The invention relates to the technical field of gate locking beams, in particular to a locking beam labor-saving throwing and withdrawing device and a gate locking system. The locking beam labor-saving throwing and withdrawing device comprises a door-shaped frame stretching across the two sides of a locking beam, a handle rotationally arranged above the door-shaped frame, a threaded rod arranged in the handle in a penetrating mode and two pulley blocks used for being clamped on the two sides of a web of the locking beam and abutting against the lower portion of an upper wing plate of the locking beam; the threaded rod is connected with the pulley blocks; and the handle is in threaded fit with the threaded rod so as to drive the threaded rod and the pulley blocks to move up and down through rotation of the handle. According to the arrangement, the locking beam is lifted from the ground to a sliding rail by utilizing the labor-saving principle of spiral lifting and pulley rolling, so that easy throwing and withdrawing are realized; and the device is low in structural cost, high in reliability, low in later maintenance cost, simple in structure, convenient to operate, labor-saving and money-saving.
Description
technical field [0001] The present application relates to the technical field of locking beams, and more specifically, to a locking beam labor-saving switching device and a gate locking system. Background technique [0002] The locking beam is used to lock the gate, that is, to fix the gate at a specified opening position, so as to relieve the load of the hoist or remove the hoist. At present, the weight of the locking beam in water conservancy projects is 257kg. Some of the traditional automatic switching devices for locking beams are hydraulic systems or electrical systems, which are complex in structure, high in maintenance costs, and prone to failure. [0003] The traditional manual throwing and retreating of the locking beam is to move the locking beam manually. During the opening and closing process of the gate, in order not to hinder its lifting and falling, it needs to be manually lifted to complete the movement of the locking beam so that it leaves and enters the ga...
