Description

Technical Field

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

[0002] In steel structure engineering, the role of steel structure hoisting device is very important. It can lift steel structure components composed of large steel beams, steel columns, steel plates, etc. to the designated location for installation and fixing.

[0003] The utility model with the authorization announcement number CN 219116978 U discloses a steel structure hoisting device for construction, including: a hoist, a top hanging plate, an upper fixing mechanism, a side fixing beam, a lower fixing mechanism and a combined mechanism; both sides of the hoist are equipped with lifting ropes; both sides of the top hanging plate are connected with collars, and the lifting ropes are connected to the collars; the upper fixing mechanism is fixedly installed on the lower wall of the top hanging plate; a pair of side fixing beams are fixedly installed on both sides of the upper fixing mechanism; the lower fixing mechanism is fixedly installed between a pair of side fixing beams; and the combined mechanism is arranged on one side wall of the side fixing beam. The two pairs of steel structures are completely fixed by the upper fixing mechanism and the lower fixing mechanism, the side fixing beam can connect the upper fixing mechanism and the lower fixing mechanism, the upper fixing mechanism can limit the top and bottom of the steel structure, and the lower fixing mechanism can limit the left and right sides of the steel structure, so that several steel structures can be hoisted at the same time.

[0004] Although the utility model can fix the steel structure through the upper fixing mechanism and the lower fixing mechanism, and can connect the upper fixing mechanism and the lower fixing mechanism through the side fixing beam to hoist several steel structures at the same time, there are the following two problems:

[0005] 1. When fixing the steel structure through the upper fixing mechanism and the lower fixing mechanism, the steel structure needs to be placed on the lower fixing plate first. Since the steel structure is large and heavy, it is laborious to place it on the lower fixing plate manually, and more manpower is required to lift the steel structure together. It is a bit redundant to use other lifting equipment.

[0006] Second, building steel structures is an aerial work, and the working space is limited by the influence of the altitude. Therefore, it is not practical to hoist several steel structures at the same time in the utility model. Instead, it will increase the difficulty of the work and increase the danger of workers working at altitude.

[0007] Therefore, those skilled in the art provide a hoisting device for steel structure construction to solve the problems raised in the above background technology. Utility Model Content

[0008] The purpose of the utility model is to provide a hoisting device for steel structure construction to solve the problems raised in the above background technology.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A lifting device for steel structure construction includes a lifting tool, a clamping device 1 and a clamping device 2. The clamping device 1 is fixedly connected to the lifting tool through a sling 1, and the clamping device 2 is fixedly connected to the lifting tool through a sling 2. The clamping device 1 and the clamping device 2 have the same structure, and mainly include a top plate, a lifting ring, a left clamping plate, a right clamping plate and a double-threaded screw.

[0011] As a further solution of the utility model: the lifting ring is fixedly installed at the center of the upper end of the top plate, the upper end of the top plate near the left end is provided with a first slide groove, and the upper end of the top plate near the right end is provided with a second slide groove.

[0012] As a further solution of the utility model: two sliding rods are fixedly connected to the left inner walls of the slide groove one and the slide groove two, and the right ends of the sliding rods are fixedly connected to the right inner walls of the slide groove one and the slide groove two.

[0013] As a further solution of the utility model: two through holes are provided on one side of the left splint and the right splint near the upper end, the two through holes on the left splint are sleeved on the two slide rods in the first slide groove, and the two through holes on the right splint are sleeved on the two slide rods in the second slide groove.

[0014] As a further solution of the utility model: the left clamping plate can slide in the first slide groove through the two slide rods in the first slide groove, and the right clamping plate can slide in the second slide groove through the two slide rods in the second slide groove.

[0015] As a further solution of the utility model: a lower clamping block is fixedly connected to a position near the lower end of one end of the left clamping plate close to the right clamping plate, and a same lower clamping block is fixedly connected to a position near the lower end of one end of the right clamping plate close to the left clamping plate, and a wedge block is fixedly connected to each of the lower clamping blocks.

[0016] As a further solution of the utility model: an upper clamping block is fixedly connected to one side of the left clamping plate close to the right clamping plate, and the same upper clamping block is also fixedly connected to one side of the right clamping plate close to the left clamping plate.

[0017] As a further solution of the utility model: a side of the left clamping plate close to the right clamping plate is fixedly connected with a threaded block, and a side of the right clamping plate close to the left clamping plate is also fixedly connected with a threaded block.

[0018] As a further solution of the utility model: one end of the double-threaded screw is fixedly connected to a turning handle, and the double-threaded screw is threadedly connected to the threaded block on the left clamping plate and the threaded block on the right clamping plate.

[0019] As a further solution of the utility model: the threaded block on the left clamping plate and the threaded block on the right clamping plate, one has a positive thread and the other has a negative thread, and the positive and negative threads on the threaded screw rod match them.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The new type of implementation drives the double-threaded screw to rotate by rotating the handle, so that the left clamping plate and the right clamping plate can move toward each other through the cooperation of the positive and negative threads on the double-threaded screw and the threaded block, so that the clamping width of the left clamping plate and the right clamping plate can be adjusted to clamp steel structures of different sizes.

[0022] 2. When the handle is rotated, the utility model drives the left clamping plate and the right clamping plate to move toward each other, thereby clamping the I-beam. When the left clamping plate and the right clamping plate move toward each other, the wedge block also moves together. When the left clamping plate and the right clamping plate are constantly approaching, the I-beam can be firmly clamped by the wedge block and the upper clamping block, thereby completing the lifting. The operation is simple and quick. When the I-beam is lifted to the working area at a high altitude, it is relatively simple for the staff working at high altitude to unfasten the buckle. Simplifying the actions of the operators can reduce the danger of people working at high altitude. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting ring 6 is fixedly installed at the center of the upper end of the top plate 7. A slide groove 12 is opened at the upper end of the top plate 7 near the left end. A second slide groove 13 is provided near the right end of the end, and two slide rods 14 are fixedly connected to the left inner walls of the slide grooves 12 and 13. The right ends of the slide rods 14 are fixedly connected to the right inner walls of the slide grooves 12 and 13. Two through holes 15 are provided near the upper ends of one side of the left clamping plate 8 and the right clamping plate 9. The two through holes 15 on the left clamping plate 8 are sleeved on the two slide rods 14 in the slide groove 12, and the two through holes 15 on the right clamping plate 9 are sleeved on the two slide rods 14 in the slide groove 2.

The left splint 8 is fixedly connected to an upper clamping block 17 on one side of the right splint 9, and the right splint 9 is also fixedly connected to the left splint 8 on one side. It is fixedly connected with the same upper clamping block 17, and a threaded block 16 is fixedly connected to the side of the left clamping plate 8 close to the right clamping plate 9, and a threaded block 16 is also fixedly connected to the side of the right clamping plate 9 close to the left clamping plate 8.

[0032] The working principle of the utility model is as follows: when the utility model is used, the double-threaded screw rod 10 is first rotated by the turning handle 11, and the left and right splints 8 and 9 are moved in the opposite direction through the slide rod 14 through the cooperation of the positive and negative threads on the double-threaded screw rod 10 and the threaded block 16, so as to increase the distance between the left and right splints 8 and 9, and then the upper clamping block 17 is placed on the upper end surface of the I-beam 20, and then the double-threaded screw rod 10 is rotated by the turning handle 11, so that the left and right splints 8 and 9 move toward each other, so that the left and right splints 8 and 9 move in the opposite direction. The clamping plates 9 move closer to each other. When the left clamping plate 8 and the right clamping plate 9 move closer to each other, the wedge block 19 on the lower clamping block 18 will also move simultaneously, and the upper end surface of the I-beam 20 will be shoveled onto the wedge block 19. The I-beam 20 can be firmly clamped by the wedge block 19 and the upper clamping block 17. Through the above, the clamping device 1 4 and the clamping device 2 5 are respectively clamped at the positions near the two ends of the I-beam 20, and then the I-beam 20 is lifted by the external equipment through the sling 1, the sling 1 2 and the sling 2 3.
