Abstract
The invention relates to a roller and sliding-plate stepping device of an open-type rock tunneling machine, and relates to a roller and sliding-plate stepping device capable of transporting an open-type rock tunneling machine to an initial tunnel face of a tunnel, which mainly solves the problems that the existing roller and sliding-plate stepping device is large in friction resistance and low in stepping speed when moving forwards. The roller and sliding-plate stepping device comprises a front base and a rear base, wherein a propelling oil cylinder is fixed on the front base, the front base is connected with the rear base through a drawing bar, the rear base is provided with a track, rollers are arranged on the bottom of a rear support, the rollers on the bottom of the rear support are arranged on the track on the rear base, two sides of the front base are respectively provided with two front supporting legs, each front supporting leg comprises a supporting leg shoe, an oil cylinder and a supporting leg upper seat, which are arranged in the vertical direction, an oil cylinder is arranged above each supporting leg shoe, a cylinder rod of each oil cylinder is connected with the corresponding supporting leg shoe, and a cylinder body of each oil cylinder is connected with the corresponding supporting leg upper seat above the cylinder body. The roller and sliding-plate stepping device has advantages of small friction resistance and high stepping efficiency.
Description
Technical field:
The present invention relates to a kind of tunnel that development machine can be transported to start the device of face, specifically relate to a kind of tunnel that open type rock ripper can be transported to and to start the roller sliding plate formula step device of face.
Background technology:
The back carriage of open type rock ripper roller sliding plate formula step device directly contacts with ground in the market, when step device is changed step forward, frictional resistance is very large, stepping rate is slow, efficiency is low, need the propelling cylinder of development machine to coordinate when it is changed step forward to change step, easily damage the propelling cylinder of development machine.In addition this device back carriage to the intensity on ground and flatness requirement high, increase construction cost.
Summary of the invention:
It is little that technical problem to be solved by this invention is to provide frictional resistance when one is changed step forward, and stepping rate is fast, recommends the cooperation of oil cylinder without the need to development machine, to the intensity on ground and the low open type rock ripper roller sliding plate formula step device of flatness requirement.
Above-mentioned purpose is achieved in that it comprises front base and rear base, propelling cylinder is fixed on front base, front base is connected by pull bar with rear base, rear base is provided with track, the bottom of after-poppet is provided with roller, roller bottom after-poppet is placed on the track on rear base, the both sides of front base are respectively equipped with two front leg struts, described front leg strut comprises supporting leg support boots setting up and down, oil cylinder, the supporting leg seat of honour, the top of described supporting leg support boots is oil cylinders, the cylinder bar of oil cylinder is connected with supporting leg support boots, the cylinder body of oil cylinder is connected with the supporting leg seat of honour of the side of being located thereon.
Advantage of the present invention is: be connected with development machine at the supporting leg seat of honour of two front leg struts during work, the rear portion of development machine is placed on after-poppet, the cylinder body of propelling cylinder is connected with development machine, the oil cylinder bar retraction of two front leg struts, two front leg struts are risen, propelling cylinder work on front base, cylinder bar stretches out, development machine is travelled forward on front base, after-poppet is also along with the motion of development machine travels forward in orbit simultaneously, move after a stroke, the oil cylinder bar of two front leg struts stretches out, supporting leg support boots and earth surface, propelling cylinder cylinder bar retraction on front base, front base drives rear base to travel forward a stroke by pull bar, roller is relative with track to roll, complete a step cycle.Due to roller and non-orbiting scroll friction, so decrease frictional resistance, reduce power consumption, less demanding to ground flat degree, reduce cost, structure is simple, stepping efficiency is high, does not need the hydraulic Step Cylinder of development machine to participate in stepping, can avoid the hydraulic Step Cylinder damaging development machine.

Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention:
With reference to Fig. 1,2, it comprises front base 1 and rear base 2, propelling cylinder 3 is fixed on front base, front base is connected by pull bar 4 with rear base, rear base is provided with track 5, the bottom of after-poppet 6 is provided with roller, roller bottom after-poppet is placed on the track on rear base, the both sides of front base are respectively equipped with two front leg struts, described front leg strut comprises supporting leg support boots 7 setting up and down, oil cylinder 8, the supporting leg seat of honour 9, the top of described supporting leg support boots is oil cylinders, and the cylinder bar of oil cylinder is connected with supporting leg support boots, and the cylinder body of oil cylinder is connected with the supporting leg seat of honour of the side of being located thereon.
