Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, and more specifically to a device for measuring three-dimensional information of underground space. Background Art

[0002] In some areas, there are natural underground caves or cavities left by artificial mining. Such underground spaces will pose a serious threat to the surface buildings, roads, bridges and other engineering construction above them. Therefore, it is necessary to measure the underground space during geological exploration to provide a basis for subsequent engineering construction. When measuring underground space, a 3D laser measuring instrument is often used for measurement. At present, when installing a 3D laser measuring instrument, the 3D laser measuring instrument is usually placed in the borehole using the cable that comes with the 3D laser measuring instrument, and then moved downward into the underground space to perform multiple measurements at different heights.

[0003] A Chinese patent discloses a device for measuring three-dimensional information of underground space with patent number CN202220035564.9. The device for measuring three-dimensional information of underground space uses two suspension ropes to connect a fixed plate, and installs a scanning unit under the fixed plate. Compared with the conventional single-cable installation of the scanning unit, it is more stable, and the scanning unit is not prone to shaking and rotating, which improves the measurement efficiency. However, there are still certain problems. The stabilizing plate of the device is a whole piece and can only be used for drilling holes that are compatible with it. If the drilling space is too large or too small, the stability of the measurement and control unit cannot be ensured, and a whole stabilizing plate cannot adjust its own width, thereby reducing the overall adaptability. Utility Model Content

[0004] The purpose of the utility model is to provide a device for measuring three-dimensional information of underground space to solve the problems raised in the above background technology:

[0005] Some existing devices for measuring three-dimensional information of underground space have a whole stabilizing plate, which can only be used in boreholes that match them. If the borehole space is too large or too small, the stability of the measurement and control unit cannot be ensured, and a whole stabilizing plate cannot adjust its own width, thereby reducing the overall adaptability.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The cam is an angular channel formed between a pair of camshafts and a pair of camshafts, and the camshafts are connected to a pair of camshafts which are linked together by a threaded cantilever cam.

[0008] Preferably, there are three grooves in total, and the three grooves are symmetrically distributed. Correspondingly, there are three groups of other accessories arranged in the grooves.

[0009] Preferably, the outer wall of the rack fits with the inner wall of the groove, the rack is slidably connected to the stabilizing plate, and the rack is limited by the groove.

[0010] Preferably, the first rotating rod and the second rotating rod have the same size, and the same size of the first rotating rod and the second rotating rod enables the support rod and the fixing plate to always remain parallel, thereby ensuring the stability of the measurement and control unit when it descends.

[0011] Preferably, the support rod is an H-shaped structure, and the H-shaped structure enables the first rotating rod and the second rotating rod to be installed on the support rod, making the overall structure more compact and regular.

[0012] Preferably, the gear is integrally formed with the first rotating rod. The gear is formed by opening a tooth groove on the outside of the first rotating rod near one end of the stabilizing plate. The gear is meshed with the rack. When the rack moves up and down, the first rotating rod is driven to swing up and down through the gear, and the position of the support rod is adjusted in cooperation with the second rotating rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The user can directly screw the hand screw, and the hand screw will drive three racks in different positions to move up or down at the same time through the adjustment plate. The rack then drives the first rotating rod to swing up and down through the gear, so that the first rotating rod cooperates with the second rotating rod to drive the support rod to expand outward or contract inward until the roller on the support rod can contact the inner wall of the drilled hole, thereby achieving the purpose of adapting to drilling holes of different diameters.

[0020] 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.

A groove 6 is provided inside the stabilizing plate 5. A first rotating rod 7 is provided inside the groove 6. The first rotating rod 7 is rotatably connected to the stabilizing plate 5. An end of the first rotating rod 7 away from the stabilizing plate 5 is rotatably connected to a support rod 8. A roller 9 is fixedly connected to the outside of the support rod 8. A second rotating rod 10 is rotatably connected to the inside of the support rod 8. The corresponding two sides of the second rotating rod 10 are rotatably connected to fixed plates 11. The support rod 8 and the fixed plate 11 always remain parallel to each other, the fixed plate 11 is fixedly connected to the stabilizing plate 5, the top of the stabilizing plate 5 is rotatably connected with a hand screw 12, the external thread of the hand screw 12 is connected with an adjusting plate 13, the external part of the adjusting plate 13 is fixedly connected with a rack 14, the external part of the first rotating rod 7 is fixedly connected with a gear 15, the gear 15 is meshed with the rack 14, the up and down movement of the rack 14 will drive the gear 15 to rotate, and the gear 15 will drive the first rotating rod 7 to swing up and down to cooperate with the position of the second rotating rod 10 to support the rod 8.

[0022] Furthermore, there are three grooves 6 in total, and the three grooves 6 are symmetrically distributed. Correspondingly, there are three groups of other accessories arranged in the grooves 6, which can ensure the stability of the measurement and control unit 4 when it descends from three different positions.

[0023] Furthermore, the outer wall of the rack 14 fits with the inner wall of the groove 6, the rack 14 is slidably connected to the stabilizing plate 5, and the rack 14 is limited by the groove 6. When the user screws the hand screw 12, the rack 14 can be driven to move up and down through the adjustment plate 13.

[0024] Furthermore, the first rotating rod 7 and the second rotating rod 10 have the same size. The same size as the second rotating rod 10 allows the support rod 8 and the fixed plate 11 to always remain parallel, ensuring that the roller 9 on the support rod 8 can contact the inner wall of the drilled hole, thereby ensuring the stability of the measurement and control unit 4 when it descends.

[0025] Furthermore, the support rod 8 is an H-shaped structure, and the H-shaped structure enables the first rotating rod 7 and the second rotating rod 10 to be installed on the support rod 8, making the overall structure more compact and regular.
