Description

A kind of stepless locking device
Technical field
The present invention relates to a kind of mechanical lockings, and in particular to a kind of stepless locking device is suitable for hydraulic headstock gear The gate of operation in the mechanical caging of any open position, be particularly suitable for hydraulic headstock gear operation lower shaft driving steel-slag sand, Flap gate, the gate of other such as worm-type open-close machines operation is see also using.
Background technique
There are several types of the locking (letters of: beam type for the mechanical locking of the gates using hydraulic headstock gear operation all at present Strutbeam, cantilever beam), water chestnut locking, pin shaft locking (containing Electrohydraulic push rod lock).Due to the limitation of space, structure etc., existing machinery The installation site quantity of locking is limited: the mechanical caging position usually not more than 3 of lower shaft driving steel-slag sand, and plane Vertical lifting door, gates of segmental shape mechanical caging position be usually all 1 (fully open position of corresponding gate or maintenance position).It cannot Realize the mechanical caging at any opening degree
For the gate for adjusting requirement with flow of hydraulic headstock gear operation, it is desirable that gate is able to maintain any At aperture, existing keeping method is to utilize the realization of hydraulic headstock gear shut-off valve hydraulic self-locking, so that gate is maintained at any Aperture.Its defect is that hydraulic headstock gear has been in pressure condition for a long time, can shorten oil cylinder in this case between shut-off valve The service life of all sealing elements.
Summary of the invention
For the mechanical caging requirement that overcomes the mechanical locking of the prior art not to be able to satisfy at gate any opening degree Defect, the present invention provide a kind of stepless locking device, to solve machinery of the gate of hydraulic headstock gear operation at any opening degree Lockout issue.After mechanical caging, hydraulic headstock gear is in pressure release (no pressure) state, and avoiding to be in for a long time has pressure condition to cause Hydraulic seal, which damages due to crushing to shorten the working life, influences hydraulic headstock gear normal operation.
The technical solution adopted by the present invention to solve the technical problems is: a kind of stepless locking device, including upper lock arm Girder steel and lower lock arm girder steel.The upper surface of the lower lock arm girder steel is equipped with ratchet, lower lock arm girder steel and hydraulic headstock gear Hydraulic cylinder assembling it is integral or weld together.One end of the upper lock arm girder steel is equipped with upper lock arm suspending head, locking Fixed arm suspending head and upper lock arm girder steel are affixed, upper lock arm suspending head pass through together with hydraulic headstock gear suspending head axis and gate lifting eye or The connecting lever lifting lug of person's lower shaft driving steel-slag sand is linked;The other end of upper lock arm girder steel is equipped with electromagnetic release device and ratchet Plate, claw plate and upper lock arm girder steel are affixed, and electromagnetic release device passes through electromagnetic force for upper lock arm girder steel in the energized state It jacks up and is rotated around upper lock arm suspending head end, so that the ratchet of the ratchet of claw plate and lower lock arm girder steel is detached from, gate is solved Lock, while hydraulic headstock gear operates gate opening/closing;Then upper lock arm girder steel falling makes spine to electromagnetic release device under power failure state The ratchet of tooth plate and the ratchet of lower lock arm girder steel are mutually twisted, and gate is i.e. locked, and hydraulic headstock gear shuts down pressure release at this time.
Beneficial effects of the present invention: when gate needs to have the function of maintaining any opening degree position, existing locking dress The mechanical caging requirement for not being able to satisfy gate any opening degree position is set, therefore hydraulic headstock gear must maintain pressure condition the moment and incite somebody to action Gate is handled a certain open position (i.e. hydraulic self-locking).This locking device solves the problems, such as this, may be implemented to appoint in gate Mechanical caging function at meaning open position avoids hydraulic headstock gear in running order for a long time, to extend headstock gear Service life, reduce the repair and maintenance number of headstock gear, save repair and maintenance cost.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of stepless locking device of the present invention, including upper lock arm girder steel 1 and lower lock arm girder steel 2, the upper surface of lower lock arm girder steel 2 is equipped with ratchet, and the hydraulic cylinder assembling of lower lock arm girder steel 2 and hydraulic headstock gear 3 is integral Or weld together.One end of upper lock arm girder steel 1 is equipped with upper lock arm suspending head 12, upper lock arm suspending head 12 and upper lock arm Girder steel 1 welds, and connecting lever 5 of the upper lock arm suspending head 12 together with the suspending head of hydraulic headstock gear 3 with lower shaft driving steel-slag sand passes through axis It interconnects.The other end of upper lock arm girder steel 1 is equipped with electromagnetic release device 11 and claw plate 13, claw plate 13 and upper lock arm Girder steel 1 welds;Ratchet snap-lock of the ratchet of claw plate 13 usually with lower lock arm girder steel 2 lives gate.
After electromagnetic release device 11 must be electric, upper lock arm girder steel 1 is under electromagnetic force around lower shaft driving steel-slag sand The lifting lug center rotating of connecting lever 5, rotation angle can be arranged by current strength, so that the ratchet of claw plate 13 and lower lock arm The ratchet disengaging of girder steel 2, realizes gate unlock, and then the work of hydraulic headstock gear 3 pushes away the connecting lever 5 of (drawing) lower shaft driving steel-slag sand in fact The gate flap 4 of existing lower shaft driving steel-slag sand opens and closes operation, when 4 aperture of gate flap of lower shaft driving steel-slag sand reaches desired position, 11 power loss of electromagnetic release device, upper lock arm girder steel 1 fall, and the ratchet of claw plate 13 is engaged with the ratchet of lower lock arm girder steel 2, The gate flap 4 of lower shaft driving steel-slag sand is locked to the open position, then 3 termination of pumping pressure release of hydraulic headstock gear.
Lock arm girder steel 1 and lower lock arm girder steel 2 are mutually twisted by ratchet in the present invention realizes each open position of gate Mechanical caging, that is, stepless locking.
Invention has been described for above-described embodiment combination attached drawing, and but it cannot be understood as to the invention patent The limitation of range, it is noted that for those of ordinary skill in the art, in the premise for not departing from present inventive concept Under, with equivalent replacement or equivalent transformation mode technical solution obtained, these are all belonged to the scope of protection of the present invention.
