Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction, in particular to a tool for roughening a tunnel low side wall. Background Art
[0002] During tunnel construction, the roughening process of the low side walls is an important step in the construction of the water ditch cable trough. The existing construction method mainly relies on manual roughening, which not only requires a large amount of labor costs, but also has extremely low construction efficiency and a long operation time. During the manual roughening process, due to the randomness of the operation, it is easy for the roughened surface to be of different lengths and depths, making it difficult to meet the construction quality standards, and the roughening effect cannot be effectively guaranteed. In addition, the effect of manual cleaning is poor, which can easily lead to the roughened surface quality not meeting the standards, thereby affecting the subsequent construction of the water ditch cable trough and increasing the probability of quality problems such as cold joints and cracks. Therefore, there is an urgent need for a mechanized low side wall roughening device that can improve construction efficiency and ensure the quality of roughening, so as to solve the problems of low efficiency and unstable quality of manual roughening. Utility Model Content

[0005] A tool for roughening a low side wall of a tunnel comprises a mounting seat, a connecting joint is provided on the top of the mounting seat, a connecting flange is provided on the side of the connecting joint for connecting to an excavator; a plurality of hydraulic brake hammers are provided at intervals on the bottom of the mounting seat; mounting frames are installed at both ends of the mounting seat, and universal wheels are provided at the bottom of the mounting frames.
[0006] As a further solution of the present invention: a vertically arranged mounting rod is installed on the top of the mounting frame, and one end of the mounting rod extending to the bottom of the mounting frame is sleeved with a mounting plate, and the universal wheel is installed at the bottom of the mounting plate.
[0007] As a further solution of the present invention: a decompression spring is provided between the top of the mounting plate and the bottom of the mounting bracket, and the decompression spring is sleeved on the outside of the mounting rod.
[0008] The beneficial effects of the utility model are:
[0009] 1. Improve construction efficiency: By connecting with the excavator, mechanized operation is realized, replacing traditional manual roughing, greatly improving the efficiency of roughing the low side walls of the tunnel and reducing construction time.
[0010] 2. Save labor costs: Using mechanized equipment instead of manual operation reduces dependence on manpower, saves a lot of labor costs, and reduces the labor intensity of construction workers.
[0011] 3. Ensure the chiseling effect: The hydraulic brake hammer can accurately control the chiseling force and depth to ensure that the chiseled surface is uniform, avoid the unevenness caused by manual operation, and significantly improve the construction quality.
[0012] 4. Reduce later quality problems: By improving the quality of chiseling, the probability of quality problems such as cold joints and cracks caused by uneven chiseling during the construction of the ditch cable trough is effectively reduced, thereby improving the overall durability of the project.
[0013] 5. Significant economic benefits: Mechanized operations not only shorten the construction period, but also improve the quality of construction work, reduce the probability of rework and repair, and bring significant economic benefits and competitive advantages to the construction party.

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0018] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0019] Reference Figure 1-2 A tool for roughening the low side wall of a tunnel includes a mounting base 1, a connecting joint 8 is provided on the top of the mounting base 1, and a connecting flange 9 is provided on the side of the connecting joint 8 for connecting to an excavator; a plurality of hydraulic brake hammers 2 are provided at intervals at the bottom of the mounting base 1; mounting frames 3 are installed at both ends of the mounting base 1, and a universal wheel 4 is provided at the bottom of the mounting frame 3.
[0020] When in use, the top end of the connecting joint 8 is connected to the excavator through the connecting flange 9 and the connecting pin, realizing mechanized construction operations, saving a lot of manpower and operation time, and greatly improving the construction efficiency of low side wall roughening. The hydraulic brake hammer 2 can realize the low side wall roughening function, ensure the roughening effect, improve the construction quality of the ditch cable trough, and effectively reduce the probability of quality problems occurring in the ditch cable trough, bringing significant economic benefits.
[0021] As a preferred embodiment of the present invention, a vertically arranged mounting rod 7 is installed on the top of the mounting frame 3, and one end of the mounting rod 7 extending to the bottom of the mounting frame 3 is sleeved with a mounting plate 5, and the universal wheel 4 is installed at the bottom of the mounting plate 5.
