DETAILED DESCRIPTION

[0019] In the following text, only certain exemplary embodiments are simply described. As those skilled in the art can realize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0020] The embodiments of the present application are described in detail below in combination with the drawings.

[0021] As Figures 1-6 shown, the new conveyor of the full-automatic car washer provided by the embodiments of the present application is composed of a guider 10 and a conveyor frame 20, the guider 10 is fixedly installed on the car-entering end side of the conveyor frame 20, the two are rigidly connected through a welded metal connecting frame, the weld joint at the connection is made by full welding process, the load-bearing stability of the whole structure is ensured, the load-bearing requirement of different vehicle models such as family cars and SUVs is met, the core role of the guider 10 is to complete the automatic guiding before the vehicle enters the position and the wheel dredging, the conveyor frame 20 bears the stable conveying, safe locking and data monitoring functions of the vehicle, and the two realize the full automation of the car washing conveying link in cooperation.

[0022] The guide corrector 10 is a frame structure, the overall frame is bent and welded by a stainless steel plate with a thickness of 5 mm, the guide corrector 10 is suitable for the track and body width of most domestic vehicles, and the guide corrector 10 is internally integrated with a guide corrector anti-collision wheel 11, a guide corrector roller 12, a dredging grid 13 and a guide corrector positioning roller 14.

[0023] In one embodiment, the guide corrector anti-collision wheel 11 is a rubber wheel body, which is made of wear-resistant rubber with a Shore hardness of 60HA, and has sufficient elasticity to buffer the lateral collision when the vehicle is positioned, and can ensure the wear resistance of the wheel body to avoid frequent replacement. The guide corrector anti-collision wheel 11 is symmetrically installed at both ends of the guide corrector positioning roller 14, and each guide corrector positioning roller 14 is provided with one guide corrector anti-collision wheel 11 at each end, and the whole machine has four guide corrector anti-collision wheels 11. The guide corrector anti-collision wheel 11 is connected to the top frame of the guide corrector 10 through a rotating shaft, the rotating shaft is made of 45 carbon steel with a diameter of 12 mm to ensure the connection strength. When the vehicle is positioned and slightly deviated, the wheel will first contact the guide corrector anti-collision wheel 11, and the elastic deformation of the wheel body can offset the impact force to avoid direct scratching of the vehicle and the metal frame, and guide the wheel to return to the preset path. The guide corrector roller 12 is a metal roller, the base body of which is made of 304 stainless steel, and the outer surface of the guide corrector roller 12 is wrapped with a wear-resistant rubber layer with a thickness of 4 mm. The rubber layer here is made of nitrile rubber with a Shore hardness of 65HA, which has the advantages of resistance to mud and sand wear and excellent anti-skid performance, which can reduce the slipping phenomenon between the wheel and the guide corrector roller 12. The guide corrector roller 12 is arranged along the length direction of the dredging grid 13, which can not only ensure the continuous support of the wheel, but also avoid the accumulation of mud and sand caused by high roller density. The two ends of the guide corrector roller 12 are connected to the inner frame of the guide corrector 10 through a micro deep groove ball bearing, which can realize flexible rotation of the roller and reduce the resistance when the wheel passes through, thereby assisting the vehicle to move smoothly. The dredging grid 13 is a hollow grid structure, which is a plate-shaped member made of 304 stainless steel and completely matches the internal installation space of the guide corrector 10. The hollow grid on the grid is a square structure, which can smoothly scrape off the impurities such as mud and small stones in the tire tread, and will not cause wheel jamming due to too large grid. The dredging grid 13 is detachably installed on the bottom frame of the guide corrector 10 through bolts, and the detachable design facilitates the cleaning of the mud accumulated below the dredging grid 13 in the later stage. When the vehicle wheel passes through the dredging grid 13, the impurities in the tread will be scraped off by the edge of the grid and fall into the mud collecting tank below the dredging grid 13, realizing the preliminary dredging of the wheel and avoiding the mud entering the subsequent conveying area. The length of the guider positioning roller 14 is matched with the width of the guider 10, the base thereof is made of stainless steel, and the outer surface is also wrapped with a 4mm-thick wear-resistant rubber layer. The guider positioning roller 14 is symmetrically arranged on the top frame of the guider 10, and two groups of guider positioning rollers 14 are arranged in total. The center distance between the two groups of guider positioning rollers 14 is matched with the front wheel track of the household vehicle, so as to accurately limit the front wheel of the vehicle. The two ends of the guider positioning roller 14 are connected with the frame of the guider 10 through bearing seats. The bearing seats are made of stamping carbon steel bearing seats, and the bearing capacity thereof is sufficient to support the weight of the front wheel of the vehicle. When the vehicle enters the guider 10, the guider roller 12 first preliminarily guides the vehicle wheel, and then the guider positioning roller 14 limits the front wheel in the transverse direction, so as to force the vehicle wheel to enter the conveying frame 20 along a path parallel to the conveying direction, thereby completely replacing manual guidance and avoiding positioning deviation.

[0024] The conveying frame 20 is a whole type load-bearing frame, the frame of which is welded by using No. 8 channel steel, so as to provide sufficient bending strength, and ensure that the frame does not deform when bearing the vehicle. The overall size of the conveying frame 20 is matched with the conventional layout of the car washing station. The conveying frame 20 is integrated with basic support and leveling components, inlet adaptation and buffer components, conveying transmission components, anti-skid and protection components, driving and tensioning components and end safety and sensing components.

[0025] In an embodiment, the basic support and leveling components include fixed support rods 24, adjustable support rods 28 and ground grid support bars 29. The fixed support rod 24 is a cylindrical rod body, the material of which is selected from plain carbon structural steel. The steel has moderate strength, good toughness and controllable cost, and is suitable for being used as an auxiliary support of the conveying frame 20. The fixed support rod 24 is equidistantly distributed along the length direction of the conveying frame 20, so as to ensure the transverse stability of the conveying frame 20, and avoid the overturning of the conveying frame 20 due to the rolling of the vehicle. One end of the fixed support rod 24 is welded with the outer side wall of the conveying frame 20, and the other end is welded with a steel plate pre-buried in the ground, so as to realize the fixed installation of the conveying frame 20, and prevent the displacement of the conveying frame 20 during conveying. The adjustable support rod 28 is equidistantly distributed along the bottom of the conveying frame 20, and is used for adjusting the horizontal height of the conveying frame 20 to adapt to uneven ground. The adjustable support rod 28 is composed of an outer rod, an inner rod and a support foot pad. The outer rod is welded with the bottom of the conveying frame 20. The inner rod is threadedly connected with the outer rod, so as to realize the slight adjustment of the height of the frame. The inner rod is fixed with a circular rubber support foot pad at the bottom. The rubber material has a Shore hardness of 70HA, which can increase the friction with the ground to prevent slipping, and also can buffer the vibration of the conveying frame 20 during operation. The ground grid support 29 is installed on the inner wall of the conveying frame 20 on both sides, and two are arranged on each side. The ground grid support 29 is an L-shaped metal strip made of stainless steel. One end of the ground grid support 29 is fixed to the inner wall of the conveying frame 20 by a bolt, and the other end extends to the center of the conveying frame 20. An auxiliary grid plate can be arranged on the top of the conveying frame 20. The ground grid support 29 supports the auxiliary grid plate arranged on the top of the conveying frame 20, prevents the auxiliary grid plate from collapsing due to vehicle rolling, and provides a sliding channel for the mud and sand, thereby reducing the accumulation of impurities in the conveying area. The entrance adapter and buffer component includes a conveyor pedal 22, a conveyor pedal spring 21, a conveyor entrance chain wheel 23, a conveyor entrance adjustable module 26, and an adjustable tightening spring 27. The conveyor pedal 22 is installed on one side of the conveying frame 20 close to the conveyor entrance chain wheel 23. The surface is treated to prevent slipping. Two conveyor pedal springs 21 are symmetrically arranged on the bottom of the conveyor pedal 22. The conveyor pedal spring 21 is a cylindrical spiral spring that can withstand the pressure of the vehicle wheel for a long time without plastic deformation. One end of the conveyor pedal spring 21 is welded to the bottom of the conveyor pedal 22, and the other end is welded to the top of the conveying frame 20. When the vehicle wheel presses on the conveyor pedal 22, the conveyor pedal spring 21 will elastically deform, causing the conveyor pedal 22 to slightly sink. This can adapt to different diameters of vehicle wheels and improve the smoothness of vehicle positioning. The conveyor entrance chain wheel 23 is installed on the inside of the vehicle entry end of the conveying frame 20. It is a single-row roller chain wheel that adapts to the subsequent high-strength conveyor chain 32. The wheel shaft of the conveyor entrance chain wheel 23 is connected to the conveying frame 20 through a bearing support 33 to ensure the flexible rotation of the conveyor entrance chain wheel 23. The conveyor entrance adjustable module 26 is installed on one side of the conveying frame 20 close to the conveyor entrance chain wheel 23. Its function is to adjust the entrance width to adapt to vehicles with different wheelbases. This module consists of an adjusting frame, an adjusting slider, and a locking bolt. The adjusting frame is fixed to the side wall of the frame by a bolt. The adjusting slider can freely slide in the adjusting frame. The locking bolt is arranged along the length direction of the adjusting slider and is used to lock the adjusting slider in a specified position of the adjusting frame to prevent the slider from shifting when the vehicle passes. An adjustable tightening spring 27 is fixedly installed on one side of the adjusting slider. The spring is a cylindrical spiral compression spring. The other end of the adjustable tightening spring 27 is welded to the side wall of the conveying frame 20. Its functions are as follows: first, it provides a pre-tightening force for the adjusting slider to ensure that the slider does not move when the locking bolt is loose; second, it buffers the rigid contact between the wheel and the slider. When the wheel presses the slider, the spring can slightly deform to achieve self-adaptive fine adjustment of the entrance width, further improving the adaptability of vehicle positioning. In actual application, the entrance width can be adjusted by sliding the adjusting slider to the appropriate position and tightening the locking bolt according to the wheelbase of the vehicle to be conveyed. The conveying transmission component includes a conveying high-strength chain 32, a conveying push rod roller 31, a bearing support 33, and a conveying outlet sprocket 42: The conveying high-strength chain 32 is sleeved on the outside of the conveying inlet sprocket 23 and the conveying outlet sprocket 42, is a stainless steel roller chain, and has a single row arrangement. The stainless steel material can prevent the conveying high-strength chain 32 from rusting due to water vapor erosion in a car washing scene, thereby prolonging the service life. The conveying push rod roller 31 is arranged along the extension direction of the conveying high-strength chain 32. The conveying push rod roller 31 is a metal roller, and the outer surface is wrapped with a 7mm-thick wear-resistant rubber layer. The conveying push rod roller 31 is welded to the outer chain plate of the conveying high-strength chain 32 by using a bevel welding process to ensure the connection strength. When the conveying high-strength chain 32 operates, the conveying push rod roller 31 moves synchronously. The top of the conveying push rod roller 31 protrudes from the bearing surface of the conveying frame 20, so that the conveying push rod roller 31 can effectively push the wheels to move forward and realize stable conveying of the vehicle. The bearing support 33 is installed on the inner bottom of the conveying frame 20 and is used for supporting the wheel shafts of the conveying inlet sprocket 23 and the conveying outlet sprocket 42. The bearing support 33 is composed of a support arm and a bearing seat. The support arm is a rectangular metal plate, and the bottom is installed on the inner bottom of the conveying frame 20 by using bolts. The bearing seat is fixed to the top of the support arm and is a split carbon steel bearing seat. A deep groove ball bearing is installed in the bearing seat. The inner ring of the bearing is matched with the wheel shaft of the sprocket, so that the wheel shaft can rotate with low resistance and ensure the stability of transmission. The conveying outlet sprocket 42 is installed on the inner side of the vehicle outlet end of the conveying frame 20. The structure of the conveying outlet sprocket 42 is consistent with that of the conveying inlet sprocket 23. The conveying outlet sprocket 42 is meshed with the conveying high-strength chain 32 to form a transmission. As a driven sprocket of the chain, the conveying outlet sprocket 42 cooperates with the conveying motor 39 at the driving end to realize the circulation of the chain. The anti-skid and protection component includes an anti-skid strip 25 and an outlet motor protection cover 41. The anti-skid strip 25 is symmetrically installed on the top of the conveying frame 20. The anti-skid strip 25 is made of hard rubber and has a trapezoidal cross section. The length of a single anti-skid strip 25 is matched with the width of the top of the conveying frame 20. The anti-skid strip 25 is bonded to the top of the conveying frame 20 by using strong glue. The anti-skid strip 25 can increase the friction between the wheels and the bearing surface of the conveying frame 20, prevent the vehicle from slipping laterally during conveying, and further improve the conveying stability. The outlet motor protection cover 41 is installed on the top of the conveyor motor 39. It is a rectangular cover made of sheet metal, with six circular heat dissipation holes with a diameter of 20mm on the side wall. The heat dissipation holes are arranged in a matrix to ensure heat dissipation during the operation of the conveyor motor 39 and prevent water from splashing into the interior of the conveyor motor 39 during car washing. The outlet motor protection cover 41 is fixed on the top of the motor support plate 38 by bolts. The cover is made of 304 stainless steel, which has excellent rust resistance and is suitable for the humid environment of the car washing scene. The driving and tensioning components include a motor support plate 38, a conveyor motor 39, and a motor adjusting device 35. The motor support plate 38 is a steel rectangular plate welded to one side of the conveyor frame 20. The welding is done using a double-sided welding process to ensure load-bearing capacity and stable support for the weight of the conveyor motor 39. The surface of the motor support plate 38 is provided with a waist-shaped mounting hole to facilitate the adjustment of the installation position of the motor and achieve the tensioning of the transmission chain. The conveyor motor 39 is a three-phase asynchronous reduction motor with low-speed and high-torque output characteristics to meet the power requirements of vehicle transportation while avoiding safety hazards caused by excessive vehicle speed. The conveyor motor 39 is fixed in the waist-shaped hole of the motor support plate 38 by bolts. Its output shaft is connected to the wheel shaft of the conveyor outlet sprocket 42 through the conveyor high-strength chain 32 to provide power for the entire conveying system. The motor adjusting device 35 is installed at the bottom of the conveyor frame 20 and consists of an adjusting seat and an adjusting screw. The adjusting seat is a stainless steel plate with a thickness of 8mm and is fixed to the bottom of the frame by bolts. One end of the adjusting screw is threaded into the adjusting seat, and the other end faces the base of the conveyor motor 39. When the conveyor high-strength chain 32 becomes loose, the adjusting screw can be rotated to push the motor base along the waist-shaped hole, thereby achieving the tensioning of the transmission chain, ensuring transmission efficiency, and preventing chain skipping. The end safety and sensing components include an outlet anti-slip device 37, a sensor protection cover 34, a weighing sensor, and an outlet counting disc 36. The outlet anti-slip device 37 is installed on one side of the conveyor frame 20 near the conveyor outlet sprocket 42. It consists of a lifting pawl and an anti-slip pedal. The lifting pawl is an L-shaped metal structure with a rotating shaft at one end. The rotating shaft is installed inside the conveyor frame 20 through a bearing seat to achieve the lifting and rotation of the pawl. The anti-slip pedal is a plate-shaped structure with a wear-resistant rubber layer on a metal base plate. One end of the anti-slip pedal is hinged to the top of the conveyor frame 20 through a hinge shaft. When the vehicle is transported to the end, the wheels will press down the anti-slip pedal, driving the lifting pawl to rise through a linkage mechanism. The pawl will be clamped between the tire grooves of the wheels, completely avoiding the safety hazard of vehicle slipping. After the vehicle leaves, the pawl falls back under the action of the return spring, restoring the initial state. The sensor protection cover 34 is a sealed cover body made of stainless steel, which is fixed on one side of the conveyor frame 20 by bolts. Its function is to protect the internal sensing elements from water vapor and silt erosion. The inner wall top of the protection cover is fixed with a weighing sensor through an L-shaped support. The inner wall side is fixed with an outlet counting disc 36 through bolts. The L-shaped support is made of stainless steel, which can stably support the sensing elements. The weighing sensor is a resistance strain sensor, which can accurately monitor whether the vehicle wheel is pressed on the conveyor pedal 22, and realize the detection of the vehicle entry state. The probe of the weighing sensor is installed on the bottom of the conveyor pedal spring 21 through a fixing seat. When the vehicle wheel presses down the pedal, the deformation amount of the spring will be transmitted to the probe. The sensor converts the pressure signal into an electrical signal and feeds back to the control system of the car washing station. The outlet counting disc 36 is a photoelectric counting disc, and its sensing end faces the outlet direction of the conveyor frame 20. The resolution of the counting disc is 100 pulses / revolution. When the vehicle drives away from the conveyor frame 20, the wheel will drive the sensing sheet of the counting disc to rotate, and the counting disc will generate a pulse signal to realize the accurate statistics of the number of conveyed vehicles. The statistical data can be transmitted to the control system to provide data support for the process connection and process scheduling of the car washing station.
