Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine shaft scanning acceptance, in particular to a device for scanning and measuring high-depth shafts to prevent equipment from rotating and being damaged. Background Art
[0002] When underground mines are built, they need to be inspected and accepted. During use, the shaft may collapse, collapse, or become blocked. It is necessary to lower a 3D scanner to scan and measure the shaft, generate a 3D model for data analysis, accurately grasp the situation inside the shaft, and find the accident point. The shaft is often flooded with water, which can damage the instrument. There may also be floating stones falling from the shaft wall that can damage the instrument. When a scanner is lowered with a thin rope, the twisting force of the rope is released, causing the scanner to rotate at high speed, causing the scanner to shake and collide with the shaft wall, making it impossible to complete the scanning and modeling. It is urgent to solve the above problems to achieve the goal of safe and accurate scanning and measurement.
[0003] The biggest problem that plagues 3D scanners in measuring wells is shaking and rotation. Using a rope to lower the scanner will cause high-speed rotation, shaking and hitting the wall, which can easily lead to equipment accidents. During the lowering process, the high-speed rotation will cause the lens to turn instantly when scanning the well wall point cloud, which cannot meet the solution requirement of scanning 300,000 point clouds per second, resulting in unformed scanning results.
[0004] Therefore, in view of the above problems, a device for scanning and measuring high-depth shafts to prevent equipment rotation and damage is proposed, so as to solve the problem of high-speed rotation and shaking of the instrument and collision with the wall during the lowering process. Utility Model Content
[0005] The utility model aims to solve the above problems, thereby providing a device for scanning and measuring high-depth shafts to prevent equipment from rotating and being damaged.
[0006] The utility model solves the above problems and adopts the following technical solutions:
[0007] A device for scanning and measuring a high-depth shaft to prevent equipment from rotating and being damaged comprises a horizontal plate, a connecting portion for connecting with a rope is arranged in the middle of the top surface of the horizontal plate, an anti-collision cover and a scanner fixing frame are arranged in the middle of the bottom surface of the horizontal plate, and the scanner fixing frame is located inside the anti-collision cover;
[0008] The connecting part is composed of a first bearing, a second bearing, a rotating rod, a sleeve and a top cap. An external thread structure is opened at the top of the sleeve, and a top cap is screwed on it. The middle part of the top cap is connected to the rope. The first bearing is located in the sleeve, and the outer ring of the first bearing is fixed to the inner wall of the sleeve. The second bearing is located above the horizontal plate, and the outer ring of the second bearing is fixed to the horizontal plate. The rotating rod is located between the first bearing and the second bearing, and the two ends are respectively fixed to the inner rings of the first bearing and the second bearing.
[0009] The utility model adopting the above technical solution has the following prominent features compared with the prior art:
[0010] Through the arrangement of the connecting part, the utility model can effectively overcome the problem of the high-speed rotation of the scanner. The first bearing and the second bearing are used in cooperation to achieve self-rotation unloading. Through the rotation of the bearing, the scanner below can be stabilized without rotation, ensuring the normal scanning operation of the scanner. At the same time, the scanner is installed inside the anti-collision cover through the scanner fixing frame, which can effectively prevent the possibility of damage caused by hitting the wall during the lowering process of the scanner.
[0011] Preferably, a further technical solution of the utility model is:
[0012] The anti-collision cover is composed of several arc-shaped steel wire skeletons. Both ends of each steel wire skeleton are flat and provided with through holes, and are fixed into a lantern shape through bolts. The bolts located above are fixed to the horizontal plate. The scanner fixing frame is located inside the anti-collision cover and is fixed to the bolts connected to the horizontal plate. The anti-collision cover as a whole is in the shape of a lantern, reducing the influence on the scanner when scanning the point cloud of the shaft wall.
[0013] The distance between two adjacent steel wire skeletons is less than the width of the scanner, preventing accidents such as accidental detachment of the scanner and falling into the well.
[0014] The horizontal plate is provided with two layers up and down and is fixedly connected by bolts. An anti-smashing cover is arranged between the two horizontal plates. The diameter of the anti-smashing cover is much larger than the size of the scanner itself, ensuring that the instrument will not be damaged when floating stones fall. The instrument is located below the anti-smashing cover, which can protect the instrument from being wet by dripping water.
[0015] The centers of gravity of the connecting part, the horizontal plate, the anti-smashing cover, the anti-collision cover and the scanner fixing frame are all on the same vertical line, ensuring that the center of gravity of the whole device is vertically downward and will not tilt. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a schematic diagram of the main structure of an embodiment of the utility model;
[0017] In the figure, the markings are: horizontal plate 1, second bearing 2, first bearing 3, rotating rod 4, sleeve 5, anti-collision cover 6, scanner fixing frame 7, anti-smashing cover 8. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following further illustrates the utility model with reference to embodiments. The purpose is only to better understand the content of the utility model. Therefore, the examples given do not limit the protection scope of the utility model.
[0019] See Figure 1, a device for scanning and measuring deep vertical shafts to prevent equipment rotation and damage, including a horizontal plate 1. In the middle of the top surface of the horizontal plate 1, there is a connecting part for connecting with a rope. In the middle of the bottom surface of the horizontal plate 1, there is an anti-collision cover 6 and a scanner fixing frame 7. The scanner fixing frame 7 is located inside the anti-collision cover 6;
[0020] The connecting part consists of a first bearing 3, a second bearing 2, a rotating rod 4, a sleeve 5 and a top cap. The top of the sleeve 5 is provided with an external thread structure and is screwed with a top cap. The middle of the top cap is connected with the rope. The first bearing 3 is located inside the sleeve 5, and the outer ring of the first bearing 3 is fixed to the inner wall of the sleeve 5. The second bearing 2 is located above the horizontal plate 1, and the outer ring of the second bearing 3 is fixed to the horizontal plate 1. The rotating rod 4 is located between the first bearing 2 and the second bearing 3, and both ends are respectively fixed to the inner rings of the first bearing 2 and the second bearing 3.
[0021] The anti-collision cover 6 is composed of several arc-shaped steel wire skeletons. Both ends of each steel wire skeleton are flat and have through holes, and are fixed into a lantern shape by bolts. The bolts located above are fixed to the horizontal plate 1. The scanner fixing frame 7 is located inside the anti-collision cover 6 and is fixed to the bolts connected to the horizontal plate 1; The anti-collision cover 6 is in an overall lantern shape, reducing the influence on the scanner when scanning the point cloud of the shaft wall.
[0022] The distance between two adjacent steel wire skeletons is less than the width of the scanner; preventing accidents such as the scanner accidentally falling off and dropping into the well.
[0023] The horizontal plate 1 is provided with upper and lower layers and is fixedly connected by bolts. An anti-smashing cover 8 is arranged between the two horizontal plates; The diameter of the anti-smashing cover 8 is much larger than the size of the scanner itself, ensuring that the instrument will not be damaged when floating stones fall, and the instrument is below the anti-smashing cover, which can protect the instrument from being wet by water.
[0024] The centers of gravity of the connecting part, the horizontal plate 1, the anti-smashing cover 8, the anti-collision cover 6 and the scanner fixing frame 7 are all on the same vertical line; ensuring that the center of gravity of the entire device is vertically downward and will not tilt.
[0025] During use, install the scanner on the scanner fixing frame 7 so that it is inside the anti-collision cover 6. Open the steel wire skeletons of the anti-collision cover 6 evenly, ensure that the distance between the two skeletons is less than the width of the scanner, so that the scanner is surrounded by the anti-collision cover 6. Then connect the rope used for lowering through the connecting part. When starting the scanning operation, the scanner will generate a part of torque during self-rotation inside the anti-collision cover 6. These torques will be transmitted to the second bearing 2 through the horizontal plate 1. The rotation of the second bearing 2 will release the torque, and the twisting force of the rope itself during the lowering process will also be released and transmitted to the first bearing 3 through the sleeve 5 for release, eliminating the rotation caused by the twisting force of the rope.
[0026] Through the arrangement of the connecting part, the utility model can effectively overcome the problem of the high-speed rotation of the scanner. The first bearing and the second bearing are used in cooperation to achieve self-rotation unloading. Through the rotation of the bearing, the scanner below can be stable and non-rotating, ensuring the normal scanning operation of the scanner. At the same time, the scanner is installed inside the anti-collision cover through the scanner fixing frame, which can effectively prevent the possibility of damage caused by hitting the wall during the lowering process of the scanner.
[0027] The above are only the preferred and feasible embodiments of the utility model, and do not limit the scope of rights of the utility model. Any equivalent changes made by using the content of the specification and drawings of the utility model are included in the scope of rights of the utility model.
