The invention discloses a lifting platform locking device, and relates to the field of lifting platforms. A control system controls motion of a power device. A guide rail is arranged on one side of astand column. The two ends of the guide rail are each provided with a limiting part, and the limiting parts are used for limiting an upper guide rail sliding seat and a lower guide rail sliding seat correspondingly. The upper guide rail sliding seat and the lower guide rail sliding seat are mounted on the guide rail in a sliding manner. An upper bent plate and a lower bent plate are fixed to one side of the upper guide rail sliding seat and one side of the lower guide rail sliding seat correspondingly, and an upper mounting hole and a lower mounting hole are symmetrically formed in the upper bent plate and the lower bent plate correspondingly. The power device is fixedly arranged on the lower bent plate, and the output end of the power device is connected with a lead screw. The lead screwsequentially penetrates through the lower mounting hole and the upper mounting hole from bottom to top. A nut used for matching with the lead screw is fixed to the upper bent plate. The control systemcontrols motion of the power device to enable the upper bent plate and the lower bent plate to lock a lifting platform located at any height. The lifting platform locking device is low in labor intensity and high in locking reliability.
Description
technical field [0001] The invention relates to the field of lifting platforms, in particular to a locking device for lifting platforms. Background technique [0002] In actual production, there are many lifting platforms that can stop at any position within a certain height range, and require reliable locking of the lifting platform, that is, the lifting platform cannot undergo any form of displacement in the horizontal plane. However, most of the traditional lifting platform locking devices are manual locking devices, which are labor-intensive and have low locking reliability. [0003] Therefore, it is an urgent problem to be solved at present to provide a lifting platform locking device with low labor intensity and high locking reliability. Contents of the invention [0004] The object of the present invention is to provide a lifting platform locking device to solve the above-mentioned problems in the prior art, so that the lifting platform locking labor intensity is l...
