Description

Technical Field

[0001] The present invention relates to the technical field of tunnel maintenance, and particularly relates to a standardized construction device integrating cutting, grooving and grinding. Background Art

[0002] The main use of this device is an integrated device for edge cutting, grooving and surface grinding in the later maintenance of tunnel anchor grooves.

[0003] For the later maintenance of traditional tunnel anchor grooves, it is necessary to use tools to cut the protective coating on the original tunnel wall, and to cut inclined grooves at the edges. The grooving depth is generally required to be controlled within 5-10 millimeters, and then the protective coating of the anchor groove is ground to the concrete base surface.

[0004] For the later maintenance construction of traditional anchor grooves, all are manual operations by workers. There is no auxiliary tool to assist during the whole construction process. Different proficiency levels of workers will cause problems such as incomplete cutting, unclean cleaning of the original protective coating left at the edges, too shallow or too deep grooving depth, and uneven base surface due to different grinding forces during base surface grinding, and even the situation of needing to repair again. The traditional construction method is time-consuming and laborious, with low standardization, resulting in unqualified acceptance many times, and it will also have a certain impact on the subsequent coating construction of the anchor groove. Therefore, how to make a standardized construction device integrating cutting, grooving and grinding that can solve the problems of the existing technology has become a technical problem to be solved. Summary of the Invention

[0005] Based on the above technical problems, the present invention proposes a construction device that can perform standardized construction and integrates cutting, grooving and grinding.

Adjustable support feet are arranged at the lower part of the support legs, and anti-slip pads are arranged at the bottoms of the adjustable support feet. The anti-slip pads are in contact with the base surface to play an anti-slip role.

[0007] Further, the track is composed of a straight track and an arc track. The length of the straight track can be determined according to the size of the anchor groove, and the arc track matches the radian of the corner of the anchor groove.

[0008] Further, the motion device can be adjusted to a cutting mode and a grooving and grinding mode.

[0009] Further, the cutting mode of the motion device includes a pulley assembly, a first horizontal bracket, a fixed shaft, and springs at the upper and lower ends of the fixed shaft, which are arranged in sequence. At the upper and lower ends of the outer side of the support member of the pulley assembly, there are pulleys that match the straight track and the arc track in the chassis. The fixed shaft is fixed to the inner side of the support member. Springs, a first horizontal bracket, and springs are sleeved on the outer circle of the fixed shaft from top to bottom.

On the inner side of the second horizontal bracket, there are two cylindrical optical axis slide rails up and down. At the upper side of the end of the optical axis slide rail, there are protrusions. The protrusions fit with the notches at the ends of the optical axis slide rails. After being connected and fixed by countersunk screws, a complete optical axis slide rail is formed. The second horizontal bracket and the first horizontal bracket can move up and down together along the fixed shafts and the limit holes on the two groups of support members and can be reset by the springs.

[0011] Further, on the pipe body of the working device, there is a lockable slider that matches the optical axis slide rail. Inside the pipe body, there is an adjustable main shaft of the handle assembly. The adjustable main shaft can slide up and down inside the pipe body. The upper end of the adjustable main shaft is the handheld part of the handle assembly, and the lower end of the adjustable main shaft is the connecting part of the handle assembly.

Specific embodiments

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the content disclosed below.

[0022] The following combines Figures 1 to 10 shown to further illustrate the technical solution of the present invention.

[0023] The first embodiment is as Figures 1 to 10 shown: A standardized construction device integrating cutting, grooving and grinding. The main function of this device is to perform cutting, grooving and grinding operations on the anchor groove D.

[0024] The device includes a chassis A, a moving device B, and a working device C. The chassis A is placed on the base surface E. The moving device B can move along the straight track 2 and the arc track 3 of the chassis A through the pulley assembly 5. The working device C can move horizontally on the moving device B through the lockable slider 1101 on the pipe body 11.

[0025] The described chassis A is provided with a straight track 2 and an arc track 3. Both the straight track 2 and the arc track 3 are composed of two tracks, one on the top and one on the bottom. The straight track 2 and the arc track 3 are connected and fixed by fixing connectors 4 with the same size. The straight track 2 and the arc track 3 are fixed on several support legs 1. An adjustable support foot 101 is arranged at the lower part of the support leg 1, and an anti-slip pad 102 is arranged at the bottom of the adjustable support foot 101. The anti-slip pad 102 contacts the base surface E to play an anti-slip role.

[0026] The described motion device B can be adjusted into a cutting mode and a grooving and grinding mode.

[0027] The cutting mode of the motion device B includes a pulley assembly 5, a first horizontal bracket 6, a fixed shaft 8, and springs 9 at the upper and lower ends of the fixed shaft 8 arranged in sequence. At the upper and lower ends of the outer side of the support member 502 of the pulley assembly 5, pulleys 501 matching the straight track 2 and the arc track 3 in the chassis A are arranged. The fixed shaft 8 is fixed inside the support member 502. Springs 9, a first horizontal bracket 6, and springs 9 are sleeved on the outer circle of the fixed shaft 8 from top to bottom respectively. Two anti-rotation fixed heads 603 are arranged on the outer side of the first horizontal bracket 6. The anti-rotation fixed heads 603 pass through the limiting holes 503 on the support member 502. Two cylindrical optical axis slide rails 602 are arranged on the inner side of the first horizontal bracket 6. A notch 604 and a countersunk head screw 605 are arranged on the upper side of the end of the optical axis slide rail 602. The first horizontal bracket 6 can move up and down along the fixed shaft 8 and the limiting holes 503 on the support member 502 and can be reset by the spring 9.

[0028] The grinding mode of the motion device B is to add another set of pulley assembly 5, a second horizontal bracket 7, a fixed shaft 8, and springs 9 at the upper and lower ends of the fixed shaft 8 on the other side of the cutting mode motion assembly. At the upper and lower ends of the outer side of the support member 502 of the pulley assembly 5, pulleys 501 matching the straight track 2 and the arc track 3 in the chassis A are arranged. The fixed shaft 8 is fixed inside the support member 502. Springs 9, a second horizontal bracket 7, and springs 9 are installed on the outer circle of the fixed shaft 8 from top to bottom respectively. Two anti-rotation fixed heads 703 are arranged on the outer side of the second horizontal bracket 7. The anti-rotation fixed heads 703 pass through the limiting holes 503 on the support member 502. Two cylindrical optical axis slide rails 702 are arranged on the inner side of the second horizontal bracket 7. A convex block 704 is arranged on the upper side of the end of the optical axis slide rail 702. The convex block 704 fits with the notch 604 at the end of the optical axis slide rail 602. After being connected and fixed by the countersunk head screw 605, a complete optical axis slide rail is formed. The second horizontal bracket 7 and the first horizontal bracket 6 can move up and down together along the fixed shaft 8 and the limiting holes 503 on the two groups of support members 502 and can be reset by the spring 9.

[0029] A lockable slider 1101 matching the optical axis slide rail 602 is provided on the pipe body 11 of the working device C. An adjustable main shaft 1001 of the handle assembly 10 is installed inside the pipe body 11. The adjustable main shaft 1001 can slide up and down inside the pipe body 11. The upper end of the adjustable main shaft 1001 is the hand-held part 1003 of the handle assembly 10, and the lower end of the adjustable main shaft 1001 is the connecting part 1002 of the handle assembly 10.

[0030] The connecting part 1002 of the handle assembly 10 is hinged to the connecting part 1201 of the fixed fixture 12. The fixed fixture 12 can rotate around the hinge point. The fixed surface of the fixed fixture 12 uses a fixing bolt 1202 and a fixing ring 1203 to fix the grinding tool 14. The sliding connecting rod 1204 is connected and fixed to the fixed connection point 1205 on the connecting surface of the fixed fixture 12 and the limit hole 1102 on the side of the pipe body 11 through the fixing bolt 1202, so that the fixed fixture 12 can only be rotated and adjusted within a certain angle range, thereby switching the cutting mode and the grinding mode. After the fixed fixture 12 is in place, the fixing bolt 1202 firmly fixes the sliding connecting rod 1204, so that the fixed fixture 12 will not rotate and displace.

[0031] When performing different operations, after adjusting the fixed fixture 12 to a suitable position, the height of the handle assembly 10 can be adjusted, and the adjustable main shaft 1001 of the handle assembly 10 is locked with the fixing screw 1103 on the pipe body 11, so as to fix the position of the fixed fixture 12. The fixed fixture 12 can be adjusted according to different grinding tools 14.

[0032] A guide wheel assembly 13 is also provided on the connecting surface of the fixed fixture 12. The guide wheel sleeve 1303 of the guide wheel assembly 13 is fixedly connected to the fixed fixture 12. The limit shaft 1302 of the universal wheel 1301 passes through the guide wheel sleeve 1303 and is fixed by a positioning bolt 1304.

[0033] The cutting mode operates as follows: Rotate the fixed fixture 12 to a state parallel to the pipe body 11. The wheel blade 1401 of the grinding tool 14 is perpendicular to the base surface E. Press the handle assembly 10 to make the wheel blade 1401 of the grinding tool 14 contact the base surface E. Fix the adjustable spindle 1001 of the handle assembly 10 firmly through the fixing screw 1103 on the fixed pipe body 11. Translate the working device C to make the wheel blade 1401 of the grinding tool 14 coincide with the edge of the anchor slot D. Limit the height of the limiting shaft 1302 of the guide wheel assembly 13. The height difference between the bottom surface of the universal wheel 1301 and the bottom of the wheel blade 1401 of the grinding tool 14 is the grooving depth required for the operation. After fixing the limiting shaft 1302 firmly, the cutting operation can be carried out. The working device C moves circumferentially along the straight track 2 and the arc track 3 of the chassis A with the moving device B to complete the cutting operation.

[0034] The grinding mode operates as follows: Pull up the handle assembly 10, rotate the fixed fixture 12 to a state perpendicular to the pipe body 11. The wheel blade 1401 of the grinding tool 14 is parallel to the anchor slot D. Press the handle assembly 10 to make a distance of about 10 millimeters between the wheel blade 1401 of the grinding tool 14 and the anchor slot D. Fix the adjustable spindle 1001 of the handle assembly 10 firmly through the fixing screw 1103 on the fixed pipe body 11. Install another set of pulley assemblies 5 on the chassis A. Connect the optical axis slide rail 702 of the second horizontal bracket 7 and the optical axis slide rail 602 of the first horizontal bracket 6 and fix them through the countersunk head screw 605 to form two complete optical axis slide rails. Move the working device to the working surface of the anchor slot D. The working device can be translated up, down, left, and right to complete the grinding construction of the anchor slot D. When grinding the inclined surface of the anchor slot, adjust the angle of the fixed fixture 12 to make the wheel blade 1401 of the grinding tool 14 parallel to the inclined surface, and repeat the above operations to complete the grinding construction of the inclined surface of the anchor slot D.

[0035] Springs 9 are arranged at the upper and lower ends of the first horizontal bracket 6 and the second horizontal bracket 7 of the moving device B, which can be used for construction on a base surface with a larger curvature; when constructing on a working surface with a smaller curvature, the straight track 2 matching the curvature of the working surface can be replaced for construction.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
