Description

Technical Field

[0001] This utility model relates to hoisting technology for ultra-large steel components, and in particular to a turning buffer platform for ultra-large steel components. Background Technology

[0002] During the construction of steel structures, when hoisting ultra-large steel components, there is a momentary overturning phase during the adjustment of the component's lifting posture. At this instant, the component's posture is rapidly adjusted, causing significant swaying. The end face of the component may violently collide with the ground. During the component's posture adjustment, the wire rope is connected to the hoisting equipment, and the impact force at this moment is transmitted to the hoisting equipment, causing the boom of the hoisting equipment (tower crane, truck crane, etc.) to sway violently. This moment poses a significant safety hazard, and the end face of the large steel component may also suffer end damage due to the impact force.

[0003] Currently, the commonly used method for cushioning the impact of turning over on site is to place sleepers at the turning position of the steel structure. However, the safety and impact cushioning effect of sleepers are poor in actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a buffer platform for the overturning of ultra-large steel components, which solves the problem that the existing method of placing sleepers at the overturning position of the steel column is not very safe and has a poor effect on the release of impact force during the overturning stage of ultra-large steel components during hoisting.

[0005] To address the aforementioned problems, this utility model provides an ultra-large steel component turning buffer platform, comprising a base frame, a rotating shaft rotatably connected to one side of the base frame, rotating handles fixed at both ends of the rotating shaft, a platform frame installed between the two rotating handles, a guide rod fixed in the middle of the platform frame, a buffer platform provided on the guide rod, a support rod hinged to the side of the platform frame away from the rotating handle via a connecting shaft, multiple evenly spaced positioning slots opened on the base frame, the support rods being inserted into the corresponding positioning slots, and a rubber buffer pad provided on the buffer platform.

[0006] The ultra-large steel component turning and buffer platform provided by this utility model also has the following technical features:

[0007] Furthermore, the buffer platform is slidably connected to the guide rod.

[0008] Furthermore, the bottom of the buffer platform is threaded with a positioning bolt, and the bottom of the guide rod is provided with multiple positioning holes, into which the positioning bolt can be inserted.

[0009] Furthermore, rotating columns are fixed on both sides of the guide rod. The rotating columns pass through the platform frame and are rotatably connected to the corresponding rotating handle. A polygonal groove is opened on one side of the rotating handle. A polygonal tube is fitted on the rotating column. The polygonal tube is slidably connected to the platform frame. The free end of the polygonal tube can be inserted into the corresponding polygonal groove.

[0010] Furthermore, the polygonal tube is connected to the guide rod via a spring on the side closest to the guide rod, and the spring is fitted onto the rotating column.

[0011] This invention has the following advantages: By adjusting the angle of the platform frame, the angle between the buffer platform and the bottom frame can be 15 to 20 degrees. The device can be designed according to the cross-sectional size and weight of large components. With the buffer platform and rubber buffer pad, the component will come into contact with the rubber buffer pad at the moment of overturning. The rubber buffer pad absorbs the huge impact force transmitted at the moment of overturning, avoiding the huge impact force from affecting the hoisting equipment and the end face of the steel component. Compared with the method of placing sleepers at the overturning position of the steel component, this device has better safety and impact force buffering and release effect.

A support rod 7 is hinged to the side of the platform frame 4 away from the rotating handle 3 via a connecting shaft. A plurality of equidistant positioning grooves 8 are opened on the base frame 1. The support rod 7 can be inserted into the corresponding positioning groove 8. The bottom of the support rod 7 is inserted into the groove. The angle of the platform frame 4 can be adjusted in the positioning groove 8 at the same position. The buffer platform 6 is equipped with a rubber buffer pad 9. By adjusting the angle of the platform frame 4, the angle between the buffer platform 6 and the bottom frame 1 is 15 to 20 degrees. This device can be designed according to the cross-sectional size and weight of large components. With the setting of the buffer platform 6 and the rubber buffer pad 9, the component will come into contact with the rubber buffer pad 9 at the moment of overturning.

The free end of the polygonal tube 12 can be inserted into the corresponding polygonal groove. By inserting the polygonal tube 12 into the corresponding polygonal groove, the angle between the platform frame 4 and the rotating handle support can be adjusted, thereby facilitating further adjustment of the angle of the platform frame 4.

[0021] In one embodiment of this application, preferably, the polygonal tube 12 is connected to the guide rod 5 via a spring on the side near the guide rod 5, and the spring is fitted on the rotating column 11, so that the polygonal tube 12 can be inserted into the corresponding polygonal groove under the action of the spring.
