Background
At present, as is known, the displacement meter generally has a range of 1000-2000 due to the limitation of volume and other conditions, because a general displacement meter potentiometer and a winding wheel retracting a steel wire rope share one shaft, the number of winding turns of the steel wire rope is equal to the number of rotation turns of the potentiometer, so that an analog voltage signal is output to obtain a measurement result, but because the diameter of the winding wheel is smaller, the diameter of a coil is increased when the number of winding turns is larger, but the voltage value output by the potentiometer rotating one turn is stable and unchanged, so that a great error is generated on the measurement result, and a production merchant generally controls the range of the displacement meter to be 1000-2000 mm. However, in general, a measured object is likely to exceed a measuring range, namely, a measuring limit is reached, if the measured object is extended further, the displacement meter is likely to be damaged, and equipment is damaged, particularly for monitoring displacement of a landslide, due to uncertainty of crack expansion at the rear edge of the landslide, the length is likely to exceed the measuring range in the crack development process, so that the monitoring equipment cannot effectively perform early warning, and meanwhile, another result caused by the out-of-range is that a sensor is damaged, and long-term monitoring data fails.

The invention relates to a travel increasing device of a pull rope displacement meter, which comprises a winding shaft, a protective cylinder and a cylindrical pull rod, spool one end is provided with the connecting hole, and the spool other end is provided with the shrinkage pool, cylinder pull rod one end is the cylinder and is provided with annular groove, and the cylinder pull rod other end is provided with the fixed orifices, and the winding has preparation wire rope on the spool, prepares wire rope one end and spool connection, prepares the wire rope other end and is connected with the fixed orifices, and inside cylinder pull rod annular groove one end inserted the spool shrinkage pool, spool lateral wall shrinkage pool one end be provided with three thread grooves of group with the shrinkage pool intercommunication, the inside equal threaded connection of three thread groove of group has stop screw, every group the inside wall that the thread groove is close to cylinder pull rod annular groove one side all is provided with annular standing groove, every group the inside spring that all is provided with of annular standing groove, every group stop screw is close to cylinder pull rod annular groove one side.
According to the stay cord displacement meter range extending device, an external thread is arranged on one side, close to a connecting hole, of a winding shaft, an internal thread matched with the external thread of the winding shaft is arranged at a corresponding position on the inner wall of a protection cylinder, and the length of the protection cylinder is smaller than that of the winding shaft.
Compared with the prior art, the invention has the beneficial effects that: when the specific length of an uncertain measuring object is measured, the range extending device can be used, if the initial range of the displacement meter is not exceeded, the normal measuring result of equipment cannot be influenced by installing the range extending device, but once the initial range is exceeded, the device can play a role, a prepared steel wire rope is released, and the range is increased.
