As shown in fig. 1 to 4, the utility model discloses a cleaning system, this cleaning system includes: arm support mechanism 10, cleaning mechanism 20 and control mechanism. The boom mechanism 10 is disposed on the main body of the sweeping vehicle, e.g., at the side and front end of the main body of the sweeping vehicle; the sweeping mechanism 20 is connected to the boom mechanism 10 under the control of a control mechanism, and the control mechanism enables the sweeping mechanism 20 and the boom mechanism 10 to form a rigid connection and a floating connection in a two-week mode.

Specifically, as shown in fig. 1 to 3, the boom mechanism 10 includes a frame body 11, two adjusting cylinders, and a guide plate 13. The two adjusting cylinders 12 are used for changing the spatial attitude of the frame body 11, and thus can adjust the horizontal attitude of the cleaning mechanism 20, specifically, the spatial angular attitude of the cleaning disk 21 with respect to a flat road surface in the cleaning mechanism 20 mentioned later.

The cleaning mechanism 20 includes a mounting plate 23, a motor 22, and a sweeping disk 21, the mounting plate 23 includes a vertical plate 231 and a horizontal plate 232 which are integrally formed, and the sweeping disk 21 includes a disk body 211 and a broom brush 212 formed on the disk body 211 for cleaning a road surface. The sweeping disk 21 is arranged below the horizontal plate 232, the motor 22 is fixed above the horizontal plate 232, and an output shaft of the motor is connected to the disk body 211 after penetrating through the horizontal plate 232 for driving the sweeping disk 21 to rotate so as to enable the sweeping disk 21 to carry out sweeping operation.

As shown in fig. 4 in conjunction with fig. 1 to 3, the control mechanism includes: the hydraulic system comprises a hydraulic cylinder 31, a first valve 32, a second valve 33, a third valve 34, a controller 35, an oil replenishing valve, a first triggering module 361 and a second triggering module 362.

The hydraulic cylinder 31 includes a cylinder 311, a first piston 312, a second piston 313, a piston rod 318, a spring 314, a coil spring pad 315, a first joint 3114, and a second joint 3115. The cylinder 311 is vertically fixed on the guide plate 13 of the arm support mechanism 10 and is located at a position above the guide plate 13. The upper end of the cylinder body 311 is sealed by an upper end cover 316, the lower end of the cylinder body 311 is sealed by a lower end cover 317, two sections of cavities are formed in the cylinder body 311 from bottom to top, one section of cavity located at the lower part is longer than one section of cavity located at the upper part, and the diameter of the one section of cavity located at the lower part is smaller than that of the one section of cavity located at the upper part, so that a step surface is formed at the better position of the two sections of cavities. The first piston 312 is disposed in a cavity at a lower end and divides the cavity into an upper cavity and a lower cavity, the piston rod 318 is connected to the first piston 312 and extends out from the lower end of the cylinder 311, such that the upper cavity is a rodless cavity 3111, the lower cavity is a rod cavity 3112, and the lower end of the piston rod 318 is connected to the vertical plate 231 of the mounting plate 23 by means of the hinge block 233. The second piston 313 is disposed in a section of a cavity at an upper end, which may be referred to as a pilot cushion cavity 3113. The spring 314 is disposed in the rodless chamber 3111, and it is easily understood that both ends of the spring 314 respectively abut against the first piston 312 and the second piston 313, in which case the spring 314 has a downward urging force against the first piston 312. The coil spring pad 315 is disposed in the pilot cushion chamber 3113 and is used to push the second piston 313 downward.

It should be noted that: the spring rate of the helical spring pad 315 is much greater than that of the spring 314, and in general, when the spring 314 is compressed to the maximum contraction state under the effective expansion and contraction amount of the spring 314, the upward elastic force of the spring 314 on the second piston 313 still cannot make the second piston 313 leave the step surface, that is: the helical spring pad 315 provides a certain pre-load of the second piston 313 against the step surface even when the spring 314 is in a maximally contracted state.

The first connector 3114 is connected to the rodless chamber 3111, the second connector 3115 is connected to the rod chamber 3112, and the first connector 3114 and the second connector 3115 are connected by a flow guide line 381.

A two-position two-way electromagnetic directional valve is used as the first valve 32 and provided on the pilot line 381, and a check valve that allows hydraulic oil in the rod chamber 3112 to enter the rodless chamber 3111 is used as the second valve 33. The first valve 32 has a first solenoid port 321 and a second solenoid port 322 at both ends thereof. When the first solenoid port 321 is energized, the spool of the first valve 32 is switched to the first position, and at this time, the first valve 32 is turned on, and the first valve 32 is switched to the first state, so that the rodless chamber 3111 is communicated with the rod chamber 3112, hydraulic oil in the rodless chamber 3111 can enter the rod chamber 3112, and hydraulic oil in the rod chamber 3112 can enter the rodless chamber 3111 through the second valve 33, and at this time, the first piston 312 and the piston rod 318 are only acted by the spring 314 with a very small elastic force and are hardly limited by the hydraulic oil, so that the first piston 312 can float up and down relatively freely, so that the cleaning mechanism 20 can float up and down along with the first piston 312 by means of the piston rod 318; when the second solenoid port 322 is energized, the spool of the first valve 32 is switched to the second position, at this time, the second valve 33 is blocked, the first valve 32 is switched to the second state, the rod chamber 3112 and the rodless chamber 3111 are blocked, the hydraulic oil in the rodless chamber 3111 is restricted from flowing, so that the first piston 312 is restricted from moving, and thus, the scavenging mechanism 20 is restricted from moving to form a rigid state.

A pressure sensor 39 may be installed on the first joint 3114 for detecting the pressure of the hydraulic oil in the rodless chamber 3111.

The oil supply pump 37 is connected to the rodless chamber 3111 through an oil supply line 382, and the third valve 34 is provided on the oil supply line 382, and an electromagnetic on-off valve is used as the third valve 34. The third valve 34 has an electromagnetic port, and when the electromagnetic port is powered, the third valve 34 is conducted to conduct the oil supply line 382, so that the oil supply pump 37 can supply oil to the rodless cavity 3111 through the oil supply line 382.

And a first triggering module 361 and a second triggering module 362, which are respectively used for generating a first signal and a second signal to the controller 35, wherein when the second triggering module 362 sends the second signal to the controller 35, the controller 35 controls the electromagnetic port of the third valve 34 to be electrified so that the oil supplementing pipeline 382 is conducted, so that the oil supplementing pump 37 can supplement oil into the rodless cavity 3111 through the oil supplementing pipeline 382. When the first triggering module 361 sends the first signal to the controller 35, the controller 35 energizes the second solenoid port 322, so that the first valve 32 is switched to the first state.

The controller 35 also controls the state of the first valve 32 based on the pressure detected by the pressure sensor 39. Specifically, when the pressure of the hydraulic oil in the rodless chamber 3111 obtained by the controller 35 is lower than the set pressure, the controller 35 deenergizes the first solenoid port 321 and energizes the second solenoid port 322, at which time the first valve 32 is in the second state in which the rodless chamber 3111 is disconnected from the rod chamber 3112, and when the pressure in the rodless chamber 3111 obtained by the controller 35 exceeds the set pressure, the controller 35 energizes the first solenoid port 321 and deenergizes the second solenoid port 322, at which time the first valve 32 switches to the second state in which the rodless chamber 3111 is communicated with the rod chamber 3112.

It should be noted that: the set pressure corresponds to a set impact, which is considered to be stipulated that the set impact should be less than a minimum impact force that causes the disk body 211 of the sweeping disk 21 to be damaged, that is, the disk body 211 is not damaged when the disk body 211 is impacted by less than the set impact force. The set pressure is specifically the pressure in the rodless chamber 3111 when the body 211 of the sweeping disk 21 is subjected to a set impact. Therefore, it is easy to understand that when the pressure detected by the pressure sensor 39 is less than the set pressure, the disk 211 is not damaged even by the impact, and when the pressure detected by the pressure sensor 39 exceeds the set pressure, it is said that the impact applied to the disk 211 is greater than the minimum impact force indicating that the disk 211 is damaged, and therefore, if the rod-less chamber 3111 and the rod-having chamber 3112 are in the cut-off state, this may cause the disk 211 to be damaged because the piston rod 318 is in the rigid state of being not retractable.

The working principle of the above sweeping system is described as follows:

when the sweeper runs on a flat road surface, the motor 22 drives the sweeping disc 21 to rotate so as to sweep the road surface, the sweeping disc 21 is not impacted due to the flat road surface, the pressure detected by the pressure sensor 39 is less than the set pressure, the controller 35 controls the second electromagnetic port 322 of the first valve 32 to be electrified, the first valve 32 is in a second state of disconnecting the rodless cavity 3111 from the rod cavity 3112, at this time, the first piston 312 cannot move due to the disconnection of the rodless cavity 3111 and the rod cavity 3112, at this time, the piston rod 318 is in a rigid state, the sweeping mechanism 20 is in a rigid connection mode with the boom mechanism 10 due to the rigid state of the piston rod 318, and at this time, the sweeping disc 21 of the sweeping mechanism 20 stably performs sweeping operation under the driving of the motor 22.

When the sweeper drives from a flat road to a bumpy road and the bump of the bumpy road on the sweeping disc 21 exceeds a set bump, the pressure detected by the pressure sensor 39 will exceed the set pressure, and at this time, the controller 35 energizes the first solenoid port 321 of the first valve 32 to de-energize the second solenoid port 322, so that the first valve 32 is switched from the second state in which the rodless chamber 3111 and the rod chamber 3112 are blocked to the second state in which the rodless chamber 3111 is communicated with the cylinder chamber, and since the rodless chamber 3111 is communicated with the rod chamber 3112, hydraulic oil can flow between the rodless chamber 3111 and the rod chamber 3112 by the cooperation of the first valve 32 and the second valve 33, so that the first piston 312 can move freely, and at this time, the piston rod 318 is in a floating state, and the sweeping mechanism 20 connected to the piston rod 318 is in a floating connection with the boom mechanism 10 because the piston rod 318 is in a floating state, that is, when the disk 211 is subjected to an impact that may cause the disk 211 to be damaged, the piston rod 318 is switched to the floating state to release the effect of the damage caused by the impact.

When the sweeper drives into the flat road surface again, the driver can manually trigger the first trigger module 361, so that the first trigger module 361 sends a first signal to the controller 35, and after the controller 35 obtains the first signal, the first electromagnetic port 321 of the first valve 32 is controlled to be de-energized and the second electromagnetic port 322 is energized, so that the first valve 32 is switched from a first state in which the rodless cavity 3111 is communicated with the rod cavity 3112 to a second state in which the rodless cavity 3111 is cut off from the rod cavity 3112, and the piston rod 318 is switched from the floating state to the rigid state again, so that the connection mode of the sweeping mechanism 20 and the arm support system is switched from the floating connection mode to the rigid connection mode again.

The sweeping system provided by the embodiment has the advantages that:

1. the utility model provides a cleaning system can make cleaning mechanism 20 and cantilever crane mechanism 10 switch to the connection mode that floats from the rigid connection mode when meeting with the impact that probably causes the damage of the disk body 211 of sweeping the dish 21 to avoid strikeing and cause disk body 211 to damage.

2. The utility model discloses borrow the cooperation that borrows by first trigger module 361 and controller 35 to make the mechanism 20 that cleans that is in the connection mode that floats switch over to rigid connection mode again for the vehicle is gone and is utilized after driving into the road surface again and cleans mechanism 20 and implement stable operation that cleans again.

3. The spring 314 functions as: after the vehicle is driven from the bumpy road surface into the flat road surface again, before the first valve 32 is switched to the second state again, the spring 314 is used for enabling the first piston 312 to be at the lowest end, so that when the first valve 32 is switched to the second state, the extending amount of the piston rod 318 is consistent with the extending amount before passing through the bumpy road surface, and therefore, when the first valve 32 is triggered by the first trigger module 361, the state of the sweeping mechanism 20 can be consistent with the state before passing through the bumpy road surface.

4. The effect of the provision of the second piston 313 and the screw pad is: when an impact exceeding a set impact is applied, it takes a while for the first valve 32 to switch, during which the rodless chamber 3111 and the rod chamber 3112 are still in the blocked or semi-conducting state, the second piston 313 absorbs a portion of the impact in time by compressing the coil spring pad 315 to reduce the impact force on the disc 211 and the piston rod 318 before the first valve 32 is fully switched to the first state.

5. The oil replenishment pump 37 is used to supply hydraulic oil to the rodless chamber 3111. So that the sum of the hydraulic oil in the rodless chamber 3111 and the rod chamber 3112 is constant.

It should be noted that: according to the fluid mechanics principle and the principle of liquid incompressible, an oil storage device, such as an accumulator, is disposed on the flow guide line 381 connecting the rodless chamber 3111 and the rod chamber 3112 for storing excess hydraulic oil flowing from the rodless chamber 3111 to the rod chamber 3112, or for compensating the rodless chamber 3111 for a sufficient amount of hydraulic oil that cannot be provided by the rod chamber 3112.

It should be noted that: the controller 35 described above may be integrated into the overall control system of the sweeping vehicle, and the first triggering module 361 and the second triggering module 362 may preferably be control buttons, which are manually operated.

In a preferred embodiment of the present invention, a guide bar is disposed on the vertical plate 231. A guide rail is arranged at the position below the guide plate 13, and the extending direction of the guide rail is consistent with the floating direction of the cleaning mechanism 20; the lower end of piston rod 318 is connected to riser 231 by hinge block 233. In the present embodiment, the cleaning mechanism 20 does not greatly shake during floating due to the cooperation of the guide bars and the guide rails.
