Problems solved by technology

[0003] When the wedge-shaped feeler gauge is inserted into the largest gap, it is necessary to ensure that the wedge-shaped surface of the wedge-shaped feeler gauge is in contact with the detection ruler above it, so as to push the vernier on the wedge-shaped feeler gauge, but it is very easy to push the wedge-shaped feeler gauge and the detection ruler at the same time The detection ruler makes the detection ruler deviate from the original position, resulting in inaccurate detection results, and the method of visual observation to determine the maximum gap is also prone to large errors, that is, the maximum gap determined by the human eye does not have complete authenticity, not necessarily It is the real biggest gap, and the workers have to carry out the smoothness inspection of multiple road sections a day, select multiple test positions on each road section, and test the multiple test positions one by one, and each time they squat down and observe with their eyes, it intensifies the The workload of the workers is very prone to the phenomenon of eye fatigue, and the above phenomenon will further increase the error; when testing the wall, in addition to the above problems, because the detection ruler is long (closed length 1 meter, unfolded 2 meters long), one person needs to press the detection ruler to prevent the detection ruler from detaching from the wall, and one person uses a wedge-shaped feeler gauge to measure the largest gap, which increases labor costs

Embodiment 1

[0028] Embodiment 1, a multi-performance detection device for building engineering construction, including a detection ruler 1, a plurality of distance measuring mechanisms uniformly distributed along the front and rear directions on the detection ruler 1, and the distance measurement mechanism includes vertically arranged on the detection ruler 1 Screw 2, there is a cam push rod 4 that is slidingly matched with the spiral groove on the screw rod 2 on the detection ruler 1, the cam push rod 4 is placed on the left side of the screw rod 2 and placed under the thread groove on the screw rod 2, and the screw rod 2 is equipped with There is a through hole 5 coaxial with the screw 2, and there is a probe rod 6 coaxial with the screw 2 in the through hole 5, the lower end of the screw 2 is coaxially rotated and connected with a swivel 7, and the lower end of the probe 6 passes through the center of the swivel 7 From the hole to the bottom of the swivel 7, the lower end surface of the...

Embodiment 2

[0030] Embodiment 2, on the basis of Embodiment 1, the cantilever 15 is provided with a mounting groove placed directly above the connecting end of the ring 14 and the wire rope 16, the mounting groove runs through the cantilever 15 downwards, and the cantilever 15 is placed on the The delay mechanism in the installation groove, the delay mechanism includes the incomplete gear 19 that is rotatably connected on the cantilever 15, the axis of the incomplete gear 19 is arranged along the front and back direction, and the incomplete gear 19 is placed on the right side of the wire rope 16 in the cantilever 15, On the incomplete gear 19, there is a clip 20 in contact with the wire rope 16 in the cantilever 15. The clip 20 is placed at the bottom of the incomplete gear 19 and the clip 20 is inclined to the lower left. The vertical third rack 21 on the right side of the gear 19 and meshed with the incomplete gear 19 is vertically slidably connected between the third rack 21 and the can...

Embodiment 3

[0032] Embodiment 3. On the basis of Embodiment 1, the transmission mechanism includes a vertical fourth rack 25 connected to the left end of the cantilever 15 and placed below the cantilever 15. The detection ruler 1 is rotatably connected with The first transmission gear 26 meshed with the fourth rack 25, the first transmission gear 26 is coaxially connected with the second transmission gear 27, and the detection scale 1 is rotatably connected with the third transmission gear 28 meshed with the second transmission gear 27, The index circle diameter of the third transmission gear 28 is less than the index circle diameter of the second transmission gear 27, and the third transmission gear 28 is coaxially connected with the corresponding dial 17, because the depth of the concave part of the measured surface is generally Not too deep, the maximum distance that the rack moves down is the depth of the concave part. At this time, the rotation angle of the first transmission gear 26 ...

Abstract

The invention discloses a multi-performance detection device for building engineering construction, when a worker uses the multi-performance detection device, the worker holds a detection ruler by hand to enable the bottom surface of the detection ruler to cling to a wall surface, then a motor is turned on, the motor is turned off after a period of time, and the flatness value of the wall surface can be obtained by reading through an observation hole. The device is simple and convenient in use, the error of measured values is lower than that of an existing extensible detection ruler, the detection ruler does not need to be used together with a wedge-shaped filler gauge, the use amount of tools is reduced, the labor cost is reduced, the overall operation resistance is reduced through the design that the screw rod slides back and forth under the action of the first spring, pressing by workers is facilitated, and the burden of the workers is relieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering detection, in particular to a multi-function detection device for construction of construction engineering. Background technique [0002] In the inspection of construction projects, it is often necessary to inspect the flatness of walls and roads. However, the existing flatness inspection device is mainly based on an expandable inspection ruler. When inspecting the road surface, first put the inspection ruler straight On the road surface, then determine the position of the largest gap between the detection ruler and the road surface by visual observation, insert the wedge-shaped feeler gauge into the above-mentioned largest gap, and measure the distance of the largest gap through the wedge-shaped feeler gauge. [0003] When the wedge-shaped feeler gauge is inserted into the largest gap, it is necessary to ensure that the wedge-shaped surface of the wedge-shaped feeler gauge is in ...
