Description

Technical Field

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

[0002] In underground coal mines, it's common to see overhead suspended tracks (overhead rails) running parallel to surface transport tracks (ground rails). Traditionally, these two types of track equipment operate independently. While the overhead rails are equipped with a monorail crane system for suspended transport of light materials or personnel, the mine cars and flatbed trucks on the ground rails still rely on specialized traction devices such as diesel locomotives and winches to transport heavy equipment (such as hydraulic supports) or coal.

[0003] The flexible lifting capacity of the monorail crane has not been used to optimize the transfer process of heavy equipment on the ground rail, resulting in low equipment utilization and a double increase in transportation costs. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide a mining rail vehicle pushing device, which can push the ground rail locomotive by running a locomotive on an aerial suspended track, thereby reducing costs and improving work efficiency.

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

[0006] A mining rail vehicle pushing device comprises a single I-shaped rail suspended in the air, a driving device and a carrying trolley; the driving device is movably arranged along the I-shaped rail; the carrying trolley is connected to the driving device via a connecting rod and is driven by the driving device to move synchronously along the I-shaped rail;

[0007] A trolley device is provided under the carrying trolley, which includes a connecting seat, a swing arm, a telescopic arm, a pushing head, a first telescopic cylinder and a second telescopic cylinder; the connecting seat is fixedly connected to the bottom of the carrying trolley; the swing arm is hinged to the connecting seat through a hinge shaft; the two ends of the first telescopic cylinder are respectively hinged to the connecting seat and the swing arm, for driving the swing arm to rotate in a vertical plane around the hinge shaft; the telescopic arm is slidingly connected to the swing arm, and the two ends of the second telescopic cylinder are respectively hinged to the swing arm and the telescopic arm, for driving the telescopic arm to extend and retract along the length direction of the swing arm; the pushing head is fixedly mounted on the 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 one pair of driving wheel groups; the driving wheel groups are symmetrically arranged on both sides of the I-rail and are in rolling contact with the web surface of the I-rail; the power input end of the driving member is connected to an external power source, and the power output end is connected to the transmission shaft of the driving wheel group to drive the driving wheel group 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 the first telescopic cylinder and the second telescopic cylinder are both pneumatic cylinders; the pneumatic motor, the first telescopic cylinder and the second telescopic cylinder are driven by an external air source through an air pipe.

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

[0011] In a possible embodiment, a slide groove extending along the length direction of the swing arm is provided in the swing arm, and the telescopic arm is slidably provided in the slide groove to be telescopic 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 provided on the side wall of the swing arm; a second limiting groove is provided on the side wall of the telescopic arm along the length direction of the telescopic arm; the extension directions of the first limiting groove and the second limiting groove are consistent with the sliding direction of the telescopic arm; the first limiting groove and the second limiting groove are passed through a first limiting rod to limit the sliding distance of the telescopic arm relative to the swing arm.

[0013] In a possible embodiment, a limiting hole is opened on the side wall above the hinge shaft on the connecting seat, and a corresponding limiting groove is opened on the swing arm. A second limiting rod passes through the limiting hole and cooperates with the limiting groove to achieve the limitation of the swing arm.

[0014] Beneficial effects of the present invention:

[0015] The overhead I-shaped track carries the drive unit and trolley, which in turn drives the trolley on the ground rail. This allows a single set of equipment to simultaneously control the transport tasks of both the overhead rail (suspended track) and the ground rail (ground track). The flexible mobility of the overhead rail drives the ground rail mining cart / flatbed car, eliminating the need for additional traction devices (such as diesel locomotives). This significantly reduces equipment redundancy and addresses the inefficiency caused by the independent operation of dual-track equipment in traditional models.

[0016] The trolley device adopts a combination of a telescopic arm that can be extended and retracted in the height direction and a swing arm that can be rotated in the vertical direction, so that it can avoid ground rail vehicles when they are running, and can also push rail vehicles of different heights.

DETAILED DESCRIPTION

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

[0024] like Figure 1-2 As shown, this embodiment provides a mining rail vehicle handling device for transporting mine cars, flatbed trucks, or other small rail-based vehicles running on ground tracks. The device comprises a single suspended I-rail 50, a drive device 40, and a trolley 20. The drive device 40 is configured to move along the I-rail 50 and is connected to the trolley 20 via a connecting rod 30. The trolley 20 moves along the I-rail 50 via running wheels, driven by the connecting rod 30.

[0025] refer to Figure 1 In this embodiment, a trolley 20 is connected to the front and rear of the driving device 40 via connecting rods 30. The trolley 20 includes a frame and wheels provided on the frame. The wheels are arranged in pairs on both sides of the I-shaped track and run along the lower plate of the I-shaped track.

[0026] refer to Figure 1 、 Figure 3 and Figure 4 In a possible embodiment, a trolley device 10 is provided below the carrying trolley 20, and the trolley device 10 includes a connecting seat 16, a swing arm 15, a telescopic arm 13, and a first telescopic cylinder 12 and a second telescopic cylinder 11. The connecting seat 16 is fixedly provided below the carrying trolley 20. Optionally, the top of the connecting seat 16 is fixed to the bottom of the carrying trolley 20 by fasteners such as bolts. A hinge shaft 17 is provided on the connecting seat 16, and a hinge hole for setting the hinge shaft 17 is provided at the top of the swing arm 15. The hinge shaft 17 is set in the hinge hole. Optionally, the axis of the hinge shaft 17 is set parallel to the track line. The swing arm 15 is connected to the connecting seat 16 through the hinge shaft 17. The swing arm 15 can rotate in the width direction of the tunnel under the coal mine. When the swing arm 15 rotates to a horizontal position, ground rail vehicles can pass normally. The telescopic arm 13 is disposed within the swing arm 15 and is movable along the length of the swing arm 15. The telescopic arm 13's extension and retraction within the swing arm 15 allows the pusher device to accommodate the movement of mine carts or flatbed trucks of varying heights. The swing arm 15 is swung by a first telescopic cylinder 12, the ends of which are hinged to a connecting seat 16 and the outer wall of the swing arm 15, respectively. The first telescopic cylinder 12 causes the swing arm 15 to rotate about the axis of the hinge shaft 17. The telescopic arm 13 is extended and retracted by a second telescopic cylinder 11, the ends of which are hinged to the outer walls of the swing arm 15 and the telescopic arm 13, respectively. The extension and retraction of the second telescopic cylinder 11 allows the telescopic arm 13 to be adjusted in length.

[0027] refer to Figure 3 In some embodiments, a push head 14 is provided at the end of the telescopic arm 13. Optionally, the push head 14 includes a crossbeam and a vertical plate provided at the end of the crossbeam, and the vertical plate is used to abut against both ends of the mine car or flatbed car, thereby realizing the pushing of the rail vehicle.

[0028] refer to Figure 2 In some embodiments, the driving device 40 includes a driving member and at least one pair of driving wheel groups; the driving wheel groups are symmetrically arranged on both sides of the I-rail 50 and are in rolling contact with the rail surface of the rail; the driving member is driven by external power input, and its power output end is connected to the rotating shaft of the driving wheel group to control the rotation of the driving wheel group, thereby driving the driving device to move along the I-rail 50.

[0029] In one possible implementation, the drive element is a pneumatic motor, whose air source is provided by an air pipe connected to a compressor. The pneumatic motor is connected to the air source via the air pipe. Optionally, the first and second telescopic cylinders 12, 11 are pneumatic cylinders, also connected to an external air source via air pipes. For example, the drive unit 40 can be directly adapted from the drive unit of a pneumatic monorail crane. The required air pipe length is determined based on the required distance per movement, and multiple air source connections can be placed along the roadway.

[0030] In another possible implementation, the drive element utilizes a hydraulic motor, which is connected to the hydraulic system via a pipeline. Specifically, a hydraulic station is located in a fixed area of the coal mine, and the hydraulic motor is connected to the hydraulic station via a pipeline. Optionally, the first telescopic cylinder 12 and the second telescopic cylinder 11 utilize hydraulic oil cylinders, which are connected to the hydraulic station via a pipeline. For example, the drive device 40 herein can directly utilize the hydraulic motor drive unit of an explosion-proof diesel monorail crane. The required length of the pipeline is determined based on the required single displacement distance, and multiple hydraulic stations can be deployed along the roadway.

[0031] refer to Figure 3 In some possible embodiments, a slide groove extending along the length of the swing arm 15 is provided in the swing arm 15, and the telescopic arm 13 is slidably disposed in the slide groove and is moved along the length 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 In order to prevent the telescopic arm 13 from falling off the swing arm 15 due to failure of the second telescopic cylinder 11, a first limiting groove extending along the length direction of the swing arm 15 is opened on the side wall of the swing arm 15, and second limiting grooves are arranged at intervals along the length direction of the telescopic arm 13 on the side wall; the extension directions of the first limiting groove and the second limiting groove are consistent with the sliding direction of the telescopic arm; the first limiting groove and the corresponding second limiting groove are penetrated by the first limiting rod 19 to limit the sliding distance of the telescopic arm 13 relative to the swing arm 15.

[0033] Similarly, if Figure 4 As shown, in order to prevent the first telescopic cylinder 12 from failing and causing the swing arm 15 to rotate, a limiting hole is opened on the side wall of the connecting seat 16 above the hinge shaft 17, and a corresponding limiting groove is opened on the swing arm 15. The second limiting rod 18 passes through the limiting hole and cooperates with the limiting groove to achieve the limitation 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 connecting rods 30 .

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

[0036] Then, the pneumatic motor is started to drive the wheel set to roll along the I-shaped track 50, driving the carrying trolley 20 and the trolley device 10 to move synchronously to the target position behind the flatbed truck. The first telescopic cylinder 12 is operated to extend, pushing the swing arm 15 to rotate downward about the horizontal hinge axis 17 to the vertical working position.

[0037] Next, the second telescopic cylinder 11 is extended, driving the telescopic arm 13 along the chute of the swing arm 15 toward the ground track until the vertical plate of the push head 14 is at the same height as the rear end of the flatbed truck. Once the preparations are complete, the pneumatic motor of the drive unit 40 continuously outputs power, moving forward along the I-shaped track 50. The rigid transmission of the connecting rod 30 propels the supporting trolley 20 and the pusher unit 10 forward as a whole. Finally, the vertical plate of the push head 14 pushes the rear end of the flatbed truck, smoothly moving the mine car or flatbed truck along the ground track to the target area.

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

[0039] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0040] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method of the present invention and its core ideas. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures.
