Ultrahigh-pressure water slip ring

Abstract

The invention relates to the field of slip rings, in particular to an ultrahigh-pressure water slip ring. The ultrahigh-pressure water slip ring comprises a shaft core and a shell arranged outside theshaft core in a sleeving mode, wherein a top connector is detachably arranged at one end of the shell, a groove allowing the end of the shaft core to be inserted is formed in the top connector, and the end of the shaft core is rotationally connected with the top connector; two first ball bearings which are located on the outer side of the shaft core and are coaxial with the shaft core are sequentially arranged in the shell in the direction away from the top connector, the two first ball bearings are rotationally connected with the shaft core, a roller bearing is arranged between the two firstball bearings and rotationally connected with the shaft core, and bearing spacer bushes are arranged between the first roller bearing and the two first ball bearings; and the end, away from the top connector, of the shell is rotationally connected with the shaft core. The roller bearing is used for bearing the acting force transmitted by the shaft core in the radial direction, so that the shaft core and the shell can normally rotate relative to each other, then the abrasion degree between the shaft core and the shell is reduced, and the service life of the water slip ring is prolonged to a certain extent.

Description

technical field [0001] The present application relates to the field of slip rings, in particular to an ultra-high pressure water slip ring. Background technique [0002] In the field of building construction, aluminum formwork systems are often used. After the construction of the project is completed, the surface of the aluminum formwork needs to be cleaned. In order to improve work efficiency and reduce the cleaning workload of the staff, existing enterprises generally use spray The aluminum membrane plate is washed by a cleaning machine with ultra-high pressure water flow. When the cleaning machine is working, in order to improve the flushing efficiency, the nozzle needs to be rotated when spraying ultra-high pressure water to spray the water to different positions on the surface of the aluminum formwork. For this reason, a water slip ring is generally used to connect the nozzle and the water inlet pipe. Relative rotation is formed between the spray head and the water inl...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventors found that since the nozzle needs to rotate at high speed and continuously spray water under the action of ultra-high pressure, although the existing water slip ring can meet the requirements of the cleaning machine, after 50h-60h continuous use , the wear of the water slip ring is relatively serious, which seriously affects the normal ejection of high-pressure water flow, and the service life is short
