Automatic catwalk bridge retracting and releasing device

The invention relates to an automatic catwalk bridge retracting and releasing device. The automatic catwalk bridge retracting and releasing device comprises a catwalk bridge and a set of steel wire rope winches; the catwalk bridge is hinged to a catwalk machine platform so that the catwalk bridge can rotate around a hinge point; the steel wire rope winches are connected with the catwalk bridge through a set of pulley seats, pulleys and steel wire ropes; and the steel wire rope winches provide power for ascending of the catwalk bridge, and pitching motion of the catwalk bridge is achieved. According to the automatic catwalk bridge retracting and releasing device, the winches are adopted for ascending, remote automatic operation can be achieved, an original manual operation mode is replaced, time and labor are saved, safety and reliability are achieved, and the deck space does not need to be occupied. 本发明涉及一种自动收放猫道桥装置，包括一台猫道桥，一组钢丝绳绞车，所述猫道桥与猫道机平台铰接，使猫道桥能够绕铰点旋转；所述钢丝绳绞车通过一组滑轮座及滑轮、钢丝绳连接猫道桥，由钢丝绳绞车为猫道桥起升提供动力，实现猫道桥俯仰运
