Description

Technical Field

[0001] The utility model relates to the technical field of bridge prefabricated component manufacturing, in particular to a double-jack demoulding device for a prefabricated T-beam hydraulic template diaphragm. Background Art

[0002] Prefabricated bridge construction requires T-beams, which are fabricated at the prefabrication site and then transported to the bridge's locking area for erection. Existing T-beams are cast in T-beam molds, which are then manually disassembled by hammering. This manual demolding process is laborious and inefficient. Utility Model Content

[0003] The utility model aims to provide a prefabricated T-beam hydraulic template diaphragm double-jack demoulding device for opening a T-beam mold, which solves the problem of laborious manual mold opening in the prior art.

[0004] To achieve the above objectives, the present invention employs the following technology: a prefabricated T-beam hydraulic formwork diaphragm double-jack demolding device, characterized by comprising T-beam molds located on both sides of the prefabricated T-beam and a mold disassembly mechanism. The T-beam molds include a formwork that shapes the T-beam surface during casting and a support frame that supports the formwork. The mold disassembly mechanism includes a slide rail extending along the extension direction of the T-beam, a mobile frame slidably connected to the slide rails, a support base slidably connected to the mobile frame along the width of the T-beam on a guide rail, and a mold-opening hydraulic cylinder mounted on the mobile frame that drives the support base to slide. The support base is configured to support the support base so that it moves with the support base. During use, the T-beam is cast using the T-beam mold, and then the support base is driven by the hydraulic cylinder to move away from the T-beam. The movement of the support base drives the T-beam mold to separate from the T-beam, thereby achieving demolding. After demolding, the mobile frame is moved to remove the present invention. The compact structure allows for quick and convenient demolding.

[0005] Preferably, the support brackets on both sides of the T-beam are sleeved on both ends of the cross-tie rod, and the ends of the cross-tie rod are threadedly connected with anti-slip nuts to prevent the support brackets from separating. It can be seen that the force applied after the T-beam mold is closed is more reliable, and it is not easy to separate.

[0006] Preferably, the T-beam includes a vertical plate and a panel connected to the upper end of the vertical plate. The formwork includes a panel side panel for shaping the side surfaces of the panel, a panel lower surface panel for shaping the lower surface of the panel, and a vertical plate for shaping the side surfaces of the lower vertical plate. The panel side panel and the panel lower surface panel are detachably connected together, the panel side panel being disconnected from the support frame, while the panel lower surface panel is connected to the support frame. During demolding, the panel side panel is first removed, and then the remaining formwork is removed by the support frame moving along with the movable frame. This allows for demolding in an oblique downward manner, which is labor-saving, reliable, and less likely to damage the T-beam surface.

[0007] Preferably, the system further comprises a plurality of open rings, one end of each of which is provided with a threaded through hole, a push pin being threadedly connected to the threaded through hole, the panel side plate extending outward from the panel to form a panel side plate protrusion, the lower end of the panel lower surface plate being provided with an outer flange, the outer flange being supported on the panel side plate protrusion, the open rings being distributed along the extension direction of the T-beam, the open rings being sleeved on the outer flange and the panel side plate protrusion, the push pin cooperating with the other end of the open ring to press the outer flange and the panel side plate protrusion together, making the detachable connection between the panel side plate and the panel lower surface plate convenient and reliable.

[0008] Preferably, the ejector pin is located above the outer flange and is not easily loosened.

[0009] Preferably, a plurality of vertically extending reinforcing ribs are provided on the outer surface of the panel side plate, and the lower ends of the reinforcing ribs are fixed to the outer flange, so as to improve the strength of the panel side plate and prevent it from deforming easily when subjected to cantilever beam stress.

[0010] Preferably, the support frame is connected to the support seat via a lifting cylinder.

[0011] Preferably, the guide rail is tilted, with one end of the guide rail facing the T-beam being higher and the other end being lower, and one end of the mold opening hydraulic cylinder is hinged to the support seat and the other end is hinged to the movable frame, thereby realizing tilted downward support, saving effort during demoulding and preventing damage to the T-beam.

[0012] Beneficial effect: The mold can be opened automatically, which saves effort and is quick. BRIEF DESCRIPTION OF THE DRAWINGS
