Description

Driving device of belt conveying trolley

Technical Field

The utility model relates to a drive technical field specifically is a belt conveyor trolley's drive arrangement.

Background

In the production process of the crushing system, the task of conveying ores into each ore storage bin is completed by a trolley on a belt conveyor; the key to the normal operation of the trolley is the driving device.

Whether the operation of dolly is normal lies in drive arrangement crucial, and the installation form is as follows:

firstly, a main belt conveyor is arranged on an ore storage bin, and a middle-sized manganese steel track with the weight of 25 kilograms or more is arranged on a belt frame (different from a common belt frame, specially designed and parallel to the plane of the ore storage bin and capable of supporting the weight of a trolley) of the main belt conveyor;

secondly, designing a set of triangular trolley, mounting two sets of (front and back) rail wheels at the bottom of the trolley, and placing the trolley on a rail of the belt conveyor; the front is high and the rear is low, the angle (slope) is generally not more than 30 degrees, as seen in the direction of belt travel; the head wheel, the steering wheel, the upper layer roller frame, the carrier roller, the discharging hopper, the driving device and the like are arranged on the trolley;

thirdly, a small car head wheel, a steering wheel, a head wheel, a tail wheel, a waist wheel and the like of the main belt conveyor are wound together, and the small car and the main belt conveyor share a belt and a blanking funnel;

fourthly, a set of driving device is arranged on the trolley frame, the trolley can be driven to walk back and forth on the track of the main belt conveyor, the main belt conveyor is fixed, and the running direction of the belt is not changed

The trolley is made of steel, and the weight of the trolley is about 30 tons; during the production process, about 10 tons of ore are arranged on the belt.

The driving principle of the trolley is as follows: a set of chain gears is arranged on one side of a front end wheel shaft of the trolley; a set of speed reducer is arranged on the trolley frame, the input side of the speed reducer is driven by a three-phase asynchronous motor, and the output side of the speed reducer is also provided with a set of chain gear; connecting the two gears together by a chain; the motor drives the speed reducer and the chain to complete the front and back walking of the trolley; the stopping of the trolley is completed by a brake device at the tail part of the motor.

So there are the following disadvantages:

the disadvantages of braking are as follows: the brake device is arranged in a fan cover at the tail part of the motor, cannot be seen in the operation process and cannot be used for routing inspection and checking; the brake is difficult to adjust and replace; the trolley bears great force of belt running in the running process, when the brake is tightened, the brake pad can not be completely opened when the trolley walks, the abrasion is serious, and the trolley is often damaged; the friction between the brake block and the tail part of the motor is serious, so that the temperature of the motor is overhigh, and the phenomena of smoking of the brake block, burning of a motor coil and burning of a fan are caused; when the brake is loosened, the trolley can slowly walk towards the running direction of the belt under the driving of the main conveying belt when being stopped, and the trolley cannot be braked, so that the trolley is dangerous.

The disadvantages of the chain are: at the moment when the trolley starts to walk and stops, due to the running of the belt, the trolley is subjected to large force and large inertia, the chain and the speed reducer are also subjected to large impact force, the chain is frequently disconnected, and the chain is disconnected several times a day in serious cases, so that the maintenance amount is large, the cost is high, and the production is influenced; after the chain is disconnected, a brake device is not arranged on a wheel shaft of the trolley, and the trolley is driven by the belt to continue to move in the belt running direction; the trolley travels faster and faster due to a certain distance of the track, and is stopped until the trolley collides with a blocking device (preventing the trolley from falling off the belt frame); due to the inertia of the trolley, the collision force is very large, the destructive power is very strong, even the blocking device is damaged by collision, the emergency is called a sports car, and several serious personal safety accidents and equipment accidents occur in the running process; the production is seriously influenced, and the production capacity of the crushing system cannot be achieved.

Therefore, the driving device of the belt conveying trolley is improved.
