Description

Technical Field

[0001] The invention belongs to the field of machinery, and in particular relates to a pallet roller belt anti-heavy impact conveying device. Background Art

[0002] When transporting mining materials, in order to increase the anti-smashing ability of belt conveyors, armor pieces are often covered on the upper part of belts and rubber chain belts or armor belts are used to transport materials. Armor pieces are used to receive and transport materials. The height of coal, iron ore and other mineral silos is generally 25 meters to 35 meters. The ore flows from the upper silo to the lower silo, generating a huge impact force, which often breaks the belts, rubber chain belts and armor belts, causing repeated shutdowns. In order to solve this problem, multiple rollers are set at the bottom of the belts, rubber chain belts and armor belts. Because the rollers are supported by bearings, all gravity and impact forces act on the rollers and roller bearings. In order to make the rollers and roller bearings resistant to heavy smashing and impact, the diameters of the rollers and roller bearings are enlarged, which leads to the formation of larger grooves on the two relative arc surfaces between the rollers. The width of the groove is generally more than 3 times that of the armor piece. When the material hits the groove, the rollers are placed on the lower part of the belts, rubber chain belts and armor belts. When the belt, rubber chain belt or armor belt is placed on the conveyor belt, the belt or rubber chain belt will be smashed or pierced, and the armor belt or armor parts will be deformed or broken. In order to avoid the defects of the roller groove, an anti-smashing support plate is provided at the lower part of the belt, rubber chain belt or armor belt. Due to the large diameter of the mineral material silo, the width of the mining belt, rubber chain belt and armor belt is generally 1 to 3 meters, which leads to the large volume and area of ​​the anti-smashing support plate arranged opposite the silo. When the belt, rubber chain belt or armor belt carrying materials with a width of 1 to 3 meters and a height of 1 to 4 meters passes through the anti-smashing support plate, the belt, rubber chain belt and armor belt, which bear the weight of several tons of materials and the strong impact force, generate huge large-area sliding friction with the lower anti-smashing support plate, resulting in the bottom of the belt, rubber chain belt and armor belt being worn out quickly. In order to solve the above problems, the present invention proposes a support plate roller support belt anti-heavy-smashing conveying device. Summary of the invention

[0003] The present invention is implemented by adopting the following technical scheme: a support plate roller support belt anti-heavy impact conveying device comprises a supporting roller support plate, an anti-smashing support belt roller, a conveying frame and a conveyor belt, a plurality of anti-smashing support belt rollers are densely arranged on the supporting roller support plate, the supporting roller support plate supports the anti-smashing support belt roller to roll and rotate, the gap between the anti-smashing support belt roller and the supporting roller support plate ensures the rotation of the anti-smashing support belt roller, and when a heavy object hits the anti-smashing support belt roller, the support pad anti-smashing support belt roller does not deform, and the densely arranged anti-smashing support belt rollers are arranged on the supporting roller support plate. The supporting belt roller and the supporting roller pallet form a pallet roller anti-smashing device, the conveyor frame supports the conveyor belt, the pallet roller anti-smashing device is arranged between the upper belt and the lower belt of the conveyor belt, the conveyor frame supports the pallet roller anti-smashing device, the lower belt surface of the upper belt of the conveyor belt is supported by the anti-smashing supporting belt roller, and the conveyor belt rolls and rubs with the anti-smashing supporting belt roller when rotating to feed materials. When a heavy object hits the conveyor belt, the supporting roller pallet supports the anti-smashing supporting belt roller so that it does not deform, and the anti-smashing supporting belt roller supports the conveyor belt so that it does not deform laterally and is not damaged.

[0004] The supporting roller support plate includes an anti-smashing support belt roller bearing. Bearing support seats parallel to the conveyor belt are arranged at both ends of the supporting roller support plate. The bearing support seats support the anti-smashing support belt roller bearings. The anti-smashing support belt roller bearings support the anti-smashing support belt roller to roll and rotate. The bearing support seats include round hole bearing support seats, semicircular groove bearing support seats or square groove bearing support seats. The anti-smashing support belt roller is directly arranged in the round hole of the round hole bearing support seat, or an anti-smashing support belt roller bearing is arranged in the round hole of the round hole bearing support seat, and the anti-smashing support belt roller is arranged on the anti-smashing support belt roller bearing. The semicircular groove bearing support seat includes a full-body semicircular support shaft groove seat or a semicircular support shaft groove seat at the end of the support plate. The anti-smashing support belt roller is directly arranged on the semicircular groove bearing support seat or is connected with the semicircular groove bearing support seat through the anti-smashing support belt roller bearing.

[0005] The characteristic is that the conveyor belt includes a belt, a rubber chain belt, an armored rubber chain belt, an armored belt or a chain plate conveyor belt, the armored rubber chain belt, the armored belt or the chain plate conveyor belt includes a material conveying armor plate, the rubber chain belt includes a colloid, a cross bar, a chain roller and a chain connecting plate, the colloid wraps the cross bar, the cross bar exposed from the colloid part passes through the chain roller and the chain connecting plate, the anti-smashing support belt roller and the anti-smashing support belt roller are densely arranged, the distance between the anti-smashing support belt roller and the anti-smashing support belt roller is smaller than the distance between the cross bar and the cross bar, the distance between the anti-smashing support belt roller and the anti-smashing support belt roller is smaller than the width of the material conveying armor plate, when the material is heavily hit, it is ensured that each material conveying armor plate is supported by the anti-smashing support belt roller without deformation or cracking.

[0006] The full-body semicircular support shaft groove seat includes a semicircular groove for supporting the support belt roller, and the anti-smashing support belt roller is placed in the semicircular groove for supporting the support belt roller. The gap between the anti-smashing support belt roller ensures the rotation of the anti-smashing support belt roller and reduces the gap distance to the minimum. The distance between the axis centers of the two anti-smashing support belt rollers is smaller than the distance between the cross bars and / or smaller than the width of the material conveying plate.

[0007] The pallet roller belt anti-smashing conveying device includes a material receiving section and a material conveying section. The pallet roller anti-smashing device is placed in the material receiving section to bear the heavy impact of materials. The anti-smashing belt roller includes an anti-smashing belt roller. The anti-smashing belt roller is supported by an anti-smashing belt roller bearing or is directly used as an anti-smashing belt roller. When the conveyor belt passes through the anti-smashing belt roller, the conveyor belt drives the anti-smashing belt roller to rotate, and the conveyor belt and the anti-smashing belt roller do not wear each other.

[0008] The bearing support seat is set to be integrated or split. When an integrated bearing support seat is used, the overall anti-smashing strength of the support plate roller anti-smashing device is high. When a split bearing support seat is used, the split bearing support seat is connected to the bearing support seat by bolts, keys, pins, etc., and the replacement of the anti-smashing support belt roller is quick and convenient.

[0009] The beneficial effects of the present invention are:

[0010] 1. Multiple anti-smashing belt rollers are densely arranged on the supporting roller pallet, which supports the anti-smashing belt roller to roll and rotate. The gap between the anti-smashing belt roller and the supporting roller pallet ensures the rotation of the anti-smashing belt roller, and when a heavy object hits the anti-smashing belt roller, the supporting pad anti-smashing belt roller does not deform. The densely arranged anti-smashing belt rollers and the supporting roller pallet form a pallet roller anti-smashing device, and the conveyor frame supports the conveyor belt. The pallet roller anti-smashing device is arranged between the upper belt and the lower belt of the conveyor belt. The conveyor frame supports the pallet roller anti-smashing device, and the lower belt surface of the upper belt of the conveyor belt is supported by the anti-smashing belt roller. When the conveyor belt rotates to feed materials, it rolls and rubs against the anti-smashing belt roller. When a heavy object hits the conveyor belt, the supporting roller pallet supports the anti-smashing belt roller so that it does not deform, and the anti-smashing belt roller supports the conveyor belt so that it does not deform or be damaged. The present invention solves the defect of forming large grooves on the two relative arc surfaces between the rollers, and shortens the undesirable space in which the gap groove on the arc surface of the old roller is more than 3 times that of the armor piece to a harmless space less than the width of a single armor piece. When the material hits the support plate roller anti-smashing device, it ensures that each armor piece is supported by the lower anti-smashing support belt roller, and the anti-smashing support belt roller supports the belt, rubber chain belt and armor piece, ensuring that the belt, rubber chain belt and armor piece will not be deformed or damaged by smashing, and ensuring that the armor piece will not be deformed or broken by smashing when supported over a long distance and over a large area. The present invention arranges the anti-smashing support belt roller that rolls and rubs with the upper belt surface on the upper part of the supporting roller support plate, and makes the anti-smashing support belt roller array with a single small diameter and multiple densely arranged and large arranged area anti-smashing support belt rollers, so that the upper part of the anti-smashing support plate generates a structure of rolling friction with the belt, rubber chain belt and armor belt, thereby avoiding the defect that the anti-smashing support plate directly slides and wears against the belt, rubber chain belt and armor belt, and avoids the mine The material silo has a large silo opening and the impact force of falling materials is large, which causes damage to mining belts, rubber chain belts and armor belts. When a belt, rubber chain belt or armor belt carrying materials with a width of 1 to 3 meters and a height of 1 to 4 meters passes through the anti-smashing support roller, the belt, rubber chain belt and armor belt that bear the weight of several tons of materials and the strong impact force drive the anti-smashing support roller to rotate, ensuring that the belt, rubber chain belt and armor belt are not worn. When the gravity of the material falling from a high place impacts the belt, rubber chain belt, armor belt and armor parts, the densely arranged anti-smashing support rollers are not deformed or damaged by the large-area support pads of the supporting roller support plates. The present invention sets a huge number of increased rolling friction support points on the supporting roller support plates, and uses the principle of quantitative change to qualitative change of rolling friction fulcrums combined with the strong anti-smashing supporting force of the supporting roller support plates, which well solves the defect that the belt conveyor has a short service life due to frequent damage caused by heavy impact under the silo opening, and greatly improves the safety performance and service life of the belt, rubber chain belt and armor belt.

[0011] 2. The cross-bar is wrapped with colloid, and the part of the cross-bar exposed by colloid passes through the chain roller and chain connecting plate. The anti-smashing support belt rollers are densely arranged, and the distance between the anti-smashing support belt rollers is smaller than the distance between the cross-bars, and the distance between the anti-smashing support belt rollers is smaller than the width of the material conveying plate. When the material is heavily hit, it is ensured that each material conveying plate is supported by the anti-smashing support belt roller without deformation or cracking.

[0012] 3. Bearing support seats parallel to the conveyor belt are arranged at both ends of the supporting roller support plate, the bearing support seats support the anti-smashing support belt roller bearings, the anti-smashing support belt roller bearings support the anti-smashing support belt roller to roll and rotate, the bearing support seats include round hole bearing support seats, semicircular groove bearing support seats or square groove bearing support seats, the anti-smashing support belt roller is directly arranged in the round hole of the round hole bearing support seat, or the anti-smashing support belt roller bearing is arranged in the round hole of the round hole bearing support seat, the anti-smashing support belt roller is arranged on the anti-smashing support belt roller bearing, the semicircular groove bearing support seat includes a full-body semicircular support shaft groove seat or a semicircular support shaft groove seat at the end of the support plate, and the anti-smashing support belt roller is directly arranged in the semicircular The groove bearing support seat is connected to the semicircular groove bearing support seat through the anti-smashing support belt roller bearing. When a large piece of material hits the anti-smashing support belt roller from a high place, the anti-smashing support belt roller transmits the impact force of the large piece of material to the supporting roller pallet, and the supporting roller pallet absorbs the impact force. Therefore, the anti-smashing support belt roller and the anti-smashing support belt roller bearing will not be damaged. Therefore, a bearing with a small diameter can be selected to make the anti-smashing support belt roller rotate flexibly to ensure the rolling friction between the roller and the upper belt, rubber chain belt and armor belt. When the anti-smashing support belt roller is directly set on the bearing support seat, the anti-smashing support belt roller is used as a bearing roller, which has a simple structure, few wearing parts, and is easy to repair and replace.

[0013] 4. The support plate roller anti-smashing device is placed in the material receiving section to bear the heavy smash of materials. The anti-smashing support belt roller is supported by the anti-smashing support belt roller bearing or is directly used as an anti-smashing support belt roller. When the conveyor belt passes through the anti-smashing support belt roller, the conveyor belt drives the anti-smashing support belt roller to rotate. The conveyor belt and the anti-smashing support belt roller do not wear each other and are directly used as anti-smashing support belt rollers, eliminating the complex structure of installing the anti-smashing support belt roller bearings, saving material costs and production costs. It has a simple structure, strong anti-smashing ability and a long service life.

[0014] 5. When using an integrated bearing support seat, the support plate roller anti-smashing device has a high overall anti-smashing strength. When using a split bearing support seat, the split bearing support seat is connected to the bearing support seat by bolts, keys, pins, etc., and the replacement of the anti-smashing support belt roller is quick and convenient.
