Technical Field

[0001] The utility model belongs to the technical field of displacement measurement, in particular to a displacement measurement mechanism. Background Art

[0002] The expansion measuring device is a mechanism that is fixed to the base of the gas turbine to measure the expansion of the gas turbine under various operating conditions. The measuring shaft is fixed by a top block to ensure the accuracy of the measuring shaft value. It has the advantages of reliable operation, good performance and compact structure.

[0003] The patent with publication number CN219161219U discloses a displacement measurement mechanism. By setting a guide plate, a guide block and a fixed scale, the mounting shaft is pushed when the engine expands. The mounting shaft drives two guide blocks to move synchronously through two mounting blocks, and the two guide blocks slide between the fixed scale and the guide plate, which is used to improve the stability of the movement of the movable scale block and improve the accuracy of measuring the expansion of the engine under vibration.

[0004] However, when the above device is in use, since the end of the mounting shaft is bonded and fixed to the measuring part of the gas engine, large vibrations will occur during the operation of the gas engine, and the fixed scale will also deviate with the vibration, which is not conducive to reading. When the gas engine stops working, the expansion will shrink, causing the mounting shaft to move with it, and the measurement result is also prone to deviations, resulting in errors in the measurement of the device and low accuracy.

[0007] Furthermore, the measuring component includes a pressure sensor, push plate 1 and push plate 2. The pressure sensor is arranged on the side wall of the shell and away from the push rod. The push plate 1 and push plate 2 are both slidably arranged in the shell. The push plate 1 is connected to the push rod, and a spring 1 is arranged between the push plate 1 and the push plate 2.

[0008] Furthermore, a digital display is provided on the top wall of the shell, and the digital display is connected to the pressure sensor via an electrical signal.

[0009] Furthermore, the first spring is a linear spring.

[0010] Preferably, the buffer guide mechanism includes a buffer groove and a damping rod, the buffer groove is arranged in the base, a guide rod is movably penetrated on the top wall of the buffer groove, a plurality of guide rods are symmetrically arranged, a limit block is arranged at the bottom end of the guide rod, the shell is arranged at the top end of the plurality of groups of guide rods, a spring 2 is sleeved on the guide rod, the spring 2 is arranged between the shell and the base, the damping rod is arranged in the buffer groove, and the end of the damping rod movably penetrates the top wall of the buffer groove and is connected to the bottom wall of the shell.

[0011] The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides a displacement measuring mechanism, which can convert the displacement distance of the push rod into pressure by setting push plate one and push plate two, and cooperate with a spring, and squeeze the pressure sensor, and cooperate with a digital display to facilitate recording and displaying the force data of the pressure sensor, thereby facilitating recording and observing the movement value of the push rod, effectively avoiding the impact of vibration on the equipment during the operation of the gas engine, and also effectively avoiding the numerical deviation of the retraction after the gas engine stops working; by setting a damping rod, a guide rod and a spring, a certain buffer can be provided for the shell to reduce the impact of vibration on the equipment.
