Technical Field

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

[0002] All existing large steel structure buildings need to use temporary supports to assist assembly. After completing the installation and interface welding work, the structure must be unloaded before the temporary supports can be removed to allow the structure to complete the overall force.

[0003] When the load is not stable, the load is not uniform.

[0004] In the prior art, a Chinese patent with a publication number of CN210232002U is proposed to solve the above-mentioned technical problems.

The utility model cuts the through groove of the top unloading plate, and then a sheet-removing wrench is provided to remove the unloading plate of the top layer. At this time, the unloading cylinder as a whole moves down by the thickness of an unloading plate under the reaction force of the shock-absorbing spring inside it, and continues to cut the unloading plate until the unloading cylinder moves down, and the arc support plate is separated from the steel structure supported above it, and the unloading is completed. The unloading is stable and easy to operate.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments: Example

[0029] like Figure 1-5As shown, the utility model provides a novel steel structure unloading device, including a support frame 1, an unloading device 2 and a detachable plate frame 3, the detachable plate frame 3 is detachably arranged on the top of the unloading device 2, and the unloading device 2 includes a pressure-bearing column 4, a pressure-bearing sand barrel 5 and a closed collar 7 arranged on the top of the support frame 1 from top to bottom. The pressure-bearing column 4 and the pressure-bearing sand barrel 5 are both made of high-strength and corrosion-resistant metal materials, and have sufficient strength to support the huge weight of the steel structure.

[0030] The outer wall of the bottom end of the pressure-bearing column 4 is plugged into the inner wall of the pressure-bearing sand tube 5, and a sand tube lower sand hole 11 is provided on the outer wall of the pressure-bearing sand tube 5 near the bottom end. The closed collar 7 is movably sleeved on the outer wall of the bottom end of the pressure-bearing sand tube 5, and a collar lower sand hole 12 corresponding to the sand tube lower sand hole 11 is provided on the outer wall of the closed collar 7.

[0031] The outer wall of the closed collar 7 near the top is fixedly connected with a rotating outer ring frame 16, and the bottom surface of the rotating outer ring frame 16 is fixedly connected with a sand ring bag 6, and the closed end of the sand ring bag 6 is fixedly connected to the bottom surface of the closed collar 7. The sand flowing out of the pressure sand barrel 5 directly falls into the sand ring bag 6 through the sand hole 12 under the collar. When the sand needs to be refilled, the closed collar 7 is removed from the pressure sand barrel 5, and then the sand is poured into the container, and then the closed collar 7 is installed and reset, and rotated to the position of closing the sand hole 11 under the sand barrel, and the sand in the container can be poured back into the pressure sand barrel 5 for subsequent use.

[0032] The sand holes 11 under the sand tube and the sand holes 12 under the sleeve ring are composed of three sand holes with gradually decreasing aperture sizes. The number of the sand holes 11 under the sand tube and the sand holes 12 under the sleeve ring is at least two groups. The two groups of sand holes 11 under the sand tube and the sand holes 12 under the sleeve ring are symmetrically distributed on the outer walls of the pressure-bearing sand tube 5 and the closed sleeve ring 7 respectively.

[0033] The outer wall of the pressure sand tube 5 is fixedly connected with an anti-skid ring 10 , the top inner wall of the closed ring 7 is fixedly connected with a rubber inner ring 15 , and the outer wall of the anti-skid ring 10 is slidably connected with the inner wall of the rubber inner ring 15 . Example

[0034] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the outer wall of the pressure sand tube 5 is fixedly connected with an indicator icon 9, and the top of the closed ring 7 is fixedly connected with a sand hole docking pointer 13, and the sand hole docking pointer 13 is used to indicate the overlapping area of ​​the sand hole 12 under the ring and the sand hole 11 under the sand tube.

[0035] A positioning ring 14 is fixedly connected to the outer wall of the bottom end of the pressure sand tube 5 , and the upper surface of the positioning ring 14 is movably connected to the bottom end of the closed sleeve ring 7 .

[0036] A positioning collar is fixedly connected to the outer wall of the pressure-bearing column 4 near the top, and the diameter of the positioning collar is the same as the cross-sectional diameter of the pressure-bearing sand tube 5 .

[0037] The bottom end of the pressure sand tube 5 is fixedly connected to the top end of the support frame 1 .

[0038] The working principle of this new steel structure unloading device is described in detail below.

[0039] like Figure 1-5 As shown, when in use, after the support frame 1 is installed in place, the pressure-bearing column 4 is first connected to the pressure-bearing sand tube 5, and then the detachable plate frame 3 is installed on the top of the pressure-bearing column 4. At this time, the steel structure can be hoisted to press the detachable plate frame 3. After the subsequent installation work of the steel structure is completed, the detachable plate frame 3 and the support frame 1 can be disassembled to allow the steel structure to complete the overall force.

[0040] At this time, the user can rotate the outer ring frame 16 so that the rotating outer ring frame 16 drives the closed ring 7 to rotate on the outer wall of the pressure sand tube 5. While the closed ring 7 rotates, the sand hole docking pointer 13 and the sand hole 12 under the ring rotate synchronously. As the closed ring 7 rotates, the sand hole 12 under the ring is connected to the sand hole 11 under the sand tube. At this time, the sand hole docking pointer 13 points to the center position of the indicator icon 9, and the sand in the pressure sand tube 5 begins to flow out at the maximum flow rate. Since the sand holes 12 under the ring and the sand holes 11 under the sand tube are symmetrically distributed, the sand in the pressure sand tube 5 can flow out evenly on both sides. After the sand flows out, the pressure column 4 slowly descends, and the detachable plate frame 3 also descends, so that the steel structure is unloaded.

[0041] As the unloading of the steel structure proceeds, when it approaches the target position and the outflow speed of the sand needs to be reduced, the closed ring 7 begins to rotate counterclockwise. At this time, the docking area between the sand hole 11 under the sand tube and the sand hole 12 under the ring gradually decreases, and then the outflow speed of the sand also decreases until the unloading of the steel structure is completed.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
