[0037] The specific embodiments of the application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the application.

[0038] The application will be described in detail below with reference to the drawings and exemplary embodiments.

[0039] Embodiment One

[0040] Please refer to Figure 1 and Figure 4The embodiment provides a height measuring device suitable for engineering machinery, which is referred to as a height measuring device hereinafter. The height measuring device can be used for measuring the height of engineering machinery in different postures, and the engineering machinery is taken as an excavator for example in the embodiment.

[0041] The height measuring device comprises a base 100, a lifting assembly 200, a positioning assembly 300 and a laser measuring device 400. The base 100 is movably arranged on a foundation, and the lifting assembly 200, the positioning assembly 300 and the laser measuring device 400 are all arranged on the base 100.

[0042] The lifting assembly 200 can be lifted in the vertical direction to meet the measurement requirement of different heights. The positioning assembly 300 comprises a measuring plate 310 and a positioning ruler 320. The measuring plate 310 is arranged on the lifting assembly 200, and the positioning ruler 320 is arranged on the measuring plate 310 and extends away from the measuring plate 310. The positioning ruler 320 is parallel to the horizontal plane and is used for contacting the to-be-measured point on the excavator. The laser measuring device 400 is arranged on the bottom of the lifting assembly 200 or the measuring plate 310.

[0043] It can be understood that the excavator itself has a certain width. When the height is measured, the height measuring device can only be arranged on one side of the excavation, and the to-be-measured point of the excavator can be located on the vertical plane in the middle. Therefore, the positioning ruler 320 is extended to contact the to-be-measured point, so that the measuring plate 310 is flush with the to-be-measured point in the horizontal direction, thereby ensuring that the subsequent measurement is more accurate.

[0044] Compared with the prior art, the height measuring device provided by the embodiment can be used for measuring the maximum height of the excavator in the transportation posture when the height of the excavator is measured. The specific steps are as follows: firstly, the excavator is ensured to be in the transportation posture, then the whole height measuring device is moved to the position below the to-be-measured point, the height of the measuring plate 310 is adjusted through the lifting assembly 200, and when the positioning ruler 320 contacts the to-be-measured point on the excavator, the lifting of the lifting assembly 200 is stopped, so that the lifting assembly 200 is kept, and then the height of the measuring plate 310 to the base 100 is measured through the laser measuring device 400, so that the height information of the to-be-measured point on the excavator is obtained.

[0045] In this way, the height measuring device provided by the embodiment does not need manual climbing, is high in measurement efficiency and is safer and more reliable. The whole measurement process can be completed by one person, manpower is saved, and labor intensity is reduced. The measurement error is reduced through repeated measurement, and the measurement precision is improved.

[0046] In order to more clearly describe the technical scheme of the present application, the height measuring device provided by the embodiment is described below, and the specific steps are as follows:

[0047] The laser measuring device 400 can be a laser range finder or a fiber-optic range finder.

[0048] The base 100 is a flat plate structure, and the lifting assembly 200 is arranged on the base 100.

[0049] The lifting assembly 200 includes a base 210 and telescopic rods 220. The base 210 is fixedly connected to the base 100 by bolts. The telescopic rods 220 are arranged on the base 210, and the measuring plate 310 is arranged on the top of the telescopic rods 220. In this way, the measuring plate 310 can be lifted in the vertical direction by the telescopic driving of the telescopic rods 220, so as to adapt to the measurement of different heights.

[0050] Specifically, the telescopic rods 220 include multiple telescopic sections. The first section in the multiple telescopic sections is defined as the first telescopic section, the telescopic section at the last position is defined as the last telescopic section, and the telescopic sections between the first telescopic section and the last telescopic section are intermediate telescopic sections. The measuring plate 310 is arranged on the last telescopic section.

[0051] It should be noted that in the telescopic rods 220, adjacent telescopic sections are connected by a specific connection mode, so that the entire telescopic rods 220 can remain stable when being stretched or contracted. For example, the connection modes include threaded connection, hook-and-tongue connection, gear connection, etc.

[0052] When the length of the telescopic rods 220 needs to be adjusted, the relative positions of the telescopic rods 220 in the length direction can be changed. If threaded connection is adopted, the threads can be rotated to gradually separate or approach the two telescopic rods 220, so as to change the length of the entire telescopic rods 220. If hook-and-tongue connection is adopted, the tenons between the rod members can be taken out or inserted, so as to change the length of the entire rod members. In addition, the telescopic rods 220 are usually equipped with a locking mechanism for fixing the position of the telescopic rods 220 when needed. This can prevent the telescopic rods 220 from accidentally stretching or contracting during use, and ensure the stability and safety thereof.

[0053] In some embodiments, the base 100 is further provided with a level detector 500.

[0054] In some other embodiments, the level detector 500 can also be arranged on the lifting assembly 200.

[0055] In this way, the level detector 500 ensures that the entire height measuring device remains in a horizontal state during measurement, thereby improving the accuracy of measurement. Optionally, the level detector 500 can be a liquid level detector or an electronic level detector.

[0056] In the embodiment, the measuring plate 310 is made of a high-hardness nylon plate with low density. The positioning ruler 320 is made of a high-hardness alloy and is detachable, and is used for translational positioning of the required measuring point.

[0057] In some embodiments, the base 100 is provided with a roller assembly at the bottom, so as to facilitate adjustment of the position of the height measuring device and improve the convenience of operation.

[0058] Optionally, the roller assembly can be provided in multiple numbers and can be a universal wheel.

[0059] Compared with the prior art, the height measuring device provided in the embodiment has the following advantages:

[0060] 1. In the embodiment, the problem that the product measuring point cannot be directly measured by using a traditional tool is solved by laser ranging.

[0061] 2. In the embodiment, the reference positioning is performed on the surface of the base 100, and the surface is used as the measuring reference, so that the measuring accuracy is high.

[0062] 3. In the embodiment, the structure is simple, the operation is simple, and the operation can be performed, so that the measuring efficiency is improved.

[0063] Embodiment Two

[0064] Please refer to Figure 2 and Figure 4 , the embodiment provides a height measuring device. The height measuring device provided in the embodiment is an improvement on the basis of the technology of the above-mentioned embodiment one, and compared with the embodiment one, the difference lies in that:

[0065] In the embodiment, considering that the positioning ruler 320 needs a certain length, the positioning ruler 320 usually needs to be installed first before measurement is started. If the horizontal distance between the height measuring device and the excavator is not well grasped, the positioning ruler 320 is easy to collide with the excavator and cause interference when the height of the lifting assembly 200 is adjusted, so that the positioning ruler 320 is damaged and the measuring accuracy is affected.

[0066] In order to solve the above-mentioned problem, in the embodiment, the positioning ruler 320 is rotationally connected with the measuring plate 310, and the rotation axis of the positioning ruler 320 is parallel to the vertical direction. For example, a pin shaft is used to realize the rotational connection. In this way, when the height is measured, the positioning ruler 320 can be rotated to a preset position in advance to ensure that the positioning ruler 320 deviates from the excavator, the height of the lifting assembly 200 is adjusted, the measuring plate 310 reaches the preset height, the positioning ruler 320 is rotated again, so that the positioning ruler 320 is located above the measuring point, and then the lifting assembly 200 is controlled to be lowered to make the positioning ruler 320 contact the measuring point. Thus, the interference and collision of the positioning ruler 320 with the excavator are effectively avoided.

[0067] Of course in some embodiments, the positioning ruler 320 can be fixedly installed on the measuring plate 310, for example, fixedly installed by bolts. Among them, the telescopic rod 220 is rotationally matched with the base 210, and the rotation axis of the telescopic rod 220 is parallel to the vertical direction. In this way, when the height is measured, the positioning ruler 320 can be rotated to a preset position by rotating the telescopic rod 220 in advance, so as to ensure that the positioning ruler 320 deviates from the excavator, and then the height of the lifting assembly 200 is adjusted, and when the measuring plate 310 reaches the preset height, the positioning ruler 320 is rotated to the upper side of the measured point by rotating the telescopic rod 220, and then the lifting assembly 200 is controlled to descend, so that the positioning ruler 320 is in contact with the measured point. Thus, the positioning ruler 320 and the excavator are effectively avoided from interfering and colliding.

[0071] Specifically, the base 100 is provided with a sliding rail 110, and the base 210 is arranged on the sliding rail 110 through a sliding block. In this way, the sliding rail 110 can be adjusted to translate by manually pushing.

[0072] In some embodiments, the height measuring device further comprises a linear driving mechanism arranged on the base 100 and used for driving the base 210 to slide along the sliding rail 110.

[0073] Optionally, the linear driving mechanism can be an electric cylinder, an electric push rod, a linear motor or a motor lead screw. It should be understood that the above-mentioned is only an example and does not limit the protection scope of the present application.

[0074] In some embodiments, the height measuring device further comprises a leveling assembly 120 arranged on the base 100 and used for adjusting the level of the base 100. For example, leveling bolts or leveling legs are used for leveling.

[0075] In some embodiments, the height measuring device further comprises a wireless communication assembly electrically connected with the laser measuring device 400 and used for receiving or sending wireless signals.
