Problems solved by technology
There are following disadvantages in this way of locking spindles. Firstly, once the hydraulic machine breaks down, the arc door of the surface hole may lose its binding force and slide down, which poses a great safety hazard. The service life of the hydraulic press
Therefore, the existing methods and devices for locking spindles with surface hole arc doors are still not perfect enough.

Embodiment Construction
[0030] look first figure 1 and figure 2 , figure 1 and figure 2 demonstrates the principles of the invention, where figure 1 It is a schematic diagram when the surface hole arc door of the present invention is not locked. At this time, the surface hole arc door is in a closed state, the double-cylinder suspension hydraulic press 3 is in a pressureless state, and the pull rod 7 is in a vertical position; figure 2 It shows the schematic diagram of the surface hole arc door of the present invention when the spindle is locked. At this time, the surface hole arc door is pulled by the gate hoist to rotate upwards, and at the same time, the pull rod 7 is driven by the double-cylinder suspension hydraulic press 3 to rotate and swing upwards to avoid The running track of the surface hole arc door is above the hook hole at the lower end of the hook-shaped flange plate 8 when the suspension shaft device 6 of the surface hole arc door moves to the original position of the pull ro...

The invention discloses a hydraulic rotating type locking method and device for a surface outlet radial gate. According to the principle, a pull rod and a dual-cylinder suspension type hydraulic machine are arranged on gate pier side walls on the two sides of the surface outlet radial gate through stepped suspension shafts, the pull rod can be driven by the dual-cylinder suspension type hydraulic machine to rotate and swing around the stepped suspension shaft, meanwhile, a suspension shaft device is arranged at the lower end of the surface outlet radial gate, when the surface outlet radial gate moves upwards to a specified position, the suspension shaft device at the lower end of the surface outlet radial gate is embedded into a suspension hook hole of a hook-shaped flange plate at the lower end of the pull rod, and therefore the surface outlet radial gate is locked. Compared with the prior art, the method and device have the advantages that the structure is simple, safety and reliability are achieved, and mounting and dismounting are convenient, after the surface outlet radial gate is locked, an operation gate and the hydraulic machine of the locking device can both carry out pressure relief, and the advantages of avoiding the situation that accidents occur due to the fact the surface outlet radial gate slides down when the hydraulic machine breaks down and prolonging the service life of the hydraulic machine are achieved.
Description
technical field [0001] The invention relates to a method and a device for locking a spindle, in particular to a method and a device for hydraulically rotating spindle locking used for arc doors of surface holes. Background technique [0002] The arc gate is a common structure in hydraulic gates. It is a gate with a partially arc-shaped surface of a cylinder. The center of the supporting hinge of its support arm is located at the center of the circle. When opening and closing, the arc gate rotates around the center of the supporting hinge. Arc gates are usually composed of three parts: rotating gate body, embedded components and opening and closing equipment. The curved gate has no door slot, small opening and closing force, and good hydraulic conditions. It is widely used in various types of waterways as a working gate. According to the depth of the water level above the top of the gate, the arc gate is divided into open-top type and submerged-hole type. Among them, the wat...
