Description

Technical Field

[0001] This invention relates to the field of guide wheel device technology, and in particular to a bidirectional adjustable eccentric guide wheel device. Background Technology

[0002] When a marine lifting device is vertically lifting, it can withstand a certain off-center load moment through the full contact between the guide wheels and the guide rails of the lifting platform. In particular, after long-term use, due to the deformation of the hull causing slight changes in the position of the guide rails, or due to wear of the guide rails after long-term use, the guide wheels and guide rails may not be able to make full contact or may become stuck, resulting in unstable operation of the lifting platform. In such cases, the guide wheel device needs to be replaced. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the present invention provides a bidirectional adjustable eccentric guide wheel device, which can simultaneously withstand forces in two vertical directions. This not only makes the guide wheel device compact and easy to install, but also allows for fine adjustment of the circumferential position of the guide wheel in two directions through two eccentric shafts, so as to adapt to wear or slight deformation caused by long-term use of the guide rail, ensuring full contact and pressure transmission between the guide wheel and the guide rail, and ensuring the stability of equipment operation. At the same time, the bidirectional adjustable eccentric guide wheel device can withstand overturning moments in two vertical directions when mirror-mounted in pairs and used in conjunction with corresponding guide rails.

[0030] This invention provides a bidirectional adjustable eccentric guide wheel device, comprising: a guide wheel mounting frame 1, a transverse guide wheel assembly 2, and a longitudinal guide wheel assembly 3, wherein...

[0031] The upper surface of the flange of the guide wheel mounting bracket 1 is provided with a protrusion, and the protrusion is provided with a tapered hole along the width direction of the flange. The tapered hole is adapted to the tapered shaft 6 of the transverse guide wheel assembly 2.

The circular shaft hole is adapted to the small shaft of the eccentric shaft 14 of the longitudinal guide wheel assembly 3 and is used to install and fix the longitudinal guide wheel assembly 3.

[0032] The tapered shaft 6 of the transverse guide wheel assembly 2 passes through the tapered hole, and the small shaft end of the tapered shaft 6 is pressed onto the guide wheel mounting bracket 1 in sequence by the adjusting sleeve 9, the small shaft end stop washer 10 and the small shaft end nut 11;

[0035] Meanwhile, an oil cup 4 is installed on the lug of the guide wheel mounting bracket 1, and the oil cup 4 is connected to the lubrication channel inside the longitudinal guide wheel assembly 3 through the lubrication channel provided on the lug.

The small shafts on both sides of the eccentric shaft 14 are concentric, and the eccentricity between the concentric shaft and the center line of the mounting shaft of the longitudinal guide wheel 13 in the middle section is e (determined according to actual adjustment requirements). By rotating the eccentric shaft 14 in the circumferential direction, the longitudinal guide wheel 13 can be adjusted to a position of twice the eccentricity e in the circumferential direction.

[0046] This bidirectional adjustable eccentric guide wheel device can be formed by mirroring the longitudinal guide wheel assembly 3 along the central axis of the transverse guide wheel assembly 2 to create a pairable bidirectional adjustable eccentric guide wheel device.
