Description
Technical Field
The utility model relates to a belt conveyor, in particular to a multi-power machine head driving device of a mining belt conveyor; belonging to mining machinery.
Background
The currently widely used belt conveyors for mines generally use a single-power drive, i.e. constituted by a motor driving a reducer, a driving roller connected to the reducer by means of a coupling (CN 202924270U). The single-power handpiece driving device is simple, but when the conveying distance is relatively long and the load is relatively large, the conveying belt is easy to loosen. In order to increase friction between the belt and the drum, measures such as increasing the diameter of the driving drum, increasing the wrap angle of the belt and the drum by increasing the tension roller, increasing the power of the motor and the like have to be taken. However, because the coal mine tunnel is narrow, the diameter of the driving roller is increased, the number of the tensioning rollers is increased, and the like, so that more mine space is occupied, and the coal mining operation is influenced.
To overcome the above-described drawbacks, the utility model patents entitled "a double drive belt conveyor (CN 204713957U)", "a double drive apparatus for a belt conveyor (CN 208345124U)", respectively, disclose a belt conveyor head drive apparatus having double power. The technical proposal of the two patents is that a motor is used for driving a speed reducer, and the speed reducer drives two rollers to rotate simultaneously through two sets of chain transmission devices respectively. The dual-power belt conveyor head driving device can overcome the defects that a conveying belt is easy to loosen, the diameter of a driving roller needs to be increased and the like to a certain extent, but can bring the following defects:
1) The chain transmission device has a loose structure and large installation space, and occupies a larger coal mining space;
2) The chain transmission device and the speed reducer have low independent transmission efficiency, high power loss and large vibration and noise;
3) Because the motor needs larger starting torque when starting, and the torque needed in normal operation is smaller; in order to ensure that the belt conveyor can normally operate, a high-power motor is matched according to the high torque required by starting, so that the motor has high energy consumption and high operation cost;
4) As only one motor is used for driving, and the two driving rollers are connected through the chain transmission device, once the motor fails, the whole conveyer belt breaks down to stop running, and the reliability is poor.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the multi-power machine head driving device of the mining belt conveyor, which has the advantages of compact structure, low power consumption, stable and safe operation and can be used in a narrow inclined roadway.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the device comprises a power head for driving the conveying belt to move; the power head consists of a first permanent magnet synchronous electric roller, a second permanent magnet synchronous electric roller and a third permanent magnet synchronous electric roller, wherein the first permanent magnet synchronous electric roller and the second permanent magnet synchronous electric roller are fixed on the frame, the third permanent magnet synchronous electric roller is fixed on the unloading frame, a brake disc is fixed on the end face of the second permanent magnet synchronous electric roller, and a disc type hydraulic brake fixed on the frame is matched with the brake disc.
Two end surfaces of the second permanent magnet synchronous electric roller are respectively fixed with a brake disc, two sets of disc-type hydraulic brakes are fixed on the frame, and each disc-type hydraulic brake is matched with the corresponding brake disc.
And a backstop is arranged on the first permanent magnet synchronous motorized pulley or the third permanent magnet synchronous motorized pulley.
A tensioning roller fixed on the unloading frame is arranged between the second permanent magnet synchronous motorized pulley and the third permanent magnet synchronous motorized pulley.
Compared with the prior art, the utility model has the following advantages due to the adoption of the technical scheme:
1) The novel driving device formed by three permanent magnet synchronous electric rollers is adopted to replace the traditional driving device formed by one motor, one speed reducer, two chain transmission mechanisms and two rollers, so that the structure can be greatly simplified, the system volume can be reduced, the installation requirement of equipment in a narrow space of a coal mine can be met, and the vibration and noise caused by multi-ring transmission can be reduced;
2) Because parts with low transmission efficiency such as a speed reducer, a chain transmission mechanism, a coupler and the like are omitted, the power loss can be reduced, and the energy can be saved;
3) The driving device is formed by driving three permanent magnet synchronous electric rollers, so that the load change can be adapted by adjusting the working conditions of the three permanent magnet synchronous electric rollers, and the operation efficiency and the electric energy consumption are simultaneously considered;
4) The brake device consisting of the brake disc and the disc type hydraulic brake is added, emergency braking operation is carried out on the whole conveying line according to the requirement, and the safety is high;
5) The backstop is added, so that accidents such as reverse sliding and the like caused by faults such as power failure and the like when the conveying belt passes through an inclined roadway can be effectively avoided, and the operation safety and reliability are further improved.
