Description

Technical Field

[0001] This invention relates to an adjustable sealing device for wheel tracks. Background Technology

[0002] In some spatial areas with tracks, it is necessary to divide the space into isolated sections under certain circumstances. Therefore, the tracks need to be sealed so that the space through which the tracks pass can be isolated into independent spaces. In cases where the space does not need to be sealed, when a device traveling on the track passes by, the track needs to maintain its functionality, and the sealing device needs to be released so that the wheels or trolleys of the device can travel smoothly without interference or obstruction.

[0024] For general-purpose railway tracks, when using them, the irregular shapes of the track waist and the gaps at the bottom should be pre-filled with resin or a material that can be bonded to the track waist to ensure that the contact surface of the sealing device is flat.

[0025] As a further improvement of the present invention, the outer end side of the wheel track sealing block 6 and the inward side of the outer side plate 4 form an inclined surface 12. The vertical distance between the bottom end of the inclined surface 12 and the wheel track 7 is greater than the vertical distance between the top end of the inclined surface 12 and the wheel track 7. The angle between the inclined surface 12 and the vertical surface in the front-back direction is 1°-5°.

[0026] As a further improvement of the present invention, the above-mentioned driving element 5 is a cylinder, a hydraulic cylinder or an electric cylinder, and the number of driving elements 5 is 2 to 6. The driving part of each driving element 5 is fixedly connected to the lower part of the wheel track sealing block 6.

[0027] As a further improvement of the present invention, the base plate 1 is rectangular and located horizontally.

At this time, the adjustable sealing device completes the sealing of the wheel track 7. When it is necessary to release the seal, the driving part of the driving element 5 drives the wheel track sealing block 6 to retract, and the wheel track sealing block 6 enters the cavity formed by the bottom plate 1, the outer side plate 4, the front side plate 2, and the rear side plate 3. The space left on both sides of the wheel track 7 above it is used to allow the passage of track balance wheels, trolleys, or other traveling devices. Therefore, the wheel track adjustable sealing device of the present invention has the characteristics of simple and compact structure, excellent sealing effect, easy operation, and quick switching to maintain or release the sealing state.
