A tray sweeping system 100 for a vehicle according to an embodiment of the present application is described below with reference to fig. 1 to 2.
The sweeping tray system 100 for a vehicle according to an embodiment of the first aspect of the present application includes: sweeping disc 10, link span, drive arrangement and controlling means.
The sweeping disk 10 is rotatably connected to a link frame, one end of which is connected to the vehicle body, and the other end of which is rotatably connected to the sweeping disk 10, whereby the sweeping disk 10 rotates relative to the link frame and also relative to the vehicle body. The sweeping disk 10 can swing back and forth relative to the connecting frame, that is, the sweeping disk 10 can swing forward relative to the connecting frame, and the sweeping disk 10 can also swing backward relative to the connecting frame, or the sweeping disk 10 can swing left relative to the connecting frame, and the sweeping disk 10 can also swing right relative to the connecting frame.
The driving device is installed on the connecting frame, the driving device can be fixedly connected with the connecting frame, the control device controls power output of the driving device, the driving device can be used for driving the sweeping disc 10 to rotate around the first axis, and the driving device can also be used for driving the sweeping disc to rotate around the second axis, namely the driving device can selectively drive the sweeping disc 10 to rotate around the first axis and can also selectively drive the sweeping disc 10 to rotate around the second axis, so that the sweeping disc 10 faces different directions, and the sweeping disc 10 is inclined left and right or front and back.
Wherein the angle between the first axis and the second axis is larger than 60 degrees, so that the sweeping disk 10 can swing towards two different directions. In some embodiments, as shown in fig. 1, an extending direction of the first axis may be perpendicular to an extending direction of the second axis, wherein the first axis may be disposed to extend in a front-rear direction and the second axis extends in a left-right direction.
Thus, when the sweeping disk 10 rotates around the first axis, the sweeping disk 10 swings towards the left or the right relative to the connecting frame, and the inclination angle of the sweeping disk 10 is further adjusted; when the sweeping disk 10 rotates around the second axis, the sweeping disk 10 swings forwards or backwards relative to the connecting frame, and the pitch angle of the sweeping disk 10 is adjusted.
Alternatively, the first axis may be provided to extend in the left-right direction, and the second axis may be provided to extend in the front-rear direction. Thus, when the sweeping disk 10 rotates about the first axis, the sweeping disk 10 swings forward or backward with respect to the link, and when the sweeping disk 10 rotates about the second axis, the sweeping disk 10 swings left or right with respect to the link.
The control device can comprise an operation key arranged in the cab, so that a driver can operate the control device in the cab, the orientation of the sweeping disc 10 can be flexibly adjusted by the driver according to the actual working environment and road conditions, and the sweeping disc 10 can adapt to more road conditions.
Therefore, a driver can operate the sweeping tray system 100 in the cab without moving the sweeping tray system outside the cab to manually adjust the sweeping tray 10, the use is convenient, the automation degree is high, the labor intensity of the driver is effectively reduced, and the sweeping tray system 100 is simple in structure and low in cost.
According to the sweeping disk system 100 for the vehicle of the embodiment of the application, the driving device drives the sweeping disk 10 to selectively rotate around the first axis or the second axis so as to automatically adjust the sweeping disk 10 to face different directions. Thus, on one hand, the driver can adjust the rotation direction of the sweeping disk 10 in real time according to the road condition, so that the vehicle can adapt to more road conditions. Meanwhile, the working efficiency of the vehicle is higher, the structure is simple, the cost is low, and the labor intensity of drivers is effectively reduced.
In some embodiments, as shown in fig. 2, the driving device comprises a hydraulic cylinder, a piston 311 is arranged in the hydraulic cylinder, the piston 311 divides the inner cavity of the hydraulic cylinder into a first cavity and a second cavity, and the piston 311 in the hydraulic cylinder can selectively move towards the first cavity or the second cavity. Namely, the connecting rod of the piston 311 can move towards the direction extending into the hydraulic cavity or the direction extending out of the hydraulic cavity, so that the connecting rod of the piston 311 extends out of the hydraulic cylinder to drive the sweeping disk 10 to rotate around the first axis or the second axis, and the angle adjustment of the sweeping disk 10 towards different directions is realized.
As shown in fig. 2, the left chamber in the hydraulic cylinder is a first chamber, and the right chamber in the hydraulic cylinder is a second chamber, so that the connecting rod of the piston 311 moves leftwards or rightwards, that is, by injecting hydraulic oil into the first chamber and the second chamber, respectively, so that the connecting rod of the piston 311 moves in two different directions.
When hydraulic oil is injected into the first cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing towards the left, and when hydraulic oil is injected into the second cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing towards the right; or when the hydraulic oil is injected into the first cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing forward, and when the hydraulic oil is injected into the second cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing backward.
Or when hydraulic oil is injected into the second cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing towards the left, and when hydraulic oil is injected into the first cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing towards the right; or when hydraulic oil is injected into the second cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing forwards, and when hydraulic oil is injected into the first cavity, the connecting rod of the piston 311 drives the sweeping disk 10 to swing backwards.
From this, through the selection with one in first chamber and the second chamber as the injection chamber, when another was as out the oil pocket, drive arrangement can drive sweep the dish 10 and rotate towards different directions for the driver can adjust the orientation of sweeping the dish 10 according to actual operational environment, road conditions are nimble, so that sweep the dish 10 and can adapt to more road conditions.
As shown in fig. 2, the control device includes a control valve for selectively communicating one of the first chamber and the second chamber with the oil outlet of the external hydraulic oil passage.
When the control device is used for controlling the hydraulic cylinder to drive the sweeping disc 10 to swing along the left-right direction, if the sweeping disc 10 needs to be driven to swing towards the left, the first cavity can be communicated with an oil outlet of an external hydraulic oil path through the control valve, hydraulic oil is injected into the first cavity, and therefore the connecting rod of the piston 311 drives the sweeping disc 10 to swing towards the left; if the sweeping disk 10 needs to be driven to swing rightwards, the second chamber can be communicated with an oil outlet of an external hydraulic oil circuit through the control valve, hydraulic oil is injected into the second chamber, and therefore the connecting rod of the piston 311 drives the sweeping disk 10 to swing rightwards.
When the control device is used for controlling the hydraulic cylinder to drive the sweeping disc 10 to swing along the front-back direction, if the sweeping disc 10 needs to be driven to swing forwards, hydraulic oil is injected into the first cavity when the first cavity is communicated with an oil outlet of an external hydraulic oil circuit through the control valve, so that the connecting rod of the piston 311 drives the sweeping disc 10 to swing forwards; if the sweeping disk 10 needs to be driven to swing backwards, hydraulic oil is injected into the second chamber when the second chamber is communicated with an oil outlet of an external hydraulic oil path through the control valve, so that the connecting rod of the piston 311 drives the sweeping disk 10 to swing backwards.
Therefore, the hydraulic cylinder is controlled by the control device to move to drive the sweeping disc 10 to rotate towards different directions, so that a driver can flexibly adjust the orientation of the sweeping disc 10 according to the actual working environment and road conditions, and the sweeping disc 10 can adapt to more road conditions.
As shown in fig. 2, the control valve is a three-position four-way valve, which includes a first port, a second port, and a third port.
The first valve port is communicated with the first cavity, the second valve port is communicated with the second cavity, and the third valve port is communicated with an oil outlet of an external hydraulic oil circuit; the third valve port is selectively communicated with one of the first valve port and the second valve port, the third valve port is an inlet of the control valve, and the first valve port and the second valve port are outlets of the control valve.
It can be understood that, when the valve core is located at the first end in the cavity of the control valve, the third port is communicated with the first port, external hydraulic oil enters the control valve from the third port, and then the external hydraulic oil flows into the first cavity communicated with the first port to push the connecting rod of the piston 311 to move towards the second cavity, so that the connecting rod of the piston 311 drives the sweep plate 10 to swing towards the left, and no hydraulic oil flows in the second port.
When the valve core is located at the second end in the cavity of the control valve, the third valve port is communicated with the second valve port, external hydraulic oil enters the control valve from the third valve port, and then the external hydraulic oil flows to the second cavity communicated with the second valve port to push the connecting rod of the piston 311 to move towards the first cavity, so that the connecting rod of the piston 311 drives the sweeping disk 10 to swing towards the right, and no hydraulic oil flows in the first valve port.
When the valve core is positioned in the middle of the cavity of the control valve, the third valve port is disconnected from the first valve port and the second valve port, at the moment, no hydraulic oil circulates in the first valve port and the second valve port, the hydraulic cylinder does not output driving force, the sweeping disc 10 is enabled to keep working in an original state, and the sweeping disc 10 keeps static along the left and right directions.
Or, when the valve core is located at the first end in the cavity of the control valve, the third valve port is communicated with the first valve port, external hydraulic oil enters the control valve from the third valve port, and then the external hydraulic oil flows into the first cavity communicated with the first valve port to push the connecting rod of the piston 311 to move towards the second cavity, so that the connecting rod of the piston 311 drives the sweeping disk 10 to swing forwards.
When the valve core is at the rightmost side, the third valve port is communicated with the second valve port, external hydraulic oil enters the control valve from the third valve port, and then the external hydraulic oil flows to the second cavity communicated with the second valve port to push the connecting rod of the piston 311 to move towards the first cavity, so that the connecting rod of the piston 311 drives the sweeping disk 10 to swing backwards.
When the valve core is in the middle, the third valve port is disconnected from the first valve port and the second valve port, so that the sweeping disc 10 keeps working in the original state, and the sweeping disc 10 keeps static in the front-back direction.
As shown in fig. 2, the sweeping tray system 100 for a vehicle further includes: and the bidirectional hydraulic lock 50 is arranged between the control valve and the hydraulic cylinder, so that the first valve port of the control valve is communicated with the first cavity in a unidirectional way, and the second valve port of the control valve is communicated with the second cavity in a unidirectional way.
Specifically, when the third valve port is communicated with the first valve port, external hydraulic oil flows from the first valve port to the first cavity through the bidirectional hydraulic lock 50, and the bidirectional hydraulic lock 50 enables the external hydraulic oil to be conducted in a single direction when the first valve port of the control valve flows to the first cavity, so that the hydraulic oil is effectively prevented from flowing back to the control valve; when the third valve port is communicated with the second valve port, external hydraulic oil flows from the second valve port to the second cavity through the bidirectional hydraulic lock 50, the bidirectional hydraulic lock 50 enables the external hydraulic oil to be conducted in a single direction when the external hydraulic oil flows to the second cavity through the second valve port of the control valve, and the hydraulic oil is effectively prevented from flowing back to the control valve.
Therefore, in the specific hydraulic control process, the hydraulic oil in the hydraulic loop flows in a single direction, the phenomenon of hydraulic oil backflow cannot occur, and the hydraulic control process is reasonably carried out, namely, the control operation of a driver can be timely responded.
From this, the one-way control structure of first chamber and second chamber all integrates in same two-way hydraulic pressure lock 50, need not set up each one-way conduction structure respectively alone, and can reach the same effect of preventing flowing backwards, reduces the cost that sets up one-way conduction structure alone, makes two-way hydraulic pressure lock 50's volume littleer, more convenient the arranging simultaneously, does benefit to the space that the overall structure that reduces sweeping tray system 100 occupied.
As shown in fig. 2, the two-way hydraulic lock 50 includes a first check valve 51 and a second check valve 52. The first check valve 51 is arranged between the first valve port and the first cavity so that the first valve port is communicated with the first cavity in a one-way, and hydraulic oil in the first cavity can be prevented from flowing back to the control valve; the second check valve 52 is disposed between the second port and the second chamber to make the second port conduct to the second chamber in one direction, so as to prevent the hydraulic oil in the second chamber from flowing back to the control valve.
It can be understood that when the third port is communicated with the first port, the external hydraulic oil flows from the first port to the first chamber through the first check valve 51, and the first check valve 51 makes the external hydraulic oil flow to the first chamber, so that the external hydraulic oil is conducted from the first port to the first chamber of the control valve in a single direction, and the hydraulic oil is effectively prevented from flowing back to the control valve.
When the third valve port is communicated with the second valve port, the external hydraulic oil flows from the second valve port to the second chamber through the second check valve 52, and the second check valve 52 enables the external hydraulic oil to be communicated in a one-way mode from the second valve port of the control valve to the second chamber in the process that the external hydraulic oil flows to the second chamber, so that the hydraulic oil is effectively prevented from flowing back to the control valve.
Therefore, through the two check valves of the bidirectional hydraulic lock 50, the second valve port and the first valve port are both in one-way communication, and the hydraulic oil is prevented from flowing backwards, so that the hydraulic cylinder can drive the sweeping disk 10 to stably rotate towards one direction.
As shown in fig. 2, the sweeping tray system 100 for a vehicle further includes: the oil filling oil path 60 is used for connecting the third valve port with an oil outlet of an external hydraulic oil path, and the oil outlet oil path 70 is used for selectively communicating with one of the first cavity and the second cavity of the hydraulic oil cylinder.
Specifically, when the third valve port is communicated with the first valve port, the oil injection oil path 60 is communicated with the third valve port, external hydraulic oil enters the control valve from the third valve port, the external hydraulic oil flows to the first cavity communicated with the first valve port to push the connecting rod of the piston 311 to move towards the second cavity, at the moment, the second cavity is communicated with the oil outlet oil path 70, so that the external hydraulic oil flows out of the hydraulic cylinder from the second cavity to enter the oil outlet oil path 70, and then the sweeping disc 10 is driven to swing towards the left in the process that the hydraulic oil pushes the piston 311 to move in the hydraulic cylinder.
When the third valve port is communicated with the second valve port, the oil injection oil path 60 is communicated with the third valve port, external hydraulic oil enters the control valve from the third valve port, the external hydraulic oil flows to the second cavity communicated with the second valve port to push the connecting rod of the piston 311 to move towards the first cavity, at the moment, the first cavity is communicated with the oil outlet oil path 70, so that the external hydraulic oil flows out of the hydraulic cylinder from the first cavity to enter the oil outlet oil path 70, and then the sweeping disc 10 is driven to swing towards the right in the process that the hydraulic oil pushes the piston 311 to move in the hydraulic cylinder.
Or when the third valve port is communicated with the first valve port, the oil injection oil path 60 is communicated with the third valve port, external hydraulic oil enters the control valve from the third valve port, the external hydraulic oil flows to the first cavity communicated with the first valve port to push the connecting rod of the piston 311 to move towards the second cavity, at the moment, the second cavity is communicated with the oil outlet oil path 70, so that the external hydraulic oil flows out of the hydraulic cylinder from the second cavity to enter the oil outlet oil path 70, and the sweeping disc 10 is driven to swing forwards in the process that the hydraulic oil pushes the piston 311 to move in the hydraulic cylinder.
When the third valve port is communicated with the second valve port, the oil injection oil path 60 is communicated with the third valve port, external hydraulic oil enters the control valve from the third valve port, the external hydraulic oil flows to the second cavity communicated with the second valve port to push the connecting rod of the piston 311 to move towards the first cavity, at the moment, the first cavity is communicated with the oil outlet oil path 70, so that the external hydraulic oil flows out of the hydraulic cylinder from the first cavity to enter the oil outlet oil path 70, and then the sweeping disc 10 is driven to swing backwards in the process that the hydraulic oil pushes the piston 311 to move in the hydraulic cylinder.
As shown in fig. 2, damping pipes 80 are disposed at the connection between the first chamber and the oil outlet passage 70 and at the connection between the second chamber and the oil outlet passage 70, so as to increase the resistance of the hydraulic oil in the oil outlet passage 70, so that the hydraulic oil is more stable in the hydraulic cylinder, and further, the position of the piston 311 in the hydraulic cylinder is more stable, so that the orientation of the swashplate 10 is kept stable when no hydraulic oil is injected into the hydraulic cylinder. Thus, the sweeping disk 10 does not rotate spontaneously during the sweeping process, and the reliability of the operation of the sweeping disk system 100 is improved.
As shown in fig. 1, the hydraulic cylinders include a first hydraulic cylinder 31a and a second hydraulic cylinder 31b, and the control valves include a first control valve 41a and a second control valve 41 b.
Wherein the first control valve 41a is used to selectively communicate one of the first chamber of the first hydraulic cylinder 31a and the second chamber of the first hydraulic cylinder 31a with the oil filling passage 60, and the other of the first chamber of the first hydraulic cylinder 31a and the second chamber of the first hydraulic cylinder 31a with the oil outlet passage 70, so that the connecting rod of the piston 311 of the first hydraulic cylinder 31a pushes the sweep plate 10 to rotate about the first axis, and the first axis extends in the front-rear direction, i.e., the connecting rod of the piston 311 of the first hydraulic cylinder 31a is used to push the sweep plate 10 to rotate in the left-right direction.
If the first control valve 41a connects the first chamber of the first hydraulic cylinder 31a with the oil filling path 60 and the second chamber of the first hydraulic cylinder 31a with the oil outlet path 70, at this time, the first chamber of the first hydraulic cylinder 31a is the oil filling chamber, the second chamber of the first hydraulic cylinder 31a is the oil outlet chamber, the piston 311 moves towards the direction close to the second chamber, and the connecting rod of the piston 311 of the first hydraulic cylinder 31a is used for pushing the sweeping disk 10 to rotate towards the left.
Or the first control valve 41a connects the second chamber of the first hydraulic cylinder 31a with the oil filling passage 60, and the first chamber of the first hydraulic cylinder 31a with the oil outlet passage 70, at this time, the second chamber of the first hydraulic cylinder 31a is an oil filling chamber, the first chamber of the first hydraulic cylinder 31a is an oil outlet chamber, the piston 311 moves towards the direction close to the first chamber, and the connecting rod of the piston 311 of the first hydraulic cylinder 31a is used for pushing the sweeping disk 10 to rotate towards the right.
Thus, the first control valve 41a can selectively control the hydraulic oil in the external oil passage to flow into the first chamber or the second chamber of the first hydraulic cylinder 31a to swing the sweep plate 10 leftward or rightward, so as to adjust the angle of the sweep plate 10 in the left-right direction.
The second control valve 41b is configured to selectively communicate one of the first chamber of the second hydraulic cylinder 31b and the second chamber of the second hydraulic cylinder 31b with the oil injection passage 60, and communicate the other of the first chamber of the second hydraulic cylinder 31b and the second chamber of the second hydraulic cylinder 31b with the oil discharge passage 70, so that the connecting rod of the piston 311 of the second hydraulic cylinder 31b pushes the sweep plate 10 to rotate around the second axis and the first axis extends in the left-right direction, that is, the connecting rod of the piston 311 of the first hydraulic cylinder 31a is configured to push the sweep plate 10 to rotate in the front-rear direction.
If the second control valve 41b connects the first chamber of the second hydraulic cylinder 31b with the oil filling path 60 and the second chamber of the second hydraulic cylinder 31b with the oil discharging path 70, at this time, the first chamber of the second hydraulic cylinder 31b is the oil filling chamber, the second chamber of the second hydraulic cylinder 31b is the oil discharging chamber, the piston 311 moves towards the direction close to the second chamber, and the connecting rod of the piston 311 of the second hydraulic cylinder 31b is used for pushing the sweeping disk 10 to rotate forwards.
