Description
Technical Field
The utility model belongs to the technical field of bridge construction, and particularly relates to a bridge temporary support dismantling device which is an operation device required by bridge temporary support dismantling operation after system conversion is completed in a highway simply supported and continuous beam construction process.
Background
The simply-supported-and-continuous beam bridge has the advantages of low cost, high construction speed, simple process and the like, and is widely applied to the field of highway engineering construction. The common forms of the bridge superstructure comprise a prestressed box girder, a T girder, a plate girder and the like, a temporary support is firstly adopted for supporting during the installation of a beam slab, and the temporary support is dismantled after the system conversion is completed.
When in site construction, the construction of the cross beam at the upper part of the bridge, the wet joint, the bridge deck guardrail and the like is completed, namely, after the conversion of the bridge system is completed, constructors cannot directly dismantle the temporary support from the bridge deck to the capping beam top. In the prior art, the temporary support dismantling construction is usually carried out by means of a lift truck or a scaffold erected under a bridge, the efficiency is low, the cost is high, and the condition of passing the lift truck or the scaffold erected under the bridge is not provided sometimes, so that the temporary support dismantling is a construction problem existing at present after simply supporting the continuous beam bridge.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a bridge temporary support dismantling device, aiming at the construction difficulty that a temporary support is dismantled after a continuous beam bridge system is converted after simple support.
The technical scheme adopted by the utility model for achieving the purpose is as follows:
a bridge temporary support dismantling device is arranged by attaching to a bridge floor guardrail; the device for dismantling the ladder is composed of two groups of walking systems, two groups of crawling ladders and an operation platform; the walking system is arranged on the bridge floor guardrail; the walking rack of the walking system is supported on the bridge floor guardrail through the vertical rod; two adjacent vertical rods are connected through a cross rod; the lower part of the walking rack and the vertical rod are both provided with walking pulleys with limiting function; the top surface of the walking rack is provided with a winch, a traction rope of the winch sags through a vertical rod outside a pedestal guardrail, and the lower end of the traction rope is connected with the operation platform through a hanging ring; the operation platform is located the bridge floor below, and the platform both ends extend to the bridge floor both sides respectively to connect a cat ladder respectively.
The walking pulleys on the vertical rods face the bridge floor guardrail.
The bridge temporary support dismantling device provided by the utility model is simple in structure, convenient to machine and assemble, capable of completing the temporary support dismantling work without large-scale mechanical equipment, and obvious in economic benefit.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes technical solutions clearly and completely in combination with the embodiments of the present invention. This embodiment is a part of the embodiment of the present invention, and not all embodiments. Other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.
As shown in fig. 1-4, a bridge temporary support dismantling device is arranged attached to a bridge deck guardrail; the device for dismantling the ladder is composed of two groups of walking systems, two groups of crawling ladders and an operation platform; the walking system is arranged on the bridge floor guardrail 6; the walking rack 2 of the walking system is supported on a bridge floor guardrail 6 through a vertical rod 7; two adjacent vertical rods 7 are connected through a cross rod 8; the lower part of the walking rack and the vertical rod are both provided with walking pulleys 3 with limiting function; the top surface of the walking rack is provided with a winch 1, a traction rope of the winch 1 sags through a vertical rod outside a guardrail of the pedestal, and the lower end of the traction rope is connected with the operation platform through a hanging ring; the operation platform is located the bridge floor below, and the platform both ends extend to the bridge floor both sides respectively to connect a cat ladder 4 respectively.
The walking pulleys on the vertical rods face the bridge floor guardrail.
The ladder stand is made of a flexible chain and a steel pipe, and the operation platform and the traveling system rack are all made of profile steel by welding; when the utility model is used, 2 traveling systems are symmetrically arranged on the guardrails at two sides of the bridge floor respectively and are connected with the crawling ladder through the hanging rings respectively.
When the device is used, the assembly of the operation platform is completed at the bottom of the bridge, the walking system is moved to the position to be constructed, then the walking device is fixed, and then the traction rope is put down to lift the operation platform to a proper height. Constructors can carry out the dismantling operation of the temporary support in the operation platform through the crawling ladder 4 from the guardrail.
After the operation is finished, the constructor returns to the bridge floor along the crawling ladder, the winch transfers the operation platform to the ground, the traction rope is removed from being connected with the operation platform, and then the moving device is moved to the next operation point for construction.
