In order to improve the wear resistance, service life and installation convenience of the pipelines, rubber hoses are added to the pipelines. Due to design reasons, some rubber hoses are installed vertically. The rubber hoses cannot bear weight, otherwise there is a risk of the edge being pressed off. Therefore, the vertically installed rubber hoses need to have corresponding fixed supports to ensure the normal operation of the pipelines.

Application CN201487439U discloses a rubber hose assembly with a plastic collar with a fixed clip, comprising a rubber hose and a fixed collar, wherein the fixed collar comprises a fixed crossbeam, to which a semicircular collar is connected; a collar is mounted on the fixed crossbeam, one end of the semicircular collar is elastically connected to an arc-shaped collar by an elastic sheet, and matching inverted teeth are provided on the mating surfaces of the other end of the semicircular collar and the other end of the arc-shaped collar, which are engaged with each other, and the rubber hose is clamped between the semicircular collar and the arc-shaped collar, and the scheme is suitable for fixing rubber hoses for vehicles of various structures.

[0004] The fixing devices of rubber hoses disclosed in the prior art are mostly slender hoses, which carry a small flow rate when used and are mostly equipped with a protective structure on the outer layer when used. Therefore, there is no risk of the edge of the hose falling off even if it is installed vertically. Therefore, a special fixing device is required for the rubber hose installed vertically during the slurry transportation process to prevent the rubber hose from falling off when working with overweight.
