Abstract
The utility model discloses an installing device of a static test displacement sensor. The installing device comprises a base, a limiting rod and two chucks, wherein the limiting rod is installed on the base, and the two chucks symmetrically installed on the limiting rod are fixed through tightening bolts. The base is arranged into a step shape, a limiting rod installing hole is formed in the topmost face of the step, the tightening bolts are arranged on one side face of the limiting rod installing hole, and the lower plane parallel to the top face is arranged into a mirror face contact face. It can be guaranteed that the displacement sensor is installed in the displacement measuring direction and initial values of multiple displacement meters are approximate, the installing speed of the displacement sensor can be greatly increased, the pin stuck phenomenon of the displacement sensor is effectively avoided, displacement measurement accuracy in the foundation pile and foundation quality detection process is guaranteed, the sensor is installed through the two chucks and the limiting rod, the influence of visual angle errors caused by manual installation is avoided, and therefore displacement sensors of the same model can be installed with the same accuracy by different persons.
Description
Technical field
The utility model relates to a kind of static loading test displacement transducer erecting device, is mainly used in the installation of foundation pile and foundation displacement measurement displacement meter.
Background technology
During foundation pile and ground detect, very important parameter is the displacement measurement of foundation pile and ground under certain load action, test is mainly to determine according to load-displacement (Q～S) curve whether the supporting capacity of foundation pile and ground meets designing requirement, and therefore load and displacement measurement data are accurately the most key problems.Load adopts column sensor and oil pressure sensor to complete mostly at present, easy for installation and test accuracy is higher, less on test accuracy impact, the displacement measurement at present MS-50 type displacement transducers that adopt completes more, mounting means adopts artificial direct hand-held displacement transducer and Universal fixed support connection, there is following problem in this kind of mounting means: 1. the verticality of range estimation control bit displacement sensor, the general verticality that is difficult to guarantee displacement transducer.2. for preventing from loading Influence from Eccentric, current specifications regulation will be installed 2-4 displacement transducer, is difficult to guarantee the displacement transducer initial value of measurement same parameters close (according to error theory: same model sensor initial value is close can guarantee that the certainty of measurement of several sensors is also identical) with the installation of artificial hand-held displacement transducer.If if 3. artificial hand-held displacement transducer is installed firmly excessive too quicklyly, may cause that pointer is stuck can not free-extension, or pointer tilts and can not cannot measure displacement by free-extension with the excessive pointer that also causes of contact surface frictional force.In the problems referred to above, 1, the appearance of 2 two kinds of situations impacts to the precision of test, after loading, the 3rd kind of situation ordinary test find that instrument appearance extremely can be by readjusting after displacement transducer, again test, the precision of test is reduced greatly, because accumulated error has increased, also greatly reduce the efficiency of test simultaneously.
Utility model content
The utility model object is to overcome the above-mentioned shortcoming that prior art exists, and a kind of static loading test displacement transducer erecting device is provided.
For achieving the above object, the technological means that the utility model adopts is: a kind of static loading test displacement transducer erecting device, comprise base, be arranged on gag lever post on base, by screwing symmetrical two chucks installing on the fixing gag lever post of bolt, described base is set to step, on the top face of step, have gag lever post installing hole, on gag lever post installing hole one side, be provided with and screw bolt, be set to minute surface contact surface at the lower plane parallel with top surface.
Further, the U-shaped fork that described chuck is connected by chuck pedestal, with chuck pedestal, wherein on chuck pedestal, have through hole for being socketed in gag lever post, there is the bolt hole that screws communicating with chuck base block hole at chuck pedestal side opening, screw bolt and be arranged on and screw in bolt hole, on two fork arms of U-shaped fork, have draw-in groove.
The beneficial effects of the utility model are: can guarantee that displacement transducer installs according to displacement measurement direction, and can guarantee that multiple displacement meter initial values are close, can greatly improve the speed of installation position displacement sensor simultaneously, effectively prevent the generation of displacement transducer card pin phenomenon, thereby guarantee the precision of displacement measurement in foundation pile and foundation quality detection, adopt two chucks and gag lever post sensor installation, solve artificial installation visual angle error effect, made different people that same model displacement transducer installation accuracy is installed consistent.

In figure: 1, base, 2, gag lever post, 3, chuck, 4, screw bolt, 5, draw-in groove, 6, minute surface contact surface, 7, object, 8, displacement transducer, 9, probe.
The specific embodiment
A kind of static loading test displacement transducer erecting device as shown in Figure 1, 2, comprise base 1, be arranged on gag lever post 2 on base, by screwing symmetrical two chucks 3 installing on the fixing gag lever post of bolt 4, described base 1 is set to step, on the top face of step, have gag lever post installing hole, on gag lever post installing hole one side, be provided with and screw bolt 4, be set to minute surface contact surface 6 at the lower plane parallel with top surface.
Further, the U-shaped fork that described chuck 3 is connected by chuck pedestal, with chuck pedestal, wherein on chuck pedestal, have through hole for being socketed in gag lever post 2, there is the bolt hole that screws communicating with chuck base block hole at chuck pedestal side opening, screw bolt 4 and be arranged on and screw in bolt hole, on two fork arms of U-shaped fork, have draw-in groove 5.
When use, pack gag lever post 2 into base 1, tighten and screw bolt 4, respectively upper and lower adjustable two chucks are arranged on gag lever post in opposite directions, first set and fix by screwing bolt 4 according to the initial value of test direction of displacement and sensor, displacement transducer 8 is put into two chucks that arrange in opposite directions, and be placed in draw-in groove 5, guarantee that sensor probe 9 is reliably connected with the minute surface contact surface 6 on base 1, fix chuck 3, then the static loading test displacement transducer erecting device fixing is moved on measured object 7, after displacement transducer is fixing with the universal fixator that is connected measuring basis, that unclamps chuck place, top screws bolt 4, remove the top chuck 3 of fixed displacement sensor 8, then unclamp the bolt that screws at chuck place, bottom, moving down bottom chuck makes the draw-in groove 5 of bottom chuck depart from displacement transducer 8, unclamp the bolt that screws being positioned on base, hand-held bottom chuck, upwards remove gag lever post 2, after gag lever post 2 departs from base 1, side direction is removed bottom chuck, base 1 is stayed on measured target thing 7 and is worked together with displacement transducer 8, same method is installed other displacement transducers.
The present embodiment is only with the explanation of this apparatus function of opposing, and or not as the restriction to this device, the simple replacement that those skilled in the art carry out according to this apparatus structure, is not included within the scope of the rights protection of this patent.
