With reference to a kind of belt conveyer weight 5 formula belt break protection device shown in accompanying drawing 1-3, comprise the side stand 1 in conveyer both sides arranged in parallel, the side of two side stands 1 is all connected with some digonal links 6, two described side stands 1 upper, in, lower part is equipped with top cross-bar, intermediate transverse girder and braking crossbeam 12, described top cross-bar is provided with flame-proof type travel switch 9, it is characterized in that: also comprise lower flip beam 3, upper flip beam 8, rotating beam 11 arrested by lower belt, lower flip beam catch gear 18, rotating beam catch gear 19 arrested by lower belt, weight 5 and fork 10, the two ends that rotating beam 11 three arrested by described lower flip beam 3, lower flip beam catch gear 18 and described lower belt are all arranged between the intermediate transverse girder on two side stands 1 by bearing seat 1, and described lower flip beam catch gear 18 is positioned at the midway location that rotating beam 11 arrested by described lower flip beam 3 and lower belt, described upper flip beam 8 two ends are arranged between the top cross-bar on two side stands 1 by bearing seat 2 24, on two described side stands 1 the same side described on be all articulated and connected by connecting rod 7 between flip beam 8 and lower flip beam 3, be connected in coupling type between described lower flip beam 3 with described lower flip beam catch gear 18, described lower belt is arrested rotating beam catch gear 19 and is arranged on one end that rotating beam 11 arrested by described lower belt, and described fork 10 lower end and lower belt are arrested rotating beam 11 coupling type and be connected, and upper end is connected with upper flip beam 8, the two ends of described lower flip beam 3 are all connected with swing arm 21 screw threads for fastening by described key cover 22, and in each described swing arm 21, arrange described weight 5, two weight 5 rotate up lower flip beam 3 and provide power, ensure section belt jack-up to flatten.
Further, described lower flip beam catch gear 18 comprises the roller 2 that tests the speed, shank of the key 4, fifth wheel 17 and driving device 23.
Further, be connected in coupling type by described shank of the key 4 between described lower flip beam 3 with described lower flip beam catch gear 18, described fifth wheel 17 to test the speed the wherein end of roller 2 described in being located at, and described fifth wheel 17 is connected with roller 2 key that tests the speed, described fifth wheel 17 is in transmission connection with described driving device 23, the roller 2 that tests the speed detects epithelium tape running state in real time, flutters catch broken belt signal for catch brake is accurate.
Further, described lower flip beam 3 top is provided with lower friction plate 14 and is hinged and connected with it, and insurance carrying roller 13 is also housed in described lower flip beam 3 side.
Further, regulating plate 16 is equipped with at described upper flip beam 8 top, the upper friction plate 15 hinged with it is provided with on described bottom flip beam 8, described upper flip beam 8 bottom and upper friction plate 15 are hinged and connected, regulating plate 16 is equipped with at top, be threaded between regulating plate 16 with the main body of upper flip beam 8, the lower friction plate 14 of convenient adjustment and upper friction plate 15 gap, ensure enough friction brake force; Upper flip beam 8 is once be rotated down, and flame-proof type travel switch 9 action, conveyer power supply is cut off immediately, guarantees that safety avoids secondary fault to occur.
The utility model must not implement catch brake to belt for guaranteeing when belt normally runs, and devises Liang Zhong mechanism to ensure, i.e. described lower flip beam catch gear 18 and described insurance carrying roller 13.
Concrete implementation process is:
Before belt is not disconnected: as shown in Figure 1, when belt normally runs (belt disconnected before), the roller 2 that tests the speed in lower flip beam catch gear 18 runs with belt and rotates, real-time detection belt running state, the fifth wheel 17 then non rotating be connected with the roller 2 that tests the speed, shank of the key 4 can not be opened, lower flip beam 3 is pinned at level attitude always, it is stoped upwards to overturn, be hinged and connected by connecting rod 7 between upper flip beam 8 and lower flip beam 3, also prevent flip beam 8 to overturn downwards simultaneously, upper flip beam 8 is failure to actuate, fork 10 in rotating beam catch gear 19 arrested by the lower belt be connected with upper flip beam 8 also can not action, fork 10 just pins lower belt always and arrests rotating beam 11, it is stoped to overturn downwards.
After belt broken belt: upper belt loses tensile force, accelerate to glide under self gravitation effect, now go up belt sense of motion contrary with direction when normally running, test the speed roller 2 with belt contrarotation, the fifth wheel 17 be connected with the roller 2 that tests the speed then rotates thereupon, after fifth wheel 17 forwards preset distance to, drive transmission 23 promotes shank of the key 4 Unscrew, lower flip beam 3 is unlocked, rotate up by level attitude under the Action of Gravity Field of two weights 5, owing to being hinged and connected by connecting rod 7 between upper flip beam 8 and lower flip beam 3, upper flip beam 8 is also rotated down thereupon, gravitational moment suffered by upper flip beam 8 and belt downslide friction moment are respectively flip beam 8 and lower flip beam 3 provides positive energy, rotate and accelerate, quick action lock torque is large, while upper flip beam 8 has spinning movement (i.e. cAN _ SNture), first the action of flame-proof type travel switch 9 is triggered, conveyer power supply is cut off immediately, and conveyer power down is shut down, meanwhile, the fork 10 that under upper flip beam 8 drags, belt is arrested in rotating beam catch gear 19 rotates, lower belt is arrested rotating beam 11 and is unlocked, and the gravitational moment effect by self is rotated down, and is pressed in by hypodermis band on braking crossbeam 12, so far cAN _ SNture completes, and forces the upper and lower belt of having no progeny to stop, during reset, manually two weights 5 are raised to reference position, hand rotation fifth wheel 17, shank of the key 4 and lower flip beam 3 are linked and connects, lower flip beam 3 and upper flip beam 8 reset complete, lower belt is arrested rotating beam 11 manual rotation and fork 10 and is linked and connect, and lower belt is arrested rotating beam 11 and is namely reset, the state before the utility model returns to and arrests.
Insurance carrying roller 13 is made of one with lower flip beam 3, and itself is free to rotate, and when lower flip beam catch gear 18 lost efficacy, can also ensure that the utility model is implemented correctly to arrest, be guarantee safe second defence line; Itself there is tensile force before belt is not disconnected, upper belt is tightly pushed down on the insurance carrying roller 13 of lower flip beam 3 sidepiece, thus prevents lower flip beam 3 upwards to overturn, and cAN _ SNture can not be completed.Therefore, as long as the tensile force of belt exists, disconnected fender guard can not produce any braking by mistake, when belt is had no progeny and arrested and reset effective with lower flip beam catch gear 18.
The beneficial effects of the utility model are: by arranging weight, provide power for arresting broken belt, and retro-speed is fast, and friction brake force is large, and its structure is simple, and do not need to safeguard, cost is extremely low; Lower flip beam catch gear with the roller that tests the speed, uninterrupted sampling belt run signal, detected broken belt signal is more true and reliable compared with prior art, long service life, and operating cost is low; When upper belt is by catch brake, with flame-proof type travel switch to be triggered connection, can reliably stop conveyer power supply, avoid secondary accident to occur, meanwhile, lower belt is arrested rotating beam catch gear and is opened, and lower belt is also braked; It can not damage by the huge inertia impact of belt, also can not damage belt and the frame of conveyer, have structure simple, catch brake power is large, cheap, is that a kind of degree of automation is higher, not only safety but also failure-free full-section belt fender guard.
