[0003] The lifting methods of the existing lifting bridges generally adopt hydraulic lifting or cable pulling, but the existing lifting bridges using steel cables generally do not have good protection measures. Once the steel cables break, the bridge span will fall. Threatening the safety of passing ships, causing serious safety accidents, and the existing lifting bridges generally do not have auxiliary lifting devices, once the cable type lifting device fails, the device will not be able to operate, and the traffic will be paralyzed

Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] Such as figure 1 As shown, a lifting bridge with good safety includes a pillar 1, a base 2, a rotating plate 3, a pole 4, a lifting mechanism and a supporting mechanism. There are two pillars 1, and the two pillars 1 are respectively arranged on the base 2 The two ends of the base 2 are provided with a notch in the middle of the base 2, the rotating rod is arranged at the notch, one end of the rotating plate 3 is hinged with the base 2, the pole 4 is arranged on the base 2, and the The lifting mechanism is arranged on the pole 4, and the supporting mechanism is arranged under the base 2;
[0026] When the device is installed, the two ends of the base ...

The invention relates to a high-safety lifting bridge which comprises a supporting column, a base, a rotating plate, a supporting rod, a lifting mechanism and a supporting mechanism, a notch is formedin the middle of the base, the rotating rod is arranged at the notch, the supporting rod is arranged on the base, the lifting mechanism is arranged on the supporting rod, and the supporting mechanismis arranged below the base. In the high-safety lifting bridge, rotation of the rotating plate is achieved through the lifting mechanism, and the rotating plate is supported through the supporting mechanism. Compared with an existing lifting bridge, through linkage of the lifting mechanism and the supporting mechanism, the push plate abuts against the rotating plate all the time, supporting of therotating plate is achieved, a pure mechanical mechanism is adopted for linkage, use of electronic elements is avoided, the stability and the service life of the device are improved; meanwhile, the supporting mechanism pushes the rotating plate to rotate, the situation that the lifting mechanism cannot operate when the first pull rope is suddenly broken is avoided, double guarantees are provided for operation of the device, and practicability is improved.
Description
technical field [0001] The invention relates to a lifting bridge with good safety. Background technique [0002] The lifting bridge is a bridge span in the middle of the bridge that can be raised and lowered. There is a tower and a suspended balance weight at both ends of the movable bridge span. When the ship wants to pass, the bridge span is raised to temporarily interrupt the bridge Traffic, after the ship passes, it will be lowered back to its original position, and land traffic will resume. [0003] The lifting methods of the existing lifting bridges generally adopt hydraulic lifting or cable pulling, but the existing lifting bridges using steel cables generally do not have good protection measures. Once the steel cables break, the bridge span will fall. Threatening the safety of passing ships, causing serious safety accidents, and the existing lifting bridge generally does not have auxiliary lifting devices, once the cable type lifting device fails, it will cause the ...
