Problems solved by technology
Its technical defects are: first, it is difficult to achieve smooth braking
The windproof effect of the wheel brake windproof device is intuitive, and the windproof effect can be seen through the sliding of the wheels or the strong braking of the wheels; 50% of the weight * 0.1 (sliding friction coefficient between the wheel and the rail) wind resistance, can only prevent 6 winds, all-wheel braking, can produce the wind resistance of the whole vehicle weight * 0.1, can prevent 9 winds, not 10 Second, to achieve all-wheel braking, more braking devices need to be added (one set of passive large wheels needs to be added), and the traveling part of the gantry crane has changed a lot, from the perspective of windproof effect and capital investment There is a problem of not matching in terms of aspects, and the cost performance is low
Windproof braking iron shoes have an intuitive windproof effect. Artificial iron shoes require less investment and have a certain cost performance. The technical defect is that the windproof ability is weak. It can be placed on one side of each large wheel. When the wind blows to one side, only 50% of the wheels of the whole car will have the windproof effect, so it can only prevent the wind force of level 6 wind. The windproof ability of the windproof iron shoes is the best of all external windproof equipment. It is a kind of windproof equipment with weak windproof ability; second, if it is artificial iron shoes, it must be installed in advance before the gantry crane is blown by the wind, and it needs two auxiliary personnel to install it at the same time to play a role quickly.
The advantage of the windproof ground anchor is that it has strong windproof ability, has the function of preventing blowing and overturning, and the subsequent maintenance cost is low; Informing relevant personnel and preparing relevant tools cannot meet the problem of immediate use in the face of imminent strong winds. This measure is only suitable for use under the premise of strong wind warnings; technical standards, and the fixed part of the anchor point is mostly buried under the site, which cannot be effectively detected, so there may be a problem of uncertain anchoring force in the actual implementation

The invention discloses a rod type strong wind prevention rail braking system. The rod type strong wind prevention rail braking system comprises a braking unit, and the braking unit mainly comprises abraking rod, a braking frame, a braking oil cylinder and a trapezoidal bolt assembly. The system is small in size, easy to install and small in influence on mechanical properties of a gantry crane, has the characteristics of large wind prevention braking force, stable dynamic braking, simple, convenient and fast braking operation and obvious strong wind prevention braking effect, realizes the wind prevention braking measures for sudden strong wind in the working state of the gantry crane and the aim of strong wind prevention in the non-working state, and effectively achieves the purpose of effectively preventing strong wind for the gantry crane in operation or non-operation.
Description
Technical field [0001] The invention belongs to a windproof brake system of an open-air track gantry crane (hereinafter referred to as a gantry crane), and particularly relates to a rod-type windproof track brake system. Background technique [0002] Gantry cranes are large-scale loading and unloading equipment for open-air operations in railway freight yards. Due to the large windward area and high center of gravity, under the influence of strong winds, there is a safety risk of being blown out of control by strong winds and even overturning. The wind-proof braking function (braking force) of the existing rail gantry crane in working condition is determined by the sliding friction force between the driving wheel of the crane and the rail, which is proportional to the quality of the crane. The ordinary gantry crane (36T, span 26m, self-weight 130 tons) as an example, the dynamic wind-proof braking force of the machine is: 130T*50%*0.1 (the sliding friction coefficient between the...
