Description
Technical field
The present invention relates to a kind of anti-falling mechanism of elevator.
Background technology
When elevator works, weight slides from the bottom up in the effect lower edge lifting track front end face such as chain sprocket, real
Now transport.But sometimes because chain sprocket occurs to loosen or is influenceed by other factors etc., weight can occur suddenly during transport
Fall, if being now easily caused weight without the protection of corresponding falling-proof safety device on elevator and directly pounding in following people
Or on thing, trigger security incident.
The content of the invention
The purpose of the present invention：The defects of in order to overcome prior art, the invention provides a kind of fall arrest machine of elevator
Structure, it can prevent weight from falling in chain breakage, and use is safer, simple in construction, and stability is good.
Technical scheme：A kind of anti-falling mechanism of elevator, it is characterised in that：Include upgrade block, lifting
Guide rail, limiting plate, connecting rod, described upgrade block are vertically slidably matched with lift rail, and limiting plate is cut with scissors with lift rail
Connect, limiting plate one end is positive stop end, and the other end is drive end, and described upgrade block is provided with connecting rod, in described connecting rod
Hold as chain connection end, the drive end with limiting plate, the lower end of connecting rod are hinged respectively at the both ends of connecting rod, the drive end of limiting plate
Extended to through upgrade block outside upgrade block, the reset for resetting limiting plate is additionally provided between described lift rail and limiting plate
Part, several are vertically provided with described lift rail and is used for when return unit is by spacing sheet reset for the limit of limiting plate
The stopper slot that position end is caught in.
Using above-mentioned technical proposal, when chain normal work is lifted, chain pulls upgrade block to rise through connecting rod, so as to
The drive end of limiting plate is driven to be rotated up；In chain breakage, in the presence of return unit, spacing sheet reset rotates, spacing
The positive stop end of plate can be caught in when upgrade block falls in lift rail wherein in a stopper slot, so as to prevent upgrade block from continuing
Play a part of fall arrest in whereabouts.Therefore, the anti-falling mechanism of the elevator of this structure, it can be prevented in chain breakage
Weight falls, and use is safer, simple in construction, and stability is good.
The further setting of the present invention：Described return unit uses back-moving spring, the both ends of back-moving spring respectively with lifting
The drive end connection of guide rail, limiting plate.
Further set using above-mentioned, this return unit set-up mode, its is simple in construction, and reseting performance is stable, reliable.
The further setting of the present invention：The seat that described upgrade block includes two side and is arranged between two side
Body, connecting rod are arranged on pedestal, and described lift rail includes two guide rails, and two guide rails are respectively positioned at upgrade block two side
Outside, described connecting rod, connecting rod, limiting plate, return unit are respectively equipped with two and along upgrade block settings substantially symmetrical about its central axis.
Further set using above-mentioned, this upgrade block, lift rail and connecting rod, connecting rod, limiting plate, return unit
Set-up mode so that upgrade block stationarity is good, will not produce inclination, more stable.
The present invention's is further set again：The lateral wall of described upgrade block is provided with roller, roller and lift rail
Madial wall contradict.
Using above-mentioned setting further again, being slidably matched for upgrade block and lift rail is realized by roller, it rubs
Power is small, sliding stability, reliable.
Brief description of the drawings
Structural representation when Fig. 1 is specific embodiment of the invention chain normal work；
Structural representation when Fig. 2 is specific embodiment of the invention chain breakage.
Embodiment
