Be applicable to that the elevator is prevented exceeding the speed limit, is prevented falling, scour protection top, the end of preventing squatting, prevent the swift current ladder, prevent the open by mistake machine, prevent general -purpose safety arrangement such as open by mistake door.

Description

Vertical lift elevator multi-purpose bidirectional Electromgnetic seat clamps

Technical field

This utility model relates to the safety guard of a kind of vertical lift elevator.

Background technology

At present, in the safety guard of existing vertical lift elevator, anti-hypervelocity, the safety tongs of falling-proof safety device are mechanical type, There is the shortcomings such as sensitivity is low, response speed is slow, it can only control its protection act by the mechanical linkage mode of limiter of speed, And protection content is single, can only act on that unidirectional anti-hypervelocity made by guide rail, fall arrest protection is used, it is impossible to expand to other protections and use On the way.

Summary of the invention

For the deficiency overcoming the anti-hypervelocity of existing elevator, falling-proof safety device to exist, this utility model provides a kind of vertical lift Elevator multi-purpose bidirectional Electromgnetic seat clamps, this Electromgnetic seat pincers for electromechanical, have highly sensitive, response speed fast, protection purposes Extensively, can act on guide rail and the features such as bidirectional protective made by hoist ropes, it is under the control circuit with respective control function controls, energy Realize the defencive functions such as the deceleration stop to car multiple use.

It is to be protected to control it by control circuit that this utility model solves the technical scheme is that this utility model of its technical problem Protect action, use the electromagnetic force that electric magnet produces as the power of safety tongs action, utilize bi-directional braking structure, by electromagnetic force Effect, sends into bi-directional braking element between clamp block and guide rail or hoist ropes so that it is contact with guide rail or hoist ropes and rub, wherein There is direction produced by side's braking member identical with guide rail or the hoist ropes direction of motion, utilize clamp block and guide rail or traction The angle effect formed between rope, or utilize the eccentric motion effect of eccentric detent element, make this braking member and guide rail or hoist ropes it Between form more motion, guide rail or hoist ropes are braked element and hold the tightest, the effect that frictional force is the biggest, the frictional force produced with it, Consume elevator kinetic energy, by car stop by force；Because of frictional force produced between braking member and guide rail or the hoist ropes of the opposing party and Guide rail or the hoist ropes direction of motion are contrary, therefore this braking member does not works.In like manner, when car moves round about, the opposing party's Braking member works, and by car stop by force, thus reaches the protection purpose of two-way for car deceleration stop.

The beneficial effects of the utility model are: upgraded to this practicality by the anti-hypervelocity of existing elevator, the mechanical safety device of fall arrest Novel electromechanical safety device, it has, and highly sensitive, response speed is fast, protection purposes is wide, can act on guide rail and traction Rope make the features such as bidirectional protective, it is adaptable at the bottom of the anti-hypervelocity of elevator, fall arrest, preventing colliding with top, anti-crouching, anti-slip ladder, anti-error start, The safety guard of the multiple uses such as anti-error enabling.

Detailed description of the invention

In this utility model, brake structure, one side brake structure pattern or double-sided braking structural shape can be used；Braking member, can Use longitudinally single or multiple patterns.

In this utility model, the contact surface of braking member Yu hoist ropes can be made the matrix matched.

This safety tongs can be separately mounted to the appropriate location, the left and right sides of car cab or pair weight, match with two, left and right guide rail； Maybe this safety tongs is arranged on traction machine or other are near the appropriate location of hoist ropes, match with hoist ropes, as shown in Figure 1, Figure 2, Shown in Fig. 3.

In Fig. 1, Fig. 2, embodiment illustrated in fig. 3, after solenoid (1) is energized, under the effect of electromagnetic force (P), upper and lower two Individual electromagnetic core (2) adhesive, is applied to electromagnetic force (P) on upper and lower two lever arms (3), by upper and lower two lever arms (3) simultaneously Bi-directional braking element is respectively fed between the clamp block (7) of upper and lower both direction and guide rail or hoist ropes (8) so that it is with guide rail or drag Messenger (8) contacts and rubs, and when guide rail or hoist ropes (8) move upward relative to clamp block (7), the braking member (6) of top is because of institute The direction produced is identical with guide rail or hoist ropes (8) direction of motion, in (in Fig. 1, Fig. 2) clamp block (7) and guide rail or traction Under the angle effect formed between rope (8), or under the eccentric motion effect of (in Fig. 3) eccentric detent element (6), make this braking unit More motion, the result that frictional force is the biggest, at last car stop by force is formed between part (6) and guide rail or hoist ropes (8)；Because of lower section Braking member (6) frictional force produced with between guide rail or hoist ropes (8) and guide rail or hoist ropes (8) direction of motion contrary, therefore This braking member (6) does not works.In like manner, when guide rail or hoist ropes (8) move downward relative to clamp block (7), the braking member of lower section (6) work, by car stop by force, thus reaches the protection purpose of two-way for car deceleration stop.When after solenoid (1) power-off, Braking member (6), under the effect of angle or bias and under the effect of car or counterweight, still suffers from the frictional force of energy stop car, therefore Car, still by stop, only recovers to do adverse movement by machine room, and under the effect of back-moving spring (4), braking member (6) resets, sedan-chair Railway carriage or compartment recovers normal.

In Fig. 1, Fig. 2, embodiment illustrated in fig. 3, such as the symmetrical one side at one side brake structure, replicate same symmetrical brake structure, Become the embodiment of another double-sided braking structural shape.
