Description

Technical Field

[0001] The present invention relates to the technical field of road deicing, and more specifically to an adaptive deicing brush plate hydraulic control system. In addition, the present invention also relates to an ice remover including the adaptive deicing brush plate hydraulic control system. Background Art

[0002] There is long-term snowfall in the northern part of my country in winter, and the roads are seriously covered with snow and ice. Traffic and residents' outdoor activities are greatly restricted. How to clear ice and snow in a timely and effective manner is crucial. Common ice and snow roads are divided into thin ice roads and repeatedly compacted snow roads. Among them, the cleaning of thin ice roads is particularly difficult. There are three main methods for removing thin ice at home and abroad, namely the hot melt method, the freezing inhibition pavement improvement method and the mechanical removal method. However, the existing methods for deicing thin ice roads have the problems of poor deicing effect, low operating efficiency and great damage to the road surface. In particular, the damage to the road surface seriously damages the service life of the road surface. In order to solve this problem, researchers have invented a deicing brush disc with the function of protecting the road surface.

[0003] The existing patent (Announcement No.: CN205475046U) proposes a road surface adaptive semi-rigid deicing brush, which consists of a deicing brush head, a brush head floating mechanism, a circular brush plate and a brush plate fixing seat. When the working road surface is uneven, the deicing brush head can swing up and down through the brush head floating mechanism to achieve the effect of road surface adaptiveness, which can effectively improve the removal efficiency and reduce the mechanical damage to the road surface and the deicing brush head caused by the uneven road surface during snow and ice removal.

[0004] The existing patent (Announcement No.: CN218813456U) proposes a curved wire deicing brush device, including a square brush plate, a fastening fixture, a wire rope, an anti-loosening sleeve, a driving shaft, a driving ring column, a movable lever, and a fastening block. The curved wire deicing brush device uses pure plastic bristles and curved steel wire as an ice brushing structure, which can not only easily remove ice and snow on the road surface, but also improve the deicing ability and reduce the damage of the brush head to the ground by increasing the pure plastic bristles and adjusting the flexibility of the wire rope according to the hardness of the ice on the road surface.

[0005] The existing patent (Announcement No.: CN218813457U) proposes a new de-icing brush device, including a circular brush plate, a steel wire rope, an anti-loosening sleeve, a fixing clamp, a brush head fixing support, a threaded rotating rod, a positioning buckle plate, and a positioning lock strip. The new de-icing brush device can improve the de-icing ability and reduce the damage of the brush head to the ground by adding pure plastic bristles and adjusting the flexibility of the steel wire rope according to the hardness of the ice on the road surface while clearing ice and snow on the road surface. The steel wire rope can be replaced individually or as a whole according to the wear and tear of the steel wire rope, thereby improving the replacement efficiency of the ice brush and the de-icing effect.

[0006] The deicing brush disc invented so far can protect the road surface when performing deicing operations. However, it is still impossible to adjust the pressure of the deicing brush disc on the road surface in real time according to the changes in the height of the road surface, so that the deicing brush disc and the road surface always maintain a constant and appropriate force. If the pressure between the deicing brush disc and the road surface is too large, the deicing brush disc will still cause a certain degree of damage to the road surface, weakening its ability to protect the road surface. If the pressure between the deicing brush disc and the road surface is too small, the deicing brush disc cannot perform deicing operations well due to insufficient force, which will reduce its operating efficiency.

[0007] In summary, how to provide a control system applied to the deicing brush disc to ensure that the deicing brush disc always applies the most suitable pressure to the road surface is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0008] In view of this, the purpose of the present invention is to provide an adaptive de-icing brush disc hydraulic control system, in which the sensed pressure between the de-icing brush disc and the road surface is used as an input signal. The controller controls the control valve group according to the input signal, and then adjusts the vertical lifting of the de-icing brush disc. The lifting of the de-icing brush disc further adjusts the pressure of the de-icing brush disc on the road surface, so that no matter how the road conditions change, the de-icing brush disc always adaptively adjusts the pressure acting on the road surface according to the changes in the road conditions, thereby realizing intelligent adaptive flexible de-icing.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The core of the present invention is to provide an adaptive de-icing brush disc hydraulic control system. The controller controls the lifting and lowering action of the de-icing brush disc by sensing the pressure between the de-icing brush disc and the road surface. The lifting and lowering action is used to reduce or increase the pressure of the de-icing brush disc on the road surface, so that the pressure between the de-icing brush head and the road surface is always at the most appropriate value.

[0040] Another core of the present invention is to provide a deicer including the above-mentioned adaptive deicing brush disc hydraulic control system.

[0041] Please refer to Figure 1-Figure 2 .

[0042] This specific embodiment discloses an adaptive de-icing brush disc hydraulic control system, comprising: an oil tank 10; a first oil cylinder 8, a telescopic end of which is connected to the de-icing brush disc; a second oil cylinder 9, a telescopic end of which is connected to the de-icing brush disc; a control valve assembly, connected to the first oil cylinder 8 and the second oil cylinder 9 to control the lifting and lowering of the first oil cylinder 8 and the second oil cylinder 9; a power assembly, connected to the control valve assembly, for extracting the hydraulic oil in the oil tank 10 to the first oil cylinder 8 and the second oil cylinder 9; the rodless chamber of the first oil cylinder 8 and the rodless chamber of the second oil cylinder 9 are both connected to the oil tank 10.

[0043] In the process of using the adaptive deicing brush plate hydraulic control system provided in this specific embodiment, the pressure oil in the oil tank 10 is pumped out to the control valve assembly through the power assembly, and the lifting and lowering of the first oil cylinder 8 and the second oil cylinder 9 can be controlled by controlling each valve body in the control valve assembly, thereby realizing the lifting and lowering control of the deicing brush head. The lifting and lowering control of the deicing brush plate includes: controlling the telescopic end of the first oil cylinder 8 and the telescopic end of the second oil cylinder 9 to extend, retract, and remain stationary at the same time.

[0044] Compared with the prior art, the adaptive deicing brush disc hydraulic control system provided in this specific embodiment controls the control valve assembly through the hydraulic sensor input signal, can realize adaptive lifting and lowering of the brush head structure, and can achieve flexible deicing during the control process.

[0045] In a specific embodiment, if Figure 1 As shown, the control valve assembly includes: an oil supply solenoid valve 4, whose oil inlet is connected to the power assembly, and whose oil outlet is connected to the oil inlet of the first check valve 6; an oil unloading solenoid valve 5, whose oil inlet is connected to the oil outlet of the second check valve 7, and whose oil outlet is connected to the oil tank 10;

[0046] The control valve assembly includes a first one-way valve 6 and a second one-way valve 7, the oil inlet of the first one-way valve 6 is connected to the oil supply solenoid valve 4, and the oil outlet of the first one-way valve 6 is connected to the rodless chamber of the first cylinder 8 and the second cylinder 9; the oil inlet of the second one-way valve 7 is connected to the rodless chamber of the first cylinder 8 and the second cylinder 9, and the oil outlet of the second one-way valve 7 is connected to the oil unloading solenoid valve 5.

[0047] The adaptive de-icing brush head lifting hydraulic control system also includes a relief valve 3, one end of which is connected to the oil tank 10, and the other end is connected to the oil outlet of the power component; during use, the relief valve 3 can play a role in system safety protection to avoid the impact of excessive oil pressure on the system.

[0048] During specific use, the power component includes an engine 1 and a variable pump 2 driven by the engine 1, and the variable pump 2 is connected to the oil tank 10 and the control valve assembly; in the initial state of the engine 1 starting, the engine 1 starts to drive the variable pump 2 to rotate, and the oil outlet of the variable pump 2 maintains a constant pressure and outputs a minimum flow, that is, it automatically adjusts to the flow required for the position system leakage.

[0049] When the de-icing brush disc needs to be lowered, the oil unloading solenoid valve 5 can be energized and the oil supply solenoid valve 4 can be de-energized. At this time, the oil inlet and oil outlet of the oil unloading solenoid valve 5 are connected, and the oil inlet and oil outlet of the oil supply solenoid valve 4 are not connected. The rodless chambers of the first oil cylinder 8 and the second oil cylinder 9 are connected to the oil tank 10; under the action of the self-weight of the de-icing brush head structure, the telescopic ends of the first oil cylinder 8 and the second oil cylinder 9 retract and descend at the same time, thereby lowering the de-icing brush disc.

[0050] When the de-icing brush disc needs to rise, the oil supply solenoid valve 4 can be energized and the oil unloading solenoid valve 5 can be de-energized. At this time, the oil inlet and oil outlet of the oil supply solenoid valve 4 are connected, and the oil inlet and oil outlet of the oil unloading solenoid valve 5 are not connected. The rodless chambers of the first oil cylinder 8 and the second oil cylinder 9 are connected to the power assembly; under the action of the power assembly, the telescopic ends of the first oil cylinder 8 and the second oil cylinder 9 extend and rise at the same time, thereby raising the de-icing brush disc.

[0051] When the de-icing brush disc needs to remain stationary, the oil supply solenoid valve 4 and the oil unloading solenoid valve 5 can be controlled to lose power. At this time, the oil inlet and the oil outlet of the oil supply solenoid valve 4 are not connected, and the oil inlet and the oil outlet of the oil unloading solenoid valve 5 are also not connected. The rodless cavity oil circuit of the first oil cylinder 8 and the second oil cylinder 9 is closed; the telescopic ends of the first oil cylinder 8 and the second oil cylinder 9 remain stationary, thereby keeping the de-icing brush disc structure stationary.

[0052] In a specific embodiment, the adaptive de-icing brush plate hydraulic control system includes a hydraulic sensor 11 and a controller 12. The hydraulic sensor 11 is used to monitor the hydraulic values ​​of the rodless chambers of the first cylinder 8 and the second cylinder 9. The hydraulic sensor 11 and the control valve assembly are both connected to the controller 12.

[0053] Since the real-time pressure of the de-icing brush disc on the road surface is equivalent to the real-time supporting force of the road surface on the de-icing brush disc, the hydraulic pressure in the rodless cavity of the first cylinder 8 and the second cylinder 9 is used to support the de-icing brush disc, and the gravity of the de-icing brush disc is constant, the pressure of the de-icing brush disc on the road surface corresponds to the hydraulic pressure value of the rodless cavity of the first cylinder 8 and the second cylinder 9 in real time.

[0054] The hydraulic sensor 11 monitors the hydraulic values ​​of the rodless chambers of the first cylinder 8 and the second cylinder 9 and sends the monitored pressure signals to the controller 12 , which is equivalent to monitoring the pressure between the de-icing brush plate and the road surface and sending the monitored pressure signals to the controller 12 .

[0055] The controller 12 receives the hydraulic signal transmitted by the hydraulic sensor 11, and compares it with the threshold value set by the controller 12, and controls the action of the control valve group according to the comparison result; if the hydraulic value sensed by the hydraulic sensor 11 is equal to the threshold value set by the controller 12, the pressure between the de-icing brush disc and the road surface is the most suitable pressure at this time; if the hydraulic value sensed by the hydraulic sensor 11 is lower than the threshold value set by the controller 12, the pressure between the de-icing brush disc and the road surface is slightly large, which is easy to damage the road surface; if the hydraulic value sensed by the hydraulic sensor 11 is higher than the threshold value set by the controller 12, the pressure between the de-icing brush disc and the road surface is slightly small, and the de-icing efficiency of the de-icing brush disc is low.

[0056] When the hydraulic value is equal to the threshold value set by the controller 12, the controller 12 controls the oil supply solenoid valve 4 and the oil unloading solenoid valve 5 to lose power. At this time, the oil inlet and the oil outlet of the oil supply solenoid valve 4 and the oil unloading solenoid valve 5 are not conductive; the hydraulic oil in the rodless cavity of the first cylinder 8 and the second cylinder 9 is sealed in the pipeline, so that the telescopic ends of the first cylinder 8 and the second cylinder 9 remain stationary, the deicing brush plate also remains stationary, and the pressure of the deicing brush plate on the road surface remains unchanged.

[0057] When the hydraulic value is lower than the threshold value set by the controller 12, the controller 12 controls the oil supply solenoid valve 4 to be energized and the oil unloading solenoid valve 5 to be de-energized. At this time, the oil inlet and oil outlet of the oil supply solenoid valve 4 are connected, and the oil inlet and oil outlet of the oil unloading solenoid valve 5 are not connected; the hydraulic oil pumped out by the variable pump 2 enters the rodless cavity of the first cylinder 8 and the second cylinder 9 through the oil supply solenoid valve 4 and the first one-way valve 6, so that the telescopic ends of the first cylinder 8 and the second cylinder 9 are extended, the deicing brush disc rises, and the deicing brush disc reduces the pressure on the road surface; as the pressure of the deicing brush disc on the road surface decreases, the hydraulic value of the rodless cavity of the first cylinder 8 and the second cylinder 9 will gradually increase to the threshold value set by the controller 12.

[0058] When the hydraulic value is higher than the threshold value set by the controller 12, the controller 12 controls the oil unloading solenoid valve 5 to be energized and the oil supply solenoid valve 4 to be de-energized. At this time, the oil inlet and oil outlet of the oil unloading solenoid valve 5 are connected, and the oil inlet and oil outlet of the oil supply solenoid valve 4 are not connected; the hydraulic oil in the rodless chamber of the first cylinder 8 and the second cylinder 9 enters the oil tank 10 through the second one-way valve 7 and the oil unloading solenoid valve 5, so that the telescopic ends of the first cylinder 8 and the second cylinder 9 are retracted, the deicing brush disc descends, and the deicing brush disc increases the pressure on the road surface; as the pressure of the deicing brush disc on the road surface increases, the hydraulic value of the rodless chamber of the first cylinder 8 and the second cylinder 9 will gradually decrease to the threshold value set by the controller 12.

[0059] In addition to the above-mentioned adaptive de-icing brush disc hydraulic control system, the present invention also provides a de-icing machine including the adaptive de-icing brush disc hydraulic control system disclosed in the above-mentioned embodiment. For the structures of other parts of the de-icing machine, please refer to the prior art and will not be described in detail herein.
