Walking wheel mechanism of suspended cover manipulator

Abstract

The invention discloses a walking wheel mechanism of a suspended cover manipulator. Wheel shafts are step shafts; wheels are mounted on the wheel shafts; bearings are arranged between the wheel shaftsand hubs of the wheels; the end parts of the wheel shafts penetrate through the bearings; threads are arranged on the peripheral surfaces, near the end parts, of the wheel shafts; nuts are connectedto the threads of the wheel shafts for pressing one ends of inner rings of the bearings; step end surfaces of the wheel shafts are pressed by the other end surfaces of the inner rings of the bearings;one ends of the wheels are connected with stifles; one end surfaces of outer rings of the bearings are pressed by the stifles; and the other end surfaces of the outer rings of the bearings are tightly pressed on the hubs. The nuts are used for axially positioning one ends of the inner rings of the bearings; the step end surfaces of the step shafts are used for axially positioning the other ends of the inner rings of the bearings; and the nuts and the wheel shafts are in threaded fit connection, so that the axial acting force of the bearings is increased, the axial bearing capacity of the wheels is improved, the deflection falling of walking wheels caused by looseness of the walking wheels is prevented, and the machining and assembly difficulty of the wheels is reduced.

Description

technical field [0001] The invention belongs to the field of capping machines, and in particular relates to a traveling wheel mechanism of a suspended capping machine. Background technique [0002] At present, the uncapping machine is one of the main equipment widely used in front of the blast furnace. The main function of the uncapping machine is to remove the main ditch cover laid on the main iron ditch when it is necessary to open the plugging operation, so that other equipment can complete the corresponding opening and plugging work. [0003] The full-hydraulic suspension uncapping machine hangs the main body of the uncapping machine on the straight-line walking track under the tuyere platform through four traveling wheels, and then uses the walking cylinder to drive the wheels to reciprocate on the track to realize the removal and maintenance of the main ditch cover. reset. During the working process of the uncapping machine, it is necessary to move the ditch cover we...

AI Technical Summary

Problems solved by technology

During the working process of the uncapping machine, it is necessary to move the ditch cover weighing about 16-18t for a distance of about 4000mm. The main body is suspended on the straight-line walking track under the tuyere platform, so it is inevitable that the walking wheels will become loose due to structural deformation and differences in the flatness of the track laying, which will lead to the deflection and falling off of the walking wheels
