Description

A reclaimer with automatic detachable buffer bed

technical field

The invention belongs to the field of bulk material conveying equipment, and relates to a reclaimer with an automatic detachable buffer bed.

Background technique

The reclaimer is a continuous and efficient bulk material mining equipment, which is widely used in material storage and conveying systems in industries such as electric power, building materials, chemicals, mines, docks, coal, metallurgical steel plants, and grain. Common reclaimers include bucket wheel (stack) reclaimer, portal/bridge type scraper reclaimer, portal/bridge type bucket wheel reclaimer, drum reclaimer, circular stockyard bucket wheel stack reclaimer machine and so on. Among them, the bridge-type scraper reclaimer, bridge-type bucket wheel reclaimer, drum reclaimer, etc. adopt the full-section reclaiming method and are equipped with a rake device, which has a good material mixing effect, so it is often used in homogenized materials. field. In order to achieve the best homogenization effect in the homogenization stockyard, the stacker usually adopts the herringbone stacking mode. The resulting problem is that the reclaimer is idle for a long time when stockpiling the stockyard , resulting in a waste of resources.

In order to avoid idle waste, equipment transfer technology is becoming more and more popular. The so-called equipment transfer technology is simply a technology or means that the same equipment can be transferred to different storage yards for operation. The transition technology is not only applied to the reclaimer, but also sometimes applied to the transition operation of the main machine of the stacker. The biggest economic benefit of the transition operation is to make full use of the equipment and greatly reduce the number of equipment.

In the equipment transfer technology, one of the most critical technologies is the automatic detachment technology of the impact bed. Because the unloading of the belt conveyor on the reclaimer will cause impact damage to the system belt conveyor, a buffer bed is usually set above the ground reclaiming belt conveyor, and the buffer bed is pressed on the lower part of the belt surface of the ground belt conveyor, so it cannot be transferred in the transition field. How to separate the impact bed from the reclaimer has become a new technical problem.

Contents of the invention

The object of the present invention is to provide a reclaimer with an automatic detachable buffer bed, so that the reclaimer can be transferred to work, avoiding idle resources and causing waste of resources, and at the same time greatly reducing the reclaiming equipment in the reclaiming field. The reclaiming yard saves costs; at the same time, the buffer bed is used to prevent the impact damage of the feeding point to the reclaiming belt conveyor on the ground. The automatic detachment buffer bed device of the reclaimer adopts a mechanized automatic detachment method, which has the advantages of simple design structure, low manufacturing cost, convenient maintenance, fast detachment, and high reliability.

The technical scheme of the present invention: a reclaimer with an automatic detachable buffer bed, including a ground reclaimer belt conveyor, a transfer trolley and a reclaimer, and a ground reclaimer belt conveyor is provided outside the material pile in the stockyard. There is a stacking belt conveyor and a stacker between the stockpile in the stockyard, a transfer trolley is provided at one end of the stockpile in the stockyard, and a buffer bed is provided on the ground reclaiming belt conveyor, and the buffer bed is connected to the reclaimer through a hook. Because of the buffer bed, it can prevent the impact and damage of the feeding point on the ground reclaiming belt conveyor; because the buffer bed and the reclaimer are connected by hooks, the reclaimer can load and unload the buffer bed for transition operations, avoiding idle resources , resulting in a waste of resources, and at the same time greatly reducing the reclaiming equipment in the reclaiming yard, saving costs for the reclaiming yard.

Principle of work of the present invention: as shown in Figure 6 and Figure 7, the horizontal section on the left side and the concave section track on the right side in Figure 6 are used for the stable shelving of the trolley type impact bed 6, and belong to the stop position. When the trolley type impact bed 6 was at the stop position, the reclaimer 4 of the transfer operation moved to the right and began to unhook, and to move to the left was to start to hook. The trolley type impact bed 6 rear side wheels 9 of the track section between the horizontal section on the left side of the impact bed rail bracket 7 and the concave section are lifted, so that the rear side hanging shaft 8 enters the locking section of the left and right limit positions above the hook 5 . At this time, the trolley-type impact bed 6 is connected with the reclaimer 4 as a whole, which prevents the detachment process from slipping or falling. Figure 7 shows the respective height positions of the front wheels and rear wheels of the buffer bed wheels 9 at the same time, and the center line shows the hooking/unhooking height positions of the hanging shaft 8, and the corresponding wheels 9 are located on the left side of the buffer bed rail bracket 7 The position of the side horizontal segment and the right concave segment rail. The dotted line above the central line represents that the hanging shaft 8 is lifted by the track and enters the limit position above the hook 5 . The dotted line below indicates that the hanging shaft 8 moves to the bottom of the hook and enters the hooking position below the hook 5, and the horizontal section of the dotted line below is the position track after the hanging shaft 8 is hooked in place. From a to b is the decoupling operation, and when it arrives at b, the reclaimer 4 continues to move forward and begins to decouple smoothly until it is all completed. From b to a is the hook operation, and after reaching point a, it means that the hook is completely in place. Can draw from the track of front and back wheel 9/hanging shaft 8 on the figure, must have hanging shaft 8 to be in the hook 5 limiting positions in the whole decoupling or hooking process. The possibility of the trolley-type impact bed 6 slipping off-line during the detachment process is completely avoided, indicating that the entire detachment working condition is very safe and reliable.

Fig. 2, Fig. 3 and Fig. 4 respectively represent the structural diagrams of the automatic detachment buffer bed 6 of the reclaimer 4 of the present invention under various working conditions.
