Crawler walking cave mouth protecting top shed for outdoor slope coal excavation

Abstract

The invention belongs to the technical field of top shed protecting equipment, and particularly relates to a crawler walking cave mouth protecting top shed for outdoor slope coal excavation. The top shed comprises an arc-shaped impact resistant top shed, a supporting frame and self-walking rotary devices. The two ends of the arc-shaped impact resisting top shed are hinged to the supporting frame,the arc-shaped impact resisting top shed is composed of a protecting top plate, side protecting plates and a telescopic oil cylinder; the supporting frame comprises a framework and two telescopic height adjusting mechanisms, the lower ends of the height adjusting mechanisms are provided with the self-walking rotary devices, the self-walking rotary devices comprise crawler walking mechanisms and rotary mechanisms, and the steering of the crawler walking mechanisms can be achieved through the rotary mechanisms to allow the whole protecting top shed to move from a current cave mouth working surface to the next cave mouth working surface reliably and rapidly. By means of the combination of the above mechanisms, the effective protection of coal excavating equipment performed by the crawler walking cave mouth protecting top shed for outdoor slope coal excavation when outdoor slope coal excavating is conducted is achieved, the safe and efficient operation of the coal excavating equipment is ensured, and the safety of workers can be protected.

Description

technical field [0001] The invention belongs to the technical field of ceiling protection equipment, and in particular relates to a protective ceiling for crawler belts in open-pit side coal mining. Background technique [0002] At present, the coal mining protection devices on the open-pit side of coal mining equipment are mainly constructed of simple steel plates. The protection devices constructed in this way have low reliability and have relatively serious safety hazards. When the protective device is transferred from the tunnel opening, it is necessary to use external equipment to drag and pull under the side rail, which not only affects the protective strength of the entire device, but also has low efficiency; at the same time, the protective roof also needs to ensure that the coal mining equipment can move from the middle of its protected area. Passed smoothly, so the ceiling design is relatively high, and the high ceiling cannot guarantee better strength and protecti...

Problems solved by technology

[0002] At present, the coal mining protection devices on the open-pit side of coal mining equipment are mainly constructed of simple steel plates. The protection devices built in this way have low reliability and pose serious safety hazards.

When the protective device is transferred from the tunnel opening, it is necessary to use external equipment to drag and pull under the side rail, which not only affects the protective strength of the entire device, but also has low efficiency; at the same time, the protective roof also needs to ensure that the coal mining equipment can move from the middle of its protected area. Passed smoothly, so the ceiling design is relatively high, and the high ceiling cannot guarantee better strength and protection effect; the simple protective device has poor impact resistance and cannot form an effective buffer; the built protective device has poor adaptability, Unable to form a good cooperation with the mountain
