Detailed Description
The utility model is described in further detail below with reference to the drawings and examples, which are not intended to be limiting.
Referring to fig. 1-4, a conformal water spraying device of an automatic car washer is arranged on a portal frame 6 of the car washer and comprises a water spraying pipe assembly 2, a supporting wheel 1 and a driving mechanism 3.
The spray pipe assembly 2 is provided with a support shaft 201, a water outlet pipe 203 and a connecting rod 202 for connecting the support shaft 201 and the water outlet pipe 203, wherein the support shaft 201 is in matched connection with a bearing 4 arranged on a portal frame 6, and the support shaft 201 is horizontally arranged; one end of the connecting rod 202 is welded with the midpoint position of the supporting shaft 201 in the length direction, the other end of the connecting rod is welded with the midpoint position of the water outlet pipe 203 in the length direction, and the water outlet pipe 203 is parallel to the supporting shaft 201; two supporting wheels 1 with the same radius are installed on the water outlet pipe 203, an opening type fixing ring 5 installed on the water outlet pipe 203 is arranged on two sides of the supporting wheels 1 respectively to limit the axial direction of the supporting wheels 1, the distance between the two opening type fixing rings 5 is larger than the axial thickness of the supporting wheels 1, the supporting wheels 1 are prevented from being locked, free rotation of the supporting wheels 1 on the water outlet pipe 203 is guaranteed, the cavity inside the water outlet pipe 203 is connected with an external water source through a hose, and a plurality of nozzles 204 are arranged on the water outlet pipe 203 along the length interval of the water outlet pipe.
Furthermore, the outer layer of the supporting wheel 1 is made of soft materials so as to avoid scratching the vehicle body.
In this embodiment, two supporting wheels 1 are installed on the water outlet pipe, and in practice, one or more than two supporting wheels 1 may be installed on the water outlet pipe 203, where when one supporting wheel 1 is provided, the supporting wheel 1 should have a larger width, so as to ensure that the water outlet pipe 203 does not shake substantially left and right during the car washing process; when a plurality of supporting wheels 1 are provided, the supporting wheels 1 may be symmetrically arranged with respect to the connecting rod 202, and the supporting wheels 1 may have the same radius, so that the water outlet pipe 203 may be maintained horizontal, and a closer water spraying distance from each nozzle 204 to the vehicle body may be ensured. In order to ensure the short-distance water spraying cleaning effect, the radius of the supporting wheel 1 is set to be 10-30cm.
As shown in fig. 3, the driving mechanism 3 includes an air cylinder 301, a Y-joint 302, and a swing arm 303. The cylinder body of the cylinder 301 is rotatably connected with a hinge seat at the upper part of the portal frame 6, and the rotation axis is parallel to the support shaft; one end of the Y-shaped joint 302 is in threaded connection with a piston rod of the air cylinder 301, and a fork head at the other end is in rotary connection with the swing arm 303 through a pin shaft; one end of the swing arm 303 is a small end, the other end is a large end, the small end is rotatably connected with the Y-shaped joint 302, and the large end is fixedly connected with the supporting shaft 201. Along with the expansion and contraction of the piston rod of the air cylinder 301, the swing arm 303 is driven to swing, and then the supporting shaft 201 is driven to rotate by taking the bearing 4 as a fulcrum, so as to lift the water outlet pipe 203 or drop the water outlet pipe 203. As shown in fig. 2 and 3, when the piston rod of the cylinder 301 is fully extended, the water outlet pipe 203 is at the lowest position, and when the piston rod is fully retracted, the water outlet pipe 203 is at the highest position.
The air inlet pipeline and the air outlet pipeline of the cylinder 301 are both connected to one reversing valve, and the rod cavity and the rodless cavity of the cylinder 301 are communicated with the outside atmosphere through branches through switching of the reversing valve, so that the piston rod can freely move back and forth under the action of external force. The reversing valve is two-position five-way or three-position five-way.
When washing, the piston rod of the air cylinder 301 is extended to control the water outlet pipe 203 to fall to the low position firstly, then the air valve is opened, the air cylinder is not powered any more, the piston rod is in a free state, the water outlet pipe 203 is kept in a free and flexible state under the action of gravity, when the portal frame 6 moves, the vehicle body is in contact with the supporting wheel 1 and gradually jacks up the supporting wheel 1, and the supporting wheel 1 and the vehicle body are always in contact and follow the outline shape of the vehicle regardless of the change of the vehicle type. If the radius of the supporting wheel 1 is about 20cm, the distance between the nozzle 204 on the water outlet pipe 203 and the vehicle body is always about 20cm, and the short-distance high-pressure flushing effect is better. After the water spraying is finished, the piston rod of the air cylinder 301 is contracted, the water outlet pipe 203 is lifted, the vehicle is separated from the vehicle body, and the vehicle can be driven out of the car washer.
When the device is specifically implemented, the device can be matched with a conventional 7-shaped water spray pipe to be used, so that all parts of a vehicle body are ensured to be cleaned.
Further, as shown in fig. 4, the shape-following water spraying devices of the present utility model are arranged in two sets, and are arranged back and forth, the water outlet pipe 203 can be lifted up and separated from the vehicle body when swinging to the outside of the portal frame 6, and can be dropped down to make the supporting wheel 1 contact with the vehicle body when swinging to the inside of the portal frame 6. As shown in fig. 5, when the two sets of devices are used for washing vehicles, when the portal frame 6 moves leftwards, the water outlet pipe 203 of the left device is lifted, and the water outlet pipe 203 of the right device falls down to wash the vehicle head; on the contrary, when the portal frame 6 moves rightwards, the water outlet pipe 203 of the right device is lifted, and the water outlet pipe 203 of the left device falls down to the tail of the cleaning vehicle.
The above embodiments are only for illustrating the technical solution of the present utility model and not for limiting it, and it should be understood by those skilled in the art that modifications and equivalents may be made to the specific embodiments of the present utility model with reference to the above embodiments, and any modifications and equivalents not departing from the spirit and scope of the present utility model are within the scope of the claims appended hereto.
