Description

Technical Field

[0001] This invention relates to the field of power tower equipment technology, and in particular to a power tower with a lifting mechanism. Background Technology

[0002] In recent years, with the rapid economic growth, my country's power industry has developed rapidly, which has promoted the development of the transmission line tower industry. Power towers are widely used in the power grid, and the installation and maintenance of high-voltage transmission line equipment often require construction workers to climb the towers.

[0003] Chinese Patent Publication No. CN212799197U discloses an automatic lifting device for power transmission towers, including a base, a vertical pole fixedly connected to the upper surface of the base, a top plate fixedly connected to the top of the vertical pole, a first cable drum fixedly connected to the upper surface of the top plate via a bracket, and a lifting motor fixedly connected to the upper surface of the top plate. The device uses a lifting motor to move the car up and down along the upright. Once the desired height is reached, the forward and reverse motors start, rotating the second reel to release the pull rope. The overlapping plate rotates clockwise around the round rod, making the overlapping plate overlap with the power tower. Then, the electric push rod retracts, moving the round rod and the overlapping plate to the left, so that the anti-slip strip contacts the power tower, preventing the overlapping plate from accidentally sliding or falling off the power tower. This further increases the stability of the overlapping plate when it overlaps with the power tower, enhancing the safety of the device. However, in actual use, most existing lifting devices have a fixed or semi-fixed connection with the tower body. Installation and dismantling require a lot of manpower and time. Moreover, different models of towers have different structural dimensions. One lifting device can usually only be adapted to a single model of tower and cannot be used interchangeably with multiple power towers of different specifications. This results in maintenance units needing to equip themselves with multiple lifting devices adapted to different towers, significantly increasing equipment procurement and storage costs. Summary of the Invention

[0004] The main objective of this invention is to provide a power tower with a lifting mechanism, which can effectively solve the problems of existing lifting devices being fixedly or semi-fixedly connected to the tower body, requiring a lot of manpower and time for installation and dismantling, and the structural dimensions of different tower models being different. A set of lifting devices can usually only be adapted to a single tower model and cannot be used interchangeably with multiple power towers of different specifications. This results in maintenance units needing to equip themselves with multiple sets of lifting devices adapted to different towers, which significantly increases the cost of equipment procurement and storage.

The outer surface of the installation chain is provided with multiple clamping mechanisms. A motor is provided on one side of the outer surface of the lower drive wheel set, and the motor is fixedly installed on the outer surface of the mounting shell. A transmission mechanism is provided on the other side of the outer surface of the two drive wheel sets. The multiple clamping mechanisms are adapted to be used with steel cables.

[0008] Preferably, the clamping mechanism includes a mounting frame, which is fixedly mounted on the outer surface of the mounting chain. Two jaws are symmetrically and rotatably mounted on one side of the inner surface of the mounting frame, and a connecting block is slidably mounted on the other side of the inner surface of the mounting frame. The outer surfaces of the connecting block are rotatably connected to the two jaws via connecting rods. Connecting handles are rotatably mounted on the outer surface of the mounting frame on both sides of the outer surfaces of the two jaws. A pull rod is slidably mounted on the inner wall of the mounting frame on the outer surface of the connecting block away from the jaws. A sliding handle is provided on the end face of the pull rod. Anti-slip strips are provided on the inner arc-shaped surfaces of the two jaws.

[0009] Preferably, the limiting component includes a fixing frame, which is fixedly installed on the inner surface of the mounting shell. The upper and lower inner walls of the fixing frame are rotatably connected to the middle of the outer surface of the two transmission wheel sets. Limiting mechanisms are provided on both sides of the inner cavity of the fixing frame. Positioning mechanisms are provided on both sides of the middle of the outer surface of the fixing frame. Both positioning mechanisms are fixedly installed on the inner surface of the fixing shell.

[0010] Preferably, the limiting mechanism includes a vertical slide rail, which is fixedly installed on the inner cavity surface of the fixed frame. Rotary slide rails are provided on both sides of the outer surface of the vertical slide rail, and a limiting member is provided between the two rotary slide rails. The limiting member is slidably installed on the inner cavity surface of the fixed frame.

[0011] Preferably, the limiting component includes a limiting slide, which is slidably mounted on the inner surface of the fixed frame. A plurality of springs are provided on one side of the outer surface of the limiting slide, and one end face of each of the plurality of springs is fixedly connected to the inner surface of the fixed frame.

[0012] Preferably, the vertical slide, the rotary slide, and the limiting slide are adapted to the slide handle.

[0013] Preferably, the positioning mechanism includes an L-shaped rod, which is fixedly installed on the lower part of the inner surface of the fixed shell. A limiting frame is provided on the upper part of the L-shaped rod, and a fixing plate is slidably installed in the middle of the inner cavity of the limiting frame. A plurality of springs are fixedly installed on the inner surface of the limiting frame on the end face of the fixing plate away from the L-shaped rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the lifting device uses the steel cable fixed to the top of the power tower as the load-bearing and guiding structure, eliminating the need for site support from aerial work platforms. It can be used flexibly on power towers in complex terrain areas such as mountains and hills. At the same time, the mounting frame adopts an openable structure with a fixed shell and a sliding mounting shell, which can quickly achieve assembly and separation from the steel cable, thus being compatible with various types of power towers and greatly improving the versatility of the device.

[0015] In this invention, the lifting device has a compact overall structure and is lightweight, allowing workers to carry it by hand. During installation, assembly can be completed simply by opening the mounting shell, inserting the steel cable, and locking the buckle. The disassembly process is similar, and a single disassembly and assembly operation can be completed in a short time. Furthermore, the device can be reused between different power towers, eliminating the need to equip different types of towers with dedicated lifting equipment, which significantly reduces the equipment procurement, transportation, and storage costs for operation and maintenance units.

[0016] In this invention, the linkage design of the lifting component and the limiting component enables precise control of the clamping and releasing actions of the clamping mechanism. Multiple clamping mechanisms are distributed at intervals along the installation chain. With the anti-slip strip on the inner arc surface of the claw, multi-point and stable clamping of the steel cable can be achieved, effectively avoiding slippage during the lifting process.

[0017] In this invention, a motor-driven transmission wheel set drives the installation chain in a cyclic transmission, realizing the automated lifting of the lifting device. Compared with the manual driving method, it greatly improves the lifting speed and work efficiency, while reducing the labor intensity of the workers. The coordinated design of the transmission mechanism and the installation chain ensures the smoothness of power transmission, avoids jamming during the lifting process, and improves the work comfort and experience of the workers.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1

[0022] like Figure 1 - Figure 15 As shown, this embodiment discloses a power tower with a lifting mechanism, including a power tower body 1. Two steel cables 2 are provided on the top of the power tower body 1. The lower parts of the two steel cables 2 are fixedly installed on the ground. Support handles 3 are provided on the lower parts of the two steel cables 2. Multiple hanging rings 31 are provided at the lower end of the support handles 3. Mounting frames 4 are provided on both sides of the outer surface of the support handles 3. Lifting components 5 are provided on both sides of the inner cavity of the two mounting frames 4. Limiting components 6 are provided in the middle of the two lifting components 5.

[0023] Specifically, the support handle 3, mounting frame 4, lifting component 5, and limiting component 6 together constitute the lifting device. When the staff performs power maintenance work on the power tower body 1, they can first open the mounting frame 4, then place the two steel cables 2 in the middle of the inner cavity of the mounting frame 4, and then lock and fix the two mounting frames 4. During this process, the lifting components 5 on both sides can clamp and position the two steel cables 2 respectively under the action of the limiting component 6. After that, the staff fixes the climbing rope in multiple hanging rings 31, and finally starts the lifting device, so that the lifting device can drive the staff to move upward along the steel cable 2 through the climbing rope.

[0024] Furthermore, after the maintenance work on the main body of the power tower 1 is completed, the staff opens the two mounting frames 4, removes the lifting device from the two steel cables 2, and then applies it to the maintenance work on other main bodies of the power tower 1 in the same way to achieve the lifting and support of the staff.

[0025] To facilitate the installation of the two lifting components 5 and the limiting component 6, and to allow the steel cable 2 to be inserted into the inner cavity of the mounting frame 4, as follows: Figure 6 and Figure 7 As shown, the mounting bracket 4 includes a fixed shell 41, with a placement hole 42 at the lower part of the fixed shell 41. Mounting shells 43 are slidably mounted on both sides of the outer surface of the fixed shell 41, and multiple buckles 44 are provided on the outer surface of the two mounting shells 43 away from the fixed shell 41.

[0026] Specifically, when the lifting device needs to be assembled onto the outer surface of the steel cable 2 or disassembled from the steel cable 2, the operator first unlocks the multiple buckles 44 on the two mounting shells 43 to release the locking state of the two mounting shells 43, and then drives the two mounting shells 43 to slide along the fixed shell 41 in a direction away from each other. During this process, the sliding rods on the outer surface of the two mounting shells 43 slide out along the inner cavity of the fixed shell 41.

[0027] Furthermore, after the two mounting shells 43 are opened, the staff can insert the steel cable 2 into the middle of the two mounting shells 43 through the placement hole 42, or release and separate the steel cable 2 from the placement hole 42.

[0028] In order to clamp the steel cable 2, and during the operation of the lifting component 5, the lifting component 5 drives the lifting device to move upward by clamping the steel cable 2, such as... Figure 8 and Figure 9 As shown, the lifting component 5 includes two drive wheel sets 51. The outer surfaces of the two drive wheel sets 51 are wound with mounting chains 52. The outer surfaces of the mounting chains 52 are provided with multiple clamping mechanisms 53. A motor 54 is provided on one side of the outer surface of the lower drive wheel set 51. The motor 54 is fixedly mounted on the outer surface of the mounting housing 43. A transmission mechanism 55 is provided on the other side of the outer surfaces of the two drive wheel sets 51. The multiple clamping mechanisms 53 are adapted to be used with the steel cable 2.

[0029] Specifically, when the staff opens the two mounting shells 43, the two mounting shells 43 will drive the two sets of mounting chains 52 to move away from each other. During this process, multiple clamping mechanisms 53 on the outer surface of the two sets of mounting chains 52 that are close to each other will be released from their clamping state. If the middle of these clamping mechanisms 53 has clamped the steel cable 2, these clamping mechanisms 53 will release the steel cable 2 under the action of the limiting component 6.

[0030] Furthermore, if the steel cable 2 is not clamped in the middle of the clamping mechanism 53, the operator can use a lifting device to insert the steel cable 2 into the middle of the two mounting shells 43 through the placement hole 42, and then lock and fix the two mounting shells 43. During this process, the multiple clamping mechanisms 53 on the outer surface of the two sets of mounting chains 52 that are close to each other will return to the clamping state under the action of the limiting component 6, and the multiple clamping mechanisms 53 on the outer surface of the two sets of mounting chains 52 that are close to each other are arranged at intervals.

[0031] Furthermore, after the multiple clamping mechanisms 53 have completed clamping and positioning the steel cable 2, the motor 54 outputs power to drive the transmission wheel set 51 located on the lower side to rotate, and then drives the transmission wheel set 51 located on the upper side to rotate synchronously through the transmission mechanism 55. The synchronous rotation of the two sets of transmission wheel sets 51 drives the mounting chain 52 to circulate, and then the mounting chain 52 drives the multiple clamping mechanisms 53 on its surface to move synchronously.

[0032] Furthermore, during the displacement of multiple clamping mechanisms 53, the clamping mechanism 53 that is not clamping the steel cable 2 will rotate from the upper transmission wheel set 51 to the side closer to the steel cable 2. During this process, the clamping mechanism 53 will clamp and position the surface of the steel cable 2 under the action of the limiting component 6. At the same time, the clamping mechanism 53 at the lower part of the side closer to the steel cable 2 will release the clamping action on the steel cable 2 under the action of the limiting component 6, and rotate to the side away from the steel cable 2 under the transmission action of the mounting chain 52. This cycle is repeated to achieve the continuous rise of the lifting device.

[0033] To achieve reliable clamping of the surface of the steel cable 2, such as Figure 10 As shown, the clamping mechanism 53 includes a mounting frame 531, which is fixedly mounted on the outer surface of the mounting chain 52. Two jaws 532 are symmetrically and rotatably mounted on one side of the inner surface of the mounting frame 531, and a connecting block 533 is slidably mounted on the other side of the inner surface of the mounting frame 531. The outer surfaces of the connecting block 533 are rotatably connected to the two jaws 532 via connecting rods. Both sides of the outer surfaces of the two jaws 532 are provided with connecting handles 536 that are rotatably mounted on the outer surface of the mounting frame 531. A pull rod 534 is slidably mounted on the inner wall of the mounting frame 531 on the side of the outer surface of the connecting block 533 away from the jaws 532. A sliding handle 535 is provided on the end face of the pull rod 534. Anti-slip strips are provided on the inner arc-shaped surfaces of the two jaws 532.

[0034] Specifically, during the cyclic displacement of the clamping mechanism 53 driven by the installation chain 52, the sliding handle 535 will slide along the inner cavity of the limiting component 6. When the clamping mechanism 53 moves from the upper transmission wheel set 51 to the side closer to the steel cable 2, the sliding handle 535 will move away from the steel cable 2 under the guidance of the limiting component 6. Then, the connecting block 533 will move synchronously through the pull rod 534. The connecting block 533 drives the two claws 532 to rotate towards each other through the connecting rod, thereby achieving clamping and positioning of the steel cable 2. The anti-slip strip on the inner arc surface of the claw 532 can effectively increase the friction coefficient between the claw 532 and the surface of the steel cable 2, and prevent clamping slippage.

[0035] Furthermore, when the clamping mechanism 53 is displaced to the lower part of the mounting chain 52 near the steel cable 2, it will rotate from the lower transmission wheel set 51 to the side of the mounting chain 52 away from the steel cable 2. During this process, the slide handle 535 will be displaced towards the steel cable 2 under the guidance of the limiting component 6. Then, through the transmission cooperation of the pull rod 534, the connecting block 533 and multiple connecting rods, the two claws 532 will be driven to rotate in a direction away from each other, thereby releasing the clamping action on the steel cable 2.

[0036] Example 2

[0037] This embodiment further improves upon Embodiment 1 by modifying the limiting component 6. To control the clamping and releasing actions of the multiple clamping mechanisms 53, such as... Figure 11 and Figure 12 As shown, the limiting component 6 includes a fixing frame 61, which is fixedly installed on the inner surface of the mounting shell 43. The upper and lower inner walls of the fixing frame 61 are rotatably connected to the middle of the outer surface of the two transmission wheel sets 51. Limiting mechanisms 62 are provided on both sides of the inner cavity of the fixing frame 61. Positioning mechanisms 65 are provided on both sides of the middle of the outer surface of the fixing frame 61. Both positioning mechanisms 65 are fixedly installed on the inner surface of the fixing shell 41.

[0038] Specifically, when the installation chain 52 drives the multiple clamping mechanisms 53 to circulate, the slide handle 535 will slide along the inner cavity of the two limiting mechanisms 62. Through the specific guide structure of the two limiting mechanisms 62, the slide handle 535 can be driven to move along a preset trajectory during the sliding process, thereby achieving precise control of the clamping and releasing actions of the clamping mechanism 53.

[0039] Furthermore, when the staff opens the two mounting shells 43, the two mounting shells 43 will drive the two lifting components 5 to move synchronously. During this process, the positioning mechanism 65 remains fixed, but the positioning mechanism 65 will drive the corresponding components of the limiting mechanism 62 to move, so that the multiple clamping mechanisms 53 near the steel cable 2 will switch from the clamping state to the releasing state.

[0040] To achieve precise control over the movement of clamping mechanism 53, such as Figure 12 As shown, the limiting mechanism 62 includes a vertical slide 621, which is fixedly installed on the inner surface of the fixed frame 61. Rotary slides 622 are provided on both sides of the outer surface of the vertical slide 621. A limiting member 623 is provided between the two rotary slides 622, and the limiting member 623 is slidably installed on the inner surface of the fixed frame 61.

[0041] Furthermore, such as Figure 13 and Figure 14As shown, the limiting member 623 includes a limiting slide 6231, which is slidably installed on the inner surface of the fixed frame 61. A plurality of springs 6232 are provided on one side of the outer surface of the limiting slide 6231, and one end face of each of the plurality of springs 6232 is fixedly connected to the inner surface of the fixed frame 61.

[0042] Furthermore, the vertical slide 621, the rotary slide 622, and the limiting slide 6231 are adapted to be used with the slide handle 535.

[0043] Specifically, when the slider 535 slides along the inner cavity of the vertical slide rail 621 with the mounting chain 52, since the vertical slide rail 621 is fixed vertically inside the fixed frame 61, it only guides the slider 535 and does not drive it to make lateral displacement. When the slider 535 slides into the inner cavity of the upper rotary slide rail 622, since the upper rotary slide rail 622 is a non-uniform radius semi-circular structure, its side near the limiting slide rail 6231 bends towards the vertical slide rail 621. Figure 13 As shown, when the slide handle 535 slides to the area of ​​the upper rotary slide 622 near the limiting slide 6231, the rotary slide 622 will drive the slide handle 535 to move towards the vertical slide 621, i.e. away from the steel cable 2, through its arc-shaped guide surface. During this process, the clamping mechanism 53 completes the clamping action of the steel cable 2.

[0044] Furthermore, when the sliding handle 535 slides from the upper rotary slide 622 to the inner cavity of the limiting slide 6231, since the limiting slide 6231 and the vertical slide 621 are both fixed in a vertical state inside the fixed frame 61, the clamping mechanism 53 maintains a continuous clamping state on the steel cable 2 during the sliding of the sliding handle 535 along the inner cavity of the limiting slide 6231.

[0045] Furthermore, when the slide handle 535 slides from the inner cavity of the limiting slide rail 6231 to the inner cavity of the lower rotary slide rail 622, since the lower rotary slide rail 622 and the upper rotary slide rail 6231 have the same structure and are installed in opposite directions, the slide handle 535 will be displaced away from the vertical slide rail 621 and closer to the steel cable 2 under the action of the arc-shaped guide surface of the lower rotary slide rail 622, thereby causing the clamping mechanism 53 to release the clamping state of the steel cable 2.

[0046] Furthermore, during the opening of the two mounting shells 43, some components of the lifting component 5 and the limiting component 6 are displaced synchronously with the mounting shell 43, but the positioning mechanism 65 will restrict the displacement of the limiting slide 6231. At this time, the clamping mechanism 53 is displaced synchronously with the mounting shell 43. During this process, the limiting slide 6231 is displaced relative to the slide handle 535, which can push the slide handle 535 to move closer to the steel cable 2, thereby releasing the clamping action of the clamping mechanism 53 which is in the state of clamping the steel cable 2.

[0047] To achieve precise limitation of the displacement stroke of the limit slide 6231, such as Figure 15 As shown, the positioning mechanism 65 includes an L-shaped rod 651, which is fixedly installed on the lower part of the inner surface of the fixed shell 41. A limiting frame 654 is provided on the upper part of the L-shaped rod 651. A fixing plate 652 is slidably installed in the middle of the inner cavity of the limiting frame 654. A plurality of springs 653 are provided on the side end face of the fixing plate 652 away from the L-shaped rod 651 and fixedly installed on the inner surface of the limiting frame 654. One side of the outer surface of the fixing plate 652 is fixedly connected to the outer surface of the corresponding limiting slide 6231.

[0048] Specifically, when the operator drives the two mounting shells 43 to move away from each other, the lifting component 5 and the limiting component 6 move synchronously with the mounting shells 43. At this time, the spring 6232 is in a compressed state and will apply an elastic thrust toward the steel cable 2 to the limiting slide 6231. During this process, the clamping mechanism 53 moves synchronously with the mounting shells 43, thereby releasing the clamping mechanism 53 on the side closer to the steel cable 2 from the clamping state of the steel cable 2. At this time, the spring 6232 returns to its natural extended state and no longer applies an elastic thrust to the limiting slide 6231.

[0049] Furthermore, when the clamping mechanism 53 near the steel cable 2 is released from its clamping state, the two mounting shells 43 continue to move away from each other. During this process, the limiting slide 6231 moves synchronously with the mounting shell 43, and the fixing plate 652 fixed to the limiting slide 6231 slides along the inner cavity of the limiting frame 654 until the mounting shell 43 moves to the preset position. At this time, the second spring 653 is compressed and stores force.

[0050] Furthermore, when the two mounting shells 43 are driven to move closer to each other, the limiting slide 6231 gradually returns to its initial position (i.e., the position that communicates with the inner cavity of the two rotary slides 622). At this time, the fixed frame 61 provides support and positioning for the limiting slide 6231, while the edges of the fixed plate 652 and the limiting frame 654 abut against each other and limit the movement. Through the double limiting of the fixed plate 652 by the fixed frame 61 and the limiting frame 654, the limiting slide 6231 can be prevented from generating additional displacement, thus ensuring the operational stability of the lifting device.

[0051] It should be noted that the specific installation method, circuit layout and connection method, and control method of the motor 54 used in the above embodiment are all conventional designs in the prior art, and will not be described in detail in this invention.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
