It is dynamic, while as the constantly improve and country of State Grid's development are to environmentally friendly attention, increasing engineering truck operation is adopted
With driven by power, such as：Shotcreting jumbo, drill jumbo etc..The handy cable drum of safety is always to govern these vehicles to answer
Factor, and valve block that good cable drum is needed is controlled.
Utility model content
The purpose of this utility model is to provide a kind of cable drum valve block, in solving the problems, such as background technology.
The utility model is realized using following technical scheme：
A kind of cable drum valve block, including shuttle valve, back pressure check valve, check valve, overflow valve, choke valve, hydraulic motor, liquid
Pressure brake and oil circuit, the shuttle valve are connected to the two ends of oil circuit, and the shuttle valve two ends are connected with check valve, the check valve with
Back pressure check valve is in parallel, and the hydraulic motor is in parallel with choke valve, and the choke valve is in parallel with two overflow valves, the overflow valve
Joint of the two ends respectively with back pressure check valve and check valve be connected, liquid braking device, institute are provided with the hydraulic motor
State liquid braking device to be connected with shuttle valve, the outlet of the overflow valve and oil communication.
In the utility model, the shuttle valve, back pressure check valve, check valve, overflow valve, choke valve are arranged at valve block body
Outer wall.
Beneficial effect：The utility model simple structure, can effectively control hydraulic motor, so as to coordinate the work of cable drum
Make.The utility model can make cable drum effectively realize automatic management and automatic cycle function, make hydraulic motor formula coil of cable
Cylinder can be used in the application of synchronous folding and unfolding cable, while the service life of hydraulic motor can also be greatly improved.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model；
Fig. 2 is one outline drawing at visual angle of the utility model；
Fig. 3 is the outline drawing at another visual angle of the utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, a kind of structure principle chart of cable drum valve block, a kind of cable drum valve block, including shuttle valve 1, back pressure
Check valve 2, check valve 3, overflow valve 4, choke valve 5, hydraulic motor 6, liquid braking device 7 and oil circuit 8, the shuttle valve 1 are connected to
The two ends of oil circuit 8, the two ends of the shuttle valve 1 are connected with check valve 3, and the check valve 3 is in parallel with back pressure check valve 2, the hydraulic pressure
Motor 6 is in parallel with choke valve 5, and the choke valve 5 is in parallel with two overflow valves 4, the two ends of the overflow valve 4 respectively with back pressure list
Connected to the joint of valve 2 and check valve 3, be provided with liquid braking device 7 on the hydraulic motor 6, the liquid braking device 7 with
Shuttle valve 1 is connected, and the outlet of the overflow valve 4 is connected with oil circuit 8.
Referring to Fig. 2 and Fig. 3, a kind of one outline drawing at visual angle of cable drum valve block, a kind of cable drum valve block another
The outline drawing at visual angle, the shuttle valve 1, back pressure check valve 2, check valve 3, overflow valve 4, choke valve 5 are arranged at valve block body 9
Outer wall.
During using on cable drum, by adjusting two overflow valves 4, the input of hydraulic motor 6 can be changed and it is exported
Between pressure differential, so as to adjust around cable moment of torsion, when pressure is lacked, choke valve 5 can be adjusted, so as to adjust hydraulic motor manually
6, reel is remained able to cable laying is carried out manually, regulation shuttle valve 1 can start liquid braking device 7, and shuttle valve 1 can be in reel not
Pipe can open liquid braking device 7 when being and rotate clockwise or counterclockwise, check valve 3 and back pressure check valve 2 give liquid
Pressure motor 6 provides certain back pressure, makes always full of hydraulic oil in hydraulic motor 6, can quick response around cable, while being also prevented from
Certain obstruction power is provided when braking effect is lacked prevents reel from falling cable.
The utility model can make cable drum effectively realize automatic management and automatic cycle function, make hydraulic motor formula electricity
Cable reel can be used in the application of synchronous folding and unfolding cable, while the service life of hydraulic motor can also be greatly improved.
General principle of the present utility model and principal character and advantage of the present utility model, one's own profession has been shown and described above
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model, the utility model
Claimed scope is by appending claims and its equivalent thereof.
