Abstract
The utility model is related to a kind of safety tongs of towed elevator; a kind of safety guard of vertical lift elevator; hoistway including counterweight and the receiving counterweight; safe wrench structure is provided with the hoistway inwall, the safe wrench structure includes being embedded in the electromagnetic structure of the hoistway and the electromagnetic structure coordinates and the iron block of an angle can be rotated in the hoistway.Using such scheme for the safety tongs braked to counterweight.
Description
Technical field
The utility model belongs to a kind of safety guard of vertical lift elevator, particularly a kind of safety of towed elevator
Pincers.
Background technology
A kind of vertical lift elevator is disclosed in the Publication No. CN205472090U of currently available technology open file
Multi-purpose bidirectional Electromgnetic seat is clamped, it is characterized in that, Electromgnetic seat pincers are that the electromagnetic force produced using electromagnet is dynamic as action
Power, using bi-directional braking structure, the braking action by braking member to guide rail or hoist ropes is realized to the two-way deceleration of car
The defencive function of stop.
This structure acted on hoist ropes, can cause the service life of hoist ropes to cut short, and can cause because of hoist ropes
Security incident caused by insecure.
Utility model content
The purpose of this utility model is the safety tongs in order to be braked to counterweight.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of peace of towed elevator
Full pincers, including counterweight and the hoistway for accommodating the counterweight, it is characterised in that be provided with safe wrench structure on the hoistway inwall,
The safe wrench structure includes being embedded in the electromagnetic structure of the hoistway and the electromagnetic structure and coordinated and can be in the hoistway
Rotate the iron block of an angle.
Preferably, the iron block is rotated in the direction of motion of the counterweight.The direction of motion of iron block can be level
Direction, is provided with the spring of a receipts compression stress, when electromagnetic force disappears, spring is by iron between iron block and electromagnetic structure
Block is ejected, but hoistway is excessive in order to prevent iron block from stretching into, and spring can also provide a pulling force so that iron block enters the body of hoistway
Product is smaller.
Preferably, the angle ranging from the angle between one 0-30 °.The rotation direction of generally preferably iron block is vertical side
To, angle that this angle when being iron block free movement produce consistent with the direction of motion of counterweight.
Preferably, the center of gravity deviation free end of the iron block, described in when the iron block is not acted on by the electromagnetic structure
Iron block can rotate an angle and exposed to counterweight described in the hoistway inner barrier.
Preferably, evenly distributed in the hoistway have the electromagnetic structure at least wanting to wait with number of floor levels.One iron block is perhaps
The impact of the free-falling bad student of counterweight can not be stopped, but the effect of stop can be played, can be delayed when after the effect of multiple iron blocks
The speed of the decline of counterweight is solved, then can be by the wide complete stop of one of iron.
In summary, the utility model realizes by stopping counterweight to realize that counterweight will not be directly from by falling
Body is in shaft bottom.It is easy to operate and total is simple.
Brief description of the drawings
Fig. 1 is schematic side view of the present utility model；
In Fig. 1,1- counterweights, 2- hoistways, the safe wrench structures of 3-, 31- electromagnetic structures, 32- iron blocks.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1.
Peace is provided with a kind of safety tongs of towed elevator, including counterweight 1 and the hoistway 2 for accommodating counterweight 1, the inwall of hoistway 2
Full wrench structure 3, the electromagnetic structure 31 that safe wrench structure 3 includes being embedded in hoistway 2 coordinates with electromagnetic structure 31 and can be in hoistway 2
Rotate the iron block 32 of an angle.
Iron block 32 is rotated in the direction of motion of counterweight 1.And the angle rotated is 30 °.The center of gravity deviation of iron block 32 is freely
End, iron block 32 can rotate 30 ° and exposed to the inner barrier counterweight 1 of hoistway 2 when iron block 32 is not acted on by electromagnetic structure 31.
Offered in hoistway 2 below a cuboid, the diagonal plane of the cuboid is more than electromagnetic structure 31, diagonal plane to be
Rotating shaft on iron block 32, iron block 32 is in the bottom of diagonal plane, the top of the center of gravity deviation cuboid of the iron block 32 and deviation length
On the outside of cube, the free-falling of iron block 32 can be realized.
It is evenly distributed in hoistway 2 to have the electromagnetic structure 31 that grade is thought with number of floor levels.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
