Abstract

PURPOSE:To improve efficiency of utilization of a yard and realize automatic and certain movement to a bench of the next stage by finding dimensions of a tall pile of materials previously and setting a traveling interval of a machine and angles of depresion, elevation and swivel and the like of a boom. CONSTITUTION:On the basis of dimensions of a tall pile of materials found previously, an interval of movement of a bucket wheel 3 in the longitudinal direction of said pile is set at a position leaving a room of the minimum bench length (m) required for landing of the wheel 3. Also, angles of depression and elevation of a boom are set at an interval corresponding to the height of one bench to be decided depending upon the diameter of the wheel, while the angle of swivel of the boom is set at an angle after deducting from the width of said pile an angle which moves due to inertia of the boom. Then, dimensions of the whole pile are found at first, subsequently the wheel is landed on the topmost part of the pile to be driven into rotation as the boom is swiveled in the lateral direction of the pile while an inching operation of machine traveling is being conducted. A bench of the topmost layer is thus cleared out covering the predetermined length and subsequently, the wheel is landed on a bench of the next stage through combined operation of swivel, depression and elevation of the boom and also traveling of the machine.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of operating a reclaimer in a material storage yard, and in particular, a pile of raw materials is divided into a plurality of benches in the height direction and the raw materials are sequentially discharged downward. The present invention relates to a method for automatically switching to the next stage bench.

Reclifiers are used to discharge raw materials such as coal and ore that have been piled up in raw material yards. FIG. 1 is a diagram showing an example of the structure of such a liqueur 1/-mer, and FIG. 2 is an explanatory diagram showing an outline of a raw material dispensing method using this liqueur 1/-mer.

In Figure 1, a boom 2 whose angle (elevation angle) is adjusted by a crane mechanism etc. is attached to the aircraft 1 which is traveling on a 1/-
is attached and supported so that it can swing (swivel) freely.

A packet wheel 3 that can be rotated is attached to the tip of the boom 2. A plurality of packets 5 are provided on the circumference of the packet wheel 3 for discharging raw materials from a stack 4 of raw materials. A boom conveyor is installed in the boom 2, and the material discharged by the packet wheel 3 is supplied to this boom conveyor and conveyed to the machine body 1. The raw material conveyed into the machine body 1 from the boom conveyor 2 is dropped and supplied to a conveyor 6 installed on the ground or other conveyance means, and is conveyed to a desired position.

In order to unload raw materials by the stacking pile 4 or the packet wheel 3, the boom 2 of the reclaimer is rotated and raised, and the machine body 10 is moved. Transfer and supply to the process sequentially. In this case, a method is adopted in which the stack of raw materials is divided into a plurality of benches in the height direction and the raw materials are sequentially discharged downward.

FIG. 2 is an explanatory diagram illustrating such a raw material discharging method. In FIG. 2, arrow line A indicates the packet wheel 3.
The arrow line A and the inner circular arc indicate the movement trajectory of the boom 2.
The figure shows a turning trajectory due to the turning movement of the aircraft 1, and the straight line portions at both ends show the trajectory due to the running motion of the aircraft body 1.

FIG. 3 is an explanatory diagram showing a conventional method of operating a rift 1/-mer in a stock storage yard. In this conventional method, the height ζ (elevation angle) of the boom 2 is kept constant at the point at which a predetermined travel distance with the same pliers (layer) is completed. However, depending on the height of the boom 2, by repeating a certain amount of traveling inching, the lower part of the boom 2 may come into contact with the end of the next stage bench, that is, the corner X in Fig. 3. This is the driving limit at that elevation. That is, when the boom 2 comes into contact with the point X, it becomes impossible for the packet wheel 3 to discharge any more raw material. Therefore, in such a case, move aircraft 1 to the third
Move backward by the distance shown in the figure and return to the original position, then lower the elevation angle from payout 1 to hench height and lower the packet wheel 3 to the position shown by the two-dot chain line in Figure 3. to change the bench level. Next, the raw material is discharged while repeating the boom rotation and the moving movement of the machine body in the same manner as described above. In this position, the raw material is continuously discharged until the lower part of the boom 2 comes into contact with the end of the rear bench, as in the case described above.

This conventional raw material dispensing method is called the fixed span method, and the dispensing distance for each bench is usually 8 to 12
? Since the boom 2 can have a length of
Because the discharging distance is long, the foot of the pile is long during discharging or in the middle of discharging (remains), and the occupation rate of the raw material yard area is increased accordingly, so a large amount of space is required in the yard space during discharging. The disadvantage is that the utilization efficiency of the raw material yard is low.

Furthermore, the traveling distance of the reclaimer when moving forward and backward is longer due to the longer dispensing distance for each bench.
Errors in detecting the position of the machine body 1 accumulate, which tends to make the transition to the next bench inaccurate, making it difficult to dispense a fixed amount.

The purpose of the present invention is to solve the drawbacks of the conventional raw material discharging method, to improve the efficiency of yard use, and to provide a reclaimer operation in a material storage yard that can automatically and reliably transfer to the next stage bench. The purpose is to provide a method.

The characteristics of the present invention are that the length, height, and width (D f
The dimensions of R1,+ are determined, and the travel distance lI# in the longitudinal direction of the packet wheel stack is set at a position that leaves the minimum bench length required for the nuclear packet wheel to land, and the defective angle of the boom is determined by the packet wheel diameter. The boom rotation angle is set as the width of the stack minus the angle of movement due to the inertia of the boom, and based on these settings, the aircraft's travel and boom elevation are adjusted. The point is to combine each turning operation and move to the next stage bench.

That is, according to the present invention, there is provided a machine body capable of traveling, a boom supported so as to be operable to rotate and raise the machine body, a boom conveyor provided along the boom, and a boom conveyor provided at the tip of the boom. Using a reclaimer equipped with a packet wheel that rotates to take out the raw material and supply it to the boom conveyor, the pile of raw materials is divided into multiple benches in the height direction and sequentially moved downward. In the method of operating a reclaimer in a material storage yard for discharging raw materials, the dimensions of the pile, such as the length, height, and width of the pile, are determined in advance, and the moving distance of the packet wheel in the length direction of the pile is determined by The boom is set at a position that leaves the minimum bench length required for landing, the boom elevation angle is set at the distance equivalent to one bench height determined by the packet wheel diameter, and the boom rotation angle is determined by the inertia of the boom from the width of the pile. It is characterized by setting the angle by subtracting the movement angle, and based on these setting values, the movement of the aircraft and the operations of raising, raising, and turning the boom are combined and transferred to the next stage bench.
A method of operating a rift 1/-mer in a stock storage yard is provided.

The fourth page 4 is an explanatory diagram illustrating a control system of a reclaimer operating device for carrying out the method of operating a rift 1/-mer in a waste storage yard according to the present invention. The reclaimer operating device shown in FIG. 4 has a running position detector 11 that detects the running of the machine body 1, and detects the distance between the packet wheel 3 and the bench surface and the distance between the packet wheel 3 and the end of the raw material pile 111. Therefore, the ultrasonic switch 18 provided on the packet wheel, the wheel stopping distance setting device 12 for setting the movement III (stopping distance) of the packet wheel in the longitudinal direction of the product 111, and the turning angle of the boom 2 are known. The rotation position detector 13 and the vertical position of the boom 2 (
an elevation position detector 14 for determining the elevation angle), a swing angle setting device 15 for setting the maximum swing range (left and right direction) of the boom in the stacking width direction, and a swing angle setting device 15 for setting the boom 2's elevation angle in the height direction. Elevation setting device 16 for setting the angle and electric power for driving the packet wheel 3! + Machine load S: Load current detector 17 that detects the degree of contact between the raw material product 111 and the packet wheel from the flow, and the output signals of each of the above setting devices and each detector. It is equipped with a control device 2o for controlling each of the driving motors M1 to M4. Lift 1 controlled by the control bag ft20
/- As a motor for aircraft operation, electric motor M for aircraft travel is used.
1, a boom rotation electric motor M2, and an elevation electric motor M3,
Each packet wheel electric motor M4 is provided. The RIF 1 normal operation device shown in Figure 4 detects the positions and conditions of the aircraft 1 and boom 2, and automatically performs the required amount of operation and movement for the boom and the aircraft based on the detected values. Then, the method of operating a reclaimer in a garbage storage yard according to the present invention is carried out.

FIG. 5 is an explanatory diagram illustrating one embodiment of the method for operating a reclaimer in a waste storage yard according to the present invention.

When carrying out the riff 1/-mer operation method shown in Fig.
It is stored in a computer within the control device 20 in the figure. The dimensions of the entire pile can be determined in advance by operating various detectors while the stacker or recruiter rotates its boom along the pile, raises and lowers it, or runs its body. Furthermore, these can be calculated in advance based on samples such as past pile-up performance data.

In this state, the packet wheel 3 of the rift 1/-mer lands on the top of the pile of raw materials, and while rotating it, the boom 2 is turned in the width direction of the pile. When the packet wheel 3 reaches the end of the pile, the width direction dimension 17i' stored in the control device 20: Based on the width direction dimension 17i' (based on It is preferable to use an ultrasonic switch (ultrasonic switch 18 in Fig. 4) installed on the packet wheel to confirm that the packet wheel has reached the top of the mountain, and turn it over. It is possible to reliably prevent scraping or excessive turning.

The above turning operation of the boom 2 is repeated several times while being accompanied by the inching operation of the machine body 1. ko5t=te,#
The bench of the t-hi layer is laid out over a specified length, and the fifth
The raw material dispensing in the part 1-1 in the figure [7 is completed 1, After completing the dispensing in 1-1 in Fig. The packet wheel 3 is landed on the next bench. After landing, the boom is rotated several times and the machine body 1 is moved in the same way as described above to discharge the raw material in the part 2-1 in Fig. 5. The same goes for the rest. In step 1, the raw material discharging operations 2 of 3-1 and 4-1 in Figure 5 are performed, and the raw materials in the area indicated by the two-dot chain in Figure 5 are discharged from the uppermost layer to the lowest layer 1. After that, the payout of the top layer 1-2 and the portions where R<2-2, 3-2 and 4-2 are performed again.
-3.2-3. Raw materials are discharged from parts 3-3 and 4-3, and then returned to the top layer again, and from 1-4 to 2-4.3-4 and 4-4. Raw materials are sequentially dispensed from each bench. In Fig. 5, the movement percentage (I distance) of the packet wheel 3 in the longitudinal direction of the pile for each bench can be expressed as !1, and during this movement distance, as described above (while keeping the elevation angle of the boom 2 constant), The boom 2
The turning operation is repeated multiple times.

Note that in response to each turning operation of the boom 2, the traveling inching operation of the body 1 is also repeated the same number of times.

In this case, the product of packet wheel 3 111 longitudinal times VC
The moving distance is set at a position that leaves the minimum bench length fim for the landing of the packet wheel, and the dimension m shown in Fig. 5 and 6-1 is within the range where the upper layer material does not collapse. Ru. For example, packet wheel 3
When the diameter of 7rL is 6m, this dimension 7rL is 0.37π to 1.
Within a range of 5m ((set).

The elevation angle of Bu-mu 2 can be set at a distance equivalent to the Akanezu of 1 bench, which was set in advance at Sekiyama's Kochisho and Boo VC. The relationship V with the diameter of the packet wheel 3 is determined so as not to put a load on the wheel. In other words, if the elevation p1 + angle, that is, the height of one bench is made too thick, the V repacket wheel When the load increases to 3, the packet wheel eventually stops and becomes 1-(-15).

For this reason, normally (゛↑1 of the diameter of packet wheel 3)
/2, or smaller for materials that are prone to collapse ζ
In general, the height of the boom 2 must be set to a value equal to or less than 1/2 of the diameter of the packet wheel.
The elevation angle is set. For example, when the diameter of the packet wheel is 6 m, the elevation angle is expressed as a distance equivalent to one bench for ease of control, and is set to 3 m at that stand.

The stopping position h of the packet wheel 3 in the width direction of the pile of raw materials, that is, the turning angle of the boom 2, must be set so as not to cause the load to run out at the end when turning. Movement due to inertia (set by the angle subtracted by the angle. This turning angle is a value that changes for each bench height, and the turning angle corresponding to the width for each height of each bench is set by the inertia of boom 2. The turning angle can be set by subtracting the moving angle.

For example, since the movement due to inertia (the angle is 1 to 2 degrees), each bench is set to a turning angle that is the angle in which the dimension in the pile width direction is expressed as the turning angle minus 1 to 2 degrees, When this rotation angle is reached, the direction of boom rotation is reversed.

As explained above, by the combined operation of the inching operation of the machine body 1 and the raising, raising, and turning operations of the IfC boom 2, the stack is removed to the lowest layer while sequentially switching to the succeeding bench. As explained above, in the method of operating a rift 1/-mer in a storage yard of the present invention, the dimensions of the pile, such as the length, height, and width, of the pile are determined in advance, or the dimensions of the pile are not stored in a computer. Based on the dimensions of these piles, the moving distance of the packet wheel 3 in the direction of the pile length is set at a position that leaves the minimum bench length m for the packet wheel to land on. The turning angle of boom 2 is set at a distance equivalent to one bench height determined by the wheel diameter, and the swing angle of boom 2 is set as the angle subtracted by the inertia of the boom from the width of the pile. Move to the next stage bench by performing a combined operation of 10 traveling, raising, raising, and turning the boom 2,
Since raw materials are automatically dispensed in sequence, the number of turns, elevations, and movements of the machine when the dispensing lever is closed at the same time increases compared to the conventional technology, but these operations can be automatically performed with a combined operation. Since this is done in a consistent manner, the remaining distance #I at the base of the raw material pile can be made small without reducing the dispensing efficiency.

That is, as shown in FIG. 5, the remaining distance L1 at the foot of the mountain when the present invention is applied is significantly shorter than the remaining distance ls at the foot of the mountain according to the conventional constant span method.

Therefore, by employing the riff 1 hummer operating method of the present invention, the raw material yard space can be secured by an amount corresponding to the reduced remaining distance ζ, and the usage efficiency of the raw material yard can be improved.

Also, determine the dimensions of the raw material pile in advance (or (1) store them in the computer in advance) and calculate the travel distance of the machine 1 (distance in Figures 5 and 6! □), and calculate the elevation angle of the pool 2. Since the rotation angle and turning angle, etc. are all set, the traveling distance of the aircraft 10!1 is shorter than the traveling distance of the conventional constant span method shown in Fig. 3, and this affects the position detection accuracy of the aircraft 1. It is possible to perform accurate fixed amount dispensing without
The amount of raw material discharged to the subsequent stage by the conveyor 6 in FIGS. 1 and 2 can be made constant and uniform, and the amount of raw material discharged per set value (・ζ) can be controlled to an accurate constant value. 1. As is clear from the above explanation (according to the present invention), it is possible to improve the usage efficiency of a raw material yard, and to easily perform accurate quantitative dispensing. A method of operating a yard recruiter is provided.
