Detailed Description

The utility model provides a steel pipe lifting appliance, and in order to make the purpose, technical scheme and effect of the utility model clearer and clearer, the utility model is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in figures 1 and 2, the utility model provides a steel pipe lifting appliance, which comprises a lifting frame 1, swing arms 7 symmetrically arranged at two sides of the lifting frame 1, a driving mechanism 10 for driving the swing arms 7 to swing, and a transmission mechanism connected with the driving mechanism 10.

Specifically, the hanger 1 may be connected to a hook of a crane (not shown in the drawings), and the crane may be operated by remote control to lift and lower the steel pipe hanger during operation, so as to facilitate steel pipe handling.

As shown in fig. 1 and 3, in particular, the hanger 1 includes two parallel hanging beams 2; and hanging rods 3 are arranged above the two hanging beams 2 in a crossing manner. The hanging rod 3 is used for installing the swing arm 7, when the driving mechanism 10 works, the swing arm 7 can swing between the two hanging beams 2, and the hanging beams 2 cannot be touched in the swinging process, so that the steel pipe can be smoothly carried by the steel pipe lifting appliance.

As shown in fig. 2 and 4, in particular, the transmission mechanism includes a rotating rod 11 and two connecting rods 12; the axial direction of the rotating rod 11 is vertical to the length direction of the hanging beams 2, and the rotating rod 11 is rotatably arranged between the hanging beams 2 and can be directly driven by the driving mechanism 10; one end of each connecting rod 12 is hinged to the rotating rod 11, and the other end of each connecting rod is hinged to the two swing arms 7.

When the driving mechanism 10 drives the rotating rod 11 to rotate, one rod of the two connecting rods 12 moves downwards, the other rod moves upwards, the connecting rod 12 moving downwards can pull the swing arm 7 to swing anticlockwise and the connecting rod 12 moving upwards can push the swing arm 7 to rotate clockwise in order to maintain the hinged relation with the swing arm 7, and therefore the opening or closing operation of the swing arm 7 can be achieved through the two connecting rods 12 with different moving directions.

As shown in fig. 1 and 2, specifically, a hanging plate 8 is disposed at a free end of the swing arm 7, and a supporting surface 9 matched with an inner wall of the steel pipe is disposed on the hanging plate 8. When carrying the steel pipe, swing arm 7 is in the state of foling, and link plate 8 is located inside the steel pipe and passes through holding surface 9 bears the steel pipe, has ensured that the steel pipe keeps balanced and can not drop from between swing arm 7 in handling, has promoted the security of operation.

The working of the utility model is further explained below:

when a steel pipe needs to be carried, the steel pipe lifting appliance is moved to the position of the steel pipe to be carried through the crane, the steel pipe is positioned between the two swing arms 7, and at the moment, an operator remotely controls the driving mechanism 10 to enable the two swing arms 7 to swing simultaneously and enable the swing arms 7 to be gradually folded; and the swing arm 7 is in the in-process of foling, and link plate 8 enters into inside the steel pipe to when swing arm 7 swung to the direction perpendicular to the steel pipe axial, swing arm 7 no longer continued to foling, at this moment, hoist lifting sling upwards made link plate 8 upwards remove to make holding surface 9 and steel pipe inner wall contact, after guaranteeing that the steel pipe is supported, rethread hoist removal steel pipe hoist, alright realize the transport of steel pipe.

As shown in fig. 2, further, the driving mechanism 10 is an electric push rod, and the electric push rod is fixedly arranged between the suspension beams 2; the transmission mechanism further comprises a swinging piece 15 arranged on the rotating rod 11, and the free end of the swinging piece 15 is hinged to the free end of the electric push rod. When the electric push rod works, the electric push rod can push the swinging piece 15 along the length direction of the hanging beam 2, and the free end of the swinging piece 15 is movably hinged to the free end of the electric push rod, so when the electric push rod pushes the swinging piece 15, the swinging piece 15 can swing and can drive the rotating rod 11 to rotate.

Of course, the driving mechanism 10 may also be an air cylinder, and the swinging of the swinging member 15 can also be realized by additionally installing a connecting member suitable for the movable hinge joint of the swinging member 15 at the extending end of the piston rod of the air cylinder.

As shown in fig. 2, further, a bearing seat 17 for fixing an end of the hanging rod 3 is arranged on the hanging beam 2, first reinforcing plates 18 are arranged on two sides of the bearing seat 17, the first reinforcing plates 18 are symmetrically arranged on two sides of the bearing seat 17 along an axial direction of the bearing seat 17, and two ends of the hanging rod 3 are respectively inserted into the bearing seat 17.

Because the weight of the steel pipe is large, when the hanger carries the steel pipe, the swing arm 7 and the hanging rod 3 need to bear large weight, so that the hanging rod 3 can bear large weight through the bearing seat 17 and the first reinforcing plate 18, and the condition that the hanging beam 2 is crushed is avoided.

As shown in fig. 1 and 3, further, the hanger 1 further comprises a hanger; the hanging rack comprises a hanging plate 5 and side plates 4 arranged on two sides of the hanging plate 5; the side plates 4 are respectively fixed on the hanging beam 2, the hanging plate 5 is provided with hanging holes 16 along the length direction of the hanging beam 2, and the hanging holes 16 are hooked by a lifting hook of the crane, so that the crane can lift the whole hanging frame 1.

As shown in fig. 3, two second reinforcing plates 14 are symmetrically arranged on each side plate 4, and the second reinforcing plates 14 are respectively connected with two surfaces of the hanger plate 5. The second reinforcing plate 14 is used for improving the structural strength of the hanger and the bearing capacity of the hanger 1.

As shown in fig. 3, further, the hanger further comprises two longitudinal beams 6 arranged between the side plates 4 and connected with the side plates 4; the lower part of the longitudinal beam 6 is connected with two hanging beams 2. The longitudinal beam 6 can enable the hanging rack to be firmly arranged on the hanging beam 2, and further the integral structural strength of the hanging rack 1 is improved.

As shown in fig. 2, a rubber pad 13 is further laid on the supporting surface 9. Because the supporting surface and the side surface of the swing arm 7 intersected with the supporting surface 9 can be contacted with the steel pipe when the steel pipe is conveyed, the condition that the steel pipe is damaged (if a groove occurs) by the suspension arm when the steel pipe is conveyed by the lifting appliance can be avoided by arranging the rubber pad 13.

Further, a storage battery is further placed between the hanging beams and can be electrically connected with the electric push rod for supplying power to the electric push rod, so that the erection of cables is reduced, the steel pipe lifting appliance can be moved more conveniently, and the steel pipes can be conveniently carried.

In summary, the utility model provides a steel pipe lifting appliance, swing arms are symmetrically arranged on two sides of a hanging bracket connected with a crane, and hanging plates are arranged at free ends of the swing arms, so that when a steel pipe is conveyed, the inner wall of the steel pipe can be supported by the hanging plates, the steel pipe cannot fall off in the conveying process, the steel pipe can be conveyed without a steel wire bundling and rolling mode, the steel pipe cannot be damaged, and the quality of the steel pipe is ensured.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
