Description

Technical Field

[0001] The present application relates to the technical field of power transmission auxiliary tools, and in particular to a wire clamp auxiliary device suitable for maintenance of electrical components. Background Art

[0002] The wire clamp is a commonly used tool for the maintenance of power transmission equipment. The wire clamp is usually used in conjunction with the wire tensioner. Put the wire clamp on the original line, connect the wire tensioner with the pull ring on the wire clamp and apply tension to it. The wire clamp can clamp the original wire, and the wire tensioner can transfer the tension to the original wire through the wire clamp to prevent the original wire from falling. At this time, the section between the wire clamp and the pole can be disassembled to maintain or replace the electrical components in the section. Therefore, in actual operation, there needs to be a large distance between the wire clamp and the pole to facilitate the replacement / maintenance of electrical components by operators, but too large a distance will bring greater difficulty to the installation and recovery of the wire clamp. The invention patent with publication number CN110323693A discloses a wire holder push-pull rod, which utilizes the extension and retraction of the rod body to realize the pushing and retracting of the wire holder, bringing convenience to the maintenance of the power transmission line. After the wire holder is pushed out, the push-pull rod needs to be buckled on the wire with a safety buckle to keep the push-pull rod in a state, so as to facilitate the staff to operate the push-pull rod. However, when maintaining electrical components, the wire holder is clamped on the wire, and the wire tensioner is used to keep the position of the wire holder, so as to prevent other parts of the wire from falling after the wire at the pole is disassembled. At this time, the safety buckle cannot be buckled on the wire. Even if the safety buckle is buckled on the rope body of the wire tensioner, it will occupy the space between the wire holder and the pole, which is easy to hinder the maintenance of the electrical components. Summary of the invention

DETAILED DESCRIPTION

[0057] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0058] like Figure 1 to Figure 3 As shown, an embodiment of the present application provides a wire gripper auxiliary device suitable for electrical component maintenance, which comprises a wire gripper body 100 , a retracting and releasing mechanism 300 , and a column holding mechanism 200 .

[0059] The wire clamp body 100 is a commonly used wire clamp on the market, which has at least a clamping part and a pull ring for driving the clamping part to open. The pull ring is used to connect the cable body of the wire tensioner. The clamping part is closed by pulling the pull ring, so that the wire clamp body 100 can be clamped on the wire.

[0060] The wire gripper body 100 is connected to the retractable mechanism 300 to drive the wire gripper body 100 to move linearly back and forth. The retractable mechanism 300 can adopt a telescopic rod commonly used on the market, such as the main support rod in a folding umbrella. A pulley rod 3042 is provided on the retractable mechanism 300. The pulley rod 3042 is a structure for rotating and connecting pulleys at both ends of the length of the rod body. The pulley rod 3042 is provided with a driving rope 3045 connected to the pull ring shaft of the wire gripper body 100, so that the clamping part is opened by pulling the driving rope 3045, which means that when the retractable mechanism 300 is controlled to extend, the driving rope 3045 is pulled so that the clamping part of the wire gripper body 100 is always opened, so that the clamping part of the wire gripper body 100 can be aligned with the wire.

[0061] The retractable mechanism 300 is rotatably connected to the column holding mechanism 200, wherein the retractable mechanism 300 can rotate in at least two directions relative to the column holding mechanism 200, for example, the retractable mechanism 300 and the column holding mechanism 200 can be connected by a universal joint, and the column holding mechanism 200 is used to clamp the electric pole 400; after the column holding mechanism 200 is connected to the electric pole 400, the retractable mechanism 300 is rotated in the vertical plane so that the length direction of the retractable mechanism 300 forms an angle with the length direction of the electric pole 400, and after the retractable mechanism 300 is extended so that the wire clamp body 100 is clamped on the electric wire, the electric wire, the electric pole 400 and the retractable mechanism 300 form a triangle, and the space inside the triangle serves as a maintenance space for the staff, and the retractable mechanism 300 is rotated in the horizontal plane so that the wire clamp body 100 can be close to the electric wire and the wire and the clamping part on the wire clamp body 100 can be aligned.

[0062] The embodiment of the present application provides a wire holder auxiliary device suitable for maintenance of electrical devices. Through the retracting and releasing movement of the retracting and releasing mechanism 300, the wire holder body 100 can be driven to approach / move away from the electric pole 400, thereby facilitating the installation or recovery of the wire holder body 100. The retracting and releasing mechanism 300 is connected to the electric pole 400 through the pole holding mechanism 200. The state of the retracting and releasing mechanism 300 is relatively stable, which can bring convenience to the installation / recovery of the wire holder body 100. That is, if there is no pole holding mechanism 200, the staff will need to hold the retracting and releasing mechanism 300 to align the wire holder body 100 on the retracting and releasing mechanism 300 with the farther electric wire. In this process, the staff usually needs to stretch their arms, which will be inconvenient for the alignment of the wire holder body 100 with the electric wire. After being connected to the electric pole 400 through the pole holding mechanism 200, the state of the retracting and releasing mechanism 300 is relatively stable. , it is easier to stably control the position of the wire gripper body 100. At the same time, when the retracting mechanism 300 rotates relative to the pole holding mechanism 200, on the one hand, a larger space can be freed up under the wire tensioner, that is, the installation height of the pole holding mechanism 200 on the pole 400 can be lowered, and the retracting mechanism 300 is rotated so that its retracting direction forms an angle with the pole 400, and then the retracting mechanism 300 is extended to make the wire gripper body 100 cooperate with the wires farther away. On the other hand, it is convenient to align the wire tensioner with the wires, that is, the retracting mechanism 300 can be rotated in the horizontal plane so that the wire gripper body 100 can be clamped on or removed from the wires in the horizontal direction. Such an installation / removal method can also avoid the wear of the wires by the clamping part on the wire gripper body 100, and at the same time avoid large disturbances to the wires due to the large friction between the clamping part and the wires.

[0063] Since the length direction of the retractable mechanism 300 is not fixed during use, the installation method of the wire clamp body 100 on the retractable mechanism 300 should have a certain tolerance. For example, in some optional embodiments, Fig. 9As shown, the retractable mechanism 300 is connected with a mounting base plate 3041, which is a rectangular plate, and the first positioning blocks 3043 are respectively connected to the width sides of the mounting base plate 3041, and the end of the mounting base plate 3041 away from the retractable mechanism 300 in the length direction is connected to the second positioning block 3044. The two first positioning blocks 3043 and the second positioning block 3044 jointly enclose a positioning space, wherein the first positioning block 3043 is provided with a fixing bolt, and after the wire clamp body 100 is placed in the positioning space, the posture of the wire clamp body 100 is adjusted so that the clamping gap of the clamping part is in the expected posture, and then the wire clamp body 100 and the mounting base plate 3041 are relatively fixed by the fixing bolt. Among them, the pulley rod 3042 is fixedly connected to the mounting base plate 3041 by bolts.

[0064] In some optional embodiments, see Figure 4 and Figure 5 The column holding mechanism 200 may specifically include a first holding arm 201, a second holding arm 202 and a clamping driving mechanism.

[0065] The first holding arm 201 may be configured as a hollow rectangular parallelepiped member.

[0066] There are two second arms 202, which may also be rectangular components. The second arms 202 are provided with anti-slip pads 500 for contacting the poles 400. The two second arms 202 are respectively rotatably connected to the two ends of the length of the first arm 201. Specifically, the two second arms 202 may be respectively rotatably connected to the two ends of the length of the first arm 201 via hinges.

[0067] The clamping drive mechanism is arranged in the first arm 201, and the two second arms 202 are respectively connected to the clamping drive mechanism so as to rotate relative to the first arm 201 under the drive of the clamping drive mechanism. After the staff climbs up the pole 400, the two second arms 202 can be rotated relative to the first arm 201 to clamp the pole 400 only by operating the clamping drive mechanism. The operation is convenient and the workload of high-altitude operations is reduced. When not in use, the second arms 202 can be driven by the clamping drive mechanism to rotate so that the length directions of the first arm 201 and the second arm 202 coincide, and then the retracting mechanism 300 is rotated so that the length direction of the retracting mechanism 300 is parallel to the length direction of the first arm 201, thereby reducing the space occupied by the entire device and facilitating storage.

[0068] In some optional embodiments, see Figure 4 , Figure 5 and Figure 7 The clamping driving mechanism may specifically include a clamping handle 203 , a double-ended lead screw 204 , a clamping slider 206 , a first slide bar 210 and a second slide bar 212 .

[0069] One end of the clamping handle 203 is located inside the first arm 201 , and the other end is located outside the first arm 201 for a person to hold.

[0070] The double-headed screw 204 is rotatably arranged in the first arm 201, and the axial direction of the double-headed screw 204 is parallel to the length direction of the first arm 201. The double-headed screw 204 is connected to the clamping handle 203 through the first transmission assembly 205 so that the clamping handle 203 can drive the double-headed screw 204 to rotate. That is, when the staff operates the clamping handle 203, the double-headed screw 204 can be driven to rotate in the first arm 201 through the first transmission assembly 205. The first transmission assembly 205 can be configured as a bevel gear transmission mechanism.

[0071] The two clamping sliders 206 are respectively threadedly connected to the double-ended screw 204, which means that when the double-ended screw 204 is rotated, the two clamping sliders 206 move away from or approach each other. The clamping slider 206 has a surface that contacts the inner wall of the first arm 201 to prevent the clamping slider 206 from rotating with the double-ended screw 204.

[0072] The two first slide bars 210 are respectively connected to the two clamping sliders 206 and are slidably connected to the first arm 201. Specifically, a slide bar seat 211 can be connected to the inner wall of the first arm 201, and the first slide bar 210 can movably pass through the slide bar seat 211 to achieve a sliding connection. A linear bearing can be arranged between the first slide bar 210 and the slide bar seat 211 to improve the sliding smoothness. The axis of the first slide bar 210 is parallel to the axis of the double-headed screw 204. The end of the first slide bar 210 away from the clamping slider 206 can pass through the first arm 201 and be located outside the first arm 201, which means that the end of the first arm 201 in the length direction is provided with an avoidance hole for the first slide bar 210 to pass through. When the double-headed screw 204 rotates, the two clamping sliders 206 drive the two first slide bars 210 to move toward the two ends of the first arm 201 in the length direction so that the ends of the first slide bars 210 pass through the avoidance hole.

[0073] The two second slide bars 212 are respectively connected to the two clamping sliders 206 and are slidably connected to the first arm 201. The second slide bars 212 may be arranged in the same manner as the first slide bars 210, which will not be described in detail herein.

[0074] One end of the first slide bar 210 and the second slide bar 212 are located outside the first arm 201 and are both provided with a sliding notch, the length direction of the sliding notch coincides with the length direction of the first slide bar 210 / the second slide bar 212, and the end of the second arm 202 is provided with a swing rod 2021 located in the sliding notch, and the swing rod 2021 is rotatably connected to the first slide bar 210 / the second slide bar 212, for example, a rotating shaft 2101 is provided in the sliding notch, and a swing rod 2021 is provided with a swing rod 2021 in the length direction of the swing rod 2021. The overlapping sliding grooves are sleeved on the rotating shaft 2101, so that the ends of the first sliding bar 210 / the second sliding bar 212 can slide along the length direction of the sliding groove and the swing rod 2021 and the first sliding bar 210 / the second sliding bar 212 can rotate relative to each other; when the first sliding bar 210 / the second sliding bar 212 slides back and forth on the first holding arm 201, the rotating shaft 2101 can pull or push the swing rod 2021 to drive the second holding arm 202 to rotate, so that the column holding mechanism 200 can clamp the pole 400.

[0075] See also Figures 4 to 6 In some optional embodiments, a driving slide hole is provided on the clamping slider 206, and the length direction of the driving slide hole forms an angle with the length direction of the double-headed lead screw 204; an L-shaped clamping slide 207 is provided on the first arm 201, and a locking component 208 is slidably matched in the clamping slide 207; wherein, the first slide bar 210 and the second slide bar 212 are connected to the clamping slider 206 through the clamping transmission rod 209, and the clamping transmission rod 209 is movably inserted into the clamping slider 206 so that one end of the clamping transmission rod 209 can slide in the clamping slider 206, and one end of the second slide bar 212 is constructed with a locking groove suitable for inserting the locking component 208.

[0076] according to Figure 4 and Figure 5In the initial state, the locking assembly 208 is located at the highest position of the driving sliding hole and at the rightmost end of the clamping slideway 207. When the clamping slider 206 slides to the left, since the clamping transmission rod 209 is movably arranged in the clamping slider 206, the clamping slider 206 can first slide on the clamping transmission rod 209 for a certain distance, and then the clamping slider 206 drives the clamping transmission rod 209 to move to the left together. When the locking assembly 208 moves to the leftmost end of the clamping slideway 207, since the driving sliding hole and the length direction of the double-headed lead screw 204 form an angle, the clamping slider 206 continues to move to the left. When sliding to the left, the locking component 208 can move downward. At the same time, the driving slider continues to drive the second sliding bar 212 to move to the left. When the locking component 208 slides to the bottom of the clamping slide 207, the locking component 208 is inserted into the locking groove of the second sliding bar 212 to limit the second sliding bar 212 in the left and right directions. This can prevent the second arm 202 from rotating relative to the first arm 201, so that the straight shape of the first arm 201 and the second arm 202 is maintained, that is, preventing the first arm 201 and the second arm 202 from rotating relative to each other during storage.

[0077] In some optional embodiments, please refer to Figure 6 The locking assembly 208 may specifically include a locking slide bar 2081 , a locking sleeve 2082 and a locking pin 2083 .

[0078] The locking slide bar 2081 is slidably matched with the clamping slide channel 207 , which means that the locking slide bar 2081 can slide freely in the clamping slide channel 207 .

[0079] The locking sleeve 2082 is connected to the locking slide bar 2081 , and the locking sleeve 2082 may be a round sleeve.

[0080] The locking pin 2083 is movably inserted into the locking sleeve 2082 , which means that the locking pin 2083 can slide freely along the axial direction of the locking sleeve 2082 , and an elastic member 2084 is arranged between the locking pin 2083 and the locking sleeve 2082 .

[0081] Among them, one end of the locking pin 2083 away from the locking sleeve 2082 is configured with a wedge surface for contacting the second sliding rod 212 .

[0082] In this way, when the end of the second slide bar 212 contacts the wedge surface, the second slide bar 212 can support the locking pin 2083, that is, the locking pin 2083 slides in the locking sleeve 2082. When the locking pin 2083 corresponds to the position of the locking groove, the locking pin 2083 slides in the opposite direction under the elastic force of the elastic member 2084 to enter the locking groove to limit the second slide bar 212.

[0083] In order to improve the relative sliding smoothness between the second sliding rod 212 and the locking pin 2083 , a corresponding wedge surface may also be provided on the second sliding rod 212 .

[0084] In some optional embodiments, the elastic member 2084 is configured as a compression spring.

[0085] In some optional embodiments, see Figure 8 The retracting and releasing mechanism 300 may specifically include a first sleeve 301 , a second sleeve 302 , a third sleeve 303 , a driving screw 305 and a retracting and releasing handle 309 .

[0086] The first sleeve 301 is a square sleeve, and the first sleeve 301 is rotatably connected to the column holding mechanism 200 .

[0087] The second sleeve 302 is a square tube, and the second sleeve 302 is movably inserted into the first sleeve 301. A long hole is opened on the side wall of the second sleeve 302, and a first pulley group 306 is arranged in the long hole, wherein two pulleys of the first pulley group 306 are arranged at both ends of the long hole in the length direction, and the rope body between the two pulleys is connected to the first sleeve 301. Specifically, the rope body of the first pulley group 306 close to the first sleeve 301 is connected to the first sleeve 301.

The third sleeve 303 is connected to the cable body in the first pulley block 306 . Specifically, the cable body in the first pulley block 306 away from the first sleeve 301 is connected to the third sleeve 303 .

[0089] The driving screw 305 is coaxially threaded with the second sleeve 302 and is coaxially rotatably connected with the first sleeve 301, so that rotating the driving screw 305 can make the second sleeve 302 slide in the first sleeve 301. When the first sleeve 301 and the second sleeve 302 produce relative movement, the pulley in the first pulley group 306 can be driven by the cable body to rotate, and the cable body can also mobilize the third sleeve 303 to slide in the second sleeve 302.

[0090] The retractable handle 309 is connected to the drive screw 305 through the second transmission assembly 308 to drive the drive screw 305 to rotate, so that the drive screw 305 can be driven to rotate by operating the retractable handle 309, thereby causing the second sleeve 302 and the third sleeve 303 to slide at the same time to achieve the extension or shortening of the retractable mechanism 300.

In this way, the extension distance of the retracting and releasing mechanism 300 can be increased, and the cable take-up device can be installed at a farther position.

[0092] In the embodiment of the present application, the retracting and extending mechanism 300 is relatively fixed by the column holding mechanism 200. The length of the retracting and extending mechanism 300 can be conveniently adjusted by the retracting and extending handle 309 only when the retracting and extending mechanism 300 is in a relatively fixed state.

And when the first sliding sleeve slides on the straight line segment, the retracting mechanism 300 can be translated in the horizontal direction as a whole, so as to facilitate the alignment operation of the clamping part on the wire clamp body 100 and the wire.

[0095] In some optional embodiments, the limiting assembly is configured as a ratchet mechanism. Specifically, a ratchet can be provided on the outer wall of the first sleeve, and a pawl can be provided on the second sleeve, so that after adjusting the angle of the retracting mechanism 300, the ratchet mechanism can automatically form a rotation limit for the second sleeve. Of course, the pawl is an operable pawl, for example, pulling the pawl can make the end of the pawl disengage from the ratchet, which is a common structure in the prior art, so that the one-way limit of the second sleeve can be contacted.
