Description

Technical Field

[0001] This invention relates to the field of power construction, specifically to a cargo transport ropeway system for power construction. Background Technology

[0002] Due to the complex terrain of hilly, mountainous, and high-altitude areas, freight cableway technology is often used to transport construction materials in power transmission line construction. Freight cableways are widely used in power construction projects in complex terrains such as high altitude and mountainous areas because of their advantages such as high efficiency, low energy consumption and environmental protection.

[0003] Freight cableways commonly use circulating cableways. Circulating cableways have transmission devices at both the loading and unloading stations, and traction cables connecting the two transmission devices are installed end-to-end. Transport containers are fixed to the traction cables by grippers, thus enabling the transport containers to move cyclically between the loading and unloading stations.

[0004] However, in the construction of freight cableways for traditional power transmission line projects, due to the limitations of the cable grippers and cableway structure, the cableway must be stopped before loading and unloading materials. The impact force generated by frequent starts and stops can easily cause uneven stress and metal fatigue to the traction cable wire rope and other structures, and seriously restricts the transportation progress of construction materials, thus causing the overall project progress to lag behind. Summary of the Invention

[0005] The purpose of this invention is to provide a cableway system for transporting goods in power construction, which solves the problem in the prior art where the cableway is limited by the gripper and cableway structure, requiring the cableway to be stopped before loading and unloading. The impact force generated by frequent starts and stops can easily cause uneven stress and metal fatigue to the traction cable and other structures, and seriously restricts the transportation progress of construction materials, thus causing delays in the overall project progress.

[0006] The technical solution adopted in this invention is as follows: a cargo transport cableway system for power construction, including a cargo tunnel, wherein saddles are evenly arranged on the track cable in the cargo tunnel, and cargo baskets are connected to the saddles through a quick-connect mechanism, and cargo platforms are set on the ground at both the loading station and the unloading station;

[0007] The quick-connect mechanism includes a plug structure and a socket structure;

[0008] The plug structure includes a traction rod fixed vertically to the top of the cargo basket and a connecting rod fixed to the side of the traction rod.

[0009] The socket structure includes a fixed plate installed at the end of the saddle. A rotating rod is coaxially arranged on the fixed plate. The upper end of the rotating rod passes through the fixed plate and is coaxially arranged with a limiting cap for limiting its axial position. The lower end of the rotating rod is connected to a mounting box. A drive gear is arranged at the rear of the mounting box. A bidirectional lead screw is coaxially arranged on the drive gear. The end of the bidirectional lead screw away from the drive gear extends into the mounting box. Bidirectional lead screw sliders are installed on its threads with different directions of rotation. Movable plates are connected to the sides of the bidirectional lead screw sliders. Semi-circular clamping plates are installed on the opposite surfaces of the movable plates.

[0010] A passive clamping drive structure is provided at both the loading station and the unloading station along the running direction of the socket structure.

[0011] The passive clamping drive structure includes a channel steel with the same installation height as the drive gear and a bracket for fixing the channel steel. One of the wing plates of the channel steel is provided with a pull-out rack that meshes with the drive gear. The pull-out rack is installed in opposite positions on the channel steel of the loading station and the unloading station.

[0012] The rotating rod is coaxially mounted with double rails. Along the cableway running direction, a passive reversing drive structure is symmetrically mounted in front of the cargo platform. The passive reversing drive structure is also fixed by a bracket. A steering rack is provided on the side of the passive reversing drive structure on one of the brackets near the rotating rod. The steering rack is at the same height as the double rails, and the number of teeth on the steering rack is half the number of teeth on the double rails.

[0013] Furthermore, a clamping self-locking structure is installed on the side of the drive gear, and a strong magnet for triggering the clamping self-locking structure is installed at the rear of the channel steel.

[0014] The clamping self-locking structure includes a fixed cylinder arranged parallel to the bidirectional lead screw. One end of the fixed cylinder is fixed to the mounting box, and a moving rod is inserted into the other end. A locking tooth is fixed on the side of the moving rod away from the fixed cylinder and close to the drive gear. The locking tooth extends to the teeth of the drive gear. A fixing ring is fixed on the moving rod, and a tension spring is provided between the fixing ring and the fixed cylinder.

[0015] The inner side of the web of the channel steel is provided with a movable groove for accommodating the locking teeth.

[0016] Furthermore, a steering self-locking structure is installed on the rotating rod;

[0017] The steering self-locking structure includes a ratchet coaxially mounted with the rotating rod. A "△" shaped swing block is provided on the side of the rotating rod. A pawl is provided on the upper end of the swing block near the ratchet. The lower end of the swing block near the ratchet is connected to the fixed plate by a pin. The lower end of the swing block away from the ratchet extends out of the ratchet.

[0018] Meanwhile, the upper end of the passive commutation drive structure extends to the roller.

[0019] Furthermore, a sunshade frame is installed above the canopy, and a sunshade net is installed on the surface of the sunshade frame.

[0020] Furthermore, the lower end of the crossbar extends into a pre-embedded ground anchor in the soil.

[0021] Furthermore, the side of the loading platform is provided with a sloping loading ramp, and rollers are evenly arranged on the sloping surface of the loading ramp.

[0022] Furthermore, the bidirectional lead screw slider is provided with double rails on both sides.

[0023] Furthermore, the outer side of the connecting rod is provided with anti-slip texture.

[0024] Furthermore, the cross-section of the movable rod is square.

[0025] Furthermore, a roller is installed on the side of the lower end of the swing block that extends out of the ratchet.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The cargo transport cableway of the present invention is connected between the saddle and the cargo basket by a quick-connect mechanism. The socket structure and plug structure in the quick-connect mechanism can quickly connect and disconnect when they arrive at the loading station and unloading station. The connection and disconnection of the socket structure and plug structure do not require external power. Therefore, the cableway does not need to be stopped during loading and unloading. This avoids the impact force generated by frequent start and stop, which can easily cause uneven stress and metal fatigue to the traction cable steel wire rope and other structures. It also improves the transportation progress of construction materials and ultimately speeds up the overall progress of power construction projects.

[0028] 2. The quick-connect mechanism of the present invention is equipped with a steering self-locking structure and a clamping self-locking structure, which allows the quick-connect mechanism to flexibly change its movement state during use. It can ensure that the position of the quick-connect mechanism is restricted during transportation by the steering self-locking structure and the clamping self-locking structure to prevent displacement that could cause goods to fall off or the socket structure and plug structure to fail to connect. It can also ensure that when the socket structure and plug structure need to be separated, the steering self-locking structure and the clamping self-locking structure can act quickly to temporarily release the restriction on the quick-connect mechanism.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0040] Example 1

[0041] Figure 1-7 As shown: A cargo transport cableway system for power construction includes a cargo tunnel. Cabins are evenly suspended on the track cable 2 in the cargo tunnel. Each cabin includes a saddle 3. The saddle 3 is connected to a cargo basket 7 via a quick-connect mechanism 4. Loading platforms 8 are set on the ground at both the loading station and the unloading station. A sloping loading ramp 12 is set on the side of the loading platform 8. Rollers are evenly arranged on the slope of the loading ramp 12 to facilitate pushing the cargo basket 7 onto the loading platform 8 along its slope.

[0042] The quick-connect mechanism 4 includes a plug structure and a socket structure.

[0043] The plug structure includes a traction rod 47 fixed vertically to the top of the cargo basket 7 and a connecting rod 46 fixed to the side of the traction rod 47.

[0044] The socket structure includes a fixed plate 42 installed at the end of the saddle 3. A rotating rod 41 is coaxially arranged on the fixed plate 42. The upper end of the rotating rod 41 passes through the fixed plate 42 and is coaxially arranged with a limit cap 43 for limiting its axial position. The lower end of the rotating rod 41 is connected to a mounting box 44. A drive gear 45 is arranged at the rear of the mounting box 44. A bidirectional lead screw 49 is coaxially arranged on the drive gear 45. The end of the bidirectional lead screw 49 away from the drive gear 45 extends into the mounting box 44. Bidirectional lead screw sliders 413 are installed on the threads of the bidirectional lead screw 49 with different directions of rotation. Double rails 412 are arranged on both sides of the bidirectional lead screw slider 413 to ensure its movement trajectory. Movable plates 48 are connected to the sides of the bidirectional lead screw slider 413. Similarly, in order to limit the movement trajectory of the movable plates 48, guide posts 410 are arranged between the movable plates 48. The two ends of the guide posts 410 pass through the movable plates 48 and are fixed to the inner wall of the mounting box 44. Semi-circular clamping plates 414 are installed on the opposite surfaces of the movable plates 48.

[0045] When the drive gear 45 rotates, it drives the bidirectional lead screw 49 to rotate, thereby causing the bidirectional lead screw slider 413 to move towards or away from each other. When the bidirectional lead screw slider 413 moves towards or away from each other, it causes the movable plates 48 connected to each other to move closer or further away. When they move closer, the clamping plate 414 clamps the connecting rod 46 in the plug structure between them. When they move further away, the connecting rod 46 between them is released, thereby realizing the rapid separation and combination of the plug structure and the socket structure, and finally realizing the rapid separation and combination of the cargo basket 7 and the saddle 3. In order to strengthen the fixation of the connecting rod 46, the outer side of the connecting rod 46 is provided with anti-slip texture.

[0046] In order to drive the drive gear 45 to rotate, a passive clamping drive structure 6 is provided at both the loading station and the unloading station along the running direction of the socket structure.

[0047] The passive clamping drive structure 6 includes a channel steel 61 with the same mounting height as the drive gear 45 and a bracket for fixing the channel steel 61. One of the wing plates of the channel steel 61 is provided with a pull-out rack that meshes with the drive gear 45. The pull-out rack is installed in opposite positions on the channel steel 61 at the loading station and the unloading station.

[0048] The cargo basket 7 with the plug structure is placed on the loading platform 8 of the loading station. When the traction machine 1 rotates, it drives the track cable 2 to rotate cyclically between the traction machines 1. When the socket structure moves with the track cable 2 to the loading station, the connecting rod 46 enters the mounting box 44 through the reserved insertion hole 411 on the mounting box 44 and is placed between the clamping plates 414. At this time, due to the obstruction of the traction rod 47, the socket structure that moves with the track cable 2 drives the cargo basket 7 to move with the saddle 3 on the loading platform 8 through the plug structure. At the same time, the drive gear 45 at the rear of the mounting box 44 enters the channel steel 61 and meshes with the insertion rack located on the lower wing plate. At this time, the drive gear 45 rotates clockwise and drives the bidirectional screw slider 413 to move towards each other through the bidirectional screw 49, so that the clamping plate 414 gradually approaches until it completes the clamping of the connecting rod 46. In this way, the cargo basket 7 loaded with goods is hung on the track cable 2 and moves together with it to the unloading station.

[0049] When the load is placed on the unloading station's loading platform 8, the drive gear 45 engages with the pull-out rack in the channel steel 61 of the unloading station. However, the pull-out rack in the channel steel 61 of the unloading station is mounted on the upper side wing plate of the channel steel 61. Therefore, when the drive gear 45 engages with the pull-out rack of the unloading station, the drive gear 45 rotates counterclockwise, which drives the bidirectional lead screw slider 413 to move in the opposite direction through the bidirectional lead screw 49, causing the clamping plate 414 to gradually separate and release the clamping of the connecting rod 46, thereby realizing the separation of the socket structure and the plug structure. After the two are separated, the cargo basket 7 falls onto the loading platform 8 of the unloading station.

[0050] However, when the cargo basket 7 carrying goods moves towards the unloading station, the connecting rod 46 is always located in front of the socket structure. This means that even after the clamping plate 414 separates, causing the plug structure and socket structure to separate, the socket structure will still push the traction rod 47 to move the cargo basket 7 due to the obstruction of the traction rod 47. Therefore, after the plug structure is fixed by the socket structure, the quick-connect mechanism 4 and the cargo basket 7 need to be rotated 180° so that the traction rod 47, which was previously located in front of the socket structure, can be rotated to the rear of the socket structure. This way, the separation of the plug structure and socket structure will not be obstructed when the cargo platform 8 reaches the unloading station.

[0051] Therefore, a double rail 412 is coaxially mounted on the rotating rod 41, and a passive reversing drive structure 5 is symmetrically mounted in front of the cargo platform 8 along the cableway running direction. The passive reversing drive structure 5 is also fixed by a bracket. A steering rack is provided on the side of the passive reversing drive structure 5 on one side of the bracket near the rotating rod 41. The steering rack is at the same height as the double rail 412, and the number of teeth of the steering rack is half the number of teeth of the double rail 412.

[0052] When the double rail 412 moves between the passive reversing drive structures 5, the double rail 412 meshes with the steering rack. Since the number of teeth of the steering rack is half the number of teeth of the double rail 412, the double rail 412 will only rotate by a normal number of teeth, i.e., 180°, after passing between the passive reversing drive structures 5. This completes the quick-connect mechanism 4 and the cargo basket 7 to complete a 180° rotation.

[0053] Therefore, when the cargo basket 7 is attached to the saddle 3 at the loading station, the quick-connect mechanism 4 and the cargo basket 7 are rotated 180° by the passive reversing drive structure 5 located in front of the loading station, so that the traction rod 47 is rotated to the rear of the socket structure, so that the plug structure and the socket structure will not be obstructed when the cargo platform 8 of the unloading station is reached.

[0054] After the cargo basket 7 and saddle 3 are separated at the unloading station, the socket structure needs to be reset so that the section with the socket 411 faces forward. Therefore, a passive reversing drive structure 5 is also set at the front and rear of the unloading station to rotate the socket structure 180° again to return to its original state.

[0055] The brackets used to fix the passive commutation drive structure 5 and the passive clamping drive structure 6 both include a vertically set upright and a cantilever at the top of the upright. The passive commutation drive structure 5 or the passive clamping drive structure 6 is installed at the end of the cantilever away from the upright.

[0056] Example 2

[0057] The difference between this embodiment and embodiment one is that after the connection between the socket structure and the plug structure in the quick-connect mechanism 4 is completed, in order to prevent the clamping plate 414 from loosening and causing the connecting rod 46 to fall off between the two, it is necessary to fix the drive gear 45 and restrict its circumferential movement.

[0058] Therefore, a clamping self-locking structure 10 is installed on the side of the drive gear 45, and a strong magnet 62 for triggering the clamping self-locking structure 10 is installed at the rear of the channel steel 61.

[0059] The clamping self-locking structure 10 includes a fixed cylinder 101 arranged parallel to the bidirectional lead screw 49. One end of the fixed cylinder 101 is fixed to the mounting box 44, and a moving rod 103 is inserted into the other end. A locking tooth 104 is fixed on the side of the moving rod 103 away from the fixed cylinder 101 and close to the drive gear 45. The locking tooth 104 extends between the teeth of the drive gear 45. A fixing ring is fixed on the moving rod 103, and a tension spring 102 is provided between the fixing ring and the fixed cylinder 101.

[0060] Under normal circumstances, one end of the locking tooth 104 is fixed to the moving rod 103, and the other end is locked between the teeth of the drive gear 45, thereby restricting the circumferential rotation of the drive gear 45. Since the drive gear 45 needs to rotate after entering the channel steel 61, a strong magnet 62 is installed at the rear of the channel steel 61. When the clamping self-locking structure 10 moves to the channel steel 61 with the socket structure, the strong magnet 62 pulls the moving rod 103 and the locking tooth 104 by magnetic force, pulling the locking tooth 104 out from between the teeth of the drive gear 45 and stretching the tension spring 102 so that it can rotate. At the same time, an active groove 63 for accommodating the locking tooth 104 is opened on the inner side of the web of the channel steel 61.

[0061] After passing between the channel steels 61, the magnetic force of the strong magnet 62 is lost. The stretched tension spring 102 pulls the fixed ring on the moving rod 103, causing the moving rod 103 and the locking tooth 104 to reset, so that the locking tooth 104 continues to engage between the teeth of the drive gear 45. At the same time, in order to prevent the moving rod 103 from circumferentially moving and causing the locking tooth 104 to swing, so that it cannot engage between the teeth of the drive gear 45, the cross section of the moving rod 103 is square.

[0062] Example 3

[0063] The difference between this embodiment and embodiment one is that after the quick-connect mechanism 4 and the cargo basket 7 complete a 180° rotation through the passive reversing drive structure 5, a steering self-locking structure 9 is installed on the rotating rod 41 to prevent the quick-connect mechanism 4 from continuing to rotate.

[0064] The steering self-locking structure 9 includes a ratchet 91 coaxially mounted with the rotating rod 41. A swing block 92 in the shape of a "△" is provided on the side of the rotating rod 41. A pawl is provided on the upper end of the swing block 92 near the ratchet 91. The lower end of the swing block 92 near the ratchet 91 is connected to the fixed plate 42 by a pin. A roller 93 is installed on the lower end of the swing block 92 away from the ratchet 91 after extending out of the ratchet 91.

[0065] Meanwhile, the upper end of the passive commutation drive structure 5 extends to the roller 93;

[0066] Under normal circumstances, the pawl on the swing block 92 is engaged between the teeth of the ratchet 91, restricting its circumferential rotation. When the double rail 412 moves between the passive reversing drive structure 5, the roller 93 located outside the ratchet 91 is squeezed by the passive reversing drive structure 5, causing it to swing around the pin axis outside the ratchet 91, so that the pawl is removed from between the teeth of the ratchet 91, allowing the ratchet 91 to rotate.
