Description

Technical Field

[0001] The utility model relates to the technical field of industrial building reinforcement and repair, in particular to a quick positioning and installation device for an assembled wear-resistant plate for a coal storage silo. Background Art

[0002] Due to environmental protection issues, coal cannot be stored in the open air after being mined from the ground, and can only be stored in a closed manner. Coal silos are currently the main form of coal storage.

[0003] Coal storage silos are mostly cylindrical reinforced concrete structures with a funnel-shaped bottom to facilitate the rapid discharge of coal from the lower discharge port. During silo operation, coal impacts and wears the concrete lining. To prevent this damage, a wear-resistant layer is required. Commonly used wear-resistant layers include cast stone slabs, microcrystalline boards, polymer boards, and cement-based wear-resistant materials. However, over time, the wear-resistant layer can become damaged or fall off, losing its protective effect on the concrete lining. This can lead to damage to the concrete and structural steel. If not repaired promptly, this can compromise the silo's structural safety.

[0004] The traditional method for repairing the inner wall of a concrete silo is to remove rust and restore the steel bars after the base layer is chiseled out, and then re-pour concrete or high-strength grouting for repair. There are also methods that use polymer cement mortar for repair, and then re-construct the wear-resistant layer after the repair layer hardens. These treatment methods not only have many processes, high costs, and long construction periods, but also affect the normal operation of the enterprise, causing great economic losses to the enterprise. The present utility model aims to provide a building structure that can quickly reinforce and repair the inner wall of a coal silo and has corrosion resistance and wear resistance, so as to alleviate the technical problems in the prior art that after the base layer is chiseled out, the steel bars must be removed rust and restored, and then re-pour concrete or high-strength grouting for repair. These processes are many, high in cost, and long in construction periods, and affect the normal operation of the enterprise, causing great economic losses to the enterprise. However, the existing installation device for assembled wear-resistant plates is relatively cumbersome and has many steps, resulting in a long installation period and high costs. Therefore, a quick positioning and installation device for assembled wear-resistant plates for coal storage silos is proposed. Summary of the Invention

[0025] See also Figure 1-Figure 5As shown, the utility model is a quick positioning and installation device for an assembled wear-resistant plate for a coal storage silo, comprising an upper silo 1 and a lower silo 7.

The L-shaped fixing part 2 is connected to the surface of the circumferential steel bar 5 by welding, and the circumferential steel bar 5 is connected to the circular hook fixing part 9, the bevel hook fixing part 10, and the right-angle hook fixing part 11 are all connected by welding.

[0026] In one embodiment, the fixing mechanism includes an L-shaped fixing part 2 arranged above the lower bin 7 of the coal storage silo, a circumferential steel bar 5 is fixedly connected to the top of the L-shaped fixing part 2, a circular hook fixing part 9 is fixedly connected to the side of the circumferential steel bar 5, the circular hook fixing part 9 is fixedly connected to the T-shaped connecting part 6, and a lower casting layer 8 is arranged on the periphery of the L-shaped fixing part 2.

[0027] In this embodiment, the stability of the fixed plate 4 can be ensured by providing a fixing mechanism, and the circumferential steel bars 5 are connected to the fixing mechanism, thereby further increasing the stability of the internal mechanism.

[0028] In one embodiment, for the T-shaped connector 6, the round hook fixing member 9 on the side of the T-shaped connector 6 can also be replaced with an angled hook fixing member 10 or a right-angled hook fixing member 11. A torsion spring 14 is fixedly connected to the interior of the extrusion member 15. A clamping block 12 is provided on one side of the torsion spring 14, and a threaded rod 13 is threadedly connected to the side of the clamping block 12.

[0029] In one embodiment, for the L-shaped fixing member 2, a tightening pad 16 is provided at the bottom of the L-shaped fixing member 2 for preventing the fixing plate 4 from deflecting sideways, and the T-shaped connectors 6 in the fixing mechanism are all arranged on the same horizontal plane.

[0030] In this embodiment, the tightening pad 16 provided at the bottom of the L-shaped fixing member 2 can prevent the L-shaped fixing member 2 from being welded loosely to the fixing mechanism before pouring.

[0031] In one embodiment, for the T-shaped connector 6 , a clamping block 12 is provided above the T-shaped connector 6 , and a threaded rod 13 on a side of the clamping block 12 is used to squeeze the T-shaped connector 6 .

[0032] In this embodiment, by providing a clamping block 12 above the T-shaped connector 6, shaking caused by 4 can be reduced, thereby ensuring the integrity of the pouring.

[0033] In one embodiment, for the upper silo 1 of the coal storage silo, the L-shaped fixing members 2 on the same horizontal plane inside the upper silo 1 are all fixedly connected to the annular steel bars 5 .

[0034] The working principle of the assembled wear-resistant plate rapid positioning and installation device for a coal storage silo in the utility model is as follows: first, the T-shaped connector 6 is welded with the circular hook fixing piece 9, the bevel hook fixing piece 10, and the right-angle hook fixing piece 11 in the required number, and then the base layer treatment is performed on the upper warehouse 1 of the coal storage silo, including cleaning the concrete and exposed steel bars. The base layer concrete treatment includes chiseling out the damaged concrete on the inner wall of the upper warehouse 1 of the coal storage silo and anti-corrosion treatment after the steel bars are corroded, and after chiseling, the dust, impurities, dirt, etc. on the surface of the inner wall of the coal silo are washed away. The steel bar treatment includes rust removal of the steel bars on the inner wall of the coal silo and welding of the damaged parts. According to the length and width specifications of the wear-resistant plate and the vertical wall area, the inner wall of the upper warehouse 1 of the coal storage silo is marked and lined up to determine the anchoring position of the fixed plate 4.

[0035] After the installation location is determined, begin drilling, emptying, and planting rebar along the horizontal circumference of the silo's inner wall. L-shaped fixings (2) are used for planting rebar, with the angle of the rebar being perpendicular to the silo's inner wall. The horizontal spacing of the L-shaped fixings (2) should be 1000-2000mm, and the planting depth should be 10d. In addition to being planted partially into the inner wall of the upper silo (1), a portion extending beyond the upper silo (1) should be left to adjust the fixing plate (4) so ​​that the entire structure is on a horizontal plane.

[0036] To ensure that each fixed plate 4 is neat and flat after installation without gaps, the ends of adjacent L-shaped fixings 2 should be on the same plane. During construction, a 2m level ruler can be used to calibrate whether adjacent L-shaped fixings 2 are on the same plane to ensure that the fixed plates 4 are neat and flat after final installation.

[0037] In order to ensure that the cavity casting layer is firmly bonded to the silo wall, high-expansion T-shaped rivets are installed on the vertical wall of the upper silo 1 of the coal storage silo. They are arranged in a plum blossom shape and implanted into the interior of the upper silo 1 of the coal storage silo. The spacing should be 250-300mm and the implantation depth should be 10d to increase the connection between the upper casting layer 3 and the inner wall of the upper silo 1 of the coal storage silo.

[0038] Weld the annular reinforcement 5, and perform on-site welding at the end of the intersection of each L-shaped fixing piece 2 and the horizontal annular reinforcement.

[0039] Before installing the wear-resistant plate, first install the U-shaped plate support at the bottom of the bottom layer, and use special quick sealing mortar to seal the gap between the bottom and the plate.

[0040] Then, the right-angle hook fixing member 11 of the present invention is used to hang it on the annular steel bar of the inner wall of the silo from the opening of the right-angle hook. Two T-shaped connectors 6 are set on the short side of each fixed plate 4. A total of four T-shaped connectors 6 on the upper and lower short sides of the fixed plate 4 are positioned and fixed. At the same time, between the fixed plate 4 and the upper bin 1 of the coal storage silo, a block 12 is clamped above the T-shaped connector 6 and then fastened with a threaded rod 13. Finally, the extrusion piece 15 above the torsion spring 14 is used to push the fixed plate 4 to ensure that the fixed plate 4 does not tilt inward or outward.

[0041] According to the above assembled wear-resistant plate rapid positioning installation, start pouring the upper pouring layer 3 on the fixed plate 4 and the cavity layer of the coal storage silo upper warehouse 1. After pouring is completed, the top tight pad 16 put in the previous process is taken out.

[0042] When installing the second layer of fixed plate 4, repeat the above assembled installation method and grouting process until all the construction is completed. According to the actual situation on site, the grouting of the upper pouring layer 3 can be poured one layer at a time or two layers at a time. The utility model is suitable for the reinforcement and repair project of the inner wall of the upper warehouse 1 of the existing coal storage silo. Usually, the stacking corner of the lower warehouse 7 of the coal storage silo needs to withstand a large impact force and the degree of damage is the most serious. At the same time, since the working surface of the stacking corner is irregular, this embodiment adopts a small-sized thickened fixed plate 4 of 30x800X500mm, which is prefabricated in the factory. The casting material is the lower pouring layer 8, which is used as the casting material for the cavity formed by the vertical wall of the upper warehouse 1 of the coal storage silo and the fixed plate 4.

[0043] The specific installation and pouring construction process of the wear-resistant plate is the same as that described in Example 1, specifically: cleaning the slope base of the lower bin 7 of the coal storage silo - implanting the L-shaped fixing piece 2 - implanting the high-expansion T-shaped rivet - welding the circumferential steel bar 5 - hanging the circular hook fixing piece 9 - sealing the gap - installing and fixing the fixing plate 4 - pouring the lower pouring layer 8 - cleaning the site and putting it into use.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
