Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary operation vehicles in coal mines, and specifically discloses a narrow floating shovel tracked anti-impact support tractor. Background Technology

[0002] Hydraulic anti-rock pressure supports (hereinafter referred to as anti-rock pressure supports) are widely used in the two roadways of fully mechanized mining faces in mines with rock bursts, effectively protecting the roadway roof. Currently used anti-rock pressure supports mostly employ a four-column support structure, which is significantly greater than ordinary single or unit-type supports in terms of support resistance and weight, typically weighing around 20 tons. Currently, the alternating forward movement of anti-rock pressure supports is mainly done manually, using manual track laying and winch wire rope traction. This process is inefficient, labor-intensive, and physically demanding. During the face advancement, repeated movement and fixing of the winch are required, making the process complex and cumbersome, and posing a high risk of accidents due to winch wire rope traction. Furthermore, the narrow passageways after the anti-rock pressure supports are installed in the roadways, only 2.1-2.3 meters wide, prevent the entry of heavy-duty transport vehicles commonly used underground, hindering the promotion of mechanized construction. In addition, due to the narrow driving lanes in the anti-impact support area, wheeled transport vehicles have difficulty entering the end of the working face for material transportation, making it difficult to replace and transport the motors, reducers, and large parts of various production equipment within the 100-meter area where the anti-impact support is located.

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This embodiment provides a narrow-type floating shovel tracked anti-impact support tractor, including a main frame 1, an explosion-proof diesel engine system 2, a hydraulic control system 3, a cab 4, a hydraulic oil tank 5, a traction hydraulic winch 6, a traction circular chain 7, a tracked walking unit 8, a floating shovel mechanism 9, a counterweight 10, and a remote controller 11. It realizes the shoveling and moving of anti-impact supports in the longwall mining face roadway, effectively improving the moving efficiency of large-tonnage anti-impact supports, and also has the function of handling production materials in the working face, reducing the labor intensity of workers and reducing safety risks.

[0019] It adopts a tracked walking method, is powered by an explosion-proof engine, and has a narrow body design with an overall width of less than 1.6m, which can effectively pass through traffic channels.

[0020] The tracked running gear 8 is a four-wheel and one-track structure, including track frame, drive sprocket, guide wheel, track roller, carrier roller, track tensioning assembly, etc., and the power is an integrated structure of drive motor and reducer.

[0021] Two sets of tracked walking parts 8 are arranged on both sides of the main frame 1; the explosion-proof diesel engine system 2, hydraulic control system 3, hydraulic oil tank 5, and cab 4 are arranged on the main frame 1 from back to front; the floating shovel mechanism 9 is arranged at the front of the main frame 1; and the counterweight block 10 is arranged at the lower part of the main frame 1.

[0022] The floating shovel mechanism includes a shovel bending connecting rod 9.1, a leveling cylinder 9.2, a shovel assembly 9.3, and a lifting cylinder 9.4. The shovel assembly 9.3 includes an L-shaped shovel body 9.3.1, a leveling connecting ear 9.3.4, and a lifting connecting ear 9.3.5. The leveling connecting ear 9.3.4 and the lifting connecting ear 9.3.5 are located on the vertical plate of the L-shaped shovel body 9.3.1, with the leveling connecting ear 9.3.4 positioned above the lifting connecting ear 9.3.5. The two ends of the shovel bending connecting rod 9.1 are hinged to the main frame 1 and the lifting connecting ear 9.3.5, respectively. The two ends of the leveling cylinder 9.2 are hinged to the main frame 1 and the leveling connecting ear 9.3.4, respectively. The two ends of the lifting cylinder 9.4 are hinged to the main frame 1 and the shovel bending connecting rod 9.1, respectively.

[0023] The hydraulic control system 3 controls the lifting cylinder 9.4 and the leveling cylinder 9.2 to achieve both active and passive movements. When transporting the anti-impact bracket, the lifting cylinder 9.4 and the leveling cylinder 9.2 are in passive mode, and the L-shaped shovel body 9.3.1 is placed on the ground and towed by the tracked walking unit 8, thus achieving the traction and transportation of the anti-impact bracket 100. When the machine is traveling unloaded or transporting other parts, the lifting cylinder 9.4 and the leveling cylinder 9.2 are actively controlled to lift the L-shaped shovel body 9.3.1 off the ground, completing the transport operation.

[0024] In the aforementioned narrow-type floating shovel tracked anti-collision bracket tractor, two sets of lifting connecting ears 9.3.5 are symmetrically arranged on both sides of the centerline of the L-shaped shovel body 9.3.1, and two sets of leveling connecting ears 9.3.4 are symmetrically arranged on both sides of the lifting connecting ears 9.3.5. This positions the shovel bending connecting rod 9.1 and the lifting cylinder 9.4 in the middle of the width, and the leveling cylinder 9.2 on both sides of the shovel assembly 9.3, thus better stabilizing the lifting and lowering action of the L-shaped shovel body 9.3.1.

[0025] In the aforementioned narrow-type floating shovel tracked anti-collision bracket tractor, the shovel assembly 9.3 further includes sliding rollers 9.3.2, pusher cylinders 9.3.3, and unloading pusher plates 9.3.6. Sliding rollers 9.3.2 are rotatably arranged on the transverse plate of the L-shaped shovel body 9.3.1 to ensure smooth loading and unloading of the anti-collision bracket 100. Pusher cylinders 9.3.3 are arranged on both sides of the vertical plate. The unloading pusher plate 9.3.6 is located inside the L-shaped shovel body 9.3.1 and is connected to the piston rod of the pusher cylinder 9.3.3. The simultaneous action of the two pusher cylinders 9.3.3 realizes the longitudinal extension of the unloading pusher plate 9.3.6. The pusher cylinders 9.3.3 are arranged on both sides of the track travel section 8, effectively increasing the extension stroke of the pusher cylinders 9.3.3, facilitating the loading and unloading of the anti-collision bracket 100.

[0026] In the aforementioned narrow floating shovel tracked anti-impact bracket tractor, the end of the transverse plate in the L-shaped shovel body 9.3.1 is provided with a guide slope, which facilitates the shovel installation of the anti-impact bracket 100.

[0027] A traction hydraulic winch 6 is installed above the leveling cylinder 9.2; a traction ring chain 7 is wound around the traction hydraulic winch 6 and used to drag the anti-impact bracket 100 onto the L-shaped shovel body 9.3.1. The traction hydraulic winch 6 is a hydraulic motor-driven sprocket structure, with two sets arranged side by side at the front end of the main frame 1. When pulling the anti-impact bracket 100, the traction ring chain 7 passes through the middle channel of the anti-impact bracket 100 for fixation. During the traction and dragging process of the anti-impact bracket 100, the traction ring chain 7 remains in a fixed state.

[0028] The aforementioned narrow-type floating shovel tracked anti-impact bracket tractor uses both on-board and remote control methods. When the equipment is moving and towing the anti-impact bracket 100, it travels backwards using remote control 11, improving personnel safety. When the equipment is unloaded, on-board and remote control can be freely selected.

[0029] The aforementioned narrow-type floating shovel tracked anti-impact bracket tractor has the following innovations: 1. The narrow body structure design of the whole machine takes into account the large weight of the anti-impact bracket 100. It adopts an explosion-proof engine drive and crawler walking to ensure passage space. The floating shovel mechanism is arranged at the front of the main frame 1 to facilitate the loading, unloading and dragging of the anti-impact bracket 100. At the same time, the floating shovel mechanism can be used for shoveling operations such as production materials. 2. The floating shovel mechanism is designed with a shovel bending connecting rod 9.1, a lifting cylinder 9.4, and a leveling cylinder 9.2. It can control the L-shaped shovel body 9.3.1 to achieve floating follow-up action, and can also perform active lifting action. 3. The L-shaped shovel body 9.3.1 is equipped with sliding rollers 9.3.2 to reduce the shovel loading resistance of the anti-impact bracket 100, and integrates an unloading push plate 9.3.6. The extension of the unloading push plate 9.3.6 is controlled by the push plate cylinder 9.3.3, which is more conducive to the unloading of loaded materials; 4. Operation method: When the anti-impact support is pulled 100, the L-shaped shovel body 9.3.1 is placed on the ground and dragged. When loading materials, the L-shaped shovel body 9.3.1 is lifted and loaded.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
