Description

Technical Field

[0001] This utility model relates to the field of power application technology, and more specifically, to a tool for quickly disassembling cable elbow sleeves. Background Technology

[0002] During emergency repairs of cable lines, it was found that cable elbow sleeves are very difficult to remove. Currently, the main methods for removing elbow sleeves from cable junction boxes and ring main units are conventional tools such as wrenches, pliers, screwdrivers, and rope binding methods. Sometimes this takes several hours and may even damage the elbow sleeve before it can be removed.

[0003] Currently, there are no specialized tools for dismantling cable elbow sleeves in the field of power operations. This not only fails to improve the efficiency of power emergency repairs but also threatens the lives of workers. Furthermore, prolonged power outage repairs not only cause economic losses but also seriously damage the image of power supply companies. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for quickly disassembling cable elbow sleeves, in order to solve the problem that there is currently no professional tool for disassembling cable elbow sleeves in the field of power operations. This not only fails to improve the efficiency of power emergency repairs and threatens the lives of workers, but also causes economic losses due to excessively long power outage repair times, and seriously affects the image of power supply companies.

[0005] To achieve the above objectives, a tool for quickly disassembling cable elbow sleeves is provided, comprising a housing, an inner groove, a through hole at the bottom of the inner groove, a threaded rod threadedly connected inside the through hole, a servo motor fixedly connected to the outer side of the bottom end of the threaded rod, a connecting rod at the top end of the threaded rod, a fixed wheel at the top end of the connecting rod, and arc-shaped rods movably arranged on both sides of the connecting rod, each arc-shaped rod also having a fixed wheel at its top end. The bottom end of the arc-shaped rod is located inside the inner groove, and a linkage component is provided between the bottom end of the arc-shaped rod and the threaded rod. Grips are fixedly connected to the vertical parallel sides of the housing.

[0006] As a further improvement to this technical solution, the linkage component includes a trapezoidal block fixed to the top of the threaded rod, the bottom end of the connecting rod fixed to the top of the trapezoidal block, and a rotating wheel rotatably connected to the bottom end of the arc-shaped rod rolling on the inclined surfaces on both sides of the trapezoidal block.

[0007] As a further improvement to this technical solution, the connecting rod and the fixed wheel at the top of the arc rod are all connected in a fixed manner, and the three fixed wheels are simultaneously in contact with elbow sleeves on their outer sides.

[0008] As a further improvement to this technical solution, a short column is fixedly connected to the middle of the pair of arc-shaped rods, and the two ends of the short column are rotatably connected to the inner sidewall of the accommodating groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This quick-release cable elbow sleeve tool is easy to use and can be operated by a single person, reducing the labor intensity of workers. It changes the traditional method of pulling with ropes, avoiding damage to the elbow sleeve, mobilizing the enthusiasm of on-site workers, shortening emergency repair time, reducing user complaint rate, and solving the problem of long power outage time for cable lines. Furthermore, through the setting of linkage components, the equipment can limit and clamp elbow sleeves of different sizes within the opening angle of the arc rod, thereby improving the practicality of the equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] Please see Figures 1-2 As shown, this utility model embodiment provides a tool for quickly disassembling cable elbow sleeves, which includes the following solutions:

[0018] Specifically, the device includes an outer casing 1, an inner cavity 2, a through hole 3 at the bottom of the cavity 2, a threaded rod 4 threadedly connected inside the through hole 3, a servo motor 5 fixedly connected to the outer side of the bottom of the threaded rod 4, a connecting rod 6 at the top of the threaded rod 4, a fixed wheel 7 at the top of the connecting rod 6, and curved rods 8 movably arranged on both sides of the connecting rod 6. The top of each curved rod 8 is also equipped with a fixed wheel 7. The bottom of the curved rod 8 is located inside the cavity 2, and a linkage component is provided between the bottom of the curved rod 8 and the threaded rod 4. The outer casing 1 is vertical. A gripping rod 9 is fixedly connected to both sides of the parallel rod; the linkage assembly includes a trapezoidal block 10 fixedly connected to the top of the threaded rod 4, and the bottom end of the connecting rod 6 fixedly connected to the top of the trapezoidal block 10. The inclined surfaces on both sides of the trapezoidal block 10 have a rotating wheel 11 that is rotatably connected to the bottom of the arc rod 8; the connecting rod 6 and the fixed wheel 7 at the top of the arc rod 8 are both fixedly connected, and the outer sides of the three fixed wheels 7 are synchronously contacted by an elbow sleeve 12; a short column 13 is fixedly connected to the middle of a pair of arc rods 8, and the two ends of the short column 13 are rotatably connected to the inner wall of the groove 2.

[0019] The above technical solution involves activating the servo motor 5 to rotate the threaded rod 4 within the groove 2 inside the housing 1. This causes the threaded rod 4 to rotate within the through hole 3 while simultaneously moving into the groove 2, allowing the fixed wheel 7 at the top of the connecting rod 6 to contact the outside of the elbow sleeve 12. Because a trapezoidal block 10 is fixed between the top of the threaded rod 4 and the bottom of the connecting rod 6, and rotating wheels 11, rotatably connected to the bottom of the arc-shaped rod 8, roll on the inclined surfaces of the trapezoidal block 10, the rotation of the threaded rod 4 into the groove 2 synchronously drives the trapezoidal block 10 upwards, pushing the rotating wheel 11 at the bottom of the arc-shaped rod 8 downwards from the top of the inclined surface of the trapezoidal block 10. Simultaneously, this drives the pair of arc-shaped rods 8 and the short column 13 around the centerline of the elbow sleeve 12. The three fixed wheels 7 rotate in opposite directions on the inner wall of the trough 2, so that the fixed wheels 7 fixed to the top of the pair of arc rods 8 limit and fix two opposite points on the upper outer side of the elbow sleeve 12. At this time, the three fixed wheels 7 are positioned in a triangle to fix the outer side of the elbow sleeve 12, making it convenient for the staff to pull the elbow sleeve 12 outward and remove it by holding the lever 9. By rotating the rotating wheel 11 to the bottom of the arc rod 8, the friction between the rotating wheel 11 and the inclined surface of the trapezoidal block 10 is reduced by rolling, which makes it convenient to position the elbow sleeve 12. The fixed wheels 7 are fixed to the top of the arc rod 8, which on the one hand makes it convenient to limit and fix the elbow sleeve 12, and on the other hand, the circular arc surface of the fixed wheel 7 can meet the limit of elbow sleeves 12 of different sizes.

[0020] Working principle: Before starting, the operator aligns the equipment with the bottom end of the horizontal surface of the elbow sleeve 12. Then, the servo motor 5 is activated to adjust the threaded rod 4 up and down until the outer side of the elbow sleeve 12 contacts the fixed wheel 7 at the top of the connecting rod 6. Next, the servo motor 5 is activated to drive the threaded rod 4 into the groove 2. This movement causes the trapezoidal block 10 and the connecting rod 6 to move upwards synchronously. As the trapezoidal block 10 moves, the rotating wheels 11 on both sides of the inclined plane roll downwards on the inclined plane, simultaneously driving the arc-shaped rod 8 and... The fixed wheels 7 at the top of the arc rod 8 rotate in opposite directions on the inner wall of the groove 2 with the center line of the elbow sleeve 12 as the axis. The rotation of the fixed wheels 7 at the top of the arc rod 8 will squeeze and limit the outer side of the elbow sleeve 12, so that the bottom end of the elbow sleeve 12 is located at the midpoint of the fixed wheel 7 at the top of the connecting rod 6. At this time, the fixed wheels 7 at the top of the arc rod 8 will limit the elbow sleeve 12 at two opposite points above the outer side, forming a triangular positioning to ensure that the equipment stably fixes the elbow sleeve 12. Finally, the operator can pull the elbow sleeve 12 outward by holding the handle 9.
