Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

Fig. 1 is a schematic structural view of a lifting device provided by an embodiment of the present invention; fig. 2 is a schematic view of an L-shaped hook head structure according to an embodiment of the present invention. As shown in fig. 1, includes: cross arm hoist 1, cross arm hoist 1's crossbeam both ends all are provided with hangs 2, every hangs and all is connected with overhead hoist on 2, overhead hoist includes and hangs 2 first shackle chains 3 that can dismantle the connection, first shackle chain 3's lower extreme is connected with wire rope 4, wire rope 4's lower extreme is connected with second shackle chain 5, second shackle chain 5's below is connected with L type gib head, L type gib head includes bearing wall 61 and contact wall 62, bearing wall 61 is the L type, the one end that contact wall 62 and bearing wall 61 contacted is provided with arc wall 611.

In this embodiment, the crossbeam of cross arm hoist 1 is located the below, and both ends on it all are provided with and hang 2 and be connected with overhead hoist, and as further scheme, hang 2 and be two sets of, be located the both ends of cross arm hoist 1 respectively, and every group hangs 2 and be the rings that a plurality of equidistance set up. The rings are arranged to be conveniently connected and detached with the first shackle chains 3.

In this embodiment, the steel wire rope 4 connected to the lower end of the first shackle chain 3 provides sufficient rigidity for the hoisting process, so that the safety in the hoisting process can be ensured, and the wire breakage can be prevented. The lower end of the steel wire rope 4 is connected with a second shackle chain 5 which is connected with an L-shaped hook head.
