Description
Technical field
The utility model relates to the hydraulic disc brake control system technical field on winch.
Background technology
Along with from the late 20th century disc brake device since petroleum drilling winch is brought into use, hydraulic disc type brake device instead of traditional band brake, becomes current topmost brake pattern.At present, hydraulic disc brake is divided into hydraulic control and automatically controlled two profiles formula according to mode.Hydraulic control hydraulic disc brake be manually hydraulic valve to regulate brake pressure.Electric-controlled hydraulic disk type brake is by solenoid-operated proportional valve regulation brake pressure.AC frequency conversion winch improves gradually due to the reliability of resistance braking, and hydraulic disc brake only uses as auxiliary braking with when shutting down.At present, conventional hydraulic disc brake is furnished with and often opens pincers and normally closed pincers two kinds of braking clamps, and adopt during work brake and often drive pincers, adopt normally closed pincers during parking, during emergency brake, two kinds of braking clamps all participate in braking.AC frequency conversion winch is owing to adopting resistance braking as the most frequently used braking pattern, and conventional its configuration of hydraulic disc type brake device seems more than needed.
Publication number is 201224674, and publication date is that the Chinese patent literature on April 22nd, 2009 discloses a kind of electric control hydraulic disc type brake device, is applied to the winch brake of oil-well rig or service machine.Form primarily of brake actuator, Hydraulic Station and electric operation control unit three part.Feature is: its hydraulic control system is made up of hydraulic reservoir, two constant pressure variable displacement pumps, five check valves, by pass valve, eight pressure sensors, four energy storages, two solenoid directional control valves, hydraulic control one-way valve, two electromagnetic proportional valves, two pilot operated directional control valves, temperature controller, heat exchanger, fluid level controller, two working clamp fluid cylinders and safety tongs fluid cylinders.Effect is: can realize power-off self-actuating brake, system failure self-shield, can realize coordinated signals with Winch control system, can meet the electrical control requirement of AC frequency variated rig and the automated drilling rig developed.Realize brake control exactly in addition, operant response is sensitiveer.Avoid that winch motor is overheated because winch brakes suddenly to be burnt out.
But with the hydraulic disc type brake device that above-mentioned patent documentation is representative, its structure is comparatively complicated, manufacturing cost is higher and be not easy to later maintenance.
Summary of the invention
The utility model is intended to for the defect existing for above-mentioned prior art and deficiency, provides a kind of complete normally closed pincers hydraulic disc brake control system, and the utility model hydraulic circuit is simple, and productive costs is lower and maintain easily.
The utility model realizes by adopting following technical proposals:
A kind of complete normally closed pincers hydraulic disc brake control system, it is characterized in that: comprise energy storage, Hydraulic Station, parking brake clamps, work braking clamp, work brake ratio adjusting valve, emergency stop valve, parking brake valve and driller station, its annexation is: energy storage is connected with emergency stop valve with Hydraulic Station, Hydraulic Station is through emergency stop valve, work brake ratio adjusting valve is connected with work braking clamp, and emergency stop valve, work brake ratio adjusting valve is controlled platform with department respectively and is connected, Hydraulic Station is through emergency stop valve, parking brake valve clamps with parking brake and is connected, and parking brake valve is controlled platform be connected with department.
The control handle of emergency stop button, control work brake ratio adjusting valve and parking brake valve is provided with in described department control platform.
Described parking brake pincers and work braking clamp are normally closed pincers.
Compared with prior art, the beneficial effect that reaches of the utility model is as follows:
1, braking clamp all adopts normally closed pincers, and lock torque is larger, and when the failure conditions such as power-off occur all braking clamp auto-actions, safety is higher.
2, all adopt normally closed pincers, hydraulic circuit is simpler, optimizes the structure of coiling Hydraulic Station of stopping, reduces manufacturing cost, more convenient maintenance.
3, decrease the kind that on-the-spot accessory is got the raw materials ready, can productive costs be reduced.
4, the design of operating mode remains emergency brake button and brake handle, without the need to changing driller's operating habit.
Accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation.
Mark in figure:
1-energy storage; 2-Hydraulic Station; 3-parking brake clamps; 4-works braking clamp; 5-work brake ratio adjusting valve; 6-emergency stop valve; 7-parking brake valve; 8-driller station.
Detailed description of the invention
With reference to Figure of description, preferred forms of the present utility model is, it discloses a kind of complete normally closed pincers hydraulic disc brake control system, comprise energy storage 1, Hydraulic Station 2, parking brake pincers 3, work braking clamp 4, work brake ratio adjusting valve 5, emergency stop valve 6, parking brake valve 7 and driller station 8, its annexation is: energy storage 1 is connected with emergency stop valve 6 with Hydraulic Station 2, Hydraulic Station 2 is through emergency stop valve 6, work brake ratio adjusting valve 5 is connected with work braking clamp 4, and emergency stop valve 6, work brake ratio adjusting valve 5 is controlled platform with department respectively and is connected, Hydraulic Station 2 is through emergency stop valve 6, parking brake valve 7 and parking brake clamp 3 and are connected, and parking brake valve 7 is controlled platform be connected with department.The control handle of emergency stop button, control work brake ratio adjusting valve 5 and parking brake valve 7 is provided with in described department control platform.Described parking brake pincers 3 and work braking clamp 4 are normally closed pincers.
Its principle of work is as follows:
1, service braking
By the control handle of operation electronics brake lever, regulate normally closed pincers to the positive pressure of brake disc, thus the brake torque providing size adjustable for main frame, meet the requirement of different operating modes such as sending brill, make a trip.
2, emergency braking
In case of emergency, press emergency stop button, whole normally closed pincers participate in braking, realize emergency brake.
3, overtravel protection
Overtravel protection system and the chain control of pulleying signal, when hook lifting heavy rises to certain position, due to operator's error or other reason; should service braking and do not implement braking time; pulleying valve or anti-collision valve can send signal, and system will implement emergency braking automatically, avoid touching overhead traveling crane accident.
4, braking during standstill
When rig does not work or driller will leave operator's station, pull braking during standstill change-over swith, two normally closed pincers oil cylinder release brakes, in case hook landing.
