Description

Technical Field

[0001] The utility model relates to the field of mine transportation, in particular to an underground self-moving hauling device. Background Art

[0002] The old-fashioned ground rail transportation in coal mines is transported by flatbed trucks pulled by wire ropes, which has safety hazards such as runaway and wire rope breakage. With the development of coal mining and transportation technology, the underground transportation mode has changed from ground rail transportation to roof monorail crane transportation. However, the top and bottom plates of the upper and lower chute of the thin coal seam working face are under great pressure and severely deformed, so it is impossible to install a monorail crane. The height of the chute of the thin coal seam working face is limited, and the single-time transportation capacity of the monorail crane is limited, so it is impossible to simultaneously lift mobile substations, combination switches, power supply cables, accessories and materials to accompany the mining operation. In order to solve these problems, an underground self-moving transport device is proposed. Summary of the invention

[0003] The purpose of the utility model is to provide an underground self-moving transport device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An underground self-propelled transport device includes a front frame-type support hydraulic support, a rear frame-type support hydraulic support, a push cylinder, and a towing platform. The front frame-type support hydraulic support and the rear frame-type support hydraulic support are connected by a push cylinder, the towing platform and the rear frame-type support hydraulic support are connected by a connector, and the towing platform is connected by a linker.

[0006] As a further solution of the utility model: the front frame type support hydraulic support and the rear frame type support hydraulic support are provided with connection holes at the front and rear for connecting the push cylinder and the connector.

[0007] As a further solution of the utility model: the front frame type supporting hydraulic support and the rear frame type supporting hydraulic support are each provided with 4 connection holes at the front and rear.

[0008] As a further solution of the utility model: the towing platform is provided with an anchor point for fixing a steel wire rope or an iron chain.

[0010] As a further solution of the utility model: a plurality of the hauling platforms can be connected in series via a connector.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the device uses hydraulic power, frame-type support hydraulic bracket as anchor point, and hydraulic cylinder as motion medium. The device is easy to use and maintain. After being put into use, rail transportation is abolished, and underground driving accidents are avoided, the safety factor is improved, and the problem of underground trackless tunnel equipment and material transportation is solved. At the same time, the device can perfectly cooperate with mining work, so that mobile substations, combination switches, cables, accessories and materials can be pushed forward together with the working face.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Embodiment 1:

[0017] See also Figures 1 to 4 In an embodiment of the utility model, an underground self-propelled towing device comprises a front frame-type support hydraulic support (1), a rear frame-type support hydraulic support (2), a push cylinder (3), and a towing platform (5), wherein the front frame-type support hydraulic support (1) and the rear frame-type support hydraulic support (2) are connected by the push cylinder (3), the towing platform (5) and the rear frame-type support hydraulic support (2) are connected by a connector (4), and the towing platform (5) and the towing platform (5) are connected by a linker (8).

[0018] The front frame type support hydraulic support (1) and the rear frame type support hydraulic support (2) are provided with connection holes (10) at the front and rear for connecting the push cylinder (3) and the connector (4), and the front frame type support hydraulic support (1) and the rear frame type support hydraulic support (2) are provided with 4 connection holes at the front and rear.

[0019] The hauling platform (5) is provided with an anchor point (7) for fixing a steel wire rope or an iron chain.

[0020] The hauling platform (5) is provided with a modular fixing device (6) and a detachable gantry hanger (10).

[0021] A plurality of the hauling platforms (5) can be connected in series via a connector (8).

[0022] Working principle:

[0023] When in use, in the initial state, the push cylinder (3) is in a retracted state, the front frame-type support hydraulic support (1) is also in a retracted state, and the rear frame-type support hydraulic support (2) is in contact with the tunnel roof and forms a stable force-supported state;

[0024] When the whole device needs to move forward, the push cylinder (3) extends to push the front frame type support hydraulic support (1) forward; when the push cylinder (3) is extended to the right position, the front frame type support hydraulic support (1) is extended upward to contact the tunnel roof and form a stable force support;

[0025] After the front frame type support hydraulic support (1) is supported stably, the rear frame type support hydraulic support (2) is retracted, and the push cylinder (3) is retracted. Since the front frame type support hydraulic support (1) is fixed by force, the rear frame type support hydraulic support (2) and the towing platform (5) are pulled to realize the self-movement of the towing platform. According to actual needs, this action step is repeated.
