Description

Technical Field

[0001] This utility model belongs to the field of steel structure installation technology, specifically relating to a lifting device for steel structure beams. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates. Their advantages include light weight, high strength, and easily guaranteed quality. In the construction and manufacturing fields, their function is to bear weight and transfer loads. Their structural forms include beams and trusses, with common beam types including H-beams, I-beams, and C-beams, among which H-beams are one of the most frequently used component types.

[0003] In existing related technologies, the length of the crossbeams in different parts of the steel structure is different during installation, resulting in poor clamping and fixing effect of the steel structure crossbeams. This leads to the steel structure crossbeams being prone to loosening and falling during hoisting. It cannot be well applied to clamping and hoisting steel structure crossbeams of different lengths. Therefore, there is an urgent need to design a lifting device for steel structure crossbeams to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model discloses a lifting device for steel structure beams.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A lifting device for a steel structure beam includes a base, a bearing mechanism above the base, and a movable clamping mechanism on the bearing mechanism.

[0007] The movable clamping mechanism includes rotating shafts on both sides of the bearing mechanism. End plates are rotatably mounted on the outer surface of the rotating shafts. A rotary motor is mounted on one end of the rotating shaft. A hollow sleeve is fixedly mounted longitudinally parallel to the lower end of the bearing mechanism. A longitudinal limiting plate is movably mounted inside the hollow sleeve. A protective clamp is mounted on the longitudinal limiting plate. A positioning component is provided on the hollow sleeve. A drive motor is fixedly mounted on the bearing mechanism. A lead screw is mounted on the power end of the drive motor. A moving frame is mounted on the outer surface of the lead screw. An electric telescopic rod is mounted on the moving frame. A backing plate is fixedly mounted on the telescopic end of the electric telescopic rod.

[0008] Preferably, the bearing mechanism includes a bearing plate fixedly mounted above the base, a crossbeam above the bearing plate, a hoisting assembly fixedly mounted on the base, a limit bar fixedly mounted laterally on the hoisting assembly, a vertical plate fixedly mounted on the limit bar, and a first guide rod horizontally parallel to the lower end of the base and fixedly mounted on the hoisting assembly.

[0009] Preferably, a soft protective anti-slip pad is fixedly installed at the lower end of the backing plate, and the protective clamp is made of soft material.

[0010] Preferably, the positioning component includes a positioning hole provided on the hollow sleeve, and a positioning rod is installed in the positioning hole.

[0011] Preferably, a damping spring is installed between the base and the support plate.

[0012] Preferably, the lifting assembly includes a lifting frame fixedly mounted on the base, and a lifting ring is fixedly installed on the lifting frame.

[0013] The beneficial effects are:

[0014] This utility model discloses a lifting device for a steel structure beam. Through a movable clamping mechanism, a rotary motor is activated to rotate the shaft, causing the end plates to rotate at a certain angle, thus limiting the two ends of the beam. The longitudinal limiting plate and protective clamp are placed inside the hollow sleeve and positioned by a positioning assembly. A drive motor is then activated to rotate the lead screw, causing the moving frame to move laterally on both sides of the beam. Once the moving frame reaches a certain position, it stops. An electric telescopic rod installed above the moving frame then pushes the bracing plate to move, securing the beam and ensuring its stability. This improves lifting efficiency, provides stable positioning of the beam, effectively reduces the probability of the beam falling, and offers superior safety and practicality.

[0024] Reference Figure 1-5 One embodiment of this utility model is a lifting device for a steel structure beam, including a base 1, a bearing mechanism 2 above the base 1, and a movable pressing mechanism 3 on the bearing mechanism 2.

[0025] In this embodiment: the supporting mechanism 2 includes a supporting plate 201 fixedly mounted above the base 1, a crossbeam 203 above the supporting plate 201, a hoisting assembly fixedly mounted on the base 1, a limiting square rod 208 horizontally fixedly mounted on the hoisting assembly, a vertical plate 206 fixedly mounted on the limiting square rod 208, and a first guide rod 207 horizontally parallel to the lower end of the base 1 and fixedly mounted on the hoisting assembly. The first guide rod 207 has a cylindrical cross-section. A damping spring 202 is installed between the base 1 and the supporting plate 201. The hoisting assembly includes a hoisting frame 204 fixedly mounted on the base 1, and a hoisting ring 205 fixedly mounted on the hoisting frame 204.

[0026] In this embodiment: the movable pressing mechanism 3 includes rotating shafts 301 disposed on both sides of the bearing mechanism 2. End plates 302 are rotatably mounted on the outer surface of the rotating shafts 301. A rotary motor 303 is mounted on one end of the rotating shafts 301. The rotary motor 303 is a 90-degree forward and reverse rotation motor, which is existing technology and will not be described further here. A hollow sleeve 305 is longitudinally and parallelly fixedly mounted at the lower end of the bearing mechanism 2. A longitudinal limiting plate 304 is relatively movably mounted inside the hollow sleeve 305. A partition is fixedly disposed inside the hollow sleeve 305 to limit the longitudinal limiting plate 304. A protective clamping plate 3041 is installed on the longitudinal limiting plate 304. A positioning component is provided on the hollow sleeve 305. A drive motor 310 is fixedly installed on the bearing mechanism 2. A lead screw 309 is installed on the power end of the drive motor 310. A movable frame 306 is installed on the outer surface of the lead screw 309. An electric telescopic rod 307 is installed on the movable frame 306. A bracing plate 308 is fixedly installed on the telescopic end of the electric telescopic rod 307. A soft protective anti-slip pad is fixedly provided at the lower end of the bracing plate 308. The protective clamping plate 3041 is made of soft material. The positioning component includes a positioning hole 3052 provided on the hollow sleeve 305. A positioning rod 3051 is installed in the positioning hole 3052. The movable frame 306 is slidably connected to the first guide rod 207.

The movable frame 306 and the lead screw 309 are connected by threads.

[0027] Working principle: In use, firstly, the end plate 302 is rotated and moved by the angle motor 303 to be on the same horizontal plane as the support plate 201. The crossbeam 203 to be hoisted is placed above the support plate 201, and shock absorption is achieved by the damping spring 202. After the crossbeam 203 is placed, the angle motor 303 is started to rotate the end plate 302 90 degrees, making the end plate 302 perpendicular to the support plate 201, thus limiting the two ends of the crossbeam 203 to be hoisted. The hoisting can be adjusted according to the length of the crossbeam to be hoisted. When the beam 203 is long, start the drive motor 310 to rotate the lead screw 309, drive the moving frame 306 to move laterally, and drive the electric telescopic rod 307 and the backing plate 308 to move laterally. When it moves to a certain position, stop, and start the electric telescopic rod 307 to push the backing plate 308 down so that the backing plate 308 contacts the beam 203 to fix the beam 203. Finally, hang the external hook in the lifting ring 205 set at the top of the lifting frame 204 to start lifting.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
