Description

Technical Field

[0001] This utility model relates to the field of board breaking machine technology, specifically to an aerated concrete platform lifting structure for a board breaking machine. Background Technology

[0002] A plate breaking machine is an important piece of equipment in an aerated concrete production line. It is mainly used to separate and re-stack the cut and molded concrete blocks along the cut seam. It can automatically complete the breaking process. A plate breaking machine generally includes a frame, a lifting device, and a plate breaking device. Taking a fixed plate breaking machine used in an ALC production line as an example, it usually adopts a chain lifting mechanism. The lateral lifting of the bracket is achieved through the cooperation of the synchronous shaft and the tie rod. During operation, the upper clamping beam clamps the upper ALC plate, the lower clamping beam clamps the lower ALC plate, and then the upper clamping beam is lifted by hydraulic drive to separate the adhered plates.

[0003] Chinese Patent Publication No. CN110253748A discloses an aerated concrete breaking machine. By activating the hydraulic cylinder in the tie rod mechanism, the hydraulic cylinder drives the tie rod body to move, thereby separating the cut concrete blocks along the cut seam. The hydraulic cylinder drives the telescopic end to retract and restore, thereby driving the tie rod body to return to its original state and re-stack the separated concrete blocks together.

[0004] In practical use, the clamp holds both sides of the aerated concrete block, while the hydraulic cylinder extends and drives the clamp and the aerated concrete block upward through the pull rod. The extension and retraction of the hydraulic cylinder needs to overcome the weight of the aerated concrete block itself, as well as the adhesive force between the upper and lower aerated concrete blocks. As a result, the hydraulic cylinder piston is subjected to a large reaction force. The hydraulic cylinder is subjected to axial force for a long time and high frequency, which leads to metal fatigue and makes the piston rod prone to plastic deformation, resulting in movement jamming. Therefore, an aerated concrete platform lifting structure for a plate breaking machine is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aerated concrete platform lifting structure for a plate breaking machine. This structure has the advantage of reducing the reaction force on the hydraulic cylinder, solving the problem of the hydraulic cylinder extending and pulling the clamps and aerated concrete blocks upwards via a tie rod when the clamps hold both sides of the aerated concrete block. This requires the hydraulic cylinder to overcome the weight of the aerated concrete block itself, as well as the adhesive force between the upper and lower blocks, resulting in the piston being subjected to a large reaction force. Long-term, high-frequency axial force exposure can easily cause plastic deformation of the piston rod, leading to movement stagnation and reduced service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aerated concrete platform lifting structure for a board breaking machine, comprising a breaking frame, wherein a platform lifting structure for controlling the lifting and lowering of clamps is provided on the breaking frame;

[0007] The lifting structure includes a connecting bracket mounted on the dividing frame, a trapezoidal block fixedly connected to the bottom of the connecting bracket, a pressing component for pressing the trapezoidal block on the dividing frame, and a driving component for controlling the pressing component on the dividing frame.

[0008] The extrusion component includes two extrusion blocks, which are symmetrically arranged on both sides of the trapezoidal block. Both extrusion blocks are provided with a slope, and the slope is coplanar with the inclined surface of the trapezoidal block.

[0009] The driving component includes two irregularly shaped racks that are slidably mounted on the splitting frame, and the irregularly shaped racks on the same side are connected to the extrusion blocks on the same side. Gears that mesh with the two irregularly shaped racks are rotatably mounted on the splitting frame, and the two irregularly shaped racks are symmetrical about the central axis of the gears. Two hydraulic cylinders are fixedly mounted on the splitting frame, and the extension and retraction ends of the two hydraulic cylinders are fixedly connected to one of the extrusion blocks.

[0010] Furthermore, the trapezoidal block has an irregularly shaped groove inside to reduce its own weight, and guide grooves are provided on both sides of the trapezoidal block.

[0011] Furthermore, the connecting bracket includes a connecting frame, and the connecting frame is fixedly connected to the trapezoidal block, and a plurality of reinforcing ribs are fixedly installed on the connecting frame.

[0012] Furthermore, two limiting grooves symmetrically distributed around the central axis of the gear are fixedly installed on the splitting frame, and two guide strips symmetrically distributed are fixedly installed on the splitting frame, with the guide strips slidably connected to the guide grooves.

[0013] Furthermore, the irregular rack includes a rack segment, a limiting segment, and a connecting segment. The limiting segment is slidably connected to the limiting groove. Several pins are fixedly installed on the connecting segment, and several connecting holes adapted to the pins are opened on the extrusion block.

[0014] Furthermore, the splitting frame is provided with four aerated concrete clamping structures, two of which are slidably installed on the splitting frame, and the connecting frame is fixedly connected to the two slidably installed aerated concrete clamping structures respectively.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The aerated concrete platform structure of this breaking machine utilizes the slope of the extrusion block and the inclined surface of the trapezoidal block to convert the lateral force output by the hydraulic cylinder into a vertical force that pushes the trapezoidal block upward. This avoids the hydraulic cylinder directly bearing the vertical weight of the aerated concrete and the bonding force of the breaking action, allowing the cylinder to mainly bear the lateral force and reducing the axial force. This prevents the hydraulic cylinder from being subjected to axial force at high frequency for a long time, which could lead to plastic deformation. Furthermore, the gear meshes with two centrally symmetrical irregular racks to ensure that the two extrusion blocks move closer or further away synchronously, resulting in uniform force on the trapezoidal block and smooth lifting, thereby extending the service life of the equipment. In addition, the reinforcing ribs of the connecting bracket enhance the structural strength and can withstand the weight load of the aerated concrete blocks. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1-7 The aerated concrete platform lifting structure of the plate breaking machine in this embodiment includes a breaking frame 1, and a platform lifting structure 2 for controlling the lifting and lowering of the clamps is provided on the breaking frame 1.

[0027] Example 2: Please refer to Figure 1-7 Based on Embodiment 1, the lifting structure 2 includes a connecting bracket 21 installed on the splitting frame 1. A trapezoidal block 22 is fixedly connected to the bottom of the connecting bracket 21. A pressing component 23 for pressing the trapezoidal block 22 is provided on the splitting frame 1. A driving component 24 for controlling the pressing component 23 is provided on the splitting frame 1.

[0028] The extrusion component 23 includes two extrusion blocks 231, which are symmetrically arranged on both sides of the trapezoidal block 22. Each of the two extrusion blocks 231 is provided with a slope 232, and the slope 232 is coplanar with the inclined surface of the trapezoidal block 22. By utilizing the cooperation between the slope 232 of the extrusion block 231 and the inclined surface of the trapezoidal block 22, the lateral force is converted into a vertical force that pushes the trapezoidal block 22 upward.

[0029] In addition, the drive component 24 includes two irregular racks 241 that are slidably mounted on the splitting frame 1, and the irregular racks 241 on the same side are connected to the extrusion blocks 231 on the same side. Gears 242 that mesh with the two irregular racks 241 are rotatably mounted on the splitting frame 1, and the two irregular racks 241 are symmetrical about the central axis of the gears 242. Two hydraulic cylinders 243 are fixedly mounted on the splitting frame 1, and the extension and retraction ends of the two hydraulic cylinders 243 are fixedly connected to one of the extrusion blocks 231. Since the two irregular racks 241 are meshed by the gears 242 and are symmetrical about the central axis, when one extrusion block 231 moves, the other extrusion block 231 moves towards the trapezoidal block 22 synchronously under the transmission of the gears 242.

[0030] By adopting the above technical solution, the slope 232 of the extrusion block 231 is used to cooperate with the inclined surface of the trapezoidal block 22 to convert the lateral force output by the hydraulic cylinder 243 into a vertical force that pushes the trapezoidal block 22 upward. This avoids the hydraulic cylinder 243 directly bearing the vertical gravity and bonding force of the aerated concrete. In addition, the gear 242 meshes with two centrally symmetrical irregular racks 241 to ensure that the two extrusion blocks 231 move closer or further away at the same time, so that the trapezoidal block 22 is subjected to uniform force and lifted smoothly.

[0031] Example 3: Please refer to Figure 1-7 Based on Embodiment 2, the connecting bracket 21 includes a connecting frame 211, and the connecting frame 211 is fixedly connected to the trapezoidal block 22. Several reinforcing ribs 212 are fixedly installed on the connecting frame 211. The trapezoidal block 22 has an irregular groove 221 inside for reducing its own weight, and guide grooves 222 are provided on both sides of the trapezoidal block 22.

[0032] Among them, two limiting grooves 11 are fixedly installed on the splitting frame 1, which are symmetrically distributed around the central axis of the gear 242. Two guide bars 12 are fixedly installed on the splitting frame 1, which are symmetrically distributed and are slidably connected to the guide grooves 222. The sliding cooperation between the guide bars 12 and the guide grooves 222 restricts the lateral displacement of the trapezoidal block 22 and ensures the vertical movement accuracy.

[0033] In addition, the special-shaped rack 241 includes a rack section, a limiting section and a connecting section. The limiting section is slidably connected to the limiting groove 11. Several pins 244 are fixedly installed on the connecting section. Several connecting holes 233 adapted to the pins 244 are opened on the pressing block 231. The limiting groove 11 is used to limit the movement range of the limiting section of the special-shaped rack 241 to avoid slippage or excessive sliding.

[0034] It should be noted that four aerated concrete clamping structures 3 are provided on the splitting frame 1, and two of the aerated concrete clamping structures 3 are slidably installed on the splitting frame 1. The connecting frame 211 is fixedly connected to the two slidably installed aerated concrete clamping structures 3 respectively. The trapezoidal block 22 drives the slidably installed aerated concrete clamping structures 3 to rise through the connecting bracket 21, thereby completing the splitting operation between the upper aerated concrete block and the lower layer.

[0035] Using the above technical solution, the hydraulic cylinder 243 is activated, pushing the extrusion block 231 on the same side to move laterally towards the trapezoidal block 22. Since the two irregularly shaped racks 241 are meshed by the gear 242 and are centrally symmetrical, when one side of the extrusion block 231 moves, the other side of the extrusion block 231 moves towards the trapezoidal block 22 synchronously under the transmission of the gear 242. The slope surface 232 of the extrusion block 231 contacts and extrudes the inclined surface of the trapezoidal block 22. The lateral thrust is converted into an upward vertical component force, which pushes the trapezoidal block 22 to move upward. The trapezoidal block 22 drives the slidingly installed aerated concrete clamping structure 3 to rise through the connecting bracket 21, completing the separation operation between the upper aerated concrete block and the lower layer.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, the aerated concrete platform structure of the plate breaking machine has the trapezoidal block 22 located between two extrusion blocks 231. The slope 232 of the extrusion block 231 is coplanar with the inclined surface of the trapezoidal block 22 but no extrusion occurs. The platform structure 2 is in a low position, and the aerated concrete clamping structure 3 clamps the aerated concrete block to be separated. This is the initial state.

[0038] When the drive unit 24 is activated, the two cylinders 243 extend and push the extrusion block 231 on the same side to move laterally toward the trapezoidal block 22. Since the two irregular racks 241 are meshed by the gear 242 and are centrally symmetrical, when one side of the extrusion block 231 moves, the other side of the extrusion block 231 moves toward the trapezoidal block 22 synchronously under the transmission of the gear 242.

[0039] The slope 232 of the extrusion block 231 contacts and extrudes the inclined surface of the trapezoidal block 22. The lateral thrust is converted into an upward vertical component force, which pushes the trapezoidal block 22 to move upward. The trapezoidal block 22 drives the slidingly installed aerated concrete clamping structure 3 to rise through the connecting bracket 21, thus completing the separation operation between the upper aerated concrete block and the lower layer.

[0040] The hydraulic cylinder 243 retracts, causing one side of the extrusion block 231 to move away from the trapezoidal block 22. The other side of the extrusion block 231 moves away synchronously under the reverse transmission of the gear 242. The trapezoidal block 22 descends under the action of gravity as it separates from the extrusion block 231. The aerated concrete clamping structure 3 drives the separated aerated concrete blocks to reset and stack.
