[0036] According to the spraying device provided in the embodiment of the present application, the structure and working principle of the spraying device will be described in detail below with reference to the accompanying drawings.

[0037] According to the spraying device provided in the embodiment of the present application, the spraying device includes a frame 10 and a spraying mechanism. In the embodiment, the frame 10 can reciprocate in a preset section along a first horizontal direction. In the embodiment, the spraying mechanism includes a spraying assembly, and the spraying assembly includes a plurality of nozzles 20. The plurality of nozzles 20 are arranged on the upper side of the frame 10 along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0038] In an embodiment, the size of the frame 10 in the second horizontal direction is smaller than the size of the bus chassis to be sprayed, and the total spray angle of the plurality of nozzles 20 is at least 150 degrees.

[0039] In this way, according to the spraying device provided in the embodiment of the present application, when spraying the bus chassis to be sprayed, the bus can be driven and parked above the spraying device, and then the spraying mechanism in the spraying device can be used to spray the bus chassis to be sprayed from below the bus chassis to be sprayed.

[0040] According to the spraying device provided in the embodiment of the present application, during the spraying process, the frame 10 below the bus chassis to be sprayed reciprocates along the first horizontal direction. Compared with the manual spraying method in the prior art, this spraying method can spray the anti-corrosion wax on the bus chassis to be sprayed in a more uniform manner, thereby avoiding insufficient spraying and missed spraying, and at the same time can also ensure the spraying thickness of the anti-corrosion wax, thereby ensuring the effectiveness of the anti-corrosion wax.

[0041] According to the spraying device provided in the embodiment of the present application, the size of the frame 10 in the second horizontal direction is smaller than the size of the bus chassis to be sprayed, and the total spraying angle of the above-mentioned multiple nozzles 20 is at least 150 degrees. Therefore, the spraying trajectory of the anti-corrosion wax formed by the above-mentioned multiple nozzles 20 is expanded outward at an angle of at least 150 degrees as a whole. This makes it possible to complete the spraying work of the bus chassis to be sprayed by the above-mentioned nozzles 20 even if the size of the frame 10 in the second horizontal direction is smaller than the size of the bus chassis to be sprayed, and the space occupied by the spraying device in the second horizontal direction can be saved.

[0042] According to the spraying device provided in the embodiment of the present application, the spraying device may further include an installation cavity 30, which may be disposed below the frame 10. The spraying device may further include a driving mechanism, which may be used to drive the frame 10 to perform reciprocating motion, and the driving mechanism may be located in the installation cavity 30.

[0043] According to the spraying device provided in the embodiment of the present application, in the embodiment, a collecting chamber 31 located at the bottom of the installing chamber 30 is further provided in the installing chamber 30, and the collecting chamber 31 is used to collect the spraying fluid.

[0044] According to the spraying device provided in the embodiment of the present application, a mounting cavity 30 is provided below the frame 10, and a driving mechanism is provided in the mounting cavity 30, so that the driving mechanism does not occupy external space, thereby facilitating reduction of the space occupied by the spraying device.

[0045] At the same time, since the anti-corrosion wax is sprayed from bottom to top onto the bus chassis to be sprayed, the anti-corrosion wax will inevitably drip downward due to its own gravity. Over time, it is easy to accumulate into a pool and may contaminate the spraying device, thus affecting the life of the spraying device.

[0046] Therefore, according to the spray device provided in the embodiment of the present application, a collecting chamber 31 is further provided at the bottom of the installation chamber 30. For example, the bottom of the installation chamber 30 can be arranged to be inclined toward the collecting chamber 31, so that the dripping anti-corrosion wax can be introduced into the collecting chamber 31 and collected, thereby reusing the installation chamber 30 to increase the service life of the spray device.

[0047] In the embodiment, as an example, the installation cavity 30 may be a trench dug downward from a horizontal surface such as the ground, and the collecting cavity 31 is a cavity further opened at the bottom of the trench to collect dripping anti-corrosion wax.

[0048] According to the spraying device provided in the embodiment of the present application, the spraying device may further include a driving mechanism, which may be used to drive the frame 10 to reciprocate. In the embodiment, the driving mechanism may include a sleeve member 40 and a plurality of wheel members 50, the aforementioned plurality of wheel members 50 are arranged at intervals along the first horizontal direction, the sleeve member 40 may be sleeved on the outside of the plurality of wheel members 50, and is transmission-connected to the plurality of wheel members 50, and the upper side of the sleeve member 40 is connected to the frame 10.

[0049] In an embodiment, by the cooperation of the sleeve member 40 and the plurality of wheel members 50 as described above, the stability of the sleeve member 40 rotating around the aforementioned plurality of wheel members 50 can be ensured, thereby connecting the frame 10 to the sleeve member 40, so that the movement of the frame 10 along the first horizontal direction also has such stability. As an example, in an embodiment, the sleeve member 40 can be, for example, a belt-shaped member, and each wheel member 50 can be driven by a motor 70. As an example, the wheel member 50 can be, for example, a bearing, and the number can be, for example, five, and the driving mechanism can further include motors 70 corresponding to the five wheel members 50. In an embodiment, a groove for accommodating the motor 70 can be provided at the upper edge of the mounting cavity 30 corresponding to each motor 70, and each motor 70 is installed in the groove.

[0050] According to the spraying device provided in the embodiment of the present application, the inner side of the sleeve member 40 and the outer side of each wheel member 50 may be provided with a tooth structure, and the tooth structure on the inner side of the sleeve member 40 and the tooth structure on the outer side of the wheel member 50 are meshed with each other. In the embodiment, through such meshing tooth structures, the movement speed of the sleeve member 40, that is, the movement speed of the frame 10 can be accurately controlled, so as to facilitate providing uniform spraying. As an example, in the embodiment, the sleeve member 40 can be, for example, a crawler, and the wheel member 50 with a tooth structure can essentially be a bearing with a tooth structure provided on the outer side of the outer ring.

[0051] According to the spraying device provided in the embodiment of the present application, the driving mechanism may further include a plurality of support members 60, the support members 60 may be connected to the upper side of the sleeve member 40, and the support members 60 may extend downward from the outer side of the sleeve member 40 in the vertical direction. As an example, in the embodiment, the support member 60 may be formed by connecting two plates, wherein the plate connected to the upper side of the sleeve member 40 may be, for example, a horizontal plate, and the plate extending downward from the outer side of the sleeve member 40 in the vertical direction may be, for example, a vertical plate, and the two plates are perpendicular to each other.

[0052] In the embodiment, the function of the support member 60 is that when there is a certain droop in the portion of the sleeve member 40 serving as the track between the two wheel members 50, the vertical plate of the support member 60 supports this portion of the track, thereby ensuring the stability of the track.

[0053] According to the spraying device provided in the embodiment of the present application, the spraying device may further include a support surface disposed below the support member 60, and the support surface may be used to abut against the support member 60. In the embodiment, after the support surface abuts against the vertical plate of the support member 60, it can prevent the support member 60 from further moving downward, thereby avoiding the collapse of the crawler track.

[0054] In an embodiment, as an example, the support surface can be, for example, the bottom surface of a groove portion that accommodates the motor 70. In this way, on the one hand, the groove surface of the groove portion is fully utilized, saving the space occupied by the components that may originally be provided to provide the support surface. On the other hand, the vertical plate of the support member 60 falls into the groove portion when it descends, thereby supporting the support member 60 while making the structure of the spray device more compact and occupying less space.

[0055] In the embodiment, as an example, the crawler and the corresponding wheel member 50 and the motor 70 can be arranged in two groups along the second horizontal direction. Correspondingly, the groove portion can also be arranged in two groups. In the embodiment, as described above, in each group, the number of the motor 70 can be, for example, five, and the number of the groove portion and the support member 60 can also be, for example, five.

[0056] According to the spraying device provided in the embodiment of the present application, the multiple nozzles 20 as above are connected in parallel, which can ensure that the pressure of the anti-corrosion wax in the multiple nozzles 20 is approximately the same, thereby ensuring the uniformity of the anti-corrosion wax sprayed by different nozzles 20.

[0057] In addition, according to the spraying device provided in the embodiment of the present application, the spray angle range of each nozzle 20 can be 60-70 degrees. In the embodiment, if the spray angle range of each nozzle 20 is too low, it may cause the anti-corrosion wax to be incompletely covered. If the spray angle range of each nozzle 20 is too large, the overlap width of the spray bands of the anti-corrosion wax sprayed by adjacent nozzles is difficult to control, and it is easy to cause the overlap width to be too large. The range of the spray angle can be, for example, 60 degrees, 62 degrees, 64 degrees, 66 degrees or 68 degrees.

[0058] According to the spraying device provided in the embodiment of the present application, adjacent nozzles 20 of the spraying device are arranged so that the overlapping width of adjacent spraying bands formed by the adjacent nozzles 20 spraying onto the bus chassis is 50-100 mm.

[0059] According to the spraying device provided in the embodiment of the present application, when the overlap width is too small, it is not easy to ensure that the anti-corrosion wax is evenly sprayed. When the overlap width is too large, the overlap band is thicker and occupies a larger area, which is not conducive to the even spraying of the anti-corrosion wax.

[0060] In addition, according to the spraying device provided in the embodiment of the present application, the distance between the frame 10 and the bus chassis to be sprayed can be, for example, 300-360 mm, and the movement speed of the frame 10 can be configured to be at most 4 m / min to ensure the uniformity of the anti-corrosion wax sprayed by the spraying device. According to the spraying device provided in the embodiment of the present application, the spraying mechanism also includes a sprayer and a pipeline, the pipeline connects the sprayer and the multiple nozzles 20 to provide anti-corrosion wax to the multiple nozzles 20, and part of the pipeline is arranged in the installation cavity 30. For example, a multi-circle winding pipeline can be arranged in the installation cavity 30 to provide the pipeline with a margin for follow-up when the frame 10 reciprocates. In the embodiment, the pipeline can be connected to the wax sprayer 80 on the ground through an underground pre-buried pipe, and the wax sprayer 80 provides the pipeline and the nozzle 20 with anti-corrosion wax with a certain pressure.

[0061] According to the spraying device provided by the present application, a trench can be built as an installation cavity, 5 drive motors are arranged on the left side of the trench, and 5 drive motors are arranged on the right side. The motors can be fixed using M8*40 hexagonal bolts, and all motors are fixed on the same plane.

[0062] In the embodiment, a 300mm diameter toothed bearing is installed on the shaft of the motor as a wheel member. A crawler is installed above the bearing to drive the mobile frame assembly forward and backward. The mobile frame assembly is installed above the crawler. The mobile frame assembly is welded with 10*30 galvanized square pipes, and a galvanized sheet is welded on top. The surface of the galvanized sheet is opened for installing fan-shaped nozzles. The arrangement principle of the fan-shaped nozzles is to arrange a right-angle fan-shaped nozzle in the middle, with a total of 3 pieces, and arrange a curved fan-shaped nozzle at both ends, with a total of 2 pieces, so as to form a total of 5 nozzles.

[0063] In the embodiment, the wax spray pipeline can be led out from the wax spray machine cabinet, introduced into the trench through the trench casing, and a sufficiently long pipeline is reserved under the trench. The four-way quick plug is connected to the middle right-angle fan-shaped nozzle interface, and the joints on both sides of the four-way quick plug are inserted into the wax spray pipe, which is directly connected to the three-way quick plugs on both sides. Both ends of the three-way quick plug are connected to the right-angle fan-shaped nozzle and the curved fan-shaped nozzle to form a parallel structure.

[0064] In the embodiment, an L-shaped bracket is installed on the edge of the mobile frame assembly and fixed with an M8*40 hexagonal bolt. The top of the bracket is fixed with an M8*40 hexagonal bolt in combination with a clamp to fix the pipeline. An L-shaped support baffle is installed between each drive motor, i.e., a support member, 5 pieces on the left and 5 pieces on the right, a total of 10 pieces. During the installation process, ensure that the mounting surface and the drive bearing are on the same plane, ensure that the crawler falls exactly on the plane, and play a role in supporting the crawler. The L-shaped support baffle is fixed with an M8*40 hexagonal bolt.

[0065] In an embodiment, an L-shaped collision limit bracket can also be installed on both sides of the trench and fixed with M8*40 hexagonal bolts, and a limit collision block can be installed above the bracket. The collision block can be, for example, rubber limit collision blocks can be installed on both sides of the mobile rack assembly facing the rack to abut and limit the L-shaped collision limit bracket.
