A kind of turning curve guide rail and design method thereof

Abstract

The invention provides a turning curve guide rail. The turning curve guide rail is used for low speed passing of multiple wheel pairs of equipment to achieve turning and comprises an inner side track and an outer side track. The turning curve guide rail is characterized in that an inner side trajectory of the inner side track is a helical segment which is equally divided into two symmetrical arcs, each arc is composed of multiple circular arcs of which the radii are decreased continuously and circular arcs which are connected with the above-mentioned circular arcs in a smooth mode and have the continuously increased radii, and an outer side trajectory of the outer side track is an average line of moving trajectories of the wheel pairs. The turning curve guide rail can effectively decrease the turning radius of a quay crane, the laying length and occupied area of a turning track of the quay crane are decreased, on one hand, stable turning of the quay crane is promoted, and on the other hand, a quay crane lateral displacement mechanism is avoided. On the premise that the safety is guaranteed, light weight of the quay crane is achieved, the purposes of saving materials of the quay crane and track mechanism, reducing power consumption and reducing the harbor quay crane cost are achieved, and therefore the good social and economical benefits are achieved.

Description

technical field [0001] The design of the invention belongs to the traffic and transportation road engineering, and in particular relates to a turning curve guide rail and a design method of the guide rail for the transportation equipment with multiple wheel pairs to pass through at low speed to realize turning. Background technique [0002] The orientation change of the guide rail route is the cornering, which is usually realized through arc-shaped bends. However, quay cranes (also known as quayside container cranes and bridge cranes, which are equipment used to load and unload containers on ships on the shore), yard bridges (bridge-type handling equipment used in the storage area, used for infield handling) ) and other transportation and lifting equipment with multiple wheel pairs when cornering, due to the misalignment and track errors of the outer wheel tracks, the current quay cranes often use the entire section of large-radius arcs in the curve design to reduce the Tra...

Problems solved by technology

[0003] In order to solve the above-mentioned problem that the arc radius of the turning track is too large or too small, the present invention proposes a turning curve guide rail and its design method, which can effectively reduce the turning radius of the quay bridge , so as to reduce the laying length and floor area of ​​the quay crane's curved track. On the one hand, it is beneficial to the quay crane's smooth turning and reduces the occurrence of "rail-gnawing" phenomenon.
