Description

Technical Field

[0001] This utility model relates to the field of shaft excavation technology, and in particular to a shaft drum structure. Background Technology

[0002] Shaft boring machines (TBMs) are specialized equipment for vertical shaft construction, adaptable to engineering projects in land, river, and marine environments. The product integrates functions such as tunneling, support, muck removal, shaft wall assembly, and muck separation, enabling simultaneous multi-process construction. The equipment features a modular and streamlined design, facilitating disassembly, assembly, and transportation. It incorporates dynamic sensing technology, boasting a high degree of intelligence and mechanization, allowing for unmanned underground operations. TBMs are characterized by safety, high efficiency, low cost, ease of maintenance, and convenient relocation. They can meet the needs of kilometer-level vertical shaft construction, providing new equipment and methods for mining, marine engineering, water conservancy, and new energy projects. They offer powerful tunneling tools for deep-earth engineering, underground parking lots, and underground space development. The shaft drum, a crucial component of the TBM, acts like the machine's teeth; its quality directly impacts the construction speed and progress of the entire project.

[0003] After the equipment is started, the hydraulic motor, acting as the drive mechanism, transmits power stably to the connecting plate via bolts. Since the connecting plate is securely welded to the cylinder, the cylinder also begins to rotate at high speed, thus performing well rotation.

[0004] In existing technologies, some vertical shaft drum structures result in the scattered distribution of crushed materials during use, making it difficult for the equipment's built-in material collection components to collect them efficiently. This leads to the material collection components needing to spend more time and effort to find and grab the materials, significantly reducing the discharge efficiency. Therefore, to address these shortcomings, a new vertical shaft drum structure is proposed to solve the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vertical shaft drum structure, which aims to improve the problem that some existing vertical shaft drum structures require manual collection of materials during use, resulting in reduced work efficiency.

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

[0007] A vertical shaft drum structure includes a cylinder, a connecting plate, a reinforcing plate, and a sealing ring. A cylindrical cutter holder is welded inside the cylinder through a groove. An annular groove is formed inside the cylindrical cutter holder. A retaining ring is fixedly connected inside the cylindrical cutter holder. A shaft is fixedly connected inside the retaining ring. A tapered cutting tooth is fixedly connected outside the shaft. A cylindrical tensioning ring is slidably connected outside the tapered cutting tooth. The connecting plate is fixed to the cylinder by welding.

[0008] As a further description of the above technical solution:

[0009] The outer diameter of the cylinder is a portion of an ellipse, and the working trajectory surface of the tapered cutting tooth is similar to the shape of the outer contour.

[0010] As a further description of the above technical solution:

[0011] The grooves on the outer arc surface of the cylinder are arranged at equal intervals, and the cylindrical knife holder is slidably connected to the inside of the grooves.

[0012] As a further description of the above technical solution:

[0013] The head of the tapered cutting tooth and the outside of the large disc are welded with high-chromium wear-resistant welding wire, and the inside of the cylindrical tensioning ring is slidably connected to the outside of the cylindrical tool holder.

[0014] As a further description of the above technical solution:

[0015] A hydraulic motor is fixedly connected to the inside of the connecting plate by bolts, and the inner wall of the cylinder is fixedly connected to the outer wall of the reinforcing plate.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, conical cutting teeth arranged according to rules on the outside of the drum achieve uniform cutting of the excavation surface through the running trajectory of the conical cutting teeth, thereby crushing the material. The drum's external structure and the arrangement of the conical cutting teeth also help to gather and collect the material. The crushed material is then discharged using the equipment's built-in material receiving component, thus improving work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a vertical shaft drum structure, including a cylinder 1, a connecting plate 2, a reinforcing plate 3, and a sealing ring 4. A hydraulic motor is bolted to the inside of the connecting plate 2 for power transmission. The inner wall of the cylinder 1 is fixedly connected to the outer wall of the reinforcing plate 3, preventing deformation or damage to the cylinder 1 under complex external forces and extending the service life of the equipment. A cylindrical cutter holder 5 is welded to the inside of the cylinder 1 through grooves, allowing the cylindrical cutter holder 5 to fit into the grooves for easy welding and fixing. The grooves on the outer arc surface of the cylinder 1 are arranged at equal intervals. This external shape and the arrangement of the cutting teeth allow the crushed material to converge towards the center, facilitating the material collection device located in the middle of the equipment to suck up and deliver the material. The cylindrical cutter holder 5 is slidably connected to the inside of the grooves, further facilitating welding and fixing.

[0025] The cylindrical cutter holder 5 has an internal annular groove, and a retaining ring is fixedly connected inside the cylindrical cutter holder 5. The retaining ring fits into the annular groove for locking and fixing. A shaft is fixedly connected inside the retaining ring, and the connection is improved by welding. A tapered cutting tooth 6 is fixedly connected externally to the shaft. The head of the tapered cutting tooth 6 and the exterior of the large disc are welded with high-chromium wear-resistant welding wire. The drum-shaped design provides centering during operation, which is beneficial to the stability of excavation and the equipment. The outer diameter of the cylinder 1 is a portion of an ellipse, and the working trajectory surface of the tapered cutting tooth 6 is similar to the shape of the outer contour, which can resist the erosion of harder rock layers. A cylindrical tensioning retainer 7 is slidably connected externally to the tapered cutting tooth 6, facilitating the installation of the cutting tooth. The retainer connection ensures smooth rotation of the cutting tooth within the cutter holder. The cylindrical tensioning retainer 7 is internally slidably connected to the exterior of the cylindrical cutter holder 5, facilitating installation and fixing. The connecting disc 2 is fixed to the cylinder 1 by welding, thereby improving overall stability.

[0026] Working Principle: First, the hydraulic motor is started to provide power to the vertical shaft drum structure. As the hydraulic motor rotates, the power is transmitted to the cylinder 1 via the connecting plate 2, causing the cylinder 1 to rotate. The rotation of the cylinder 1 causes the cylindrical cutter holder 5 and the conical cutting teeth 6 on it to rotate together, and the conical cutting teeth 6 begin to excavate the rock in the vertical shaft. During the excavation process, the conical cutting teeth 6, with their drum-shaped design and high-chromium wear-resistant welding wire, resist the erosion of the rock strata and provide a centering effect, ensuring the stable progress of the excavation work. The crushed material gathers towards the center under the combined action of the grooves on the outer arc surface of the cylinder 1 and the arrangement of the conical cutting teeth 6, waiting for the material receiving device in the middle to suck up and send the material out.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
