Description

Technical Field

[0001] This utility model belongs to the technical field of steel pipe mobile equipment, and more specifically, relates to a dual-station steel pipe lifting mechanism. Background Technology

[0002] During the production of steel pipes, due to space limitations or different process requirements, a handling mechanism is needed to transfer the steel pipes processed in the previous process to the next process for continued processing. Currently, one method is manual transfer. However, since steel pipes are generally heavy, manual transfer is unsafe and labor-intensive. Existing steel pipe moving equipment has poor load-bearing capacity, complex structure, high manufacturing cost, poor lifting stability, and short lifting height stroke, which limits its practical application and is very inconvenient.

[0025] A dual-position steel pipe lifting mechanism includes at least two sets of steel pipe lifting assemblies 10 and several connecting shafts 20. Adjacent steel pipe lifting assemblies 10 are connected by the connecting shafts 20. Each steel pipe lifting assembly 10 includes a frame 30, a support plate 40, and a hydraulic cylinder 50. The support plate 40 is used to place steel pipes. Support frames 60 are connected to the four corners of the frame 30. A bearing seat 70 is connected to the top of each support frame 60. The connecting shafts 20 are flexibly connected to the bearing seats 70. The hydraulic cylinder 50 is connected to the platform 30 via a dynamic connection. The driving end of the hydraulic cylinder 50 is equipped with an active crank arm 80. One end of the active crank arm 80 is connected to the driving end of the hydraulic cylinder 50, and the other end is sleeved on the connecting shaft 20. A first driven crank arm 90 is sleeved on the connecting shaft 20. A transmission shaft 100 is located on one side of the hydraulic cylinder 50. One end of the first driven crank arm 90 is connected to the transmission shaft 100, and the other end is connected to a first support arm 110 and the support plate 40. The transmission shaft 100 is connected to a second driven crank arm 120 at one end away from the first driven crank arm 90, and a pin 130 is provided to be sleeved with the second driven crank arm 120. The two ends of the pin 130 are movably connected to the corresponding bearing seats 70. The second driven crank arm 120 is connected to a second support arm 140 at one end away from the transmission shaft 100 and is connected to the pallet 40. After the steel pipe completes the corresponding work on the steel pipe lifting assembly 10, the cylinder 50 drives the active crank arm 80 to rotate. The active crank arm 80 drives the connecting shaft 20 to rotate. At the same time, the connecting shaft 20 drives the first driven crank arm 90 to rotate, and the first driven crank arm 90 drives the transmission shaft 100 to move, thereby driving the second driven crank arm 120 to rotate. This allows the steel pipe on the pallet 40 to be lifted synchronously and smoothly under the action of the active crank arm 80, the first driven crank arm 90, and the second driven crank arm 120.

[0026] The top of the pallet 40 is provided with a first platform 150 and a second platform 160 on both sides. Both the first platform 150 and the second platform 160 are used to place steel pipes.

The first platform 150 and the second platform 160 are used to restrict the rolling of the steel pipes.

[0027] The top of the first platform 150 is an inclined first slope, and the top of the second platform 160 is an inclined second slope. The first slope forms a first angle 190 with the first stop 170, and the second slope forms a second angle 200 with the second stop 180. When the pallet 40 is lifted, the steel pipe is placed at the corresponding first angle 190 and second angle 200 to prevent the steel pipe from shaking during the lifting process.

[0028] A pad 210 is connected to the top of the pallet 40 to prevent wear between the steel pipe and the pallet 40.

[0029] The pad 210 is made of polyurethane, which has good elasticity and resilience, as well as good wear resistance.

[0030] The top ends of the first support arm 110 and the second support arm 140 are each connected to a connecting block 220. The top end of the connecting block 220 is connected to the tray 40. The connecting block 220 is used to indirectly increase the connection area between the first support arm 110 and the second support arm 140 and the tray 40.

[0031] Both sides of the first support arm 110 and the second support arm 140 are provided with reinforcing plates 230 to improve the structural stability of the first support arm 110 and the second support arm 140.

[0032] The platform 30 is connected to a cylinder seat 240, and the cylinder 50 is placed on the top of the cylinder seat 240.
