Description

Technical Field

[0001] The utility model belongs to the technical field of bridge grouting, and in particular relates to an assembled bridge grouting device. Background Art

[0002] During the construction of highway bridge projects, the road surface is constructed in prefabricated sections. The bridge deck of the prefabricated bridge is usually made up of several prefabricated beams and slabs overlapped one by one. There are gaps between the prefabricated beams and slabs due to precision limitations. In order to make the bridge deck smoother and more beautiful after construction, it is generally necessary to pour asphalt sealant into the gaps to fill the gaps.

[0003] The existing road bridge crack grouting repair device requires continuous pushing of the repair vehicle during grouting, and then the construction personnel need to cooperate in the operation to grout the connection end. There may be some granular sand and gravel in the gap of the connection. When grouting, the sand and gravel in the gap will make the sealant and the gap not firmly bonded, resulting in an unstable connection and increasing the cost of subsequent maintenance.

[0004] To this end, we propose an assembled bridge grouting device to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-Figure 3 A prefabricated bridge caulking device comprises a bottom plate 1, a storage tank 2 for storing sealant is installed on one side of the top surface of the bottom plate 1, and a placement box 5 for placing tools is fixedly installed on the other side. Some cleaning tools or maintenance tools can be placed in the placement box 5. A rectangular frame 3 is provided on the bottom surface of the bottom plate 1. Electric push rods 4 that penetrate the bottom plate 1 and are connected to the rectangular frame 3 are installed on both sides of the top surface of the bottom plate 1 located at the storage tank 2. The rectangular frame 3 is pushed up and down by the electric push rods 4. The rectangular frame 3 is opened on both sides of the opposite sides of the rectangular frame 3. A U-shaped rod 8 is arranged in the moving groove 10. The horizontal end of the U-shaped rod 8 passes through the moving groove 10. The end of the U-shaped rod 8 away from the storage tank 2 is equipped with a cone head 7 extending into the gap of the bridge, and the end close to the storage tank 2 is provided with a flattening component for scraping the sealant. The cone head 7 can be replaced to adapt to different sizes of gaps. The surface is parallel to the bottom surface of the base plate 1, which facilitates the bottom surface of the cone head 7 to be in contact with the bottom wall of the gap. A discharge pipe 9 is installed at the bottom of the storage tank 2, which passes through the base plate 1 and is connected to the horizontal end of the U-shaped rod 8. The discharge pipe 9 is divided into two ends, two straight pipes and a folding hose. The two straight pipes are connected by a folding hose. The lower straight pipe is installed on the horizontal end of the U-shaped rod 8. The two side frames of the rectangular frame 3 that are perpendicular to the U-shaped rod 8 are provided with adjusting parts for adjusting the movement of the U-shaped rod 8. By pushing the base plate 1 to the interfaces at both ends of the bridge, the rectangular frame 3 is pushed downward by the electric push rod 4, and at the same time, the cone head 7 at one end of the U-shaped rod 8 on the rectangular frame 3 extends into the gap, and the movement of the base plate 1 pushes the cone head 7 in the gap to move, so that the granular sand and gravel in the gap can be cleaned along the inclined surface of the cone head 7, thereby improving the cleanliness of the gap, improving the connection stability of the sealant, and reducing the subsequent maintenance cost.

[0023] Reference Figure 4-Figure 5The flattening assembly includes a scraper 12, and the side wall of the scraper 12 facing the vertical end of the U-shaped rod 8 is fixedly connected with two groups of mounting blocks 13, each group of mounting blocks 13 is composed of two symmetrical mounting blocks 13, and one side of the vertical end of the U-shaped rod 8 is fixedly connected with a fixed connecting rod 14 hinged to one group of mounting blocks 13, which is hinged to a lower group of fixed blocks, and a movable connecting rod 16 is hinged on another mounting block 13 on the side of the scraper 12, and the U-shaped rod 8 above the fixed connecting rod 14 is threadedly connected to the movable connecting rod 1 6, the threaded rod 6 and the movable connecting rod 16 are rotationally connected. By tightening the bolt 15, the scraper 12 is pushed to rotate around the fixed connecting rod 14 to adjust the contact angle between the scraper 12 and the bridge surface. When the bottom of the scraper 12 contacts the bridge surface, the bolt 15 pushes the scraper 12 to rotate. The contact between the scraper 12 and the bridge surface is pushed by the bolt 15, so that the scraper 12 maintains a suitable angle, and the sealant on the bridge surface is smoothed as the base plate 1 moves.

[0024] Reference Figure 3 The adjusting member includes a threaded rod 6, which is rotatably connected to the frame of the rectangular frame 3. The threaded rod 6 passes through the frame on one side, and the other end is rotatably sleeved in the frame. The horizontal end of the U-shaped rod 8 is threadedly sleeved on the threaded rod 6. By rotating the threaded rod 6, the threaded U-shaped rod 8 is moved on the threaded rod 6 to adjust the position of the cone head 7 at one end of the U-shaped rod 8 and the bridge gap.

[0025] Reference Figure 2 Guide rods 11 are fixedly connected in the movable grooves 10 on both sides of the rectangular frame 3, and the horizontal ends of the U-shaped rod 8 are respectively slidably sleeved on the outside of the two guide rods 11. When the U-shaped rod 8 moves, the U-shaped rod 8 is located on both sides of the threaded rod 6 and is respectively slidably sleeved on the two guide rods 11, thereby improving the stability of the movement of the U-shaped rod 8.

[0026] Reference Figure 2 The side of the U-shaped rod 8 where the cone head 7 is installed is longer, and the side where the scraper 12 is installed is shorter. The cone head 7 needs to contact the bottom wall of the gap first, and the scraper 12 can adjust the contact with the bridge surface by rotating the angle.

[0027] Reference Figure 4 The side projection width of the cone head 7 is greater than the side projection width of the scraper 12. When the cone head 7 cleans the particles in the gap, the particles will be pushed away along the two sides of the cone head 7. The width of the scraper 12 is smaller than the width of the cone head 7, preventing the scraper 12 from pushing the particles into the sealant when moving.

[0028] Working principle:

[0029] First, push the device between the gaps of the bridges on both sides, and then adjust the threaded rod 6 according to the deviation distance between the gap and the U-shaped rod 8, so that the U-shaped rod 8 is located above the gap, and then push the rectangular frame 3 through the electric push rod 4, and at the same time push the U-shaped rod 8 on the rectangular frame 3 into the gap, and then according to the distance between the scraper 12 and the bridge deck, rotate the bolt 15 to make the scraper 12 rotate along the fixed connecting rod 14, so that the bottom wall of the scraper 12 contacts the bridge deck, and then move the pushing device, the cone head 7 at the front end of the U-shaped rod 8 cleans out the particles in the gap, and then the discharge pipe 9 sprays the sealant in the storage tank 2 into the gap, and the scraper 12 smoothes the sealant.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
