Description

Technical Field

[0001] The invention relates to the technical field of cranes, and in particular to a convenient parts transport and hoisting device. Background Art

[0002] Portable hoist is a small mechanical equipment with excellent performance and extremely wide application. It is suitable for hoisting operations in high-rise buildings, such as the hoisting of various building materials and various decoration materials, especially for long and wide materials such as wooden boards and woodworking boards that are inconvenient to carry in corridors. At the same time, it can also be used for lifting large workpieces on and off machine tools in mechanical processing workshops, home appliance factories, food factory production assembly lines, warehouses, and household lifting items.

[0003] A Chinese patent with announcement number CN203173709U discloses a vehicle-mounted small crane, which includes a base, a column welded to the upper end of the base, a support frame, and a lifting device fixed on the support frame. A connecting rod is provided at the top of the column; the support frame is fixed to the connecting rod through a bearing; the support frame is provided with a positioning top screw that enables the support frame to rotate 360°; the positioning top screw is a short handle in the shape of a curved handle. This equipment is installed on a vehicle and is easy to use. The short handle positioning top screw fixed on the support frame has changed the previous straight arm long handle straight rod shape, saving materials and reducing production costs. The support frame is provided with three positioning holes for fixing the positioning top screw. Users can install the positioning top screw according to actual needs. It is easy to operate, has a compact structure, a small size, and occupies a small space. It is an ideal choice for lifting fewer objects.

[0004] With respect to the above-mentioned related technologies, in the prior art, the operator utilizes the cooperation of the first bearing, the second bearing and the positioning screw to realize lifting parts on a circular path line with the boom as the radius. Although the crane in the prior art also adjusts the length of the boom through the cooperation of the boom and the boom to increase the lifting range, this requires limiting the position of the boom through the adjustment hole in advance. Therefore, in the actual lifting process, the crane can only be lifted along a circular path with the boom length as the radius. In this way, the lifting range of the crane is small, which reduces the applicability of the crane. Summary of the invention

[0005] In order to improve the applicability of the lifting device, the present application provides a convenient parts transfer lifting device.

[0006] The present application provides a convenient parts transfer and lifting device using the following technical solutions: A convenient parts transport and lifting device comprises a support column, on which a rotating frame and a rotating assembly for driving the rotating frame to rotate are arranged, the rotating frame is rotatably connected to a rotating beam, a rope-releasing machine is installed on the rotating frame, a lifting rope is installed on the rope-releasing machine, the lifting rope is wound around the rotating beam, and one end of the lifting rope is sequentially connected to a controller, an operating handle and a hook, and the rope-releasing machine is electrically connected to the controller.

[0007] By adopting the above technical solution, when lifting parts, the operator starts the rope release machine through the controller to lower the hook to lift the parts, and then moves the hook to the specified position through the operating handle. During this process, the rotating beam rotates to achieve the effect of transporting parts. The operator uses the rotatable rotating beam to lift the parts to the circular area with the sum of the rotating beam and the rotating frame as the radius without adjusting the length of the rotating frame and the rotating beam. In this way, with the rotating assembly and the rotating frame, the parts can be lifted to as many positions as possible within the above circular range. Compared with the existing technology, the lifting range of the parts is increased and the applicability of the lifting device is improved.

[0008] Optionally, a restoring assembly is provided on the rotating beam, and the restoring assembly includes a reset spring and a limiting roller. The rotating beam and the controller are both connected with limiting cylinders. The reset spring is sleeved on the suspension rope and connected between two limiting cylinders. A mounting frame is connected to the rotating beam, and two limiting rollers are rotatably connected on the mounting frame. A gap is left between the two limiting rollers, and the suspension rope passes between the two limiting rollers.

[0009] By adopting the above technical solution, when the operator moves the operating handle to rotate the rotating beam, the lifting rope is restricted by the restriction tube and bent, so that the hook rises and the restoring spring is compressed. After the parts are lowered and the operating handle is released, the hook is lowered by the force of the restoring spring. In this way, the lifting rope is in a stretched state, and the bent rope is restored to a straight rope, thereby driving the rotating beam to rotate in the opposite direction, thereby achieving the effect of restoring the hook to its initial position.

[0010] Optionally, the rotating assembly includes a rotating motor, a rotating roller, a connecting ring and a transmission belt. The rotating frame is connected to the connecting frame, the rotating motor is installed on the connecting frame, the rotating roller is rotatably connected to two on the connecting frame, a rubber layer is provided on the surface of the rotating roller, the transmission belt is sleeved between the output shaft of the rotating motor and the two rotating rollers, the connecting ring is connected to the support column at a position corresponding to the rotating roller, a frosted layer is provided on the surface of the connecting ring, and the rotating roller contacts the connecting ring.

[0011] By adopting the above technical solution, when driving the rotating frame to rotate, the operator starts the rotating motor through the controller, and drives the two rotating rollers to rotate synchronously through the transmission belt. The friction between the rubber layer and the frosted layer achieves the effect of driving the rotating frame to rotate.

[0012] Optionally, a fixed cylinder is connected to the rotating frame, a rotating shaft is connected to one end of the rotating beam, the rotating shaft is rotatably connected in the fixed cylinder, and a limiting component for limiting the rotation of the rotating beam is provided on the rotating beam.

[0013] By adopting the above technical solution, when the parts are hoisted to the designated position, a clamping means for limiting the parts needs to be prepared at the designated position, so that the parts are limited to the designated position, which is conducive to the operator to install the parts. After the operator transports the parts to the designated position, the limiting component is used to limit the angle of the rotating beam, thereby achieving the effect of limiting the movement of the parts and providing convenience for the installation of the parts.

[0014] Optionally, the limiting assembly includes an electric push rod, a fixed ring, a movable ring and a connecting flange, the fixed ring is connected to the rotating shaft, the rotating shaft passes through the fixed ring, the movable ring is slidably fitted in the fixed cylinder and is sleeved on the rotating shaft, the movable ring and the fixed ring are coaxially arranged, the electric push rod is installed in the rotating frame, the electric push rod is electrically connected to the controller, a connecting rod is connected between the output shaft of the electric push rod and the movable ring, the fixed cylinder has an avoidance groove at a position corresponding to the connecting rod, several connecting flanges are connected to the movable ring, the connecting flanges are arranged in a truncated cone shape, and the larger end of the connecting flange is connected to the movable ring, the fixed ring has a plurality of limiting holes matching the shape of the connecting flange, the connecting flange corresponds to the limiting holes one by one, and when limiting the rotating beam, the connecting flange is located in the limiting hole.

[0015] By adopting the above technical solution, when limiting the rotation of the rotating beam, the operator starts the electric push rod through the controller to lower the movable ring, thereby driving the connecting flange to lower until the connecting flange enters the limiting hole. By limiting the cooperation between the limiting flange and the limiting hole, the rotation of the rotating shaft is limited, thereby achieving the effect of limiting the rotation of the rotating beam.

[0016] Optionally, a plurality of sliding bars are connected to the inner wall of the fixed cylinder, and a plurality of sliding grooves are opened on the movable ring, and the sliding grooves are slidably matched with the sliding bars.

[0017] By adopting the above technical solution, the operator uses the sliding bar to limit the moving direction of the moving ring. On the one hand, it reduces the possibility of the moving ring being offset during movement, keeps the connecting flange in a vertical state, and enables the connecting flange to better enter the limiting hole. On the other hand, it reduces the possibility of the moving ring being deflected due to force, thereby improving the stability of limiting the rotation of the rotating shaft.

[0018] Optionally, the limiting assembly includes a hydraulic press and a limiting ring, a supporting ring is connected to the inner wall of the fixed cylinder, the limiting ring is sleeved on the rotating shaft and connected to the supporting ring, a hydraulic chamber is opened in the limiting ring, the inner ring wall and the outer ring wall of the limiting ring are both set to be thin walls, the hydraulic press is installed in the rotating frame, an oil pipeline is connected between the hydraulic press and the inside of the limiting ring, and the hydraulic press is electrically connected to the controller.

[0019] By adopting the above technical solution, when limiting the rotation of the rotating beam, the operator starts the hydraulic press through the controller to allow hydraulic oil to enter the hydraulic chamber. As the pressure in the hydraulic chamber increases, the inner and outer walls of the limiting ring are deformed, and the inner wall presses against the rotating shaft, and the outer wall presses against the inner wall of the fixed cylinder. The friction between the inner wall and the rotating shaft and the friction between the outer wall and the inner wall of the fixed cylinder limits the rotation of the rotating shaft, thereby achieving the effect of limiting the rotation of the rotating beam.

[0020] Optionally, the inner wall of the fixed cylinder and the surface of the rotating shaft are both connected with a plurality of strip grooves.

[0021] By adopting the above technical solution, the inner ring wall of the restriction ring rubs against the rotating shaft, and the outer ring wall rubs against the fixed cylinder, which inevitably causes wear. In this way, fine metal residues will be generated between the inner ring wall of the restriction ring and the rotating shaft and between the outer ring wall and the fixed cylinder. If the metal residues cannot be discharged smoothly, the inner ring wall and the outer ring wall of the restriction ring are easily damaged, and the restriction capacity of the restriction ring will be reduced. The operator sets strip grooves on the inner wall of the restriction ring and the surface of the rotating shaft so that the metal residues enter the strip grooves during rotation, thereby reducing the impact on the restriction ring, extending the service life of the restriction ring, and improving the restriction capacity of the restriction ring.

[0022] Optionally, a plurality of stress rollers are connected to the end of the rotating beam, the plurality of stress rollers are vertically distributed in two rows, and are staggered between two adjacent stress rollers, and the suspension rope is a steel wire rope, and the suspension rope passes between the two rows of stress rollers.

[0023] By adopting the above technical solution, when lifting parts, the lifting rope plays the role of bearing the weight of the parts. After long-term use, stress will be generated in the force-bearing parts of the lifting rope, which will cause the lifting rope to deform, reduce the toughness of the lifting rope, and easily cause the lifting rope to fork and break, thereby reducing the service life of the lifting rope. The operator sets up interlaced stress rollers to deform the lifting rope and remove as much internal stress of the lifting rope as possible, so that the lifting rope can be used for a long time, thereby extending the service life of the lifting rope.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When lifting parts, the operator starts the rope release machine through the controller to lower the hook to lift the parts, and then moves the hook to the specified position through the operating handle. During this process, the rotating beam rotates to achieve the effect of transporting parts. The operator uses the rotatable rotating beam to lift the parts to the circular area with the sum of the rotating beam and the rotating frame as the radius without adjusting the length of the rotating frame and the rotating beam. In this way, with the rotating assembly and the rotating frame, the parts can be lifted to as many positions as possible within the above-mentioned circular range. Compared with the existing technology, the lifting range of the parts is increased and the applicability of the lifting device is improved; 2. When the operator moves the operating handle to rotate the rotating beam, the lifting rope is restricted by the restriction cylinder and bent, so that the hook rises and the restoring spring is compressed. After the parts are put down and the operating handle is released, the hook is lowered by the force of the restoring spring. In this way, the lifting rope is in a stretched state, and the bent rope is restored to a straight rope, thereby driving the rotating beam to rotate in the opposite direction, achieving the effect of restoring the hook to its initial position; 3. When the rotation of the rotating beam is limited, the operator starts the electric push rod through the controller to lower the moving ring, driving the connecting flange to lower until the connecting flange enters the limiting hole. The rotation of the rotating shaft is limited by the cooperation between the limiting flange and the limiting hole, thus achieving the effect of limiting the rotation of the rotating beam; 4. When limiting the rotation of the rotating beam, the operator starts the hydraulic press through the controller to allow the hydraulic oil to enter the hydraulic chamber. As the pressure in the hydraulic chamber increases, the inner and outer annular walls of the limiting cylinder are deformed, and the inner annular wall presses against the rotating shaft, and the outer annular wall presses against the inner wall of the fixed cylinder. The friction between the inner annular wall and the rotating shaft and the friction between the outer annular wall and the inner wall of the fixed cylinder limits the rotation of the rotating shaft, thereby achieving the effect of limiting the rotation of the rotating beam.

[0031] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0032] Embodiment 1 of the present application discloses a convenient parts transport and lifting device. Figure 1 The portable parts transport and lifting device comprises a support column 1, and the top of the support column 1 is rotatably connected with a rotating frame 11. A rope release machine 12 is installed at one end of the rotating frame 11, and the rope release machine 12 is a winch.

[0033] Reference Figure 1 and Figure 2 The other end of the rotating frame 11 is fixedly connected to a fixed cylinder 111, and the other end of the rotating frame 11 is provided with a rotating beam 13, one end of the rotating beam 13 is connected to a rotating shaft 131 through a bolt, and the rotating shaft 131 is connected to the fixed cylinder 111 through a bearing. A suspension rope 2 is provided in the rope release machine 12, and the suspension rope 2 is a steel wire rope. The suspension rope 2 is wound around the other end of the rotating beam 13, and the ends of the suspension rope 2 are sequentially provided with a controller 21, an operating handle 22 and a hook 23, and the rope release machine 12 is electrically connected to the controller 21.

[0034] Reference Figure 1 and Figure 3 A plurality of stress rollers 132 are rotatably connected to the rotating beam 13, and the plurality of stress rollers 132 are vertically distributed in two rows, and two adjacent stress rollers 132 are staggered, and the suspension rope 2 passes between the two rows of stress rollers 132. The stress rollers 132 are used to eliminate the internal stress of the suspension rope 2 as much as possible.

[0035] Reference Figure 1 , a restoring assembly 3 is provided on the rotating beam 13, and the restoring assembly 3 includes a reset spring 31 and a limiting roller 32. The ends of the rotating beam 13 and the controller 21 are fixedly connected with limiting cylinders, and the two limiting cylinders are arranged opposite to each other. The reset spring 31 is sleeved on the suspension rope 2 and fixedly connected between the two limiting cylinders. A mounting frame is connected to the rotating beam 13 at a position close to the rotating shaft 131 by bolts, and the limiting rollers 32 are rotatably connected on the mounting frame, and a gap is left between the two limiting rollers 32, and the suspension rope 2 passes between the two limiting rollers 32.

[0036] When the operator moves the operating handle 22 to rotate the rotating beam 13, the rope 2 is restricted by the restriction tube and bent, so that the hook 23 rises and the restoring spring is compressed. After the parts are put down and the operating handle 22 is released, the hook 23 is lowered by the force of the restoring spring, so that the rope 2 is in a stretched state. The rope 2 is restored from the bent state to the straight state, which in turn drives the rotating beam 13 to rotate in the opposite direction, thereby achieving the effect of restoring the hook 23 to its initial position.

[0037] Reference Figure 1 and Figure 2 , a limiting assembly 4 is provided on the rotating beam 13, and the limiting assembly 4 includes an electric push rod 41, a fixed ring 42, a moving ring 43 and a connecting flange 44. The fixed ring 42 is sleeved on the rotating shaft 131 and fixedly connected to the rotating shaft 131. A plurality of sliding bars 112 are fixedly connected to the inner wall of the fixed cylinder 111, and a sliding groove is provided at the position of the moving ring 43 corresponding to the sliding bar 112, and the moving ring 43 slides with the sliding bar 112 through the sliding groove. The cooperation between the sliding bar 112 and the sliding groove is used to improve the stability of the moving ring 43. The moving ring 43 is sleeved on the rotating shaft 131. The electric push rod 41 is installed inside the rotating beam 13 and is electrically connected to the controller 21. A connecting rod is welded between the output shaft of the electric push rod 41 and the moving ring 43, and an avoidance groove is provided at the position of the fixed cylinder 111 corresponding to the connecting rod.

[0038] Reference Figure 2 A plurality of connecting flanges 44 are provided on the side wall of the moving ring 43 near the fixed ring 42. The connecting flanges 44 are provided in a truncated cone shape, and the larger end of the connecting flanges 44 is fixedly connected to the moving ring 43. The fixed ring 42 is provided with a plurality of limiting holes matching the outer shape of the connecting flanges 44, and the connecting flanges 44 correspond to the limiting holes one by one.

[0039] When limiting the rotation of the rotating beam 13, the operator starts the electric push rod 41 through the controller 21, causing the moving ring 43 to descend, driving the connecting flange 44 to descend and enter the limiting hole, thereby limiting the angle of the rotating beam 13 in turn, thereby achieving the effect of limiting the rotation of the rotating beam 13.

[0040] Reference Figure 1 and Figure 4, a rotating assembly 5 is provided on the support column 1, and the rotating assembly 5 includes a rotating motor 51, a rotating roller 52, a connecting ring 53 and a transmission belt 54. A connecting frame is fixedly connected to the rotating frame 11, and the rotating motor 51 is installed on the connecting frame and is electrically connected to the controller 21. The rotating roller 52 is rotatably connected to the two on the connecting frame, and a rubber layer is provided on the surface of the rotating roller 52. The transmission belt 54 is sleeved between the output shaft of the rotating motor 51 and the rotating roller 52. The connecting ring 53 is fixedly connected to the position of the supporting column 1 corresponding to the rotating roller 52, and a frosted layer is provided on the surface of the connecting ring 53, and the rotating roller 52 contacts the fixed ring 42.

[0041] When the rotating frame 11 is driven to rotate, the operator starts the rotating motor 51 through the controller 21 to rotate the rotating roller 52. The rotating frame 11 is driven to rotate through the friction between the rubber layer and the frosted layer.

[0042] The implementation principle of a convenient parts transfer and lifting device in Example 1 of the present application is as follows: when lifting parts, the operator starts the rotating motor 51 through the controller 21 to rotate the rotating roller 52, driving the rotating frame 11 to rotate to a specified angle, and then starts the rope release machine 12 to lower the hook 23 to lift the parts, and then moves the operating handle 22 to drive the parts to move, the rotating beam 13 rotates, and the rope 2 is bent by the restriction roller 32. At this time, the hook 23 rises, the restoring spring is compressed, and the electric push rod 41 is started to drive the moving ring 43 to descend, so that the connecting flange 44 enters the limiting hole to limit the rotating beam 13, and then the parts are put down and the limiting component 4 and the operating handle 22 are released. The hook 23 is lowered by the force of the restoring spring, the rope 2 is straightened, and the rotating beam 13 is driven back to a state flush with the rotating frame 11 to restore the position of the hook 23, thereby achieving the effect of lifting parts.

[0043] The operator uses the rotatable rotating beam 13 to lift the parts into a circular area with the sum of the rotating beam 13 and the rotating frame 11 as the radius without adjusting the length of the rotating frame 11 and the rotating beam 13. In this way, with the cooperation of the rotating assembly 5 and the rotating frame 11, the parts can be lifted to as many positions as possible within the above-mentioned circular range. Compared with the prior art, the lifting range of the parts is increased and the applicability of the lifting device is improved.

[0044] Embodiment 2: The difference between this embodiment and embodiment 1 is that the structure of the limiting component 4 is different.

[0045] Reference Figure 1 and Figure 5The limiting assembly 4 includes a hydraulic press 45 and a limiting ring 46. A supporting ring is fixedly connected to the inner wall of the fixed cylinder 111, and the limiting ring 46 is sleeved on the rotating shaft 131 and fixedly connected to the supporting ring. A hydraulic cavity 461 is provided in the limiting ring 46, and the inner and outer ring walls of the limiting ring 46 are both thin-walled. The hydraulic press 45 is installed in the rotating frame 11, and an oil pipeline is connected between the hydraulic press 45 and the hydraulic cavity 461.

[0046] Reference Figure 5 In order to reduce the metal residue on the inner and outer wall surfaces of the limiting ring 46, a plurality of strip grooves 6 are provided on the inner wall of the fixed cylinder 111 and the surface of the rotating shaft 131. The strip grooves 6 are used to store the metal residue.

[0047] When limiting the rotating beam 13, the operator starts the hydraulic press 45 through the controller 21 to allow the hydraulic oil to enter the hydraulic chamber 461. As the internal pressure of the hydraulic chamber 461 increases, the inner and outer ring walls of the limiting ring 46 are deformed, the inner ring wall presses against the rotating shaft 131, and the outer ring wall presses against the fixed cylinder 111, thereby achieving the effect of limiting the rotating beam 13.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
