The high inclination-angle development machine of climbing apparatus is helped, belongs to development machine equipment technology field.
Background technology
Development machine is the machine for digging straight underground passage, is divided into open type development machine and shield formula development machine, is led to
Often include walking mechanism, operating mechanism, shipment activity and transferring mechanism composition, as walking mechanism is pushed ahead, operating mechanism
In the continuous fractured rock of cutting head, and detritus is transported, have the advantages that safe efficient and good into lane quality, particularly hang
Road headers, it integrates the functions such as cut, shipment, walking, operation, is mainly used in the underground of cut arbitrary shape section
Rock, coal or alternate heading.
During the larger raise advance in inclination angle, the downslide that development machine can be produced by deadweight, downslide is not only resulted in
The cutting efficiency of development machine declines, cannot even advance, and serious meeting causes security incident, therefore the applicable work of development machine
Make inclination angle general within ± 16 °, tunnel inclination angle surpasses generally to be blown out using hand-holing when going beyond the scope carries out excavation operation
Big gun pick mode, big gun pick operation is not only dangerous very high but also drivage efficiency is relatively low, if getting working face be located under water body,
Under building and railway under " under three " getting working face when forbid big gun dig, tunnel digging angle can only be changed, not only increase
Plus workload, and reduce the exploited length in tunnel, in turn result in the waste of coal resources.

Slope ability, first control control telescopic supporting rod 61 can launch to stretch out to be supported on back, then control row before climbing
The support bar for walking control telescopic supporting rod 61 while hydraulic motor and process auxiliary drive hydraulic motor 731 together export power stretches
The synchronization of hydraulic cylinder is stretched out and provides extra motive force, and then can realize further increasing climbing capacity.
In order to prevent the weight tray 76 in the normal headwork of non-high inclination-angle tunnelling contacted with roadway floor into
And influence excavation operation, fitted with roadway floor leakiness when weight tray 76 fits support with roadway floor, as this hair
Bright further improvement project, described auxiliary climbing apparatus 7 also include balance hydraulic cylinder 75, and balance hydraulic cylinder 75 is arranged on leads
To the top of piston shoes 74, the one end of balance hydraulic cylinder 75 and process auxiliary drive frame assembly 73 are articulated and connected, the other end and guide slip shoe 74
It is articulated and connected；Can realize that control weight tray 76 is in horizontality or and tunnel by controlling the flexible of balance hydraulic cylinder 75
The parallel state of base plate.
In order that weight tray 76 is more securely supported in roadway floor, scheme, institute as a further improvement on the present invention
Swivel pin and tie-beam 71 that the support body front end of the process auxiliary drive frame assembly 73 stated is set along the longitudinal direction by axial direction
Rear end is articulated and connected, and the mode being articulated and connected can make process auxiliary drive frame assembly 73 and weight tray 76 follow the ground of roadway floor
Gesture carries out adaptability rotation, and then weight tray 76 can be made more securely to be supported in roadway floor.
Driven to increase auxiliary on the premise of auxiliary climbing apparatus 7 and the less installing space of rear lower of frame 1 are ensured
The installing space of moving frame assembly 73, guide slip shoe 74 and weight tray 76, and then the more thick and heavy weight tray 76 of size can be realized,
So as to further realizing more firm skidproof effect, scheme as a further improvement on the present invention, described tie-beam 71 is Z-shaped
Shape structure.
In order to realize more preferable skidproof effect, scheme as a further improvement on the present invention, on described weight tray 76
