Description

Technical Field

[0001] This invention belongs to the technical field of coal mine pillarless mining support equipment, specifically relating to a flexible mold hanging support integrated device. Background Technology

[0002] Flexible formwork concrete gob-side retention technology is a key support technology in pillarless mining. Its gob-side support construction uses flexible formwork as a concrete pouring template, constraining the concrete formation to create a stable gob-side support structure. The installation of the flexible formwork is the core construction process; its efficiency and quality directly determine the forming effect of the gob-side support, thus affecting the stability and safety of the gob-side retention. Therefore, reducing the labor intensity of workers and improving the efficiency of flexible formwork installation remain key issues that need to be addressed in the development of flexible formwork concrete gob-side retention technology.

[0003] With technological advancements, flexible formwork installation equipment has evolved from purely manual operation to mechanization. However, existing formwork installation devices still have significant shortcomings in complex downhole conditions, making it difficult to meet the demands for efficient and safe construction. (1) The cross-sectional dimensions of the underground roadway vary greatly. Especially under complex conditions with large roadway height, workers need to use climbing equipment to complete the flexible mold hanging, which not only increases the labor intensity, but also poses a safety risk of falling from height. (2) The existing equipment lacks effective measures to correct deviations during travel, which can easily lead to the back frame running off course, causing the flexible formwork to be misaligned and requiring repeated manual adjustments, which seriously restricts construction efficiency. (3) The existing hanging formwork device is not equipped with a rear protective structure on the front frame, which poses a safety hazard to personnel.

[0004] (4) The existing hanging formwork device has no stabilizing mechanism on the top beam. During the frame shifting process, the top beam of the device will be unstable from left to right, which is not conducive to safe production.

[0005] Based on this, the development of a flexible formwork hanging support integrated device that can adapt to complex underground conditions and has the functions of correction and safe roof protection, to achieve efficient and safe mechanized formwork hanging operations, has become an urgent need to promote the further development of flexible formwork concrete roadway retention technology. Summary of the Invention

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1 As shown, a flexible mold support integrated device of the present invention includes a pair of liftable front frames 1 and a pair of liftable rear frames 2; the front frames 1 and the corresponding rear frames 2 are connected by a pushing mechanism 4. A transverse tensioning mechanism 11 is provided between the pair of front frames 1, and a side adjustment mechanism 12 is obliquely installed on the outer side of each rear frame; a mold hanging mechanism is provided on the inner side of the front frames 1 and the rear frames 2.

[0022] In the initial state, the pushing mechanism 4 is fully retracted. The operator raises the rear frame 2 to hold it against the roof of the roadway. The jack of the pushing mechanism 4 extends and pushes the front frame 1 forward to the designated position. Then, the front frame 1 rises and holds against the roof of the roadway, while the rear frame 2 is lowered to detach from the roof. The jack of the pushing mechanism 4 retracts and pulls the rear frame 2 back to the designated position, thus completing one self-moving cycle.

[0023] The distance between the two front frames 1 can be adjusted by the lateral tensioning mechanism 11 to adapt to different working conditions. The offset between the two rear frames 2 can be adjusted by the side adjustment mechanism 12 to ensure that they maintain the same spacing as the two front frames 1.

[0024] Example 2 Similar to Example 1, as Figure 1 As shown in Embodiment 2, a flexible mold hanging and supporting integrated device of the present invention also includes a pair of liftable front frames 1 and a pair of liftable rear frames 2; the front frames 1 and the corresponding rear frames 2 are connected by a pushing mechanism 4. A transverse tensioning mechanism 11 is provided between the pair of front frames 1, and a side adjustment mechanism 12 is obliquely installed on the outer side of each rear frame; a mold hanging mechanism is provided on the inner side of the front frame 1 and the rear frame 2.

[0025] like Figure 1 As shown, unlike Embodiment 1, in Embodiment 2, the flexible mold support integrated device of the present invention includes a front frame 1 comprising a front frame base 5, a front frame top beam 7, a column 10, and a top beam stabilizing mechanism 3; the front frame base 5 and the front frame top beam 7 are hinged together by the column 10 and the top beam stabilizing mechanism 3; a lateral tensioning mechanism 11 is disposed between the two front frame bases 5. The rear frame 2 comprises a rear frame base 6, a rear frame top beam 8, a column 10, and a top beam stabilizing mechanism 3; the rear frame base 6 and the rear frame top beam 8 are hinged together by the column 10 and the top beam stabilizing mechanism 3; a side adjustment mechanism 12 is disposed on the outside of the rear frame base 6.

[0026] In the initial state, the pushing mechanism 4 is fully retracted. The operator raises the column 10 and the top beam stabilizing mechanism 9 of the rear frame 2 so that the rear top beam 8 is pressed against the roof of the roadway. The jack of the pushing mechanism 4 extends and pushes the front frame 1 forward to the designated position. Then, the column 10 and the top beam stabilizing mechanism 3 of the front frame 1 are raised so that the front top beam 7 is pressed against the roof. The rear frame 2 is lowered and detached from the roof. The jack of the pushing mechanism 4 retracts and pulls the rear frame 2 back to the designated position, thus completing one self-moving cycle.

[0027] The distance between the two front frames 1 can be adjusted by the lateral tensioning mechanism 11 to adapt to different working conditions. The offset between the two rear frames 2 can be adjusted by the side adjustment mechanism 12 to ensure that they maintain the same spacing as the two front frames 1.

The rear frame 2 includes a rear frame base 6, a rear frame top beam 8, a column 10, and a top beam stabilizing mechanism 3; the rear frame base 6 and the rear frame top beam 8 are hinged together by the column 10 and the top beam stabilizing mechanism 3; the side adjustment mechanism 12 is provided on the outer side of the rear frame base 6.

[0029] like Figure 1 As shown, unlike Embodiment 2, in Embodiment 3, a flexible mold hanging support integrated device of the present invention has a protective top beam 9 hinged to one end of both the front top beam 7 and the rear top beam 8, and a protective top beam jack is provided between the protective top beam 9 and the front top beam 7 or the rear top beam 8.

[0030] The protective beam 9 can be extended by using the protective beam jack. After the protective beam 9 is extended, it can protect the roof and reduce the gap between the roof and the ceiling.

[0031] In the initial state, the pushing mechanism 4 is fully retracted. The operator raises the column 10 and the top beam stabilizing mechanism 9 of the rear frame 2 so that the rear top beam 8 is pressed against the roof of the roadway. The jack of the pushing mechanism 4 extends and pushes the front frame 1 forward to the designated position. Then, the column 10 and the top beam stabilizing mechanism 3 of the front frame 1 are raised so that the front top beam 7 is pressed against the roof. The rear frame 2 is lowered and detached from the roof. The jack of the pushing mechanism 4 retracts and pulls the rear frame 2 back to the designated position, thus completing one self-moving cycle.

[0032] The distance between the two front frames 1 can be adjusted by the lateral tensioning mechanism 11 to adapt to different working conditions. The offset between the two rear frames 2 can be adjusted by the side adjustment mechanism 12 to ensure that they maintain the same spacing as the two front frames 1.

[0033] Example 4 Similar to Example 3, as Figure 1As shown in Embodiment 4, a flexible mold hanging and supporting integrated device of the present invention also includes a pair of liftable front frames 1 and a pair of liftable rear frames 2; the front frames 1 and the corresponding rear frames 2 are connected by a pushing mechanism 4. A transverse tensioning mechanism 11 is provided between the pair of front frames 1, and a side adjustment mechanism 12 is obliquely installed on the outer side of each rear frame; a mold hanging mechanism is provided on the inner side of the front frames 1 and the rear frames 2. The front frame 1 includes a front frame base 5, a front frame top beam 7, a column 10, and a top beam stabilizing mechanism 3; the front frame base 5 and the front frame top beam 7 are hinged together by the column 10 and the top beam stabilizing mechanism 3; the transverse tensioning mechanism 11 is provided between the two front frame bases 5. The rear frame 2 includes a rear frame base 6, a rear frame top beam 8, a column 10, and a top beam stabilizing mechanism 3; the rear frame base 6 and the rear frame top beam 8 are hinged together by the column 10 and the top beam stabilizing mechanism 3; the side adjustment mechanism 12 is provided on the outer side of the rear frame base 6. Both the front top beam 7 and the rear top beam 8 are hinged to one end with a protective top beam 9, and a protective top beam jack is installed between the protective top beam 9 and the front top beam 7 or the rear top beam 8. The protective top beam jack can extend the protective top beam 9, which can protect the top plate and reduce the gap between the top and the ceiling.

[0034] Combination Figures 2 to 3 Unlike Embodiment 3, in Embodiment 4, the flexible mold hanging device of the present invention includes a lower shaping plate 13, an upper shaping plate 14, an automatic lifting mechanism 15, and multiple mold supporting mechanisms 16.

[0035] The lower shaping plate 13 and the upper shaping plate 14 are set inside the front top beam 7 and the rear top beam 8 by two rows of side-push jacks. The flexible formwork is shaped by extending the side-push jacks. After the concrete inside the flexible formwork is poured, the side-push jacks are retracted to complete the demolding.

[0036] The automatic lifting mechanism 15 includes multiple pulley blocks 17, a hydraulic motor winch 18, and a springback mechanism 19; the mold support mechanism 16 includes a mold support cylinder 20, a cylinder sleeve 21, and a fixed support plate 22.

[0037] Multiple pulley blocks 17 are arranged on the top and bottom of the upper shaping plate 14; a hydraulic motor winch 18 is placed on the outside of the front frame top beam 7 and the rear frame top beam 8, and the wire rope is connected to the rebound mechanism 19 via the pulley blocks 17, with the hydraulic motor winch 18 providing power.

[0038] The top flange of the flexible template is hung on the wire rope buckle. The flexible template is driven to rise by the hydraulic motor winch 18. The template is hung in conjunction with the support mechanism 16. After demolding, the buckle is retracted through the springback mechanism 19.

[0039] There are multiple mold support mechanisms 16; the mold support cylinder 20 is sleeved on the cylinder sleeve 21 to realize the lifting function; the cylinder sleeve is fixed to the inner side of the top beam through the fixed support plate 22.

[0040] Initially, all support mechanisms 16 are in the retracted state. During formwork installation, the top beam stabilizing mechanism 3 and the column 10 rise to support the top plate. The operator hangs the top flange of the flexible formwork onto the automatic lifting mechanism 15. Once the top flange of the flexible formwork rises to the top of the support cylinder 20, the support cylinder 20 rises, lifting the top flange of the flexible formwork to the top plate and tightly engaging with it, thus completing the formwork installation. After the flexible formwork concrete is poured, the support cylinder 20 is retracted, and the top flange of the flexible formwork automatically detaches. In conjunction with the automatic lifting mechanism 15, the formwork is then retracted via the rebound mechanism 19 after demolding. This completes the automatic formwork installation cycle.

[0041] Example 5 Similar to Example 4, as Figure 1As shown in Embodiment 5, a flexible mold support integrated device of the present invention also includes a pair of liftable front frames 1 and a pair of liftable rear frames 2; the front frames 1 and the corresponding rear frames 2 are connected by a pushing mechanism 4. A transverse tensioning mechanism 11 is provided between the pair of front frames 1, and a side adjustment mechanism 12 is obliquely installed on the outer side of each rear frame; a mold hanging mechanism is provided on the inner side of the front frames 1 and the rear frames 2. The front frame 1 includes a front frame base 5, a front frame top beam 7, a column 10, and a top beam stabilizing mechanism 3; the front frame base 5 and the front frame top beam 7 are hinged together by the column 10 and the top beam stabilizing mechanism 3; the transverse tensioning mechanism 11 is provided between the two front frame bases 5. The rear frame 2 includes a rear frame base 6, a rear frame top beam 8, a column 10, and a top beam stabilizing mechanism 3; the rear frame base 6 and the rear frame top beam 8 are hinged together by the column 10 and the top beam stabilizing mechanism 3; the side adjustment mechanism 12 is provided on the outer side of the rear frame base 6. Both the front top beam 7 and the rear top beam 8 are hinged to one end with a protective top beam 9, and a protective top beam jack is installed between the protective top beam 9 and the front top beam 7 or the rear top beam 8. The protective top beam jack allows the protective top beam 9 to extend, providing protection for the top plate and reducing the gap between the top and bottom. The formwork hanging mechanism includes a lower shaping plate 13, an upper shaping plate 14, an automatic lifting mechanism 15, and multiple formwork support mechanisms 16. The lower shaping plate 13 and the upper shaping plate 14 are set inside the front top beam 7 and the rear top beam 8 by two rows of side-push jacks. The flexible formwork is shaped by extending the side-push jacks. After the concrete inside the flexible formwork is poured, the side-push jacks are retracted to complete the demolding. The automatic lifting mechanism 15 includes multiple pulley blocks 17, a hydraulic motor winch 18, and a rebound mechanism 19; the formwork support mechanism 16 includes a formwork support cylinder 20, a cylinder sleeve 21, and a fixed support plate 22. Multiple pulley blocks 17 are arranged at the top and bottom of the upper shaping plate 14; a hydraulic motor winch 18 is placed on the outside of the front frame top beam 7 and the rear frame top beam 8, and the wire rope is connected to the rebound mechanism 19 via the pulley blocks 17. The hydraulic motor winch 18 provides power. The top flange of the flexible template is hung on the wire rope clip. The flexible template is driven to rise by the hydraulic motor winch 18, and the template is hung in conjunction with the support mechanism 16. After demolding, the clip is retracted through the rebound mechanism 19. There are multiple support mechanisms 16; the support cylinder 20 is sleeved on the cylinder sleeve 21 to realize the lifting function; the cylinder sleeve is fixed to the inside of the top beam through the fixed support plate 22.

[0042] like Figure 1 As shown, unlike Embodiment 4, in Embodiment 5, the top beam stabilizing mechanism 3 of the present invention includes a telescopic rod, a telescopic sleeve, and a telescopic box; the telescopic rod is slidably sleeved inside the telescopic sleeve, and the telescopic sleeve is slidably sleeved inside the telescopic box; the telescopic box is fixed on the front frame base 5 or the rear frame base 6; one end of the telescopic rod is fixedly connected to the front frame top beam 7 or the rear frame top beam 8.

[0043] The top beam stabilizing mechanism 3 achieves a stable connection between the base and the top beam through the extension and retraction of the telescopic rod and telescopic sleeve. In conjunction with the column 10, it ensures that the top beam will not wobble during movement and mold hanging. The top beam stabilizing mechanism 3 and the column 10 also allow for height adjustment of the top beam.

[0044] Example 6 like Figure 2 As shown, unlike Embodiment 5, in Embodiment 6, a flexible mold hanging and supporting integrated device of the present invention, both the front frame base 5 and the rear frame base 6 are provided with a working platform 23, which makes it convenient for operators to stand on them and carry out mold hanging operations.
