[0001] The utility model belongs to the technical field of high-pressure cleaning, and particularly relates to a speed-changing and regulating mechanism for a cleaning vehicle. Background Art

[0002] With the development of technology, dock cleaning vehicles are usually used to remove rust and clean the bottom and low side walls of ships using ultra-high pressure water jet technology. For example, the utility model patent with authorization announcement number CN212861816U discloses a four-wheel cleaning vehicle, in which a high-pressure cleaning and rust removal device is installed at the front end of the four-wheel vehicle, and the cleaning and rust removal operations are performed by controlling the movement of the four-wheel vehicle. Since the four-wheel cleaning vehicle needs to maintain a low speed during the cleaning operation, the transmission ratio of the driving wheel at the front end and the clutch wheel at the rear end needs to reach 4:1 or more in order to effectively control the vehicle speed. However, the current transmission ratio of the driving wheel and the clutch wheel of the four-wheel vehicle is only 2:1, and the driving wheel is already the smallest wheel diameter. Due to space limitations, it is also impossible to adjust the transmission ratio of the two by increasing the wheel diameter of the clutch wheel, thereby affecting the cleaning effect of the cleaning vehicle. Therefore, it is urgent to propose a speed adjustment mechanism for a cleaning vehicle to achieve the adjustment of the transmission ratio of the driving wheel and the clutch wheel and improve the cleaning effect of the cleaning vehicle. Utility Model Content

The waist-shaped hole is connected to the first mounting hole provided on the fixed plate by bolt assembly, and the length direction of the waist-shaped hole is parallel to the mid-perpendicular line connecting the center of the driving wheel and the center of the clutch wheel.

[0007] Preferably, a fixing block is provided on one side of the mounting seat close to the driving wheel and the clutch wheel, an adjusting screw is threadedly connected to the fixing block, and the top end of the adjusting screw is in conflict with the fixing plate.

[0008] Preferably, the mounting seat is provided with two guide bars parallel to the length direction of the waist-shaped hole, and the fixing plate is located between the two guide bars and is slidably connected thereto.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, a speed adjustment mechanism for a cleaning vehicle includes a driving wheel 2 and a clutch wheel 3 which are respectively rotatably connected to the body 1 of the cleaning vehicle, and a speed change assembly located between the driving wheel and the clutch wheel. The speed change assembly includes a fixed plate 4, a transmission shaft 5, and a speed change wheel 6. The fixed plate is connected to the body of the cleaning vehicle, one end of the transmission shaft is connected to the fixed plate, and the other end is rotatably connected to the speed change wheel. The speed change wheel is respectively connected to the driving wheel and the clutch wheel through a transmission belt 7. The transmission shaft is located on the mid-vertical line of the line connecting the center of the driving wheel and the center of the clutch wheel. By adding a speed change wheel, the transmission ratio of the driving wheel and the clutch wheel can be adjusted, thereby improving the controllability of the cleaning vehicle speed and improving the cleaning effect.

[0023] Combine Figure 2 、 Figure 3 and Figure 4As shown, the speed change assembly also includes a mounting seat 8, which is provided with a waist-shaped hole 9. The waist-shaped hole is assembled and connected to the first mounting hole 10 provided on the fixed plate by a bolt 11. The length direction of the waist-shaped hole is parallel to the perpendicular bisector of the line connecting the center of the driving wheel and the center of the clutch wheel. The waist-shaped hole is used to adjust the position of the fixing plate, the transmission shaft and the speed change wheel to adjust the tension of the two transmission belts. After the adjustment is completed, the bolts can be tightened. A fixing block 12 is provided on the side of the mounting seat close to the driving wheel and the clutch wheel. An adjusting screw 13 is threadedly connected to the fixing block. The top of the adjusting screw is in conflict with the fixing plate. When adjusting, first loosen the bolt 11, then screw the adjusting screw, and use the adjusting screw to push the fixing block to the side away from the driving wheel and the clutch wheel, thereby achieving the tension adjustment of the transmission belt. Combined with Figure 5 As shown, the mounting seat is provided with two guide bars 14 parallel to the length direction of the waist-shaped hole, and the fixing plate is located between the two guide bars and is slidably connected thereto, which can effectively improve the stability of the adjustment process.

[0024] In order to facilitate the installation of the mounting base and the body of the cleaning vehicle, the vertical cross-section of the mounting base is L-shaped, and it includes a vertical plate 801 and two side plates 802. The two side plates are symmetrically connected to the lower part of the two sides of the vertical plate. Waist-shaped holes are set on the vertical plate. The bottom ends of the two side plates are connected to the bottom plate 803. The bottom plate is provided with a second mounting hole 15. Figure 1 As shown, the top ends of the two side panels are in contact with the bottom ends of the vehicle body, and the vertical panels are parallel to the surface of the vehicle body. The side panels and the vertical panels can be fixed by welding, or they can be assembled and connected to the vehicle body by bolts using the second mounting holes.

[0025] The working principle of this utility model is as follows:

[0026] like Figures 1 to 5 As shown, before use, the mounting base 8 is first fixed to the body 1 of the cleaning vehicle. Then, the fixing plate 4 is assembled and connected to the waist-shaped hole 9 of the mounting base 8 using bolts 11 to secure the fixing plate 4. The addition of the speed change pulley 6 effectively solves the problem of speed change due to space limitations. During long-term use, the tension of the drive belt 7 can be adjusted periodically by adjusting the position of the fixing plate 4, solving the tensioning requirement in the absence of a tensioning pulley.

[0027] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
