Problems solved by technology

However, the disadvantages of hydraulic jack transmission are: (1) Factors such as oil leakage in the hydraulic jack system affect the stability and correctness of the movement, so that the hydraulic jack transmission cannot guarantee a strict transmission ratio
(2) Hydraulic jack transmission is sensitive to changes in oil temperature. When the temperature changes, the viscosity of the liquid changes, causing changes in motion characteristics, which affect the stability of the work, so it is not suitable for working under environmental conditions with large temperature changes
(3) In order to reduce leakage and meet certain performance requirements, the manufacturing precision of hydraulic components is required to be high, and the processing technology is more complicated
(4) Hydraulic jack transmission requires a separate energy source, which is not as easy to use as a power supply
(5) The failure of the hydraulic jack system is not easy to check and eliminate
Manual jacks are labor-intensive, have limited space for movement, and need to borrow a certain amount of external force to lift the vehicle, especially not suitable for women
The mechanical parts driven by motors have disadvantages such as unstable power transmission, and they do not have the function of effective movement

Embodiment 1

[0055] Such as figure 1 , 2 As shown, the hydraulic oil circuits of the jack are all located in the bottom plate 1, and the electric pump assembly 4, the oil tank 5 and the manual pump assembly 3 are fixed on the bottom plate 1 in the shape of "pin", and the telescopic cylinder 2 is fixed in the middle of the three. Wherein the position of the telescopic cylinder 2 is closer to the middle part, which will not produce a larger torque due to the load, and avoid the dangerous situation of the jack tipping over during work. Since the oil circuit of the hydraulic system is solidified in the bottom plate 1, the oil circuit diagram obtained by this scheme is as follows Figure 6 As shown, in terms of oil hole design, the length of the oil hole is shortened, which improves the manufacturability of oil hole processing.

[0056] Specifically, at first, 7 deep holes are drilled inward from the side of the bottom plate 1, that is, one of the sides of the bottom plate 1 is selected to be...

Embodiment 2

[0063] Such as image 3 , 4 As shown, the hydraulic oil circuit of the jack is located in the bottom plate 1, the telescopic cylinder (2), the oil tank 5 and the manual pump assembly 3 are fixed on the bottom plate 1 in the shape of "pin", and the electric pump assembly 4 is fixed in the middle of the three. The oil passage on the jack base plate 1 processed in this way is as follows: Figure 7 As shown, such an oil passage is more difficult to process than in Embodiment 1, because the elongated deep hole runs through the entire bottom plate 1 .

[0064] An oil drain valve is added to the oil passage between the telescopic cylinder 2 and the oil tank 5, the valve can effectively maintain the pressure in the telescopic cylinder 2 and the discharge of hydraulic oil, and can meet the requirements of safe operation during the lifting process. The design principle of the oil relief valve 7 adopts the design principle of the one-way valve, but the spring and the structure in the o...

Abstract

The invention discloses a portable electric multifunctional jack. A telescoping cylinder, an oil tank, a manual pump component and an electric pump component are fixed on a base plate. The oil tank is provided with an oil pumping way extending to the telescoping cylinder through the manual pump component and the electric pump component. A decompression pipeline with a decompression valve is disposed between the oil tank and the telescoping cylinder. The portable electric multifunctional jack has the advantages that the jack is capable of lifting cars and helping tire replacement and the like, suitable for solving car trapping, convenient to turn, move and carry, labor-saving, convenient in solving car trapping and lifting cars, simple to operate, long in service life, safe, reliable and capable of self-locking.

Description

technical field [0001] The invention relates to lifting machinery, in particular to a jack. Background technique [0002] Hoisting machinery is an important tool and equipment in modern industrial enterprises to realize the mechanization and automation of the production process, reduce heavy physical labor, and improve labor productivity. Cranes are an important material basis for mechanized operations and are the main fixed assets in some industrial enterprises. For industrial and mining enterprises, port terminals, station warehouses, construction sites, as well as marine development, space navigation and other departments, cranes have become the main productivity factor, and they are working efficiently in production, forming a rational organization of mass production and mechanized flow operations. The foundation is one of the important symbols of modern production. Adding one or two lifting equipment to some key positions will double the labor productivity. [0003] ...
