Detailed Description
The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
A schematic structural view of a first embodiment of the conveyor belt device of the present utility model is shown in fig. 1 to 2.
A conveyor belt device comprising a conveyor belt 2 frame 1 and a conveyor belt 2; at least two driving wheels 31 are arranged on the frame 1, the driving wheels 31 are respectively driven by a motor 32, and the driving wheels 31 and the motor 32 are in transmission connection through a unidirectional driving mechanism; the driving wheel 31 is in transmission connection with the conveyor belt 2 and drives the conveyor belt 2 to move.
In this embodiment, the number of the driving wheels 31 and the driven wheels 33 is 3, respectively, and the driving wheels 31 and the driven wheels 33 are arranged at intervals, and the outer diameters of the driving wheels 31 and the driven wheels 33 are the same.
The 3 motors 32 in the conveyor belt device are arranged on the frame 1, respectively drive the 3 driving wheels 31 to rotate and drive the conveyor belt 2 to move, and as shown in the figure, the conveyor belt device also comprises 3 driven wheels 33, the length of the whole device can be set to be more than 15 meters, and the material conveying with a very long distance is realized.
In the present embodiment, a unidirectional transmission mechanism is arranged between the motor 32 and the driving wheel 31, wherein the unidirectional transmission mechanism has the effect that when the motor 32 works normally, the motor 32 drives the driving wheel 31 to rotate through the unidirectional transmission mechanism, and then drives the conveyor belt 2 to move; when 1 motor fails and does not work, the driving wheel 31 is separated from the motor 32 through the unidirectional transmission mechanism, namely, the driving wheel 31 can normally rotate under the transmission of the conveyor belt 2. In this way, when any motor 32 in the driving wheel 31 fails and does not work, only one motor 32 works normally to drive the whole conveyor belt 2 to move, the whole conveyor is not stopped, and the continuity and reliability of the work of the device are ensured.
In a specific embodiment, since the motor 32 and the driving wheel 31 are in a transmission relation, the motor 32 can be arranged in a quick-change structure, for example, the motor 32 and the connecting piece 5 are arranged in a direct detachable plug-in type, a boss on an output shaft of the motor, and a groove matched with the boss and arranged in the unidirectional driving mechanism are arranged, and if a ratchet mechanism is adopted, the groove is arranged in a shaft hole in the pawl assembly; if a one-way clutch mechanism is adopted, a groove is arranged in a shaft hole in the motor connecting section; if a one-way bearing mechanism is used, a groove is arranged in the shaft hole of the inner ring. By this arrangement, when replacement is necessary, the faulty motor is pulled out and a new motor 32 is inserted.
The unidirectional transmission mechanism can be a ratchet mechanism, and the ratchet mechanism is an existing transmission mechanism and comprises a ratchet assembly 41 and a pawl assembly 42 as shown in fig. 3 to 5, wherein the ratchet assembly 41 is in transmission connection with the driving wheel 31, and the pawl assembly 42 is in transmission connection with an output shaft of a motor. As shown in fig. 4, the pawls of the pawl assembly 42 are connected by an elastic member such as a spring to be in an extended state, and when the motor is operating normally, the pawl assembly 42 is driven to rotate in the arrow direction, the pawls of the pawl assembly 42 abut against the grooves of the ratchet assembly 41, and the ratchet assembly 41 is driven to rotate in the arrow direction. As shown in fig. 5, when the motor fails and cannot rotate, the ratchet assembly 41 and the pawl assembly 42 are separated from the unidirectional driving relationship, that is, the motor connecting the driving wheel 31 connected with the ratchet assembly 41 and the pawl assembly 42 is separated from the unidirectional driving transmission relationship, the pawl assembly 42 does not rotate, and the pawl of the pawl assembly 42 is pressed back into the groove of the pawl assembly 42 when the ratchet assembly 41 rotates, so that the ratchet assembly 41 can rotate freely along the arrow direction, thereby ensuring the normal movement of the conveyor belt 2.
The one-way transmission mechanism may be a one-way clutch mechanism, as shown in fig. 6 to 7, which includes a wheel connection section 51 and a motor connection section 52, wherein the wheel connection section 51 is in transmission connection with the driving wheel 31, and the motor connection section 52 is in transmission connection with an output shaft of the motor. One end of the wheel connecting section 51 is provided with a one-way groove structure, and one end of the motor connecting section 52 is provided with a one-way groove structure matched with the one-way groove structure, as shown in fig. 6, when the motor connecting section 52 rotates in the direction of the arrow shown in the figure, the wheel connecting section 51 also rotates in the direction of the arrow shown in the figure due to the mutual limiting effect of the two one-way grooves. As shown in fig. 7, when the motor fails and cannot rotate, the wheel link section 51 and the motor link section 52 are disengaged from the one-way driving relationship, that is, the motor connecting the driving wheel 31 connected to the wheel link section 51 and the motor link section 52 is disengaged from the one-way driving relationship, the motor link section 52 does not rotate, and the one-way grooves of the wheel link section 51 and the one-way grooves of the motor link section 52 are separated from each other, so that the wheel link section 51 can freely rotate in the arrow direction, thereby ensuring the normal movement of the conveyor belt 2. Specifically, the motor connecting sections 52 may be configured to be elastically connected (such as a spring), and the motor connecting sections 52 may slide on the output shaft of the motor 32; when the motor 32 works normally, the elastic piece applies elastic force to the motor connecting section 52, so that the motor connecting section 52 is abutted with the wheel connecting section 51, and normal transmission connection is kept; when the driving motor is not rotated in the abnormal state, the motor connecting section 52 is not rotated, and the wheel connecting section 51 pushes the motor connecting section 52 in the axial direction due to the elasticity of the spring 53 to move to the right in the drawing, so that the unidirectional groove of the wheel connecting section 51 and the unidirectional groove of the motor connecting section 52 are separated from each other, and the transmission connection is released.
The unidirectional transmission mechanism may be a unidirectional bearing, and the unidirectional bearing includes an outer ring and an inner ring, where the outer ring is in transmission connection with the driving wheel 31, and the inner ring is in transmission connection with an output shaft of the motor. When the motor drives the inner ring to rotate along the transmission direction of the unidirectional drive, the inner ring drives the outer ring to rotate together and drive the driving wheel to rotate together. When the motor fails and cannot rotate, the inner ring and the outer ring are separated from the unidirectional driving relationship, namely, the motor which is connected with the driving wheel 31 connected with the outer ring and the inner ring is separated from the unidirectional driving transmission relationship, the inner ring does not rotate, and the outer ring can freely rotate along the moving direction of the conveyor belt.
The utility model also provides an embodiment of a conveyor system comprising a conveyor device as described above. The conveyer belt device is arranged in the conveyer belt device, when one of two motors in the conveyer belt device fails, the failed motor stops running, and because the motor is in transmission connection with the driving wheel through the unidirectional driving mechanism, the motor is in transmission connection with the driving wheel, the driving wheel can rotate along the driving direction through the driving of the conveyer belt, and the driven wheel can be used, meanwhile, because the other motors work normally, the whole conveyer belt can work normally under the driving of the other motors, and the reliability of the conveyer belt system is ensured.
The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
