Detailed description of the invention
Further illustrate the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, 2, a kind of horizontal drill for Railway Bed Slope high pressure jet grouting, the power section being formed by hydraulic power unit 19.By rotary fluid motor 12, floating power head 13, feed back the chain type that drags hydraulic motor 11, chain 8 and front sprocket wheel 17 and rear sprocket wheel 10 to form and feed Hui Tuo mechanism and the clamp unscrewing operating part that casing 16 and drilling rod clamp unscrewing mechanism, water tap 14 and drilling cramp plate 7 form that floats, wherein said drilling rod clamp unscrewing mechanism comprises that the unscrewing device being driven by front and back drill pipe clamp and the two-way cylinder of hydraulic oil cylinder driving respectively forms.In switch board 6, be provided with the operation part being formed by hydraulic control circuit and operating grip and display.Of the present utility model being characterized by: above-mentioned horizontal drill is provided with along roadbed side slope 1 and lays and fixing closed slide 3, the drilling cramp plate 7 of horizontal drill is provided with the support 5 making it as level, its bottom of support 5 with respect to the both sides of closed slide 3 be at least provided with respectively two with the respective track roller 4 engaging that rolls.
The bottom surface of described closed slide 3 one sides is provided with and makes its work plane is the bottom side 3-1 of level, and this bottom side fixes with the ironware 2 that is embedded in roadbed side slope.
As shown in Figure 1,3, the utility model is formed rotary fluid motor 12, is fed back the hydraulic control system of dragging hydraulic motor 11, rear drill pipe clamp oil cylinder 16-1, front drill pipe clamp oil cylinder 16-3 and unscrewing device two-way cylinder 16-2 by the variable pump of hydraulic power unit 19 and the hydraulic control circuit of operation part and operating grip.
Hydraulic control circuit in hydraulic control system is made up of the load sensing multi-way valve in Fig. 3 (6) and power level safety system; each load-sensitive valve is respectively equipped with pressure-compensated valve (8) and pressure limiting valve (7); power level safety system is made up of choke valve (12), sequence valve (11), overflow valve (10) and liquid proportional pilot valve (13), and its annexation is same as the prior art.As can be seen from Figure 3, rotary fluid motor 12 drags hydraulic motor 11, rear drill pipe clamp oil cylinder 16-1 and unscrewing device two-way cylinder 16-2, front drill pipe clamp oil cylinder 16-3 to be connected with hydraulic control circuit respective load sensitive valve respectively with feeding back.
Below sketch the operating principle of above-mentioned hydraulic control system: this hydraulic control system is by the opening degree of manipulation load sensing multi-way valve (6), make variable pump (9) export corresponding flow, thereby adjust the speed of service of executing agency, realize executing agency's stepless time adjustment by the opening degree of adjusting load sensing multi-way valve (6).In five execution units, rotary fluid motor 12 drags hydraulic motor 11 to move with feeding back simultaneously, because each load-sensitive valve is respectively equipped with pressure-compensated valve (8), make valve port pressure reduction only relevant with recuperation valve and irrelevant with load, can ensure each load-sensitive valve stability of flow, do not interfere with each other, reach the object of the multiple executing agencies of oil pump feed control action.In order to ensure to reduce heating overflow in the time that load reaches setting value, in each load-sensitive valve, be provided with pressure limiting valve (7), arrive after pressure pressure limiting valve and open signal feedback to variable pump restrictive pump pressure and flow, make few gauging greatly reduce heating loss by overflow valve.
The effect of power level safety system is the overpower phenomenon of avoiding horizontal drill simultaneously to occur in high pulling torque, high rotating speed, large pulling force and fast feed; when system pressure is during lower than 13Mpa; sequence valve (11) is in closed condition; the P mouth pressure of liquid proportional pilot valve (13) is load-sensitive valve control oil supply pressure 2Mpa; the outlet pressure of liquid proportional pilot valve (13) regulates between 0-2Mpa, the stepless time adjustment between 0-110RPM/Min of rotary fluid motor 12 rotating speeds.Once pressure higher than 13Mpa, sequence valve (11) is opened, it is 1Mpa that load-sensitive valve control oil sources regulates pressure liquid proportional pilot valve (13) P mouth pressure by overflow valve (10), the outlet pressure of liquid proportional pilot valve (13) regulates between 0-1Mpa, the stepless time adjustment between 0-70RPM/Min of rotary fluid motor rotating speed, thus limit power attenuation.In this voltage-regulating system, pass through to regulate choke valve (12) opening degree control pilot flow, proof load sensitive valve control oil supply pressure 2Mpa is (before choke valve, after load-sensitive valve reducing valve), because choke valve (12) inlet pressure is stable, its outlet pressure is set up by overflow valve, therefore throttling stability of flow (pressure reduction is certain), the stable of flow can ensure the stable of overflow valve set pressure, this has just ensured the stable of system.
