Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and suctioning sewage vehicles, in particular to a vacuum pump fixing device for cleaning and suctioning sewage vehicles with a belt tension adjustment function. Background Art

[0002] A sewage cleaning and suction truck is a specialized vehicle used to clean urban streets, sewers, septic tanks, and other locations. Combining high-pressure cleaning and vacuum suction, it efficiently removes a wide range of dirt and sewage. These vehicles are typically equipped with a high-pressure water pump, vacuum pump, sewage tank, and nozzles to flush, suck, and store waste. They are widely used in municipal sanitation, petrochemicals, construction sites, and other fields, providing crucial support for urban environmental sanitation management.

[0003] Existing vacuum pumps in sewage cleaning and suction trucks are driven by a belt, with power being transferred from the engine's power take-off (PTO) through a drive shaft. Consequently, belt tensioning is often adjusted using a tensioner. This approach presents two challenges: first, interference with the vacuum pump's mounting position on some vehicle models prevents the belt tensioner from being installed; second, the belt, if stretched during use, requires replacement, resulting in high maintenance costs. Summary of the Invention

[0004] The purpose of the utility model is to provide a vacuum pump fixing device for a cleaning and suction truck with a belt tension adjustment function, which can adjust the movement of the vacuum pump according to needs to achieve the purpose of adjusting the belt tension, and solve the problem that some models cannot install the belt tensioner due to position interference, and the belt needs to be replaced after being stretched.

[0005] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0006] A vacuum pump fixing device for a cleaning and sewage suction truck with a belt tension adjustment function is characterized in that it includes a vacuum pump fixing base, on which a vacuum pump, a secondary transmission shaft, a belt, and a transmission shaft are fixed; a sliding groove is provided on the vacuum pump fixing base, in which the vacuum pump is fixed and can move; a fixing block is provided on the vacuum pump fixing base, and an adjusting bracket screw is provided on the fixing block, the adjusting bracket screw passes through the fixing block, the bottom of the adjusting bracket screw is connected to the adjusting bracket, and the side of the adjusting bracket fits the vacuum pump.

[0007] Improvement on the above technical solution: limit blocks are respectively provided on the left and right sides of the fixed base of the vacuum pump to limit the left and right movement of the vacuum pump.

[0008] Further improvement to the above technical solution: the sliding groove on the fixed base of the vacuum pump is a waist-shaped round hole, and the vacuum pump moves in the waist-shaped round hole, and the adjustment range of the movement is 20 mm.

[0009] A further improvement to the above technical solution: the vacuum pump is fixed in the sliding groove of the vacuum pump fixing base by a vacuum pump fixing bolt.

[0010] Further improvement to the above technical solution: when the vacuum pump needs to adjust the belt tightness, loosen the vacuum pump fixing bolt and tighten the adjusting nut of the adjusting bracket screw. At this time, the adjusting bracket drives the vacuum pump to move, thereby achieving the effect of adjusting the belt tightness. Beneficial effects

[0011] The utility model discloses a vacuum pump fixing device for a cleaning and suction truck with a belt tension adjustment function. A sliding groove is provided on the base of the vacuum pump, and the vacuum pump can move within the sliding groove. When the belt tension of the vacuum pump needs to be adjusted, the vacuum pump fixing bolt is loosened and the adjusting nut of the adjusting bracket screw is tightened. The adjusting bracket then drives the vacuum pump to move, achieving the effect of adjusting the belt tension. Through adjustment, the vacuum pump for a cleaning and suction truck can be applied to cleaning and suction trucks of various specifications and models, effectively solving the problem of adjusting the belt tension.
