Description

Technical Field

[0001] This utility model relates to the technical field of pipeline material conveying equipment in building engineering and water conservancy engineering, and in particular to a cement and fly ash inlet pipe anti-detachment device. Background Technology

[0002] In modern engineering fields such as water conservancy, construction, and transportation, concrete is a primary structural material. Cement and fly ash, as important components of concrete, require a continuous and stable supply during construction. Especially in large-volume concrete pouring projects, such as large dams and bridge foundations, the large volume of concrete and long construction period place even higher demands on the storage and transportation systems for cement and fly ash.

[0003] Currently, common cement and fly ash storage systems typically employ a silo structure with a feed inlet at the bottom to receive materials transported and unloaded by tank trucks. Taking a dam concrete production system as an example, this system is equipped with multiple cement and fly ash silos, each with a feed inlet at the bottom, which connects to the tank truck's discharge hose via flanges to facilitate material transport.

[0004] However, during actual construction, it was found that there is a significant risk of detachment at the connection between the tanker truck unloading point and the storage tank inlet. This is mainly due to factors such as vibration, wind disturbance, and accidental contact by operators during tanker truck unloading, which can cause the connecting flange to loosen or even completely detach, leading to unloading interruptions and material leaks. This not only affects storage efficiency but may also cause environmental pollution and safety hazards. In addition, frequent connection adjustments and repeated connections increase the intensity of manual labor and reduce overall construction efficiency, especially in high-intensity, continuous large-volume concrete construction, where this problem is particularly prominent.

[0005] Therefore, there is an urgent need to design a cement and fly ash feed inlet anti-detachment device that is structurally sound, easy to operate, and safe and reliable, so as to effectively prevent the accidental detachment of the connecting pipe during the unloading process of the tanker truck, improve the stability and safety of the feeding operation, and ensure the continuity of concrete production. Utility Model Content

[0006] To solve the above problems, this utility model provides a device to prevent the inlet pipe of cement and fly ash from detaching.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A cement and fly ash feed inlet anti-detachment device includes an operating handle, an arc-shaped hoop rotatably installed at the end of the operating handle, a wire rope adjusting nut threadedly connected to the operating handle, and a wire rope.

[0009] The wire rope passes around the pipe opening, and its two ends are connected to the wire rope adjusting nut. By rotating the operating handle, the wire rope adjusting nut moves vertically on the operating handle under the limiting action of the wire rope, so that the wire rope and the arc-shaped hoop cooperate to clamp the pipe opening.

[0010] Furthermore, the operating handle is T-shaped overall, with a horizontal operating lever at the top; gripping anti-slip rubber sleeves are installed at both ends of the operating lever; a threaded rod is welded and fixed at the center of the bottom of the operating lever, and a wire rope adjusting nut is threaded onto the threaded rod; an arc-shaped hoop is rotatably installed at the bottom of the threaded rod via a bearing.

[0011] Furthermore, the arc-shaped hoop includes two arc-shaped steel pipes spaced apart, which are fixed together by welding several connecting rods, and the two arc-shaped steel pipes form limiting grooves for matching steel wire ropes at both ends of the arc-shaped hoop.

[0012] Furthermore, the wire rope is a single wire rope folded in half to form a double-strand wire rope. The ends of the double-strand wire rope are fixedly connected to the wire rope adjusting nut, and the folded ends are also attached to the wire rope adjusting nut.

[0013] Furthermore, a U-shaped shackle is welded and fixed on one side of the outer wall of the wire rope adjusting nut, and a hook is welded and fixed on the other side of the outer wall; the rope end of the double-strand wire rope is fixed by a U-shaped wire rope clip after passing over the U-shaped shackle.

[0014] The beneficial effects of this utility model are:

[0016] 1. Effectively prevents pipe connections from detaching, improving operational safety:

[0017] By setting up a clamping structure consisting of an operating handle, an arc-shaped hoop, a wire rope, and a wire rope adjusting nut, the unloading hose of the tanker can be quickly locked and fixed after it is connected to the inlet of the storage tank. This effectively prevents the connection from loosening or even falling off due to vibration, wind, or human error, and significantly improves the safety of unloading operations.

[0018] 2. Easy to operate, improving construction efficiency:

[0019] This device uses a T-shaped operating handle with a rotatable arc-shaped hoop structure, which facilitates quick installation and disassembly by on-site personnel. The wire rope can be tightened and released by rotating the handle, without the need for complicated tools, which greatly reduces manual operation time and improves feeding efficiency.

[0020] 3. High structural strength and strong adaptability:

[0021] The arc-shaped hoop is welded from two arc-shaped steel pipes and a connecting rod. The overall structure is sturdy and durable, and can adapt to pipe connection parts of different diameter specifications. It is highly versatile and suitable for connection scenarios between cement and fly ash tank trucks and storage tanks of various models.

[0022] 4. Controllable clamping force, stable and reliable connection:

[0023] The wire rope adopts a double-strand folded structure, and the tension is controlled by adjusting the nut. The clamping force can be adjusted according to actual needs to ensure a firm connection without damaging the pipe surface, thus ensuring the stability and sealing of the connection.

[0024] 5. Modular component design for easy maintenance and replacement:

[0025] The components are assembled using connectors, such as U-shaped shackles and hooks, which facilitates daily maintenance and replacement, reduces operating costs, and extends the service life of the device.

[0026] 6. Wide range of applications and broad prospects:

[0027] This device is not only suitable for large-volume concrete pouring systems at water conservancy construction sites, but can also be widely used in various storage tank in construction engineering, transportation engineering and other fields involving the conveying of powdery materials to prevent the feed interface from coming loose. It has good promotion and application value. Attached Figure Description

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.

[0032] To effectively prevent accidental detachment of the connecting pipe during tanker unloading, improve the stability and safety of the feeding operation, and ensure the continuity of concrete production, this embodiment provides a cement and fly ash feed inlet pipe anti-detachment device; such as Figure 1 As shown, the cement and fly ash feed inlet anti-detachment device includes an operating handle 1, an arc-shaped hoop 2 rotatably installed at the end of the operating handle 1, a wire rope adjusting nut 3 threadedly connected to the operating handle 1, and a wire rope 4. The device has a simple structure and is easy to operate. It can effectively prevent the pipe opening 5 from falling off during the unloading process due to vibration, wind or accidental collision, and improve the safety and stability of the feeding operation. It is suitable for continuous cement and fly ash supply systems in large-volume concrete construction and has good application prospects.

[0033] To facilitate understanding of the working principle of the cement and fly ash inlet pipe anti-detachment device, its structure and function are described in detail below:

[0034] Operating handle 1:

[0035] like Figure 1 and Figure 2 As shown, the operating handle 1 in this embodiment is T-shaped and is constructed by welding a steel pipe and a threaded rod 13. The top of the operating handle 1 is a horizontal operating rod 11. For ease of rotation, anti-slip grip sleeves 12 are installed at both ends of the operating rod 11. A threaded rod 13 is welded and fixed to the center of the bottom of the operating rod 11. The threaded rod 13 and the operating rod 11 form an integral T-shaped structure. A wire rope adjusting nut 3 is threaded onto the threaded rod 13, and an arc-shaped clamp 2 is rotatably mounted on the bottom of the threaded rod 13 via a bearing 14.

[0036] The operating handle 1 serves as the control component for the entire device, used for manual rotation to adjust the tension of the wire rope 4. Its T-shaped design facilitates the application of force, and the operating lever 11 has anti-slip rubber sleeves at both ends to improve grip comfort and safety.

[0037] Arc-shaped hoop 2:

[0038] like Figure 1 and Figure 2 As shown, the arc-shaped hoop 2 in this embodiment includes two spaced-apart arc-shaped steel pipes 21, which are fixed together by three connecting rods 22. The arc-shaped hoop 2 surrounds the upper part of the pipe opening 5, serving as a support structure and forming a clamping force together with the wire rope 4 to prevent the pipe opening 5 from falling off. The arc-shaped hoop 2 is made of arc-shaped steel pipes welded to the connecting rods 22, and has good structural strength and stability.

[0039] Furthermore, as a preferred technical solution in this embodiment, to prevent the wire rope 4 from shifting or slipping, such as... Figure 1 and Figure 2 As shown, in this embodiment, the two arc-shaped steel pipes 21 of the arc-shaped hoop 2 form limiting grooves 23 at both ends of the arc-shaped hoop 2 to guide and position the wire rope 4, prevent the wire rope 4 from deviating or slipping, and improve clamping stability.

[0040] Wire rope 4 and wire rope adjusting nut 3:

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the wire rope 4 is a single wire rope folded in half to form a double-strand wire rope. The double-strand wire rope passes around the pipe opening 5 and is connected to the adjusting nut. The tension force presses the arc-shaped hoop 2 tightly around the flange connection, which plays a role in preventing detachment and fixing. The double-strand structure of the wire rope 4 improves the load-bearing capacity and reliability.

[0042] A U-shaped shackle 31 is welded and fixed to one side of the outer wall of the wire rope adjusting nut 3, and a hook 32 is welded and fixed to the other side of the outer wall. The rope end 41 of the double-strand wire rope passes over the U-shaped shackle 31 and is fixed by the U-shaped wire rope clamp 33. The folded end 42 is connected to the wire rope adjusting nut 3 by the hook 32. The U-shaped shackle 31 and the U-shaped wire rope clamp 33 are commercially available finished products, and their detailed structure will not be described in detail here.

[0043] The working principle of the cement and fly ash inlet pipe anti-detachment device described above is as follows:

[0044] When using, install Figure 3 As shown, install the cement and fly ash feed inlet anti-detachment device. After determining the installation position, hang the folded end 42 of the wire rope 4 on the hook 32 of the wire rope adjusting nut 3. At this time, the pipe opening 5 can be clamped by using the operating handle 1.

[0045] During operation, by rotating the operating handle 1, the wire rope adjusting nut 3 moves vertically on the operating handle 1 under the limiting action of the wire rope 4, thereby driving the wire rope adjusting nut 3 to tighten the wire rope 4. Together with the arc-shaped hoop 2, it surrounds and clamps the pipe opening 5, realizing the rapid locking of the flange connecting the tank truck and the storage tank. This effectively prevents the pipe opening 5 from falling off due to factors such as vibration and wind during the unloading process, ensuring operational safety and efficiency.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
