Description

Technical Field

[0001] The utility model relates to the technical field of steel structure hoisting, in particular to a hoisting device for steel structure construction. Background Art

[0002] Steel structure is a structure made of steel materials, which is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. H-shaped steel and I-shaped steel are one of the steel structures. When they are installed, a lifting device is needed to assist in connecting them. A Chinese utility model patent with announcement number CN216471787U discloses a steel structure lifting device for construction, which can not only hold and fix H-shaped steel, but also adapt to H-shaped steel of different lengths. When fixing the H-shaped steel, one end of the H-shaped steel needs to be inserted into the belly groove of the hanger frame, so that the H-shaped steel can be fixed. When the H-shaped steel is connected to other steel structures, the outer end of the steel structure will be blocked by other steel structures, which makes the lifting furniture unable to be removed, and the H-shaped steel part will be directly placed on the ground or stacked, so that the bottom end of the H-shaped steel is not in a suspended state. When the H-shaped steel is inserted into the belly groove of the hanger frame, the H-shaped steel also needs to be lifted, which makes the operation more troublesome. To this end, we designed a lifting device for steel structure construction. Utility Model Content

[0003] In order to solve the technical problem that the hoisting device is difficult to remove after the H-shaped steel is hoisted, the utility model provides a hoisting device for steel structure construction.

[0004] The utility model is implemented by the following technical scheme: a hoisting device for steel structure construction, comprising a plurality of symmetrically arranged buckle frames, a notch is arranged on the inner side of the buckle frame to form a card interface, a support seat is installed at the bottom end of the card interface, four evenly distributed threaded holes are opened on the top of the buckle frame, four locking screws are threadedly connected to the buckle frame through the threaded holes, and the lower end of the locking screw is inside the card interface and is provided with a clamping plate;

[0005] A lifting ring is welded at the middle of the upper part of the buckle frame, and a connecting branch rope is connected to the lifting ring, and one end of the four connecting branch ropes away from the lifting ring is connected to the steel rope.

[0006] As a further improvement of the above scheme, the outer half of the upper surface of the support seat is horizontally designed to form a contact plane, the flange of the H-shaped steel is flat, and the contact plane is directly used to contact the H-shaped steel, and the inner half of the upper surface of the support seat is cut away to form a contact arc surface. The I-beam is a rolled section. Due to poor production technology, the inner edge of the flange has a slope of 1:10. The set contact arc surface has the same slope as its flange, so that the contact arc surface can fit on the lower surface of the I-beam, so that it can be clamped and fixed, and the connection between the contact arc surface and the contact plane is chamfered to form an arc surface.

[0007] As a further improvement of the above-mentioned scheme, the two locking screws and the clamping plate on the outward side of each support seat are located directly above the contact plane, and the two locking screws and the clamping plate on the inward side of each support seat are located directly above the contact arc surface. The clamping plate can press the upper surface of the H-shaped steel or I-shaped steel below as needed, so that the flange of the I-shaped steel can better contact the contact arc surface, thereby preventing it from falling off.

[0008] As a further improvement of the above scheme, a through-interface is opened above the outer ring surface of the locking screw, and a rotating rod is movably inserted into the through-interface. The rotating rod can be inserted into the through-interface to rotate the locking screw, and it can be removed after use.

[0009] As a further improvement of the above scheme, a circular groove is formed in the middle of the clamping plate, the bottom end of the locking screw is placed in the circular groove, and the two are fixed by screws, which is convenient for installation and removal of the clamping plate;

[0010] The bottom surface of the pressing plate, the contact plane surface and the contact arc surface are all designed to be rough, which increases the resistance during contact and makes it difficult to slide and fall off.

[0011] As a further improvement of the above scheme, four circular holes are opened at the bottom of the buckle frame, and the four circular holes are respectively located directly below the four threaded holes. After the clamping plate is placed at the lower end of the locking screw, the countersunk screw can be screwed into the clamping plate and the locking screw through the circular holes, and the screwdriver can also be inserted into the card interface through the circular holes;

[0012] A countersunk screw hole is provided at the bottom end of the snap-on frame, and the snap-on frame is connected to the support seat via a countersunk screw, which facilitates installation and removal of the support seat, thereby facilitating subsequent replacement.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides four buckle frames, which can be respectively clamped at both ends of the H-shaped steel, and cooperate with the provided locking screws and the clamping plate to enable them to be tightly pressed on the support seat, thereby facilitating the fixed hoisting of the H-shaped steel, and after hoisting, the buckle frames can be directly removed through the side thereof;

[0015] 2. A support seat is provided at the bottom of the aperture frame, and a contact plane and a contact arc surface are provided on the support seat. The contact arc surface has the same slope as its flange, so that the contact arc surface can fit on the lower surface of the I-beam. This enables the device to hoist H-beams and I-beams, and has diversity. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0025] Please combine Figure 1-Figure 5A lifting device for steel structure construction in this embodiment includes a plurality of symmetrically arranged buckle frames 1, a notch is arranged on the inner side of the buckle frame 1 to form a card interface, a support seat 2 is installed at the bottom end of the card interface, four evenly distributed threaded holes are opened on the top of the buckle frame 1, four locking screws 3 are threadedly connected to the buckle frame 1 through the threaded holes, the lower end of the locking screw 3 is located inside the card interface and is provided with a clamping plate 31, a lifting ring 5 is welded at the middle of the top of the buckle frame 1, a connecting rope 7 is connected to the lifting ring 5, and the ends of the four connecting ropes 7 away from the lifting ring 5 are connected to the steel rope 6.

[0026] The outer half of the upper surface of the support seat 2 is horizontally designed to form a contact plane 22. The flange of the H-shaped steel is flat, and the contact plane 22 is directly used to contact the H-shaped steel. The inner half of the upper surface of the support seat 2 is cut away to form a contact arc surface 21. The I-shaped steel is a rolled section. Due to poor production technology, the inner edge of the flange has a slope of 1:10. The contact arc surface 21 is set with the same slope as its flange, so that the contact arc surface 21 can fit on the lower surface of the I-shaped steel, so that it can be clamped and fixed. The connection between the contact arc surface 21 and the contact plane 22 is chamfered to form an arc surface 23.

[0027] The two locking screws 3 and the clamping plate 31 on the outward side of each support seat 2 are directly above the contact plane 22, and the two locking screws 3 and the clamping plate 31 on the inward side of each support seat 2 are directly above the contact arc surface 21. The clamping plate 31 can press the upper surface of the H-shaped steel or I-shaped steel below as needed, so that the flange of the I-shaped steel can better contact with the contact arc surface 21, thereby preventing it from falling off.

[0028] A through-interface is provided above the outer ring surface of the locking screw 3, and a rotating rod 4 is movably inserted into the through-interface. The rotating rod 4 can be inserted into the through-interface to rotate the locking screw 3, and it can be removed after use.

[0029] A circular groove is formed in the upper middle of the pressure plate 31, and the bottom end of the locking screw 3 is placed in the circular groove, and the two are fixed by screws, which is convenient for the installation and disassembly of the pressure plate 31. The bottom surface of the pressure plate 31 and the surfaces of the contact plane 22 and the contact arc surface 21 are all rough in design, which increases the resistance during contact and makes it difficult to slide and fall off.

[0030] Four circular holes are provided at the bottom end of the snap-on frame 1, and the four circular holes are respectively located directly below the four threaded holes. After the clamping plate 31 is placed at the lower end of the locking screw 3, the countersunk screw can be screwed into the clamping plate 31 and the locking screw 3 through the circular hole, and the screwdriver can also be extended into the card interface through the circular hole. Countersunk screw holes are provided at the bottom end of the snap-on frame 1, and the snap-on frame 1 and the support seat 2 are connected by countersunk screws, which is convenient for the installation and disassembly of the support seat 2, thereby facilitating subsequent replacement.

[0031] The implementation principle of a hoisting device for steel structure construction in the embodiment of the present application is as follows: in actual use, the end of the steel rope 6 away from the connecting branch rope 7 is connected to the crane, and the buckle frames 1 on the left and right sides are respectively located at the front and rear ends of the left and right sides of the H-shaped steel according to the length of the H-shaped steel, and the card interface of the buckle frame 1 is carded at the upper edge of the H-shaped steel, and the rotating rod 4 is inserted into the through-interfaces of multiple locking screws 3 one by one and the locking screw 3 is rotated, so that the locking screw 3 drives the clamping plate 31 to move downward and is tightly pressed on the upper surface of the H-shaped steel, so that it can be fixed (such as Figure 4 As shown), since a contact arc surface 21 matching the flange of the I-shaped steel is also provided on the support seat 2, the contact arc surface 21 can contact the flange of the I-shaped steel, thereby also being able to press and fix the I-shaped steel, thereby facilitating its hoisting;

[0032] By setting four buckle frames 1, the four buckle frames 1 can be respectively clamped at the two ends of the H-shaped steel, and cooperate with the provided locking screws 3 and the clamping plate 31, so that they can be tightly pressed on the support seat 2, thereby facilitating the fixed lifting of the H-shaped steel, and after lifting, the buckle frames 1 can be directly removed through the side thereof;

[0033] A support seat 2 is provided at the bottom end of the inner part of the aperture frame, and a contact plane 22 and a contact arc surface 21 are provided on the support seat 2. The contact arc surface 21 has the same slope as its flange, so that the contact arc surface 21 can fit on the lower surface of the I-beam. This enables the device to lift H-beams and I-beams, and has diversity.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
