Description

Technical Field

[0001] This utility model relates to the field of wire tensioner technology, and more specifically, it relates to a wire tensioner for quick wire securing in power installations. Background Technology

[0002] Electrical installation refers to the process of pulling cables from power plants or substations to their destination. To avoid these cables affecting the use of normal roads and to reduce safety hazards, cables are pre-calculated and erected at intervals using cable trays to keep them away from the ground, thus avoiding the hassle of ground construction and reducing damage in the event of an accident.

[0003] The main method of pulling cables between cable trays is to pull the cables from the ground to the cable trays that need to be bridged, and then use a cable tensioner to wind up the cables on the cable trays, so that they are suspended between the two cable trays, thereby achieving the purpose of tightening the cables. This method is also known as the rapid cable fixing method.

[0004] However, common cable tensioners typically use a motor to drive the winding post to wind the cable when winding it up. During this process, the cable is randomly wound around the winding post. When laying cables over long distances, a large amount of cable wrapped around the winding post may cause a lot of cable to be wrapped around one end of the winding post. This can not only cause the cable to become tangled, but also, due to the weight of the cable, it can shift the overall center of gravity of the tensioner, affecting subsequent handling. In this case, it is usually necessary to manually intervene to make the cable wound more evenly. However, this is not only dangerous, but also affects the efficiency of fast cable fixing.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a fastening device for quick-fixing of electrical installation wires. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fastening device for electrical installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire tensioner for quick-fixing electrical installations, comprising:

[0008] A wire tensioner is provided, in which a motor is installed. The drive end of the motor is connected to a drive mechanism, which has two drive ends, each connected to a winding post and a guide mechanism. The winding post is rotatably mounted on the wire tensioner and has a cable wound on it. The guide mechanism includes a conductor block corresponding to the winding post, and the cable is slidably connected to the conductor block. The drive mechanism drives the winding post to rotate and also drives the guide mechanism to operate. The guide mechanism guides the cable while the winding post rotates.

[0009] Preferably, the driving mechanism includes a driving box located within the tensioner corresponding to the motor position. The driving mechanism also includes a driving shaft mounted on the motor driving end. One end of the driving shaft passes through the driving box and extends out of the tensioner to connect with the winding post. The portion of the driving shaft inside the driving box is connected to a driving gear. The driving gear meshes with a driven gear. A transmission shaft is connected to the driven gear. One end of the transmission shaft extends out of the driving box, and both the driven gear and the transmission shaft are rotatably connected to the driving box.

[0010] Preferably, the guiding mechanism includes a movable block installed on one end of the drive shaft extending out of the drive box, and the guiding mechanism also includes a movable rod slidably connected in the tensioner through multiple support seats. The movable rod is equipped with a movable frame and a wire block installed at the corresponding winding post position. The movable block is rotatably connected to the movable frame.

[0011] It is worth noting that the movable block is irregularly shaped. When the movable block rotates, different parts of the movable block will abut against the inside of the movable frame, causing the movable frame to deflect. Since the movable rod is limited by the support seat, the movable frame drives the movable rod to move inside the tensioner.

[0012] Preferably, the end of the winding post away from the drive shaft is connected to the tensioner via a hydraulic actuator, and a bearing is installed at the connection point between the tensioner and the hydraulic actuator;

[0013] The winding post can be fixed by extending or retracting the hydraulic device, thus allowing the winding post to be removed from the tensioner.

[0014] Preferably, the surface of the tensioner has an inlet corresponding to the position of the conductor block, which facilitates the worker to thread the cable into the conductor block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, the drive mechanism drives the winding column to wind the cable. At the same time, the conductor block moves with the rotation of the winding column, causing the cable passing through it to be wound around the winding column at an angle. This achieves more even winding of the cable on the winding drum, thus solving the problem in the prior art where the cable may pile up at one end of the winding column when the winding column winds the cable. It also avoids the overall center of gravity of the tensioner shifting, reduces manual intervention, and improves the cable fixing efficiency.

[0017] 2. In this utility model, the motor, through the connected drive mechanism, enables one power source to generate two drive modes, driving the winding column to rotate while also controlling the wire block to slide within the tensioner. This eliminates the need for multiple sets of power drive devices, reduces equipment costs, and improves the overall coordination of the equipment. Attached Figure Description

[0024] Example 1:

[0025] like Figure 1-4As shown, this utility model provides a fast wire tensioner for electrical installation, including a tensioner 1, a motor 5 installed inside the tensioner 1, a drive mechanism 6 connected to the drive end of the motor 5, the drive mechanism 6 having two drive ends, and the two drive ends of the drive mechanism 6 being respectively connected to a winding post 4 and a guide mechanism 8, the winding post 4 being rotatably mounted on the tensioner 1, and a cable being wound on the winding post 4, the guide mechanism 8 including a conductor block 83 corresponding to the winding post 4, the conductor block 83 being slidably connected to the cable, the drive mechanism 6 being used to drive the winding post 4 to rotate, and at the same time driving the guide mechanism 8 to rotate, the guide mechanism 8 being used to guide the cable while the winding post 4 is rotating;

[0026] In summary, compared to the traditional cable tensioner 1, which requires manual intervention to prevent uneven winding of the cable onto the winding post 4 during cable winding and tightening, the aforementioned drive mechanism 6 can drive the winding post 4 to wind the cable. At the same time, the drive mechanism 6 transmits power to the guide mechanism 8, and the cable passes through the conductor block 83 and winds onto the winding post 4. The conductor block 83 can drive the cable to move back and forth between the two ends of the winding post 4 and maintain a winding angle between the cable and the winding post 4. This allows the cable to wind more stably and evenly onto the winding post 4, thereby reducing the problem of unstable center of gravity of the cable tensioner 1 due to uneven winding of the cable, reducing the need for manual intervention, and lowering the risk of operation.

[0027] The drive mechanism 6 includes a drive box 64 located inside the tensioner 1 corresponding to the position of the motor 5. The drive mechanism 6 also includes a drive shaft 65 mounted on the drive end of the motor 5. One end of the drive shaft 65 passes through the drive box 64 and extends out of the tensioner 1 to connect with the winding post 4. The part of the drive shaft 65 inside the drive box 64 is connected to a drive gear 61. The drive gear 61 is meshed with a driven gear 62. A transmission shaft 63 is connected to the driven gear 62. One end of the transmission shaft 63 extends out of the drive box 64. Both the driven gear 62 and the transmission shaft 63 are rotatably connected to the drive box 64.

[0028] The guiding mechanism 8 includes a movable block 85 installed on one end of the drive shaft 63 extending out of the drive box 64. The guiding mechanism 8 also includes a movable rod 82 slidably connected to the tensioner 1 through a plurality of support seats 81. A movable frame 84 and a wire block 83 installed at the corresponding position of the winding post 4 are mounted on the movable rod 82. The movable block 85 is rotatably connected to the movable frame 84.

[0029] It is worth noting that the movable block 85 is irregularly shaped. When the movable block 85 rotates, different parts of the movable block 85 will abut against the inside of the movable frame 84, thereby causing the movable frame 84 to deflect. Since the movable rod 82 is limited by the support seat 81, the movable frame 84 drives the movable rod 82 to move within the tensioner 1.

[0030] Motor 5 drives the winding post 4 to rotate via drive shaft 65. The winding post 4 winds up the cable. At the same time, drive gear 61 also rotates with drive shaft 65. Drive gear 61 drives driven gear 62 to rotate. Driven gear 62 causes movable block 85 to rotate in movable frame 84 via transmission shaft 63. Different parts of movable block 85 abut against movable frame 84, causing movable frame 84 to drive movable rod 82 to slide back and forth in tensioner 1. At the same time, driven by movable rod 82, conductor block 83 drives the cable passing through it to maintain an angle on winding post 4 for winding. This allows the cable to be wound later to be wound close to the cable already wound on winding post 4 for winding, making the winding more even.

[0031] The end of the winding post 4 away from the drive shaft 65 is connected to the tensioner 1 via the hydraulic actuator 2, and a bearing 7 is installed at the connection position between the tensioner 1 and the hydraulic actuator 2.

[0032] The extension and retraction of the hydraulic device 2 can control the fixing of the winding post 4, thereby removing the winding post 4 from the tensioner 1, realizing quick disassembly and assembly of the winding post 4, and facilitating the storage of excess cable.

[0033] The tensioner 1 has an inlet 3 on its surface corresponding to the position of the conductor block 83. Through the inlet 3, workers can easily wind the cable onto the winding post 4 via the conductor block 83.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
