[0002] When stacking goods at the port yard, belt conveyors are usually used to transport the goods. The belt conveyors use an inclined structure to transport the goods to a high position. However, if the goods are irregular in shape and have an unstable center of gravity, coupled with the vibration of the belt conveyor during transportation, the goods transportation will be unstable and easy to lose balance on the belt conveyor, with the risk of tipping over and rolling. The tipped and rolled goods need to be collected and reloaded, which increases the extra workload and reduces the overall production efficiency. Summary of the invention

[0003] In order to overcome the shortcomings that if the cargo is irregularly shaped and has an unstable center of gravity, and the belt conveyor vibrates during transportation, the cargo transportation will be unstable, and it is easy to lose balance on the belt conveyor, with the risk of overturning and rolling, the present invention provides an anti-rollover port cargo belt conveyor.

[0009] As a preferred technical solution of the present invention, it also includes convex rods; a plurality of convex rods are fixedly connected to the upper side of each pressing plate at equal distances.

[0010] As a preferred technical solution of the present invention, the portion of the protruding rod close to the arc of the pressure plate is arranged to be inclined.

[0011] As a preferred technical solution of the present invention, it also includes a mounting plate 1 and an arc-shaped spring telescopic rod; a plurality of mounting plates 1 are fixedly connected at equal distances between the two baffles; each mounting plate 1 is located above a pressure plate; and a plurality of arc-shaped spring telescopic rods are fixedly connected at equal distances on each mounting plate 1.

[0012] As a preferred technical solution of the present invention, the end of the telescopic end of the arc-shaped spring telescopic rod is configured to be spherical.

[0013] As a preferred technical solution of the present invention, it also includes cylinder three, mounting plate two and plug plate; a number of cylinders three are fixedly connected to the upper sides of the two baffles respectively; the telescopic ends of all cylinders three on the same baffle are commonly fixedly connected to a mounting plate two; a number of plug plates are fixedly connected to the two mounting plates two at equal distances; each plug plate is located above a pressure plate respectively.

[0014] Compared with the prior art, the present invention has the following advantages: 1. Before transporting goods, the present invention places the pressure plate on the moving path at the upper end of the goods. When transporting goods, that is, when the goods are climbing a slope, the goods will force the pressure plate to rotate counterclockwise around the transmission shaft as viewed from the front to the back. The torsion spring between the pressure plate and the transmission shaft twists and stores force, so that the pressure plate contacts the upper side of the goods. Under the action of the torsion spring, the pressure plate applies downward pressure to the goods, so that the goods are tightly attached to the transport belt of the belt conveyor. Several pressure plates are arranged on the belt conveyor. When the goods are climbing a slope, they will be subjected to pressure applied by multiple pressure plates at the same time. The multiple pressure plates and the pallets on the transport belt ensure stable transportation of the goods, and prevent the goods from tipping over and rolling when moving on the inclined surface of the transport belt.

[0015] 2. When the belt conveyor transports bulk materials in batches downward, when the pallet on the conveying belt contacts the pressure plate, the pressure plate will be forced to rotate clockwise around the drive shaft as viewed from the front to the back, causing the torsion spring between the pressure plate and the drive shaft to twist and accumulate force. When the pallet on the conveying belt is separated from the pressure plate, under the action of the torsion spring between the pressure plate and the drive shaft, the pressure plate rotates counterclockwise to reset and hit the bulk material between the two adjacent pallets, thereby loosening the bulk material and facilitating subsequent packaging or sorting operations.

[0016] 3. When transporting bulk materials upward and the bulk materials roll down, the rolling materials can be caught by the pressing plate to prevent the rolling bulk materials from continuing to roll down, causing an avalanche effect and causing a large area of ​​bulk materials to roll down, thereby avoiding dust flying, polluting the surrounding environment, and increasing the cleaning workload.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0025] Example 1

[0026] A port cargo belt conveyor with an anti-rollover function, such as Figure 1-Figure 5 As shown, a belt conveyor 1 is included;

[0027] It also includes a baffle 2, a transmission shaft 3, a pressure plate 4 and a cylinder 5; a baffle 2 is connected to the front and rear of the belt conveyor 1 respectively, and the transport belt of the belt conveyor 1 is located between the two baffles 2; a number of transmission shafts 3 are equidistantly connected between the two baffles 2; each transmission shaft 3 is rotatably connected to a pressure plate 4 through a torsion spring; two cylinders 5 are fixedly connected to the front and rear of the belt conveyor 1 respectively; all cylinders 5 are fixedly connected to the corresponding baffles 2; and the two baffles 2 are slidably connected to the belt conveyor 1.

[0028] In order to support the materials and prevent the goods from rolling over, a plurality of pallets are fixedly connected to the conveying belt of the belt conveyor 1 at equal intervals.

[0029] In order to increase the friction with the goods, the surface of the transport belt of the belt conveyor 1 is set to be rough.

[0030] In order to prevent damage to the goods, the end of the pressing plate 4 is arranged to be arc-shaped.

[0031] It also includes a gear 21, a cylinder 22 and a rack 23; all the transmission shafts 3 are rotatably connected to the two baffles 2; a gear 21 is fixedly connected to the front of each transmission shaft 3; two cylinders 22 are fixedly connected to the front baffle 2; the telescopic ends of all cylinders 22 are commonly fixedly connected to a rack 23; each gear 21 is meshed with the rack 23.

[0032] When in use, the belt conveyor 1 is moved to the designated position. When it is necessary to transport goods in batches upward (for example, when transporting goods from a warehouse to a cargo ship), the belt conveyor 1 is started, and the belt conveyor 1 transports the goods upward; a number of pallets are equidistantly fixed on the transport belt of the belt conveyor 1, and the goods move on the inclined surface of the transport belt, that is, when moving on the inclined structure, the bottom of the goods is supported and restricted by the pallets, which plays a role in preventing the goods from tipping over and rolling down; but the pallets can only support the lower side of the goods, and the supporting and restricting effects on the goods are limited. If the goods are irregular in shape and the center of gravity is unstable, coupled with the vibration of the belt conveyor 1 during the transportation process, it will still cause unstable transportation of goods, and it is easy to lose balance on the climbing conveyor, and there is a risk of tipping over and rolling down; therefore, before transporting the goods, the control cylinder 1 5 drives the baffle 2, the transmission shaft 3 and the pressure plate 4 to approach the transport belt of the belt conveyor 1, so that the pressure plate 4 is located on the moving path of the upper end of the goods, and when transporting the goods, that is, when the goods are climbing When the goods are on a slope, as viewed from the front to the back, the goods will force the pressure plate 4 to rotate counterclockwise around the transmission shaft 3. The torsion spring between the pressure plate 4 and the transmission shaft 3 twists and stores force, so that the pressure plate 4 contacts the upper side of the goods. Under the action of the torsion spring, the pressure plate 4 applies downward pressure to the goods, so that the goods are tightly attached to the transport belt of the belt conveyor 1. The belt conveyor 1 is provided with several pressure plates 4. When the goods are climbing a slope, the pressure applied by multiple pressure plates 4 is simultaneously applied by multiple pressure plates 4. The stable transportation of the goods is ensured by multiple pressure plates 4 and the pallets on the transport belt, and the problem of sideways rolling and falling of the goods when the transport belt moves on the inclined surface is prevented. After the goods are transported through the pressure plate 4, the pressure plate 4 is rotated and reset under the action of the torsion spring between it and the transmission shaft 3, and is ready to assist the transportation of the next goods. The baffle 2, the transmission shaft 3 and the pressure plate 4 are driven by the cylinder 15 to approach the transport belt of the belt conveyor 1, so that the pressure plate 4 can limit goods of different sizes, which is conducive to improving adaptability and practicality.

[0033] When it is necessary to transport goods in batches downward (for example, when transporting goods from a cargo ship to a warehouse), the control cylinder 22 drives the rack 23 to move, the rack 23 moves to drive the gear 21 to rotate, and the gear 21 drives the transmission shaft 3 and the pressure plate 4 to rotate, so that the pressure plate 4 rotates to Figure 5The state shown is shown, and then the air cylinder 1 5 is controlled to drive the baffle plate 2, the transmission shaft 3 and the pressure plate 4 to approach the transport belt of the belt conveyor 1, so that the pressure plate 4 is located on the moving path of the upper end of the goods, and then the belt conveyor 1 is started, and the belt conveyor 1 transports the goods downward; when the goods move downward, based on the view from the front to the back, the pressure plate 4 is forced to rotate clockwise around the transmission shaft 3, and the torsion spring between the pressure plate 4 and the transmission shaft 3 is twisted and stored, so that the pressure plate 4 contacts the upper side of the goods. Under the action of the torsion spring, the pressure plate 4 applies downward pressure to the goods, so that the goods are tightly attached to the transport belt of the belt conveyor 1, preventing the goods from being stuck. When goods move downward on the inclined surface of the transport belt, they roll over and fall. It should be noted that compared with goods going uphill, that is, goods moving diagonally upward, goods are more likely to roll over and fall when going downhill. The specific reason is that when goods go downhill, the gravity component of the goods is downward along the inclined surface, which will aggravate the forward sliding trend of the goods. Compared with the need to overcome gravity when going uphill, gravity becomes a factor that accelerates the goods when going downhill. When goods move on the belt, going downhill may cause the center of gravity of the goods to shift forward, reducing stability. If the goods are improperly placed or have an irregular shape, this change in center of gravity is more likely to cause rollover, etc.

[0034] Example 2

[0035] On the basis of Example 1, Figure 3-Figure 5 As shown, it also includes protruding rods 31; a plurality of protruding rods 31 are welded equidistantly on the upper side of each pressing plate 4.

[0036] In order to facilitate the goods to push the pressing plate 4 when the goods are transported downward, the portion of the protruding rod 31 close to the arc of the pressing plate 4 is arranged to be inclined.

[0037] It also includes a mounting plate 32 and an arc spring telescopic rod 33; a plurality of mounting plates 32 are welded equidistantly between the two baffles 2; each mounting plate 32 is located above a pressure plate 4; and three arc spring telescopic rods 33 are welded equidistantly on each mounting plate 32.

[0038] In order to prevent the arc spring telescopic rod 33 and the pressure plate 4 from being scratched and damaged, thereby reducing the service life, the end of the telescopic end of the arc spring telescopic rod 33 is set to be spherical.

[0039] When the belt conveyor 1 transports bulk materials downward in batches, such as iron ore powder or granular materials, the cylinder 22 is first controlled to drive the rack 23 to move, the rack 23 moves to drive the gear 21 to rotate, and the gear 21 drives the transmission shaft 3 and the pressure plate 4 to rotate, so that the pressure plate 4 is in a downward tilted state, such as Figure 5As shown, the cylinder 1 5 is then controlled to drive the baffle plate 2 and its connected parts to move downward, so that the pressure plate 4 is close to the conveying belt of the belt conveyor 1, and then the bulk materials are transported downward. During transportation, the bulk materials are received by the pallet on the conveying belt. When the bulk materials are transported to the inclined part of the belt conveyor 1, the bulk materials will roll toward the pallet due to their own gravity. Finally, the bulk materials between the two adjacent pallets are in a cone shape. When the pallet on the conveying belt contacts the pressure plate 4, the pallet will force the pressure plate 4 to rotate clockwise around the transmission shaft 3, so that the pressure plate 4 and the transmission shaft 3 are in contact with each other. The torsion spring between the shafts 3 twists and stores force. When the pallet on the conveyor belt is separated from the pressure plate 4, under the action of the torsion spring between the pressure plate 4 and the transmission shaft 3, the pressure plate 4 rotates counterclockwise to reset and slap the bulk material between two adjacent pallets, thereby loosening the bulk material and facilitating subsequent packaging or sorting operations. A number of convex rods 31 are welded on each pressure plate 4 at equal intervals. When the pressure plate 4 slaps the bulk material between two adjacent pallets, the convex rods 31 are driven to move and slap the bulk material between two adjacent pallets. The bulk material is slapped by the convex rods 31, which makes it easier to slap the bulk material into looseness.

[0040] In order to enhance the force of the pressure plate 4 hitting the bulk materials so as to make the bulk materials looser, an arc spring telescopic rod 33 is arranged on the left side of the pressure plate 4. When the support plate on the conveying belt contacts the pressure plate 4, when the support plate forces the pressure plate 4 to rotate clockwise around the transmission shaft 3 as viewed from the front to the back, the pressure plate 4 will also compress the arc spring telescopic rod 33, so that the arc spring telescopic rod 33 accumulates force. In this way, when the support plate on the conveying belt is separated from the pressure plate 4, under the joint action of the torsion spring between the pressure plate 4 and the transmission shaft 3 and the arc spring telescopic rod 33, the force of the pressure plate 4 hitting the bulk materials is enhanced so as to make the bulk materials looser.

[0041] When the belt conveyor 1 transports bulk materials downward in batches, such as complete bulk materials such as iron ore, the control cylinder 1 5 drives the baffle 2 and its connected parts to move upward to prevent the baffle 2 and its connected parts from blocking the ore transportation.

[0042] Example 3

[0043] On the basis of Example 2, Figure 3 and Figure 6 As shown, it also includes a cylinder three 41, a mounting plate two 42 and an insert plate 43; two cylinder three 41 are fixedly connected to the upper sides of the two baffles 2 respectively; the telescopic ends of all cylinder three 41 on the same baffle 2 are commonly fixedly connected to a mounting plate two 42; a number of insert plates 43 are equidistantly welded on the two mounting plates two 42; each insert plate 43 is located above a pressure plate 4.

[0044] When the belt conveyor 1 transports bulk materials in batches upward, the materials are supported by the support plate of the conveying belt to prevent the bulk materials from rolling down. When the conveying belt is running and there are a lot of bulk materials, the bulk materials on the upper part of the belt conveyor 1 will roll down. The bulk materials rolling down from the upper part have a long travel distance, which can easily cause an avalanche effect, resulting in a large area of ​​bulk materials rolling down. The rolling bulk materials will cause dust to fly, pollute the surrounding environment, and increase the cleaning workload; therefore, first control the cylinder 1 5 to drive the baffle 2 and its connected parts to move downward, so that the pressure plate 4 is close to the support plate of the conveying belt of the belt conveyor 1, and then control the cylinder 3 41 to drive the mounting plate 2 42 and the plug plate 43 to move downward, so that the plug plate 43 contacts the side of the pressure plate 4, thereby limiting the rotation of the pressure plate 4 around the transmission shaft 3, such as Figure 6 As shown, the bulk materials are then transported upward. When the bulk materials roll down, the rolled materials can be caught by the pressing plate 4 to prevent the rolled bulk materials from continuing to roll down, causing an avalanche effect, causing a large area of ​​bulk materials to roll down, thereby avoiding dust flying, polluting the surrounding environment, and increasing the cleaning workload; after the bulk materials are transported, the control cylinder three 41 drives the mounting plate two 42 and the plug plate 43 to move upward and reset, so that the plug plate 43 is separated from the side of the pressing plate 4, and then the control cylinder two 22 drives the rack 23 to move, and the rack 23 moves to drive the gear 21 to rotate, and the gear 21 drives the transmission shaft 3 and the pressing plate 4 to rotate, and based on the view from the front to the back, the transmission shaft 3 and the pressing plate 4 rotate clockwise, so that the pressing plate 4 turns over, so that the material caught by the pressing plate 4 falls onto the conveying belt, and then is transported upward by the conveying belt.

[0045] When the belt conveyor 1 transports bulk materials upward in batches, such as Figure 6 As shown, the baffle plate 2 and its connected parts are driven to move upward or downward by controlling the air cylinder 15 to adjust the distance between the pressing plate 4 and the transport belt of the belt conveyor 1, so that the pressing plate 4 can receive the falling block materials, and the distance between the pressing plate 4 and the transport belt of the belt conveyor 1 will not affect the transportation of the block materials. The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present invention.
