Problems solved by technology

[0002] In order to adapt to different working environments and facilitate transition, crawler-type curb paver generally has the function of lifting the whole machine; the operator realizes the adjustment of different working heights of the paver by controlling the expansion and contraction of the telescopic oil cylinder on the outrigger of the paver. The type paver requires a hydraulic motor to drive the drive wheel of the crawler to rotate and then drive the paver to walk, and the power source of the hydraulic motor is hydraulic energy, so the operation of the hydraulic motor needs to be connected to the hydraulic system on the paver through a hydraulic hose Form a hydraulic circuit; when the paver lifts, the relative position of the hydraulic motor and the hydraulic system on the main body of the paver changes greatly, and the layout of the hydraulic pipelines connecting the two will inevitably change; The pipeline between the system and the hydraulic motor is a hydraulic hose, and the length of the hydraulic hose is usually 1.03 to 1.1 times the linear length of the hydraulic motor to the hydraulic joint on the main body of the paver when the outriggers are fully extended. , which is positioned at a point on the fixed part of the leg by a cable tie; but when the paver needs to descend to a height, the telescopic oil cylinder retracts, and the hydraulic pressure changes due to the change of the linear length of the hydraulic joint on the main body of the hydraulic motor to the paver. The length of the hose cannot be changed, such as figure 2 As shown, the hydraulic motor oil inlet pipe, oil return pipe and oil discharge return pipe are combined into one through the hose sheath. At this time, the defects of only using cable ties to fix the hydraulic hose are exposed: one is that the hydraulic hose is damaged. Bending by force causes most of the hoses to hang in the air, and its bending direction is difficult to accurately control, which affects the appearance and is prone to hoses hanging on the track, rubbing against completed or unfinished curbs, etc., which will aggravate the aging of the hydraulic hoses and even Even if the hose sheath is added to the problem of oil leakage, it will not help the severe wear; the second is that the connection position between the hydraulic hose and the hydraulic joint on the hydraulic motor is easy to loose due to irregular force due to the expansion and contraction of the legs. This leads to leakage of hydraulic oil and seriously affects the operation of the paver; third, the cable ties used are prone to aging and fracture due to long-term exposure, which brings hidden dangers to the safe operation of the paver; , Bending at a short distance and large angle will cause the fatigue of the hose or even cause the oil to hold pressure and damage the hydraulic system
