Embodiment Construction
[0019] The present invention will be further explained in conjunction with the drawings.
[0020] A maintenance device for ballastless track slabs, such as figure 1 As shown,
[0021] A maintenance device for a ballastless track plate. The maintenance device for a ballastless track plate includes a handle 1, a top cover 2, a piston rod 3, a rubber sleeve 4, a piston 5, a pressure infusion device shell 6, a plastic catheter 8, and an injection needle tube 9.
[0022] The rubber sleeve 4 is wrapped on the piston 5, and one end of the piston rod 3 is fixedly connected with the piston 5;
[0023] The piston 5 is placed in the pressure infusion device shell 6, and the top cover 2 and the pressure infusion device shell 6 are tongue-and-groove connected.
[0024] The other end of the piston rod 3 is screwed and fixed with the pressure handle 7.
[0025] One end of the plastic tube 8 is connected with the outlet of the pressure infusion device 6, and the other end is connected with the end a of ...

Abstract
The invention discloses a ballastless track slab maintenance device and relates to a ballastless track slab maintenance device in track transit. The ballastless track slab maintenance device is suitable for being applied to the maintenance of damages such as cracking, holes and chipping and the like of ballastless track slabs. The device provided by the invention can be used for overcoming the defects that the damages of the existing ballastless track slab can not be completely filled, gaps exist, the repair speed is slow, the quality can not be easily ensured, and machines and tools are complicated. The ballastless track slab maintenance device comprises a pressure perfusion apparatus (6), a plastic conduit (8) and an injection needle tube (9), wherein one end of the plastic conduit (8) is connected with the outlet of the pressure perfusion apparatus (6), and the other end of the plastic conduit (8) is connected with the end a of the injection needle tube (9). The outer diameter of the injection needle tube (9) is selected according to the damage situations. When the perfusion apparatus is used, because the injection needle tube can be deeply inserted into gaps and simultaneously provide a certain injection pressure, the gaps and damage parts can be filled densely, thereby accelerating the repair speed; and the ballastless track slab maintenance device can be operated by a single person, thereby saving the device addition and labor cost.
Description
Technical field [0001] The invention relates to a maintenance device for ballastless track slabs of rail transit. It is suitable for the repair of cracks, holes, falling blocks and other diseases of ballastless track slabs. Background technique [0002] Ballastless track is an important part of rail transit structure. The disadvantages of ballastless track structure are: [0003] 1. In the long-term operation process, the ballastless track slab is easy to chip and peel off (pulverization), and at the same time cracks and separation between the mortar cushion and the track slab; [0004] 2. Ballastless track slab damage is difficult to repair. Usually, epoxy resin, polyurethane, etc. are used according to the purpose of repair and cracks. Usually, cracks, peelings, and gaps are repaired by gravity guide rods. This method is difficult to fully enrich the defects of the ballastless track slab, there are gaps, the repair speed is slow, the quality is not easy to guarantee, and the mach...
