Description

Intelligent cableway trolley

Technical Field

The invention belongs to cableway transport machinery, and particularly relates to a cableway trolley which is controlled by a radio remote controller and can be hoisted and transported by a single cable system.

Background

The cableway is a mechanical device which takes a tensioned and suspended steel rope as a running track. The cableway transportation has the advantages that: the adaptability to the terrain is strong, and the mountain stream river deep groove steep slope of the mountain canyon can be transported by cableways; the ground surface damage of a road repairing team is not required to be small, and the short-cut transportation can be realized; the energy conservation and environmental protection are met, and the soil and water conservation is facilitated; compared with manpower transportation and road transportation, the method can be less affected by seasonal weather (such as natural weather of rain, fog, ice and snow lamps), and the construction and maintenance cost of roads is saved;

the func-tion of the cableway trolley, i.e. the trolley, as a function-executing mechanism of the cableway, determines the func-tion and efficiency of the cableway. In the process of implementing the technical scheme of the invention in the embodiment of the present application, the inventor of the present application finds that several existing cableway trolleys (i.e. sports cars) have at least the following technical problems:

the cableway sports car of the common traditional transport cableway can only be used for pure transportation and does not have the capability of independently hoisting or loading and unloading goods. The loading and unloading of goods on such ropeways require manpower or other external forces, and the loading and unloading of goods can be mostly carried out only at two fixed points, and the goods cannot be loaded or unloaded at most other places on the whole ropeway. The cableway transportation mode is called point-to-point transportation, and the mode has single function, low efficiency and narrow application range.

The cableway roadster of the cable crane reinforcement type cableway has the advantages of simple structure, few faults, reliable work and capability of hoisting and automatically loading and unloading goods. However, the ropeway cable system required by the sports car is complex, a multi-drum winch is required, the consumption of the steel cable is large, and the structure of the winch is complex. The cable system of the cable crane reinforcement type cableway is generally a bearing cable, a separate hoisting cable and an open or closed traction cable. If the hook falling of the ropeway carriage is difficult, a separate return cable is required. The required winch is generally a double-drum winch or even a three-drum winch, the winch is complex in structure and heavy in weight, the cableway is assembled and disassembled, and the transfer is troublesome and laborious, so that the cableway is not beneficial to popularization and practicability.

The cableway for the open traction hoisting (KJ3 cableway) needs special treatment on a bearing cable and a hoisting cable, a single stopper is fixed at a proper position of the bearing cable, a thick return tie is inserted at a proper position of the hoisting cable, and a stopper is arranged on a matched sports car to be matched with the stopper on the bearing cable and the return tie on the hoisting cable so as to realize the stopping positioning and the stopping releasing positioning of the sports car. The working process of the ropeway sports car is as follows: when the sports car runs to the position for fixing the retainer on the bearing cable, the retainer on the sports car is connected with the retainer fixed on the bearing cable to be positioned in a stopping mode, then the winch pulls the traction cable, the empty-returning knot on the traction cable is used for driving the hoisting cable buckling mechanism in the sports car to loosen the buckle, then the hoisting cable and the lifting hook can fall down, the lifting hook is hung on the goods winch to wind the hoisting cable, the empty-returning knot on the hoisting cable passes through the one-way opening buckling mechanism, and the thick empty-returning knot is blocked by the buckle, so that the goods cannot fall down. Meanwhile, a transmission lever of the buckle mechanism jacks a hook of the sports car stopper, so that the sports car stopper and the stopper on the bearing cable are separated and released from positioning. The tramcar for the cableway needs to be stopped and positioned by means of the stoppers which are respectively arranged on the tramcar and the carrying cable, the stoppers on the carrying cable are difficult to transfer to other positions, the tramcar can only carry out hoisting and descending operations at the fixed positions of the stoppers, and the tramcar cannot be stopped and positioned at other positions of the carrying cable. The ropeway sports car has a complex mechanical structure and low reliability, and spurious actions sometimes occur. If the catcher hook of the sports car is difficult to be combined with the stopper of the bearing cable, the catch mechanism of the empty knot can be loosened sometimes.

The remote controlled cableway with closed cable traction and hoisting type cableway (YP2.5A) is characterized by that the traction cable is inserted into a complete ring whose two ends are connected, the winch machine and sports car are respectively equipped with a friction reel, the ring traction cable can be successively wound on the friction reels of winch machine and sports car for several turns, the friction reels on the sports car and hoisting reels are connected after the speed reduction by means of driving gear, and an independent hoisting cable is wound on the hoisting reels, and the hoisting reels can be used for paying off and winding up the hoisting cable to implement the hoisting operation of goods. The sports car is provided with a remote control brake system, and can perform linkage interlocking braking on the bearing cable and the friction drum of the sports car. When the sports car is lifted, the remote control braking system clamps the bearing cable to brake and position the sports car. And simultaneously, the friction drum of the sports car is released from the linkage interlocking braking state with the bearing cable (the friction drum of the sports car is released when the bearing cable is clamped, and the friction drum of the sports car is clamped when the bearing cable is released). The winch drives the circulating traction cable and drives the friction winding drum to rotate, the further friction winding drum drives the hoisting winding drum to rotate through the speed reduction transmission mechanism, and the hoisting cable is wound to perform hoisting operation. After the hoisting is finished, the remote control stopping system brakes the friction drum of the sports car, simultaneously releases the braking of the bearing cable, and releases the braking positioning of the sports car on the bearing cable. The winch drives the circulating traction cable to pull the sports car and the lifted goods to move to the unloading site. The remote control brake system clamps the bearing cable to brake and position the sports car, and simultaneously releases the friction drum of the sports car. The winch controls the traction cable to be released to drive the friction drum of the sports car, and further drives the hoisting drum and the hoisting cable, and the hoisting hook and the goods descend to the ground. After the goods are unloaded, the lifting hook is retracted to a proper height. The remote control brake system releases the clamped bearing cable to the friction drum brake colleagues of the sports car. And (4) starting the winch to pull the sports car to the next working site, namely completing a complete working cycle. The ropeway sports car is heavy and complex in structure. The weight of the sports car reaches 450 kg, the traction cable needs to be inserted into two connected circulating cables in advance, the adaptability of the circulating traction cable to ropeways with different lengths is not strong, the insertion and tensioning of the circulating traction cable are troublesome and labor-consuming, and the loss of the steel wire rope is large. The linkage interlocking brake mechanism controlled by remote control has a brake gap, the carrier cable and the traction cable driven by the friction drum of the sports car are in a loosened state at the same time, the lifted goods can cause the sports car to move on a cableway under the action of the reaction force of gravity, and meanwhile, the goods have a falling trend, which is not beneficial to the stability and the safety of lifting.
