DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figure 1 and Figure 2 In this implementation: A vertical detection device for construction engineering construction includes a rectangular bottom plate 1. Please refer to Figure 1 , a counterweight 12 is placed on the top of the rectangular bottom plate 1. The function of the counterweight 12 is to lower the center of gravity of the device to prevent the device from tipping over. Universal wheels 13 are installed at the bottom of the rectangular bottom plate 1 to facilitate workers to move the device. The universal wheels 13 are universal wheels with brakes. A lifting structure 2 is installed on the top of the rectangular bottom plate 1. A second circular sleeve 3 is installed on the top of the lifting structure 2. The lifting structure 2 is used to support the second cylindrical sleeve 3 and can adjust the height of the second cylindrical sleeve 3 at the same time. The second circular sleeve 3 is parallel to the side of the rectangular bottom plate 1. A second smooth rod 5 is slidably installed inside the second circular sleeve 3. A horizontal second limit slider 4 is installed on the inner side wall of the second circular sleeve 3. A horizontal second limit chute 6 is provided on the outer side of the second smooth rod 5. The second limit slider 4 is slidably installed in the second limit chute 6. The second smooth rod 5 can slide back and forth inside the second circular sleeve 3. The cooperation between the second limit slider 4 and the second limit chute 6 can limit the rotation of the second smooth rod 5.
[0018] The front end of the second smooth rod 5 is hinged with a rectangular vertical rod 7. The top of the rear side of the rectangular vertical rod 7 is installed with a rectangular cross rod 8. The rectangular vertical rod 7 is perpendicular to the rectangular cross rod 8. A semi-circular plate 9 is installed at the bottom of the rectangular cross rod 8. The semi-circular plate 9 is perpendicular to both the rear side of the rectangular vertical rod 7 and the bottom surface of the rectangular cross rod 8 at the same time. The semi-circular plate 9 is made of transparent plastic. Circumferential scale lines are provided on the semi-circular plate 9. A suspension rope 10 is connected to the bottom of the rectangular cross rod 8 and at the center position of the semi-circular plate 9. The end of the suspension rope 10 is connected to a plumb bob 11. When the front side of the rectangular vertical rod 7 is attached to the wall surface, the rectangular cross rod 8 will be perpendicular to the wall surface. The suspension rope 10 will be vertically downward under the traction of the plumb bob 11. If the wall surface is perpendicular to the ground, the suspension rope 10 will align with the middle scale line on the semi-circular plate 9. If the wall surface is not perpendicular to the ground, the suspension rope 10 will deviate from the middle scale line on the semi-circular plate 9 and align with other scale lines. By reading the scale line aligned by the suspension rope 10, the inclination angle of the wall surface can be roughly obtained.
[0019] Please refer to Figure 2, the lifting structure 2 includes a housing 2-1 which is fixedly installed on the rectangular bottom plate 1. A vertical rotating shaft 2-2 is rotatably installed inside the housing 2-1. A worm gear 2-3 is installed on the rotating shaft 2-2. A worm 2-4 is rotatably installed between the left and right inner side walls of the housing 2-1. One end of the main shaft of the worm 2-4 passes through the inner side wall of the housing 2-1 and a crank 2-11 is installed. The worm 2-4 meshes with the worm gear 2-3. A vertical first cylindrical sleeve 2-5 is installed on the top of the housing 2-1. A first smooth rod 2-7 is slidably installed inside the first cylindrical sleeve 2-5. A second cylindrical sleeve 3 is fixedly installed at the top end of the first smooth rod 2-7. A threaded hole 2-9 is provided at the bottom end of the first smooth rod 2-7. The top end of the rotating shaft 2-2 passes through the top of the inner cavity of the housing 2-1 and a screw rod 2-10 is installed, and the screw rod 2-10 cooperates with the threaded hole 2-9 at the bottom end of the first smooth rod 2-7.

The first limit slider 2-6 is slidably installed in the first limit chute 2-8. By rotating the crank 2-11, the rotation of the worm 2-4 can be controlled. Then, through the meshing of the worm gear 2-3 and the worm 2-4, the screw rod 2-10 on the rotating shaft 2-2 can be driven to rotate. Then, through the cooperation of the screw rod 2-10 and the threaded hole 2-9 at the bottom end of the first smooth rod 2-7, the lifting of the first smooth rod 2-7 can be controlled, so as to adjust the height of the second cylindrical sleeve 3.
[0020] The working principle and usage process of the present utility model: When this vertical detection device for construction engineering construction is used, first adjust the height of the second sleeve 3 as needed, push the device to the side of the wall to be detected, then press the front side of the rectangular bottom plate 1 against the wall and step on the brakes of the universal wheels 13. Push the second smooth rod 5 forward so that the front of the rectangular vertical rod 7 is pressed against the wall as a whole. At this time, the rectangular cross bar 8 is perpendicular to the wall. The suspension rope 10 is vertically downward under the traction of the plumb bob 11. Observe the semi-circular plate 9 and the suspension rope 10. If the suspension rope 10 aligns with the middle scale line on the semi-circular plate 9, the wall is perpendicular to the ground. If the suspension rope 10 deviates from the middle scale line on the semi-circular plate 9, the wall is inclined.
