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 then drives the pressure beam to tilt the cargo compartment, emptying the cargo. To ensure balance during tilting, two pressure beams are typically fixed to the same side of the cargo compartment so that the tipper can simultaneously drive both beams and tilt the compartment. However, in actual operation, it is difficult for the tipper to maintain the same driving force on the two pressure beams, resulting in asynchronous rotation. This makes it difficult for the cargo compartment to maintain balance during tilting and causes deformation due to the different forces exerted by the two pressure beams on the compartment. Therefore, this invention is proposed. Summary of the Invention

The portion of the first support rod that passes through the second support plate is provided with an external thread for the first nut to be threadedly connected. The fourth support plate has a through hole for the second support rod to pass through.

Furthermore, the relative extension and retraction of the first and second connecting rods, combined with the hinges between the first and second connecting rods and the first and second connecting bases, accommodates changes in length and angle when the two pressing beams rotate asynchronously, preventing the connecting arms from twisting and causing damage.

[0027] 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.

[0028] Please see Figures 1-2 , 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 connection provided in an embodiment of the present invention. 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 connecting base 13, and a second connecting base 14. The first connecting base 13 and the second connecting base 14 are respectively fixed on two pressing beams 2. 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 is rotatably connected to the first connecting base 13, and the second connecting end 121 is rotatably connected to the second connecting base 14. The first connecting rod 11 and the second connecting rod 12 are inserted and connected under the action of the first insertion end 112 and the second insertion end 122.

[0029] By rotatably connecting the first connecting rod 11 to the first connecting base 13, and rotatably connecting the second connecting rod 12 to the second connecting base 14, and fixing the first connecting base 13 and the second connecting base 14 to the two pressure beams 2 respectively, while simultaneously connecting the first connecting rod 11 and the second connecting rod 12 with an insert connection, the tipper can be connected to the two pressure beams 2 when it is necessary to tip the car body over for unloading. Driven by the tipper, the two pressure beams 2 will rotate simultaneously, causing the rotating pressure beams 2 to tip the car body. When the driving force of the tipper on the two pressure beams 2 is inconsistent, resulting in an unbalanced tipping of the car body, the tipper can be used to adjust the tipping mechanism. The force on one of the pressure beams 2 is transferred to the other pressure beam 2 through the plug-in connection of the connecting rod 11 and the second connecting rod 12, so that the force on the two pressure beams 2 tends 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 can be flipped synchronously. This ensures that the force on the car body by the two pressure beams 2 is balanced, so that the car body can be flipped 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.

[0030] In the above embodiment, the first connecting rod 11 and the second connecting rod 12 are connected by a transition fit. When the difference in driving force between the two pressing beams 2 is less than a preset value, the first connecting rod 11 and the second connecting rod 12 are kept relatively fixed and the force on the two pressing beams 2 is transmitted under the action of the first connecting rod 11 and the second connecting rod 12, so that the force on the two pressing beams 2 is kept balanced, thereby ensuring that the carriage can be turned over smoothly. When the difference in driving force between the two pressing beams 2 is greater than or equal to the preset value, the first connecting rod 11 and the second connecting rod 12 are extended and retracted relative to each other. At the same time, under the rotational connection between the first connecting rod 11 and the first connecting base 13, the first connecting rod 11 rotates relative to the first connecting base 13. Under the rotational connection between the second connecting rod 12 and the second connecting base 14, the second connecting rod 12 rotates relative to the second connecting base 14 to adapt to the changes in length and angle when the two pressing beams 2 rotate asynchronously, and to prevent the connecting arm 1 from twisting and being damaged.

[0031] Please see Figures 3-4 , Figure 3 This is an exploded structural diagram of the connecting arm connection provided in another embodiment of the present invention; Figure 4This is an exploded structural diagram of a connecting arm connection provided in another embodiment of the present invention. In this embodiment, the first connecting rod 11 includes a first support plate 114, a second support plate 115, and at least two first support rods 113, wherein the first support plate 114 and the second support plate 115 are respectively connected to both sides of the at least two first support rods 113, the first connecting end 111 is disposed on the first support plate 114, and the first insertion end 112 is formed on the second support plate 115;

[0032] By setting a first support plate 114 and a second support plate 115 at both ends of at least two first support rods 113, a first connecting end 111 can be set on the first support plate 114, and a first insertion end 112 can be opened on the second support plate 115, so that the first connecting end 111 is rotatably connected to the first connecting base 13, and the first connecting rod 11 and the second connecting rod 12 are inserted and connected under the action of the first insertion end 112 and the second insertion end 122. Under the action of at least two first support rods 113, the structural strength of the first connecting rod 11 is improved. In this way, when the two pressing beams 2 rotate asynchronously, the first connecting rod 11 and the second connecting rod 12 transmit the driving force on the two pressing beams 2, and keep the force on the two pressing beams 2 balanced, preventing the connecting arm 1 from twisting and being damaged when transmitting the driving force on the two pressing beams 2.

[0033] The second connecting rod 12 includes a third support plate 124, a fourth support plate 125, and at least two second support rods 123. The third support plate 124 and the fourth support plate 125 are respectively connected to the two sides of the at least two second support rods 123. The second connecting end 121 is disposed on the third support plate 124, and the second plug-in end 122 is opened on the fourth support plate 125.

[0034] By setting a third support plate 124 and a fourth support plate 125 at both ends of at least two second support rods 123, the second connecting end 121 can be set on the third support plate 124, and the second insertion end 122 can be opened on the fourth support plate 125, so that the second connecting end 121 is rotatably connected to the second connecting base 14, and the first connecting rod 11 and the second connecting rod 12 are inserted and connected under the action of the first insertion end 112 and the second insertion end 122. Under the action of at least two second support rods 123, the structural strength of the second connecting rod 12 is improved. In this way, when the two pressing beams 2 rotate asynchronously, the first connecting rod 11 and the second connecting rod 12 transmit the driving force on the two pressing beams 2, and keep the force on the two pressing beams 2 balanced, preventing the connecting arm 1 from twisting and being damaged when transmitting the driving force on the two pressing beams 2.

[0035] In an embodiment of the present invention, at least two of the first support rods 113 pass through the fourth support plate 125 and are connected to the second support plate 115, with the second support plate 115 located between the three support plates and the fourth support plate 125; at least two of the second support rods 123 pass through the second support plate 115 and are connected to the fourth support plate 125, with the fourth support plate 125 located between the first support plate 114 and the second support plate 115.

[0036] Since at least two first support rods 113 in the first connecting rod 11 pass through the fourth support plate 125 and connect to the second support plate 115, and at least two second support rods 123 in the second connecting rod 12 pass through the second support plate 115 and connect to the fourth support plate 125, the first connecting rod 11 and the second connecting rod 12 can extend and retract relative to each other under the plug-in connection, and the second support plate 115 is located between the third support plate and the fourth support plate 125. At the same time, the fourth support plate 125 is located between the first support plate 114 and the second support plate 115, so as to limit the extension distance of the first connecting rod 11 and the second connecting rod 12 under the action of the first plug-in end 112 and the second plug-in end 122, and avoid the first connecting rod 11 and the second connecting rod 12 from separating.

[0037] Please see Figure 5 , Figure 5 This is a partial cross-sectional view of the connecting arm provided in an embodiment of the present invention. In this embodiment, there are four first support rods 113, which are arranged in an array around the four vertices of a first rectangle 119 between the first support plate 114 and the second support plate 115.

[0038] The number of the second support rods 123 is four, and the four second support rods 123 are distributed in an array around the four vertices of the second rectangle 129 between the third support plate 124 and the fourth support plate 125.

[0039] By setting four first support rods 113 in the first connecting rod 11 and four second support rods 123 in the second connecting rod 12, and arranging the four first support rods 113 in an array around the four vertices of the first rectangle 119 between the first support plate 114 and the second support plate 115, and the four second support rods 123 in an array around the four vertices of the second rectangle 129 between the third support plate 124 and the fourth support plate 125, the structural strength of the first connecting rod 11 can be enhanced by the action of the four first support rods 113. The structural strength of the second connecting rod 12 is enhanced by the action of 23, and the four first support rods 113 are distributed in an array along the four vertices of the first rectangle 119 so as to transmit the external force on the first connecting rod 11 under the action of the four first support rods 113 and make the force on the first connecting rod 11 evenly distributed on the four first support rods 113. Similarly, the external force on the second connecting rod 12 is transmitted under the action of the four second support rods 123 and the force on the second connecting rod 12 is evenly distributed on the four second support rods 123, further improving the structural strength of the connecting arm 1.

[0040] In the above embodiment, the insertion of the first connecting rod 11 and the second connecting rod 12 adopts a transition fit method. That is, after the four first support rods 113 pass through the fourth support plate 125, they transition fit with the fourth support plate 125, and after the four second support rods 123 pass through the second support plate 115, they transition fit with the second support plate 115. This allows the first connecting rod 11 and the second connecting rod 12 to remain relatively fixed while also allowing relative sliding. This ensures that when the difference in driving force between the two pressure beams 2 is less than a preset value, the first connecting rod 11 and the second connecting rod 12 can move together. The connecting rod 12 remains relatively fixed so as to transmit driving force under the action of the connecting arm 1 so that the two pressing beams 2 can rotate synchronously, thereby keeping the carriage smoothly overturned. When the difference in driving force received by the two pressing beams 2 is greater than a preset value, the first connecting rod 11 and the second connecting rod 12 slide relative to each other. At the same time, the first connecting rod 11 rotates around the first connecting base 13 and the second connecting rod 12 rotates around the second connecting base 14 to adapt to the changes in length and angle that occur when the two pressing beams 2 rotate asynchronously, and to prevent the connecting arm 1 from twisting and being damaged.

[0041] In an embodiment of the present invention, after the first connecting rod 11 and the second connecting rod 12 are inserted, the four first support rods 113 and the four second support rods 123 are staggered with each other. The first support rod 113 in the upper left corner of the first rectangle 119 is located at the center of the second rectangle 129, and the second support rod 123 in the lower right corner of the second rectangle 129 is located at the center of the first rectangle 119.

[0042] Because the four first support rods 113 and the four second support rods 123 are staggered, the structural strength of the first connecting rod 11 and the second connecting rod 12 after insertion and connection can be increased, and the first connecting rod 11 and the second connecting rod 12 can transmit external forces to each other when subjected to external forces, so that the force on the first connecting rod 11 and the second connecting rod 12 is consistent, and the phenomenon of damage caused by excessive external forces on either the first connecting rod 11 or the second connecting rod 12 is avoided.

[0043] In the above embodiment, the first support rod 113 at the upper left corner of the first rectangle 119 is located at the center of the second rectangle 129, and the second support rod 123 at the lower right corner of the second rectangle 129 is located at the center of the first rectangle 119, thereby achieving mutual misalignment of the four first support rods 113 and the four second support rods 123, and increasing the structural strength after the first connecting rod 11 and the second connecting rod 12 are connected by insertion.

[0044] Please see Figure 4 In an embodiment of the present invention, the connecting arm 1 includes a first nut 116 and a second nut 126. The second support plate 115 has a through hole through which the first support rod 113 passes. The portion of the first support rod 113 that passes through the second support plate 115 is provided with an external thread for the first nut 116 to be threadedly connected. The fourth support plate 125 has a through hole through which the second support rod 123 passes. The portion of the second support rod 123 that passes through the fourth support plate 125 is provided with an external thread for the second nut 126 to be threadedly connected.

[0045] By creating a through hole in the second support plate 115, allowing the first support rod 113 to pass through, and threading the first nut 116 onto the protruding portion of the first support rod 113, a fixed connection is achieved between the first support rod 113 and the second support plate 115. Similarly, by creating a through hole in the fourth support plate 125, allowing the second support rod 123 to pass through, and threading the second nut 126 onto the protruding portion of the second support rod 123, a fixed connection is achieved. This achieves a fixed connection between the second support rod 123 and the fourth support plate 125, so that when it is necessary to disassemble the first connecting rod 11 and the second connecting rod 12, the first nut 116 is unscrewed from the first support rod 113 to remove the second support plate 115 from the first support rod 113. Then, by pulling the first support plate 114, the first support rod 113 is pulled out from the fourth support plate 125, thereby completing the disassembly of the first connecting rod 11 and the second connecting rod 12.

[0046] When disassembling the first connecting rod 11 and the second connecting rod 12, the fourth support plate 125 can be removed from the second support rod 123 by unscrewing the second nut 126 from the second support rod 123. Then, the third support plate 124 is pulled, causing the second support rod 123 to be pulled out from the second support plate 115, thereby completing the disassembly of the first connecting rod 11 and the second connecting rod 12.

[0047] Please see Figure 3 In another embodiment of the present invention, the connecting arm 1 includes a first bolt 117 and a second bolt 127. The second support plate 115 has a through hole for the first bolt 117 to pass through. The first support rod 113 has an internal thread for the first bolt 117 to be threaded through at one end near the through hole. The fourth support plate 125 has a through hole for the second bolt 127 to pass through. The second support rod 123 has an internal thread for the second bolt 127 to be threaded through at one end near the through hole.

[0048] By opening a through hole in the second support plate 115, a first bolt 117 is allowed to pass through the through hole and be threaded to the first support rod 113, thereby achieving a fixed connection between the first support rod 113 and the second support plate 115. Similarly, by opening a through hole in the fourth support plate 125, a second bolt 127 is allowed to pass through the through hole and be threaded to the second support rod 123, thereby achieving a fixed connection between the second support rod 123 and the fourth support plate 125. This allows for easy disassembly of the first connecting rod 11 and the second connecting rod 12 when necessary. The first bolt 117 is unscrewed from the first support rod 113 to remove the second support plate 115 from the first support rod 113. Then, by pulling the first support plate 114, the first support rod 113 is pulled out from the fourth support plate 125, thus completing the disassembly of the first connecting rod 11 and the second connecting rod 12.

[0049] When disassembling the first connecting rod 11 and the second connecting rod 12, the fourth support plate 125 can be removed from the second support rod 123 by unscrewing the second bolt 127. Then, the third support plate 124 is pulled, causing the second support rod 123 to be pulled out from the second support plate 115, thereby completing the disassembly of the first connecting rod 11 and the second connecting rod 12.

[0050] In an embodiment of the present invention, the first insertion end 112 is a first insertion hole opened on the second support plate 115 for the second support rod 123 to be inserted into, and the size of the first insertion hole is adapted to the size of the second support rod 123. The second insertion end 122 is a second insertion hole opened on the fourth support plate 125 for the first support rod 113 to be inserted into, and the size of the second insertion hole is adapted to the size of the first support rod 113.

[0051] By opening a first insertion hole on the second support plate 115 that matches the size of the second support rod 123, the second support rod 123 is inserted through the first insertion hole and transitions into the first insertion hole. Similarly, by opening a second insertion hole on the fourth support plate 125 that matches the size of the first support rod 113, the first support rod 113 is inserted through the second insertion hole and transitions into the second insertion hole. This achieves the insertion connection of the first connecting rod 11 and the second connecting rod 12, allowing the first connecting rod 11 and the second connecting rod 12 to remain relatively fixed while also sliding relative to each other. Thus, when the difference in driving force received by the two pressing beams 2 is less than a preset value, the first connecting rod 11 and the second connecting rod 12 remain relatively fixed, and under the action of the connecting arm 1, the driving force is transmitted so that the two pressing beams 2 can rotate synchronously.

[0052] In an embodiment of the present invention, both the first connecting base 13 and the second connecting base 14 are equipped with hydraulic rotary drive devices, so that the hydraulic rotary drive devices simultaneously drive the first connecting rod 11 and the second connecting rod 12 to rotate synchronously in the first direction.

[0053] By fixing the first connecting base 13 and the second connecting base 14 to the two pressing beams 2 respectively, the first connecting end 111 is fixed to the first connecting base 13 and the second connecting end 121 is fixed to the second connecting base 14. Thus, when the first connecting base 13 and the second connecting base 14 work simultaneously, the first connecting end 111 and the second connecting end 121 can drive the first connecting rod 11 and the second connecting rod 12 to rotate simultaneously. This adapts to the angle changes that occur when the two pressing beams 2 rotate asynchronously, and avoids the phenomenon that the first connecting rod 11 and the second connecting rod 12 cannot adapt to the angle changes that occur when the two pressing beams 2 rotate asynchronously, which would cause the connecting arm 1 to twist.

[0054] To address the problems in the prior art, the present invention also provides a car body tilting device, which includes a tipper, two pressing beams 2 and the aforementioned connecting arm 1. The two pressing beams 2 are detachably connected to the car body, and the connecting arm 1 is hinged between the two pressing beams 2. The tipper is simultaneously connected to the two pressing beams 2 to drive the two pressing beams 2 to rotate simultaneously and tilt the car body.

[0055] 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.

[0056] In the above embodiment, the connecting arm 1 includes a first connecting rod 11, a second connecting rod 12, a first connecting base 13, and a second connecting base 14. The first connecting base 13 and the second connecting base 14 are respectively fixed on two pressing beams 2. 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 is rotatably connected to the first connecting base 13, and the second connecting end 121 is rotatably connected to the second connecting base 14. The first insertion end 112 and the second insertion end 122 are inserted into each other to allow the first connecting rod 11 and the second connecting rod 12 to extend and retract relative to each other.

[0057] By rotatably connecting the first connecting rod 11 to the first connecting base 13, and rotatably connecting the second connecting rod 12 to the second connecting base 14, and fixing the first connecting base 13 and the second connecting base 14 to the two pressure beams 2 respectively, while simultaneously connecting the first connecting rod 11 and the second connecting rod 12 with an insert connection, the tipper can be connected to the two pressure beams 2 when it is necessary to tip the car body over for unloading. Driven by the tipper, the two pressure beams 2 will rotate simultaneously, causing the rotating pressure beams 2 to tip the car body. When the driving force of the tipper on the two pressure beams 2 is inconsistent, resulting in an unbalanced tipping of the car body, the tipper can be used to adjust the tipping mechanism. The force on one of the pressure beams 2 is transferred to the other pressure beam 2 through the plug-in connection of the connecting rod 11 and the second connecting rod 12, so that the force on the two pressure beams 2 tends 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 can be flipped synchronously. This ensures that the force on the car body by the two pressure beams 2 is balanced, so that the car body can be flipped 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.

[0058] In the above embodiment, the first connecting rod 11 and the second connecting rod 12 are connected by a transition fit. When the difference in driving force between the two pressing beams 2 is less than a preset value, the first connecting rod 11 and the second connecting rod 12 are kept relatively fixed and the force on the two pressing beams 2 is transmitted under the action of the first connecting rod 11 and the second connecting rod 12, so that the force on the two pressing beams 2 is kept balanced, thereby ensuring that the carriage can be turned over smoothly. When the difference in driving force between the two pressing beams 2 is greater than or equal to the preset value, the first connecting rod 11 and the second connecting rod 12 are extended and retracted relative to each other. At the same time, under the rotational connection between the first connecting rod 11 and the first connecting base 13, the first connecting rod 11 rotates relative to the first connecting base 13. Under the rotational connection between the second connecting rod 12 and the second connecting base 14, the second connecting rod 12 rotates relative to the second connecting base 14 to adapt to the changes in length and angle when the two pressing beams 2 rotate asynchronously, and to prevent the connecting arm 1 from twisting and being damaged.

[0059] In an embodiment of the present invention, the first connecting rod 11 includes a first support plate 114, a second support plate 115, and at least two first support rods 113, wherein the first support plate 114 and the second support plate 115 are respectively connected to both sides of the at least two first support rods 113, the first connecting end 111 is disposed on the first support plate 114, and the first plug-in end 112 is formed on the second support plate 115.

[0060] By setting a first support plate 114 and a second support plate 115 at both ends of at least two first support rods 113, the first connecting end 111 can be set on the first support plate 114, and the first insertion end 112 can be opened on the second support plate 115, so that the first connecting end 111 is rotatably connected to the first connecting base 13, and the first insertion end 112 is inserted into the second insertion end 122. Under the action of at least two first support rods 113, the structural strength of the first connecting rod 11 is improved. In this way, when the two pressing beams 2 rotate asynchronously, the first connecting rod 11 and the second connecting rod 12 can transmit the driving force on the two pressing beams 2, and keep the force on the two pressing beams 2 balanced, preventing the connecting arm 1 from twisting and being damaged when transmitting the driving force on the two pressing beams 2.

[0061] The second connecting rod 12 includes a third support plate 124, a fourth support plate 125, and at least two second support rods 123. The third support plate 124 and the fourth support plate 125 are respectively connected to the two sides of the at least two second support rods 123. The second connecting end 121 is disposed on the third support plate 124, and the second plug-in end 122 is opened on the fourth support plate 125.

[0062] By setting a third support plate 124 and a fourth support plate 125 at both ends of at least two second support rods 123 respectively, the second connecting end 121 can be set on the third support plate 124, and the second insertion end 122 can be opened on the fourth support plate 125, so that the second connecting end 121 is rotatably connected to the second connecting base 14, and the first insertion end 112 is inserted into the second insertion end 122. Under the action of at least two second support rods 123, the structural strength of the second connecting rod 12 is improved. In this way, when the two pressing beams 2 rotate asynchronously, the first connecting rod 11 and the second connecting rod 12 transmit the driving force on the two pressing beams 2, and keep the force on the two pressing beams 2 balanced, preventing the connecting arm 1 from twisting and being damaged when transmitting the driving force on the two pressing beams 2.
