Description

Technical Field

[0001] The present invention relates to the technical field of monorail transportation, and in particular to an intelligent control system for a track conveyor. Background Art

[0002] Monorail transporters have significantly resolved the transportation challenges in hilly and mountainous areas, facilitating the transport of agricultural and sideline products in these challenging terrains. Monorail transporters are primarily fuel-powered and electric-powered. Because monorail transporters are highly seasonal, they are frequently used during harvest and often idle at other times. Long periods of inactivity can easily lead to battery drain and damage. Furthermore, monorail transporters are frequently used during operation, which hinders battery charging and prevents them from meeting the high-intensity transportation demands of the period. Therefore, current monorail transporters are primarily fuel-powered.

[0003] However, the current fuel-type monorail transporter has the following shortcomings:

[0004] 1. The parking and shifting of current fuel-powered monorail transport vehicles require manual operation. During use, the monorail transport vehicle needs to be equipped with many parking spaces to facilitate the loading and unloading of products. Manual parking and shifting require the operator to move with the vehicle. The operator sitting on the vehicle poses a safety hazard. The operator has to chase the vehicle on the ground, which is labor-intensive and the operation is unchanged. This greatly affects the transportation efficiency of the monorail transport vehicle and the use effect is not ideal.

[0005] 2. The carriages of current monorail transport vehicles do not have a braking function and rely solely on the braking of the front of the vehicle. The braking of the carriages is unstable and can easily cause braking shock, causing the transported items inside the carriage to be damaged;

[0006] 3. If the vehicle relies solely on the front brake and the drive shaft breaks due to overloaded transportation, all existing speed limit protection measures of the entire machine will be ineffective, and the consequences of the entire machine sliding will be very serious;

[0007] 4. The current monorail transport vehicle track change needs to be completed manually, which is affected by human movement, resulting in untimely track change and low track utilization, which cannot meet the track laying and use requirements in complex terrain. Summary of the Invention

[0089] The structure of the second rotary drive member is the same as that of the first rotary drive member, and the second rotary drive member and the first rotary drive member are symmetrically distributed about the width midline of the fixed seat 28. This arrangement can prevent the first connecting guide rail 31 from colliding with the second connecting guide rail 30, ensuring safe track change.

[0090] The first rotary driving member includes a first driving groove 3601 that passes through the outside of the first lifting tube 36 and a first driving column 4101 that is arranged on the outside of the first bearing column 41. The first driving column 4101 extends into the first driving groove 3601.

The inclined part extends obliquely toward the center of the fixed seat 28 on the outer surface of the first lifting tube 36. In this way, when the first supporting assembly 34 drives the first lifting tube 36 to rise and fall on the outside of the first bearing column 41, when the first driving column 4101 is in the first driving groove 360 1, the first supporting tube is lifted and lowered only on the outside of the first supporting column 41; when the first driving column 4101 is in the inclined portion of the first driving groove 3601, the first lifting tube 36 is lifted and lowered while rotating on the outside of the first supporting column 41; specifically, the first supporting assembly 34 drives the first lifting tube 36 to descend, and at this time the first driving column 4101 gradually enters the inclined portion from the vertical portion of the first driving groove 3601. Since the inclined portion extends obliquely toward the center of the fixing seat 28 on the outer circumference of the first lifting tube 36, the first driving column 4101 contacts the inner wall of the inclined portion. Under the action of the reaction force, the first lifting tube 36 moves away The first connecting guide rail 31 is rotated in the direction away from the width center line of the fixed seat 28, thereby driving the first connecting guide rail 31 away from the width center line of the fixed seat 28, realizing the separation of the guide rails; the first supporting assembly 34 drives the first lifting tube 36 to rise, and the first driving column 4101 contacts the inner wall of the inclined portion, causing the first lifting tube 36 to rotate toward the width center line of the fixed seat 28. When the first driving column 4101 is at the connection between the inclined portion and the vertical portion, the first connecting guide rail 31 is just above the connection line between the main guide rail 29 and the first branch guide rail 40.

At the same time, the movement state of the first lifting tube 36 is accurate and stable, which can ensure the accuracy of the separation and docking of the guide rails, thereby improving the accuracy of the track change and ensuring the safety of the track change;

[0091] The first supporting assembly 34 has the same structure as the second supporting assembly 35. The first supporting assembly 34 includes a track-changing electric telescopic rod 3401 and a lifting ring 3402. The lifting ring 3402 is slidably arranged on the outside of the first supporting column 41.

The output end of the track-changing electric telescopic rod 3401 is connected to the lifting ring 3402. In this arrangement, the lifting ring 3402 is driven to rise by the track-changing electric telescopic rod 3401, so that the lifting ring 3402 supports the first lifting tube 36 to rise; the track-changing electric telescopic rod 3401 drives the lifting ring 3402 to descend, and the first lifting tube 36 descends under the action of gravity;

[0092] A guide plate 3403 is provided at the bottom of the lifting ring 3402. A limiting groove 3404 is provided on the outer side of the guide plate 3403.

[0093] Among them, the bottom of the first supporting column 41 and the second supporting column 43 are connected to the fixing seat 28 with a reinforcing rib 44. This arrangement can strengthen the strength of the first supporting column 41 and the second supporting column 43, which helps to improve safety;

[0094] The first connecting guide rail 31 and the second connecting guide rail 30 are both arc-shaped structures, and the two are symmetrically distributed with the width midline of the fixing seat 28 as the reference. This arrangement can ensure the docking accuracy of the first connecting guide rail 31 and the second connecting guide rail 30;

[0095] The ends of the main guide rail 29, the first branch guide rail 40 and the second branch guide rail 42 near the center of the fixed seat 28 are all provided with slots 38, and the slots 38 are sunken grooves. Both ends of the first connecting guide rail 31 and the second connecting guide rail 30 are provided with plug blocks 39, and the plug blocks 39 are plugged into the slots 38. In this way, the plug blocks 39 and the slots 38 can improve the docking accuracy of the first connecting guide rail 31 and the second connecting guide rail 30, and at the same time, can improve the strength of the first connecting guide rail 31 and the second connecting guide rail 30 after docking, thereby ensuring the safety of the vehicle head when passing.

[0096] With the above structure, the controller can cooperate with the G network version mobile phone applet or infrared remote control for remote control operation; when parking is required, the parking electric telescopic rod 13 drives the parking lower rocker arm 17 to rotate toward the parking push rod 15 of the front body 1. During the rotation process, the parking lower rocker arm 17 releases the pull on the throttle cable 14 of the front body 1. The throttle cable 14 relaxes and the engine of the front body 1 stops. At the same time, the parking lower rocker arm 17 pushes the parking push rod 15, so that the brake structure of the front body 1 is activated, thereby achieving parking of the front body 1;

[0097] When the vehicle body 1 needs to move, the parking electric telescopic rod 13 drives the parking lower rocker arm 17 to rotate in a direction away from the parking push rod 15, and the parking lower rocker arm 17 releases the push on the parking push rod 15, releasing the brake, and the parking lower rocker arm 17 rotates to pull the throttle cable 14, so that the vehicle body 1 can move;

[0098] When the driving direction of the vehicle body 1 needs to be changed, the parking assembly is first used to put the vehicle body 1 in the parking state, and the electric telescopic shift rod 6 drives the shift block 8 to rotate through the elastic telescopic rod 7, and the shift block 8 drives the shift lever of the vehicle body 1 to switch between the forward gear and the reverse gear of the vehicle body 1, thereby realizing the change of the driving direction of the vehicle body 1. After the change is completed, the parking state is released and the vehicle body 1 starts to move;

[0099] During the gear shifting process, when the transmission gear inside the gearbox of the front body 1 has a tooth-top phenomenon, the shift paddle block 8 will not rotate under the action of the tooth-top phenomenon. At this time, the elastic telescopic rod 7 is deformed by force. Specifically: after the tooth-top phenomenon occurs during the process of the electric telescopic rod 6 and the elastic telescopic rod 7 pulling the shift paddle block 8, the elastic telescopic rod 7 is stretched by the tension, and the trigger rod 11 moves along with the telescopic inner end of the elastic telescopic rod 7 and contacts the lower contact switch 10, indicating that the tooth-top phenomenon occurs; after the tooth-top phenomenon occurs during the process of the electric telescopic rod 6 and the elastic telescopic rod 7 pushing the shift paddle block 8, the elastic telescopic rod 7 is subjected to pressure, and the trigger rod 11 moves along with the telescopic inner end of the elastic telescopic rod 7 and contacts the upper contact switch 12, indicating that the tooth-top phenomenon occurs;

[0100] When the tooth-jump phenomenon occurs, the low-speed drive assembly 16 drives the input shaft of the gearbox of the vehicle head body 1 to rotate at a low speed, so that the transmission gears inside the gearbox are accurately engaged and the tooth-jump phenomenon is eliminated. At this time, the elastic telescopic rod 7 is no longer under force, thereby driving the shift paddle 8 to rotate, realizing automatic shifting. The device can realize remote control for automatic parking and automatic shifting, which can meet the parking requirements of different positions without the need for the operator to move with the vehicle, and has good use effect and good flexibility.

[0101] The traveling assembly 24 cooperates with the guide rail to enable the carriage 2 to travel on the track under the traction of the locomotive body 1. During the driving process, the speed measuring assembly detects the rotation speed of the traveling main shaft 2401 of the traveling assembly 24, and the speed measuring assembly transmits the rotation speed detection signal to the controller. When the rotation speed of the traveling main shaft 2401 exceeds the set safe speed range, the controller controls the braking assembly 25 to operate, and brakes the traveling main shaft 2401 by means of friction braking, so that the rotation speed of the traveling main shaft 2401 is within the set safe speed range, and the driving safety is high; the braking assembly 25 performs friction braking on the traveling main shaft 2401, thereby realizing independent braking of the carriage 2, and cooperating with the braking of the locomotive body 1 can make the braking of the carriage 2 stable, reduce the impulse of the carriage 2 when braking, thereby protecting the products transported inside the carriage 2, and the use effect is good; when the locomotive axle is broken due to load problems, the controller controls the braking assembly 25 to operate, and brakes the traveling main shaft 2401 by means of friction braking, thereby braking the entire vehicle, and playing the role of axle breakage protection;

[0102] When the track needs to be changed, the first rotating drive member drives the first lifting tube 36 to rotate in the direction that the first connecting guide rail 31 is located above the connecting line of the main guide rail 29 and the first branch guide rail 40, and the first supporting assembly 34 contracts. Under the action of gravity, the first lifting tube 36 descends on the outside of the first supporting column 41, so that the first connecting guide rail 31 descends to between the main guide rail 29 and the first branch guide rail 40, and the two ends of the first connecting guide rail 31 are connected with the main guide rail 29 and the first branch guide rail 40; when the track is separated, the first supporting assembly 34 supports the first lifting tube 36 to rise on the outside of the first supporting column 41. After the first connecting guide rail 31 is separated from the main guide rail 29 and the first connecting guide rail 31, the first rotating drive member drives the first lifting tube 36 to rotate so that the first connecting guide rail 31 is away from the width center line of the fixed seat 28, thereby realizing the separation of the first connecting guide rail 31 from the main guide rail 29 and the first branch guide rail 40; with the same principle as above, through the second supporting assembly 35 and the second rotating drive member The second connecting guide rail 30 is connected to the main guide rail 29 and the second branch guide rail 42 by means of the control box 32. In the specific use process, the control box 32 is used to control the working states of the first supporting assembly 34 and the first rotating driving member and the second supporting assembly 35 and the second rotating driving member to be completely opposite, so that the second connecting guide rail 30 gradually connects with the main guide rail 29 and the second branch guide rail 42 during the separation of the first connecting guide rail 31 from the main guide rail 29 and the first branch guide rail 40, or the first connecting guide rail 31 gradually connects with the main guide rail 29 and the first branch guide rail 40 during the separation of the second connecting guide rail 30 from the main guide rail 29 and the second branch guide rail 42, thereby realizing automatic track changing, without the need for track changing personnel to move between multiple track branches, which greatly reduces the labor intensity of track changing personnel; timely track changing helps to improve transportation efficiency and track utilization, and has good use effect;

[0103] In the early stage of transportation, the positions of the first trigger cam 405 and the second trigger cam 406 are adjusted according to the route that the front body 1 needs to travel. Specifically, the locking nut 404 is loosened to make the first trigger cam 405 and the second trigger cam 406 active, the first trigger cam 405 is rotated to make its convex point downward, and the second trigger cam 406 is rotated to make its convex point upward. During the travel of the front body 1, the first trigger cam 405 will trigger the first main rail contact switch 401 or the first branch rail contact switch 407. After receiving the signal, the control box 32 performs the track change operation to make the first connecting guide rail 31 dock with the main rail 29 and the first branch guide rail 40, thereby realizing automatic track change; similarly, the convex point of the second trigger cam 406 is made downward, and the convex point of the first trigger cam 405 is made upward. During the travel of the front body 1, the second trigger cam 406 will trigger the second main rail contact switch 402 or the second branch rail contact switch 408, thereby making the second connecting guide rail 30 dock with the main rail 29 and the second branch guide rail 42, thereby realizing automatic track change;

[0104] Automatic track changing can be achieved through the intelligent track changing system 3, so that corresponding track layout can be carried out according to the specific application environment, which can meet the simultaneous travel of multiple locomotive bodies 1 and perform automatic track changing to ensure the smooth and safe travel of multiple locomotive bodies 1, greatly improving the track utilization rate and improving transportation efficiency.
