Description

Simple berthing loading and unloading structure for sand and stone wharf

Technical Field

The application relates to the technical field of dock loading and unloading structures, in particular to a simple berthing loading and unloading structure of a sand and stone material dock.

Background

The sand and stone wharf is used for loading, unloading, storing, processing, selling sand and stone and other articles, and the wharf body is arranged at intervals with land areas and is connected through an approach bridge. The movable ship unloading equipment is used for unloading sand and stone materials in the cargo ship to the front belt conveyor, and the front belt conveyor is arranged along the length direction of the wharf and used for transporting the sand and stone materials in the sand ship to the transfer station. A shore-based belt conveyor is arranged between the transfer station and the land area and is used for conveying sand and stone materials of the transfer station to the land area. That is, when the ship transporting the sand and stone is leveled at the dock, the sand and stone is discharged to the transfer station on the dock, and then transported from the transfer station to the land by the shore-based belt conveyor.

With the progressive development of cargo ships, self-unloading sand carriers are increasingly used in transportation. The self-unloading sand ship is a novel multifunctional ship integrating sand transportation and sand unloading, and a bow belt conveyor for unloading sand and stone materials in a material cabin is arranged on the sand ship.

However, in practical use, the bow belt conveyor is not convenient enough to be matched with the existing front edge belt conveyor and the mobile ship unloading equipment, and the length of the bow belt conveyor extending out of the bow is not enough to directly transport sand and stone materials to land, so that a traditional unloading mode is often adopted, and the bow belt conveyor with higher self-unloading efficiency is idle.

Disclosure of Invention

In order to improve among the above-mentioned technique self-discharging sand ship still adopts traditional unloading mode after the pier berth, has led to the higher problem of ship bow belt feeder of self-discharging ship self-discharging efficiency to be by idle, this application provides a simple and easy berthing loading and unloading structure of grit material pier.

The application provides a simple and easy berthing loading and unloading structure of grit material pier adopts following technical scheme:

the utility model provides a simple and easy berth loading and unloading structure of grit material pier, includes the pier body and with pier body coupling's approach bridge, the one end of approach bridge is connected to land, the one end that the land was kept away from to the approach bridge is to keeping away from the direction in land extends the setting and outstanding in the pier body, the approach bridge outstanding in the one end of pier body is provided with the hopper that is used for accepting the sand and stones in the self-discharging sand ship, be provided with the bank-based belt feeder on the approach bridge, the one end of bank-based belt feeder set up in the below of hopper, the other end extends to land.

Through adopting above-mentioned technical scheme, when self-discharging sand ship is flat back at the pier, its own bow belt feeder is towards the approach bridge, and bow belt feeder inclines to the top and sets up and the top corresponds with the hopper. Then, the bow belt conveyor is started, sand and stone materials in the sand ship are gradually conveyed into the hopper by the bow belt conveyor, and then fall from a feed opening of the hopper to fall on the shore-based belt conveyor. Then, the land-based belt conveyor conveys the sand and gravel materials to the land area, so that the sand and gravel materials are discharged. This application has given a mounting platform of hopper and bank base belt feeder through the one end protrusion with the approach bridge in pier body setting to make the ship bow belt feeder of self-discharging sand ship have the butt joint end of unloading, compare in traditional mode of unloading, required transport structure needs to retrench more, and the mode of unloading is more direct and efficient.

Preferably, the pier body may be a discontinuous pier body.

By adopting the technical scheme, the construction cost of the wharf can be further reduced, and the wharf can be adapted to various water area environments.

Preferably, the hopper comprises a funnel-shaped blanking part and a frame body for bearing the blanking part, a baffle is arranged on the opening wall of the blanking opening of the blanking part in a downward extending mode, and the frame body is arranged on two sides of the shore-based belt conveyor in a supporting mode.

Through adopting above-mentioned technical scheme, during actual discharge, when the sand and stone material falls down from the feed opening of hopper directly, often can produce a large amount of dust, in addition the influence of the wind of pier, can make the dust drift everywhere, influences the discharge environment. Through setting up the baffle, on the one hand can guide the sand and stone material to fall to shore base belt feeder better, on the other hand also can reduce the dust and scatter around.

Preferably, the bottom of the frame body is provided with rollers.

Through adopting above-mentioned technical scheme, set up the gyro wheel after, the hopper can be more high-efficient according to the position adjustment self position of bow belt feeder to conveniently retrieve to the warehouse.

Preferably, the shore-based belt conveyor comprises a mounting frame arranged on the approach bridge, a driving roller, a driven roller, a belt sleeved on the driving roller and the driven roller, and a motor for driving the driving roller to rotate, wherein the driving roller and the driven roller are rotatably arranged on the mounting frame.

Through adopting above-mentioned technical scheme, can realize the transportation of sand and stone material with more simple and efficient mode, the while also is convenient for relevant personnel to install and dismantle bank base belt feeder.

Preferably, the two opposite side walls of the mounting frame are rotatably provided with a plurality of conveying rollers, one end of each conveying roller is rotatably arranged on the mounting frame, the other end of each conveying roller extends obliquely downwards to be arranged between the upper belt and the lower belt of the belt, and the conveying rollers are symmetrically arranged on the mounting frame.

Through adopting above-mentioned technical scheme, when the grit material falls on the belt, can push down the belt, the belt receives pressure and takes place to cave in, and the bottom just can be with the conveying roller contact. The transport rollers start to rotate under the friction force exerted by the belt, and the power-assisted belt is conveyed forward more stably, so that sand and stone materials are conveyed to a land destination more stably. On the other hand, the transport roller is arranged between the upper belt and the lower belt of the belt and obliquely downwards, so that corresponding space is reserved for deformation of the belt, sand and stone materials can be concentrated to the concave part more, and the sand and stone materials are not easy to fall off.

In summary, the present application includes at least one of the following beneficial technical effects:
