Embodiment Construction

[0024] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0025] combine figure 1 with figure 2 As shown, an adjustable and detachable self-adaptive floating buffer structure, a piston 5 is installed at the inner end of the hollow piston rod 3, and the circumferential surface of the piston 5 is slidingly matched with the inner wall of the secondary sleeve 4; a buffer plunger is fixed at the center of the cylinder bottom 8 component2.

[0026] The improvements of this embodiment are:

[0027] The hollow piston rod 3 is sleeved with a sleeve 1, and the sleeve 1 is welded to the inner wall of the hollow piston rod 3 to supply oil to the rodless cavity. The inner end of the hollow piston rod 3 is provided with a notch, and a buffer ring 6 is floatingly installed in the notch at the inner end of the hollow piston rod 3 . The piston 5 is in the shape of a cylinder,...

Abstract

The invention discloses an adjustable and detachable self-adaptive floating buffering structure, and belongs to the technical field of hydraulic cylinder buffering. The structure is characterized in that a buffering ring is arranged in an inner-end spigot of a hollow piston rod in a floating manner; a piston end face abuts against the outer side face of the buffering ring; a buffering plunger assembly comprises a buffering plunger; a main oil passage is formed in the axis of the buffering plunger, one end of the buffering plunger is conical, a throttling hole is formed in the buffering plunger, and the buffering plunger is inserted into the inner end of the hollow piston rod in a matched mode; valve holes which are uniformly distributed and communicate with the main oil passage are formedin the other end of the buffering plunger; and buffering steel balls are arranged in the valve holes, buffering screw plugs are arranged at the outer ends of the valve holes, and the buffering screw plugs are provided with through holes communicating the valve holes. According to the detachable and adjustable buffering structure, the disassembly and assembly difficulty can be greatly reduced, theproblems that the research and development test period is long, the repair time is long and replacement can be achieved only after destructive disassembly are solved, the requirements of clients can be rapidly met, and through mutual cooperation and superposition of multiple buffering structures, the buffering performance is refined, the impact is effectively reduced, the lifting stability is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder buffering, in particular to an adjustable and detachable self-adaptive floating buffer structure. Background technique [0002] Mining dump truck is a large-scale transportation machinery used in various large-scale open-pit mining areas, water conservancy and hydropower projects, etc. It generally works 24 hours a day and belongs to non-road vehicles. The road conditions of the mining dump truck are very poor. As the executive mechanism of the mining dump truck body, the lifting cylinder is frequently unloaded. The reliability and safety of the hydraulic cylinder directly determines the safety of the whole machine unloading. And efficiency, at present, the lifting cylinder, which is the main actuator of the mining dump truck, has the problems of large volume, too many welding points, difficult processing, high cost, large impact vibration, and high impact noise. [0003] In order to s...
