Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to a power high-altitude hoisting equipment and its usage method. Background Technology

[0002] For a long time, spacer installation was done manually using a mobile crane. Mechanized methods only involved pre-installation using spacer installation robots, followed by manual inspection for any installation defects. For example, Chinese patent CN202211043945.2 discloses a spacer installation robot consisting of a working device and a hoisting device. The working device is located at the lower end of the split conductor, and the hoisting device is located at the upper end, connected by ropes. The working device includes a vehicle body with walking devices on both sides. The hoisting device includes wheels and a winch mechanism with ropes attached to the winch mechanism, which are placed in pulleys on the outside of the winch mechanism. The hoisting device also has a protective cover with hooks on top. This invention is quite complex, using four ropes for hoisting, and its hoisting power unit and winch are located on the conductor, resulting in excessive weight for the hoisting device itself, making it difficult to lift onto the conductor. Furthermore, this invention does not consider the risk of a fall from a height due to rope breakage during hoisting, posing a significant safety hazard. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects and problems of poor safety in existing hoisting devices, and to provide a safer high-altitude power hoisting device and its usage method.

[0004] To achieve the above objectives, the technical solution of the present invention is: a power high-altitude hoisting device, comprising an upper hoisting device, a lower hoisting device, and a hoisting rope. The upper hoisting device is movably connected to the upper side of the split conductor along the length direction of the split conductor.

The docking self-locking device is connected to the upper side of the lower lifting frame.

[0009] The rope guide includes a cable tray, a guide rail, a screw, a slide, two cable guide wheels, two rollers, and two guide wheels. The guide rail is connected to the cable tray, and the screw is threaded to the cable tray. The output end of the drive motor is connected to a dual-output shaft reducer.

The slide is threaded to the screw. The two rollers are rotatably connected to one side of the slide and roll in cooperation with the upper and lower end faces of the guide rail, respectively. The two cable guide wheels and the guide wheels are both horizontally rotatably connected to the slide. The guide wheels and the cable guide wheels are arranged perpendicular to each other, and the guide wheels and the cable guide wheels together form a cavity for the passage of the suspension rope.

[0010] The docking self-locking device includes a mounting base, a power unit, a transmission gear set, a self-locking pin, and a rotating sleeve. The mounting base is connected to the upper side of the lower lifting frame, the power unit is mounted on the mounting base, the rotating sleeve is rotatably connected to the upper side of the lower lifting frame, the self-locking pin is connected to the upper end of the rotating sleeve and arranged relative to the docking base, and the first and last ends of the transmission gear set are respectively installed at the output end of the power unit and the lower end of the rotating sleeve.

The fixing plate is threaded to the left threaded section. The clamping plate is threaded to the right threaded section. The clamping plate and the fixing plate together form a slot for accommodating split wires.

[0012] A fall protection device is connected between the upper and lower hoisting devices. The fall protection device includes an upper safety rope reel, a safety fixing seat, a safety rope, a fall arrestor, a shackle, and a lower safety rope reel. The safety fixing seat is connected to the upper side of the upper hoisting device. The upper safety rope reel is rotatably connected to the safety fixing seat. One end of the safety rope is wound around the upper safety rope reel. The shackle and the lower safety rope reel are installed sequentially from top to bottom on the outside of the lower hoisting device. The other end of the safety rope is wound around the lower safety rope reel. The fall arrestor is slidably connected to the outer circumference of the safety rope. The lower side of the fall arrestor is connected to the upper side of the shackle via a hanging rope.

[0013] The fall arrestor includes a rotating hook, a main frame, and a guide wheel.

The main frame is sleeved on the outer circumference of the safety rope, and the guide wheel is rotatably connected to the main frame and tumbledly connected to the safety rope.

[0014] A cushioning airbag is installed on the lower side of the lower hoisting device.

[0015] A method of using a power high-altitude hoisting device, the method comprising the following steps:

[0016] First, install the upper hoisting device on the upper side of the split conductor. Then, connect and fix the upper hoisting device to the split conductor using a wire clamp. Then, release the hoisting rope and safety rope from the upper hoisting device and the upper safety rope reel respectively, so that the hoisting rope is lowered from the high altitude to the ground.

[0017] The hoisting rope is wound around the lower hoisting device, and the safety rope is passed through the main frame and wound around the lower safety rope reel. Then, the hoisting rope and safety rope are retrieved through the upper hoisting device and the upper safety rope reel to lift the lower hoisting device. The rise of the lower hoisting device causes the hanging rope and rotating hook to move upward, and the rotating hook causes the main frame to move upward on the safety rope.

[0018] If the hoisting rope suddenly breaks during the ascent of the lower hoisting device, the lower hoisting device will fall downwards. The lower hoisting device will drive the rotating hook to rotate on the main frame through the hanging rope, so that the rotating hook abuts against the safety rope, and the main frame will be stuck on the safety rope. At this time, the lower hoisting device will stop falling. The lower hoisting device will be removed and placed on the ground. The hoisting rope will be replaced and wound around the lower hoisting device. The above operation will be repeated to lift the lower hoisting device.

[0019] When the upper side of the lower hoisting device comes into contact with the upper hoisting device, the lower hoisting device and the upper hoisting device are locked together by the docking self-locking device, and the docking is completed at this time.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this invention, a power high-altitude hoisting device and its usage method are disclosed. The device employs a design with upper and lower hoisting devices, primarily arranging the hoisting structure on the lower hoisting device, significantly reducing the weight of the upper hoisting device and facilitating its installation. A self-locking docking device is designed to securely lock the upper and lower devices together, preventing accidents caused by rope breakage and subsequent falls from height. A wire clamp is also designed to prevent movement of the upper hoisting device during hoisting. Therefore, this invention offers good safety and high stability.

[0022] 2. In the power high-altitude hoisting equipment and its usage method of the present invention, the device is guided for the first time by a limiting plate and a docking guide plate, and then guided for the second time by a docking base and a docking self-locking device. This two-stage guidance ensures that the upper and lower devices are precisely docked, guaranteeing stable operation during the hoisting process. The design is simple and the structure is compact. Therefore, the present invention has a compact structure and high stability.

[0023] 3. In the power high-altitude hoisting equipment and its usage method of the present invention, considering the potential fall prevention problem during hoisting, additionally designed safety ropes and fall arrestors are used to prevent the lower hoisting device from falling during hoisting. Simultaneously, a safety airbag is installed under the base, providing dual protection during the hoisting process. Therefore, the present invention has high reliability and high safety.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] See Figures 1 to 10 A power high-altitude hoisting device includes an upper hoisting device 1, a lower hoisting device 2, and a hoisting rope 3. The upper hoisting device 1 is movably connected to the upper side of the split conductor 6 along the length direction of the split conductor 6. A wire clamp 17 for clamping the split conductor 6 is connected to the lower side of the upper hoisting device 1. The lower hoisting device 2 is arranged relative to the upper hoisting device 1 and located on the lower side of the split conductor 6. The two ends of the hoisting rope 3 are respectively connected to the upper hoisting device 1 and the lower hoisting device 2. A docking self-locking device 24 is installed on the upper side of the lower hoisting device 2.

[0038] The upper hoisting device 1 is used to lift the lower hoisting device 2 using the hoisting rope 3;

[0039] The docking self-locking device 24 is used to connect and fix the upper hoisting device 1 and the lower hoisting device 2 after the lower hoisting device 2 is lifted to contact the upper hoisting device 1.

[0040] In this embodiment, since the lifting power unit is installed on the lower lifting device 2, the upper lifting device 1 is relatively lightweight. It can be lifted onto the line by drone or manual assistance. Once the wire clamp 17 is firmly fixed to the split conductor 6, it can be ensured that the upper lifting device 1 will not fall off the conductor. The wire clamp 17 can automatically control the clamping or releasing of the split conductor 6, or it can be manually controlled.

[0041] Example 2:

[0042] The basic content is the same as in Example 1, except that:

[0043] See Figures 2 to 5 The upper lifting device 1 includes an upper lifting frame 11, a rope winding drum 12, a rope pressure plate 13, a docking base 14, and a limiting plate 15. The upper lifting frame 11 is horizontally arranged and located above the split conductor 6. A pulley 18 is rotatably connected to the top corner of the upper lifting frame 11, and the pulley 18 is rotatably connected to the upper side of the split conductor 6. The limiting plate 15 and the docking base 14 are respectively connected to the lower side of the upper lifting frame 11. The limiting plate 15 has multiple mounting holes 19 that cooperate with the lower lifting device 2. A rotatably connected component is located on the lower side of the limiting plate 15. For the anti-scratch roller 16, the docking base 14 is connected to the docking self-locking device 24. The rope take-up drum 12 is arranged horizontally and rotatably connected to the upper side of the upper lifting frame 11. The rope pressure plate 13 is located on the upper side of the rope take-up drum 12. One end of the rope 3 is wrapped around the rope take-up drum 12. The other end of the rope 3 abuts against the lower side of the rope pressure plate 13 and then passes through the upper lifting frame 11, the limiting plate 15, and a pair of anti-scratch rollers 16 in sequence before being connected to the lower lifting device 2. The wire clamp 17 is connected to the upper side of the upper lifting frame 11.

[0044] The lower lifting device 2 includes a self-winding reel 21, a rope arranger 22, a docking guide plate 23, a lower lifting frame 25, and a drive motor 26. The lower lifting frame 25 is located below the split conductor 6. The self-winding reel 21 is horizontally arranged and rotatably connected to the lower lifting frame 25. The output end of the drive motor 26 is connected to one side of the self-winding reel 21. The rope arranger 22 is connected to the upper side of the lower lifting frame 25. The other end of the lifting rope 3 passes through the rope arranger 22 and is wound around the self-winding reel 21. The docking guide plate 23 is connected to the upper side of the lower lifting frame 25 and is arranged in a one-to-one correspondence with the mounting holes 19. The docking self-locking device 24 is connected to the upper side of the lower lifting frame 25.

[0045] In this embodiment, after the upper hoisting device 1 is fixed, its multiple rope winding drums 12 and upper safety rope reel 41 begin to lower the hoisting rope 3 and safety rope 43 from the height to the ground. The hoisting rope pressure plate 13 prevents the hoisting rope 3 from slipping out of the rope winding drum 12, avoiding rope jamming during high-altitude release. The anti-scratch roller 16 allows the hoisting rope 3 to pass through the two rollers, changing from sliding friction to rolling friction, preventing the hoisting rope 3 from being scratched and broken. Then, ground personnel connect the hoisting rope 3 to the self-winding reel 21 and rope guide 22 of the lower hoisting device 2. At this point, all ground preparations are complete.

[0046] During lifting, the self-winding reel 21 winds the lifting rope 3 onto its drum, slowly lifting the lower lifting device 2 until the multiple front, rear, left, and right docking guide plates 23 installed on the lower lifting frame 25 contact the limiting plate 15 on the upper lifting device 1. At this point, the first guiding action occurs, and the docking guide plates 23 pass through the multiple mounting holes 19 on the limiting plate 15, guiding the frame of the upper lifting frame 11. Then, the self-winding reel 21 continues to work, continuing to lift the lower lifting device 2 until the lower lifting device 2 and the upper lifting device 1 are in complete contact without gaps. At this point, the docking work is completed.

[0047] Example 3:

[0048] The basic content is the same as Example 2, except that:

[0049] See Figures 6 to 7The rope guide 22 includes a cable guide seat 221, a guide rail 222, a screw 223, a slide 224, two cable guide wheels 226, two rollers 225, and two guide pulleys 227. The guide rail 222 is connected to the cable guide seat 221, and the screw 223 is threadedly connected to the cable guide seat 221. The output end of the drive motor 26 is connected to a dual-output shaft reducer 27. One output shaft of the dual-output shaft reducer 27 is connected to one side of the self-winding reel 21, and the other output shaft of the dual-output shaft reducer 27 is connected to a drive pulley 228. One end of the screw 223 passes through... The cable tray 221 is connected to a driven pulley 229. The outer circumferential surfaces of the driving pulley 228 and the driven pulley 229 are wound with a synchronous belt 220. The slide 224 is threaded to the screw 223. The two rollers 225 are rotatably connected to one side of the slide 224 and respectively roll in cooperation with the upper and lower end faces of the guide rail 222. The two cable trays 226 and the guide rollers 227 are horizontally rotatably connected to the slide 224. The guide rollers 227 and the cable trays 226 are arranged perpendicular to each other. The guide rollers 227 and the cable trays 226 together form a cavity for the suspension rope 3 to pass through.

[0050] In this embodiment, the drive motor 26 drives the dual-output shaft reducer 27 to work, which in turn drives the self-winding reel 21 to rotate and wind the hoisting rope 3 onto its drum. At the same time, the dual-output shaft reducer 27 drives the drive pulley 228 to rotate, which in turn drives the driven pulley 229 to rotate via the synchronous belt 220, thereby driving the screw 223 to rotate and causing the slide block 224 to move on the screw 223, thus controlling the hoisting rope 3 to achieve automatic positioning.

[0051] Example 4:

[0052] The basic content is the same as Example 2, except that:

[0053] See Figure 8 The docking self-locking device 24 includes a mounting base 244, a power device 245, a transmission gear set 243, a self-locking pin 241, and a rotating sleeve 242. The mounting base 244 is connected to the upper side of the lower lifting frame 25. The power device 245 is mounted on the mounting base 244. The rotating sleeve 242 is rotatably connected to the upper side of the lower lifting frame 25. The self-locking pin 241 is connected to the upper end of the rotating sleeve 242 and arranged relative to the docking base 14. The first end and the last end of the transmission gear set 243 are respectively mounted on the output end of the power device 245 and the lower end of the rotating sleeve 242.

[0054] In this embodiment, when the self-locking pins 241 on the docking self-locking device 24 contact the docking bases 14 installed at the four corners of the upper hoisting device 1, the second guiding action is activated. Through the pyramid-shaped guides designed on the self-locking pins 241, the pins pass directly through the internal space of the docking base 14 until the lower hoisting device 2 and the upper hoisting device 1 are in complete contact without gaps, at which point the docking operation is complete. Then, the power unit 245 on the docking self-locking device 24 starts, transmitting torque to the self-locking pins 241 through the transmission gear set 243. The self-locking pins 241 rotate 90° around the rotating sleeve 242, from the elongated hole parallel to the docking base 14 (along the guide wire direction) to a direction perpendicular to the guide wire direction. The self-locking pins 241 can no longer pass through the elongated hole of the docking base 14, thus all four corner docking self-locking devices 24 complete their self-locking action, and the lower hoisting device 2 and the upper hoisting device 1 are firmly locked together and cannot be separated, ensuring the safety of subsequent operations. The self-locking pin 241 serves both as a guide and a lock. The spiral step designed on it can compensate for errors caused during processing to a certain extent and improve the locking force.

[0055] Example 5:

[0056] The basic content is the same as Example 2, except that:

[0057] See Figure 4 The wire clamp 17 includes a wire clamping base 171, a slide rail 172, a bidirectional screw 173, a fixing plate 174, and a clamping plate 175. The wire clamping base 171 is connected to the lower side of the upper hoisting device 1. The slide rail 172 is connected to the wire clamping base 171. The bidirectional screw 173 is threaded to the wire clamping base 171. The bidirectional screw 173 has a left threaded section and a right threaded section. The thread direction of the left threaded section is opposite to that of the right threaded section. The fixing plate 174 is threaded to the left threaded section. The clamping plate 175 is threaded to the right threaded section. The clamping plate 175 and the fixing plate 174 together form a slot for accommodating the split wire 6.

[0058] In this embodiment, one end of the bidirectional screw 173 is connected to a drive device. When the upper hoisting device 1 is installed on the split conductor 6, the drive device controls the bidirectional screw 173 to rotate, causing the clamping plate 175 and the fixing plate 174 to move towards each other and clamp the split conductor 6. After the lower hoisting device 2 is connected and fixed to the upper hoisting device 1, the drive device controls the bidirectional screw 173 to rotate in the opposite direction, causing the clamping plate 175 and the fixing plate 174 to move away from each other and release the split conductor 6, so as to carry out the subsequent spacer bar installation operation.

[0059] Example 6:

[0060] The basic content is the same as in Example 1, except that:

[0061] See Figure 1 , Figure 9 and Figure 10 A fall arrestor 4 is connected between the upper hoisting device 1 and the lower hoisting device 2. The fall arrestor 4 includes an upper safety rope reel 41, a safety fixing seat 42, a safety rope 43, a fall arrestor 44, a lifting ring 46, and a lower safety rope reel 47. The safety fixing seat 42 is connected to the upper side of the upper hoisting device 1. The upper safety rope reel 41 is rotatably connected to the safety fixing seat 42. One end of the safety rope 43 is wound around the upper safety rope reel 41. The lifting ring 46 and the lower safety rope reel 47 are installed sequentially from top to bottom on the outside of the lower hoisting device 2. The other end of the safety rope 43 is wound around the lower safety rope reel 47. The fall arrestor 44 slides. The lower side of the fall arrester 44 is connected to the upper side of the hanging ring 46 via a hanging rope 45 and is connected to the outer peripheral surface of the safety rope 43. The fall arrester 44 includes a rotating hook 441, a main frame 442 and a guide wheel 443. The rotating hook 441 is hinged to the main frame 442. One end of the rotating hook 441 is connected to the hanging rope 45 and the other end of the rotating hook 441 abuts against the safety rope 43. The main frame 442 is sleeved on the outer peripheral surface of the safety rope 43. The guide wheel 443 is rotatably connected to the main frame 442 and rollably connected to the safety rope 43. A buffer airbag 5 is installed on the lower side of the lower hoisting device 2.

[0062] Example 7:

[0063] A method of using the power high-altitude hoisting equipment described in Embodiment 6, the method comprising the following steps:

[0064] First, install the upper hoisting device 1 on the upper side of the split conductor 6, then connect and fix the upper hoisting device 1 to the split conductor 6 through the wire clamp 17, and then release the hoisting rope 3 and the safety rope 43 through the upper hoisting device 1 and the upper safety rope reel 41 respectively, so that the hoisting rope 3 is lowered from the high air to the ground.

[0065] The hoisting rope 3 is wound around the lower hoisting device 2, and the safety rope 43 is passed through the main frame 442 and wound around the lower safety rope reel 47. Then, the hoisting rope 3 and the safety rope 43 are retrieved through the upper hoisting device 1 and the upper safety rope reel 41, and the lower hoisting device 2 is lifted. The rise of the lower hoisting device 2 drives the hanging rope 45 and the rotating hook 441 to move upward. The rotating hook 441 drives the main frame 442 to move upward on the safety rope 43.

[0066] If the hoisting rope 3 suddenly breaks during the ascent of the lower hoisting device 2, the lower hoisting device 2 will fall downwards. The lower hoisting device 2 will drive the rotating hook 441 to rotate on the main frame 442 through the hanging rope 45, so that the rotating hook 441 abuts against the safety rope 43, and the main frame 442 is locked on the safety rope 43. At this time, the lower hoisting device 2 will stop falling. The lower hoisting device 2 will be removed and placed on the ground. The hoisting rope 3 will be replaced and wound around the lower hoisting device 2. The above operation will be repeated to lift the lower hoisting device 2.

[0067] When the upper side of the lower hoisting device 2 contacts the upper hoisting device 1, the lower hoisting device 2 and the upper hoisting device 1 are locked together by the docking self-locking device 24, and the docking is completed.

[0068] In this embodiment, the buffer airbag 5 is a device installed at the bottom of the lower hoisting device 2. If the fall protection device 4 fails, the buffer airbag 5 will play a final protective role. When the equipment detects that the acceleration of the lower hoisting device 2 is too large, the buffer airbag 5 will open and inflate to its maximum to buffer and unload the force, preventing the equipment from being damaged by falling.
