Abstract

The utility model relates to a pothook steel wire rope slide wheel shield, in particular to a pothook steel wire rope slide wheel shield which can decrease the wear of the steel wire ropes and is able to dismantle the high rigidity. The utility model primary solves the technical problem that the friction of the steel wire rope and the slide shield results in the easy damage of the pothook slide shield. The technical proposal of the utility model is that: the pothook steel wire rope slide wheel shield, which can reduce the friction, consists of a slide, a slide shaft and a shield. The slide is sheathed to the slide shaft fixed on the shield. The utility model is characterized in that the shield is a semi-enclosure type consisting of a side plate and a shield, between which an arch shield is put and a buckle groove is positioned and linked between the side plate and the shield. A plurality of the bolt holes are opened along the round arc on the end part of the side plate and the bolt holes on the two sides are corresponded to each other. A long bolt is used to fix the connection between the sides and a shaft sleeve is installed on the bolt. The utility model is primary used to prevent the friction of the pothook steel wire rope slide wheel shield and the steel wire rope when the automobile is driving.

Description

But the suspension hook wire rope pulley case of anti-attrition

Technical field:

The utility model relates to a kind of suspension hook wire rope pulley case, particularly a kind of suspension hook wire rope pulley case that reduces the high rigidity of detouchable of steel rope abrasion.

Background technology:

Pulley on the travelling crane hook is to be used for changing the steel rope sense of motion, and can form assembly pulley to reach the labour-saving purpose.The pulley at suspension hook place can only rotate around sheave shaft, and sheave shaft is motionless.And during the travelling crane hook normal operation, the pulley case usually causes the deformed damaged of pulley case because of the friction in the steel rope operational process, causes production normally not carry out, and because wearing and tearing cause rope service-life to shorten greatly.Need to design a kind of later-model steel rope case in the production to guarantee that travelling crane hook normally uses.Chinese patent CN95210618.3 discloses a kind of " the suspension hook group of the totally-enclosed case of compound type ", comprise suspension hook, pulley, pulley and axle all install in the compound type fully enclosed case of a column type, case is formed by three, the connection place of per two cases, the outside relies on flange to fix, and is inboard by the seam engagement.By its structure as can be seen, this patent also can't be avoided the friction of steel rope and pulley case.

Summary of the invention:

The purpose of this utility model provides a kind of steel rope abrasion that reduces; and be the suspension hook wire rope pulley case of the high rigidity of detouchable; prolong the service life of steel rope and pulley case; guarantee the travelling crane hook safe and stable operation, guarantee that driving does not cause the shutdown of producing because of the suspension hook fault.The friction that mainly solves steel rope and pulley case causes the damageable technical matters of lifting hook pulley case.The technical solution of the utility model is: but the suspension hook wire rope pulley case of anti-attrition comprises pulley, sheave shaft and case, and pulley sleeve is connected on the sheave shaft, sheave shaft is fixed on the case, it is characterized in that case is semi-enclosed, is made up of side plate and cover plate, be the cover plate of arc between two blocks of side plates, for the catching groove location connects, side end has a plurality of bolts hole along circular arc between side plate and the cover plate, and the bolt hole of biside plate is correspondence mutually, with elongated bolt, axle sleeve is housed on the bolt between the side plate.

Effect of the present utility model is: the side plate of case, cover plate adopt the steel plate of the above thickness of 12mm to be made, and the assurance case keeps certain rigidity indeformable when steel rope moves up and down; In addition owing to adopt elongated tie bolt to connect case both sides side plate, when making the wire rope pulley of suspension hook or case et out of order since the bolt of case be easy to dismantle keep in repair convenient; Machine two is thin in the middle of the more important thing is tie bolt; rely on the step positioning housing at bolt two ends; on bolted connection, increased axle sleeve; make the rotary resistance of axle sleeve reduce; axle sleeve and housing leave the gap, when the steel rope up-and-down movement, are the axle sleeves that is easy to change because steel rope rubs; utilize maintenance periodic replacement axle sleeve, thereby the protection shroud body is not worn.More than three promises the needs of travelling crane hook normal operation.

Description of drawings:

Accompanying drawing is the utility model structural representation:

Among the figure: 1-pulley, 2-sheave shaft, 3-steel rope, 4-side plate, 5-tie bolt, 6-axle sleeve, 7-nut, 8-cover plate, 9-catching groove.

The specific embodiment:

Referring to accompanying drawing, sheave shaft 2 is fixed together with the suspension hook transverse axis, and pulley 1 is around sheave shaft 2 revolutions, and steel rope 3 links to each other with the assembly pulley of suspension hook top on pulley 1.The side plate 4 and the sheave shaft 2 of case are fixed together, and its inboard is provided with the catching groove 9 that prevents the relative changing of the relative positions of cover plate, and cover plate 8 bends to semicircular arc, is embedded between two blocks of side plates, 4 catching grooves 9.Two side plate 4 opposite positions have the bolt hole of 6 φ 26, tie bolt 5 passes the right side plate 4, captive joint with nut 7 with left side side plate 4, tie bolt 5 two ends screw threads are M24, middle polished rod part φ 30, the axle sleeve 6 of φ 39 (thick 4mm) is housed on the polished rod of φ 30, and the axle sleeve length overall is than the partly short 2mm of polished rod.Side plate 4 is installed from tie bolt 5 two ends, relies on φ 30 polished rod steps that two end side panels is located.

The oscilaltion of suspension hook hoisting heavy is to rely on the motion that is connected the steel rope 3 on the pulley 1 to realize.The motion of steel rope 3 drives pulley 1 and rotates around sheave shaft 2, realizes moving up and down of sheave shaft 2 simultaneously, that is to say, in the process of suspension hook up-and-down movement, pulley 1 has rotation and upper and lower displacement simultaneously.Because steel rope 3 has intensity height, flexible good characteristics, steel rope 3 can be jumped out pulley groove in the up-and-down movement process, with axle sleeve 6 grazings on the bolt 5, because axle sleeve 6 has the 2mm gaps, with tie bolt 5 the 2mm gap is arranged diametrically in axial and two end side panels 4, thereby along with the up-and-down movement of steel rope 3, axle sleeve 6 rotates around bolt 5 under the drive of steel rope 3, can reduce friction force between steel rope 3 and the case cover plate 8, thereby reduces the wearing and tearing of steel rope 3 and case cover plate 8.

Side plate 4 and cover plate 8 adopt 12mm to be made with upper steel plate, to the side plate location of the step between the two ends to two ends, can guarantee the unlikely distortion of rigidity of case in the middle of the tie bolt 5.Side plate 4 inboards are provided with the catching groove 9 that prevents the cover plate 8 relative changing of the relative positions, semicircle cover plate 8 is embedded between two blocks of side plates, 4 catching grooves 9, and adopt the bolt 5 of 6 M24 to connect between two blocks of side plates 4, can guarantee that whole case is easy to dismounting in the maintaining process, make things convenient for the maintenance of case and even suspension hook group.
