Description

Technical Field

[0001] This invention relates to the field of cableway removal construction equipment technology, and in particular to a locking mechanism for fixing pulley blocks during cableway removal construction. Background Technology

[0002] A cableway cable removal system is a specialized system used during cableway dismantling or maintenance. It is primarily used to efficiently remove cables from cableways. A cableway cable removal system typically consists of several key components, including: guide ropes: used to guide the direction of subsequent ropes or equipment, usually made of high-strength, abrasion-resistant materials; cableway crossover pulleys: employing an upper and lower pulley structure to carry and transport cables or equipment, ensuring smooth and safe movement during removal; locking and connecting ropes: used to connect and secure the cableway crossover pulleys, and to ensure the stability and safety of the entire removal system; support ropes: used to support and secure the cableway crossover pulleys, preventing them from swaying or falling off during removal; and traction equipment: such as winches and traction machines, used to provide the traction force required during removal.

[0003] The working principle of a cableway cable removal system is relatively complex, but it can be roughly summarized into the following steps: Preparation stage: First, a detailed inspection and evaluation of the cableway is required to determine the removal plan and safety measures. Then, the necessary equipment and materials, such as guide ropes, cableway crossover pulleys, locks, and connecting ropes, are prepared. Guide rope laying: Using personnel at height or drones, the guide ropes are laid to the predetermined positions to guide the subsequent removal work. Cableway crossover pulley installation: The cableway crossover pulleys are installed on the guide ropes, and the locks and connecting ropes are connected to ensure the stability and safety of the entire system. Support rope setting: As needed, support ropes are set below the cableway crossover pulleys to support and fix the pulleys, preventing them from swaying or falling off during the removal process. Traction removal: Using traction equipment to provide traction force, the cables, baskets, or other equipment on the cableway are gradually removed using the cableway crossover pulleys.

[0004] Cableway removal systems are widely used in cableway dismantling, maintenance, and cable laying and removal across complex terrain. During cableway removal, pulley blocks are used to connect the supporting rope and the cable to be removed, using the pulley blocks to pull the cable away. Due to the large span and heavy weight of the cableway, multiple pulley blocks are required in practice. This reduces the efficiency of the pulley blocks during removal and makes it difficult to ensure effective locking to prevent loosening or detachment during movement. This can lead to rope loss of control, increasing safety hazards in the overall removal project. Furthermore, the pulley blocks may jump out of their grooves due to the inability to withstand vibrations and impacts during cableway operation. The large span of the removal process also makes it difficult to monitor the working status of multiple pulley blocks, hindering control of the construction process and increasing safety risks. Summary of the Invention

[0005] In order to solve the technical problem that pulley blocks in cableway dismantling systems are not easy to fix and lock quickly, this invention provides a locking mechanism for fixing pulley blocks during cableway dismantling construction.

This connects the supporting rope and the conductor to be removed, facilitating the slow and stable removal of the cableway. The supporting rope and pulley blocks are then dismantled sequentially to complete the removal process. Locking components are installed on the pulley blocks for stable locking, ensuring they can withstand vibrations and impacts that may occur during the removal process. This guarantees a stable connection and facilitates subsequent sequential traction. Multiple pulley blocks are used for stable cableway removal. The locking components allow for quick and easy connection with the supporting rope and ensure stability after locking, preventing loosening. A connecting structure connects the pulley blocks to the conductor to be removed, and connecting components enable traction across the lines, ensuring stable removal of the conductor. Pressure monitoring of each pulley block allows for monitoring of the traction force during removal, ensuring real-time control of the system and significantly improving work efficiency and safety while reducing manpower and material costs.

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0030] like Figure 1-10 As shown, the locking mechanism for fixing the pulley block during cableway removal construction includes: The upper pulley assembly 100 is composed of a wheel seat 101. The wheel seat 101 is provided with an upper pulley 104 for connecting with the supporting rope. An opening 108 for fixing the pulley group is provided on one side of the wheel seat 101. A locking assembly 200 is provided inside the wheel seat 101 and is correspondingly arranged below the upper pulley 104. A lower pulley assembly 400 is connected to an upper pulley assembly 100 via a connecting assembly 300. The connecting assembly 300 at the connection point with the upper pulley assembly 100 is provided with a buffer structure. The lower pulley assembly 400 is composed of a wheel shell 401. The bottom of the wheel shell 401 is provided with symmetrically distributed fixed side plates 402 and movable side plates 403. A lower pulley 405 connected to the cableway line is provided between the fixed side plates 402 and the movable side plates 403. The side wall of the fixed side plate 402 is provided with a clamping structure, and the side wall of the movable side plate 403 is provided with a monitoring structure. The bottom of the fixed side plate 402 and the movable side plate 403 is provided with a connecting structure located below the lower pulley 405.

[0031] The wheel seat 101 has a C-shaped structure. The wheel seat 101 located above the opening 108 is rotatably connected to the rotating shaft 103. The rotating shaft 103 is fitted with a bearing 102 located inside the wheel seat 101. The rotating shaft 103 is fixedly connected to the upper pulley 104. The outer wall of the wheel seat 101 located below the opening 108 is fixedly connected to a threaded rod 109, and the end of the threaded rod 109 is threadedly connected to a nut 110. A stabilizing structure is fixedly connected to the side of the wheel seat 101 away from the threaded rod 109. The stabilizing structure consists of a support rod 106 and a roller 107. The support rod 106 is fixedly connected to the inner wall of the wheel seat 101, and the end of the support rod 106 is rotatably connected to the roller 107. The side wall of the upper pulley 104 has an annular groove 105, and the roller 107 extends into the groove 105 and contacts the upper pulley 104.

[0032] In this technical solution, the upper pulley 104 rotates inside the wheel seat 101 via the rotating shaft 103, and its stable rotation is achieved via the bearing 102. When the upper pulley 104 rotates, the roller 107 rotates inside the groove 105, further ensuring the rotational stability of the upper pulley 104. An opening 108 is provided for the connection between the wheel seat 101 and the supporting rope. During installation, simply open the locking assembly 200, pass the wheel seat 101 through the supporting rope, place the upper pulley 104 on the supporting rope, and then close the locking assembly 200 to achieve the connection.

[0033] The locking assembly 200 includes a pressure plate 201 and a lever 202. The pressure plate 201 has an arc-shaped structure and is rotatably connected to the inner wall of the wheel seat 101. One end of the pressure plate 201 is provided with the lever 202, the middle of which is rotatably connected to the inner wall of the wheel seat 101. The lever 202 has an L-shaped structure and one end contacts the locking structure. There are two levers 202, symmetrically arranged on one side of the inner wall of the wheel seat 101, and the adjacent ends of the two levers 202 contact the bottom of the pressure plate 201. An arc-shaped guide strip 203 is fixedly connected to the inner wall of the wheel seat 101. The bottom of the clamping plate 204 has a notch that mates with the guide strip 203, and the clamping plate 204 at the notch is slidably connected to the surface of the guide strip 203. The locking structure consists of the clamping plate 201... Composed of clamping plate 204 and limiting plate 206, clamping plate 204 is rotatably connected to the inner wall of the top of wheel seat 101, clamping plate 204 is fixedly connected to a U-shaped clamping block 205 in the middle, clamping plate 204 has two clamping plates 204, and the bottom ends of the clamping plates 204 are in contact with the top of lever 202. The clamping blocks 205 in the middle of the two clamping plates 204 are in contact with each other, and a bearing 102 is provided between the clamping blocks 205. Limiting plate 206 is rotatably connected to the outer wall of the top of wheel seat 101. Limiting plate 206 has a U-shaped structure and a slot at the bottom that matches the threaded rod 109. Nut 110 is in contact with the surface of limiting plate 206. Limiting rods 207 are fixedly connected to both sides of limiting plate 206. The limiting rods 207 extend into the opening 108 and are located on both sides of clamping plate 204.

[0034] In this technical solution, when the locking assembly 200 is opened, the connecting assembly 300 is lifted upwards. The compressed return spring 208 pushes the push plate 209 upwards, causing the push plate 209 to push the pressure plate 201 to rotate upwards. After the pressure plate 201 separates from the lever 202, the lever 202 is rotated so that its end is raised and the raised part is located between the two clamping plates 204. At this time, the other end of the lever 202 rotates to the bottom of the clamping plate 204. Then, the clamping plates 204 are rotated to both sides to move away from the opening 108, and the wheel seat 101 is installed. After installation, the return clamping plate 204 drives the clamping block 205 to abut against the bearing 102 to ensure the rotational stability of the upper pulley 104. Then, the connecting assembly 300 is pulled down so that the pressure plate 201 presses against the push plate 209 and the lever 202. The lever 202 abuts against the bottom of the limiting plate 206 to achieve stable locking.

[0035] The bottom of the wheel seat 101 is connected to the push plate 209 via a return spring 208. The push plate 209 contacts the bottom of the pressure plate 201, and a buffer structure is movably sleeved inside the push plate 209. The wheel seats 101 located on both sides of the push plate 209 are fixedly connected to the first connecting block 210, and each first connecting block 210 is fixedly connected to the first horizontal rope 211. The top two sides of the wheel shell 401 are fixedly connected to the second connecting block 414, and each second connecting block 414 is fixedly connected to the second horizontal rope 415. The first horizontal rope 211 and the second horizontal rope 415 are both connected to another set of pulleys. The connecting assembly 300 is composed of a connecting rope 301. Each end of the connecting rope 301 is provided with a hook 302, and both ends of the connecting rope 301 located at the hook 302 are fixedly sleeved with locking sleeves 30. 3. One end of the connecting rope 301 is connected to the buffer structure via a hanging ring 304. The buffer structure consists of a guide rod 305 and a guide sleeve 306. The guide rod 305 is fixedly connected to one end of the hanging ring 304, and the guide rod 305 is movably sleeved inside the guide sleeve 306. The guide sleeve 306 passes through the push plate 209 and the pressure plate 201 respectively. The guide sleeve 306 located above the pressure plate 201 is fixedly connected to an end 307. The bottom of the wheel seat 101 has a round hole for the movement of the connecting component 300. A fixed shaft 308 is fixedly connected to the surface of the guide sleeve 306. The fixed shaft 308 is connected to the end of the hanging ring 304 via a buffer spring 309, and the buffer spring 309 is sleeved on the surface of the guide sleeve 306. The other end of the connecting rope 301 is connected to the wheel housing 401 via a hook 302.

[0036] In this technical solution, adjacent pulley blocks are connected by a first horizontal rope 211 and a second horizontal rope 415 to achieve stable traction of the conductor to be removed. The upper pulley assembly 100 is installed on the supporting rope to provide tension. The conductor to be removed on the lower pulley assembly 400 is pulled by the connecting assembly 300, and the resulting tension causes the buffer spring 309 to stretch. At this time, the relative movement between the guide rod 305 and the guide sleeve 306 achieves a uniform tension effect, and the resulting tension causes the end 307 to force the pressure plate 201 to rotate. The pressure plate 201 abuts against the lever 202 to effectively lock the wheel seat 101. Then, the limiting plate 206 is rotated to the surface of the wheel seat 101, and the limiting rod 207 is driven to pass through the opening 108 and move to both sides of the clamping plate 204. The nut 110 is tightened on the threaded rod 109 to fix the limiting plate 206, further ensuring the stability performance after locking.

[0037] A fixed side plate 402 is fixedly connected to the bottom of the wheel housing 401, and a movable side plate 403 is rotatably connected to the other side of the bottom of the wheel housing 401. A movable block 404 is slidably connected to the side wall of the movable side plate 403. A slide rail is fixedly connected to the inner wall of the movable side plate 403, and a slide groove that matches the slide rail is opened inside the movable block 404. The movable block 404 is rotatably connected to the lower roller 405, and a shaft sleeve 406 is fixedly connected to the other side of the lower roller 405. The shaft sleeve 406 is sleeved with the clamping structure box. The clamping structure is composed of a pin 407. The two ends of the pin 407 have square and circular cross sections, respectively. One end of the pin 407 is movably sleeved inside the square hole opened in the fixed side plate 402, and the other end of the pin 407 is movably inserted into the shaft sleeve 406. A movable plate 408 is rotatably connected to the outer wall of the fixed side plate 402, and the inner wall of the movable plate 408 is in contact with the pin 407.

[0038] In this technical solution, after rotating the movable side plate 403 to place the wire to be removed under the wheel housing 401, the movable side plate 403 is reset and drives the lower pulley 405 to move to a horizontal position. The pin 407 is inserted so that its end moves into the bushing 406 and the two are connected, thereby locking the lower pulley assembly 400. Then, the long screw 409 is rotated to a horizontal position, and the screw sleeve 410 is passed through the long hole 411 and connected to the long screw 409. The cooperation between the long screw 409 and the screw sleeve 410 presses the movable plate 408. The movable plate 408 abuts against the pin 407 to achieve a limit. At the same time, the fixed side plate 402 and the movable side plate 403 are fixed to each other, thereby achieving stable fixation of the lower pulley assembly 400.

[0039] The monitoring structure consists of a piezoelectric device 412, which is fixedly installed on the inner wall of the movable side plate 403. The piezoelectric device 412 is correspondingly positioned below the movable block 404. A signal sensor 413 is fixedly connected to the outer wall of the movable side plate 403, and the signal sensor 413 is electrically connected to the piezoelectric device 412. The connection structure consists of a long screw 409 and a screw sleeve 410. The long screw 409 is rotatably connected to the bottom side wall of the movable side plate 403, and the other end of the long screw 409 is threaded into the inside of the screw sleeve 410. The bottom of both the fixed side plate 402 and the movable plate 408 are provided with correspondingly distributed elongated holes 411. The screw sleeve 410 is movably connected to the inside of the elongated holes 411, and the end of the screw sleeve 410 contacts the side wall of the movable plate 408.

[0040] In this technical solution, when the pulley 405 is subjected to pressure, it moves downward slightly. At this time, the movable block 404 contacts the piezoelectric device 412. The pressure generated by the piezoelectric device 412 creates a potential difference. The signal sensor 413 receives the data signal, amplifies it, and transmits it to the back end of the line-pulling system. This enables the monitoring of the traction signal of each pulley group, which is used for real-time control of the line-pulling force throughout the process, effectively ensuring safety performance.
