Abstract
The invention discloses a self-locking type pull rod used for lifting a gate. The self-locking type pull rod comprises a rod body, and an upper lifting lug and a lower lifting lug which are fixedly connected to the upper end and the lower end of the rod body, wherein the upper lifting lug and the lower lifting lug are both of a double-lifting-lug structure; a lifting hole of the upper lifting lug is of a long hole structure formed along the longitudinal direction of the rob body; a locking shoulder is arranged on the rod body positioned below the upper lifting lug; the locking shoulder is formed by an upper support platform and a lower support platform which are fixed on the rod body at an interval up and down; and the upper support platform and the lower support platform are respectively arranged by extending to two sides of the rod body along the axial direction of the lifting hole of the upper lifting lug. The self-locking type pull rod has the advantage of being capable of keeping a vertical state all the time without assistance of external force by utilizing the plugging locking function of the pull rod, thus being convenient for pin-penetrating connection of the pull rod and being especially applicable to occasions of lifting of gates by match of the pull rod with a large-tonnage mobile gate hoist.
Description
Technical field
The present invention relates to the gate used in hydraulic engineering, be especially for lifting by crane the self-locking pull bar of gate.
Background technology
Using pull bar to coordinate rolling open and close machine lifting gate to be method conventional in hydraulic engineering, pull bar opens and closes as elevator
Effectively supplementing of machine lift, greatly reduces the impulse stroke of rolling open and close machine, reduces size and the weight of rolling open and close machine, joint
Save equipment investment.At present, when coordinating rolling open and close machine lifting gate with pull bar, pull rod device hangs Tou Hezha at rolling open and close machine
Between gantry crane ear, each parts use bearing pin to connect, and pull bar chain one end of more piece pull bar composition is hung head with rolling open and close machine and is connected, and one
End is connected on gate lifting eye, and the connection of pull bar, dismounting are all completed by manual operation on inspection platform.Above-mentioned use pull bar is joined
Closing rolling open and close machine lifting gate and be only applicable to gate vertical lift operating mode, under such conditions, rolling open and close machine hangs head, gate
Hanger and pull bar chain are the most perpendicular to the ground, and pull bar is long thin rod shape, hang mounting or dismounting between head and gate lifting eye at rolling open and close machine and draw
During bar, only pull bar vertically placed the docking being just easy to hanger hole each other and wear axle.Drawing of Large Copacity rolling open and close machine
Bar is heavier, when cylinder lever connecting rod, generally uses interim lifting appliance that pull bar vertically hangs in inspection platform, for ensureing pull bar
Vertically state, the suspender of interim lifting appliance can not depart from pull bar all the time, hangs head with rolling open and close machine at pull bar and wears axle and be connected
Time, rolling open and close machine hangs the suspender of head and interim lifting appliance and will interfere, cause rolling open and close machine hang head cannot with draw
Bar connects smoothly.If during it addition, interim lifting appliance is in same work surface with rolling open and close machine, the two can not carry out work simultaneously
Make, if carried out the work simultaneously, also can interfere with each other.Only when inspection platform called in by pull bar by interim lifting appliance and moves
After walking, rolling open and close machine just has the space of operation.For ensureing that pull bar can be worn axle smoothly and connect, when interim lifting appliance is removed
After, how to keep the vertical state of pull bar, be the problem needing to solve.
Summary of the invention
Present invention aim at providing a kind of self-locking pull bar for lifting by crane gate.
For achieving the above object, the present invention takes following technical proposals:
Self-locking pull bar for lifting by crane gate of the present invention, including the body of rod, is connected in the upper hanger of described body of rod upper and lower end
With lower hanger, described upper and lower hanger is double shackle structure；The lifting hole(eyelet) of described upper hanger is the elongated hole knot longitudinally offered along the body of rod
Structure, be positioned on the body of rod below hanger be provided with locking shoulder, described locking shoulder by upper and lower interval be fixed on the body of rod upper
Support platform and lower support platform are constituted, and described upper and lower support platform axially extends to body of rod both sides along the lifting hole(eyelet) of upper hanger respectively
Arrange.
The transverse section of the described body of rod is i-beam structure, and the bottom of the body of rod is box-structure.
The invention has the advantages that described pull bar utilizes the locking latch function of self, being not required to can be all the time by external strength
Keeping vertical state, the pin of wearing facilitating pull bar connects, and is particularly suited for pull bar and coordinates large-tonnage travelling hoist to play port-cullis
The occasion of door.

Detailed description of the invention
As Figure 1-4, the self-locking pull bar for lifting by crane gate of the present invention, including the body of rod 1, the described body of rod 1
Transverse section is i-beam structure (as shown in Figure 3), and the bottom of the body of rod 1 is box-structure (as shown in Figure 4)；Upper and lower at the body of rod 1
End has been respectively fixedly connected with hanger 2 and lower hanger 3, and described upper and lower hanger 2,3 is double shackle structure；For making pull bar after sleeve
The axle of wearing that can carry out hanger connects, and the lifting hole(eyelet) 4 of upper hanger 2 is the long pore structure longitudinally offered along the body of rod 1, is positioned at hanger 2
Be provided with locking shoulder on the body of rod 1 of lower section, upper support platform 5 that described locking shoulder is fixed on the body of rod 1 by upper and lower interval and under
Support platform 6 is constituted, and along the lifting hole(eyelet) 4 of upper hanger 2, axially to the body of rod 1 both sides, extension sets described upper and lower support platform 5,6 respectively
Put.Upper support platform 5, for supporting another joint pull bar being connected with upper hanger 2, keeps pull bar to be in vertical state；Lower support
Platform 6 locks with gate for the pull bar chain of pull bar or more piece pull bar composition on inspection platform.When the present invention uses, Ren Heyi
The upper hanger 2 of joint pull bar all can vertically sleeve under another pull bar being attached thereto in hanger 3.
When headstock gear uses the present invention to lift by crane gate, pull bar attended operation order following (as a example by gate declines):
The first step: vertically sling by pull bar 7 waiting with interim lifting appliance, draws lower hanger 3 sleeve of pull bar 7 waiting connecing
On the upper hanger 2 of bar 8 (as shown in Figure 5), remove interim lifting appliance, and keep pull bar 7 waiting to carry out vertically upward wearing axle even
Connect operation；
A second step: headstock gear hangs 9 and falls, and is connected (as shown in Figure 6) with wearing pin after hanger 2 para-position on pull bar 7 waiting, treats this moment
Connect pull bar 7 to have connected.
3rd step: headstock gear 10 does enhancing action and releases the locking of gate 11, then by pull bar 7 waiting, connect pull bar 8
And gate 11 is together sling and transfers along gate slot, after transferring certain distance, pull bar 7 waiting is locked the lower support platform 6 of shoulder with
Locking beam 12 is locked on inspection platform 13 jointly, disconnects headstock gear and hangs the connection between 9 and pull bar chain, under carrying out the most again
The access of one joint pull bar, the connection of next joint pull bar repeats the first two steps (as shown in Figure 7).
