Abstract
The utility model discloses a claw-type backstop of an inclined belt conveyor, which belongs to the technical field of reversion resisting of the inclined belt conveyor and aims at overcoming the shortcomings that the existing backstop adopted by the inclined belt conveyor is not high in braking reliability. The claw-type backstop of the inclined belt conveyor comprises a machine frame and is provided with a fixing ring and a star wheel, the fixing ring is fixedly installed on the machine frame, more than one locking claw is installed in an inner cavity of the fixing ring in rotating mode, and reset springs are installed between the locking claws and the fixing ring. A central shaft is fixedly installed at the center of the star wheel, tow ends of the central shaft extend out of end covers through bearing holes on the end covers arranged on two sides of the fixing ring and both can be connected with other rotating parts, and at least one locking tooth is arranged on the star wheel. The claw-type backstop of the inclined belt conveyor is suitable for inclined belt conveyors.
Description
Technical field
The utility model relates to a kind of anti-reverse technology of the belt conveyer that tilts, and particularly involves in a kind of inclination belt conveyer pawl formula holdback.
Background technology
Belt conveyer is that a closed annular load-transfer device is walked around, is tensioned to simultaneously on the forward and backward roller, utilizes the rotation of roller to drive the load-transfer device continuous movement.Because belt conveyer has: simple in structure, easily manufactured, cheap; Comformability is strong aspect the material kind of route layout of carrying and conveying, the distance of conveying, speed height, and unit consumption of energy is lower; In course of conveying, the mode of operation balance can not damaged advantages such as being transferred material.So belt conveyer becomes a kind of material handling machinery that is extensively adopted by many industries.In various types of belt conveyers, there is load-transfer device greatly to be obliquely installed, purpose is in order to be delivered to a high position to material from low level.When the inclination belt conveyer was shut down, under the effect of material load and driving component deadweight, conveyer can produce antiport, accident such as caused low level loading place material to overflow to loose easily.In order to prevent that belt conveyer reverses when shutting down, generally all be provided with non-return device.Use and to the investigation of the non-return device of all kinds of inclination belt conveyers, find the present holdback that adopts with the mode of drift ping or the mode of band-type brake according to actual, essence all is to utilize friction force to prevent the generation of conveyer reversing when shutting down.Because the generation of friction force is not weighed fixed very much, the size variation amplitude of strength is very big.As: longer at the device period of service, friction face used during smoother, when friction face speckles with water, liquid, greasy dirt; Bigger in the conveyer degree of dip, when the material load is heavier; Be used for preventing the friction force of reversing can be very little.So present holdback can't prevent conveyer when shutting down, to reverse effectively, has the not high deficiency of reliability.
Summary of the invention
The purpose of the utility model provides a kind of inclination belt conveyer pawl formula holdback, overcomes the holdback that present inclination belt conveyer is adopted, the not high deficiency of braking reliability.
The utility model is achieved through following technical proposals.
The utility model comprises frame, is provided with mounting ring and star-wheel, and said mounting ring fixedly is loaded on the said frame, in the inner chamber of said mounting ring an above retaining pawl is housed rotationally, between said retaining pawl and the said mounting ring reset tension spring is housed; The center fixation of said star-wheel is equipped with center shaft, two ends of said center shaft through the bearing hole on the end cap of being located at said mounting ring two limits stretch in end cap the outside, and all can be connected with other rotatable parts, said star-wheel is provided with at least one stop tooth.In the design of the utility model, said center shaft is stretched in two outer ends of said end cap and can be connected with other rotatable parts, and said other rotatable parts can be the axis of forward and backward roller.As long as two ends of the said center shaft of transposing just can change the utility model and prevent the direction of rotating.When the utility model did not play brake action, by the said star-wheel rotation of external movement means, said retaining pawl slipped at the back side of said stop tooth gently, and the power that is consumed is atomic.In case the utility model plays brake action, then prop up the stop surface of said stop tooth by said retaining pawl, produce great braking force.
For at non-glancing impact, make have between the littler and glancing impact blade tooth of friction force between said retaining pawl and the stop tooth long-pending than large contact surface: the stop surface that the pawl end of said retaining pawl is equipped with roller and said stop tooth is provided with arc groove.
Against existing technologies, the beneficial effect of the utility model is:
Reliable operation, check power are big, have significantly improved the safety in operation of inclination belt conveyer.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is the A-A cutaway view of Fig. 1.Among the figure: 1, frame, 2, mounting ring, 3, star-wheel, 4, retaining pawl, 5, center shaft, 6, end cap, 7, stop tooth, 8, reset tension spring, 9, roller.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
As shown in the figure, the utility model is being made and during assembling, for the centre hole of mounting ring 2, star-wheel 3, center shaft 5 and end cap 6 good right alignment must be arranged, and simultaneously, should meet the codes and standards of associated mechanical parts; The assembling of retaining pawl 4, roller 9 and reset tension spring 8 also should meet the codes and standards of associated mechanical parts.After the utility model assembled, in the present embodiment, after an end of center shaft 5 and the axis of rear roller are connected, at last mounting ring 2 is fixed on the frame 1.In the present embodiment, when the running of the normal convey materials of conveyer, star-wheel 3 clickwises, retaining pawl 4 rolls across stop tooth 7 through roller 9 under the pulling and supporting of reset tension spring 8, the rotation of star-wheel 3 is had no effect; In case conveyer is shut down; The axis of roller can produce left-hand revolution; Also drive simultaneously star-wheel 3 left-hand revolutions, at this moment retaining pawl 4 can be immediately props up in the arc groove of the stop surface of stop tooth 7 through roller 9, with great dynamics, prevent the anticlockwise direction rotation of star-wheel 3 reliably; The generation of reversing when certainly, also just successfully having realized preventing conveyer to shut down.
