Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power construction, and particularly relates to a high-altitude stringing protection device for power construction. BACKGROUND

[0002] In the high-altitude stringing operation of power construction, the overhead wire needs to be stably fixed on the power iron tower to prevent the wire from deviating or sliding during stringing or subsequent construction. However, the traditional protection device relies on a single clamping structure for limiting, which is difficult to adapt to the adjustment requirements of different specifications of the wire, and the limiting stability of the top and both sides of the wire is insufficient. The wire is prone to displacement due to loose parts, and it is difficult to meet the requirements of the stability of the device for high-altitude operation, which brings inconvenience to power construction.

[0003] In addition, the current part of the high-altitude stringing protection device for power construction lacks an efficient transmission mechanism, and the adjustment of the wire clamping part and the limiting part needs to be manually operated in steps, which is time-consuming and laborious, and it is difficult to guarantee the efficiency of high-altitude operation. The limiting of both sides of the wire is mostly a single abutting structure without anti-skid and double limiting design, which is prone to lateral displacement of the wire due to construction vibration. The positioning assembly of part of the device has poor fixing effect and is prone to looseness after long-term use, which increases the safety hazards and maintenance costs of power construction.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1: This example provides a high-altitude overhead power line protection device for power construction. See [link / reference] Figures 1 to 7 The system includes a base plate 100, on which a semi-circular clamping plate 106 and a pair of fixed side plates 200 are mounted. Several pairs of fixed lugs 103 are fixedly mounted on the base plate 100. A pair of bolts 107 are inserted into the semi-circular clamping plate 106, and the bolts 107 are threadedly locked to the base plate 100. A rectangular slide block 201 is fixedly mounted on the top of the fixed side plates 200. A rectangular slide rod 202 is slidably inserted into the rectangular slide block 201, and a rectangular connecting plate 203 is fixed between the pair of rectangular slide rods 202. A wire-clamping roller 205 is rotatably mounted between the rectangular connecting plate 203 and the base plate 100 via a rotating assembly. The wire-clamping roller 205 and the semi-circular clamping plate 106 are connected to the base plate 100. An overhead wire 208 is placed between the circular plates 106; a horizontal shaft 300 is rotatably inserted between a pair of fixed side plates 200, and a pair of arc-shaped plates 302 are fixed at both ends of the horizontal shaft 300. The arc-shaped plates 302 are connected to the rectangular slide rod 202 on the same side through a hinge assembly, and the outer arc surfaces of the pair of arc-shaped plates 302 respectively abut against the outer walls of the overhead wire 208 on both sides; a fixed connecting plate 400 is fixed on the rectangular connecting plate 203, and a sleeve 401 is fixed on the fixed connecting plate 401. An inner cylinder 404 is slidably inserted inside the sleeve 401, and the inner cylinder 404 is engaged with the base plate 100 through a positioning assembly.

[0031] Specifically, several pairs of integrally formed fixing lugs 103 are fixedly provided on both sides of the base plate 100. Each fixing lug 103 has a mounting hole for installation and fixing. The base plate 100 is installed on the power tower through the fixing lugs 103 to provide stable support. A semi-circular clamping plate 106 is detachably installed on the top front of the base plate 100. The semi-circular clamping plate 106 and the wire clamping roller 205 form a clamping space to limit the top of the overhead wire 208. A pair of fixed side plates 200 are symmetrically fixed on the bottom front of the base plate 100. Each fixed side plate 200 has an integrally formed rectangular slide block 201 fixed on the top outer side. Rectangular slide rods 202 are slidably inserted vertically inside the 1. The rectangular slide rods 202 can drive the rectangular connecting plate 203 to move up and down, thereby adjusting the position of the wire clamping roller 205. A rectangular connecting plate 203 is fixed between the top ends of a pair of rectangular slide rods 202. The rectangular connecting plate 203 transmits the sliding power of the rectangular slide rods 202 to the central shaft 204 and the wire clamping roller 205, causing the wire clamping roller 205 to move synchronously. The wire clamping roller 205 can rotate with the central shaft 204 to reduce friction when the overhead wire 208 moves. The engagement space formed between the wire clamping roller 205 and the semi-circular clamping plate 106 is used to engage and place the U-shaped overhead wire 208.

[0032] A horizontal shaft 300 is rotatably inserted between the bottoms of a pair of fixed side plates 200. The horizontal shaft 300 can drive the arc-shaped plate 302 to rotate synchronously, providing rotational support and power transmission for the arc-shaped plate 302. A pair of arc-shaped plates 302 are symmetrically fixed at both ends of the horizontal shaft 300. Each arc-shaped plate 302 is connected to the bottom end of a rectangular slide rod 202 on the same side through a hinge assembly. The outer arc surfaces of the pair of arc-shaped plates 302 respectively abut against both sides of the overhead power line 208. On the outer wall; a fixed connecting plate 400 is vertically fixed in the middle of the rectangular connecting plate 203 to transmit the positioning force of the inner cylinder 404 to the rectangular connecting plate 203 and restrict its sliding; an integrally formed sleeve 401 is fixed at the bottom end of the fixed connecting plate 400. The sleeve 401 provides sliding space and support for the inner cylinder 404. The inner cylinder 404 can restrict the movement of the sleeve 401, the fixed connecting plate 400 and the rectangular connecting plate 203, thereby fixing the position of the wire clamping roller 205 and the arc plate 302.

[0033] A pair of rectangular notches are symmetrically provided at the two corners of the top of the semicircular card plate 106. A bolt 107 is movably inserted into the interior of each rectangular notch. The inner end of each bolt 107 passes through the semicircular card plate 106 and is threadedly locked with a threaded hole at the corresponding position of the base plate 100, so as to realize the detachable fixing of the semicircular card plate 106 and the base plate 100.

[0034] The rotating assembly includes a central shaft 204. A rectangular sliding hole 101 is provided on the base plate 100 at the position corresponding to the wire-clamping roller 205. A rectangular slider 207 is slidably fitted inside the rectangular sliding hole 101 along the vertical direction. The central shaft 204 is inserted through the middle of the rectangular connecting plate 203 and the middle of the rectangular slider 207. The two ends of the central shaft 204 are rotatably connected to the rectangular connecting plate 203 and the rectangular slider 207, respectively. The wire-clamping roller 205 is fixedly sleeved in the middle of the central shaft 204 and can rotate synchronously with the central shaft 204. The rectangular sliding hole 101 can restrict the movement trajectory of the rectangular slider 207, ensuring that the wire-clamping roller 205 smoothly approaches or moves away from the semi-circular clamping plate 106 in the vertical direction.

[0035] The inner ring surface of the semicircular card plate 106 is provided with a semicircular slot 108 that fits the top of the overhead wire 208. Preferably, the inner wall of the semicircular slot 108 is provided with a plurality of first anti-slip grooves evenly distributed along the circumference. The outer ring surface of the wire clamping roller 205 is provided with an annular slot 206 that fits the top of the overhead wire 208. Preferably, the inner wall of the annular slot 206 is provided with a plurality of second anti-slip grooves evenly distributed along the circumference. The outer wall of the top bend of the overhead wire 208 abuts and fits against the inner walls of the semicircular slot 108 and the annular slot 206, respectively. The first anti-slip groove and the second anti-slip groove form an anti-slip fit with the outer wall of the overhead wire 208. The semicircular slot 108 and the annular slot 206 achieve precise positioning and anti-slip of the top of the overhead wire 208.

[0036] The working principle of this embodiment is as follows: First, the operator uses the mounting holes opened on the fixed lug 103 to stably install the base plate 100 at the designated working position on the power tower with the appropriate fasteners, ensuring that the base plate 100 does not shift or shake during the subsequent line-laying operation, laying a solid foundation for the subsequent use of the entire protection device; when installing the overhead wire 208, the top bend of the overhead wire 208 is first suspended in the annular groove 206 opened on the outer ring surface of the wire-clamping roller 205; at this time, it is necessary to ensure that the outer wall of the top bend of the overhead wire 208 is initially in contact with the inner wall of the annular groove 206;

[0037] By applying force through the hinge assembly, a pair of rectangular slide rods 202 are driven to slide upward along the corresponding rectangular slide bases 201. The rectangular slide rods 202 simultaneously drive the rectangular connecting plate 203 to move upward, and the central axis 204 in the middle moves synchronously. The rectangular slider 207 slides along the corresponding rectangular sliding hole 101 on the base plate 100. At the same time, the wire clamping roller 205 moves synchronously towards the semi-circular clamping plate 106 along with the central axis 204 until the outer wall of the top bend of the overhead wire 208 is completely abutted and fitted with the inner wall of the semi-circular groove 108 opened on the inner ring surface of the semi-circular clamping plate 106. At this time, the overhead wire 208 is stably fixed and clamped in the clamping space formed between the wire clamping roller 205 and the semi-circular clamping plate 106, and the first anti-slip groove and the second anti-slip groove both form a reliable anti-slip fit with the outer wall of the overhead wire 208, preventing the overhead wire 208 from sliding or shifting in the clamping space.

[0038] As the cable clamping roller 205 moves the overhead wire 208 towards the semi-circular clamping plate 106, the arc-shaped plate 302 rotates around the horizontal axis 300, ultimately causing the outer arc surfaces of the pair of arc-shaped plates 302 to press against the outer walls of both sides of the overhead wire 208, stably limiting and fixing the two sides of the overhead wire 208 to the base plate 100, further improving the stability of the overhead wire 208. After the overhead wire 208 is completely fixed in the clamping space and its two sides are limited by the arc-shaped plates 302, the operator operates the inner cylinder 404, using the positioning components on the inner cylinder 404 to stably fix and clamp the inner cylinder 404 to the base plate 100, completing the installation and protection operation of the entire high-altitude overhead line protection device for the overhead wire 208, ensuring that the overhead wire 208 is always in a stable and safe state during subsequent power construction.

[0039] Example 2: Based on Example 1, this example adds a worm gear transmission mechanism consisting of a worm wheel 301, a worm 308, and a T-shaped rotating rod 307, as well as a mating structure between the arc plate 302 with an arc groove 303 and the linear groove 105 of the base plate 100. By rotating the T-shaped rotating rod 307, synchronous transmission of each component is achieved, solving the problems of low efficiency of manual adjustment of the hinge assembly and insufficient stability of the overhead wire 208 on both sides in Example 1.

[0040] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the hinge assembly includes a fixed swing arm 304 and a hinge link 305. The fixed swing arm 304 is integrally formed and fixed on the outer wall of the arc plate 302 near the horizontal axis 300. The outer end of the fixed swing arm 304 is hinged to the hinge link 305. The outer end of the hinge link 305 is movably hinged to the bottom end of the rectangular slide bar 202 on the same side to form a linkage structure that can be synchronously transmitted.

[0041] A worm gear 301 is fixedly sleeved on the outer wall of the middle part of the horizontal shaft 300. A horizontally distributed fixed plate 306 is fixed between a pair of fixed side plates 200 above the horizontal shaft 300. A T-shaped rotating rod 307 is rotatably inserted into the middle of the bottom surface of the fixed plate 306. The fixed plate 306 provides stable support for the T-shaped rotating rod 307 to ensure that it does not deviate when rotating. A worm 308 is fixedly sleeved on the outer wall of the middle part of the T-shaped rotating rod 307. The worm 308 meshes with the worm gear 301 and forms a worm gear transmission mechanism. By rotating the T-shaped rotating rod 307, the horizontal shaft 300 can be driven to rotate synchronously. The worm 308 transmits the rotational power of the T-shaped rotating rod 307 to the horizontal shaft 300, realizing speed reduction and torque increase, and improving the convenience and stability of adjustment.

[0042] On both sides of the front of the base plate 100, corresponding to the movement trajectory of the arc plate 302, a pair of arc-shaped notches 104 are provided. The arc-shaped notches 104 can prevent the arc plate 302 from colliding with the base plate 100 when it rotates, ensuring that the arc plate 302 can be properly adjusted to the limit position. A linear groove 105 is provided on the inner wall of each arc-shaped notch 104, and an arc-shaped groove 303 adapted to the outer wall of the overhead wire 208 is provided on the outer arc surface of each arc plate 302. Several third anti-slip grooves are evenly distributed along the arc direction on the wall. Each arc-shaped groove 303 cooperates with the linear groove 105 on the same side to limit and fix the side wall of the overhead wire 208. The third anti-slip groove and the outer wall of the overhead wire 208 form an anti-slip fit. The linear groove 105 and the arc-shaped groove 303 cooperate to form a double limit and fixation on the side wall of the overhead wire 208, which enhances the stability of the limit on both sides of the overhead wire 208 and prevents the overhead wire 208 from shifting to the side.

[0043] The working principle of this embodiment is as follows: The operator manually rotates the T-shaped rotary rod 307, which drives the worm gear 308 to rotate synchronously. The worm gear 308 then meshes with and drives the worm wheel 301 and the horizontal shaft 300 to rotate synchronously. The pair of arc-shaped plates 302 at both ends of the worm gear 308 rotate synchronously with the horizontal shaft 300. At the same time, the fixed swing arm 304 also rotates with the arc-shaped plates 302. The fixed swing arm 304 will drive the rectangular slide bar 202 to slide along the corresponding rectangular slide block 201 through the hinged connecting rod 305.

[0044] When the rectangular slide bar 202 slides upward, it drives the rectangular connecting plate 203 to move upward synchronously, and the central shaft 204 moves accordingly. The central shaft 204 will drive the rectangular slider 207 to slide upward along the rectangular sliding hole 101. At the same time, the wire clamping roller 205 moves synchronously towards the semi-circular clamping plate 106 along with the central shaft 204 until the outer wall of the top bend of the overhead wire 208 completely abuts against the inner wall of the semi-circular groove 108 on the inner ring surface of the semi-circular clamping plate 106, forming a clamping space.

[0045] During the rotation of the arc plate 302 with the horizontal axis 300, when the arc plate 302 rotates to abut against the outer walls on both sides of the overhead wire 208, the arc-shaped slot 303 of the arc plate 302 will precisely cooperate with the linear slot 105 of the bottom plate 100 on the same side, forming a double limiting and locking fixation on the side wall of the overhead wire 208, and the third anti-slip groove forms an anti-slip cooperation with the outer wall of the overhead wire 208, further improving the limiting stability;

[0046] After the top of the overhead wire 208 is engaged between the wire clamping roller 205 and the semi-circular clamping plate 106, and both sides are limited and fixed by the arc-shaped clamping groove 303 and the linear clamping groove 105, the operator operates the inner cylinder 404 and fixes the inner cylinder 404 onto the base plate 100 through the positioning component, thus completing the installation and protection of the overhead wire 208 by the entire device.

[0047] Example 3: Based on Example 2, this example adds a pin hole positioning structure consisting of a T-shaped pin 407 and a positioning pin hole 102, as well as a sleeve 401 with an annular groove 402 and a connecting groove 403 and an inner cylinder 404 with a V-shaped clamping plate 409 and a limiting pin 410. The inner cylinder 404 is accurately positioned by rotating and pushing the knob 405, which solves the problems of inconvenient operation of the positioning component and easy loosening of the wire clamping roller 205 and the arc plate 302 after fixing in Example 2.

[0048] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the positioning component includes a T-pin 407. A positioning pin hole 102 is provided on the base plate 100 at a position corresponding to the movement trajectory of the inner cylinder 404. A knob 405 for easy gripping and rotation is integrally formed and fixed at the outer end of the inner cylinder 404. A T-pin 407 is integrally formed and fixed at the inner end of the inner cylinder 404. The outer end of the T-pin 407 can be slidably inserted into the positioning pin hole 102 to realize the positioning and fixing of the inner cylinder 404 and the base plate 100.

[0049] The inner annular surface of the sleeve 401 is provided with a pair of annular grooves 402 spaced apart along the axial direction, and a pair of through grooves 403 are provided between the pair of annular grooves 402 along the axial direction. The two ends of the through grooves 403 are respectively connected to the corresponding annular grooves 402. A pair of limiting pin holes 406 are provided on the outer wall of the inner cylinder 404 at the position corresponding to the through grooves 403. The limiting pin holes 406 are provided radially through the inner cylinder 404.

[0050] A connecting shaft 408 is axially fixed inside the inner cylinder 404. A V-shaped clamping plate 409 is hinged to the outer wall of the middle part of the connecting shaft 408. A tension spring 411 is fixed between the inner sidewalls of the opening of the V-shaped clamping plate 409. The V-shaped clamping plate 409 maintains an opening tendency under the action of the tension spring 411, so that the limiting pin 410 abuts tightly against the inner wall of the annular groove 402, improving the positioning stability. The tension spring 411 is always in a stretched state, providing an opening tendency for the V-shaped clamping plate 409. The outer walls of both ends of the V-shaped clamping plate 409 are integrally formed. A pair of limiting pins 410 are fixedly provided. The limiting pins 410 cooperate with the annular groove 402 and the connecting groove 403 to realize the sliding and positioning of the inner cylinder 404 in the sleeve 401, and restrict the axial sliding and rotation of the inner cylinder 404. It is the core component for the dual positioning of the inner cylinder 404. Each limiting pin 410 slides through the limiting pin hole 406 on the same side and abuts in the annular groove 402. Through the cooperation of the limiting pins 410 with the annular groove 402 and the connecting groove 403, the sliding and positioning of the inner cylinder 404 in the sleeve 401 is realized.

[0051] The working principle of this embodiment is as follows:

[0052] Before operation, it is necessary to confirm that: the pair of limiting pins 410 on the outer wall of the inner cylinder 404 are in the annular groove 402 on the right side of the inner ring surface of the sleeve 401, and the limiting pins 410 and the communicating groove 403 on the sleeve 401 are misaligned; the T-shaped pin 407 at the inner end of the inner cylinder 404 is not inserted into the positioning pin hole 102 of the base plate 100, to ensure that the inner cylinder 404 can rotate and slide normally in the sleeve 401.

[0053] Step 1: Rotate knob 405 to align with connecting slot 403;

[0054] The operator holds and rotates the knob 405, which drives the inner cylinder 404 to rotate synchronously. This, in turn, causes the connecting shaft 408, the V-shaped clamp 409, and a pair of limiting pins 410 to rotate in the annular groove 402 on the right side of the sleeve 401. The knob 405 is rotated continuously until the pair of limiting pins 410 are fully aligned with the pair of connecting grooves 403 on the sleeve 401. At this point, the rotation is stopped, and preparation is made for the sliding operation of the inner cylinder 404.

[0055] Second step: Push knob 405 and insert T-pin 407;

[0056] Keeping the limiting pin 410 aligned with the connecting groove 403, push the knob 405 towards the base plate 100. The knob 405 causes the inner cylinder 404 to slide inward along the axial direction of the sleeve 401. Simultaneously, the limiting pin 410 on the outer wall of the inner cylinder 404 slides along the connecting groove 403 from the right annular groove 402 to the left annular groove 402. At the same time, the T-shaped pin 407 at the inner end of the inner cylinder 404 moves with the inner cylinder 404 and gradually approaches the corresponding positioning pin hole 102 on the base plate 100. Continue to push the knob 405 until the limiting pin 410 is completely slid into the left annular groove 402. At this time, the outer end of the T-shaped pin 407 just slides into the positioning pin hole 102, realizing the initial pin hole positioning of the inner cylinder 404 and the base plate 100.

[0057] Third step: Rotate knob 405 again to lock limit pin 410;

[0058] With the T-pin 407 inserted into the positioning pin hole 102, the knob 405 is rotated again, causing the inner cylinder 404, connecting shaft 408, and V-shaped clamp 409 to rotate synchronously. This causes the limiting pins 410 at both ends of the V-shaped clamp 409 to rotate within the left annular groove 402 until the limiting pins 410 are completely misaligned with the connecting groove 403. At this point, due to the tension of the tension spring 411, the V-shaped clamp 409 remains open, and the limiting pins 410 are tightly pressed against the inner wall of the left annular groove 402, preventing them from sliding into the connecting groove 403. Meanwhile, the T-pin 407 is stably inserted into the positioning pin hole 102. This double positioning structure ensures that the inner cylinder 404 is completely fixed within the sleeve 401, preventing axial sliding or rotation.

[0059] Final fixation effect: Ensures the stability of the 208 overhead power line installation;

[0060] After the inner cylinder 404 is completely fixed, it forms a rigid connection with the rectangular connecting plate 203 through the fixed connecting plate 400, thereby restricting the sliding of the rectangular connecting plate 203 and the rectangular sliding rod 202. At the same time, the central shaft 204, the wire clamping roller 205 on the rectangular connecting plate 203, and the arc plate 302 linked with the rectangular sliding rod 202 are all fixed in the designated position and cannot be adjusted or rotated. This ensures that the overhead wire 208 is stably clamped in the clamping space, avoiding wire displacement due to loose parts during construction and ensuring the long-term stability of the fixed installation of the overhead wire 208.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
