It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, a method for repairing a floor cloth of a railway vehicle according to the present invention will now be described. A method for repairing a railway vehicle floor cloth comprises measuring the size of a damaged floor cloth 1; covering the damaged floor cloth 1 with the nondestructive floor cloth 2, wherein the size of the nondestructive floor cloth 2 is larger than that of the damaged floor cloth 1; simultaneously cutting the undamaged floor cloth 2 and the damaged floor cloth 1, cutting off the damaged area of the damaged floor cloth 1 to form a to-be-repaired opening, and obtaining a patch 21 with the same size as the damaged area; the patch 21 is installed into the opening to be repaired and fixedly connected to the floor cloth.
Compared with the prior art, the method for repairing the floor cloth of the railway vehicle comprises the steps of firstly measuring the damaged part of the floor cloth to obtain the size of the damaged floor cloth 1, further determining the size of the needed nondestructive floor cloth 2, then covering the nondestructive floor cloth 2 on the damaged floor cloth 1, and simultaneously cutting the nondestructive floor cloth 2 and the damaged floor cloth 1 by using the cutting knife, so that the cut opening to be repaired is completely the same as the formed size of the patch 21, therefore, the patch 21 can be completely and seamlessly spliced into the opening to be repaired and is fixedly connected with the opening to be repaired, and by the method, the floor cloth can be accurately repaired, so that the repaired floor cloth is more attractive, and the repairing effect of the floor cloth is improved.
The damaged part of setting up the floor cloth is impaired floor cloth 1, measures its size after, confirms that the size of harmless floor cloth 2 is greater than the size of impaired floor cloth 1, ensures that harmless floor cloth 2 can cover impaired floor cloth 1 completely, guarantees when cutting impaired floor cloth 1, and harmless floor cloth 2 is enough to be used.
Referring to fig. 1 and 2, as a specific embodiment of the method for repairing a floor cloth of a railway vehicle according to the present invention, before installing a patch 21 in a to-be-repaired opening and fixedly connecting the patch with the floor cloth, an old adhesive layer in the to-be-repaired opening is scooped out, and when a damaged floor cloth is cut off from a floor, a large number of old adhesive layers are left on the floor, in order to ensure that the patch 21 is firmly installed on the floor, the old adhesive layer of the floor is scooped out by using a scoop knife, the surface of the floor is exposed, then adhesive is applied to the floor, and the patch 21 is seamlessly spliced in the to-be-repaired opening, and the patch 21 is fixedly connected with the floor and other remaining floor cloths by the adhesive.
Referring to fig. 1 and 2, as an embodiment of the method for repairing a floor cloth of a railway vehicle according to the present invention, a used adhesive layer is sanded by using sand paper, and most of the used adhesive layer is removed by using a scraper, but a part of the used adhesive layer remains on a floor, so that the remained used adhesive layer is sanded by using sand paper of P60-P80, and the used adhesive layer is completely removed from the floor. The abrasive paper can effectively and quickly remove the old glue layer without damaging the floor.
Referring to fig. 1 and 2, as a specific embodiment of the method for repairing a track vehicle floor cloth according to the present invention, before cutting the undamaged floor cloth 2 and the damaged floor cloth 1, the undamaged floor cloth 2 is fixed by using an adhesive tape, and when the undamaged floor cloth 2 and the damaged floor cloth 1 are cut, in order to ensure that the cut patch 21 and the formed opening to be repaired are completely consistent, the undamaged floor cloth 2 needs to be temporarily fixed, so that the undamaged floor cloth 2 is fixed to another floor cloth by using the adhesive tape, and the undamaged floor cloth 2 does not move or even slightly move during the cutting process. After cutting, the fixing tape is torn off, the patch 21 is taken down, and the damaged floor cloth 1 is taken out to form a to-be-repaired opening.
Referring to fig. 1 and 2, as a specific embodiment of the method for repairing a floor cloth of a railway vehicle according to the present invention, before installing a patch 21 in a to-be-repaired opening, a glue is applied to the inside of the to-be-repaired opening, before installing the patch 21, an old glue layer remaining on the floor is removed, then a glue is applied to the exposed floor and the inner groove surface of the to-be-repaired opening, and the patch 21 is installed in the to-be-repaired opening in a seamless manner and is adhered to the floor and other floor cloths through the glue. The lower end face of the patch 21 is in contact with glue on the floor, and the outer side face of the patch 21 is in contact with glue on the inner groove face of the opening to be repaired, so that the fixing effect of the patch 21 through glue bonding is better.
