Abstract
The utility model relates to a brake device for a belt conveyor, which comprises a brake disc and an electro-hydraulic arm disc brake matched with the brake disc, wherein the brake disc is connected with a rotating shaft which is connected with a drum shaft of the belt conveyor or a low speed shaft of a reducer by a coupling. The brake device has the benefits that 1, the braking torque is large; 2, the electro-hydraulic arm disc brake is driven by an electro-hydraulic impeller, a special hydraulic station is not required, the system is simple, and the manufacturing cost is low; and 3, the brake device is simple in structure, convenient to install and maintain, and applicable to severe environments.
Description
Technical field
The utility model relates to a kind of brake equipment of belt conveyer, is used for the braking of the middle-size and small-size belt conveyer of upper fortune and lower fortune.
Background technology
Belt conveyer is the widely used transportation devices of department such as coal, mine, chemical industry, metallurgy, building materials, electric power, light industry and communications and transportation.The indispensable transportation device especially in the colliery, " safety regulations in coal mine " the 373 regulation, the belt conveyer that uses in the gradient tunnel during upper fortune, must be installed anti-kickback device and brake equipment simultaneously; During lower fortune, must the installing brake equipment.
Small-sized or universal upper conveying belt type conveyer adopts the power hydraulic pressure block brake usually, and this mode is arranged in drg on the high speed shaft of retarder, and advantage is that simple in structure, required lock torque is little, the saving space.But install owing to make, brake wheel is difficult to accomplish the quality complete equilibrium.As everyone knows, to turning unit, maskant unbalance just will produce centnifugal force, according to Newton's law, centnifugal force F=m ω 2r, its size square is directly proportional with rotative speed, the high-speed shaft of speed reducer rotating speed is high, even unbalanced quality is little, also can produce very large centnifugal force.Because the existence of centnifugal force, reducer input shaft and motor reel will produce additional bending moment, their strained condition is become and is born simultaneously moment of flexure and moment of torsion by the pure torsion that only bears of design, its consequence, gently then produce vibrations, retarder because of the ring wear leakage of oil, can cause the fracture of high-speed shaft of speed reducer and motor reel when serious.Long distance, high spud angle, high-performance belt conveyer often adopt more failure-free disc brake apparatus of performance, be installed on drum shaft or the reductor slow-speed shaft, damper brake is fluid control, need to be equipped with Hydraulic Station, system complex, price is the decades of times of power hydraulic pressure block brake, and it is improper to be used on the middle-size and small-size belt cost performance.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of brake equipment of belt conveyer,
Simple in structure, easy to operate, cost is low, is particularly useful for middle-size and small-size belt conveyer.
The utility model is realized by following measures:
The brake equipment of a kind of belt conveyer of the present utility model, the power hydraulic pressure arm plate disc brake that comprises brake disc and match with brake disc, described brake disc is connected in the rotating shaft, and described rotating shaft connects drum shaft or the reductor slow-speed shaft of this belt conveyer by coupler.
Above-mentioned brake disc both sides are provided with the bearing seat parallel with brake disc, and described rotating shaft is arranged between the bearing seat.
The beneficial effects of the utility model are:
1, lock torque is large; 2, power hydraulic pressure arm plate disc brake drives as electric liquid pusher, need not special Hydraulic Station, and system is simple, low cost; 3, simple in structure, convenient for installation and maintenance, be applicable in the abominable situation of environment.
Description of drawings
Fig. 1 is the structural representation of a kind of coupled condition of the present utility model.
Fig. 2 is the structural representation of another kind of coupled condition of the present utility model.
Fig. 3 is structural representation of the present utility model.
Fig. 4 be among Fig. 3 A to structural representation.
Among the figure: 1. motor, 2. high speed shaft coupler, 3. reductor, 4. slow-speed shaft coupler, 5. cylinder, 6. coupler, 7. power hydraulic pressure arm plate disc brake, 8. brake disc, 9. base, 10. bearing seat, 11. rotating shafts.
The specific embodiment
Such as Fig. 1,2,3, shown in 4, the brake equipment of a kind of belt conveyer of the present utility model, the power hydraulic pressure arm plate disc brake 7 that comprises brake disc 8 and match with brake disc 8, brake disc 8 is connected in the rotating shaft 11, brake disc 8 is connected with the rotating shaft flat key, brake disc 8 both sides are provided with the bearing seat 10 parallel with brake disc 8, rotating shaft 11 is arranged between the bearing seat 10, diaxon bearing 10 is fixed on the base 9 that is independent of the belt conveying machine equipment, rotating shaft is connected with drum shaft or retarder slow-speed shaft by coupler 6, and power hydraulic pressure arm plate disc brake 7 is installed on the base 9.The motor 1 of this belt conveyer connects the reductor high speed shaft by the high speed shaft coupler, and the reductor slow-speed shaft connects drum shaft by the slow-speed shaft coupler.
During normal operation, motor 1 drives the reductor high speed shaft and rotates, and the reductor slow-speed shaft drives drum shaft and rotates, and also drives brake disc 8 and rotates.In the time will braking, start power hydraulic pressure arm plate disc brake 7,7 pairs of brake discs of power hydraulic pressure arm plate disc brake apply lock torque, realize braking function.Because brake disc 8 is connected to the slow drum shaft of rotating speed or retarder slow-speed shaft, so the rotating speed of brake disc 8 itself is just slow, thereby when braking, produce larger moment, shake little, good braking effect.
Above-described embodiment is described to be to specify this patent; though describe by specific term in the literary composition; but can not limit with this protection domain of this patent; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
Claims (2)
1. the brake equipment of a belt conveyer, it is characterized in that: the power hydraulic pressure arm plate disc brake that comprises brake disc and match with brake disc, described brake disc is connected in the rotating shaft, and described rotating shaft connects drum shaft or the reductor slow-speed shaft of this belt conveyer by coupler.
2. the brake equipment of described belt conveyer according to claim 1, it is characterized in that: described brake disc both sides are provided with the bearing seat parallel with brake disc, and described rotating shaft is arranged between the bearing seat, and described bearing seat is fixed on independently on the base.
