Abstract
The invention discloses a hydraulic feed device of a drilling machine controlled by utilizing a four-position four-way valve. The hydraulic feed device comprises an upper chuck, a lower chuck, a hydraulic pump, an oil tank, a flow valve and the four-position four-way valve, wherein the inlet end of the four-position four-way valve is connected with the flow valve and the hydraulic pump respectively by pipelines; the hydraulic pump is connected with the oil tank by a pipeline; and the outlet end of the four-position four-way valve is connected with the upper chuck and the lower chuck respectively by pipelines. The hydraulic feed device has the characteristics that the structural design is reasonable, the maloperation is prevented, the structure is simple, and the construction efficiency is improved.
Description
Technical field
The present invention relates to a kind of hydraulic feed device of drilling machine, be used in the highwall-drilling machine with four-way valve control.
Background technology
In highwall-drilling machine, connect Hydraulic Power Transmission System and drilling rod with oild chuck at present, upper and lower scroll chuck control will be controlled as easy as rolling off a log generation faulty operation, complicated operation with 2 hydraulic directio control valves.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic feed device of drilling machine with four-way valve control, the present invention has reasonable in design, prevents faulty operation, the characteristics of simple structure, raising efficiency of construction.
For reaching above-mentioned purpose, the present invention adopts following technical scheme:
A kind of hydraulic feed device of drilling machine with four-way valve control, comprise upper chuck, lower chuck, hydraulic pump, fuel tank, stream valve and four-way valve, wherein the four-way valve entrance point is connected with hydraulic pump with the stream valve respectively by pipeline, and hydraulic pump links to each other by pipeline with fuel tank; The four-way valve port of export is connected with upper chuck, lower chuck respectively by pipeline.
The invention has the beneficial effects as follows: the present invention has reasonable in design by the improvement to rig upper chuck hydraulic system to rig, can prevent faulty operation, and simple structure is easy to use, the characteristics that efficiency of construction is high.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of hydraulic feed device of drilling machine with four-way valve control, comprise upper chuck 5, lower chuck 6, hydraulic pump 3, fuel tank 1, stream valve 2 and four-way valve 4, wherein four-way valve 4 entrance points are connected with hydraulic pump 3 with stream valve 2 respectively by pipeline, and hydraulic pump 3 and fuel tank 1 link to each other by pipeline; Four-way valve 4 ports of export are connected with upper chuck 5, lower chuck 6 respectively by pipeline.
Hydraulic feed device is installed in the support, and upper chuck 5 is normally closed types, unclamps when hydraulic oil is arranged, lower chuck 6 is open in usual, clamps when hydraulic oil is arranged and leans on, when hydraulic valve 4 is in a position, upper chuck 5 gets Chinese pine and opens, and lower chuck 6 loses Chinese pines and opens, and drilling rod loosens up and down, quit work, when hydraulic valve 4 was in the b position, upper chuck 5 lost oil and clamps, and lower chuck 6 loses Chinese pine and opens, drilling rod connects with machine driven system, creep into, when hydraulic valve 4 was in the c position, upper chuck 5 lost oil and clamps, lower chuck 6 gets oily clamping, drilling rod clamps up and down, is used to change bar, when hydraulic valve 4 is in the d position, upper chuck 5 gets Chinese pine and opens, lower chuck 6 gets oily clamping, and the drilling rod counter-rotating is used for down bar, by using a hydraulic valve to realize four runnings of rig, realize creeping into, unload bar, fall bar and stopping.The drilling rig hydraulic system that can be used for various operations.
