Specific embodiment
In the following, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
As shown in Figs 1-4, a kind of anti-squat system of general's pillar ocean platform crane, mounted on general's pillar ocean
On platform crane, as known technology, general's pillar ocean platform crane includes turntable 9, kingpost 8, door frame 2
(the pulley pack support of truss and superposed support pulley blocks 20 including lower part), uses bearing between turntable 9 and kingpost 8
Connection, convenient for rotating, door frame 2 is connected by axis pin 22 with turntable 9, and 2 top of door frame is connected by bearing with kingpost 8, door frame 2
It can be around 360 degree of revolutions of axis of kingpost 8 with turntable 9；Turntable 9 passes through axis pin 23 and the bottom phase for being bolted arm arm support 1
Rotation connection, axis pin 23 play connection and rotary action；Arm arm support 1 has main chord 5, and the upper end of door frame 2 passes through pulley pack support
It is equipped between the pulley blocks (not shown) of 1 front end of pulley blocks 20 and arm arm support and is connected by steel wire rope (not shown), door frame 2
Structure it is similar to the structure of arm arm support 1, formed by steel-pipe welding.
Described in background technology, hypsokinesis can be occurred in amplitude changing process by arm arm support 1, in the present invention,
General's pillar ocean platform crane is equipped with anti-squat system, and the anti-squat system includes anti-hypsokinesis stent 3, the anti-hypsokinesis
Stent is 2, and relative symmetry arrangement is mounted on can be on the intermediate 7 that kingpost 8 rotates (shown in Figure 3), the centre
Body 7 is welded between the truss of the door frame 2 and the pulley pack support of support pulley blocks 20, and in the front end of anti-hypsokinesis stent 3
(one end for being directed toward the main chord 5 of arm arm support 1) has bump rubber 4, as shown in figure 4, the anti-hypsokinesis stent 3 uses bolt
On intermediate 7, the bump rubber 4 is mounted on the front end of anti-hypsokinesis stent by bolt 6, nut 62, gasket 61,
It is shown in Figure 7；The front end face of the bump rubber 4 of the anti-hypsokinesis stent and the angle a of horizontal plane are (see Fig. 5 into 82 degree
It is shown), anti-hypsokinesis stent can so be caused to be preferably bonded corresponding two main chords 5 of the arm arm support 1, so as to
It realizes when hypsokinesis is to corresponding position during arm luffing range of cantilever support, the groove can be bonded with the main chord and contact with reality
Now prevent that arm arm support hypsokinesis is excessive,
It is shown in Figure 6, specifically, the intermediate 7 is equipped with bolt hole 10, for two anti-hypsokinesis stents 3
The installation of connection bolt, and the intermediate 7 for passing through screw bolt and nut and door frame is connected to a fixed, wherein, the intermediate 7 with will
Army's column 8 is connected by bearing, facilitates rotation, and door frame 2 is made to be rotated compared with the kingpost 8.
Shown in Figure 6, the intermediate 7 includes upper plate 71 and lower plate 72 and is connected upper plate and the middle part of lower plate
73, the both sides of the middle part are equipped with the bolt hole 10, and the inside of the middle part passes through bearing arrangement and the kingpost
Rotate connection, and realizes that the door frame 2 rotates with the kingpost 8 and be connected.
The lower plate 72 is connected with the lower weld of door frame 2, the pulley blocks that the upper end of the upper plate and the door frame is equipped with
20 pulley bracket is connected, as shown in Figure 1.
When ocean platform crane arm luffing range of cantilever support is to maximum angle, as shown in Figure 1, on the one hand anti-hypsokinesis stent profit
With the supporting role of kingpost, it can prevent arm arm support from continuing hypsokinesis and tumbling, another aspect bump rubber 4 can be with
Slow down the rigid shock between arm arm support and kingpost 8, when unsafe condition, cushioning effect can be functioned well as, reduce
The structures such as kingpost, the door frame of ocean platform crane bear inertia impact.
From said structure, the present invention can not only prevent ocean platform crane from tumbling backward in amplitude changing process, solution
The rigid shock problem that may certainly occur between arm arm support and kingpost, moreover it is possible to be generated centainly to the luffing of arm arm support
Position-limiting action solves ocean platform crane security hidden trouble present in course of normal operation
In the present invention, the agent structure of the anti-hypsokinesis stent is welded by rectangular tube, I-steel and steel plate, material
It is Q345B；The steel plate of welding is beaten there are four bolt mounting holes, specifically, as shown in Figure 4, including by rectangular tubular into branch
Frame body 30 and be located at rack body 30 front end for connecting the front end connecting plate 34 of bump rubber 4, using steel plate
Make, be located at the rack body 30 rear end for the connecting portion formed by i shaped steel that is connected with the intermediate 7
31, which is connected with the 10 L-shaped structure of rack body, and the connecting portion 31 is used to be connected with intermediate 7
The face connect is equipped with intermediate connecting plate 32, is made of steel plate, and intermediate connecting plate 32 is equipped with the bolt on corresponding intermediate 7
The corresponding bolt hole 33 in hole 10.
Shown in Figure 8 in the present invention, the bump rubber 4 is designed using band groove, and middle part has groove 41,
Corner is cut thin, and is being cut thin corner equipped with bolt hole 42, installation bolt is facilitated to pass through bolt with front end connecting plate 34
Connection；The connection of anti-each component of hypsokinesis stent is connected by screw bolts.
The present invention can not only be effectively prevented ocean platform crane and tumble backward in amplitude changing process, solve arm arm
Rigid shock problem between frame and kingpost, moreover it is possible to certain position-limiting action be generated to the luffing of arm arm support, along with ocean
The rope control and the effect of range limiter of platform crane itself so that the ocean platform crane arm arm support elevation angle more holds
It is easy to control, it is safer.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
