Hydraulic oil cylinder direct-pushing rear-overhang mechanical garage

Abstract

The invention relates to a hydraulic oil cylinder direct-pushing rear-overhang mechanical garage. The mechanical garage comprises a frame, a lower vehicle plate, an upper vehicle plate, a diagonal rod, an inner door frame, an oil cylinder, an upper spherical hinge and a lower spherical hinge, wherein the lower part of the inner door frame is connected with the upper vehicle plate; one end of the diagonal rod is connected with the upper part of the inner door frame, and the other end of the diagonal rod is connected with the upper vehicle plate; the inner door frame is positioned in the frame, and the inner door frame and the frame form a sliding pair; the upper spherical hinge consists of a spherical hinge seat, a cover plate and a steel ball; the steel ball is fixed on the top of the oil cylinder; the lower spherical hinge consists of a concave spherical surface, a steel ball and a bottom plate which are positioned at the bottom of the oil cylinder; the spherical hinge seat of the upper spherical hinge is connected with an upper beam of the inner door frame; and the bottom plate of the lower spherical hinge is placed on the ground. The mechanical garage has the advantages that: 1), the oil cylinder is directly pushed, so that the middle connected part is reduced, and the oil cylinder is relatively simple and reliable; 2), the mechanical garage descends under the action of dead weight without electricity and is environment-friendly and power-saving; 3), the installation mode of the oil cylinder is simple, a forced model is a two-force bar, and the oil cylinder has a good load-carrying capacity; and 4), by using the oil cylinder, the upper vehicle plate is prevented from falling off in any faults.

Description

technical field [0001] The invention relates to a rear-suspension mechanical garage, in particular to a hydraulic oil cylinder straight-top rear-suspension mechanical garage. Background technique [0002] In the existing rear-suspension mechanical garage, the hoisting methods include chain rear suspension and hydraulic rear suspension. The disadvantage of the chain rear suspension is that the car board is lifted by a motor plus chain system. The chains on both sides of the car board will affect the entry and exit of the car, and it is easy to scratch the reflector, etc., and the distance between the chains will become smaller as the size of the civil works becomes smaller. , causing inconvenience; the hydraulic rear suspension is that the oil cylinder drives the steel wire rope or chain and then drives the car plate to rise or fall. After many links, failures are more likely to occur. The hydraulic cylinder straight top and rear suspension mechanical garage developed by our...
