In order to achieve the purpose, the bolt mounting and dismounting auxiliary device for the tower crane comprises a standard section, a supporting plate assembly and a fixing plate, wherein the standard section is provided with a flange plate, and the fixing plate is used for fastening the supporting plate assembly;
the supporting plate assembly comprises two supporting plates in a sector ring shape, the bottom of each supporting plate is fixed with angle steel, the angle steel is provided with a first connecting hole, and a connecting piece is arranged in the first connecting hole;
the fixed plate is arranged on the standard knot below the flange plate, a second connecting hole matched with the first connecting hole is formed in the fixed plate, and the supporting plate assembly is fastened with the fixed plate through a connecting piece.
As an improvement, two ends of the bottom of each supporting plate are welded with angle steels.
As a refinement, the connecting piece comprises a connecting bolt and a connecting nut.
As an improvement, the fixing plate is welded on the standard knot.
As an improvement, the fixing plates are arranged in a plurality of numbers, and the fixing plates are circumferentially arranged on the standard knots.
Compared with the prior art, adopt the utility model discloses an auxiliary device is torn open in bolt ann can only need tear the nut on the high strength bolt open when tower and the transportation of transition, and the bottom of high strength bolt can fall on the layer board, need not dismantle the high strength bolt completely, like this when the tower is found once more to needs, can directly install the nut at the high strength bolt top can, saved a large amount of time. The device has simple structure and convenient installation and use.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, 2 and 3, the auxiliary device for mounting and dismounting the bolts for the tower crane comprises a standard joint 5, a supporting plate assembly and a fixing plate 6 for fastening the supporting plate assembly, wherein a flange plate 4 is mounted on the standard joint 5;
the supporting plate assembly comprises two supporting plates 1 in a fan-shaped ring shape, angle steel 2 is fixed at the bottom of each supporting plate 1, a first connecting hole is formed in each angle steel 2, and a connecting piece 3 is installed in each first connecting hole;
the fixed plate 6 is arranged on the standard knot 5 below the flange plate 4, a second connecting hole matched with the first connecting hole is formed in the fixed plate 6, and the supporting plate assembly is fastened with the fixed plate 6 through the connecting piece 3.
As the improvement of embodiment, the both ends of every layer board 1 bottom all weld one angle steel 2, and the installation steadiness is good, and the raw materials is easily obtained, and is with low costs. In a further improvement, the connecting piece 3 comprises a connecting bolt and a connecting nut, and the supporting plate 1 is installed on the fixing plate 6 more conveniently.
As a modification of the embodiment, the fixing plate 6 is welded to the standard knot 5. As a further improvement of the embodiment, the fixing plates 6 are provided in several numbers, and the fixing plates 6 are arranged on the standard knot 5 in a circumferential manner. When two fan-shaped supporting plates 1 are fastened on the standard knot 5 through the fixing plate 6 respectively, the supporting plates 1 are ensured to be in a horizontal state, and the high-strength bolts 7 can be stably supported.
