Abstract
The utility model provides a preposition telescopic sleeve hydraulic cylinder back cover of a dumper. The preposition telescopic sleeve hydraulic cylinder back cover comprises a hydraulic cylinder, a back cover body is arranged at the bottom of the hydraulic cylinder, a neck is arranged on the inner wall of the bottom of the hydraulic cylinder, and a steel cable baffle ring or a jump ring is arranged in the neck and matched with the back cover body to form a clamping-connection type structure. By means of the preposition telescopic sleeve hydraulic cylinder back cover, the back cover body is used in cooperation with the steel cable baffle ring or the jump ring, the structure is conveniently assembled, and the shortcoming of excessive design of the structure of a traditional back cover is overcome. Through the theoretical calculation and the pressure test, the using effect can be guaranteed by the method, the number of parts on the back cover part is decreased from ten to two, the weight is light, cost is low, and the product attractive performance is further improved.
Description
Technical field
The utility model relates to the preposition telscoping hydaulic cylinder of dumping car, relates in particular to the preposition telscoping hydaulic cylinder bonnet of dumping car.
Background technique
At present, domestic Tipper Lifting mode adopts preposition telscoping hydaulic cylinder mostly, and traditional sleeve hydraulic cylinder back cover portion is formed by bonnet, block, spring washer, bolt combination.Because traditional sleeve hydraulic cylinder firmly carries 30Mpa with interior pressure in order to guarantee that bonnet is installed simultaneously, need to be by three blocks spacing and bonnet is fixed with six bolts and spring washer.As shown in Figure 3,4, in figure, 1 is bonnet one, the 2nd, block, the 3, the 4th, screw and screw are evenly provided with six screws 4 on bonnet 1 when use, the block 2 of three deciles is fixed on by screw 3 below bonnet 1, with the fixing stationary structure that forms of oil hydraulic cylinder, the required number of spare parts of this structure is many, assembles loaded down with trivial details, weight is large, and cost is also higher.
Summary of the invention
The utility model, in order to optimize assembling, makes up the deficiency of traditional rear cover structure surdimensionnement, the special preposition telscoping hydaulic cylinder bonnet of dumping car that proposes.
The technical solution of the utility model is for this reason, and the preposition telscoping hydaulic cylinder bonnet of dumping car, comprises oil hydraulic cylinder, the bottom of oil hydraulic cylinder is provided with bonnet, it is characterized in that: on the inwall of oil hydraulic cylinder bottom, be provided with draw-in groove, and be provided with back-up ring in draw-in groove, and bonnet coordinates formation clamp connection structure.
Improvement to such scheme is: described back-up ring is Steel Cable Baffle Ring or jump ring.
Beneficial effect:
The utility model is used in conjunction with by bonnet and Steel Cable Baffle Ring or jump ring, Standard facility, optimize the deficiency of traditional bonnet one structure surdimensionnement, calculate and pressure test through theoretical, the method not only can guarantee using effect, and this back cover portion number of spare parts is reduced to 2 by 10, lightweight, cost is low, also makes the attractive in appearance of product improve.
