Description

Technical Field

[0001] The utility model relates to the technical field of tubular belt conveyors, in particular to a novel deflection correction device for tubular belt conveyors. Background Art

[0002] During the upstream and downstream transportation of tubular belt conveyors, uneven material weight often creates uneven pressure on the conveyor, causing the tubular belt to deviate from the conveyor centerline. This not only reduces transportation efficiency but can also cause material spillage along the conveyor line, while also damaging the tubular belt and shortening its service life.

[0003] According to the publication number: CN107720099B, a circular tube belt conveyor belt deviation correction device and correction method are disclosed. This technology discloses "a circular tube belt conveyor belt deviation correction device, including a frame, a deviation correction sensor, an electrical control system and a deviation correction actuator, characterized in that the deviation correction sensor and the deviation correction actuator are both fixed to the frame, and the deviation correction sensor includes a sensor turntable surrounding the outer side of the circular tube belt conveyor belt, and the sensor turntable is provided with a plurality of displacement sensors, a sensor swing arm, and a turntable counterweight plate." The device has the following technical effects: "the roller deflects on the eccentric fulcrum of the deflection, thereby increasing the correction component. The roller can generate displacement or deflection synchronously in the three directions of the X-axis, Y-axis and Z-axis. Compared with the displacement of the traditional plane angle, the correction component force is greatly increased by the sum of the applied forces in the three directions, thereby improving the correction efficiency."

[0004] The above solution includes six rollers and a lengthy and complex hexagonal chain drive system. This design not only requires high installation precision but also presents a series of disadvantages in terms of subsequent maintenance and repair. The inherent drawbacks of the chain drive system, such as wear, noise, and the need for regular lubrication, increase the difficulty and cost of maintenance and potentially impact the long-term stable operation of the equipment. Therefore, this solution may face many inconveniences and limitations in actual application. Utility Model Content

[0016] Beneficial effects

[0017] The utility model provides a new tubular belt conveyor deflection correction device. Compared with the existing technology, it has the following advantages:

[0018] (1) When installing the actuator, the two ends of the shaft core are respectively embedded in the shaft seats on both sides, and then the shaft is rotated to drive the gear, and the gear drives the pin to retract inward through the rack, and then the mounting head on the shaft cover is inserted into the mounting hole on the shaft seat, and then the rotating shaft is released and the rack is pushed by the spring rebound pressure to drive the pin to extend outward and insert it into the interior of the mounting head, thereby fixing the auxiliary component to the mounting component, and fixing the actuator to the mounting component through the auxiliary component; so that the actuator can be replaced quickly and conveniently when it is worn.

[0019] (2) The worm is driven by the output end of the motor to drive the worm wheel to rotate, and the worm wheel drives the base to rotate through the shaft column. The base drives the actuator to rotate through the installation component and the auxiliary component, so that the rotation direction of the first roller is opposite to the deflection direction of the tubular conveyor belt, thereby realizing the correction of the tubular conveyor belt; at the same time, the tubular conveyor belt is limited by the second rollers on both sides, and the positions of the limiting mechanisms on both sides are fixed, which can prevent the correction mechanism from deflecting the tubular conveyor belt at an excessively large angle when correcting the tubular conveyor belt.

[0027] The adjustment assembly 21 includes a base 211 to which the top of the main frame 1 and the bottom of the upper end of the frame 5 are fixed;

[0028] The mounting assembly 22 includes a mounting bracket 221 provided on the adjustment assembly 21, a shaft seat 222 fixed on both sides of the top of the mounting bracket 221, mounting holes 223 provided on both sides of the top of the shaft seat 222, a shaft rod 224 rotatably mounted in the middle of the shaft seat 222, a gear 225 fixed to the outer wall of the shaft rod 224, guide rods 226 fixed on the upper and lower sides of the shaft seat 222, a rack 227 slidably mounted on the mounting hole 223, and a latch 228 fixed to the outer end of the rack 227;

[0029] The actuator assembly 23 includes a shaft core 231 mounted on the mounting assembly 22 and a first roller 232 rotatably mounted on the outer wall of the shaft core 231;

[0030] The auxiliary component 24 includes a shaft cover 241 mounted on the upper end of the mounting frame 221 and mounting heads 242 fixed on both sides of the bottom of the shaft cover 241 .

[0031] In this embodiment, when the actuator 23 is installed, the two ends of the shaft core 231 are respectively embedded in the shaft seats 222 on both sides, and then the shaft 224 is rotated to drive the gear 225, and the gear 225 drives the pin 228 to retract inward through the rack 227, and then the mounting head 242 on the shaft cover 241 is inserted into the mounting hole 223 on the shaft seat 222, and then the rotating shaft 224 is released and the pressure of the spring 229 rebounds to push the rack 227 to drive the pin 228 to extend outward and insert it into the interior of the mounting head 242, thereby fixing the auxiliary component 24 on the mounting component 22, and fixing the actuator 23 on the mounting component 22 through the auxiliary component 24; making it convenient and quick to replace the actuator 23 when it is worn.

[0032] Specifically, the adjustment component 21 also includes a shaft column 212 rotatably mounted on the upper end of the base 211, a base 213 fixed on the upper end of the shaft column 212, and a mounting frame 221 fixed on the top of the base 213, a worm gear 214 fixed on the outer wall of the shaft column 212, a worm 215 rotatably mounted on the upper end of the base 211, and the worm 215 is engaged with the worm gear 214 for transmission, and a motor 216 mounted on the upper end of the base 211 is used to drive the worm 215 to rotate.
