Description

Technical Field

[0001] This utility model relates to the field of power facility technology, specifically a rotary power component and a cable stripping device. Background Technology

[0002] During line splicing, stripping the insulation sheath of the conductor is a crucial step in conductor stripping and splicing. To prevent workers from directly contacting live conductors, automated stripping devices are gradually replacing manual stripping. Current automated stripping devices primarily use a drive mechanism to rotate the stripping section, achieving a rotary stripping effect relative to the cable. For the current drive mechanism, to ensure radial insertion of the cable, the main gear is designed as an open-end gear. To meet the requirement of both rotation and an open end, the mainstream approach is to use several drive wheels arranged circumferentially around the main gear and individually meshing with it.

[0003] To optimize the complex drive structure of the multi-drive wheel in the aforementioned drive section, an optimization and improvement scheme for the drive section is described in the text of Chinese Patent Publication No. CN116526375A, entitled "An Adaptive Cable Stripping Tool." Specifically, it involves providing a closed chain block at the opening of the open wheel to avoid the cable installation path when open; when the closed chain block closes the opening, the outer edge of the closed chain block and the outer edge of the open wheel together form a fully circular transmission surface of the drive wheel at the power connection drive source.

[0004] The aforementioned cited patent simplifies the drive structure by eliminating the need for multiple main gears. However, in practice, the hinged nature of the closed chain block causes it to wobble during operation, leading to issues like edge warping and jamming when meshing with the drive wheel. While the cited patent further describes magnetic fixation of the closed chain block when closing the opening, this method, although eliminating the need for an electric drive structure for automatic fixation, is ineffective if the magnetic force is too weak, while excessive force hinders opening the closed chain block during assembly and disassembly. Furthermore, in situations involving cable stripping at heights using magnetic fixation, the stripping device is often fixed to an insulating rod and manually attached to the cable. This process is prone to errors, such as the closing chain block being accidentally closed before the cable enters the inner cavity of the opening wheel. Since the cable has not yet entered the inner cavity of the opening wheel, the closing chain block cannot be opened from the inside out by the force exerted during the separation process of the stripping device from the cable, as is the case under normal attachment. Obviously, in the above-mentioned case of accidental closure, the stripping device needs to be removed and the closing chain block manually opened, which is not convenient enough and therefore urgently needs to be solved. Utility Model Content

[0005] To avoid and overcome the technical problems existing in the prior art, this utility model provides a rotary power component and a cable stripping device. During operation, it has a locking state that keeps the closed chain block in a closed state and stable without shaking, which improves the stability of the open wheel rotation drive. It can also realize the convenient unlocking of the closed chain block when working at height, which improves the fault tolerance rate during the stripping device loading process, thereby improving the convenience of the loading process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary power assembly includes an open wheel rotatably fitted onto a housing and a closed chain block hinged to a first open end of the open wheel, such that the open wheel is in a locked state when it rotates in reverse. The cantilever end of the closed chain block is provided with a stabilizing slider that can elastically slide along the rotation direction of the open wheel. A stabilizing groove is recessed at a second open end along its rotation direction for the stabilizing slider to insert into. An unlocking push block is also provided in the stabilizing groove. A one-way limiting part is provided on the housing to constrain the sliding direction of the unlocking push block, so that when the open wheel rotates forward, the unlocking push block is limited by the one-way limiting part and pushes the stabilizing slider out of the stabilizing groove in the opposite direction.

[0008] As a further embodiment of this utility model: the one-way limiting part includes a swing arm elastically hinged to the housing, and a stop is provided in the elastic return direction of the swing arm, so that when the swing arm travels to the stop due to the elastic action, the swing arm is positioned by the action of the stop; an unlocking slide is provided through the housing at the unlocking push block, and when the open wheel rotates clockwise to unlock the closed chain block, the unlocking slide and the stop clamp the swing arm in the positioned state.

[0009] As a further embodiment of this utility model: the hinge point of the swing arm is located outside the rim of the open wheel, and the elastic reset direction is opposite to the forward rotation direction of the open wheel; along the elastic reset direction, the stop block abuts against the inner side of the swing arm near the hinge point.

[0010] As a further improvement of this invention: a torsion spring is installed at the hinge shaft of the swing arm to form the elastic hinge of the swing arm.

[0011] As a further improvement of this utility model: the open wheel has a guide elongated hole for guiding the sliding direction of the unlocking slide column. When the unlocking slide column is in the unlocked state of pushing the stabilizing slider out of the stabilizing slide groove in the opposite direction, it abuts against the wall of one end of the guide elongated hole in the length direction of the hole. At this time, the opening of the open wheel is aligned with the cable installation channel on the housing.

[0012] As a further improvement of this utility model: the groove length direction of the stabilizing slide is arranged coaxially with the opening wheel, and in the locked state, the sliding direction of the stabilizing slider is also arranged coaxially with the opening wheel.

[0013] As a further embodiment of this utility model: the inner cavity of the cantilever end of the closed chain block has a guide groove, and the stabilizing slider in the locked state is a two-stage stepped rod structure arranged along the length direction of the guide groove. The inner end of the thick rod section of the stabilizing slider slides in the guide groove, and the inner cavity of the stabilizing groove is provided with a compression spring that elastically compresses the inner end of the stabilizing slider.

[0014] As a further improvement of this utility model: a tension spring is arranged in the stabilizing groove to pull the unlocking push block to slide inward and reset.

[0015] A cable stripping device that utilizes a rotary power assembly, including a cutting assembly fixed to an open wheel for cutting the insulation of a cable.

[0016] As a further embodiment of this utility model, it also includes a clamping component for centering and clamping the cable, which is disposed on the open wheel, and the clamping center of the clamping component is coaxial with the rotation center of the open wheel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Based on the stable locking formed by the automatic insertion of the stabilizing slider into the stabilizing groove when the closed chain block is closed, the stabilizing groove is also equipped with an unlocking push block. The housing is provided with a one-way limiting part for constraining the sliding direction of the unlocking push block, so that when the opening wheel rotates forward, the unlocking push block is limited by the one-way limiting part and pushes the stabilizing slider out of the stabilizing groove in the opposite direction.

[0019] Therefore, when the open wheel is reversed for normal operation (such as cable stripping or de-icing), the one-way limiting part will not push the unlocking push block to slide. After normal operation is completed, the open wheel only needs to rotate forward, and the unlocking push block, limited by the one-way limiting part, will push the stabilizing slider out of the stabilizing groove in the opposite direction, thereby unlocking the closed chain block. Thus, even if the closed chain block is accidentally closed due to operational error during high-altitude operations, it can be unlocked directly at high altitude without having to remove the device from the height, unlock it, and then lift it back up. This ensures convenient unlocking of the closed chain block and improves the ease of installation by increasing the fault tolerance during device installation.

[0020] 2. The push part adopts a swing arm swing avoidance form. Compared with the linear stroke one-way stop structure similar to the door lock cylinder, the protruding part pushes the swing arm to swing avoid, which is more labor-saving.

[0021] 3. After the opening wheel of this application reverses to perform operations such as cable stripping or de-icing, it only needs to be positioned by the guide hole behind the opening wheel to stop its rotation and reach its limit position. At this time, the closing chain block automatically unlocks, and the opening of the opening wheel aligns with the cable installation channel on the housing, thus detaching the application from the cable. This eliminates the need to observe the relative position of the opening and the cable channel using a camera during disassembly, or to use sensors for precise alignment control of the opening and the cable channel during high-altitude operations. Simultaneously, because the unlocking push block prevents the stabilizing slider from inserting into the stabilizing groove in this state, the closing chain block will not accidentally close due to operational errors during complex high-altitude loading operations, ensuring convenient unlocking of the closing chain block.

[0022] 4. The length of the stabilizing slide is coaxial with the opening wheel. In the locked state, the sliding direction of the stabilizing slider is also coaxial with the opening wheel. With this arrangement, the force direction of the unlocking push block and the stabilizing slider is basically consistent with the sliding direction, reducing the resistance during the sliding process of the unlocking push block and the stabilizing slider.

[0023] 5. A tension spring is arranged inside the stabilizing groove to pull the unlocking push block to slide inward and reset, so that the unlocking push block is located inside the stabilizing groove to avoid the stabilizing slider under normal conditions, thereby reducing the frictional resistance when the stabilizing slider is inserted into the stabilizing groove from the outside to the inside.

[0024] 6. The rotary power assembly of this application has high versatility and can be adapted to cable stripping devices or wrap-around cable outer wall foreign object cleaning devices and wrap-around de-icing devices. Attached Figure Description

[0032] 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.

[0033] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0034] The main structure of the rotary power assembly 20 of this utility model is as follows: Figure 1-5 As shown, the main structure of the rotary power assembly 20 includes an open wheel 22 rotatably fitted onto the housing 10 and a closed chain block 23 hinged to the first end of the open portion of the open wheel 22, so that the open wheel 22 is in a locked state when it reverses. In practice, the open wheel 22 is driven to rotate by a power source 21 arranged on the housing 10. Specifically, the power source 21 can be a drive wheel that meshes with the open wheel 22, and the drive wheel can be directly connected to a motor, or it can transmit power to the motor output shaft through a reducer or belt.

[0035] The above structure is prior art as cited in the patent; its working principle is explained below:

[0036] In the initial state, the opening of the open wheel 22 is aligned with the cable mounting channel on the housing 10, allowing the cable to enter the inner cavity of the cable mounting channel through the opening for installation. Subsequently, under the action of the power source 21, the open wheel 22 is driven to rotate in reverse (when rotating in reverse, along the direction of rotation, the hinge end of the closed chain block 23 is in front and the cantilever end is behind, and this direction of rotation is reverse rotation; similarly, the direction opposite to the direction of rotation is forward rotation), thereby causing the closed chain block 23 to close the opening of the open wheel 22 under its own gravity rotation and / or the obstruction of the housing 10, so as to achieve continuous rotational drive of the open wheel 22 and the closed chain block 23 as a whole, thereby driving the cutting assembly 30 and the clamping assembly 40 to produce synchronous rotational movements.

[0037] Based on the above, such as Figure 2As shown, the cantilever end of the closed chain block 23 is provided with a stabilizing slider 232 that can elastically slide along the rotation direction of the open wheel 22, and the second end of the open portion is recessed along its rotation direction with a stabilizing groove 221 into which the stabilizing slider 232 can be inserted. Preferably, the insertion end of the stabilizing groove 221 into which the stabilizing slider 232 is inserted has a chamfered structure or a wedge-shaped structure, so that when the closed chain block 23 is closed, the stabilizing slider 232 can be quickly and automatically inserted into the stabilizing groove 221; specifically, this structure can be referred to as the one-way closing structure of a door lock.

[0038] Based on the above-mentioned stable locking formed by the automatic insertion of the stabilizing slider 232 into the stabilizing groove 221 when the closed chain block 23 is closed, the unlocking of the stabilizing slider 232 is further optimized below.

[0039] like Figure 2 As shown, the stabilizing groove 221 is also equipped with an unlocking pusher 222, and the housing 10 is provided with a one-way limiting part for constraining the sliding direction of the unlocking pusher 222, so that when the opening wheel 22 rotates forward, the unlocking pusher 222 is limited by the one-way limiting part and pushes the stabilizing slider 232 out of the stabilizing groove 221 in the opposite direction. Therefore, when the opening wheel 22 rotates in reverse for normal operation (such as cable stripping or de-icing), the one-way limiting part will not push the unlocking pusher 222 to slide; and after the normal operation is completed, as long as the opening wheel 22 rotates forward, the unlocking pusher 222 is limited by the one-way limiting part and pushes the stabilizing slider 232 out of the stabilizing groove 221 in the opposite direction, thereby unlocking the closed chain block 23. Therefore, even if the closed chain block 23 is accidentally closed due to operational error during high-altitude operations, it can be unlocked directly at high altitude without having to remove the device from the high altitude, unlock it, and then lift it to a high place. This ensures convenient unlocking of the closed chain block 23, thereby improving the convenience of the mounting process by increasing the fault tolerance rate during device mounting.

[0040] Specifically, such as Figure 4 and Figure 5 As shown, the one-way limiting part includes a rocker arm 24 elastically hinged to the housing 10. A stop 242 is provided in the elastic return direction of the rocker arm 24, so that when the rocker arm 24 travels to the stop 242 due to elastic action, the rocker arm 24 is positioned by the action of the stop 242. An unlocking slide 223 is provided through the housing 10 at the unlocking push block 222. When the open wheel 22 rotates clockwise to unlock the closed chain block 23, the unlocking slide 223 and the stop 242 clamp the rocker arm 24 in the positioned state.

[0041] When the open-end wheel 22 reverses to perform normal operation, such as Figure 3 As shown in state a, after the unlocking slider 223 comes into contact with the swing arm 24, the swing arm 24 will swing to avoid the unlocking slider 223; and when the unlocking slider 223 and the swing arm 24 are misaligned, as... Figure 3 As shown in state b, when the rocker arm 24 travels to the stop 242 due to its elasticity. And when the open wheel 22 rotates clockwise to unlock, as... Figure 3 As shown in state c, the unlocking slide 223 and the stop 242 clamp the swing arm 24, which is in the positioning state, towards each other. As the unlocking slide 223 continues to rotate clockwise, as... Figure 3 As shown in state d, the rocker arm 24 is limited due to the obstruction of the stop block 242. Under the action of this limit, the unlocking push block 222 can only slide outward, thereby generating a sliding action that pushes the stabilizing slider 232 out of the stabilizing groove 221 in the opposite direction.

[0042] Furthermore, such as Figure 5 As shown, the hinge point of the swing arm 24 is located outside the rim of the open wheel 22, and the elastic reset direction (i.e., the rotation direction of the swing arm 24 during elastic reset) is opposite to the forward rotation direction of the open wheel 22. Along the elastic reset direction, the stop block 242 abuts against the inner side of the swing arm 24 near the hinge point. This arrangement reduces interference with the inner space of the open wheel 22. Of course, if the internal space of the open wheel 22 is sufficient to avoid the swing path of the swing arm 24, the hinge point of the swing arm 24 can be located outside the rim of the open wheel 22, and correspondingly, the elastic reset direction is in the same direction as the forward rotation direction of the open wheel 22.

[0043] Based on the above, a torsion spring 241 is installed at the hinge axis of the rocker arm 24 to form an elastic hinge of the rocker arm 24. The torsion spring 241, as an elastic component, significantly reduces the space occupied. In actual implementation, if space is sufficient, a spring or sheet spring can also be used to drive the rocker arm 24 to rotate around the elastic return point to abut against the stop block 242.

[0044] In practical implementation, the one-way limiting part can also adopt a linear one-way limiting structure similar to that of a door lock cylinder. That is, when rotating in reverse, the unlocking slide 223 and the lock cylinder structure are misaligned with the wedge, while when rotating in the forward direction, the lock cylinder structure limits the swing rod 24. However, this implementation method occupies less space during the process compared to the swing rod 24 swinging and avoiding form, but the swing rod 24 swings and avoids form with less effort.

[0045] Specifically, such as Figure 3-5As shown, the open wheel 22 has a guide elongated hole 225 for guiding the sliding direction of the unlocking slide 223. When the stabilizing slider 232 is pushed out of the stabilizing groove 221 in the opposite direction and unlocked, the unlocking slide 223 abuts against one end wall of the guide elongated hole 225 along its length. At this time, the opening of the open wheel 22 is aligned with the cable mounting channel on the housing 10. The structural arrangement of the guide elongated hole 225 limits the extreme position of the unlocking slide 223 to slide outward. That is, when the open wheel 22 rotates forward, the pushing part pushes the unlocking slide 223 to slide to the unlocked state, thereby stopping the forward rotation of the open wheel 22. Subsequently, after the opening wheel 22 of this application strips the cable by rotating around the working direction, it only needs to rotate around the unlocking direction and use the guide elongated hole 225 to position the unlocking slide 223, thus stopping the rotation of the opening wheel 22 and positioning it to the limit position. At this time, the closing chain block 23 automatically unlocks, and the opening of the opening wheel 22 aligns with the cable installation channel on the housing 10, realizing the disassembly of this application from the cable. This eliminates the need to observe the relative position of the opening and the cable channel with a camera during disassembly, or to use sensors to achieve precise control of the alignment of the opening and the cable channel during high-altitude operations. At the same time, since the unlocking push block 222 prevents the stabilizing slider 232 from inserting into the stabilizing slide groove 221 in this state, the closing chain block 23 will not be accidentally closed due to operational errors during the complex loading process of the device at height, ensuring the convenient unlocking of the closing chain block 23.

[0046] Based on the above, the preferred option is, for example... Figure 2 As shown, the groove length of the stabilizing groove 221 is coaxially arranged with the opening wheel 22 (the arc formed by the groove length of the stabilizing groove 221 coincides with the center of the opening wheel 22). In the locked state, the sliding direction of the stabilizing slider 232 is also coaxially arranged with the opening wheel 22 (the center of the sliding trajectory of the stabilizing slider 232 coincides with the center of the opening wheel 22). With this arrangement, the force direction of the unlocking push block 222 and the sliding direction of the stabilizing slider 232 are basically consistent with the sliding direction, reducing the resistance during the sliding process of the unlocking push block 222 and the stabilizing slider 232.

[0047] Furthermore, as shown in Figure 2, the inner cavity of the cantilever end of the closed chain block 23 has a guide groove 231, and the inner cavity of the stabilizing groove 221 is provided with a compression spring 233 that elastically compresses the inner end of the stabilizing slider 232. In the locked state, the stabilizing slider 232 is a two-stage stepped rod-like structure arranged along the length of the guide groove 231. The inner end of the thicker rod section of the stabilizing slider 232 slides within the guide groove 231, allowing the stabilizing slider 232 to achieve sliding engagement with the guide groove 231 without falling off. Of course, in actual implementation, the stabilizing slider 232 can also be fixed to a telescopic rod with a spring installed on it. More preferably, in this embodiment, the telescopic rod's extension direction is coaxial with the open wheel 22, meaning the center of the trajectory in the extension direction coincides with the center of the open wheel 22.

[0048] Based on the above, such as Figure 1 As shown, a tension spring 224 is arranged inside the stabilizing groove 221 to pull the unlocking push block 222 to slide inward and reset. The arrangement of the tension spring 224 ensures that the unlocking push block 222 is normally located inside the stabilizing groove 221, avoiding the stabilizing slider 232, thereby reducing the frictional resistance when the stabilizing slider 232 is inserted into the stabilizing groove 221 from the outside to the inside.

[0049] In practice, the aforementioned rotary power assembly 20 can be used in a cable stripping device.

[0050] Among them, such as Figure 1 As shown, the cable stripping device includes a cutting component 30 mounted on a rotary power assembly 20 and rotating with the rotary power assembly 20 to cut the insulation of the cable. The cutting component 30 is the same as that in the cited patent and has an adjustment function, which enables stripping of cables of different diameters. This is prior art and will not be described in detail.

[0051] The cable stripping device also includes a clamping assembly 40 for centering and holding the cable, wherein the clamping center of the clamping assembly 40 is coaxial with the rotation center of the open wheel 22, which can be used to keep the rotating power assembly 20 coaxial with the cable during different cable stripping processes. The specific structure is described in the prior art of the cited patent, and will not be repeated here.

[0052] Of course, in further implementation, the rotary power assembly 20 of this application can also be used in conjunction with other devices for power facility operations. For example, when cleaning foreign objects or de-icing the outer wall of a cable, if a rotational operation around the cable is adopted, the power assembly driving the foreign object cleaning cutter or de-icing blade can be replaced with the rotary power assembly 20 of this application.

[0053] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
