Further measures taken are: the main shaft include vertical axle and install at the horizontal axis in vertical axle top, the top of horizontal axis is equipped with the lifting eye, the perpendicular installation guard plate in horizontal axis both ends.
Further measures taken are: the junction of horizontal axis and vertical axle be equipped with the strengthening rib, the junction of horizontal axis and guard plate is equipped with the strengthening rib.
Through the technical scheme, compared with the prior art, the utility model, the beneficial effect who has is as follows:
1. the utility model discloses be fixed in the main shaft below the stay cord with adjustable the regulation structure, through adjusting the stay cord, realize adjusting device and raise and descend along the main shaft, need not to scramble the operation and can carry out lifting by crane and the installation of web to use manpower sparingly and material resources, improve production efficiency, and avoided personnel to scramble the operation and cause the incident.
2. The utility model discloses a adjust the flexible difference of adjusting the total length of adjusting the structure with the surperficial size and the web equipment room of adaptation web for the clamp plate just extends to the web inboard, and clamp plate and horizontal plate increase respectively with the inboard and the turn-ups area of contact of web simultaneously, thereby realize adjusting structure and web and turn-ups along with the shape contact, and the atress is even, reaches the effect that protection web and turn-ups avoided the damage.
3. The utility model has the advantages that the protective baffles on the two sides of the main shaft play roles of fixing and protecting and preventing the webs on the two sides from falling off, and the two lifting holes on the top of the horizontal shaft can be conveniently lifted and transported; the reinforcing ribs on the main structure can enhance the rigidity and the strength of the main structure and overcome structural deformation caused by uneven stress.
4. The utility model discloses a rotation of bracing piece can be realized to the rotation axis on the bracing piece to carry out more accurate location and fixed distance.
