Description

Technical Field

[0001] This utility model relates to the field of trailer traction arm technology, and in particular to a traction arm for a scrap steel trailer. Background Technology

[0002] In the steel production process, the transportation of scrap steel is crucial. Currently, trailer-swapping trucks, due to their high efficiency and flexibility, are widely used in the scrap steel transportation sector of the steel metallurgical industry. A tractor unit connects to a trailer via a boom to tow the trailer loaded with scrap steel.

[0003] The traditional docking structure design of the drawbar and the towing tailstock of the scrap steel truck bed is not reasonable. The docking process is cumbersome and difficult to position accurately, resulting in low docking efficiency. During towing, due to the large weight of the scrap steel truck bed and the complex road conditions, a large inertial impact force is generated when the vehicle starts and stops. Common drawbars lack effective buffering mechanisms and cannot effectively absorb and mitigate these impact forces. This not only damages the drawbar structure itself and shortens its service life, but may also cause the scrap steel in the truck bed to shift, affecting transportation safety. Therefore, it is necessary to design a drawbar for scrap steel trailers to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a towing arm for scrap steel trailers to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a traction arm for a scrap steel trailer, comprising:

[0007] The scrap steel trailer traction boom is equipped with a traction docking buffer mechanism.

[0008] The traction docking buffer mechanism includes an abutment block, a scrap steel truck bed traction tail seat, an adapter frame, and a docking slot.

[0009] The abutment block is fixedly installed on the traction boom of the scrap steel trailer, and the adapter frame is fixedly installed on the side of the traction tail seat of the scrap steel truck bed. The abutment block abuts against the adapter frame, and a docking groove is provided on the side of the traction tail seat of the scrap steel truck bed. The traction boom of the scrap steel trailer is engaged with the docking groove.

[0010] A further feature of this invention is that the traction docking buffer mechanism includes a connecting frame, a side frame, a hydraulic cylinder, a moving frame, a square plate, a damper, and a buffer spring. The connecting frame is fixedly installed on the top of the adapter frame, the side frame is fixedly installed on the traction boom of the scrap steel trailer, the hydraulic cylinder is fixedly installed on the top of the side frame, the hydraulic rod of the hydraulic cylinder is fixedly connected to the moving frame, and the damper and the buffer spring are both fixedly installed between the square plate and the moving frame.

[0011] A further feature of this invention is that an mounting bracket is fixedly installed on the traction boom of the scrap steel trailer.

[0012] By adopting the above technical solution, the mounting bracket is installed on the hydraulic equipment of the trailer.

[0013] A further feature of this invention is that a rubber pad is fixedly installed at the bottom of the scrap steel truck bed traction tail seat.

[0014] A further feature of this invention is that a limiting frame is fixedly provided on the side of the square plate, and the limiting frame is slidably mounted on the movable frame.

[0015] By adopting the above technical solution, the limiting frame can move stably in the lateral direction.

[0016] A further feature of this invention is that a limiting hole is provided on the side of the movable frame, and the limiting frame is slidably installed in the limiting hole, with the limiting frame in contact with the side of the movable frame.

[0017] By adopting the above technical solution, the limiting frame can move stably in the lateral direction.

[0018] A further feature of this invention is that the connecting frame is located below the square plate.

[0019] A further feature of this invention is that a movable hole is provided on the top of the side frame, and the movable frame is vertically slidably installed in the movable hole.

[0020] The beneficial effects of this utility model are:

[0021] This utility model, through its traction docking buffer mechanism, features an inclined design at the bottom of the docking slot of the scrap steel truck bed's traction tail seat, which guides the scrap steel trailer's traction arm to quickly insert, reducing the time spent on repeated manual adjustments. Simultaneously, the tight contact between the abutment block and the adapter frame, along with the locking structure between the traction arm and the docking slot, creates multiple positioning mechanisms, preventing loosening due to vibration during transportation, ensuring structural stability after docking, and reducing safety hazards. The buffer spring and damper in the traction docking buffer mechanism work together to effectively absorb the inertial impact force during vehicle start-up and stop. When the scrap steel truck bed moves due to inertia, the connecting frame presses against the square plate, the buffer spring initially offsets the impact force through elastic deformation, and the damper suppresses spring rebound oscillation, significantly reducing damage to the traction arm and truck bed connection structure, extending equipment lifespan, and reducing scrap steel displacement within the truck bed, thus ensuring transportation safety.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a towing arm for a scrap steel trailer, comprising:

[0031] The scrap steel trailer traction boom 1 is equipped with a traction docking buffer mechanism. It should be noted that this facilitates docking with the scrap steel truck bed traction tail seat 4, ensuring stability after docking. In addition, it can play a good buffering role during the traction process.

[0032] The traction docking buffer mechanism includes abutment block 3, scrap steel truck bed traction tail seat 4, adapter frame 5 and docking groove 6;

[0033] The abutment block 3 is fixedly installed on the traction boom 1 of the scrap steel trailer, and the adapter 5 is fixedly installed on the side of the traction tail seat 4 of the scrap steel truck bed. It should be noted that the traction tail seat 4 of the scrap steel truck bed is installed at the rear of the scrap steel truck bed. The front side of the scrap steel truck bed is equipped with a movable wheel, and the rear side contacts the ground through the rubber pad 15.

[0034] The abutting block 3 abuts against the adapter frame 5. The side of the scrap steel truck bed traction tail seat 4 is provided with a docking groove 6. The scrap steel trailer traction boom 1 is engaged with the docking groove 6. It should be noted that the bottom of the docking groove 6 is inclined to facilitate the docking guidance between the scrap steel trailer traction boom 1 and the docking groove 6. Moreover, the size of the docking groove 6 is larger than the size of the scrap steel trailer traction boom 1.

[0035] With the above structure, the trailer reversing inserts the scrap steel trailer traction boom 1 into the docking slot 6. At this time, there is a certain gap between the scrap steel trailer traction boom 1 and the docking slot 6. Then, the hydraulic rotating lifting device on the trailer rotates and lifts the scrap steel trailer traction boom 1. When the scrap steel trailer traction boom 1 touches the inner wall above the docking slot 6, it will drive the scrap steel truck bed traction tail seat 4 to move, so that the rubber pad 15 separates from the ground and the abutment block 3 contacts the adapter frame 5. Then, the vehicle reversing is used to pull the scrap steel truck bed traction tail seat 4.

[0036] Specifically, the traction docking buffer mechanism also includes a connecting frame 7, a side frame 8, a hydraulic cylinder 9, a moving frame 10, a square plate 11, a damper 13, and a buffer spring 14. The connecting frame 7 is fixedly installed on the top of the adapter frame 5, the side frame 8 is fixedly installed on the scrap steel trailer traction boom 1, the hydraulic cylinder 9 is fixedly installed on the top of the side frame 8, the hydraulic rod of the hydraulic cylinder 9 is fixedly connected to the moving frame 10, and the damper 13 and the buffer spring 14 are both fixedly installed between the square plate 11 and the moving frame 10.

[0037] With the above structure, after lifting the scrap steel truck bed traction tail seat 4, the hydraulic cylinder 9 is activated, causing the moving frame 10 and the square plate 11 to move down, so that the side of the square plate 11 contacts the connecting frame 7. During the reversing process of the trailer, when the trailer stops, the scrap steel truck bed traction tail seat 4 will continue to move backward due to inertia. At this time, the connecting frame 7 will squeeze the square plate 11, causing the square plate 11 to squeeze the buffer spring 14. Through the action of the buffer spring 14 and the damper 13, the scrap steel truck bed traction tail seat 4 can be well buffered and protected. After the scrap steel truck bed traction tail seat 4 is in the designated position, it can be lowered down.

[0038] Specifically, a mounting frame 2 is fixedly installed on the traction boom 1 of the scrap steel trailer. It should be noted that the traction boom 1 of the scrap steel trailer is fixedly connected to the hydraulic rotary lifting equipment on the trailer through the mounting frame 2, so that the traction boom 1 of the scrap steel trailer can be rotated and lowered by the hydraulic equipment.

[0039] Specifically, a rubber pad 15 is fixedly installed at the bottom of the scrap steel truck bed towing tail seat 4. It should be noted that when the scrap steel truck bed towing tail seat 4 is lowered, the rubber pad 15 contacts the ground to protect the scrap steel truck bed towing tail seat 4.

[0040] Specifically, a limiting frame 12 is fixedly installed on the side of the square plate 11. The limiting frame 12 is slidably installed on the movable frame 10. A limiting hole is opened on the side of the movable frame 10. The limiting frame 12 is slidably installed in the limiting hole and contacts the side of the movable frame 10. It should be noted that this allows the square plate 11 to move stably in the lateral direction.

[0041] Specifically, the connecting frame 7 is located below the square plate 11, and the top of the side frame 8 has a moving hole. The moving frame 10 is vertically slidably installed in the moving hole. It should be noted that this allows the moving frame 10 to move stably in the vertical direction.

[0042] Working principle:

[0043] S1: The docking of the scrap steel trailer's traction boom 1 and the scrap steel truck bed's traction tailstock 4 is achieved through precise structural fit. When the trailer is reversing, the traction boom 1 is aligned with the docking groove 6 on the side of the scrap steel truck bed's traction tailstock 4. Because the bottom of the docking groove 6 is inclined, it guides the traction boom, allowing it to smoothly insert into the groove. At this point, the hydraulic rotating lifting device on the trailer connects to the mounting bracket 2 on the traction boom, causing it to rotate and lift. After the traction boom touches the upper inner wall of the docking groove 6, it simultaneously lifts the scrap steel truck bed's traction tailstock 4, separating the rubber pad 15 at the bottom of the traction tailstock 4 from the ground. Simultaneously, the abutment block 3 on the traction boom and the adapter bracket 5 on the scrap steel truck bed's traction tailstock 4 abut tightly, completing the mechanical docking and providing a stable force base for subsequent traction.

[0044] S2: During the traction process, the buffer mechanism offsets the inertial impact force through the dual action of elasticity and damping. After docking, the hydraulic cylinder 9 on the side frame 8 is activated. Its hydraulic rod pushes the moving frame 10 to move vertically downward along the moving hole of the side frame 8 until the square plate 11 contacts the connecting frame 7 at the top of the adapter frame 5. When the trailer brakes or decelerates, the scrap steel truck bed continues to move forward due to inertia. The connecting frame 7 will squeeze the square plate 11. The square plate 11 drives the limiting frame 12 to slide laterally along the limiting hole of the moving frame 10, while squeezing the buffer spring 14 and the damper 13. The buffer spring 14 absorbs part of the impact force through elastic deformation, while the damper 13 slows down the rebound speed of the spring through damping, avoiding violent oscillation. The double buffer effectively protects the traction structure and the scrap steel truck bed, reducing impact damage.

[0045] S3: Upon arrival at the designated location, the hydraulic equipment is reversed to lower the height of the traction boom, causing the scrap steel truck bed traction tail seat 4 to fall until the bottom rubber pad 15 contacts the ground. The rubber pad 15 cushions the impact of the fall and prevents the truck bed from directly colliding with the ground. Subsequently, the hydraulic cylinder 9 is activated in reverse to separate the square plate 11 from the connecting frame 7, allowing the trailer to move forward. The traction boom is then pulled out of the docking slot 6, completing the entire traction process. Throughout the entire operation, the traction docking mechanism ensures a stable connection, the buffer mechanism reduces inertial impact, and the rubber pad 15 protects the placement process. The three work together to achieve safe and stable traction and transportation of the scrap steel truck bed.
