Description

Technical Field

[0001] This invention relates to the field of construction management equipment technology, and more particularly to a measuring device for construction management. Background Technology

[0002] In actual construction management scenarios, surveying operations often face diverse and complex terrains, such as mountain slopes, muddy depressions, undulating foundation pit edges, and rocky field sites. These uneven and unstable terrain conditions place stringent demands on the adaptability of surveying equipment, and the limitations of existing equipment are particularly prominent when dealing with such environments, becoming a key bottleneck restricting surveying efficiency and accuracy.

[0003] Patent publication number CN221723879U discloses an intelligent measuring device for water conservancy construction management, including a base. Multiple first fixing blocks are fixedly mounted on the bottom end of the base. First limiting posts are fixedly mounted on the inner sides of each of the first fixing blocks. Connecting rods are rotatably mounted on the outer sides of each of the first limiting posts. Sliding rods are slidably mounted inside each of the connecting rods. Second fixing blocks are fixedly mounted on the bottom ends of each of the sliding rods. Second limiting posts are fixedly mounted on the inner sides of each of the second fixing blocks. In this invention, the first fixing blocks are installed at the bottom end of the base, and the first limiting posts are installed inside the first fixing blocks. This allows for convenient rotation of the connecting rods during use, and the connecting rods also provide convenient support for the base. The height of the base can be adjusted by changing the position of the sliding rods, preventing excessive outward expansion of the connecting rods.

[0004] Although the above-mentioned multi-angle adjustment is achieved through multiple limiting posts and fixing seats, in actual use, fixing the measuring device with only the fixing cone cannot adapt to the diversity of terrain. For example, when facing some hard geological conditions that the fixing cone cannot penetrate, fixing the measuring device with the fixing cone will affect the measurement accuracy. Summary of the Invention

[0005] To address the above problems, the present invention provides a measuring device for construction management.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A measuring device for construction management includes a measuring platform, wherein the measuring platform is provided with an adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a connecting rod, which is connected to a support seat via a first bearing. The connecting rod is provided with a sliding groove, and the support seat is connected to a measuring platform.

[0009] Preferably, the slide is slidably connected to a fixed base via a second bearing. The fixed base is equipped with a negative pressure suction cup and a vacuum pump, and the output end of the vacuum pump is connected to the negative pressure suction cup.

[0010] Preferably, the connecting rod is equipped with an electromagnetic coil, and both the first bearing and the second bearing are equipped with electromagnets.

[0011] Preferably, the connecting rod has a fixing head on the side away from the support base.

[0012] Preferably, the measuring platform is provided with an angle measuring disk on the side away from the support base.

[0013] Preferably, the measuring platform is connected to the support platform via a rotating shaft, and the outer wall of the rotating shaft is provided with a steering pointer.

[0014] Preferably, a measuring instrument is provided on the support platform, and a protective shell is provided around the support platform in a ring shape.

[0015] Preferably, the bottom of the measuring platform is equipped with an electric telescopic rod, one end of which is connected to the drill bit.

[0016] Preferably, the vacuum pump, connecting rod, first bearing, and second bearing are all connected to an external power source.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This application provides a sliding groove on the connecting rod, and a fixed base is slidably connected to the sliding groove via a second bearing. A negative pressure suction cup is provided at the bottom of the fixed base. The air pressure between the negative pressure suction cup and the contact surface is adjusted by a vacuum pump connected to the negative pressure suction cup, so that the negative pressure suction cup can be stably fixed on the contact surface. Compared with the prior art, this application adds a negative pressure suction cup fixing method to the fixing head to avoid situations where the fixing head faces some hard surfaces that cannot be penetrated.

[0019] 2. By installing electromagnetic coils and electromagnets inside the connecting rod, the first bearing, and the second bearing, the electromagnetic coils and electromagnets attract each other when an external power source is applied, thereby fixing the connecting rod, the first bearing, and the second bearing. This prevents the measuring instrument from shaking during operation, which could lead to a decrease in measurement accuracy. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example 1

[0030] Please see Figures 1-5 As shown, the present invention relates to a measuring device for construction management, specifically including: a measuring table 1, wherein the surface of the measuring table 1 is provided with an angle measuring disk 10;

[0031] Specifically, an adjustment mechanism is provided at the bottom of the measuring platform 1. The adjustment mechanism includes a connecting rod 2, which is connected to the support base 4 through a first bearing 3. The connecting rod 2 is provided with a sliding groove 5, and the support base 4 is connected to the measuring platform 1.

[0032] Specifically, the connecting rod 2 is equipped with an electromagnetic coil, and the first bearing 3 and the second bearing 18 are both equipped with electromagnets. The connecting rod 2, the first bearing 3 and the second bearing 18 are all connected to the same external power source.

[0033] Specifically, when the connection between connecting rod 2 and the first bearing 3, and the connection between connecting rod 2 and the second bearing 18 are provided with an air gap of 0.2-0.5mm, when the connection between connecting rod 2 and the first bearing 3, or the connection between connecting rod 2 and the second bearing 18, is energized in the same direction, the magnetic field is enhanced, and the connection state of the connection between connecting rod 2 and the first bearing 3, or the connection state of connecting rod 2 and the second bearing 18, is locked; when the connection between connecting rod 2 and the first bearing 3, or the connection between connecting rod 2 and the second bearing 18, is energized in opposite directions, the magnetic field cancels out, and the connection state of the connection between connecting rod 2 and the first bearing 3, or the connection state of connecting rod 2 and the second bearing 18, is locked.

[0034] Furthermore, the connecting rod 2 of this application adopts a telescopic design to adjust the different height positions of the measuring device.

[0035] Specifically, the slide groove 5 is slidably connected to the fixed base 6 via the second bearing 18. The fixed base 6 is equipped with a negative pressure suction cup 7 and a vacuum pump 8. The output end of the vacuum pump 8 is connected to the negative pressure suction cup 7. The vacuum pump 8, which is connected to the negative pressure suction cup 7, adjusts the air pressure between the negative pressure suction cup 7 and the contact surface, so that the negative pressure suction cup 7 can be stably fixed on the contact surface. Compared with the prior art, this application adds a negative pressure suction cup 7 fixing method to the fixing method of the fixing head 9, so as to avoid the fixing head 9 facing some hard ground that cannot be penetrated.

[0036] Specifically, an electric telescopic rod 16 is provided at the bottom of the measuring platform 1, with one end of the electric telescopic rod 16 connected to a drill bit 17. Through the connection between the electric telescopic rod 16 and the drill bit 17, the operator can fix the measuring device at different heights, thereby improving the stability of the measuring device.

[0037] Furthermore, the fixed angle of the fixed base 6 can be adjusted by the second bearing 18 to adapt to different terrains.

[0038] Specifically, the vacuum pump 8, connecting rod 2, first bearing 3 and second bearing 18 are all connected to an external power source. By connecting to an external power source, when it is necessary to adjust the angle of the measuring device, the fixed connection between the connecting rod 2 and the first bearing 3 and the second bearing 18 is simultaneously released by cutting off the power of the external power source, which makes it convenient for the operator to adjust the angle of the measuring device.

[0039] refer to Figure 6 As shown, specifically, when the measuring device needs to be placed on a flexible surface, such as a muddy or sandy surface, there is no need to slide the fixed base 6. The measuring device is fixed by inserting the fixing head 9 on the connecting rod 2 into the ground.

[0040] In some embodiments, the fixing head 9 may have any shape, including but not limited to circular and conical shapes.

[0041] Specifically, the measuring platform 1 is connected to the support platform 12 via a rotating shaft 11. The outer wall of the rotating shaft 11 is provided with a steering pointer 13. The support platform 12 is provided with a measuring instrument 14, and a protective shell 15 is provided in a ring around the support platform 12.

[0042] Specifically, the protective shell 15 adopts a double-layer roll design. The protective shell 15 is opened according to the orientation of the measuring instrument 14 to avoid obstructing the view of the measuring instrument 14. At the same time, the other areas of the protective shell 15 are in a shielded state to protect the measuring instrument 14.

[0043] Example 2

[0044] Based on the description in Example 1, in this example, a miniature electric drill bit 17 is set to replace the fixed head 9 and the drill bit 17. The drill bit 17 is started by an external power source, so that the miniature electric drill bit 17 can be better fixed to the ground. The miniature electric drill bit 17 can reduce the manpower required for fixing.

[0045] Furthermore, a fixing mechanism is provided on the slide groove 5, wherein the sliding fixing mechanism is used to fix the fixing base 6 on the slide groove 5, so as to prevent the fixing base 6 from sliding on the slide groove 5 when it is not needed, thereby affecting the stability of the measuring device.

[0046] Furthermore, a high-precision reference sphere is installed on the bearing platform 12, and a global coordinate system is formed by calibration using a total station;

[0047] A coordinate system is formed by laser-etched grid lines on the surface of the support platform 12, and conductive ink is printed on it. The position change of the measuring instrument 14 can be detected by the conductive ink printing. A conductive stylus array is provided at the bottom of the measuring instrument 14. When the stylus contacts the grid, it forms a parallel circuit and changes the local resistance value.

[0048] An XY guide rail is set on the coordinate system, and an encoder grating ruler is integrated on the XY guide rail. A sensor module, such as a laser displacement sensor, is set on the bearing platform 12 to further detect the position and offset of the measuring instrument 14 on the coordinate system.

[0049] Furthermore, the measuring device of this application communicates with a terminal via a wireless module. The terminal can observe the measuring angle of the measuring instrument 14 and its position coordinates on the support platform 12 in real time, thereby improving the measurement accuracy of the measuring device based on the recorded data.

[0050] Furthermore, a clamping mechanism is also provided on the support platform 12. The specific clamping mechanism includes electric clamping plates located on both sides of the support platform 12. The electric clamping plates adopt a flexible structure to avoid damage to the measuring instrument 14.

[0051] Example 3

[0052] Based on the above embodiments, the working principle of this application can be derived as follows:

[0053] Before use, place the measuring instrument 14 on the support platform 12 and fix it. Rotate the support platform 12 to adjust the measuring angle according to the measurement needs. Select appropriate fixing parts according to the terrain of the area to be measured by the measuring device.

[0054] When it is necessary to fix the measuring device on a flexible ground, turn on the external power supply so that the connecting rod 2, the first bearing 3 and the second bearing 18 are energized in the same direction, that is, the connecting rod 2, the first bearing 3 and the second bearing 18 are in a movable connection state, which makes it convenient for the operator to adjust the position of the connecting rod 2. After the adjustment is completed, insert the fixing ball on the connecting rod 2 into the ground to fix the measuring device, and then pass in the reverse current so that the connecting rod 2, the first bearing 3 and the second bearing 18 are in a fixed connection state. According to the orientation of the measuring instrument 14, open the protective shell 15 to avoid obstructing the view of the measuring instrument 14. At the same time, the other areas of the protective shell 15 are in a shielding state to protect the measuring instrument 14.

[0055] Furthermore, by extending and retracting the electric telescopic rod 16 at the bottom of the measuring platform 1, the drill bit 17 is driven to insert into the ground, allowing the operator to fix the measuring device at different heights, thereby further improving the stability of the measuring device.

[0056] When it is necessary to fix the measuring device on a rigid ground, the external power supply is turned on by the fixed base 6 on the sliding groove 5, so that the connecting rod 2, the first bearing 3 and the second bearing 18 are in the same direction of power supply, that is, the connecting rod 2, the first bearing 3 and the second bearing 18 are in a movable connection state, which makes it convenient for the operator to adjust the position of the connecting rod 2. After the adjustment is completed, the vacuum pump 8 is turned on to adjust the air pressure between the negative pressure suction cup 7 and the ground, so that the fixed base 6 is in stable contact with the ground, thereby fixing the measuring device. According to the orientation of the measuring instrument 14, the protective shell 15 is opened to avoid obstructing the view of the measuring instrument 14. At the same time, other areas of the protective shell 15 are in a shielding state to protect the measuring instrument 14.

[0057] During measurement, the measuring angle of the measuring instrument 14 is adjusted by rotating the bearing platform 12, and the rotation angle of the measuring instrument 14 is recorded by the direction pointer 13 to improve the measurement accuracy.
