Description

Technical Field

[0002] High-altitude power cables are common in daily life. They are mainly used to transmit large amounts of electrical energy, avoid ground space limitations and prevent cable damage. At present, the top of the pole is generally used to install power cables, and the location where the power cables and the poles are installed is prone to failure. Therefore, maintenance personnel are generally required to use a lifting device to inspect and repair the power cables and the cables at the location where the poles are installed. At present, the lifting device generally adopts a foot buckle or a ladder. When the maintenance personnel use the foot buckle to lift, generally the arc-shaped part on the foot buckle is firstly made to form an inclined clamping contact with the outer end of the pole, so that the foot buckle and the pole are restricted and installed, and then the maintenance personnel are made to lift along the pole. When the maintenance personnel use the ladder to lift, the bottom end of the ladder is firstly made to contact with the ground, and then the top end of the ladder is made to contact with the outer end of the pole, and the ladder is made to be inclined, and then the maintenance personnel climb the ladder to lift; However, such lifting movement will cause greater labor intensity, and the ladder or foot buckle is prone to slip when in contact with the pole, resulting in a high probability of falling for the maintenance personnel performing the lifting, and poor safety.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.16 As shown, a safety lifting device for high-altitude power cable maintenance is provided, including a box body 1, a plurality of multi-section telescopic rods 4 are equidistantly installed between the front end of the box body 1 and the rear end of a first box body 53 which is arranged transversely and located at the front side of the box body 1, the plurality of multi-section telescopic rods 4 are used in cooperation to make the box body 1 and the first box body 53 movably connected, and a first bidirectional screw 536 which passes through two first movable seats 532 and is threadedly connected to the two first movable seats 532 is rotatably connected to the inside of the first box body 53, and the two first movable seats 532 are moved relative to each other by the first bidirectional screw 536, and then the output shaft of the second driving device whose fixed part is arranged at the right end of the first box body 53 is connected to the first bidirectional screw 536, and the first bidirectional screw 536 is driven to rotate by the second driving device, and the second driving device can adopt a third motor 535; Two first movable seats 532 extending from the front side of the first box body 53 are symmetrically slidably connected to the inside of the first box body 53, and the first movable seats 532 provide a mounting carrier for the first clamping plate 533, and the two first clamping plates 533 arranged opposite to each other are respectively mounted on the front ends of the two first movable seats 532. The two first clamping plates 533 are used together to clamp the electric pole; The two guide wheels 531 connected to the rope 3 and attached to the lower end of the second box body 54 are symmetrically rotated and connected to the upper end of the first box body 53. The two guide wheels 531 are used in combination to guide the movement of the rope 3, and the output shaft of the third driving device whose fixed part is installed at the bottom end of the box body 1 is connected to the winding wheel 31 located in the box body 1. The winding wheel 31 is driven to rotate through the third driving device. The third driving device can use the first motor 32, and then the rope 3 whose head end passes through the box body 1 and is connected to the front end of the box body 1 and is located on the upper side of the multi-section telescopic rod 4 is wound around the winding wheel 31. The winding wheel 31 is used in combination with the rope 3 to move the box body 1; The second box body 54 arranged in a transverse manner is arranged on the lower end of the mounting plate 5, and a mounting carrier is provided for the second box body 54 and other components through the mounting plate 5, and a second bidirectional screw 545 that penetrates through the two second movable seats 544 and is threadedly connected to the two second movable seats 544 is rotatably connected to the inside of the second box body 54, and the two second movable seats 544 are moved relative to each other through the second bidirectional screw 545, and then the output shaft of the fourth driving device whose fixed part is installed at the right end of the second box body 54 is connected to the second bidirectional screw 545, and the second bidirectional screw 545 is driven to rotate through the fourth driving device, and the fourth driving device can use a fourth motor 541; Two second movable seats 544 extending from the front side of the second box body 54 are symmetrically slidably connected to the inside of the second box body 54, and the second movable seats 544 are used to provide a mounting carrier for the second clamping plate 542, and the two second clamping plates 542 arranged opposite to each other are respectively mounted on the front ends of the two second movable seats 544, and the second clamping plates 542 are used to provide a mounting carrier for the rolling member, and the fixing parts of multiple rolling members are evenly installed at the inner ends of the two second clamping plates 542. The multiple rolling members are used in combination to make the second clamping plate 542 rollingly connected to the outer end of the pole, and the rolling member can be a bull's eye 543; A plurality of arms 2, the other ends of which are movably mounted on the upper end of the box body 1 and located on the upper side of the rope 3 and on the rear side of the second box body 54 and are arranged obliquely with the front higher and the rear lower, are equidistantly and movably mounted on the lower end of the mounting plate 5. The plurality of arms 2 are used in combination to lift the mounting plate 5, and the fixed parts of the two first movable members are symmetrically arranged on the lower end of the first box body 53. The two first movable members are used in combination to move the first box body 53. The first movable member can adopt a second universal wheel 534, and the fixed parts of the four second movable members are respectively mounted on the four corner positions of the lower end of the box body 1. The four second movable members are used in combination to move the box body 1. The second movable member can adopt a first universal wheel 12.

[0019] When in use, the box body 1 is first pushed, and with the cooperation of the two second universal wheels 534 and the four first universal wheels 12, the structure formed by the box body 1, the first box body 53 and the multiple multi-section telescopic rods 4 and other components is moved, and then the structure is moved and moved near the pole. At this time, the two first clamping plates 533, the two second clamping plates 542 and the two functional boards 52 are respectively located on both sides of the pole; Then, the third motor 535 is started to drive the first bidirectional screw 536 to rotate. Since the first bidirectional screw 536 is threadedly connected to the two first movable seats 532, the rotation of the first bidirectional screw 536 causes the two first movable seats 532 to move inward, thereby causing the two first clamping plates 533 to move inward, so that the two first clamping plates 533 clamp the pole, thereby fastening the first box body 53 to the pole. Then, the fourth motor 541 is started to drive the second bidirectional screw 545 to rotate. Since the second bidirectional screw 545 is threadedly connected with the two second movable seats 544, the rotation of the second bidirectional screw 545 will cause the two second movable seats 544 to move inward, thereby causing the two second clamping plates 542 to move inward, thereby causing the bull's eyeballs 543 to move inward, and then causing the rolling parts of the multiple bull's eyeballs 543 to contact the outer end of the pole, so that the pole and the second box body 54 are movably installed; Then the high-altitude power cable maintenance personnel move to the installation plate 5, and then start the first motor 32, thereby driving the winding wheel 31 to rotate, so as to wind up the rope 3, and with the assistance of the two guide wheels 531, the box body 1 moves toward the first box body 53, so that the lower parts of the multiple supporting arms 2 move with the movement of the box body 1, so that the upper parts of the multiple supporting arms 2 move upward, and then the installation plate 5 moves upward to a suitable position; During the upward movement of the mounting plate 5, the assembly formed by the two second clamping plates 542 moves upward along the pole with the assistance of the multiple bull's eyeballs 543, which can guide the movement of the mounting plate 5, so that the maintenance personnel of the high-altitude power cables can perform mechanical lifting movement, effectively reduce the labor intensity, effectively reduce the probability of falling, have good safety, and effectively ensure the maintenance effect of the high-altitude power cables; After the maintenance is completed, the first motor 32 is used to rotate the winding wheel 31 in the opposite direction, so that the rope 3 wound on the winding wheel 31 is released. At this time, under the weight of the high-altitude power cable maintenance personnel themselves and the weight of the platform structure formed by the mounting plate 5, movable plate 6 and other components, the platform structure moves down along the pole, and with the assistance of multiple arms 2, the box body 1 moves outward, thereby lowering the platform structure back to its original position.

[0020] Embodiment 2: A first motor 32, a winding wheel 31, a rope 3 and two guide wheels 531 are used to move the box body 1 toward the first box body 53, and the mounting plate 5 is moved upward with the assistance of multiple arms 2, so that the high-altitude power cable maintenance personnel can perform mechanical lifting movement. After the lifting, the high-altitude power cable maintenance personnel are located on one side of the pole, but there are multiple power cables installed on the top of the pole, which makes it easy for the high-altitude power cable maintenance personnel to be unable to effectively perform maintenance work on the power cables on the other side of the pole, causing the high-altitude power cable maintenance personnel to descend to change the position of the lifting device, resulting in difficulty in the maintenance of power cables in different directions of the pole, high labor intensity and many lifting times.

[0021] In order to solve the above problems, Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.16 As shown, two relatively arranged function boards 52 with arc-shaped cross sections and upper end surfaces overlapping with the upper end surface of the mounting plate 5 are respectively mounted on the left and right ends of the mounting plate 5 with a trapezoidal cross section that is narrow in front and wide in the back. The mounting plate 5 is used in conjunction with the two function boards 52 to provide a mounting carrier for the arc box 7, and the arc box 7 with the lower end connected to the two function boards 52 is arranged on the upper end of the mounting plate 5, and the arc box 7 is used to provide a mounting space for components such as the arc gear 71; The arc gear 71 is installed on the bottom end of the arc box 7. The arc gear 71 provides a route for the rotation gear 64 to move. The rotation gear 64 in the arc box 7 is meshed with the rear end of the arc gear 71. The rotation gear 64 and the arc gear 71 are used together to move the movable plate 6. The upper end surface of the arc box 7 is recessed downward to form an arc groove 72 that is connected to the inner cavity of the arc box 7. Through the arc groove 72, on the one hand, the output shaft of the first driving device is effectively connected to the rotation gear 64, and on the other hand, the normal movement of the rotation gear 64 in the arc box 7 is effectively guaranteed. Two first rods 63 located at the rear side of the arc groove 72 and both slidably connected to the upper end of the arc box 7 are symmetrically arranged on the lower end of the movable plate 6 located on the upper side of the arc box 7. The two first rods 63 are used in combination to make the arc box 7 and the movable plate 6 movably connected. Two second rods 65 located inside the arc box 7 and both slidably connected to the upper end of the mounting plate 5 are symmetrically installed on the lower end of the movable plate 6. The two first rods 63 and the two second rods 65 are used in combination to lift the movable plate 6. Then, the guardrail 61 is installed on the upper end of the movable plate 6. Through the guardrail 61, a safe operating space is formed at the upper end of the movable plate 6. The output shaft of the first driving device whose fixed part is installed on the upper end of the movable plate 6 and located at the rear side of the guardrail 61 passes through the movable plate 6 and the arc groove 72 and is connected to the rotating gear 64. The rotating gear 64 is driven to rotate through the first driving device. The first driving device can use a second motor 62, and two ladders 51 located on the left and right sides of the box body 1 are symmetrically installed on the rear end of the mounting plate 5. The two ladders 51 are used in combination, which can enable maintenance personnel to climb onto the mounting plate 5 on the one hand, and lift the mounting plate 5 on the other hand.

[0022] When in use, the structure formed by the box body 1, the first box body 53 and the multiple multi-section telescopic rods 4 is first moved to the vicinity of the pole, and the first box body 53 is fastened to the pole by using the third motor 535, the first bidirectional screw 536, the two first movable seats 532 and the two first clamping plates 533, and then the rolling parts of the multiple bull's eye balls 543 are brought into contact with the outer end of the pole by using the fourth motor 541, the second bidirectional screw 545, the two second movable seats 544, the two second movable seats 544 and the two second clamping plates 542, so that the pole and the second box body 54 are movably installed; Then the high-altitude power cable maintenance personnel climbs onto the installation plate 5 through the ladder 51, and then opens the door on the guardrail 61, and then enters the safe operation space formed by the movable plate 6 and the guardrail 61, and then closes the door on the guardrail 61, and then uses the first motor 32, the winding wheel 31, the rope 3 and the two guide wheels 531 to move the box body 1 toward the first box body 53, and with the assistance of the multiple supporting arms 2, the installation plate 5 is moved upward to a suitable position, so that the high-altitude power cable maintenance personnel can perform a mechanical lifting movement; When the high-altitude power cable maintenance personnel rise to a suitable height, the high-altitude power cable maintenance personnel will perform maintenance operations on the power cables installed on the top of the pole and facing the high-altitude power cable maintenance personnel. When the maintenance is completed, the second motor 62 is started to rotate the rotating gear 64. Because the rotating gear 64 is meshed with the arc gear 71, the rotating gear 64 rotates and simultaneously moves along the arc gear 71, thereby causing the movable plate 6 to move around the pole, thereby causing the high-altitude power cable maintenance personnel to move to the other direction of the pole, so that the high-altitude power cable maintenance personnel can conveniently maintain the power cables installed in different directions of the pole, effectively reducing labor intensity, reducing the number of lifts, and effectively ensuring the maintenance effect of the high-altitude power cables.

[0023] Embodiment three: A first motor 32, a winding wheel 31, a rope 3 and two guide wheels 531 are used to move the box body 1 toward the first box body 53, and the mounting plate 5 is moved upward with the assistance of multiple arms 2, so that the high-altitude power cable maintenance personnel can perform mechanical lifting movements. However, after the lifting, due to the weight of the high-altitude power cable maintenance personnel themselves and the weight of the mounting plate 5 and other components themselves, the mounting plate 5 and other components are prone to move downward, and exert downward pressure on the arm 2, resulting in a high probability of the box body 1 moving back and other movements, which will affect the maintenance effect of the high-altitude power cable.

[0024] In order to solve the above problems, Figure 1 , Figure 3 , Fig.11 and Fig.12 As shown, the lower end surface of the box body 1 is recessed upward to form a through slot 14 that is connected to the inner cavity of the box body 1 and is located at the rear side of the winding wheel 31 and the first motor 32. Through the through slot 14, the rectangular block 132 is moved from the box body 1 to the lower side of the box body 1, and the rectangular block 132 is installed on the middle part of the lower end of the moving plate 131 located in the box body 1. The moving plate 131 is used to provide a mounting carrier for the rectangular block 132, and an anti-skid pad 133 located just above the through slot 14 is installed on the lower end of the rectangular block 132. Through the anti-skid pad 133, the rectangular block 132 is restricted and installed between the rectangular block 132 and the ground; The movable part of the lifting device located at the rear side of the support arm 2 and the fixed part installed on the upper end of the box body 1 is passed through the box body 1 and connected to the moving plate 131. The moving plate 131 is driven to move up and down in the box body 1 through the lifting device. The lifting device can use an electric push rod 13, and a round rod 11 located on the right side of the lifting device and extending from the upper side of the box body 1 and slidably connected to the box body 1 is installed on the upper end of the moving plate 131. The movement of the moving plate 131 is guided by the round rod 11.

[0025] When in use, the structure formed by the box body 1, the first box body 53 and the multiple multi-section telescopic rods 4 is first moved to the vicinity of the electric pole, and the first box body 53 is fastened and installed with the electric pole by using the third motor 535, the first bidirectional screw 536, the two first movable seats 532 and the two first clamping plates 533, and then the electric pole and the second box body 54 are movably installed by using the fourth motor 541, the second bidirectional screw 545, the two second movable seats 544, the two second movable seats 544, the two second clamping plates 542 and the multiple bull's eye balls 543; Then the high-altitude power cable maintenance personnel enter the safe operating space formed by the movable plate 6 and the guardrail 61, and then use the first motor 32, the winding wheel 31, the rope 3 and the two guide wheels 531 to move the box body 1 toward the first box body 53, and with the assistance of the multiple supporting arms 2, the mounting plate 5 moves upward to a suitable position, so that the high-altitude power cable maintenance personnel can perform mechanical lifting movement; When the high-altitude power cable maintenance personnel rise to a suitable height, they start the electric push rod 13, which in turn moves the movable plate 131 downward, so that the rectangular block 132 moves downward and passes through the through slot 14, so that the anti-slip pad 133 installed at the lower end of the rectangular block 132 is in squeeze contact with the ground, thereby achieving a restricted installation between the box body 1 and the ground, effectively reducing the probability of movement such as the box body 1 moving back, and effectively ensuring the high-altitude power cable maintenance effect.

[0026] Embodiment 4: A first motor 32, a winding wheel 31, a rope 3 and two guide wheels 531 are used to move the box body 1 toward the first box body 53, and the mounting plate 5 is moved upward with the assistance of multiple arms 2, so that the high-altitude power cable maintenance personnel can perform mechanical lifting movement, and the anti-skid pad 133 is used to squeeze the ground to prevent the box body 1 from moving back and other movements, and the arc box 7, arc gear 71, rotating gear 64 and other components are used to enable the high-altitude power cable maintenance personnel to change the maintenance direction. However, after the maintenance direction is changed, it is easy to apply eccentric downward pressure to the mounting plate 5, multiple arms 2 and the box body 1, resulting in a high probability of the box body 1 tilting, causing partial separation between the anti-skid pad 133 and the ground, resulting in a high probability of the box body 1 moving back and other movements again, which will affect the maintenance effect of the high-altitude power cable.

[0027] In order to solve the above problems, Fig.11 , Fig.13 , Fig.14 , Fig.15 and Fig.16As shown, a plurality of U-shaped frames 143 are respectively installed on the four vertical inner walls of the through slot 14, and a mounting carrier is provided for the rotating shaft 144 and other components through the U-shaped frames 143, and round boxes 142 are installed at the outer ends of the two transverse parts of the U-shaped frames 143, and a mounting space is provided for the coil spring 145 through the round boxes 142, and then a rotating shaft 144 that penetrates the U-shaped frames 143 and the two round boxes 142 and is rotatably connected to the round boxes 142 is rotatably connected between the two transverse parts of the U-shaped frames 143, and a mounting carrier is provided for the hook 141 through the rotating shaft 144; Two coil springs 145 located in the round box 142 and with their outer ends mounted on the inner wall of the round box 142 are symmetrically mounted on the outer end of the rotating shaft 144. The two coil springs 145 are used together to rotate the rotating shaft 144 back to its original position, and a hook 141 located in the through slot 14, extending into the box body 1, located on the lower side of the rectangular block 132 and between the two horizontal parts of the U-shaped frame 143 is installed on the outer end of the rotating shaft 144. Through the hook 141, the box body 1 is installed with multi-directional restrictions on the ground.

[0028] After the high-altitude power cable maintenance personnel are lifted up, the electric push rod 13 is used to move the moving plate 131, the rectangular block 132 and the anti-skid pad 133 downward, and the anti-skid pad 133 is squeezed into contact with the ground to achieve the restricted installation between the box body 1 and the ground. During the downward movement of the rectangular block 132, the rectangular block 132 first contacts the upper ends of the arc-shaped parts of the plurality of hook claws 141, and then the rectangular block 132 continues to move downward, thereby causing the plurality of hook claws 141 to rotate downward around the corresponding rotating shafts 144, so that the plurality of hook claws 141 are synchronously inserted into the ground, and the box body 1 and the ground are installed in a multi-directional restricted manner, which effectively reduces the probability of tilting of the assembly formed by the box body 1, the mounting plate 5 and other components, and effectively reduces the probability of the box body 1 moving back again, so as to effectively ensure the maintenance effect of the high-altitude power cable; When the hook 141 rotates downward, the shaft 144 will rotate, and then the corresponding two coil springs 145 will contract simultaneously, so that the two coil springs 145 will generate elastic force. When the high-altitude power cable maintenance personnel complete the maintenance and descend, the electric push rod 13 is used to return the moving plate 131, the rectangular block 132 and the anti-slip pad 133 to the box body 1. Under the action of the elastic force of the two coil springs 145, the corresponding shaft 144 and the hook 141 will rotate back to their original positions, thereby releasing the restriction between the box body 1 and the ground.

[0029] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
