Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, to a tunnel sidewall roughening construction device. Background Technology

[0002] Roughening the sidewalls of tunnels is a crucial step in tunnel construction. Performed within the enclosed tunnel environment, the technical skill and quality of this process directly impact the overall quality and safety of the tunnel project. In recent years, mechanized and automated equipment, such as electric rock drills and pneumatic hammers, has been primarily used for roughening sidewalls. These devices offer advantages such as high efficiency, precision, and safety, significantly improving construction efficiency and project quality. However, some challenges remain.

[0003] For example, pneumatic hammers and handheld chisels, although small in size and light in weight and capable of handheld chiseling, have a limited number of chisel heads, resulting in low efficiency, and rely heavily on the operator's experience.

[0004] Large mechanical shaving machines, on the one hand, occupy a large area, affecting other construction work; on the other hand, the equipment is relatively expensive, resulting in high construction costs.

[0005] In addition, the low side walls have a certain height and a certain curvature contour structure, which brings great trouble to the conventional chiseling machine modification design. Utility Model Content

[0006] This invention addresses the problems existing in the roughening of low sidewalls using existing roughening machines by providing a roughening device for tunnel low sidewalls. This device can adapt to the special contour structure of low sidewalls, enabling rapid roughening, and the roughening equipment is simple and easy to operate.

[0007] This utility model is achieved through the following technical solution:

[0008] A tunnel sidewall roughening construction device includes a frame and a roughening machine body. The frame is provided with at least two guide rails that are consistent with the outer contour of the tunnel sidewall. The roughening machine body is connected to a guide wheel shaft assembly and slides along the guide rails through the guide wheel shaft assembly.

[0009] The frame is also equipped with a first traction mechanism and a second traction mechanism. The first traction mechanism is connected to the upper part of the chipping machine body and is used to pull the chipping machine body to slide along the guide rail. The second traction mechanism is connected to the lower part of the chipping machine body and is used to pull the chipping machine body to abut against the frame.

[0010] The main body of the chiseling machine includes several chiseling heads arranged in a straight line.

[0011] Optionally, both the first traction mechanism and the second traction mechanism are winches.

[0012] Optionally, the guide wheel shaft assembly includes a rotating shaft with guide wheels at both ends, the guide wheels being distributed and embedded in the guide rail portion.

[0013] Optionally, the rotating shaft is located on the upper side of the main body of the shaving machine.

[0014] Optionally, the frame includes two support plates that can be detachably connected to the frame body, the guide rail is disposed on the support plates, and the second traction mechanism pulls the shaving machine body to abut against the support plates;

[0015] The side of the support plate that abuts against the main body of the chisel has the same outline as the outer contour of the tunnel's low sidewall.

[0016] Optionally, a pad and rubber components are also provided between the main body of the shaving machine and the support plate.

[0017] Optionally, the frame is provided with a slot assembly, and the support plate can be inserted between the slot assemblies and fixed by a pin.

[0018] The technical solution of this utility model has at least the following beneficial effects:

[0019] The tunnel sidewall roughening construction device of this utility model, by setting a guide rail part that is consistent with the outer contour of the tunnel sidewall, allows the roughening machine body to move along the guide rail part, thereby always keeping the roughening head at a suitable and uniform distance along the contour of the sidewall. The first traction mechanism can move the roughening machine body along the height direction to overcome gravity and complete the roughening work, while the second traction mechanism can hold the roughening machine body against the frame during the roughening process to achieve positioning and maintain its stability.

[0025] Reference Figures 1-3 The tunnel low sidewall roughening construction device of this utility model includes a frame 10 and a roughening machine body 20. The frame 10 adopts a manually pushable frame 10 structure, which is simpler in structure and lower in cost compared with the tracked roughening machine.

[0026] The frame 10 has at least two guide rail sections 121 that conform to the outer contour of the tunnel's low sidewall. A guide wheel shaft assembly 50 is connected to the main body 20 of the scabbing machine, and the main body 20 of the scabbing machine slides along the guide rail sections 121 via the guide wheel shaft assembly 50. The guide rail sections 121 can be fixedly arranged on the frame 10, or they can be arranged through a detachable structure. Specifically, the frame 10 includes two support plates 12 that can be detachably connected to the main body of the frame 10, and the guide rail sections 121 are set on the support plates 12. By using detachable support plates 12 to arrange the guide rail sections 121, the support plates 12 can be replaced according to the low sidewall structure of different tunnels, thereby improving the versatility of the equipment.

[0027] The support plate 12 is disassembled by using a slot assembly 13 on the frame 10. The support plate 12 can be inserted between the sliding groove assemblies and secured with a pin. In this embodiment, four slots are provided on the frame 10. Two slots in the vertical direction form a set of slot assemblies 13. The four slots can accommodate two support plates 12. A guide rail portion 121 is arranged on the inner side of the support plate 12, allowing the guide wheel shaft assembly 50 to slide between the guide rail portions 121 of the two support plates 12. The two ends of the support plate 12 are provided with structures that match the slots. It is inserted into the slot from the end of the slot and locked with a pin. For low side walls with different contours, the pin is removed and the support plate 12 is replaced.

[0028] The guide wheel shaft assembly 50 includes a rotating shaft with guide wheels at both ends. The guide wheels are embedded in the guide rail section 121, and the rotating shaft is located on the upper side of the shaving machine body 20. The outer diameter of the guide wheels is approximately equal to the width of the guide rail section 121. For example, bearings or other wheels can be used to embed in the guide rail section 121 and guide the shaving machine body 20 according to the trajectory of the guide rail section 121. Since the outline of the guide rail section 121 is consistent with the outline of the low side wall, the distance between the guide rail section 121 and the low side wall can be kept consistent. This ensures that the shaving head 21 of the shaving machine can always maintain a suitable position for shaving during the shaving process, and maintains consistency during the lifting and lowering process, without relying too much on the operator's operating experience.

[0029] The main body 20 of the chiseling machine in this embodiment adopts the structural design of a conventional pneumatic chiseling machine, including a number of chiseling heads 21 arrayed along a straight line. Preferably, a single row of chiseling heads 21 arranged horizontally is sufficient, and no more than two rows are required. This is because the contour of the low sidewall has a certain curvature, and a larger number of chiseling heads 21 would actually lead to a decrease in chiseling quality. Using a single row of chiseling heads 21 arranged horizontally can compensate for the numerical disadvantage through upward movement, and is also more efficient than a handheld chiseling machine.

[0030] In this embodiment, the frame 10 is also equipped with a first traction mechanism 40 and a second traction mechanism 30. The first traction mechanism 40 is connected to the upper part of the chisel body 20 and is used to pull the chisel body 20 to slide along the guide rail 121. The second traction mechanism 30 is connected to the lower part of the chisel body 20 and is used to pull the chisel body 20 to abut against the frame 10. The second traction mechanism 30 pulls the chisel body 20 to abut against the support plate 12. Both the first traction mechanism 40 and the second traction mechanism 30 are winches. During construction, the chisel position of the chisel body 20 is first adjusted by raising and lowering the first traction mechanism 40. Once the position is determined, the chisel machine can be pulled and positioned on the frame 10 by the traction of the second traction mechanism 30, avoiding vibration during chiseling and thus preventing instability of the chisel machine.

[0031] The second traction mechanism 30 can abut against the support plate 12 to maintain stability. To avoid vibration transmission and noise, a pad 70 and a rubber component 60 are also provided between the chipper body 20 and the support plate 12. The pad 70 can be used to adjust the fine-tuning distance to keep the chipping head 21 of the chipper body 20 in the proper position with the low side wall, while the rubber component 60 is used for shock absorption. During installation, the rubber component 60 and the pad 70 are fixed to the chipper body 20 with bolts.

[0032] The side of the support plate 12 that abuts against the main body 20 of the chisel has the same outline as the outer contour of the tunnel sidewall, which can better keep the chisel head 21 of the main body 20 of the chisel from the sidewall in the right position.
