Description

Technical Field

[0001] This utility model relates to the field of core mold vibration pipe making machine technology, and in particular to a rebar mesh correction device for a core mold vibration pipe making machine. Background Technology

[0002] The core mold vibration pipe making machine is a core piece of equipment in modern concrete pipe production. With its efficient and precise pipe making process, it is widely used in various infrastructure construction projects, providing a solid guarantee for the construction of urban pipe networks, water conservancy projects and other transportation systems.

[0003] The core mold vibration pipe making machine includes a cylindrical inner mold, with an annular base fitted at the bottom of the inner mold. An annular outer mold is detachably connected to the base. The outer mold is coaxial with the inner mold, and the inner diameter of the outer mold is larger than the diameter of the inner mold. A steel mesh is placed between the inner mold and the outer mold. When making concrete pipes, workers use a concrete placing machine to pour concrete between the inner mold and the outer mold.

[0004] However, during the concrete pouring process, the reinforcing mesh may be close to the outer wall of the inner mold or the inner wall of the outer mold, and may be offset. In this case, the concrete pipe is prone to uneven distribution of the reinforcing mesh or even exposure, which affects the structure of the concrete pipe and thus the product quality of the concrete pipe. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the misalignment of the reinforcing mesh affects the product quality of pipelines, and to propose a reinforcing mesh correction device for a core mold vibration pipe making machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a rebar mesh correction device for a core mold vibration pipe making machine, including an outer mold, a base at the bottom of the outer mold, the base being sleeved on the outer side of the lower end of the inner mold, a rebar mesh being arranged between the outer mold and the inner mold, a sleeve ring being snapped on the upper end of the outer mold, a fixing seat being sleeved on the upper surface of the sleeve ring, the fixing seat being fixedly connected to the sleeve ring by a first bolt, the end of the first bolt passing through the sleeve ring and being fixedly connected to the outer mold, and a pair of locking rods being provided on the surface of the fixing seat, the pair of locking rods being sleeved on the inner and outer sides of the rebar mesh respectively.

[0008] Preferably, the central axis of the base coincides with the central axis of the outer mold, and the central axis of the outer mold coincides with the central axis of the inner mold.

[0009] Preferably, the upper surface of the base is provided with a locking groove, and the lower end of the steel mesh is fitted into the locking groove.

[0010] Preferably, the fixing base is provided with multiple bases arranged in a circular array around the sleeve ring, and the central axis of the sleeve ring coincides with the central axis of the outer mold.

[0011] Preferably, the upper surface of the fixing seat is provided with grooves, and the inside of the fixing seat is provided with sliding grooves. The two sides of the sliding grooves are connected to the inside of the grooves. A slider is slidably provided inside the sliding grooves. The upper and lower ends of the sliders extend into the grooves on the upper and lower sides respectively and are fixedly installed with limit blocks. A second bolt is movably inserted through the end of the upper limit block. A mating hole is provided on the bottom wall of the upper groove. The lower end of the second bolt is threadedly connected to the inside of the mating hole. The lower surface of the lower limit block is fixedly connected to the locking rod.

[0012] Preferably, the mating holes are provided in multiple ways and are evenly distributed along the length of the slide groove, and the extension line of the slide groove along the length of the slide groove passes through the central axis of the sleeve ring.

[0013] Preferably, the length direction of the locking rod is parallel to the central axis of the sleeve ring.

[0014] Preferably, the pair of locking rods are in the same vertical plane, which passes through the central axis of the collar.

[0015] This utility model proposes a rebar mesh correction device for a core mold vibration pipe-making machine. The beneficial effects are as follows: During use, the base supports the inner and outer molds, and the locking groove at the lower end of the rebar mesh ensures precise radial centering of the bottom of the mesh. The upper fixing structure, consisting of a connecting ring, a fixing seat, and a first bolt, works in conjunction with the locking rod to engage the inner and outer sides of the upper end of the rebar mesh, further ensuring accurate radial positioning at the top. This dual positioning mechanism effectively prevents the rebar mesh from shifting during pipe-making, ensuring balanced stress on all parts of the pipe body, significantly enhancing the connection strength of the rebar at the joints, thereby improving the overall structural stability and service life of the pipe and providing reliable assurance for pipe production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-5 A rebar mesh correction device for a core mold vibration pipe-making machine includes an outer mold 1. A base 4 is provided at the bottom of the outer mold 1, and the base 4 is fitted onto the outer side of the lower end of an inner mold 2. The central axis of the base 4 coincides with the central axis of the outer mold 1, and the central axis of the outer mold 1 coincides with the central axis of the inner mold 2. The base 4 supports both the outer mold 1 and the inner mold 2. A rebar mesh 3 is provided between the outer mold 1 and the inner mold 2. The rebar mesh 3 serves as the skeleton of the cement pipe, bearing the load of the pipe body. A locking groove 15 is provided on the upper surface of the base 4. The lower end of the rebar mesh 3 fits into the locking groove 15, which supports the lower end of the rebar mesh 3, ensuring that the bottom of the rebar mesh 3 is positioned between the inner mold 2 and the outer mold 1.

[0024] The upper end of the outer mold 1 is fitted with a sleeve ring 5, and a fixing seat 7 is fitted on the upper surface of the sleeve ring 5. Multiple fixing seats 7 are arranged in a circumferential array around the sleeve ring 5. The fixing seat 7 is fixedly connected to the sleeve ring 5 by a first bolt 6. The end of the first bolt 6 passes through the sleeve ring 5 and is fixedly connected to the outer mold 1. The first bolt 6 can fix the outer mold 1, the sleeve ring 5 and the fixing seat 7 together, and the central axis of the sleeve ring 5 coincides with the central axis of the outer mold 1.

[0025] A pair of locking rods 14 are provided on the surface of the fixing base 7. The pair of locking rods 14 are respectively sleeved on the inner and outer sides of the reinforcing mesh 3. In this embodiment, the locking rods 14 are fixedly connected to the fixing base 7. The lower end of one locking rod 14 extends into the gap between the reinforcing mesh 3 and the outer mold 1, and the lower end of the other locking rod 14 extends into the gap between the reinforcing mesh 3 and the inner mold 2. The two locking rods 14 can restrict the position of the upper end of the reinforcing mesh 3. Furthermore, since the lower end of the reinforcing mesh 3 is restricted by the locking groove 15, the radial position of the reinforcing mesh 3 in the mold can be kept centered (maintaining a uniform distance from the inner and outer molds), avoiding uneven wall thickness of the tube body and excessively thin or thick local reinforcing bar protective layer due to displacement.

[0026] Working principle: When using the rebar mesh correction device of the core mold vibration pipe making machine, the base 4 supports the outer mold 1 and the inner mold 2. The lower end of the rebar mesh 3 is placed in the locking groove 15 to keep the radial position of the bottom of the rebar mesh 3 centered. The sleeve ring 5 is sleeved on the outer side of the upper end of the outer mold 1. The fixing seat 7 is snapped on the outer side of the sleeve ring 5 and fixed by the first bolt 6. The lower end of the locking rod 14 is snapped on the inner and outer sides of the upper end of the rebar mesh 3 to keep the radial position of the top of the rebar mesh 3 centered, so that the rebar mesh 3 as a whole will not shift. This can ensure that the force on each part of the pipe is balanced and improve the connection strength of the rebar at the interface.

[0027] Example 2: In Example 1, because the gap sizes of different molds are different, when the gap between the outer mold 1 and the inner mold 2 is too large or too small, and the position of the locking rod 14 cannot change, the spacing between the reinforcing mesh and the outer mold 1 and the inner mold 2 will be different. The offset of the reinforcing mesh 3 will lead to uneven stress on various parts, thereby affecting the connection strength of the reinforcing bars. Therefore, this example is proposed. (Refer to...) Figure 1-5 In another preferred embodiment of this utility model, based on embodiment 1, the upper surface of the fixing base 7 is provided with grooves 8, and the interior of the fixing base 7 is provided with sliding grooves 9. The two sides of the sliding grooves 9 are connected to the interior of the grooves 8. A slider 11 is slidably mounted inside the sliding grooves 9. The upper and lower ends of the slider 11 extend into the grooves 8 on the upper and lower sides respectively and are fixedly installed with limiting blocks 10. The slider 11 and the limiting blocks 10 can move, thereby adjusting the position of the locking rod 14. A second bolt 12 is movably inserted through the end of the upper limiting block 10. A mating hole 13 is provided on the bottom wall of the upper groove 8. The lower end of the second bolt 12 is threadedly connected to the interior of the mating hole 13. Multiple mating holes 13 are provided and evenly distributed along the length of the sliding groove 9. The second bolt 12 can mate with the mating holes 13 at different positions, allowing the locking rod 14 to be fixed in different positions. The extension line of the slide groove 9 in the length direction passes through the central axis of the sleeve ring 5. The lower surface of the lower limit block 10 is fixedly connected to the locking rod 14. The length direction of the locking rod 14 is parallel to the central axis of the sleeve ring 5. A pair of locking rods 14 are in the same vertical plane, which passes through the central axis of the sleeve ring 5.

[0028] When the position of the locking rod 14 needs to be adjusted, rotate the second bolt 12 to disengage it from the mating hole 13, then move the limiting block 10 and the slider 11 to move the locking rod 14 to the desired position, ensuring that the upper end of the reinforcing mesh 3 is radially centered. Then rotate the second bolt 12 to engage with the threaded mating hole 13. The position of the locking rod 14 can be adjusted according to the gap between the inner mold 2 and the outer mold 1 to ensure that the reinforcing mesh 3 can be fixed in the middle of the gap.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
