Abstract
The utility model discloses a chain rupture protector, including the casing, the casing internal rotation is connected with the pivot, and the fixedly connected with pendulum rod is gone back to fixedly connected with weight in the pivot in the pivot, still be equipped with the stopper that is used for restricting the pendulum rod shift position in the casing. The utility model adopts the above technical scheme, can detect and carry the chain whether to break off.
Description
Technical field
The utility model relates to pipe chain conveyer technical field, relates to a kind of break chain protector specifically.
Background technology
Pipe chain conveyer is the continuous conveying equipment of the bulk material such as conveying powdered, fine granularity and little bulk, can level, inclination and vertical cartel conveying.In closed conduit, with chain sheet for transmission component drives material along pipe motion.When horizontal feed, material particles is subject to the thrust of chain sheet at sense of motion.When internal friction when between the bed of material is greater than the external friction power of material and tube wall, material just travels forward with chain sheet, forms stable stream; When vertical transport, in pipe, material particles is subject to chain sheet to lifting force, because bottom feed stops top supports for material down-sliding, create cross side pressure, so enhance the internal friction of material, when the internal friction of storeroom be greater than material and inside pipe wall external friction power and material conduct oneself with dignity time, material is just upwards carried with chain sheet, forms continuous stream.
After existing pipe chain conveyor chain fracture, if can not be monitored in time, head box still operates, and not only affects production efficiency, and causes the waste of resource, and meanwhile, chain breakage rear motor dallies, and easily causes device damage.
Summary of the invention
The technical problems to be solved in the utility model provides one to have chain rupture for overcoming above-mentioned technical matters
The break chain protector of defencive function.
For solving the problem, the utility model by the following technical solutions: a kind of break chain protector, comprises housing; rotating shaft is rotatably connected in housing; rotating shaft being fixedly connected with weight, rotating shaft is also fixedly connected with fork, in housing, being also provided with the limiting stopper for limiting fork shift position.
Below further improvement of the utility model:
Position near weight in described housing is provided with inductor.
Further improvement:
Angle between described weight and fork is 30-80 °.
Whether the utility model adopts technique scheme, can detect chain and disconnect.
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In figure: 1-housing; 2-rotating shaft; 3-limiting stopper; 4-fork; 5-weight; 6-inductor; A-conveyer housing; B-chain; C-scrapes charging tray; D-opening.
Detailed description of the invention
Embodiment, as shown in Figure 1, a kind of break chain protector, comprises housing 1, is rotatably connected to rotating shaft 2 in housing 1, rotating shaft 2 is fixedly connected with weight 5, and rotating shaft 2 is also fixedly connected with fork 4, is also provided with the limiting stopper 3 for limiting fork 4 shift position in housing 1.
Inductor 6 is provided with near the position of weight 5 in described housing 1.
Angle between described weight 5 and fork 4 is α, α=30-80 °, preferably 60 °.
During installation, the conveyer housing a of pipe chain conveyer offers opening d, housing 1 is fixed on opening d place, fork 4 is deep in conveyer housing a, weight 5 naturally droops by self gravitation, chain d drives and scrapes charging tray c and move, scrape charging tray c drive fork 4 to turn an angle after fork 4 self-return, each charging tray c that scrapes drives through fork 4 place and scrapes charging tray c rotation once.
