Abstract
The utility model discloses a kind of self-locking pull bar for lifting by crane gate, including the body of rod, be connected in the upper hanger of described body of rod upper and lower end and lower hanger, described upper and lower hanger is double shackle structure；The lifting hole(eyelet) of described upper hanger is the long pore structure longitudinally offered along the body of rod, it is positioned on the body of rod below hanger and is provided with locking shoulder, upper support platform and lower support platform that described locking shoulder is fixed on the body of rod by upper and lower interval are constituted, and described upper and lower support platform is axially extended to body of rod both sides along the lifting hole(eyelet) of upper hanger respectively.This utility model advantage is that described pull bar utilizes the locking latch function of self, is not required to remain vertical state by external strength, and the pin of wearing facilitating pull bar connects, and is particularly suited for pull bar and coordinates the occasion of large-tonnage travelling hoist lifting gate.
Description
Technical field
This utility model relates to the gate used in hydraulic engineering, and the self-locking being especially for lifting by crane gate draws
Bar.
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
This utility model purpose is to provide a kind of self-locking pull bar for lifting by crane gate.
For achieving the above object, this utility model takes following technical proposals:
Self-locking pull bar for lifting by crane gate described in the utility model, including the body of rod, is connected in described body of rod upper and lower end
Upper hanger and lower hanger, described upper and lower hanger is double shackle structure；The lifting hole(eyelet) of described upper hanger is for longitudinally offering along the body of rod
Long pore structure, be positioned on the body of rod below hanger be provided with locking shoulder, described locking shoulder be fixed on the body of rod by upper and lower interval
On upper support platform and lower support platform constitute, described upper and lower support platform respectively along the lifting hole(eyelet) of upper hanger axially to the body of rod
Both sides are extended.
The transverse section of the described body of rod is i-beam structure, and the bottom of the body of rod is box-structure.
This utility model advantage is that described pull bar utilizes the locking latch function of self, is not required to by external strength
Remaining vertical state, the pin of wearing facilitating pull bar connects, and is particularly suited for pull bar and coordinates large-tonnage travelling hoist to rise
The occasion of port-cullis door.

Detailed description of the invention
As Figure 1-4, the self-locking pull bar for lifting by crane gate described in the utility model, including the body of rod 1, the described body of rod
The transverse section of 1 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)；At the body of rod 1
Upper and lower 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 insert
The axle of wearing that can carry out hanger after set 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 and hangs oneself
Locking shoulder, the upper support platform 5 that described locking shoulder is fixed on the body of rod 1 it is provided with by upper and lower interval on the body of rod 1 below ear 2
Constituting with lower support platform 6, described upper and lower support platform 5,6 axially extends to the body of rod 1 both sides along the lifting hole(eyelet) 4 of upper hanger 2 respectively
Arrange.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 this utility model uses,
The upper hanger 2 of any joint pull bar all can vertically sleeve under another pull bar being attached thereto in hanger 3.
When headstock gear uses this utility model lifting 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, by lower hanger 3 sleeve of pull bar 7 waiting
Connect on the upper hanger 2 of pull bar 8 (as shown in Figure 5), remove interim lifting appliance, and keep pull bar 7 waiting to wear vertically upward
Axle attended 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, this
Carve pull bar 7 waiting 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).
