Abstract
Description
Technical Field
[0001] The utility model relates to a car washing device, belonging to the technical field of car washing equipment. Background Art
[0002] Mobile contactless automatic car washes have the advantages of flexible layout, fast car washing speed, and no damage to the vehicle surface. The contactless car wash machine uses a car washing device equipped with a car washing arm to surround the vehicle and spray high-pressure cleaning water on the vehicle for cleaning. In addition to installing a car washing arm that sprays high-pressure water on the vehicle, the car washing device also needs to be installed with a walking mechanism to ensure that the car washing device can stably drive the car washing arm to repeatedly circle the vehicle along the car washing guide rail to complete the cleaning of the vehicle. The walking mechanism of the existing car washing device is usually equipped with two linear guide rails along the longitudinal direction of the vehicle, and two sets of drive wheels are provided to push the car washing device forward or backward synchronously on the corresponding guide rails. The drive structure is relatively complex, and in actual operation, the two sets of drive wheels often cannot move synchronously, causing the car washing arm to move in a biased direction or even touch the vehicle and damage the car paint.
[0003] Therefore, there is an urgent need for a car washing device with simple structure, stable movement and good safety. Summary of the Invention
[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a car washing device with simple structure, stable movement and good safety.
[0005] The purpose of this utility model is achieved in this way:
[0006] A car washing device comprises two guide rails arranged parallel to the longitudinal direction of a vehicle, a washing platform slidably arranged between the guide rails, a washing arm group and a walking mechanism are installed on the washing platform, the walking mechanism comprises a walking motor arranged in the middle of the washing platform, and several sets of driving wheel groups arranged at both ends of the washing platform; the driving wheel group comprises two rollers symmetrically arranged at both ends of the washing platform; the two rollers of the driving wheel group are synchronously connected to the walking motor through several couplings and a transmission shaft.
[0007] Furthermore, at least two sets of driving wheel assemblies are arranged in parallel on the cleaning platform.
[0008] Furthermore, the transmission shafts of adjacent driving wheel sets are synchronously connected through sprockets and chains.
[0009] Furthermore, the cleaning arm group includes two sets of symmetrically arranged butterfly robotic arms, and nozzles for spraying high-pressure water inward are evenly distributed on the butterfly robotic arms.
[0010] Furthermore, the cleaning platform is provided with a plurality of bottom nozzles for spraying foam or water wax.
[0011] Furthermore, a radar rangefinder for measuring the height of the vehicle is provided on the cleaning platform.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] The utility model realizes synchronous rotation by arranging a coupling and a transmission shaft between the rollers of the driving wheel group of the cleaning platform, and arranges multiple sets of driving wheel groups that are synchronously transmitted to each other, thereby ensuring the synchronization of the rotation of the rollers on both sides of the cleaning platform, ensuring that the cleaning platform does not deviate in translation, improving the stability and safety of the cleaning platform translation, and preventing the car washing arm from rubbing against the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 The utility model is a structural schematic diagram of a car washing device.
[0015] Figure 2 This is a top view of a cleaning platform of a car washing device according to the present invention.
[0016] in:
[0017] Cleaning platform 1, walking motor 2, roller 3, coupling 4, transmission shaft 5, guide rail 6, sprocket 7, chain 8, butterfly robotic arm 9, nozzle 10, bottom nozzle 11, radar rangefinder 12. DETAILED DESCRIPTION
[0018] See also Figure 1~Figure 2 The utility model relates to a car washing device, comprising two guide rails 6 arranged parallel to the longitudinal direction of the vehicle, a washing platform 1 slidably arranged between the guide rails 6, and a plurality of bottom nozzles 11 for spraying foam or water wax, a radar rangefinder 12 for measuring the height of the vehicle, a washing arm group and a walking mechanism. The bottom nozzles 11 spray foam or water wax to the vehicle to meet the multi-functional car washing needs. The radar rangefinder 12 detects the specific position of the head and tail of the vehicle, which facilitates the walking mechanism to determine the end limit of the forward and backward movement.
[0019] The cleaning arm group includes two sets of symmetrically arranged butterfly mechanical arms 9, and nozzles 10 for spraying high-pressure water inward are evenly distributed on the butterfly mechanical arms 9; the nozzles 10 of the two sets of butterfly mechanical arms 9 cover the roof and both sides of the vehicle, and wash the vehicle with high-pressure water;
[0020] The walking mechanism includes a walking motor 2 arranged in the middle of the cleaning platform 1 and several sets of driving wheel groups arranged at both ends of the cleaning platform 1. In this embodiment, three sets of driving wheel groups are arranged in parallel on the cleaning platform 1;
[0021] Each set of driving wheel groups includes two rollers 3 symmetrically mounted at both ends of the cleaning platform 1, and the rollers 3 are rollingly arranged on the guide rails 6. The two rollers 3 of the driving wheel group are synchronously connected to the travel motor 2 through a number of couplings 4 and a transmission shaft 5. The travel motor 2 drives the two rollers 3 of the driving wheel group to rotate forward or backward synchronously, thereby pushing the cleaning platform 1 forward or backward along the guide rails 6. This prevents the rotation speed deviation of the two rollers 3 from causing the cleaning platform 1 to shift in the right direction and cause accidents, thereby improving the safety of the car washing operation.
[0022] The transmission shafts 5 of adjacent driving wheel groups are connected by sprockets 7 and chains 8 for synchronous transmission. In other embodiments, the sprockets 7 and chains 8 can be replaced with synchronous belt transmissions. Since the six rollers 3 of the three driving wheel groups are all driven by the same travel motor 2 to rotate synchronously in the same direction, it can prevent some rollers 3 from slipping, which causes inconsistent translation speeds on both sides of the cleaning platform 1 and causes translation deviation, further ensuring the consistency of the translation speeds on both sides of the cleaning platform 1 and improving the stability and safety of the car washing operation.
[0023] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
