[0037] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0038] Example 1

[0039] A cleaning device for cleaning a tank truck, such as Figure 1 As shown, a cleaning arm 100 and a Z-axis moving mechanism 200 for driving the cleaning arm 100 to extend and retract so as to enter or exit the interior of the tanker 600 are provided, and the cleaning arm 100 can be telescopically assembled on the Z-axis moving mechanism 200 .

[0040] The Z-axis moving mechanism 200 is provided with a first assembly frame 210, a first driving part 220 for driving the first assembly frame 210 and the cleaning arm 100 to move along the Z axis as a whole, and a transmission assembly 230 for driving the cleaning arm 100 to move along the Z axis. The driving end of the first driving part 220 is fixedly assembled with the first assembly frame 210, the transmission assembly 230 is fixedly assembled with the first assembly frame 210, and the transmission assembly 230 is fixedly assembled with the cleaning arm 100. The cleaning arm 100 is located inside the first assembly frame 210 and can move through the first assembly frame 210. Figure 2 shown.

[0041] The transmission assembly 230 is provided with a first driven wheel 231, a second driven wheel 232 and a chain 233. The first driven wheel 231 and the second driven wheel 232 are respectively mounted on the upper and lower ends of the first assembly frame 210, and the chain 233 is respectively meshed and connected with the first driven wheel 231 and the second driven wheel 232, and the chain 233 is also fixedly connected with the first assembly frame 210 and the washing arm 100 through a fixing block 234. The moving distance of the primary movement is equal to the moving distance of the secondary movement; when the washing arm 100 is retracted, the washing arm 100 is stored in the interior of the first assembly frame 210 as a whole, as shown in FIG. Figure 3 shown.

[0042] It should be noted that the Z-axis moving mechanism 200 of the utility model uses the first driving part 220 as a single power source to drive the first assembly frame 210 to move up and down along the Z-axis to generate a primary motion. When the first assembly frame 210 moves, because the chain 233 of the transmission component 230 is respectively fixed to the first assembly frame 210 and the cleaning arm 100, the first driven wheel 231 and the second driven wheel 232 are driven to rotate, so that the transmission component 230 alone generates a secondary motion for the cleaning arm 100. When the stroke generated by the first driving part 220 is defined as A, the transmission component 230 alone generates a stroke of A for the cleaning arm 100, so the cleaning arm 100 as a whole generates a 2A stroke, so the transmission component 230 has a superimposed effect on the stroke of the first driving part 220.

[0043] When the cleaning arm 100 of the utility model is retracted, it can be completely stored inside the first assembly frame body 210, and when the cleaning device enters or exits the tank truck 600, the cleaning arm 100 can be protected from being easily damaged.

[0044] The Z-axis moving mechanism 200 is also provided with a first support frame 240, the fixed end of the first driving part 220 is fixedly assembled with the first support frame 240, the first assembly frame body 210 is movably connected with the first support frame 240, the transmission component 230 is fixedly assembled with the first assembly frame body 210, and the transmission component 230 is fixedly assembled with the cleaning arm 100, and the cleaning arm 100 is located inside the first assembly frame body 210 and can movably pass through the first assembly frame body 210.

[0045] The transmission assembly 230 is provided with at least a plurality of groups, and the plurality of groups of transmission assemblies 230 are centrally symmetrically distributed with the central axis of the first assembly frame body 210 as the central axis; in this embodiment, 4 groups of transmission assemblies 230 are specifically provided, and the central axis of the first assembly frame body 210 of this embodiment is centrally symmetrically distributed, and is also symmetrically distributed. Of course, the transmission assembly 230 of the utility model can also be provided with 2 groups, 3 groups, 6 groups, etc., as long as the cleaning arm 100 can perform secondary motion. The first driving part 220 of the utility model is a hydraulic rod.

[0046] There are multiple first drive units 220, and the multiple first drive units 220 are centrally symmetrically distributed with the central axis of the first assembly frame 210 as the central axis. The first drive units 220 of the utility model can also be provided with 3, 4 or more, and the number of the first drive units 220 depends on the size of the cleaning arm 100 and the actual situation. The first drive units 220 of this embodiment are provided with 2 sets as an example for explanation, and the two first drive units 220 of this embodiment are symmetrically arranged on the Z-axis moving mechanism 200.

[0047] It should be noted that the transmission assembly 230 of the present invention and the distribution mode of the transmission assembly 230 and the first assembly frame body 210 improve the stability of the movement of the Z-axis moving mechanism 200 .

[0048] The first assembly frame 210 is specifically a rectangular parallelepiped frame, and the lower end surface of the first assembly frame 210 is provided with a through hole 212 for the washing arm 100 to enter and exit. The first assembly frame 210 is provided with a guide pulley 211, which moves on the side of the rectangular parallelepiped frame and is rollingly connected to the first support frame 240 of the Z-axis moving mechanism 200.

[0049] It should be noted that the first assembly frame 210 of the present invention may also be a cylindrical frame or other three-dimensional frame, as long as it can assemble the cleaning arm 100 and perform Z-axis movement in the first support frame 240 .

[0050] It should be noted that the guide pulley 211 of the present invention rolls with the first support frame 240 acting on the guide support frame 500, thereby improving the stability of the cleaning arm 100 in the Z-axis movement.

[0051] Compared with the prior art, the cleaning device for cleaning a tank truck has the following beneficial effects: the cleaning arm 100 can be extended into the interior of the tank truck 600 for cleaning through the Z-axis moving mechanism 200, without the need for an operator to hold the cleaning arm 100.

The X-axis moving mechanism 300 is assembled with the Z-axis moving mechanism 400, and the Y-axis moving mechanism 400 is movably assembled with the X-axis moving mechanism 300.

[0055] It should be noted that the second driving part 320 of this embodiment may be a hydraulic rod, or other driving devices, such as a linear stepping motor, etc. This embodiment is described by taking the hydraulic rod as an example.

[0056] The Y-axis moving mechanism 400 can also be a hydraulic rod, a linear stepping motor, a motor, a chain, a gear and a pulley, a motor, a gear and a rack, etc. Such a mechanism that can make an object move in a straight line is common knowledge in industrial automation production, and the specific structure of the Y-axis moving mechanism 400 is not the focus of the utility model, so it will not be described in detail in this embodiment.

[0057] In actual use, the cleaning device of the utility model is assembled in the bracket 500 of the tank truck cleaning workshop, and then the tank truck to be cleaned directly drives under the bracket 500, and then the cleaning arm 100 is moved to the top of the manhole of the storage tank 600 by the X-axis moving mechanism 300 and the Y-axis moving mechanism 400, and then the Z-axis moving mechanism 200 drives the cleaning arm 100 to extend into the interior of the tank truck 600 for cleaning, such as Figure 6 As shown, after cleaning is completed, the Z-axis moving mechanism 200 drives the cleaning arm 100 to retract, and then the cleaning arm 100 is moved away from the tank truck through the X-axis moving mechanism 300 and the Y-axis moving mechanism 400.

[0058] Compared with the first embodiment, the present embodiment can control the cleaning arm 100 to move along the X-axis and the Y-axis, thereby making the cleaning device more automated.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
