Description

Turnover device suitable for elastic flexible beam

Technical Field

The utility model relates to a can be little with self rigidity, yielding track roof beam when standing up the operation, its track roof beam can not take place to warp, the turnover device who is applicable to elasticity flexible roof beam that can not appear surrender phenomenon belongs to track roof beam turnover device and makes the field.

Background

In the assembling and welding operation of the steel track beam, the beam body can be assembled and welded only after the beam body is limited by the structure and is turned over for a plurality of times. During the operation is stood up to steel track roof beam, because track roof beam rigidity is great, only need set up the lug device on the track roof beam, hang the lug through lifting by crane equipment and just can realize the track roof beam and stand up, but to some self rigidity little, yielding track roof beam sets up the lug device on the roof beam, the roof beam can realize taking place to warp under the dead weight influence when lifting by crane, the phenomenon of surrender appears even, hoist and mount back roof beam body structure size of turning over is super poor, can't resume, the roof beam body stands up the operation and influences roof beam body precision size.

Disclosure of Invention

The design purpose is as follows: the turnover device suitable for the elastic flexible beam is designed, the track beam can not deform and yield phenomenon can not occur when the track beam with small rigidity and easy deformation is turned over, the smooth turning over operation of the beam body is assisted and protected in the turning over process, and the turnover device can be used for turning over large-tonnage workpiece hoisting capacity of equipment with insufficient hoisting capacity by means of the lever labor-saving effect of the turnover device.

The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design, the length, width and height dimensions of this device elasticity flexure roof beam are 30mX2.8mX1.5m, and roof beam body weight is about 75t, as shown in figure 1, mainly by turning over the frame, anchor pin axle, fixing base, support mound etc. and constitute, the frame that stands up in this structure is connected through anchor pin axle and fixing base, and fixing base is fixed subaerial as a fixed turning point with rag bolt, and support mound is connected with turning over the frame with bolt and one side, and one side is used for supporting elasticity flexure roof beam main part. The turning frame is made into an L-shaped structural form, the specific structure is shown in figures 2 and 3, the lower part of the fixing seat is connected with the ground, the upper part of the fixing seat is connected with the turning frame, the specific structural form is shown in figures 4-6, the supporting piers are positioned between the turning frame and the elastic flexible beams and used for supporting the elastic flexible beams, and the structural form of the supporting piers is shown in figures 7 and 8.

The technical scheme is as follows: a turnover device suitable for an elastic flexible beam comprises an L turnover frame, a support pier, an anchoring pin lug, an anchoring pin shaft and a fixed seat, wherein the anchoring pin lug is connected with the root of the L turnover frame, the anchoring pin lug is hinged with the fixed seat through the anchoring pin shaft, the fixed seat is fixed on the ground to serve as a fixed turning point, and the support pier is connected with a frame body of the L turnover frame respectively.

Compared with the prior art, the utility model has the advantages that firstly, the device realizes the stable turnover of the elastic flexible beam, and the supporting beam main body of the supporting pier is arranged to protect the overhanging parts at the two sides of the beam body; secondly, a plurality of hoisting and turning points are arranged to improve the rigidity of the beam body in the turning process, so that the size of the beam body is easy to control; thirdly, the device solves the problem of turning over the overweight beam body, and can realize the turning over of the large-tonnage beam body by means of lifting equipment with smaller tonnage by means of a lever principle by arranging a ground anchor type fixed seat; fourthly, the device has simple structure form, and the structure can be realized by the tailor welding of the section steel; fifthly, the device is fixed with the beam body in the turning process, so that the impact on the beam body in the turning process is avoided; sixthly, the device successfully develops and reduces the turning difficulty and improves the efficiency.
