Abstract
The utility model discloses an intelligence stretch -draw is measured sensor of elongation and is checked device, including jack and sensor, the sensor surface is equipped with the sensor loop bar, the sensor loop bar is equipped with the scale, 0 value of scale pushes away the piston for the complete oil return of jack just pushes up and is 0 position at the bottom elongation, the sensor is provided with the measurement pointer with the position that the jack plane corresponds. The utility model discloses can guarantee normal stretch -draw under the sensor condition malfunctioning because of a variety of causes, the measurement of stretch -draw elongation is accurate, reduces elongation measuring safety risk.
Description
Technical field
The utility model relates to the field that intelligent tensioning measures elongation, specifically, relates to the sensor capacity checking device that a kind of intelligent tensioning measures elongation.
Background technology
At present, the prestress wire stretch-draw of bridge precast beam plate construction adopts intelligent tensioning substantially, the elongation of intelligent tensioning is communicated on computer after being detected by sensor that lifting jack is installed and related accessory in stretching process by lifting jack, but lifting jack is repeatedly moving or is easily causing faulty sensor or misalignment after using, the elongation value of stretching that computer demonstrates is abnormal, have impact on the program of stretch-draw to a certain extent, and common undertaken measuring by Steel Ruler not only easily there is reading error, also there is potential safety hazard to a certain extent.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, the sensor capacity checking device that a kind of intelligent tensioning measures elongation is proposed, can in stretching process accurately safety carry out reading, also can check the reading of intelligent tensioning, to the implementation dual control of elongation, improve the quality of girder plate prestress stretch-draw.
Intelligent tensioning of the present utility model measures the sensor capacity checking device of elongation, comprise lifting jack and sensor, described sensor surface is provided with sensor loop bar, described sensor loop bar is provided with scale, 0 value of described scale is the complete oil return of lifting jack and pushing tow piston is in the position that bottom extended amount is 0, and the position that described sensor is corresponding with lifting jack plane is provided with measurement pointer.
The precision of described scale is 1mm, and the range of described scale is the length of 0 value when stretching out completely to lifting jack, and described measurement color of pointer is red.
The beneficial effects of the utility model: (1) can when sensor because of a variety of causes malfunctioning ensure normal stretch-draw; (2) measurement of stretching extension value is accurate, reduces the security risk that elongation is measured; (3) accuracy of reading safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: sensor loop bar 1, scale 2, measurement pointer 3.
Embodiment
The sensor capacity checking device that the intelligent tensioning now proposed the utility model in conjunction with the accompanying drawings and embodiments measures elongation is described in further detail.
Intelligent tensioning of the present utility model measures the sensor capacity checking device of elongation, comprise lifting jack and sensor, described sensor surface is provided with sensor loop bar 1, described sensor loop bar 1 is provided with scale 2,0 value of described scale 2 is the complete oil return of lifting jack and pushing tow piston is in the position that bottom extended amount is 0, the position that described sensor is corresponding with lifting jack plane is provided with measures pointer 3, the precision of described scale 2 is 1mm, the range of described scale 2 is the length of 0 value when stretching out completely to lifting jack, and described measurement pointer 3 color is red.
When intelligent tensioning measures the sensor capacity checking device use of elongation, be arranged on the sensor loop bar 1 of intelligent tensioning lifting jack, by carrying out reading to elongation after stretch-draw, read elongation by scale to check sensor reading, also can deal with the normal stretch-draw of sensor when malfunctioning simultaneously, ensure stretch-draw safety.
