Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a C-type hook balanced lifting device. Background Art

[0002] The lifting equipment starts a vertical or vertical and horizontal working stroke after picking up the material, unloads after reaching the destination, and then travels empty to the material picking location, completing a working cycle, and then performs a second lifting or transportation. The lifting mechanism of the crane usually uses two lifting ropes to lift the heavy objects, and the two lifting ropes serve to share the load of the heavy objects.

[0003] After searching the publication (announcement) number: CN 215326552 U, a high-balance lifting device for an air conditioner outdoor unit for air conditioner installation is disclosed, including an air conditioner outdoor unit and a connecting buckle, and also including an anti-tilting and shaking balancing lifting mechanism, the top two sides of the air conditioner outdoor unit are fixedly installed with connecting buckles, and the top of the telescopic connecting buckle is movably connected with an anti-tilting and shaking balancing lifting mechanism, and the anti-tilting and shaking balancing lifting mechanism includes a forward and reverse reduction motor, a driving gear turntable, a driven gear turntable, a supporting shaft, a rope drum, an auxiliary bearing, a lifting rope, a fixing plate, a wall support rod and an auxiliary roller, and the driving gear turntable is fixedly connected to the central through hole on one side of the forward and reverse reduction motor through an output shaft. The utility model can achieve high stability when lifting the air conditioner outdoor unit, avoiding the problem of possible shaking back and forth and contact and collision with the wall surface to cause damage or fall of the equipment, and poor safety.

[0004] Although the above scheme avoids the possible back and forth shaking and contact with the wall to cause damage or fall of the equipment, thereby improving safety, it is inconvenient to adjust the distance between the two lifting hooks according to the lifting objects during the lifting process. The unstable center of gravity may cause the lifted materials to tilt, causing the materials to fall, thereby affecting the lifting effect. For this reason, we propose a C-type hook balanced lifting device. Utility Model Content

[0005] The main purpose of the utility model is to provide a C-type hook balanced lifting device, which solves the problem that when the distance between the two lifting hooks is adjusted according to the lifting objects, the lifting center is easily tilted due to unstable gravity center, which causes the materials to fall and affects the lifting effect.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A C-type hook balancing lifting device includes a fixing unit, and further includes a balance adjusting unit arranged below the fixing unit, a lifting unit arranged inside the balance adjusting unit, and a clamping unit arranged below the lifting unit;

[0008] The balance adjusting unit includes a mounting frame installed at the bottom of the fixing unit, a threaded shaft movably arranged inside the mounting frame and having threads with opposite helix directions at both ends, a moving part installed on the circumferential side of the threaded shaft, and a first driving motor installed at the input end of the threaded shaft;

[0009] The lifting unit includes a U-shaped seat installed at the bottom of the moving part, a rotating shaft movably arranged inside the U-shaped seat, a rope winding drum installed on the side wall of the rotating shaft, a second driving motor installed at the input end of the rotating shaft, and a lifting rope wound on the surface of the rope winding drum.

[0010] Preferably, the fixing unit includes a positioning card wall clamp plate, a hydraulic cylinder installed on the side wall of the positioning card wall clamp plate, and a fixing seat installed at the telescopic end of the hydraulic cylinder.

[0011] Preferably, the balance adjusting unit further includes a limit washer installed on the inner side wall of the mounting frame, and the limit washer is sleeved on the circumferential side of the threaded shaft.

[0012] Preferably, the lifting unit further includes a cleaning sleeve installed on the side wall of the U-shaped seat, and the cleaning sleeve is sleeved on the circumferential side of the lifting rope.

[0013] Preferably, the clamping unit includes a C-shaped seat installed at the bottom of the lifting rope, an adjusting part movably arranged inside the C-shaped seat, and a guide post installed on the inner wall of the C-shaped seat and passing through the adjusting part.

[0014] Preferably, the adjusting part includes a threaded hole opened at the top of the C-shaped seat, a threaded rod movably passing through and arranged inside the threaded hole, a movable plate installed at one end of the threaded rod located inside the C-shaped seat, and a screwing handle installed at the top of the threaded rod.

[0015] Preferably, there are two sets of the overall structures composed of the lifting unit and the clamping unit, and the two sets of the overall structures composed of the lifting unit and the clamping unit are symmetrically arranged with respect to the bisecting plane of the threaded shaft.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the present utility model, through the provided balance adjustment unit and the lifting unit, when it is necessary to make the lifting center of gravity located at the middle position between the two lifting hooks according to the material, the first driving motor drives the threaded shaft to rotate. Since the threaded shaft is provided with threads with opposite helix directions at both ends, the two moving parts can drive the two U-shaped seats to move towards each other or away from each other through the lifting unit until the two lifting hooks can adapt to the center of gravity of the material to be lifted and then stop. Thus, the distance between the two lifting hooks is adjusted according to the lifted object, ensuring that the center of gravity of the material is located between the two lifting hooks, avoiding the inclination and dropping of the material, and ensuring the lifting effect. When it is necessary to lift the material, the U-shaped seat is wrapped around the lifting position of the material. Subsequently, the screwing handle is rotated, so that the threaded rod drives the movable plate to move downward, thereby making the movable plate in close contact with the material, and the movable plate and the U-shaped seat complete the clamping and fixing of the position to be lifted. Subsequently, the second driving motor drives the rotating shaft to rotate. At this time, the rope winding drum rotates synchronously with the rotating shaft, and the lifting rope is continuously wound by the rope winding drum, so as to gradually lift the lifting material below the lifting rope, thus realizing the balanced lifting of the material.
