Abstract
The utility model discloses a safety protection device of a round pipe type belt conveyor, relates to a conveying device and aims at providing the safety protection device of the round pipe type belt conveyor, which can prevent a conveyor belt and supporting rollers from being damaged. The technical scheme is as follows: the safety protection device comprises a mast and a regular hexagonal supporting roller group, plates for fixing the supporting roller group comprises a lower plate and an upper swing plate which are mutually separated, three supporting rollers of the regular hexagonal supporting roller group are fixed on the upper swing plate, horizontal threaded holes are respectively arranged on the mast which is opposite to the left side wall and the right side wall of the upper swing plate, and matched with screws, damping blocks are connected at the ends of the screws, and the upper end of the upper swing plate is hinged with the top part of the mast, and a proximity switch is arranged on the left or the right side wall of the mast. The safety protection device of the round pipe type belt conveyor is used for conveying bulk materials.
Description
Technical field:
The utility model relates to the safety guard of a kind of load transfer device, particularly a kind of circular pipe belt type conveyer.
Background technology:
The circular pipe type conveyer is a kind of bulk material handling equipment free from environmental pollution, and this conveyer is to force that by the regular hexagon carrying roller load-transfer device is rolled into the cylindric material that will loose shape to wrap up conveying.The load-transfer device of the carrying afterbody transition phase of conveyer is the flute profile band, and material is thrown thereon, progressively is forced to be rolled into the pipe shape then, when mass transport is located in to purpose, load-transfer device is progressively plane by generate, after material is laid down, is rolled into tubulose return conveyor afterbody again.Under the normal circumstances, the loading of material in pipe must not be greater than 80%, and maximum particle diameter must not be greater than 1/3 of caliber, when material particular diameter greater than caliber 2/3 the time, the loading of material must be reduced to 44%.But when conveyer was worked, it was inhomogeneous always can material loading to occur, perhaps had the material of big particle diameter to enter in the pipe, in case above situation takes place, the pipe that rises will appear, and cause load-transfer device and carrying roller group to be damaged, and involving great expense of this circular tube conveying belt in case be damaged, lost bigger.
Summary of the invention:
The purpose of this utility model provides a kind of safety guard that prevents the circular pipe belt type conveyer that load-transfer device and carrying roller damage.The technical solution of the utility model is, include door frame and orthohexagonal carrying roller group, it is characterized in that: fixedly the plate of carrying roller group is upper and lower two lower plates that are separated from each other and last pendulum plate, three carrying rollers of orthohexagonal carrying roller group are fixed on the pendulum plate, with on be respectively equipped with horizontal tapped bore on the relative door frame of pendulum plate left and right sides wall and screw matches, termination at screw is connected with damping block, on to put the top of the upper end of plate and door frame hinged, be provided with near switch at a left side or the right side wall place of door frame.The utility model has the not impaired advantage of load-transfer device compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of anti-tube-expanding device of the present utility model.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, can not surpass regulation and be risen bad or the carrying roller damage in order to ensure circular tube conveying belt because of the interior inventory of big particle diameter material or pipe takes place in the pipe, first trustship group after load-transfer device is forced to be rolled into pipe, make following structure, the fixing plate of carrying roller group 4 is divided into, following two plates, wherein fixedly the pendulum plate 2 of three of top carrier roller frames is separated with the fixing plate 8 of three carrier roller frames of bottom, the top of wherein putting plate 2 is hinged by hinge 1 and door frame 3, on the door frame sidewall relative, be provided with damping block with the plate 2 of three carrying rollers above fixing, door frame and damping block are provided with the tapped bore that matches with screw 5, screw threads is gone in the tapped bore of door frame and damping block, is provided with near switch 6 in the side-walls of door frame.
The utility model prevents that the principle that circular tube conveying belt and carrying roller group are damaged from being, when the material particular diameter of carrying pipe band 7 or material charging quantity surpass when specified, because pipe expands, power between its when motion and the damper is greater than the specified resistance of damper, so pendulum plate 2 is swung backward, the pipe internal cavity is increased, thereby prevented the damage of pipe and carrying roller group, meanwhile, when the pendulum plate is put backward, near switch 6 actions load-transfer device is quit work, after material in managing is handled, can carry again.
Said structure can realize that circular tube conveying belt is because of big particle diameter material or too much load-transfer device and the carrying roller group damaged of material.
