Description

Technical Field

[0001] The present invention relates to the field of unmanned car washing, and in particular to a single-machine unmanned car washing device that cooperates with pipeline power supply and water supply. Background Art

[0002] A gantry-type unmanned car washing machine refers to a car washing device in which the vehicle to be washed is parked at a fixed position and the gantry moves back and forth according to the type of the vehicle to be washed to achieve the car washing. It can achieve fully automatic car washing according to the set car washing program. Therefore, many existing technologies are currently improving the gantry reciprocating car washing machine to achieve a completely unmanned car washing effect.

[0003] However, the gantry reciprocating car washing machine needs to be fixed in a specific place for use, has high requirements for the site, and has poor car washing effect, which in turn limits its market promotion and application. The main manifestations are as follows: First, the gantry reciprocating car washing machine has a large body size, occupies a large area, and requires a large corresponding site area. As a result, the gantry reciprocating car washing machines on the market cannot be placed in underground parking lots with limited height, communities with limited road width, and other scenes with high demand for car washing. Second, the car washing is not flexible enough, resulting in poor car washing effect. Car owners need to drive the vehicle to the designated position in the gantry reciprocating car washing machine. It is often difficult for car owners to drive into the designated position, or collide with the equipment during the driving process, thereby reducing the unmanned car washing experience. In addition, the car washing range of the gantry reciprocating car washing machine is set, which will cause it to not be well adapted to each type of vehicle, resulting in incomplete and inadequate cleaning of vehicles of certain models.

[0004] In other words, the common gantry reciprocating car washing machines on the market currently have many technical problems in actual application, which restricts the development of the unmanned car washing field. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying 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 belong to the scope of protection of the present invention.

[0026] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0027] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0028] This solution provides a stand-alone unmanned car wash equipment that cooperates with pipeline water supply and power supply. This stand-alone unmanned car wash equipment is different from the traditional gantry-type unmanned car wash equipment. It innovatively adopts pipeline-type unmanned car wash equipment. The external pipeline water supply and power supply provide consumables support for the mobile pipeline-type unmanned car wash equipment, so that the pipeline-type unmanned car wash equipment can wash the vehicle more flexibly. It is particularly worth mentioning that in order to complete the walking function of the pipeline-type unmanned car wash equipment and the structure of the lightweight pipeline-type unmanned car wash equipment, the consumables structure of the pipeline-type unmanned car wash equipment is sacrificed, including the reduction of the water tank volume and the cancellation of the setting of the power supply component of the external fixed power supply. This solution solves these supporting problems through external pipeline water supply and power supply, so that the pipeline-type unmanned car wash equipment can sustainably, flexibly and variably provide car washing services for the vehicles to be washed.

[0029] Specifically, the stand-alone unmanned car washing equipment includes a fixed frame 10, an adapter 20, a telescopic assembly 30 and an unmanned car washing equipment 40 connected in sequence, wherein the adapter 20 is rotatably connected to the fixed frame 10, one end of the telescopic assembly 30 is connected to the adapter 20, and the other end is connected to the unmanned car washing equipment 40, the water and electricity pipelines pass through the fixed frame 10 and the adapter 20, and the telescopic assembly 30 is connected to the unmanned car washing equipment 40.

[0030] In this solution, the unmanned car washing device 40 in the stand-alone unmanned car washing device can independently rotate with the adapter 20 as the center of the circle, and the unmanned car washing device 40 arrives at the set car washing position of the vehicle to be washed and independently completes its own car washing task.

[0031] In order to meet the normal consumables usage requirements of the unmanned car washing equipment 40, each set of water and power pipelines includes at least a water pipeline and a power pipeline, and the water and electric circuits must be set separately. Each set of water and power pipelines includes at least a clean water pipeline, a cleaning liquid pipeline and a power supply pipeline, wherein the clean water pipeline is a pipeline with clean water inside, the cleaning liquid pipeline is a pipeline with built-in cleaning liquid, and the power supply pipeline is an energized wire. In this solution, 220V AC is placed in the power supply pipeline, which meets the conventional domestic electricity demand. Since clean water, cleaning liquid and electric current will affect each other, they must be placed in different pipelines.

[0032] The following is a detailed structural description of each component of the stand-alone unmanned car washing equipment:

[0033] The fixing frame 10 provided in this solution includes a column 11 and a connecting beam 12 placed on the column 11, wherein the column 11 is vertically arranged relative to the ground plane, the connecting beam 12 is arranged perpendicular to the column 11, and the connecting beam 12 is connected to the adapter 20. The column 11 and the connecting beam 12 form an inverted L-shaped structure, and the advantage of such a structural arrangement is that the floor space of the fixing frame 10 is minimized, and a semi-enclosed space is formed between the connecting beam 12 and the column 11, providing an unobstructed moving space for the unmanned car washing device 40.

[0034] In this solution, the connecting beam 12 is placed on the top side of the column 11 . Of course, the connecting beam 12 can also be arranged at a position close to the top side of the column 11 .

[0035] In order to facilitate the processing, transportation and installation of the fixing frame 10, the column 11 and the connecting beam 12 are disassembled and connected, and the connecting beam 12 also includes a disassembled connecting elbow 121 and a connecting crossbeam 122. The two ends of the connecting elbow 121 are respectively connected to the column 11 and the connecting crossbeam 122, which plays a steering role. In the embodiment of this scheme, the column 11 and the connecting beam 12 are connected by a flange, and the connecting elbow 121 and the connecting crossbeam 122 are welded by a splicing pipe. Of course, the connecting beam 12 of the fixing frame 10 is provided with a wire outlet hole.

[0036] The fixing frame 10 is fixedly placed in a car wash, which needs to meet the power supply and water supply requirements for car washing. However, due to the small footprint of the fixing frame 10, it can be placed in residential areas, parking lots, etc. The water and power pipelines placed in the fixing frame 10 also play a role of being protected.

[0037] The adapter 20 can still achieve the effect of free circumferential rotation when the water and electricity pipelines are transferred. The adapter 20 is rotatably connected to the connecting beam column 12. Specifically, the adapter 20 includes a rotatably connected adapter stator 211 and an adapter rotor 212, and is a hollow shaft structure. The adapter stator 211 is fixedly connected to the connecting beam column 12. The water and electricity pipelines enter the adapter 20 from the adapter stator 211 and are led out from the adapter rotor 212. Specifically, a waterway inlet 213 and a circuit inlet 214 are provided on the adapter stator 211, and a waterway outlet 215 and a circuit outlet 216 are provided on the adapter rotor 212. The clean water pipeline and the cleaning liquid pipeline of each group of water and electricity pipelines enter from the waterway inlet 213 and are led out from the waterway outlet 215, and the power supply pipeline enters from the circuit inlet 214 and is led out from the circuit outlet 216.

[0038] The adapter 20 is connected to the telescopic assembly 30. In this embodiment, a mounting hole 217 is provided on the surface of the adapter rotor 212, and the telescopic assembly 30 is connected to the adapter 20 through the mounting hole 217. However, when the adapter 20 rotates, the telescopic assembly 30 will inevitably be driven to rotate together.

[0039] The adapter 20 is vertically connected to the beam column 12. In order to reduce the bearing capacity of the connecting beam column 12, a flange is welded to one end of the pipe shaft 21 of the present solution, and the flange is connected to the connecting beam column 12 to increase the contact area between the two. In addition, considering that the adapter 20 needs to be used outdoors and there are many exposed water pipes, a sheet metal cover can be set outside the adapter 20 to extend the service life of the adapter 20.

[0040] The water and electricity pipelines led out from the adapter 20 are introduced into the telescopic assembly 30. In order to expand the moving range of the unmanned car washing device 40, the telescopic assembly 30 is a telescopic structure. Specifically, the telescopic assembly 30 includes a telescopic rod 31 and a vertical rod 33 connected to each other. The telescopic rod 31 includes at least two telescopic parts 311 connected telescopically. The telescopic rod 31 is radially connected to the adapter 20, and the vertical rod 33 is vertically connected to the telescopic rod 31 and the other end is connected to the unmanned car washing device 40. In this way, the unmanned car washing device 40 can make circular motions of different diameters relative to the position of the slip ring 23. In order to prevent the water and electricity pipelines from being affected by the expansion and contraction of the telescopic assembly 30, the water and electricity pipelines are placed in the telescopic assembly 30 through a drag chain, and the water and electricity pipelines and the other end of the drag chain are connected to the unmanned car washing device 40.

[0041] The vertical rod 33 and the telescopic rod 31 are connected by a transfer elbow 32, wherein one end of the transfer elbow 32 is connected to the telescopic rod 31, and the other end is connected to the vertical rod 33. In order to facilitate the processing, transportation and installation of the telescopic assembly 30, the vertical rod 33 and the telescopic rod 31 are detachably connected. In the embodiment of the present solution, the vertical rod 33 and the transfer elbow 32 are connected by a flange.

[0042] Because the stand-alone unmanned car washing device needs to move frequently during use, and the corresponding telescopic component 30 needs to be extended and retracted multiple times, the present solution also optimizes the structure of the telescopic rod 31, in order to increase the lubricity and wear resistance between the telescopic parts 311, reduce the telescopic noise, and enhance the bearing capacity of the telescopic rod 31.

[0043] Specifically, the telescopic rod 31 includes a plurality of telescopic parts 311 that are telescopically connected. The telescopic parts 311 are sleeved in adjacent telescopic parts 311 and a boss structure is used to embed the two parts. That is, the plurality of telescopic parts 311 are sleeved in sequence, and a boss is provided at the joint position of two adjacent telescopic parts 311. Figure 7 As shown, the telescopic rod 31 of the present solution includes five telescopic members 311 , and the cross-sectional dimensions of the telescopic members 311 gradually decrease from the adapter 20 to the vertical rod 33 .

[0044] like Figure 6 and Figure 7 As shown, the telescopic member 311 is a hollow structure so that adjacent telescopic members 311 can be freely extended and retracted. An outer wear block 3111 is provided on the outer surface of a port on one side of the telescopic member 311, and an inner stop block 3112 is provided on the inner surface; an inner wear block 3113 is provided on the inner surface of a port on the other side of the telescopic member 311, and an outer stop block 3114 is provided on the outer surface, wherein the inner stop block 3112 and the outer stop block 3114 match in shape, and in this embodiment, the inner stop block 3112 and the outer stop block 3114 are designed as a concave-convex structure of mutually matching shapes, which has the advantage that the tube wall of the telescopic member 311 is very thin, only 2 mm, and cannot be fixed with conventional bolts.

[0045] When two adjacent telescopic members 311 extend and retract, the inner wall of the telescopic member 311 sleeved on the outside rubs against the outer wear block 3111 of the inner telescopic member 311, and the inner wear block 3113 on the inner side of the telescopic member 311 on the outside rubs against the inner telescopic member 311, that is, wear blocks are provided between the two telescopic members 311 during telescopic movement, so that the friction assistance during telescopic movement of the two telescopic members 311 can be reduced. In this solution, the thickness of the outer wear block 3111 and the inner wear block 3113 is thin, controlled at only about 2.5 mm, so that the step difference between the telescopic members 311 can be as small as possible.

[0046] When the inner telescopic member 311 extends to the outer limit block 3114 at one end and the inner limit block 3114 of the telescopic member 311 sleeved on the outer side is locked, at this time, the travel of the two telescopic members 311 is the maximum. Correspondingly, the inner telescopic member 311 cooperates with the telescopic member inside it again.

[0047] In this solution, the cross-sectional area of ​​the telescopic member 311 on the outer side is larger, that is, the telescopic member 311 close to the outer side is sleeved on the outer side of the telescopic member 311 on the inner side. At this time, an inner stop block 3112 is provided inside the port position at the head end of the telescopic member 311, and an outer stop block 3114 is provided on the outer surface of the port position at the tail end, and the outer stop block 3114 and the inner stop block 3112 are located in the same plane direction.

[0048] In the embodiment of the present scheme, the telescopic member 311 is a rectangular tube, and the port of each section of the telescopic member 311 is a rectangular cross-section. At this time, the inner limit blocks 3112 are symmetrically arranged on both sides of the port at the head end of the telescopic member 311, the outer wear-resistant blocks 3111 are arranged on the other two sides of the port at the head end, the outer limit blocks 3114 are symmetrically arranged on both sides of the port at the tail end of the telescopic member 311, and the inner wear-resistant blocks 3113 are arranged on the other two sides of the port at the tail end.

[0049] It is worth mentioning that the drag chain is placed in the telescopic rod 31 for movement. In order to prevent the drag chain from being stuck by the gap between the telescopic parts 311, a groove is provided at the port position of the telescopic part 311 to reduce the gap.

[0050] The telescopic assembly 30 is inserted into the unmanned car washing equipment 40, and there is relative rotation between the unmanned car washing equipment 40 and the telescopic assembly 30, and the rotation angle is about 150 degrees. Since the telescopic rod 31 is a cantilever beam with a long cantilever, the stability is poor. In order to avoid breakage between the telescopic assembly 30 and the unmanned car washing equipment 40 during the rotation process, a support flange is welded to the end of the vertical rod 33, and the unmanned car washing equipment 40 is connected through the support flange.

[0051] The telescopic assembly 30 and the unmanned car washing device 40 are connected via a bearing sleeve, a tow chain tail fixing piece is provided at the bottom of the telescopic assembly 30, the tow chain is connected to the tow chain tail fixing piece, and the support flange of the telescopic assembly 30 and the fixing piece of the unmanned car washing device 40 are connected via a wear-resistant bearing sleeve to achieve relative rotation. A tow chain tail fixing piece is also welded on the support flange, and the tow chain is connected to the tow chain tail fixing piece after extending from the vertical rod 33.

[0052] That is to say, the drag chain that is extended from the telescopic component 30 and folded and stacked inside the unmanned car washing device has a fan-shaped rotation space.

[0053] The unmanned car washing equipment 40 at least includes an equipment housing, a control panel, a lifting component connected and controlled by the control panel, a brush position control component, a cleaning brush and a moving component, wherein the moving component is placed at the bottom of the equipment housing to realize the movement of the walking unmanned car washing equipment when the moving instruction of the control panel is obtained, wherein the lifting component, the brush position control component and the cleaning brush are connected in sequence and placed on the equipment housing, and the lifting component at least includes a lifting electric cylinder arranged in the height direction of the equipment housing to lift the cleaning brush in the height direction after obtaining the lifting instruction of the control panel, and the brush position control component controls the cleaning brush to be positioned at a specific position for brushing the vehicle body after obtaining the position adjustment instruction of the control panel. The specific structure of the unmanned car washing equipment will not be described in detail here.

[0054] The working principle of the single-machine car washing equipment with pipeline power supply and water supply is as follows:

[0055] The unmanned car washing device 40 is independently rotatably connected to the fixed frame 10 through the telescopic assembly 30 and the adapter 20. When the unmanned car washing device 40 moves actively, it can drive the corresponding telescopic assembly 30 to telescope or the adapter 20 to rotate, so that the unmanned car washing device 40 can move freely within the set position range. The water and electricity pipelines in the fixed frame 10 are correspondingly connected to the unmanned car washing device 40 to supply power to it, so that the unmanned car washing device can continue to work independently for a long time to meet the requirements of unmanned car washing.

[0056] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
