[0001] The utility model belongs to the technical field of pipe culvert trench excavation, and in particular relates to a pipe culvert trench excavation size measuring device. Background Art
[0002] During the excavation of the pipe culvert trench, the trench length and depth need to be measured. Construction workers usually set a sinker connected by a wire on the fixed plate, and then calculate the depth by measuring the length of the wire. That is, construction workers need to first measure the depth by wire and sinker, and then measure the width by other tools. The process of tool replacement is relatively cumbersome. At the same time, because the plate body wrapped with wire is in an unbalanced state, the measurement accuracy is lacking, especially in construction areas with special terrain and soil. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a culvert trench excavation dimension measuring device. Through the balancing block and the angle dial in the connecting plate, it can be more intuitive to observe whether the product is in a balanced state, and through the measuring mechanism that can be moved laterally, the product can be used in scenes with different widths and narrownesses, which improves the measurement accuracy and also makes the product have strong adaptability.
[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0005] A device for measuring the size of a pipe culvert trench excavation, comprising: a connecting plate, two supporting claws are transversely arranged on the bottom side of the connecting plate, a scale is fixedly arranged between the supporting claws, a slotted convex block is fixedly arranged on the front side of the scale, and two measuring mechanisms are slidably arranged inside the slotted convex block;
[0006] The measuring mechanism comprises a sliding plate, a fixed ring is fixedly arranged in the middle of the front side of the sliding plate, a pointer is fixedly arranged on the top side of the fixed ring, and a supporting frame is fixedly arranged on the bottom side.
[0007] Furthermore, a threaded rod is fixedly provided on the front side of the sliding plate, a nut is fixedly provided on the rod body of the threaded rod, and a limited ellipse is rotatably provided.
[0008] Furthermore, a wire rack is rotatably arranged inside the support frame, and a sinker block is fixedly arranged at the output end of the wire rack.
[0009] Furthermore, the connecting plate comprises a connecting shell, a rotating groove is provided on the front side of the connecting shell, and a rotating shaft is rotatably provided in the middle of the inner wall of the rotating groove.
[0010] Furthermore, a balancing block is fixedly arranged at the front of the shaft body, connecting rods are fixedly arranged at both sides of the balancing block, and a counterweight block is fixedly arranged at one side of the connecting rod away from the balancing block.
[0011] Furthermore, telescopic clamping plates are arranged on both sides of the rear side of the connecting plate, and a stretching handle is fixedly arranged on the rear side of the telescopic clamping plate.
[0012] Furthermore, a portable handle is fixedly provided on the top side of the connecting plate, and an angle dial is provided on the front side of the connecting plate.
[0013] Furthermore, the angle disc is transparent.
[0014] With the above structure, when measuring, first pull open the telescopic card plate on the rear side of the connecting plate through the pulling handle to align the telescopic card plate with the parallel road surface, and compare the balance block on the inner side of the connecting plate with the angle dial to check whether the balance block is balanced. After that, after the measuring mechanism is in the appropriate position in the slotted protrusion on the front side of the scale, the threaded rod is driven by the nut to move backward in the sliding plate, and abuts against the front side of the slotted protrusion, so that the sliding plate cannot slide. Then, the limiting ellipse is rotated and turned out from the opening on one side of the support frame, so that the wire frame continues to output the wire downward. After being brought to the position to be measured by the sinking block, the limiting ellipse is re-stuck in the opening on one side of the support frame to fix the wire frame so that the wire frame cannot rotate to output the wire downward, thereby controlling the length of the wire.
[0015] In summary, the beneficial effects of the utility model are: the balance block and the angle dial in the connecting plate can be used to intuitively check whether the product is balanced, thereby avoiding affecting the measurement accuracy; and through the movable measuring mechanism, the product can be adapted to most venues, improving the measurement accuracy while having strong adaptability.

[0034] Furthermore, the angle dial 3 is transparent, and the scale in the angle dial 3 is opaque, which is more suitable for checking with the balance block 104 whether the installation of this product is in a balanced state.
[0035] With the above structure, when measuring, first pull open the telescopic card plate 8 on the rear side of the connecting plate 1 through the stretching handle 9 to align the telescopic card plate 8 with the parallel road surface, and compare the balancing block 104 on the inner side of the connecting plate 1 with the angle disc 3 to check whether the balancing block 104 reaches balance, then put the measuring mechanism 7 in the slotted protrusion 6 on the front side of the scale 5, and after it reaches the appropriate position, drive the threaded rod 702 to move backward in the sliding plate 701 through the nut 708, and abut against the front side of the slotted protrusion 6, so that the sliding plate 701 cannot slide, and then rotate the limiting ellipse 709 and turn it out from the opening opened on one side of the support frame 705, so that the wire frame 706 continues to output the wire downward, and after being brought to the position to be measured by the sinking block 707, the limiting ellipse 709 is re-stuck in the opening on one side of the support frame 705, and the wire frame 706 is fixed, so that the wire frame 706 cannot rotate to output the wire downward, and the length of the wire can be controlled.
