Abstract
The invention discloses an anti-wind device for a portal crane. The anti-wind device comprises a steel wire rope, and is characterized in that the steel wire rope passes through a through hole of an upper rope pressing block and a through hole of a lower rope pressing block, the upper rope pressing block and he lower rope pressing block are fixed on a bridge frame, the two ends of the steel wire rope are connected to form a closed ring, and the steel wire rope is straightened and is fixed on the two sides of the bridge frame. The anti-wind device provided by the invention has the advantages that the steel wire rope is fixed on the bridge frame along the moving direction, and the steel wire rope passes through the rope pressing blocks fixed on the bridge frame, therefore, when the bridge frame suffers from the big horizontal wind to have the tendency of being blown down, an angle is formed between the steel wire rope and the rope pressing block, so that the bridge frame can not be blown down.
Description
Technical field
The present invention relates to hoisting crane auxiliary device, particularly, relate to a kind of Anti-wind device for portal crane.
Background technology
At present, hoisting crane itself has certain anti-storm design for beam wind, but when exceeding calculating wind-force for some, is prone to accidents.Wheel when beam wind arrives certain wind-force in the cart walking mechanism of side will leave rail level, and cart easily arrives just.
Summary of the invention
In order to improve the safety of when beam wind is excessive hoisting crane walking, the invention provides a kind of can the wind-proof device of effective guarantee hoisting crane street safety.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of Anti-wind device for portal crane, comprise steel rope, it is characterized in that, described steel rope is along the through hole of crane span structure service direction through the upper cord-pressing block be fixed on crane span structure and the through hole of lower cord-pressing block, steel rope two ends connect the ring making steel wire cord type become closed, described steel rope is stretched direct join and is fixed on crane span structure both sides.
Further, described steel rope two ends are placed on pulley, and described pulley rotation is fixed on two pulley brackets before and after crane span structure service direction.
Further, before and after crane span structure service direction, near ground, pulley place, fixing cord-pressing block is fixedly housed between described pulley and crane span structure, on the downside of pulley, described steel wire penetrating fixes cord-pressing block through hole.
Further, the diameter of described upper cord-pressing block through hole, lower cord-pressing block through hole and fixing cord-pressing block through hole is all greater than steel rope 3cm-4cm.
The present invention by fixing steel rope on crane span structure service direction, and steel wire penetrating is fixed on the cord-pressing block on crane span structure, make when crane span structure be subject to laterally mistake strong wind time, when crane span structure will blow down, steel rope and cord-pressing block by generation angle, to ensure that crane span structure can not be blown down.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the lateral plan of Anti-wind device for portal crane of the present invention.
Reference numeral:
1-fixes cord-pressing block; 2-pulley; 3-steel rope; 4-crane span structure; Cord-pressing block under 5-; The upper cord-pressing block of 6-.
Detailed description of the invention
As shown in Figure 1, a kind of Anti-wind device for portal crane, comprise steel rope 3, steel rope 3 is along the through hole of crane span structure 4 service direction through the upper cord-pressing block 6 be fixed on crane span structure 4 and the through hole of lower cord-pressing block 5, steel rope 3 two ends connect the ring making steel rope 3 type become closed, steel rope 3 are stretched direct join and are fixed on crane span structure 4 both sides.
Steel rope 3 two ends are placed on pulley 2, and pulley 2 rotation is fixed on two pulley brackets before and after crane span structure service direction.
Before and after crane span structure 4 service direction, on the ground at pulley 2 place, fixing cord-pressing block 1 is fixedly housed between pulley 2 and crane span structure 4, on the downside of pulley 2, steel rope 3 is through fixing cord-pressing block 1 through hole.
The diameter of upper cord-pressing block 6 through hole, lower cord-pressing block 5 through hole and fixing cord-pressing block 1 through hole is all greater than 3 steel rope 3cm-4cm.
The present invention fixes steel rope by moving on line direction at crane span structure, and steel wire penetrating is fixed on the cord-pressing block on crane span structure, makes when crane span structure was subject to laterally crossing strong wind, when crane span structure will blow down, steel rope and cord-pressing block by generation angle, to ensure that crane span structure can not be blown down.
