sides of the box-type base, and lifting cylinders are fixedly connected to the inner side of the box-type base on both the left and right sides of the lifting slots.

[0014] Preferably, a fixed plate is provided at the upper end of the movable wheel, and the output ends of the two lifting cylinders are respectively fixedly connected to the left and right ends of the fixed plate.

[0015] Through the above technical solutions, when the winch needs to be moved, the lifting cylinder drives the moving wheels to move downwards and contact the ground, thereby facilitating the movement of the entire device, reducing the labor intensity of the operators, and improving work efficiency.

[0016] Preferably, two pressure sensors are provided on the left and right sides of the top beam frame, and the pressure sensors are electrically connected to the audible and visual alarm.

[0017] Preferably, the limiting component includes a gripping plate, the lower end of which is fixedly connected to a spike tooth seat, the spike tooth seats being evenly distributed, and the upper end of the gripping plate being movably connected to a mounting base via a telescopic cylinder, wherein two telescopic cylinders are provided.

[0018] Through the above technical solutions, during the anchoring of the device, the position of the gripping floor is adjusted by the telescopic cylinder so that the gripping floor contacts the ground and the spike tooth seat is inserted into the ground, increasing the stability of the anchoring and thus protecting one side of the device and reducing the risk of "runaway".

[0019] Compared with related technologies, the integrated support and dismantling winch device for underground coal mines provided by this invention has the following beneficial effects:

[0020] This invention provides a hydraulic drive device, a top beam frame, and moving wheels. When using a winch in an underground coal mine, the winch contacts the ground via a box-type base, and the hydraulic drive device pushes the top beam frame to rise and contact the mine roof, achieving self-anchoring. The overall operation is convenient and fast. During winch use, lighting is provided by a lamp, and the anti-slip contact seat on the top of the top beam frame increases stability. Pressure sensors on both sides can detect pressure changes, and when the anchoring stability changes, a timely warning can be issued to the personnel to check, preventing "runaway" phenomena and increasing safety. A limit component is set, and the position of the gripping floor is adjusted by a telescopic cylinder, so that the gripping floor contacts the ground, and the spike tooth seat inserts into the ground, increasing the stability of the anchoring. At the same time, when movement is required, the hydraulic drive device retracts, and the lifting cylinder drives the moving wheels to move downwards and contact the ground, thereby facilitating the movement of the entire device, reducing the labor intensity of the operators, and improving work efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-6. A winch device for underground coal mines includes a box-type base 1 and a mounting base 2. The box-type base 1 is fixedly connected to both the front and rear ends of the mounting base 2. A drive motor 3 is fixedly installed on the right side of the upper end of the mounting base 2. A winch disc 4 is provided on the left side of the upper end of the box-type base 1. A mounting seat 5 is fixedly connected to the left end of the mounting base 2. A guide frame 6 is fixedly connected to the upper end of the mounting seat 5. A protective frame 7 is fixedly connected to the right end of the mounting base 2. A hydraulic drive device 8 is fixedly installed on the upper end of the box-type base 1. A top beam frame 9 is installed on the upper end of the hydraulic drive device 8. Anti-slip contact seats 10 are provided on the upper surface of the top beam frame 9. The anti-slip contact seats 10 are evenly distributed. A lifting groove 11 is opened at the lower end of the inner side of the box-type base 1. A moving wheel 12 is provided in the lifting groove 11. A pressure sensor 13 is provided on the side of the upper end of the top beam frame 9. A limit component 14 is installed on the left end of the mounting base 2.

[0030] Both the guide frame 6 and the protective frame 7 are designed with a U-shaped structure, and the upper end of the protective frame 7 is equipped with an audible and visual alarm 71;

[0031] Two hydraulic drive devices 8 are symmetrically arranged about the vertical center line of the box base 1, and the output ends of the two hydraulic drive devices 8 are fixedly connected to the left and right ends of the top beam frame 9 respectively.

[0032] Specifically, as shown in Figures 1, 2 and 3, the guide frame 6 facilitates the use of the winch cable, and the audible and visual alarm 71 provides a warning during downhole operations, improving safety. At the same time, the integrated hydraulic drive device 8 replaces multiple hydraulic single props, greatly improving the efficiency of retraction, reducing the difficulty of maintenance of the hydraulic system, reducing workload, reducing the number of personnel required during use, and lowering labor costs.

[0033] Example 2: There are two lifting slots 11 located on the left and right sides of the box base 1. Lifting cylinders 101 are fixedly connected to the inner side of the box base 1 on both the left and right sides of the lifting slots 11.

[0034] A fixed plate 121 is provided on the upper end of the movable wheel 12, and the output ends of the two lifting cylinders 101 are fixedly connected to the left and right ends of the fixed plate 121 respectively.

[0035] Specifically, as shown in Figures 1, 2 and 4, when the winch needs to be moved, the lifting cylinder 101 drives the moving wheel 12 to move downwards and contact the ground, thereby facilitating the movement of the entire device, reducing the labor intensity of the operators, and improving work efficiency.

[0036] Example 3: The top beam frame 9 has a U-shaped structure design. There are two top beam frames 9 located on the front and rear sides of the mounting base 2, and a connecting plate 91 is provided between the two top beam frames 9. A lighting lamp 92 is provided at the lower end of the connecting plate 91.

[0037] Two pressure sensors 13 are installed on the left and right sides of the top beam frame 9, and the pressure sensors 13 are electrically connected to the audible and visual alarm 71.

[0038] Specifically, as shown in Figures 1, 3 and 5, the top integral beam frame 9 contacts the top of the well, facilitating the self-anchoring of the winch. Meanwhile, the pressure sensors 13 on both sides sense the stress state on both sides of the beam frame 9. When the pressure on one side decreases, information can be sent in time to facilitate maintenance and avoid the risk of "runaway".

[0039] Example 4: The limiting component 14 includes a gripping plate 141, and a nail tooth seat 142 is fixedly connected to the lower end of the gripping plate 141. The nail tooth seats 142 are evenly distributed. The upper end of the gripping plate 141 is movably connected to the mounting base 2 through a telescopic cylinder 143. Two telescopic cylinders 143 are provided.

[0040] Specifically, as shown in Figures 1, 2 and 6, during the anchoring of the device, the position of the gripping floor 141 is adjusted by the telescopic cylinder 143 so that the gripping floor 141 contacts the ground and the nail tooth seat 142 is inserted into the ground, increasing the stability of the anchoring and thus protecting one side of the device and reducing the risk of "runaway".

[0041] Working principle: The box-type base 1, mounting base 2, and bottom are in contact. A hydraulic drive device 8 drives the top beam 9 to move upwards, causing the top beam 9 to contact the top, achieving self-anchoring. A telescopic cylinder 143 adjusts the position of the gripping plate 141, ensuring it contacts the ground. The nail tooth seat 142 inserts into the ground, increasing anchoring stability. The hydraulic drive device 8 replaces multiple hydraulic cylinders, simplifying control and operation, reducing workload. Anti-slip contact seats 10 further enhance contact stability. Simultaneously, pressure sensors 13 on both sides detect the pressure on both sides of the top beam 9. When the pressure on one side decreases, a message can be sent in a timely manner to facilitate maintenance and prevent runaway, thus increasing safety. During winch operation, lighting is provided by lamp 92 and an audible and visual alarm 71 provides an audible and visual warning, ensuring operational safety. When the winch needs to be moved, the hydraulic drive device 8 retracts, separating the top beam frame 9 from the top. The lifting cylinder 101 then moves the fixed plate 121, bringing the moving wheels 12 into contact with the ground. This facilitates the overall movement of the device, reduces the labor intensity of operators, and improves work efficiency.
