Fig. 2 is the liquid gas principle of signal conversion figure of the gas-liquid linked formula automatic brake arrangement of the utility model rotary drill.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the piston end of main Hoist braking cylinder 1 is inlet chamber 1a, inlet chamber 1a is connected with the control port of main lifting electromagnetic gas valve 2, and the piston opposite end of main Hoist braking cylinder 1 is provided with cylinder spring 1b, and main lifting electromagnetic gas valve 2 is three port two position electromagnetic gas valve.During normal work, main lifting electromagnetic gas valve 2 electromagnet obtains electric, and source of the gas 12 is to the inlet chamber 1a air feed of main Hoist braking cylinder 1, and the piston rod of main Hoist braking cylinder 1 is regained, cylinder spring 1b is compressed, and the main lifting band-type brake be connected with the piston end of main Hoist braking cylinder 1 declutches; When needing braking, main lifting electromagnetic gas valve 2 electromagnet dead electricity, main lifting electromagnetic gas valve 2 replaces, the inlet chamber 1a of main Hoist braking cylinder 1 loses source of the gas, cylinder spring 1b resets, the piston rod of main Hoist braking cylinder 1 stretches out, the main lifting brake sticking brake be connected with the piston end of main Hoist braking cylinder 1.In order to realize quick response when braking, pipeline between main Hoist braking cylinder 1 and main lifting electromagnetic gas valve 2 is provided with main Hoist braking quick exhaust valve 8, the inlet chamber 1a of main Hoist braking cylinder 1 makes gas in the jar discharge fast when losing source of the gas, and piston rod stretches out fast and realizes braking.
Main lifting electromagnetic gas valve 2 electromagnet electric and dead electricity, namely the commutation of main lifting electromagnetic gas valve 2 is controlled by the pressure relay 4 be arranged in the hydraulic circuit of HM Hydraulic Motor 3.As shown in Figure 2, HM Hydraulic Motor 3 be provided with pressurization oil inlet A and promote oil inlet B, pressurization oil inlet A is connected with the control port of HM Hydraulic Motor change-over valve 11 with lifting oil inlet B, HM Hydraulic Motor change-over valve 11 is five mouthfuls of three-position electromagnetic valves, HM Hydraulic Motor change-over valve 11 control presssure oil 10 enters HM Hydraulic Motor 3 through pressurization oil inlet A or lifting oil inlet B, realizes the pressurization descending pressurization of dolly or up lifting.HM Hydraulic Motor change-over valve 11 commutates to right position, and pressure oil enters HM Hydraulic Motor 3 through pressurization oil inlet A, drives HM Hydraulic Motor 3 clickwise, makes the descending pressurization of pressurization dolly; When HM Hydraulic Motor change-over valve 11 commutates to left position, pressure oil enters HM Hydraulic Motor 3, HM Hydraulic Motor 3 left-hand revolution through promoting oil inlet B, and pressurization dolly is upwards promoted.
Be provided with shuttle valve 5 between pressurization oil inlet A and lifting oil inlet B, pressure relay 4 is connected with shuttle valve 5.During normal work, shuttle valve 5 obtains the pressure signal coming from pressurization oil inlet A or promote oil inlet B, and pressure signal is converted to electric signal by pressure relay 4, and the electromagnet controlling main lifting electromagnetic gas valve 2 obtains electric, and main lifting band-type brake declutches.
Be arranged in parallel chain rupture with main Hoist braking cylinder 1 and protected cylinder 6, the piston rod of chain rupture protection cylinder 6 is connected with chain rupture band-type brake.The inlet chamber 6a of chain rupture protection cylinder 6 protect the control port of electromagnetic gas valve 7 to be connected with chain rupture, and chain rupture protects cylinder 6 inside to be provided with chain rupture cylinder spring 6b, and chain rupture is protected electromagnetic gas valve 7 to commutate and to be controlled by pressure relay 4.Chain rupture protection cylinder 6 and chain rupture are protected and the pipeline between electromagnetic gas valve 7 is provided with chain rupture is protected quick exhaust valve 9.The control principle of chain rupture protection cylinder 6 is identical with the control principle of main Hoist braking cylinder 1.
When HM Hydraulic Motor 3 attonity; namely HM Hydraulic Motor change-over valve 11 is in meta; or the pressurization oil inlet A of HM Hydraulic Motor 3 or promote oil inlet B oil circuit when there is booster; shuttle valve 5 does not have pressure signal; pressure relay 4 no signal exports; now main lifting electromagnetic gas valve 2 and chain rupture protection electromagnetic gas valve 7 all dead electricity, main lifting brake sticking brake, chain rupture brake sticking brake.The signal of pressure relay 4 derives from the hydraulic control circuit of HM Hydraulic Motor 3, can avoid the safety misadventure that braking failure occurs because electrical equipment is malfunctioning.
When scram button on push panel, main lifting electromagnetic gas valve 2 and chain rupture protection electromagnetic gas valve 7 all dead electricity, main lifting brake sticking brake; chain rupture brake sticking brake; pressurization dolly can rest on optional position, when can ensure rotary drill operation, and the safe operation of pressurization dolly up-and-down movement.
