Description

Technical Field

[0001] This utility model relates to a torpedo canister structure. Background Technology

[0002] Torpedo canisters are concrete metering conveying devices used between mixing plants and placing booms. They transport concrete to the placing boom by traveling on specific tracks.

[0003] The torpedo canister's structure generally includes: 1. Canister shaft: used to connect the middle part of the canister to the chassis via bearings. The long end also needs to be connected to a reducer to enable the canister to rotate, usually 180 degrees; 2. Canister end caps: used at both ends of the canister, with an arc-shaped cross-section, and manufactured as a whole with the shaft and rolled steel plate through welding; 3. Rolled steel plate: made of flat steel plate, rolled into a cylindrical shape through cold bending, and manufactured as a whole with the shaft and end caps through welding.

[0004] This structure has multiple welds inside the tank, making the inner wall rough and creating many dead corners for material storage. When transporting high-grade concrete, the slump characteristics can cause residual material to remain inside the tank after unloading. After multiple operations, the residue accumulates into hard lumps that are difficult to clean. This not only leads to insufficient concrete volume but also creates safety hazards due to the shift in the tank's center of gravity. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a torpedo canister structure that effectively prevents concrete from sticking inside the canister and reduces residue inside the canister.

[0006] The technical solution adopted in this utility model is: A torpedo canister structure includes a cylindrical drum, sealing plates disposed at the openings at the left and right ends of the drum, a rotating shaft passing through the two sealing plates, and drum liners and sealing plate liners respectively covering the inner sides of the drum and the sealing plates. The drum liners and sealing plate liners are made of low surface energy materials.

[0007] Furthermore, the inner lining of the roll and the inner lining of the sealing plate are made of high-density PE board.

[0008] Furthermore, several connecting holes are provided between the drum and the drum liner, and between the sealing plate and the sealing plate liner. Bolts are inserted into the connecting holes, with their heads located inside the drum and the sealing plate, and the nuts that cooperate with them located outside the drum and the sealing plate.

[0009] Furthermore, a through hole is opened at the center of the two sealing plates on the left and right sides, the rotating shaft is mounted between the through holes of the two sealing plates, and a flange is fixedly installed on the outside of the sealing plates, with the rotating shaft fixedly connected to the flange.

[0010] Furthermore, a sleeve is fixedly installed on the flange, the rotating shaft is installed inside the sleeve, the sleeve has a through hole, and a connecting bolt is installed in the through hole.

[0011] Furthermore, a fixing hole corresponding to the through hole is provided on the rotating shaft, and the end of the connecting bolt is fitted into the fixing hole.

[0012] Furthermore, the rotating shaft includes a long shaft portion and a short shaft portion respectively fitted onto the left and right sealing plates, and a connecting sleeve disposed between the long and short shaft portions.

[0013] Furthermore, a feed port is provided on one side of the drum.

[0014] Furthermore, the sealing plate is a flat plate.

[0015] The positive effects of this utility model are: This invention features a low surface energy lining on the inner side of the roll and sealing plate, making it difficult for concrete to form a strong bond on its surface and allowing it to slide out more easily during unloading. The excellent chemical inertness, corrosion resistance, low water absorption, and good mechanical properties of the high-density PE board ensure that the lining can stably and continuously reduce residues even in harsh concrete transportation environments.

Detailed Implementation

[0017] As attached Figures 1-4 As shown, this embodiment discloses a torpedo canister structure, including a roller 1, a sealing plate 4, and a rotating shaft 2. The roller 1 is made of flat steel plate rolled into a cylindrical shape by a cold bending process. The sealing plate 4 is set on the left and right sides of the roller 1 and is manufactured into a whole with the roller steel plate by welding process. The combination of flat steel plate and reinforcing rib plate is used to ensure strength. At the same time, a discharge port 7 is provided on the side of the roller 1. The length of the discharge port 7 is the same as the length of the roller 1 to ensure that there are no dead corners inside the canister and prevent material accumulation.

[0018] A roll liner 3 and a sealing plate liner 5 are respectively installed on the inner sidewalls of the roll 1 and the sealing plate 4. They are made of low surface energy materials. In this embodiment, high-density PE board is used. Utilizing its excellent "non-stickiness" brought by its extremely low surface energy and "easy slippage" brought by its low coefficient of friction, concrete is difficult to form a firm bond on the PE surface and is easier to slide out during unloading. The effect is more obvious, especially when transporting high-grade concrete.

[0019] The inner liner of the reel 1 and the inner liner of the sealing plate 5 are installed using bolts. Specifically, several corresponding connecting holes are provided between the reel 1 and the inner liner of the reel 1, and bolts are inserted into these holes to securely connect the inner liner of the reel 1 and the reel 1. Similarly, several corresponding connecting holes are provided between the sealing plate 4 and the inner liner of the sealing plate 5, and bolts are inserted into these holes to securely connect the sealing plate 4 and the inner liner of the sealing plate 5. Preferably, the bolt heads are located on the inner side of the reel 1 and the sealing plate 4, while the nuts that mate with them are located on the outer side of the reel 1 and the sealing plate 4, preventing the bolt portion from being exposed inside the tank and causing concrete accumulation. Using bolts for installation also facilitates replacement.

[0020] Through holes are formed at the center of the two sealing plates 4. A rotating shaft 2 is installed within the corresponding through hole of the sealing plate 4. A flange 8 is fixedly installed on the outside of the sealing plate 4, and the rotating shaft 2 is fixedly connected to the flange 8. Preferably, a sleeve 13 is fixedly installed on the flange 8, and the rotating shaft 2 is placed inside the sleeve 13. A through hole is provided on the side wall of the sleeve 13, and a connecting bolt 11 is fitted into the through hole. A fixing hole 10 corresponding to the through hole is provided on the rotating shaft 2. The end of the connecting bolt 11 passes through the through hole and engages with the fixing hole 10, thereby fixing the sleeve 13 and the rotating shaft 2.

[0021] In this embodiment, the rotating shaft 2 includes a long shaft and a short shaft respectively fitted onto the left and right sealing plates 4, and a connecting sleeve 14 disposed between the long and short shafts. Using a hollow connecting sleeve to connect the long and short shafts effectively reduces weight and cost. The long and short shafts are connected to the vehicle frame via bearings. The long shaft also needs to be connected to a reducer to achieve tank rotation, typically 180 degrees. It is fixed in place using connecting bolts 11, facilitating the installation and replacement of the inner lining plates inside the tank.

[0022] This invention utilizes a flat sealing plate structure to eliminate dead angles within the tank, allowing the concrete inside to completely fall out after the tank is rotated 180 degrees. Furthermore, the addition of low surface energy linings to the drum 1 and sealing plate 4 effectively prevents concrete adhesion, avoiding the safety hazards present in existing technologies.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
