Description

Technical Field

[0001] This utility model belongs to the field of pipeline engineering applications, specifically relating to a portable detachable transmission device and cable winding and unwinding equipment. Background Technology

[0002] With the rapid pace of global urbanization, global warming, and extreme weather events, urban flooding has become a serious problem. Underground drainage networks are expanding and extending at a rapid pace, and existing drainage pipes are playing an increasingly important role in ensuring drainage. However, over time, the natural aging and damage to these networks have brought about a series of problems.

[0003] To address this, the industry has introduced equipment for municipal pipeline inspection, maintenance, and repair, all of which require cable reeling / delivery equipment. Existing cable reeling / delivery equipment comes in two structures: large and small. Large reeling / delivery equipment is suitable for long-distance cable reeling / delivery; it has a larger structure, and the transmission device is generally located outside the reel, occupying a significant amount of space. Small cable reeling / delivery equipment, on the other hand, is suitable for short-distance cable reeling / delivery. Due to its smaller overall structure, its transmission device is generally integrated inside the reel. If the drive motor malfunctions, the entire equipment must be disassembled for repair, making repairs very difficult. Utility Model Content

[0004] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model proposes a portable detachable transmission device and cable winding and unwinding equipment.

[0005] To achieve the above objectives, according to one aspect of this utility model, a portable and detachable transmission device is provided, comprising: The main body is designed for detachable external connection with cable retraction equipment; The drive mechanism is fixed in the body and has a drive shaft; An axial connector is disposed on the inner side of the main body. One end of the axial connector is fixedly connected to the drive shaft, and the other end of the axial connector is used for transmission connection from the outside of the cable winding device to the winding reel inside the cable winding device.

[0006] According to the above-described device, the cable winding and unwinding equipment has an inwardly recessed cavity on its exterior, which extends into the interior of the cable reel, and the main body is disposed in the cavity.

[0007] According to the above device, the outer side of the main body is provided with a flange, and the flange is provided with a mounting hole for detachable connection with the external cable winding and unwinding device.

[0008] According to the above-described device, the winding reel is provided with a first positioning device; The axial connector is provided with a second positioning device that matches the first positioning device.

[0009] According to the above-described device, the first positioning device is an axially connected positioning mandrel and a first flange shaft; The axial connector is a second flange shaft, which is connected to the positioning mandrel and the first flange shaft via a spline groove.

[0010] In the above-described device, the driving mechanism is a motor.

[0011] According to the above-described device, a handle is provided on the outer side of the main body.

[0012] According to another aspect of the present invention, a cable winding and unwinding device is provided, including a cable reel and a transmission device for driving the cable reel to rotate. The transmission device is the portable, detachable transmission device described above.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "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, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] This utility model provides a cable winding and unwinding device, such as... Figures 1 to 3 As shown, the device includes a frame 6, inside which is a cable reel 4. The cable reel 4 is connected to the frame 6 via a first turntable bearing K1 and a second turntable bearing K2, which allows the cable reel 4 to rotate flexibly, thereby stably and orderly winding the cable 5 onto the cable reel 4.

[0029] Continue as Figures 1 to 3 As shown, the cable winding and unwinding equipment also includes a transmission device 1 for driving the cable reel 4 to rotate; the transmission device 1 is a portable and detachable transmission device. Specifically, the frame 6 is provided with a cavity K, the opening of which faces the outside of the cable winding and unwinding equipment, i.e., it is recessed from the outside of the cable winding and unwinding equipment. The transmission device 1 is embedded in the cavity K from the outside of the cable winding and unwinding equipment and is connected to the cable reel 4 located inside the cable winding and unwinding equipment.

[0030] This utility model sets the transmission device 1 as an independent unit, which can be detachably connected to the frame 6 from the outside of the cable winding and unwinding equipment. This not only enables transmission connection with the cable winding reel inside the cable winding and unwinding equipment, but also facilitates disassembly and maintenance.

[0031] Preferably, the cavity K extends into the interior of the winding reel 4, thereby utilizing the space inside the winding reel 4 to make the space more compact.

[0032] like Figure 2 As shown, the portable and detachable transmission device provided by this utility model includes a body 1-1, a drive mechanism 1-2, and an axial connecting member.

[0033] The main body 1-1 is mainly used for detachable external connection with the cable winding and unwinding device. In this embodiment, the outer side of the main body 1-1 is provided with a flange, and the flange is provided with a mounting hole for detachable external connection with the cable winding and unwinding device. Specifically, it is connected by bolts, but other connection methods can also be used.

[0034] The drive mechanism 1-2 is fixed in the body 1-1 and has a drive shaft. In this embodiment, the drive mechanism 1-2 is a drive motor, but other types of drive mechanisms can also be used. As long as they have a drive shaft and can be connected to the winding reel 4 to drive the winding reel 4 to rotate, they are all within the protection scope of this utility model.

[0035] The axial connector is located inside the body 1-1. One end of the axial connector is fixedly connected to the drive shaft, and the other end of the axial connector is connected from the outside of the cable winding device to the winding reel 4 inside the cable winding device.

[0036] Furthermore, to better achieve rapid alignment and connection, the winding reel 4 is equipped with a first positioning device, and the axial connector is equipped with a second positioning device that matches the first positioning device. The two are aligned and connected through the cooperation of the first and second positioning devices. More specifically, the first positioning device may be an axially connected positioning mandrel 2 and a first flange shaft 3, and the axial connector may be a second flange shaft 1-3, which is connected to the positioning mandrel 2 and the first flange shaft 3 through a spline groove.

[0037] To better facilitate the assembly and disassembly of the transmission device 1, a handle 1-4 can be added to the outside of the main body 1-1.

[0038] To better enable power supply to the drive mechanism 1-2, a power supply box is installed on the frame 6, located to the side of the cavity K. The power cable for the drive mechanism 1-2 extends from the side of the main body 1-1 and is electrically connected to the power supply box.

[0039] In this embodiment, the installation steps of the transmission device 1 are as follows: insert the body 1-1 of the transmission device 1 into the cavity K corresponding to the frame 6, and push it forward along the center line of the cavity K until the second flange shaft 1-3 is inserted into the positioning mandrel 2; rotate the winding reel 4 so that the first flange shaft 3 on the winding reel is connected to the second flange shaft 1-3 of the transmission device 1; fix the mounting hole of the flange of the transmission device 1 to the frame 6 with bolts / screws; and electrically connect the power cable of the drive mechanism to the corresponding equipment power supply box.

[0040] When the transmission device 1 needs to be repaired, the disassembly steps of the transmission device 1 are as follows: disconnect the power cable of the drive mechanism from the corresponding equipment power box; remove the bolts / screws between the mounting hole of the flange of the transmission device 1 and the frame 6; pull the handles 1-4 and drag the transmission device 1 outward along the central axis of the winding reel 4 to remove the transmission device 1.

[0041] As can be seen from the above installation and disassembly steps, contrary to the traditional approach of integrating the transmission device 1 inside the cable reel 4, this invention separates the transmission device 1 from the cable reel 4, setting it as an independent unit. This unit is located separately from the cable reel 4, one outside and one inside the cable winding device, connected by an axial connector. This invention is particularly suitable for small cable winding devices, facilitating the maintenance of the transmission device while maintaining a compact structure.

[0042] It should be noted that, depending on the implementation needs, the various components described in this application can be divided into more components, or two or more components or parts of the operation of components can be combined into new components to achieve the purpose of this utility model.

[0043] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
