Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated brick production, in particular to a lifting device for lifting prefabricated bricks. Background Art

[0002] Precast bricks are concrete bricks produced and processed in a prefabrication yard and transported directly to the construction site for installation, hence the name precast bricks. There are many types of precast bricks, and different types of precast bricks are used according to different construction environments. During production, concrete is pressed into shape, then extruded and demolded, and after solidification, the precast bricks are moved by a lifting device.

[0003] When lifting precast bricks, most existing devices use a clamping method to clamp and transfer the precast bricks. However, when the clamping parts are extended and retracted according to the size of the precast bricks, they are prone to being out of position, and the strength of the clamping and fixing of the precast bricks is low, which makes them prone to loosening. In the subsequent stacking process, position deviations are prone to occur, leading to tipping.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lifting device for lifting prefabricated bricks is proposed, in order to achieve a more practical purpose. Utility Model Content

[0023] By setting up four groups of horizontal clamping components 5, the horizontal hydraulic rod 501 is used to drive the clamping plate 504 to approach the precast bricks to achieve contact clamping, and cooperate with the guide rod 503 installed on the bracket plate 502 to double limit the position of the bracket plate 502 to ensure the stable movement of the bracket plate 502, thereby ensuring the stable clamping of the precast bricks;

[0024] Cooperating with the lifting hydraulic rod 3 installed on the top, the lifting platform 1 can be driven to be raised and lowered with it, and the pad 6 at the bottom can be fitted with the surface of the precast bricks, so as to flatten the precast bricks and avoid misalignment, which affects the pressurization effect;
