Embodiment 1

[0025] In order to make the present invention clearer, a hydraulic lift with a self-locking device of the present invention will be further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] see figure 1 , figure 2 , a hydraulic lift with a self-locking device, including a base 1 and a lifting platform 2, a pair of scissor arms 3 are connected through a pulley block 7 between the two, and each scissor arm 3 is composed of an inner support rod 3a and an outer support rod 3a. The middle part of the support rod 3b is hinged, and a first connecting rod 4 is horizontally fixed between the middle parts of each pair of inner support rods 3a, and a second connecting rod 5 is horizontally fixed between the bottoms of each outer support rod 3b. A set of hydraulic cylinders 6 for providing lifting is hinged between the rod 4 and the second con...

Abstract

The invention relates to a hydraulic lift with a self-locking device, comprising a base (1) and a lifting platform (2), with a scissor arm (3) connected between them, which consists of an inner support rod (3a) and an outer support rod (3b) The middle part is hinged, and the first connecting rod (4) is horizontally fixed between each pair of inner support rods (3a), and the second connecting rod (5) is horizontally fixed between each pair of outer support rods (3b). A set of hydraulic cylinders (6) and a self-locking device (8) are hinged between the rod (4) and the second connecting rod (5). The self-locking device (8) includes a fixed seat (81), a connecting seat (82) ), movable seat (83) and cylinder (84), connecting seat (82) and movable seat (83) are all hinged with the first connecting rod (4), and fixed seat (81) is hinged with the second connecting rod (5). The invention has the advantages of providing supporting force, reducing the amount of subsidence, and ensuring the stability of the equipment.

Description

technical field [0001] The invention relates to the technical field of hydraulic lift equipment, in particular to a hydraulic lift with a self-locking device. Background technique [0002] Hydraulic lifts are widely used in factory loading and unloading transportation, especially hydraulic lifts for lifting platforms. They are currently a very widely used vertical cargo transport equipment. They are popular among users for their low price, large load capacity and simple installation. However, hydraulic lifts have a big disadvantage: the sinking is very large after loading, which affects the entry and exit of goods. The main factors affecting the sinking of the hydraulic lift are the load capacity, the metal structure of the main body of the equipment, the oil cylinder and the processing accuracy of the equipment, etc. [0003] First of all, metal has the characteristics of elastic expansion and contraction. Under the influence of gravity after loading, the metal structure o...
