Technical Field

[0001] The utility model relates to the technical field of coal conveying lines in power plants, in particular to a steel structure quick assembly structure for coal conveying lines in power plants. Background Art

[0002] The steel structure of the coal transportation line of a power plant is an important part of the coal transportation system of the power plant. It is mainly responsible for the transportation of coal. Its design, manufacture and installation need to take into account the actual situation of the power plant, the characteristics of coal and the operation requirements of the coal transportation line. During the construction of the steel structure of the coal transportation line, it is necessary to follow certain construction processes and technical specifications. First, conduct on-site surveys and equipment commissioning to ensure that the construction conditions meet the requirements. Then, formulate a detailed construction plan, including hoisting plans, process arrangements, safety precautions, etc. Then, temporarily support and fix the steel structure to ensure the stability of the hoisting process. However, the existing coal transportation line steel structure is more complicated to assemble with the support columns during the hoisting process. The screw holes on the coal transportation line steel structure need to be docked with several bolts on the support columns. The position needs to be constantly adjusted during docking, which creates installation risks.

[0003] To this end, we propose a rapid assembly structure for the steel structure of the coal transportation line of a power plant. Utility Model Content

[0004] The utility model aims to provide a quick-assembly structure of a steel structure of a coal transportation line of a power plant, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick assembly structure of a steel structure of a coal transportation line in a power plant, comprising: a support column, a conical mushroom column and an adjustment mechanism, the top of the support column is fixedly connected to a mounting plate, a liftable bolt group is equidistantly installed on the mounting plate, the conical mushroom columns are symmetrically installed on the mounting plate, a steel structure frame of the coal transportation line is placed on the two mounting plates, the bottom end of the steel structure frame is located on one side of the mounting plate and a corresponding groove is opened at the position corresponding to the conical mushroom column, an adjustment mechanism is installed inside the mounting plate, and the adjustment mechanism is installed in coordination with the conical mushroom column.

[0006] Preferably, the adjustment mechanism comprises: a turntable, a connecting seat symmetrically installed on the top of the mounting plate, the interior of the connecting seat is hollow in design, the turntable is rotatably connected to the inner wall of the connecting seat, the bottom of the turntable is fixedly connected to a worm gear, the interior of the connecting seat is rotatably connected to a worm, the worm gear is meshingly connected to the worm gear, the inside of the turntable is provided with inclined grooves equidistantly, a sliding groove is provided at the top of the connecting seat, an arc-shaped support block is slidably connected to the inside of the sliding groove, the bottom end of the arc-shaped support block is fixedly connected to an extension rod, and the extension rod is slidably connected to the inner wall of the inclined groove.

[0007] Preferably, a plurality of the arc-shaped support blocks are located at the bottom end of the conical mushroom column and are tangent to the upper surface of the conical mushroom column.

[0008] Preferably, lifting grooves are symmetrically provided at the top of the mounting plate, a threaded rod is rotatably connected to the inner wall of the lifting groove, the inner wall of the lifting groove is slidably connected to the bolt group, and the threaded rod is threadedly connected to the bolt group.

[0009] Preferably, the bottom end of the threaded rod extends out of the mounting plate and is fixedly connected to a hexagonal block.

[0010] Preferably, one end of the worm extends out of the mounting plate and is provided with a hexagonal groove.

[0011] Preferably, the edges of the corresponding grooves are rounded.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In practical application, the steel structure frame needs to be hoisted to the designated position first. Then, the two corresponding grooves on the steel structure frame are docked with the conical mushroom column. Since the diameter of the conical mushroom column is smaller than the size of the corresponding groove, the docking process does not require overly precise adjustment, which is very convenient.

[0014] Next, by turning the worm, the worm will drive the worm wheel to rotate. The worm wheel further drives the turntable to rotate, so that the inclined slot can move the extension column to slide in the slot; during this process, the arc-shaped support blocks will move away from each other under the action of the inclined slot and gradually open the corresponding slot. As the outer edge of the arc-shaped support block continues to contact and open the corresponding slot, the steel structure frame will continuously adjust its position;

[0015] When the outer edges of several arc-shaped support blocks are completely tangent to the steel structure frame, it means that the steel structure frame has been adjusted to the best position. At this time, just turn the threaded rod, and the bolt group will extend from the screw hole and be fixedly connected to the steel structure frame, thus completing the entire installation process;

[0016] This design not only realizes the rapid assembly between the support columns and the steel structure frame, but also greatly reduces the risks during the installation process and improves work efficiency. The entire operation process is simple and smooth, providing strong technical support for the construction of the power plant coal transportation line. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle:

[0029] In practical application, the steel structure frame 5 needs to be hoisted to a designated position first. Then, the two corresponding grooves 6 on the steel structure frame 5 are docked with the conical mushroom column 4. Since the diameter of the conical mushroom column 4 is smaller than the size of the corresponding groove 6, the docking process does not require overly precise adjustment, which is very convenient.

[0030] Next, by rotating the worm 74, the worm 74 drives the worm wheel 73 to rotate. The worm wheel 73 further drives the turntable 72 to rotate, so that the inclined slot 75 can move the extension column to slide in the slide slot 76; in this process, the arc-shaped support blocks 77 will move away from each other under the action of the inclined slot 75, and gradually open the corresponding slot 6. As the outer edge of the arc-shaped support block 77 continues to contact and open the corresponding slot 6, the steel structure frame 5 will continuously adjust its position;

[0031] When the outer edges of the arc-shaped support blocks 77 are completely tangent to the steel structure frame 5, it means that the steel structure frame 5 has been adjusted to the optimal position. At this time, just turn the threaded rod 9, and the bolt group 3 will extend from the screw hole and be fixedly connected to the steel structure frame 5, thereby completing the entire installation process;

[0032] This design not only realizes the rapid assembly between the support column 1 and the steel structure frame 5, but also greatly reduces the risk during the installation process and improves work efficiency. The entire operation process is simple and smooth, providing strong technical support for the construction of the power plant coal transportation line.
