Description

Technical Field

[0001] This utility model relates to the technical field of tunnel deformation detection devices, specifically a substation scanning site marking device for tunnel deformation detection. Background Technology

[0002] In the coal mining industry, the practice of collecting and analyzing surface data and deformation in return airway tunnels generally requires determining scanning control points and setting targets in areas where scene features are not obvious in order to improve scanning accuracy.

[0003] In practical use, the positioning magnetic brackets for target ball support often attract magnetic impurities at the work site, making them extremely difficult to clean and easily affecting measurement accuracy. Furthermore, magnetic planar brackets require their base to be bonded to the target hole, making it difficult to separate the bracket from the hole after the adhesive dries. Cleaning residual adhesive after separation can easily cause the magnetic ring to shift or fall off. Additionally, the target ball support base is fixed in pre-drilled holes in the mine; if the holes are too large, the base's fixation is not secure, causing the target ball to shake and affecting measurement accuracy. Therefore, we propose a substation scanning site marking device for roadway deformation detection to solve these problems. Utility Model Content

[0007] The rotating seat and the first connecting rod are connected by a linkage structure. When the rotating seat rotates, it drives the first connecting rod to move horizontally, thereby pushing the second connecting rod to move horizontally.

[0013] The substation scanning site marking device for tunnel deformation detection as described above: one end of the second connecting rod is provided with an insertion rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: a rotating seat is rotatably arranged on the base, a target ball is arranged on the rotating seat, an insertion block is arranged on the base, a rectangular groove is rotatably arranged on the inner wall of the insertion block, rectangular plates are movably engaged at both ends of the rectangular groove, a first connecting rod is hinged to one end of one rectangular plate and is arranged through the housing of the insertion block, a second connecting rod is hinged to one end of the other rectangular plate and is arranged through the housing of the insertion block, and a spring is arranged between one end of one rectangular plate and the inner wall of the insertion block;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-6 As an embodiment of this utility model, a substation scanning station marking device for roadway deformation detection includes a base 1, a rotating seat 2 rotatably mounted on the base 1, a target ball 3 mounted on the rotating seat 2, an insert block 9 mounted on the base 1, a rectangular groove 10 rotatably mounted on the inner wall of the insert block 9, rectangular plates 11 movably engaged at both ends of the rectangular groove 10, a first connecting rod 13 that penetrates the housing of the insert block 9 is hinged to one end of one rectangular plate 11, a second connecting rod 14 that penetrates the housing of the insert block 9 is hinged to one end of the other rectangular plate 11, and a spring 12 is provided between one end of the rectangular plate 11 and the inner wall of the insert block 9.

[0025] The rotating seat 2 and the first connecting rod 13 are connected by a linkage structure. When the rotating seat 2 rotates, it will drive the first connecting rod 13 to move horizontally, thereby pushing the second connecting rod 14 to move horizontally.

[0026] In this embodiment, the rotating seat 2 rotates while driving the first connecting rod 13 to move horizontally, thereby pushing the second connecting rod 14 to move horizontally. When installing the target ball 3, the insert 9 is inserted into the hole. Rotating the rotating seat 2 allows multiple second connecting rods 14 to open outward and insert into the inner wall of the hole, fixing the base 1 in the hole. This achieves the fixed-point installation of the target ball 3. This structure replaces traditional adhesive, making the base more firmly and reliably fixed. At the same time, controlling the extension length of the second connecting rod 14 can adapt to the installation in holes of different diameters.

[0027] As a further embodiment of this utility model, the rotating seat 2 is provided with a threaded hole, and the bottom of the target ball 3 is provided with a bolt that is threadedly connected to the threaded hole. The target ball 3 can be detachably installed on the rotating seat 2 through the engagement of the bolt threaded hole.

[0028] In this embodiment, the target ball 3 is detachably mounted on the rotating seat 2 by means of a bolt thread hole, which makes the target ball 3 easy to disassemble and install, and easy to disassemble, replace or repair later.

[0029] As a further embodiment of this utility model, the linkage structure includes multiple arc-shaped grooves 4 formed on the rotating seat 2 at equal angles. A limit rod 5 is movably engaged in the arc-shaped groove 4. A push rod 6 is provided on the limit rod 5. A limit plate 8 is provided at one end of the push rod 6 and movably passes through the base 1. A push plate 7 is provided at the other end of the push rod 6.

[0030] In this embodiment, when installing the target ball 3, the base 1 is first fixed, and then the rotating seat 2 is rotated. The limiting rod 5 slides in the arc groove 4, which drives the limiting rod 5 to move horizontally, thereby driving the push rod 6 at the bottom of the limiting rod 5 to move horizontally. Thus, the push plate 7 at one end of the push rod 6 pushes the first connecting rod 13, causing the first connecting rod 13 to move horizontally.

[0031] As a further embodiment of this utility model, the centerlines of the push rod 6, push plate 7, first connecting rod 13, and spring 12 are arranged on the same straight line.

[0032] In this embodiment, when the push rod 6 moves, it will drive the push plate 7 to move horizontally. The push plate 7 will push the first connecting rod 13, causing the first connecting rod 13 to slide on the insert block 9, thereby pushing one end of the rectangular plate 11 to rotate.

[0033] As a further embodiment of this utility model, the bottom end of the plug block 9 is provided with a plug 16, which adopts a conical top design.

[0034] In this embodiment, the conical top design of the plug 16 facilitates easy insertion of the plug 16 into the hole, increasing the ease of installation of the target ball 3.

[0035] As a further embodiment of this utility model, the insert 9 is provided with limiting holes whose inner surface dimensions are adapted to the outer surface dimensions of the first connecting rod 13 and the second connecting rod 14, and the first connecting rod 13 and the second connecting rod 14 are movably engaged inside the limiting holes.

[0036] In this embodiment, the first link 13 and the second link 14 are movably engaged inside the limiting hole, which can limit the movement of the first link 13 and the second link 14 when they move horizontally, thus preventing tilting during movement.

[0037] As a further embodiment of this utility model, a plug rod 15 is provided at one end of the second connecting rod 14.

[0038] In this embodiment, a plug rod 15 is provided at one end of the second connecting rod 14, which can be inserted more stably into the inner wall of the hole when the second connecting rod 14 extends outward.

[0039] When installing the target ball 3, insert the insert block 9 into the hole, first press and fix the base 1 at the opening, rotate the rotating seat 2, and use the limiting rod 5 to slide in the arc groove 4 to drive the limiting rod 5 to move horizontally, thereby driving the push rod 6 at the bottom of the limiting rod 5 to move horizontally. Then, use the push plate 7 at one end of the push rod 6 to push the first connecting rod 13 to move horizontally. The first connecting rod 13 will push the rectangular plate 11 to rotate, drive the rectangular groove 10 to rotate, thereby driving the second connecting rod 14 to move horizontally, pushing multiple insert rods 15 to extend outward and insert into the inner wall of the hole, so that the base 1 is fixed in the hole, thereby realizing the fixed-point installation of the target ball 3. In addition, when removing the base 1, rotate the rotating seat 2 in the opposite direction so that the push plate 7 no longer pushes the first connecting rod 13. Under the action of the spring 12, the spring 12 elastically resets, thereby pushing the rectangular plate 11 to move, so that the insertion rod 15 is pulled out from the inner wall of the hole, and the insertion block 9 is released from the fixation between itself and the inner wall of the hole, thus facilitating the quick disassembly of this device.

[0040] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
