Brake structure for large-sized oil tanker deck trolley

Abstract

The invention belongs to the technical field of ships and relates to a large-sized oil tanker, in particular to a brake structure for a large-sized oil tanker deck trolley. The brake structure for the large-sized oil tanker deck trolley comprises a guideway, a conveying platform, a locating groove, a fixing rod, a circular disc, a handrail, a roller I, clamping arms, a roller II, pressing springs, a brake rod, a return spring, a brake pad, a fixing sleeve, a pedal plate and a locating ring; the guideway, which is distributed in an annular shape, is laid on an oil tanker deck; the deck trolley is arranged on the guideway; the deck trolley comprises the conveying platform, which is arranged on the guideway; the brake structure comprises the brake rod and the return spring; a through hole, which is aligned with the upper surface of the guideway, is formed in the conveying platform; the brake rod penetrates through the through hole; the brake pad is fixed at the lower end of the brake rod; the pedal plate is fixed at the upper end of the brake rod; the return spring sleeves the brake rod; and the return spring is arranged between the pedal plate and the conveying platform so that the brake pad has a tendency of always moving far away from the guideway.

Description

technical field [0001] The invention belongs to the technical field of ships, and relates to a large oil tanker, in particular to a brake structure for a deck trolley of a large oil tanker. Background technique [0002] With the rapid development of global trade, the demand for global logistics is also increasing, especially for crude oil, a product with huge demand. Crude oil is generally transported by oil tankers. In order to increase the transport capacity of oil tankers, oil tankers are now being built larger and larger, which leads to very large and long decks of oil tankers. Various pipelines are generally laid on the deck of oil tankers. There are various instruments, and these instruments need to be tested during the voyage, which requires personnel to patrol the deck. At present, the way of walking is used, resulting in low efficiency. Therefore, the way of deck trolley is used to facilitate movement.

Crude oil is generally transported by oil tankers. In order to increase the transport capacity of oil tankers, oil tankers are now being built larger and larger, which leads to very large and long decks of oil tankers. Various pipelines are generally laid on the deck of oil tankers. There are various instruments, and these instruments need to be tested during the voyage, which requires personnel to patrol the deck. At present, the way of walking is used, resulting in low efficiency. Therefore, the way of deck trolley is used to facilitate movement. The current deck trolley structure It is more complicated, especially the brake structure is more complicated. Due to the harsh offshore environment, especially the corrosion of seawater, it is not suitable for long-term use in the offshore environment.
