Description

Technical Field

[0001] This utility model relates to the field of brick production technology, specifically a stacking device for shale brick production and processing. Background Technology

[0002] In the block production line, the formed bricks are typically carried on pallets, with multiple bricks stacked in a fixed array on each pallet. When the bricks are processed into finished products and ready for warehousing, a "brick-pallet separation" process must be completed first, separating the bricks from the pallets. The bricks are then neatly stacked, with forklift holes provided for subsequent forklift transport. This series of processes not only enables the reuse of pallets but also facilitates the packaging and shipping of the bricks before sale.

[0003] However, traditional methods have obvious limitations: if a rigid gripping solution using mechanical claws is adopted, the gripping force adjustment precision of the mechanical claws is low, and there may be slight unevenness or residual dust on the surface of the bricks after curing, which can easily lead to uneven force when the mechanical claws come into contact with the bricks. This can cause minor damage such as chipping or scratching of the brick edges and surfaces, or even cause the bricks to shatter directly.

[0004] If manual operation is adopted for brick separation and stacking, more complex problems arise: First, manually separating bricks requires peeling them one by one from the pallet and then manually stacking them, which is far less efficient than mechanical operation. Especially when the production line is operating at full capacity, manual operation can easily become a bottleneck in production. Second, due to factors such as workers' operating habits and fluctuations in physical strength, the stacked bricks often exhibit problems such as tilting and misalignment between layers. This not only affects the space utilization rate of warehouse storage but may also lead to the risk of collapse due to the instability of the stack, posing a serious safety hazard. In addition, long-term repetitive bending and carrying actions can easily cause occupational health problems such as lumbar spine and joint problems, further increasing the company's employment risks and management costs.

[0011] Preferably, a connecting column is provided in the middle of the support bracket, a hydraulic device is provided on the connecting column, and a stop column is provided below the hydraulic device.

[0012] Preferably, when the clamping structure clamps the brick layer with the reserved forklift hole, the abutment will move downward under the drive of the hydraulic device to block the position of the reserved forklift hole, so as to avoid damaging the reserved position during clamping and ensure that the forklift forks can be inserted smoothly.

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

[0014] 1. This shale brick production and processing stacking device features a layered modular layout with clear boundaries, facilitating assembly, debugging, and subsequent maintenance. The horizontal displacement of the guide rails and moving platform, combined with the vertical adjustment of the lifting hydraulic column, allows for stacking of bricks of different specifications, meeting the needs of multi-station rotation. The clamping structure is precisely designed, balancing safety and practicality. The rotation system, consisting of a drive motor, reversing structure, conical shaft, and conical turntable, can drive the clamping structure to rotate at multiple angles, improving clamping flexibility and stacking accuracy. The combination of a fixed inclined plate, hydraulic column, and clamping plate, along with an adjusting arm, allows for adjustment of the clamping spacing to accommodate different specifications of shale bricks, conforming to the brick stacking shape and enhancing stability. The support bracket's connecting column-hydraulic device-stop column structure can abut against the forklift's pre-drilled holes during clamping, preventing damage and ensuring smooth subsequent transportation. Furthermore, the lifting and clamping functions are all hydraulically driven, which is more stable, precise, and wear-resistant than traditional mechanical drives, capable of withstanding the weight load of batches of bricks, avoiding downtime due to malfunctions, and ensuring continuous and stable production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1 This utility model provides a technical solution: a stacking device for shale brick production and processing, including a main body 1, a fixed base 2 is provided below the main body 1, a guide rail 3 is provided above the main body 1, a moving platform 4 is provided on the guide rail 3, a limit post 5 is provided on the moving platform 4, a lifting hydraulic column 6 is provided in the middle of the limit post 5, and a clamping structure 7 is provided at the bottom of the lifting hydraulic column 6.

[0022] The clamping structure 7 includes a connecting structure 8, a rotating structure 9 is provided on the connecting structure 8, a support bracket 10 is provided below the rotating structure 9, and a clamping structure 11 is provided on the support bracket 10.

[0023] In this embodiment, the upper connecting structure and rotating structure are responsible for power transmission and direction adjustment, while the lower support bracket and clamping structure are responsible for stable support and core clamping action. This avoids interference between different functional modules, which is convenient for later assembly and maintenance, and can also adapt to the clamping needs of different scenarios through modular design.

[0024] The connecting structure 8 and the rotating structure 9 include a connecting plate 12, a drive motor 13 is provided inside the connecting plate 12, a reversing structure 14 is provided on the drive motor 13, a conical rotating shaft 15 is provided below the reversing structure 14, and a conical turntable 16 is provided below the conical rotating shaft 15.

[0025] The conical turntable 16 is provided with a support bracket 10 at its lower end. The drive motor 13 drives the conical rotating shaft 15 on the reversing structure 14 to rotate. Through the meshing of the bevel gears, the conical turntable 16 is driven to rotate, which in turn drives the support bracket 10 to rotate.

[0026] In this embodiment, a combination of a drive motor, a commutation structure, a conical shaft, and a conical turntable is used. The meshing characteristics of the conical gears efficiently transmit the power of the drive motor to the conical turntable, thereby driving the support bracket to rotate. Compared to ordinary spur gear transmissions, conical gears are more suitable for vertical power steering, with lower transmission losses and controllable steering angles. By embedding the drive motor and commutation structure within the connecting plate, the core components of the rotating structure are concentrated on the same carrier, reducing the risk of swaying from scattered parts, improving overall stability during rotation, and avoiding rotational offset problems caused by dispersed components.

[0027] The clamping structure 11 includes a clamping arm 17 and an adjusting arm 21. The clamping arm 17 and the adjusting arm 21 include a fixed inclined plate 18. A hydraulic column 19 is provided below the fixed inclined plate 18, and a clamping plate 20 is provided on the hydraulic column 19.

[0028] In this embodiment, a combination of a fixed inclined plate, a hydraulic column, and a clamping plate is used, leveraging the hydraulic drive characteristics of the hydraulic column to adjust the clamping force of the clamping plate. Compared to a rigid mechanical connection, hydraulic drive allows for flexible pressure adjustment based on the material hardness of the brick layer, ensuring secure clamping while preventing excessive pressure from crushing the brick layer, thus adapting to the clamping requirements of bricks with varying strengths. The dual-arm design of the clamping arm and adjusting arm allows for adjustment of the distance between the two arms to accommodate brick layers of different widths. Simultaneously, the tilt angle of the fixed inclined plate indirectly optimizes the contact area between the clamping plate and the brick layer, further improving clamping stability and reducing the problem of brick edge damage caused by single-point force.

[0029] The support bracket 10 has a connecting column 22 in the middle, a hydraulic device 23 on the connecting column 22, and a stop column 24 below the hydraulic device 23.

[0030] When the clamping structure 11 clamps the brick layer with the reserved forklift hole, the abutment 24 will move downward under the drive of the hydraulic device 23 to block the position of the reserved forklift hole, so as to avoid damaging the reserved position during clamping and ensure that the forklift forks can be inserted smoothly.

[0031] In this embodiment, the abutment moves downward during clamping, pressing against the pre-drilled hole on the forklift, directly solving a key risk in brick clamping. If only the clamping arms hold the sides of the brick layer, the clamping force may deform the pre-drilled hole in the middle of the brick layer, preventing the forklift forks from inserting. The active abutment design of the abutment provides support inside the pre-drilled hole, counteracting the lateral pressure of the clamping arms, fundamentally protecting the structural integrity of the pre-drilled hole, ensuring smooth forklift transport, and avoiding rework or brick layer scrap due to damage to the pre-drilled hole. The abutment's drive source is associated with the support bracket, meaning that the clamping structure's clamping start and the abutment pressing down against the pre-drilled hole can be performed synchronously or in conjunction, eliminating the need for additional manual operation, simplifying the operation process, and avoiding human error of forgetting to press against the pre-drilled hole, thus improving ease of use and safety.

[0032] Working principle: In actual use, after the device is powered on, the fixed base 2 provides overall stable support. The operator sets the horizontal movement path of the moving platform 4 and the initial height of the lifting hydraulic column 6 through the control system according to the position and specifications of the shale bricks to be stacked. At this time, the moving platform 4 is at the initial end of the guide rail 3, and the clamping structure 7 is in the raised state, ready to work. Then, the control system drives the moving platform 4 on the guide rail 3 to move horizontally along the guide rail 3 to directly above the pile of shale bricks to be clamped. The limiting and positioning components of the guide rail 3 ensure that the stopping position of the moving platform 4 is aligned with the middle of the brick pile. To ensure alignment and prevent subsequent clamping misalignment, after the moving platform 4 is positioned, the lifting hydraulic column 6 is activated and drives the clamping structure 7 to descend vertically until the clamping structure 11 is at the same horizontal level as the shale brick layer to be clamped. Simultaneously, the pressure feedback from the hydraulic system precisely controls the descent amplitude to prevent collision damage between the clamping structure 11 and the brick. If there is an angular deviation in the placement of the brick layer to be clamped, the drive motor 13 in the clamping structure 7 is activated, changing the power direction through the reversing structure 14 and driving the conical rotating shaft 15 to rotate. The conical turntable 16 is then driven by the meshing of conical gears. The rotation causes the support bracket 10 and clamping structure 11 connected below the turntable to rotate synchronously to an angle matching the brick layer. Simultaneously, the hydraulic column 19 on the clamping arm 17 and adjusting arm 21 drives the clamping plate 20 to extend and retract, adjusting the spacing of the clamping plates 20 according to the shale brick size to fit the sides of the brick. After the clamping plate 20 spacing is adjusted, the hydraulic column 19 applies pressure to clamp the shale brick layer, thus fixing it in place. If a forklift hole needs to be pre-drilled, the hydraulic device 23 on the middle connecting column 22 of the support bracket 10 is activated, driving the abutment column 24 downwards until it is inserted into the shale brick layer by the forklift. The vehicle pre-drills holes and presses against the hole walls to prevent excessive clamping force from squeezing and damaging the shape of the pre-drilled holes, ensuring that the forks can be smoothly inserted during subsequent forklift transportation. After the shale brick layer is clamped and fixed, the lifting hydraulic column 6 drives the clamping structure 7 to rise synchronously with the brick and leave the original position. Then, the moving platform 4 moves along the guide rail 30 to above the target stacking area. The lifting hydraulic column 6 descends again to place the brick in the designated position. After the stacking is completed, the clamping plate 20 is released, the abutment column 24 retracts upward, the lifting hydraulic column 6 drives the clamping structure 7 to lift, and the moving platform 4 returns to the initial position to enter the next stacking cycle.
