Fig. 3 is a circuit schematic of the hydraulic control system 30 of the barring support structure 20 shown in fig. 2. As shown in fig. 3, the barring support structure 20 further comprises a hydraulic control system 30 electrically connected with the first and second

telescopic assemblies

In some embodiments, the driving motor 33 is electrically connected to the controller 31 and is drivingly connected to the hydraulic pump 32, and the hydraulic pump 32 is connected to the first and

second telescoping assemblies

23 and 24. The controller 31 controls the driving motor 33 to deliver power to the hydraulic pump 32 according to the control command, so that the hydraulic pump 32 provides hydraulic pressure to the first and second

telescopic assemblies

23 and 24. The first and second

telescopic assemblies

23 and 24 perform reciprocating motion when receiving hydraulic pressure output by the hydraulic pump 32. The first telescopic assembly 23 and the second telescopic assembly 24 can share the same oil pressure pipeline or different oil pressure pipelines to be connected with the hydraulic pump 32, so that the arrangement can be flexible. And are not limited in this application. Compared with the related art, the automatic control is easy to realize through electric control, and the labor intensity is reduced.

In some embodiments, relief valve 34 is coupled between hydraulic pump 32 and first telescoping assembly 23 and is electrically coupled to controller 31. The controller 31 controls the on/off of the relief valve 34 according to the control command, and controls the on/off of the hydraulic pump 32 and the first expansion assembly 23. The relief valve 34 is used to control the opening and closing of the hydraulic pressure created by the hydraulic pump 32 to maintain a constant hydraulic pressure in the hydraulic control system 30 and ensure that a constant hydraulic pressure is provided to the first telescopic assembly 23.

In some embodiments, the controller 31 controls the communication of the relief valve 34 according to the control command, so as to establish a hydraulic system in the hydraulic control system 30, and the hydraulic pump 32 is communicated with the first telescopic assembly 23. In some embodiments, controller 31 controls relief valve 34 to be disconnected based on the control command, such that there is no hydraulic system within hydraulic control system 30, and hydraulic pump 32 is disconnected from first retraction assembly 23. The overflow valve 34 is arranged to control the on-off between the hydraulic pump 32 and the first telescopic assembly 23, so that the safety protection effect is achieved when a hydraulic system is built in the hydraulic control system 30. When the pressure in the hydraulic control system 30 exceeds a specified value, the overflow valve 34 is pushed open to discharge a part of gas in the hydraulic control system 30 to the atmosphere, so that the pressure in the hydraulic control system 30 does not exceed the specified value, accidents of the hydraulic control system 30 caused by overhigh pressure are avoided, and the safety is higher. And when debugging before the barring supporting structure 20 leaves the factory, the pressure value of the overflow valve 34 in the hydraulic control system 30 is preset, and the pressure value is constantly output, so that the risk of unfixed pretightening force in the use process is reduced. Moreover, the overflow valve 34 can be adjusted steplessly, and the system pressure can be kept constant after setting, so that the system is stable and reliable.

The controller 31 controls the first solenoid valve 35 according to the control command, and controls the hydraulic pressure between the first telescopic assembly 23 and the hydraulic pump 32, thereby controlling the moving state of the first telescopic assembly 23 in the first direction X. The first solenoid valve 35 may be a solenoid directional valve. May be a solenoid valve switch that controls the fluid between the hydraulic pump 32 and the first telescoping assembly 23.

In some embodiments, the controller 31 controls the first solenoid valve 35 to conduct according to the control command to conduct the hydraulic pump 32 and the first telescopic assembly 23, and controls the moving state of the first telescopic assembly 23. In this process, the moving state of the first telescopic assembly 23 can be controlled independently, and is not limited in this application. In some embodiments, the controller 31 controls the relief valve 34 to be opened according to the control command to disconnect the control hydraulic pump 32 from the first telescopic assembly 23, and the moving state of the first telescopic assembly 23 cannot be controlled.

For example, the controller 31 controls the first solenoid valve 35 to be conducted according to the control command, and the hydraulic pump 32 provides hydraulic pressure to the first telescopic member 23, at which time the first telescopic part 232 can be telescopically moved. The first electromagnetic valve 35 is arranged to control the on-off between the hydraulic pump 32 and the first telescopic assembly 23, the moving state of the first telescopic assembly 23 is controlled, automatic control can be achieved, and labor force can be reduced. And through electric control, can guarantee to have invariable hydraulic pressure force to reduce the risk that the pretightning force is unset in the use, the security is higher.

When the controller 31 controls the driving motor 33 to start, the hydraulic pump 32 is driven to rotate, and at this time, the hydraulic pump 32 outputs hydraulic oil. At this point, the relief valve 34 is energized, hydraulic control system 30 establishes hydraulic pressure, and the pressure gauge indicates the pressure value. The first solenoid valve 35 is powered, and the controller 31 can control the first telescopic parts 232 of the first telescopic assemblies 23 on two opposite sides to extend so as to support the side plates 21 on two sides. Similarly, when the first electromagnetic valve 35 is powered, the controller 31 can control the second telescopic parts 242 of the second telescopic assemblies 24 located at two opposite sides to drive the side plate 21 along the second direction Y. By so doing, the brake disc 133 is rotated, thereby rotating the hub 131.

The controller 31 controls the second solenoid valve 36 to adjust the throttle valve 37 according to the control command, thereby adjusting the moving speed of the first telescopic assembly 23 in the first direction X. The second solenoid valve 36 and the throttle valve 37 are connected in parallel to the first solenoid valve 35. The second solenoid valve 36 may be a solenoid directional valve. The first solenoid valve 35 and the second solenoid valve 36 are switched to be used.

The throttle valve 37 is a one-way throttle valve. For example, when the flow rate of the hydraulic line is controlled to be small by the throttle valve 37, the moving speed of the first expansion/contraction part 232 is decreased. When the flow rate of the hydraulic line controlled by the throttle valve 37 is large, the moving speed of the first expansion/contraction part 232 is increased. By providing the second solenoid valve 36 and the throttle valve 37, the moving speed of the first telescopic part 232 can be flexibly controlled, and flexibility is enhanced.

It should be noted that, for the moving state and the moving speed of the second telescopic assembly 24, the overflow valve 34, the first electromagnetic valve 35, the second electromagnetic valve 36 and the throttle valve 37 may also be used for controlling, and the specific implementation process and the implementation principle thereof may refer to the above, which are not described herein again.

Since the left and right support within disc 133 are of the same principle, clockwise and counter-clockwise rotation of disc 133 is similar. In the embodiment shown in fig. 2, only the clockwise rotation of the left support and brake disc 133 is illustrated. The first telescopic assembly 23 includes an installation process, a working process, and a disassembly and assembly process. Wherein the content of the first and second substances,

the installation process of the first telescopic assembly 23 specifically includes: the second base portion 241 is first connected to the fixed bracket 22 and connected to a corresponding hydraulic hose, which is connected to the hydraulic pump 32. The controller 31 controls the start driving motor 33 and the relief valve 34 to be electrified to establish hydraulic pressure. The first solenoid valve 35 is energized, and the first telescopic part 232 extends out. When the front end of the first telescopic part 232 exceeds the mounting hole of the side plate 21, the first electromagnetic valve 35 is de-energized, the second electromagnetic valve 36 is energized, the throttle valve 37 is adjusted, the moving speed of the first telescopic part 232 is reduced, and the front end of the first telescopic part 232 is aligned with the mounting hole of the side plate 21 and is mounted and connected. After completion, the back-adjustment throttle valve 37 returns to the initial maximum position.

The operation of the first telescopic assembly 23 specifically comprises: the controller 31 controls the start driving motor 33 and the overflow valve 34 to be electrified to establish hydraulic pressure, the first electromagnetic valve 35 is electrified, the first telescopic part 232 continuously extends out to support the side plate 21, and the inner side of the first telescopic part is tightly attached to the inner side of the brake disc 133. At this point, the second retraction assembly 24 is activated and lifted to a position where the latch assembly 28 extends and is inserted into the first and second alignment holes 27, 134. At the moment, the side plate 21 does not need to be supported, the overflow valve 34 loses power, the system pressure is unloaded, and the power is saved. When the first electromagnetic valve 35 is de-energized, the first telescopic assembly 23 is in the neutral unloading state, the first telescopic part 232 of the first telescopic assembly 23 is in the floating state, the brake disc 133 drives the blade 132 to rotate clockwise, and the first telescopic part 232 also changes along with the side plate 21 in the ascending process. Before the side plate 21 begins to descend, the overflow valve 34 and the first electromagnetic valve 35 are powered, the first telescopic part 232 extends to support the side plate 21, the bolt assembly 28 extends and is separated from the side plate 21 and the brake disc 133, and the second telescopic part 242 begins to retract. In the operation process, the hole distance between the front end of the first telescopic part 232 and the mounting hole of the side plate 21 is reduced and then increased, when the hole distance is reduced, the first telescopic part 232 retracts, and oil of the first telescopic part 232 is extruded to overflow through the overflow valve 34. When the hole distance is increased, the first expansion part 232 extends out, the oil supplied by the hydraulic pump is supplemented with the required oil, and the oil overflowing from the overflow valve 34 is reduced. In this process, the relief valve 34 can control the hydraulic pressure of the hydraulic pump 32 and maintain the supporting force to the side plate 21 constant, reliably and stably.

The disassembling and assembling process of the first telescopic assembly 23 specifically includes: the controller 31 controls the start driving motor 33, the relief valve 34 and the first solenoid valve 35 to be energized, and controls the latch assembly 28 mounted on the side plate 21 and the brake disc 133 to be retracted. The two ends of the first electromagnetic valve 35 are simultaneously de-energized, the first telescopic assembly 23 is in neutral unloading, the first telescopic assembly 23 is in a floating state, the side plate 21 compresses the second telescopic assembly 24 by means of gravity, and the side plate 21 returns to the position where the side plate is initially jacked and extended. The connection of second retraction assembly 24 is now removed. The second electromagnetic valve 36 is electrified, the second telescopic part 242 retracts completely, the driving motor 33, the overflow valve 34 and the first electromagnetic valve 35 are all electrified, and a hydraulic rubber pipe and a connecting piece connected with the second telescopic part 242 are disassembled.

Therefore, the controller 31 controls the components to be circularly executed, so that automatic control can be realized, the labor intensity is reduced, and the operation and the adjustment are more convenient. In some embodiments, the Controller 31 may include any suitable Programmable Circuit or device, such as a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Controller (PLC), an APPlication SPecific Integrated Circuit (ASIC), and so on. The controller 31 may be implemented in a combination of hardware and software.

The specific structure and implementation process thereof can be seen from the above. The barring frock can realize automatic control by using the barring supporting structure 20, does not need manual operation, and is simple in operation and convenient to adjust.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
