Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an L-shaped trolley for winding and unloading. Background Technology

[0002] In the processing of metal coils, slitting is a crucial pre-processing step, where wide metal coils are cut into multiple narrow coils of varying widths using slitting equipment. The slitting coils then need to be transferred from the slitting machine's winding mechanism to subsequent processing stations such as leveling and stamping. The equipment used in this short-distance transfer directly impacts the continuity and efficiency of production.

[0003] Currently, most metal coil transfer equipment on the market consists of ordinary flatbed trolleys or simple lifting devices. These devices have significant technical defects: First, they have poor adaptability. After slitting, the coils naturally have gaps and vary in width. The integrated pressure plate fixing mechanism of traditional equipment cannot independently fix a single coil, which can easily lead to some coils becoming loose or excessively squeezed and deformed. Second, they lack stability. Relying solely on the weight of the coil for positioning, they are prone to rolling deviation when the equipment starts, stops, or turns, which may cause scratches on the surface or damage to the edges of the coil. Third, they are cumbersome to operate. The fixing mechanism needs to be frequently adjusted for coils with different gaps or widths, increasing manual labor intensity and reducing production cycle time.

[0004] For example, Chinese utility model patent CN202421057540.9 discloses a roll material transfer vehicle, which uses an integral arc-shaped pallet to carry the roll material and fixes it by pushing clamps with cylinders on both sides. This structure cannot adapt to roll materials that are spaced apart after slitting, and the fixing force is difficult to adjust, easily causing damage to the roll material. Therefore, developing a transfer device that can adapt to the differences in the spacing and width of the slitting roll material, provide stable fixing, and is easy to operate is an urgent need in this field.

[0005] Therefore, it is of great significance to provide a winding and unloading L-shaped trolley to solve the problems existing in the current technology. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a winding and unloading L-shaped trolley to solve the problem.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0018] Preferably, a hydraulic rod is also vertically installed on one side of the vertical lifting frame. The telescopic end of the hydraulic rod is fixedly connected to the sliding seat and is used to drive it to rise and fall along the lateral slide rail.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1.

[0038] Please see Figure 1-6 This utility model provides a technical solution for an L-shaped trolley for winding and unloading:

[0039] The L-shaped winding and unloading trolley consists of the following six core parts, the structure and function of each part are as follows:

[0040] Moving tracks: Two parallel tracks are laid on the ground to provide directional movement for the trolley. They are made of high-strength steel to ensure load-bearing stability. The track spacing is precisely matched to the wheelbase of the moving frame to prevent the trolley from deviating during movement.

[0041] Mobile Track 1: Two parallel tracks laid on the ground provide a directional movement path for the trolley. Made of high-strength steel, they ensure load-bearing stability. The track spacing precisely matches the wheelbase of the mobile frame to prevent the trolley from deviating during movement.

[0042] Mobile frame 3: Serving as the main support frame of the equipment, it has two symmetrically mounted traveling wheels 2 and two drive wheels 16 at its bottom. The traveling wheels are located at the front end of the frame, and the drive wheels are located at the rear end, both fitting onto the mobile track 1. A drive mechanism is integrated on one side of the frame. This mechanism consists of a drive motor 13, a reduction gearbox 15, and a transmission shaft 17. The output end of the drive motor is connected to the reduction gearbox via a coupling, and the output end of the reduction gearbox is synchronously driven by the two drive wheels via the transmission shaft, enabling the trolley to move automatically in the forward or reverse direction along the track.

[0043] The vertical lifting frame 6 has a "gate"-shaped frame structure and is fixed to the rear top of the mobile frame 3 with high-strength bolts. Symmetrical vertical grooves are provided on its inner side to guide the lifting and lowering motion. Two parallel lateral slide rails 9 are also fixed to the front of the lifting frame, with sliding seats 8 slidably fitted on them. A hydraulic rod 7 is vertically installed at the top of the lifting frame, with its telescopic end fixedly connected to the top of the sliding seat, allowing the sliding seat to be stably raised and lowered along the lateral slide rails.

[0044] L-shaped lifting frame 4: It is integrally welded from a horizontal bearing section and a vertical connecting section. Lifting pulleys 18 are symmetrically installed on both sides of the vertical connecting section. The lifting pulleys are fitted with the vertical groove of the vertical lifting frame 6 to ensure smooth lifting without jamming. A hydraulic rod 14 is vertically installed at the bottom inside the vertical lifting frame. Its telescopic end is fixed to the bottom of the vertical connecting section of the L-shaped lifting frame via a flange. When the hydraulic rod 14 extends or retracts, it can drive the L-shaped lifting frame to rise and fall along the vertical groove as a whole.

[0045] V-shaped load-bearing plate 5: Forged from wear-resistant steel plate, it is bolted to the top of the horizontal load-bearing section of the L-shaped lifting frame 4. Its V-groove angle is set at 75°-85°, allowing for automatic centering of the metal coil using gravity, preventing lateral slippage. The surface of the load-bearing plate has anti-slip textures, further enhancing the stability of the coil placement.

[0046] The pressing mechanism 12 is fixed to the bottom of the sliding seat 8 via the connecting arm 10 and the connecting block 11, and is suspended directly above the V-shaped load plate 5. This mechanism includes a rectangular shell 122 with a closed top, multiple independent pressing blocks 124, a compression spring 121, and a limiting rod 125. The number of pressing blocks matches the number of common slitting rolls, which is 3-6. The top of each pressing block is elastically connected to the top wall of the shell via a spring, and a waist hole 123 is opened in the middle. A limiting rod fixed horizontally inside the shell passes through the waist hole, which not only restricts the vertical movement of the pressing blocks, but also ensures that the pressing blocks can only extend and retract vertically, so as to achieve independent elastic pressing of each pressing block.

[0047] This equipment achieves fully automated positioning, fixing, and transfer of slit metal coils through the coordinated operation of mechanical structure, hydraulic system, and electric motor drive. The core working principle is as follows, with corresponding diagram labels for each structure:

[0048] First, in the initial state of the equipment, the L-shaped lifting frame 4 is in a low position and the pressing mechanism 12 is in a high position. According to the output height requirements of the slitting machine, the control system activates the hydraulic rod 14. The telescopic end of the hydraulic rod 14 extends and pushes the L-shaped lifting frame to rise along the slide of the vertical lifting frame 6 until the top surface of the V-shaped load plate 5 is flush with the output port of the slitting machine. The hydraulic rod 14 then stops moving and locks, completing the height pre-adjustment.

[0049] After being slit, the metal coils roll sequentially into the V-groove of the V-shaped load plate 5 via the slitting machine's discharge mechanism. The V-shaped structure automatically centers and positions itself using the weight of the coil. Subsequently, the control system activates hydraulic rod 7, whose telescopic end extends to drive the sliding seat 8 down along the lateral slide rail 9. The pressing mechanism 12 moves down accordingly. When the bottom of each pressing block 124 contacts the top of the corresponding coil, the sliding seat continues to descend slightly. The compression spring 121 is compressed and generates elastic force, causing each pressing block to independently press the corresponding coil under the action of elastic force. The limiting rod 125 limits the maximum compression of the pressing block through the waist hole 123 to avoid excessive compression and damage to the coil. At this time, the coil is doubly fixed by "lower positioning + upper pressing".

[0050] After the roll material is fixed, the drive motor 13 starts, and the power is reduced and increased in torque by the reduction gearbox 15, and then drives the drive wheel 16 to rotate along the moving track 1 through the transmission shaft 17. The traveling wheels 2 follow and guide, and the trolley carrying the roll material moves smoothly to the target workstation storage rack or the next process at a set speed of 0.3-0.5 m / s. After reaching the target position, the drive motor stops and the drive wheels are locked to prevent the trolley from moving.

[0051] During unloading, firstly, hydraulic rod 7 retracts, causing the pressing mechanism 12 to rise and detach from the roll material, releasing the clamping force. Then, hydraulic rod 14 adjusts the height of the L-shaped lifting frame 4 so that the V-shaped load-bearing plate 5 is flush with the bearing surface of the target station. Finally, the roll material is pushed from the V-shaped load-bearing plate to the target position manually or by an auxiliary pushing mechanism to complete the unloading. After unloading, hydraulic rod 2 drives the L-shaped lifting frame to reset, the drive motor 13 rotates in the opposite direction, and the trolley returns to the slitting machine along the track, ready for the next round of transfer.

[0052] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
