Description
Technical field
The present invention relates to mining machinery, relate more specifically to a kind of nation device.
Background technology
Nation device refers to the Transport Machinery used in the digging of mineral, production, transhipment, the courses of processing such as such as coal, mainly includes mining belt conveyor. Mining belt conveyor has that freight volume is big, working environment is complicated, bearing capacity is strong and the feature such as transportation range length, is all used widely in each main mining area of China. Mining belt conveyor is possible not only in mineral mining process to use, can also use equally in the mineral course of processing. In energy consumption, mining belt conveyor can effectively reduce energy consumption, increases economic efficiency, and compares the means of transportation such as automobile and more can save the energy and protection environment. It addition, mining belt conveyor is in maintenance, have that maintenance is little, safeguard the features such as simple, be therefore also affected by liking of mineral processing enterprise.
In actual use, due to reasons such as installation quality, belt tension and guide roller surface roughness, often there is the phenomenon of belt deviation in mining belt conveyor. First, belt deviation can directly result in belt both sides discontinuity, and As time goes on, this discontinuity can cause that again the service life of belt shortens. In extreme circumstances, when the side of belt crosses the edge of deflector roll (driving roller or driven voller), belt can rub with the edge of deflector roll in operation, damages thus accelerating it. Secondly, particularly with the mining belt conveyor adopting flat rubber belting, belt deviation also results in mineral and drops and the problem such as conveyer galloping.
Prior art includes the technical scheme of multiple solution belt deviation problem. These technical schemes are broadly divided into two classes, and a class is to arrange independent regulating roller to belt conveyor, when belt generation sideslip being detected, utilize the regulating roller side applying effect to belt, to force a return to middle position.Another kind of is arrange lifting apparatus to the moveable idler of belt conveyor, when belt generation sideslip being detected, just come the side (that is, belt is towards the side of its sideslip) of lifting moveable idler by lifting apparatus, thus forcing belt to return to normal operating position.
But, above-mentioned solution still has problems. Specifically, the side of belt is applied active force and rubs with belt simultaneously by regulating roller, can cause belt side edge accelerated wear test in the course of time. Additionally, for flat rubber belting conveyer, lifting apparatus can cause belt to tilt, not only can cause that mineral drop in correction operation, but also may result in correcting excessively. Furthermore, the deviation detecting device supporting with both deviation correcting devices is required for being separately provided, and this correspondingly can increase number of components and cost. Therefore, this area needs a kind of technical scheme solving nation device especially Conveyer Belt Deviating problem. Compared with above-mentioned prior art, belt will not be caused abrasion by the program, and without causing mineral to drop in correction operation and rectifying a deviation excessively, and overall structure is simpler and easy and lower in cost.
Summary of the invention
Present invention seek to address that the problems referred to above. Specifically, inventor have found that, the belt of nation device why sideslip, immediate cause is in that belt both sides unbalance stress, and belt tends to towards the less side sideslip of stress. Based on this discovery, inventors herein propose technical scheme, namely, Tension Difference according to belt both sides (reflection is exactly pressure differential to cylinder) detects tendency or the fact of belt deviation, and based on tension/pressure equilibrium principle to the less cylinder side applied thrust of belt stress to correct belt deviation. Therefore, technical scheme can detect tendency or the fact of belt deviation in the very first time, thus implementing in time to correct operation, makes the sideslip of the belt of nation device be eliminated or suppress.
More specifically, the present invention provides a kind of nation device, described nation device includes belt, cylinder and for supporting the rolling stand of described cylinder, described cylinder rotates together with described belt, and described cylinder includes the first rotation axle head and second and rotates axle head and for receiving and support the described first clutch shaft bearing rotating axle head and for receiving and supporting the described second the second bearing rotating axle head. described nation device is characterised by: described rolling stand lies in a horizontal plane on smooth matrix and can move on described smooth matrix, and described nation device also includes grading automatical deviation correcting device, described grading automatical deviation correcting device includes controller, sense described first and rotate the axle head the first pressure transducer to the pressure of described clutch shaft bearing, sense described second and rotate axle head to the second pressure transducer of the pressure of described second bearing and along making the direction of described belt tension to the first hydraulic cylinder of described rolling stand applied thrust and the second hydraulic cylinder, described controller receives the first sensing value of described first pressure transducer and the second sensing value of described second pressure transducer, calculate the difference between described first sensing value and described second sensing value and the size according to described difference comes the first hydraulic cylinder described in order or described second hydraulic cylinder to described rolling stand applied thrust, wherein said belt is provided with multiple first anti-bias element, and described cylinder is provided with multiple second anti-bias element, and described first anti-bias element is arranged to described second anti-bias element that position is corresponding and form fit is to prevent described belt deviation,And storage has first threshold, Second Threshold and the 3rd threshold value in wherein said controller, when described difference is equal to or more than described first threshold and during less than described Second Threshold, the first hydraulic cylinder described in described control order or described second hydraulic cylinder apply the first thrust to described rolling stand; When described difference is equal to or more than described Second Threshold and during less than described three threshold value, the first hydraulic cylinder described in described control order or described second hydraulic cylinder are applied more than the second thrust of the first thrust to described rolling stand; When described difference is equal to or more than described three threshold value, the first hydraulic cylinder described in described control order or described second hydraulic cylinder are applied more than the 3rd thrust of the second thrust to described rolling stand.
Skilled addressee readily understands that, under the normal operating state that sideslip does not occur, belt is applied to the first rotation axle head of cylinder and the pressure of the second rotation axle head is roughly equal. But, if there is sideslip in operation in belt, then its first rotation axle head being applied to cylinder and the second pressure rotating axle head can change, correspondingly, difference can be there is between the pressure that described first pressure transducer and the second pressure transducer sense, and sideslip degree is more big, this difference is more big. Owing to belt is invariably prone to towards the less side sideslip of stress, the pressure that therefore belt detects towards that side of its sideslip is generally less. So, when the pressure difference value of both sides reaches certain threshold value, controller just can order belt towards the hydraulic cylinder of its sideslip side to described rolling stand applied thrust, now, owing to rolling stand lies in a horizontal plane on smooth matrix and can move on smooth matrix, therefore, the thrust of this side hydraulic cylinder can make the pressure of the both sides of rolling stand again reach balance, so that belt gradually returns to normal operating position. It is to be noted about this point, in practical operation, when belt to the side sideslip of rolling stand and is positioned at the hydraulic cylinder of this side and is activated and during to rolling stand applied thrust, the hydraulic cylinder of opposite side is preferably at slight pressure release state, and belt so will not be made to bear excessive tension force.
In the preferred implementation of above-mentioned nation device, when described first sensing value is less than described second sensing value, the side applied thrust to described rolling stand of the first hydraulic cylinder described in described control order; When described first sensing value is more than described second sensing value, the opposite side applied thrust to described rolling stand of the second hydraulic cylinder described in described control order.
What skilled addressee readily understands that is, belt is invariably prone to towards the less side sideslip of stress in operation process, therefore, when the first sensing value is less than the second sensing value, show the belt side sideslip to the first hydraulic cylinder place, now need described first hydraulic cylinder side applied thrust to described rolling stand, so that belt is gradually to opposite side travelling backwards. On the contrary, when the second sensing value is less than the first sensing value, show the belt side sideslip to the second hydraulic cylinder place, now need described second hydraulic cylinder opposite side applied thrust to described rolling stand, so that belt is gradually to the side travelling backwards at the first hydraulic cylinder place.
In the preferred implementation of above-mentioned nation device, described rolling stand also includes the clutch shaft bearing seat and the second bearing block that are respectively used to hold described clutch shaft bearing and described second bearing, described first pressure transducer and described second pressure transducer and is separately positioned in described clutch shaft bearing seat and described second bearing block and between described bearing and bearing block.
What skilled artisans appreciate that is, when belt is to the side sideslip of cylinder, belt is applied to the pressure rotated on axle head of cylinder opposite side and can significantly increase, and this pressure increase can be delivered on the bearing supporting this rotation axle head and be eventually transferred on the bearing block of spring bearing. The present invention utilizes the characteristic of pressure transducer-such as voltage sensitive sensor, it is arranged between the bearing of cylinder and bearing block dexterously, therefore can not only detect the pressure change that belt deviation causes exactly, but also existing structure need not be made and significantly changing. It is pointed out that in the present embodiment about this point, described pressure transducer is necessarily placed at the side that inner side-namely close nation device is central of described bearing and bearing block.
In the preferred implementation of above-mentioned nation device, described first anti-bias element is the fin being provided integrally on the inner surface of described belt, described second anti-bias element is the groove being provided integrally on the outer surface of described cylinder, and described fin is embedded in described groove in operation. In the preferred implementation of above-mentioned nation device, described fin is along the inner surface horizontal expansion of described belt and has triangle or arc section, and described groove is along the outer surface longitudinal extension of described cylinder and has the triangle or arc section that mate with described fin.
What skilled addressee readily understands that is, it is provided with on the outer surface of multiple fin and described cylinder on the inner surface of described belt and is provided with multiple groove, and when described fin or groove have triangle or arc section, as long as described fin and described groove fit to together with, described cylinder is applied to during the counteracting force of described belt will make described belt automatically fixed, thus being prevented effectively from belt deviation. This anti-deviation mode simple in construction but effect are obvious, have good cost benefit.

Controller 17, for receiving signal from pressure transducer 18,19, controls the first hydraulic cylinder 15 and the second hydraulic cylinder 16 so that along the direction both sides applied thrust respectively to rolling stand 12 making belt 6 tensioning, thus changing the position driving cylinder 3 left and right sides. Change along with the position driving cylinder 3 left and right sides, belt 6 is applied to the support force of the both sides driving cylinder 3 and changes, this just forces belt 6 to move and be eventually returned to its normal position gradually to opposite side along with the rotation driving cylinder 3, it is achieved new dynamic balance (describing this process in detail below in reference to Fig. 4). Specifically, controller 17 receives the first sensing value from the first pressure transducer 18, receives the second sensing value from the second pressure transducer 19, calculate the difference between the first sensing value and the second sensing value, by the size of described difference compared with the threshold value being stored in advance in controller 17, if described difference less than threshold value, then continue to the first and second sensing value and calculate between them difference subsequently by the difference of up-to-date acquisition compared with threshold value. If aforementioned arbitrary difference time compared is equal to or more than threshold value, then controller 17 orders the first hydraulic cylinder 15 or the second hydraulic cylinder 16 along making the direction of belt 6 tensioning to rolling stand 12 applied thrust.
In controller 17, storage has multiple threshold value, includes but not limited to first threshold, Second Threshold and the 3rd threshold value. Preferably, when previously described difference is equal to or more than first threshold and during less than Second Threshold, controller 17 correspondingly sends the first instruction. First instruction makes the first hydraulic cylinder 15 or the second hydraulic cylinder 16 apply the first thrust to rolling stand 12. Preferably, when previously described difference is equal to or more than Second Threshold and during less than three threshold values, controller 17 correspondingly sends the second instruction. Second instruction makes the first hydraulic cylinder 15 or the second hydraulic cylinder 16 be applied more than the second thrust of the first thrust to rolling stand 12. Preferably, when previously described difference is equal to or more than three threshold values, controller 17 correspondingly sends the 3rd instruction. 3rd instruction makes the first hydraulic cylinder 15 or the second hydraulic cylinder 16 be applied more than the 3rd thrust of the second thrust to rolling stand 12. In a preferred embodiment, when the first sensing value is less than the second sensing value, first hydraulic cylinder 15 side (the being upside in figure 3) applied thrust to rolling stand 12 ordered by controller 17, so that belt 6 is mobile to opposite side (being downside in figure 3). When the first sensing value is more than the second sensing value, second hydraulic cylinder 16 opposite side (the being downside in figure 3) applied thrust to rolling stand 12 ordered by controller 17, so that belt 6 is mobile to relative side (being upside in figure 3).
