[0002] With the increase in the number of vehicles in the city, the phenomenon of roadside parking affecting road cleaning and maintenance operations has gradually increased, and the contradiction has become increasingly prominent. The pollution at the roadside parking spaces is serious, and the residual dust can reach more than 200g / m2, and the existing operating equipment and operating processes cannot effectively remove the residual dust and other garbage in the parking spaces. When the roadside parking is left, the exposure of pollutants seriously affects the appearance of the city and may also cause dust pollution. Therefore, how to carry out cleaning and maintenance operations in the roadside parking area and effectively reduce the residual dust in the area has become an urgent problem to be solved. Road cleaning equipment in the roadside parking area helps to improve the environmental sanitation level of the capital and improve the living environment of the capital's residents.

DETAILED DESCRIPTION

[0027] The structure of the present invention is shown in Figure 1 , Figure 7 A road surface cleaning device for a roadside parking area comprises a lifting mechanism, a chain retracting and extending mechanism, a dust suction trolley and a chain.

[0028] 1. Lifting mechanism

[0029] It consists of a mounting frame, a lifting push rod, a slide block, a mounting plate, a rotating frame, a rotating shaft and a limit device. The mounting frame is connected to the road sweeper, the mounting plate is connected to the rotating frame, the lifting push rod pushes the mounting plate, and the rotating frame moves up and down within the range of motion of the slide block. The rotating shaft is connected to the chain row retracting mechanism, so that the retracting mechanism can rotate freely and move up and down within a specific range. Its main structure is as follows: Figure 2 shown.

[0030] 2. Chain retracting and extending mechanism

[0031] It consists of a rotating plate, side plates, lining plates, barrel cores, motors, rollers, etc. The side plates and barrel core form a specific space to limit the movement of the chain. One end of the chain is fixed on the barrel core, and the other end is connected to the dust collection trolley. The first reduction motor is connected to the built-in barrel core. The motor drives the barrel core to rotate so that the chain is coiled on the barrel core to achieve chain recovery. The second reduction motor is connected to the chain roller. The motor drives the roller to rotate. The roller pushes the chain to move outward to achieve release. The chain retraction and release drives the dust collection trolley to move forward and backward. Its main structure is as follows: Figure 3 shown.

[0032] 3. Vacuum cleaner

[0033] It consists of a base plate, a travel motor, universal wheels, auxiliary wheels, a dust collector head, a dust collector tube, a connecting block, a sensor, etc. The motor drives the universal wheels to rotate, which can achieve lateral movement. The dust collector heads are located on both sides of the base plate. The dust collector heads are strip-shaped and connected to the dust collector tube at the rear. They are used to absorb garbage from the road surface. Brushes or rubber sheets can be installed on the ground-touching edges to prevent scratching the ground during travel. The chain drive to move the trolley forward and backward is combined with the lateral movement brought about by the rotation of the universal wheels of the trolley drive motor. The trolley can perform fan-shaped reciprocating motion with the rotating axis of the lifting mechanism as the center and the length of the chain as the radius, thereby achieving a covering dust collection operation under the vehicle. For structural parts of the automatic dust collector trolley, see Figure 4 Shown (without housing).

[0034] Universal wheel: The structure of the universal wheel is as follows Figure 5As shown in the figure, it consists of two offset mounted wheel discs and a connecting shaft. The wheel discs are equipped with rollers. Because the roller shaft is perpendicular to the connecting shaft and the rollers cover the entire outer edge of the disc, the rollers in contact with the ground can move freely forward and backward in the axial direction, and the dust suction trolley can realize passive forward and backward movement; when the universal wheel contacts the ground, the motor drives the universal wheel to rotate, and the roller shaft is parallel to the direction of the friction force of the ground, so that the wheel disc can realize active movement in the radial direction, and the dust suction trolley can realize lateral movement. Its movement direction is shown in the figure. Figure 7 as shown in .

[0035] 4. Chain row:

[0036] See also Figure 6 As shown, the chain is composed of a chain body, a connecting piece, a connecting shaft, a locking spring pin and other parts. The connecting piece is fixed on the chain body with rivets and is linked to another chain body through a connecting shaft. The connecting piece drives the chain body to rotate around the connecting shaft. The locking spring pin is a cylindrical pin with a conical surface. When the spring pin moves inward due to external force and disengages from the spring pin hole on the connecting piece, the connecting piece can rotate freely around the connecting shaft. At this time, the connecting piece blocks the spring pin from popping out. When the connecting piece drives the body to rotate to a specific angle, the two chain bodies contact and reach the rotation stop point, which can realize free bending of the chain within a specific angle. When the center of the spring pin hole on the connecting piece rotates to the center position of the spring pin, under the action of the spring, the spring pin pops out and inserts into the spring pin hole to lock the connecting piece. At this time, the chain is in a horizontal fixed state.

[0037] 5. Controller

[0038] The controller is used to control the movement of various parts of the road sweeping equipment in the roadside parking area, including the lifting and lowering of the lifting mechanism, the retraction and extension of the chain row, the dust suction car, and the display and upload of on-site data. The controller does not belong to the invention of the present invention, but is an existing control technology. Therefore, no specific circuit structure diagram is given, and only the function is described as follows: the control core generally adopts a programmable controller (PLC), and an ARM development board, a single-chip microcomputer, etc. can also be used. The controller also has electrical equipment such as a transformer, a motor driver, a relay, an air switch, and an overload protector. The transformer converts the power supply of the road sweeper to the voltage required by different equipment and provides stable support. The controller can be operated by a set of buttons, or by special software installed on a computer (industrial control computer, desktop or notebook), or by a special touch screen. The controller status can be displayed on a computer screen, a touch screen or other display devices. The controller can realize two modes: manual operation and automatic operation. In the manual operation mode, the driver observes the surrounding status of the car through the camera on the automatic dust suction car, and can operate the car movement through an operating handle or a special touch screen. In the automatic operation mode, the driver issues the start operation command through a button or a dedicated touch screen, and the controller controls the car to cruise and cover the vacuum cleaner once within a parking space according to a specific track. When encountering an obstacle, the car automatically retreats. The controller can be connected to the motor driver, sensor, camera and other equipment on the vacuum cleaner car through cables or wireless connections.

[0039] See also Figure 7 As shown in the figure, when the cleaning equipment is running, the status and movement of each component are described as follows:

[0040] The dust collection trolley moves laterally and forwards and backwards: the internal chain is limited by the width of the side plates and the inner lining plate of the retracting mechanism, and the chain spring pin loses its limiting effect. The chain is in a free curling state between the two inner lining plates. When the retracting mechanism roller and the barrel core motor are powered on and rotate clockwise in the same direction, the chain moves outward from the inside of the retracting mechanism under the friction of the rollers. Since the chain spring pin loses the constraint of the inner lining plate and the chain is restricted to a horizontal position by two sets of rollers, the chain pin shaft pops out under the action of the spring, locking the connecting piece to rotate. At this time, the extended chain is in a horizontal fixed state. As the chain continues to When the chain is extended outward, the dust collector trolley moves forward passively, realizing the chain extension and forward movement of the dust collector trolley; on the contrary, when the roller of the retracting and releasing mechanism and the barrel core motor are powered on and rotate counterclockwise in the same direction, the dust collector trolley moves backward due to the inward pulling force of the chain, and the spring pin is separated from the pin shaft hole on the connecting plate under the external force provided by the inner lining plate, and the chain is in a curlable state. The chain in the internal free curling state will not be excessively curled or overlapped due to the limited contact surface of the chain body, so as to avoid squeezing the air pipe passing through the inside. Driven by the barrel core, the chain is more regularly and tightly coiled on the barrel core. The motor is repeatedly powered on and reversed to realize the extension and retraction of the chain, and the dust collector moves forward and backward. When the dust collector trolley travel motor is powered on, the universal wheel rotates, and the dust collector trolley can move horizontally in the direction of an arc with the rotating axis as the center and the distance from the trolley to the rotating axis as the radius. The lateral and forward and backward movement of the vacuum cleaner can realize the cleaning operation in a "fan-shaped" trajectory under the vehicle.

[0041] When the chain is completely retracted into the retracting mechanism, the dust suction trolley is fixed at the end of the retracting mechanism, and when the limit mechanism is opened to limit the rotation of the retracting mechanism, the lifting mechanism can lift the dust suction trolley and the retracting mechanism off the ground under the action of the electric push rod. At this time, the site can be transferred. When arriving at the next work site, the lifting mechanism places the dust suction trolley and the retracting mechanism on the ground, and the limit device is closed. At this time, cleaning operations can be carried out.

[0042] The suction source from the road sweeper is connected to the air pipe interface of the retracting and releasing mechanism through the air pipe. The air pipe interface and the barrel core air pipe are connected with a shaft sleeve, and a sealing ring is installed inside to ensure air tightness. At the same time, the external suction source air pipe will not be twisted, deformed or blocked as the barrel core rotates. The barrel core air pipe is connected to the position of the dust suction head of the dust suction trolley through the steel wire soft air pipe inside and inside the chain row (the air pipe layout is as follows Figure 7 The suction source provides dust suction for the road cleaning equipment in the roadside parking area.
