Description

Technical Field

[0001] The invention relates to the field of auxiliary tools for wire grippers, and in particular to an auxiliary tool for wire grippers. Background Art

[0002] With the rapid growth of social economy, the power industry has developed vigorously, which has also led to the continuous expansion of the construction scale of distribution networks and the continuous upgrading and transformation of rural distribution networks.

[0003] In daily distribution line construction work, especially the tightening work of 10kV and 0.4kV overhead lines in rural power grids, the following problems are often encountered: before tightening the line, the installation distance of the wire clamp is not enough to tighten the wire; after tightening the line, the wire clamp is far away from the operator, making it difficult to remove the wire clamp or it is difficult to remove the wire clamp.

[0004] The current solutions are: first, repeatedly install the wire clamp and tighten the wire several times, then temporarily install the wire on the cross arm, move the wire clamp again and tighten the wire until the wire is tightened to meet the requirements, and then install the wire clamp; second, when the wire clamp cannot be removed or it is difficult to remove the wire clamp after the wire is tightened, use a rope or other temporary tools on site to remove the wire clamp. Both situations affect the operation cycle and there are situations such as non-standard operations.

[0005] A Chinese patent (publication number: CN204354053U) discloses an auxiliary tool for a wire clamp, including a push rod and a sleeve sleeved on the push rod; a handle is provided at the front end of the push rod; a handle is provided at the front end of the sleeve; a baffle is provided at the end of the sleeve, and a spring is provided between the baffle and the push rod; a slit is opened on the sleeve; a rear stop rod is fixedly connected to the sleeve, and a front stop rod is fixedly connected to the push rod, and the front stop rod passes through the slit.

[0006] The above scheme realizes the relative movement of the front and rear gear levers by the relative movement of the handle and the lever, so that the wire holder tightens or loosens the cable; the wire holder is pushed to a distant place or retrieved by the push rod, and the rod is used to hook the parts on the wire holder for operation. On the one hand, the operator needs to align with the corresponding position, which is quite difficult. On the other hand, the operation using the gear lever is unstable. The wire holder can easily detach from the gear lever and the operator needs to adjust the position many times, which reduces the operator's work efficiency and increases the difficulty of the operator's work.

DETAILED DESCRIPTION

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1

[0049] In the prior art, in daily distribution line construction work, especially the tightening work of 10kV and 0.4kV overhead lines in rural power grids, the problem of insufficient installation distance of the wire clamp before tightening the wire is often encountered.

[0050] The present invention provides an auxiliary tool for a wire clamp, such as Figure 1-3 As shown, including:

[0051] Support rod 1, in this embodiment, support rod 1 is a straight rod, and the straight rod is made of stainless steel, which increases the hardness and strength of the overall skeleton. In addition, the shape of the straight rod can be square or cylindrical.

[0052] Specifically, the support rod 1 is provided with a first placement groove and a second placement groove which are distributed up and down and are used for placing the first telescopic structure 3 and the second telescopic structure 5 respectively. The first placement groove and the second placement groove may be hole grooves or square grooves.

[0053] The first operating part 2 is installed at one end of the support rod 1 through the first telescopic structure 3. The first telescopic structure 3 can make up for and increase the total length of the support rod 1, so as to facilitate the contact between the auxiliary tool and the wire clamp. Specifically, the first telescopic structure 3 includes a first sleeve and a second sleeve that are slidably connected. The second sleeve is located inside the first sleeve. When the second sleeve is extended, the first sleeve and the second sleeve can be fixed by rotating with a thread. Specifically, the inner end of the first sleeve is provided with an external thread, and the outer end of the first placement groove is provided with an internal thread, so that when the first sleeve is extended, the first sleeve and the first placement groove are fixed by threaded cooperation. In addition, the second sleeve is limitedly engaged with the first placement groove through a clamping block. Specifically, the clamping block is elastically connected to the outer end of the first sleeve, and a clamping groove is provided at the outer end position of the first placement groove. The clamping groove is connected with the clamping block to retract the second sleeve and limit the free sliding of the first sleeve and the second sleeve. The other two sleeves can also be fixed by telescopic means such as clamping holes and elastic protrusions.

[0054] The first operating part 2 includes a hook 21, which is engaged with the wire gripper. After being extended and retracted, the first operating part 2 is clamped on the pressure plate, so that the operator can operate or retrieve the wire gripper from a long distance.

[0055] The second operating part 4 is mounted on one end of the support rod 1 through the second telescopic structure 5, and is used to loosen the wire clamp. Like the first telescopic structure 3, the second telescopic structure 5 also includes two sleeves, and the specific structure is the same as the first telescopic structure 3.

[0056] Currently common cable clamps generally include an upper clamping plate, a lower clamping plate, a pressure plate and a pull plate; the cable is placed in the clamping hole between the upper clamping plate and the lower clamping plate, one end of the upper clamping plate is rotatably connected to the lower clamping plate, the other end of the upper clamping plate is rotatably connected to the pressure plate, one end of the pressure plate is rotatably connected to the lower clamping plate, the other end of the pressure plate is rotatably connected to one end of the pull plate, and the other end of the pull plate is slidably connected to the lower clamping plate through a connecting shaft.

[0057] It can be known that when force acts on the pressure plate on the cable clamp and moves away from the pull plate, the pressure plate will rotate, and the pull plate will slide on the lower clamp plate and the upper clamp plate will rotate and separate from the lower clamp plate, thereby properly loosening the cable. When force acts on one end of the lower clamp plate and cooperates with the pressure plate, the cable clamp can easily loosen the cable and retract it.

[0058] Based on this, the functions of the first operating part 2 and the second operating part 4 are independent of each other. When the wire holder is moved and installed, the operation is completed using the first operating part 2 with a single auxiliary tool. When retrieving the wire holder, two auxiliary tools are used, one of which uses the first operating part 2 to clamp against the pressure plate on the wire holder, and the other uses the second operating part 4 to clamp against the lower clamp on the wire holder. The first operating part 2 is pushed outward, and the second operating part 4 is pulled inward. The wire holder is loosened by pushing and pulling and is retrieved by the second operating part 4.

[0059] Further, if Figure 2 As shown, the hook 21 is a U-shaped structure that is shorter at the top and longer at the bottom, and the U-shaped structure faces away from the handle 6 .

[0060] Specifically, the U-shaped structure of the hook 21 is clamped on the pressure plate, and the U-shaped structure of the hook 21 faces the pressure plate and cooperates. Then the operator applies force to push the hook 21 and drive the pressure plate on the wire clamp to move, and the wire clamp is slightly loosened and moves. In addition, the hook 21 is set to be short at the top and long at the bottom, so that the hook 21 is not easy to separate from the pressure plate, so that the wire clamp can be continuously and stably pushed to move in the direction away from the operator to a suitable installation position.

[0061] Further, the tail end of the handle 6 is provided with a suspension ring 8. The suspension ring 8 has a diameter of 50 mm, which is convenient for hanging or lifting when working on the pole, thereby not affecting other operations of the operator at high altitude.

[0062] Furthermore, a rubber sleeve 7 is provided on the handle 6, and stripes are provided on the rubber sleeve 7. Usually, the operator needs to hold the handle 6 to operate the wire clamp, and the setting of the rubber sleeve 7 increases the comfort of holding. In addition, the stripes can increase the friction between the operator and the rubber sleeve 7 to prevent the operator from slipping and causing safety hazards.

[0063] Example 2

[0064] In addition, the first operating portion 2 is not limited to the form of the hook 21. In order to further strengthen the abutment and fixation between the first operating portion 2 and the wire gripper, it is convenient to push the wire gripper to a suitable installation position, such as Figure 4 As shown, the hook 21 can be replaced by a locking member, which includes a first claw 22, a second claw 23, a connecting block 24 and a self-locking portion 25.

[0065] The first clamping claw 22 and the second clamping claw 23 are symmetrically arranged, and the first clamping claw 22 and the second clamping claw 23 are hinged by the first rotating shaft 26 to form an inner clamping space and an outer clamping space; wherein the first clamping claw 22 and the second clamping claw 23 are both arc-shaped, and the inner clamping space is located in the outer clamping space.

[0066] The connecting block 24 is connected to the first telescopic structure 3 and to the first rotating shaft 26, and is used to support the first claw 22 and the second claw 23; in this embodiment, the connecting block 24 plays a connecting role. On the one hand, it ensures the support of the first rotating shaft 26 and the normal operation of the first claw 22 and the second claw 23. On the other hand, it adapts to the connection of the first telescopic structure 3 to ensure the normal telescopic operation.

[0067] The self-locking portion 25 is installed between the first claw 22 and the second claw 23 to control the direction of the first claw 22 and the second claw 23 .

[0068] Specifically, the first clamping claw 22 and the second clamping claw 23 begin to approach the pressing plate, the pressing plate extends into the outer clamping space and contacts the inner clamping space, and then the pressing plate enters the inner clamping space under the action of the resisting force. In this process, the first clamping claw 22 and the second clamping claw 23 move relative to each other. To adapt to the size of the pressing plate, the inner clamping space becomes larger to accommodate the entry of the pressing plate, and the outer clamping space becomes smaller and closes to clamp the pressing plate again. Finally, under the action of the self-locking part 25, the first clamping claw 22 and the second clamping claw 23 maintain the clamping state, thereby ensuring that the first clamping claw 22 and the second clamping claw 23 can stably clamp the pressing plate.

[0069] The self-locking part 25 includes a ratchet 251, a rotating rod 252 and a pawl 253.

[0070] The ratchet 251 is sleeved on the first rotating shaft 26 and fixedly connected to the first claw 22; Figure 4 As shown, specifically, the first pawl 22 and the ratchet 251 are fixedly sleeved on the first rotating shaft 26, and the second pawl 23 is rotationally connected to the first rotating shaft 26, so that it can be known that the ratchet 251 and the first pawl 22 rotate with the rotation of the rotating shaft, and the second pawl 23 rotates on the first rotating shaft 26. In addition, the rotating rod 252 is arranged on the second pawl 23; the pawl 253 is rotationally connected to the rotating rod 252 and cooperates with the ratchet 251. The rotating rod provides support for the pawl 253 and ensures the stable cooperation between the pawl 253 and the ratchet 251. It can be seen from the figure that the locking of the ratchet 251 and the pawl 253 does not affect the normal rotation of the first pawl 22 and the second pawl 23, and at the same time ensures the normal self-locking.

[0071] Specifically, the ratchet 251 is a wheel-type component with a toothed surface or a friction surface, and a torsion spring is connected between the pawl 253 and the rotating rod 252, so that the pawl 253 can be stuck in and slide out of the tooth groove of the ratchet 251 while preventing the ratchet 251 from rotating in the opposite direction to clamp the ratchet 251, so that the ratchet 251 can move in one direction.

[0072] Specifically, the working principle of the self-locking part 25 is:

[0073] The first pawl 22 and the second pawl 23 both rotate around the first rotating shaft 26. During the rotation, since the ratchet 251 is concentrically arranged with the first rotating shaft 26, the ratchet 251 rotates driven by the first pawl 22, and the second pawl 23 drives the pawl 253 to rotate around the first rotating shaft 26 (i.e., the pawl 253 rotates around the ratchet 251) so that the pawl 253 stably moves on the ratchet 251. After stopping, the first pawl 22 and the second pawl 23 cannot rotate reversely under the cooperation of the ratchet 251 and the pawl 253, and thus the pressure plate can be stably clamped between the first pawl 22 and the second pawl 23.

[0074] Finally, in order to prevent the first clamping claw 22 and the second clamping claw 23 from damaging the wire gripper, the first clamping claw 22 and the second clamping claw 23 are both covered with soft pads to prevent the first clamping claw 22 and the second clamping claw 23 from having hard contact with the wire gripper.

[0075] Since the first clamping claw 22 and the second clamping claw 23 can be automatically locked, the first clamping claw 22 and the second clamping claw 23 can be stably matched with any suitable position of the pressure plate on the wire clamp, avoiding the need for the operator to perform multiple alignment operations, reducing the difficulty of the operator's work and alleviating the burden.

[0076] Example 3

[0077] In the prior art, the wire gripper is often far away from the operator after the wire tightening operation, and it is easy to have the problem of difficulty in removing the wire gripper.

[0078] In order to solve the above problem, the present invention provides another implementation method. Specifically, when the wire gripper needs to be retrieved, the auxiliary tools in the two fundamental solutions are used to drive the wire gripper to loosen the wire and then retrieve it.

[0079] Specifically, one of the auxiliary tools extends out of the first operating part 2 through the first telescopic structure 3, and the other auxiliary tool extends out of the second operating part 4 through the second telescopic structure 5. At this time, the first operating part 2 is used to cooperate with the pressure plate to clamp and push it away from the handle 6, and the second operating part 4 is used to cooperate with the lower clamping plate to clamp and pull it toward the handle 6. Through the form of pushing and pulling, the wire clamp is opened to loosen the wire, and then the second operating part 4 is pulled to retrieve the wire clamp.

[0080] At this time, the first operating part 2 can be the hook 21 in the first embodiment, or can be the cooperation form of the first claw 22 and the second claw 23 in the second embodiment.

[0081] In addition, in this embodiment, Figure 5 As shown, the second operating part 4 includes a supporting block 41, a clamping block 42 and a driving member 43.

[0082] The support block 41 is fixedly connected to the second telescopic structure 5;

[0083] There are two clamping blocks 42, and the two clamping blocks 42 are arranged on one side of the support block 41 close to the handle 6;

[0084] The driving member 43 is disposed in the supporting block 41 and is used to drive the two clamping blocks 42 to move toward or away from each other.

[0085] Specifically, the support block 41 provides support for the clamping block 42, and the driving member 43 is started, so that the two clamping blocks 42 move toward each other. At this time, the lower clamping plate on the wire clamp is located between the two clamping blocks 42 and is clamped.

[0086] Furthermore, the driving member 43 includes a pressing block 431, a sliding block 432, an abutting block 433, a second rotating shaft 434 and a spring 435.

[0087] The pressing block 431 is vertically slidably arranged in the supporting block 41, and transverse sliding grooves are provided on both sides of the pressing block 431;

[0088] There are two sliders 432, which are respectively slidably installed in two horizontal sliding grooves. The two sliders 432 are respectively rotatably connected to the two clamping blocks 42. In the initial state, the two clamping blocks 42 are symmetrically arranged in an outward-facing shape of Eight. The two sliders 432 are respectively connected to one end of the two clamping blocks 42, and the sliders 432 slide to drive the corresponding clamping blocks 42 to rotate.

[0089] The spring 435 is disposed between the pressing block 431 and the supporting block 41 . In this embodiment, three springs 435 are provided. It can be known that the number of the springs 435 is not limited, and the springs 435 are used to provide elastic force to the pressing block 431 .

[0090] The abutment block 433 is fixedly connected to the top of the pressing block 431 and extends out of the support block 41; specifically, the abutment block 433 is arranged in the middle position of the top of the pressing block 431. In the driving member 43, the abutment block 433 is used to trigger the movement of the pressing block 431, thereby ultimately driving the two clamping blocks 42 to retract or release to achieve movement toward or away from each other.

[0091] There are two second rotating shafts 434, which are installed on both sides of the support block 41 and are rotatably connected to the two clamping blocks 42. On the one hand, the second rotating shafts 434 drive the corresponding clamping blocks 42 to rotate, and on the other hand, since the second rotating shafts 434 are arranged on one side of the clamping block 42, the second rotating shafts 434, in cooperation with the slider 432, limit the clamping block 42 to a certain position.

[0092] At the beginning, the lower pressing block 431 of the wire clamp first presses against the abutting block 433, where the force pressing the abutting block 433 is the pulling force of the operator; thereby the pressing block 431 moves downward, and the spring 435 is in a compressed state. During the pulling process, since the two clamping blocks 42 are respectively connected to the corresponding second rotating shaft 434, the two sliders 432 move away from each other in the corresponding horizontal slide grooves, and finally drive the two clamping blocks 42 to move toward each other to clamp and lock the lower clamping plate. Since the operator will continuously provide pulling force to the wire clamp, that is, during the movement of the wire clamp, the abutting block 433 is always in a pressing state, so the two clamping blocks 42 remain in a state of facing each other so as to stably clamp and fix the lower clamping plate.

[0093] At the same time, when the operator removes the pulling force, that is, when there is no pulling force pressing on the abutment block 433, the spring 435 rebounds to drive the pressure block 431 to move upward in the support block 41, and the two sliders 432 move toward each other in the corresponding horizontal slide grooves, and finally drive the two clamping blocks 42 to move away from each other to automatically unlock the lower clamping plate, making it easier to remove the auxiliary tool.

[0094] Similar to the first operating part 2, in order to avoid hard contact between the two clamping blocks 42 and the lower clamping plate, the contact surfaces of the two clamping blocks 42 and the lower clamping plate are provided with soft pads, which on the one hand avoid damage to the wire gripper, and on the other hand increase the clamping force between the two clamping blocks 42 and the wire gripper, reducing the risk of the clamping blocks 42 and the wire gripper slipping.

[0095] Since the second operating part can achieve automatic locking (under the action of pulling force), the two clamping blocks 42 can stably cooperate with any suitable position of the lower clamping plate on the wire clamp, avoiding the need for operators to perform multiple alignment operations, reducing the difficulty of the operators' work and alleviating their burden.

[0096] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
