Description

Technical Field

[0001] This utility model belongs to the field of trailer manufacturing and processing technology, and more specifically, it relates to a finished product traction and conveying device for trailer processing. Background Technology

[0002] A trailer is a road transport vehicle towed by a car and without its own power drive. In the trailer manufacturing process, after all processing steps are completed, the finished trailer needs to be transferred from the production station to the storage area or transported to the subsequent assembly station for further assembly. Existing finished trailer conveying systems primarily use motor-driven roller conveyors to automate the transport of finished trailers.

[0003] The existing application number CN202020109659.1 relates to the field of trailer manufacturing technology, and in particular to a conveying device for trailer manufacturing. It includes a support plate and a fixed plate, the support plate and the fixed plate being slidably connected. A first handle is rotatably connected to the bottom surface of the support plate, the first handle passing through the support plate. A connecting rod is fixedly connected to the other end of the first handle, and the connecting rod is rotatably connected to the support plate. In this invention, through the provided second handle, second threaded shaft, first clamping plate, and second clamping plate, during the conveying process, rotating the second handle drives the second threaded shaft to rotate. The second threaded shaft drives the third threaded shaft to rotate through the fixed shaft, thereby driving the second slider to slide. The second slider drives the first clamping plate and the second clamping plate to move. This can limit the movement of raw materials during the conveying process, preventing the raw materials from sliding, colliding, or falling on the conveying device, and thus not affecting the conveying efficiency of the device.

[0004] Based on the above, existing finished product conveying devices for trailer processing, in actual conveying operations, are significantly affected by factors such as rolling deviation and equipment vibration caused by the operation of the roller conveyor, which can easily lead to positional deviations of the finished products placed on it. When conveying long or heavy finished products, the friction between the roller conveyor and the finished product contact surface is prone to imbalance, causing jams and stagnation in the conveying process. The uneven weight distribution of the finished products themselves further amplifies the deviations caused by equipment vibration. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a finished product traction and conveying device for trailer processing. This addresses the issues of existing finished product conveying devices for trailer processing, where rolling deviations and equipment vibrations generated during actual conveying operations significantly impact the finished trailers placed on them, easily leading to positional deviations along the conveying path. When conveying long or heavy finished trailers, the friction between the roller conveyor and the finished product contact surface is prone to imbalance, causing jams and stoppages during conveying. Furthermore, the uneven weight distribution of the finished product further amplifies the deviations caused by equipment vibrations.

[0006] The purpose and function of this utility model for a finished product traction and conveying device for trailer processing are achieved by the following specific technical means: A finished product traction and conveying device for trailer processing includes a conveying mechanism, a support frame, a hoist trolley, a drive mechanism, hydraulic rods, a towing hook, an anti-detachment component, and an unlocking component. The support frame is fixedly installed on the upper part of the conveying mechanism; the hoist trolley is slidably connected to the upper part of the support frame; the drive mechanism is fixedly installed at the bottom of the hoist trolley; two sets of hydraulic rods are provided, and the two sets of hydraulic rods are slidably connected to each other at the bottom of the drive mechanism; two sets of towing hooks are provided, and the two sets of towing hooks are fixedly installed at the bottom of the two sets of hydraulic rods; the anti-detachment component is disposed inside the towing hook; and the unlocking component is disposed inside the towing hook.

[0007] Furthermore, the anti-detachment component includes: a first opening, an internal hook, and a second opening. The first opening is provided in two sets, with each set of the first opening being opened inside the two sets of traction hooks. The internal hook is provided in two sets, with each set of the internal hooks being vertically slidably connected inside the two sets of traction hooks. The second opening is provided in two sets, with each set of the second opening being opened inside the two sets of internal hooks.

[0008] Furthermore, the anti-detachment component also includes: guide grooves and limiting blocks. Two sets of guide grooves are provided, and the two sets of guide grooves are opened inside the two sets of internal hooks. Two sets of limiting blocks are provided, and the two sets of limiting blocks are slidably connected inside the two sets of guide grooves respectively.

[0009] Furthermore, the anti-detachment component also includes: a first spring and a second spring. The first spring is provided in two sets, with each set of the first spring fixedly installed in the middle position between the traction hook and the inner hook body; the second spring is provided in two sets, with the two sets of the second spring fixedly installed in the middle position between the guide slide and the limiting block.

[0010] Furthermore, the anti-detachment component also includes a limiting groove, wherein two sets of limiting grooves are provided, and the two sets of limiting grooves are respectively opened inside the two sets of traction hooks.

[0011] Furthermore, the unlocking component includes: a guide rod and a trigger plate. The guide rod is provided in two sets, and the two sets of guide rods are slidably connected to the top of the inner side of the traction hook. The trigger plate is provided in two sets, and the two sets of trigger plates are fixedly installed at the ends of the two sets of guide rods.

[0012] Furthermore, the unlocking assembly also includes: a third spring, a trigger switch, and an electromagnet. The third spring is provided in two sets, with each set of the third spring fixedly connected to the middle position between the inner hook body and the trigger plate. The trigger switch is provided in two sets, with the two sets of trigger switches fixedly installed on the top inner side of the two sets of inner hook bodies. The electromagnet is provided in two sets, with the two sets of electromagnets respectively fixedly installed inside the two sets of guide grooves. The electromagnets and trigger switches form a switching circuit through a wiring harness and a power supply.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this utility model has an anti-detachment component, which aligns the towing hook with the opening of the internal hook body under normal conditions, facilitating smooth engagement with the trailer frame. During towing, the internal hook body is pulled down by the gravity of the trailer frame, causing the opening to close in a misaligned manner. At the same time, the limiting block is engaged with the limiting groove under the action of the spring to form a secondary lock, effectively avoiding the problem of detachment caused by vibration and offset during transportation, and solving the defect of poor transportation stability of existing devices.

[0014] Secondly, this utility model has an unlocking component. When the trailer is lowered, the trigger plate is pushed, the spring is compressed and the switch is triggered, so that the electromagnet is energized to attract the limit block and unlock it. Then, with the spring resetting, the internal hook body moves up to reconnect the opening, so that the towing hook can be easily disengaged from the trailer without manual unlocking, improving the operation efficiency and avoiding the safety hazards caused by manual intervention.

[0015] This utility model has the advantages of traction and anti-detachment, convenient use, and quick unlocking. With the help of adjustable hydraulic rods and sliding hoist trolleys, it can be adapted to trailers of different specifications. At the same time, the combination of conveying mechanism and suspension traction avoids the jamming and stagnation problems caused by friction imbalance in traditional roller conveyors, ensuring a smooth and accurate conveying process and effectively improving the safety and efficiency of trailer conveying.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 7 As shown: This utility model provides a finished product traction and conveying device for trailer processing, including a conveying mechanism 1, a support frame 2, a hoist trolley 3, a drive mechanism 4, hydraulic rods 5, a traction hook 6, and an anti-detachment component. The support frame 2 is fixedly installed on the upper part of the conveying mechanism 1; the hoist trolley 3 is slidably connected to the upper part of the support frame 2; the drive mechanism 4 is fixedly installed on the bottom of the hoist trolley 3; two sets of hydraulic rods 5 are provided, and the two sets of hydraulic rods 5 are slidably connected to each other on the bottom of the drive mechanism 4; two sets of traction hooks 6 are provided, and the two sets of traction hooks 6 are fixedly installed on the bottom of the two sets of hydraulic rods 5; the anti-detachment component is located inside the traction hook 6.

[0026] The anti-detachment component includes: a first opening 601, an internal hook 7, and a second opening 701. The first opening 601 is provided in two sets, and the two sets of first openings 601 are respectively opened inside the two sets of traction hooks 6. The internal hook 7 is provided in two sets, and the two sets of internal hooks 7 are respectively vertically slidably connected inside the two sets of traction hooks 6. The second opening 701 is provided in two sets, and the two sets of second openings 701 are respectively opened inside the two sets of internal hooks 7.

[0027] The anti-detachment component also includes: guide slide 702 and limit block 8. There are two sets of guide slide 702, which are opened inside the two sets of internal hooks 7. There are two sets of limit blocks 8, which are slidably connected inside the two sets of guide slide 702 respectively.

[0028] The anti-detachment component also includes: a first spring 603 and a second spring 704. The first spring 603 is provided in two sets, and each set of the first spring 603 is fixedly installed in the middle position between the traction hook 6 and the inner hook body 7. The second spring 704 is provided in two sets, and the two sets of the second spring 704 are fixedly installed in the middle position between the guide slide 702 and the limit block 8.

[0029] The anti-detachment component also includes a limiting groove 602, which is provided in two sets, and the two sets of limiting grooves 602 are respectively opened on the inner side of the two sets of traction hooks 6.

[0030] The specific usage and function of this embodiment are as follows: Under normal conditions, the first spring 603 pushes the inner hook 7 to the top position of the traction hook 6 by its own elastic force. At this time, the first opening 601 of the traction hook 6 is precisely aligned with the second opening 701 of the inner hook 7 and remains connected.

[0031] When trailer transport operations are required, the conveying mechanism 1 is started first to initially transport the finished trailer; then the hoist trolley 3 slides along the support frame 2 to the position directly above the trailer, and the drive mechanism 4 drives the two sets of hydraulic rods 5 to move relative to each other and adjust to the position that matches the trailer suspension structure; then the hydraulic rods 5 extend downwards, and with the help of the connected first opening 601 and second opening 701, the trailer frame is smoothly engaged into the inner hook body 7.

[0032] After the engagement is completed, the hydraulic rod 5 rises upward, causing the trailer frame to move upward synchronously. This is then driven by the hoist trolley 3 to achieve suspension traction. During this process, the weight of the trailer frame pulls the internal hook 7 downward, causing it to move down along the inner wall of the traction hook 6 and compress the first spring 603. At this time, the first opening 601 and the second opening 701 are misaligned, and the openings automatically close, effectively preventing the trailer from becoming unhooked during traction.

[0033] Simultaneously, as the inner hook 7 moves downward, it causes the limiting block 8 to move synchronously. Because the limiting block 8 uses a triangular inclined plane structure, it is compressed by the inner wall of the towing hook 6 during movement. Under this compressive force, the limiting block 8 slides inward along the guide groove 702 and compresses the second spring 704. When the limiting block 8 moves to the corresponding position in the limiting groove 602, the compressive force disappears, the second spring 704 resets, and pushes the limiting block 8 into the limiting groove 602, forming a stable limit. This structure prevents the closure state of the first opening 601 and the second opening 701 from being affected by vibrations during trailer towing, further improving towing safety and stability.

[0034] Example 2: Based on Example 1, as follows Figures 1 to 7 As shown, it also includes an unlocking component, which is located inside the tow hook 6.

[0035] The unlocking component includes: a guide rod 706 and a trigger plate 705. Two sets of guide rods 706 are provided, and the two sets of guide rods 706 are slidably connected to the top of the inner side of the traction hook 6. Two sets of trigger plates 705 are provided, and the two sets of trigger plates 705 are fixedly installed at the ends of the two sets of guide rods 706.

[0036] The unlocking assembly also includes: a third spring 707, a trigger switch 708, and an electromagnet 703. Two sets of third springs 707 are provided, with each set of third springs 707 fixedly connected between the inner hook body 7 and the trigger plate 705. Two sets of trigger switches 708 are provided, with the two sets of trigger switches 708 fixedly installed on the top inner side of the two sets of inner hook bodies 7. Two sets of electromagnets 703 are provided, with the two sets of electromagnets 703 respectively fixedly installed inside the two sets of guide grooves 702. The electromagnets 703 and the trigger switches 708 form a switching circuit through a wiring harness and a power supply.

[0037] The specific usage and function of this embodiment are as follows: When the hoist trolley 3 moves the towing hook 6 and the suspended trailer to the preset placement position, the hydraulic rod 5 extends downward, gradually lowering the trailer to the designated position. At this time, the downward pull of the trailer frame on the internal hook 7 disappears, but the upper part of the trailer frame will simultaneously push the trigger plate 705 at the top of the internal hook 7.

[0038] When the trigger plate 705 is subjected to pushing pressure, it compresses the third spring 707 between itself and the inner hook 7, and moves towards the trigger switch 708. During this process, the guide rod 706 slides along the top of the inner side of the traction hook 6, providing stable guidance for the movement of the trigger plate 705 and preventing deviation. When the trigger plate 705 moves to contact and press the trigger switch 708, the trigger switch 708 is activated, thereby turning on the switching circuit where the electromagnet 703 is located and energizing the electromagnet 703.

[0039] When the electromagnet 703 is energized, it generates a magnetic force, which attracts the limiting block 8 within the guide groove 702. Under the action of the magnetic force, the limiting block 8 slides towards the electromagnet 703 and eventually retracts into the guide groove 702, thus releasing the limiting lock on the internal hook 7. At this time, the internal hook 7 can move upward under the restoring force of the first spring 603, so that the first opening 601 and the second opening 701 are realigned and connected, facilitating the subsequent detachment of the tow hook 6 from the trailer frame and completing the precise placement of the trailer.

[0040] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0041] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

[0042] The above are merely specific implementations of this embodiment, but the protection scope of this embodiment is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment. Therefore, the protection scope of this embodiment should be determined by the protection scope of the claims.
