Abstract
The invention relates to an electromagnetic brake backstop for an electric drum-type direct-drive belt conveyer and belongs to the field of electromagnetic technique. In the product design scheme, the electromagnetic technique is effectively introduced into mechanical design, an electromagnetic valve technique is used for replacing a complex mechanical brake and backstop structure and thus the product stability is improved. The electromagnetic brake backstop for the electric drum-type direct-drive belt conveyer is characterized in that a brake and a backstop of a drum are designed to an electrically controlled brake backstop through the working principle of a direct drive type electromagnetic valve. The design scheme has the following key point: by powering on and off the electromagnetic valve, electromagnetic force is generated to eliminate the characteristic of electromagnetic force; the lever principle is combined with the electromagnetic valve to produce a brake contracting effect; bolts and a backstop disc are combined with the electromagnetic valve to produce a backstop effect; two valve bodies are integrated in one box body to form the electromagnetic brake backstop for the electric drum-type direct-drive belt conveyer with braking and backstopping functions. The electromagnetic brake backstop for the electric drum-type direct-drive belt conveyer is mainly applied to the braking and backstopping of belt conveying equipment in places such as coal mines, wharfs, warehouses and long-distance conveying places.
Description
Technical field
This patent relates to the lever principle of machinery, belongs to electromagnetic technology field.
Background technology
Drg and the holdback of current drum belt conveyer separate, bulky very heavy.Drg and holdback are designed to one by this patent exactly.Adopt electromagnetic valve action to complete function, make mechanism compacter, save complete engine set installation space.
Summary of the invention
This is a kind of electromagnetic braking holdback, and it comprises: electromagnetic valve (1), leverage (2), spring (3), friction lining (4), electromagnetic valve (5), spring spool (6), pellet (7), casing (8), braking check dish (9), power transmission line (10).From Fig. 1, with roller end cover the braking check dish (9) closed, dish processes drag friction ring feature (see figure 3) and check dish upper groove feature (see figure 2).Band-type brake is carried out in Fig. 3 drag friction ring portion position.When reversing occurs cylinder, pellet (7) pushes in Fig. 2 indication groove and completes check by electromagnetic valve (5).The valve body of braking and check is bolted in casing (8), and braking valve body is arranged vertically, and check valve case horizontal arrangement, power transmission line (10) is drawn from casing lower end.We are for drum belt conveyer breaks and contrary stops.When needs cylinder stops operating, magnet coil energising in electromagnetic valve, band-type brake plays brake action.When cylinder rotates again, magnet coil power-off, friction lining and dynamic friction ring depart from, and cancel braking.Cylinder is when rotating, and the magnet coil of the electromagnetic valve of check unit is in electriferous state, does not play non-return effect.When cylinder stops operating, magnet coil is without electricity; Or during system cut-off, when magnet coil is without electricity, pellet pushes in check dish by spring iron core in electromagnetic valve, play non-return effect.
Accompanying drawing illustrates: Fig. 1 is that motorized pulleys directly drive band conveyor electromagnetic braking backstop and always scheme; Fig. 2 is stop check dish front view; Fig. 3 is the partial enlarged drawing of the total figure of braking backstop.
Claims (3)
1. an electric roller type directly drives band conveyor electromagnetic braking holdback, comprise brake unit and check unit, brake unit: electromagnetic valve (1), leverage (2), spring (3), friction lining (4), magnet coil energising in electromagnetic valve (1) produces electromagnetic force, iron core is lifted together with leverage (2) one end, leverage (2) other end is by Friction disk (4) and braking check dish (9) band-type brake, and spring (3) is in extended state; By magnet coil power-off in electromagnetic valve (1), spring (3) shrinks, and is depressed by iron core, and because of leverage (2) effect, friction lining (4) separates with braking check dish (9); Check unit: electromagnetic valve (5), spring iron core (6), pellet (7), electromagnetic valve (5) is in electriferous state at ordinary times, the spring of the spring iron core (6) in valve body is in compressive state, electromagnetic valve (5) dead electricity, pellet (7) is pushed into check dish (see figure 2) bottom portion of groove by the elastic force of spring iron core (6), stops cylinder reversing.
2. as claimed in claim 1, the feature of brake unit is, electromagnetic valve (1) energising produces electromagnetic force, acts on leverage (2), completes band-type brake action.
3. as claimed in claim 1, check element characteristic is, electromagnetic valve (5) power-off, and spring spool (6) promotes pellet (7) and enters check dish groove (Fig. 2), plays non-return effect; When cylinder restarts, electromagnetic valve (5) is energized, and pellet (7) pushes back by check dish inclined-plane.
