[0014] The utility model provides a multifunctional size measuring device for road and bridge construction, having the following beneficial effects:

[0015] (1) The multi-functional dimension measuring device for road and bridge construction, through the cooperation of internal components of the detection assembly, the connecting rope is perpendicular to the center position of the mounting block under the restraint of the restraint block. The detection wheel presses against the side of the connecting rope, causing the movable block to slide inside the movable groove. The distance sensor detects the distance of the movable block and feeds it back to the controller. The controller sends the deviation situation of the connecting rope to the operator. The operator adjusts the length of the adjusting rod accordingly based on the feedback information to make the mounting plate horizontal. The spirit level is used for auxiliary observation. After the mounting plate is horizontally adjusted in this way, the level is installed for detection. The switch on the side of the counterweight controls the motor to drive the winding shaft to release the connecting rope. The counterweight weights the connecting rope vertically to perform perpendicularity detection. In this way, the measuring device can perform various detections and can assist in the horizontal adjustment of the spirit level bracket;

[0016] When the connecting rope is unwound synchronously, the connecting rope causes the detection wheel to rotate by friction. The side of the detection wheel presses against the detection rod, causing it to slide inside the slotted groove and trigger the pressure sensor to feed back to the controller. When passing through the detection groove position, the detection rod moves away from the pressure sensor under the deformation force of the return spring. This process repeats, and each time it is triggered, the calculated distance is one centimeter. In this way, the distance that the connecting rope is pulled out can be obtained. In this way, the distance of the object after construction can be detected through the connecting rope. In this way, the measuring device can perform dimension detection, reducing the tools to be carried and improving functionality and convenience.

[0017] (2) The multi-functional dimension measuring device for road and bridge construction, through the cooperation of internal components of the auxiliary assembly, the bolts on the side of the connecting rod are loosened and rotated and slid inside the restraint rod to the appropriate angle and then tightened. The restraint shaft fits the connecting rope on its side. The slider slides inside the sliding groove, causing the restraint rod to move its position. In this way, the connecting rope is in a folded angle state, facilitating the detection of the extended position of the connecting rope. In this way, it is convenient for the measuring device to perform detection operations and improve adaptability. Description of the Drawings

[0031] The working principle of this utility model:

[0032] During use, the connecting rope 24 is vertically located at the center position of the mounting block 26 under the restraint of the restraint block 27. The detection wheel 28 presses against the side of the connecting rope 24, causing the movable block 262 to slide inside the movable slot 261.

When the connecting rope 24 is unreeled synchronously, the connecting rope 24 causes the detection wheel 28 to rotate by friction. The side of the detection wheel 28 presses the detection rod 292 to slide inside the slot 29 and squeeze to trigger the pressure sensor 291, which feeds back to the controller 13. When passing through the position of the detection slot 281, the detection rod 292 moves away from the pressure sensor 291 under the deformation force of the return spring 293. This process repeats, and each time it is triggered, the calculated distance is one centimeter, so that the pulled-out distance of the connecting rope 24 can be obtained. In this way, the distance of the object after construction can be detected through the connecting rope 24.
