Description

Technical Field

[0001] This invention relates to the field of parallel trench clamp installation equipment technology, specifically to an electric installation device for parallel trench clamps and a method for connecting conductors during live-line work. Background Technology

[0002] Power engineering materials are mainly used in power line engineering to connect conductors. Among them, parallel groove clamps are used to connect small and medium cross-section aluminum stranded wire or steel-cored aluminum stranded wire and steel stranded wire of overhead lightning protection wire in positions where they are not subjected to tension. They are also used for jumper connections of non-straight towers.

[0003] Currently, common parallel groove clamps (such as...) Figure 1 The clamp (as shown) includes an upper clamp plate, a lower clamp plate, and two locking bolts. The upper and lower clamp plates are fixed by the locking bolts. Two clamping grooves are provided on opposite sides of the upper and lower clamp plates. When the upper and lower clamp plates are close together, the corresponding clamping grooves form conductor positioning holes. The parallel groove clamp is installed onto the two conductors to be paralleled through the two conductor positioning holes. However, since parallel groove clamps are usually used during live-line work, the entire process of installing two conductors requires manual operation, making the conductor paralleling operation cumbersome. This is especially inconvenient when working at heights, requiring multiple people to operate simultaneously, and easily creating safety hazards.

[0004] In the prior art, Chinese utility model patent with publication number CN216355689U discloses "a parallel groove clamp installation tool", which realizes automatic clamping or loosening of the parallel groove clamp through a parallel groove clamp clamping component, a lifting component and a screw tightening component, and simultaneously tightens multiple bolts of the parallel groove clamp while ensuring the lead wire is pressed. However, the above-mentioned patent technology has a complex structure, cannot be mass-produced in reality through industrial processing, and cannot meet the needs of live work or high-altitude work. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an electric installation device for parallel trench clamps and a method for connecting conductors under live-line working conditions. The device includes a clamping mechanism, a branch conductor pre-clamping mechanism, and a clamp locking mechanism. This enables the clamping of the parallel trench clamps, the pre-clamping of the branch conductors, and the locking of the parallel trench clamps in live environments and under high-altitude working conditions. This reduces the labor intensity of operators and provides strong support for the stable operation of the power system.

[0006] The technical solution of the present invention is as follows:

[0007] An electric installation device for a parallel trench clamp during live-line working includes a clamp body and an insulating rod. A clamping mechanism is detachably connected to the top of the insulating rod. An assembly groove for placing the clamp body is opened on one side of the clamping mechanism. A branch conductor pre-clamping mechanism is connected to the other side of the clamping mechanism. A clamp locking mechanism is connected to the bottom of the assembly groove.

[0008] Furthermore, the clamp body includes an upper clamp plate and a lower clamp plate that cooperate with each other. The upper clamp plate and the lower clamp plate are locked together by fastening bolts. Two arc-shaped wire grooves are respectively opened on the opposite sides of the upper clamp plate and the lower clamp plate.

[0009] Furthermore, the top wall of the assembly groove is provided with a slot that engages with the upper clamping plate, and a through hole is provided above the slot for the fastening bolt to pass through.

[0010] Furthermore, the clamp locking mechanism includes two locking rods that pass through the bottom wall of the assembly groove side by side. One end of the locking rod located in the assembly groove is provided with a bolt sleeve adapted to the fastening bolt. A compression spring is provided between the bottom wall of the assembly groove and the bottom of the bolt sleeve, and the compression spring is sleeved on the outside of the locking rod.

[0011] Furthermore, a gear chamber is provided at the bottom of the assembly slot, and a gear transmission assembly for meshing transmission is rotatably connected in the gear chamber. The gear transmission assembly includes a driving gear, a transition gear, and a toothed ring sleeved on the outside of the locking rod. The transition gear meshes with the driving gear and the two toothed rings respectively.

[0012] Furthermore, each of the locking rods is threadedly connected to a positioning rod at its bottom, and the bottom of each of the two positioning rods is rotatably connected to the same steel plate.

[0013] Furthermore, the branch wire pre-clamping mechanism includes two clamping plates that cooperate with the top of the assembly slot to clamp the branch wire. The two clamping plates are respectively hinged to both sides of the clamping mechanism. The clamping mechanism is provided with a servo motor chamber. A remote control servo motor is fixedly installed in the servo motor chamber. Connecting blocks are hinged to both sides of the servo motor handle. A push rod is fixedly connected to the other end of the connecting block. A slider is slidably connected to the other end of the push rod. The slider is hinged to the corresponding clamping plate. A push spring is provided between the connecting block and the slider. The push spring is sleeved on the outside of the push rod.

[0014] Furthermore, a limiting connecting sleeve is fitted on the outer wall of the insulating rod, and a limiting sleeve is slidably connected inside the limiting connecting sleeve. A pull rope is fixedly threaded through the limiting sleeve, the upper end of the pull rope is hinged to the steel sheet, and the other end of the pull rope is hinged to a handheld sleeve, which is fitted on the outer wall of the insulating rod. A spring pin is installed on the limiting connecting sleeve, and a groove is formed on the outer wall of the limiting sleeve to cooperate with the spring pin.

[0015] Furthermore, a battery module is inserted into the clamping mechanism, a drive component is connected to the input end of the gear transmission assembly, and the battery module is electrically connected to the drive component and the remote control servo motor.

[0016] A method for connecting the conductors of an electrically operated installation device for a parallel trench clamp during live-line working mainly includes the following steps:

[0017] S1. Tighten the upper clamping plate and the lower clamping plate with fastening bolts. At this time, the upper clamping plate and the lower clamping plate are close to each other, and the wire clamp body is placed in the assembly groove.

[0018] S2. Move the spring pin to remove the restriction of the spring pin on the limiting sleeve. Under the action of the spring return force, the locking rod pushes the wire clamp body into the slot, activates the drive component of the gear transmission assembly, and makes the locking rod rotate. At the same time, the bolt sleeve drives the fastening bolt to rotate. At this time, the upper clamp plate and the lower clamp plate move away from each other, the locking rod moves downward, and the compression spring is compressed.

[0019] S3. Pass the branch wire through the clamping plate and place it in the corresponding arc-shaped groove on the inner side. Start the remote control servo motor so that the clamping plate can initially position the branch wire with the cooperation of the assembly groove.

[0020] S4. Hold the insulating rod close to the main wire and place the main wire in the corresponding arc-shaped groove on the outside. Start the drive component of the gear transmission assembly in the reverse direction to make the locking rod rotate in the reverse direction. The bolt sleeve drives the fastening bolt to rotate in the reverse direction. At this time, the upper clamp and the lower clamp are close to each other. At the same time, the compression spring pushes the locking rod to move upward during the rotation until the clamp body completes the clamping of the branch wire and the main wire.

[0021] S5. Move the spring pin, which restricts the limiting sleeve, causing the pull rope to move the locking rod downward, separating the bolt sleeve from the fastening bolt, and reversing the remote control servo motor to separate the clamping plate from the branch wire, thereby completely disengaging the electric installation device from the main line, branch wire, and clamp body 1.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention can meet the requirements of single-person installation of traditional parallel trench clamps, and can also be installed in live environments and at height. It is equipped with a clamping mechanism, a branch conductor pre-clamping mechanism, and a clamp locking mechanism. Through electric drive and mechanical design, it can achieve fast and accurate connection of conductors, improve the efficiency and safety of conductor connection in live work, reduce the labor intensity of operators, and provide a strong guarantee for the stable operation of the power system.

[0032] To make the content of this invention easier to understand, the technical solutions of this invention will be further described below in conjunction with specific embodiments and accompanying drawings, but this invention is not limited thereto.

[0033] Example 1

[0034] Please see Figure 2 A live-line working electric installation device for a parallel trench clamp includes a clamp body 1 and an insulating rod 2. A clamping mechanism 3 is detachably connected to the top of the insulating rod 2. An assembly groove 301 for placing the clamp body 1 is opened on one side of the clamping mechanism 3. A branch conductor pre-clamping mechanism 4 is connected to the other side of the clamping mechanism 3. A clamp locking mechanism 5 is connected to the bottom of the assembly groove 301.

[0035] Combination Figure 1 The clamp body 1 includes an upper clamp plate 101 and a lower clamp plate 102 that cooperate with each other. The upper clamp plate 101 and the lower clamp plate 102 are locked together by fastening bolts 103. Two arc-shaped wire grooves 104 are respectively opened on the opposite sides of the upper clamp plate 101 and the lower clamp plate 102.

[0036] As can be seen from the above description, in a live environment and under high-altitude working conditions, the operator can put the clamp body 1 into the assembly slot 301, and then pre-clamp the branch conductor through the branch conductor pre-clamping mechanism 4. Then, the operator can move the electric installation device to the position of the main conductor by holding the insulating rod 2, and insert the main conductor into the arc-shaped wire groove 104. Finally, the clamp locking mechanism 5 is used to lock the main conductor and the branch conductor.

[0037] Example 2

[0038] Please see Figure 3 The top wall of the assembly slot 301 is provided with a slot 302 that engages with the upper clamping plate 101, and a through hole 303 is provided above the slot 302 for the fastening bolt 103 to pass through. When the fastening bolt 103 is tightened, the upper clamping plate 101 is engaged in the slot 302, the lower clamping plate 102 gradually moves upward, and the upper end of the fastening bolt 103 passes through the through hole 303.

[0039] Combination Figure 4 The wire clamp locking mechanism 5 includes two locking rods 501 that pass through the bottom wall of the assembly groove 301 side by side. One end of the locking rod 501 located in the assembly groove 301 is provided with a bolt sleeve 502 that is adapted to the fastening bolt 103. A compression spring 503 is provided between the bottom wall of the assembly groove 301 and the bottom of the bolt sleeve 502. The compression spring 503 is sleeved on the outside of the locking rod 501, and the upper end of the compression spring 503 is in a free state, abutting against the bottom of the bolt sleeve 502.

[0040] As can be seen from the above description, after the fastening bolt 103 is inserted into the bolt sleeve 502, when it is necessary to lock the wire clamp body 1, the locking rod 501 is rotated, and the fastening bolt 103 and the lower clamp plate 102 gradually move upward. At the same time, the locking rod 501 moves upward under the action of the rebound force of the compression spring 503. When it is necessary to loosen the wire clamp body 1, the locking rod 501 is rotated in the opposite direction, and the fastening bolt 103 and the lower clamp plate 102 gradually move downward. At the same time, the locking rod 501 moves downward, and the compression spring 503 is in a compressed state.

[0041] Example 3

[0042] The bottom of the assembly slot 301 is provided with a gear chamber 504. A gear transmission assembly for meshing transmission is rotatably connected in the gear chamber 504. The gear transmission assembly includes a driving gear, a transition gear, and a toothed ring 505 sleeved on the outside of the locking rod 501. The transition gear meshes with the driving gear and the two toothed rings 505 respectively. The input end of the gear transmission assembly is connected to a drive assembly.

[0043] As a further preferred embodiment, the locking rod 501 is a hexagonal prism, and the inner wall of the toothed ring 505 is a hexagonal structure that cooperates with the locking rod 501, thereby driving the locking rod 501 to rotate.

[0044] As a further preferred embodiment, since the center distance between the two locking rods 501 is limited by the center distance between the two fastening bolts 103, in order to meet the torque requirements required in the gear design process, the gear ring 505 needs to meet a certain number of teeth. Therefore, by arranging the gear rings 505 of the two locking rods 501 in an alternating manner, the effective number of teeth can be increased under the given spatial constraints, thereby enhancing the torque transmission capability of the gear.

[0045] As a further preferred embodiment, the drive assembly includes a motor and a reducer. Alternatively, an existing impact drill assembly can be used. The motor and reducer are fixedly installed in the gear chamber 504, and the output end of the reducer is connected to the drive gear.

[0046] As can be seen from the above description, the motor drives the drive gear to rotate through the reducer, which in turn drives the meshing transition gear to rotate, which in turn drives the meshing gear ring 505 to rotate, thereby realizing the rotation of the locking rod 501.

[0047] Example 4

[0048] Please see Figure 5The branch wire pre-clamping mechanism 4 includes two clamping plates 401 that cooperate with the top of the assembly slot 301 to clamp the branch wire. The clamping plates 401 on both sides are respectively hinged to the two sides of the clamping mechanism 3. The clamping mechanism 3 is provided with a servo chamber. A remote control servo 402 is fixedly installed in the servo chamber. Connecting blocks 403 are hinged to both sides of the servo handle of the remote control servo 402. A push rod 404 is fixedly connected to the other end of the connecting block 403. A slider 405 is slidably connected to the other end of the push rod 404, and the other end of the push rod 404 passes through the slider 405. The slider 405 is hinged to the corresponding clamping plate 401. A push spring 406 is provided between the connecting block 403 and the slider 405. The push spring 406 is sleeved on the outside of the push rod 404.

[0049] As a further preferred embodiment, the top of the clamping plate 401 is provided with a wire-locking groove that fits with the branch wire.

[0050] As a further preferred embodiment, the upper end of the push spring 406 abuts against the bottom of the slider 405, and the lower end of the push spring 406 abuts against the top of the connecting block 403.

[0051] As can be seen from the above description, after the branch wire is placed into the inner arc-shaped wire groove 104, the branch wire needs to be pre-clamped. The remote control servo motor 402 is started. The servo handle of the remote control servo motor 402 drives the connecting blocks 403 on both sides to rotate around the hinge point. The push rod 404 is pushed upward, thereby driving the slider 405 to move upward. The wire clamping groove of the clamping plate 401 cooperates with the upper clamping plate 101 to perform preliminary positioning of the branch wire.

[0052] Specifically, during the rotation of the clamping plate 401, the clamping plate 401 is not directly pushed by the push rod 404 and the remote control servo motor 402. Instead, the slider 405 is pushed by the push spring 406. The clamping plate 401 can automatically adapt to the swing amplitude of the clamping plate 401 according to the specifications of the branch wire, so as to avoid damage to the branch wire during the clamping process.

[0053] Example 5

[0054] The bottom of each locking rod 501 is threaded with a positioning rod 506. During the rotation of the locking rod 501, the positioning rod 506 rotates synchronously. The bottom of each positioning rod 506 is rotatably connected to the same steel plate 507.

[0055] As a further preferred embodiment, a limiting connecting sleeve 201 is fitted on the outer wall of the insulating rod 2. A limiting sleeve 202 is slidably connected inside the limiting connecting sleeve 201. A pull rope 203 is fixedly threaded through the limiting sleeve 202. The pull rope 203 is made of rigid steel strand. The upper end of the pull rope 203 is hinged to the steel sheet 507. The other end of the pull rope 203 is hinged to a handheld sleeve 204. The handheld sleeve 204 is fitted on the outer wall of the insulating rod 2. A spring pin 205 is installed on the limiting connecting sleeve 201. A groove is opened on the outer wall of the limiting sleeve 202 to cooperate with the spring pin 205. The end of the spring pin 205 can extend into the limiting connecting sleeve 201 and cooperate with the groove of the limiting sleeve 202. By moving the spring pin 205, the state of the pull rope 203 can be restricted or released.

[0056] As a further preferred embodiment, the spring pin 205 is a commercially available knob-type plunger spring pin.

[0057] Example 6

[0058] A battery module 6 is inserted into the clamping mechanism 3. The battery module 6 is electrically connected to the drive component and the remote control servo motor 402, and the battery module 6 provides power to the drive component and the remote control servo motor 402.

[0059] Example 7

[0060] A method for connecting the conductors of an electrically operated installation device for a parallel trench clamp during live-line working mainly includes the following steps:

[0061] S1. Tighten the upper clamping plate 101 and the lower clamping plate 102 with the fastening bolts 103. At this time, the upper clamping plate 101 and the lower clamping plate 102 are close to each other, and the wire clamp body 1 is placed in the assembly groove 301.

[0062] S2. Move the spring pin 205 to remove the restriction of the spring pin 205 on the limiting sleeve 202. Under the action of the spring force of the compression spring 503, the locking rod 501 pushes the wire clamp body 1 into the slot 302, starts the drive component of the gear transmission assembly, and makes the locking rod 501 rotate. At the same time, the bolt sleeve 502 drives the fastening bolt 103 to rotate. At this time, the upper clamp plate 101 and the lower clamp plate 102 move away from each other, the locking rod 501 moves downward, and the compression spring 503 is compressed.

[0063] After steps S1 and S2, it can be ensured that the two fastening bolts 103 of the clamp body 1 have the same stroke, avoiding the situation where the two fastening bolts 103 have different strokes, and preventing the clamp body 1 from clamping the main wire and the branch wire with inconsistent force.

[0064] S3. Pass the branch wire through the clamping plate 401 and place it in the corresponding arc-shaped wire groove 104 on the inner side. Start the remote control servo motor 402 so that the clamping plate 401 can perform preliminary positioning of the branch wire with the cooperation of the assembly groove 301.

[0065] S4. Hold the insulating rod 2 close to the main wire, so that the main wire is placed in the corresponding arc-shaped wire groove 104 on the outside. Start the drive component of the gear transmission assembly in reverse, so that the locking rod 501 rotates in reverse. The bolt sleeve 502 drives the fastening bolt 103 to rotate in reverse. At this time, the upper clamping plate 101 and the lower clamping plate 102 approach each other. At the same time, the compression spring 503 pushes the locking rod 501 to move upward during the rotation until the clamp body 1 completes the clamping of the branch wire and the main wire.

[0066] S5. Move the spring pin 205. The spring pin 205 restricts the limit sleeve 202, causing the pull rope 203 to drive the locking rod 501 to move downward. The bolt sleeve 502 separates from the fastening bolt 103, and the remote control servo motor 402 is activated in the reverse direction, so that the clamping plate 401 is separated from the branch line, thereby completely disengaging the electric installation device from the main line, branch line, and clamp body 1.

[0067] As can be seen from the above description, the electric installation device for parallel groove clamps can meet the requirements of a single person installing traditional parallel groove clamps, and can also be used to install parallel groove clamps in live environments and at height.

[0068] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
