Embodiment 1

[0028] Embodiment one, see figure 1 , a concrete prefabricated bridge slab production equipment, including a steam shed 6 and a cable tensioning mechanism 7 arranged from right to left.

[0029] The steam shed 6 includes two ground beams 61 arranged in parallel, several shed frames 62 and shed cloth 63 distributed along the extending direction of the ground beams. The ground beam 61 extends in the left-right direction. The two ground beams 61 are a front ground beam 611 and a rear ground beam 612 . Both ends of the frame frame 62 are connected to the two ground beams 61 correspondingly. The tent cloth 63 is fixed on the tent frame 62 .

[0030] The cable tensioning mechanism 7 includes a base 71, two slide rails 72 arranged on the base, a pull rod 73 slidably connected on the slide rails, and a drive cylinder 74 for driving the pull rod to slide on the slide rails. The base 71 defines a mounting hole 711 . The slide rail 72 extends in the left-right direction. The tie ro...

Embodiment 2

[0040] Embodiment two, the difference with embodiment one is:

[0041] see Figure 7 , The inner peripheral surface of the inner sleeve 361 is provided with a swirl piece 368 that guides the pressure limiting cover 36 to rotate when the air flows through the inner sleeve 361 . The sliding cylinder 31 is provided with a connecting frame 312 . The connecting frame 312 is rotatably connected with a circular knife 37 through a plane bearing 313 . The circular knife 37 is aligned with the bottom wall 363 . The outer diameter of the circular knife 37 is equal to the inner diameter of the inner sleeve 261 . The circular knife 37 is provided with a connecting sleeve 371 with the annular groove 364 .

[0042] During use, if the pressure limiting cap 36 is ejected, before the circular knife 37 contacts the bottom wall 363, the connecting sleeve 371 is first inserted into the annular groove 364 for positioning, and then the bottom wall 363 moves closer to the circular knife 37 and is...

Abstract

The invention relates to the technical field of manufacturing of prefabricated pieces for bridge tunnel building. Concrete prefabricated bridge plate production equipment comprises a steam shed internally provided with a cement bridge plate forming mold and a steel cable tensioning mechanism, wherein the steam shed and the steel cable tensioning mechanism are sequentially arranged. The steel cable tensioning mechanism comprises a base, a sliding rail arranged on the base, a pull rod slidably connected to the sliding rail and a driving cylinder for driving the pull rod to slide on the sliding rail. The pull rod is provided with steel cable pass holes extending in the extension direction of the sliding rail, the ends, away from the steam shed, of the steel cable pass holes are provided with conical face sections and conical chucks matched with the conical face sections, and the conical chucks are provided with clamping through holes extending in the axial direction. Each conical chuck is formed by splicing at least two clamping blocks distributed in the circumferential direction of the conical chuck to define the corresponding clamping through hole, and the base is provided with mounting holes. The concrete prefabricated bridge plate production equipment has the advantages that when a steel cable is tensioned, the labor is saved, and the solidification speed can be increased; and the problems that in the concrete prefabricated bridge plate manufacturing process, steel cable manual tensioning is strenuous, and the solidification speed is low are solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing prefabricated parts for bridge and tunnel construction, in particular to a production equipment for concrete prefabricated bridge slabs. Background technique [0002] Among the manufacturing methods of bridge tunnels, etc., there is a method of prefabricating bridge slabs, and then transporting them to the site for splicing. When the concrete prefabricated bridge slab of the rotating shaft bridge is used, some steel cables need to be tensioned and passed through the holes of the concrete prefabricated bridge slab along the length direction of the bridge slab. The existing concrete prefabricated bridge slab is formed by placing the cement bridge slab forming mold on the outdoor field, then putting the SIPG skeleton on hold, pouring concrete and then hardening naturally. The steel cable is tensioned for being pulled by a person. Therefore, the existing concrete prefabricated bridge slab manu...
