Problems solved by technology

With this installation structure, after the roller bracket is installed on the track 9, because the baffle is too close to the track elevation, there is no room for disassembly (the screws on the baffle cannot be removed), and even if the baffle is removed, it is difficult to install the circlip. Dismantle and remove the shaft from the bearing
In this way, after the roller mechanism is installed, it is inconvenient to disassemble and maintain.

Abstract

The invention discloses a dismountable rolling wheel mechanism for a ship rail crane. The dismountable rolling wheel mechanism comprises a rolling wheel, a support frame, a bearing seat, a bearing, ashaft and a positioning sleeve, wherein one side of the bearing seat is fixedly connected with the support frame; a baffle plate is fixed in an opening part of the bearing seat; the bearing sleeves the shaft and is fixed on the bearing seat through a bearing support; the positioning sleeve is arranged between the bearing and the bearing seat; the rolling wheel sleeves the end part of the shaft. The arrangement and installation of the bearing and the baffle plate and the shaft positioning are greatly improved; the arrangement and installation of the bearing on the rolling wheel is changed intothe installation on the support frame; the baffle plate is arranged at the outer side of the support frame; the positioning sleeve is added between the bearing seat and the bearing; the positioning sleeve is fixed on the bearing seat through screws; an outer ring of the bearing and an inner ring of the positioning sleeve are in transition matching; the shaft passes through the bearing and is theninserted into the rolling wheel; the shaft is connected with and fixed to the rolling wheel through two long screws, so that the shaft and the rolling wheel rotate together. The installing structure is safe and reliable; the dismounting, the mounting and the maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of a marine rail crane, in particular to a detachable roller mechanism of a marine rail crane. Background technique [0002] Such as figure 1 Shown, the label in the figure: baffle, scroll wheel, bushing, bracket, axis, circlip, screw, bearings, track rack. When installing the existing roller mechanism, the bushing 3 and the bracket 4 are fixed by welding, the shaft 5 and the bracket 4 are fixed by bolts, the shaft 5 does not rotate, the bearing 8 is installed inside the roller 2, and the baffle 1 is installed on the roller The end face is connected and fixed by screws 7 and is close to the track elevation, and the shaft 5 and the bearing 8 are connected by a circlip. With this installation structure, after the roller bracket is installed on the track 9, because the baffle is too close to the track elevation, there is no room for disassembly (the screws on the baffle cannot be removed),...
