Description

A kind of novel bridge retractor device sliding case

Technical field

This utility model belongs to Highway bridge technique field, especially relates to a novel bridge retractor device sliding case。

Background technology

Along with the fast development of highway transportation, traffic volume of highway and carload lot are also increasing, the properties of Expansion Units for Highway Bridges is had higher requirement by this。Vehicular load, as the most important load-bearing of modular expansion device, displacement component, will be quickly delivered in bridge structure the sliding parts going to and protecting inside by sliding case, and it reasonably designs the service life that can be greatly improved retractor device。Present most of sliding case is all form with Plate Welding, and the welding deformation in welding process can reduce the dimensional accuracy of box house, affects the assembly precision of flexible member, thus affecting the service life of displacement system；And welding quality not easily ensures, if the concrete placings of box bottom is unreal, the situation that sliding case snaps at weld often occurs under the repeated action of vehicular load, has a strong impact on the service life of retractor device。The seat of spiral shell up and down inside sliding case is used for fixing control spring pressing plate, fixed form is improper, there will be come off, situation of movement, thus affecting the displacement function of retractor device, and in the retractor device of oblique, often occur that upper and lower spiral shell seat location is improper and cause control spring pressing plate and central sill to produce situation about interfering。

In order to prior art is improved, people have carried out long-term exploration, it is proposed that various solutions。Such as, Chinese patent literature discloses a kind of bridge extension joint [application number: CN201320641260.8], welded square tube including the rectangular shape of cross section of two both ends opens, it is fixed on the pin of welded square tube both sides, support beam, the side bar shaped steel that two are oppositely arranged, it is fixed on the central sill shaped steel supported above beam, the two ends of described support beam are plugged in the endoporus of welded square tube respectively, the edge of a wing of side bar shaped steel it is welded in inside described welded square tube, the lower end of side bar shaped steel is fixed in shear spring upper end, the upper end supporting beam is fixed in shear spring lower end, support spring to be arranged between support beam and welded square tube。

Although such scheme to some extent solves the deficiencies in the prior art, but spiral shell seat is used for fixing control spring pressing plate up and down, fixed form is improper, there will be come off, situation of movement, thus affecting the displacement function of retractor device, and in the retractor device of oblique, often occur that upper and lower spiral shell seat location is improper and cause control spring pressing plate and central sill to produce situation about interfering, global design is reasonable not enough。
