Description

Technical Field

[0001] This invention relates to the field of mining technology, and in particular to a novel single-column support device. Background Technology

[0002] In recent years, with the continuous advancement of coal mining technology and equipment, hydraulic support technology has become increasingly sophisticated and is gradually expanding into non-coal mining industries, such as bauxite mining and other mining operations. Especially in situations with complex geological conditions and varying mining methods, the requirements for support devices also differ. However, the core issues always revolve around safety and efficiency.

[0003] In existing coal mines, hydraulic supports create a flat roof structure after coal is cut underground by mining machines. The top beams of fully mechanized hydraulic supports achieve good roof support, thus providing effective roof protection. However, in some non-coal mines (such as bauxite mining), due to differences in mining processes compared to fully mechanized coal mining, such as blasting or other methods, the resulting roof is highly irregular both laterally and longitudinally. Traditional hydraulic supports provide poor roof support in these cases, making effective roof protection difficult and posing a significant safety hazard.

[0004] How to design a novel single-column support device that is ingeniously designed, simple in structure, and can effectively protect the roof during the production process, achieve good roof support effect, and lay the foundation for safe and efficient production is a technical problem that needs to be solved in the existing technology. Summary of the Invention

[0005] To address the technical problems of poor lateral connection of existing underground roof beams, leakage of gangue between supports, and poor longitudinal connection of roof beams, this invention provides a novel single-column support device. This device features an ingenious design and simple structure, effectively protecting the roof during production and achieving good connection results, thus laying the foundation for safe and efficient production.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a novel single-column support device, comprising a base body, a rear connecting rod, a front connecting rod, a shield beam, a top beam, a front beam mechanism, a column jack, and a liftable lever mechanism; the base body and the rear connecting rod are connected by a second pin, the base body and the front connecting rod are connected by a first pin and a third pin, the shield beam and the rear connecting rod are connected by a fourth pin, the shield beam and the top beam are connected by a fifth pin, the front beam mechanism and the top beam are connected by a sixth pin, the column jack and the base body are connected by a seventh pin and a pressure plate, and the column jack and the top beam are connected by an eighth pin and a pressure block.

[0007] As a further optimization of the aforementioned single-column novel support device, the front beam body mechanism includes a front beam, a side guard plate, a side tilting plate, a first rockfall baffle plate, a side guard jack, a side tilting jack, a stop bar jack, and a front beam jack.

[0008] As a further optimization of the aforementioned single-column novel support device, the front end of the front beam is connected to the side guard plate via the ninth pin, the side of the front beam is connected to the side flap plate via the tenth pin, the middle of the front beam is connected to the rockfall retaining plate via the eleventh pin, the rear end of the side guard jack is connected to the front beam via the fifteenth pin, the front end of the side guard jack is connected to the side guard plate via the fourteenth pin, the bottom of the side flap jack is connected to the front beam via the thirteenth pin, the top of the side flap jack is connected to the side flap plate via the twelfth pin, the stop bar jack is connected to the rockfall retaining plate via the sixteenth pin, the stop bar jack is connected to the front beam via the seventeenth pin, the front end of the front beam jack is connected to the front beam via the eighteenth pin, and the rear end of the front beam jack is connected to the top beam via the nineteenth pin.

[0009] As a further optimization of the above-mentioned single-column novel support device, the liftable lever mechanism includes a rock-blocking plate base, a second rock-blocking plate, and a lifting jack.

[0010] As a further optimization of the above-mentioned single-column new support device, the base of the rock-blocking plate is connected to the second rock-blocking plate through a slide rail, the bottom of the lifting jack is connected to the base of the rock-blocking plate through the twentieth pin, and the lifting jack is connected to the second rock-blocking plate through the twenty-first pin, forming a flip-up structure to protect the lifting jack.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This invention relates to a novel single-column support device, which differs from traditional hydraulic supports and is suitable for underground mining in non-coal mines. Its main features include: 1. Single-column structure design: The single-column design reduces the width of the top plate of the entire device. At the same time, the top beam is designed as a hinged top beam with a front beam, and side flaps are set on the outside of the top beam and the front beam. This design achieves a better connection effect for uneven top plates.

[0012] Second, the new front beam design: The front end of the front beam connects to the side guard plate, the rear end connects to the top beam, the sides connect to the side flaps, and the middle connects to the tiltable retaining wall. These structures are connected to the front beam via jacks. This structural design ensures effective roof connection while further improving operational safety.

[0013] Third, the liftable rock-blocking device: The liftable rock-blocking device and the flip-up rock-blocking plate on the top beam form a "protective wall", which not only protects the column jack from damage, but also better protects the safety of the operators. Attached Figure Description
