Referring to fig. 1 to 3, the present disclosure provides a rubber strip installation device for an expansion joint, including a first traction unit provided with a first winding roller 11 and a second traction unit provided with a second winding roller 21, wherein a clamping member 12 is arranged on a traction rope of the first winding roller 11, the clamping member 12 is used for clamping an expansion belt 72 of a rubber strip in a contraction state, an extrusion member 22 is arranged on a traction rope of the second winding roller 21, and the extrusion member 22 is matched with a large cavity 41 of the expansion joint in shape.

In the prior art, the expansion joint is generally arranged between two ballastless tracks, two adjacent ballastless tracks are close to each other and are all provided with the section bar on one side, two section bars are close to each other and are all provided with the cavity groove on one side, and the rubber strip generally comprises a telescopic belt 72 located in the middle and fixing belts 71 arranged at two ends of the telescopic belt 72, and in the actual construction process, the fixing belts 71 and the cavity groove need to be installed.

Because the chamber groove generally includes big die cavity 41 and the small-size chamber 42 that is close to the rubber strip of keeping away from the rubber strip, so when the installation, generally pack into big die cavity 41 through manual or the mode of pulling with fixed band 71 earlier, and set up extruded article 22 in big die cavity 41, the rethread is pulled extruded article 22 along the length direction at expansion joint, thereby make extruded article 22 extrude fixed band 71, so that fixed band 71 gets into small die cavity 42 from big die cavity 41, because the shape of small die cavity 42 more is for matching with the shape of fixed band 71, therefore fixed band 71 carries out behind the small die cavity 42, the holistic water-proof effects of rubber strip is better.

In the prior art, a worker can only drag the fixing belt 71 and the extrusion part 22 through a common winding roller, the traction equipment is single and is not systematic, and the construction of the next rubber strip can be continued only after the rubber strip of one construction joint is completely installed, so that the construction efficiency is low.

In this embodiment, the system is provided with the rubber strip installation device for the expansion joint, so that the installation efficiency of the rubber strip for the expansion joint is improved.

In the actual construction process, firstly two second hauling ropes are respectively placed in the large cavities 41 of the two profiles, one end of each second hauling rope stretches out of the profile and is connected with the extrusion part 22, and the other end stretches out of the profile and is connected with the winding roller of the second hauling unit.

In some embodiments, the extrusion member 22 has two pairs, and the embodiment further provides a method for installing the rubber strip for the expansion joint, which includes an installation device for the rubber strip for the expansion joint, and further includes the following steps:

step one, arranging a pair of second traction ropes in a large cavity 41 of a first-stage expansion joint, then installing a first traction unit and a second traction unit at the end part of the first-stage expansion joint, drawing a rubber strip into the large cavity 41 of the first-stage expansion joint through the first traction unit, and after the first traction unit finishes drawing, dismantling the first traction unit and constructing the next-stage expansion joint;

Since two pairs of extrusions 22 are provided, only one pair is used, and the remaining pair of extrusions 22 are left idle.

The expansion band 72 can be pulled by the first pulling unit, so that the fixing band 71 runs into the large cavity 41 of the corresponding profile, when the fixing band 71 reaches the design position, namely the large cavity 41, the first pulling unit is not needed for the first expansion joint, and therefore the first pulling unit can be detached, and the first pulling unit is in an idle state at the moment and can be used for construction of the second expansion joint.

In the second step, the first traction unit in the idle state may be installed at the designed position of the second expansion joint, and before the rubber strip at the second expansion joint is pulled, the second traction rope and the extrusion member 22 which are idle in the above steps need to be placed in the section bar corresponding to the second expansion joint in advance.
