Abstract
A bridge expansion device comprises a sleeve and a sleeve rod. One side of the surface of the sleeve and one side of the surface of the sleeve rod are provided with columns which are connected by two telescopic rods, springs are connected to the telescopic rods in a sleeving way, and sliding blocks are arranged on the top ends of the two columns. The bridge expansion device also comprises two support plates of which the end bottoms are provided with chutes, the two sliding blocks are arranged in the two chutes, support bars are arranged on the upper ends of the inner sides of the two columns, one end of each support bar is provided with a roller which is arranged in the corresponding chute, the opposite ends of the two support plates are provided with a groove and a bulge matched with the groove, an ejection spring is embedded in the groove, one end of the ejection spring is connected with the bulge, and a rubber dust shield is arranged on the surfaces of the support plates. The bridge expansion device is simple and easy to use, high in practicability, low in production cost, and capable of meeting the deformation requirement of a bridge under different circumstances.
Description
Technical field
The present invention relates to a kind of bridge extension joint.
Background technology
In science of bridge building, in order to ensure concrete shrinkage or the stretching that bridge structure causes under normal operating condition due to variations in temperature, load change or concrete creep, need to arrange gap between the girder of bridge, between girder and abutment or between girder and parados, and expansion joint or retractor device are installed in these gaps, so that bridge structure is free to deformation, thus ensure on it vehicle smoothly through.Existing seam retractor device manufactures loaded down with trivial details, and waterproof effect is poor, and price comparison is expensive.
Summary of the invention
It is an object of the invention to for above-mentioned deficiency, it is provided that a kind of bridge extension joint.
Described purpose is achieved by the following scheme:
A kind of bridge extension joint, including sleeve and loop bar, the side, surface of described sleeve and loop bar is equipped with column, two columns are connected by two expansion links, it is socketed with spring on described expansion link, the top of two columns is equipped with slide block, also include two pieces of gripper shoes, described two pieces of gripper shoe bottoms are equipped with chute, two slide blocks are respectively provided in two chutes, said two column inner top side is respectively equipped with support bar, described support bar one end is provided with pulley, described pulley is located in chute, the opposite end head of described two pieces of gripper shoes is respectively equipped with groove and the projection matched, top spring it is inlaid with in described groove, spring one end, described top connection bump.
Described gripper shoe surface is provided with rubber dust-proof plate.
Being provided with the top spring a supporting loop bar in described sleeve, the bottom of described sleeve and loop bar is provided with road wheel.
The present invention has easy to use, practical, and cost of manufacture is cheap, it is possible to adapt to bridge deformation needs in varied situations.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein, 1-sleeve, 2-loop bar, 3-column, 4-expansion link, 5-spring, 6-slide block, 7-gripper shoe, 8-chute, 9-support bar, 10-pulley, 11-groove, 12-is protruding, and 13-pushes up spring, 14-dust excluding plate, and 15-pushes up spring a, 16-road wheel.
Detailed description of the invention
Elaborate the preferred embodiment of the present invention below in conjunction with the accompanying drawings.
A kind of bridge extension joint, including sleeve and loop bar, the side, surface of described sleeve 1 and loop bar 2 is equipped with column 3, two columns 3 are connected by two expansion links 4, it is socketed with spring 5 on described expansion link 4, the top of two columns 3 is equipped with slide block 6, also include two pieces of gripper shoes 7, described two pieces of gripper shoe 7 bottoms are equipped with chute 8, two slide blocks 6 are respectively provided in two chutes 8, said two column 3 inner top side is respectively equipped with support bar 9, described support bar 9 one end is provided with pulley 10, described pulley 10 is located in chute 8, the opposite end head of described two pieces of gripper shoes 7 is respectively equipped with groove 11 and the projection 12 matched, top spring 13 it is inlaid with in described groove 11, spring 13 one end, described top connection bump 12.Described gripper shoe 7 surface is provided with rubber dust-proof plate 14.Being provided with the top spring a15 supporting loop bar 2 in described sleeve 1, the bottom of described sleeve 1 and loop bar 2 is provided with road wheel 16.
During use, seam retractor device is placed on the seam crossing of bridge, under different temperature, bridge easily expands with heat and contract with cold, and during thermal expansion, the top spring a in sleeve can be by sleeve and loop bar to two side shiftings by elasticity, road wheel facilitates the movement of sleeve and loop bar, and road wheel is that metal is made.The mobile drive column of sleeve and loop bar is to two side shiftings, simultaneously, spring on column by two columns to both sides support top, expansion link in spring is avoided that spring is bent by resistance, simultaneously, top spring in groove can be by outside for projection support top by elasticity, groove and protruding cooperation also act as the effect of firm gripper shoe, form gripper shoe and pass through chute and slide block to two side shiftings, support bar and pulley on column play the effect supporting gripper shoe, are avoided that gripper shoe is damaged by pressure by the weight of automobile and subsides.Pulley on support bar facilitates the movement of gripper shoe.Pulley and support bar are connected by bearing pin, and pulley is that metal is made.Rubber dust-proof plate plays outside the rainproof effect with dust protection, moreover it is possible to play automobile non-slip, the weight of dispersion automobile, extends the life-span of jointing apparatus.During shrinkage, narrowing of seam crossing, drive column, gripper shoe, sleeve and loop bar all to reclaiming contracting.
Present embodiment does not simply limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the spirit beyond this patent, all it is considered as the equivalent to this patent, all at the protection domain of this patent.
