Abstract
Safety protection device of a hanging rail type elevator. Relates to a safety protection device which is widely applied to goods vertical transportation machinery in departments of building construction, industrial and mining enterprises, warehouses, markets and the like. The utility model discloses utilize the tractive electromagnet to switch on in step with the lifting machine power and hang under the fence out of control state tractive electromagnet circuit by automatic cutout, make the safety hook that is fixed in on the hanging fence can break away from automatically or the hook is on the horizontal web member of pylon, the utility model has the advantages of simple structure, safe and reliable, easy operation, the department such as specially adapted building construction, industrial and mining enterprise, warehouse, market uses on the perpendicular transport machinery of goods.
Description
The utility model relates to the safety guard on a kind of vertical transportation machinery of the goods that is used for departments such as building operation, industrial and mining enterprises, warehouse, market.
As everyone knows; the goods vertical transportation machinery is in the operational process that promotes goods; in order to prevent to hang hurdle degeneration accident; generally adopt fall frame and hang and cross bar is set after the hurdle puts in place holds the method for hanging the hurdle of safety; but all can only play to hang and fixedly hang the unlikely degeneration in hurdle when the hurdle puts back loading and unloading material in place; if but the generation wire cable rupture that is in operation when mechanical breakdown such as plunging joint is malfunctioning and causing is hung hurdle degeneration accident out of control, then can not play the safety guard-safeguard effect.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of hanger style mine hoist safety fender guard is provided.
Principle of work of the present utility model is: when gig moves, when changing to hanging hurdle movable pulley application force, upper and lower moving in the axial trough of movable pulley axle on hanging hurdle movable pulley frame, make switch be in the closed type normally open, make the circuit of tractive magnet be switched on or cut off, thereby make safety hook break away from or tangle the horizontal web member of pylon, reach purpose fixing at an arbitrary position or that the hurdle is hung in lifting.
The utlity model has simple in structure, safe and reliable, processing ease, advantage such as cheap is particularly suitable for the uses of department on the goods vertical transportation machinery such as building operation, industrial and mining enterprises, warehouse, market.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model front view
Accompanying drawing 2 is for hanging hurdle movable pulley parts (4) front view
Accompanying drawing 3 is for hanging hurdle movable pulley parts (4) lateral plan
Accompanying drawing 4 is safety hook parts (11) constructionals drawing
Accompanying drawing 5 is the utility model electrical schematic diagram
See accompanying drawing, the utility model is by steel rope (1), steel rope fixed pulley (2), (3), hang hurdle movable pulley parts (4), cable fixed pulley (5), (6), cable movable pulley (7), clump weight (8), cable (9), tractive magnet (10), safety hook parts (11), switch (13), electromagnet connecting rod (20), hang hurdle (23) and form pylon (22).Hang hurdle movable pulley parts (4) by pulley retracing spring (15), spring born work arbor (17), sheave shaft (18), hang hurdle movable pulley frame (19), hanging hurdle movable pulley (24) forms, safety hook parts (11) are by hook bearing pin (12), link up with the torque spring (14) that resets, hook pipe link (16), safety hook (21) is formed, hanging hurdle movable pulley frame (19) is fixed in and hangs on the hurdle (23), sheave shaft (18) is fixed on the steel rope movable pulley (24), and its two ends are set in the axial trough that hangs hurdle movable pulley frame (19) that has axial trough, switch (13) is loaded on an end of steel rope movable pulley frame (19) axial trough, spring born work arbor (17) upper sleeve through has pulley retracing spring (15), and one is passed movable pulley axle (18) and fixes on it.The other end is passed and is hung hurdle movable pulley frame (19) cover plate, the pedestal of hook bearing pin (12) is fixed in and hangs on the hurdle (23), linking up with the torque spring (14) that resets is set on the hook bearing pin (12), and one is hooked on the hook pipe link (16) that is fixed between the safety hook (21), the other end is hooked on the pedestal of hook bearing pin (12), tractive magnet (10) is fixed on and hangs on the hurdle (23), electromagnet connecting rod (20) one ends on it are connected with hook pipe link (16), switch (13) is serially connected with in the circuit of tractive magnet (10), and tractive magnet (10) is connected on the gig circuit.
Steel rope fixed pulley (2), (3), pylon (22) top all is fixed in cable fixed pulley (5), (6), cable (9) is walked around cable fixed pulley (5), (6), and its sagging closing end is hung with cable movable pulley (7), is hung with clump weight (8) on cable movable pulley (7).
When using the utility model, gig starts, steel rope (1) is by steel rope fixed pulley (2), (3) produce pulling force upwards to hanging hurdle movable pulley (24), sheave shaft (18) is together with spring born work arbor (17) upward movement, and compression pulley retracing spring (15), make sheave shaft (18) be in the axial trough top dead center position that hangs on the hurdle movable pulley frame (19), switch (13) resets and is in closure state, the circuit of tractive magnet (10) is connected, the safety hook (21) that produces tractive force and tangle on the horizontal web member of pylon (22) by electromagnet connecting rod (20) pulling leaves its original position, hangs hurdle (23) and gets final product, following operation.
After gig puts in place, cut off the gig power supply, tractive magnet (10) power supply also is cut off, tractive force disappears, safety hook (21) is under hook resets the effect of torque spring (14), be flapped toward pylon (22) rapidly, hang on the horizontal web member of pylon (22), in case hang hurdle (23) degeneration.
When hanging hurdle (23) degeneration out of control because of mechanical breakdown, steel rope (1) will significantly reduce or disappear to the pulling force that hangs hurdle movable pulley (24), sheave shaft (18) is under the pressure effect of pulley retracing spring (15), rapidly to the axial trough bottom dead point motion of hanging on the hurdle movable pulley frame (19), and by spring born work arbor (17) the termination pressing switch (13) that is connected on the sheave shaft (18), make switch (13) be in normally open, in like manner, tractive force disappears, safety hook (21) is under hook resets the effect of torque spring (14), tangle rapidly on the horizontal web member of pylon (22), fixedly hang hurdle (23), make it no longer to degenerate.
When the gig lifting, walk around the cable (9) of cable fixed pulley (5), (6) and go up under suspension clump weight (8) effect at cable movable pulley (7), can keep cable (9) and gig synchronization lifting.
