Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, specifically a mobile underground space surveying device. Background Technology

[0002] Mobile underground space mapping devices are intelligent equipment that integrates multiple sensors and a mobile platform to autonomously or assistedly complete three-dimensional spatial data acquisition, modeling, and analysis in underground environments, such as tunnels, pipelines, mines, karst caves, and underground parking garages. Its core function is to generate high-precision digital models of underground space through real-time positioning and dynamic scanning, providing data support for engineering design, disaster prevention, and resource exploration.

[0003] Mobile underground space surveying equipment is mainly divided into UAV-type surveying devices, backpack-type surveying devices, vehicle-mounted surveying devices, and handheld portable surveying devices. Among them, backpack-type surveying devices mostly integrate dual lidar, panoramic camera and GNSS, and can collect 640,000 points per second when walking or cycling, and can achieve an absolute accuracy of 5 centimeters in underground parking lots.

[0004] With existing backpack-style surveying equipment, staff often place the equipment on their chest and connect it to their mobile phones to survey the surrounding environment in real time while walking. However, the equipment shakes during walking, and underground parking garages are mostly large areas, which can cause fatigue for staff and reduce work efficiency. In addition, placing the equipment on the chest also creates blind spots in terms of field of view. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a mobile underground space mapping device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile underground space mapping device, comprising an energy storage battery box and a shoulder strap, wherein a limiting frame is installed at one end of the energy storage battery box, and a shoulder strap is installed at one end of the limiting frame, and positioning plates are connected to both ends of the shoulder strap, and the positioning plates are in contact with the outer wall of the limiting frame, an electric push rod is installed on the inner wall of the limiting frame, and a limiting plate is installed on the top of the electric push rod, and a measuring component is installed on the top of the limiting plate.

[0007] By adopting the above technical solution, the equipment is carried on the back using an electric push rod and shoulder strap.

[0012] The present invention is further configured such that the other end of the damping rod is movably connected to the outer wall of the electric push rod, and the electric push rod and the telescopic rod are arranged opposite to each other.

[0013] Preferably, the damping rod improves the stability of the electric push rod during movement and also improves the stability of the measuring component during movement, reducing the shaking of the measuring component.

[0014] The present invention is further configured such that the electric push rod includes a base, a moving rod, a protrusion, and a sliding groove, and the moving rod is provided with a protrusion at one end near the shoulder strap.

[0015] Preferably, this effectively improves the stability of the moving rod during movement and reduces the possibility of the measuring component shaking.

[0016] The present invention is further provided in that the outer wall of the base is provided with a sliding groove, and a protrusion is movably fitted in the sliding groove.

[0017] Preferably, the inward and outward extension of the moving rod also effectively limits the movement of the moving rod.

[0018] The present invention is further configured such that a groove is provided at one end of the positioning plate near the electric push rod, and the groove engages with the protrusion.

[0019] Preferably, the groove design improves the stability of the electric push rod during movement, reduces the shaking of the measuring component, and improves the accuracy of the measuring component.

[0020] The present invention is further configured such that a fixing frame can be fitted onto the bottom of the positioning plate, and the fixing frame has through holes at both ends.

[0021] Preferably, reducing the shaking of the measuring component improves the accuracy of the measurement.

[0022] The present invention is further configured such that the outer wall of the fixed frame is also provided with a groove, and the part of the positioning plate sleeved inside the fixed frame is also provided with a through hole, and the two sets of through holes are arranged opposite to each other.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figures 1-5 The device includes a battery storage box 1 and a shoulder strap 3. A limiting frame 2 is installed at one end of the battery storage box 1, and a shoulder strap 3 is installed at one end of the limiting frame 2. Positioning plates 30 are connected to both ends of the shoulder strap 3, and the positioning plates 30 are fitted against the outer wall of the limiting frame 2. An electric push rod 20 is installed on the inner wall of the limiting frame 2, and a limiting plate 21 is installed on the top of the electric push rod 20. A measuring component 22 is installed on the top of the limiting plate 21. The device is carried on the back using the electric push rod 20 and the shoulder strap 3. An electric push rod 20 is installed at the bottom of the measuring component 22. The height can be adjusted according to the height of the staff. This also makes it easier for the staff to adjust the height of the measuring component 22 to perform secondary measurements on site, improving the accuracy of the equipment measurement and greatly reducing the measurement blind spot when the equipment is placed in front of the chest. Through the setting of the damping rod 23, the damping rod 23 effectively supports and limits the outer wall of the electric push rod 20, improving the stability of the electric push rod 20 during movement and reducing the shaking generated by the electric push rod 20 during movement, thereby reducing the shaking generated by the equipment during measurement.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 A telescopic rod 10 is installed on the top of the energy storage battery box 1, and the top of the telescopic rod 10 is connected to the bottom of the limiting plate 21. The telescopic rod 10 provides secondary support for the limiting plate 21, thereby improving the stability of the measuring component 22 when it is raised or lowered.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3The energy storage battery box 1, the limiting frame 2 and the positioning plate 30 are fixedly connected, and the inner wall of the limiting frame 2 is movably installed with a damping rod 23. The two ends of the limiting frame 2 are movably installed with the damping rod 23, and the damping rod 23 is movably connected with the outer wall of the base 201, which effectively improves the stability of the moving rod 202 during movement.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The other end of the damping rod 23 is movably connected to the outer wall of the electric push rod 20, and the electric push rod 20 is set opposite to the telescopic rod 10. The damping rod 23 improves the stability of the electric push rod 20 when it moves, and also improves the stability of the measuring component 22 when it moves, reducing the shaking of the measuring component 22.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The electric push rod 20 includes a base 201, a moving rod 202, a protrusion 203, and a slide groove 204. The end of the moving rod 202 near the shoulder strap 3 is provided with a protrusion 203, which effectively improves the stability of the moving rod 202 during movement and reduces the possibility of the measuring component 22 shaking.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The outer wall of the base 201 is provided with a sliding groove 204, and a protrusion 203 is movably sleeved in the sliding groove 204, which facilitates the inward and outward movement of the moving rod 202 and also effectively limits the moving rod 202.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The positioning plate 30 has a groove 301 at one end near the electric push rod 20, and the groove 301 engages with the protrusion 203. The groove 301 improves the stability of the electric push rod 20 during movement, reduces the shaking of the measuring component 22, and improves the measurement accuracy of the measuring component 22.

[0044] Second embodiment:

[0045] Please see Figure 4 The difference between Embodiment 2 and Embodiment 1 is that, while retaining Embodiment 1, a fixing frame 302 is added to the bottom of the positioning plate 30, which makes it easier to adjust the height of the positioning plate 30 and improves the comfort of wearing the device.

[0046] A fixing frame 302 is fitted at the bottom of the positioning plate 30, and through holes 303 are provided at both ends of the fixing frame 302. A through hole 303 is also provided where the positioning plate 30 contacts the through hole 303, so as to limit the height of the positioning plate 30 moving out of the fixing frame 302. The limit can be made by bolts and nuts, which improves the applicability of the equipment.

[0047] In practical operation, this utility model is as follows:

[0048] When it is necessary to measure the underground parking garage space, first activate the control button, and the staff adjusts the length of the electric push rod 20 according to their own height so that the measuring component 22 is located above the staff's head. Then, the staff puts the equipment on their back through the shoulder strap 3, and finally activates the measuring component 22 so that the measuring component 22 can start working and begin to measure the underground parking garage environment.

[0049] Furthermore, when the height of the measuring component 22 needs to be adjusted due to the high space height, the electric push rod 20 is moved upward by the control button, so that the protrusion 203 moves in the groove 301. Secondly, the damping rods 23 are movably installed at both ends of the limiting frame 2, and the damping rods 23 are movably connected to the outer wall of the base 201, which effectively improves the stability of the moving rod 202 during movement and reduces the possibility of the measuring component 22 shaking.

[0050] Furthermore, when staff feel that the positioning plate 30 is too short and does not fit their back properly, the positioning plate 30 can be moved upwards so that it moves within the fixed frame 302. Then, the position of the positioning plate 30 can be limited by bolts and nuts passing through the through hole 303, which facilitates the control of the height of the positioning plate 30 and improves the comfort of staff wearing the equipment.
