Description

Portal three-scraper reclaimer for strip yard

technical field

The utility model relates to a portal type three-scraper reclaimer for strip-shaped material yards, which relates to bulk material transfer equipment, specifically bulk material transfer equipment for large material yards such as ports and mines that require large reclaiming capacity.

Background technique

With the continuous improvement of national environmental protection policies, bucket wheel machines, power shovels, grab loading and unloading bridges, etc. commonly used in ports have too much dust in the process of retrieving materials and cannot meet environmental protection requirements. At present, the conventional gantry scraper reclaimer for strip yards is a set of scraper chains. Due to structural limitations, when the gauge is greater than 50m, the head-up type or the main and auxiliary scraper type is used. No matter which of the above models is used, the material is taken out by a set of main scraper chains. Taking coal as an example, its reclaiming capacity does not exceed 2500t/h. This capacity is generally used in electric power, coal, cement, and coking industries, but it cannot meet the reclaiming capacity of more than 5000t/h in ports and mines.

In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel portal-type three-scraper reclaimer for strip stockyards, thereby overcoming the problems existing in the prior art.

Now there are various patent applications for scraper reclaimers, such as:

The patent number is: CN200810229407.6 "Large-span portal scraper reclaimer" patent, which is mainly composed of a portal frame, a scraper reclaimer system, a fixed end beam, a swing end beam and a luffing mechanism. The door frame is herringbone, and there is an auxiliary scraper conveying system in the herringbone door frame. The head of the system is hinged with the head of the main scraper conveying system, and the tail of the system is hinged with the connecting rod. The other end of the connecting rod is connected with the roller, and the roller walks in the guide groove fixed on the door frame.

The patent number is: CN201410536643.8 "A Half-Portal Scraper Reclaimer" patent, which mainly consists of a half-gantry, scraper conveying system, running system, unloading system, pitching mechanism, walking platform railings, electric control system, Driver's cab, etc. It is characterized in that it also includes a synchronous detection and material reclaiming automatic control system.

The patent is: No. CN201310569171.1 "A Portal Scraper Reclaimer" patent, which mainly consists of a gantry frame, a steel cable winch and an operating table. The first step and the second step are provided with a first chain scraper conveying device and a second chain scraper conveying device under the gantry frame. The first chain scraper conveying device is connected to the second chain scraper conveying device through a connecting piece, which reduces performance requirements for the chain.

The patent number is: CN201020264598.2 "Portal Scraper Reclaimer with Main and Auxiliary Scraper Drop Linkage Device" patent, which mainly includes the gantry that is located on the track and connected with the walking power mechanism. One side of the gantry is installed The installation platform is connected with the discharge end of the main scraper reclaimer through the pin shaft, and the main scraper reclaimer is connected with the winch mechanism installed on the door frame. When working, the sub-scraper reclaimer performs the reclaiming operation in areas that the main scraper reclaimer cannot reach, and the materials sent out from the discharge end of the sub-scraper reclaimer directly fall into the reclaimer of the main scraper reclaimer.

The above several patents are different from our designed structure. The portal-type three-scraper reclaimer we developed doubles the reclaiming capacity by adding a set of main scraper reclaiming system, and also transports the materials that cannot be picked up by the main scraper to the main scraper through the auxiliary scraper on the other side The board achieves a large span.

Contents of the invention

In view of the problems existing in the above-mentioned prior art, the purpose of this utility model is to research and design a kind of portal type three scraper reclaimer that a kind of novel bar stockyard is used. It is used to solve the problems existing in the prior art: 1. Insufficient retrieving capacity; 2. Limited by the small gauge of retrieving materials; 3. Cannot achieve environmental protection transfer and other problems.

Therefore, we have developed a scraper reclaimer consisting of three sets of scrapers. Two sets of main scraper systems double the original reclaiming capacity, and a set of auxiliary scrapers doubles the material that the main scraper cannot reach. Materials are supplied. Thus, a large-gauge, high-capacity scraper reclaimer is realized.

The technical solution of the present utility model is realized in this way:

The portal-type three-scraper reclaimer used in the strip stockyard described in the utility model includes a fixed end beam, a swing end beam and a door frame, and the lower parts of both ends of the door frame are respectively equipped with a fixed end beam and a swing end beam; its features One end of the mast is equipped with a main scraper chain device, and the other end is equipped with a secondary scraper chain device;

The main scraper chain device described in the utility model includes the main scraper chain A, the main scraper chain B, the wire rope hoisting mechanism A and the wire rope hoisting mechanism B; the main scraper chain A and the main scraper chain B are respectively hinged on the door The two sides of the lower part of one end of the frame; the wire rope hoisting mechanism A and the wire rope hoisting mechanism B are installed on the upper part of the mast; the wire rope hoisting mechanism A is connected with the front part of the main scraper chain A to drive the main scraper chain A to lift and fall; the wire rope The hoisting mechanism B is connected to the front of the main scraper chain B, driving the main scraper chain B to lift and fall;

The auxiliary scraper chain device described in the utility model includes the auxiliary scraper chain and the wire rope captive mechanism C; the auxiliary scraper chain is hinged at the lower part of one end of the door frame, opposite to the main scraper chain A and the main scraper chain B; the wire rope The hoisting mechanism C is connected with the front part of the auxiliary scraper chain to drive the auxiliary scraper chain to lift and fall.

The main scraper chain A and the main scraper chain B described in the utility model are arranged oppositely to the auxiliary scraper chains, but do not overlap.

The operating mechanism of the fixed end beam and the swing end beam described in the utility model has a three-in-one drive, and the synchronous operation of the motors has been considered in the design.

The portal frame of the reclaimer described in the utility model is a rigid box beam structure; due to the limited elasticity of the rigid beam of the portal frame, no complicated synchronization device is needed. When any running mechanism in the relative position leads or lags behind, the reset force of the gantry beam will force them to run synchronously. Anti-drift control as a supplementary safety mechanism.

The design of the utility model is relatively simple, and its span can cross the total width of the stockpile, and runs on two tracks on the ground outside the stockpile. The material is transferred out by a belt conveyor. The operation of the utility model is fully automatic. When starting to work, the reclaimer runs to the designated working area, the main scraper chain A and the main scraper chain B run at the same time and start to drop rapidly, when the material level gauge detects the material, the main scraper chain B stops falling, the main scraper chain Plate chain A cuts into the material pile at a slow speed and reaches the set demand. At this time, the main scraper chain A stops descending and the running mechanism starts and starts to walk and pick up materials along the set direction; the central control room receives the travel distance recorded by the travel encoder When the starting distance set by the main scraper chain B is reached, the main scraper chain B starts to descend slowly and cuts into the material pile to reach the set demand to start reclaiming. Every time the reclaimer runs in reverse, the control of the main scraper chain A and the main scraper chain B is reversed, that is, the main scraper chain B runs first and then the main scraper chain A. The auxiliary scraper chain will only start working when the end of the main scraper chain is lowered below the position of the auxiliary scraper. The work of the auxiliary scraper chain and the main scraper chain is adjusted by correcting the thickness of the material layer to be taken, and the result ensures that the output of the reclaimer is constant at all working positions. The change of reclaiming efficiency can only be realized by changing the running speed.

The advantages of the utility model are obvious, mainly manifested in:

1. The utility model can realize fully automatic control;

2. The main scraper chain design of the utility model doubles the capacity of the conventional scraper reclaimer;

3. The utility model has constant material retrieving efficiency;
