Description
Technical field
The utility model relates to a kind of arresting agency, especially relates to a kind of broken-belt catching mechanism of coal conveyor belt.
Background technology
At present, in the coal production process, used a large amount of belt transporters, belt transporter generally has certain setting angle, from several years to twenties degree, does not wait, in the top rade travelling belt, there will be belt broken belt accident, after belt fracture, the coal of belt and upper transportation thereof meeting slippage, to the bottom of belt feeder, causes serious accident.So the safety regulations in coal mine regulation, upper fortune belt transporter need to be installed broken-belt catching mechanism, in order to avoid after the belt broken belt, cause great serious accident.Existing coal conveyor belt broken-belt catching mechanism, a part is mechanical, although structure simply can't realize the test maintenance, is not easy to daily attention, easily causes failure in a long time; Part broken-belt catching mechanism is fluid pressure type, and complex structure, equipment be huge, involve great expense; Part broken-belt catching mechanism is the spring electromagnetic type, and equipment is little but can not carry out daily artificial test service work, can not guarantee that equipment is in normal condition.
Summary of the invention
For the deficiency of the broken-belt catching mechanism that solves existing belt transporter, the utility model provides a kind of broken-belt catching mechanism of coal conveyor belt, and it is simple in structure, can realize testing at ordinary times service work, and cheap.
The technical scheme that its technical matters that solves the utility model adopts is: the arresting agency bilateral symmetry is arranged, each side is comprised of pressing plate, cam, pneumatic actuator, pneumatic actuator inside is comprised of cylinder A, cylinder piston rod A, gear, tooth bar A, axle drive shaft, cylinder piston rod A is connected with tooth bar A, tooth bar A and gear engagement, cylinder piston rod A moves forward and backward band carry-over bar A and moves, the rotation of tooth bar A moving belt moving gear, and gear is fixed on the axle drive shaft of pneumatic actuator; The belt of belt transporter is placed between pressing plate and cam, the axle drive shaft of pneumatic actuator is connected with camshaft, the axle drive shaft rotation of pneumatic actuator can be with the moving cam rotation, and the cam rotation can change the distance between cam and pressing plate, with realization, the extruding of belt is arrested and is discharged; Arresting agency also is equipped with cam rotation home sensor and rotation final position sensor.
When having the broken belt accident to occur, the cylinder piston rod A of the cylinder A of arresting agency stretches out, tooth bar A is mobile and driven gear rotation and then, the axle drive shaft rotation of gear driven pneumatic actuator, cam is rotation and then, distance between cam and pressing plate diminishes, and belt can be squeezed between cam and pressing plate, realizes arresting the purpose of belt.
During the day-to-day test maintenance, arresting agency stretches out, retracts by cylinder piston rod A, with flexible, the rotation of gear of carry-over bar A, the rotation of cam, and rotate by cam the run location that home sensor and rotation final position sensor are pointed out cam, realize checking whether the work of cylinder A, cylinder piston rod A and tooth bar A, gear, cam is in normal condition.
In pneumatic actuator, also be furnished with cylinder B, cylinder piston rod B, tooth bar B, cylinder B and cylinder A reversed arrangement, cylinder piston rod B is connected with tooth bar B, and tooth bar B also meshes with gear.Cylinder piston rod B and cylinder piston rod A synchronously stretch out, retract, to realize that gear is better rotated to control.
The beneficial effects of the utility model are, have solved the unreasonable problem of coal conveyor belt broken-belt catching mechanism, and are simple in structure, and the test maintenance is convenient, and equipment manufacturing cost is cheap.
