Abstract
The utility model discloses an oil-way for a drilling machine, which belongs to the technical field of coal mine machineries, comprising a fuel tank, a filter, a motor, a gear oil pump, an overflow valve, a multipath reversing valve, a compression gauge, a compression gauge, quick-change joint, a hydraulic motor, a throttle valve, a feed-in oil cylinder, an oil return compression gauge and a cooler. The multipath reversing valve is formed by two sets of three-position and six-way reversing valve and a set of four-position and six-way reversing valve in parallel connection. The four-position and six-way reversing valve is formed by adding an one-position and six-way floating oil-way based on a three-position and six-way reversing valve. The four-position and six-way reversing valve is connected to an oil cylinder, controlling a drilling rod to retreat, stop, forward and float. The oil-way for a drilling machine is advantageous in that a feeding mechanism can reduce wearing of screw threads of a drilling rod when the drilling rod is dismounted; structure is simplified and labor is saved; underground work efficiency is improved; safety and usage performance of the integral device are improved compared with those of the prior art.
Description
Technical field
The utility model belongs to the coal mine machinery technical field, relates to a kind of rig and uses oil circuit.
Background technique
ZDY650 type hydraulic drill rig is that power head type drill rig is used in a kind of colliery, adopts three groups three the six logical multiple directional control valves that compose in parallel always, and its Left-wing Federation is connected with oil hydraulic motor, is used for controlling the rotation of drilling tool; Middle one group links to each other with throttle valve, is used to control the feed speed of drilling tool; The right couplet links to each other with oil cylinder, is used to control drilling rod and retreats, stops and advancing.When multiple directional control valve during at meta, when rig is in halted state, carry out the drilling rod loading and unloading, this moment, right three six-way transfer valve meta functions that join were the O type; The characteristics of O type be into, return opening all seals; Even there is the external force effect can not make operation mechanism move or rotate; This just makes and must utilize during drilling rod parts such as hard spring on the unit head, six square shafts to reduce the wearing and tearing of mounting or dismounting drilling rod to drill rod thread in loading and unloading; Cause inefficiency, labor intensity is big.
Summary of the invention
To the problems referred to above, when the purpose of the utility model is to provide a kind of dismounting drilling rod, can effectively reduce wearing and tearing to drill rod thread, laborsaving, the rig that efficient is high is used oil circuit.
The utility model adopts such technological scheme to realize; A kind of rig oil circuit; Comprise fuel tank, filter I, motor, gear oil pump, relief valve, multiple directional control valve, pressure gauge, quick release coupling, oil hydraulic motor, throttle valve, feed oil cylinder, return pressure table, cooler and filter II, it is characterized in that: multiple directional control valve is formed in parallel by two groups of three six-way transfer valves and one group of four six-way transfer valve; Wherein four six-way transfer valves link to each other with oil cylinder, and these four six-way transfer valves are on original three six-way transfer valve bases, to have increased by one the six logical oil circuit that floats.
Said filter I and filter II are fine filter.
The right side of multiple directional control valve joins four six-way transfer valves and is connected with oil cylinder, is used to control drilling rod and retreats, stops, advancing and float.When these four six-way transfer valves are in the 4th, during the oil circuit position of promptly floating, carry out the drilling rod loading and unloading.
Because adopted the oil circuit that floats, when the rig down drilling rod, oil cylinder can move with the external force effect, make feed mechanism when dismounting drilling rod, reduce the wearing and tearing to drill rod thread, and can save parts such as hard spring on the unit head, six square shafts.
The utility model is through increasing one the six logical oil circuit that floats on three original six-way valves; Make feed mechanism when dismounting drilling rod, reduce wearing and tearing to drill rod thread; Both simplified the structure; Saved the labour again, improved underground work efficient, all improved a lot simultaneously at similar than before rigs in aspect such as the Security of equipment complete machine and usability.

Among the figure, 1-fuel tank, 2-filter I, 3-motor, 4-gear oil pump; The 5-relief valve, 6-multiple directional control valve, 7-pressure gauge, 8-quick release coupling, 9-oil hydraulic motor; The 10-throttle valve, 11-feeds oil cylinder, 12-return pressure table, 13-cooler; 14-filter II, three six-way transfer valves of 6-1-, three six-way transfer valves of 6-2-, four six-way transfer valves of 6-3-.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified, but the utility model not only is confined to this.
Embodiment; A kind of rig oil circuit; Comprise fuel tank 1, filter I 2, motor 3, gear oil pump 4, relief valve 5, multiple directional control valve 6, pressure gauge 7, quick release coupling 8, oil hydraulic motor 9, throttle valve 10, feed oil cylinder 11, return pressure table 12; Cooler 13 and filter II 14, its middle filtrator I 2 is fine filter with filter II 14; Multiple directional control valve 6 is formed in parallel by two groups of three six-way transfer valves and one group of four six-way transfer valve, and the Left-wing Federation of multiple directional control valve 6 is three six-way transfer valve 6-1, is connected with oil hydraulic motor 9, is used for controlling the rotation of drilling tool; Middle one group of three six-way transfer valve 6-2 link to each other with throttle valve 10, are used to control the feed speed of drilling tool; Four six-way transfer valve 6-3 of right couplet link to each other with oil cylinder 11, and these four six-way transfer valve 6-3 are the six logical oil circuits that float that on original three six-way transfer valve bases, increased a Y type, are used to control drilling rod and retreat, stop, advancing and float.When four six-way transfer valve 6-3 are in the 4th, during the oil circuit position of promptly floating, carry out the drilling rod loading and unloading.
Because adopted the oil circuit that floats, when the rig down drilling rod, oil cylinder 11 can move with the external force effect, make feed mechanism when dismounting drilling rod, reduce the wearing and tearing to drill rod thread, and can save parts such as hard spring on the unit head, six square shafts.
