Description

Technical Field

[0001] This utility model relates to the technical field of mineral resource development equipment, specifically to a drug delivery pipe reel rotary device. Background Technology

[0002] Currently, with the increasing market demand for mechanization and unmanned operation in mining blasting, mining blasting is developing towards mechanization and unmanned (or minimally manned) operation. On-site blasting is shifting towards mechanized loading and on-site mixed loading. In on-site mixed loading equipment, the delivery hose reel serves a dual purpose: winding and unwinding the delivery hose. Emulsion explosives, as a type of civilian explosive, are flammable and explosive. Existing delivery hose reel slewing devices directly fix the slewing seat to the reel column, serving the dual function of supporting the reel and conveying explosives. When the seal needs to be replaced after a period of use, the delivery hose reel must be disassembled to remove the slewing seat, which is very inconvenient. Furthermore, when the seal is damaged, explosives enter the slewing device, and during the continuous rotation of the reel, dry friction occurs at the directly contacted parts, posing a high safety risk. Utility Model Content The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a drug delivery tube reel rotation device that is simple in structure, easy to disassemble and has a high safety factor.

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A drug delivery tube reel rotation device includes a reel bearing shaft, a rotating seat, and a support sleeve. The rotating seat is rotatably fitted around the outer periphery of the support sleeve. A first sealing assembly is provided between the first end of the rotating seat and the support sleeve. The reel bearing shaft is disposed on the drug delivery tube reel. The rotating seat and the reel bearing shaft are detachably connected. The reel bearing shaft has a hollow structure and communicates with the support sleeve.

[0004] As a further improvement to the above technical solution: the first sealing assembly includes two or more first sealing elements, and each first sealing element is distributed at intervals along the axial direction of the rotating seat.

[0005] As a further improvement to the above technical solution: the support sleeve is provided with a wear-resistant guide ring between two adjacent first seals, the inner wall of the first end of the rotating seat is provided with a receiving groove corresponding to the wear-resistant guide ring, and there is a gap between the inner wall of the first end of the rotating seat and the outer wall of the support sleeve.

[0006] As a further improvement to the above technical solution: the first sealing element is a shaft Glyd ring.

[0007] As a further improvement to the above technical solution: a second sealing element is provided between the end of the first end of the rotating seat and the end of the drum bearing shaft.

[0008] As a further improvement to the above technical solution: the second sealing element is an O-ring.

[0009] As a further improvement to the above technical solution: the drum bearing shaft is provided with a first flange connection part, and the rotating seat is provided with a second flange connection part. The first flange connection part and the second flange connection part are detachably connected by fasteners.

[0010] As a further improvement to the above technical solution: a bearing assembly is provided between the second end of the rotating seat and the support sleeve.

[0011] As a further improvement to the above technical solution: the bearing assembly includes two bearings spaced apart along the axial direction of the rotating seat, and a spacer is provided between the two bearings.

[0012] As a further improvement to the above technical solution: the bearing assembly is provided with a retaining ring for the hole and a retaining ring for the shaft on both sides of the axial direction.

[0013] Compared with the prior art, the advantages of this utility model are as follows: The medicated tubing reel rotating device disclosed in this utility model, in use, has a reel bearing shaft fixedly connected to a reel column, with the medicated tubing wound around the reel column. A rotating seat is rotatably fitted onto the outer circumference of a support sleeve. During operation, the support sleeve remains stationary, while the rotating seat rotates relative to the support sleeve. The rotating seat, along with the reel bearing shaft and the reel column, rotates together to achieve the rotating motion of the medicated tubing reel, thereby realizing the take-up and unwinding of the medicated tubing. Furthermore, by providing a first sealing component between the first end of the rotating seat and the support sleeve, the rotating seat and the support sleeve are sealed and isolated, preventing emulsion explosives from entering the gap between the support sleeve and the rotating seat, thus ensuring the safety of the device. The rotating seat and the drum bearing shaft are detachably connected. When replacing the first sealing component, this drug delivery tube drum rotation device only requires disassembling the connection between the rotating seat and the drum bearing shaft, compared to a rotation device where the rotating seat is directly fixed to the drum column. It does not require disassembling the drug delivery tube drum, making it easier to replace the first sealing component and greatly improving efficiency. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, the drug delivery tube reel rotation device of this embodiment includes a reel bearing shaft 1, a rotating seat 2, and a support sleeve 3. The rotating seat 2 is rotatably sleeved on the outer periphery of the support sleeve 3. A first sealing component 6 is provided between the first end of the rotating seat 2 and the support sleeve 3. The reel bearing shaft 1 is disposed on the drug delivery tube reel. The rotating seat 2 and the reel bearing shaft 1 are detachably connected. The reel bearing shaft 1 has a hollow structure and is connected to the support sleeve 3. Figure 3 (The emulsion explosive can flow from left to right).

[0024] In this tactical delivery tube reeling device, the drum bearing shaft 1 is fixedly connected to the drum column. The tactical delivery tube (hose) is wound around the drum column. A rotating seat 2 is rotatably fitted onto the outer circumference of a support sleeve 3. During operation, the support sleeve 3 remains stationary, while the rotating seat 2 rotates relative to the support sleeve 3. The rotating seat 2, along with the drum bearing shaft 1 and the drum column, rotates together to achieve the tactical delivery tube reeling motion, thereby realizing the winding and unwinding of the tactical delivery tube. Furthermore, by providing a first sealing component 6 between the first end of the rotating seat 2 and the support sleeve 3, the rotating seat 2 and the support sleeve 3 are sealed and isolated, preventing emulsion explosives from entering the gap between the support sleeve 3 and the rotating seat 2, thus ensuring the safety of the device. The rotating seat 2 is detachably connected to the drum bearing shaft 1. When replacing the first sealing component 6, compared with the rotary device that directly fixes the rotating seat 2 to the drum column, this drug delivery tube drum rotary device only needs to disassemble the connection between the rotating seat 2 and the drum bearing shaft 1, without having to disassemble the drug delivery tube drum, making it easier to replace the first sealing component 6 and greatly improving efficiency.

[0025] like Figure 3 As shown, in this embodiment, the first sealing assembly 6 includes two first sealing elements 61 (of course, more than two first sealing elements 61 can be provided in other embodiments), and each first sealing element 61 is distributed at intervals along the axial direction of the rotating seat 2. By providing two first sealing elements 61, multi-level sealing is achieved, which improves the leakage prevention capability, prevents emulsion explosives from entering the gap between the rotating seat 2 and the support sleeve 3, and further improves the safety of the device.

[0026] like Figure 3 As shown, in this embodiment, the support sleeve 3 is provided with a wear-resistant guide ring 7 between two adjacent first seals 61. A receiving groove is provided on the inner wall of the first end of the rotating seat 2 corresponding to the wear-resistant guide ring 7. There is a gap between the inner wall of the first end of the rotating seat 2 and the outer wall of the support sleeve 3. By providing the wear-resistant guide ring 7 between two adjacent first seals 61, it serves a supporting and guiding function. Combined with the gap between the inner wall of the first end of the rotating seat 2 and the outer wall of the support sleeve 3, the rotation of the rotating seat 2 on the support sleeve 3 only generates friction and wear on the wear-resistant guide ring 7. This avoids direct contact and dry grinding between the rotating seat 2 and the support sleeve 3 after the first seals 61 wear and fail, greatly improving the reliability and service life of the device.

[0027] like Figure 3 As shown, in this embodiment, the first sealing element 61 is a shaft Glyd ring. The self-sealing effect of the shaft Glyd ring results in a good sealing performance.

[0028] like Figure 3As shown, in this embodiment, a second sealing element 9 is provided between the end of the first end of the rotating seat 2 and the end of the drum bearing shaft 1. By providing the second sealing element 9 between the end of the first end of the rotating seat 2 and the end face of the drum bearing shaft 1, it is beneficial to prevent emulsion explosives from entering the joint between the rotating seat 2 and the drum bearing shaft 1, thereby further ensuring the safety of the device.

[0029] like Figure 3 As shown, in this embodiment, the second sealing element 9 is an O-ring. O-rings are low in cost, easy to install when replacing, and have a good sealing effect.

[0030] like Figures 1 to 3 As shown in this embodiment, the drum bearing shaft 1 is provided with a first flange connection part 11, and the rotating seat 2 is provided with a second flange connection part 21. The first flange connection part 11 and the second flange connection part 21 are detachably connected by fasteners 4 (such as bolts, screws, etc.). By setting the first flange connection part 11, the second flange connection part 21 and the fasteners 4, the two separate parts of the drum bearing shaft 1 and the rotating seat 2 are detachably connected, which has good reliability and is convenient for disassembly and assembly. When the device needs to be disassembled to replace the seal, the connection between the rotating seat 2 and the drum bearing shaft 1 can be disconnected simply by removing and installing the fasteners 4, without disassembling the drug delivery tube drum, which greatly improves the efficiency of maintenance and repair.

[0031] like Figure 1 and Figure 3 As shown, in this embodiment, a bearing assembly 5 is provided between the second end of the rotating seat 2 and the support sleeve 3. By setting the bearing assembly 5, the rotating seat 2 is ensured to rotate smoothly on the support sleeve 3, making the drug delivery tube take-up and untake-up actions smoother.

[0032] like Figure 3 As shown, in this embodiment, the bearing assembly 5 includes two bearings 51 spaced apart along the axial direction of the rotating seat 2, with a spacer 83 between the two bearings 51. By setting the two bearings 51 spaced apart along the axial direction to share the load, the number of support points is increased, and the stability of the rotating seat 2 on the support sleeve 3 is improved.

[0033] like Figure 3 As shown, in this embodiment, the bearing assembly 5 is provided with a retaining ring 81 for the bore and a retaining ring 82 for the shaft on both axial sides. By setting the retaining rings 81 for the bore and 82 for the shaft, the bearing assembly 5 is axially positioned, preventing movement and greatly improving the stability and reliability of the device.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
