one end of the bridge plate 3 is hinged with the fixed frame 2, and the other end of the bridge plate 3 is freely arranged; two ends of the first hydraulic cylinder 5 are respectively hinged with the middle part of the fixed frame 2 and the middle part of the bottom surface of the bridge plate 3;
one end of the lip plate 4 is hinged with the free end of the bridge plate 3, and the other end of the lip plate 4 is freely arranged; two ends of the second hydraulic cylinder 6 are hinged with the bottom surface of the bridge plate 3 and the bottom surface of the lip plate 4 respectively.
Wherein, 1, bridge plate 3 include the mounting bracket and weld the decorative pattern steel sheet on the mounting bracket, set up like this and can increase the frictional force between tire and the bridge plate 3 to realize antiskid, and can improve the bearing capacity of bridge plate 3, effectively guarantee the ability of bridge plate 3 bearing load. 2. The platform 1 is provided with an embedded pipe for wiring.
Working principle: the platform 1 is fixedly arranged on the ground or other stations (such as a warehouse opening), and the height of the platform can be flush with the ground or higher than the ground according to the carrying arrangement. In use, one end of the bridge plate 3 is driven to rise by the first hydraulic cylinder 5, and the bridge plate is stopped when the free end of the bridge plate 3 rises to be consistent with the height of the carriage. At this time, the second hydraulic cylinder 6 drives the lip plate 4 to rotate around the hinge point of the lip plate, so that the lip plate 4 is adjusted to be horizontal, and the lip plate 4 is put on the carriage to prolong the boarding area.
The utility model realizes the variable amplitude of different heights of the climbing bridge through full hydraulic driving control; the boarding area of the dock leveler is prolonged, the rotation amplitude of the bridge plate 3 and the lip plate 4 is guaranteed, the moving safety of the transport vehicle is improved, the bridge plate 3 is convenient to stretch and retract, and the utilization rate of space is improved.
