Problems solved by technology

[0002] For building construction, we often encounter some road and bridge construction operations, which will encounter the construction and maintenance of tunnels or door openings, and when it comes to such construction operations, we often use a load-bearing system for facilities such as tunnels or door openings. As the support and protection of the facility, the general method is to set up a lifting bracket under the door opening that needs to be lifted, but this method is cumbersome, and the workload is large, the construction period is long, and a lot of manpower will be wasted. material resources
[0003] In order to solve the problem of erecting a jacking bracket under a door opening that needs to be jacked up, but this method is cumbersome, and the workload is large, the construction period is long, and a lot of manpower and material resources will be wasted. The Chinese invention CN 205421023 U discloses a road bridge The supporting device includes a base, a groove is provided on the base, a hydraulic cylinder is provided in the groove, a column is provided on the top of the hydraulic cylinder, a lifting platform is sleeved on the column, and the lower surface of the lifting platform is Both sides are connected to the surface of the base through hydraulic lifting columns. The lifting platform is provided with a support frame and a pair of semi-arc-shaped outsourcing steel plates. The two outsourcing steel plates are butted on the columns. The connecting plate that is butted with the outer cladding steel plate, the connecting plate is fixed by bolts, the outer side of the outer cladding steel plate is welded with a fixing plate, and the lower surface of the fixing plate is connected to the support frame
The reinforcing plate is provided with a hydraulic jack; the present invention is simple in structure, easy to manufacture, and convenient for the construction of the bridge; however, since the supporting surface of the device is fixed, the supporting area with the bridge cannot be increased as required, and it is necessary to carry out Multiple supports at the same time are time-consuming and labor-intensive; the device cannot be moved, and it is troublesome to determine its position, time-consuming and labor-intensive

Abstract

The invention discloses a bridge bracing device with the bracing surface capable of being enlarged. The bridge bracing device comprises a base. A first sliding rail and a supporting plate are arranged at the top of the base. The base is provided with fixing devices. A rotation lifting device is arranged at the top of the supporting plate. Each fixing device is composed of a rotating handle, a first threaded rod and a fixing base. The rotation lifting device is composed of a device shell, a bearing, a second threaded rod, a sleeve, a connecting shaft, a second limiting plate, a driven wheel, a driving wheel and a driving motor. The bridge bracing device is simple in structure, reasonable in design and convenient to use, and the labor force of workers is saved. Moreover, the bridge construction speed is increased, and the bracing device can be used repeatedly. Due to the arrangement of universal wheels, the bracing device can be moved conveniently. Through arrangement of the fixing devices, the bracing device can be fixed, and meanwhile the service life of the universal wheels can be prolonged. Due to arrangement of a second fixing plate, the bracing surface of a bridge by the bracing device can be enlarged, and the bracing surface of the bridge can be made wider.

Description

technical field [0001] The invention relates to a bridge supporting device, in particular to a bridge supporting device capable of expanding the supporting surface. Background technique [0002] For building construction, we often encounter some road and bridge construction operations, which will encounter the construction and maintenance of tunnels or door openings, and when it comes to such construction operations, we often use a load-bearing system for facilities such as tunnels or door openings. As the support and protection of the facility, the general method is to set up a lifting bracket under the door opening that needs to be lifted, but this method is cumbersome, and the workload is large, the construction period is long, and a lot of manpower will be wasted. physical resources. [0003] In order to solve the problem of erecting a jacking bracket under a door opening that needs to be jacked up, but this method is cumbersome, and the workload is large, the construct...
