For achieving the above object, multi-point throttling belt hypervelocity checking brake of the present utility model, comprise speed detector, electrical control gear, hydraulic power unit, speed increasing mechanism, oil pump, also comprise symmetry and be located at the support that belt conveyer both sides are connected as a single entity by angle steel, the bilateral symmetry of support is provided with the oil cylinder be connected with hydraulic power unit, fixing hydraulic booster axle is on the piston rod provided with between two oil cylinders, hydraulic booster axle two ends are respectively equipped with chevron pointing link span, two pressure rolls contacted with lower floor adhesive tape are arranged with between two chevron pointing link spans, lower floor's adhesive tape bottom between two pressure rolls is provided with friction drag roller, friction drag roller one end is connected with speed increasing mechanism through coupler, speed increasing mechanism is connected with oil pump, described speed detector is located at above lower floor's adhesive tape, through sensor, information is passed to electrical control gear.
Beneficial effect: the utility model multi-point throttling belt hypervelocity checking brake, produce the unsafe problems of hypervelocity for lower fortune belt, the problem such as heating that disc type brake produces adopts multiple spot to arrange, stressed excessive defect is produced in same cross section when can overcome braking, the power of solving focuses mostly on and results from drive wheel circumferences, adhesive tape load on same section is excessive, the problem that the damage of load-transfer device makes the life-span of load-transfer device decline, compared with prior art tool has the following advantages:
1. solve the heating problem that disc type brake produces.In load-transfer device stop mechanism, conventional machinery brake wheel (block, dish) carries out dry friction braking; Can produce spark due to it and burn phenomenon, safely harm is produced to shaft production, and in belt conveyer braking procedure, brake equipment not only wants the effect that can overcome load moment, constantly will absorb the heat that braking procedure produces simultaneously.Therefore, national regulations, band-type brake heating temp must not more than 150 degree, mechanical brake wheel apparatus conventional at present generally can not reach this regulation, this device is without the need to mechanical brake wheel (block, dish) device, solve brake wheel heating, produce the problems such as spark, improve the coefficient of safety in production, improve the life-span that makes of equipment;
2. can lay electric-controlled hydraulic control by multiple spot, each engine installation becomes an independent brake unit, can solve B.P. balance and brake delay issue preferably;
3. directly control brake equipment owing to have employed load-transfer device speed signal, on-line monitoring and monitoring in real time can be implemented easily, the stability that the equipment that improves runs and reliability.

Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Fig. 1 Fig. 2, multi-point throttling belt hypervelocity checking brake of the present utility model, is formed primarily of support 1, speed detector 2, hydraulic booster axle 3, hydraulic power unit 4, oil cylinder 5, pressure roll 6, friction drag roller 7, speed increasing mechanism 8, oil pump 9 and electrical control gear 12.The both sides of belt conveyer upper strata adhesive tape 10 and lower floor's adhesive tape 11 are located at by the angle steel symmetry that is connected as a single entity in the middle part of support 1, the bilateral symmetry of support 1 is provided with the oil cylinder 5 be connected with hydraulic power unit 4, fixing hydraulic booster axle 3 is on the piston rod provided with between two oil cylinders 5, hydraulic booster axle 3 two ends are respectively equipped with chevron pointing link span, two pressure rolls 6 contacted with lower floor adhesive tape 11 are arranged with between two chevron pointing link spans, lower floor's adhesive tape 11 bottom between two pressure rolls 6 is provided with friction drag roller 7, friction drag roller 7 one end is connected with speed increasing mechanism 8 through coupler, speed increasing mechanism 8 is connected with oil pump 9, described speed detector 2 is located at above lower floor's adhesive tape 11, through sensor, information is passed to electrical control gear 12.
Principle of work and working process: in normal operation, pressure roll 6 does not contact with lower floor adhesive tape 11, only when needs slow down or brake, the signal that Negotiation speed detecting device 2 provides makes oil cylinder move down, allow lower floor's adhesive tape 11 and pressure roll 6, friction drag roller 7 close contact, the friction drag roller 7 producing power drives oil pump 9 to work by speed increasing mechanism 8, and flow regulating valve makes system loads with throttling loading regime, thus makes load-transfer device obtain lock torque.When load-transfer device exceeds the speed limit, speed detector 2 provides overspeed signal to electrical control gear 12, electrical control gear 12 sends electric signal to hydraulic power unit electromagnetic valve, control two oil cylinders 5 and drive that hydraulic booster axle 3 is parallel to be moved down simultaneously, two pressure rolls 6 on chevron pointing frame move down thereupon and act on lower floor's adhesive tape 11, by lower floor's adhesive tape 11 to pressing down, under the effect of lower floor's adhesive tape 11 bottom friction drag roller 7, make load-transfer device produce friction drag, force load-transfer device to slow down.Two pressure rolls 6 form Samsung structure with friction drag roller 7, by pressing down of pressure roll 6, cornerite between load-transfer device and friction drag roller 7 is increased, thus the friction force between the multiplying wheel of load-transfer device and speed increasing mechanism 8 is increased, multiplying wheel obtains larger torque.Speed increasing mechanism 8 is arranged on underframe by bearing seat, and the input shaft of speed increasing mechanism 8 is connected with the output shaft of friction drag roller 7, realizes mechanism's slow speed of revolution to high-revolving transformation, and speed increasing mechanism 8 output wheel is connected with oil pump 9.Make Hydraulic Pump obtain high pressure oil by speed increasing mechanism 8, under the effect of flow regulating valve, make system reach deceleration object.By hydraulic power unit 4, friction drag roller 7 is made to obtain larger rotary resistance, by reaching with the contact of load-transfer device the object reducing load-transfer device speed.According to the needs of conveyer belt length, multiple spot can be carried out in load-transfer device both sides and lay hypervelocity checking brake, to obtain the brake snub of multiple spot.
