Problems solved by technology

At present, most of the existing quay bridge structures in the port have deficiencies in the seismic design. The main consideration is the influence of the quay bridge lifting load, self-weight load, wind load and dynamic load on the quay bridge structure, while the dynamics of the quay bridge structure under seismic loads. ill thought out response
Relevant studies have shown that when the quay bridge is in the non-working anchored state, when it encounters the excitation of seismic waves along the direction of the wharf cart track, the structure of the whole machine will produce a displacement parallel to the direction of the cart track. Generally, wharf users consider the positioning deviation of the crane equipment to stop , the size and length of the ground anchor pit in the direction of the cart running is relatively large, and there will still be a certain gap when the anchor pin

Abstract

The invention provides a port machinery windproof anchoring device capable of compensating seismic motion. The port machinery windproof anchoring device comprises an anchoring support fixed with an anchoring beam in a cart steel structure, and an anchor pin assembled on the anchoring support, wherein the bottom of the anchor pin can extend downwards to be embedded into an anchoring pit preset in the ground in a matched mode to achieve limiting, a driving mechanism for driving the anchor pin to move up and down is arranged on the anchoring support, an anchor pin shearing plate is arranged on the lower part of the anchoring support and located at the up-down stroke position of the anchor pin, a through hole for the pin rod part of the anchor pin to extend downwards is formed in the anchor pin shearing plate, and the strength of the anchor pin shearing plate is weaker than that of the anchor pin. According to the port machinery windproof anchoring device, the displacement influence of the ground or the structure caused by the seismic load perpendicular to the cart direction can be released, the whole machine is prevented from overturning or the structure is prevented from being damaged, and the safety of harbor equipment and personnel safety of a seismic zone are improved.

Description

technical field [0001] The invention relates to the technical field of loading and unloading equipment at ports and wharves, in particular to a windproof anchoring device for shoreside container cranes. Background technique [0002] Shore-to-shore container cranes (referred to as quayside cranes) are important super-large equipment for port operations. In order to better meet the development requirements of the shipping industry, container cranes are increasingly large, high-speed, and intelligent, and their lifespan has been extended. Energy consumption is gradually increasing. decrease, and the requirements for its safety are getting higher and higher. Affected by special locations such as ports and wharves, strong winds are often encountered, and incidents of port cranes slipping or even overturning under the influence of typhoons have occurred from time to time. The problem of wind protection for port cranes has attracted much attention. Windproof measures are also indi...
