Description

Technical Field

[0001] This invention relates to the field of transportation-related technologies, and in particular to an overload interception device for transportation and logistics. Background Technology

[0002] In the process of transportation, especially for long-distance transportation across regions, in order to ensure road traffic safety, inspections are usually set up at various traffic checkpoints. Vehicles pass through special vehicle weighbridges to display the actual load of the vehicle, thereby determining whether the vehicle is overloaded.

[0003] In actual reports, we often see drivers arguing with control personnel during weighing due to overloading or other issues, leading to dangerous acts such as running over checkpoints. Since transport vehicles are heavy and difficult to control, accidents involving them are usually quite serious. Therefore, there is a need for an overload prevention device for transportation and logistics to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing an overload interception device for transportation and logistics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] An adjusting screw is set on the inner surface of the support frame and connected by a bearing, with an adjusting motor installed at one end.

[0013] The sliding groove is located at the center of the outer surface of the support frame. Several sets of sliding seats are slidably installed inside the groove. The sets of sliding seats are evenly distributed in the sliding groove, with two sliding seats in each set. A support shaft hole is opened at the center of one side surface of the sliding seat, and an internal threaded adjusting sleeve is provided on the other side of the sliding seat and fitted onto the adjusting screw.

[0014] The support hole is opened on the side surface of the support frame and is located on both sides of the sliding groove; it is a through hole.

[0015] The support cylinders are located at the four corners of the center inside the support platform, with their telescopic ends facing downwards, and the support base plate is installed at their telescopic ends.

[0016] An adjustable roller box mechanism is installed on both sides of the weighbridge body and located on both sides of the support groove, and includes:

[0017] A square box is set on both sides of the weighbridge body. It is connected to the weighbridge body through several rotating seats. One end of the box is located on the weighbridge body, and the other end is placed on the ground.

[0018] Adjusting screws are located at both ends inside the square housing, and the two adjusting screws are connected by a synchronous pulley and a synchronous belt. One end of one of the adjusting screws is equipped with a drive motor, which is located outside the square housing.

[0019] The sliding adjustment frame is located inside the square box and is slidably connected to the square box and threadedly connected to the adjustment screw. The center of its side surface has a sliding groove identical to that of the support frame. Several sets of roller seats are slidably installed in the sliding groove. Each set of roller seats consists of two roller seats, which correspond to the position of the sliding seats. A fixed shaft is installed on the outside of the roller seats, and a support roller is installed on the fixed shaft.

[0020] Furthermore, after the fixed shaft extends out of the square box body as the sliding adjustment frame moves, one end of the fixed shaft is inserted into the support shaft hole of the corresponding sliding seat.

[0021] Furthermore, the roller seat and the sliding seat are adjusted using the same adjustment method, and the internal threaded adjusting sleeve, adjusting screw and adjusting motor used for adjustment are respectively set inside the sliding adjusting frame and the roller seat.

[0022] Furthermore, the adjusting screw is composed of several sets of positive thread screws and negative thread screws spliced ​​together, and each set of positive thread screws and negative thread screws is threadedly connected to the internal thread adjusting sleeve on the corresponding sliding seat and roller seat.

[0027] An overload interception device for transportation and logistics, manufactured using the technical solution of the present invention, has the following beneficial effects:

[0028] 1. The support roller is extended and inserted into the raised support platform. The position of the support roller is then adjusted using the adjusting screw, so that it moves closer to the vehicle's drive wheels. This lifts the vehicle's drive wheels off the ground. The rotation of the support roller can then restrain the vehicle on the weighbridge, preventing the transport vehicle from escaping during inspection and preventing it from being overloaded.

[0029] 2. By using multiple sets of support rollers, the device can limit overload resistance for various types of vehicles, thus expanding its application range.

[0030] 3. By using the support rollers to lift the drive wheels of the transport vehicle, the main weight of the vehicle can be borne on the weighbridge, thereby reducing the pressure on the support rollers and preventing tire blowouts, thus avoiding losses.

[0031] 4. By utilizing the support mechanism, the pressure on the support rollers can be fully transferred to the weighbridge when the transport vehicle is lifted, thereby ensuring the normal detection of the transport vehicle and avoiding deviations in the load of the transport vehicle.

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] Please see Figures 1 to 8 This application provides an overload interception device for transportation and logistics, including a weighbridge body 1, which is embedded in the ground, and a support groove 11, which is opened at the center of the weighbridge body 1 and at one end of the weighbridge body 1, and is spaced a certain distance from its end face.

[0046] In this embodiment of the invention, a support groove 11 is provided on the weighbridge body 1 and spaced a certain distance from one end of it. This ensures that when various types of transport vehicles drive onto the weighbridge, their drive wheels can move between the adjusting support mechanism 2 and the adjusting roller box mechanism 3. This facilitates the support of the drive wheels of the transport vehicles, preventing them from detaching from the weighbridge platform and thus avoiding the rotation of the drive wheels from causing the transport vehicles to move and thus preventing them from being blocked.

[0047] The support mechanism 12 is installed inside the weighbridge body 1 and located on both sides inside the support groove 11. It includes a fixed sleeve 121 installed at the four corners on both sides of the support groove 11, which is installed on the frame of the weighbridge body 1 and is horizontally arranged. A support column 122 is slidably installed in the fixed sleeve 121. An electric push rod 123 is installed on one side of the fixed sleeve 121, and its telescopic end is connected to the support column 122.

[0048] In this embodiment of the invention, by using the connection between the fixed sleeve 121 and the frame of the weighbridge body 1, the stability of the support column 122 can be ensured, so that when the drive wheels of the transport vehicle are supported, their load-bearing capacity is transferred to the frame of the weighbridge body 1, thereby ensuring that the weighbridge body can detect the weight of the transport vehicle. At the same time, it can also simplify the structure of the device and avoid excessive weighbridge cost.

[0049] In this embodiment of the invention, there are multiple fixed sleeves 121, which can be used to support the support platform 21, ensuring the stability of the support platform 21, dispersing the support pressure, and preventing the support column 122 from deforming due to excessive force.

[0050] Adjustable support mechanism 2 is set in support groove 11, and includes: support platform 21, which is embedded in support groove 11 and whose upper surface is at the same level as the weighbridge body 1. Support frames 211 are set at both ends of the platform, and support square tubes 212 are set on one side of support frames 211; lower support base 22 is located below both sides of support platform 21. Lower support square tubes 221 are set at both ends of the platform, and the lower support square tubes 221 are fixedly connected to the lower surface of support platform 21 and correspond to the positions of support square tubes 212 and support frames 211; support sleeves 222 are set at both ends of lower support square tubes 221 located outside lower support base 22. After support platform 21 is raised, support column 122 is movably inserted into support sleeve 222.

[0051] In this embodiment of the invention, the support platform 21 is used to fill the support groove 11, ensuring the integrity of the weighbridge body 1 itself, thereby facilitating the movement of transport vehicles on the weighbridge body 1 and preventing transport vehicles from falling into the support groove 11.

[0052] In this embodiment of the invention, by utilizing the lower support base 22 and the support sleeve 222 installed thereon, the support platform 21 can be raised and stably supported by the insertion of the support column 122, thereby facilitating the lifting of the drive wheels of the transport vehicle and preventing the transport vehicle from escaping.

[0053] In this embodiment of the invention, by using the lower support square tube 221, the structure of the support platform 21 itself can be guaranteed, while the support frame 221 can be strengthened, thereby ensuring the strength of the support platform 1 itself, and making the support platform 21 more stable when supporting the drive wheels of the transport vehicle.

[0054] An adjusting screw 23 is set on the inner surface of the support frame 211 and connected by a bearing. An adjusting motor 231 is set at one end of the adjusting screw 23. A sliding groove 24 is opened at the center of the outer surface of the support frame 211. Several sets of sliding seats 241 are slidably installed inside the sliding groove 24. The sets of sliding seats 241 are evenly distributed in the sliding groove 24. There are two sliding seats 241 in each set. A support shaft hole 242 is opened at the center of one side surface of the sliding seat 241. An internal thread adjusting sleeve 243 is set on the other side of the sliding seat 241 and is fitted onto the adjusting screw 23. A support hole 25 is opened on the side surface of the support frame 211 and is located on both sides of the sliding groove 24. It is a through hole.

[0055] In this embodiment of the invention, by setting up several sets of sliding seats 241 and using the threaded engagement of the adjusting screw 23 and the internal thread adjusting sleeve 243, the sliding seats 241 are adjusted so that the sliding seats 241 can drive the fixed shaft 332 and the support roller 333 to move. Then, the support roller 333 is used to squeeze the drive wheels of the transport vehicle, and by rotating the support roller 333, the drive wheels of the transport vehicle are separated from the weighbridge, thereby effectively preventing the transport vehicle from escaping.

[0056] In this embodiment of the invention, by utilizing the support hole 25, the support column 122 can be inserted into the support hole 25 after it extends out. Then, by using the connection of the support column 122, the support platform 21 is connected to the weighbridge body 1, thereby ensuring that the support platform 21 can be stably connected to the weighbridge body 1, while also facilitating the measurement of the load of the transport vehicle.

[0057] In this embodiment of the invention, by using multiple sets of sliding seats 241, the device can support the drive wheels of different types of vehicles, effectively improving the range of applications of the device and enabling it to meet the needs of different types of vehicles.

[0058] The support cylinder 26 is located at the four corners of the center inside the support platform 21, with its telescopic end facing downwards, and its telescopic end is equipped with the support base plate 261.

[0059] In this embodiment of the invention, by utilizing the support cylinder 26 and the support base plate 261, the lifting and lowering of the support platform 21 can be easily controlled, and the lifting and lowering of the drive wheels of the transport vehicle can be controlled, which facilitates the operation and control of the staff.

[0060] The adjustable roller box mechanism 3 is set on both sides of the weighbridge body 1 and on both sides of the support groove 11. It includes: a square box 31, which is set on both sides of the weighbridge body 1 and is connected to the weighbridge body 1 through several rotating seats 311. One end of the box is located on the weighbridge body 1 and the other end is placed on the ground.

[0061] The present invention is implemented in two ways. The square box 31 is connected to the weighbridge body 1 through several rotating seats 311, which can ensure the stability of the connection between the square box 31 and the weighbridge body 1, and at the same time ensure the load-bearing capacity of the square box 31.

[0062] In this embodiment of the invention, one end of the square box 31 is located on the weighbridge body 1, and the other end is placed on the ground. After the fixed shaft 332 and the support roller 333 extend out of the square box 31, their gravity can be used to gradually detach the square box 31 from the ground and press one end of it onto the weighbridge body 1, thereby allowing its overall weight to be borne by the weighbridge body 1. On the one hand, this facilitates the weighbridge body 1 to detect the weight of the transport vehicle, and on the other hand, it ensures the stability of the support for the drive wheels of the transport vehicle.

[0063] Adjusting screws 32 are located at both ends inside the square housing 31, and the two adjusting screws 32 are connected by a synchronous pulley 321 and a synchronous belt 322. One end of one adjusting screw 32 is equipped with a drive motor 323, which is located outside the square housing 31. A sliding adjusting frame 33 is located inside the square housing 31 and is slidably connected to the square housing 31 and threadedly connected to the adjusting screw 32. A sliding groove 24, identical to that of the support frame 211, is opened at the center of its side surface. Several sets of roller seats 331 are slidably installed in the sliding groove 24. Each set of roller seats 331 consists of two roller seats and corresponds to the position of the sliding seat 241. A fixed shaft 332 is installed on the outside of the roller seat 331, and a support roller 333 is provided on the fixed shaft 332.

[0064] In this embodiment of the invention, the adjustment screw 32 is driven to rotate by the drive motor 323, and through the transmission of the synchronous pulley 321 and the synchronous belt 322, it drives the sliding adjustment frame 33 to move through the threaded connection. This controls the extension of the fixed shaft 332 and the support roller 333. At the same time, by gradually extending the fixed shaft 332 and the support roller 333, the square box 31 is gradually adjusted to a horizontal position by gravity, which facilitates the insertion of the fixed shaft 332 into the support shaft hole 242.

[0065] In this embodiment of the invention, in order to ensure that the fixed shaft 332 is smoothly inserted into the support shaft hole 242, a caster wheel can be provided at one end of the fixed shaft 332 so that when the square box 31 is adjusted to a horizontal position by gravity, the fixed shaft 332 can be smoothly inserted into the support shaft hole 242 with the support of the caster wheel, thereby ensuring the stability of the device.

[0066] In this embodiment of the invention, the support roller 333 and the fixed shaft 332 are connected by a load-bearing bearing, allowing the support roller 333 to rotate freely on the fixed shaft 332. On the one hand, when the drive wheels of the transport vehicle are lifted, the rotation of the support roller 333 can quickly lift them, reducing frictional resistance with the tires. On the other hand, the rotation of the support roller 333 can also be used to prevent the transport vehicle from moving when it tries to escape, effectively preventing accidents and avoiding overloaded escape.

[0067] In this invention, after the fixed shaft 332 extends out of the square box 31 as the sliding adjustment frame 33 moves, one end of the fixed shaft 332 is inserted into the support shaft hole 242 of the corresponding sliding seat 241; this ensures the stability of the fixed shaft 332, thereby enabling it to smoothly lift the drive wheels of the transport vehicle.

[0068] In this invention, the roller seat 331 and the sliding seat 241 are adjusted using the same adjustment method. The internal threaded adjusting sleeve 243, adjusting screw 23 and adjusting motor 231 used for adjustment are respectively set inside the sliding adjusting frame 33 and the roller seat 331. By adopting the same method, the roller seat 331 and the sliding seat 241 are moved synchronously by the cooperation of the adjusting screw 23 and the internal threaded adjusting sleeve 243, so that the fixed shaft 332 can drive the support roller 333 to move, so that it can lift the drive wheel of the transport vehicle and detach it from the weighbridge body 1.

[0069] In this invention, the adjusting screw 23 is composed of several sets of positive thread screws and negative thread screws spliced ​​together, and each set of positive thread screws and negative thread screws is threadedly connected to the internal thread adjusting sleeve 243 on the corresponding sliding seat 241 and roller seat 331 respectively; by using the setting of positive thread screws and negative thread screws, each set of sliding seat 241 and roller seat 331 can move simultaneously toward the center of the drive wheel, thereby squeezing the drive wheel of the transport vehicle, and by using the rotation of the supporting roller 333, it can support the drive wheel.

[0070] In this invention, the adjustable roller box mechanism 3 and the adjustable support mechanism 2 are located on both sides of the vehicle's drive wheels; they can support the drive wheels of the transport vehicle, and through the vehicle's own structure, using the lever principle, the weight of the transport vehicle is still borne on the weighbridge body 1, reducing the force on the support roller 333, while ensuring that the device is suitable for various types of transport vehicles.

[0071] In this invention, the support column 122 is inserted into the support groove 11 by the push of the electric push rod 123, and then inserted into the support holes 25 at both ends of the support frame 211; ensuring that after the support platform 21 is raised, it can be combined with the weighbridge body 1 to form a whole, which facilitates the load measurement of transport vehicles.

[0072] During the implementation of this technical solution, those skilled in the art need to connect all electrical components in this case to the external power supply mechanism, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and complete the electrical connection by referring to the working sequence of each electrical component. The detailed connection method is a well-known technology in the field. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0073] In specific use of this invention, the staff directs the transport vehicle to move onto the weighbridge platform 1. Based on the actual type of transport vehicle, the staff directs the current transport vehicle to move onto the weighbridge platform 1 by driving forward or backward. By utilizing the different driving methods and based on the actual position of the drive wheels, the staff moves the drive wheels of the transport vehicle onto the weighbridge platform 1 and positions them between the adjustable roller box mechanism 3 and the adjustable support mechanism 2. At the same time, the staff observes the position of the transport vehicle and directs the driver to adjust the drive wheels of the vehicle to the appropriate position.

[0074] Then you can proceed as follows:

[0075] S1: Control the electric push rod 123 to retract, so that it drives the support column 122 to move out of the support hole 25, and at the same time control the support cylinder 26 to extend, so that the support base plate 261 contacts the ground.

[0076] S2: When the support column 122 is fully retracted into the fixed sleeve 121, the support platform 21 is flush with the weighbridge body 1 with the support of the support base plate 261. Then, the support cylinder 26 is extended to push the support platform 21 up to a certain height and align the lower support seat 22 with the weighbridge body 1.

[0077] S3: Control the electric push rod 123 to extend, so that it pushes the support column 122 out of the fixed sleeve 121 and inserts it into the support sleeve 222 on the lower support square tube 221. Then, by using the connection of the support column 122, the lower support seat 22 is connected to the weighbridge body 1. Then, control the support cylinder 26 to retract a certain amount, so that the support base plate 261 is separated from the ground.

[0078] S4: Control the drive motor 323 to work, so that it drives the adjusting screw 32 to rotate. Through the rotation of the synchronous pulley 321 and the synchronous belt 322, the two adjusting screws 32 rotate synchronously. Then, through the threaded connection between the adjusting screw 32 and the sliding adjusting frame 33, it drives the sliding adjusting frame 33 to move inside the square box 31. The sliding adjusting frame 33 pushes the fixed shaft 332 and the support roller 333 to extend out of the square box 31.

[0079] S5: As the fixed shaft 332 and the support roller 333 gradually extend, the center of gravity of the adjustable roller box mechanism 3 gradually changes, and as the center of gravity is adjusted, the square box 31 is gradually adjusted to be horizontal, and one end of it is placed on the weighbridge body 1. Then the fixed shaft 332 and the support roller 333 extend to a suitable length.

[0080] S6: When the fixed shaft 332 and the support roller 333 extend to a certain length, one end of the fixed shaft 332 moves to one side of the support platform 21, and as the fixed shaft 332 moves, it gradually inserts into the support shaft hole 242 of the corresponding sliding seat 241, and makes it fully connected with the support shaft hole 242.

[0081] S7: At this time, the drive wheel of the transport vehicle is located between the two support rollers 333 of each group. Then, the control adjustment motor 231 is turned on, and the adjustment motor 231 drives the adjustment screw 23 to rotate. Through the threaded connection between the adjustment screw 23 and the internal thread adjustment sleeve 243, the two sliding seats 241 and the roller seats 331 of each group move closer to the center of the drive wheel at the same time. Through the rotation of the support rollers 333, they squeeze the tires of the drive wheel, thereby lifting the drive wheel and separating it from the weighbridge platform 1.

[0082] S8: At this time, the drive wheels of the transport vehicle are disengaged from the main body 1 of the weighbridge. Simultaneously, due to the extension of the fixed shaft 332 and the support roller 333, the square box 31 is disengaged from the ground. The staff can then control the weighbridge to detect overload of the transport vehicle. In the event of a vehicle escaping, the support roller 333 supports the drive wheels of the transport vehicle, causing the rotation of the drive wheels to be transmitted to the support roller 333, thereby restricting the transport vehicle to the weighbridge platform 1 and preventing its movement, effectively avoiding accidents.

[0083] S9: When the transport vehicle has finished its inspection and needs to leave the weighbridge body 1, the control adjustment motor 231 is rotated in reverse, and then the adjustment screw 23 is connected to the internal thread adjustment sleeve 243 through the thread, so that each set of two sliding seats 241 and roller seats 331 move away from the drive wheels at the same time, so that the drive wheels of the transport vehicle descend and contact the weighbridge body 1, and at the same time the sliding seats 241 and roller seats 331 are reset to their original positions.

[0084] S10: Then control the drive motor 323 to rotate in the opposite direction. By using the reverse rotation of the adjusting screw 32, the sliding adjusting frame 33 drives the fixed shaft 332 and the support roller 333 to gradually retract into the square box 31. Then, by using the center of gravity of the square box 31, it is placed on the ground again.

[0085] S11: After the square box 31 is reset, the support cylinder 26 is extended again and the support platform 21 is supported by the support base plate 261. Then, the electric push rod 123 is retracted, so that the support column 122 is retracted back into the fixed sleeve 121. Then, the support cylinder 26 is retracted, so that the support platform 21 is lowered and flush with the upper surface of the weighbridge body 1. Then, the electric push rod 123 is extended again, so that the support column 122 is inserted into the support hole 25. Finally, the support cylinder 26 is retracted by a certain amount, so that the support base plate 261 is separated from the ground.

[0086] In the specific implementation of this device, in order to facilitate the positioning of the drive wheels of the transport vehicle by the staff, the staff can spray paint on the upper surface of the weighbridge body 1. The spraying position is located on the upper surface of the weighbridge body 1 on both sides of the support groove 11, and the corresponding positions of the two adjacent sets of sliding seats 241 and roller seats 331 are painted with different colors. At the same time, a center mark can be sprayed at the center to facilitate the staff to position the center of the drive wheels of the transport vehicle.

[0087] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
