Description

A prevent running stopper for harbour door machine

Technical Field

The utility model relates to a harbour machinery equipment technical field, concretely relates to a prevent running stopper for harbour door machine.

Background

At present, the frequently adopted braking measures of the port door machine in wind prevention are as follows: 1. the manual rail clamping device is greatly influenced by rail subsidence and distortion, when the rail deforms, the length of a rail clamp of the manual rail clamping device is fixed, and the manual rail clamp cannot clamp the rail at the position properly; if the rail condition is good, the rail clamping pliers can clamp the rail well every time. At the moment, the rail clamping device has certain windproof capacity, but the friction force between the rail clamping pincers and the rail generated by mechanical force is limited, and when the wind force blowing to the gantry crane is large to a certain degree, the static friction force between the rail clamping pincers and the rail is overcome, so that the gantry crane starts to move. 2. The steel wedge blocks are braked, the steel wedge blocks need to be frequently plugged into and pulled out of the travelling wheels, and the steel wedge blocks cannot play a role when the gantry crane is frequently moved for operation; when wind power is high, the windproof measure that wedges are manually inserted between the travelling wheels and the track has poor effect; in addition, the wedge block is inserted between the travelling wheel and the track by hands, which is not safe. 3. The anchoring device can only play a role when the gantry crane is not in operation and stops at the position of the reserved anchoring pit, the wind-proof capability is also strong, and the measure cannot be adopted at ordinary times because the position where the gantry crane frequently moves is not exactly at the position of the anchoring pit, and the gantry crane cannot be blown by sudden typhoon. 4. The friction sheet wheel clamping device can only prevent the travelling wheels from rolling on the track but cannot prevent the travelling wheels from sliding on the track, and when the wind power blowing to the gantry crane is large to a certain degree, the travelling wheels can start to slide on the track to drive the whole gantry crane to move; the friction plate wheel clamping device also enables the friction plate to clamp the travelling wheel through the reset spring force, after the friction plate wheel clamping device is used for a period of time, the reset spring frequently works and elastically descends, the force for clamping the travelling wheel through the friction plate also gradually descends, and the reset spring force is not easy to detect and judge at ordinary times; in addition, the wheel clamping device controls operation systems such as a pump station and a hydraulic pusher to work due to the fact that the spring force with large reaction force is overcome, faults are frequent, and the long-term normal use is influenced due to the fact that the oil way internal leakage condition generally exists.
