DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Such as Figures 1 to 5As shown in the figure, a device height detection device includes a base 1, floor anchor nails 2, a benchmark 3, a sliding rod 4, an indicating rod 5, a connecting rod 6, an end rod 7, and a plumb bob assembly 8. The lower part of the base 1 is in contact with the ground through the floor anchor screws 2. The base 1 is the center of gravity of the entire device, which plays a role of counterweight while providing support to prevent the device from tipping over. The floor anchor nails 2 are installed at the lower part of the base 1 to fine-tune the entire device, making the entire device vertical and stable. A benchmark 3 is vertically erected on the base 1. Scale lines 9 are provided on the benchmark 3. The scale lines 9 are 800 small grids at the upper end of the benchmark. Each small grid is 1 mm, and the starting 0 scale line is upward. According to the similarity ratio, the actual height can be marked and gradually decreased. The upper end of the benchmark 3 is rotatably connected to the indicating rod 5. An indicating edge 10 is provided at the lower end of the indicating rod 5. The indicating edge 10 is located on the center line of the indicating rod 5 to ensure the accuracy of measurement. A sliding rod 4 is slidably connected to the middle part of the benchmark 3. The sliding rod 4 cooperates with the benchmark 3 to slide through a chute 11. A small scale 12 is provided at the chute 11, and the graduation value is 0.02 mm, making the measurement more accurate. The connecting rod 6 is threadedly connected to the upper end of the indicating rod 5. The connecting rod 6 is designed as a multi-section combination, which is convenient for handling and storage. It is spliced through the stud 13 and threaded hole 14 with M12 at the head and tail. The end rod 7 is threadedly connected to the upper end of the connecting rod 6.

Embodiment

[0022] When the device is used to detect the height of the equipment, first assemble the base 1, floor anchor nails 2, benchmark 3, sliding rod 4, indicating rod 5, connecting rod 6, end rod 7, and plumb bob assembly 8, and place them at an appropriate distance on the same horizontal plane of the equipment to be measured, so that the plumb bob 803 is near the highest point of the equipment, as Figure 6 shown.

[0023] The dimensions of the detection device are set as follows: the measuring range is 1.2 m - 6 m, the similarity ratio of the triangle is 1:7, the ratio dimensions of the small triangle are 600 mm, 800 mm, and 1000 mm for the classic right triangle, and the actual measurement size can be accurate to the tenth place, as Figure 7 shown.

[0024] Use a level ruler to fit the base 1, and use the anchor screws to fine-tune the base 1 to make the base 1 horizontal, and keep the benchmark 3 and the base 1 vertical. Then, hold the indicator rod 5 with your right hand, rotate it up and down, place the tip of the plumb bob 803 of the pendant assembly 8 on the highest point of the object to be measured, and gently touch it to keep the steel wire taut and vertical. After the plumb bob 803 is still, keep your right hand still, and adjust the position of the slide bar 4 with your left hand until the slide bar 4 is tangent to the indicating edge 10 of the indicator rod 5. Read the scale line 9 on the benchmark 3 in conjunction with the small scale 12 on the slide bar 4. The actual height is "6m-reading × 7".

[0025] At this time, the scale line 9 of the benchmark 3 and the small scale 12 on the slide bar 4 read zero, and "6m-×7" is the actual height of 6m. Here, the data can also be directly converted to the direct reading on the benchmark, which can more conveniently and quickly obtain the actual height value.

[0026] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
