Abstract
The utility model relates to a large power closed system which is used for boring tool rotating driving in geophysical prospecting drills, comprising an enclosed pump 3, a filter 4, a hydraulic reservoir 6, etc. The hydraulic reservoir 6 is communicated with a hydraulic line of the system, and a plunger piston motor 1 is connected with the enclosed pump 3. A hydraulic pressure gage 2, a filter 4 and a pushing and pulling flexible axle 5 are communicated through the hydraulic line. The defects, such as small transmitted power, low efficiency, large heating, complicated control and too many peripheral lines of the hydraulic system and the variable displacement hydraulic system are solved. So the utility model has the advantages of large power, high efficiency, small heating, simple control and few connecting lines.
Description
Affiliated field
The utility model relates to a kind of equipment that the drilling tool rotation drives that is used in the physical prospecting rig, specifically, be high-power closed system.
Prior art
What existing hydraulically powered physical prospecting drilling rig hydraulic system used is the fixed dilivery hydraulic system of metering pump+selector valve+fixed displacement motor, or the open type variable delivery hydraulic system of variable displacement pump+selector valve+fixed displacement motor, they are mainly by the unit head motor, three position four-way directional control valve, hydralic pressure gauge, variable displacement pump (or metering pump), radiator, fuel tank assembly is formed, metering pump or variable displacement pump are by sucking hydraulic oil in the fuel tank, the compression back is transported to the oil hydraulic motor that drives the rig rotation by manual three position four-way directional control valve, selector valve is manually controlled the rotating speed of oil hydraulic motor and is turned to, system pressure is by being controlled by the relief valve that is integrated in the selector valve, hydralic pressure gauge display system force value, radiator are used for the heat that emanation system work produces.Hydraulic system uses power to be generally less than 60kW, and system is lower because of efficient, uses big capacity fuel tank and heat transmission gas mostly.
Technology contents
The purpose of this utility model is effectively to overcome that fixed dilivery hydraulic system power is little, at the bottom of the efficient, many disadvantages such as heating is big, control is complicated, the peripheral hardware pipeline is many, provide that a kind of power is big, efficient is high, heating is little, control is simple, connecting line is few.
The utility model is achieved in that and comprises piston motor 1, hydralic pressure gauge 2, enclosed pump 3, filter 4, push-and-pull flexible axle 5, hydraulic oil container 6, hydraulic oil container 6 is communicated with the hydraulic line of system, piston motor 1 is connected with enclosed pump 3, and hydralic pressure gauge 2, filter 4, push-and-pull flexible axle 5 are communicated with respectively by hydraulic line.
The utility model also adopts following technological scheme:
Push-and-pull flexible axle 5 and enclosed pump 3 directly are communicated with by hydraulic line.
The built-in control pump of enclosed pump 3, slippage pump.
The more fuel tap that piston motor 1 is built-in.
Advantage of the present utility model is: many disadvantages such as effectively solve fixed dilivery hydraulic system and open type variable delivery hydraulic system transmitted power is little, efficient is low, heating is big, control is complicated, the peripheral hardware pipeline is many, the enclosed variable delivery hydraulic system that we are big with power, efficient is high, heating is little, control is simple, connecting line is few (quiet liquid transmission) is applied in the high-power drilling rig hydraulic system of WTZ-70M.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in the figure, the built-in control pump of enclosed pump 3 sucks the hydraulic oil pressure back of contracting and provides power for the internal control of enclosed pump 3 from fuel tank 6; The high pressure oil that enclosed pump 3 produces directly drives 3 rotations of high-voltage high-speed piston motor, and the inlet port of enclosed pump 3 is directly arrived in oil return, forms closed cycle; Oil sump tank 6 cooling let out internal system recycle oil in proportion by piston motor 1 built-in more fuel tap, and the built-in slippage pump of enclosed pump 3 sucks in fuel tank 6 that hydraulic oil pressure contracts after external high pressure filter 4 adds to the closed system loop; Push-and-pull flexible axle 5 is realized control to enclosed pump swash plate by the control to the reversing slide valve of enclosed pump 3, thus the displacement size of control pump and direction, the control that finally reaches motor rotary speed and turn to; The pressure in closed system loop is shown by pressure gauge 2.
