Abstract
The utility model discloses a sensor. The sensor comprises a sensor basal body, wherein a sensor is arranged in the sensor basal body, the sensor comprises a tubular closed body, mercury beads arranged in the closed body, and at least a pair of contact point conducting wires arranged at intervals in the closed body, and each pair of contact point conducting wires respectively stretch out of the closed body. The sensor has the advantages of low cost, high measuring accuracy, convenient installation and portability.
Description
Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of rail sensor.
Background technology
At present, all use track scale to measure to the load-carrying vehicle of exercising in orbit, and most of rail sensor that adopts comes check weighing, can make track scale realize no foundation ditch like this, no stalk platform is saved cost of equipment and installation and maintenance expense greatly.Existing rail sensor has three kinds: a kind of is direct adhering resistance strainometer on rail, form the Hui Sitong bridge circuit, but this mode exists paster, compensation, the sealing technology complexity of sensor, the technical matters that is not easy to realize.Another kind is to punch on rail, fills in LOAD CELLS in the hole, and this mode sensor measurement precision is low, and processing mounting holes is relatively more difficult again at the scene, also is difficult for realizing.Relatively science is that the third is the orbit-shaped sensor, this rail mounted LOAD CELLS is the elastic strain body and directly replaces track, but the deficiency that exists mainly shows the easy title phenomenon of losing, and installs, carries inconvenience simultaneously, installation site accuracy requirement height, use cost is higher.
Summary of the invention
The purpose of this utility model provides that a kind of cost is low, measuring accuracy is high and be convenient to install the rail sensor that carries installation.
The technical scheme that realizes the utility model purpose is as follows:
Rail sensor comprises sensor base, is provided with sensor in the sensor base, this sensor comprises the obturator of tubulose, and the globule that is provided with in the obturator, and in obturator, being arranged at intervals with at least one pair of contact lead, described every pair of contact lead extends outside the obturator respectively.
The upper surface of described sensor base is provided with slot, is fixed with connector block by patching in slot, and the connector block lower surface is provided with and patches the corresponding plugging tongue that groove is connected.
Adopted such scheme, the utility model advantage just is to be arranged on the many to the contact lead of interior globule of described obturator and interval setting, utilize the level meter principle, the contact lead conducting that when obturator is in desired location, will be provided with at interval by globule, so the positional accuracy measurement height, while volume easy for installation is urinated in carrying.
The upper surface of described sensor base is provided with slot, is fixed with connector block by patching in slot, and the connector block lower surface is provided with and patches the corresponding plugging tongue that groove is connected.By on sensor base, assembling connector block, can increase sensor and wear no resistance, improve the serviceable life of rail mounted sensor.Simultaneously wear surface is replaceable, the maintenance of track scale is more prone to and make things convenient for, makes sensor increase in serviceable life.
