Embodiment Construction
[0026] The present invention will be described below with reference to the accompanying drawings.
[0027] see figure 1 -3. The dynamic windproof safety device for rail-mounted cranes provided by the present invention is mainly composed of high-strength steel block 1, energy-dissipating mild steel 16, trigger device and return device. The safety device is installed at the bottom of the crane close to the ground. Aiming at the safe braking when a sudden gust of wind is encountered in the working state of the rail-mounted crane, when braking, the electromagnet is energized, the trigger device is activated, and the stop block that is stuck on the high-strength steel block 1 is sucked out, and the high-strength steel block 1 is compressed by the spring 4 Under the action of the wind, it falls rapidly and falls into the grooves on both sides of the running track 15 on the ground. The high-strength steel block 1 follows the crane and continues to slide under the action of the wind,...

The invention discloses a dynamic windproof energy-consumption buffer braking device and method for a rail-mounted crane. The braking device comprises a high-strength steel block (1), energy-consumption mild steel (16), a triggering device and a return device, wherein the triggering device is used for enabling the high-strength steel block (1) and the energy-consumption mild steel (16) to be contacted, and the return device is arranged at the top part of the high-strength steel block (1) and is used for enabling the high-strength steel block (1) and the energy-consumption mild steel (16) not to be contacted. The method provided by the invention comprises the following steps that (I) in the normal running process of the crane, the brake of the crane is started when emergency braking is needed; an electromagnet (10) is electrified; a check block (12) is pulled out by a spring (9); and the high-strength steel block (1) rapidly falls under the action of a compression spring (4); (II) the high-strength steel block (1) moves along a trough (17) after falling to touch the first piece of energy-consumption mild steel (16). The device and the method disclosed by the invention are simple, and the method is reliable and can be easily realized.
Description
technical field [0001] The invention relates to a dynamic windproof safety braking device for a rail-mounted crane, which is mainly used for rail-mounted cranes such as portal type, portal type, and shore bridge type. Background technique [0002] Rail-mounted cranes often have wind disaster accidents in the case of sudden gusts. These wind and anti-skid safety issues are divided into two categories according to the working conditions of the crane at the time of the accident, namely, the wind and anti-skid problems in the non-working state and the working state. In the non-working state, the crane is in a static state, the technical research on windproof and anti-skid is relatively mature, and there are many related products, such as rail jacks, rail clamps, iron shoes, anchoring devices and so on. And in the working state, the windproof and antiskid safety problem when the crane is running, there is no good solution and safety device at present. Some existing windproof br...
