Embodiment 1

[0038] A hydraulic lifting locking method, comprising the following steps:

[0039] a. Fix one end of the lifting rope 3 in the hydraulic lifting locking device on the hanging object, and pass through the hydraulic lifting device 2 to lock;

[0040] b. Loosen the lower lock of the hydraulic lifter 2, the oil cylinder of the hydraulic lifter 2 shrinks and runs, the hanging object falls by one cylinder stroke, the lower lock is clamped, the upper lock is released, the oil cylinder stretches out and runs one cylinder stroke, and the rope is lifted 3. Move one stroke length of the oil cylinder into the hydraulic lifter 2, and drop the hanging object by one stroke height;

[0041] c. When the hanging object reaches the locking position, the wedge-shaped locking seat 4 is pushed out by the jack 8 and contacts the locking support 6 on the surface of the hanging object, and the height of the hanging object is adjusted by relying on the inclined plane at the joint between the wedge-sha...

Abstract

The invention discloses a hydraulic lifting locking method, belonging to the field of lifting machinery. The hydraulic lifting locking method is characterized by comprising the following steps: a, fixing one end of a lifting rope on a lifting object and enabling the other end of the lifting rope to penetrate through a hydraulic lifter and be locked; b, loosening the lower locking in the hydrauliclifter, lowering the lifting object by one oil cylinder stroke, clamping the lower locking, loosening the upper locking in the hydraulic lifter, enabling an oil cylinder to extend to run for one cylinder stroke, and moving the lifting rope by one oil cylinder stroke length into the hydraulic lifter; c, when the lifting object reaches the locking position, pushing a wedge-shaped locking seat out bya jack and enabling the wedge-shaped locking seat to make contact with a locking support on the surface of the lifting object; d, displaying the force applying value by a digital display dynamometerin a lifting locking member, and adjusting the preloads of locking points to be the same for completing the locking of the lifting object. The hydraulic lifting locking method can realize the balanceof multi-point locking load, ensure that the hoisting object is uniformly stressed in the hoisting and transportation process, improve the locking reliability, greatly reduce the hoisting and operation risks, and has high operation safety.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a hydraulic lifting locking method. Background technique [0002] The hydraulic lifting device is a tool commonly used in lifting machinery for lifting heavy objects with large sizes and large loads. The lifting method of the hydraulic lifting device is usually to lift the heavy object in place at one time, and quickly connect accordingly. [0003] However, for the working conditions where it is necessary to keep the hoisting object in a lifted and loaded state for a long time or it needs to be lifted and installed in stages, the lifting method of the hydraulic lifting device has a greater safety risk. At this time, in order to ensure the safety of the operation, it is generally necessary to set up a separate locking device. In order to reduce the load of a single lock or to meet the needs of a balanced arrangement of locking points for large-scale heavy objects, ther...
