Abstract

The utility model discloses a kind of Multi-stage cylinder anticollision ring, it is comprised of steel substrate anticollision ring and cylindrical nylon pad, and described cylindrical nylon pad is a plurality of being evenly distributed, and embedding is fixed on described matrix anticollision ring periphery.Adopt this structure dumping car Multi-stage cylinder anticollision ring to have advantages of that vibrating noise is low, wearing and tearing rear surface vestige is not obvious, cost reasonable, long service life, easy to maintenance.

Description

Multi-stage cylinder anticollision ring

Technical field

The utility model relates to self-unloading truck used hydraulic elevating system sinciput formula single-action multi-stage oil cylinder, is specifically related to Multi-stage cylinder anticollision ring.

Background technique

Multi-stage oil cylinder, because of its compact structure, can be realized the stroke that single-stage oil cylinder can not be realized in limited space, thereby is widely used in the dump ram of dumping car, among the institutions such as the shoveling oil cylinder of refuse storage area and equipment carrying bridge.Dumping car sinciput formula single-acting Multi-stage cylinder is owing to having the stroke of overlength, cause the Multi-stage cylinder deviation that sleeve is accumulated on straight line after stretching out completely much larger than single-stage cylinder, thereby in the process at dumping car with Multi-stage cylinder retraction, cylinder body on being assemblied in vehicle frame needs guiding while returning the urceolus being assemblied on compartment, this guide elements is called anticollision ring.Existing anticollision ring generally adopts two kinds of structures, a kind of is as shown in Figure 1, anticollision ring integral body is made by iron and steel material quality, this durable cost firm in structure is low, but guiding clearance is large, metal bump easily produces vibration and noise, thereby and easily on anticollison block, form obvious scar and affect outward appearance and product public praise; Another kind of structure as shown in Figure 2, made by nylon by anticollision ring integral body, and two ends are fixed with iron and steel, and this structural vibration noise is low, and wearing and tearing rear surface vestige is not obvious, but cost is high, is not durable, and maintain and replace is difficult for.

Summary of the invention

The purpose of this utility model is to provide that a kind of vibrating noise is low, wearing and tearing rear surface vestige is not obvious, cost rationally, long service life, dumping car Multi-stage cylinder anticollision ring easy to maintenance.

For realizing above object, the utility model Multi-stage cylinder anticollision ring is comprised of steel substrate anticollision ring and cylindrical nylon pad, and described cylindrical nylon pad is a plurality of being evenly distributed, and embedding is fixed on described matrix anticollision ring periphery.

Described cylindrical nylon pad is four.

In dumping car self-unloading operation, when cylinder body bounces back, by cylindrical nylon pad, first collide urceolus, then produce guiding strength oil cylinder is retracted smoothly; Adopt this its guiding clearance of structure Multi-stage cylinder anticollision ring only have former steel structural collision protection ring guiding clearance 1/3, make its alignment error lower, and Yin Nilong hardness is soft compared with iron and steel, so this structure has the vibration of reduction, noise simultaneously, the features such as fabricating cost is not high, and surface abrasion vestige is not obvious.

Said structure Multi-stage cylinder anticollision ring has been taken into account the advantage of two kinds of structure Multi-stage cylinder anticollision rings in prior art and has been overcome the shortcoming of two kinds of structures, and mechanism is sturdy and durable, easy to maintenance, and cost is relatively low, and vibrating noise is little, is difficult for forming noticeable wear vestige.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

The Multi-stage cylinder of the utility model shown in Fig. 3 ~ Fig. 4 anticollision ring is comprised of steel substrate anticollision ring 1 and cylindrical nylon pad 2, described cylindrical nylon pad 2 is four and is evenly distributed, and embed and to be fixed on described matrix anticollision ring 1 periphery, adjacent two cylindrical nylon pads 2 are separated by 90 °.

Claims

1. a Multi-stage cylinder anticollision ring, is characterized in that: it is comprised of steel substrate anticollision ring and cylindrical nylon pad, and described cylindrical nylon pad is a plurality of being evenly distributed, and embedding is fixed on described matrix anticollision ring periphery.

2. Multi-stage cylinder anticollision ring according to claim 1, is characterized in that: described cylindrical nylon pad is four.
