Description
Technical Field
The invention relates to a stress measuring device and method for a leveling gas chamber piston balance system.
Background
The gas holder is widely applied to the fields of metallurgy, nonferrous metal, petrochemical industry and the like and is used for storing various energy media. The gas chamber piston balancing system is an important device arranged on a rubber film sealed gas chamber or a similar gas chamber, and mainly has the main function of maintaining the balance of the piston running up and down in the gas chamber and avoiding inclination, drift or torsion.
The principle of the piston balancing system is as follows: a plurality of hoisting points are arranged on the top of a piston in pairs, for each pair of hoisting points, two ends of a steel wire rope are tied to the hoisting points of the steel wire rope respectively, the middle part of the steel wire rope is led out of a side plate through the piston and a pulley block on the top of the cabinet, and a leveling balancing weight is tied to the steel wire rope outside the side plate; when two lifting points on the piston are changed, one is loose and the other is tensed, and at the moment, the leveling balancing weight block connected through the movable pulley can automatically tension the loose steel wire rope, so that the piston is always kept in a horizontal state, and the piston is prevented from inclining and drifting;
in the process of up-and-down operation of a piston in a gas chamber, the piston used for the functions can be influenced by factors such as air flow, friction force of a positioning wheel and a guide wheel on a steel wire rope and the like to cause uneven stress on two paired steel wire ropes at a hanging point, so that the balance of the piston of the gas chamber is influenced, and serious safety accidents can be caused in serious cases.
In order to solve the above problems, some enterprises have to install a measuring device for inclination and drift on the piston, and periodically enter the cabinet (enter the piston) for a passive means such as inspection, which has a certain hysteresis.
In order to overcome the problem of hysteresis, the chinese patent CN 202252811U sets a steel wire rope tension sensor and a transmitter device on a steel wire rope running with a piston between a top pulley block and a leveling counterweight block outside a gas chamber cabinet, and this structure can solve the problem of information hysteresis, but has the following disadvantages: 1. the weight block (called as weight in original patent) and the wire rope are lowered along with the rise of the piston in the cabinet and raised along with the fall of the piston in the cabinet, so the weight block and the wire rope are always in the up-and-down motion state. The position of the transmitter and the position of the tension sensor are always in a movable state when the gas cabinet works, and a multilayer cabinet body corridor is arranged outside the gas cabinet, so that the measuring device cannot meet the working requirement; 2. for a first reason: the signal of the original patent transmitter needs to be transmitted through a cable, and the cable transmission cannot be realized under the motion states of a leveling balancing weight (called a heavy hammer in the original patent) and a steel wire rope; 3. the most important is that a multilayer corridor is arranged on the outer side of a side plate where the steel wire rope and the heavy hammer are located, a small hole for passing through the heavy hammer is reserved at the corridor, and dynamic transmitters and cables cannot freely pass through the multilayer corridor due to structural and technological requirements.
