Technical field
The utility model relates to the rotary drilling rig technical field, especially a kind of hoist motor multifunction integrated valve group.
Background technique
Elevator is important in a rotary drilling rig structure.Winding of rotary drilling rig generally is furnished with hoist motor and hoist brake.For realizing the several functions of elevator, hoist motor can be furnished with the many kinds of liquid pressure valve.Rotary drilling rig is transferred at drilling rod and is required hoist brake to open in the process, elevator can under driving, motor be rotated, when creeping into, require hoist motor to be in quick condition, and when elevator stops, require to drive the motor of elevator by the hydrovalve braking and to the motor repairing.
Conventional apparatus is to take at former motor 22 former reductor braking device 24 to be installed as shown in Figure 2, and then external former shuttle valve 26, solenoid valve 1 reach unsteady purpose; Braking Fill valve group 21 realizes the braking of former motor 22 and to former motor 22 repairings; 2 25 work of reductor braking device 24 rear electromagnetic valves are opened in solenoid valve one 27 work floats elevator 23.
The braking Fill valve group own vol of original state of the art is huge, and wants external two solenoid valves and shuttle valve, and peripheral pipeline connects complicated and occupies very large space.
The model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of hoist motor multifunction integrated valve group.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hoist motor multifunction integrated valve group, elevator connects reductor braking device and hoist motor, hoist motor is connected with two stop valves and the throttle orifice two of connecting, two actuator ports of hoist motor are connected to respectively relief valve one and relief valve two, the repairing road of relief valve one is connected with the repairing road of relief valve two, and relief valve one another road is communicated to filler opening B mouth through brake balancing valve one, brake balancing valve two; Relief valve two another roads are communicated to filler opening A mouth through shuttle valve, sequence valve, decompression relief valve successively; Sequence valve is connected to the decompression relief valve; Relief valve one tunnel is connected to port M3 through throttle orifice one, and another road is connected to two solenoid directional control valves, and in addition two one of hydraulic fluid ports of two solenoid directional control valves lead to external pilot hydraulic fluid port P1, and another leads to the reductor braking device.
The beneficial effects of the utility model are, the multiple valve that the utility model will separate is integrated together, and realize the several functions of hoist motor, and level of integration is high, and volume is little, and processing is worthy to be popularized easily.

Among the figure, 1-1, relief valve one, 1-2, relief valve two, 2, two solenoid directional control valves, 3-1, brake balancing valve one, 3-1, brake balancing valve one, 3-2, brake balancing valve two, 4, shuttle valve, 5, sequence valve, 6, decompression relief valve, 7, throttle orifice one, 8, two stop valves, 9, throttle orifice two, 10, hoist motor, 11, elevator, 12, the reductor braking device, 21, braking Fill valve group, 22, former motor, 23, former elevator, 24, former reductor braking device, 25, solenoid valve one, 26, former shuttle valve, 27, solenoid valve two.
Embodiment
Hydraulic schematic diagram of the present utility model such as Fig. 1, a kind of hoist motor multifunction integrated valve group, elevator 11 connects reductor braking device 12 and hoist motor 10, hoist motor 10 is connected with two stop valves 8 and the throttle orifice 29 of connecting, two actuator ports of hoist motor 10 are connected to respectively relief valve one 1-1 and relief valve two 1-2, the repairing road of relief valve one 1-1 is connected with the repairing road of relief valve two 1-2, and another road of relief valve one 1-1 is communicated to filler opening B mouth through brake balancing valve one 3-1, brake balancing valve two 3-2; Another road of relief valve two 1-2 is communicated to filler opening A mouth through shuttle valve 4, sequence valve 5, decompression relief valve 6 successively; Sequence valve 5 is connected to decompression relief valve 6; Relief valve 6 one tunnel is connected to port M3 through throttle orifice 1, and in addition two one of hydraulic fluid ports that another road is connected to 2, two solenoid directional control valves 2 of two solenoid directional control valves lead to external pilot hydraulic fluid port P1, and another leads to reductor braking device 12.
As shown in accompanying drawing 1,3,4: relief valve one 1-1, relief valve two 1-2 are the relief valve with the repairing function, and can play restriction motor maximum service pressure and inhale when empty at motor is the effect of motor repairing; Brake balancing valve one 3-1, brake balancing valve two 3-2 play the effect of braking when motor stops.Shuttle valve 4 can compare the maximum pressure of motor A/B in-line, and the hydraulic oil of A/B mouth passed to sequence valve 5, when A/B oil circuit maximum pressure reached the setting value of sequence valve 5, sequence valve 5 was opened, hydraulic oil passes to decompression relief valve 6, and hydraulic oil is opened hoist brake through decompression relief valve 6.Because the maximum pressure that hoist brake can bear is far below the pressure of motor A/B oil circuit, so need to carry to hoist brake through the decompression of decompression relief valve 6, be similarly the maximum pressure of restriction hoist brake inside, decompression relief valve 6 is also with relief function.Two solenoid directional control valves 2, two stop valves 8, throttle orifice 29 synergy are played when rig creeps into and made elevator be in quick condition: two solenoid directional control valve 2 its functions are when motor A/B oil circuit does not have hydraulic oil to enter, two solenoid directional control valve 2 actions, to from the external pilot oil input hoist brake of P1 mouth, hoist brake be opened; Two stop valves 8 can separate the cut-off of the hydraulic oil in motor A, the B oil circuit when motor works, when elevator requires to float, and two stop valve 8 energization actions, with motor A, B oil circuit UNICOM, motor begins to rotate under the weight effect; Throttle orifice 29 can not only limit the maximum speed of motor, and the speed that motor is floated is steady.Being provided with path in the middle of relief valve one 1-1 and relief valve two 1-2 connects to motor repairing mouth S.Described multiple valve combination realizes floating, braking of elevator and is the motor repairing.
The utility model relates to hoist motor multifunction integrated valve group, be integrated with two stop valves, throttle orifice, relief valve, brake balancing valve, shuttle valve, sequence valve, decompression relief valve, two solenoid directional control valves, original multiple valve that separates is integrated together, realize the several functions of hoist motor, compact structure, level of integration is high, and volume is little, processing is worthy to be popularized easily.
