The up and down lifting synchronization is good, with self-locking and high efficiency, equipped with four guide wheels, the lifting movement is accurate and stable.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Figure 1 is a schematic diagram of the combined device model.

detailed description

Preferably, the cut and formed ceramsite blocks follow the conveying line and enter the stacking system device. The frame of the lifting platform is flush with the conveying line at this time, and the blocks are sent into the frame of the lifting platform row by row through the conveying line, and the blocks are ready to be stacked. After the combination is stable, the lifting device drives the lifting frame to rise to a certain height, and the translation pushing plate in the horizontal pushing clamping device moves laterally under the drive of the motor belt, and when it moves directly above the rotating device, the lifting frame drops to the specified height , at this time, the cylinder in the horizontal push device respectively pushes the block baffle to hold the two rows of blocks, and the translation push plate is pulled out from the bottom of the block at this time, and then lowered to a certain height, the cylinder push plate returns to the initial position, and the Two rows of blocks are lightly placed on the wooden pallet, and the work of one layer is completed, which is carried out sequentially. In addition, in order to ensure cross-stacking, the rotating device will rotate 90° every other layer until 6 layers of stacking are completed.

Preferably, as shown in Figure 1, the first row of blocks and the second row of blocks follow the movement of the powered roller conveyor belt. When the first row of blocks touches the unpowered roller, the cylinder pushes the baffle to swing to a designated position. When a row of blocks is completely separated from the power roller, it will touch the baffle device. At this time, the first row of blocks stops moving and waits for the second row of blocks. When the second row of blocks contacts the first row, the conveyor belt stops moving. , the baffle device returns to the initial position, and the two rows of blocks are merged, waiting for palletizing.

Preferably, the clamping claws are pushed by a hydraulic cylinder to perform opening and closing reciprocating movement along the guide shaft, and the clamping starts when the clamping position of the clamping claws touches the side of the block.

Preferably, in order to ensure that there is no too much damage to the corners of the blocks during stacking, a rubber diaphragm with a certain thickness is fixed at the clamping position of the claws to buffer the impact during the clamping process.

Preferably, in order to improve the synchronization and stability of the two pairs of clamping claws clamping the block, a synchronization device push rod mechanism is installed between the two pairs of clamping claws.

Preferably, in order to ensure the stability during the rotation of the clamping device, a swing cylinder is used to drive the rotation center device to rotate, wherein the outer cover of the rotation center device is fixed on the fixed frame, the rotating shaft and the clamping device are fixedly connected with bolts, and the swing cylinder drives The rotating center shaft rotates, and then drives the clamping device to rotate. A thrust ball bearing and two deep groove ball bearings are installed in the rotating center device so that the rotating center shaft will not be eccentric when rotating.

Preferably, the lifting motion is driven by the chain to move the platform frame up and down, and the lateral movement is realized by the meshing of the gear driven by the motor and the rack.

Preferably, there is an output motor at both ends above the frame, which drives the movement of the worm gear shaft in the worm gear and worm box on both sides through the transmission connection shaft, and then drives the sprocket fixed on the worm gear shaft to rotate. There are two sprockets on each side. The lifting traction chain is fixed to the platform frame through the chain connector, thereby realizing the up and down movement of the platform frame.

Preferably, four guide rollers are fixed at the four corners of the platform frame, and the rollers roll up and down on the inner sides of the four columns of the frame to realize the guiding function and ensure the accuracy of the up and down movement of the platform frame.

Preferably, in order to ensure the synchronization of the up and down movement of the left and right sides of the frame, a motor is provided to drive the worm gear box on both sides. Since the worm gear has self-locking properties, the stability and safety of the up and down movement can be ensured.
