Description

Technical Field

[0001] This utility model relates to the field of mining auxiliary support technology, specifically to support equipment used in tunneling machinery or mining machinery. Background Technology

[0002] In order to extract the vein rock in a substantially simultaneous manner with such tunneling or mining machinery and to advance safe supports, parallel bolted supports are required.

[0003] Existing support structures are generally integral frame top structures, which are hinged to the top of the machine by two main support columns and controlled by hydraulic telescopic rods. However, when the working equipment is moving, the support structure needs to be retracted. After the support structure is retracted, the excavated coal roof has no auxiliary support, which is prone to collapse and danger. Furthermore, the sides of the excavated mine tunnel are also prone to collapse. The existing support structure has no auxiliary support on both sides of the frame top structure, and the protective support is not comprehensive enough. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing support equipment is inconvenient for supporting the working equipment when it is moving, and is also inconvenient for providing auxiliary support to both sides of the mine tunnel.

[0005] To solve the above problems, the technical solution adopted by this utility model is a support device for tunneling machinery or mining machinery, including a machine frame, with support structures on both sides of the machine frame. The support structure includes a main support column hinged to one side of the machine frame, and a frame top structure at the top of the main support column. The frame top structure includes a support frame rod hinged to the top of the main support column, and several auxiliary top rods fixed on one side of the support frame rod. A hydraulic telescopic rod one is hinged between the support frame rod and the main support column. An auxiliary frame top is hinged on one side of the support frame rod. A hydraulic telescopic rod two is connected between an auxiliary top rod and the auxiliary frame top. A hydraulic telescopic rod three is hinged between the main support column and the machine frame.

[0006] As a further embodiment of this utility model: the top frame structures in the two support structures are staggered, and the auxiliary top rods in the two top frame structures do not interfere with each other, so that one can provide support and the other can retract to provide further support.

[0007] As a further embodiment of this invention, the length of the auxiliary top rod is less than the distance between the two support structures to prevent interference between the two support structures.

[0008] As a further embodiment of this invention, the length of the support frame rod is greater than the length of the main support column, so as to support a larger area.

[0009] As a further embodiment of this utility model: hydraulic telescopic rod one, hydraulic telescopic rod two, and hydraulic telescopic rod three are all connected to an external hydraulic control system.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This patent adds two independent support structures. When the working equipment moves, one of the two independent support structures can provide auxiliary support while the other can be retracted to facilitate the next step of support, thus achieving support even when the working equipment is moving; an auxiliary frame top is added, and the angle of support can be adjusted by the hydraulic telescopic rod.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0020] Combined with appendix Figure 1-4 It can be seen that the equipment includes a machine frame 1, with support structures on both sides of the machine frame 1. The support structures include a main support column 2 hinged to one side of the machine frame 1, and a frame top structure 3 at the top of the main support column 2, which can support the top of the mine. The frame top structure 3 includes a support frame rod 3.1 hinged to the top of the main support column 2. Several auxiliary top rods 3.2 are fixed on one side of the support frame rod 3.1. A hydraulic telescopic rod 4 is hinged between the support frame rod 3.1 and the main support column 2 to drive the support frame rod 3.1 to swing. An auxiliary frame top 5 is hinged to one side of the support frame rod 3.1 to provide auxiliary support for both sides of the mine. A hydraulic telescopic rod 6 is connected between an auxiliary top rod 3.2 and the auxiliary frame top 5 to drive the auxiliary frame top 5 to adjust. A hydraulic telescopic rod 7 is hinged between the main support column 2 and the machine frame 1 to drive the main support column 2 to swing.

[0021] The frame top structures 3 in the two supporting structures are staggered, and the auxiliary top rods 3.2 in the two frame top structures 3 do not interfere with each other, so that one can provide support and the other can retract to provide further support; the length of the auxiliary top rod 3.2 is less than the distance between the two supporting structures to prevent interference between the two supporting structures; the length of the support frame rod 3.1 is greater than the length of the main support column 2 so that it can support a larger area; the hydraulic telescopic rod 1 4, hydraulic telescopic rod 2 6, and hydraulic telescopic rod 3 7 are all connected to the external hydraulic control system.

[0022] The working principle of this application is as follows: When supporting the mine tunnel, the upper side of the frame top structure 3 is in contact with the upper side of the mine tunnel to facilitate support. The auxiliary frame top 5 can provide auxiliary support for both sides of the mine tunnel. When the working equipment needs to be moved, one support structure can be supported while the other support structure is retracted to facilitate the next step of support.

[0023] When the support structure retracts, firstly, the hydraulic telescopic rod 6 in one support structure retracts to allow the auxiliary frame top 5 to swing inside the working equipment. Then, the hydraulic telescopic rod 4 drives the support frame rod 3.1 to swing downwards, so that one end of the support frame rod 3.1 is below the hydraulic telescopic rod 6. Then, the hydraulic telescopic rod 7 extends, allowing the frame top structure 3 to detach from the top of the mine. The working equipment can then move. During the movement, the hydraulic telescopic rod 4 and the hydraulic telescopic rod 7 in another support structure retract. After moving a certain distance, the hydraulic telescopic rods 7 and 4 in the initial support structure are activated to support the top of the mine. Then, the hydraulic telescopic rod 6 is activated to provide auxiliary support for the auxiliary frame top 5.

[0024] If further progress is required, another support structure can be activated to perform the same operation, ensuring that the working equipment also supports the top of the mine shaft as it moves.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
