Detailed Description

The following detailed description of preferred embodiments of the utility model is made in connection with the accompanying drawings, which form a part hereof, and together with the description of the embodiments of the utility model, are used to explain the principles of the utility model and are not intended to limit the scope of the utility model.

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

In combination with the illustration of fig. 4, the utility model provides an anti-swing multi-steel-sleeve lifting appliance, which drives clamps 2 to clamp two ends of a steel sleeve 100 through a driving assembly 3, and lifts a beam 1 through equipment such as a crane to realize lifting of the steel sleeve 100. While the clamp 2 holds the steel sleeve 100, the two supporting legs 41 in the stabilizer 4 can be used as two additional positioning surfaces to abut against two sides on the peripheral surface of the steel sleeve 100, so that the steel sleeve 100 can be prevented from swinging in the air to two sides in the extending direction of the cross beam 1. Moreover, the present embodiment does not limit the size of the steel sleeve 100, and only needs to ensure that the two support legs 41 can contact and stabilize the circumferential surface of the steel sleeve 100.

As a preferred embodiment, the clamp 2 in this embodiment includes a clamp frame 21 and a plurality of hooks, wherein a middle one of the plurality of hooks is a first hook 22. The clamping frame 21 is connected with the beam 1, and the clamping frame 21 and the beam 1 in this embodiment each comprise two plate-shaped structures, for example, the beam 1 is assembled by two parallel long plates with intervals through rib plates, bolts or welding, so as to reduce weight, and one clamping frame 21 is mainly composed of two plate-shaped workpieces, which are respectively positioned at two sides perpendicular to the plate direction of the beam 1. The bottom of the jaw 21 is a cross bar perpendicular to the plate of the cross beam 1, and is used for connecting a first hook 22, namely a second hook 23 and a third hook 24 which will be described later.

The first hooks 22 in this embodiment are connected to the jaw frame 21, the first hooks 22 are bent toward the inner sides of the two jaws 2, the two first hooks 22 and the cross beam 1 are located in a first plane, and the two supporting legs 41 are symmetrically arranged along the first plane. The first hook 22, i.e. the portion actually used for contacting the end face of the steel sleeve 100, can directly clamp the two ends of the steel sleeve 100 from two sides, and the bent portion of the first hook 22 extends into the inner hole of the steel sleeve 100 and can be used for supporting the inner wall of the steel sleeve 100. When the driving assembly 3 has enough driving force to drive the clamp 2, that is, the first lifting hook 22 firmly clamps the two ends of the steel sleeve 100, the lifting hook is not required to support the inner wall of the steel sleeve 100, but the bending part of the first lifting hook 22 still has the positive effect of preventing the steel sleeve 100 from falling off.

In connection with fig. 2 and shown, the present utility model also provides a preferred embodiment, wherein the plurality of hooks in the clamp 2 of the anti-swing multiple steel sleeve lifting tool further comprises two second hooks 23 with the same structure as the first hooks 22, and the two second hooks 23 are connected to the cross beam 1 and are respectively located at two sides of the first hooks 22 along the direction perpendicular to the first plane. The second lifting hook 23 can increase the number of steel jackets 100 which are clamped by the anti-swing multiple steel jacket lifting tool at one time, for example, two or three. Taking two steel sleeves 100 are respectively clamped by using two second lifting hooks 23, two first lifting hooks 22 do not work as an example, when one steel sleeve 100 is respectively clamped by two second lifting hooks 23, two supporting legs 41 can respectively abut against two steel sleeves 100, and in addition, the two steel sleeves 100 are contacted, so that the steel sleeves 100 can be subjected to the action of two positioning surfaces, and thus, even if the swing-resistant multiple steel sleeve lifting tool clamps two or three steel sleeves 100 at the same time, swing can be prevented, and the efficiency is improved.

Referring to fig. 3 again, as a preferred embodiment, the extending direction of the supporting leg 41 is perpendicular to the extending direction of the beam 1, the side of the supporting leg 41 facing the clamped steel sleeve 100 is formed with an abutment surface 42, and the abutment surface 42 extends in a direction away from the beam 1, and the distance from the first plane gradually increases, i.e. a V-shape is formed when seen from the side, and then extends in a direction perpendicular to the first plane. Specifically, the abutment surface 42 is sequentially divided into a first abutment surface and a second abutment surface along a direction away from the cross beam, the first abutment surface is overlapped with the cross beam 1 and extends toward one side of the clamped steel sleeve 100, the first abutment surface is obliquely arranged relative to the first plane, the second abutment surface is perpendicular to the first plane, and the first abutment surface and the second abutment surface are both 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 one steel bushing 100 is clamped by the first lifting hook 22, the two abutting action surfaces 42 with V-shaped shapes on the two supporting legs 41 can firmly limit the swing of the steel bushing 100. If the two second hooks 23 also hold the steel sleeves 100 at this time, that is, when three steel sleeves 100 are assembled together, the steel sleeves 100 held by the second hooks 23 located at both sides of the first hooks 22 can lean against the steel sleeves 100 held by the first hooks 22, so that stable and non-swinging can be realized, and thus, the three steel sleeves 100 can be stabilized at the same time only by additionally installing the stabilizing frame 4 for fixing one steel sleeve 100 on the cross beam. Meanwhile, the whole lifting appliance is ensured not to have excessive complex structures, 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 peripheral 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 swing-resistant multi-steel-sleeve lifting tool has better applicability.

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

Referring to fig. 2 again, the present utility model further provides a preferred embodiment, the clamp 2 in the anti-swing multiple steel sleeve hanger further includes at least two third hooks 24, the third hooks 24 are connected to the beam 1 and are located outside the two second hooks 23, respectively, and the first hooks 22, the second hooks 23 and the third hooks 24 are arranged along the same straight line perpendicular to the first plane. The third lifting hook 24 has the same structure as the first lifting hook 22, and can further improve the number of the disposable lifting steel sleeves 100 of the anti-swing multiple steel sleeve lifting tool. For example, two third lifting hooks 24 are provided in this embodiment, so that the swing-resistant multiple steel jacket lifting tool can lift four or five steel pipes at a time, and the pipe diameters of the multiple steel jackets can be different. Most importantly, the steel sleeve 100 clamped by the third lifting hook 24 can lean against the steel sleeve 100 clamped by the second lifting hook 23, and the corresponding steel sleeve of the third lifting hook 24 can be prevented from swinging. Similarly, when one clamp 2 is provided with six, nine or more hooks in actual practice, 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 be covered with a lining board, so as to play the same role as the liner 43, that is, prevent the hooks from extruding or scratching the end surface of the steel sleeve, reduce the generation of waste materials, and improve the product yield.

Referring to fig. 1 again, as a preferred embodiment, the number of the stabilizing frames 4 in the present embodiment is two, and the stabilizing frames are arranged along the extending direction of the cross beam 1, so as to improve the stabilizing effect, and at the same time, ensure that the swing-resistant multi-steel-sleeve lifting appliance has lighter weight. In practice, a greater number of stabilizing racks 4, for example three, five or eight, may be provided as desired.

As a preferred embodiment, the driving assembly 3 in this embodiment includes a hanger 31 and two tie rods 32. The hanger 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. Two tie rods 32 correspond to the two clamps 2 respectively, one end of each tie rod 32 is rotatably connected to the hanger 31, the other end of each tie rod 32 is rotatably connected to the corresponding clamp 2, and the rotation axes of the two ends of each tie rod 32 are perpendicular to the tie rod 32.

The above-mentioned mode is a mechanical driving, when the crane lifts the hanger 31, the two tie rods 32 are folded under the weight action of the cross beam 1, and the two ends of the steel sleeve 100 are clamped by the clamp 2 as the arm driving clamp. In order to improve the clamping force, the length of the pull rod 32 can be increased, and the structure does not need to be connected with an additional power source, so that the whole anti-swing multi-steel sleeve lifting tool is simpler and more easy to use. It is easy to understand that in practice, other devices may be used to drive the two clamps 2 to fold, for example, a hydraulic cylinder that can extend along a straight line is used as the driving component 3, two ends of the hydraulic cylinder are respectively connected to the two clamps 2, and the clamps 2 can be driven to fold or separate.

As shown in fig. 1 and 5, as a preferred embodiment, a beam 1 of the anti-swing multiple steel sleeve slings in this embodiment is provided with a kidney-shaped hole-shaped slide 11, and the clamp 2 further includes two sliding shafts 25, wherein both sliding shafts 25 pass through the slide 11, and one sliding shaft 25 also passes through one end of a pull rod 32 facing away from the hanger 31. Like the cross beam 1 and the jaw 21, the tie rod 32 is likewise composed of two flat and parallel long rods, in order to reduce the weight of the entire device. As can be seen, the tie rod 32 in this embodiment is located between the two sheets constituting the cross beam 1.

The slide shaft 25 also serves as a slider in addition to the articulation with the tie rod 32, for ensuring that the gripper 2 can slide linearly along the slideway 11. The sliding shaft 25 can also be sleeved with a roller sleeve, and parts such as an oil cup and the like can be installed to ensure lubrication. In this embodiment, one clamp 2 includes 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 a direction parallel to the axis of the steel sleeve and clamp the steel sleeve 100.

The utility model also provides a preferred embodiment, and the driving assembly 3 in the anti-swing multiple steel sleeve sling also comprises a sliding sleeve 33 and a sliding rod 34, which are combined with the figure 6. 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 cross beam 1. Two protrusions are symmetrically formed on the outer peripheral surface of the sliding sleeve 33 for hinging with one end of the two tie rods 32 facing away from the clamp 2, i.e. the tie rods 32 in this embodiment are connected to the hanger 31 through the sliding sleeve 33. One end of the slide bar 34 is vertically and fixedly connected with the middle part of the cross beam 1, and the other end of the slide bar 34 is slidably inserted into the slide sleeve 33. When the two tie rods 32 are retracted or expanded, the slide rod 34 can be retracted in the slide sleeve 33. At this time, the slide bar 34 and the slide sleeve 33 can enable the two clamps 2 to synchronously move, namely, the displacement is consistent, so that the gravity centers of the whole anti-swing multiple steel sleeve slings are always kept at one position, the skew is prevented, and the stability is improved.

As a preferred embodiment, the anti-swing multiple steel sleeve slings of the present embodiment further comprise a shutter 5, and two 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 cross beam 1. The shutter 5 is a common locking part in the field of lifting tools of the clamp 2, and in this embodiment, when the contact of the shutter 5 is clamped with the cross beam 1, the shutter 5 can be connected with the cross beam 1 and the sliding sleeve 33, so as to prevent the two from being separated, and ensure that the two clamps 2 are in an expanded state. When the lifting appliance is arranged below, the stabilizing frame 4 can touch a workpiece, so that the contact of the shutter 5 moves and is separated from the cross beam 1, and at the moment, along with the lifting of the lifting frame 31 and the sliding sleeve 33, the gravity of the cross beam 1 can enable the two pull rods 32 to be folded, and further the clamp 2 is folded and clamps the steel sleeve. The same applies when lowering the steel jacket, except that the state change of the whole anti-swing multiple steel jacket slings is opposite to the process described above.

In this specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, so that the same or similar parts between the embodiments are referred to each other.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
