Description

Technical Field

[0001] The utility model relates to the technical field of round steel hoists, in particular to a forged round steel hoisting device. Background Art

[0002] Round steel hangers, also known as round steel clamps, are devices used to fix round steel objects in the mechanical manufacturing process so that they occupy the correct position for construction or testing.

[0003] The utility model patent with authorization announcement number CN 202296843 U discloses a sling for lifting round steel. First, the earring bolt of the sling is hung on the hook, and the ferrule is rotated to move the ferrule up and open two claws, and the round steel is placed between the two claws. The round steel is clamped under the action of gravity, and the ferrule is rotated again to move it down. The hinged ear of the claw is pressed by the ferrule bell mouth to prevent the claw from opening, and then the round steel is lifted. The above-mentioned prior art scheme still has the following shortcomings: the round steel is lifted only by a single sling. If the claw is not clamped in the middle section of a round steel and the round steel is long, the round steel is prone to tilt or even slip during the lifting process, and there are certain safety hazards. Therefore, a forged round steel lifting device is proposed to solve the above-mentioned problems. Utility Model Content

[0007] Preferably, the dual-axis servo motor is fixedly connected to the inside of the installation frame, and the dual-axis servo motor is electrically connected to the mobile power source through a wire.

[0008] Through the above technical solution, by turning on the power switch of the mobile power supply, power can be supplied to the dual-axis servo motor to achieve adjustment of the positions of the two threaded blocks.

[0009] Preferably, the opposite sides of the two threaded rods are rotatably connected to the left and right sides of the inner wall of the installation frame respectively, and the threads on the two threaded rods are equal in length and opposite in direction.

[0010] Through the above technical solution, since the threads on the two threaded rods are of equal length and in opposite directions, the two threaded blocks can move away from each other or relatively by the same distance under the drive of the dual-axis servo motor.

[0011] Preferably, first limiting grooves are provided on both the front and rear sides of the inner wall of the installation frame, and the size of the first limiting grooves is adapted to the moving track of the first limiting block.

[0012] Through the above technical solution, under the joint restriction of the first limiting block and the first limiting groove, the threaded block can be prevented from rotating with the threaded rod, thereby preliminarily ensuring the moving direction and moving distance of the threaded block.

[0013] Preferably, a second limiting groove is formed on the inner top wall of the installation frame, and the size of the second limiting groove is adapted to the moving track of the second limiting block.

[0014] Through the above technical solution, under the joint restriction of the second limiting block and the second limiting groove, the threaded block can be prevented from rotating with the threaded rod, further ensuring the moving direction and moving distance of the threaded block.

[0015] Preferably, the clamping mechanism comprises a U-shaped frame, the front and rear sides of the U-shaped frame are fixedly connected to electric push rods, and the output end of the electric push rod is fixedly connected to a clamping plate.

[0016] Preferably, the U-shaped frame is fixedly connected to the bottom of the connecting rod, the output end of the electric push rod extends to the inside of the U-shaped frame and is fixedly connected to a clamping plate, the clamping plate is arc-shaped, and the opposite sides of the clamping plate on the front and rear sides are fixedly connected with anti-slip pads.

[0017] Through the above technical solution, the arc-shaped clamping plate can better clamp the round steel, and the installation of the anti-skid pad can prevent the round steel from sliding during the lifting process.

[0018] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0019] First, when the round steel to be hoisted is relatively long, the utility model starts the double-axis servo motor to rotate forward under the power supply of the mobile power supply, and under the restriction of the first limit block and the second limit block, the two threaded blocks drive the connecting rods to move away from each other, thereby increasing the distance between the two U-shaped frames, and clamping the longer round steel. If the round steel is relatively short, the double-axis servo motor is started to rotate reversely, which can reduce the distance between the two U-shaped frames, and hang the lifting ring on the top of the installation frame on the lifting buckle at the lower end of the electric hoist wire rope, so as to realize the lifting of round steels of different lengths.

[0020] Second, the utility model places the round steel between the front and rear clamping plates, and starts the electric push rod to extend its output end, so that the front and rear clamping plates move relatively until the round steel is clamped. The installation of the anti-skid pad can prevent the round steel from sliding during the hoisting process. BRIEF DESCRIPTION OF THE DRAWINGS
