By using the guiding device, the fault probability caused by rope climbing and rope disordering of the steel wire rope is reduced, and the maintenance cost is effectively reduced.

Description

A kind of guide piece for optimizing Steel wire rope discharge angle
Technical field
The design relates to a kind of guide piece for optimizing Steel wire rope discharge angle, belongs to lifting technique field.
Background technology
Crawler crane belongs to runabout crane, and it is contained on caterpillar chassis by hoisting operation part, relies on the construction machinery and equipment of crawler attachment walking, in being mainly applicable to, the lifting operation of heavy construction.Crawler crane has four great institutions: lifting mechanism, luffing mechanism, swing type mechanism and traveling gear, by the action that cooperatively interacts of these mechanisms, can complete the lifting operation of different operating mode.
The lifting operation of crawler crane needs to be realized by steel rope and hoisting sheave.Steel rope one ends wound is being fixed on the reel in turntable, and the other end is connected with suspension hook by the hoisting sheave on jib top.When reductor band movable reel rotates, the rope closing of steel rope can be realized and put rope action.When steel rope is arranged on reel, demand fulfillment elevation angle is within the scope of 0.5 ° ~ 1.5 °, and so-called elevation angle is the drift angle that steel rope departs from jib longitudinal plane of symmetry, as the α in Fig. 1.When short principal arm rope stretching, elevation angle is greater than 1.5 °, cannot ensure into groove, cause disorder cable, as shown in Figure 2 when easily causing steel rope to be arranged on drum rope groove; When long principal arm rope stretching, when elevation angle is less than 0.5 °, when steel rope is discharged to reel side, often cannot enters second layer grooving smoothly, but up arrange along mandrel wall always, thus cause the fault of rope climbing, as shown in Figure 3.
By reasonably selecting reel home record carpenters square cun and the position of principal arm arm head leading sheave, can ensure that the elevation angle when principal arm galianconism is less than 1.5 °, thus disorder cable problem when avoiding steel rope to be wound around on reel.And during for middle long principal arm operating mode, because arm head leading sheave and reel are apart from excessive, Steel wire rope discharge angle often cannot ensure the requirement being greater than 0.5 °.For this problem, the scheme that each producer current is all not good solves.
Summary of the invention
For the deficiencies in the prior art, the object of the design is to provide a kind of guide piece for optimizing Steel wire rope discharge angle, be loaded on jib middle node during work, strengthen the rope stretching angle of steel rope when reel both sides end position, thus realize the smooth winding of elevator.The position of rational layout guide piece, make Steel wire rope discharge angle in remain within rational scope in long-armed length range.By the use of this device, reduce steel rope due to rope climbing, disorder cable and out of order probability, effectively reduce maintenance cost.
For achieving the above object, the design is realized by following technological means:

Described a kind of guide piece for optimizing Steel wire rope discharge angle, is characterized in that: described support and jib are by being welded to connect.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, it is characterized in that: described wire line guide is made up of roller, pulley, support, described support is U-shaped structure, described roller, pulley are arranged in support U-shaped structure by rotating shaft successively, gap between described roller, pulley is greater than the diameter of steel rope, connects the gap between the steel wire penetrating roller of reel and hoisting sheave and pulley.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, is characterized in that: the material of described small sheave, roller, pulley is nylon.
The invention has the beneficial effects as follows: the fabricated wire line guide of one provided by the invention, be loaded on principal arm middle node during work, strengthen the rope stretching angle of steel rope when reel both sides end position, thus realize the smooth winding of elevator.The position of rational layout guide piece, make Steel wire rope discharge angle in remain within rational scope in long-armed length range.By the use of this device, reduce steel rope due to rope climbing, disorder cable and out of order probability, effectively reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is elevation angle schematic diagram, and Fig. 2 is short principal arm rope stretching disorder cable condition diagram, and Fig. 3 is long principal arm rope stretching rope stretching rope climbing condition diagram, and Fig. 4 is that the design forms structural representation, and Fig. 5 is guide piece structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As Fig. 1--shown in 5, a kind of guide piece for optimizing Steel wire rope discharge angle, comprise reel 1, jib 3, the hoisting sheave 2 on jib top and the steel rope 4 of connection reel and hoisting sheave, it is characterized in that: the jib 3 between reel 1 and hoisting sheave 2 is also provided with wire line guide 5.
Further:
Described a kind of guide piece for optimizing Steel wire rope discharge angle, it is characterized in that: described wire line guide 5 is made up of small sheave 6, pulley 7, support 8, described support 8 is U-shaped structure, described small sheave 6, pulley 7 are arranged in the U-shaped structure of support 8 by rotating shaft successively, gap between described small sheave 6, pulley 7 is greater than the diameter of steel rope 4, connects the steel rope 4 of reel 1 and hoisting sheave 2 through the gap small sheave 6 and pulley 7.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, is characterized in that: be provided with adapter plate bottom described support 7, adapter plate is connected with jib 3 by bolt.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, is characterized in that: described support 8 and jib 3 are by being welded to connect.
During concrete enforcement, also small sheave 6 can be replaced with the guide frames such as roller, identical technique effect can be played.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, it is characterized in that: described wire line guide 5 is made up of roller, pulley 7, support 8, described support 8 is U-shaped structure, described roller, pulley 7 are arranged in support 8U shape structure by rotating shaft successively, gap between described roller, pulley 7 is greater than the diameter of steel rope 4, connects the steel rope 4 of reel 1 and hoisting sheave 2 through the gap roller and pulley 7.
Described a kind of guide piece for optimizing Steel wire rope discharge angle, is characterized in that: the material of described small sheave 6, roller, pulley 7 is nylon.
As shown in Figure 1, Steel wire rope discharge angle α is:
α=tan(H/2L)
In formula: H is for promoting winding reel home record distance degree;
L is the distance that spool axis arrives hoisting sheave axis.
When jib length is longer, hoisting sheave and hoisting drum distance very large (namely L numerical value is larger), now, elevation angle α will be less than 0.5 °.The present invention certain position on jib (this position is between reel and hoisting sheave) increases wire line guide, forces steel rope by this guide piece, to change the elevation angle of steel wire horizontal stroke.Because the spacing of guide piece and reel is less than hoisting sheave and reel distance, as shown in Figure 4, therefore, now elevation angle will be less than former elevation angle α.The position of rational layout guide piece, meets making hoist rope elevation angle the requirement being greater than 0.5 ° all the time.
When jib length is shorter, mounting hole can be provided with on support base plate, be fixed in the nutplate of jib by bolt when needing; When jib does not need guide piece, can be pulled down, simple to operate.
To longer jib, by the jib of guide piece support welding, can not need dismounting yet, save working hour.
