Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a leveling locking device after a platform is lifted into position. Background Art

[0002] A lifting platform is a lifting machine that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lifting platform is often equipped with various flat conveying equipment as a connecting device for conveyor lines at different heights. It is generally driven by hydraulics, so it is called a hydraulic lifting platform. In addition to being used for cargo transportation at different heights, it is widely used in high-altitude installation, maintenance and other operations. The free lifting characteristics of the lifting platform have been widely used in municipal maintenance, cargo transportation at docks and logistics centers, building decoration, etc., and industries such as automobile chassis and battery car chassis have been installed. The working height space has also changed. It has the advantages of light weight, self-propelled, electric start, self-supporting legs, simple operation, and large working surface. Conventional equipment does not install a leveling locking device, so after the platform reaches the designated floor, due to the structural principle of the equipment itself, the table top will adjust up and down, so the table top will have a certain amount of adjustment and expansion when empty and fully loaded.

[0003] The prior art discloses a motor vehicle maintenance lift with a locking device and application number 202111291991.X, which includes a lifting and locking mechanism, a platform mechanism, a lighting mechanism and a storage mechanism. The locking plate can be driven to move in the longitudinal direction by a first electric telescopic rod, so that the locking plate can support the platform body that has risen to a certain height. When the hydraulic cylinder fails or other unexpected situations cause the platform body to be unable to be fixed at the bottom of the hydraulic cylinder, the height of the platform body can be locked by the locking plate, thereby providing certain protection for the life safety of the maintenance personnel. However, the stability of the locking structure is low, and it is difficult to prevent the lifting platform from falling suddenly, which affects the safety and stability of the use of the lifting platform. Utility Model Content

[0009] Furthermore, a spring in a tension state is provided between one end of the locking rocker and the groove, and two groups of the locking rocker and the groove are symmetrically provided with respect to the locking seat.

[0010] Furthermore, a cushion block is provided on the outer side of one end of the locking rocker, and the cushion block is a rubber block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, a locking slide plate and a locking rod are arranged in the slide groove of the lower pad through a hydraulic cylinder and a hydraulic rod. When the lifting platform reaches a specified height, the locking slide plate and the locking rod are driven by the hydraulic cylinder to move and insert into the first locking groove of the locking seat on one side of the lifting frame, so that both sides of the lifting platform that is adjusted for lifting can be locked. The locking stability is high, which can prevent the lifting platform from falling suddenly, thereby improving the safety and stability of the use of the lifting platform.

[0013] 2. The utility model has a groove on the inner side of the locking seat that is connected to one end of the first locking groove, and a locking rocker is hinged in the groove through a connecting shaft, and a second locking groove that cooperates with the locking rocker is also provided on one side of the lower pad. When the hydraulic cylinder drives the locking rod to be inserted into the first locking groove, one end of the locking rod squeezes the locking rocker, and one end of the locking rocker is inserted into the second locking groove, forming a double-layer locking, so that the locking stability is higher, and a spring in a stretched state is provided between one end of the locking rocker and the groove. When the locking rod is pulled out of the first locking groove, one end of the locking rocker is pulled back into the groove by the pulling force of the spring and is separated from the second locking groove, so that it is convenient and quick to disassemble.
