Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping engineering technology, and more specifically, to a detection device for surveying and mapping engineering. Background Technology

[0002] In surveying engineering, 3D laser scanners are used to accurately locate and describe the shape of geological objects in three dimensions, obtaining accurate coordinates, distances, angles, and other information. This provides reliable basic data for geological analysis. They offer advantages such as large scanning area, rapid acquisition of three-dimensional terrain information, and comprehensive scanning and data collection of the entire geological area. Traditional 3D laser scanners are mounted on tripods. When the tripod is folded open, the scanner's mounting height cannot be adjusted, requiring repositioning of the tripod. Furthermore, the stability of the tripod decreases when it is narrowed. When adjusting the surveying location over short distances, the 3D laser scanner must be removed and the tripod re-supported; it cannot be directly moved, otherwise, the scanner risks falling. Utility Model Content

[0003] The purpose of this invention is to provide a detection device for surveying engineering, which enables the lifting and installation of a 3D laser scanner over a large range, and allows for safe short-distance transfer without removing the 3D laser scanner.

[0004] This utility model discloses a surveying and mapping engineering testing device, comprising: a three-dimensional laser scanner, a cross column, and a leveling base for leveling the three-dimensional laser scanner. The bottom end of the leveling base is detachably connected to a lifting rod. The cross column includes a guide cylinder and a horizontal column. The lifting rod is slidably connected to the guide cylinder. A locking rod is installed on the guide cylinder for locking the lifting rod. Two folding leg assemblies are rotatably installed at both ends of the horizontal column.

[0005] Furthermore, the folding leg assembly includes a straight leg and a Z-shaped leg. The upper end of both the straight leg and the Z-shaped leg is fixedly provided with a rotating sleeve connected to the cross column. The rotating sleeve is locked to the cross column by a first screw. The bottom end of both the straight leg and the Z-shaped leg is equipped with a moving mechanism.

[0006] Furthermore, the leveling base is rotatably mounted with two protective covers, each containing foam cotton with a groove matching the 3D laser scanner. When the protective covers are closed, the 3D laser scanner is enclosed within the groove.

[0007] Furthermore, the moving mechanism includes a U-shaped screw block, and a U-shaped screw block is fixedly provided at the bottom end of both the straight leg and the Z-shaped leg. A second screw is threadedly installed on the U-shaped screw block, and a self-locking universal wheel is rotatably connected to the bottom end of the second screw.

[0008] By adopting the above technical solution, the 3D laser scanner is mounted on the upper end of the lifting rod via a leveling base. The lifting rod is slidably connected to the cross column. By sliding the lifting rod along the cross column, the installation height of the 3D laser scanner can be freely adjusted, thereby adjusting the laser scanning range and coverage area of ​​the 3D laser scanner. Two folding leg assemblies are installed on the cross column. Each folding leg assembly consists of a straight leg and a Z-shaped leg. By opening the straight leg and the Z-shaped leg, the two straight legs and the two Z-shaped legs form a four-leg structure, which can be stably placed on the ground. Each straight leg and the Z-shaped leg is equipped with an adjustable self-locking universal wheel at its bottom. Thus, when it is necessary to move the entire structure, it can be pushed and moved using the four self-locking universal wheels. During movement, two protective covers can be placed on the outside of the 3D laser scanner, and foam cotton can be used to provide physical protection for the 3D laser scanner, avoiding damage to the 3D laser scanner caused by the whole structure falling.

[0009] Optionally, the leveling base is provided with three adjusting columns, and the upper end of the adjusting columns is connected to a ball joint 3D laser scanner. Flanges are fixed at both ends of the lifting rod, and the flanges are fixedly connected to the leveling base by bolts.

[0010] By adopting the above technical solution, after the four support legs structure formed by the two straight legs and the two Z-shaped legs is placed on the ground, the 3D laser scanner itself is equipped with a level bubble structure. By adjusting the three adjustment columns on the leveling base, the 3D laser scanner can be leveled. The leveling base can be fixed to the flange by multiple bolts and threads, and then the installation height of the 3D laser scanner can be adjusted by sliding the lifting rod along the cross column.

[0011] Optionally, both the straight leg and the Z-shaped leg can be detachably fitted with wear-resistant rubber sleeves at their bottom ends. The straight leg has a slot, and the Z-shaped leg has an L-shaped elastic block fixedly attached to it, which is elastically engaged with the slot.

[0012] By adopting the above technical solution, the bottom of the wear-resistant rubber sleeve achieves wear resistance. When folded and stored, the Z-shaped leg structure is attached to the surface of the straight leg, and the L-shaped elastic block is elastically engaged in the slot.

[0013] Optionally, each of the protective covers is fixedly provided with a rotating block and two U-shaped blocks, and the leveling base is fixedly provided with two rotating seats. The rotating seats are rotatably connected to the rotating block of one of the protective covers through shafts. The two protective covers are rotated and closed, and screws are threaded between the U-shaped blocks.

[0014] By adopting the above technical solution, when the 3D laser scanner is not in use, the two protective covers can be closed by rotating them, and the U-shaped blocks on the protective covers can be fixedly connected by screws. In this way, the foam cotton inside the two protective covers can protect the 3D laser scanner during processing.

[0015] One or more technical solutions provided in this utility model have at least the following technical effects or advantages:

[0016] 1. This 3D laser scanner is easy to install and remove from the lifting rod. Compared with the traditional tripod, the installation height of the 3D laser scanner can be freely adjusted by sliding the lifting rod along the guide tube, thereby adjusting the laser scanning range and coverage area of ​​the 3D laser scanner, improving measurement accuracy and data reliability.

The bottom end of the leveling base 11 is detachably connected to a lifting rod 3, and the lifting rod 3 is slidably connected to a cross post 2. Two folding leg assemblies 4 are rotatably mounted on the cross post 2.

[0025] Two protective covers 6 are rotatably mounted on the leveling base 11. Foam cotton is provided inside the protective cover 6, and the foam cotton is provided with grooves 61 that match the 3D laser scanner 1.

[0026] The folding leg assembly 4 includes a straight leg 41 and a Z-shaped leg 42. The upper ends of both the straight leg 41 and the Z-shaped leg 42 are fixedly provided with rotating sleeves 43, and the lower ends of both the straight leg 41 and the Z-shaped leg 42 are provided with moving mechanisms 5.

[0027] The moving mechanism 5 includes a U-shaped screw block 51. A U-shaped screw block 51 is fixed to the bottom end of each of the straight legs 41 and Z-shaped legs 42. A second screw 52 is threaded onto the U-shaped screw block 51. A self-locking universal wheel 53 is rotatably connected to the bottom end of the second screw 52. The 3D laser scanner 1 is mounted on the upper end of the lifting rod 3 via a leveling base 11. The lifting rod 3 is slidably connected to the cross post 2. By sliding the lifting rod 3 along the cross post 2, the installation height of the 3D laser scanner 1 can be freely adjusted, thereby adjusting the laser scanning range and coverage area of ​​the 3D laser scanner 1. Two folding leg assemblies 4 are installed on the cross post 2. Each folding leg assembly 4 consists of a straight leg 41 and a Z-shaped leg 42, which can be connected by... The straight legs 41 and Z-shaped legs 42 are rotated and opened in a triangular structure, forming a four-leg structure that can be stably placed on the ground. Each of the straight legs 41 and Z-shaped legs 42 is equipped with an adjustable self-locking caster 53 at its bottom. When the overall structure needs to be moved, it can be pushed and moved using the four self-locking caster 53. It can also be folded and stored in the folding leg assembly 4 for portability. It is flexible in use. During the movement, two protective covers 6 can be used to cover the outside of the 3D laser scanner 1, and foam cotton can be used to provide physical protection for the 3D laser scanner 1 to prevent damage to the 3D laser scanner 1 from falling.

[0028] Reference Figure 2 and Figure 3The leveling base 11 is equipped with three adjusting columns, and the upper end of the adjusting columns is connected to the 3D laser scanner 1 via a ball joint. The lifting rod 3 has a flange 31 and an anti-slip block 32 fixed at both ends. The flange 31 is fixed to the leveling base 11 by bolts. The two straight legs 41 and the two Z-shaped legs 42 form a four-leg support structure. After being placed on the ground, the 3D laser scanner 1 is equipped with a level bubble structure. The 3D laser scanner 1 can be leveled by adjusting the three adjusting columns on the leveling base 11. The leveling base 11 can be fixed to the flange 31 by multiple bolt threads. Then, the installation height of the 3D laser scanner 1 can be adjusted by sliding the lifting rod 3 along the cross column 2.

[0029] Reference Figure 1 and Figure 2 The cross post 2 includes a guide cylinder 21 and a horizontal column 23, which are integrally fixedly connected. A damping sleeve 211 is installed inside the guide cylinder 21. The lifting rod 3 slides along the damping sleeve 211 in a damped manner. A locking rod 22 is threaded on the guide cylinder 21 and abuts against the outer surface of the lifting rod 3. The cross post 2 is composed of the guide cylinder 21 and the horizontal column 23 fixedly connected. Two folding leg assemblies 4 are symmetrically arranged along the axis of the guide cylinder 21. Each folding leg assembly 4 includes a straight leg 41 and a Z-shaped leg 42. After the lifting rod 3 slides along the damping sleeve 211 in a damped manner, the locking rod 22 is tightened to limit and fix the lifting rod 3, thereby limiting the installation of the three-dimensional laser scanner 1 to the required height position.

[0030] Reference Figure 1 and Figure 2 The rotating sleeves 43 fixed at the upper ends of the straight leg 41 and the Z-shaped leg 42 are rotatably connected to the horizontal column 23. The end of the horizontal column 23 is threaded with a first screw 24. Tightening the first screw 24 will press against the rotating sleeves 43 fixed at the upper ends of the straight leg 41 and the Z-shaped leg 42. The straight leg 41 and the Z-shaped leg 42 can rotate along the horizontal column 23 through the rotating sleeves 43 connected at the upper ends. Then, by locking the first screw 24, the two rotating sleeves 43 can be pressed against each other, thereby positioning the included angle between the straight leg 41 and the Z-shaped leg 42.

[0031] Reference Figure 2 and Figure 3 Both the straight leg 41 and the Z-shaped leg 42 have strip-shaped through grooves 44. The bottom ends of both the straight leg 41 and the Z-shaped leg 42 can be detachably fitted with wear-resistant rubber sleeves 45. The straight leg 41 has a slot 411, and the Z-shaped leg 42 has an L-shaped elastic block 421 fixedly attached to it. The L-shaped elastic block 421 is elastically engaged with the slot 411. The straight leg 41 and the Z-shaped leg 42 can be easily rotated by the strip-shaped through grooves 44. The wear-resistant rubber sleeve 45 is provided at the bottom to achieve a wear-resistant effect. When folded for storage, part of the Z-shaped leg 42 is attached to the surface of the straight leg 41, and the L-shaped elastic block 421 is elastically engaged with the slot 411.

[0032] Reference Figure 2 and Figure 3 Each protective cover 6 is fixed with a rotating block 65 and two U-shaped blocks 62. The upper end of the guide cylinder 21 is fixed with two rotating seats 64. The rotating seats 64 are rotatably connected to the rotating block 65 of one of the protective covers 6 via shafts. The two protective covers 6 are rotated to close, and screws 63 are threaded between the U-shaped blocks 62. When the 3D laser scanner 1 is not in use, the two protective covers 6 are closed by rotating, and the U-shaped blocks 62 on the protective covers 6 are threadedly fixed by the screws 63. Thus, the foam cotton inside the two protective covers 6 can protect the 3D laser scanner 1 during processing.

[0033] During installation, the leveling base 11 connected to the bottom of the 3D laser scanner 1 is fixed to the flange 31 at the upper end of the lifting rod 3 using multiple bolts. In use, two folding leg assemblies 4 are symmetrically installed on the cross-shaped column 2, which is fixedly connected by the guide cylinder 21 and the cross column 23. Each folding leg assembly 4 consists of a straight leg 41 and a Z-shaped leg 42. The straight leg 41 and Z-shaped leg 42 can be rotated open using a triangular structure, forming four support legs that can stably place the device on the ground. The foldable storage function of the straight leg 41 and Z-shaped leg 42 makes it easy to carry. Furthermore, each of the straight leg 41 and Z-shaped leg 42 has an adjustable self-locking universal joint at its bottom. The four self-locking casters 53 allow for easy movement of the entire structure when needed. After the straight legs 41 and Z-shaped legs 42 are rotated open and stably placed on the ground, the lifting rod 3 slides along the damping sleeve 211 inside the guide cylinder 21 and locks the locking rod 22, allowing for free adjustment of the installation height of the 3D laser scanner 1. This adjusts the laser scanning range and coverage area of ​​the 3D laser scanner 1, making it flexible to use. When the 3D laser scanner 1 is not in use, two protective covers 6 can be placed on the outside of the 3D laser scanner 1 and the leveling base 11, using foam cotton to provide physical protection for the 3D laser scanner 1 and prevent damage caused by the entire structure falling.
