Abstract
Description
Technical Field
[0001] This utility model relates to the field of trench measurement technology, and in particular to a trench laser measurement device. Background Technology
[0002] In civil engineering, road construction, and underground pipeline laying, accurate trench measurement is crucial for ensuring construction quality. The dimensional parameters of the trench (such as width, depth, and inclination angle) directly affect the stability and safety of subsequent works. Traditional trench measurement methods mainly rely on manual measurement using tools such as measuring tapes and levels for single-point measurements. This method is not only inefficient but also makes it difficult to obtain full-section data of the trench, especially in complex terrain or confined spaces, where measurement accuracy and operability are severely limited.
[0003] In existing technologies, some automated measuring devices scan trenches using laser ranging or image recognition technology, but these devices can typically only acquire measurement data from a single angle. Furthermore, the trench environment often presents problems such as unevenness and obstructions, causing the measuring device to be unable to stably position itself or cover the entire area to be measured. Therefore, we propose a trench laser measuring device capable of multi-angle measurement. Utility Model Content

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] This utility model provides, for example Figures 1-2 The image shows a groove laser measurement device.
[0033] Example 1: Includes a vehicle body 101, a measuring mechanism, a first adjusting mechanism, a second adjusting mechanism, and a third adjusting mechanism. The measuring mechanism has multiple sets, with three sets connected to the vehicle body 101. The first adjusting mechanism adjusts the height of the measuring mechanism, the second adjusting mechanism adjusts the angle of the measuring mechanism, and the third adjusting mechanism extends the measuring mechanism into the trench. The vehicle body 101 moves the measuring mechanism to the edge of the trench, and then the third adjusting mechanism moves the measuring mechanism to the trench position. The first and second adjusting mechanisms then adjust the height and angle of the three measuring mechanisms, allowing for multi-angle measurements of the trench using the three sets of measuring mechanisms, thus improving the diversity of trench measurement data. The vehicle body 101 is a tracked mobile vehicle, enabling stable movement along the trench edge. A GPS module is also installed inside the vehicle body 101, using a GPS positioning device to measure the trench position in real time, record the running trajectory, and form a complete data chain with other trench measurement data, providing continuous position information for subsequent data calculations.
[0034] The measuring mechanism includes a laser rangefinder 201, which is connected to the first adjustment mechanism. Laser ranging can be performed in the trench by the operation of the laser rangefinder 201.
[0035] The first adjustment mechanism includes a connecting seat 301 and a slider 302, with multiple connecting seats 301 fixedly connected to each other. A third adjustment mechanism is located between the connecting seat 301 and the vehicle body 101. The slider 302 is slidably disposed inside the connecting seat 301, and a fixing plate 303 is fixedly connected to one side of the slider 302. The second adjustment mechanism is located between the fixing plate 303 and the laser rangefinder 201. A moving mechanism is provided between the slider 302 and the connecting seat 301, and the moving mechanism includes a lead screw 402 rotatably connected to the connecting seat 301. Inside the connector 1, the top of the slider 302 has a threaded hole, and the outer wall of the lead screw 402 is threadedly connected to the inner wall of the threaded hole. The servo motor 403 is installed inside the connecting seat 301. The output end of the servo motor 403 is connected to the top of the lead screw 402. The servo motor 403 can drive the lead screw 402 to rotate by working. Through the threaded engagement between the outer wall of the lead screw 402 and the inner wall of the threaded hole, the slider 302 can be driven to rise and fall, thereby driving the laser rangefinder 201 to rise and fall, thus adjusting the height of the laser rangefinder 201.
[0036] The second adjustment mechanism includes a second connecting plate 502, a third connecting plate 503, and a first electric telescopic rod 504. The second connecting plate 502 is fixedly connected to one side of the fixed plate 303. One end of the laser rangefinder 201 is fixedly connected to the first connecting plate 501, and the first connecting plate 501 and the second connecting plate 502 are rotatably connected. The top end of the first electric telescopic rod 504 is fixedly connected to a fourth connecting plate 505. The outer wall of the fixed plate 303 is fixedly connected to a fifth connecting plate 506, and the fifth connecting plate 506 and the fourth connecting plate 505 are rotatably connected. The third connecting plate 503 is fixedly connected to the output end of the first electric telescopic rod 504, and the third connecting plate 503 and the first connecting plate 501 are rotatably connected. By operating the first electric telescopic rod 504, the laser rangefinder 201 can rotate around the rotatable connection between the second connecting plate 502 and the first connecting plate 501, thereby adjusting the measurement angle of the laser rangefinder 201.
[0037] Example 2: Compared to Example 1, the third adjustment mechanism includes a fixed base 601 and a second electric telescopic rod 603. The fixed base 601 is fixedly connected to one side of the vehicle body 101, and a top plate 602 is fixedly connected to one side of the fixed base 601. The second electric telescopic rod 603 is installed at the bottom of the top plate 602. The output end of the top plate 602 is connected to the top end of the connecting seat 301. A limit mechanism is provided between the top plate 602 and the connecting seat 301. By operating the second electric telescopic rod 603, multiple connecting seats 301 can be raised and lowered, thereby moving the connecting seats 301 to the groove position for easy measurement by the laser rangefinder 201. The second electric telescopic rod 603, the first electric telescopic rod 504, the servo motor 403, and the laser rangefinder 201 are electrically connected to an external power supply through external switches, which facilitates the operator to control them separately, thereby improving the safety and convenience of operation.
[0038] The limiting mechanism includes a limiting guide rod 701, the bottom end of which is fixedly connected to the top end of the connecting seat 301. A limiting guide hole 702 is provided at the top end of the top plate 602. The limiting guide rod 701 is movably inserted into the inner wall of the limiting guide hole 702. Through the mutual limiting of the limiting guide rod 701 and the limiting guide hole 702, when the second electric telescopic rod 603 drives the connecting seat 301 to rise and fall, the connecting seat 301 can move steadily up and down, thereby improving the stability of the third adjustment mechanism.
[0039] like Figure 3The diagram shows the distances measured by the three measuring mechanisms of the groove laser measuring device of this invention. The laser rangefinders 201 of the three measuring mechanisms measure three distances, and then calculate key data such as the groove depth, width, and slope according to corresponding mathematical formulas. For example, the groove depth and slope are calculated by using trigonometric relationships, combined with the angle of the laser beam and the measured distance; the groove width is obtained by analyzing the laser ranging data from different locations.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
