Problems solved by technology

However, a series of overall costs such as track laying in the early stage of application, establishment of power and monitoring systems, and maintenance and replacement in the later stage are too high, so it is not suitable for some occasions with low requirements for use.

Embodiment 1

[0060] Such as figure 1 , 3 As shown in 4, the trackless cable conveyor of this embodiment includes active sling towers 1-A, driven sling towers 1-B and 1-C, which are set on three mountain tops, and drive stepping motors 2-A, 2 -B and 2-C, the cable retractable assembly includes a reducer 22, a drum 21; three-wheeled pulley block 3-A, 3-B, 3-C, three steel cables 4, connected to the turntable 5, and DC gear motor 6, One end of the steel cable 4 is fixed to the drums installed on the active sling tower and the two driven sling towers, and the other end is fixed to the connecting turntable (ie, control point S). Three sets of driving stepper motors The speed control of the three cables affects the low-altitude suspension transportation of the suspension box 8. A tension sensor 15 is arranged between the suspension box 8 and the DC reduction motor 6, and the signal of the tension sensor is input to the transistor alarm circuit 16 inside the suspension box 8 as a trigger signal. ...

Embodiment 2

[0069] Such as Figure 2a with 2b , The horizontal distance between the two active sling tower point A and the driven sling tower point B at the top of the mountain is set to 320m; the height of the fruit mountain is between 200 and 350, and the height difference between adjacent fruit mountains is in the range of Δh Between 10m and 50m, we set the mountain height to 240m; the fruit mountain slope is between 30°~45°, and we set the inclination angle of the suspension box 8 downhill transportation route to 36.87° The transportation process is: a suspension box filled with picked fruits (total mass 100kg) is placed on the active sling tower point A on the top of the mountain, and hooks at the end of the ropes are hung, and two or three cables are connected to each hook. The other end of each cable is connected to a reel, and the reel is externally driven by a stepping motor and a reducer. Therefore, each cable is driven by a separate stepping motor to control the traction speed, ...

Embodiment 3

[0081] Contains one active sling tower point A and two driven sling tower points B and C. The working area is a triangular area surrounded by three points. We set the horizontal distance between the active sling tower point A and the driven sling tower point B, and the active sling tower point A and the driven sling tower point C to 320m; the height of the fruit mountain is between 200 and 350. The range of height difference Δh between adjacent fruit mountains is between 10m and 50m. We set the height of the mountain to 240m; the slope of Guoshan is between 30°~45°, and we set the inclination of the downhill transportation route to 36.87°

[0082] Even so, the suspension box transportation route model of Guoshan where each sling tower is located is the same as the two-dimensional model, which is approximated by a straight line to build the model. Of course, the triangular area may only contain the fruit mountain where the three sling tower points are located, or it may contain a...

Abstract

The invention relates to a control system and a control method of a trackless cable conveyor, belonging to a mountain orchard material transportation control system. The control system of a conveyor comprises a main controller, a step driver, a rotational speed transmitter and a lifting controller. The lifting controller controls a fruit basket to be suspended at the starting point of the mountaintop, triggers the main controller to send a signal to the motor stepping driver so that the cable speed is further regulated, and transports the fruit basket downhill according to the set trajectory.If loading and unloading are required temporarily during transportation, the main controller distinguishes the ridges according to the manual triggering signal at the ridges, calls the interruption program corresponding to the ridges, and performs temporary positioning hovering work. The hovering state triggers the lifting controller to perform the basket lowering operation. After the worker finishes loading and unloading, the button triggers the lift controller to execute the reset operation, the reset state triggers the end of the interrupt program, and the main controller continues to execute the main program to control the low-altitude transportation. The whole system is efficient and low cost.

Description

Technical field [0001] The invention relates to a control system for a trackless cable conveyor and a control method thereof. Background technique [0002] In general, the design of mountain orchard transporters is mostly based on rail transport vehicles, including single-track and double-track. In this type of design, the transport aircraft has an independent traction system, positioning system, and even obstacle avoidance system, which can meet the application requirements of most occasions. However, the overall cost of the track laying in the early stage, the establishment of power and monitoring systems, and the maintenance and replacement in the later stage are too high, and it is not suitable for some occasions with lower requirements. Summary of the invention [0003] The purpose of the present invention is: in view of the above-mentioned problems, one of the objects of the present invention is to provide a control system for a non-cabinet-rail type rope conveyor, which co...
