Abstract
The invention discloses a device for preventing a steel wire rope for fixed pulleys of a bridge crane from jumping from a slot, and aims to provide a device which is simple in structure and can effectively prevent wear to fixed pulley shafts and jumping-out-of-groove accidents due to lateral force and elastic force born by a steel wire rope. The device comprises rollers which are mounted on webs on two sides of a crane trolley, located above fixed pulley blocks and are perpendicular to the winding direction of the steel wire rope, and the distance between each roller and the fixed pulley blocks is 3-9 mm.
Description
Technical field
The present invention relates to a kind of crane in bridge type fixed pulley preventing wire rope from falling slot device.
Background technology
In the lifting mechanism of crane in bridge type, pulley support and the motion of guiding rope, play guiding and balance two effects.Assembly pulley wears winding by the movable pulley of some and fixed pulley to become, and it has the feature of movable and fixed pulley concurrently.Assembly pulley can change the direction of power again can be laborsaving.The assembly pulley be made up of steel rope, fixed pulley and movable pulley is the important component part of crane hoisting mechanism, is the dead sheave of suspension hook group cooperating, is fixed in structure.
The use of remote control crane is more prevalent, but the use of remote control crane exists problems and potential safety hazard, and particularly outstanding potential safety hazard is steel cable slot disengaging phenomenon, has become great potential safety hazard.
Analyze reason, the phenomenon of on-the-spot specific operation condition, cause lifting mechanism to be in and askewly skew the state of hanging, when the drift angle of steel rope discrepancy rope race is excessive (> 5 °), grooving sidewall will be subject to the effect of larger transverse force, easily makes notch damage, makes steel cable slot disengaging, and operating personal misoperation, make steel rope cause de-groove (see Fig. 1).
Pulley wire rope is de-groove repeatedly, or after steel cable slot disengaging, under operating personal unknown situation, still in manipulating crane operation, cause fixed pulley axis to wear and tear groove, and steel rope abrasion break stock, causes fixed pulley axis to rupture or the unexpected fracture accident of steel rope by the effect of weight pulling force under lifting mechanism hook.
The harm that steel cable slot disengaging causes:
1. steel rope is twisted together, bent, plastic deformation, hemp core are deviate from, whole stock fracture etc. is disposable scraps;
2. crane equipment causes damage;
3. increase service personnel working strength;
4. derailment of cable wire is as found not in time, very easily causes steel rope to break, drop in beam falls;
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of structure and simply, effectively prevents steel rope to be subject to transverse force and elastic force that the groove separation preventing device occurred wearing and tearing and the de-groove phenomenon accident of fixed pulley axis occurs.
For reaching above-mentioned purpose, a kind of crane in bridge type fixed pulley of the present invention preventing wire rope from falling slot device, described anti-bracket device comprises and is installed on monkey two coxostermum and is positioned at roller bearing vertical with steel rope spooling direction above fixed pulley group, and described roller bearing and described fixed pulley group distance are 3-9mm.
Wherein said monkey two coxostermum is upper is also provided with the described roller bearing vertical with described steel rope spooling direction below fixed pulley group, and described roller bearing and described fixed pulley group distance are 3-9mm.
Wherein said roller bearing and described fixed pulley group distance are 6mm.
Wherein said monkey two coxostermum is provided with bearing brackett, and described bearing brackett is provided with single row ball bearing, and described roller bearing is arranged between corresponding described single row ball bearing.
Wherein said bearing brackett and described roller bearing material are Q235A steel.
Crane in bridge type fixed pulley preventing wire rope from falling slot device difference from prior art of the present invention is that the present invention achieves following technique effect:
Groove separation preventing device of the present invention not only serves protective effect to pulley, sheave shaft; more avoid pulley wire rope because repeatedly taking off groove; or after steel cable slot disengaging; under operating personal unknown situation; still in manipulating crane operation, cause fixed pulley axis to wear and tear groove, and steel rope abrasion break stock; by the effect of weight pulling force under lifting mechanism hook, cause the generation of fixed pulley axis fracture or the unexpected fracture accident of steel rope
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing crane in bridge type fixed pulley steel rope without groove separation preventing device;
Fig. 2 is the structural representation of crane in bridge type fixed pulley preventing wire rope from falling slot device of the present invention.
Description of reference numerals: 1-fixed pulley group; 2-steel rope; 3-web; The anti-bracket device of 4-; 5-bearing brackett; 6-single row ball bearing; 7-roller bearing.
Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
As shown in Figure 2, a kind of crane in bridge type fixed pulley of the present invention preventing wire rope from falling slot device, anti-bracket device 4 comprise be installed on respectively monkey two coxostermum 3 upper and lower and be positioned at above fixed pulley group 1, roller bearing 7 that below is vertical with steel rope 2 spooling direction, roller bearing 7 and fixed pulley group 1 are apart from being 3-9mm, be preferably 6mm
In an embodiment, monkey two coxostermum 3 is provided with bearing brackett 5, and bearing brackett 5 is provided with single row ball bearing 6, and roller bearing 7 is arranged between corresponding single row ball bearing 6, and bearing props up, 5 and roller bearing 7 material be Q235A steel.
When pulley wire rope is subject to External Force Acting, occur instantaneously spring and when contacting with roller bearing, roller bearing can produce longitudinal resistance to steel rope, even if steel rope is come in and gone out during the drift angle > 5 ° of rope race, capital is subject to the rolling resistance of roller bearing, namely can not injure steel rope itself, also can prevent steel rope from occurring the wearing and tearing of fixed pulley axis and de-groove phenomenon accident by transverse force and elastic force generation
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
