Description

Traction trolley for ship unloader and anti-drop limiting carrier roller mechanism thereof

Technical Field

The utility model relates to the technical field of ship unloaders, in particular to a traction trolley for a ship unloader and an anti-drop limiting carrier roller mechanism thereof.

Background

The ship unloader is mainly used for continuously lifting bulk materials out of a ship cabin, then unloading the bulk materials to an arm support or a rack and conveying the bulk materials to a local conveyor system of a shore main conveyor, grabbing coal from the ship cabin through a four-rope double-jaw grab bucket suspended on a traction trolley, conveying the bulk materials to the position above a hopper through the trolley operation and lifting and opening-closing combined movement of the grab bucket, opening the grab bucket, and distributing the coal to two belt conveyors which are positioned at the rear side of a rear rail and parallel to a quay shore through a hopper, a vibrating feeder and a material switching device, wherein a sprinkling dust removing device is arranged at a hopper opening. When the ship unloader runs, the traction trolley is pulled by the steel wire rope to move along with the main trolley, the traction steel wire rope is supported and lifted by the supporting roller, and when the opening and closing steel wire rope moves, the lower supporting roller with supporting function and the upper supporting roller for inhibiting the steel wire rope from popping up are assembled by the supporting roller on the supporting rope trolley, so that the steel wire rope and other components are prevented from rubbing against each other, and meanwhile, the steel wire rope is prevented from sagging when no load exists, and the steel wire rope and other metal components are prevented from rubbing against each other. The pressing rope is provided with an upper limiting carrier roller, as shown in fig. 1, a carrier roller falling groove is formed in a lower base body in the prior art, a carrier roller shaft is arranged in the carrier roller falling groove, an upper anchor ear is arranged at a notch to prevent the carrier roller from falling off, but the upper anchor ear is fixed through a bolt, the upper anchor ear is easy to damage after long-term use of the bolt, the carrier roller falls off along with shaking of a ship body, and a great potential safety hazard is generated.

Disclosure of Invention

The utility model aims to provide a traction trolley for a ship unloader and an anti-drop limiting carrier roller mechanism thereof, wherein the traction trolley can effectively prevent carrier rollers from dropping.

In order to solve the technical problems, a first technical scheme adopted by the utility model is as follows: the utility model provides an anti-drop spacing bearing roller mechanism, has base and spacing bearing roller, be equipped with the anticreep groove on the base, the anticreep groove includes horizontal section and vertical section, the one end and the vertical section of horizontal section communicate with each other, and the other end is equipped with the anticreep end cap, the both ends of spacing bearing roller are adorned respectively in the anticreep groove of both sides base.

In the technical scheme, a falling alarm is arranged at the plug of the other end of the transverse section.

In order to solve the above problems, a second technical solution of the present utility model is: the traction trolley for the ship unloader comprises a frame, the anti-drop limiting carrier roller mechanisms are arranged on two sides of the frame, a pulley is arranged in the middle of the frame, and a traction steel wire rope passes through the anti-drop limiting carrier roller mechanisms and is arranged on the pulley.

In the technical scheme, both sides of frame all are equipped with the railing, anti-drop spacing bearing roller mechanism installs in the middle part of railing.

In summary, compared with the traditional technical means, the technical scheme provided by the utility model has the following beneficial effects: according to the utility model, the vertical falling groove is changed into the anti-falling groove formed by the transverse section and the vertical section, the limiting carrier roller is transversely pushed in and then vertically falls down to the falling groove, and double-insurance limiting is carried out through the anti-falling plug, so that the limiting carrier roller can be ensured not to fall off from the high altitude after being applied to the traction trolley, and the safety of the equipment in use is greatly improved.
