Embodiment Construction

[0019] The structure of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] combine Figure 5 to Figure 7 can be seen. 1 is the main line rail, 2 is the sleeper, and 3 is the guard rail. A number of crimping fixture units are arranged between the rail bottoms of the two guard rails between the sleepers. The pinch plate 5 and the rigid connecting rod 8 connected by the bottom plate. A crimping fixture is installed at the bottom of the guard rail between the sleepers, and the crimping fixture is composed of three parts: a base plate 4, a buckle plate 5, and a coupling mechanism. Depend on Figure 7 It can be seen that firstly the base plate 4 and the pinch plate 5 are combined and buckled on the bottom of the guard rail, and then the nut 7 is tightened after the stud bolt 6 passes through the reserved middle hole of the base plate 4 and the pinch plate 5 from the bottom. The gusset plate is provided with two...

Abstract

The invention relates to a stability strengthening structure of a continuously welded rail on a bridge. The transversal stability of the continuously welded rail on the bridge is increased. A plurality of withholding clamp units are arranged between the rail bottoms of two guard rails among sleepers, and each withholding clamp unit comprises a bottom plate 4 fixedly connected with the guard rails, a buckling plate 5 connected with the bottom plate, and a rigid connecting rod 8. The rigid connecting rods are obliquely connected between the buckling plates of the units. The strengthening structure is installed between the guard rails and cannot disturb a track bed. The flexural rigidity of the guard rails is fully utilized, the whole flexural rigidity of a track frame is increased, and the stability of the continuously welded rail is obviously improved. The track structure style is improved, the influence from parameter variance is lower, and the strengthening structure has the advantages of convenience in installation and disassembly and no influence on maintenance and repair work.

Description

technical field [0001] The invention belongs to the technical field of railway rails, in particular to the technical field of seamless track stability control. Background technique [0002] The seamless line connects all the steel rails laid on the line into a long rail by welding, so that the train can run safely and smoothly on the line. Different from laying the seamless track on the ground, the beam body of the seamless track on the bridge will elongate and deform under the action of temperature. additional pressure, such as figure 1 As shown, especially in the rails at bridge girder joints, additional pressure peaks F f , which increases the risk of stability failure of the seamless line on the bridge in high temperature seasons, and it is necessary to strengthen the stability of the seamless line on the bridge. [0003] The phenomenon of damage to the stability of the seamless track is that the steel rail undergoes excessive lateral displacement and deformation unde...
