Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a novel branch box cap catcher. Background Technology

[0002] With the advancement of urbanization, urban power lines are becoming increasingly dense, and overhead power lines are presenting more and more safety problems, as well as affecting the aesthetics of the city. During power construction work, the grounding problem of cable branch boxes has always troubled workers, as conventional grounding tools cannot remove the dust caps from T-shaped cable heads.

[0003] For example, a branch box cap grabber disclosed in CN203003866U includes an insulating shell, a telescopic rod, and a telescopic grabber. The insulating shell is a sleeve, the telescopic rod is inserted through the inside of the insulating shell, and the telescopic grabber is composed of several grabber bodies. The bottom of each grabber body is hinged to the top of the insulating shell. A connecting rod is provided between the grabber body and the telescopic rod, with both ends of the connecting rod hinged to the middle part of the grabber body and the top of the telescopic rod, respectively. This utility model provides short-circuit grounding protection for buried cables in urban areas, reducing the scope of power outages and minimizing economic losses. This utility model has a simple structure, is easy to use, low in cost, simple to manufacture, and safe and reliable, making it suitable for large-scale use and promotion in the power industry.

[0004] The aforementioned patent proposes a telescopic gripper to remove the dust cap from the cable head. However, the dust cap is located in different positions in the branch box, and the length of the existing telescopic gripper cannot be adjusted, thus making it impossible to remove the dust cap from different positions and reducing the effectiveness of the device.

[0005] Therefore, we proposed a new type of branch box cap grabber to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0019] Please see Figure 1-5 A novel branch box cap grabber includes a circular tube 1. A connecting rod 2 is movably fitted inside the inner cavity of the circular tube 1. A grabbing component 3 is provided at the top of the connecting rod 2. An adjusting component 4 is provided between the connecting rod 2 and the circular tube 1. The adjusting component 4 includes connecting blocks 41 fixedly installed on both sides of the connecting rod 2 near the bottom. Reset telescopic rods 42 are fixedly installed on the opposite side of the connecting blocks 41 near the top and bottom. A locking block 43 is fixedly installed at the ends of two adjacent reset telescopic rods 42. Limiting grooves 44 are opened on both sides of the inner cavity of the circular tube 1. The connecting blocks 41 are slidably connected in the inner cavity of the adjacent limiting grooves 44. Several limiting ports 45 are opened on the opposite side of the inner cavity of the limiting grooves 44. The several limiting ports 45 are arranged linearly from top to bottom. The locking block 43 moves through the inner cavity of the limiting port 45 on the opposite side.

[0020] Specifically, when removing the dust cap, the length of the connecting rod 2 can be adjusted according to the position of the dust cap. The locking blocks 43 are pressed to the opposite side, and the two locking blocks 43 are located in the inner cavity of the limiting port 45. Then, the length of the connecting rod 2 can be adjusted by pulling it upward. This can be applied to removing dust caps from different positions, improving the effectiveness of the device.

[0021] The outer periphery of the reset telescopic rod 42 is movably fitted with a reset spring 421, and the two ends of the reset spring 421 are fixedly connected to the connecting block 41 and the locking block 43, respectively.

[0022] Specifically, by setting a reset spring 421, the locking block 43 can stably penetrate the inner cavity of the limiting port 45, thereby improving the positional stability of the connecting rod 2.

[0023] Dovetail blocks 21 are fixedly installed on both the front and rear sides of the connecting rod 2. Dovetail grooves 22 are opened on both the front and rear sides of the inner cavity of the round tube 1, and the dovetail blocks 21 are slidably connected in the inner cavity of the adjacent dovetail grooves 22 respectively.

[0024] Specifically, by setting the dovetail block 21 to slide in the inner cavity of the dovetail groove 22, the stability of the connecting rod 2 moving in the inner cavity of the round tube 1 can be improved. Example

[0025] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5 The picking component 3 includes a drive rod 34 that moves through the bottom of the inner cavity of the circular tube 1 (the drive rod 34 moves through the inner cavity of the circular tube 1 via a bearing). A knob 35 is fixedly installed at the bottom end of the drive rod 34, and a rectangular block 33 is fixedly installed at the top end of the drive rod 34. A rectangular groove 32 is movably fitted around the outer periphery of the rectangular block 33, and a threaded rod 31 is fixedly installed at the top end of the rectangular groove 32. (The outer periphery of the threaded rod 31 has opposite external threads near the top and bottom, and the thread precision is the same. When the threaded rod 31 rotates, the threaded sleeve 36 can move the same distance.) The top end of the threaded rod 31 moves through the inner cavity of the connecting rod 2. Threaded sleeves 36 are threadedly connected to the outer periphery of the threaded rod 31 near the top and bottom ends. A hinge rod 37 is hinged to the outer periphery of the threaded sleeve 36. The ends of two adjacent hinge rods 37 are hinged together to a movable plate 38. A connecting block is fixedly installed on the top of each movable plate 38, and a gripper 39 is fixedly installed on the opposite side of each connecting block.

[0026] Specifically, when the dust cap is removed, with the cooperation of the picking component 3, the rotation of the threaded rod 31 can move the two threaded sleeves 36 to opposite sides, thereby moving several grippers 39 to opposite sides to fix the dust cap in place without the need for manual removal.

[0027] Rubber blocks are fixedly installed on the opposite side of the gripper 39.

[0028] Specifically, setting up several rubber blocks can improve the stability of taking out the dust cap.

[0029] Limiting telescopic rods 381 are fixedly installed on one side of the front and rear movable plates 38, near the two sides.

[0030] Specifically, by setting the limit telescopic rod 381, the movement of the movable plate 38 can be limited, thereby improving its movement stability.

[0031] Working Principle: In use, the length of the connecting rod 2 is adjusted according to the position of the dust cap. While adjusting the connecting rod 2, the locking blocks 43 are pressed to opposite sides, causing them to be positioned within the limiting port 45. Then, the connecting rod 2 is pulled upwards to slide within the inner cavity of the round tube 1. After adjustment to a suitable position, the locking blocks 43, under the elastic force of the return spring 421, pass through the limiting port 45, thus limiting the adjusted position. This design is suitable for removing dust caps from different positions. The dust cap is positioned between the grippers 39 and can then be rotated... Turning the knob 35 causes the drive rod 34 fixed on the knob 35 to rotate. With the cooperation of the rectangular block 33 and the rectangular slot 32, the threaded rod 31 can rotate. The outer periphery of the threaded rod 31 has opposite external threads near the top and bottom, and the thread precision is the same. During the rotation of the threaded rod 31, the threaded sleeve 36 connected to the outer periphery of the threaded rod 31 can move to the opposite side. With the connection of the hinge rod 37, the movable plate 38 can move inward, thereby allowing the gripper 39 to fix the dust cap. Then, the round tube 1 can be pulled to remove the dust cap without manual removal. Example

[0032] This embodiment of the novel branch box cap grabber is suitable for maintenance work on 10kV-35kV outdoor cable branch boxes. It is especially useful for removing the dust caps of T-shaped cable heads in high places (1.5m-3m above the ground) or deep cavities (0.3m-1m deep) of branch boxes where workers cannot directly reach them. The following describes its implementation process in detail with specific work procedures.

[0033] I. Preparations before implementation Component inspection: The operator takes the device to the maintenance site and confirms the condition of each component: the rubber block inside the gripper 39 in component 3 is undamaged and unaged; the reset telescopic rod 42 in the adjustment component 4 extends and retracts flexibly, and the reset spring 421 is free from rust and deformation; the limit telescopic rod 381 is not stuck and can extend and retract smoothly; the dovetail block 21 and the dovetail groove 22 have normal clearance and are not stuck.

[0034] Initial state confirmation: At this time, the device is in the storage state, the connecting rod 2 is retracted into the inner cavity of the round tube 1, the locking block 43 is locked in the limiting port 45 at the bottom of the limiting groove 44, the total length of the cap grabber is 0.7m; the gripper 39 is in the naturally open state, the opening range is 8cm (suitable for T-type cable head dust caps with a diameter of 5cm-7cm).

[0035] II. Adjustable length of cap catcher (for high-altitude dust caps) Assuming the T-shaped cable head dust cap of the cable branch box is located on the side of the box 2.2m above the ground, and the maximum reachable height for a worker standing on the ground is 1.6m, the total length of the cap grabber needs to be adjusted to 1.3m (the connecting rod 2 extends 0.6m out of the round tube 1). The operating steps are as follows: The operator holds the middle part of the round tube 1 (0.3m from the bottom) and the upper part of the connecting rod 2 (0.2m from the top) with both hands respectively, and uses both thumbs to simultaneously press the locking blocks 43 on both sides of the round tube 1 in opposite directions; After being pressed, the locking block 43 moves toward the connecting block 41, simultaneously compressing the reset telescopic rod 42 and the reset spring 421 sleeved on its outer periphery, until the locking block 43 completely disengages from the currently locked limiting port 45 and retracts into the inner cavity of the limiting groove 44. Maintain the pressure of your thumb on the locking block 43 and slowly pull the connecting rod 2 upward: the connecting rod 2 drives the connecting blocks 41 on both sides to slide upward along the inner cavity of the limiting groove 44, while the dovetail blocks 21 on the front and rear sides of the connecting rod 2 slide axially along the dovetail groove 22 of the inner cavity of the round tube 1 (avoid the connecting rod 2 from rotating and ensure that the gripper 39 is always aligned with the direction of the dust cap). When the length of the connecting rod 2 extending out of the round tube 1 reaches 0.6m (confirmed by the length scale on the outer wall of the round tube 1, with scale intervals of 0.1m), stop pulling the connecting rod 2 and slowly release your thumb; The reset spring 421 resets under the action of elastic force, pushes the reset telescopic rod 42 to extend, and then drives the locking block 43 to move away from the connecting block 41 until the locking block 43 passes through the limit port 45 corresponding to the current height (at this time, the locking block 43 extends about 0.5cm out of the outer wall of the round tube 1), the relative position of the connecting rod 2 and the round tube 1 is fixed, and the total length of the cap grabber is stabilized at 1.3m.

[0036] III. Dust Cap Alignment and Fixing The operator stands with the lower part of the round pipe 1 (0.1m from the bottom) in hand. The operator aligns the gripper 39 of the picking component 3 with the dust cap of the T-shaped cable head inside the branch box. The operator visually adjusts the angle of the cap picker so that the dust cap is completely between the two grippers 39 (ensuring that the center of the dust cap coincides with the center of symmetry of the gripper 39). Keep the round tube 1 stable with both hands, and use the index and middle fingers of one hand to rotate the knob 35 at the bottom of the round tube 1 clockwise (the outer wall of the knob 35 has anti-slip texture to increase the friction of the hand): the knob 35 drives the drive rod 34 to rotate synchronously, and the rectangular block 33 at the top of the drive rod 34 rotates in the inner cavity of the rectangular groove 32 (the rectangular structure can transmit rotational force, and at the same time allows the rectangular block 33 to move slightly along the axial direction of the rectangular groove 32), which in turn drives the threaded rod 31 at the top of the rectangular groove 32 to rotate; Since the outer periphery of the threaded rod 31 has external threads with opposite directions and a pitch of 2mm near the top and bottom, and the upper and lower threaded sleeves 36 are respectively adapted to the external threads at the corresponding positions, when the threaded rod 31 rotates, the upper threaded sleeve 36 moves upward along the threaded rod 31, and the lower threaded sleeve 36 moves downward along the threaded rod 31 (the two move at the same speed). When the threaded sleeve 36 moves, the hinge rod 37 (a wear-resistant pad is provided at the hinge joint between the hinge rod 37 and the threaded sleeve 36 and the movable plate 38) pulls the movable plate 38 to move in the opposite direction. During the movement of the movable plate 38, the limiting telescopic rods 381 on the front and rear sides extend synchronously (the extension and retraction stroke of the limiting telescopic rod 381 matches the movement stroke of the movable plate 38) to prevent the movable plate 38 from shifting or tilting. As the movable plate 38 approaches, the grippers 39 fixed on the top connecting block of the movable plate 38 move synchronously in the opposite direction until the rubber block inside the grippers 39 tightly fits against the outer periphery of the dust cap (at this time, the operator can sense the degree of clamping by rotating the knob 35; when the resistance increases significantly, stop rotating to avoid over-clamping and damaging the dust cap), thus completing the fixing of the dust cap.

[0037] IV. Dust Cap Removal and Device Reset After the dust cap is fixed, the operator keeps his hands steady and slowly pulls the round tube 1 away from the cable branch box (the direction of the pulling force is parallel to the axis of the dust cap). The clamp 39 drives the dust cap to overcome the fitting resistance of the T-shaped cable head and detach it from the cable head. After removing the dust cap from the branch box, rotate the knob 35 counterclockwise. The threaded rod 31 rotates in the opposite direction, and the upper and lower threaded sleeves 36 move in opposite directions. The hinge rod 37 pushes the movable plate 38 and the gripper 39 to move in opposite directions. The gripper 39 opens, and the dust cap is removed. After the operation is completed, squeeze the two side blocks 43 to disengage the blocks 43 from the limiting port 45, push the connecting rod 2 down to the initial position until the blocks 43 are engaged in the limiting port 45 at the bottom of the limiting groove 44, and the cap grabber returns to the initial storage state (total length 0.7m), making it easy to put into the tool bag for carrying.

[0038] Implementation effect

[0039] This embodiment achieves flexible adjustment of the cap grabber length through the adjustment component 4, adapting to different height and depth dust cap disassembly scenarios, solving the problem of "fixed length and narrow applicable range" of traditional cap grabbers; the picking component 3 achieves automatic clamping of the gripper 39 through the cooperation of the threaded rod 31 and the threaded sleeve 36, eliminating the need for manual insertion into the branch box to grab, reducing the risk of electric shock and mechanical damage; the setting of the dovetail block 21, dovetail groove 22, and limit telescopic rod 381 ensures stable operation of the device, and the rubber block can effectively protect the surface of the dust cap from scratches, fully meeting the safety and practicality requirements of power maintenance operations.
