Abstract
But spacing hoist headstock gear of auto -lock, including hoist headstock gear and gate, the hoist headstock gear passes through the cable wire and links to each other with the gate, the gate sets up in the gate slot, the hoist headstock gear includes the cover, the cover embeds auto -lock stop gear, auto -lock stop gear includes spacing axle, spacing plectrum, spacing post, a spring, the sealing washer clamp plate, spacing rocking arm, the rocking arm clamp plate, shift fork and declutch shift shaft, spacing rocking arm couples through the bolt with spacing axle, and fix in the cover through sealing washer clamp plate and rocking arm clamp plate, thereby it drives spacing axle rotation to rotate spacing rocking arm, when spacing axle rotates an allocation, the shift fork that drives the spacing plectrum of spacing plectrum messenger moves on the declutch shift shaft, it is continuous with the spacing axle on the spacing plectrum that spacing post passes through the spring. The utility model discloses a set up auto -lock stop gear in the hoist headstock gear, realized the gate -lowering mechanism tool formula auto -lock limit function of hoist headstock gear, have rational in infrastructure, convenient to use and the spacing reliable and stable advantage of auto -lock.
Description
Technical field
The utility model relates to a kind of gate of Hydraulic and Hydro-Power Engineering, be specifically related to a kind of can the rolling open and close machine of self-locking limit.
Background technology
In some large hydraulic engineerings, often relate to open-close sluice gate, wherein wider with vertical winding type open-close sluice gate application, vertical winding type open-close sluice gate has that structure is simple, the advantage of low cost of manufacture and long service life, but vertical winding type open-close sluice gate can only realize opening and closing two states at present, cannot regulate discharge, limit the promotion and application of winding type open-close sluice gate to a great extent.
Utility model content
The utility model provide a kind of can the rolling open and close machine of self-locking limit, to solve the problem that cannot regulate discharge that prior art exists.
The utility model comprises rolling open and close machine and gate, rolling open and close machine is connected with gate by cable wire, gate locating is in gate slot, solving the technical scheme that its technical problem adopts is that rolling open and close machine comprises cover, the built-in self-locking limit mechanism of cover, self-locking limit mechanism comprises limit shaft, spacing plectrum, limited post, spring, sealing ring pressing plate, spacing rocking arm, rocking arm pressing plate, shift fork and declutch shift shaft, spacing rocking arm and limit shaft pass through Bolt Connection, and be fixed in cover by sealing ring pressing plate and rocking arm pressing plate, rotary spacing rocking arm thus drive limit shaft rotate, when limit shaft turns to certain position, drive spacing plectrum that the shift fork of spacing plectrum is moved on declutch shift shaft, limited post is connected with the limit shaft on spacing plectrum by spring.
Above-mentioned gate slot inside top arranges guide pads, prevents cable wire and gate slot friction from causing gate slot to damage.
When the utility model uses, when rolling open and close machine drives gate to move to assigned address, rotary spacing rocking arm thus drive limit shaft rotate, when limit shaft turns to certain position, drive spacing plectrum, the shift fork of the prong toggle mechanism of spacing plectrum is moved on declutch shift shaft, limited post is by the effect of spring simultaneously, spacing plectrum realizes self-locking limit effect, thus gate is moved carry out self-locking limit, in process, spacing rocking arm and limit shaft pass through Bolt Connection, and O type circle is fixed in cover by sealing ring pressing plate, play the effect preventing self-locking limit leakage of oil.
The utility model, by arranging self-locking limit mechanism in rolling open and close machine, achieves the gate-lowering mechanism tool formula self-locking limit function of rolling open and close machine, has rational in infrastructure, easy to use and that self-locking limit is reliable and stable advantage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model rolling open and close machine.
1 rolling open and close machine, 2 cable wires, 3 gates, 4 gate slotes, 5 guide pads, 11 covers, 12 limit shafts, 13 spacing plectrums, 14 limited posts, 15 springs, 16 sealing ring pressing plates, 17 spacing rocking arms, 18 rocking arm pressing plates, 19 shift forks, 20 declutch shift shafts in figure.
Detailed description of the invention
As depicted in figs. 1 and 2: a kind of can the rolling open and close machine of self-locking limit, rolling open and close machine 1 is connected with gate 3 by cable wire 2, gate 3 is arranged in gate slot 4, gate slot 4 inside top arranges guide pads 5, preventing cable wire 2 and gate slot 4 from rubbing causes gate slot to damage, rolling open and close machine 1 comprises cover 11, the built-in self-locking limit mechanism of cover 11, self-locking limit mechanism comprises limit shaft 12, spacing plectrum 13, limited post 14, spring 15, sealing ring pressing plate 16, spacing rocking arm 17, rocking arm pressing plate 18, shift fork 19 and declutch shift shaft 20, spacing rocking arm 17 passes through Bolt Connection with limit shaft 12, and be fixed in cover 11 by sealing ring pressing plate 16 and rocking arm pressing plate 18, rotary spacing rocking arm 17 thus drive limit shaft 12 rotate, when limit shaft 12 turns to certain position, drive spacing plectrum 13 that the shift fork 19 of spacing plectrum 13 is moved on declutch shift shaft 20, limited post 14 is connected with the limit shaft 12 on spacing plectrum 13 by spring 15.
When the utility model uses, when rolling open and close machine drives gate to move to assigned address, rotary spacing rocking arm thus drive limit shaft rotate, when limit shaft turns to certain position, drive spacing plectrum, the shift fork of the prong toggle mechanism of spacing plectrum is moved on declutch shift shaft, limited post is by the effect of spring simultaneously, spacing plectrum realizes self-locking limit effect, thus gate is moved carry out self-locking limit, in process, spacing rocking arm and limit shaft pass through Bolt Connection, and O type circle is fixed in cover by sealing ring pressing plate, play the effect preventing self-locking limit leakage of oil.
Claims (2)
1. one kind can the rolling open and close machine of self-locking limit, comprise rolling open and close machine and gate, rolling open and close machine is connected with gate by cable wire, gate locating is in gate slot, it is characterized in that rolling open and close machine comprises cover, the built-in self-locking limit mechanism of cover, self-locking limit mechanism comprises limit shaft, spacing plectrum, limited post, spring, sealing ring pressing plate, spacing rocking arm, rocking arm pressing plate, shift fork and declutch shift shaft, spacing rocking arm and limit shaft pass through Bolt Connection, and be fixed in cover by sealing ring pressing plate and rocking arm pressing plate, rotary spacing rocking arm thus drive limit shaft rotate, when limit shaft turns to certain position, drive spacing plectrum that the shift fork of spacing plectrum is moved on declutch shift shaft, limited post is connected with the limit shaft on spacing plectrum by spring.
