Description

Technical Field

[0001] This invention relates to the field of carriage tipping technology, and more specifically to a connecting arm for pressing a carriage beam and a carriage tipping device. Background Technology

[0002] Existing freight transport vehicles generally include open-top and cabinet-door types. In open-top vehicles, the open top facilitates loading goods into the cargo compartment using excavators, backhoes, and loaders. During unloading, a pressure beam is installed on the cargo compartment, and a tipper is connected to the pressure beam. The tipper drives the pressure beam to tilt the cargo compartment, allowing the goods to be unloaded. However, in actual operation, when the tipper drives the pressure beam to tilt the cargo compartment, there is a problem that the driving force on the two pressure beams is different, making it difficult for the cargo compartment to maintain balance during the tilting process. This results in poor flexibility and adaptability. In view of this, the present invention is proposed. Summary of the Invention

[0003] To address the problem of the carriage being difficult to maintain balance and deformed due to asynchronous rotation of the two pressure beams, this invention provides a connecting arm for the pressure beams and a carriage tilting device.

[0004] The connecting arm for pressing beams provided by the present invention includes a first connecting rod, a second connecting rod, a first adjusting component, and a second adjusting component. The first connecting rod includes a first connecting end and a first insertion end. The second connecting rod includes a second connecting end and a second insertion end. The first connecting end and the second connecting end are respectively connected to two pressing beams. The second insertion end is inserted into the first connecting rod from the first insertion end and forms a gap with the inner wall of the first connecting rod. The first adjusting component is disposed on the outer surface of the first connecting rod and abuts against the outer surface of the second connecting rod. The second adjusting component is disposed on the outer surface of the second connecting rod and abuts against the inner surface of the first connecting rod.

[0005] In an embodiment of the present invention, the first adjustment assembly includes an adjustment bolt and a first adjustment plate. A threaded hole is provided on the side wall of the first connecting rod near the first insertion end, which is threaded to the adjustment bolt. The first adjustment plate is located at the gap between the first connecting rod and the second connecting rod. The adjustment bolt passes through the threaded hole and abuts against the first adjustment plate, so that the first adjustment plate abuts against the outer surface of the second connecting rod.

[0006] In an embodiment of the present invention, a through hole adapted to the size of the first adjusting plate is provided on the side wall of the first connecting rod near the first insertion end. A sealing plate detachably connected to the first connecting rod is provided on the through hole to close the through hole, and a screw hole is provided on the sealing plate.

[0007] In an embodiment of the present invention, an annular boss is provided at the end of the adjusting bolt that abuts against the first adjusting plate, and a groove adapted to the size of the annular boss is provided on the first adjusting plate so as to drive the first adjusting plate to move when the adjusting bolt rotates.

[0008] In an embodiment of the present invention, the second adjustment assembly includes a second adjustment plate, which is detachably connected to the outer wall of the second connecting rod near the second insertion end, and the second adjustment plate is in contact with the inner wall of the first connecting rod.

[0009] In an embodiment of the present invention, an anti-slip pad is provided on the side of the first adjusting plate that is in contact with the second connecting rod; and / or an anti-slip pad is provided on the side of the second adjusting plate that is in contact with the first connecting rod.

[0010] In an embodiment of the present invention, both the first connecting rod and the second connecting rod are made of square steel, the diameter of the second connecting rod is smaller than the diameter of the first connecting rod, and both the first adjusting plate and the second adjusting plate are made of flat plates, so that the first adjusting plate abuts against the outer surface of the second connecting rod and the second adjusting plate abuts against the inner surface of the first connecting rod.

[0011] In an embodiment of the present invention, both the first connecting rod and the second connecting rod are circular tube structures, the diameter of the second connecting rod is smaller than the diameter of the first connecting rod, and both the first adjusting plate and the second adjusting plate are arc-shaped plates, so that the first adjusting plate abuts against the outer surface of the second connecting rod and the second adjusting plate abuts against the inner surface of the first connecting rod.

[0012] In an embodiment of the present invention, the first adjustment component and the second adjustment component are each provided in four sets. The four sets of first adjustment components are arranged around the first connecting rod array to abut against the outer surface of the second connecting rod, and the four sets of second adjustment components are arranged around the second connecting rod array to abut against the inner surface of the first connecting rod.

[0013] To address the aforementioned technical problems, this invention also provides a car body tipping device. The car body tipping device includes a tipper, two pressure beams, a detection component, and the aforementioned connecting arm. The two pressure beams are detachably connected to the car body. The connecting arm is hinged between the two pressure beams. The tipper is simultaneously connected to both pressure beams to drive them to rotate simultaneously and tip the car body. The detection component is signal-connected to the tipper and includes a laser emitter and a laser receiver suspended from a first connecting rod and a second connecting rod, respectively, to detect the rotational synchronicity of the two pressure beams. When the rotations of the two pressure beams are asynchronous, the tipper detects the deflection angle of the two pressure beams. The tipper corrects the rotation of the two pressure beams based on the deflection angle.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] By fixing the first and second hinge bases to the two pressing beams respectively, and connecting the first and second insertion ends, a gap is formed between the first and second connecting rods. This allows the first and second connecting rods to swing and extend relative to each other under the action of the gap. By adjusting the preload of the first adjusting component against the second connecting rod, and / or by adjusting the preload of the second adjusting component against the first connecting rod, the resistance during the relative extension and retraction of the first and second connecting rods is increased. This ensures that when the difference in driving force between the two pressing beams is less than this resistance, the force on the two pressing beams is transmitted and the force on the two pressing beams is kept balanced. This ensures that the carriage can be smoothly overturned and avoids the problem of inconsistent force exerted on the carriage by the pressing beams due to asynchronous rotation of the two pressing beams, which would cause deformation of the carriage. Conversely, when the difference in driving force between the two pressing beams is greater than or equal to this resistance, the first and second connecting rods swing and extend relative to each other under the action of the gap. This adapts to the changes in angle and length caused by asynchronous movement of the two pressing beams and avoids damage to the connecting arm. Attached Figure Description

[0023] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In existing wagon tilting operations, because both pressure beams are installed on the same side of the wagon, when the tilting machine drives the pressure beams to tilt the wagon, the force on the wagon is concentrated at the positions corresponding to the two pressure beams. At this time, the distribution of cargo inside the wagon affects the tilting machine's operation, making it difficult for the wagon to maintain balance during tilting. That is, when the tilting machine uses the same driving force to rotate the two pressure beams, the side with a larger cargo mass will tilt less than the side with a smaller cargo mass, thus... This imbalance during carriage tipping, exacerbated by the increasing tipping time, gradually amplifies the disparity between the two sides, eventually leading to deformation of the carriage's side walls. This negatively impacts the carriage's usability and can even cause damage. To avoid this, the present invention provides a general inventive concept: a connecting arm is installed between the two pressure beams to transmit the driving force between them, thereby maintaining balanced tipping and preventing uneven stress on both sides that could cause deformation. Specifically:

[0025] Please see Figures 1-3 , Figure 1 This is a three-dimensional structural diagram of the connecting arm connected to the press beam according to an embodiment of the present invention; Figure 2 This is an exploded structural diagram of the connecting arm connected to the pressure beam according to an embodiment of the present invention; Figure 3 yes Figure 2 Enlarged view at point A in the figure. The connecting arm 1 for the pressing beam of the present invention includes a first connecting rod 11, a second connecting rod 12, a first adjusting component 13, and a second adjusting component 14. The first connecting rod 11 includes a first connecting end 111 and a first insertion end 112. The second connecting rod 12 includes a second connecting end 121 and a second insertion end 122. The first connecting end 111 and the second connecting end 121 are respectively connected to two pressing beams 2. The second insertion end 122 is inserted into the first connecting rod 11 from the first insertion end 112 and forms a gap with the inner wall of the first connecting rod 11. The first adjusting component 13 is disposed on the outer surface of the first connecting rod 11 and abuts against the outer surface of the second connecting rod 12. The second adjusting component 14 is disposed on the outer surface of the second connecting rod 12 and abuts against the inner surface of the first connecting rod 11.

[0026] By connecting the first connecting end 111 and the second connecting end 121 to the two pressing beams 2 respectively, and connecting the first plug-in end 112 to the second plug-in end 122, the first connecting rod 11 and the second connecting rod 12 can be connected between the two pressing beams 2. When it is necessary to tip over the carriage for unloading, the tipper can be connected to the two pressing beams 2 so that the two pressing beams 2 can be rotated simultaneously under the drive of the tipper, and the rotating pressing beams 2 can cause the carriage to tip over, thereby realizing the unloading operation of the goods in the carriage.

[0027] When the driving force of the tipper on the two pressure beams 2 is inconsistent, causing the car body to tip unbalanced, the force on one pressure beam 2 can be transferred to the other pressure beam 2 through the insertion connection of the first connecting rod 11 and the second connecting rod 12. This makes the force on the two pressure beams 2 tend to be the same. That is, when the driving force of the tipper on the two pressure beams 2 is different, the force on the two pressure beams 2 can be transferred under the action of the first connecting rod 11 and the second connecting rod 12, so that the force on the two pressure beams 2 is balanced and they tip synchronously. This ensures that the force of the two pressure beams 2 on the car body is balanced, so that the car body can tip smoothly. At the same time, it can also avoid the problem of deformation of the car body caused by the different forces on the two pressure beams 2.

[0028] In the above embodiment, after the first insertion end 112 and the second insertion end 122 are inserted, a gap is formed between the second connecting rod 12 and the first connecting rod 11. Under the action of the gap, the first connecting rod 11 and the second connecting rod 12 can extend and retract relative to each other, and at the same time, the first connecting rod 11 and the second connecting rod 12 can swing relative to each other. Therefore, under the action of the relative extension and retraction and swing of the first connecting rod 11 and the second connecting rod 12, it can adapt to the changes in length and angle caused by the asynchronous movement of the two pressure beams 2.

[0029] By providing a first adjusting component 13 on the first connecting rod 11 that abuts against the second connecting rod 12, the resistance of the first connecting rod 11 and the second connecting rod 12 during relative extension and contraction can be increased by adjusting the preload of the first adjusting component 13 against the second connecting rod 12. This allows the first connecting rod 11 and the second connecting rod 12 to remain relatively fixed when the difference in driving force between the two pressing beams 2 is less than this resistance. Under the action of the first connecting rod 11 and the second connecting rod 12, the force on the two pressing beams 2 is transmitted, thereby keeping the force on the two pressing beams 2 balanced. This ensures that the carriage can be smoothly overturned and avoids the problem of inconsistent force exerted on the carriage by the pressing beams 2 due to asynchronous rotation of the two pressing beams 2, which could cause deformation of the carriage.

[0030] When the difference in driving force between the two pressing beams 2 is greater than or equal to the resistance, the first connecting rod 11 and the second connecting rod 12 swing relative to each other under the action of the gap. At the same time, the first connecting rod 11 and the second connecting rod 12 are extended and retracted to adapt to the changes in angle and length caused by the asynchronous movement of the two pressing beams 2. This ensures that the first connecting rod 11 and the second connecting rod 12 are still connected between the two pressing beams 2, preventing the connecting arm 1 from being twisted or bent and thus damaged.

[0031] Similarly, by setting a second adjusting component 14 on the second connecting rod 12 that abuts against the first connecting rod 11, the resistance of the first connecting rod 11 and the second connecting rod 12 during relative extension and contraction can be increased by adjusting the preload of the second adjusting component 14 against the first connecting rod 11. Thus, when the difference in driving force on the two pressing beams 2 is less than this resistance, the first connecting rod 11 and the second connecting rod 12 can remain relatively fixed, and the force on the two pressing beams 2 can be transmitted under the action of the first connecting rod 11 and the second connecting rod 12, thereby keeping the force on the two pressing beams 2 balanced. This ensures that the carriage can be turned over smoothly and avoids the problem of inconsistent force on the carriage caused by the asynchronous rotation of the two pressing beams 2, which would cause deformation of the carriage.

[0032] When the difference in driving force between the two pressing beams 2 is greater than or equal to the resistance, the first connecting rod 11 and the second connecting rod 12 swing relative to each other under the action of the gap. At the same time, the first connecting rod 11 and the second connecting rod 12 are extended and retracted to adapt to the changes in angle and length caused by the asynchronous movement of the two pressing beams 2. This ensures that the first connecting rod 11 and the second connecting rod 12 are still connected between the two pressing beams 2, preventing the connecting arm 1 from being twisted or bent and thus damaged.

[0033] In an embodiment of the present invention, the first adjustment assembly 13 includes an adjustment bolt 132 and a first adjustment plate 131. The first connecting rod 11 has a threaded hole on its side wall near the first insertion end 112 for threaded connection with the adjustment bolt 132. The first adjustment plate 131 is located at the gap between the first connecting rod 11 and the second connecting rod 12. The adjustment bolt 132 passes through the threaded hole and abuts against the first adjustment plate 131, so that the first adjustment plate 131 abuts against the outer surface of the second connecting rod 12.

[0034] By opening a screw hole in the first connecting rod 11, the adjusting bolt 132 is threaded into the screw hole and passes through the screw hole to abut against the first adjusting plate 131. By turning the adjusting bolt 132, the adjusting bolt 132 abuts against the first adjusting plate 131 and the first adjusting plate 131 is attached to the outer surface of the second connecting rod 12. By continuing to turn the adjusting bolt 132, the first adjusting plate 131 and the second connecting rod 12 are attached more tightly, thereby adjusting the preload of the first adjusting plate 131 and the second connecting rod 12, increasing the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract relative to each other. Thus, when the difference in driving force on the two pressing beams 2 is less than this resistance, the first connecting rod 11 and the second connecting rod 12 can be kept relatively fixed, and the force on the two pressing beams 2 can be transmitted through the connecting arm 1 and the force on the two pressing beams 2 can be kept balanced.

[0035] In an embodiment of the present invention, the first connecting rod 11 has a through hole on its side wall near the first insertion end 112 that is adapted to the size of the first adjusting plate 131. A sealing plate 133 that is detachably connected to the first connecting rod 11 is provided on the through hole to close the through hole, and a screw hole is provided on the sealing plate 133.

[0036] By creating a through hole in the first connecting rod 11, allowing the second adjusting plate 141 to pass through and adhere to the outer surface of the second connecting rod 12, the first adjusting plate 131 is positioned at the gap between the first connecting rod 11 and the second connecting rod 12. A sealing plate 133 covers and fixes the sealing plate 133 to the through hole in the first connecting rod 11. An adjusting bolt 132 passes through the first adjusting plate 131 and connects to it. Thus, the distance between the first adjusting plate 131 and the sealing plate 133 can be adjusted under the action of the adjusting bolt 132, thereby adjusting the position of the first adjusting plate 131 relative to the outer surface of the second connecting rod 12. The preload is used to adjust the resistance when the first connecting rod 11 and the second connecting rod 12 extend. That is, when the preload of the first adjusting plate 131 against the outer surface of the second connecting rod 12 increases, the friction between the second connecting rod 12 and the first adjusting plate 131 increases, thereby increasing the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract. Conversely, when the preload of the first adjusting plate 131 against the outer surface of the second connecting rod 12 decreases, the friction between the second connecting rod 12 and the first adjusting plate 131 decreases, thereby reducing the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract.

[0037] In the above embodiment, the sealing plate 133 is bolted to the through hole of the first connecting rod 11 so that when the first adjusting plate 131 needs to be removed, the operator can remove the sealing plate 133 from the first connecting rod 11 and then remove the first adjusting plate 131 from the through hole, thereby improving the efficiency and convenience of replacing the first adjusting plate 131.

[0038] Please see Figure 4 , Figure 4 This is a partial exploded cross-sectional view of the first adjusting component in the connecting arm provided in an embodiment of the present invention. In the embodiment of the present invention, an annular boss 1321 is provided at the end of the adjusting bolt 132 that abuts against the first adjusting plate 131, and a groove 1311 adapted to the size of the annular boss 1321 is provided on the first adjusting plate 131 so as to drive the first adjusting plate 131 to move when the adjusting bolt 132 rotates.

[0039] By providing an annular boss 1321 at the end of the adjusting bolt 132 and a groove 1311 on the first adjusting plate 131, the adjusting bolt 132 is rotatably connected to the first adjusting plate 131 through the connection of the annular boss 1321 and the groove 1311. Thus, when the adjusting bolt 132 is turned, it can cause the adjusting bolt 132 to move the first adjusting plate 131. That is, under the action of the annular boss 1321, it abuts against the groove 1311 and moves the first adjusting plate 131 closer to the second connecting rod 12, or moves the first adjusting plate 131 away from the second connecting rod 12. This avoids the first adjusting plate 131 from detaching from the adjusting bolt 132, which would prevent the adjusting bolt 132 from adjusting the resistance between the first connecting rod 11 and the second connecting rod 12.

[0040] In an embodiment of the present invention, the second adjustment component 14 includes a second adjustment plate 141, which is detachably connected to the outer wall of the second connecting rod 12 near the second insertion end 122, and the second adjustment plate 141 is in contact with the inner wall of the first connecting rod 11.

[0041] By connecting the second adjusting plate 141 to the surface of the second connecting rod 12, the second adjusting plate 141 is made to fit against the inner wall of the first connecting rod 11. This allows the gap between the first connecting rod 11 and the second connecting rod 12 to be filled under the action of the second adjusting plate 141. By increasing or decreasing the thickness or number of the second adjusting plate 141, the pre-tightening force between the second adjusting plate 141 and the inner wall of the first connecting rod 11 can be adjusted, thereby regulating the resistance when the first connecting rod 11 and the second connecting rod 12 extend. Specifically, when the pre-tightening force of the second adjusting plate 141 against the inner surface of the first connecting rod 11 increases, the friction between the first connecting rod 11 and the second adjusting plate 141 increases, thus increasing the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract. Conversely, when the pre-tightening force of the second adjusting plate 141 against the inner surface of the first connecting rod 11 decreases, the friction between the first connecting rod 11 and the second adjusting plate 141 decreases, thus reducing the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract.

[0042] In an embodiment of the present invention, an anti-slip pad is provided on the side of the first adjusting plate 131 that is in contact with the second connecting rod 12, so as to increase the friction force when the first connecting rod 11 and the second connecting rod 12 extend and retract relative to each other under the action of the anti-slip pad, and at the same time, it can also prevent wear and scratches from occurring on the surfaces of the first adjusting plate 131 and the second connecting rod 12. The protective pad includes a rubber anti-slip pad and a plastic anti-slip pad.

[0043] In an embodiment of the present invention, an anti-slip pad is provided on the side of the second adjusting plate 141 that is in contact with the surface of the first connecting rod 11, so as to increase the frictional force when the first connecting rod 11 and the second connecting rod 12 extend and retract relative to each other under the action of the anti-slip pad, and at the same time, it can also prevent the second adjusting plate 141 from being worn and scratched on the surface of the first connecting rod 11. The protective pad includes a rubber anti-slip pad and a plastic anti-slip pad.

[0044] In an embodiment of the present invention, both the first connecting rod 11 and the second connecting rod 12 are made of square steel. The diameter of the second connecting rod 12 is smaller than the diameter of the first connecting rod 11. Both the first adjusting plate 131 and the second adjusting plate 141 are made of flat plates, so that the first adjusting plate 131 abuts against the outer surface of the second connecting rod 12, and the second adjusting plate 141 abuts against the inner surface of the first connecting rod 11.

[0045] By making both the first connecting rod 11 and the second connecting rod 12 into square steel structures, the structural strength of the first connecting rod 11 and the second connecting rod 12 is increased. Since the diameter of the second connecting rod 12 is smaller than the diameter of the first connecting rod 11, the second connecting rod 12 can be inserted into the first connecting rod 11 and a gap is formed between the first connecting rod 11 and the second connecting rod 12, so that the first adjusting component 13 and the second adjusting component 14 can be connected at the gap. The first adjusting component 13 adjusts the pre-tightening force against the second connecting rod 12, and the second adjusting component 14 adjusts the pre-tightening force against the first connecting rod 11, thereby realizing the adjustment of the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract, so as to transmit the driving force of the two pressing beams 2 when the two pressing beams 2 are out of sync, so that the forces on the two pressing beams 2 are balanced and they can be rotated synchronously.

[0046] Since both the first connecting rod 11 and the second connecting rod 12 are made of square steel, setting the first adjusting plate 131 and the second adjusting plate 141 as flat plates can increase the contact area with the first connecting rod 11 and the second connecting rod 12. That is, it increases the contact area when the first adjusting plate 131 is attached to the outer surface of the second connecting rod 12 and increases the contact area when the second adjusting plate 141 is attached to the inner surface of the first connecting rod 11, thereby realizing the adjustment of the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract.

[0047] In an embodiment of the present invention, both the first connecting rod 11 and the second connecting rod 12 adopt a circular tube structure. The diameter of the second connecting rod 12 is smaller than the diameter of the first connecting rod 11. Both the first adjusting plate 131 and the second adjusting plate 141 adopt an arc-shaped plate so that the first adjusting plate 131 abuts against the outer surface of the second connecting rod 12, and the second adjusting plate 141 abuts against the inner surface of the first connecting rod 11.

[0048] By designing both the first connecting rod 11 and the second connecting rod 12 as circular tubes, they can rotate relative to each other axially after being inserted and connected. Since the diameter of the second connecting rod 12 is smaller than that of the first connecting rod 11, the second connecting rod 12 can be inserted into the first connecting rod 11, forming a gap between the first connecting rod 11 and the second connecting rod 12. This gap allows the first adjusting component 13 and the second adjusting component 14 to connect at the gap. The first adjusting component 13 adjusts the pre-tightening force against the second connecting rod 12, and the second adjusting component 14 adjusts the pre-tightening force against the first connecting rod 11. This adjusts the resistance during the extension and retraction of the first connecting rod 11 and the second connecting rod 12, so that the driving force of the two pressing beams 2 can be transmitted when they are out of sync, so that the forces on the two pressing beams 2 remain balanced and they can rotate synchronously.

[0049] Since both the first connecting rod 11 and the second connecting rod 12 adopt a circular tube structure, setting the first adjusting plate 131 and the second adjusting plate 141 as arc-shaped plates can increase the contact area with the first connecting rod 11 and the second connecting rod 12. That is, it increases the contact area when the first adjusting plate 131 is attached to the outer surface of the second connecting rod 12 and increases the contact area when the second adjusting plate 141 is attached to the inner surface of the first connecting rod 11, thereby realizing the adjustment of the resistance when the first connecting rod 11 and the second connecting rod 12 extend and retract.

[0050] In an embodiment of the present invention, the first adjustment component 13 and the second adjustment component 14 are each provided in four sets. The four sets of first adjustment components 13 are arranged in an array around the first connecting rod 11 to abut against the outer surface of the second connecting rod 12, and the four sets of second adjustment components 14 are arranged in an array around the second connecting rod 12 to abut against the inner surface of the first connecting rod 11.

[0051] By configuring four sets of both the first adjusting assembly 13 and the second adjusting assembly 14, the four sets of first adjusting assemblies 13 are arrayed on the first connecting rod 11 and abut against the outer surfaces of the second connecting rod 12. This allows for individual adjustment of the preload between the first adjusting plate 131 and the second connecting rod 12 in the circumferential direction of the second connecting rod 12, which in turn allows for individual adjustment of the resistance during the extension and retraction of the first connecting rod 11 and the second connecting rod 12 in the circumferential direction. Similarly, four sets of second adjusting plates 141 are fixed around the second connecting rod 12 to allow for individual adjustment of the preload between the second adjusting plate 141 and the first connecting rod 11 in the circumferential direction of the second connecting rod 12, which in turn allows for individual adjustment of the resistance during the extension and retraction of the first connecting rod 11 and the second connecting rod 12 in the circumferential direction.

[0052] To address the problems in the prior art, this invention also provides a car body tipping device. The car body tipping device includes a tipper, two pressing beams 2, a detection component, and the aforementioned connecting arm 1. The two pressing beams 2 are detachably connected to the car body. The connecting arm 1 is hinged between the two pressing beams 2. The tipper is simultaneously connected to both pressing beams 2 to drive the two pressing beams 2 to rotate simultaneously and cause the car body to tip. The detection component is signal-connected to the tipper. The detection component includes a laser emitter and a laser receiver respectively suspended on a first connecting rod 11 and a second connecting rod 12 to detect the rotation synchronicity of the two pressing beams 2. When the rotation of the two pressing beams 2 is asynchronous, the deflection angle of the two pressing beams 2 is detected. The tipper corrects the rotation of the two pressing beams 2 according to the deflection angle.

[0053] By installing two pressure beams 2 on the car body and connecting the tipper to the two pressure beams 2, the tipper can drive the two pressure beams 2 to tilt the car body, thereby unloading the goods inside the car body. By hinged the connecting arm 1 between the two pressure beams 2, the connecting arm 1 can transmit the driving force on the two pressure beams 2 when the two tippers drive the two pressure beams 2 to rotate asynchronously, so that the forces on the two pressure beams 2 are balanced and they tilt synchronously. This ensures that the forces acting on the car body by the two pressure beams 2 are balanced, allowing the car body to tilt smoothly. At the same time, it can also avoid the problem of deformation of the car body caused by different forces on the two pressure beams 2.

[0054] In the above embodiment, there are a first connecting rod 11, a second connecting rod 12, a first adjusting component 13, and a second adjusting component 14. The first connecting rod 11 includes a first connecting end 111 and a first insertion end 112. The second connecting rod 12 includes a second connecting end 121 and a second insertion end 122. The first connecting end 111 and the second connecting end 121 are respectively connected to two pressing beams 2. The second insertion end 122 is inserted into the first connecting rod 11 from the first insertion end 112 and forms a gap with the inner wall of the first connecting rod 11. The first adjusting component 13 is disposed on the outer surface of the first connecting rod 11 and abuts against the outer surface of the second connecting rod 12. The second adjusting component 14 is disposed on the outer surface of the second connecting rod 12 and abuts against the inner surface of the first connecting rod 11.

[0055] By connecting the first connecting end 111 and the second connecting end 121 to the two pressing beams 2 respectively, and connecting the first plug-in end 112 to the second plug-in end 122, the first connecting rod 11 and the second connecting rod 12 can be connected between the two pressing beams 2. When it is necessary to tip over the carriage for unloading, the tipper can be connected to the two pressing beams 2 so that the two pressing beams 2 can be rotated simultaneously under the drive of the tipper, and the rotating pressing beams 2 can cause the carriage to tip over, thereby realizing the unloading operation of the goods in the carriage.

[0056] When the driving force of the tipper on the two pressure beams 2 is inconsistent, causing the car body to tip unbalanced, the force on one pressure beam 2 can be transferred to the other pressure beam 2 through the insertion connection of the first connecting rod 11 and the second connecting rod 12. This makes the force on the two pressure beams 2 tend to be the same. That is, when the driving force of the tipper on the two pressure beams 2 is different, the force on the two pressure beams 2 can be transferred under the action of the first connecting rod 11 and the second connecting rod 12, so that the force on the two pressure beams 2 is balanced and they tip synchronously. This ensures that the force of the two pressure beams 2 on the car body is balanced, so that the car body can tip smoothly. At the same time, it can also avoid the problem of deformation of the car body caused by the different forces on the two pressure beams 2.

[0057] In the above embodiment, after the first insertion end 112 and the second insertion end 122 are inserted, a gap is formed between the second connecting rod 12 and the first connecting rod 11. Under the action of the gap, the first connecting rod 11 and the second connecting rod 12 can extend and retract relative to each other, and at the same time, the first connecting rod 11 and the second connecting rod 12 can swing relative to each other. Therefore, under the action of the relative extension and retraction and swing of the first connecting rod 11 and the second connecting rod 12, it can adapt to the changes in length and angle caused by the asynchronous movement of the two pressure beams 2.

[0058] By providing a first adjusting component 13 on the first connecting rod 11 that abuts against the second connecting rod 12, the resistance of the first connecting rod 11 and the second connecting rod 12 during relative extension and contraction can be increased by adjusting the preload of the first adjusting component 13 against the second connecting rod 12. This allows the first connecting rod 11 and the second connecting rod 12 to remain relatively fixed when the difference in driving force between the two pressing beams 2 is less than this resistance. Under the action of the first connecting rod 11 and the second connecting rod 12, the force on the two pressing beams 2 is transmitted, thereby keeping the force on the two pressing beams 2 balanced. This ensures that the carriage can be smoothly overturned and avoids the problem of inconsistent force exerted on the carriage by the pressing beams 2 due to asynchronous rotation of the two pressing beams 2, which could cause deformation of the carriage.

[0059] When the difference in driving force between the two pressing beams 2 is greater than or equal to the resistance, the first connecting rod 11 and the second connecting rod 12 swing relative to each other under the action of the gap. At the same time, the first connecting rod 11 and the second connecting rod 12 are extended and retracted to adapt to the changes in angle and length caused by the asynchronous movement of the two pressing beams 2. This ensures that the first connecting rod 11 and the second connecting rod 12 are still connected between the two pressing beams 2, preventing the connecting arm 1 from being twisted or bent and thus damaged.

[0060] Similarly, by setting a second adjusting component 14 on the second connecting rod 12 that abuts against the first connecting rod 11, the resistance of the first connecting rod 11 and the second connecting rod 12 during relative extension and contraction can be increased by adjusting the preload of the second adjusting component 14 against the first connecting rod 11. Thus, when the difference in driving force on the two pressing beams 2 is less than this resistance, the first connecting rod 11 and the second connecting rod 12 can remain relatively fixed, and the force on the two pressing beams 2 can be transmitted under the action of the first connecting rod 11 and the second connecting rod 12, thereby keeping the force on the two pressing beams 2 balanced. This ensures that the carriage can be turned over smoothly and avoids the problem of inconsistent force on the carriage caused by the asynchronous rotation of the two pressing beams 2, which would cause deformation of the carriage.

[0061] When the difference in driving force between the two pressing beams 2 is greater than or equal to the resistance, the first connecting rod 11 and the second connecting rod 12 swing relative to each other under the action of the gap. At the same time, the first connecting rod 11 and the second connecting rod 12 are extended and retracted to adapt to the changes in angle and length caused by the asynchronous movement of the two pressing beams 2. This ensures that the first connecting rod 11 and the second connecting rod 12 are still connected between the two pressing beams 2, preventing the connecting arm 1 from being twisted or bent and thus damaged.

[0062] By suspending the laser emitter and laser receiver on the first connecting rod 11 and the second connecting rod 12 respectively, the laser receiver can receive the laser beam emitted by the laser emitter. The position of the laser beam on the laser receiver can be used to determine whether the rotation of the two pressure beams 2 is synchronized. The offset distance of the laser beam on the laser receiver can be used to detect the deflection angle of the two pressure beams 2, so that the tipper can correct the rotation driving force of the two pressure beams 2 according to the deflection angle.

[0063] In one embodiment, the laser emitter is suspended on the left-side pressure beam 2, and the laser receiver is suspended on the right-side pressure beam 2. When the laser beam illuminates the center of the laser receiver, the position of the laser beam indicates that the rotation of the two pressure beams 2 is synchronized. When the laser beam illuminates a position slightly below the center of the laser receiver, the position of the right-side pressure beam 2 indicates that it is too low. The offset distance is then calculated based on the distance between the center of the laser beam and the center of the laser receiver. A triangle is constructed based on the position of the laser emitter, the center of the laser receiver, and the actual position of the laser beam illuminating the laser receiver. Finally, the deflection angle of the two pressure beams 2 is calculated by combining the offset distance and trigonometric functions. The tipper then reduces the driving force on the right-side pressure beam 2 according to the deflection angle until the laser beam illuminates the center of the laser receiver. This corrects the rotational driving force of the two pressure beams 2, ensuring that the two pressure beams 2 rotate synchronously and drive the carriage to tip smoothly, avoiding the deformation of the carriage caused by the different forces exerted by the two pressure beams 2 on the carriage.
