Embodiment 1

[0036] A tunnel gravel transfer device, comprising: a conveyor belt conveyor, one end of the conveyor belt conveyor is fixed with a belt conveyor fixing frame 40-5, and the bottom of the belt conveyor fixing frame 40-5 is fixed with a belt transport vehicle 40- 9. One end of the transport vehicle 40-9 is provided with a road-rail vehicle set.

[0037] In the above-mentioned first embodiment, the tunnel entrance is blasted by the drill and blast method, and the gravel falls on the tunnel face, and the steel rails are laid in the tunnel, and the belt transport vehicle carries the belt conveyor to move on the steel rails in the tunnel, and Move to the gravel place, and after the belt conveyor is in place, move the road-rail dual-purpose vehicle group to one end of the slag outlet of the belt conveyor through the rails to complete the positioning of the whole set of equipment; the excavator transfers the gravel to the belt conveyor, and the belt conveyor The gravel is transferred ...

Embodiment 2

[0039] Embodiment two: one end of the transport belt conveyor is fixedly provided with a counterweight (40-1); the counterweight fixedly provided at one end of the belt conveyor, its weight is based on the gravel weight dug out by the excavator each time and the weight of the belt conveyor. The moment arm is calculated, and the calculated counterweight is installed on one end of the belt conveyor to keep the two ends of the belt conveyor balanced during the operation.

Embodiment 3

[0040] Embodiment 3: The end of the transport belt conveyor 40 away from the counterweight 40-1 is provided with several anti-deflection rollers 40-6; the anti-deflection rollers are installed on both sides of the belt conveyor, which can effectively control the left and right sides of the belt conveyor. Offset, up and down fluctuations and so on.

Abstract

The invention discloses a tunnel gravel transfer device and a construction method thereof, belongs to the field of shield tunnel transfer, and solves the problems that in the prior art, the gravel transfer efficiency is not high, only one carrier loader can be loaded at a time due to the limitation of the arm length of a mechanical arm of an excavator, and continuous gravel transfer cannot be realized. The tunnel gravel transfer device comprises a belt conveyor, wherein a belt conveyor fixing frame is fixedly arranged at one end of the belt conveyor, a belt conveying vehicle is fixed to the bottom of the belt conveyor fixing frame, and a conveying highway-railway dual-purpose vehicle set is arranged at one end of the conveying vehicle. According to the tunnel gravel transfer device and the construction method thereof, the belt conveyor is matched with the highway-railway dual-purpose vehicle set, so that efficient transfer of gravel is achieved; and through switching of steel rail wheels and highway wheels in the highway-railway dual-purpose vehicle set, the conveying vehicle set can conduct low-energy-consumption transportation on steel rails in a tunnel and can also conduct transportation on a road surface without steel rail laying.

Description

technical field [0001] The invention belongs to the field of shield tunnel transfer, in particular to a tunnel gravel transfer device and its use method Background technique [0002] Tunnels are key and key projects in the construction of roads and railways. With the development of railway construction and the advancement of science and technology, tunnel excavation methods have been developed rapidly. The more commonly used excavation methods are drill and blast method, shield method and roadheader method. Because the drill and blast method has strong adaptability to geological conditions and low excavation cost, it is especially suitable for the construction of hard rock tunnels, broken rock tunnels and a large number of short tunnels. Therefore, the drill and blast method is still a commonly used tunnel excavation method at home and abroad. [0003] For the transshipment technology of tunnel gravel at home and abroad, at present, the excavator mainly excavates the grave...
