Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road and bridge engineering, in particular to a road and bridge crack reinforcement structure. Background Art
[0002] With the rapid development of my country's economy and society, the scale and efficiency of the transportation industry, as the lifeline of the national economy, have been significantly improved. However, behind this vigorous development, it has also brought unprecedented challenges to infrastructure such as roads and bridges. Long-term high-intensity use and erosion of the natural environment have gradually reduced the durability and carrying capacity of transportation facilities such as roads and bridges. The most intuitive and common problem is the generation of cracks. Cracks not only affect the aesthetics of roads and bridges, but also pose a potential threat to structural safety. Therefore, timely and effective crack repair and reinforcement have become a key link in ensuring safe and smooth transportation.
[0003] Among crack reinforcement technologies, anchor reinforcement is widely used in practical projects as an economical and efficient solution. This method forms anchor holes by drilling holes at the cracks, then inserts the steel bars into the holes, and uses a special adhesive to firmly bond the steel bars to the concrete, thereby improving the overall strength and durability of the structure. However, traditional anchor reinforcement operations mostly rely on heavy hammer strikes to ensure that the steel bars reach the required insertion depth. This method is relatively simple to operate in open areas, but its limitations become apparent when faced with complex environments, such as when the crack is close to other buildings or mountains and the working space is limited.
[0004] Specifically, when the crack is located in a small space that is difficult to accommodate large construction equipment or workers cannot effectively swing a heavy hammer, manual insertion of steel bars becomes the only option. However, manual operation is not only labor-intensive, but also difficult to accurately control the insertion depth of the steel bars, which often results in insufficient insertion depth of the steel bars, thus affecting the reinforcement effect.

DETAILED DESCRIPTION
[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0025] like Figure 1-3 As shown, this embodiment provides a road bridge crack reinforcement structure, comprising:
[0026] A casing 1, wherein a cavity 11 penetrating the casing is disposed at the top of the casing, a feed inlet 12 is disposed at one end of the cavity, and a discharge outlet 13 is disposed at the other opposite end;
[0027] An impact hammer 2, which is installed on one side of the cavity near the discharge port and can slide in the cavity along the central axis of the cavity;
[0028] A clamping assembly, the clamping assembly comprises at least two petal-shaped bodies 3, the petal-shaped bodies of the clamping assembly are evenly distributed along the circumference of the cavity, one end of the petal-shaped body is hinged to the end of the impact hammer close to the feed port, and the other opposite end is inserted into the cavity;
[0029] Wherein, a force-applying device is installed in the cavity, and the force-applying device is used to drive the petal-shaped body to rotate in the cavity.
[0030] When in use, align the discharge port 13 of the housing 1 with the rebar hole, and forcefully press the housing 1 to the place where the rebar hole is required, and at the same time, insert the steel bar 5 into the cavity 11 along the feed port 12, and make one end of the steel bar 5 pass through the discharge port 13 and insert into the rebar hole. At this time, the end of the petal-shaped body 3 away from the impact hammer 2 is tightly pressed against the outer peripheral surface of the steel bar 5 to clamp the steel bar 5. The impact hammer 2 slides to the side close to the discharge port 13, and the steel bar 5 is inserted into the rebar hole under the push of the petal-shaped body 3. Then the impact hammer 2 slides to the side close to the feed port 12, and at the same time, the force-applying device drives the petal-shaped body to rotate to the side away from the steel bar 5 to loosen the steel bar. When the impact hammer 2 slides to the right side of the cavity 11, the force-applying device drives the petal-shaped body to rotate to the side close to the steel bar 5 and then clamp the steel bar, and the impact hammer 2 slides to the side close to the discharge port 13 again, and the steel bar 5 is inserted into the rebar hole under the push of the petal-shaped body 3. Repeat the above actions, and the steel bar 5 is inserted into the steel bar planting hole under the action of the impact hammer 2. A rubber layer 31 is provided on the side of the petal-shaped body 3 away from the impact hammer. This is convenient for preventing the steel bar and the petal-shaped body 3 from sliding when planting the steel bar. The utility model provides a road bridge crack reinforcement structure, which is practical for crack reinforcement work in relatively narrow spaces. The steel bar is planted through the reciprocating motion of the impact hammer, and the steel bar planting can be completed as long as the working space can accommodate the steel bar.
[0031] Optionally, a connecting rod is further included. A motor is arranged in the housing 1. A flywheel is connected to the power output end of the motor. A strip groove communicating with the cavity 11 is opened on the top of the housing 1. One end of the connecting rod is hinged to the flywheel, and the other end is inserted into the cavity 11 along the strip groove and hinged to the impact hammer. When in use, the flywheel is driven to rotate by the motor, and the impact hammer is driven to slide back and forth by the connecting rod, which is convenient for saving the physical strength of the workers.
[0032] Optionally, the material-proximal port of the housing 1 extends radially into the inner cavity to form an annular boss 14, and the side of the annular boss 14 close to the petal-shaped body extends along the axial direction of the cavity to form a tubular body 15, and an impact cavity 16 is formed between the outer wall of the tubular body 15 and the inner wall of the cavity, and the impact hammer is located in the impact cavity;
[0033] like Figure 2 As shown, a guide groove 4 is formed on one end of the inner wall of the cavity 11 near the discharge port 13, and the guide groove 4 includes an upper flat groove 41, a right transition groove 42, a lower flat groove 43 and a left transition groove 44 connected end to end. The right transition groove 42 is inclined to the lower right, and a limiting boss I421 is provided at the connection between the right transition groove and the lower flat groove 43, so that the end of the right transition groove 42 is higher than the lower flat groove 43. The left transition groove 44 is inclined to the upper right, and a limiting boss II441 is provided at the connection between the left transition groove and the upper flat groove 41, so that the end of the left transition groove is higher than the upper flat groove.
[0034] A limiting body 33 is arranged on the petal-shaped body, and the limiting body is embedded in the guide groove and can slide along the guide groove.
[0035] In the initial state, the limiting body 33 is located in the upper flat groove 41. When rebar planting is required, the rebar is inserted, and the impact hammer slides to the right. The limiting body 33 slides along the right transition groove 42 to the lower flat groove 43 to clamp the rebar. Then the impact hammer slides to the left, and the limiting body 33 slides along the lower flat groove 43 to insert the rebar into the rebar planting hole. When the limiting body 33 slides to the left end of the lower flat groove 43, the limiting body 33 slides upward along the left transition groove 44 to the upper flat groove 41, and the petal-shaped body 3 separates from the rebar to prevent the rebar from being pulled out again when the impact hammer slides to the right. The impact hammer slides to the right, and the limiting body 33 slides along the upper flat groove 41 through the right transition groove 42 to the lower flat groove 43 to clamp the rebar. Repeat the above actions until the rebar is inserted to the designed depth. In this embodiment, a limiting boss I421 is provided at the connection between the right transition groove and the lower flat groove 43, so that the end of the right transition groove 42 is higher than the lower flat groove 43, and a limiting boss II441 is provided at the connection between the left transition groove and the upper flat groove 41, so that the end of the left transition groove is higher than the upper flat groove, so as to prevent the limiter 33 from sliding in the opposite direction during the reciprocating sliding of the impact hammer. The force applying device includes a torsion spring, which is installed between the petal-shaped body and the impact hammer. Under the action of the torsion spring, the petal-shaped body maintains a tendency to rotate toward the side close to the central axis of the cavity, so as to make the limiter 33 slide to the lower flat groove 43 through the right transition groove 42.
[0036] Alternatively, if Figure 3As shown, the force-applying device also includes a spring, a blind hole 32 is formed at one end of the petal-shaped body 3 away from the impact hammer 2, one end of the limiter is slidably embedded in the blind hole, and the other opposite end is embedded in the guide groove, the spring is installed in the blind hole, and the two ends of the spring are respectively connected to the limiter and the petal-shaped body. When the limiter passes through the right transition groove 42 or the left transition groove 44, the limiter is squeezed and slides into the blind hole 32. After sliding over the limiter boss I421 or the limiter boss II441, the limiter slides to the outside of the blind hole under the action of the spring, so as to reduce the pressure on the petal-shaped body and increase the service life.
