Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly to a multi-ring combined braking device for a mountain track transport vehicle. Background Art

[0002] An orchard distributed in hilly and mountainous terrains is called a mountain orchard. Due to its rugged mountain roads and complex terrain, conventional orchard transport vehicles are difficult to be effectively utilized, which greatly restricts the development of large-scale and integrated fruit industries. Fruits produced in mountain orchards have long relied on manual transportation, and a large amount of fruits are wasted because they cannot be effectively transported out. Some fruit farmers can only let the fruits rot in the orchard. Therefore, an orchard transport vehicle suitable for mountain and hilly terrains is of great importance for reducing the production cost of fruits, improving the efficiency of the fruit industry, and building a modern orchard. Due to the steep, complex, and large-gradient mountainous and hilly terrains, it is difficult to brake a mountain track transport vehicle under heavy load conditions, and it is difficult to fix the braking distance, with high potential safety hazards, which affects the driving safety of the transport vehicle. Summary of the Invention

[0034] In the embodiments of the present invention, as Figure 1 、 Figure 2 、 Figure 3 shown, a multi-ring combined braking device for a mountain track transporter includes:

[0035] Track 1;

[0036] Specifically, for the track, it includes two tracks, one is a driving track and the other is an auxiliary track. The driving track is convenient for the control assembly 2 to drive the transport mechanism 3 to move, and the auxiliary track is used to ensure the transport direction.

[0037] The transport mechanism 3 is slidably disposed on the track 1. The transport mechanism 3 includes a frame body 31, a bottom plate 32 fixed to the bottom of the frame body 31, and a traction rod 310 fixed to one side of the bottom plate 32;

[0038] Specifically, the transport mechanism 3 is used to load items and run on the track 1 under the drive of the traction rod 310.

[0039] The first braking mechanism 4 is provided at the bottom of the base plate 32. The first braking mechanism 4 includes friction blocks 43 symmetrically arranged on both sides of the track 1, a caliper 42 provided on one side of the friction block 43, and a return spring 41 connected between the two calipers 42;

[0040] Specifically, the first braking mechanism 4 is a mechanical braking mechanism. The hydraulic cylinder in the control assembly 2 drives the piston to move, thereby controlling the caliper 42 to drive the friction block 43 to move to achieve mechanical braking. The return spring 41 is used to reset the friction block 43;

[0041] The second braking mechanism 5 is provided at the bottom of the base plate 32. The second braking mechanism 5 is provided on one side of the first braking mechanism 4. The second braking mechanism 5 includes a fixed frame 51 and a magnetic track 53 provided at the bottom of the fixed frame 51. The magnetic tracks 53 are symmetrically arranged on both sides of the track 1. At the same time, it should be noted that a return spring 41 is also provided in the caliper 42, which is used to reset the friction block 43;

[0042] Specifically, the second braking mechanism 5 is a magnetic track braking mechanism. The three-phase asynchronous motor in the control assembly 2 drives the magnetic track 53 to move to achieve the magnetic track braking process.

[0043] The control assembly 2 is provided on one side of the transportation mechanism 3. The control assembly 2 is connected to the transportation mechanism 3 through the towing rod 310. The control assembly 2 includes a hydraulic cylinder, a three-phase asynchronous motor, a controller, and a sensor assembly that are electrically connected to each other. The control assembly is used to control the two friction blocks 43 to move towards the track 1 when the sensor assembly detects that it is in the normal braking mode, and to control the two magnetic tracks 53 to move towards the track 1 when the sensor assembly detects that it is in the emergency braking mode;

[0044] Specifically, the control assembly 2 is used to drive the entire transportation mechanism 3 to run through the towing rod 310. The control assembly includes a hydraulic cylinder, a three-phase asynchronous motor, a controller, and a sensor assembly. The hydraulic cylinder is used to drive the first braking mechanism 4, and the three-phase asynchronous motor is used to drive the second braking mechanism 5;

[0045] When in the normal braking mode, an electrical signal is transmitted to the controller through the sensor assembly. The control assembly 2 controls the hydraulic cylinder and the piston to adjust the required braking force according to different speeds, different gradients, and different loads and transmits it to the first braking mechanism 4 to lock the track 1, achieving a fixed braking distance;

[0046] When in the emergency braking mode, when the speed detected by the sensor assembly reaches the preset peak value, the control assembly 2 activates the three-phase asynchronous motor and controls the magnetic track 53 to move to lock the track 1.

[0047] On one side, an anti-lock braking track 1 is provided to prevent the transport mechanism 3 from tipping over. Then, the braking force can be adjusted by the first braking mechanism 4 and the second braking mechanism 5 under different gravities and different slopes, so that the braking distance can be adjusted. Thus, the control effect is achieved, manual braking is not required, the safety of manual operation is reduced, the braking efficiency is improved, and the potential safety hazards caused by manual braking can be reduced;

[0048] The driving force component of the transport mechanism 3 will produce additional acceleration or deceleration effects. When going uphill, the transport mechanism 3 requires a greater braking force to offset the gravity component; when going downhill, the transport mechanism 3 requires a greater braking force to prevent excessive speed. The load of the transport mechanism 3 directly affects its inertia. The greater the load, the greater the inertia of the vehicle and the greater the required braking force. Therefore, an electrical signal is transmitted to the controller through the sensor assembly. The control assembly 2 controls the hydraulic cylinder or the three-phase asynchronous motor according to different speeds, different slopes, and different loads to adjust the required braking force and transmit it to the first braking mechanism 4, the second braking mechanism 5, and the anti-lock track 1.

[0049] Therefore, in the conventional braking mode, the control assembly 2 drives the hydraulic cylinder to pressurize and then controls the movement of the friction block 43 to lock the track. In the emergency braking mode, the control assembly 2 drives the three-phase asynchronous motor to control the movement of the magnetic track 53 to lock the track. When the mountain track transporter is transporting, under the action of the sensor assembly, signals are output under different gravities, different slopes, and different speeds, driving the hydraulic cylinder to output corresponding pressures, realizing the locking of the track by the friction block 43 or the magnetic track 53. And in the case of different gravities, different slopes, and different speeds, the output signals of the sensor assembly are different, and the braking mode is identified according to the output signals and the corresponding track locking method is selected, so as to achieve a fixed braking distance and adjustable braking force. The present invention links mechanical braking and emergency braking, reduces safety problems, improves the braking efficiency, and can reduce the potential safety hazards caused by the overturning of the transport vehicle.

[0050] In this embodiment, a plurality of spaced-apart track brackets 6 are fixed to the bottom of the track 1;

[0051] Specifically, the track bracket 6 is specifically used to support the entire track 1.

[0052] In this embodiment, a limit plate 7 is fixed to one end of the track 1, and a buffer spring 8 is fixed to the side of the limit plate 7 facing the transport mechanism 3;

[0053] Specifically, the limit plate 7 is used to limit the transport mechanism 3, and at the same time, cooperate with the buffer spring 8 to buffer the transport mechanism 3.

[0054] In this embodiment, a first connecting plate 33 is fixed to the bottom of the bottom plate 32. A traveling wheel 36 is movably arranged below the first connecting plate 33. The traveling wheel 36 is arranged in cooperation with the track 1.

[0055] Specifically, the traveling wheel 36 is used to control the movement of the transport mechanism 3 and can also limit its movement direction.

[0056] In this embodiment, two side plates 34 are symmetrically fixed below the first connecting plate 33. A side wheel 35 is movably arranged on one side of the two side plates 34 close to each other. The side wheels 35 are symmetrically arranged on both sides of the track 1.

[0057] Specifically, the side wheels 35 are in contact with both sides of the track 1. The transport mechanism 3 can be further limited by the two side wheels 35 to ensure its operation along the track direction.

[0058] In this embodiment, a second connecting plate 37 is fixed below the bottom plate 32. An auxiliary wheel 38 is movably arranged on the second connecting plate 37. The auxiliary wheel 38 is arranged in cooperation with the track 1.

[0059] Specifically, the auxiliary wheel 38 is used to assist the movement of the transport mechanism 3 and ensure its balance.

[0060] In this embodiment, the first braking mechanism 4 includes a U-shaped plate 39. A caliper 42 is fixed on the U-shaped plate 39. A gasket 46 is fixed on one side of the caliper 42 close to each other. The gasket 46 is connected to a steel back plate 47 through an adhesive 44. A pull rod 45 is movably penetrated through the caliper 42 and the steel back plate 47.

[0061] Specifically, the above structure constitutes the first braking mechanism 4. The friction block 43 can be driven by the caliper 42. The gasket 46, the pull rod 45, and the steel back plate 47 are used to improve the stability of the entire first braking mechanism 4.

[0062] In this embodiment, a right-angle plate 52 is fixed to the bottom of the fixing frame 51. A magnetic track 53 is movably arranged on the right-angle plate 52.

[0063] Specifically, the right-angle plate 52 is used to improve the stability of the entire second braking mechanism 5.

[0064] In this embodiment, the sensor assembly includes a slope sensor, a gravity sensor, and a speed sensor.

[0065] Specifically, the above three sensors are respectively used to monitor the slope, gravity, and speed. According to Newton's second law, the braking force F = ma. The slope sensor, the gravity sensor, and the speed sensor measure the slope angle θ, the load M of the load platform, and the acceleration a. Using the formula F 1Calculate the ramp force using = mgsin(θ), and calculate the basic braking force using Newton's second law F 2 = ma. The total braking force = ramp force + basic braking force. According to the formula v 2 2 - v 0 2 = 2as, calculate the braking distance to achieve a constant braking distance.

[0066] In summary, for the multi - loop combined braking device of the mountain track transporter provided in this embodiment, in the normal braking mode, the control assembly 2 drives the hydraulic cylinder to pressurize and then controls the movement of the friction block 43 to lock the track. In the emergency braking mode, the control assembly 2 drives the three - phase asynchronous motor to control the movement of the magnetic track 53 to lock the track. When the mountain track transporter is in operation, under the action of the sensor assembly, signals are output at different gravities, different slopes, and different speeds, driving the hydraulic cylinder to output corresponding pressures to achieve the locking of the track by the friction block 43 or the magnetic track 53. Moreover, the output signals of the sensor assembly are different under different gravities, different slopes, and different speeds, and the braking mode is identified according to the output signals and the corresponding track - locking method is selected, thereby achieving a fixed braking distance and adjustable braking force. The present invention links mechanical braking and emergency braking, reduces safety problems, improves the braking efficiency, and can reduce the safety hazards caused by the overturning of the transporter.
