[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , a height measurement device of this embodiment includes an infrared rangefinder 1.

[0024] The working principle of the infrared rangefinder 1 is basically to use the characteristics of infrared laser for measurement. Generally speaking, the infrared rangefinder 1 includes an infrared laser transmitter and a receiver, and its working principle is as follows:

[0025] Emitting infrared laser: The infrared rangefinder 1 generates a beam of infrared laser through a laser transmitter, and this laser is irradiated onto the target object.

[0026] Receiving reflected signals: Once the laser is irradiated onto the target object, it will be reflected or scattered by the target object, and the receiver will receive these reflected or scattered laser signals.

[0027] Calculating distance: The receiver measures the time delay of the laser signal and determines the round-trip time of the laser by calculating the time from the laser being emitted to being received. Then, based on the speed of light and the round-trip time, the distance between the target object and the rangefinder can be calculated.

[0028] A rotating adjustment seat 3 is installed on the lower surface of the infrared rangefinder 1. A level bubble ball 4 is installed on the front surface of the rotating adjustment seat 3. The lower surface of the rotating adjustment seat 3 is rotatably connected to a horizontal adjustment seat 2. A plurality of threaded lifting seats 15 are provided at the bottom of the horizontal adjustment seat 2.

[0029] The threaded lifting seat 15 is composed of a screw rod and a nut.

[0030] As the screw rotates, the threaded screw creates a thrust force inside the nut, which causes the nut to move along the axis of the screw. If the screw is fixed and the nut is free to turn, the nut will move along the axis of the screw. Conversely, if the nut is fixed and the screw is free to turn, the screw will move along the axis of the nut.

[0031] In this embodiment, a lifting regulator for adjusting the height is installed on the rotating adjustment seat 3.

[0032] It should be noted that the lifting and lowering adjuster includes a telescopic rod 5 inserted into the top of the rotating adjustment seat 3, a micro motor 6 installed on the top of the telescopic rod 5, a laser receiving plate 7 installed at the output shaft of the micro motor 6, an electric push rod 8 installed on the upper surface of the laser receiving plate 7, and a movable positioning block 9 installed at the push rod of the electric push rod 8.

[0033] The telescopic rod 5 is composed of a plurality of sealed hollow cylinders that are slidably connected to each other. The inside and outside of the sealed hollow cylinders are both covered with sealing rubber to ensure the sealing of the connection and avoid air leakage. Among them, the bottom sealed hollow cylinder is connected to the rotating adjustment seat 3, and the top sealed hollow cylinder is connected to the micro motor 6.

[0034] The lower surface of the laser receiving plate 7 is aligned with the lower surface of the movable positioning block 9 .

[0035] It is ensured that when the mobile positioning block 9 is set on the top of the measurement target, the lower surface of the laser receiving plate 7 is aligned with the measurement target, thereby improving the accuracy of the measurement height.

[0036] The lifting regulator in this embodiment is provided with a fixture for fixing the lifting regulator after it is shrunk. The fixture includes a straight rod 11 installed on the outside of the bottom sealed hollow cylinder, an iron block 10 installed on the outside of the micro motor 6, and an electromagnet 12 installed on the upper surface of the straight rod 11 and fixed to the iron block 10 by adsorption.

[0037] An outer cover is installed outside the micro motor 6 , and the micro motor 6 is connected to the iron block 10 through the outer cover.

[0038] When the telescopic rod 5 is in the retracted state, the electromagnet 12 contacts the iron block 10 and is energized to adsorb the iron block 10 so as to stow the telescopic rod 5 and fix it for easy transfer.

[0039] The lift regulator in this embodiment is connected to an air intake and exhaust assembly.

[0040] The air intake and exhaust assembly controls the lifting and lowering of the lift regulator by charging and exhausting air into the lift regulator.

[0041] It should be noted that the air intake and exhaust assembly includes a portable sealing cylinder 13, a push rod 14 is installed on the top of the portable sealing cylinder 13, an air pipe 17 is connected between the portable sealing cylinder 13 and the bottom sealed hollow cylinder, and the outside of the air pipe 17 is connected to a switch valve 16 (the switch valve 16 is a three-way valve, which is closed to allow the air pipe 17 to be connected, and opened to allow the air pipe 17 to be connected to the outside, which can be used for deflation). The inflation principle of the portable sealing cylinder 13 is the same as that of the current air pump, so its structure and principle will not be elaborated on.

[0042] The working principle is as follows: the horizontal adjustment seat 2 and the rotation adjustment seat 3 are provided to facilitate rotation and up and down angle adjustment, and the level bubble ball 4 provided is adjusted to the center by observation, so that the infrared rangefinder 1 on the rotation adjustment seat 3 is adjusted to the horizontal level;

[0043] Through the push rod 14, the compressed gas enters the telescopic rod 5 through the air pipe 17, so that the telescopic rod 5 is extended under the action of the air pressure (the switch valve 16 is in the open state at this time), driving the laser receiving plate 7 to move upward;

[0044] At the same time, the micro motor 6 is configured to drive the laser receiving plate 7 to rotate and adjust the direction, and the electric push rod 8 is configured to push the movable positioning block 9 to move to the top of the measurement target body. Then, the switch valve 16 is opened to deflate. When the positioning block 9 is observed to be set above the measurement target body (more air can be deflated appropriately, because it will be set above the target body and will not continue to fall, thereby avoiding inaccuracies caused by observation problems), the infrared rangefinder 1 is convenient to work to irradiate infrared rays onto the laser receiving plate 7 for reflection induction to measure the vertical distance.

[0045] The electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that plays a control role such as a computer, and the existing public power connection technology is not repeated in the text. For example, a rechargeable battery can be set in the rotating adjustment seat 3, and a curled (capable of adapting to changes in length) cable (not shown in the figure) can be used to power each electronic component.
