Abstract
The utility model belongs to the technical field of a bridge expansion seam, which discloses a special fixed steering mechanism for a bridge expansion device. The utility model has the main technical scheme that the utility model comprises a base seat of which the middle has a groove, and the base seat is fixed to a whole with the bridge expansion device; concentric circular holes are arranged on two walls made up the groove, one end is fixed with a pin shaft connected with a shaft of an expansion mechanism of the expansion device and the other end is provided with a connecting plate clamped in the groove and fixed by a shaft of the concentric circular holes on the two walls. Both ends of the expansion mechanism in a controlling box of the expansion device are fixed with the controlling box body through the steering mechanism of the shaft, therefore the expansion mechanism has the characteristics that the function of the adjustment of longitudinal extension between beam bodies and between the beam bodies and bridge abutments is realized, and the adjusting function of vertical and fan-shaped dislocation between both can also be synchronously realized.
Description
Technical field
The utility model belongs to the bridge expanssion joint technical field, relates to a kind of by the bridge extension joint dedicated fixed steering mechanism that constitutes.
Background technology
Bridge extension joint be fixed between the beam body of bridge, between beam body and the abutment, when producing dislocation between the beam body that causes owing to heat expansion, shrinkage or other reasons and between beam body and the abutment, be used to remedy gap between the two, keep the device of bridge floor vehicle smooth-ride.Constitute between the beam body of bridge, the dislocation between beam body and the abutment comprises vertical dislocation along the bridge floor direction, perpendicular to the vertical dislocation of bridge floor, perpendicular to the transversion malposition and the common fan-shaped dislocation distortion that constitutes of vertical and horizontal of bridge floor direction.At present, the bridge extension joint that generally uses such as the patent No. are ZL01219103.5, notice of authorization number is called a kind of patent of bridge extension joint for the disclosed name of CN2474573Y, because directly being fixed on beam body or abutment, the telescoping mechanism of this bridge extension joint of formation constitutes on the control cabinet of one, therefore this bridge extension joint can only be realized along vertical dislocation of bridge floor direction with perpendicular to the flexible adjustment of the horizontal small dislocation of pontic direction, and can not realize perpendicular to the vertical dislocation of bridge floor with along the flexible adjustment of the common fan-shaped dislocation distortion that constitutes of the vertical and horizontal of bridge floor direction.
The utility model content
The purpose of this utility model just provide a kind of can be between the beam body of bridge and vertical, horizontal, the vertical and fan-shaped dislocation distortion that produces between beam body and the abutment a kind of bridge extension joint dedicated fixed steering mechanism that can adjust.
The technical solution adopted in the utility model is: bridge extension joint dedicated fixed steering mechanism, comprise that the centre that is fixed as one with bridge extension joint is the pedestal of groove, constitute on two walls of this groove and have concentric circle holes, an end is fixed with the bearing pin, the other end that are connected with the telescoping mechanism axle of stretching device and then is fixedly coupled plate for snapping in the described groove by concentric circle holes axle on two walls.
Bridge extension joint dedicated fixed provided by the utility model steering mechanism, since between the two ends of the telescoping mechanism in the stretching device control cabinet and control casing by fixing by a rotation mechanism of two vertical direction, therefore telescoping mechanism is being realized between the beam body and in the function that longitudinal extension is adjusted between beam body and the abutment, is also being had the characteristics that function is adjusted in the two vertical and fan-shaped dislocation of realization.
Description of drawings
Fig. 1 is the structural representation of the utility model bridge extension joint dedicated fixed steering mechanism;
Fig. 2 is for using the fixedly steering mechanism bridge extension joint structural representation of this special use;
Fig. 3 is the A-A cross section structure schematic diagram of Fig. 2.
The specific embodiment
Be described further below in conjunction with the structure of accompanying drawing bridge extension joint dedicated fixed provided by the utility model steering mechanism.
Be illustrated in figure 1 as the structural representation of bridge extension joint dedicated fixed steering mechanism.Comprise the pedestal 1 that the control cabinet with bridge extension joint is fixed as one, have a groove 2 on this pedestal, constitute on two walls 3 of this groove and have concentric circle holes 4, a plate 5 snaps in the groove and is fixing by rotating shaft 6 by inserting on two walls concentric circle holes.The other end of this junction plate is connected with the telescoping mechanism axle of stretching device by fixing with it bearing pin 7.
Be depicted as the bridge extension joint structural representation that has used this dedicated fixed steering mechanism as Fig. 2,3.Promptly comprise and be separately fixed at the control cabinet 9 that left and right two half chests on two beam bodies (or abutment) 8 are formed, side at control cabinet is fixed with supporting traverse structure 10, each is fixed with this dedicated fixed steering mechanism 11 with control casing 9 two ends of opposite side, and the two ends of telescoping mechanism 12 are by 7 connections of the bearing pin on the junction plate.
Operating principle is, when producing vertically between two beam bodies (or abutment), when laterally especially vertical and fan-shaped dislocation is out of shape, then can carrying out the adjustment of three-dimensional by rotating shaft 6 in the fixedly steering mechanism of being fixed in the control cabinet two ends and bearing pin 7.
Claims (1)
1, bridge extension joint dedicated fixed steering mechanism, it is characterized in that: comprise that the centre that is fixed as one with bridge extension joint is the pedestal of groove, constitute on two walls of this groove and have concentric circle holes, an end is fixed with the bearing pin, the other end that are connected with the telescoping mechanism axle of stretching device and then is fixedly coupled plate for snapping in the described groove by concentric circle holes axle on two walls.
