Description

Technical Field

[0001] This utility model belongs to the field of passenger aerial ropeway rescue technology, specifically relating to a passenger ropeway horizontal rescue device, and more specifically to a passenger ropeway horizontal rescue device equipped with an eight-person detachment grip or a detachment grip for up to eight people. Background Technology

[0002] Currently, there are four main types of horizontal rescue methods for passenger ropeways in China: the first is the active-moving roller basket type; the second is the circulating rope traction driven-moving roller basket type; the third is the sliding type where the traction cable tows the traction cable and the vehicle after the grip is opened; and the fourth is the traction cable traction driven-moving roller reciprocating type. Each of these methods has its advantages and disadvantages, influenced by factors such as the slope of the route, terrain, ease of operation, construction economy, rescue efficiency, and potential damage to the ropeway system itself. The choice of rescue system type is determined based on different constraints.

[0003] Regarding the third type of cableway horizontal rescue method mentioned above, existing products require rescue personnel to carry rescue equipment and a traction rope, ride a simple trolley along the cableway to the vehicle being rescued, and manually install the rescue clamp, traction rope, and cable grip opening device. After installation, the cable grip is opened manually, and a winch located on the line pulls the traction rope, which in turn pulls the rescue clamp, dragging the cable grip and the vehicle along the cableway. This method requires rescue personnel to carry the rescue equipment, resulting in a heavy load; the installation of the rescue equipment lacks a fixed operating platform and is conducted at height, making operation difficult and highly dangerous; during the rescue dragging process, the weight of the cable grip, the vehicle, and the personnel is all applied to the contact surface between the cable grip jaws and the cable, resulting in significant weight and a long sliding distance. This sliding friction causes irreversible mechanical friction damage to both the cable grip and the cable, greatly shortening their service life and adversely affecting equipment operation safety.

The support frame 601 is fixedly connected to the pre-set bolt holes on the upper suspension rod 701 via the support frame bolts 602 and the seventh nut 603. The support frame 601 is equipped with a seat surface, a backrest, and a footrest. The footrest is symmetrically arranged on both sides and has two positions, front and back, to accommodate different operating postures and maintain body comfort and stability.

[0047] like Figure 6a , 6b As shown, the cable clamp 8 mainly includes a buffer spring 801, an upper clamping plate 802, a lower clamping plate 803, and a disc spring bolt assembly 804. The upper clamping plate 802 and lower clamping plate 803 are positioned opposite each other and secured by the disc spring bolt assembly 804, providing a continuous and stable clamping force to the traction cable. The sides of the upper clamping plate 802 and lower clamping plate 803 are connected to the buffer spring 801, which is used to mitigate impact on the horizontal rescue device during operation. Before using the horizontal rescue device, the traction cable passes through the space between the buffer spring 801 and the upper and lower clamping plates 802 and 803. A torque wrench is used to tighten the disc spring bolt assembly 804, ensuring the cable clamp 8 provides the required anti-slip force to the traction cable.

[0048] The cable clamp 8 and the traction cable are placed together in the inner frame of the traction cable bearing frame 104 of the frame 1, and two long pins from the connecting pin group 12 are inserted into the preset pin holes on the frame 1 to prevent the cable clamp 8 from coming out.

[0049] The nylon clamp 13 is installed inside the outer frame of the traction cable bearing frame 104. The upper clamp 1301 of the nylon clamp 13 is fixed with clamp bolts 1303 and tenth nuts 1304 (e.g., Figure 2b As shown, the lower clamp 1302 of the nylon clamp 13 is connected and fixed using a short pin from the connecting pin assembly 12. The nylon clamp 13 is used to protect the traction cable and prevent it from contacting the metal edges of the horizontal rescue device. The outer sides of the upper and lower clamps are flared to prevent the traction cable from bending to a small radius.

[0050] like Figure 7As shown, the lifting mechanism 4 is connected to the limiting baffle 107 of the frame 1 via the main shaft 408. It is used to limit the position of the rigging of the rescued vehicle and to lift the rigging and the rescued vehicle. It mainly includes a lifting hook 401, a swing arm 402, a first connecting plate 403, a second connecting plate 404, a control lever 405, an anti-detachment hook 406, a pin 407, a main shaft 408, a first shaft 409, a second shaft 410, a third shaft 411, a lifting iron 412, and a limiting bolt 413. Limit bolts 413 are installed on both side plates of the lifting hook 401 to adjust the lifting height of the cable gripper, ensuring a uniform gap between the transport cable, the cable gripper, and the lifting hook 401 when the cable gripper is open. A support iron 412 is welded onto the lifting hook 401. The bearing surface of the support iron 412 has a special profile, which ensures a uniform gap in the horizontal direction between the transport cable and the clamping surface of the cable gripper when the cable gripper is open. The swing arm 402 is connected to the first connecting plate 403 via a first shaft 409. The anti-detachment hook 406, the first connecting plate 403, and the second connecting plate 404 are connected by a second shaft 410. The second connecting plate 404 and the lifting hook 401 are connected by a third shaft 411. The main shaft 408 passes through the lifting hook 401, the swing arm 402, and the limiting baffles 107 on both sides of the frame 1, and installs the lifting hook 401 and the swing arm 402 between the two limiting baffles 107. The operating lever 405 is connected to the second connecting plate 404 by a thread. The pin 407 is installed on the lifting hook 401. After the components of the lifting mechanism 4 are connected, a four-bar linkage is formed, and each connecting joint can swing freely. When engaging the sling grip, the operator pulls the control lever 405, causing the second connecting plate 404 to fold the first connecting plate 403 inwards towards the four-bar linkage. When the second shaft 410 mates with the grooves on both sides of the lifting hook 401, the anti-detachment hook 406 is rotated and engaged with the pin 407. At this point, the four-bar linkage transforms into a stable triangular structure. The two sides of the lifting hook 401 confine the sling grip within, preventing it from slipping off the support 412 during equipment operation. To disengage, the operator first releases the anti-detachment hook 406 from the pin 407, then pushes the control lever 405, causing the second connecting plate 404 to move the first connecting plate 403 outwards towards the four-bar linkage, disengaging the triangular structure. Under its own weight, the lifting hook 401 rotates downwards around the main shaft 408, at which point the lifting hook 401 separates from the sling grip.

[0051] like Figure 2a , 2b and Figure 7As shown, the hydraulic system 5 mainly includes a hydraulic station 501, a pressure relief valve 502, a position valve 503, a lifting cylinder 504, a pressing cylinder 505, a pressure plate 506, a pressure relief valve bolt 507, a position valve bolt 508, a fifth nut 509, a pressing cylinder bolt 510, a sixth nut 511, an oil tank bolt 512, and connecting pipelines. The hydraulic station 501 includes a protective cover, an oil tank, a manual pump, an accumulator, and a pressure gauge. The hydraulic station 501 is connected to the pre-installed fixed seat on the far end of the support frame 601 in the operator's chair 6 using oil tank bolts 512; the pressure relief valve 502 is connected to the pre-installed fixed seat on the support frame 601 via pressure relief valve bolts 507; the position valve 503 is connected to the pre-installed fixed seat on the limit baffle 107 in the frame 1 via position valve bolts 508 and the fifth nut 509; the pressing cylinder 505 is connected to the pre-installed fixed seat on the load-bearing plate 103 in the frame 1 via pressing cylinder bolts 510 and the sixth nut 511. The fixed seat connection is provided. The end of the cylinder rod of the pressing cylinder 505 is equipped with a concave pressure plate 506. During the process of pressing down the operating rod of the cable grabber to open the cable grabber, it can remain centered and prevent slippage. The lifting cylinder 504 is connected to the reserved threaded hole on the lifting rod connecting seat 106 in the frame 1. The hydraulic pipeline is arranged and connected along the line of hydraulic station 501-pressure relief valve 502-position valve 503-lifting cylinder 504-pressing cylinder 505. Each cylinder is equipped with a return spring, which can make the cylinder rod of the hydraulic cylinder automatically return to its position after pressure relief.

[0052] When the horizontal rescue device reaches the location of the vehicle being rescued, the operator engages the lifting mechanism 4 with the sling grip. At this time, the anti-detachment hook 406 of the lifting mechanism 4 has triggered the position valve 503, opening the oil circuit. The operator operates the manual pump of the hydraulic station 501 to increase the pressure to 200 bar. During this process, the cylinder rods of the downward cylinder 505 and the lifting cylinder 504 extend simultaneously. The pressure plate 506 at the end of the cylinder rod of the downward cylinder 505 presses down the sling grip operating lever, and the sling grip jaws gradually open to their maximum opening degree, with... There is a 4-5mm gap on each side of the transport cable. After the cylinder rod of the lifting cylinder 504 extends, it pushes the stop block 414 on the first connecting plate 403 in the lifting mechanism 4, causing the entire lifting mechanism 4 to rotate around the main shaft 408. At this time, the lifting hook 401 gradually lifts the cable gripper until the top surface of the limit bolt 413 contacts the bottom surface of the main beam 101. This position ensures that there is a 4-5mm gap between the transport cable and the lifting hook 401 and the clamping surface of the opened cable gripper, so as to ensure that no friction damage occurs during subsequent travel. After the hydraulic pressure is established, the accumulator installed on the hydraulic station 501 maintains the pressure. When the rescue vehicle arrives at the designated rescue location, the operator opens the pressure relief valve 502 to release the pressure in the system. The cylinder rods of the pressing cylinder 505 and the lifting cylinder 504 retract under the tension of the return spring inside the cylinder. The hydraulic oil in the cylinder flows back to the oil tank from the hydraulic pipeline. At this time, the cable gripper tightens the transport cable again, and the vehicle is re-fixed to the transport cable.

[0053] like Figure 2a and 2b As shown, the stop block 9 is installed in the gap between the traction cable support frame 104 and the traveling roller 2 by the stop block bolt 901 to prevent the support cable from getting stuck in the gap after it comes off. The hook 10 and the safety belt hook ring 11 are respectively installed in the pre-set threaded holes on the main beam 101 in the frame 1 by bolts 1101, for hanging the rescue equipment and attaching the safety belt hook.

[0054] When rescuers ride in the horizontal rescue device, the device's own weight and the traction cable pull it back and forth along the transport cable. When the horizontal rescue device reaches the location of the vehicle being rescued, the flared shape of the balance wheel guide rail 105 on the frame 1 smoothly guides the balance wheel of the rigging device into the balance wheel guide rail 105, keeping the vehicle being rescued and the horizontal rescue device relatively fixed in their circular motion around the transport cable. At this point, by rotating the handwheel 301 of the manual walking drive device 3, the horizontal rescue device is aligned with the rigging of the vehicle being rescued. Operating the lever 405 of the lifting mechanism 4 causes the first connecting plate 403 and the second connecting plate 404 to fold inward into the four-bar linkage and abut against the lifting hook 401. At this point, the lifting hook 401 will loop under the rigging device from below, gripping the inner and outer clamps on both sides and supporting the lower edge of the inner and outer clamps. The anti-detachment hook 406 engages with the pin 407 to maintain this state. Simultaneously, the inclined surface on the anti-detachment hook 406 triggers the position valve 503 of the hydraulic system 5, opening the hydraulic circuit. The manual pump is then operated to continuously pressurize to 200 bar. During this process, the pressure plate 506 on the lowering cylinder 505 moves downward to contact the sling grip operating lever, overcoming the sling grip spring force and gradually opening the sling grip jaws until the lowering cylinder 505 reaches its full stroke of 156 mm, with the jaws opening by 8-10 mm. After the lifting cylinder 504 builds up pressure, the cylinder rod extends simultaneously, pushing the lifting mechanism 4 horizontally. The lifting mechanism 4 rotates upward around the main shaft 408, lifting the sling grip and the transport vehicle together to the preset position. At this time, the relative position of the lifting mechanism 4 and the traveling roller 2 ensures that the transport cable remains centered in the sling grip jaws, thus preventing frictional interference.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
