DETAILED DESCRIPTION
[0030] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.
[0031] Refer to the attached Figure 1-7 As shown in FIG. 1 , a steel column core-filled adjustable lifting device in this embodiment comprises two parts, which are described in detail as follows:
[0032] The first part is the enclosure mechanism 200 for enclosing the steel column 100. Specifically, in order to facilitate construction, the enclosure mechanism 200 is assembled in a detachable manner, and can be disassembled and reassembled when the position and height of the poured steel column core are adjusted, thereby improving construction efficiency.
[0033] In this embodiment, the enclosure mechanism 200 forms an enclosure cavity located on the outer periphery of the steel column 100, which clamps and encloses the steel column 100 in the vertical direction, and then forms a clamping cavity in the horizontal direction. The pump tube 300 connected to the perfusion tube can be clamped by the clamping cavity, and then form a perfusion direction toward the inside of the steel column to complete the core filling.
[0034] The device in this embodiment can be raised and lowered, and universal wheels can be added to the bottom of the lifting mechanism to enable it to move horizontally, so that the pouring of steel columns at different positions can be carried out continuously, thereby enabling the rapid lifting and lowering of the concrete pouring port at different heights and the horizontal movement of the entire device, thereby ensuring the mobility of the steel columns in multiple positions for core pouring, thereby improving construction efficiency.
[0035] The second part, a lifting mechanism 400, is added to accommodate core filling at varying heights. This lifting mechanism 400 features a support platform 410, forming a support surface equipped with an adjustable brace 420. Connected to this brace 420 is a pipe clamp 430, which secures the pump tube 300. After being supported at a set height by the support platform 410, the pump tube 300 passes through a clamping cavity toward a steel column at a set height for core filling. The adjustable brace 420 allows for fine-tuning of the pump tube 300's height and angle on the support platform 410, while the pipe clamp 430 secures the pump tube 300, preventing any shaking during filling. A rubber pad can be added to the pipe clamp to form a protective layer to protect the pump tube.
[0036] In this embodiment, the detailed structure of each part is described as follows:
[0037] First, let's focus on the lifting mechanism 400 .
[0038] In order to facilitate welding and assembly, the lifting mechanism 400 in this embodiment includes a plurality of adjustment rods 440, and the bottom of the adjustment rods 440 is connected to a sweeping rod 450 via a pin. In this embodiment, the sweeping rod 450 is arranged near the bottom position to increase the overall stability.
[0039] Conventional sleeves are used for the adjustment rods, with the wall thickness of the multiple sections of steel pipe decreasing in sequence. Specifically, the adjustment rod 440 comprises a fixed rod 441 at the bottom, and a plurality of movable rods 442, located on the fixed rod 441 and with gradually decreasing diameters, forming a telescopic rod. The bottom of the fixed rod 441 contacts the working surface via a gasket 460. In this embodiment, the gasket 460 has a large cross-section, creating greater friction with the working surface formed by the ground, thereby improving stability. In this embodiment, the diameter of the fixed rod at the bottom is the largest, and the diameter of the movable rods decreases as it moves upward.
[0040] In order to reduce weight and ensure strength, the lifting mechanism 400 forms a frame structure, and the support platform 410 is welded to the frame structure. The frame structure not only has a lighter mass, but also can form more assembly space, providing a space foundation for subsequent other designs.
[0041] To facilitate adjustment of the relative height of the pump pipe 300 on the support platform, in this embodiment, the adjustable support 420 comprises a threaded tube that is adjustably connected to the support platform 410 via a threaded knob. In this embodiment, the adjustable support is a threaded pipe fitting with a top clamp at the top for securing the concrete pump pipe. Its lower portion is connected to the support platform via a threaded knob for adjusting the orientation and height of the pump pipe. Turning the threaded knob raises and lowers the adjustable support, simultaneously fine-tuning the height of the concrete pump pipe. Adjusting the height of the corresponding support platform significantly affects the height of the concrete pump pipe.
[0042] Specifically, the support platform 410 includes at least a solid steel plate with a cross-sectional area greater than the cross-sectional area of the enclosure mechanism 200, and part of the pump pipe 300 is supported on the solid steel plate. In this embodiment, in order to increase the load of the entire device, because the flow of concrete in the pump pipe is transported forward by the vibration of the pump pipe during concrete pouring, increasing the load of the device will ensure the overall stability during concrete pouring. At this time, the cross-sectional area of the support platform 410 is larger, thereby forming a larger support surface, which improves its bearing capacity.
[0043] In this embodiment, the support platform 410 may be provided with a plurality of lifting rings for facilitating lifting, or pulling rings for facilitating transportation.
[0044] In this embodiment, the containment mechanism 200 comprises an upper containment chamber 210 and a lower containment chamber 220. These chambers are identical in structure and are assembled by splicing, facilitating production. The formation of two upper and lower containment chambers creates two layers of restraint around the perimeter of the steel column 100. This provides increased safety compared to a single layer and facilitates the clamping of the pump tube 300.
[0045] To facilitate assembly, the upper enclosure cavity 210 includes several reinforcements that are connected end-to-end around the steel column to form an adjustable enclosure cavity. This simple splicing not only facilitates operation, but also allows the length and width to be adjusted by adding or removing reinforcements as the size of the steel column changes.
[0046] During specific assembly, a plurality of strip-shaped through holes for inserting pins are provided along the length of one side of the reinforcement piece, and a limiting groove for clamping adjacent reinforcement pieces is formed on the other side.
[0047] In order to facilitate the removal of the upper and lower enclosure chambers, hoops 230 with openings facing downward and upward are formed on the upper enclosure chamber 210 and the lower enclosure chamber 220 respectively.
[0048] Again, when the device in this embodiment is used, it can be used in all steel structure projects where hollow steel columns need to be poured with concrete, such as steel columns with a height range of 50cm to 180cm, which greatly improves construction efficiency. It has a simple structure and few consumables. It is a commonly used structure in construction, does not require too much assistance and equipment, is easy to use, and has a wide range of applications.
[0049] The device in this embodiment can be used repeatedly for pouring concrete into the core of a steel structure column. It is also simple to operate. When pouring concrete into multiple steel columns, it is only necessary to remove the fasteners and then move the lifting platform.

They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
