Technical Field

The invention belongs to the field of rail hoisting and ship unloading, and particularly relates to a trolley for rail hoisting and ship unloading and a rail hoisting and ship unloading method.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

A track crane is also called a track crane, and refers to an operation type crane which is to be detached and reinstalled when the crane runs on a track laid along the ground and is transferred to a work site. As a widely used port machine, it is generally transported by water from a manufacturing plant to a user terminal, and thus it is required to load and unload it on a ship. At present, the existing trolley for port mechanical loading and unloading ships is mainly of a four-wheel self-lifting type, two groups of trolleys with two wheels are connected with a hinge point of a balance beam, and the upper part of the balance beam is connected with a C-shaped hinge point of a connecting support; the walking trolley is converted into a state of 90 degrees with the working state (90 degrees with a wharf shoreline) through jacking before shipment, and then shipment and transportation are carried out; after the movable platform is unloaded to a wharf of a user, the movable platform is jacked again, and the walking is recovered to a working state parallel to a wharf shoreline.

However, the inventor believes that the conventional trolley for assisting the loading and unloading of the rail crane has the following defects: 1. the integral structure is heavy in self weight, and the requirement on the performance of hoisting and transferring equipment is high; 2. the jacking system has many wearing parts and is difficult to maintain; 3. the lateral bending moment resistance is small, and the risk in the ship loading process is high. Meanwhile, the existing trolley is high in manufacturing cost, and the requirement of the rail crane manufactured in batches is large.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the trolley for track hoisting and unloading and the track hoisting and unloading method, which have large lateral bending moment resistance, can adapt to uneven road surfaces, can allow the trolley to have large asynchronous deviation range, and are particularly suitable for roll-on transportation of a large-gauge rigid support leg track hoisting machine.

In order to achieve the purpose, the invention is realized by the following technical scheme:

in a first aspect, the technical scheme of the invention provides a trolley for rail hoisting and unloading, which comprises wheels, a trolley frame, a hinge point support and a connecting support, wherein the wheels are rotatably arranged on the side part of the trolley frame, the hinge point support is hinged to the middle part of the trolley frame, the wheels and the hinge point support are both connected with a shaft penetrating through the trolley frame, the hinge point support can rotate around a hinge point, the top surface of the hinge point support is erected on the trolley frame, and the connecting support is connected with the top surface of the hinge point support.

In a second aspect, the technical solution of the present invention further provides a rail hoisting and unloading method, using the trolley for rail hoisting and unloading ship as described in the first aspect, including the following steps:

the trolley equipment is in contact with the temporary running track for the loading and unloading ship, and the whole cart running mechanism of the track crane is suspended;

the track crane is dragged by the winch, and the trolley equipment is integrally rolled on and off to get on and off the ship;

in the loading and unloading process, the winch applies forward traction force to the trolley frame, and the wheels roll forward relative to the temporary track;

when the temporary running track surface is not flat, the trolley frame rotates around the hinge point shaft to keep the wheel tread surface in contact with the temporary track;

when the wheels of the trolley equipment run asynchronously, the wheel rims of the wheels can stop the wheels from derailing, and the traction speed of each trolley is adjusted to keep synchronous.

The technical scheme of the invention has the following beneficial effects:

1) compared with the existing structure, the invention has the advantages that the number of components is reduced, the self weight of the whole structure is reduced, and the performance requirement on hoisting and transferring equipment is lowered; meanwhile, the number of wearing parts of the jacking system is large, and maintenance is difficult, so that the number of components is reduced, the shaft body is convenient to disassemble, and maintenance is easier.

2) According to the mechanism adopted by the invention, the hinge point shaft and the wheel shaft penetrate through the trolley frame, so that the lateral bending moment resistance of the trolley frame is increased, and the risk in the shipping process is reduced.

3) The mechanism adopted in the invention is low in trolley manufacturing cost and convenient for mass production.

4) According to the invention, the hinged support is adopted, so that the shaking can be reduced through hinged swinging under the condition of uneven road surface.
