Abstract
The utility model relates to a lifting device for a straightener, which comprises frames and rollers. The frames comprise an upper frame and a lower frame and the rollers comprise an upper roller and a lower roller. The upper frame is connected with the upper roller and the lower frame is connected with the lower roller. The lifting device also comprises sealing rings. The connection part of the upper roller and the upper frame is equipped with a sealing ring and the connection part of the lower roller and the lower frame is also equipped with a sealing ring. Since the lifting device is additionally equipped with the sealing rings, the dead locking of the rollers caused by oxide scales can be effectively avoided. Therefore, the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of straightener lowering or hoisting gear.
Background technology
In the prior art, straightener is to crooked stem, sucker rod and crooked seamless steel pipe, the special equipment that tubing and casing is carried out straightening processing, wherein up-down rollers will be done suitably to adjust according to steel pipe sizes and material behavior, oxidized pick up extremely can not normally be adjusted when but the straightener poor working environment often caused roll to adjust, and influenced ordinary production.
Summary of the invention
At above-mentioned shortcoming, the utility model technical issues that need to address provide a kind of straightener lowering or hoisting gear.
The technical solution adopted in the utility model is:
The straightener lowering or hoisting gear, comprise frame and roll, described frame comprises upper spider and lower bearing bracket, described roll comprises topping roll and bottom roll, described upper spider is connected with topping roll, and described lower bearing bracket is connected with bottom roll, also comprises sealing ring, described topping roll and upper spider junction are provided with sealing ring, and described bottom roll and lower bearing bracket junction are provided with sealing ring.
The utility model has the advantages that: increased sealing ring, prevented that effectively the oxidized pick up of roll is dead, improved production efficiency.
Description of drawings
