The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.

Referring to fig. 1 to 3, the present invention provides an embodiment of a multi-steel jacket hanger with anti-swing function, which includes a cross beam 1, a clamp 2, a driving assembly 3 and a stabilizer 4. The cross beam 1 is a main body of the sling resisting swinging of a plurality of steel sleeves and is used for being connected with equipment such as a crane and the like to realize lifting. The tongs 2 are slidably connected to both ends of the beam 1, and the driving assembly 3 is connected to the beam 1 and the two tongs 2 for driving the tongs 2 to slide along the extending direction of the beam 1 to clamp both ends of the steel jacket 100. The specific structure of the clamp 2 and the driving assembly 3 will be described in detail later, and will not be described herein. The stabilizer 4 comprises two supporting legs 41, wherein the two supporting legs 41 are both fixedly mounted on the beam 1, are respectively positioned on two sides of the beam 1, and respectively extend towards two sides of the clamped steel sleeve 100. When the two clamps 2 clamp the steel jacket 100, the two support legs 41 are respectively located at two sides of the axis of the steel jacket 100 and are respectively abutted against the circumferential surface of the clamped steel jacket 100.

Referring to fig. 4, the invention provides a swing-resistant multi-steel-sleeve lifting appliance, wherein a driving assembly 3 drives a clamp 2 to clamp two ends of a steel sleeve 100, and a cross beam 1 is lifted by equipment such as a crane, so that the steel sleeve 100 is lifted. The two support legs 41 of the stabilizer 4 can be used as two additional positioning surfaces to abut against two sides of the steel jacket 100 at the same time when the clamp 2 clamps the steel jacket 100, so that the steel jacket 100 can be prevented from swinging towards two sides of the extending direction of the cross beam 1 in the air. In addition, the present embodiment does not limit the size of the steel jacket 100, and only needs to ensure that the two support legs 41 can contact and stabilize the circumferential surface of the steel jacket 100.

The clamp frame 21 is connected with the cross beam 1, the clamp frame 21 and the cross beam 1 in the embodiment both include two plate-shaped structures, for example, the cross beam 1 is assembled by two parallel long plates with intervals through rib plates, bolts or welding, etc. to reduce the weight, and one clamp frame 21 is also mainly composed of two plate-shaped workpieces, which are respectively located on two sides perpendicular to the plate direction of the cross beam 1. The bottom of the pliers frame 21 is a cross bar perpendicular to the plate of the cross beam 1 for connecting the first hook 22, i.e. the second hook 23 and the third hook 24, which will be described later.

The first hook 22 in this embodiment is connected to the pliers frame 21, the first hook 22 is bent toward the inner sides of the two pliers 2, the two first hooks 22 and the cross beam 1 are located in a first plane, and the two support legs 41 are symmetrically arranged along the first plane. The first hooks 22 are the portions actually used for contacting the end face of the steel jacket 100, and can directly clamp the two ends of the steel jacket 100 from both sides, and the bent portions of the first hooks 22 extend into the inner hole of the steel jacket 100, and can be used for supporting the inner wall of the steel jacket 100. When the driving assembly 3 has sufficient driving force, the clamp 2 can be driven, that is, the first hooks 22 firmly clamp the two ends of the steel jacket 100, the hooks are not required to support the inner wall of the steel jacket 100, but the bent portions of the first hooks 22 still can play a positive role in preventing the steel jacket 100 from falling off.

With reference to fig. 2 and the drawings, the present invention also provides a preferred embodiment, the plurality of hooks in the tongs 2 of the sway resisting multi-steel jacket spreader further comprises two second hooks 23 having the same structure as the first hook 22, and the two second hooks 23 are connected to the beam 1 and respectively located on both sides of the first hook 22 in the direction perpendicular to the first plane. The second hook 23 may increase the number of steel jackets 100, for example two or three, that the present anti-sway multi-steel jacket spreader grips at one time. Use two second lifting hooks 23 to press from both sides respectively and get two steel casings 100, two first lifting hooks 22 are out of work for example, when two second lifting hooks 23 gripped a steel casing 100 respectively, two supporting legs 41 can be respectively the butt two steel casings 100, contact between two steel casings 100 in addition for steel casing 100 can receive two locating surface effects equally, even this anti many steel casings hoists of swing press from both sides simultaneously and get two or three steel casings 100 when like this, can prevent the swing equally, improved efficiency.

Referring to fig. 3, as a preferred embodiment, the extending direction of the supporting leg 41 in this embodiment is perpendicular to the extending direction of the beam 1, an abutting acting surface 42 is formed on one side of the supporting leg 41 facing the clamped steel sleeve 100, the abutting acting surface 42 extends along a direction away from the beam 1, the interval between the abutting acting surface 42 and the first plane is gradually increased, that is, a V-shape is formed when viewed from the side, and then the abutting acting surface extends along a direction perpendicular to the first plane. Specifically, the abutting acting surface 42 is sequentially divided into a first abutting surface and a second abutting surface along the direction departing from the beam, the first abutting surface and the beam 1 are overlapped and extend towards one side of the clamped steel sleeve 100, the first abutting surface is obliquely arranged relative to the first plane, the second abutting surface is perpendicular to the first plane, and the first abutting surface and the second abutting surface are parallel to the axis of the clamped steel sleeve 100.

The spacing of the two second hooks 23 is greater than the maximum spacing between the two first abutment surfaces and less than the spacing between the distal ends of the two second abutment surfaces. When only the first hook 22 is used to clamp a steel jacket 100, the two abutment surfaces 42 of the two support legs 41, which are in the shape of a V, can firmly limit the swing of the steel jacket 100. At this moment, if the two second hooks 23 also clamp the steel sleeve 100, that is, when the three steel sleeves 100 are transported in total, the steel sleeves 100 clamped by the second hooks 23 positioned at the two sides of the first hook 22 can lean against the steel sleeve 100 clamped by the first hook 22, so that the steel sleeves 100 are stable and do not swing, and thus, the stabilizing frame 4 for fixing one steel sleeve 100 is only required to be additionally arranged on the cross beam, and the three steel sleeves 100 can be simultaneously stable. Meanwhile, the whole lifting appliance is guaranteed not to have too much complex structure, and the lifting appliance is light in weight and low in cost. And under the condition that the abutting action surface 42 can contact the circumferential surface of the steel sleeve 100, the size of the steel sleeve 100 is not limited, the pipe diameter of the steel sleeve 100 can be random, and the pipe diameters of a plurality of steel sleeves 100 lifted simultaneously can be inconsistent, so that the anti-swing lifting appliance with the plurality of steel sleeves has better applicability.

As a preferred embodiment, the surface of the abutment acting surface 42 in this embodiment is covered with a pad 43. The spacer 43 may be made of polyurethane, nylon, etc. to prevent the steel sleeve 100 from sliding, and may be made of a soft material, such as rubber, to prevent the surface of the steel sleeve 100 from being worn.

Referring to fig. 2, the present invention further provides a preferred embodiment, the tongs 2 of the swing-resistant multi-steel jacket spreader further include at least two third hooks 24, the third hooks 24 are connected to the beam 1 and respectively located at the outer sides of the two second hooks 23, and the first hook 22, the second hook 23 and the third hooks 24 are arranged along a same line perpendicular to the first plane. The third hook 24 is also the same as the first hook 22 in structure, so that the quantity of the steel sleeves 100 of the multi-steel sleeve sling capable of resisting swinging can be further increased. For example, two third lifting hooks 24 are arranged in the embodiment, so that the anti-swing lifting appliance with the plurality of steel sleeves can lift four or five steel pipes at a time, and the pipe diameters of the plurality of steel sleeves can be different. Above all, the steel sleeve 100 gripped by the third hook 24 can lean against the steel sleeve 100 gripped by the second hook 23, and the corresponding steel sleeve of the third hook 24 can be prevented from swinging. Similarly, when a tong 2 is actually provided with six, nine or more hooks, a plurality of steel sleeves can be stabilized.

In addition, the inner sides of the first hook 22, the second hook 23 and the third hook 24 in this embodiment may also be covered with a liner plate to perform the same function as the liner 43, i.e., prevent the hooks from pressing or scratching the end surface of the steel sleeve, reduce the generation of waste materials, and improve the yield rate of products.

Referring to fig. 1 again, as a preferred embodiment, the number of the stabilizing frames 4 in this embodiment is two, and the two stabilizing frames are arranged along the extending direction of the cross beam 1, so as to improve the stabilizing effect, and ensure that the anti-swing multi-steel sleeve sling has a light weight. In practice, a larger number of stabilizing frames 4, such as three, five or eight, may be provided as required.

As a preferred embodiment, the drive assembly 3 in this embodiment comprises a hanger 31 and two tie rods 32. The spreader 31 is located on the side of the beam 1 facing away from the clamped steel jacket 100 for connection to a crane and has a lifting pin for hooking a hook on the crane. The two pull rods 32 respectively correspond to the two clamps 2, one end of each pull rod 32 is rotatably connected to the hanger 31, the other end of each pull rod 32 is rotatably connected to the corresponding clamp 2, and the rotating axes of the two ends of each pull rod 32 are perpendicular to the corresponding pull rod 32.

The above-mentioned mode is a mechanical drive, when the crane lifts the hanger 31, the two pull rods 32 will be drawn by the weight of the beam 1 and will be used as arm to drive the clamp 2 to clamp the two ends of the steel sleeve 100. In order to improve the clamping force, the length of the pull rod 32 can be increased optionally, and the structure does not need to be connected with an additional power source, so that the whole anti-swing multi-steel-sleeve lifting appliance is simpler and easier to use. It is easy to understand that other devices may be used to drive the two clamp jaws 2 to fold, for example, a hydraulic cylinder capable of extending and retracting along a straight line is used as the driving component 3, and two ends of the hydraulic cylinder are respectively connected to the two clamp jaws 2, and can also drive the clamp jaws 2 to fold or separate.

Referring to fig. 1 and 5, as a preferred embodiment, a cross beam 1 of the sway resisting multi-steel jacket hanger in this embodiment is provided with a kidney-shaped hole-shaped slideway 11, the tongs 2 further includes two sliding shafts 25, both sliding shafts 25 pass through the slideway 11, and one sliding shaft 25 also passes through one end of the pull rod 32 away from the hanger 31. Similar to the cross member 1 and the pliers frame 21, the tie bar 32 is also formed by two long flat and parallel rods to reduce the weight of the whole device. As can be seen, the tie rods 32 in this embodiment are located between the two sheets that make up the beam 1.

The sliding shaft 25 functions as a slide for ensuring that the clamp 2 can slide linearly along the slide 11, in addition to the hinge connection with the pull rod 32. The sliding shaft 25 can be sleeved with a roller sleeve, and parts such as an oil cup and the like can be installed to ensure lubrication. In the embodiment, one clamp 2 comprises two sliding shafts 25, and the two sliding shafts 25 are simultaneously inserted into one slideway 11, so that the clamp 2 can be prevented from rotating, and the clamp 2 can always move along the direction parallel to the axis of the steel sleeve and clamp the steel sleeve 100.

The invention also provides a preferred embodiment, as shown in fig. 6, wherein the driving assembly 3 in the anti-swing multi-steel sleeve sling further comprises a sliding sleeve 33 and a sliding rod 34. Wherein one end of the sliding sleeve 33 is fixedly connected to the hanger 31, and the other end of the sliding sleeve 33 faces the beam 1. Two protrusions are symmetrically formed on the outer peripheral surface of the sliding sleeve 33 and are used for hinging with one ends of the two pull rods 32, which are far away from the clamp 2, namely, the pull rods 32 in the embodiment are connected with the hanger 31 through the sliding sleeve 33. One end of the sliding rod 34 is vertically and fixedly connected with the middle part of the cross beam 1, and the other end of the sliding rod 34 is slidably inserted in the sliding sleeve 33. When the two pull rods 32 are closed or expanded, the sliding rod 34 can be extended or retracted in the sliding sleeve 33. At the moment, the sliding rod 34 and the sliding sleeve 33 can enable the two clamps 2 to synchronously move, namely the displacement is consistent, so that the center of gravity of the whole anti-swing multiple steel sleeve lifting appliance is always kept at one position, the deflection is prevented, and the stability is improved.

As a preferred embodiment, the anti-swing multi-steel sleeve hanger of the present embodiment further comprises a shutter 5, and both ends of the shutter 5 are respectively connected to the sliding sleeve 33 and the cross beam 1. Specifically, the fixed end is fixedly connected with the sliding sleeve 33, and the contact is movably connected with the beam 1. The shutter 5 is a common locking part in the field of the clamp 2 lifting appliance, and taking this embodiment as an example, when the contact of the shutter 5 is clamped with the beam 1, the shutter 5 can be connected with the beam 1 and the sliding sleeve 33 to prevent the two from separating, and thus, the two clamps 2 are ensured to be in an expanded state. When the hanger is used, the stabilizing frame 4 touches the workpiece, so that the contact of the shutter 5 moves and further breaks away from the beam 1, and at the moment, along with the rising of the hanger 31 and the sliding sleeve 33, the gravity of the beam 1 can enable the two pull rods 32 to be folded, so that the clamp 2 can be folded and clamp the steel sleeve. The same applies when lowering the steel jacket, except that the change of state of the entire anti-sway multi-steel jacket spreader is reversed from the process described above.

The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same or similar parts among the embodiments are referred to each other.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
