As shown in fig. 1, the invention provides a high-altitude cable multi-position grounding device, which comprises an operating rod 1, wherein one end of the operating rod 1 is connected with a fixed platform 2, the other end of the operating rod 1 is connected with an operating mechanism 3, and a clamping mechanism 4 for clamping a plurality of high-altitude cables is arranged on the fixed platform 2;
the clamping mechanism 4 comprises a lifting table 8 connected with the surface of one side, far away from the operating rod 1, of the fixed table 2, the surfaces of two ends of the lifting table 8 are respectively connected with a plurality of clamping devices 5 used for clamping cables with different heights, a sliding embedding groove 801 is formed in the center of the lifting table 8, and a clamping trigger 6 connected with the operating mechanism 3 and used for driving each clamping device 5 to perform clamping operation is arranged in the sliding embedding groove 801;
the lifting platform 8 drives the plurality of clampers 5 to ascend, the operating mechanism 3 drives the clamping trigger 6 to slide along the sliding embedding groove 801, so that the plurality of clampers 5 are controlled to be flush with a plurality of cables in one-to-one correspondence respectively, and the clamping trigger 6 drives the clampers 5 flush with the cables to clamp the cables.
When the grounding device is used, air can be directly injected into the lifting platform 8 through the components on the operating mechanism 3 to drive the clamp holder 5 to lift, when the clamp holder 5 is lifted to be in contact with a first cable, the operating mechanism 3 can be driven to drive the clamping trigger 6 to slide along the sliding embedding groove 801, the sliding clamping trigger 6 can control the position of the first clamp holder 5 and clamp the cable, after the first cable is clamped, air injection operation can be performed again to lift the second clamp holder 5, then the second cable is fixed according to the operation, and the process is repeated until all the cables are fixed.
As shown in fig. 1 and 5, the clamper 5 comprises a transfer frame 501 and a limiting column 502, wherein the transfer frame 501 is connected with the surface of the lifting platform 8, an inclined clamping block 7 is connected to the transfer frame 501 through the limiting column 502, and a driving piece 503 is connected to one end, close to the clamping trigger 6, of the inclined clamping block 7;
the clamping trigger 6 comprises a limiting frame 9 which is slidably connected in a sliding embedding groove 801, and a triggering clamping strip 601 for driving the driving sheet 503 to clamp the inclined clamping block 7 is arranged on the surface of the limiting frame 9;
the limiting frame 9 slides along the sliding-embedded groove 801, limits the position of the inclined clamping block 7, and drives the driving piece 503 to move through the triggering clamping strip 601 to clamp the inclined clamping block 7.
When the limiting frame 9 slides in the sliding-fit groove 801, once the clamping bar 601 is triggered to slide onto the driving piece 503, the limiting frame 9 limits the position of the first inclined clamping block 7 (i.e. the air is injected again and the inclined clamping block 7 does not rise), if the limiting frame 9 continues to move, the driving piece 503 is pushed by the triggering clamping bar 601 moving along with the limiting frame 9, so as to clamp the inclined clamping block 7, and then if a subsequent cable needs to be clamped, the operation can be continued according to the above operation.
As shown in fig. 1 and 7, the inclined clamping block 7 includes a fixed inclined block 701 connected to the transfer rack 501 and inclined toward one side of the fixed rack 2, a rotating inclined block 702 connected to the transfer rack 501 through a limiting column 502 is disposed on one side of the fixed inclined block 701 away from the fixed rack 2, the driving plate 503 is mounted at one end of the rotating inclined block 702 close to the limiting rack 9, an anti-opening column 703 is mounted at the other end of the rotating inclined block 702 close to the surface of the fixed inclined block 701, an anti-column clamping frame 704 for clamping the anti-opening column 703 is mounted on the surface of the fixed inclined block 701 at a position corresponding to the anti-opening column 703, a plurality of half arc grooves 709 are formed on the surface of the rotating inclined block 702, and a plurality of half arc grooves 709 are also formed on the fixed inclined block 701, and the half arc grooves 709 are arranged to make cable fixing and clamping firmer and prevent a sliding phenomenon easily occurring.
When the cable is clamped between the rotating inclined block 702 and the fixed inclined block 701, the anti-opening column 703 is directly clamped on the anti-column clamping frame 704, so that the first cable is not easily loosened between the rotating inclined block 702 and the fixed inclined block 701.
As shown in fig. 1, 3 and 7, the anti-column-jamming frame 704 is composed of two card-fixing frames 705 symmetrically installed on the surface of the fixed sloping block 701, the anti-opening column 703 includes a pushing block 706 and an embedding strip 707 located between the two card-fixing frames 705 and connected with the rotating sloping block 702, and both ends of the embedding strip 707 are connected with an embedding anti-column 708 embedded in the card-fixing frame 705 through the pushing block 706.
The specific process of the anti-separation column 703 being clamped on the anti-column clamping frame 704 is that when the rotating inclined block 702 rotates to contact the fixed inclined block 701, the embedded bar 707 is located between the two clamping frames 705 (the specific structure of the clamping frame 705 can be a U-shaped mechanism as shown in fig. 7), and the embedded anti-column 708 is directly clamped in the U-shaped opening of the clamping frame 705 under the action of the connecting and pushing block 706 (a spring can be selected).
As shown in fig. 3, the swash block 702 includes a main swash frame 710 connected to the transfer frame 501 through a limiting post 502, a step slide groove 711 is formed in the main swash frame 710, a movable pressing block 712 is slidably connected to the step slide groove 711, and a guide swash spring 713 is installed between the main swash frame 710 and the movable pressing block 712.
When the first cable is connected and clamped, gas can be injected into the lifting platform 8 again, so that the second inclined clamping block 7 is lifted to be in contact with the second cable, and when the second inclined clamping block 7 is lifted, the transfer frame 501 directly pushes the fixed inclined block 701 and the rotating inclined block 702 to ascend simultaneously, if the cable is higher than the first cable and is closer to the limiting frame 9, the second cable firstly contacts the lifted rotating inclined block 702, namely the second cable firstly contacts the guiding inclined spring plate 713, then the transfer frame 501 is continuously lifted, the second cable slides along the inclined surface of the guiding inclined spring plate 713 and bends the guiding inclined spring plate 713, and the movable pressing block 712 is pushed in the process of bending the guiding inclined spring plate 713, so that the second cable moves towards the main inclined frame 710 along the stepped sliding groove 711, namely the length of the whole rotating inclined block 702 can be shortened, and then the second cable can easily pass through the rotating inclined block 702 without being blocked by the rotating inclined block 702, so that the second cable cannot be blocked The situation of clamping or tearing off the second cable occurs, and the installation performance is high.
When the second cable passes through the rotating inclined block 702, the second cable contacts the fixed inclined block 701, and then the cable is clamped continuously according to the operation.
As shown in fig. 1, an extension wire 714 is installed on a side wall of the fixed swash block 701, the extension wire 714 includes a fixed wire 715 connected to the fixed swash block 701, a spiral connection wire 716 is installed at an end of the fixed wire 715 far from the fixed swash block 701, and a ground connection block 717 connected to the fixed base 2 is installed at an end of the spiral connection wire 716 far from the fixed wire 715.
When the transfer frame 501 is lifted, the fixed conducting wire 715 is pulled by the fixed inclined block 701 to be lifted together, and the lifted fixed conducting wire 715 gradually straightens the spiral connecting wire 716, i.e. the extension conducting wire 714 has a free variation which can be lengthened along with the lifting of the transfer frame 501, so that the connection between the whole extension conducting wire 714 and the grounding wire is not affected.
As shown in fig. 1, 5 and 6, the lifting table 8 includes a plurality of lifting plates 802, the surfaces of which are provided with sliding insertion grooves 801 and are connected with the transfer frame 501, the surfaces of both ends of the lifting plates 802 are provided with pneumatic cylinders 803 connected with the fixed table 2, pneumatic columns 804 are movably connected in the pneumatic cylinders 803, one ends of the pneumatic columns 804 far away from the pneumatic cylinders 803 are provided with fixed blocks 805 connected with the lifting plates 802, and the surfaces of the fixed blocks 805 are provided with a plurality of long blocks 806.
The lifting table 8 can achieve the purpose of lifting the inclined clamping block 7, when the lifting table is implemented, a user only presses the elastic block 101 to inject gas into the pneumatic cylinder 803, after the pressure in the pneumatic cylinder 803 is increased, the pneumatic column 804 pushes the fixed block 805 and the lifting plate 802 to ascend together, and the ascending lifting plate 802 drives the inclined clamping block 7 to ascend together.
As shown in fig. 1, 2, 5 and 6, the limiting frame 9 includes a sliding block 901 slidably connected in a sliding caulking groove 801, a plurality of short blocks 902 are mounted on both side surfaces of the sliding block 901, the short blocks 902 are located between two adjacent long blocks 806, an caulking groove 903 in which a rack is mounted is formed at one end of the sliding block 901, a tooth column 904 connected with the operating mechanism 3 and used for driving the sliding block 901 to slide along the sliding caulking groove 801 is arranged in the caulking groove 903, a moving frame 905 connected with the lifting plate 802 is mounted at the other end of the sliding block 901, and a side wall of the moving frame 905 is directly connected with the trigger clamping bar 601;
the tooth column 904 drives the sliding block 901 to drive the moving rack 905 to slide back and forth along the sliding embedded groove 801, so that the driving piece 503 moves up and down along the surface of the triggered clamping bar 601 sliding along with the moving rack 905, and the inclined clamping block 7 is clamped and opened periodically.
When the first inclined clamping block 7 rises to be in contact with the first cable, the situation that the first cable is torn off due to the fact that a user needs to limit the pneumatic column 804 on the first pneumatic cylinder 803 to avoid subsequent gas injection operation is generated, in practice, the user simply rotates the rotating sleeve 305 to rotate the toothed column 904, and then the rotating toothed column 904 engages the driving rack to push the sliding block 901 forward (as shown in fig. 1), when the slider 901 slides to the first air cylinder 803, the short blocks 902 on the two side surfaces of the slider 901 will contact the long blocks 806 on the first fixed block 805, the first fixed block 805 and the first pneumatic cylinder 803 are limited by the contact mode, and since there are multiple long blocks 806 on each fixed block 805, no matter where the slider 901 slides, the short block 902 on the slider 901 can contact the corresponding long block 806 on the fixed block 805.
When the first pneumatic cylinder 803 is limited, the sliding block 901 continues to slide, and when the sliding trigger clamping bar 601 contacts the driving piece 503, the driving piece 503 is pushed to move towards the side away from the sliding block 901, i.e. the cable is clamped.
As shown in fig. 2, the triggered clamping bar 601 includes a first oblique guide block 602 connected to a side wall of one end of the movable frame 905 and a second oblique guide block 603 connected to a side wall of the other end of the movable frame 905, the width of the first oblique guide block 602 is set to be a linearly decreasing trend from bottom to top, the width of the second oblique guide block 603 is set to be a linearly increasing trend from bottom to top, the pressing bars 604 for pressing the driving plate 503 are installed on the side walls of the ends with the smallest width of the first oblique guide block 602 and the second oblique guide block 603, and the two ends of the first oblique guide block 602 and the second oblique guide block 603 on the same side of the movable frame 905 are as shown in fig. 2.
Taking fig. 1 as an example, during the clamping operation, the driving plate 503 is in contact with the first inclined guiding block 602 (the sliding block 901 moves forward), that is, when the driving plate 503 slides on the inclined surface of the first inclined guiding block 602, the driving plate 503 moves gradually towards the side away from the moving frame 905, that is, the driving plate 503 drives the inclined rotating block 702 to move towards the inclined fixed block 701, and after the inclined fixed block 701 and the inclined rotating block 702 are in full contact, the pressing bar 604 presses the driving plate 503 on the inclined rotating block 702, so that the inclined rotating block 702 does not loosen, and the subsequent operations are also performed.
When the releasing operation is performed, the driving plate 503 is in contact with the second inclined guide 603, (because the slider 901 moves backward), the second inclined guide 603 contacts the highest position of the driving plate 503, and then the moving frame 905 and the second inclined guide 603, which slide gradually, move the driving plate 503 in a direction away from the fixed inclined block 701, so that the cable is released.
In the present invention, besides the inclined clamping block 7 and the extension wire 714 are made of metal material, other components can be made of rubber or light plastic material, so that the weight of the whole grounding mechanism can be sufficiently reduced to avoid the situation that the cable is broken due to the heavy device.
As shown in fig. 1 and 4, the operating mechanism 3 includes the air bag 301 that cup joints the inner wall of the operating rod 1, the lateral wall of the air bag 301 is equipped with the annular groove 302 install in the annular groove 302 and run through the operating rod 1 to external briquetting 303, the bullet piece 101 of being connected with briquetting 303 is installed to the lateral wall of the operating rod 1 the rotation axle sleeve 304 has been cup jointed in the air bag 301, the one end of rotation axle sleeve 304 is equipped with the swivel mount 305 of being connected with the operating rod 1, the other end inner wall of rotation axle sleeve 304 has cup jointed the removal post 306, it runs through rotation axle sleeve 304 and extends to in the caulking groove 903 and is connected with the tooth post 904 to remove the post 306, be equipped with the pipe 307 that communicates with pneumatic cylinder 803 on the air bag 301.
When a user performs an inflation operation, the user only presses the elastic block 101 to repeatedly press the pressing block 303 and the air pressing bag 301, so that the air in the air pressing bag 301 is simultaneously introduced into the plurality of pneumatic cylinders 803 through the conduit 307 (in order to enable a subsequent operation to be performed normally, an air release port may be disposed on the air pressing bag 301), and when the inflation operation is performed, the user may drive the rotating shaft sleeve 304 by rotating the rotating sleeve 305 (a quadrangular sliding slot is disposed in the rotating shaft sleeve 304), and the rotating shaft sleeve 304 may drive the moving column 306 to rotate the toothed column 904, and the moving column 306 may slide up and down in the rotating shaft sleeve 304, because the moving column 306 is connected with the toothed column 904, which needs to move along with the sliding block 901.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
