This electric iron tower wire stringing device can effectively ensure that the cable will not fall off from the pulley at a high speed due to accidental detachment.

Description

Technical Field

[0001] The invention relates to the technical field of power iron tower wiring, in particular to a power iron tower wiring device. Background Art

[0002] In the construction of modern power transmission lines, the construction of overhead lines is a key step, among which the line construction is particularly important. The main task of the line-laying device is to safely and effectively install the transmission wires and lightning conductors weighing tons on high towers, so as to ensure the safety and efficiency of power transmission. The line-laying pulley will be used in the line-laying operation of the power tower. The line-laying pulley is a pulley used to lay out the corresponding wires during tension line laying. The line-laying pulley can be divided into conductor line-laying pulleys, ground wire line-laying pulleys, optical fiber composite overhead ground wire line-laying pulleys, etc. according to the type of wires.

[0003] However, when actually using a cable-laying pulley for overhead line-laying operations, the cable may accidentally fall off the pulley and fall rapidly. Once one end of the traction cable accidentally falls off and causes the cable to fall rapidly, a serious safety accident may occur. The existing ordinary cable-laying pulley does not have the function of emergency limit braking, and cannot slow down or even lock the fall of the cable in time. The cable may fall and hit the working equipment or personnel, which reduces the safety of the user when using the cable-laying pulley to lay the cable, and is prone to safety accidents. To this end, we propose a power tower cable-laying device.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a transmission unit, which can effectively ensure that the cable will not fall off from the pulley at a high speed due to accidental detachment when the user uses the line-laying pulley to install high-altitude cables on power towers. Once one end of the traction cable accidentally falls off, causing the cable to fall at a high speed, a serious safety accident may occur. The transmission unit can be used to avoid this situation in a timely and rapid manner, and will not affect the normal transmission and traction of the cable. However, when the cable falls from the pulley at a high speed, the one-way gear can drive the transmission gear to make the fixed wheel fall quickly to limit the cable, which can timely and effectively slow down the falling of the cable, and slow down the falling speed through the friction force on the surface of the cable, which can avoid the situation where the cable falls and hits the working equipment or personnel, thereby increasing the safety of users when using the line-laying pulley to install cables to a certain extent and avoiding safety accidents.

[0021] The present invention sets a reinforcing unit. When the transmission unit controls the falling speed of the cable for the first time, the surface of the high-friction rubber pad is tightly attached to the surface of the cable through the inclined plate. The surface skin of the cable is generally made of rubber material. The friction force when in contact with the high-friction rubber pad is further increased. In addition, the setting direction of the inclined plate and the high-friction rubber pad is opposite to the falling direction of the cable. Therefore, the friction effect can be further enhanced by utilizing the gravity speed of the falling cable and the inclined plate and the high-friction rubber pad set in the opposite direction so that the braking effect can be quickly achieved. At the same time, the fixed wheel and the inclined plate press down the cable to press it on the pulley to form a concave shape, which further increases the effect of emergency limit braking.

[0022] The present invention provides an auxiliary mechanism, and the traction end of the cable is prone to falling off when there are two or three cables being pulled together. This operation is generally carried out by connecting the cable to the traction rope through a walking plate. When the walking plate is pulled onto the pulley surface of the pulley, because the walking plate is rectangular, the effect of pulling on the circular pulley may not be very obvious. Because the walking plate is pulled from bottom to top, when the angle between it and the pulley is too large, it may get stuck. Through the setting of the auxiliary mechanism, when the walking plate contacts the pulley and the baffle bar, the sliding wheel is driven by the pulling of the second steel cable to lift the walking plate from the bottom of the walking plate, so that the angle between the walking plate and the pulley becomes flat. At this time, the walking plate can pass through the pulley more smoothly, thereby reducing the situation of accidental cable falling off at the root to a certain extent, and further increasing the safety of cable erection operations on power towers.

[0037] As a further limitation of the safety brake mechanism 2 of the present invention, the transmission unit 21 includes a fixed plate 2101, which is fixedly connected to one side of the bracket 1. There are two fixed plates 2101. A one-way gear 2102 is arranged on the surface of the fixed plate 2101. The outer ring and the inner ring of the one-way gear 2102 are in contact with one side of the fixed plate 2101. There are four one-way gears 2102. One end of the transmission shaft 7 passes through one side of the fixed plate 2101. The inner ring of the one-way gear 2102 is in contact with one end of the transmission shaft 7. The fixed plate 2101 is rotatably connected to the surface of the fixed plate 2101 with a transmission gear 2103, which meshes with the outer ring of the one-way gear 2102. The fixed plate 2101 is fixedly connected to the surface of the fixed frame 2104, and the surface of the fixed frame 2104 is fixedly connected to the shell 2105, which is rotatably connected to one side of the transmission gear 2103. The inner wall of the shell 2105 is rotatably connected to a winding roller 2106, and one end of the winding roller 2106 penetrates the surface of the shell 2105 and meshes with the transmission gear 210 3, the surface of the winding roller 2106 is fixedly connected with a first steel cable 2107, both sides of the bracket 1 are fixedly connected with positioning plates 2108, the bottom of the positioning plate 2108 is provided with a fixing rod 2109, one end of the first steel cable 2107 is fixedly connected to the surface of the fixing rod 2109, the inner wall of the bracket 1 is slidably connected with a fixing block 2114, the fixing rod 2109 is fixedly connected to the surface of the fixing block 2114, the bottom of the positioning plate 2108 is fixedly connected with a tension spring 2110, One end is fixedly connected to the surface of the fixed rod 2109, and both sides of the bracket 1 are fixedly connected with a mounting plate 2111, and the surface of the mounting plate 2111 is fixedly connected with a sliding rod 2112, and one end of the sliding rod 2112 is fixedly connected to the bottom of the positioning plate 2108, and the surface of the sliding rod 2112 is slidingly sleeved with a sliding sleeve 2113, and the surface of the sliding sleeve 2113 is fixedly connected to the surface of the fixed block 2114, and both sides of the bracket 1 are fixedly connected with a buckle 2115, and the inner wall of the buckle 2115 is in contact with the surface of the first steel cable 2107.

[0038] The specific implementation method of this embodiment is as follows: when the user uses the cable-laying pulley to install the high-altitude cable on the power tower, it can effectively ensure that the cable will not fall off the pulley at a high speed due to accidental detachment. Once one end of the traction cable falls off accidentally, causing the cable to fall at a high speed, a serious safety accident may occur. By setting up the transmission unit 21, this situation can be avoided in time and quickly. When the cable is normally transported and pulled, it will not drive the one-way gear 2102 to rotate. However, when the cable falls from the pulley at a high speed, the friction between the falling cable and the pulley 8 will drive the pulley 8 and the transmission shaft 7 to rotate in the opposite direction due to its own gravity, thereby driving the one-way gear 2102 to rotate under force, and regardless of whether the traction cable is normally transported Or the cable falls, the pulley 8 is always in contact with the surface of the cable, and the one-way gear 2102 here is a prior art, and its structural principle is to achieve one-way transmission of torque and prevention of reverse transmission through the special tooth design, ensuring that the one-way gear 2102 is smoothly meshed and rotated in one direction, while in the opposite direction, due to the inclined surface of the tooth shape, the one-way gear 2102 cannot rotate reversely, and at the same time, the transmission gear 2103 is meshed with the one-way gear 2102, and the one-way gear 2102 is rotated under force, which will drive the transmission gear 2103 to rotate, and the one-way gear 2102 on the same side is rotated in the same force direction. At this time, the winding roller 2106 in the shell 2105 quickly winds up the first steel cable 2107 On its surface, the first steel cables 2107 on both sides are wound up at the same time to drive the fixing rod 2109 to move downward. By setting the fixing frame 2104, the shell 2105 can be fixed so that it will not fall off accidentally, which increases the stability during use. The fixing rod 2109 moves downward to drive the fixing block 2114 and the fixing wheel 2202 to drop rapidly, so that the surface of the fixing wheel 2202 contacts the surface of the cable, and the fixing wheel 2202 is pressed downward so that the cable can be pressed on the pulley pulley 8 to form a concave shape, which further increases the effect of the emergency limit brake. By setting the sliding rod 2112 and the sliding sleeve 2113, the falling of the fixing block 2114 and the fixing wheel 2202 can be guided, so that The up and down movement can be smoother and more fluent. By setting the mounting plate 2111, the position of the slide bar 2112 can be fixed to make it more stable. The first steel cable 2107 slides in the buckle 2115, and the buckle 2115 also guides the first steel cable 2107 to a certain extent. When the traction end of the cable is repaired and the cable can be pulled smoothly, the one-way gear 2102 loses the force, and the fixed wheel 2202 also loses the downward pressure. At this time, the tension spring 2110 stretched by the fixed block 2114 contracts, which can drive the fixed rod 2109 and the fixed wheel 2202 to move up and reset. By setting the positioning plate 2108, the position of the tension spring 2110 can be fixed to make it more stable when in use.

[0039] Example 2: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a power tower line device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0040] As a further limitation of the safety braking mechanism 2 of the present invention, the reinforcing unit 22 includes a lower pressure plate 2201, which is arranged at the top of the bracket 1, and the bottom of the lower pressure plate 2201 is fixedly connected with a fixed wheel 2202, and the two ends of the fixed wheel 2202 are respectively fixedly connected to the surface of the fixed block 2114. By setting the lower pressure plate 2201, the positions of the fixed wheel 2202 and the fixed block 2114 can be fixed, and at the same time, they can move up and down together.

[0041] The bottom of the lower pressure plate 2201 is fixedly connected with a sleeve block 2203, and the number of the sleeve blocks 2203 is six. The inner walls of the sleeve blocks 2203 are slidably connected with pressure blocks 2204. By arranging the sleeve blocks 2203 and the pressure blocks 2204, when the fixed wheel 2202 presses down and contacts the surface of the cable, the inclined plate 2208 and the high-friction rubber pad 2209 successively contact the surface of the cable, and the retraction of the pressure block 2204 in the sleeve block 2203 can cooperate with the fixed wheel 2202 to better press the cable into a concave shape, thereby further increasing the limiting effect.

[0042] The inner wall of the sleeve block 2203 is fixedly connected with a spring 2205, and the number of the springs 2205 is several. One end of the spring 2205 is fixedly connected to the top of the pressing block 2204. By setting the spring 2205, the pressing block 2204 can be pressed at different positions, so that it can better press the cable into a concave shape. At the same time, the spring 2205 can also play a role in resetting the pressing block 2204.

[0043] The inner wall of the pressing block 2204 is rotatably connected to a rotating shaft 2206, and the inner wall of the pressing block 2204 is fixedly connected to a torsion spring 2207. The torsion spring 2207 is used in conjunction with the rotating shaft 2206. By setting the rotating shaft 2206 and the torsion spring 2207, the rotating shaft 2206 can allow the inclined plate 2208 and the high-friction rubber pad 2209 to produce a certain inclination after moving down to contact the cable surface, allowing the high-friction rubber pad 2209 to contact the cable surface over a larger area. At the same time, the torsion spring 2207 can also play a role in resetting the inclined plate 2208 and the high-friction rubber pad 2209.

[0044] The surface of the rotating shaft 2206 is fixedly connected with an inclined plate 2208, and the number of the inclined plates 2208 is several. The surface of the inclined plates 2208 is fixedly connected with a high-friction rubber pad 2209. The setting direction of the inclined plate 2208 and the high-friction rubber pad 2209 is opposite to the falling direction of the cable. Therefore, by utilizing the gravity speed of the falling cable and the inclined plates 2208 and the high-friction rubber pads 2209 set in the opposite direction, the friction effect can be further enhanced so that the braking effect can be achieved quickly.

[0045] The specific implementation of this embodiment is as follows: by setting the lower pressing plate 2201, the positions of the fixing wheel 2202 and the fixing block 2114 can be fixed, and at the same time, they can move up and down together; by setting the sleeve block 2203 and the pressing block 2204, the sleeve block 2203 and the pressing block 2204 are matching rectangular parts; the pressing block 2204 slides on the inner wall of the sleeve block 2203; when the fixing wheel 2202 is pressed down to contact the cable surface, the inclined plate 2208 and the high-friction rubber pad 2209 successively contact the cable surface; the retraction of the pressing block 2204 in the sleeve block 2203 can cooperate with the fixing wheel 2202 to better press the cable into a concave shape, further increasing the limiting effect; by setting the spring 2205, the pressing of the pressing block 2204 at different positions can be realized, so that it can be more The cable is pressed into a concave shape, and the spring 2205 can also play a role in resetting the pressing block 2204. By setting the rotating shaft 2206 and the torsion spring 2207, the rotating shaft 2206 can make the inclined plate 2208 and the high friction rubber pad 2209 produce a certain inclination after moving down to contact the cable surface, so that the high friction rubber pad 2209 can contact the cable surface with a larger area. At the same time, the torsion spring 2207 can also play a role in resetting the inclined plate 2208 and the high friction rubber pad 2209. The setting direction of the inclined plate 2208 and the high friction rubber pad 2209 is opposite to the direction of cable falling. Therefore, the gravity speed of the falling cable and the inclined plate 2208 and the high friction rubber pad 2209 set in the opposite direction can further enhance the friction effect so that it can quickly achieve the braking effect.

[0046] Example 3: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a power tower line device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0047] As a further limitation of the auxiliary mechanism 3 of the present invention, the auxiliary mechanism 3 includes a first sliding plate 301, the first sliding plate 301 is fixedly connected to the inner wall of the bracket 1, the number of the first sliding plates 301 is two, a first sliding groove 302 is opened on the surface of the first sliding plate 301, a first through hole 303 is opened on the surface of the first sliding plate 301, the first through hole 303 penetrates to the inner wall of the first sliding groove 302, the inner wall of the first sliding groove 302 is slidably connected with a first sliding rod 304, both ends of the first sliding rod 304 are fixedly connected with a first protective block 305, the surface of the first protective block 305 contacts the surface of the first sliding plate 301, and the surface of the first sliding rod 304 is fixedly connected with a blocking rod 313, There are two blocking rods 313. By setting the first sliding plate 301, the first sliding rod 304 can slide in a straight line on the inner wall of the first sliding groove 302. At the same time, the first protective block 305 can protect and limit the first sliding rod 304 to prevent it from falling off from the inner wall of the first sliding groove 302, thereby increasing stability. When the walking plate contacts the pulley 8 and the blocking rod 313, the sliding wheel 310 is driven by the pulling of the second steel cable 312 to lift the walking plate from the bottom of the walking plate, so that the angle between the walking plate and the pulley 8 becomes flat. At this time, the walking plate can pass through the pulley more smoothly, thereby reducing the accidental falling of the cable to a certain extent at the root, and further increasing the safety of the cable erection operation of the power tower.

[0048] The surface of the fixed plate 2101 is fixedly connected with an arc plate 306, and a second sliding groove 307 is opened on the surface of the arc plate 306. A second through hole 308 is opened on the surface of the arc plate 306, and the second through hole 308 penetrates to the inner wall of the second sliding groove 307. By setting the arc plate 306, the second sliding rod 309 can move in a circular arc shape on the inner wall of the second sliding groove 307, which facilitates the sliding wheel 310 to better support the bottom end of the walking plate.

[0049] The inner wall of the second sliding groove 307 is slidably connected to a second sliding rod 309, the surface of the second sliding rod 309 is rotatably connected to a sliding wheel 310, the number of sliding wheels 310 is three, both ends of the second sliding rod 309 are fixedly connected to second protection blocks 311, the surface of the second protection block 311 contacts the surface of the arc plate 306, the surface of the second sliding rod 309 is fixedly connected to a second steel cable 312, the number of second steel cables 312 is two, and the other end of the second steel cable 312 is fixedly connected to the first The surface of the first sliding rod 304, the surface of the second steel cable 312 is in contact with the inner wall of the first through hole 303 and the second through hole 308. By setting the first through hole 303 and the second through hole 308, the second steel cable 312 can slide in the first through hole 303 and the second through hole 308. At the same time, the first through hole 303 and the second through hole 308 also guide the sliding of the second steel cable 312. The walking plate contacts the pulley 8 and the blocking rod 313, and the blocking rod 313 drives the first sliding rod 304 to slide in the first sliding plate. The inner wall of the groove 302 slides in a straight line, and at the same time, the first sliding rod 304 drives the second sliding rod 309 to move in an arc shape on the inner wall of the second sliding groove 307 through the second steel cable 312. The sliding wheel 310 arranged on the surface of the second sliding rod 309 contacts the bottom end of the walking plate to lift it up, so that the angle between the walking plate and the pulley 8 becomes flat, and the walking plate can pass the pulley more smoothly at this time. At the same time, the setting of the second protection block 311 can protect and limit the second sliding rod 309, preventing it from falling from the second The inner wall of the sliding groove 307 falls off, which increases stability. Because the first sliding plate 301 is set to have a certain inclination, when the walking plate pushes the blocking rod 313 to the other end, the bottom of the blocking rod 313 will slide to the upper surface of the walking plate, and will not hinder the movement of the walking plate. At this time, relying on the gravity of the second sliding rod 309 and the sliding wheel 310 themselves, it can slide down along the inner wall of the second sliding groove 307, and then the first sliding rod 304 and the blocking rod 313 can be driven to reset through the second steel cable 312.

[0050] The specific implementation of this embodiment is as follows: when pulling the cable to string the line, the pulling direction is to extend forward from the side close to the first sliding plate 301. By setting the first sliding plate 301, the first sliding rod 304 can slide linearly on the inner wall of the first sliding groove 302. At the same time, the first protective block 305 can protect the first sliding rod 304 and prevent it from falling off from the inner wall of the first sliding groove 302, thereby increasing stability. In the cable laying operation, it is sometimes necessary to pull two or three cables by a pulling line for stringing. At this time, a cable running board will be used. The cable running board is an important auxiliary equipment used in power construction and telecommunication line construction. Its functions include preventing twisting and flipping, ensuring pulling and The walking board is a prior art. When the walking board contacts the pulley 8 and the blocking rod 313, the sliding wheel 310 is driven by the pulling of the second steel cable 312 to lift the walking board from the bottom of the walking board, so that the angle between the walking board and the pulley 8 becomes flat. At this time, the walking board can pass through the pulley more smoothly, thereby reducing the accidental falling of the cable to a certain extent at the root, and further increasing the safety of the cable erection operation of the power tower. By setting the arc plate 306, the second sliding rod 309 can move in an arc shape on the inner wall of the second sliding groove 307, which is convenient for the sliding wheel 310 to better lift the bottom end of the walking board. By setting the first through hole 303 and the second through hole 308, The second steel cable 312 can slide in the first through hole 303 and the second through hole 308. At the same time, the first through hole 303 and the second through hole 308 also guide the sliding of the second steel cable 312. The walking plate contacts the pulley 8 and the blocking rod 313. The first sliding rod 304 is a square rod. The blocking rod 313 drives the first sliding rod 304 to slide in a straight line on the inner wall of the first sliding groove 302. At the same time, the first sliding rod 304 drives the second sliding rod 309 to move in an arc shape on the inner wall of the second sliding groove 307 through the second steel cable 312. The sliding wheel 310 arranged on the surface of the second sliding rod 309 contacts the bottom end of the walking plate to lift it up, so that the angle between the walking plate and the pulley 8 is reduced. At this time, the walking plate 309 and the sliding wheel 310 can rely on their own gravity to slide down along the inner wall of the second sliding groove 307, and then the first sliding rod 304 and the blocking rod 313 can be driven to reset through the second steel cable 312.
