Abstract

The invention provides an improved structure of a positioning ring for a front top hydraulic oil cylinder of a dumper. The structure comprises an oil cylinder cover assembly, an outer cylinder assembly and an oil cylinder positioning ring, wherein the lifting end of the outer cylinder assembly is fixed in the oil cylinder cover assembly; the oil cylinder positioning ring is fixed on the periphery of the outer cylinder assembly; at least four blind holes are circumferentially and uniformly distributed in the outer ring surface of the oil cylinder positioning ring; a buffer nail is arranged in each blind hole; the outer end of the nail rod of each buffer nail extends out of the corresponding blind hole, and is in clearance fit with the inner circumference of the oil cylinder cover assembly; and each buffer nail comprises a nail head, a nail rod extends upward from the center of the upper end face of the nail head, and the diameter of each nail head is slightly more than the diameter of the corresponding nail rod. The improved structure can be used for inhibiting abnormal sound generated by collision between the oil cylinder positioning ring and the metal oil cylinder cover assembly, and has the advantages of simple process, low cost and convenience in popularization and application.

Description

technical field [0001] The invention belongs to the field of dump truck hydraulic oil cylinders, and in particular relates to an improved structure of a positioning ring for a front jack hydraulic oil cylinder of a dump truck. Background technique [0002] The hydraulic cylinder of the dump truck is a hydraulic actuator that converts hydraulic energy into mechanical energy through the hydraulic oil medium; when in action, the oil pump pressurizes the hydraulic oil, and the high-pressure hydraulic oil enters the cylinder to lift, and the hydraulic cylinder is connected to the carriage through the bracket to achieve The function of lifting the carriage upward and unloading the cargo. [0003] Such as figure 1 As shown, the structure of the front jack hydraulic cylinder of the dump truck is: including the cylinder cover assembly, the outer cylinder assembly and the cylinder positioning ring, the lifting end of the external cylinder assembly is fixed in the cylinder cover assem...
