Embodiment Construction

[0008] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0009] Such as figure 1 As shown, it includes special-shaped steel plates 1, bolts 2, and nuts 3.

[0010] In the lifting operation of the present invention, the grooves of the two special-shaped steel plates 1 are placed on the lower end surface of the I-shaped keel steel frame in the machine room, and then the bolts 2 are inserted into the upper holes of the special-shaped steel plates 1 to calibrate their meshing flatness , screw in nut 3 and tighten. This fixing device promptly has been installed, as long as ready-made chain hoist is assisted with shackle to be fixed in the bottom hole of special-shaped steel plate 1 after this, can implement hoisting operation. During operation, the present invention can be slid to a specified position at any time according to needs. When not in use, you only need to remove the shackle and bolts to place it any...

Abstract

The invention relates to a lifting lug fixing device for crane, in particular to a fixing device used for causing a chain block to be conveniently lifted, belonging to the technical field of crane machinery. The lifting lug fixing device comprises irregular shape steel plates, bolts and nuts; the bolt penetrates into the holes arranged at the upper part of the two irregular shape steel plates, meshing evenness thereof is corrected, and the nut is screwed in and locked down. The invention has simple, compact and reasonable structure and is convenient to dismount; the weight thereof is lighter than that of a travelling crane, the exterior volume is smaller than that of the travelling crane, thus reducing material for machine room and space; when in use, only one or two chain blocks are additionally required, so as to realize lifting operation, and easy dismounting can be realized when not in use, thus saving working space.

Description

technical field [0001] The invention relates to a simple and safe fixing device for lifting lugs of a crane, in particular to a fixing device for convenient hoisting of chain hoists, and belongs to the technical field of hoisting machinery. Background technique [0002] In the prior art, since the crane machine room is mostly placed at an altitude of more than 10 meters, it is impossible to use the ground crane equipment for the maintenance and replacement of the internal components of the machine room, and only a simple driving car can be set inside the machine room to carry out the maintenance of the internal components. Setting up a simple crane must require a sufficiently large load-bearing beam and a sufficiently high lifting space, which increases the manufacturing cost of the machine room. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a hoisting lug fixing device that only needs to b...
