Abstract

The invention discloses a lifting device, belongs to the field of operation and transportation, and relates to winching, lifting and traction. The lifting device is used for solving the problem that in an existing construction site, the accident of top-impacting of a box is prone to occurring. The lifting device comprises a guide rail frame, a ground protection fence arranged at the lower part ofthe guide rail frame and a lifting cage arranged on the guide rail frame, wherein the guide rail frame is provided with an anti-top-impacting mechanism which comprises an upper buffer plate, an upperbuffer hook arranged on the upper buffer plate, a buffer guide frame, an upper buffer plate limiting structure, a lower buffer plate and a lower buffer hook arranged on the lower buffer plate, and theupper buffer plate can slide vertically along the guide rail frame through the buffer guide frame. By arranging the anti-top-impacting mechanism, partial or complete failure of electric protection isavoided, and the accident of top impacting of the box is avoided by mechanical protection. The invention also discloses a use method of the lifting device.

Description

technical field [0001] The invention belongs to the field of operation and transportation, and relates to hoisting, hoisting and traction, in particular to a lifting device and a using method thereof. Background technique [0002] Construction elevators are usually called construction elevators, but construction elevators include a broader definition, and construction platforms also belong to the construction elevator series. A simple construction elevator is composed of a car, a drive mechanism, a standard section, an attached wall, a chassis, a fence, and an electrical system. It is comfortable and safe to ride. The construction elevator is usually used with the tower crane on the construction site. The general load capacity is 1-3 tons, and the running speed is 1-60M / min. The construction elevators produced in our country are becoming more and more mature and gradually going international. [0003] Patent document 201410758329.4 discloses an embedded safety elevator, in...
