Specific embodiment

Embodiment:As shown in figures 1-8, the utility model provides a kind of specific embodiment of brake device for elevator, its use In to steel wire rope 42 or guide rail bi-directional braking, including:At least one pair of fixing clip 10, fixture block 10 can be relatively fixed move back and forth simultaneously At least one pair of movable clip block 20, the drive mechanism 30 of the driving motion of movable clip block 20 and setting positioned at the both sides of steel wire rope 42 On movable clip block 20 and with the friction plate 50 of the CONTACT WITH FRICTION of steel wire rope 42, wherein that side is provided with first is oblique for fixing clip 10 Face 12 and a pair second inclined-planes 14 positioned at the both sides of the first inclined-plane 12, movable clip block 20 are provided with and the first inclined-plane in side 12 the 3rd inclined-planes 22 for coordinating and a pair the 4th inclined-planes 24 accordingly coordinated with corresponding second inclined-plane.Fixing clip 10 is another Side then with support spring (not shown) abutting contact, and the opposite side of movable clip block 20 is then provided with friction plate 50.First inclined-plane 12 Incline direction and the second inclined-plane 14 incline direction each other conversely, the 3rd incline direction on inclined-plane 22 and inclining for the 4th inclined-plane 24 Tilted direction is matched somebody with somebody conversely, thus entering line slip by the form of positive and negative lozenges between fixing clip 10 and movable clip block 20 each other Close, i.e., fixing clip 10 is provided with positive and negative lozenges, and movable clip block 20 is also correspondingly provided with positive and negative lozenges and is coordinated, The first inclined-plane 12 and the 4th inclined-plane 24 are positive lozenges in the present embodiment, wedge like convex portion, and the second inclined-plane 14 and the 3rd Inclined-plane 22 is anti-lozenges, wedge like groove.

Drive mechanism 30 includes connecting rod 36 and the connection of the upper and lower support and the upper and lower support of connection positioned at two ends Bar 36 is parallel and allows the connecting rod rotary shaft 37 for rotating against, drive the rotation of a connecting rod 36 swing rod 38, driving swing rod 38 The driver element 39 of rotation.Driver element 39 preferably uses electromagnet mode, similarly, driver element 39 in the present embodiment Can be electronic, hydraulic pressure, pneumatic unit.Support includes a pair first poles 32 being oppositely arranged and the corresponding hinge of the first pole 32 A pair second poles 34 for connecing and being oppositely arranged, the wherein center of connecting rod 36 are hinged with the first pole 32 and the second pole 34 Central coaxial, the number of connecting rod 36 is 4, and two connecting rods 36 of one pair of which linea angulata pass through movable clip block 20, and another Cornerwise two connecting rods 36 then it is exposed outside, the length of the second pole 34 more than the first pole 32 length, and first and second Pole 32,34 is collectively forming parallelogram frame, and is collectively forming for steel wire rope 42 with the friction plate 50 on movable clip block 20 The rope passage 40 of up-and-down movement.

As shown in figure 1, when initial, the 4th inclined-plane 24 of movable clip block 20 and the second inclined-plane 14 of fixing clip 10 are against matching somebody with somebody Close, and the 3rd inclined-plane 22 of movable clip block 20 is then located remotely from each other with the first inclined-plane 12 of fixing clip 10.

When car door is opened, controller signals to driver element 39, the dead electricity of driver element 39, and promotes swing rod 38 to revolve Turn, drive upper and lower support to perform pinching action, as shown in figure 4, the movable clip block 20 of the both sides of steel wire rope 42 is pressed from both sides towards steel wire rope 42 Tightly move, thus friction plate 50 and the abutting contact of steel wire rope 42.When there is unexpected moving up in steel wire rope 42, as shown in Fig. 2 Movable clip block 20 is also synchronous in the presence of frictional force up to be walked, and the of the 4th inclined-plane 24 of movable clip block 20 and fixing clip 10 Two inclined-planes 14 are gradually distance from cooperation, and first inclined-plane 12 of the 3rd inclined-plane 22 of movable clip block 20 then gradually with fixing clip 10 is supported By coordinating, thus there is interval in movable clip block 20 and fixing clip 10 in the horizontal direction, and movable clip block 20 is more up moved, and is rubbed Gap between pad 50 and steel wire rope 42 is smaller, and frictional force is bigger, thus the friction plate 50 of movable clip block 20 and steel wire rope 42 Between produce Self-locking angle, realize self-locking, it is ensured that car safety stop;When steel wire rope 42 occurs unexpected moving down, such as Fig. 3 institutes Show, the 4th inclined-plane 24 of movable clip block 20 and the second inclined-plane 14 of fixing clip 10 are moved downward with merging, and movable clip block 20 The 3rd inclined-plane 22 then continue away from the cooperation with the first inclined-plane 12 of fixing clip 10, movable clip block 20 more moves down, and rubs Gap between pad 50 and steel wire rope 42 is smaller, and frictional force is bigger, thus the friction plate 50 of movable clip block 20 and steel wire rope 42 Between produce Self-locking angle, realize self-locking, it is ensured that car safety is stopped, so also avoid in existing structure from starting just to be produced from Lock, it is desirable to which spring dynamics is larger, and required power of electromagnet is larger.And when car door is closed, controller is transmitted Number give driver element 39, driver element 39 it is electric, upper and lower support performs expansion action, as shown in figure 5, friction plate 50 and steel wire Rope 42 is disengaged, and steel wire rope 42 recovers normal operating condition, and car normally moves up and down.

Because the utility model uses above-mentioned technical proposal, with advantages below:

1st, coordinate to realize bi-directional braking and the realization of steel wire rope using the positive and negative lozenges of fixing clip and movable clip block Self-locking, to reach the purpose of braking, it is to avoid Safe Failure, reduces the serious accident of casualties.

2nd, movable clip block is kept clamp position under electromagnet effect, and once after Power resumption, can voluntarily release work Dynamic fixture block makes steel wire rope recover normal operating condition the clamp pressure of steel wire rope, is set so as to efficiently solve large-area power-cuts Standby self-healing problem.

3rd, simple structure, easy for installation, engaged position is small, can be arranged on by elevator(lift) machine room or traction machine, is easy to old ladder to change Make, solving existing elevator does not have the problem of deadman's brake installation site.

Certain above-described embodiment is familiar with this only to illustrate technology design of the present utility model and feature its object is to allow The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this Enclose.Equivalent transformation or modification that all Spirit Essences according to the utility model main technical schemes are done, should all cover in this reality Within new protection domain.
