Problems solved by technology

Domestic lift garages generally use chains or wire ropes to control the lift of the garage. They also use hydraulic cylinders with better effects, lower costs, and lower power consumption. However, the problem of synchronizing multiple cylinders cannot be solved. , the error reaches more than 10% per meter, resulting in unstable lifting effect of the garage, which restricts the development of the hydraulic cylinder lift garage
At present, synchronizers are also installed in hydraulic cylinder lift garages to control the synchronization of multiple oil cylinders, but this will greatly increase the production cost and use cost, and there are still defects such as poor use effect and unstable performance.

Embodiment 1

[0020] Embodiment 1: as figure 1 As shown, a multi-cylinder synchronizing device includes a lifting cylinder 1, a thread cap 2, a sphere 3, a top cover 4, and a shelf 5. The top of the lifting cylinder 1 is fixedly connected with the thread cap 2, which is threaded in this embodiment. A movable spheroid 3 is arranged in the silk cap 2, and there is a gap between the spheroid 3 and the surroundings of the silk cap 2, and the gap between the spheroid 3 and the surroundings of the silk cap 2 is 2 millimeters. The top cover 4 is fixedly connected to the lower end of the shelf 5. The bottom of the top cover 4 contains a sphere 3 and a silk cap 2. There is no gap between the sphere 3 and the top cover 4 and the lifting cylinder 2. The sphere 3 is under the top cover 4 and under the silk cap. 2 can move freely, and the spheroid 3 is a steel ball. There is a gap between the silk cap 2 and the top cover 4, the present embodiment gap is 2 millimeters, and there is a gap between the top...

Abstract

The invention discloses a multi-oil-cylinder synchronizing device. The device comprises a lifting oil cylinder, a threaded cap, a ball body, a top cover and a frame. The device is characterized in that the threaded cap in which the movable ball body is arranged is fixedly connected to the top part of the lifting oil cylinder; the top cover is fixedly connected to the lower end of the frame; the ball body and the threaded cap are arranged below the top cover; the ball body is arranged to the top cover and the lifting oil cylinder without clearances; a clearance is formed between the ball body and the surrounding of the threaded cap; another clearance is formed between the surrounding of the threaded cap and the top cover. When using in a lifting garage, the frame of the multi-oil-cylinder synchronizing device is fixed on the lower surface of a lifting cover plate; when lifting the garage, the ball body frictionally slides up and down and a certain clearance between the surroundings of the ball body is utilized to adjust a plurality of lifting hydraulic oil cylinders to move up and down and synchronous with guide rails of the lifting garage, and therefore, the garage can smoothly, vertically and safely run.

Description

technical field [0001] The invention relates to a hydraulic device, in particular to a mechanical synchronization device of a hydraulic oil cylinder. Background technique [0002] Along with the substantial increase of personal car ownership in our country, the problem of difficult parking has become more and more prominent in cities, and many underground garages have appeared, including lift garages, double-row or multi-row underground garages. Domestic lift garages generally use chains or wire ropes to control the lift of the garage. They also use hydraulic cylinders with better effect, lower cost, and lower power consumption. However, the problem of synchronizing multiple cylinders cannot be solved. , The error reaches more than 10% per meter, resulting in unstable lifting effect of the garage, which restricts the development of the hydraulic cylinder lift garage. At present, synchronizers are also installed in hydraulic cylinder lifting garages to control the synchroniz...
