Abstract
The utility model relates to a translating pulley block which comprises a pulley end cover (1), a shaft sleeve (2), a pulley shaft (3) and a pulley yoke (5). The pulley shaft (3) is sleeved with the shaft sleeve (2). The translating pulley block is characterized in that the two ends of the pulley shaft (3) are provided with shaft end glands (4), the shaft end glands (4) and the shaft sleeve (2) extrude each other, the end faces are sealed through a seal strip. The shaft end glands (4), the shaft sleeve (2) and an inner bearing ring are fixed through mutual extrusion, abrasion between the shaft end glands (4), the shaft sleeve (2) and the inner bearing ring is reduced, use efficiency is improved, and cost is greatly saved. When the pulley shaft needs to be replaced, the shaft end glands (4) at the two ends of the pulley shaft (3) only need to be disassembled, and the pulley shaft (3) is easily separated from a bearing. The translating pulley block is convenient, fast, time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of traversing sheave block, the traversing sheave block that is specifically used for Shipping location or turns to.
Background technique
Need article hoisting after hull pulls in to shore time, hull is fixed with anchor, the lifting device on ship carries out object handling, because the position of object is unfixed, often will enable traversing sheave block and adjust position and the direction of handling.
At present, the bearing of traversing sheave block is directly enclosed within outside pulley spindle, very close to each other between them, axle sleeve is in During Process of Long-term Operation, easily produce and become flexible, between axle sleeve and pulley spindle, occur matching gap, cause the wearing and tearing of axle sleeve, cause the distortion of axle sleeve, and in the time changing pulley spindle, be difficult to dismounting, time-consuming effort again, easily produce and damage, cause unnecessary waste.
Summary of the invention
For above problem, the utility model provides a kind of traversing sheave block, and it is to be provided with axle head gland at the two ends of pulley spindle, pushes pulley axle sleeve and bearing inner race, makes not rotate between them, thereby reaches sealing and fixing effect.
For reaching above object, the utility model has adopted following technological scheme: a kind of traversing sheave block, comprise pulley end cap, axle sleeve, pulley spindle, pulley frame, pulley spindle is arranged with axle sleeve outward, the two ends of described pulley spindle are provided with axle head gland, axle head gland pushes mutually with end face of shaft bush, and end face seals by Stamping Steel Ribbon.
Axle head gland described in the utility model is bolted on pulley frame; Described axle head gland is metallic material.
Adopt after above technological scheme, a kind of traversing sheave block of the utility model, owing to being provided with axle head gland at the two ends of pulley spindle, between axle head gland and axle sleeve, bearing inner race, extruding is fixing mutually, the wearing and tearing between them are reduced, extend utilization efficiency, greatly provided cost savings, while needing to change pulley spindle, as long as the axle head gland at pulley spindle two ends is unloaded, pulley spindle is easy to separate with bearing, convenient and swift, has not only saved time, but also laborsaving.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Fig. 1, a kind of traversing sheave block, comprises pulley end cap 1, axle sleeve 2, pulley spindle 3, pulley frame 5, the outer axle sleeve 2 that is arranged with of pulley spindle 3, the two ends of described pulley spindle 3 are provided with axle head gland 4, and axle head gland 4 pushes mutually with axle sleeve 2 end faces, and end face seals by Stamping Steel Ribbon.
Axle head gland 4 described in the utility model is bolted on pulley frame 5; Described axle head gland 4 is metallic material.
A kind of traversing sheave block of the utility model, between bearing and pulley spindle 3, leave gap, axle head gland 4 by pulley spindle 3 two ends pushes axle sleeve 2, axle sleeve 2 pushes the end face of bearing inner race again, and bearing inner race is not rotated with respect to pulley spindle 3, and seal ring is installed simultaneously between them, make seawater can not enter into bearing, good airproof performance, has reduced wearing and tearing, cost-saving.
A kind of traversing sheave block of the utility model play the guiding role on lifting device, bears stressedly, utilizes sheave block traction object, not only can be laborsaving, and can like a cork more object be delivered to destination, energy saving.
