Description
Technical field
It is specifically a kind of to be opened suitable for ± 25 ° of high inclination-angle tunnels the present invention relates to a kind of climbing control method of development machine
The climbing control method for digging the high inclination-angle development machine of driving, belongs to development machine equipment technology field.
Background technique
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
It 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 many advantages, such as it is safe and efficient and high-quality at lane, it is especially outstanding
Road headers, it integrates the functions such as cutting, shipment, walking, operation, is mainly used for the underground of cutting arbitrary shape section
Rock, coal or alternate heading.
At inclination angle during biggish raise advance, the downslide that development machine can be generated by self weight, downslide is not only resulted in
The cutting efficiency decline of development machine can not even promote, and it is serious will cause safety accident, therefore the work that development machine is applicable
Make inclination angle generally within ± 16 °, tunnel inclination angle is super to be generallyd use hand-holing when going beyond the scope and blow out carry out excavation operation
Be big gun pick mode, big gun dig operation not only risk is very high but also drivage efficiency is lower, if getting working face be located at water body under,
Forbid big gun to dig when under building with " under three " getting working face under railway, tunnel digging angle can only be changed, not only increased
Add workload, and reduces the waste exploited length, in turn result in coal resources in tunnel.
High inclination-angle development machine in the prior art takes the torque for directly promoting driving crawler belt hydraulic motor more, increases crawler belt

The rear of the bottom end of frame (1), and telescopic supporting rod (61) relative to rack (1) fold expanded angle less than 90 °；The step
Support rod fold is first controlled before controlling hydraulic motor travel motor and auxiliary drive hydraulic motor (731) output power in rapid b at the same time
Hydraulic cylinder and the stretching of support rod telescopic hydraulic cylinder, which stretch out telescopic supporting rod (61) fold from the top of rack (1), makes rod end support plate
(62) top plane is firm to be supported on back, then controls hydraulic motor travel motor and auxiliary drive hydraulic motor simultaneously
(731) stretching of the support rod telescopic hydraulic cylinder of synchronously control telescopic supporting rod (61) provides additional promotion when output power
Power.
