Description

Technical Field

[0001] This utility model belongs to the field of vehicle transportation technology, specifically relating to a movable overhanging plate for a car carrier. Background Technology

[0002] In the field of car carrier design and manufacturing, the movable deck is a core functional component of loading and unloading vehicles, and its performance directly determines the overall operating efficiency and safety of the vehicle. Traditional movable decks typically use a simple mechanical structure with pins or bolts for angle adjustment and position locking. This type of structure reveals significant drawbacks in practical applications: First, the manual unlocking and locking process is extremely cumbersome, requiring operators to repeatedly bend over to operate the fasteners, which is not only time-consuming and labor-intensive but also poses safety hazards in confined working spaces. Second, when adjusting the angle or moving the deck forward or backward, the lack of effective drag reduction design often leads to excessive friction on the metal contact surface, causing movement stagnation and forcing operators to rely excessively on the hydraulic system's thrust, accelerating component wear. More importantly, traditional locking mechanisms rely on manual visual alignment and manual reinforcement, which can easily lead to accidental deck displacement during loading or transportation due to insufficient locking force or minor positioning deviations. This can affect loading and unloading accuracy or even cause vehicle slippage accidents.

[0003] With the development of larger and more efficient car carriers, the market has placed higher demands on the ease of operation, smoothness of movement, and locking reliability of the tilting plate system. While existing technologies have attempted to improve this by using hydraulic locks or electronic positioning devices, the former is structurally complex and has high maintenance costs, while the latter lacks stability under harsh conditions such as vibration and oil contamination. Therefore, the industry urgently needs an integrated locking solution that combines a simple mechanical structure, low resistance during adjustment, and reliable self-resetting locking capability to fundamentally solve the stability problem of the tilting plate system under dynamic loads, while simultaneously improving the ergonomics and safety redundancy of loading and unloading operations. Utility Model Content

[0004] The purpose of this utility model is to provide a movable overhanging plate for a car carrier, which aims to solve the problems mentioned in the background art.

[0005] A movable overhang for a car carrier includes,

[0006] Workbench;

[0007] A locking assembly is located on the outer wall of the worktable, comprising: a tilting plate body, a protective shell, a mounting shaft, a constraint frame, a rotating locking tooth, a torsion spring, a rack, and a drive assembly. The tilting plate body is slidably embedded in a slot in the inner wall of the worktable. The protective shell is fitted onto both sides of the outer wall of the worktable. The mounting shaft is fixedly located on the outer wall of the tilting plate body. The constraint frame is fitted onto the outer wall of the mounting shaft. The rotating locking tooth is rotatably embedded in the inner wall of the constraint frame. The two ends of the torsion spring are respectively engaged with the outer wall of the rotating locking tooth. The rack is embedded in the inner wall of the protective shell. The rotating locking tooth and the rack are meshed together. The drive assembly is located on the outer wall of the worktable.

[0008] Furthermore, the drive assembly includes a mounting frame, a hydraulic rod, and a rotating seat. The mounting frame is fixedly disposed at the bottom of the outer wall of the workbench. One end of the hydraulic rod is rotatably sleeved on the outer wall of the mounting frame. The output end of the hydraulic rod is fixedly disposed on the inner wall of one end of the rotating seat. The rotating seat is rotatably inserted into the protruding end of the outer wall of the tilting plate body.

[0009] Furthermore, an installation groove is provided on the top of the outer wall of the main body of the tilting plate.

[0010] Furthermore, limiting grooves are provided on both sides of the top of the outer wall of the workbench, and drag-reducing wheels are rotatably sleeved on the protruding ring of the outer wall of the main body of the tilting plate.

[0011] Furthermore, the drag-reducing wheel is rotatably embedded in the inner wall of the limiting groove.

[0012] Furthermore, a crank handle is inserted into the outer wall of the rotating tooth.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This locking assembly, through its ingenious structural design, effectively enhances the ease of operation and stability of the movable tilting plate of a car carrier. Its core lies in the reliable locking of the tilting plate's rotation axis through the engagement of rotating teeth and a fixed rack. When adjusting the tilting plate's angle or position, the operator simply uses a rocker arm to temporarily disengage the rotating teeth from the rack. Driven by a hydraulic rod, the tilting plate moves smoothly within the worktable's limiting groove using drag-reducing wheels, easily changing its tilt angle or forward / backward position. Once adjusted, releasing the rocker arm causes the rotating teeth to automatically reset and re-engage with the rack under the action of a torsion spring, forming a stable mechanical lock. This design significantly reduces operational resistance when adjusting the tilting plate while ensuring absolute stability of the tilting plate's position during operation, preventing accidental movement and greatly improving the safety and efficiency of vehicle loading and securing. The overall structure is compact, and the operation is intuitive and simple. Attached Figure Description

[0028] In a specific embodiment of this utility model, the locking component first deploys the workbench 1 onto the vehicle chassis. A wheel locking device is arranged inside the mounting groove 201. When the vehicle is driven directly above the main body 2 of the tilting plate, the handbrake and wheels of the vehicle are locked. The hydraulic rod 5 is activated, and the tilting plate 2 is rotated by the rotating seat 202. When the tilting plate 2 needs to be moved further to shorten the distance, the rocker arm is pressed, causing the two rotating teeth 8 to disengage from the engagement. The hydraulic rod 5 is then activated again, causing the tilting plate 2 to move inside the limiting groove 101 through the drag-reducing wheel 4, shortening the distance and placement angle of the tilting plate 2. The crank handle 801 is released, causing the rotating teeth 8 to continuously engage with the rack 10, thus completing the stable locking of the rotation axis of the tilting plate 2.

[0029] Specifically, the drive assembly includes a mounting bracket 102, a hydraulic rod 5, and a rotating seat 202. The mounting bracket 102 is fixedly installed at the bottom of the outer wall of the workbench 1. One end of the hydraulic rod 5 is rotatably sleeved on the outer wall of the mounting bracket 102.

The rotating seat 202 is rotatably inserted into the protruding end of the outer wall of the tilting plate body 2.

[0030] In a specific embodiment of this utility model, the rotating seat 202 is rotatably inserted into the protruding end of the outer wall of the upright plate body 2, which can reduce the driving resistance.

[0031] Specifically, an installation groove 201 is provided on the top of the outer wall of the main body 2 of the upright plate.

[0033] Specifically, the top two sides of the outer wall of the workbench 1 are provided with limiting grooves 101, and the outer wall of the main body of the overhead plate 2 is fitted with a drag-reducing wheel 4.

[0034] In a specific embodiment of this utility model, a drag-reducing wheel 4 is rotatably sleeved on the outer wall protrusion ring of the tilting plate body 2, which can reduce the running resistance of the tilting plate body 2.

[0039] Working principle:

[0040] First, the moving table 1 is deployed to the designated working position. Quartz stone and adhesive are continuously supplied to the material feeding pipe 9 through the pipeline. The moving frame 8 is driven by the drive motor 10 to reciprocate, which further drives the material feeding pipe 9 to continuously and stably supply quartz stone and adhesive, so that the quartz stone and adhesive initially fall onto the inner wall of the molding mold 4. At this time, the drive slider 13 moves, so that the extrusion plate 14 is close to the molding mold 4. The working angle of the rotating plate 16 is adjusted by the angle motor 15. Then, the extrusion roller 17 is used to initially crush the quartz stone and adhesive to ensure compactness. Then, the quartz stone and adhesive are supplied again for crushing until the thickness of the quartz stone and adhesive reaches the standard. Finally, the moving plate 12 is moved on the constraint table 11 so that the flat plate 1201 is directly above the molding mold 4. At this time, the flat cylinder 1202 is activated to drive the flat plate 1201 to descend, completing the re-extrusion of the quartz stone and adhesive to ensure the flatness of the molded product.
