Abstract
The utility model relates to a movable bridge construction support, by fixed bolster, pulley structure, telescopic bracket, the support holder, the down tube, the base, guardrail etc. constitute. The fixed bolster is installed detachable pulley structure, and telescopic bracket is connected to the lower extreme. The telescopic support is provided with a lengthening assembly which is convenient for the construction support to adjust the length, the lengthening assembly is connected with the supporting support and the base, and the base is connected with the telescopic support through an inclined rod. The telescopic support is also provided with a lengthening assembly which is convenient for the construction support to adjust the length. The utility model provides a limited problem of length of construction support when bridge rail guard or crashproof wall outside construction, through scalable elongated construction support for constructor can carry out the operation to bigger region after arranging the construction support after finishing with the extension, thereby reduces constructor and arranges the number of times of construction support, and it is more convenient to let constructor's construction.
Description
Technical Field
The utility model belongs to the technical field of bridge engineering, in particular to movable bridge construction support.
Background
In mountain expressway and city, prestressed concrete continuous rigid frame bridge is used for crossing valley, river and city overhead. Because the service life of the rigid frame bridge is limited, maintenance is required regularly, and nonstandard operation methods may influence the construction quality and the safety of constructors. After bridge engineering construction is accomplished, the construction support is also all demolishd, and later stage if need be when the bridge maintenance, need use construction support or mechanical equipment to carry out supplementary construction, but present most construction support is the fixed point formula, is not convenient for remove, can not remove while being under construction, and it is more troublesome to dismantle after the construction is accomplished in the maintenance simultaneously, great improvement the cost, reduced the efficiency of construction. If mechanical equipment is used for assistance, the defects that the lane is occupied, the mechanical rental cost is high, and the construction cost is greatly improved exist.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a movable bridge construction support, when solving constructor and standing the construction on bridge construction support, the limited problem of length of construction support.
A mobile bridge construction support comprising: the device comprises a fixed support, a pulley structure, a telescopic support, a supporting support, an inclined rod, a base and a guardrail, wherein the fixed support is welded by square steel and is positioned at the top, the middle of the fixed support is connected with the pulley structure, the front end of the fixed support is connected with the telescopic support, the telescopic support is connected with the supporting support and the base, the base is connected with the telescopic support through the inclined rod, and the guardrail is connected with the base; the pulley structure consists of a rubber wheel and a steel frame and is provided with a stop device; the telescopic bracket is formed by connecting a first steel bracket and a second steel bracket with different calibers through a rail, and is fixed by a pin structure group; the inner side of the first steel bracket is formed by welding a plurality of square steels; the outer side of the second steel bracket is formed by welding a plurality of square steels; the supporting bracket consists of two channel steels, and the head part of the supporting bracket is connected with a rubber gasket; the diagonal rod connects a square steel frame of the base with the telescopic support, and the square steel frame of the base is formed by welding a plurality of square steels; the guardrail is of a net structure woven by synthetic fibers; the base and the first steel support are connected through welding by a square steel.
The utility model provides a limited problem of length of construction support when bridge rail guard or crashproof wall outside construction, through scalable elongated construction support for constructor can carry out the operation to bigger region after arranging the construction support after finishing with the extension, thereby reduces constructor and arranges the number of times of construction support, and it is more convenient to let constructor's construction.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description is made in conjunction with the embodiments of the present invention. The following examples are intended to illustrate the invention and are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of a movable bridge construction support, where a fixed support 1 and a pulley structure 2 are connected by a cylindrical rod; the fixed support 1 is connected with the telescopic support 3 in a welding mode; the telescopic bracket 3 is connected with the base 6 in a welding mode; the telescopic bracket 3 is connected with the base 6 by adopting an inclined rod. The guard rail 7 is connected through a hole in the base 6.
Referring to fig. 2, fig. 2 is a schematic view of a local structure of a telescopic bracket, the telescopic bracket is formed by connecting a first bracket 11 and a second bracket 12 through a rail, and fixedly connecting the first bracket 11 and the second bracket 12 through a pin hole 9 and a pin 10, wherein the first bracket 11 and the second bracket 12 are formed by welding two rectangular steels and a plurality of rectangular steels.
Referring to fig. 3, fig. 3 is a schematic partial structure diagram of a pulley structure, where the pulley structure is composed of a guard plate 13, a shaft 14, a pulley 15, and an anti-skid structure 16, and the guard plate 13 and the shaft 14 are connected by a screw thread and are detachable; the shaft 14 and the pulley 15 are connected by bearings. The anti-slip structure 16 is constituted by a pin and a pin hole.
The installation process of the movable construction support is as follows:
firstly, positioning a movable construction support device; secondly, the personnel are in place and start construction; thirdly, after the construction is finished, people leave the movable support; fourthly, moving the construction support, putting personnel in place, starting construction, and so on; and fifthly, withdrawing the construction support.
The present invention is not limited to the above-described examples, and various changes can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art.
