Description

Technical Field

[0001] The utility model relates to the technical field of track plate forming devices, in particular to a combined track plate grouting hole cone barrel. Background Art

[0002] In the processing of prestressed track slabs, the cone barrel is used to form grouting holes and assist demoulding. After the track slab is prefabricated, a demoulding device is required to separate the track slab and the cone barrel from the track slab mold, and then peel the cone barrel from the track slab. The Chinese utility model patent with patent number CN209633351U discloses a track slab demoulding machine, in which the top of the grouting boss has a boss arranged in an inverted T shape. After the track slab is prefabricated, the grouting boss can be removed from the track slab mold together with it. In actual use, the inventor found that: if the grouting boss and the boss are processed by an integrated molding method, more materials are required as a whole; if a screw is used to connect a single grouting boss and a boss, when the track plate is demolded from the track plate mold by lifting the boss, since the track plate is relatively heavy, the screw needs to bear a large force. In order to ensure the overall stability, several screws need to be used, and then a single grouting boss needs to be drilled and tapped for a long time; if the grouting boss and the boss are fixed by welding, welding rods and welding processes need to be used according to the materials of the grouting boss and the boss to ensure the welding quality, and it is also time-consuming and labor-intensive when welding in large quantities. There is an urgent need for a combined track plate grouting hole cone barrel that can be easily disassembled and assembled, saves processing materials, and ensures the connection strength during lifting. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a combined track plate grouting hole cone barrel which can be conveniently disassembled and assembled, saves processing materials and ensures connection strength during lifting.

[0004] To solve the above technical problems, the utility model includes a barrel body, the outer surface of the barrel body is a conical surface whose diameter gradually decreases from bottom to top, the barrel body is provided with a first avoidance hole extending upward from the bottom of the barrel body, the barrel body is provided with a second avoidance hole that passes through the top of the barrel body to the first avoidance hole, the diameter of the first avoidance hole is larger than the diameter of the second avoidance hole, the barrel body is provided with a connecting seat located in the first avoidance hole and the second avoidance hole, the connecting seat includes a base located in the first avoidance hole, a seat body located in the second avoidance hole is provided on the top of the base, the outer diameter of the base is equal to the diameter of the first avoidance hole, the outer diameter of the seat body is equal to the diameter of the second avoidance hole, a clamping protrusion with a T-shaped cross-section is provided on the top of the seat body, the maximum outer diameter of the clamping protrusion is less than or equal to the diameter of the second avoidance hole, a screw is passed through the clamping protrusion, the bottom of the screw is located below the bottom of the barrel body, the base and the seat body are integrally formed, and the clamping protrusion and the connecting seat are integrally formed.

[0005] After adopting the above structure, the connecting seat and the clamping protrusion can be assembled to the barrel body by hammering and chiseling, and can also be removed from the barrel body by hammering and chiseling, so that they can be easily disassembled and assembled. After the connecting seat and the clamping protrusion are assembled to the barrel body, the top of the base is firmly against the step surface formed by the first avoidance hole and the second avoidance hole. During lifting, since the base and the seat body are integrally formed and the clamping protrusion and the connecting seat are integrally formed, the connecting seat and the clamping protrusion are subjected to force as a whole, ensuring the connection strength with the barrel body during lifting. Since the maximum outer diameter of the clamping protrusion is less than or equal to the diameter of the second avoidance hole, when disassembling and assembling the connecting seat and the clamping protrusion to the barrel body, the barrel body can avoid the clamping protrusion. During processing, the barrel body, the connecting seat and the clamping protrusion can be processed separately, which can effectively utilize material resources, not only saving processing materials but also saving processing time relative to overall processing.

[0006] Furthermore, the clamping protrusion includes a connecting portion connected to the seat body, and a top cover portion with a minimum outer diameter larger than the outer diameter of the connecting portion is provided on the top of the connecting portion.

[0007] Furthermore, the outer diameter of the top cover portion is equal to the diameter of the second avoidance hole, and the upper and lower outer edges of the top cover portion are provided with first chamfers.

[0008] Furthermore, the top outer edge of the seat body has a second chamfer.

[0009] Furthermore, a third chamfer is provided on the top edge of the second avoidance hole.

[0010] Furthermore, a sealing installation groove surrounding the conical surface is provided at the bottom of the barrel body, and a sealing ring with a bottom located below the bottom of the barrel body is provided in the sealing installation groove.

[0011] By setting the connecting portion and the top cover portion, a clamping protrusion with a T-shaped cross section can be formed, and the structural strength is excellent; by setting the first chamfer, when the clamping protrusion is assembled upwardly to the barrel body and removed downwardly from the barrel body, the first chamfer plays a guiding role, preventing the occurrence of extrusion burrs in the second avoidance hole due to the skew of the top cover portion, so that the hammering and chiseling operations are smooth and efficient; by setting the second chamfer, when the connecting seat and the clamping protrusion are assembled upwardly into the second avoidance hole of the barrel body, the second chamfer can play a guiding role in the installation direction of the seat body, preventing the occurrence of extrusion burrs in the second avoidance hole due to the skew of the seat body, so that the hammering and chiseling operations are smooth and efficient; by setting the third chamfer, when the connecting seat and the clamping protrusion are disassembled downwardly, the third chamfer can cooperate with the first chamfer of the lower edge of the top cover portion to guide the disassembly direction of the top cover portion, preventing the occurrence of extrusion burrs in the second avoidance hole due to the skew of the top cover portion, so that the hammering and chiseling operations are smooth and efficient. By providing the sealing installation groove and the sealing ring, after the utility model is installed on the track plate mold by screws, the sealing ring plays a sealing role through deformation, effectively isolating the inside and outside of the barrel body, and ensuring the cleanliness of the inside of the barrel body. In summary, the utility model has the advantages of reasonable structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

The barrel body 1 is provided with a connecting seat 2 located in the first avoidance hole 12 and the second avoidance hole 13, and the connecting seat 2 includes a base 21 located in the first avoidance hole 12, and a seat body 22 located in the second avoidance hole 13 is provided on the top of the base 21. The outer edge of the top of the seat body 22 has a second chamfer 221. The outer diameter of the base 21 is equal to the diameter of the first avoidance hole 12, and the outer diameter of the seat body 22 is equal to the diameter of the second avoidance hole 13. The top of the seat body 22 is provided with a clamping protrusion 3 with a T-shaped cross section, and the maximum outer diameter of the clamping protrusion 3 is less than or equal to the diameter of the second avoidance hole 13. Specifically, the clamping protrusion 3 includes a connecting portion 31 connected to the seat body 22, and a top cover portion 32 with a minimum outer diameter greater than the outer diameter of the connecting portion 31 is provided on the top of the connecting portion 31. The connecting portion 31 and the top cover portion 32 form a groove structure for being held by the clamping claw. When clamping, the clamping claw can clamp the connecting portion 31 of the clamping protrusion 3 in a gripping posture, or clamp the top cover portion 32 of the clamping protrusion 3 in a covering posture from top to bottom. Optionally, the outer diameter of the top cover portion 32 is equal to the diameter of the second avoidance hole 13, and the upper and lower outer edges of the top cover portion 32 are provided with a first chamfer 321.
