Description
Technical field
The utility model relates to the side unloading rock loader that the occasions such as a kind of colliery, non-coal mine and traffic tunnel field use, and especially relates to a kind of novel side unloading rock loader adopting Hydraulic guide control.
Background technology
In current colliery, the side dump dirt loader that the occasion such as non-coal mine and traffic tunnel uses, the control form of reversing control valve is all direct acting type, its control mode is mostly adopt traditional lever control (Direct Action Type manual manipulation mode), namely banked direction control valves there is an easy lever control mechanism, pull the spool work of banked direction control valves by pulling lever handle during operation, but because this leverage is subject to the restriction of banked direction control valves structure and locus, lever is smaller, namely pull the power of spool all larger during operation, cause the labour intensity of operating personnel very high, easily tired in the course of work, thus operating efficiency is lower.
Utility model content
For the deficiency existing for the side unloading rock loader that the occasions such as above-mentioned colliery, non-coal mine and traffic tunnel field use, the utility model provides a kind of novel side dump dirt loader adopting hydraulic pilot formula control system, this pilot-operated type Work Reliability of Hydraulic System is high, simple to operation and free and relaxed, significantly reduce the labour intensity of operating personnel, energy-saving effect is obvious, and easy accessibility during maintenance.
Find through market survey widely, user, in the urgent need to reducing operating physical force, improves the labour intensity of operating personnel, to improve operating efficiency.
The technical scheme that the technical problems to be solved in the utility model is taked is: described Hydraulic guide control new
Type side unloading rock loader comprises motor, operating cylinder, left running motor, right running motor, variable pump, pioneer pump, multiple directional control valve group, pilot-actuated valve, operating cylinder is connected with multiple directional control valve group, left running motor is connected with multiple directional control valve group respectively with right running motor, multiple directional control valve group is connected with radiator, radiator is connected with return filter, multiple directional control valve group is connected with variable pump, variable pump is connected with motor with pioneer pump, multiple directional control valve group is connected with guide's fuel feeding assembly by guide's oil circuit, pilot-actuated valve is by guide's oil circuit and cable drum motors, radiator is connected with radiator gear motor, variable pump is connected with hydraulic oil container.
The utility model technological innovation main points are:
1, side unloading rock loader main hydraulic system adopts variable pump, multi-channel proportional reversal valve and performs hydraulic part (oil cylinder, motor etc.) composition.
2, Hydraulic guide control system is primarily of the composition such as pioneer pump (being often gear pump), guide's fluid pressure line, guide's fuel feeding assembly, guide's strainer and pilot-actuated valve (pilot handle), and handle is pulled free and relaxed, simple to operation.Pilot-operated type organic liquor type pilot and electric liquid type pilot (being mainly used in non-coal mine).
3, during work, pull pilot-actuated valve (pilot handle) as required and control guide's fluid, then guide's fluid flows to the hydraulic control end of corresponding multiple directional control valve by pilot line, and promote the spool action of multiple directional control valve, thus make high-pressure work fluid flow to the corresponding working hole controlling to perform hydraulic part (oil cylinder, motor etc.) by hydraulic oil pipeline, namely carry out corresponding action (as flexible in oil cylinder, revolution etc.).
The utility model adopts the novel side dump dirt loader of hydraulic pilot formula control system, this pilot-operated type Work Reliability of Hydraulic System is high, simple to operation and free and relaxed, significantly reduces the labour intensity of operating personnel, energy-saving effect is obvious, and easy accessibility during maintenance.

Detailed description of the invention
In FIG, the novel side unloading rock loader of Hydraulic guide control comprises motor 1, operating cylinder 5, left running motor 6, right running motor 7, variable pump 2, pioneer pump 3, multiple directional control valve group 4, pilot-actuated valve 9, except above-mentioned part, other part of dirt loader is identical with existing dirt loader.Three operating cylinders are all connected with multiple directional control valve group, left running motor is connected with multiple directional control valve group respectively with right running motor, multiple directional control valve group is connected with radiator 14, radiator is connected with return filter 13, multiple directional control valve group is connected with variable pump, variable pump is connected with motor respectively with pioneer pump, multiple directional control valve group is represented by guide's oil circuit 16(doublet) and guide's fuel feeding assembly 10, pilot-actuated valve 9 is connected with cable drum motor 8 by guide's oil circuit 16, radiator 14 is connected with radiator gear motor 12, variable pump 2 is connected with hydraulic oil container 15, better, guide's fuel feeding assembly 10 is connected with guide's strainer 11.
The whole course of work illustrates: electric motor starting rotates, the variable pump of coaxial assembling and pioneer pump is driven to rotate, and by fuel sucking pipe inspiration hydraulic oil from hydraulic oil container, hydraulic oil is by becoming hydraulic oil after pump, multiple directional control valve is flow to by hydraulic oil pipeline, if spool is not opened, then hydraulic oil directly flows back to hydraulic oil container from the oil return opening of banked direction control valves, if the spool of multiple directional control valve is opened by guide's fluid, then hydraulic oil passes through the follow-up afterflow of control of multiple directional control valve to hydraulic actuator (as oil cylinder or motor etc.), and after completing corresponding action, hydraulic oil (now oil pressure has become very low) flows to radiator by fluid pressure line, and hydraulic oil container is flowed back to after heat radiation, namely a working cycles is completed.
