Fall safety guard.
Background technique
Existing elevator, elevator and stakcer crane are equipped with chain rupture tenesmus protection and capture brake apparatus, due to the protection
Device is made of link mechanism, and therefore, existing structure is complicated, and failure is more, takes up space greatly and the problem of Maintenance Difficulty.
Summary of the invention
The purpose of this utility model is that structure is complicated, failure existing for the existing chain rupture tenesmus protection capture brake apparatus of solution
It is more, take up space big and Maintenance Difficulty the technical issues of, a kind of magnetic force is provided and controls anti-fall catcher.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
The anti-fall catcher of a kind of magnetic force control, by matrix, two blocks of permanent magnets, two positioning pins, braking abaculus, electromagnetism
Iron and cover board composition, described matrix are equipped in the wedge shape that can accommodate braking guide rail, permanent magnet, braking abaculus and electromagnet
Chamber, first block of permanent magnet are located at the side on matrix wedge shape inner cavity top, and fixed be located at of second block of permanent magnet brakes abaculus
Bottom and no magnetic strength material that is surrounded by second block of permanent magnet, described two positioning pins are located at the one side of braking abaculus
It above and is separated by a certain distance, the braking abaculus is located at the middle part of the wedge-shaped inner cavity of matrix and can move, the electromagnet setting
In the side of matrix wedge shape inner cavity lower part, the middle and upper part on described cover board one side is equipped with guide groove, wedge of the cover plate lid in matrix
On shape inner cavity and it is located at two positioning pins being arranged on braking abaculus in the guide groove of cover board.
The beneficial effects of the utility model are：
Since the utility model uses above-mentioned technical proposal, keep its structure simple, it is small in size, it takes up space small, reacts
Sensitive, securely and reliably, maintenance is easy, while can realize generalization, standardization, provides elevator, the single double columns of different model
Formula piler uses, and can also provide the transformation of old equipment, economic technology is good.Therefore, compared with the background art, this reality
With it is novel have structure it is simple, it is small in size, take up space it is small, be quick on the draw, safe and reliable and simple and convenient for maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the left view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in FIG. 1 to 3, one of the present embodiment magnetic force controls anti-fall catcher, it is permanent by 7, two pieces of matrix
2,6, two positioning pins of magnet 3,5, braking abaculus 4, electromagnet 8 and cover board 9 form, and described matrix 7, which is equipped with, can accommodate braking
Guide rail 1, permanent magnet, the wedge-shaped inner cavity for braking abaculus 4 and electromagnet 8, first block of permanent magnet 2 are located at the wedge-shaped inner cavity of matrix 7
The side on top, the fixed bottom for being located at braking abaculus 4 of second block of permanent magnet 6 are simultaneously set in the surrounding of second block of permanent magnet 6
Whether there is or not magnetic strength material, described two positioning pins 3,5 are located on the one side of braking abaculus 4 and are separated by a certain distance, the braking
Abaculus 4 is located at the middle part of the wedge-shaped inner cavity of matrix 7 and can move, and the one of the wedge-shaped inner cavity of matrix 7 lower part is arranged in the electromagnet 8
Side, the middle and upper part on described 9 one side of cover board are equipped with guide groove 10, and the cover board 9 covers on the wedge-shaped inner cavity of matrix 7 and setting is made to exist
Two positioning pins 3,5 on braking abaculus 4 are located in the guide groove 10 of cover board 9.The wedge-shaped inner cavity brake empty of 9 closed base of cover board 7
Between, two positioning pins 3,5 keep the guiding of the braking up and down motion of abaculus 4 in guide groove 10.
One of the present embodiment magnetic force controls anti-fall catcher and is fixed on lifting device by matrix 7 and leads braking
The other side that rail 1 is stuck in the wedge-shaped inner cavity of matrix 7 keeps braking guide rail 1 adjacent with abaculus 4 is braked.
The working principle of the utility model is：
When exceed the speed limit chain rupture when, protective switch give electromagnet 8 be powered on, brake 4 lower part of abaculus permanent magnet 6 and electromagnet 8
Polarity is identical, repels braking abaculus 4 is pushed to move upwards the gravisphere into permanent magnet 2 upwards, permanent magnet 2 is attracting will
Braking abaculus 4 moves upwards the braking surface for making to brake abaculus 4 into the inclined-plane vacancy in the wedge-shaped inner cavity of matrix 7 and compresses braking
Guide rail 1 realizes insertion braking.
When working, permanent magnet 6 and electromagnet 8 are attracting, and braking abaculus 4 is made to stablize the electromagnet 8 behind bottom, work
Power-off, braking abaculus 4 reset under gravity and 6 graviational interaction of permanent magnet.
