Problems solved by technology

[0002] In the prior art, since the horizontal wheel of the ring crane is generally installed at the lower part of the main girder, the distance between the two main girders cannot be too large due to the layout requirements, resulting in a small wheel base of the horizontal guide mechanism, and the horizontal wheel bears too much pressure during the movement of the crane. , its "running roundness" is not good, the operation is unstable, and the horizontal wheel is easily damaged, which cannot meet the development needs of large-scale nuclear power machinery

Embodiment Construction

[0032] Such as Figure 1 to Figure 4 The large wheelbase horizontal guide mechanism for the ring crane shown is composed of four corner horizontal guide mechanisms respectively arranged on the four corners of the horizontal plane of the ring crane to realize horizontal guidance through the joint action;

[0033] Each corner horizontal guide mechanism includes: horizontal support 2.1, horizontal guide wheel 2.3, oblique support 2.4 and support rod 2.5;

[0034] The support rod 2.5 is the main load-bearing part and is a long rod part. The horizontal guide wheel 2.3 is installed on the head, and the root is fixed under the side of the main girder 1 of the bridge frame of the ring crane. The support rod 2.5 firmly supports the horizontal guide wheel 2.3 on the main girder of the bridge frame. Outer 1 side, and the support rod 2.5 extends outward relative to the side wall of the ring crane bridge girder 1 from the root to the head;

[0035] The oblique support 2.4 is a supporting ...

Abstract

The invention discloses a large-wheel tread horizontal guide mechanism for a circuiting crane. The large-wheel tread horizontal guide mechanism for the circuiting crane is composed of four corner horizontal guide mechanisms which are arranged at four corners of the horizontal plane of the circuiting crane and realizes horizontal guidance by virtue of a joint action. Each of the corner horizontal guide mechanisms comprises a horizontal support, a horizontal guide wheel, an oblique support and a supporting rod, wherein the oblique support, the supporting rod and a bridge girder of the circuiting crane are assembled to form a longitudinal oblique triangular structure; the horizontal support, the supporting rod and the bridge girder of the circuiting crane are assembled to form a horizontal oblique triangular structure. The front end of the supporting rod extends in a divergent manner relative to the bridge girder of the circuiting crane, and the horizontal guide wheel is assembled on the front end part of the supporting rod to realize a large wheel tread of the horizontal guide wheels.

Description

technical field [0001] The invention relates to a horizontal guide mechanism of a ring crane for lifting dangerous loads in a nuclear power plant, in particular to a horizontal guide mechanism with a large wheel base for the ring crane. Background technique [0002] In the prior art, since the horizontal wheel of the ring crane is generally installed at the lower part of the main girder, the distance between the two main girders cannot be too large due to the layout requirements, resulting in a small wheel base of the horizontal guide mechanism, and the horizontal wheel bears too much pressure during the movement of the crane. , its "running roundness" is not good, the operation is unstable, and the horizontal wheel is easily damaged, which cannot meet the development needs of large-scale nuclear power machinery. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a large wheelbase horizontal guide mechanism for ring cr...
