Wheel washing machine

Abstract

The invention discloses a wheel washing machine, belongs to the technical field of wheel washing machine manufacturing in environmental protection equipment, and aims to solve the technical problem that wheels of an engineering vehicle are not easy to clean. In order to solve the problems, the technical scheme adopted by the invention is as follows: wheels of the engineering vehicle are rolled on a roller provided with bulges arranged at intervals in a staggered manner, and the bulges arranged at intervals in the staggered manner enable the surface of the top of the tire to locally generate temporary deformation of inward sinking or local outward bulging, so that a groove in the top of the tire is thinned or expanded; the mud strips in the grooves are extruded to be thinned or the expanded mud strips in the grooves automatically fall off, and the thinned mud strips naturally fall off when the tire rotates to leave the bulges and returns to normal. Through combined application of the wheel washing machine, the working efficiency can be better improved in the field of cleaning of wheels of engineering trucks. The wheel washing machine can also be used for washing wheels in chemical pollution areas, epidemic areas and the like.

Description

Technical Field

[0001] The technical field of this invention is the manufacture of wheel washing machines in environmental protection equipment, and more specifically, the manufacture of machines for washing the wheels of construction vehicles at construction sites. Background Technology

[0002] When construction vehicles approach or leave the soil loading area, the top of the tires (the part of the tire that contacts the road surface) inevitably runs over clods of soil scattered on the ground. The clods are squeezed into the grooves of the tires, forming mud strips that are hard, inelastic, and difficult to clean.

[0003] Currently, most construction site wheel washing methods involve two approaches: wheel washing pools and grating-type wheel washing machines. Wheel washing pools are typically recessed cement pools with ramps at the front and rear, a flat bottom, and are approximately 3-5 meters long and 3.5 meters wide, with a water depth of about 25 centimeters. The vehicle slowly enters the pool from one end of the ramp; as it continues to move slowly, the tires roll through the water one by one, and the vehicle exits from the other end, completing the washing process. Grating-type wheel washing machines are approximately 2-6 meters long and 3.5 meters wide, consisting of a grid of interconnected, perforated square tubing welded together. The frame is laid flat on the road surface, with vertical water spraying frames set longitudinally on both sides. When a construction vehicle drives over the grating, its tires are washed by the upward water spray from the grating and the inward water spray from the vertical frames on both sides. Alternatively, the construction vehicle may pause on the grating to receive the above-mentioned washing before driving away. The two existing commonly used wheel washing methods can wash away most of the dirt on the tire surface. However, they only wet the surface of the mud strips stuck in the grooves between the rubber blocks on the top of the tire. Most of the mud strips cannot be washed away. They do not soften the mud strips in the grooves, nor do they change the shape of the mud strips. The mud strips are still tightly stuck in the grooves, and the binding state between the mud strips and the grooves is not changed. Summary of the Invention

[0004] Technical problem solved: The wheel washing machine provided by this invention solves the problem of mud strips not being cleaned from the grooves on the top of the tires of engineering vehicles by existing wheel washing methods such as grid-type wheel washing machines and wheel washing pools.

[0005] Technical solution

[0006] To address the problem of incomplete cleaning of mud strips from the grooves on the top of engineering vehicle tires, the solution provided by this invention is as follows: The wheels of one axle (both ends) of the engineering vehicle are driven sequentially or simultaneously onto the rolling device of this wheel washing machine, stopping between two horizontally parallel rollers. The drive device located on the outside of the rolling device is activated, driving the drive shaft to rotate the rollers on the drive shaft. This causes the top of the tire to repeatedly roll against the rollers with multiple protrusions, resulting in repeated compression or expansion of the grooves on the top of the tire, altering the shape of the mud strips in the grooves and greatly reducing the adhesion area between the mud strips and the groove walls. Multiple water spray holes on the horizontal pipes on the outside of the rollers then repeatedly rinse the top of the tire, causing the mud strips to detach on their own.

[0007] To achieve the above solution, the wheel washing machine technical solution provided by the present invention is as follows: A rail is longitudinally installed on both sides of the bottom of the wheel washing machine pit at the exit of the construction site (in the direction of vehicle travel). A wheel washing machine rolling device with rotatable rollers is installed on the rail, and a rinsing frame is installed on the rolling device. The rolling device is a rectangular box with openings at the top and bottom, connected and fixed by front, rear, left, and right side panels. The upper end of the box is at the same height as the adjacent road surface. Two rotatable rollers are horizontally arranged side-by-side in the upper middle part of the box. The rollers are provided with multiple protrusions or corrugated plates with uneven surfaces and multiple protrusions. A driving device or locking device is respectively installed on the outer left and right sides of the box. A hydraulic cylinder for moving the box back and forth is longitudinally installed on the outer left and right sides of the box. A horizontal pipe with multiple water spray holes is installed on the upper part of the inner side of the front and rear side panels (near the rollers). The two ends of the horizontal pipe are connected and fixed to the upright rinsing frame.

[0008] Working Principle: The mud strips in the tire grooves of engineering vehicles are inelastic but have a certain degree of hardness. They are mainly subjected to the strong clamping force of the rubber blocks on both sides of the groove. The working principle of this wheel washing machine is that the top of the tire makes rolling contact with the protrusions and depressions on the roller, causing the grooves on the top of the tire to repeatedly concave inward and narrow or bulge outward and expand. This causes the mud strips in the grooves on the top of the tire to be squeezed, narrowed and deformed, no longer clamped, and greatly reduced to natural adhesion to the groove walls and top. As the tire rotates, the mud strips are naturally thrown out and fall off. When the top of the tire contacts the protrusions, the grooves in the gaps between the protrusions or in the depressions of the corrugated plate bulge outward and expand to both sides under the action of tire pressure. The mud strips in them loosen and move out of the groove asynchronously. After several contacts with the roller, the mud strips fall off naturally.

[0009] Positive effects

[0010] This wheel washing machine, by employing a continuous tire-compacting roller mechanism and utilizing a central nozzle and front and rear horizontal pipes for comprehensive tire washing, significantly reduces worker workload. It eliminates the need for workers to drag hoses and hold water guns while washing tires in traffic, thus preventing accidents between workers and vehicles. This improves washing efficiency, reduces vehicle waiting time, indirectly reduces fuel consumption and improves transportation efficiency, and also minimizes environmental damage caused by incomplete cleaning. Furthermore, because of its comprehensive tire-washing spray nozzles, this machine eliminates the need for existing wheel washing tanks (some construction sites use both methods simultaneously).

Specific Embodiment 1

[0026] The following further elaborates on the present invention in conjunction with the drawings in the specification. The specific embodiments listed in this specification are preferred design solutions for the vehicle and cargo total weight less than or equal to 80 tons.

[0027] Figure 1 This is a three-dimensional schematic diagram of the external structure of the wheel washer. In the figure, the upper part is the flushing frame and the lower part is the rolling device. The arrows in the figure indicate that the four corners of the upper flushing frame are basically aligned and moved downward and stacked on the rolling device. Stacking the flushing frame on the rolling device is the working state of the wheel washer.

[0028] As can be seen from the above figure, on both sides of the flushing frame of the wheel washer, there is an internally-through "day" - shaped frame welded with iron square pipes of about 80 mm. The two "day" - shaped frames on both sides are arranged upright and opposite to each other, and the two inner sides of the lower part are welded into a whole with the horizontal pipe 13 to form the flushing frame. The height of this "day" - shaped frame is about 1.4 meters and the width is about 1 meter. There is a water baffle 11 on the outside of the upper half, and the square pipes forming the frame inside the upper half are as Figure 1As shown in Figure 10 of the Chinese diagram, multiple holes with a diameter of about 2 mm are distributed and set as water spray holes, with a hole spacing of about 15 cm. The water spray direction of the water spray holes set here is horizontally inward, used to wash the outer side of the tire. The iron cross pipes 13 arranged on both sides of the lower part of the washing frame have a length of about 3.34 m, and are made of square pipes or round pipes with a diameter of about 40 mm. Figure 1 As shown in Figure 13 of the Chinese diagram, there are two square pipes on one side. Figure 3 As shown in Figure 13 of the A-A Chinese diagram, there is one square pipe. Figure 8 As shown in Figure 13 of the Chinese diagram, it is a round pipe. In actual production, any one of the following methods can be selected: two square pipes or two round pipes, or one square pipe and one round pipe (round + square), or as Figure 8 As shown in Figure 13 of the Chinese diagram, only one round pipe is used without a square pipe, or Figure 3 As shown in Figure 13 of the Chinese diagram, only one square pipe is used; in short, multiple water spray holes with a diameter of about 2 mm and a spacing of about 20 - 40 mm and a horizontal included angle of about 45 - 90 degrees with the upper middle part of the wheel washer are arranged on the cross pipe 13 within a length range of about 1.1 m from both ends to the middle; the water spray holes set on this cross pipe are used to spray water to wash the top of the tire, and the preferred water spray direction is obliquely upward from the front and back to the middle.

[0029] At Figure 1 As shown in Figure 7 of the outer side of the lower right corner of the washing frame in the upper Chinese diagram, the water inlet pipe is shown. The diameter of this water inlet pipe is about 7 cm, and it is connected to a water pump placed in the water tank through a wire spiral hose with a corresponding caliber. The water pump is connected to the water pump power switch set in the distribution box through a wire. The output pressure of the water pump is about 2.5 kg per square centimeter, and the power of the water pump is about 2.5 kilowatts per hour. Since the washing frame is integrally internally interconnected, the water inlet pipe can be set at any position of the washing frame according to needs; similarly, the water supply pipe of the central nozzle shown in Figure 14 comes from the plumbing external thread (joint) 31 welded to the washing frame, and this external thread joint can also be set at any position of the washing frame according to needs. That is to say, the water inlet pipe shown in Figure 7 and the external thread (joint) 31 connected to the central nozzle 14 in its upper right part are in the positions shown in the figure for the convenience of understanding and observing the design intention of the present invention, and may not be the best position in actual production, and can be set elsewhere according to actual needs, such as at the corresponding position on the outer side of the lower part of the "day" - shaped washing frame on the left side. The central nozzle 14 is arranged at the middle position of the lower part of the washing frame of this wheel washer, and its installation position is as Figure 1 As shown in Figure 14 of the upper Chinese diagram, this central nozzle is used to wash the inner side of the tire, and its appearance shape is as Figure 7As shown, two manufacturing methods of the central nozzle are listed here: The first manufacturing method of the central nozzle is: As shown in the upper figure of the above-mentioned figure, cut about 9 cm from a circular iron pipe with a diameter of about 40 mm. Since the purpose of this central nozzle is to spray water to wash the inner side of the tire, multiple holes (as shown in the figure) with a diameter of about 2 mm are set at an angle of about 30 degrees with the horizontal on the upper sides of both sides of this iron pipe as water spray holes; The second manufacturing method of the central nozzle is: Cut about 9 cm from a square iron pipe with a diameter of about 30 or 40 mm, and set the diagonal of the cross-section horizontally or vertically. As shown in the icon 10 in the lower middle figure, on the two upper surfaces of this square pipe, set multiple holes with a diameter of about 2 mm as water spray holes; Weld sealing plates at both ends of the above-mentioned square pipe or circular pipe, drill a hole with a diameter of about 15 mm in the center of the sealing plate as a silt removal hole, weld an external thread joint of a plumbing fitting around the silt removal hole, and tighten an internal thread plug in the plumbing fitting on the external thread. Drill a hole with a diameter of about 15 mm at the lower middle position of the circular pipe or square pipe shown as the central nozzle, and weld an external thread joint of a plumbing fitting at this hole for (as shown in the icon 31 in the upper middle figure) connecting with the external thread 31 at the lower part of the outer side of the "day" - shaped flushing frame and the central nozzle 14 through plumbing iron pipes and fittings to achieve the purpose of supplying water to the central nozzle and washing the inner side of the tire. Figure 7 As shown in the icon 10 in the lower middle figure, on the two upper surfaces of this square pipe, set multiple holes with a diameter of about 2 mm as water spray holes; Weld sealing plates at both ends of the above-mentioned square pipe or circular pipe, drill a hole with a diameter of about 15 mm in the center of the sealing plate as a silt removal hole, weld an external thread joint of a plumbing fitting around the silt removal hole, and tighten an internal thread plug in the plumbing fitting on the external thread. Drill a hole with a diameter of about 15 mm at the lower middle position of the circular pipe or square pipe shown as the central nozzle, and weld an external thread joint of a plumbing fitting at this hole for (as shown in the icon 31 in the upper middle figure) connecting with the external thread 31 at the lower part of the outer side of the "day" - shaped flushing frame and the central nozzle 14 through plumbing iron pipes and fittings to achieve the purpose of supplying water to the central nozzle and washing the inner side of the tire. Figure 1 As shown in the icon 31 in the upper middle figure, connecting with the external thread 31 at the lower part of the outer side of the "day" - shaped flushing frame and the central nozzle 14 through plumbing iron pipes and fittings to achieve the purpose of supplying water to the central nozzle and washing the inner side of the tire. Figure 1 It shows an installation method of the central nozzle. In actual application, according to specific vehicle models, there are also ways of arranging 2 or 3 central nozzles in parallel.

[0030] All the interiors of the above - mentioned flushing frames are completely through - connected, all made of iron, with a wall thickness of all greater than or equal to 2 mm, the water - retaining plate has a thickness of about 0.45 mm, and all are painted with more than 2 coats of anti - rust paint.

[0031] The rolling device located at the lower part of this wheel washer, as Figure 1 shown in the lower middle figure, is mainly composed of the surrounding plates around and the rollers inside. As seen from Figure 1 the figure, the surrounding plates located at the front, rear, left, and right are connected and fixed to each other (preferably bolt - connected) to form a rectangular frame with openings at the top and bottom. Among them, the front and rear surrounding plates 12 preferably have a length of about 3.5 m, a width (up and down in the figure) of about 0.5 m, and a wall thickness not less than 12 mm. The left and right surrounding plates 18 preferably have a length of about 1 m, a width of about 0.5 m, and a thickness not less than 12 mm (preferably 16 mm). The cross - section of the front and rear surrounding plates is as Figure 8 shown in the icon 12 in the figure, which is a "[ - " - shaped steel with an opening facing outwards. As seen from the figure, a cross - tube 13 protection groove welded with iron plate strips with a thickness not less than 12 mm is set on the upper part inside the front and rear surrounding plates 12. The function of this cross - tube protection groove is to support the cross - tube and prevent the cross - tube from being crushed and deformed. The inner width of the groove is slightly larger than the outer diameter of the cross - tube (if the cross - tube 13 adopts Figure 3The square horizontal pipe shown in Figure 13 has a groove width slightly larger than its diagonal. The groove depth (groove height) is similar to the groove width. When two horizontal pipes are installed, the cross-section of the horizontal pipe protection groove is a flat-topped "mountain" or "W" shape. A triangular support plate is welded and fixed to the bottom of the horizontal pipe protection groove to the surrounding plate 12. The spray holes on the square or round horizontal pipes are as follows... Figure 8 As shown in Figure 10, the water should be sprayed at an angle of approximately 45 to 90 degrees toward the center of the wheel washing machine.

[0032] Figure 8 The buffer plate (22 in the middle of the diagram) covers the gap between the front and rear panels of the wheel washing machine and the edge support plate 21 of the pit, and prevents the tires from rolling over the upper edges of the front and rear panels of the wheel washing machine's rolling device, causing the other end of the rolling device to lift up. Therefore, the buffer plate is set horizontally. The buffer plate is at least 20 mm thick, about 40 cm wide, and about 1 meter long. It is positioned opposite the protruding area on the roller, with two plates on each of the front and rear panels. To facilitate sludge removal, the buffer plate is designed to be flip-up, with its inner edge basically flush with the upper edges of the front and rear panels. It is fixed to the upper edges of the front and rear panels by welding hinges, and its outer edge rests naturally on the edge support plate 21 of the pit.

[0033] The above provides a basic description of the front and rear panels 12 of the long side of the rectangular frame that constitutes the rolling device of this wheel washing machine. The following describes the left and right panels 18 of the short side of the rectangular frame that constitute the rolling device of this wheel washing machine. Figure 10 This is a schematic diagram of the left and right side panels. The image above is (in conjunction with...) Figure 1 The left side panel of the rolling device (shown in the lower image) and the right side panel (shown in the lower image) are shown in the images. The main body of both panels consists of a vertical iron plate approximately 1 meter long, 0.5 meters wide (height), and 20 millimeters thick, welded together with a long, rectangular pad placed flat below it. The long, rectangular pad, approximately 1 meter long, 7 centimeters wide, and 20 millimeters thick, is used to increase the load-bearing area of ​​the pit bottom. The upper part of the left and right panels has two large circular holes horizontally, with multiple smaller holes evenly distributed around them. Figure 9 , Figure 9 Icon 18 shows the left and right side panels mentioned here; Icon 23 shows the lateral protrusion in the middle of the wheel hub, extending outward from the large circular holes provided on the left and right side panels. Therefore, the diameter of the two large circular holes on the upper part of the left and right side panels is slightly larger than the outer diameter of the protrusion of the wheel hub 23. Multiple small holes evenly distributed around the large circular holes are used for bolt connection and fixation between the wheel hub and the left and right side panels. Therefore, the hole spacing of the multiple small holes corresponds to and matches the hole diameter and the bolt holes on the wheel hub; the two large circular holes extend outward from the middle of the left and right side panels.

[0034] The axis is set on both sides, and the center distance between the two large round holes is about 40 cm. The center of the large round holes is about 16 cm from the upper edge of the left and right side panels. Figure 10The left side panel shown in the upper middle figure has two oblong sludge removal holes on the lower horizontal part. The sludge removal holes are approximately 230 mm long and 80 mm high. The lower middle circular hole is the water supply pipe hole for the central nozzle, with a width and height of approximately 80 mm. The four holes on the lower horizontal part of the right side panel shown in the lower middle figure are the bolt holes for mounting the drive device bracket, with a diameter of approximately 17 mm.

[0035] from Figure 1 The image below clearly shows that within the rectangular rolling device frame composed of the front, back, left, and right side panels, two rollers are horizontally arranged; combined with... Figure 2 and Figure 3 As can be seen: two rollers are arranged side by side in parallel; the highest point of each roller is approximately the same height as the upper edge of the surrounding plate; a through-type drive or follower shaft is installed inside each roller; multiple staggered protrusions are arranged within approximately one-third of the length of each end of the outer side of the roller; the two ends of the drive or follower shaft inside the roller pass through or are fixed to the left and right surrounding plates. The rollers are approximately 3.3 meters long, made of seamless steel pipe, with a wall thickness of ≥12 mm and an outer diameter of approximately 280 mm. Figure 4 As shown: Figure 4 The diagram shows the connection and distribution of the roller 3 (wall) and the protrusions 2. As seen in the diagram, the solid protrusions are attached to the outside of the roller wall at their base. The solid protrusions with cylindrical supporting spherical surfaces are welded to the outside of the roller wall at their base. The protrusions are approximately 40 mm in diameter and 35 mm in height. The gap between alternating rows of protrusions is approximately 30 mm wide, and the minimum distance between adjacent staggered protrusions is approximately 10 mm. The principle of the protrusion arrangement is staggered distribution with minimal gaps (approximately 10 mm). Through repeated observations on-site, the inventors discovered that fully loaded 4-wheel and 8-wheel engineering vehicles carrying sand do not experience tire blowouts when driving over a 20 cm transverse gap in a cement road surface, and do not experience tire blowouts when driving over existing grid-type wheel washing machines with half of the tires suspended in the air. Based on these observations, the inventors deduced and set the ratio of the top area of ​​the protrusions to the gap between them in this wheel washing machine to the aforementioned relationship, i.e., the top area of ​​the protrusion is larger than the area of ​​the gap between the protrusions, and the filling of the gaps by falling mud strips is appropriately considered (thus determining the height of the protrusions, etc.). To save costs and reduce steel usage, the protrusion can be umbrella-shaped or mushroom-shaped. Specifically, the top of the protrusion can be made from industrial triangular, oval, square, pentagonal, hexagonal, or other polygonal plate scraps of appropriate thickness (about 6 mm, about 40 mm in length and width), stamped into a raised top material with a height (difference in height between the raised surfaces) of about 10 to 30 mm. The bottom can be made from welded scrap pipes with a diameter of about 20 mm or square or hexagonal supports with a height of about 25 mm. Waste grinding balls from cement plants and other sources can also be used to process part or all of this protrusion.

[0036] The two rollers of this washing machine are respectively fitted over the drive shaft and follower shaft, which are about 3.6 meters long. Rings for supporting the rollers are fitted at both ends of the drive shaft and follower shaft. The thickness of the support rings is about 20-50 mm (40 mm is selected in this embodiment), the outer diameter is equal to the inner diameter of the rollers, and the inner diameter of the support rings is equal to the outer diameter of the shafts on which they are fitted. The support rings are hammered into both ends of the seamless steel pipe used to make the rollers. The rollers are connected and fixed to the drive shaft or follower shaft by welding or other methods (detachable method) through the support rings.

[0037] The drive shaft and follower shaft of this wheel washing machine adopt the technology of existing tractor-trailer follower shafts (axles), 13-ton load-bearing axles, and wheel hubs from cargo trucks. See Figure 9 As shown in the figure, the drive shaft (same as the follower shaft) shown in icon 4 has different diameters in each section. One end is equipped with an inner bearing 24 and an outer bearing 25. The inner and outer bearings are respectively equipped with a sealing ring 26 and a sealing cover 27. The inner and outer bearings are fitted with a hub 23 (top and bottom in the figure). The hub is installed and fixed to the left and right side plates 18 by bolts. The fastening nut 30 presses down on the outer bearing. The pulley 28 is installed and fixed to the outermost (right) end of the drive shaft by a key 29 groove.

[0038] Figure 9 The lower part is marked with dimension lines a and b. Segment a indicates the prior art shaft segment, including the existing sealing cap shown in icon 27 outside the left dimension line. Segment a is used for Figure 1 The left end of the drive shaft (shown in icon 4) and the right end of the follower shaft (shown in icon 5) are assembled with the left and right side panels; the assembly method shown in section b + section a represents... Figure 1 The right end of the drive shaft is shown in Figure 4; Figure 1 As shown in Figure 4, the right end of the drive shaft is designed to mount a motor, rather than a pulley. The reason for this is that using a three-phase AC asynchronous variable frequency speed control motor to drive the drive shaft is one of the drive methods for this wheel washing machine; additionally... Figure 1 The design of the drive unit as a traditional electric motor acceleration and deceleration mechanism affects the visual effect of this wheel washing machine and makes it difficult to understand the relationship between the right side panel 12 and the central nozzle water supply pipe shown in icon 14.

[0039] Figure 5 This is a schematic diagram of the traditional drive method used in this wheel washing machine. In actual manufacturing, the front-to-back, top-to-bottom positions of the components, the direction of the exposed parts of the reducer's input and output shafts, and the power transmission belts are not limited to the three types shown in the diagram; four belts are used. Figure 9 The pulley shown in Figure 28 is more stable and durable in practical applications. (The above...) Figure 5In this embodiment, a power transmission method of motor 6 → reducer 19 → drive shaft pulley 28 is adopted. A 7.5 kW AC three-phase four-pole motor 6 is installed on the drive device bracket of this washing machine. The outer diameter of the pulley installed on the motor is about 100 mm. The outer diameter of the pulley on the input shaft of reducer 19 is about 300 mm. The reducer is a 350 type with a transmission ratio of 48:1. The outer diameter of the pulley on the output shaft of reducer is about 100 mm. The outer diameter of the pulley installed on the drive shaft 4 (right end) is about 300 mm (to achieve a drum speed of about 10 revolutions per minute). The motor pulley is connected to the pulley on the input shaft of reducer using a triangular transmission belt. The pulley on the output shaft of reducer is connected to the pulley 28 on the drive shaft 4 using a triangular transmission belt. The method for connecting the pulleys with the triangular transmission belts described above is as follows: Select rubber belts of the appropriate model and length that match the pulley belt grooves and fit them into the grooves of the pulleys respectively. Then, tighten and secure the fastening bolts (threads) of the reducer and motor according to the operating specifications. Before the transmission belts are fitted, the reducer and motor have been placed on the drive unit bracket in advance and temporarily fixed to the corresponding positions on the drive unit bracket by their respective fastening bolts.

[0040] Drive unit bracket such as Figure 1 As shown in icon 15 in the lower right corner, it is an L-shaped section (or other shapes made according to actual needs) with the upper end tilted 90 degrees to the right, welded from an iron plate approximately 20 mm thick, with a large surface approximately 400 mm wide and a small surface approximately 150 mm wide. Bolts are passed through the fastening bolt holes provided on the small surface (small surface of the L) of the drive device bracket (approximately 150 mm wide) and installed and fixed to the lower middle part of the outside of the right side panel 18.

[0041] exist Figure 1 In the rolling device shown in the lower middle diagram, the left end of the follower shaft (marked by icon 5) has a locking device, which is not shown in this diagram because it is inconvenient to illustrate. Also, the water inlet pipe 7 and the water inlet pipe of the central nozzle 14 in the upper diagram are placed on the right side of the diagram for illustrative purposes; in actual manufacturing, placing them on the left side of the diagram would be more practical. These features actually exist. Figure 2 Icon 8 and Figure 3 The icon in the lower image is marked; its detailed settings are as follows: Figure 6 As shown, Figure 6The upper middle figure is the front view of the locking device, and the lower figure is the side view of the locking device. Icon 8 in the figure shows the locking wheel, which is made of cast iron or wrought iron plate, with a thickness greater than 12 mm and less than 100 mm. The thickness shown in the figure is about 16 mm, preferably 60 mm. The inner diameter of the locking wheel is equal to the outer diameter of the follower shaft end, and it is fitted onto one end of the follower shaft 5. The inner circle of the locking wheel is provided with a keyway that matches the end of the follower shaft. The outer diameter of the locking wheel is about 300 mm, and the outer edge of the locking wheel is provided with multiple sawtooth-shaped notches as shown in the figure along the circumference. Icon 20 in the figure shows a locking handle used to lock the follower shaft roller. The main body of the locking handle is made of three sections of plain round or threaded steel bars of different lengths with a diameter greater than 22 mm, which are welded side by side to form a whole as shown in the figure. The total height of the locking handle 20 is about 80 cm, and the lower end touches the ground. As shown in the figure, a sleeve is welded to its bottom. The sleeve is fitted onto the locking handle shaft welded to the corresponding position on the lower part of the enclosure plate 18 for fixing the locking handle. As shown in the figure, the upper end of the locking handle 20 can tilt to the left by about 30 degrees and move away from the rotation range of the locking wheel. As shown in the figure, the locking wheel 8 with multiple notches is installed and fixed to one end of the follower shaft 5 using a keyway method. The protrusion in the middle of the locking handle 20 supports the protrusion at one of the notches of the locking wheel. The arrow pointing to the right in the figure indicates the direction of travel of the engineering vehicle. After the driving wheels of the engineering vehicle are cleaned in this wheel washing machine, it drives away from the wheel washing machine in the direction shown by the arrow in the figure. Its driving wheels exert a force on the protrusion on the outside of the roller provided on the outside of the follower shaft 5 in the opposite direction to the direction shown by the arrow. Because the lower end of the locking handle 20 is pressed against the hard cement ground of the foundation pit, the protrusion in the middle of the locking handle, and the protrusion supporting the notch of the locking wheel upward, the reverse force of the driving wheel on the roller when the engineering vehicle starts is overcome, so that the roller will not rotate in the opposite direction. The roller is stationary relative to the driving wheel, thereby allowing the driving wheel to drive away from the wheel washing machine.

[0042] The above provides a detailed breakdown of each component of the wheel washing machine of the present invention. In cases where there are omissions, those skilled in the art can use similar or close materials and methods to achieve the components and overall functions expressed in the specific embodiments.

[0043] Assemble the components made according to the above instructions into a complete wheel washing machine, install it in the wheel washing machine pit, connect water and electricity, and after debugging, it can carry out the wheel washing work of engineering vehicles bridge (axle) by bridge normally.

[0044] To save materials and costs, the two rollers of this washing machine can be made into segments, with each end of the roller having a raised section on one-third of the way inward, and no roller on the section without the raised section. This not only reduces the seamless steel pipe used for the rollers by about one-third, but also makes daily sludge removal easier. Detailed Implementation Method 2

[0046] The wheel washing machine in the above embodiment is placed naturally in the wheel washing machine pit (above); since the above wheel washing machine does not have a track and wheels and does not have a mobile function, it can be called a fixed wheel washing machine; the defect of the above fixed wheel washing machine is that when the engineering vehicle drives onto the wheel washing machine and stops the wheel to be washed on the drum, the wheel to be washed is not necessarily stopped exactly between the two drums every time. The wheel washing machine requires the wheel to be washed to be stopped between the two drums and simultaneously pressing against the two drums in order to achieve the highest cleaning efficiency; in order to solve the above defects, this embodiment provides a hydraulic mobile wheel washing machine.

[0047] The following is combined Figure 13 This mobile wheel washing machine is described in detail.

[0048] The mobile wheel washing machine in this embodiment is completely identical to the fixed wheel washing machine in the above embodiments in terms of appearance, structure, size, and function of each component. The difference lies in that the mobile wheel washing machine is equipped with a hydraulic cylinder, a track, and wheels or a sliding plate (the mobile model with wheels omits the long strip pad under the left and right side panels compared to the fixed model). Figure 13 This is a schematic diagram of the connection points between the left and right side panels of a wheeled washing machine and the wheels and hydraulic cylinders (the diagram omits other parts of the washing machine and only shows the connection points). As seen in the upper part of the diagram: Wheels 33 are installed at the lower ends of both sides of the left and right side panels 18, and tracks 32 are installed below the wheels, with the tracks set on the bottom surface of the washing machine pit; two hydraulic cylinders 16 are horizontally installed at the upper end of the wheel fixing plates. The piston rod of the left hydraulic cylinder is shown in the diagram as retracted, and its piston rod lug is mounted on a pin-type base welded to the pre-embedded iron surface of the washing machine pit wall. The hydraulic cylinder body... The right-end earring is fitted onto a horizontally positioned columnar pin about 40 cm to the right of the left side of the enclosure panel. The hydraulic cylinder piston rod 17 on the right side of the diagram is shown in its fully extended state. The left-end earring of this hydraulic cylinder 16 is fitted onto a columnar pin about 40 cm to the left of the right side of the enclosure panel. The earring on the right end of the hydraulic cylinder piston rod is fixed to a pin-type base embedded in the iron surface of the right-side washing machine pit wall. The hydraulic cylinder has an inner diameter of approximately 60 mm, a maximum stroke of 300 mm, and a thrust of approximately 7 tons per cylinder. Four hydraulic cylinders are installed on both sides of the enclosure panel, connected to the hydraulic pump via hydraulic oil pipes. The traveling wheels 33 at both ends of the enclosure panel 18 are existing overhead crane traveling wheels. Each traveling wheel has a load capacity of no less than 5 tons, an outer diameter of approximately 150 mm, a groove width of approximately 75 mm, and is fixed by two traveling wheel fixing plates, each approximately 270 mm long and 70 mm wide, with a thicker upper plate and a thinner lower plate, and corresponding mounting holes. The tracks under the traveling wheels are ordinary overhead crane tracks, about 1.3 meters long, and are set on both sides of the bottom of the wheel washing machine pit in the same position and direction as the left and right side panels.

[0049] Another way to move this mobile wheel washing machine is as follows: Unlike the above-mentioned way of moving, the traveling wheels are removed, and a pad with the same width and length as the track and the track panel is welded to the lower part of the left and right side panels to serve as a sliding plate. Anti-derailment devices are set on both sides of the pad downwards, and the pad is placed directly on the track, with the bottom of the pad directly in contact with the track. When needed, the hydraulic cylinder set up above will push the wheel washing machine to slide on the track coated with grease (low-speed engineering machinery lubricant).

[0050] In this embodiment, a corrugated plate is provided on the surface of the roller, such as... Figure 11 and Figure 12 As shown, in Figure 11 The diagram above shows the connection between one end of the roller and the corrugated plate. As can be seen from the diagram, three long, curved corrugated plates are set on the surface of roller 3. The corrugated plates are preferably 1.1 meters long, and their inner surface curvature is in contact with the roller. The material is cast iron, and multiple mounting bolt holes are distributed at multiple protrusions (as shown in the diagram below). Tapered screws are drilled at the corresponding positions on the roller, and the plates are installed and fixed on the roller with hexagonal bolts. The thickness of the corrugated plates is preferably 40 mm at the highest point of the protrusion and preferably 10 mm at the lowest point of the depression. Detailed Implementation Method 3

[0052] To further improve wheel washing efficiency, another way to operate this wheel washing machine is through combined installation. This involves setting up two or more wheel washing machines at a certain distance along the road section inside the construction site exit, so that each wheel of the construction vehicle stops on the rollers of the multiple wheel washing machines simultaneously or separately, and the wheel washing machines are started at the same time or separately, so that all the wheels of the vehicle can be washed in one stop.

[0053] The specific procedure is as follows: Assume a construction site uses Type A and Type B engineering vehicles. Type A vehicles have two axles with a wheelbase of 4 meters. Type B vehicles have four axles with a wheelbase of 1.8 meters + 3.3 meters + 1.4 meters. Based on these vehicle wheelbases, at the site's exit section, five fixed or mobile wheel washing machines are installed laterally, with the rollers roughly flush with the road surface. From the entrance inwards, the center-to-center distance between the first and second wheel washing machines is set to 4 meters (equal to the Type A vehicle's wheelbase), the center-to-center distance between the second and third wheel washing machines is set to 1.8 meters, the center-to-center distance between the third and fourth wheel washing machines is set to 3.3 meters, and the center-to-center distance between the fourth and fifth wheel washing machines is set to 1.4 meters (from the second to the fifth wheel washing machine). The center distance between the wheel washing machines is equal to the wheelbase of the Type B vehicle, and the area between the wheel washing machines is a concrete road surface. With the above setup, when a Type A vehicle arrives, its front wheels will stop between the two rollers of the first wheel washing machine, and its rear wheels will inevitably stop between the two rollers of the second wheel washing machine. The first and second wheel washing machines will be started separately or simultaneously to clean the vehicle. Similarly, when a Type B vehicle arrives, its front wheels will stop between the two rollers of the second wheel washing machine, and its other wheels will inevitably stop between the two rollers of the other wheel washing machines in sequence. Each wheel washing machine will be started separately or simultaneously to clean the vehicle.

[0054] This wheel washing machine can also be used for vehicle cleaning in chemically contaminated areas and epidemic areas. A camera facing the wheel washing machine is installed approximately 1.5 meters above the ground in the direction of oncoming traffic, and connected via wire or wireless connection to a monitor in the control room (area), allowing for visual control of the car wash without on-site personnel. The aforementioned specification lists two rails below the rolling device; however, the use of two or more rails is also within the scope of this invention, as one or more connecting and fixing plates for the front and rear panels can be added between the left and right side panels of the rolling device. These connecting and fixing plates can be used to install pulleys or sliding devices, and their cross-sections can be oriented in a "-=TH" shape or similar. The surface of the roller can have two or more corrugated plates.
