Description

Technical Field

[0001] The utility model relates to the technical field of underground measurement and point giving, in particular to an underground mine measurement and point giving device. Background Art

[0002] Measuring points is very important in underground mines, which can help miners determine the location, direction and deviation of the pit or tunnel.

[0003] The point-adding method in the prior art is generally that a worker holds a brush and applies paint or other materials to the well wall. However, dust usually adheres to the well wall, which reduces the adhesion of the paint on the well wall. The dust forms a thin film on the well wall, which hinders the direct contact between the paint and the well wall surface. This will reduce the adhesion of the paint and cause the coating to fall off or peel off, making it impossible for the worker to clearly see the positioning mark on the well wall.

[0004] Therefore, it is necessary to design an underground mine measurement and pointing device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a mine underground measurement point giving device.

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

[0007] The invention discloses an underground measuring and giving point device for mines, comprising a spray gun, a nozzle of the spray gun is fixedly sleeved with a fixed cylinder, a sliding sleeve is slidably sleeved on the fixed cylinder, one end of the sliding sleeve is provided with a plurality of slots, the fixed cylinder is provided with an air supply component, and the sliding sleeve is provided with an injection component.

[0008] As a preferred technical solution of the utility model, the air supply assembly includes a sealing cylinder, a sliding plug, a spring and a plurality of connecting rods. The sealing cylinder is fixedly sleeved on the fixed cylinder, the sliding plug is sealingly slidably connected to the inner surface of the sealing cylinder, one end of the spring is connected to the inner surface of the sealing cylinder, and the other end is connected to the sliding plug, one end of a plurality of the connecting rods are fixedly connected to the sliding plug, and the other ends of a plurality of the connecting rods are connected to the sliding sleeve.

[0009] As a preferred technical solution of the utility model, the jet assembly includes an annular jet pipe, a plurality of jet holes and a connecting pipe. The annular jet pipe is fixed to the inner surface of the sliding sleeve, and the plurality of jet holes are opened on the annular jet pipe. One end of the connecting pipe is connected to the annular jet pipe, and the other end is connected to the sealing tube.

[0010] As a preferred technical solution of the utility model, the inner ring of the sliding sleeve and the outer surface of the fixed sleeve are in contact with each other.

[0011] As a preferred technical solution of the utility model, a plurality of the air injection holes are evenly distributed on the annular air injection pipe.

[0012] As a preferred technical solution of the utility model, a container for placing paint is provided on the spray gun.

[0013] The utility model has the following beneficial effects:

[0014] By using an annular jet tube with several jet holes, the device can effectively blow away the dust on the well wall. This cleaning mechanism ensures the cleanliness of the well wall and provides a good foundation for subsequent marking operations. By first cleaning the dust on the well wall and then spraying paint, the adhesion strength of the paint on the well wall can be significantly improved. This can effectively prevent the positioning mark from falling off the well wall and ensure long-term marking effects. Since the well wall is cleaned more thoroughly, the paint adheres more firmly, which not only improves the accuracy of the marking, but also ensures the durability of the marking in harsh environments.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , a mine underground measuring and pointing device includes a spray gun 1, on which a container for placing paint is provided. The specific structure and working principle of the spray gun 1 are not the innovative part of the present technical solution, and are not shown in the figure, and will not be described in detail here. A fixed sleeve 2 is fixedly provided on the nozzle of the spray gun 1, and a sliding sleeve 3 is slidably provided on the fixed sleeve 2. The inner ring of the sliding sleeve 3 is fitted with the outer surface of the fixed sleeve 2, and a plurality of grooves 4 are provided at one end of the sliding sleeve 3.

[0021] An air supply assembly is provided on the fixed cylinder 2, and the air supply assembly includes a sealing cylinder 51, a sliding plug 52, a spring 53 and a plurality of connecting rods 54. The sealing cylinder 51 is fixedly sleeved on the fixed cylinder 2, and the sliding plug 52 is sealingly and slidably connected to the inner surface of the sealing cylinder 51. One end of the spring 53 is connected to the inner surface of the sealing cylinder 51, and the other end is connected to the sliding plug 52. One ends of the plurality of connecting rods 54 are fixedly connected to the sliding plug 52, and the other ends of the plurality of connecting rods 54 are connected to the sliding sleeve 3. The staff presses the spray gun 1 to move the spray gun 1 toward the well wall. In this process, the sliding sleeve 3 will move through the plurality of connecting rods 54, so that the sliding plug 52 moves inside the sealing cylinder 51.

[0022] The sliding sleeve 3 is provided with an injection assembly, which includes an annular injection pipe 61, a plurality of injection holes 62 and a connecting pipe 63. The annular injection pipe 61 is fixed to the inner surface of the sliding sleeve 3. The plurality of injection holes 62 are all opened on the annular injection pipe 61. The plurality of injection holes 62 are evenly distributed on the annular injection pipe 61. One end of the connecting pipe 63 is connected to the annular injection pipe 61, and the other end is connected to the sealing tube 51. The sliding plug 52 can press the gas in the sealing tube 51 into the interior of the annular injection pipe 61 through the connecting pipe 63 during the movement. Then, the gas will be injected onto the well wall through the plurality of injection holes 62. The gas injected from the plurality of injection holes 62 can blow away the dust attached to the well wall, thereby cleaning the dust on the well wall.

[0023] The specific working principle of the utility model is as follows:

[0024] When the underground mine measuring point-giving device proposed by the utility model is in use, the worker holds the spray gun 1 and descends into the well. When the marking position is reached, the worker first aims one end of the sliding sleeve 3 at the well wall, and then presses the spray gun 1 to move the spray gun 1 toward the well wall. In this process, the sliding sleeve 3 will move through a plurality of connecting rods 54, so that the sliding plug 52 moves inside the sealing tube 51. During the movement, the sliding plug 52 can press the gas in the sealing tube 51 into the inside of the annular injection pipe 61 through the connecting pipe 63. Then, the gas will be sprayed onto the well wall through a plurality of injection holes 62. The gas sprayed from the plurality of injection holes 62 can blow away the dust attached to the well wall, thereby cleaning the dust on the well wall. The worker can ensure the cleaning effect of the well wall dust by pressing the spray gun 1 multiple times. After cleaning, the worker uses the spray gun 1 to spray paint on the well wall, thereby ensuring the strength of the paint adhering to the well wall and preventing the positioning mark from falling off the well wall.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
