Description

Technical Field

[0001] The invention relates to the technical field of coal yard retaining wall height adjustment, in particular to a coal yard retaining wall heightening device for a coal-fired power plant. Background Art

[0002] In coal-fired power plants, coal yard retaining walls play a key role in storing coal. Their main function is to effectively contain and restrain coal accumulation and prevent coal from scattering to non-designated areas, thereby ensuring the safety and cleanliness of the power plant's production environment and avoiding waste of coal resources.

[0003] Traditional coal yard retaining walls are generally built by fences or solid walls of a certain height to support the coal and prevent coal from spilling out. However, with the changes in the operating needs of power plants, such as the increase in coal storage or to prevent coal from spilling out due to the coal pile exceeding the original retaining wall, it is often necessary to raise the existing coal yard retaining wall; in order to make full use of the coal yard space and improve the coal storage capacity, it may also be necessary to increase the coal pile height. However, the original retaining wall height is relatively fixed and difficult to adapt to these changes; in order to ensure the structural strength, the construction operation is usually difficult, and it is not convenient to flexibly raise or dismantle the retaining wall according to the height of the coal. In addition, due to structural limitations, traditional coal yard retaining wall heightening devices are often difficult to flexibly adjust the height and cannot be reused, which increases the operating costs of power plants, reduces resource utilization, and has obvious limitations in terms of flexibility of use.

[0004] Therefore, there is an urgent need for a coal yard retaining wall raising device for a coal-fired power plant that can be flexibly raised and dismantled. Summary of the invention

[0005] The object of the present invention is to provide a device for raising the retaining wall of a coal yard of a coal-fired power plant, which can solve the above-mentioned technical problems.

[0029] Example 1

[0030] like Figure 1-4 As shown, a device for raising the coal yard retaining wall of a coal-fired power plant includes a base 100, and a plurality of support rods 110 are fixedly connected to the bottom of the base 100. The support rods 110 are evenly distributed at the bottom of the base 100. The support rods 110 can penetrate deep into the ground to increase the friction and anchoring force between the base 100 and the ground.

[0031] Several heightening blocks 200 are sequentially inserted into the top of the base 100 from bottom to top, and docking blocks 400 are clamped between adjacent heightening blocks 200. Plug-in slots 210 are provided on both upper and lower sides of the heightening blocks 200, and the docking blocks 400 are clamped with the plug-in slots 210. U-shaped rubber protective pads 150 are provided between the upper and lower sides of the docking blocks 400 and the adjacent heightening blocks 200. The rubber protective pads 150 are sleeved on the outside of the docking blocks 400. The rubber protective pads 150 reduce the friction when the heightening blocks 200 and the docking blocks 400 are docked, and can also prevent coal particles from entering the gap between the docking blocks 400 and the heightening blocks 200 to a certain extent, avoiding the expansion of the gap due to the extrusion caused by the accumulation of coal. The rubber protective pads 150 can also play a certain role in waterproofing and moisture-proofing, reduce the corrosion of metal parts, and extend the service life of the device.

[0032] Adjacent heightening blocks 200 are connected by vertically arranged first latch rods 300. A plurality of latch grooves 230 are vertically arranged inside the heightening blocks 200. The first latch rod 300 can be inserted into the latch grooves 230. One end of the first latch rod 300 passes through the latch groove 230 of the lower heightening block 200 and the rubber protective pad 150 and is inserted into the docking block 400. The other end is inserted into the upper rubber protective pad 150 and the docking block 400. A retaining ring 310 is arranged on the outer wall of the first latch rod 300. The retaining ring 310 can be engaged with the inner wall of the latch groove 230, and the first latch rod 300 is clamped between two adjacent heightening blocks 200 to prevent the first latch rod 300 from sliding downward. The first latch rod 300 is used to connect adjacent heightening blocks 200, which improves the convenience of disassembly and assembly of the heightening blocks 200 and enhances the overall structural strength of the retaining wall. The top center of the first latch rod 300 is provided with a plug hole 330, and the bottom center of the first latch rod 300 is provided with a thin plug rod 320. The plug holes 330 and thin plug rods 320 of two upper and lower adjacent first latch rods 300 can be plugged into a whole, thereby enhancing the integrity. The length of the first latch rod 300 below the retaining ring 310 is greater than that above.

[0033] The heightening block 200 has docking grooves 220 on both sides. When setting the retaining wall, the heightening block 200 corresponds to the docking grooves 220 between the adjacent heightening blocks 200 on the left and right, and rectangular columns are installed in the docking grooves 220 of the two adjacent heightening blocks 200. The bottom of the rectangular column is inserted into the ground. By setting the rectangular column, the stable docking between the two adjacent heightening blocks 200 on the left and right can be quickly completed. The side walls on both sides of the docking block 400 are provided with rectangular handle grooves 410, which are convenient for the staff to install and remove the docking block 400.

[0034] The side wall of the docking block 400 is connected to the rubber protective pad 150 through a limiting rod, and a plurality of limiting holes 420 are horizontally arranged on the side wall of the docking block 400 and the rubber protective pad 150. The limiting rod passes through the limiting hole 420 and is horizontally arranged, and the limiting rod is spaced apart from the first latch rod 300. By setting the limiting rod, the integrity between the docking block 400 and the rubber protective pad 150 can be enhanced, and the stability of the installation structure can be improved.

[0035] A plug-in platform 140 is provided on the top of the base 100. The plug-in platform 140 is the same in shape and size as the upper half of the docking block 400. The plug-in platform 140 is plugged into the plug-in slot 210 at the bottom of the heightening block 200. The plug-in platform 140 and the heightening block 200 are connected via a second latch rod 340. The second latch rod 340 is similar in structure to the first latch rod 300. A retaining ring 310 is provided on the outer wall of the second latch rod 340, and a plug hole 330 identical to the first latch rod 300 is provided at the top center. The lower end of the second latch rod 340 passes through the latch slot 230, the rubber protective pad 150 and the plug-in platform 140 in sequence, thereby ensuring the connection stability between the base 100 and the heightening block 200.

[0036] A rubber protective pad 150 is provided between the plug-in platform 140 and the docking block 400 , and the rubber protective pad 150 and the plug-in platform 140 are also connected via a limiting rod.

[0037] Trapezoidal grooves 120 are provided on the left and right sides of the base 100 . Trapezoidal blocks 130 are provided in the trapezoidal grooves 120 . The trapezoidal blocks 130 can slide along the trapezoidal grooves 120 . The left and right adjacent bases 100 can be plugged in through the trapezoidal blocks 130 and the trapezoidal grooves 120 .

[0038] Working principle:

[0039] When in use, a deep groove is opened on the target ground where a retaining wall is set in the coal yard of a coal-fired power plant. The depth of the deep groove is 2 meters. The support rod 110 is buried in the deep groove, the base 100 is fixed, and the position of the base 100 is adjusted to be flush with the ground. Then, a rubber protective pad 150 is sleeved on the top of the docking station 140, and the limit rod passes through one side of the rubber protective pad 150 and the other side of the docking station 140 and the rubber protective pad 150 to fix and limit the rubber protective pad 150 and the docking station 140; then, the heightening block 200 is installed, and the lower end of the second latch rod 340 passes through the latch slot 230, the rubber protective pad 150 and the docking station 140 in turn, thereby ensuring the connection stability between the base 100 and the heightening block 200.

[0040] Then install the rubber protective pad 150, the docking block 400, the rubber protective pad 150 and the heightening block 200 in sequence, the lower end of the first latch rod 300 passes through the latch groove 230 of the lower heightening block 200, the rubber protective pad 150 is inserted into the docking block 400, the thin insertion rod 320 at the bottom of the first latch rod 300 is inserted into the top hole 330 of the second latch rod 340, and then repeat the operation, plugging in layer by layer in sequence until the target height is assembled.

[0041] Adjacent bases 100 are connected by inserting the trapezoidal blocks 130 and the trapezoidal grooves 120 , so that the retaining wall can be assembled to a target width.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
