Description

Technical Field

[0001] This utility model relates to the field of surveying and construction technology in underground mining engineering, and in particular to a graduated rotary spray painting device for marking the outline of a three-center arch in an underground roadway. Background Technology

[0002] In underground tunnel construction, a three-center arch cross-section is often used as the outline shape for tunnel support. Traditional methods for marking tunnel outlines typically employ the "line method" or the "three-point method." 1. Wire pulling method: This method requires the cooperation of multiple people. A thin wire is fixed at the intersection of the tunnel centerline and the waistline (the center point of the arch). The wire is pulled to the side of the tunnel according to different radii and marked point by point. This method is inefficient and the accuracy is greatly affected by the tension of the wire and human factors.

[0003] 2. Three-point method: The coordinates of the key points of the three-center arch (such as the arch crown, arch starting point, and arch foot) need to be calculated first, and then the total station or laser pointer is used to lay out the points one by one. The operation is complicated, highly dependent on the instrument, and has poor adaptability in dusty and humid underground environments.

[0004] Both of these methods suffer from low efficiency, unstable accuracy, reliance on multiple people or complex instruments, and inconvenience in operation in narrow tunnels. There is an urgent need for a simple, easily operable, and reliable rotary spray painting device for marking the outline of a three-centered arch. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a graduated rotary spray painting device for marking the outline of a three-center arch in underground roadways.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A graduated rotary spray painting device for marking the outline of a three-center arch in an underground roadway includes a telescopic rod and a clamping assembly fixed to the upper end of the telescopic rod. The clamping assembly is used to quickly install a self-spraying paint can. The surface of the clamping assembly is provided with a pressing component for pressing the self-spraying paint can. The telescopic rod rotates through a center positioning component, which is adjustablely mounted on the surface of the outer rod. The clamping assembly includes a base plate fixed to the upper end of the outer rod and a positioning plate fixed to the upper surface of the base plate. The positioning plate is arc-shaped and matches the diameter of the spray paint can. The spray paint can is fixed to the surface of the positioning plate by two clamps.

[0007] In some embodiments, the telescopic rod includes an outer rod and an inner rod that slides inside the outer rod, and the surface of the outer rod is provided with scale lines.

[0008] In some embodiments, the pressing assembly includes a support frame fixed to the surface of a positioning plate and a rocker arm that rotates on the inner wall of the support frame via a pivot. The length of the end of the rocker arm near the spray paint can is shorter than the length of the end of the rocker arm away from the spray paint can. The rocker arm presses the spray paint can by pulling a rope.

[0009] In some embodiments, the inner wall of the support frame is rotatably equipped with a guide wheel for changing the direction of the pull rope, the lower surface of the base plate is fixed with a guide tube communicating with the outer rod, one end of the pull rope is fixed to the longer end of the rocker, the other end of the pull rope passes around the guide wheel and through the guide tube into the interior of the telescopic rod, and a pull block is fixed to the lower end of the pull rope.

[0010] In some embodiments, the center positioning component is a pressure suction cup, which includes a fixed plate and a first collar that rotates at the center of the fixed plate. The first collar is sleeved on the surface of the outer rod. Two suction cup components and two support feet are symmetrically arranged on the surface of the fixed plate, and the suction cup components and support feet are arranged diagonally.

[0011] In some embodiments, the center positioning component is an adhesive disc, which includes an adhesive pad and a connecting disc connected to the adhesive pad. A second ring is rotatably mounted on the side of the connecting disc away from the adhesive pad. The second ring is sleeved on the surface of the outer rod. Multiple threaded holes are formed on the surfaces of the connecting disc and the adhesive pad.

[0012] In some embodiments, the center positioning component is a magnetic chuck, which includes a fixed shell and a plurality of magnetic seats fixed to the inner wall of the fixed shell. A third ring is rotatably located at the center of one side of the fixed shell, and the third ring is sleeved on the surface of the outer rod. An iron sheet is fixed to the side of the fixed shell away from the third ring.

[0013] In some embodiments, a gear is fixed to the knob surface of the magnetic base, and an end face toothed ring that meshes with the gear is rotatably mounted on the inner wall of the fixed housing. A lever is fixed to the surface of the end face toothed ring.

[0014] Compared with the prior art, the present invention provides a graduated rotary spray painting device for marking the outline of a three-center arch in underground roadways, which has the following beneficial effects.

[0015] 1. This utility model, by installing a self-spraying paint can in a clamping assembly, allows the telescopic rod to rotate and swing around the center positioning assembly.

[0036] 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.

[0037] Example 1: Reference Figure 1-9 A graduated rotary spray painting device for marking the outline of a three-center arch in an underground roadway includes a telescopic rod 1 and a clamping assembly 2 fixed to the upper end of the telescopic rod 1. The clamping assembly 2 is used to quickly install a self-spraying paint can 3. The surface of the clamping assembly 2 is provided with a pressing assembly 4 for pressing the self-spraying paint can 3. The telescopic rod 1 rotates through a center positioning assembly.

[0038] It is understandable that by installing the spray paint can 3 in the clamping assembly 2, the telescopic rod 1 rotates and swings around the center positioning assembly. During the rotation, the spray paint can 3 sprays out paint mist by pressing the assembly 4, thereby quickly drawing an arc-shaped trajectory line.

[0039] Specifically, the telescopic rod 1 includes an outer rod 101 and an inner rod 102 that slides inside the outer rod 101. The outer rod 101 has scale lines 103 on its surface, and a center positioning component is adjustablely mounted on the surface of the outer rod 101.

[0040] It is understandable that by setting the telescopic rod 1, the length can be easily adjusted to facilitate operation. By setting the scale line 103, the position of the center positioning component can be accurately adjusted, thereby adjusting the rotation center of the spray paint can 3, and arcs of different diameters can be drawn.

[0041] Specifically, the clamping assembly 2 includes a base plate 201 fixed to the upper end of the outer rod 101 and a positioning plate 202 fixed to the upper surface of the base plate 201. The base plate 201 is set perpendicular to the outer rod 101. The positioning plate 202 is arc-shaped and matches the diameter of the spray paint can 3. The two ends of the positioning plate 202 are respectively hinged with clamps 203, and the other ends of the two clamps 203 are fastened together by bolts.

[0042] Understandably, by setting up the clamping assembly 2, the position of the spray paint can 3 is positioned under the action of the positioning plate 202, so that the two clamps 203 rotate and clamp onto the surface of the spray paint can 3, and the outer ends of the two clamps 203 are fixed by bolts, thereby quickly clamping and positioning the spray paint can 3.

[0043] Specifically, the pressing component 4 includes a support frame 401 fixed to the surface of the positioning plate 202 and a rocker plate 402 that rotates on the inner wall of the support frame 401 via a rotating shaft. The length of the end of the rocker plate 402 near the spray paint can 3 is shorter than the length of the end of the rocker plate 402 away from the spray paint can 3. A torsion spring 4021 for separating the rocker plate 402 from the spray paint can 3 is sleeved on the surface of the rotating shaft. The rocker plate 402 presses the spray paint can 3 by pulling the rope 403. The inner wall of the support frame 401 has a rotatable guide wheel 404 for changing the direction of the pull rope 403. The lower surface of the base plate 201 is fixed with a guide tube 405. One end of the guide tube 405 is connected to the outer rod 101. One end of the pull rope 403 is fixed to the longer end of the rocker 402. The height of the guide wheel 404 is higher than the height of the rocker 402. The other end of the pull rope 403 passes around the guide wheel 404 and passes through the guide tube 405 into the interior of the telescopic rod 1. The inner wall of the inner rod 102 has a vertically sliding pull block 406. The other end of the pull rope 403 is fixed to the upper surface of the pull block 406. The surface of the inner rod 102 is provided with a through groove 407 for the vertical sliding of the pull block 406.

[0044] Understandably, when the spray paint can 3 needs to spray paint mist, the pull block 406 is pushed down to slide, thereby pulling the pull rope 403. The pull rope 403 drives one end of the rocker 402 to rise through the guide wheel 404, thereby pressing the other end of the rocker 402 onto the spray paint can 3 and spraying paint mist. The length of the end of the rocker 402 closest to the spray paint can 3 is set to be less than the length of the end of the rocker 402 furthest from the spray paint can 3, using the lever principle to achieve the purpose of saving effort. Since the length of the telescopic rod 1 can be adjusted, after the inner rod 102 slides inside the outer rod 101, the pull block 406 is adjusted through the through groove 407 to keep the pull rope 403 taut.

[0045] Specifically, the center positioning component is a pressure suction cup 5, which includes a fixed plate 501 and a first collar 502 that rotates at the center of the fixed plate 501. The first collar 502 is sleeved on the surface of the outer rod 101 and is fixed to the surface of the outer rod 101 by fastening bolts. Two suction cup components 503 and two support feet 504 are symmetrically arranged on the surface of the fixed plate 501. The suction cup components 503 and the support feet 504 are arranged diagonally. The suction cup assembly 503 includes a horn cover 5031 fixed to the back of the fixed plate 501 and a rubber suction cup 5032 fixed to the inner wall of the horn cover 5031. A threaded rod 5033 is threadedly connected to the surface of the fixed plate 501, and one end of the threaded rod 5033 rotates on the surface of the rubber suction cup 5032.

[0046] Understandably, by setting the center positioning component as a pressure suction cup 5, it is suitable for flat concrete or sprayed tunnel surfaces; by rotating the threaded rod 5033, the rubber suction cup 5032 is deformed, causing the rubber suction cup 5032 to generate negative pressure and adhere to the tunnel surface; by setting two support legs 504, the balance of the fixed plate 501 is improved, and the telescopic rod 1 rotates on the surface of the fixed plate 501 through the first collar 502, thereby driving the self-spraying paint can 3 to swing around the fixed plate 501 as the center, thus drawing an arc.

[0047] Specifically, a positioning rod 6 is fixed at the center of the back of the fixed plate 501.

[0048] It is understandable that by setting the positioning rod 6, positioning holes can be pre-drilled on the surface of the tunnel. When placing the fixed plate 501, the positioning rod 6 can be inserted into the positioning hole, thereby improving the center positioning accuracy.

[0049] Example 2: Reference Figure 10-11 The difference from the above embodiments is: The center positioning component is an adhesive disc 7, which includes an adhesive disc 701 and a connecting disc 702 connected to the adhesive disc 701. An adhesive layer 7011 is provided on the side of the adhesive disc 701 away from the connecting disc 702 for adhering to the roadway. A second collar 703 is rotatably provided on the side of the connecting disc 702 away from the adhesive disc 701. The second collar 703 is sleeved on the surface of the outer rod 101 and fixed to the surface of the outer rod 101 by fastening bolts. Multiple threaded holes 704 are provided on the surfaces of the connecting disc 702 and the adhesive disc 701. A positioning rod 6 is fixed on the side of the connecting disc 702 facing the adhesive disc 701. A through hole is provided on the surface of the adhesive disc 701 to avoid the positioning rod 6.

[0050] It is understandable that by setting the adhesive disc 7, it can be adapted to the installation of most tunnel surfaces. The adhesive disc 701 is pasted into the tunnel, and the connecting disc 702 is fixed to the surface of the adhesive disc 701 by bolts and multiple threaded holes 704. At the same time, the positioning rod 6 is inserted into the positioning hole to complete the positioning and installation of the telescopic rod 1. The adhesive disc 701 is a disposable item.

[0051] Example 3: Reference Figure 12-15 The difference from the above embodiments is: The center positioning component is a magnetic chuck 8, which includes a fixed shell 801 and multiple magnetic seats 803 fixed to the inner wall of the fixed shell 801. A third ring 802 is rotatably located at the center of one side of the fixed shell 801. The third ring 802 is sleeved on the surface of the outer rod 101 and fixed by fastening bolts. An iron piece 8011 is fixed on the side of the fixed shell 801 away from the third ring 802. The magnetic surfaces of the multiple magnetic seats 803 are in contact with the iron piece 8011. A gear 804 is fixed on the knob surface of the magnetic seat 803. An end face toothed ring 805 that meshes with the gear 804 is rotatably located on the inner wall of the fixed shell 801. A lever 806 is fixed on the surface of the end face toothed ring 805.

[0052] It is understandable that by setting up magnetic chucks 8, it can be adapted to be fixed on the surface of the tunnel supported by metal mesh or steel strip. By setting up multiple magnetic seats 803, the end face gear ring 805 is rotated by a dial, thereby causing multiple gears 804 to rotate the knob of the magnetic seat 803, so that the magnetic seat 803 generates magnetic force, which is magnetically attracted to the tunnel surface through the iron sheet 8011; (the principle of the magnetic seat 803 is as follows: the magnetic seat 803 contains a cylinder, in which a long strip of permanent magnet or constant magnet is placed, and the outer base position is a...) The block of soft magnetic material refers to a ferrite material that is easily magnetized and demagnetized under a weak magnetic field. By turning the knob, the magnet inside is rotated. When the two poles of the magnet are vertical, that is, when the N or S pole of the magnet is directly facing the soft magnetic material base, it is magnetized and has a strong magnetism in this direction, so it can be used to attract steel surfaces. When the two poles of the magnet are horizontal, that is, when the middle of the two poles of the magnet is directly facing the soft magnetic material base, the middle of the long bar magnet has only a very small magnetism, which can be ignored, and it will not be magnetized, so there is no magnetic force at this time.

[0053] In this invention, when drawing the outline of a three-centered arch, the spray paint can 3 is installed in the clamping assembly 2 to fix it. When drawing the middle section arc 12, the center positioning assembly is fixed at the intersection of the centerline 9 and the waistline 10 of the tunnel design, allowing the telescopic rod 1 to slide on the surface of the center positioning assembly. The distance between the spray paint can 3 and the center positioning assembly is adjusted by the scale line 103, thereby adjusting the rotation radius. Then, while rotating the telescopic rod 1, the worker presses the spray paint can 3 with the pressing assembly 4 to spray paint mist, drawing the arc during the rotation. Then, when drawing the two side arcs 13, the center positions of the two side arcs 13 are marked on the arching line 11, and the center positioning assembly is fixed on the center. The steps of drawing the middle section arc 12 are repeated, and the side arcs 13 are drawn at both ends of the middle section arc 12 to form the outline of a three-centered arch (see reference). Figure 16-17 By drawing the outline of the three-center arch using the above structure, the laying-out time is greatly shortened and the construction efficiency is improved. The circular positioning component slides on the surface of the telescopic rod 1, which makes it easy to adjust the drawing radius. With the circular positioning component as the rotation center, the rotation trajectory naturally forms an arc, avoiding human error and wire deformation error in the string method.
