Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage power transmission network erection, and particularly relates to a spacer rod conveying device for high-voltage power transmission network erection. BACKGROUND

[0002] The spacer rod refers to a fitting installed on split conductors to fix the distance between the split conductors, so as to prevent the conductors from whipping each other, inhibit the wind vibration and sub-span oscillation.

[0003] In the prior art, when the spacer rod is conveyed, a pulley block with hooks and a rope are usually used for conveying, and when installation is required, a worker unties the corresponding rope on the spacer rod, and then takes down the spacer rod for installation. The high-voltage line is usually located in the air, and the wind force is relatively large. The rope conveying mode is easy to cause entanglement. Once the rope is not tightly bound, the spacer rod may fall from the air, which has great safety hazards. Since the pulley block pulls multiple spacer rods through the rope, the cable provided with the pulley block is in a downwardly tight state under the gravity of the multiple spacer rods, and thus the worker is more laborious when installing the spacer rod on the cable.

[0036] In use, the worker puts the upper lock 104 and the lower lock 106 on the corresponding four cables, and makes the roller 107 on the cable, then turns the bearing rod 202 counterclockwise in turn, and the worker hangs the spacer on the bearing rod 202, the bearing rod 202 counterclockwise will make the bearing torsion spring 203 store energy, the bearing rod 202 clockwise resets under the action of the bearing torsion spring 203, then the worker hangs the spacer on the four bearing rods 202 in turn, after the mounting is completed, the worker moves the device to the position where the spacer needs to be installed, when moving to the installation position, the worker opens the corresponding bearing rod 202 by lifting the spacer, then takes down the spacer from the bearing rod 202 to start installation, after the spacer is installed, the device can be taken down; the spacer is hung on the connecting rod in a way, which solves the problem of winding in the existing technology, and is safer, and will not fall off because of not being tied tightly; and the device is installed on the four cables, which has a certain folding effect on the four cables, and is more convenient for the worker to install the spacer on the cable.

[0037] As Figure 2 and Figure 5As shown, the device further comprises a speed reduction mechanism for manual speed reduction, the speed reduction mechanism is mounted on the upper lock buckle 104, the speed reduction mechanism comprises a fixed shell 3, a speed reduction frame 301, a speed reduction rod 302, a middle clamping block 303, a side clamping block 304, a lower contact plate 305 and an upper contact plate 306, the upper lock buckle 104 is fixedly connected with the fixed shell 3, the fixed shell 3 is fixedly connected with the speed reduction frame 301, the speed reduction frame 301 is slidingly connected with the speed reduction rod 302, the upper part of the speed reduction rod 302 is provided with an annular handle convenient for workers to hold, the lower end of the speed reduction rod 302 is fixedly connected with the middle clamping block 303, the fixed shell 3 is rotatably connected with two symmetrical side clamping blocks 304, the inner sides of the middle clamping block 303 and the side clamping block 304 are provided with rubber pads, the upper sides of the two side clamping blocks 304 are provided with two symmetrical lower contact plates 305, and the two sides of the middle clamping block 303 are provided with two symmetrical upper contact plates 306. The middle clamping block 303 drives the two side clamping blocks 304 to rotate inward to clamp the cable through the upper contact plate 306 and the lower contact plate 305.

[0038] The middle part of the cable is usually lower than the two sides in height, which may cause a faster moving speed when moving to the middle part of the cable. When it is necessary to reduce the moving speed of the device on the cable, the worker presses the speed reduction rod 302 downward to make the middle clamping block 303 contact with the cable, and at the same time, the upper contact plates 306 on the two sides press the lower contact plates 305 downward, which drives the two side clamping blocks 304 to move towards the cable, thereby reducing the moving speed of the device through the friction between the middle clamping block 303, the side clamping block 304 and the cable. The worker can clamp the cable by pressing the speed reduction rod 302, so as to achieve the effect of speed reduction and avoid the situation that the device moves too fast and is not easy to control.

[0039] As shown in the drawings, Figure 5 The device further comprises a locking mechanism for fixing the device, the locking mechanism is connected with the speed reduction rod 302, and the locking mechanism comprises a limiting convex ring 4, a reset spring 401, a limiting rod 402, a limiting spring 403 and a limiting convex block 404.

[0040] When the workers install the spacer bar, the device can move under the action of external forces such as wind and gravity, thereby affecting the normal installation of the spacer bar by the workers, or the workers need to manually pull the device back, reducing the installation efficiency; when it is necessary to lock the device at a fixed position, the worker presses the speed reducer 302 downward, the speed reducer 302 drives the limiting convex ring 4 to move downward and compresses the reset spring 401, when the limiting convex ring 4 contacts the limiting convex block 404, the limiting rod 402 is extruded, the limiting rod 402 moves toward the fixed shell 3 and compresses the limiting spring 403, when the limiting convex ring 4 moves below the limiting convex block 404, the limiting rod 402 resets under the pushing of the limiting spring 403, so that the limiting convex block 404 blocks the speed reducer 302 upward reset through the limiting convex ring 4, so that the middle clamp block 303 and the side clamp block 304 always maintain the state of clamping the cable, thereby realizing the locking of the device; when it is necessary to release the locking, the worker pushes the limiting rod 402 toward the fixed shell 3, so that the limiting convex block 404 cancels the limiting of the limiting convex ring 4, the reset spring 401 drives the speed reducer 302 to move upward and reset through the limiting convex ring 4, so that the middle clamp block 303 and the side clamp block 304 are out of contact with the cable, and then the limiting rod 402 is released, the limiting rod 402 resets away from the fixed shell 3 under the pushing of the limiting spring 403; the speed reducer 302 cooperates with the limiting convex ring 4 and the limiting convex block 404 to make the middle clamp block 303 and the side clamp block 304 always maintain the state of clamping the cable, so as to lock the device at a fixed position, preventing the device from moving under the action of external forces and affecting the normal installation of the spacer bar.

[0041] Embodiment 2

[0042] On the basis of embodiment 1, as shown in Figure 2 and Figure 6 , further comprising a limiting mechanism for limiting the left and right swinging of the spacer bar, the limiting mechanism is installed on the bearing frame 2, and the limiting mechanism comprises a middle blocking rod 5, a middle blocking block 501, a side blocking rod 502, a side blocking plate 503, a side blocking block 504 and a blocking block spring 5041, the middle blocking rod 5 is fixedly connected to the middle round rod of the bearing frame 2, two middle blocking blocks 501 are symmetrically fixedly connected to the lower end of the middle blocking rod 5, two side blocking rods 502 are symmetrically fixedly connected to the round rods on the two sides of the bearing frame 2, two side blocking plates 503 are fixedly connected to the lower side of the side blocking rod 502, the heights of the two side blocking plates 503 on the same side blocking rod 502 are different, a side blocking block 504 is slidably connected to each side blocking plate 503, and the side blocking block 504 and the side blocking plate 503 are elastically connected through the blocking block spring 5041.

[0043] Because the high-voltage cable is generally high in height and the wind force is large, the spacer rod can swing, and large swing of the spacer rod not only affects the normal movement on the cable, but also has certain safety hazards; after the spacer rod is hung on the bearing rod 202, the middle block 501 and the side block 504 can limit the lower side of the spacer rod, preventing the spacer rod from swinging greatly and reducing safety hazards; by limiting the lower side of the spacer rod through the middle block 501 and the side block 504, the spacer rod can be prevented from swinging greatly, and safety hazards can be reduced.

[0044] As shown in Figure 2 , Figure 5 and Figure 6 , it also includes a self-locking mechanism for automatically reducing speed when the wind force is large, the self-locking mechanism is connected with the side block 504, and the self-locking mechanism includes a wire tube 6, a pull wire 601, a fixed tube 602, a self-locking rod 603 and a self-locking nut 604. The two side blocks 502 on the two sides and the main straight rod 1 are symmetrically and jointly fixed with two wire tubes 6, the wire tube 6 is provided with the pull wire 601, the wire tube 6 is used for installing and guiding the pull wire 601, the two side blocks 503 on the same side are jointly fixed with the fixed tube 602, the fixed tube 602 is located between the two side blocks 504, the lower side of the pull wire 601 passes through the fixed tube 602, the pull wire 601 is fixed with the two side blocks 503 on the same side, the pull wire 601 is located on the side where the two side blocks 503 are close to each other, the upper side of the pull wire 601 is fixed with the self-locking rod 603, the self-locking rod 603 is inserted into the speed reduction rod 302 on the same side, and the end of the self-locking rod 603 away from the pull wire 601 is threadedly connected with the self-locking nut 604.

[0045] When the wind force drives the spacer rod to swing, the spacer rod will extrude one side of the side block 504, so that the side block 504 moves and compresses the corresponding block spring 5041. When the side block 504 moves, a pulling force is applied to the lower end of the pull wire 601, so that a pulling force is applied to the upper end of the pull wire 601. The upper end of the pull wire 601 and the self-locking rod 603 drive the speed reduction rod 302 to move downward, so that the middle clamp block 303 and the side clamp block 304 contact the cable, the moving speed of the device is reduced, so that the device automatically reduces speed when the wind force is large, preventing the device from moving too fast under the push of the wind force, causing collision or difficulty in control by workers, and reducing safety hazards. When automatic speed reduction is not needed, the self-locking nut 604 can be manually removed from the self-locking rod 603, then the self-locking rod 603 is pulled out of the speed reduction rod 302, and then the self-locking nut 604 is tightened on the self-locking rod 603 to prevent loss.

[0046] As shown in Figure 1 and Figure 7The spacer rod is also shown, and further comprises a swing limiting mechanism for limiting the front and back swing of the spacer rod, the swing limiting mechanism being connected with the left connecting block 101 and the right connecting block 102, the swing limiting mechanism comprising a swing limiting bracket 7, a swing limiting sliding sleeve 701, a swing limiting bent rod 702, a swing limiting stopper 703, a swing limiting cam 704, a swing limiting connecting rod 705, a lifting rod 706 and a lifting tension spring 707, the end of the bearing rod 202 away from the rotation shaft of the bearing rod 202 is magnetically matched with the corresponding bearing block 201 and the right connecting block 102, when the right end of the bearing rod 202 is clamped in the groove on the bearing block 201 and the right connecting block 102, the bearing rod 202 is attracted by magnetic force, the swing limiting bracket 7 is fixed on the left connecting block 101 and the right connecting block 102, the swing limiting sliding sleeve 701 is slidingly connected on the swing limiting bracket 7, the swing limiting bent rod 702 is fixed on the swing limiting sliding sleeve 701, two swing limiting stoppers 703 are symmetrically and coaxially connected on the lower side of the swing limiting bracket 7, the swing limiting cams 704 are fixed on the rotation shafts of the swing limiting stoppers 703, the swing limiting bent rod 702 drives the swing limiting stoppers 703 to swing upward through the swing limiting cams 704 so as to facilitate the taking out of the spacer rod, the swing limiting connecting rod 705 is fixed on the upper side of the swing limiting bent rod 702, the lifting rod 706 is slidingly connected on the three bearing blocks 201 and the right connecting block 102, the lifting rod 706 is in contact with the lower surface of the swing limiting connecting rod 705, the lifting rod 706 passes through the groove on the corresponding bearing block 201 or the right connecting block 102, the bearing rod 202 extrudes the lifting rod 706 downward, the lifting tension spring 707 is connected between the lifting rod 706 and the corresponding bearing block 201 and the right connecting block 102, through the magnetic matching between the bearing rod 202 and the corresponding bearing block 201 and the right connecting block 102, the lifting rod 706 is in the state of being extruded and the lifting tension spring 707 being stretched.

[0047] The bearing rod 202 is magnetically matched with the corresponding bearing block 201 and the right joint block 102. When the worker needs to open and place or remove the spacer rod, the bearing rod 202 is opened by the worker against the magnetic force of the corresponding bearing block 201 and the right joint block 102, so that the bearing rod 202 no longer limits the upward movement of the lifting rod 706, and the lifting rod 706 moves upward under the action of the lifting tension spring 707. When the lifting rod 706 moves upward, the limit swing connecting rod 705 drives the limit swing sleeve 701 to move upward, and in turn drives the limit swing bent rod 702 to move upward. The upward movement of the limit swing bent rod 702 drives the limit swing cam 704 to rotate upward, so that the limit swing stop rod 703 is driven by the limit swing cam 704 to rotate upward to a vertical state, so as to facilitate the removal or placement of the spacer rod. After the spacer rod is removed or placed, the bearing rod 202 is rotated to reset and presses the corresponding lifting rod 706 downward, so that the lifting rod 706 no longer drives the limit swing connecting rod 705 to move upward, and the limit swing sleeve 701 and the limit swing bent rod 702 move downward to reset, and then the limit swing stop rod 703 is rotated to a horizontal state. The limit swing stop rod 703 can limit the forward and backward swinging of the spacer rod to a certain extent in the horizontal state, and the worker can apply pressure to the limit swing stop plate to increase the stability of the limit swing stop plate when limiting the swinging of the spacer rod.

[0048] Embodiment 3

[0049] On the basis of embodiment 2, as shown in Figure 2 and 9 Further comprising an adaptive mechanism for adapting the distance between the left and right cables, the adaptive mechanism is installed on the right joint block 102, and the adaptive mechanism comprises an adjusting block 8, a spring rod 801 and an adjusting clamp plate 802. Ten through holes are symmetrically formed on the left and right sides of the right joint block 102, and the adjusting block 8 is arranged on the right joint block 102. The right side of the connecting pipe 1021 is fixedly connected with the adjusting block 8. Two spring rods 801 are symmetrically arranged on the adjusting block 8 and are respectively inserted into the through holes on the left and right sides of the right joint block 102 to be fixed. Two adjusting clamp plates 802 are symmetrically and slidably connected to the right joint block 102. The adjusting clamp plate 802 is provided with five protrusions corresponding to the through holes on the right joint block 102.

[0050] When it is necessary to adjust the device according to the distance between the left and right cables, the two adjusting clamp plates 802 are pressed towards each other, and the two spring rods 801 are compressed into the adjusting block 8 through the two adjusting clamp plates 802, so that the spring rods 801 are moved out of the through holes of the right joint block 102. Then the upper connecting rod 103 can be driven by the adjusting block 8 to move left and right. When the adjustment is appropriate, the adjusting clamp plate 802 is released, and the spring rod 801 automatically extends and is clamped in the corresponding through hole of the right joint block 102, so that the adjustment is completed.
