BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin press-in device used for injecting resin into a variable pad in a rail fastening device.

[0002]

2. Description of the Related Art Conventionally, as a resin press-in device of this kind, a suction tube having a ball valve mounted at a lower end suction portion is disposed in a pressure vessel containing a mixed liquid of a resin liquid and a curing agent. ,
A plunger and a rod each having a ball valve attached to the lower end thereof are inserted into the same tube, and the mixed liquid in the tank is sucked into the suction tube by reciprocating the rod. It is configured to inject the mixture into a required location via an adapter mounted on the device.

[0003]

In the conventional resin injector, when the mixed liquid of the resin liquid and the curing agent starts to be cured, the mixed liquid sucked into the suction tube is also cured at the same time. And it becomes impossible to remove,
Use of a resin injector becomes impossible. The present invention has been proposed in view of the problems of the prior art, and its purpose is to allow a mixed liquid of the resin liquid and the curing agent to be pumped by air pressure, and the resin in a pressure vessel. It is an object of the present invention to provide a resin press-in device which can easily remove an unusable resin which has been cured when the resin has been cured.

[0004]

To achieve the above object, a resin press-fitting device according to the present invention comprises a resin tank, an upper lid mounted on an upper end of the tank and provided with an air pressure inlet, The bottom cover has an O-ring on the outer peripheral surface and is provided with a resin supply port at the bottom, and a pneumatic pressure pump connected to an air pressure inlet of the upper lid. I have.

[0005]

Since the resin press-fitting device according to the present invention is constructed as described above, the resin tank is filled with a mixed solution of a resin liquid and a curing agent, and is provided on the upper lid in the resin tank by an air press-fit pump. When high-pressure air is injected through the compressed air inlet, the mixed liquid in the tank is supplied from a resin supply port provided on the bottom cover. At this time, since the O-ring is attached to the outer peripheral surface of the bottom lid, the airtightness between the inner wall surface of the tank and the bottom lid is maintained, and there is no fear that the mixed liquid in the tank leaks.

When the resin starts to harden in the resin tank, the hardened and unusable resin can be removed by removing the bottom cover detachably attached to the tank.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Reference numeral 1 denotes a base, and a support cylinder 2 erected on the base 1
A screw socket 5 which is suspended from a bottom cover 4 which is screwed to the bottom of the resin tank 3 made of an FRP pipe is screwed to the threaded portion. An O-ring 6 for maintaining airtightness with the inner peripheral wall of the tank 3 is mounted on the outer peripheral surface of the bottom cover 4, and a resin supply port 7 is vertically provided.

Reference numeral 8 denotes an upper cover of the tank 3 and an air pressure inlet 9
And a holding bolt 1 screwed into a top horizontal frame piece 11 of a holding frame 10 erected on the base 1.
2 press-fits the upper end opening edge of the tank 3. In the figure, reference numeral 13 denotes a pressure gauge. An air pump 14 is mounted on the base 1 and is connected to the air pressure inlet. Reference numeral 15 denotes a vinyl hose connected to the resin supply port 7, reference numeral 16 denotes a two-way hook interposed in the hose 15, and reference numeral 17 denotes a nozzle.

Since the illustrated embodiment is configured as described above, a release agent for facilitating removal of the cured resin is applied to a portion of the tank 3 to be immersed in the resin before use. , Bottom lid 4 on supporting cylinder 2 of base 1
The screw socket 5 is screwed, the O-ring 6 is attached, the vinyl hose 15 is attached to the resin supply port 7 of the bottom cover 4, and the two-way cock 16 and the nozzle 17 are attached to the tip.

Next, the resin tank 3 is inserted into the bottom cover 4, the tank 3 is filled with a mixture of a resin solution and a hardener, the upper cover 8 is placed on the tank 3, and the holding bolt 12 of the holding frame 10 is held. The upper lid 8 is pressed against the upper open end of the tank 3 by pressing.
An air pump 14 mounted on the base 1 is connected to the air pressure inlet 9 of the upper lid 8, and the air pump 14 is operated to press air into the resin tank 3, and the resin in the tank 3 is cooled by the air. Vinyl hose 15 from resin supply port 7 of bottom lid 4
Feed through.

When the resin in the tank 3 is hardened during the work, the hardened and unusable resin in the tank 3 can be easily removed by removing the bottom cover 4 from the tank 3. it can.

[0012]

According to the present invention, as described above, the upper lid of the resin tank is provided with an air pressure inlet, the lower lid is provided with a resin supply port, and the outer peripheral surface in contact with the inner peripheral wall of the tank is used to maintain airtightness. By mounting the O-ring, the resin in the tank is extruded by air pressure, and the resin injection operation can be easily performed.

[0013] Further, since the bottom cover is detachably attached to the lower end of the resin tank, when the resin is hardened in the tank, the hardened unusable resin can be easily removed by removing the bottom cover. it can. Since the resin press-in device according to the present invention is used for injecting resin into the variable pad for fine adjustment of the rail interposed between the rail and the sleeper in the railway, the number of times of use, the place where the resin press-in device itself is used, and the moving distance Becomes extremely large, and therefore, when the resin in the resin tank is hardened, the work of removing the hardened resin becomes extremely large and requires a quick operation. However, according to the present invention, the bottom cover is provided at the lower end of the resin tank as described above. The resin press-fitting device of the present invention is particularly suitable for injecting resin into the variable pad by fitting the resin detachably.
