Embodiment Construction
[0021] The embodiment of the present invention solves the technical problem of being unable to self-lock and unlock in the prior art by providing a lifting device, and realizes the technical effect of the self-lock and unlock function.
[0022] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the general idea is as follows:
[0023] The clamping plate and the pressing plate are designed to be in inclined contact, and the clamping plate enters the second groove on the guide rod under the action of the telescopic rod of the fluid cylinder to realize self-locking; the clamping plate is released from the second groove under the pressure of the pressing plate Move out to realize unlocking, thereby realizing the self-locking and unlocking functions of the embodiment of the present invention.
[0024] In order to better understand the above technical solution, the above technical solution will be described in de...

The invention discloses a lifting device. The lifting device at least comprises a guiding rod, a fluid cylinder, an elastic component, a locking plate, a cover plate, a pressing plate and a guiding sleeve. A first groove is installed in the guiding rod. A telescopic rod of the fluid cylinder is protruded into the first groove. The pressing plate is installed on the telescopic rod. The guiding sleeve is sheathed on the guiding rod. The cover plate is connected with the guiding sleeve. The locking plate is installed in the cover plate. The elastic component is installed between the cover plate and the locking plate, and the initial sate of the elastic component is the compressed state. The elastic force direction of the elastic component faces to the outer wall of the guiding rod. The locking plate contacts with the inclined surface of the pressing plate. The outer wall of the guiding rod is provided with a second groove. According to the lifting device, the locking plate and the pressing plate are designed as the contract of the inclined surface, the locking plate is extended into the second groove on the guiding rod under the action of the telescopic rod of the fluid cylinder, so the self-locking is realized; and the locking plate is removed from the second groove under the pressure action of the pressing plate, the unlocking is realized, so the self-locking and the unlocking functions of the lifting device are realized.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a lifting device. Background technique [0002] Lifting equipment is a kind of equipment that can realize the lifting or lowering of the carried items. Simple, efficient, and reliable lifting equipment meets the needs of use and cost. At present, with the development of modern production and applications, the requirements for the performance of lifting equipment are getting higher and higher. In many occasions, it is required that the lifting equipment can realize self-locking at a specific position to prevent the equipment from slipping or shaking under the action of external force. Thereby affecting the stability of the carried items, causing certain accidents, and requiring the device to be unlocked simply and reliably. At present, existing lifting equipment lacks self-locking and unlocking mechanisms. Contents of the invention [0003] The present invention solves the t...
