Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a concrete spray head scraper for tunnel construction. Background Art

[0002] After the grouting work in the tunnel is completed, the bulges at the grouting position need to be scraped flat. Usually, the staff deal with the bulges by smoothing them with a shovel. Since the position to be smoothed is not fixed, the staff need to change positions back and forth to deal with the bulges, which brings inconvenience to the staff's work. At the same time, manual smoothing requires a lot of manpower and time, which reduces the work progress.

[0003] The existing concrete spray head scraper, such as the concrete spray head scraper disclosed in the publication (announcement) number: CN215408674U, needs to adjust the position of the concrete spray head back and forth when scraping the concrete bulge position because the scraper is parallel to the spray head. At the same time, the vibration generated during the scraping will be directly transmitted to the concrete spray head, which can easily cause the parts on the concrete spray head to loosen. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a concrete sprinkler scraper for tunnel construction. The utility model installs the concrete sprinkler scraper for tunnel construction on the concrete spraying head through a mounting mechanism. The buffer spring on the mounting mechanism can increase the deflection of the sprinkler head to prevent misoperation from damaging other parts of the sprinkler head. At the same time, the scraper can be appropriately rotated according to the situation of the bulge, so as to facilitate the scraping of the bulge position of the concrete.

[0005] In order to achieve the purpose of the utility model, the utility model adopts the following technical solutions:

[0006] A concrete spray head scraper for tunnel construction comprises a mounting mechanism, wherein the scraper is mounted on a positioning end of the mounting mechanism.

[0007] Two connecting plates are arranged on one side of the scraper close to the mounting mechanism, and the scraper is connected to the positioning end of the mounting mechanism through the connecting plates.

[0008] The mounting mechanism includes a first sleeve, a buffer spring, a second sleeve, a connecting rod, a connecting ring and a rotating rod. One end of the first sleeve is connected to the second sleeve through a buffer spring, and connecting rods are fixedly connected on both sides of the second sleeve. One end of the connecting rod is fixedly connected to a connecting ring, and a rotating rod is rotatably connected inside the connecting ring. The rotating rod is fixedly connected to a connecting plate on the scraper.

[0009] The connecting rod is an L-shaped rod.

[0010] Two limit plates are fixedly connected to the connecting ring, and the connecting plate on the scraper is located between the two limit plates.

[0011] The limiting plate is provided with a sliding groove, and the position of the sliding groove corresponds to the position of the connecting plate on the scraper.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] The utility model discloses a concrete spray head scraper for tunnel construction, which is installed on a concrete spraying head through an installation mechanism. The deflection of the spray head can be increased by a buffer spring on the installation mechanism to prevent other parts on the spray head from being damaged by misoperation. At the same time, the scraper can be properly rotated according to the situation of the bulge, so as to facilitate the scraping of the bulge position of the concrete.

[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Combined with Figures 1 to 3 The concrete spray head scraper for tunnel construction comprises a mounting mechanism 1, and a scraper 2 is mounted on the positioning end of the mounting mechanism 1.

[0020] Two connecting plates are provided on one side of the scraper 2 close to the mounting mechanism 1 , and the scraper 2 is connected to the positioning end of the mounting mechanism 1 through the connecting plates.

[0021] The mounting mechanism 1 includes a first sleeve 101, a buffer spring 102, a second sleeve 103, a connecting rod 104, a connecting ring 105 and a rotating rod 106. One end of the first sleeve 101 is connected to the second sleeve 103 through the buffer spring 102, and the two sides of the second sleeve 103 are respectively fixedly connected with the connecting rod 104, one end of the connecting rod 104 is fixedly connected with the connecting ring 105, and the connecting ring 105 is rotatably connected with the rotating rod 106, and the rotating rod 106 is fixedly connected to the connecting plate on the scraper 2. The first sleeve 101, the buffer spring 102 and the second sleeve 103 are all sleeved on the concrete spraying head.

[0022] The connecting rod 104 is an L-shaped rod.

[0023] The connection ring 105 is fixedly connected to two limit plates 3 , and the connection plate on the scraper 2 is located between the two limit plates 3 .

[0024] The limit plate 3 is provided with a sliding groove, and the position of the sliding groove corresponds to the position of the connecting plate on the scraper 2. The rotation angle of the scraper 2 is adjusted by the limit plate 3 to avoid the scraper 2 rotating too much and affecting the concrete leveling effect.

[0025] When the concrete spray head scraper for tunnel construction is in use, the staff puts the first sleeve 101, the buffer spring 102 and the second sleeve 103 on the concrete spray head, so that the scraper 2 moves with the concrete spray head. When the scraper 2 is working, the scraper 2 will swing up and down with the movement of the concrete spray head. The swing angle of the scraper 2 is limited by the limit plate 3, which is convenient for scraping the bulge position of the concrete flat. At the same time, the vibration generated when the bulge is flattened is buffered by the buffer spring 102.

[0026] The parts of the present invention that are not described in detail are prior art. Although the present invention is specifically demonstrated and introduced in conjunction with the preferred implementation scheme, there are many methods and ways to implement the technical solution. The above is only a preferred implementation scheme of the present invention. However, technical personnel in the relevant field should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined in the attached claims, which are all within the scope of protection of the present invention.
