Movable special vehicle for dismantling liner bolts of large mills

Abstract

The invention discloses a movable special vehicle for removing bolts from a lining plate of a large-sized mill. The movable special vehicle comprises a left longitudinal beam and a right longitudinal beam which are arranged in parallel along the front and back direction; the left longitudinal beam and the right longitudinal beam are connected through a cross beam; the rear side of the cross beam is provided with a hydraulic power station and a driving control board; the front side of the cross beam is provided with a support; the left side and the right side of the support are respectively provided with a steering wheel; a hydraulic steering system for controlling the two steering wheels to steer simultaneously is arranged in the support; the front end of the left longitudinal beam and the front end of the right longitudinal beam are respectively provided with a driving wheel; the center of each driving wheel is in transmission connection with a hydraulic travel motor; the right side of the front end of the left longitudinal beam is provided with a left jacking hydraulic cylinder; the left side of the front end of the right longitudinal beam is provided with a right jacking hydraulic cylinder; a framework is arranged on the left jacking hydraulic cylinder and the right jacking hydraulic cylinder; the framework is provided with a bolt removal mechanism. The movable special vehicle disclosed by the invention is capable of performing actions of free steering, travelling, lining plate bolt removal and the like according to the condition of the actual site, and therefore the labor strength of a worker is fully reduced, and the removal efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of special equipment for maintenance of large mills, and in particular relates to a movable special vehicle for removing liner bolts of large mills. Background technique [0002] The traditional large-scale mills mainly adopt the method of manually coordinating driving with driving. Due to the limitation of the workshop, some enterprises cannot use driving. They can only use purely manual methods to remove the bolts on the liner of the mill. Due to long-term operations, the grinding The liner installed on the inner wall of the machine drum will be smashed, which requires regular replacement of the liner. The liner is fixed to the inner wall of the mill drum by bolts, and the bolts will also corrode or deform along with the liner. When changing the liner, the bolts must be removed first. Bolts are pierced from the inside to the outside, and there are nuts on the outer ends of the bolts. When removing the bo...

AI Technical Summary

Problems solved by technology

Bolts are pierced from the inside to the outside, and there are nuts on the outer ends of the bolts. When removing the bolts, first remove the nuts, and then drive the bolts inwards. Manual work is not only labor-intensive, but also prolongs the large-scale operation to a large extent. The time for mill maintenance is reduced, and the safety of construction is also reduced
