Description

Technical Field

[0001] This utility model relates to the field of engineering measurement equipment, and in particular to an engineering measurement device. Background Technology

[0002] During engineering construction, it is often necessary to repeatedly measure and calibrate the slope of the ground or slope. Most current slope measuring instruments use two hinged strip plates in conjunction with a protractor to measure angles. When in use, the two strip plates are set up on the slope and the bottom of the slope respectively. The angle between the two strip plates is obtained by reading the angle between the slope and the bottom of the slope through the protractor, and thus the slope of the slope is obtained. However, this slope measuring instrument has the following defects when in use: (1) When in use, the two strip plates must be set up on the slope and the bottom of the slope respectively in order to take a manual reading. However, for some slope structures that are difficult to support on the slope and the bottom of the slope, such as structures with ditches at the junction of the slope and the bottom of the slope, it is difficult to measure; (2) Since the angle between the slope and the bottom of the slope is used to approximate the slope of the slope, the slope measurement result will have a large error when the slope itself has a certain angle. Utility Model Content

The output shaft of the second rotary drive device is fixedly connected to the telescopic device. The second rotary drive device is used to drive the telescopic device to rotate within the vertical interface. A distance measuring device is provided at the end of the telescopic device away from the second rotary drive device. The controller is connected to the second rotary drive device and the telescopic device respectively, and the controller is also connected to the ranging device via signal. An energy storage device is installed on the rotating platform, and the energy storage device is electrically connected to the controller.

[0005] Preferably, the top of the rotary table is provided with a first mounting groove with an upper opening, and a second rotary drive device is fixedly mounted on the side wall of the first mounting groove. When the telescopic device is retracted to its shortest length, it can be rotated and driven into the first mounting slot by the second rotary drive device. The top of the first mounting slot is provided with a removable cover plate, and the top of the cover plate is provided with a handle.

[0006] Preferably, a level bubble is provided on the top of the rotary table.

[0007] Preferably, the bottom of the base is provided with a plurality of height adjustment devices arranged in a circumferential manner at equal intervals, the height adjustment devices being used to adjust the height between the bottom of the base and the ground.

[0008] Preferably, the height adjustment device is a pneumatic cylinder or a hydraulic cylinder, and the controller is connected to multiple height adjustment devices respectively.

[0014] The advantages of this invention are: When using this device, there is no need to specifically place it against the bottom of the slope. It only needs to be placed directly in front of the area of ​​the slope to be measured. The controller adjusts the raising and lowering of the telescopic device, allowing the measuring device to measure multiple horizontal distances to the slope. Then, based on preset Pythagorean theorem and inverse trigonometric function formulas, the controller automatically calculates the angle between the slope and the horizontal plane, which is the slope gradient. This greatly improves the convenience and accuracy of measurement.

[0015] Meanwhile, the mounting platform and the base are rotatably connected, and the height adjustment device installed at the bottom of the base means that the measuring device does not need to be specially positioned when placed. After placement, the mounting platform will tilt, and the level of the mounting platform can be adjusted by the height adjustment device. Then, during measurement, the measuring end of the measuring device can be oriented towards the slope to be measured by rotating the mounting platform.

[0016] This measuring device can measure not only slopes that extend in a straight line, but also slopes that extend in a ring at the same location. In addition, this device can also be applied to the field of wall verticality measurement. Attached Figure Description

The height adjustment devices 2 are used to adjust the height between the bottom of the base 1 and the ground. The height adjustment devices 2 can be pneumatic or hydraulic cylinders; in this embodiment, pneumatic cylinders are used. A controller 14 is connected to each of the multiple height adjustment devices 2. Anti-slip pads 3 are fixedly provided at the bottom of each height adjustment device 2.

[0021] The base 1 is equipped with a rotating platform 4 on top, and the rotating platform 4 is equipped with a level bubble 13 and a controller 14 on top.

[0022] A first rotation drive device 5 is embedded in the bottom of the rotary table 4. In this embodiment, the first rotation drive device 5 is a geared motor. The lower end of the output shaft of the first rotation drive device 5 is fixedly connected to the base 1, and the first rotation drive device 5 is controlled by the controller 14. The rotary table 4 is driven to rotate relative to the base 1 by the first rotation drive device 5.

[0023] To reduce the pressure on the output shaft of the first rotary drive device 5, a number of rotatable ball bearings 6 arranged in a ring at intervals are embedded in the top of the base 1, such as... Figure 1 and Figure 2 As shown, the top of the ball 6 makes rolling contact with the bottom of the rotary table 4.

[0024] The top of the rotary table 4 has a first mounting groove 401 with an upper opening. A second rotary drive device 7 is fixedly mounted on the side wall of the first mounting groove 401. In this embodiment, the second rotary drive device 7 is a servo motor. The output shaft of the second rotary drive device 7 is fixedly connected to the telescopic device 8. The second rotary drive device 7 is used to drive the telescopic device 8 to rotate within the vertical interface. In this embodiment, the telescopic device 8 is a cylinder. In other embodiments, the telescopic device 8 can also be replaced by a hydraulic rod or an electric push rod. The end of the telescopic device 8 away from the second rotary drive device 7 is provided with a mounting sleeve 9. A ranging device 10 is detachably inserted into the mounting sleeve 9. In this embodiment, the ranging device 10 is a ranging sensor.

[0025] When the telescopic device 8 is retracted to its shortest length, the telescopic device 8 and the ranging device 10 can be rotated and driven into the first mounting slot 401 by the second rotary drive device 7; the top of the first mounting slot 401 is provided with a detachable cover plate 11, and the top of the cover plate 11 is provided with a handle 12.

[0026] A second mounting slot 402 is provided on the side wall of the rotary table 4. An energy storage device is installed in the second mounting slot 402. In this embodiment, the energy storage device includes an inverter 16 and a battery 15. A sealing plate 17 is provided at the opening of the second mounting slot 402. A charging port 18 is embedded in the sealing plate 17. The charging port 18 is electrically connected to the inverter 16. The inverter 16 is electrically connected to the battery 15. The battery 15 is electrically connected to the controller 14.

[0027] The controller 14 is connected to the height adjustment device 2, the first rotary drive device 5, the second rotary drive device 7, and the telescopic device 8, respectively, and is also connected to the ranging device 10 via signal. In this embodiment, the controller 14 is a PLC controller.

[0028] To facilitate the transport of this measuring device, such as Figure 1 and Figure 2 As shown, a handle 19 is fixedly provided on the side wall of the rotating platform 4.

[0029] Working principle: When in use, the surveyor uses the handle 19 to transport the measuring device to any position at the bottom of the slope to be measured. Then, the measuring device is placed flat on the ground. By observing the bubble level 13, if the rotating platform 4 is not horizontal, the controller 14 controls one or more of the height adjustment devices 2 in the tilted position to raise or lower, while observing the bubble level 13, until the rotating platform 4 is horizontal.

[0030] Then, open the cover plate 11, and control the second rotary drive device 7 to rotate via the controller 14, as follows. Figure 4 As shown, the telescopic device 8 is then flipped upwards to a vertical 90-degree position. Then, the controller 14 controls the first rotation drive device 5 to rotate, thereby driving the rotating table 4 to rotate, so that the measuring end of the measuring device 10 on the telescopic device 8 faces the slope direction.

[0031] The controller 14 controls the ranging device 10 to perform the first distance measurement, and obtains the first horizontal distance value a with respect to the slope. Then, the telescopic device 8 is raised by a length of b through the controller 14, and the distance measuring device 10 is controlled by the controller 14 to perform a second distance measurement to obtain the first horizontal distance value c with the slope. The controller 14 can automatically calculate the angle between the slope and the horizontal plane, which is the slope, based on the preset Pythagorean theorem formula and inverse trigonometric function formula.

[0032] Based on the above method, the telescopic device 8 is raised and lowered multiple times to obtain multiple angle values ​​between the slope and the horizontal plane. Then, the average angle value of the multiple angle values ​​is calculated, which is the slope of the slope.

[0033] Example 2: An engineering measuring device. The difference between this example and Example 1 is that the second rotary drive device 7 and the energy storage device are both located on the top of the rotary table 4, and the first mounting slot 401 and the second mounting slot 402 are not provided on the rotary table 4.

[0034] The first rotation drive device 5 is no longer installed on the rotary table 4, and the rotary table 4 and the base 1 are rotatably connected by a rotating shaft.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
