For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0023] Please see Figure 1 and Figure 2 The present application provides an arm-mounted grounding wire installation auxiliary device, which includes: an arm assembly 10 and a clamping assembly 20.
[0024] The hanging arm assembly 10 includes: an inner support frame 11 and a fastener 12; the fastener 12 is disposed on the inner support frame 11.
[0025] In this embodiment, the binding member 12 can be a cable tie, and a fixing buckle is provided on the binding member 12. The fixing buckle can be an existing structure that can be quickly connected with the cable tie. Through the cooperation of the fixing buckle and the cable tie, the binding member 12 can be quickly and securely bound. Specifically, the binding member 12 can be bound to the worker's arm to realize the connection between the inner support frame 11 and the worker's arm.
[0026] The clamping assembly 20 includes: a first semicircular ring 21, a second semicircular ring 22, and an outer support frame 23; the outer support frame 23 is disposed on the inner support frame 11; a first motor 211 and a first transmission belt 212 are disposed on the first semicircular ring 21; a second motor 221 and a second transmission belt 222 are disposed on the second semicircular ring 22; the first motor 211 is driven to the first transmission belt 212; the second motor 221 is driven to the second transmission belt 222; the first semicircular ring 21 and the second semicircular ring 22 are both openable and closable on the outer support frame 23, and the two form a clamping cavity; when the clamping cavity clamps the object, the first transmission belt 212 and the second transmission belt 222 respectively abut against the two sides of the object and can drive the object to rotate.
[0027] In this embodiment, both the first semicircular ring 21 and the second semicircular ring 22 are semicircular annular structures. They can be combined to form a circular ring and can also rotate around their respective first ends to open the clamping cavity. When the clamping cavity is open, the object to be clamped can be placed inside. The object to be clamped can be, for example, an insulating rod, specifically a rotating handle on the insulating rod used to drive the inner rod to rotate. When the first semicircular ring 21 and the second semicircular ring 22 are closed, the first transmission belt 212 and the second transmission belt 222 are respectively in close contact with both sides of the object to be clamped. At this time, starting the first motor 211 and the second motor 221 can drive the two transmission belts to start and drive the rotating handle to rotate.
[0028] In practical applications, the hanging arm assembly 10 is secured to the worker's first arm via the binding member 12, specifically located on the inside of the worker's arm, so that the clamped insulating rod is positioned in the worker's palm. The worker then places the insulating rod into the clamping cavity, where it is clamped by the first semi-circular ring 21 and the second semi-circular ring 22. At this point, the worker's first arm can grip the outer rod of the insulating rod. Subsequently, the worker's second hand controls the first motor 211 and the second motor 221 to start, thereby controlling the relative rotation of the inner and outer rods of the insulating rod to tighten the clamping opening and secure the grounding wire. The method by which the worker controls the first motor 211 and the second motor 221 to start can be, for example, by installing a switch on the outer support frame 23 to control their start and stop. The principle of controlling the motors' start and stop via a switch is existing technology and will not be elaborated upon in this embodiment.
[0029] In this way, after clamping the rotating handle of the insulating rod during operation, the worker can simply hold the outer rod without having to rotate the handle, which reduces hand strain, avoids hand pain caused by prolonged work, and reduces the risk of the insulating rod falling off. Furthermore, the combination of a motor and a transmission belt improves the efficiency of controlling the insulating rod.
[0030] In application, the first motor 211 and the second motor 221 can be the same motor, that is, the first transmission belt 212 and the second transmission belt 222 can be connected by one motor at the same time, for example by the transmission shaft of the two transmission belts meshing with gears at the same time.
[0031] As one implementation, elastic friction pads may be provided on the outer periphery of the first transmission belt 212 and the second transmission belt 222 to increase the friction between them and the rotating handle and to ensure the clamping effect of them on the rotating handle.
[0032] It should be noted that during the operation, since the worker holds the outer rod of the insulating rod, the main weight of the insulating rod will not be applied to the clamping assembly 20. Therefore, the output power of the motor on the clamping assembly 20 only needs to meet the load requirement of driving the rotating handle to rotate.
[0033] Generally, the outer periphery of the rotating handle of the insulating rod is provided with friction texture. When the outer periphery of the rotating handle abuts against the transmission belt, the outer surface of the transmission belt can be configured with a structure that matches the friction texture, such as an uneven texture, to enhance the fit between the transmission belt and the rotating handle. Meanwhile, in the embodiments provided in this application, both the first transmission belt 212 and the second transmission belt 222 are elastic and deformable to adapt to and fit the rotating handle.
[0034] In one embodiment, see Figures 1 to 4The inner support frame 11 is provided with a hanging ring 13; the outer support frame 23 is provided with a sliding groove 231; the hanging ring 13 is slidably disposed in the sliding groove 231 so that the outer support frame 23 can be adjusted along the hanging ring 13.
[0035] After the worker's arm is secured by the binding member 12, the hanging ring 13 is correspondingly fixed to the arm. At this time, the outer support frame 23 can move along the hanging ring 13 through the slide groove 231 to adjust the relative position of the clamping assembly 20 and the worker's arm, so as to adapt to different work requirements and ensure operational flexibility and comfort.
[0036] In one implementation, the outer support frame 23 can be adjusted in position along the hanging ring 13, for example, by providing a screw-on wing bolt on the outer support frame 23; when the wing bolt is loosened, the outer support frame 23 can slide relative to the hanging ring 13 to adjust its position; when the wing bolt is tightened, the wing bolt passes through the outer support frame 23 and abuts against the hanging ring 13. The outer support frame 23 is fixedly connected to the hanging ring 13, at which point the relative positions of the clamping assembly 20 and the hanging arm assembly 10 are fixed.
[0037] In one embodiment, the hanging ring 13 is arc-shaped, specifically a semi-circular ring, so that the hanging ring 13 can fit the worker's arm; limit blocks 131 are provided at both ends of the hanging ring 13; a locking block 232 is provided in the slide groove 231; the locking block 232 is used to restrict the limit block 131 from passing through.
[0038] During assembly, after the hanging ring 13 is inserted into the slide groove 231, the two ends of the hanging ring 13 cannot slide out of the slide groove 231 through the cooperation of the limiting block 131 and the locking block 232, thereby ensuring that the hanging ring 13 moves stably in the slide groove 231 and avoiding accidental fall-off.
[0039] In practical applications, the locking block 232 can be machined within the slide groove 231 during processing. The limiting block 131 can be fixed to both ends of the hanging ring 13 by means of bonding, welding, or other methods after the hanging ring 13 is inserted into the slide groove.
[0040] In one embodiment, the slide 231 is a C-shaped groove that opens to the side, which facilitates the processing of the slide 231.
[0041] In one embodiment, the outer support frame 23 is provided with a plurality of elastic locking members 233 extending into the sliding groove 231; the hanging ring 13 is provided with a plurality of locking grooves 132; the elastic locking members 233 are engaged with the locking grooves 132.
[0042] Please see Figure 4 The elastic locking component 233 can be an elastic ball set on the spring; the elastic locking component 233 can be locked into the locking groove 132 to play an auxiliary positioning role for the hanging ring 13 and the outer support frame 23.
[0043] In application, multiple elastic locking components 233 and locking slots 132 can be set, and they correspond one-to-one.
[0044] In one embodiment, a plurality of first drive shafts 213 are provided on the first semicircular ring 21; a plurality of second drive shafts 223 are provided on the second semicircular ring 22; a first drive belt 212 is wound around the plurality of first drive shafts 213; a second drive belt 222 is wound around the plurality of second drive shafts 223; a first motor 211 is drivenly connected to the first drive shafts 213; and a second motor 221 is drivenly connected to the first drive shafts 213.
[0045] In this embodiment, the first motor 211 and the second motor 221 can be connected to the first drive shaft 213 and the second drive shaft 223 respectively via gears or other transmission components. The first drive shaft 213 is connected to the first drive belt 212; the second drive shaft 223 is connected to the second drive belt 222.
[0046] In one implementation, multiple first transmission belts 212 can be arranged on the outer support frame 23 along the axial direction of the first transmission shaft 213; multiple second transmission belts 222 can be arranged along the axial direction of the second transmission shaft 223 to achieve multi-point contact of the rotating handle along the axial direction, thereby improving transmission efficiency and stability, and ensuring smoothness and reliability during operation.
[0047] In one embodiment, the first transmission belt 212 is wound in a semi-circular shape on a plurality of first transmission shafts 213; the second transmission belt 222 is wound in a semi-circular shape on a plurality of second transmission shafts 223; the diameter sides of the first transmission belt 212 and the second transmission belt 222 are used to clamp the clamped object.
[0048] The semi-circular first drive belt 212 and second drive belt 222 have larger buffer areas, enabling them to clamp insulating rods of different sizes.
[0049] In one embodiment, the inner ends of the first semicircular ring 21 and the second semicircular ring 22 are provided with a rebound spring 24; the rebound spring 24 is used to provide an elastic force to the first semicircular ring 21 and the second semicircular ring 22 to move in the opening direction; the outer end of the first semicircular ring 21 is provided with a buckle 25; the outer end of the second semicircular ring 22 is provided with a slot 26; the buckle 25 is used to engage with the slot 26.
[0050] Among them, the rebound spring 24 can be a torsion spring; the inner ends of the first semicircular ring 21 and the second semicircular ring 22 can both be rotatably mounted on the central shaft; the rebound spring 24 is mounted on the central shaft.
[0051] When the buckle 25 engages with the slot 26, the first semicircular ring 21 and the second semicircular ring 22 can be kept in a closed state. Correspondingly, a storage slot 28 for storing the buckle 25 can be provided on the first semicircular ring 21.
[0052] In one embodiment, the outer support frame 23 is provided with a connecting plate 27 that can be adjusted in position; the first semicircular ring 21 and the second semicircular ring 22 are both openable and closable on the connecting plate 27.
[0053] With the axial direction of the insulating rod as the vertical direction, in this embodiment, after clamping the insulating rod, the connecting plate 27 can adjust the position of the outer support 23 in the vertical direction, thereby adjusting the distance between the insulating rod and the worker's palm to ensure operational comfort and safety.
[0054] In one embodiment, the outer support frame 23 is provided with a second slide groove 234; the second slide groove 234 is arranged in a vertical direction; the connecting plate 27 is provided with a first slider 271 and a second slider 272; the second slider 272 is rotatably connected to the connecting plate 27; both the first slider 271 and the second slider 272 are slidably disposed in the second slide groove 234; the first slider 271 can slide out of the second slide groove 234; both ends of the second slide groove 234 are provided with limiting members to restrict the second slider 272 from sliding out.
[0055] Specifically, the second slider 272 may be provided with a rotating block 274; the rotating block 274 is connected to the second slider 272 through a pin 273, and the rotating block 274 is placed in the second slide groove 234, so that the second slider 272 can rotate relative to the outer support frame 23.
[0056] After the first slider 271 and the second slider 272 have both slid into the second groove 234, the bottom of the second groove 234 can be sealed by a sealing block, preventing the first slider 271 and the second slider 272 from sliding out from the bottom of the second groove 234. Simultaneously, the first slider 271 and the second slider 272 can be T-shaped blocks, preventing them from leaving the second groove 234 in a direction perpendicular to the plane of the second groove 234. The top of the second groove 234 has an opening configured to allow the first slider 271 to slide out while restricting the second slider 272 from sliding out; for example, the inner diameter of the opening can be set to be larger than the outer diameter of the first slider 271 but smaller than the outer diameter of the second slider 272. Therefore, the first slider 271 can slide out of the second groove 234 from the top. After the first slider 271 slides out, the connecting plate 27 can rotate around the pin 273 to further adjust the relative position of the clamped insulating rod and the worker's arm, thereby achieving more flexible adjustment.
[0057] As one implementation, a second elastic post 235 may be provided in the second slide groove 234; the second elastic post 235 can engage with the first slider 271 or the second slider 272 when the first slider 271 or the second slider 272 is positioned, thereby playing an auxiliary positioning role.
