Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] In the present invention, unless otherwise stated, the used orientation words such as "up, down, left, and right" generally refer to up, down, left, and right in the drawings.

[0037] see Figure 1 to Figure 3 , the ship loader usually includes a mast 1 and a cantilever 2, the tail of the cantilever 2 is hinged to the mast 1 through a pin 3, and a bearing 4 is sleeved on the pin 3, more specifically, the bearing 4 is installed In the lug plate of door frame 1. Depend on image 3 It can be seen that the pin shaft 3 is mainly subjected to the force of the cantilever 2 . Therefore, in order to be able to replace worn bearings with new ones to improve th...

Abstract

The invention discloses a ship loader pitching hinge point bearing replacement method. A ship loader comprises a portal frame (1) and a boom (2), the tail of the boom is hinged to the portal frame through pin shafts (3), and a bearing (4) sleeves each pin shaft. The replacement method includes: firstly, placing the boom at a horizontal position; secondly, arranging a pushing device (2) on the portal frame, and pushing the tail of the boom through the pushing device so as to eliminate force borne by the pin shafts; thirdly, detaching the pin shafts, and then replacing the bearings prior to mounting the pin shafts; fourthly, detaching and removing the pushing device. The boom is placed at the horizontal position, the tail of the boom is pushed to eliminate acting force applied by the boom to the pin shafts, then the pin shafts are detached and the bearings are replaced, so that bearing replacement difficulty can be lowered, replacement efficiency is improved, and working reliability of a ship loader pitching mechanism can be improved.

Description

technical field [0001] The invention relates to the field of ship loaders, in particular to a method for replacing a pitch hinge point bearing of a ship loader. Background technique [0002] A ship loader is a common piece of equipment used to load cargo onto ships in ports. Usually, a ship loader includes multiple parts such as a gantry, a tower, a pitching device, a traveling device, and a belt conveyor. [0003] Wherein, the pitching device includes a cantilever. In the current ship loading operation, due to the long-term operation of the cantilever of the ship loader, the bearing at the hinge point of the cantilever is severely worn, resulting in an increase in the gap between the bearing and the boom, and even the inner and outer rings of the bearing are completely broken and damaged. In this case, the bearing at the hinge point of the cantilever needs to be replaced. Contents of the invention [0004] The purpose of the present invention is to provide a method for...
