Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail the specific embodiment of the present invention, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contribute to its enforcement.
As depicted in figs. 1 and 2, the invention provides a kind of caliberating device of stay wire displacement sensor, comprise base plate 1 and gauge block 2.Base plate 1 has the sensor settings position for placing stay wire displacement sensor, gauge block 2 is arranged on base plate 1, and gauge block 2 is also positioned at the side of sensor settings position.
Specifically, as depicted in figs. 1 and 2, gauge block 2 is provided with multiple, and all gauge blocks 2 and sensor settings position are on same straight line.Base plate 1 is strip plate, and the end face of base plate 1 is plane, and gauge block 2 is for being equally spaced on the end face of base plate 1, and the distance between adjacent two gauge blocks 2 is greater than the distance between stay wire displacement sensor and nearest gauge block 2 being in sensor settings position.
As shown in Figure 2, gauge block 2 is T-type structure, and it comprises the connecting portion 21 that is fixedly connected with base plate 1 and to be arranged on connecting portion 21 and for the support sector 22 of the bracing wire of fixing stay wire displacement sensor.Support sector 22 is the rectangular block shape structure vertically arranged, the length direction of support sector 22 and the length direction of base plate 1 perpendicular.
As preferably, as shown in Figure 2, the top of support sector 22 has the storage tank 23 of bracing wire for holding to pull out from stay wire displacement sensor, bracing wire on the groove bottom of storage tank 23 and stay wire displacement sensor exports and is in same level height, namely the groove bottom of storage tank 23 is equal with the vertical range that the bracing wire on stay wire displacement sensor exports between distance base plate 1 end face, the bracing wire level of stay wire displacement sensor so just can be made to pull out, guarantee the accuracy measured.
Storage tank 23 on gauge block 2 is positioned at the vertical centerline position of support sector 22, storage tank 23 is that downwardly support sector 22 is inner extended from support sector 22 end face center, and along the thickness direction Guan Chu support sector 22 of support sector 22, the opening size of storage tank 23 should be greater than the bracing wire diameter of stay wire displacement sensor, be less than the diameter of the bayonet unit that stay wire displacement sensor end of pulling carries, so that bracing wire is fixed on storage tank 23 place of gauge block 2.
As depicted in figs. 1 and 2, in the present embodiment, there are two threaded holes the sensor settings position on the base plate 1 of caliberating device, is used for installing stay wire displacement sensor.Have two threaded holes and dowel hole at interval of 10cm, be used for installing the gauge block 2 of fixation measuring, and each gauge block 2 as shown in Figure 2, connecting portion 21 is provided with two dowel holes and two installation screws, is convenient to be fixed on accurately on the base plate 1 of caliberating device.
