Description

Technical Field

[0001] The present invention belongs to the technical field of underground auxiliary transportation equipment in mines, and specifically relates to a mine track vehicle pushing device. Background Art

[0002] In the underground roadway environment of coal mines, there is a common scenario where an overhead suspended track (sky track) runs parallel to a ground transportation track (ground track). In the traditional transportation mode, the equipment on the two tracks operates independently. A single rail hoist system is configured on the sky track for the suspended transportation of light materials or personnel, while on the ground track, mine cars and flatbed trucks still rely on special traction devices such as diesel locomotives and winches to transport heavy equipment (such as hydraulic supports) or coal.

[0003] The flexible lifting ability of the single rail hoist is not used to optimize the transfer process of heavy equipment on the ground track, resulting in a double superposition of low equipment utilization rate and high transportation cost. Summary of the Invention

[0004] The purpose of the present invention is to address the above problems and provide a mine track vehicle pushing device that can push a ground track locomotive through a locomotive running on an overhead suspended track, thereby reducing costs and improving work efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A mine track vehicle pushing device includes a single I-beam track suspended in the air, a driving device, and a carrying trolley; the driving device is movably arranged along the I-beam track; the carrying trolley is connected to the driving device through a connecting rod and is driven by the driving device to move synchronously along the I-beam track;

[0007] A trolley pushing device is arranged below the carrying trolley, which includes a connecting seat, a swing arm, a telescopic arm, a push head, a first telescopic cylinder, and a second telescopic cylinder; the connecting seat is fixedly connected to the lower part of the carrying trolley; the swing arm is hinged to the connecting seat through a hinge shaft; both ends of the first telescopic cylinder are respectively hinged to the connecting seat and the swing arm and are used to drive the swing arm to rotate around the hinge shaft in a vertical plane; the telescopic arm is slidably connected to the swing arm, and both ends of the second telescopic cylinder are respectively hinged to the swing arm and the telescopic arm and are used to drive the telescopic arm to extend and retract along the length direction of the swing arm; the push head is fixedly installed at one end of the telescopic arm away from the swing arm.

[0008] In a possible embodiment, the driving device includes a driving member and at least a pair of driving wheel sets; the driving wheel sets are symmetrically arranged on both sides of the I-shaped track and are in rolling contact with the web surface of the I-shaped track; the power input end of the driving member is externally connected to a power source, and the power output end is connected to the transmission shaft of the driving wheel set to drive the driving wheel set to rotate and drive the driving device to move along the track.

[0009] In a possible embodiment, the driving member is a pneumatic motor, and both the first telescopic cylinder and the second telescopic cylinder are air cylinders; the pneumatic motor, the first telescopic cylinder and the second telescopic cylinder are externally driven by an air source through an air pipe.

[0010] In a possible embodiment, the driving member is a hydraulic motor, and both the first telescopic cylinder and the second telescopic cylinder are hydraulic cylinders; the hydraulic motor, the first telescopic cylinder and the second telescopic cylinder are externally driven by a hydraulic system through an oil pipe.

[0011] In a possible embodiment, a chute extending along the length direction of the swing arm is arranged inside the swing arm, and the telescopic arm is slidably arranged in the chute to telescopically extend along the length direction of the swing arm.

[0012] In a possible embodiment, a first limiting groove extending along the length direction of the swing arm is formed on the side wall of the swing arm; a second limiting groove is arranged along the length direction on the side wall of the telescopic arm; the extending directions of the first limiting groove and the second limiting groove are both consistent with the sliding direction of the telescopic arm; the first limiting rod passes through the first limiting groove and the second limiting groove to limit the sliding distance of the telescopic arm relative to the swing arm.

[0013] In a possible embodiment, a limiting hole is formed on the side wall above the hinge shaft on the connecting seat, and a limiting groove is correspondingly formed on the swing arm. The swing arm is limited by passing a second limiting rod through the limiting hole and cooperating with the limiting groove.

[0014] Advantages of the present invention:

[0015] By using the overhead I-shaped track to carry the driving device and the carrying trolley, and synchronously driving the trolley device on the ground track, the transportation tasks of the overhead track (suspension track) and the ground track (ground track) can be controlled by a single set of equipment. Utilize the flexible movement ability of the overhead track to drive the ground track mine car / flatbed car, without the need for an additional traction device (such as a diesel locomotive), significantly reducing equipment redundancy and solving the problem of low efficiency caused by the independent operation of double-track equipment in the traditional mode.

[0016] The trolley device adopts a combined form of a telescopic arm that can be telescoped in the height direction and a swing arm that can be rotated in the vertical direction, enabling it to avoid when the ground track vehicle is running and at the same time be able to push track vehicles at different heights.

Detailed Description of the Embodiment

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0024] As Figure 1-2 shown, this embodiment provides a mining rail vehicle handling device, which is used to handle mine cars, flatbed cars or other small vehicles running on the ground track. It includes a single I-beam track 50 suspended in the air, a driving device 40 and a carrying trolley 20. The driving device 40 is used to move on the I-beam track 50. The driving device 40 is connected to the carrying trolley 20 through a connecting rod 30. The carrying trolley 20 moves along the I-beam track 50 through the running wheels under the pushing and pulling action of the connecting rod 30.

[0025] Refer to Figure 1 . In this embodiment, a carrying trolley 20 is connected to the front and rear of the driving device 40 through a connecting rod 30 respectively. The carrying trolley 20 includes a frame and wheels arranged on the frame. The paired wheels are arranged on both sides of the I-beam track and run on the upper surface of the lower plate of the I-beam track.

[0026] Refer to Figure 1 、Figure 3 and Figure 4 , in a possible embodiment, a trolley device 10 is provided below the carrier trolley 20. The trolley device 10 includes a connecting seat 16, a swing arm 15, a telescopic arm 13, a first telescopic cylinder 12 and a second telescopic cylinder 11. Among them, the connecting seat 16 is fixedly arranged below the carrier trolley 20. Optionally, the top of the connecting seat 16 is fixed below the carrier trolley 20 through fasteners such as bolts. An articulated shaft 17 is arranged on the connecting seat 16. An articulated hole for arranging the articulated shaft 17 is arranged at the top end of the swing arm 15. The articulated shaft 17 is arranged in the articulated hole. Optionally, the axis of the articulated shaft 17 is arranged parallel to the track line. The swing arm 15 is connected to the connecting seat 16 through the articulated shaft 17. The swing arm 15 can rotate in the roadway width direction in the coal mine. When the swing arm 15 rotates to the horizontal position, the ground rail vehicle can pass normally. The telescopic arm 13 is arranged in the swing arm 15 and can move along the length direction of the swing arm 15. Through the telescoping of the telescopic arm 13 in the swing arm 15, the trolley device can adapt to the pushing of mine cars or flatbed trucks of different heights. Here, the swing of the swing arm 15 is realized by the drive of the first telescopic cylinder 12. The two ends of the first telescopic cylinder 12 are respectively articulated on the connecting seat 16 and the outer wall of the swing arm 15. Through the action of the first telescopic cylinder 12, the swing arm 15 rotates around the axis of the articulated shaft 17. The telescoping of the telescopic arm 13 is realized by the drive of the second telescopic cylinder 11. The two ends of the second telescopic cylinder 11 are respectively articulated on the outer walls of the swing arm 15 and the telescopic arm 13. Through the telescopic action of the second telescopic cylinder 11, the extension length of the telescopic arm 13 is adjusted.

[0027] Reference Figure 3 , in some embodiments, a push head 14 is arranged at the end of the telescopic arm 13. Optionally, the push head 14 includes a cross beam and a vertical plate arranged at the end of the cross beam. By abutting the vertical plate against both ends of the mine car or flatbed truck, the pushing of the rail vehicle is realized.

[0028] Reference Figure 2 , in some embodiments, the driving device 40 includes a driving member and at least a pair of driving wheel sets; the driving wheel sets are symmetrically arranged on both sides of the I-shaped rail 50 and are in rolling contact with the rail surface of the track; the driving member is driven by an external power input, and its power output end is connected to the rotating shaft of the driving wheel set to control the rotation of the driving wheel set, and then drive the driving device to move along the I-shaped rail 50.

[0029] In a possible implementation, the driving member is a pneumatic motor, and the air source of the pneumatic motor is provided by a trachea connected to a compressor. The pneumatic motor is realized by accessing the air source through the trachea. Optionally, the first telescopic cylinder 12 and the second telescopic cylinder 11 are cylinders and are also driven by connecting to an external air source through a trachea. Exemplarily, the driving device 40 here can directly borrow the driving part of a pneumatic monorail crane. The length requirement of the trachea needs to be determined according to the distance to be pushed each time, and multiple air source connectors can be arranged along the roadway.

[0030] In another possible implementation, the driving member is a hydraulic motor, and the hydraulic motor is driven by connecting to a hydraulic system through an oil pipe. Specifically, a hydraulic station is set in a fixed area of the coal mine, and the hydraulic motor is connected to the hydraulic station through an oil pipe. Optionally, the first telescopic cylinder 12 and the second telescopic cylinder 11 are hydraulic cylinders, and they are connected to the hydraulic station through oil pipes. Exemplarily, the driving device 40 here can directly adopt the hydraulic motor driving part of an explosion-proof diesel monorail crane. The length requirement of the oil pipe needs to be determined according to the distance to be pushed each time, and multiple hydraulic stations can be arranged along the roadway.

[0031] Refer to Figure 3 , in some possible embodiments, a chute extending along its length direction is provided in the swing arm 15, and the telescopic arm 13 is slidably arranged in the chute and is moved along the length direction of the swing arm 15 by the action of the second telescopic cylinder 11. In this embodiment, two second telescopic cylinders 11 are symmetrically arranged on both sides of the swing arm 15.

[0032] Refer to Figure 3 and Figure 5 , to prevent the telescopic arm 13 from falling out of the swing arm 15 due to the failure of the second telescopic cylinder 11, a first limiting groove extending along its length direction is opened on the side wall of the swing arm 15, and second limiting grooves are arranged at intervals along the length direction on the side wall of the telescopic arm 13; the extending directions of the first limiting groove and the second limiting groove are both consistent with the sliding direction of the telescopic arm; the first limiting rod 19 passes through the first limiting groove and the corresponding second limiting groove to limit the sliding distance of the telescopic arm 13 relative to the swing arm 15.

[0033] Similarly, as shown in Figure 4 , to prevent the swing arm 15 from rotating due to the failure of the first telescopic cylinder 12, a limiting hole is opened at a position on the side wall of the connecting seat 16 above the hinge shaft 17, and a limiting groove is correspondingly opened on the swing arm 15. The second limiting rod 18 passes through the limiting hole and cooperates with the limiting groove to realize the limit of the swing arm 15 after rotation (horizontal position).

[0034] In some embodiments, connecting lugs 161 are provided on both sides of the connecting seat 16, and corresponding connecting lugs are also provided on the driving device 40, and the two opposite connecting lugs are respectively connected by a connecting rod 30.

[0035] Exemplarily, taking the use of a gas source for driving as an example, when this embodiment is specifically used, first, the drive wheel set of the driving device 40 is clamped on both sides of the web of the I-shaped track 50, and the gas source pipeline is connected to the pneumatic motor, the first telescopic cylinder 12 and the second telescopic cylinder 11; at the same time, the carrier trolley 20 is connected to the driving device 40 through the connecting rod 30. At this time, the push head 14 of the trolley device 10 is initially located at the side avoidance position of the roadway (the swing arm 15 is in a horizontal state).

[0036] Subsequently, start the pneumatic motor, the drive wheel set rolls along the I-shaped track 50, driving the carrier trolley 20 and the trolley device 10 to move synchronously to the target position behind the flatbed truck. Operate the first telescopic cylinder 12 to extend, pushing the swing arm 15 to rotate downward around the horizontal hinge shaft 17 to the working position in the vertical direction.

[0037] Immediately afterwards, operate the second telescopic cylinder 11 to extend, driving the telescopic arm 13 to extend towards the ground track along the chute of the swing arm 15 until the vertical plate of the push head 14 is at the same height as the rear end of the flatbed truck. After the preparatory work is ready, the pneumatic motor of the driving device 40 continuously outputs power and moves forward along the I-shaped track 50, pushing the carrier trolley 20 and the trolley device 10 to move forward as a whole through the rigid transmission of the connecting rod 30. Finally, the vertical plate of the push head 14 pushes the rear end of the flatbed truck, smoothly pushing the ore truck or the flatbed truck along the ground track to the target area.

[0038] After the pushing is completed, first control the telescopic arm 13 to retract by the second telescopic cylinder 11, and then insert the first limit rod 19 through the first limit groove and the second limit groove of the swing arm 15 and the telescopic arm 13 to realize the mechanical limit of the telescopic arm; then operate the first telescopic cylinder 12 to retract, driving the swing arm 15 to rotate upward and reset to the horizontal avoidance position; finally, insert the second limit rod 18 to lock the swing arm 15 to ensure that it is stably in the avoidance state.
