Description

Technical Field

[0001] The present application relates to the technical field of hoisting devices, and in particular to a hoisting device for a portal steel frame structure. Background Art

[0002] As a representative of green buildings, steel structure has good comprehensive material performance, high material utilization rate and superior safety performance. As a component of the main sub-project of the building, the main steel columns, steel beams and other components of the steel structure can be prefabricated in advance and then transported to the construction site. They can be assembled and fixed on site through welding connections and fastener connections between components. The portal steel frame is a traditional structural system. The upper main structure of this type of structure includes steel frame inclined beams, rigid frame columns, supports, purlins, tie rods, gable frames, etc. The portal rigid frame light house steel structure has the characteristics of simple force, clear force transmission path, quick component production, easy factory processing, and short construction period. Therefore, it is widely used in industrial and civil buildings such as industry, commerce, and cultural and entertainment public facilities.

[0003] A search revealed that Chinese patent publication number CN214399535U discloses a portal steel frame structure hoisting device comprising a hollow crossbeam and an adjustment assembly. Sliding lining beams are inserted at both ends of the hollow crossbeam, and mounting seats are fixedly mounted on the opposite ends of the two lining beams. An anti-sway assembly is mounted at the bottom of each mounting seat. The adjustment assembly is mounted on one side of the hollow crossbeam, and the spacing between the two lining beams within the hollow crossbeam is adjusted by the adjustment assembly. Both sides of the inner cavity wall of the hollow crossbeam are provided with integrally formed ribs, and grooves are provided on both side walls of the two lining beams. The ribs are inserted into the grooves of the lining beams and are slidably connected thereto. The portal steel frame structure hoisting device provided by this utility model has the advantage of being easily adjustable.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: the above-mentioned scheme can adjust the distance between the two mounting seats according to the different widths of the gantry steel frames, and turn on the drive motor to drive the screw to rotate. Since the screw is provided with two opposite threaded sections, the threaded connecting sleeve drives the two lining beams to slide back or toward each other, so that the width of the horizontal hanger formed by the hollow crossbeam and the lining beam becomes wider, which is convenient for fixing and lifting gantry steel frames of different widths. However, this device can only adjust the distance according to steel frames of different widths. When facing steel frames of different specifications, it can only squeeze and clamp the steel frames at both ends. During the lifting process, the steel frame will slide out of the U-shaped plate due to uneven force, resulting in the risk of the steel frame falling. Therefore, a new way is needed to solve this problem. Utility Model Content

[0021] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0022] The embodiment of the present application discloses a portal steel frame structure hoisting device. Figure 1 As shown, it includes a beam 1 and two connecting frames 7. A first motor 2 is fixedly installed on the upper surface of the beam 1. The output end of the first motor 2 is fixedly connected to a first bidirectional screw 3. The outer surface of the first bidirectional screw 3 is threadedly connected to two support frames 4. The outer surface of each support frame 4 is slidingly connected to the beam 1, and the outer surface of the first bidirectional screw 3 is rotationally connected to the beam 1. Specifically, by starting the first motor 2, the first motor 2 will drive the first bidirectional screw 3 to rotate on the beam 1. The upper surface of the beam 1 is fixedly connected to two connecting plates. The first motor 2 is arranged on one of the connecting plates, and the first bidirectional screw 3 can rotate in the two connecting plates. At this time, the rotation of the first bidirectional screw 3 will drive the two support frames 4 to slide horizontally oppositely or reversely along the beam 1 at the same time, so that it can be adjusted according to the clamping parts of the steel frames of different lengths.

[0023] See also Figure 1 、 Figure 2 The ends of the two support frames 4 that are away from each other are fixedly connected with connecting blocks 5, and a telescopic rod 6 is fixedly installed on the bottom surface of each connecting block 5. The output end of each telescopic rod 6 is fixedly connected to the corresponding connecting frame 7. Through the connection between the connecting block 5 and the corresponding telescopic rod 6, the horizontal sliding of the support frame 4 will drive the telescopic rod 6 to move horizontally. By starting the telescopic rod 6, it will adjust the height of the clamping mechanism according to the steel frame of different heights through its own extension or contraction.

[0024] See also Figure 1 、 Figure 2 A second motor 8 is fixedly mounted on the outer surface of each connecting frame 7, and a second bidirectional screw 9 is fixedly connected to the output end of each second motor 8. The outer surface of each second bidirectional screw 9 is fixedly connected to the corresponding connecting frame 7, and the outer surface of each second bidirectional screw 9 is threadedly connected to two fixing frames 10. By starting the second motor 8, the second motor 8 will drive the corresponding second bidirectional screw 9 to rotate, and the rotation of the second bidirectional screw 9 will drive the corresponding two fixing frames 10 to slide in opposite or reverse directions along the corresponding connecting frame 7 at the same time, and thereby can be adjusted according to steel frames of different widths.

[0025] See also Figure 3The inner wall of each fixing frame 10 is slidably connected to two plug rods 14, and the outer surface of each plug rod 14 is sleeved with a spring 15, and one end of each spring 15 close to the corresponding first slot 13 is fixedly connected to the corresponding plug rod 14, and the other end is fixedly connected to the corresponding fixing frame 10. The outer surface of each plug block 12 is provided with a first slot 13, and the outer surface of each plug rod 14 is plugged into the corresponding first slot 13. By pulling the plug rod 14 to make it slide vertically along the corresponding fixing frame 10, the spring 15 will be compressed until the plug rod 14 leaves the corresponding second slot 16. At this time, the plug block 12 is inserted into the corresponding second slot 16 until the plug rod 14 and the corresponding first slot 13 are on the same central axis, and then the plug rod 14 is released. The spring 15 will push the corresponding plug rod 14 into the corresponding first slot 13 under the action of its rebound force, so that the clamping member 11 can be quickly disassembled and assembled.

[0026] See also Figure 3 、 Figure 4 Two second slots 16 are provided on the outer surface of each fixing frame 10, and an insert block 12 is inserted into the inner wall of each second slot 16. The outer surface of each insert block 12 is fixedly connected to a clamping member 11, and a T-shaped slide groove 17 is provided inside each clamping member 11. By inserting the insert block 12 of the clamping member 11 along the corresponding second slot 16 and quickly disassembling and fixing the insert block 12, the clamping member 11 can be quickly installed and fixed. By replacing the clamping member 11, it is also easy to adapt to steel frames of more specifications.

[0027] See also Figure 4 The upper surface of each clamping plate 20 is rotatably connected to the inner wall of each T-shaped slide 17, and the upper surface of each clamping plate 20 is rotatably connected to the first screw 18. The top of each first screw 18 is fixedly connected to a connecting head 19, and the outer surface of each first screw 18 is threadedly connected to the corresponding clamping piece 11. The clamping plate 20 can slide vertically along the corresponding T-shaped slide 17. The setting of the T-shaped slide 17 can constrain the clamping plate 20 by rotating the connecting head 19, or using a tool to connect the connecting head 19 for easy rotation. Then the first screw 18 will rotate, and through the connection between it and the corresponding clamping piece 11, the rotation of the first screw 18 will push the corresponding clamping plate 20 to slide vertically along the T-shaped slide 17. In this way, the clamping plate 20 can be used to quickly and tightly clamp steel frames of different thicknesses. By clamping both sides of the steel frame, the risk of the steel frame falling off due to uneven force can be prevented.

[0028] The implementation principle of the portal steel frame structure lifting device of the embodiment of the present application is as follows: first, according to the height and length of the steel frame, the adjustment is performed. At this time, by starting the first motor 2 and the telescopic rod 6, the start of the first motor 2 will drive the first bidirectional screw 3 to rotate, and the spacing between the two telescopic rods 6 can be adjusted by the first bidirectional screw 3. The extension or contraction of the telescopic rod 6 can push the corresponding connecting frame 7 to move vertically. At this time, the plug block 12 with the clamping part 11 should be inserted into the corresponding second slot 16 first. Before that, the plug rod 14 should be pulled to slide vertically along the corresponding fixing frame 10. At this time, the spring 15 will be compressed until the plug rod 14 leaves the corresponding second slot 16, until the plug rod 14 is aligned with the corresponding first The slots 13 are on the same central axis, and then the insertion rod 14 is loosened. The spring 15 will push the corresponding insertion rod 14 into the corresponding first slot 13 under the action of its rebound force, so that the clamping part 11 can be quickly disassembled and assembled, and then different clamping parts 11 are selected according to steel frames of different specifications. At this time, the second motor 8 is started according to steel frames of different specifications. The second motor 8 will drive the corresponding second bidirectional screw 9 to rotate. The rotation of the second bidirectional screw 9 will drive the corresponding two fixing frames 10 to slide in opposite or reverse directions along the corresponding connecting frame 7 at the same time, and thereby clamp the lateral sides of the steel frame. Finally, by using a tool to rotate the connecting head 19, it will push the corresponding clamping plate 20 to quickly clamp and fix the steel frame.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
