Abstract
A pipe conveyer for a mining hydraulic working machine comprises a transmission box and an upper cover plate; two pairs of chain wheels as well as chains on each pair of chain wheels are arranged in the transmission box in parallel, wherein a chain wheel in one pair of chain wheels is provided with a driving chain wheel shaft, a chain wheel in another pair of chain wheels is provided with a driven chain wheel shaft; a driving gear is arranged on the driving chain wheel shaft; a driven gear meshed with the driving gear is arranged on the driven chain wheel shaft; the outer end of the driving chain wheel shaft is connected with a hydraulic clutch driver; a clamping block is fixedly arranged on the outer side of each chain via a small bent plate; a groove is arranged on the outer side of each clamping block; an elastic component is arranged in each groove; and a pipe conveying cavity containing a flexible steel pipe is formed between the opposing clamping blocks on the outer lateral surface. The elastic components arranged in the grooves can effectively increase the friction force between the clamping blocks and the flexible steel pipe, so that a great enough friction force is provided between the flexible steel pipe and the clamping blocks so as to ensure to reliably move forward and lay down the flexible steel pipe. The pipe conveyer has a simple structure, is stable and steady to run, is reliable to work, and provides reliable guarantee for continuous operations.
Description
Technical field
The utility model belongs to tapping equipment technical field under coal mine, particularly the defeated pipe device of a kind of mining water power working rig.
Background technology
The highly gassy mine that China exists is more, and has the advantages that coal seam gas-bearing capacity is high, pressure is large, gas permeability is poor and the extraction difficulty is large.Along with developing rapidly of water jet theory and application technology, both at home and abroad the research of high-pressure water jet boring technology is also quite paid attention to, and dropped into a large amount of human and material resources theory and experimental study have been carried out in high-pressure water jet boring, some can creep into than the water jet rig of hard formation or water jet Aided Machine rig and succeed in developing, and have obtained increasing approval in all kinds of engineerings are used.
The defeated pipe device of existing water jet rig only relies on crawler belt extruding flexible pipe, the frictional force of advancing is provided for flexible pipe, but crawler belt is more pliable and tougher, easily inwardly shrink away from the local of sprocket wheel, can not guarantee the flexible pipe required frictional force of advancing, the phenomenon that flexible pipe and crawler belt skid easily occurs, affect the operating efficiency of continuous pore-forming operation.
The utility model content
The utility model provides the defeated pipe device of mining water power working rig of the large and reliable operation of a kind of simple in structure, frictional force.
for achieving the above object, the technical solution of the utility model is: the defeated pipe device of a kind of mining water power working rig, comprise transmission case body, upper cover plate and lower cover, be provided with side by side the chain on two pairs of sprocket wheels and the every pair of sprocket wheel in transmission case body, wherein a sprocket wheel in pair of sprocket is provided with drive sprocket axle, another is provided with the driven chain wheel shaft to a sprocket wheel in sprocket wheel, drive sprocket axle is provided with driving gear, the driven chain wheel shaft is provided with the driven gear that is meshed with driving gear, driving gear and driven gear are positioned at lower cover, the drive sprocket axle outer end drives with hydraulic clutch and is connected, the chain outside is fixed with fixture block by little bent plate, is provided with groove outside fixture block, is provided with flexible member in groove, forms the defeated tube chamber that contains flexible pipe between the relative fixture block of lateral surface.
Described transmission case body bottom is provided with track by fixed block, and fixed block is provided with the adjustment screw that withstands on track side surfaces, and top, track another side is pressed in the chain inboard.
Described flexible member comprises butterfly spring, rubber spring or helical spring.
Compared with prior art, the utlity model has following advantage:
1, be provided with groove outside fixture block of the present utility model, be provided with flexible member in groove, flexible member is butterfly spring, rubber spring or helical spring, and flexible pipe is clamped between two fixture blocks, can effectively increase the frictional force of fixture block and flexible pipe by flexible member, make and have enough frictional force between flexible pipe and fixture block, put pipe to guarantee that flexible pipe reliably travels forward, simple in structure, stable steady, reliable operation provides reliable guarantee for working continuously.
2, fixture block clamping flexible pipe is outwards carried, and completes to put the pipe action; During closed tube, flexible pipe drives fixture block and chain counter motion, completes the closed tube action, advance or recovery operation easy, make and put pipe and closed tube motion flexibly, be convenient to control, action is not precisely reliably.
3, be provided with track in transmission case body bottom, the top, a side of track is pressed in the inboard of chain, but the stretching chain prevent from that chain is lax to cause flexible pipe to skid, guarantee to put the pipe action accurately errorless.
