Abstract
The utility model relates to a pneumatic crawler rock drilling machine compression mechanism which comprises a main valve; the utility model is characterized in that the gas outlet pipeline of the main valve is divided into two lines, one line is sent to an impact rock drilling mechanism through an oil mist device and the other line is sent to an operating mechanism; the output pipeline of the main valve is connected with a main pressure meter, and the output pipeline of a pressure adjusting valve is connected with a pressure meter. The device can adapt to the wind source of the high, medium and low pressure, which makes the pneumatic crawler rock drilling machine normally work under the high, medium and low pressure. The pressure display of each part is intuitional, the adjustment is convenient and accurate, and each mechanism has the good lubricating effect.
Description
Technical field:
The utility model relates to a kind of gas pressure mechanism of pneumatic type crawler belt rock drilling machine, particularly can adapt to the gas pressure mechanism of high, normal, basic three kinds of blast.
Background technology:
The CM351 type crawler type pneumatic drilling rig that has a kind of " Xuanhua-Ingersoll-rand " to produce that in engineering construction, is widely used at present, its gas pressure mechanism is that Compressed Gas is after main valve (ball valve) is adjusted, after adding mist of oil, oil sprayer is divided into two-way again, one the tunnel directly delivers to impact drilling mechanism, and operating mechanism is delivered in another road behind pressure regulator valve, safety valve.This gas pressure mechanism can not adapt to the low pressure wind regime because the restriction of safety valve can only adapt to middle and high pressure wind regime, promptly can not give operating mechanism with enough air quantity when low pressure, and operating mechanism is failure to actuate.There is not pressure-display device owing to this mechanism again, thus the wind pressure of complete machine and the required wind pressure of each mechanism except that impact drilling can't be shown, so adjust difficulty.Simultaneously, because this mechanism has only an oil sprayer, the mechanism that each need be lubricated obtains best lubrication effect.
The content of invention:
The purpose of this utility model is will provide a kind of can adapt to high, medium and low three kinds of blast, and intuitive display, and high lubricating effect is adjusted and is easy to pressure mechanism.
The technical solution of the utility model is: this gas pressure mechanism comprises main valve, and its characteristics are that the outlet pipe of main valve 1 is divided into two-way output, and one the tunnel delivers to impact drilling mechanism behind an oil sprayer 3; Deliver to operating mechanism behind another Lu Jingyi valve 7, pressure regulator valve 4, the oil sprayer 6; One gross pressure table 2 is housed on the output pipe of main valve 1; One pressure meter 5 is housed on the output pipe of pressure regulator valve 4.
The utlity model has following advantage and effect: one, under the control of main valve and valve and pressure regulator valve, adjusting, finish the adjustable controlled of system pressure, realized at high, medium and low blast (during 0.4Mpa～2.4Mpa), but equal operate as normal, this is that any similar rig all can't be accomplished at present.Two, owing to adorned two pressure meters, very directly perceived when making the operator adjust each several part pressure, air quantity, the while also provides necessary condition for adjusting each several part pressure.Three, owing to be that two paths have been equipped with independently oil sprayer respectively, so fully lubricated, mechanical efficiency is improved.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
As Fig. 1,, deliver to total valve 1 through pipeline from the Compressed Gas that air compressor is sent here, be connected to a gross pressure table 2 on the output pipe of total valve 1, the outlet pipe of total valve 1 is divided into two-way, and one the tunnel delivers to impact drilling mechanism behind an oil sprayer 3 apply oils, for the usefulness of impact drilling.Operating mechanism is delivered in another road behind valve 7, pressure regulator valve 4, oil sprayer 6 apply oils, for the usefulness of walking and other actions.By adjusting total valve 1, valve 2 and pressure regulator valve 6, observe gross pressure table 2 and pressure meter 5 simultaneously, the wind regime that just can adapt to different pressures (high, medium and low), make pneumatic type crawler belt rock drilling machine that this device controls can be under high, medium and low blast all can operate as normal, thereby expanded the blast accommodation of pneumatic type crawler belt rock drilling machine greatly.
