A whole machine frame is formed by connecting a side frame and an upper cross beam, a lower cross beam, an upper longitudinal beam and a lower longitudinal beam. An upper pressing rotation beam connected with an upper rotation shaft is arranged above an upper rubber belt, and a supporting rotation beam connected with a lower rotation shaft is arranged below the upper rubber belt. A detection mechanism is arranged above a lower rubber belt, and a lower capturing support capturing an upper pressing shaft is connected below the lower rubber belt. A linkage mechanism is connected with the lower rotation shaft with a balancing weight. A locking mechanism is connected with the lower longitudinal beam, and an unlocking mechanism is connected with the detection mechanism. The upper longitudinal beam and the lower longitudinal beam are provided with bearing seats. The passive full-section belt breakage protection device is simple in structure and fast in braking speed, the passive power mode is adopted, the shortcomings of hydraulic pressure leakage and electric appliance interference are avoided, and the rubber belts can be prevented or stopped from sliding down fast and effectively.
Description
Technical field
The utility model relates to a kind of belt break protection device for belt conveyor, especially a kind of passive full-section belt fender guard.
Background technology
Extensive utilization along with conveyer under coal mine, the phenomenon that the broken belt accident occurs is also constantly increasing, high spud angle particularly, long distance, the travelling apron that transportation volume is large, starting, the unstable stage of braking, tractive force and force of inertia that actuating device is applied on load-transfer device will be propagated with certain velocity of wave in band, stack, reflection, add the impact of other factors, in the conveyer band, cause changeable STRESS VARIATION, if its instantaneous peak value stress surpasses permissible value, will damage travelling apron and make it disrumpent feelings, cause long stopping production and heavy economic losses, personal casualty even.Now widely used conveyer broken-belt protecting device, its complex structure, retro-speed is slow, and power consumption is large, and hydraulic pressure is revealed, and easily current collector disturbs, and can not fast and effeciently brake and stop adhesive tape to glide.
Summary of the invention
The purpose of this utility model is to provide a kind of passive full-section belt fender guard for delivery of machine; this apparatus structure is simple, retro-speed is fast; adopt passive power mode, avoid the drawback that hydraulic pressure is revealed, electrical equipment disturbs, can fast and effeciently brake and stop adhesive tape to glide.
The purpose of this utility model is achieved in that bogie side frame is by the integral-rack that is connected to form with entablatrance, cross sill, upper longeron and lower longeron, there is the upper pressure rotating beam be connected with upper S. A. the top of adhesive tape, there is the support rotating beam be connected with Shaft below, there is testing agency the top of lower adhesive tape, the below have under connection arrest upper pressure axial under arrest support, the Shaft of link gear connecting band clump weight, catch gear are connected on lower longeron, and release mechanism connects testing agency.
On upper longeron and lower longeron, bearing seat is arranged.
The beneficial effects of the utility model are: simple in structure, retro-speed is fast, adopts passive power mode, avoid the drawback that hydraulic pressure is revealed, electrical equipment disturbs, and can fast and effeciently brake and stop adhesive tape to glide.
The accompanying drawing explanation

Fig. 2 is the right TV structure figure of Fig. 1.
1 integral-rack in figure, 2 entablatrances, 3 support on rotating beams, 4 bogie side frames, 5 and press rotating beam, 6 cross sills, 7 adhesive tapes, 8 times adhesive tapes, 9 bearing seats, 10 to carry frame, 11 link gears, 12 diagonal ligaments, 13 release mechanisms, 14 catch gears, arrest support, 16 diagonal ligament seats for 15 times, arrest upper pressure axial for 17 times, S. A. on longeron, 23 on 18 times longerons, 19 clump weights, 20 testing agencies, 21 Shafts, 22.
The specific embodiment
Embodiment: bogie side frame 4 by with entablatrance 6, cross sill 2, upper longeron 22 and lower longeron 18 be connected to form integral-rack 10, there is the upper pressure rotating beam 5 be connected with upper S. A. 23 top that is connected to the adhesive tape 7 on bogie side frame 4, there is the support rotating beam 3 be connected with Shaft 21 below, there is testing agency 20 top that is connected to the lower adhesive tape 8 on conveyer frame 1, below have under connection arrest upper pressure axial 17 under arrest and support 16, the Shaft 21 of link gear 11 connecting band clump weights 19, catch gear 14 is connected on lower longeron 18, release mechanism 13 connects testing agency 20, on upper longeron 22 and lower longeron 18, bearing seat 9 is arranged.
This device comprises across the integral-rack 10 that is arranged on conveyer frame 1 both sides and being fixedly connected with ground by anchor pole; Integral-rack 10 mainly contains bogie side frame 4 and is formed by connecting by the bolt group with entablatrance 6, cross sill 2, upper longeron 22 and lower longeron 18.On integral-rack 10, bogie side frame 4 is provided with diagonal ligament 12 and connects by diagonal ligament seat 16, adhesive tape 7 tops be provided with S. A. 23, upper pressure rotating beam 5, adhesive tape 7 belows be provided with support rotating beam 3, Shaft 21, under arrest lower last item 15, testing agency 20, link gear 11, catch gear 14, release mechanism 13 and clump weight 19; Lower adhesive tape 8 belows are provided with down to arrest supports 15; Supporting rotating beam 3 is that a cuboid mechanism and Shaft 21 are welded, bearing seat 9 is bolted on lower longeron 18, supporting rotating beam 3 upper surfaces is provided with skid resistant course, increases friction coefficient and avoid injuring adhesive tape, upper pressure rotating beam 5 is that a cuboid mechanism and upper S. A. 23 are welded, bearing seat 9 is bolted on upper longeron 22, supports rotating beam 3 upper surfaces and is provided with skid resistant course, increases friction coefficient and avoid injuring adhesive tape.Link gear 11 is connected to Shaft 21 clump weights 19 by axle sleeve and circular nut and by axle sleeve and key, is connected to Shaft 21, integral-rack 10 both sides.Catch gear 14 bolts are connected on lower longeron 18; Testing agency 20 is connected on lower longeron 18 by spring shaft, is close to all the time the bottom of adhesive tape, and release mechanism 13 is connected on testing agency's 20 axles by bearing and axle sleeve.
When belt phenomenon occurs, testing agency's 20 antiports, driving simultaneously release mechanism 13 rotates, when reaching the setting number of turns, release mechanism 13 is opened catch gear 14, support rotating beam 3 under the effect of clump weight 19 gravity, around Shaft 21 rotations, and drive the upper rotating beam 5 of pressing around upper S. A. 23 rotations by link gear 11, adhesive tape 7 is clipped in and supports rotating beam 3, between upper pressure rotating beam 5, rely on adhesive tape 7, lower surface and support rotating beam 3, powerful friction brake force between upper pressure rotating beam 5, little by little the adhesive tape of downslide 7 is stopped, thereby reach the purpose that reduces economic loss and social influence.Support rotating beam 3 and be respectively equipped with skid resistant course with the outer face of upper pressure rotating beam 5, strengthened coefficient of friction, protective tapes is not damaged simultaneously.
