According to the further technical scheme, a threaded hole is formed in the bracket above the slot and communicated with the slot.

According to a further technical scheme, the threaded rod is arranged on a symmetry line of the upper platform.

The beneficial effects of the utility model

The fork truck suspends the bracket on the fork truck through the slot, the landing leg inserts in the landing leg and can be in the free activity of male orientation, go up the landing leg and fix the platform bottom, this technical scheme guarantees that the upper mounting plate can freely go up and down in vertical orientation, the upper mounting plate bottom still is fixed with the threaded rod, the threaded rod with locate the spliced pole screw-thread fit on the bracket, be equipped with the helical gear on the threaded rod, still be equipped with L type panel beating on the spliced pole, be equipped with the connecting rod on the L type panel beating, the connecting rod is rotatory with the bearing cooperation of fixing in the support seat on the L type panel beating, be equipped with the helical gear one with the mutual interlock of helical gear on the connecting rod, connecting rod one end still is fixed with the carousel, through rotatory carousel, the carousel drives the connecting rod rotatory, helical gear one on the connecting rod and the helical gear on the threaded rod turn into the horizontal motion of connecting rod and move in the vertical orientation of threaded rod, and then make the platform lift on the connecting rod, and then under the fork truck power promotion, the bracket jack-up the bailey beam, hoisting with the help of external crane, protect the bailey beam not damaged, demolish efficiently, time to the traffic control reduces greatly.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic diagram of the structure of the bracket of the present invention;

fig. 3 is a schematic view of a mounting structure of the helical gear of fig. 2 according to the present invention.

In the figure: the bridge comprises a bridge pier 1, a Bailey beam 2, a bracket 3, a slot 4, a support leg 5, a threaded rod 6, a bevel gear 7, an upper platform 8, a metal plate 9L, a turntable 10, a connecting rod 11, a bevel gear 12I, an upper support leg 13, a connecting column 14 and a threaded hole 15.

Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

Referring to fig. 2-3, the urban bridge combined support dismantling bracket comprises a bracket 3, wherein a slot 4 matched with a forklift is formed in the bracket 3, four support legs 5 are arranged on the bracket 3, the 4 support legs 5 are inserted into four upper support legs 13 and can freely move in the inserting direction, and the 4 upper support legs 13 are fixed at the bottom of an upper platform 8, so that the technical scheme ensures that the upper platform 8 can freely lift in the vertical direction, and the support legs 5 are matched with the upper support legs 13 to play a role in guiding;

the bottom of the upper platform 8 is also fixedly provided with a threaded rod 6, the threaded rod 6 is in threaded fit with a connecting column 14 arranged on the bracket 3, specifically, a threaded hole is formed in the connecting column 14, one end of the threaded rod 6 is in matched rotation with the threaded hole, a helical gear 7 is arranged on the threaded rod 6, an L-shaped metal plate 9 is further arranged on the connecting column 14, a connecting rod 11 is arranged on the L-shaped metal plate 9, the connecting rod 11 is in matched rotation with a bearing in a supporting seat fixed on the L-shaped metal plate 9, a helical gear I12 meshed with the helical gear 7 is arranged on the connecting rod 11, and a turntable 10 is further fixed at one end of the connecting rod 11; in order to better fix the bracket 3 with the forklift, a threaded hole 15 is formed in the bracket 3 above the slot 4, the threaded hole 15 is communicated with the slot 4, a bolt is inserted into the threaded hole 15, the forklift is screwed and fixed, and in order to enable the upper platform 8 to lift stably, the threaded rod 6 is arranged on a symmetrical line of the upper platform 8 to ensure that the upper platform 8 is synchronous when being lifted. When the bailey beam 2 on the pier 1 needs to be dismantled, the bracket 3 is lifted to a proper height by manually rotating the turntable 10, the height of the bailey beam 2 on the actual pier 1 is determined, the adjustment is performed by the skilled person, the forklift is started at the moment, the bailey beam 2 is jacked up by the bracket 3 under the driving of the forklift, in order to enable jacking to be stable, as shown in fig. 1, the two brackets 3 are placed below the bailey beam 2 and are jacked synchronously, the bailey beam 2 moves transversely when jacked up, the bailey beam 2 is moved out of the pier 1 and is hoisted through an external crane, and the dismantling operation of the bailey beam 2 is completed. This practicality lifts the support through fork truck, slowly shifts out bailey roof beam on the pier, prevents that bailey roof beam is damaged and warp, has changed the tradition and has built the scaffold frame, perhaps directly use the crane, dig that destroy the traffic when the machine demolishs, destroy bailey roof beam problem.
