The technical measures of optimizing are:
For increasing the friction force with brake wheel, auxilliary rope is walked around brake wheel and is at least a circle, and should assist end through regulating control connecting bridge railway carriage or compartment.By adjusting, to regulate the elasticity of auxilliary rope to cable regulator.
The below of slotted hole is provided with the safety switch that is installed on the rack side plate, is positioned at the brake axle butt safety switch of slotted hole bottom.Touched safety switch when brake axle moves down into the below of slotted hole, safety switch cuts off the power supply of elevator and finishes protection process.
Spring is fitted with the adjusting bolt of the stopping distance that is used to regulate the objective of defense.By adjusting two adjusting bolts on the spring, the intensity of spring and the stopping distance of the objective of defense are adapted.
Compared with prior art, the utility model support has on two side plates and has slotted hole, and this slotted hole is put the two ends of the brake axle that is fitted with brake wheel, makes the two ends of brake axle can be in the slotted hole upper and lower displacement; Add auxilliary rope between bridge railway carriage or compartment and the counterweight, this auxilliary rope is walked around brake wheel and the track adjusting wheel of being located on day beam, and brake wheel is perpendicular to the bridge railway carriage or compartment, and track adjusting wheel is perpendicular to counterweight; Support biside plate inboard is welded with brake scotch respectively, and this brake scotch curves with the corresponding arc of brake wheel extrados, and brake wheel and brake scotch are keeping suitable spacing; The outside of support is fitted with spring respectively, and this spring line of centers is with the line of centers alignment of slotted hole, aligns with the lower surface of slotted hole in spring pipe upper surface.Elevator is under normal operation, auxilliary rope is the pressure that is not subjected to bridge railway carriage or compartment and counterweight of pine after adjusting, the two ends of brake axle to the upper end of slotted hole, make brake wheel and the brake scotch of being located at the brake wheel below keep suitable spacing by two spring tops, and brake equipment is not worked.When main fracture of rope, bearing pressure on the auxilliary rope from bridge railway carriage or compartment and counterweight, drive the bearing force that the downward pressure of brake axle has overcome spring, brake wheel is moved down, brake wheel contacts with brake scotch, brake equipment work, gradually with the brake wheel stop, brake wheel is by stop bridge railway carriage or compartment and the counterweight out of control gradually of the steel rope on the braking race.Touch safety switch when brake axle moves down, safety switch cuts off the power circuit of elevator and finishes the whole protection process.Can adjust the required distance of braking by the intensity of adjusting two springs to the objective of defense (bridge railway carriage or compartment and counterweight).
Description of drawings
Fig. 1 is the general illustration of the utility model embodiment.
Specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.Shown in Figure 1, the elevator gradual anti-falling safety device, the main rope 8 that comprises support 1, brake wheel 6, track adjusting wheel 10, setting fastening bridge railway carriage or compartment 12 and counterweight 11, support 1 is installed on the sky beam of elevator, support 1 has on two side plates that extend downwards and has slotted hole 2, the two ends that this slotted hole 2 is put the brake axle 3 that is fitted with brake wheel 6 make the two ends of brake axle can be in the slotted hole upper and lower displacement;
Add auxilliary rope 8 between bridge railway carriage or compartment 12 and the counterweight 11, this auxilliary rope 8 is walked around brake wheel 6 and the track adjusting wheel of being located on day beam 10, and brake wheel 6 is perpendicular to bridge railway carriage or compartment 12, and track adjusting wheel 10 is perpendicular to counterweight 11; Support 1 biside plate inboard is welded with brake scotch 7 respectively, and promptly brake scotch 7 is divided into two, and this brake scotch 7 curves with the corresponding arc of brake wheel 6 extrados, and brake wheel 6 and brake scotch 7 are keeping suitable spacing; Utilize the auxilliary rope of a steel rope as elevator, when elevator normally moves, it does not bear the gravity of the objective of defense such as bridge railway carriage or compartment, counterweight, when the objective of defense is out of control, it is under the effect of power out of control, pulling brake wheel and brake scotch force their closed contacts, and the braking force of brake wheel and brake scotch generation is passed to the objective of defense, make objective of defense stop out of control.
The outside of support 1 is fitted with spring 4 respectively, and these spring 4 line of centerss are with the line of centers alignment of slotted hole 2, aligns with the lower surface of slotted hole 2 in spring pipe upper surface.
For increasing the friction force with brake wheel 6, auxilliary rope 8 is walked around brake wheel 6 and is at least a circle, and should assist rope 8 ends through regulating control 9 connecting bridge railway carriage or compartments 12.By adjusting, to regulate the elasticity of auxilliary rope 8 to cable regulator 9.
The below of slotted hole 2 is provided with the safety switch 13 that is installed on support 1 side plate, is positioned at the brake axle 3 butt safety switchs 13 of slotted hole 2 bottoms.Touched safety switch 13 when brake axle 3 moves down into the below of slotted hole 2, the power supply that safety switch 13 cuts off elevator is finished protection process.
Elevator is when normal operation, and the weight of bridge railway carriage or compartment 12 and counterweight 11 all drops on the main rope 14.At this moment, the two ends of brake axle 3 are in the top of slotted hole 2 under the effect of two springs 4, brake wheel 6 and brake scotch 7 are keeping suitable spacing, auxilliary rope 8 is not subjected to the gravity of the objective of defense, and then objective of defense bridge railway carriage or compartment 12 and counterweight 11 operations, and safety is not worked.
When main rope 14 ruptured, the force of gravity of objective of defense bridge railway carriage or compartment 12 and counterweight 11 was come to auxilliary rope 8.Auxilliary rope 8 is passed to brake wheel 6 with downward gravity, and brake axle 3 has overcome the top power of spring 4 under the effect of downward gravity, move on to the below of slotted hole 2.Brake wheel 6 was pressed on and produced friction force above the brake scotch 7 this moment, and brake wheel 6 is gradually by the friction force stop, and brake wheel 6 is also passed to objective of defense bridge railway carriage or compartment 12 and counterweight 11 with braking force by auxilliary rope 8 simultaneously, with objective of defense stop.Touched safety switch 13 when brake axle 3 moves down into the below of slotted hole 2, the power supply that safety switch 13 cuts off elevator is finished protection process.
Though the utility model illustrates and describes by the reference preferred embodiment, but, those skilled in the art should understand, under the situation of the spirit and scope of the present utility model that do not deviate from accompanying Claim and limited, can carry out various variations in form and details.
