Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping devices, and in particular to a laser surveying and mapping device based on municipal engineering surveying and mapping. Background Art

[0002] During the construction of municipal engineering projects, surveying and mapping plays an important role in monitoring and controlling. Through regular or real-time surveying and mapping, deviations and problems in the project can be discovered in a timely manner, such as foundation settlement, wall tilt, uneven road surface, etc., so that corresponding rectification measures can be taken to ensure that the project quality meets the design requirements.

[0003] At present, the prior art usually uses laser surveying and mapping devices for measurement. The laser surveying and mapping devices usually include the following basic components: laser transmitter, receiver, control system, power supply system and necessary support structure. When in use, the operator will set up the device and calibrate it, then start the laser transmitter, the laser beam will irradiate the target point, and the reflected laser will be captured by the receiver and converted into an electrical signal. The control system processes these signals and calculates the distance and position information of the target. This information can be used to generate topographic maps, building layout maps, etc. However, in actual use, many devices are easily disturbed by sunlight, resulting in data deviations. When exposed to sunlight, the sensor of the laser rangefinder is easily overheated, thereby affecting its stability and service life.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The embodiment of the present application provides a laser surveying and mapping device based on municipal engineering surveying and mapping, which solves the problem that in the actual use of the prior art, many devices are easily disturbed by sunlight, resulting in data deviations, and the laser rangefinder sensor is easily overheated when exposed to sunlight, thereby affecting its stability and service life. At the same time, the device is not protected and is easily damaged during use or storage, thereby reducing its service life.

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] Embodiment 1:

[0049] The embodiment of the present invention discloses a laser surveying and mapping device based on municipal engineering surveying and mapping. Figure 1-9 As shown, including:

[0050] A protection box 1, used for protecting the device;

[0051] A bottom bracket 2 is disposed below the protective box 1 and provides support for the device;

[0052] The electric push rod 3 is arranged on the protection box 1;

[0053] The surveying and mapping device body 4 is arranged at the output end of the electric push rod 3 and is located inside the protective box 1. The electric push rod 3 is used to control the lifting and lowering of the surveying and mapping device body 4;

[0054] A top cover plate 5 is disposed above the surveying and mapping device body 4 and is used to protect the top of the surveying and mapping device body 4;

[0055] A support seat 6 is disposed below the top cover plate 5 and supports the top cover plate 5. A shielding adjustment mechanism 7 for controlling the displacement of the top cover plate 5 is provided on the support seat 6;

[0056] The bearing seat 9 is arranged at the bottom of the support seat 6 and above the surveying and mapping box 42. The bearing seat 9 is provided with an angle adjustment mechanism 8 for controlling the rotation adjustment of the support seat 6.

[0057] When the device needs to be surveyed at a municipal engineering surveying site, the bottom bracket 2 is used to support the entire device so that the device support is horizontal. At this time, the electric push rod 3 drives the surveying device body 4 to extend from the inside of the protective box 1, and then laser scanning surveying is performed. The scanning operation at multiple positions is used to form a preliminary scanning model, and then the volume and structural properties of the model are determined;

[0058] During the process of the electric push rod 3 driving the surveying and mapping device body 4 to rise and fall, the surveying and mapping device body 4 will simultaneously drive the top cover plate 5 to move. The top cover plate 5 can provide protection for the top of the surveying and mapping device body 4 on the one hand, and at the same time, the surveying and mapping device body 4 can also shield the sunlight to avoid the sunlight affecting the surveying and mapping device body 4 and causing interference, resulting in inaccurate model data generation. At the same time, through the design of the shielding adjustment mechanism 7 and the angle adjustment mechanism 8, it is convenient to adjust the position and angle of the top cover plate 5 to ensure that the top cover plate 5 has a good sunlight shielding effect on the surveying and mapping device body 4, and to place the laser surveying and mapping head 43 in a position where the sun directly shines on the surveying and mapping device body 4.

[0067] The device is further designed with an angle adjustment mechanism 8, so that the support seat 6 is conveniently controlled to rotate above the bearing seat 9, thereby controlling the rotation of the top cover plate 5, thereby adjusting the angle of shielding the sun, thereby ensuring that the top cover plate 5 has a good sun shielding effect on the main body 4 of the mapping device, and improving the imaging stability;

[0068] When adjusting the angle position of the top cover plate 5, the worm 82 can be directly rotated, so that the worm 82 drives the worm wheel 81 to rotate, the worm wheel 81 drives the adjustment shaft 62 to rotate, the adjustment shaft 62 drives the support seat 6 to rotate, and the support seat 6 drives the top cover plate 5 to rotate, thereby making it easy to adjust the angle of the top cover plate 5, so as to shield the external ambient light interference factors to the greatest extent;

[0069] The angle adjustment mechanism 8 further includes a second motor 83 disposed on the side of the bearing seat 9 . A first bevel gear 84 is disposed at the output end of the second motor 83 . A second bevel gear 85 is disposed on the worm 82 . The second bevel gear 85 meshes with the first bevel gear 84 .

[0070] The device facilitates the rotation adjustment operation of the worm 82 through the design of the second motor 83, the second bevel gear 85 and the first bevel gear 84. When the worm 82 needs to be rotated, the first bevel gear 84 can be directly driven to rotate by the second motor 83, the first bevel gear 84 drives the second bevel gear 85 to rotate, and the second bevel gear 85 drives the worm 82 to rotate.

[0071] The surveying and mapping device body 4 includes:

When the position of the top cover plate 5 is adjusted, the top cover plate 5 drives the slider 51 to slide along the guide rod 61.
