Description

Technical Field

[0001] This utility model relates to the field of aerated concrete block production technology, specifically to an aerated concrete block transfer clamp. Background Technology

[0002] Aerated concrete blocks are a commonly used material in modern construction. After manufacturing, they need to be transported to the construction site. During this process, they need to be loaded onto trucks. Currently, in order to improve loading efficiency, multiple aerated concrete blocks are often clamped together for transport.

[0003] At present, the aerated concrete block transfer clamps are mainly pneumatic or hydraulic. They use a frame structure to protect the aerated concrete block and control the frame to hold it. However, in order to ensure strength, the control frame is mostly made of metal. During the clamping process, the hydraulic force cannot determine whether the aerated concrete block is clamped, and manual judgment is required. Therefore, it is easy to cause damage to the surface of the block. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aerated concrete block transfer clamp that meets complex stacking requirements, ensures uniform stress on the blocks, and reduces downtime due to malfunctions.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an aerated concrete block transfer clamp, including a lifting block, the lifting block being installed at the front end of a forklift, a rotating disk being connected to the front side of the lifting block, and left and right extending guide rails being respectively provided on the left and right sides of the rotating disk, characterized in that clamping components are assembled on the guide rails;

[0006] The clamping assembly includes a guide slider, which is mounted on a guide rail. A clamping frame is connected to the guide slider. The clamping frame is an L-shaped frame, and a protective pad is provided on the inner side of the clamping frame.

[0007] The left and right clamping frames are respectively equipped with power rails, which are set parallel to the guide rails and are connected to the guide rails. Power sliders are mounted on the power rails, which extend into the guide rails and are connected to the guide sliders. The power sliders are respectively connected to the telescopic ends of their respective power hydraulic cylinders.

[0008] The rotating disk is equipped with a detection tube for each power hydraulic cylinder. Each detection tube contains a piston. The end of the detection tube extends to the outside of the rotating disk and is connected to a connecting bend. The connecting bend is connected to the inner cavity of the power hydraulic cylinder. A detector is connected to one side of the piston.

[0009] In the above scheme: the guide slider is a rectangular structural plate, and the cross-section of the guide rail matches the guide slider. The sliding friction coefficient is reduced to ensure the translational stability of the clamping frame.

[0010] In the above solution: the clamping frame and the guide slider are connected by a connector, which is a threaded rod. A high-strength threaded rod, combined with an anti-loosening nut, enables quick assembly and disassembly.

[0011] In the above scheme: the detector includes a detection guide rod, the end of which is connected to the piston, a return spring is sleeved on the outer sleeve of the detection guide rod, a detection sleeve is provided on the side of the detection tube away from the piston, a pressure sensor is provided inside the detection sleeve, and the detection guide rod extends into the detection sleeve and contacts the pressure sensor.

[0012] In the above scheme: the detection sleeve is a cylindrical shell, and a compression seat is provided at the inner end of the detection sleeve.

[0013] In the above scheme: the protective pad is a flexible plate with a rectangular structure.

[0014] The aerated concrete block transfer clamp provided by this utility model has the following beneficial effects: This aerated concrete block transfer clamp improves clamping safety through intelligent detection and structural optimization. Specifically, it meets complex stacking requirements by coordinating the rotation disk orientation adjustment, lifting block height control, and guide rail translation accuracy. It can realize the linkage between the dual-side detectors and independent hydraulic cylinders to compensate for clamping force deviation in real time, ensuring uniform force on the bricks. The hydraulic action is stopped in time when the clamping force is in place. The modular design of the protective pad and detector components supports quick disassembly and replacement, reducing downtime due to failure. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, the aerated concrete block transfer fixture includes a lifting block 1, which is mounted on the front of a forklift for lifting. A rotating disk 2 is connected to the front of the lifting block 1. Left and right extending guide rails 3 are respectively provided on the left and right sides of the rotating disk 2. The figure shows a pair of guide rails 3 on each side, located at the upper and lower parts of the left and right sides of the rotating disk, respectively. The guide rails 3 are grooved rails, and clamping components are mounted on the guide rails 3. The rotating disk 2 can drive the clamping components to rotate at multiple angles to adapt to different stacking directions. The structure of the rotating disk 2 is existing technology, and its rotation is controlled by a motor located on the back of the lifting block 1.

[0021] The clamping assembly includes a guide slider 4, which is a rectangular structural plate. The cross-section of the guide rail 3 matches that of the guide slider 4. The guide slider 4 is mounted on the guide rail 3 to ensure that the clamping assembly slides smoothly along a straight line and avoids deviation. Clamping frames 5 are connected to both the left and right guide sliders 4. The clamping frames 5 are L-shaped frames, and protective pads 6 are provided on the inner side of the clamping frames 5. The polyurethane elastomer surface of the protective pads 6 has anti-slip textures to increase the coefficient of friction and prevent the bricks from slipping during transport. The protective pads 6 are rectangular flexible plates.

[0022] The clamping frames 5 on both sides are arranged opposite each other, and the bricks are clamped between the protective pads 6. The combination of the rotating disk 2 and the lifting block 1 realizes the orientation adjustment, and with the precision sliding pair of the guide slider 4, the fixture can adapt to complex stacking scenarios.

[0023] Specific examples Figure 1 The clamping frame 5 is formed by two L-shaped rods, one above the other, and a connecting rod between the L-shaped rods, creating an L-shaped frame structure. The upper and lower L-shaped rods are respectively connected to the corresponding upper and lower guide sliders 4. Preferably, the clamping frame 5 and the guide sliders 4 are connected by a connector, which is a threaded rod.

[0024] The left and right clamping frames 5 are each equipped with a power rail 7, which is parallel to the guide rail 3 and runs through it. It is also a groove-shaped rail. A power slider 8 is slidably connected to the power rail 7. The power slider 8 extends into the guide rail 3 and connects with the guide slider 4. The power slider 8 is connected to the telescopic end of its respective power hydraulic cylinder 9.

[0025] A detection tube 10 is installed on the rotating disk 2 for each power hydraulic cylinder 9. A piston 11 is fitted inside each detection tube 10. The end of the detection tube 10 extends to the outside of the rotating disk 2 and is connected to the connecting bend 12. The connecting bend 12 is connected to the hydraulic cylinder cavity of the power hydraulic cylinder 9. Hydraulic oil can enter the detection tube 10. A detector is connected to one side of the piston 11.

[0026] The detector includes a detection guide rod 13, the end of which is connected to the piston 11. A return spring 14 is sleeved around the detection guide rod 13. A detection sleeve 15 is located inside the detection tube 10 on the side furthest from the piston 11. A pressure sensor 16 is located inside the detection sleeve 15. The detection guide rod 13 extends into the detection sleeve 15 and contacts the pressure sensor 16. Preferably, the detection sleeve 15 is a cylindrical shell, and a compression seat is located at the inner end of the detection sleeve 15, which is the end furthest from the piston. The pressure sensor 16 is mounted on the compression seat.

[0027] The clamping frame 5 of the clamping assembly has an L-shaped structure, and the inner protective pad 6 is wrapped with a flexible material to disperse local pressure when in contact with the aerated concrete block. The power hydraulic cylinder 9 pushes the power slider 8 to move through its telescopic end, causing the clamping frame 5 to close or open. The detection pipe 10 is connected to the power hydraulic cylinder 9 through the connecting bend 12. The piston 11 moves with the clamping force, triggering the detector to provide real-time feedback pressure signals, forming a closed-loop control. This control method is existing technology and will not be elaborated here. The combination of the L-shaped frame and the protective pad 6 reduces local pressure by contacting the aerated concrete block at multiple points.

[0028] The detector's detection guide rod 13 is linked with the piston 11. When the clamping force is applied to the extrusion seat, the return spring 14 is compressed and triggers the signal of the pressure sensor 16, which can realize the automatic adjustment of the output pressure of the hydraulic system to prevent overload. The flexible characteristics of the protective pad 6 buffer the contact impact, and together with the rigid support of the clamping frame 5, it protects the brick surface and ensures stable clamping. The pressure sensor 16 monitors the clamping force threshold in real time, and can automatically cut off the hydraulic power when the limit is exceeded, avoiding damage to the brick caused by human misjudgment.

[0029] The pressure sensor 16 can be interlocked with the hydraulic system. When the clamping force fluctuation exceeds a certain amount, the compensation program is automatically started to synchronously adjust the pressure of the hydraulic cylinders on both sides to balance the deviation.

[0030] This aerated concrete block transfer clamp can achieve intelligent detection and structural optimization to improve clamping safety. Specifically, it uses the coordinated operation of the rotary disc 2 for orientation adjustment, the lifting block 1 for height control, and the guide rail 3 for translational accuracy to meet complex stacking requirements. The dual-sided detectors are linked with independent hydraulic cylinders to compensate for clamping force deviations in real time, ensuring uniform force on the bricks. The hydraulic action is stopped in time when the clamping force is in place. The modular design of the protective pad 6 and detector components supports quick disassembly and replacement, reducing downtime due to failure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
