Description

Technical Field

[0001] The utility model relates to the technical field of imitation stone block transportation, in particular to an imitation stone block lifting arm. Background Art

[0002] In the production process of stone slabs, the loading and unloading of finished stone slabs is undoubtedly one of the most important links. As an important material in the fields of building decoration, stone slabs need to be loaded and unloaded and transferred efficiently and safely after production is completed so that they can smoothly enter the subsequent storage, transportation and practical application links. Generally speaking, as the area of stone slabs gradually increases, their thickness will also show a corresponding increasing trend, and the weight will increase significantly. This not only brings greater challenges to the loading and unloading work, but also puts higher requirements on the corresponding loading and unloading equipment and technology. In the actual operation process, if the appropriate loading and unloading method is not adopted, it will not only affect the production efficiency, but also may cause damage to the stone slabs and even pose a threat to the safety of the operators. Therefore, choosing the appropriate loading and unloading method for stone slabs is particularly critical.

[0003] The Chinese utility model patent announcement number is: CN219807669U, which discloses a stone slab loading and unloading device. This device deforms downward through the weight of the first arm and the second arm, so that the pressure block clamps the stone slab, and then uses the stone slab itself to pull down the first arm and the second arm. The heavier the stone slab, the greater the squeezing force of the pressure block, and the more stable the stone slab is clamped, which is convenient for workers to load and unload safely and improves loading and unloading efficiency. However, this stone slab loading and unloading device has certain shortcomings. It is not designed with multiple loading and unloading structures, and only clamps the stone slab in a single way, which is difficult to adapt to various different working conditions. At the same time, it is not designed with an angle adjustment structure and a clamping claw, which makes it difficult to achieve angle adjustment, resulting in a limited working range and large limitations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an imitation stone block lifting arm, which can effectively solve the problem that the prior art does not design a variety of loading and unloading structures, only uses a single method to clamp the stone slabs, which is not convenient for adapting to a variety of different working conditions, and at the same time does not design an angle adjustment structure, and designs clamping claws, which is not convenient for achieving angle adjustment, resulting in a large working range and limitations.

[0005] The technical solution adopted by the present invention is: an imitation stone block lifting arm, comprising a base, a connectable rod fixedly installed on the top of the base, a fixed plate fixedly installed on the top of the connecting rod, a fixed rod fixedly installed on the top of the fixed plate, an oblique rod fixedly installed on the outside of the fixed rod, a cross bar fixedly installed on the top of the fixed rod, a rotating shaft rotatably installed on the outside of the cross bar, a reinforcing block 1 fixedly installed on the outside of the rotating shaft, an oil cylinder provided on the outside of the reinforcing block 1, a connecting shaft fixedly installed on the output shaft of the oil cylinder, a lifting assembly fixedly installed on the top of the cross bar, a fixed block fixedly installed on the outside of the lifting assembly, and a reinforcing rib 2 fixedly installed on the top of the connecting rod.

[0006] Preferably, the lifting assembly includes a second reinforcement block fixedly installed on the outside of the lifting rod, a rotating shaft is provided on the outside of the top of the lifting rod, a lifting arm rod is rotatably installed on the lifting rod through the rotating shaft, a connecting seat is fixedly installed on the outside of the lifting arm rod, and two identical reinforcement blocks are provided and are symmetrically distributed about the center line of the lifting rod.

[0007] Through the above technical solution, through the design of two reinforcing blocks 2, the deformation resistance of the lifting rod can be increased during the use of the overall lifting arm, thereby preventing the lifting rod from being easily deformed, causing damage to the overall lifting arm and affecting normal use.

[0008] Preferably, a winch is fixedly installed on the top of the lifting arm, a steel wire rope is fixedly installed on the winch roller, a mounting plate is fixedly installed on the other end of the steel wire rope away from the winch, a hanging seat is fixedly installed on the bottom of the mounting plate, and three of the hanging seats are provided, two of which are provided with lifting chains at the bottom and one of which is provided with a hook at the bottom.

[0009] Through the above technical solution, by setting up three hanging seats, two of which are equipped with hanging chains and one is equipped with a hook, a variety of options are provided for lifting imitation stone blocks of different shapes and sizes. For some imitation stone blocks with irregular shapes, uneven surfaces or large sizes, the hanging chain can more flexibly surround and fix the stone blocks, and the hook can perform lifting operations quickly and conveniently. The choice can be made according to actual conditions.

[0011] Through the above technical solution and the design of the wire rope, when the wire rope passes through pulley one and pulley two, pulley one and pulley two can effectively reduce the friction of the wire rope and extend the service life of the wire rope. At the same time, the guiding effect of pulley one and pulley two can make the wire rope more stable when lifting and lowering heavy objects, avoiding the phenomenon of wire rope entanglement or jumping, thereby improving the safety and stability of the lifting process.

When the lifting arm is working, it will bear forces from all directions, including the pulling force when lifting heavy objects, its own weight and possible wind loads. The reinforcing ribs can effectively disperse these forces and prevent stress from being concentrated at the connection between the connecting rod and the base, thereby extending the service life of the equipment and reducing the risk of damage due to weak connection parts.

[0016] Preferably, the cross bar is rotatably mounted with the reinforcement block 1 via a rotating shaft, and the reinforcement block 1 and the oil cylinder are an integrated structure.

[0017] Through the above technical solution and the design of the oil cylinder, when the angle needs to be adjusted, the oil cylinder can be used to drive the lifting assembly to adjust the angle, and at the same time the lifting arm can be rotated through the rotating shaft and the lifting rod, thereby improving its practicality.

When the steel wire rope passes through pulleys 1 and 2, pulleys 1 and 2 can effectively reduce the friction of the steel wire rope, thereby extending the service life of the steel wire rope. At the same time, the guiding effect of pulleys 1 and 2 can make the steel wire rope more stable when lifting and lowering heavy objects, avoiding the phenomenon of steel wire rope entanglement or jumping, thereby improving the safety and stability of the lifting process;

[0021] 3. The imitation stone block lifting arm, the connecting seat and the connecting shaft are rotatably installed, so that the lifting arm rod can swing to a certain angle under the action of the oil cylinder, which can further expand the working range of the lifting arm and enable the lifting arm to more flexibly adapt to the lifting needs of different positions and angles.
