Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to an auxiliary device for spraying paint dots during tunnel construction. Background Technology

[0002] During tunnel construction, it is often necessary to spray paint on the inner wall of the tunnel to facilitate subsequent operations. For the bottom of the tunnel, the operators can directly spray paint on the marked areas. However, for the marked areas at higher levels, the operators often need to carry a ladder. Carrying and moving the ladder increases the labor intensity of the operators, and the frequent up and down of the ladder for marking operations also poses certain safety hazards.

[0003] Therefore, existing auxiliary devices for spraying paint in tunnel construction cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for spraying paint dots in tunnel construction. Through the cooperation of the support rod, connecting frame, limiting clamp and pressing mechanism, the self-spraying paint is extended to the dotting position, and then the self-spraying paint is sprayed and pressed by the pressing mechanism, which is convenient to operate.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a spray painting auxiliary device for tunnel construction, comprising a support rod, a connecting frame, a limiting clamp, and a pressing mechanism, characterized in that: the limiting clamp comprises an arc-shaped clamp body, clamping arms, and limiting plates; two clamping arms are disposed at the open end of the arc-shaped clamp body; at least two limiting plates are disposed at the bottom of the arc-shaped clamp body, and there is a gap between the limiting plates; the arc-shaped end of the arc-shaped clamp body is hinged to one end of the support rod through the connecting frame;

[0006] The pressing mechanism includes a brake lever, a pull cable, a guide cylinder, a pressing plate, and a spring. The brake lever is mounted on a support rod. The two guide cylinders are respectively mounted on the connecting frame and the pressing plate. One end of the pressing plate is hinged to the connecting frame, and the other end of the pressing plate passes through the arc-shaped end of the arc-shaped clamp through a guide groove on the arc-shaped clamp and extends into it. One end of the pull cable is connected to the brake lever, and the other end of the pull cable passes through the guide cylinder on the connecting frame and the spring and then connects to the guide cylinder on the pressing plate. The two ends of the spring abut against the two guide cylinders.

[0007] Furthermore, the connecting frame is hinged to one end of the support rod via a limiting hinge.

[0008] Furthermore, a screw is inserted into the guide cylinder on the pressing plate, and the end of the screw inside the spring is connected to the pull wire through a connecting ring. The other end of the screw is screwed to the adjusting nut.

[0009] Furthermore, the pressing plate located in the arc-shaped clamp is provided with a screw hole, and an adjusting bolt is screwed into the screw hole.

[0010] Furthermore, the support rod is a telescopic rod.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This application uses a clamping arm to move the arc-shaped clamping body to the limiting plate, so that it is locked at the opening of the spray paint, thus fixing the spray paint. Then, the orientation of the spray paint is adjusted by the connecting rod, and the spray paint is lifted to a suitable position by the support rod. After the brake lever is gripped and the cable is pulled, the spring is compressed and the pressing plate is pulled down to press the spray paint pressing cover, thus realizing the operation of the spray paint.

[0013] 2. In this application, the spring is set between two guide cylinders, the pull rope passes through the spring, and the brake lever is automatically reset by the spring. The wire also guides and limits the compression direction of the spring to prevent the spring from disengaging.

[0014] 3. In this application, the connecting frame and one end of the support rod are hinged by a limiting hinge, which can adjust the rotation angle of the connecting frame and automatically limit it. When a rotational force is applied again, the connecting frame continues to rotate and automatically limits itself, which makes it easy to control and adjust the spraying direction of the self-spraying paint.

[0015] 4. In this application, a screw is inserted into the guide cylinder on the pressing plate. The length of the screw extending out of the guide cylinder is adjusted by adjusting the nut, thereby realizing the tensioning operation of the pull line, compressing the spring, and further rotating the pressing plate towards the spray paint, reducing the distance between the pressing plate and the spray paint.

[0016] 5. An adjusting bolt is screwed into the screw hole in this application. By turning the adjusting bolt, the distance between the pressing plate and the spray paint can be further adjusted to accommodate spray paint at different heights.

[0017] 6. The support rod in this application is a telescopic rod, which can be retracted and is easy to carry.

[0026] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0027] like Figure 1-3 As shown, a spray painting auxiliary device for tunnel construction includes a support rod 1, a connecting frame 2, a limiting clamp and a pressing mechanism. The limiting clamp includes an arc-shaped clamp body 3, clamp arms 4 and limiting plates 5. Two clamp arms 4 are set at the open end of the arc-shaped clamp body 3. There are at least two limiting plates 5, which are set at the bottom inside the arc-shaped clamp body 3 and there is a gap between the limiting plates 5. The arc-shaped end of the arc-shaped clamp body 3 is hinged to one end of the support rod 1 through the connecting frame 2.

[0028] The pressing mechanism includes a brake lever 6, a pull cable 7, guide cylinders 8, a pressing plate 9, and a spring 10. The brake lever 6 is mounted on the support rod 1. The two guide cylinders 8 are respectively mounted on the connecting frame 2 and the pressing plate 9. One end of the pressing plate 9 is hinged to the connecting frame 2, and the other end of the pressing plate 9 passes through the guide groove 11 on the arc-shaped clamp 3, passes through the arc-shaped end of the clamp 3, and extends into it. One end of the pull cable 7 is connected to the brake lever 6, and the other end of the pull cable 7 passes through the guide cylinders 8 and the spring 10 on the connecting frame 2. The spring 10 is connected to the guide cylinder 8 on the pressing plate 9, and the two ends of the spring 10 abut against the two guide cylinders 8. The arc-shaped clamp 3 is driven by the clamping arm 4 to move the limiting plate 5, so that it is locked at the opening of the spray paint, thus fixing the spray paint. Then, the orientation of the spray paint is adjusted by the connecting rod. After the spray paint is lifted to the appropriate position by the support rod 1, the brake lever 6 is squeezed and the pull cable 7 is pulled. After the spring 10 is compressed, the pressing plate 9 is pulled down to press the spray paint pressing cover, thus realizing the operation of the spray paint.

[0029] The spring 10 is positioned between the two guide cylinders 8. The pull rope passes through the spring 10 and the brake lever 6 is automatically reset through the spring 10. The wire also guides and limits the compression direction of the spring 10 to prevent the spring 10 from disengaging.

[0030] The connecting frame 2 is hinged to one end of the support rod 1 via a limiting hinge 12. The connecting frame 2 and the support rod 1 are hinged to one end via a limiting hinge 12, which can adjust the rotation angle of the connecting frame 2 and automatically limit it. When a rotational force is applied, the connecting frame 2 continues to rotate and automatically limits itself, which makes it easy to control and adjust the spraying direction of the self-spraying paint. Example 2

[0031] like Figure 2-3 As shown, this embodiment is obtained by adding technical features such as screw 13 on the basis of embodiment one. The other technical features are the same as those in embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that: a screw 13 is inserted into the guide cylinder 8 on the pressing plate 9, and the end of the screw 13 inside the spring 10 is connected to the pull wire 7 through the connecting ring 14. The other end of the screw 13 is screwed to the adjusting nut 15.

[0032] In this embodiment, a screw 13 is inserted into the guide cylinder 8 on the pressing plate 9. The length of the screw 13 extending out of the guide cylinder 8 is adjusted by adjusting the nut 15, thereby achieving the tensioning operation of the pull wire 7, compressing the spring 10, and further causing the pressing plate 9 to rotate towards the spray paint, reducing the distance between the pressing plate 9 and the spray paint. Example 3

[0033] like Figure 1-3As shown, this embodiment is obtained by adding technical features such as adjusting bolt 17 on the basis of embodiment 2. The other technical features are the same as those in embodiment 2. The similarities will not be repeated here. The difference between this embodiment and embodiment 2 is that the pressing plate 9 in the arc-shaped clamp 3 is provided with a screw hole 16, and the adjusting bolt 17 is screwed into the screw hole 16.

[0034] In this embodiment, an adjusting bolt 17 is screwed into the screw hole 16. By turning the adjusting bolt 17, the distance between the pressing plate 9 and the spray paint can be further adjusted to accommodate spray paint at different heights. Example 4

[0035] like Figure 1-3 As shown, this embodiment is obtained by further describing the technical features of the support rod 1 based on the third embodiment. The other technical features are the same as those in the third embodiment, and the similarities will not be repeated here. The difference between this embodiment and the third embodiment is that the support rod 1 is a telescopic rod.

[0036] In this embodiment, the support rod 1 is a telescopic rod that can be retracted and is easy to carry.

[0037] The usage process of the technical solution formed by the above embodiments is as follows: One hand holds the two clamping arms 4 and moves them towards each other, causing the arc-shaped clamping body 3 to move along with the limiting plate 5, widening the opening of the arc-shaped clamping body 3. The other hand holds the spray paint and inserts it into the limiting plate 5 through the opening. The pressure on the clamping arms 4 is then released, causing the arc-shaped clamping body 3 to return to its original position, and the limiting plate 5 is locked onto the spraying end of the spray paint, thus fixing the spray paint. The adjusting nut 15 is adjusted according to the distance between the adjusting bolt 17 and the pressing part of the spray paint. Adjust the bolt 17 to make the distance between the adjusting bolt 17 and the self-spraying paint pressing part appropriate. Adjust the length of the support rod 1 and the rotation angle of the connecting frame 2 according to the marking position. After extending the self-spraying paint to the marking position through the support rod 1, hold the brake lever 6 and pull the pull cable 7. The pull cable 7 pulls the pressing plate 9 to move, the spring 10 is compressed, and the adjusting bolt 17 presses on the self-spraying paint pressing part. The self-spraying paint sprays out paint to realize the marking operation. After releasing the pressure on the brake lever 6, the spring 10 returns to its original position and drives the pressing plate 9 and the brake lever 6 to return to their original positions.

[0038] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
