Technical Field

[0001] The utility model relates to the technical field of pit foundation supporting equipment, in particular to a pit foundation supporting device. Background Art

[0002] In the mining industry, pit foundation support technology is a key measure to ensure the safety of workers and the stability of mines during mine excavation. Deep pit support is to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. It is a support, reinforcement and protection measure adopted for the side walls of the foundation pit and the surrounding environment. It is to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. It is a support, reinforcement and protection measure adopted for the side walls of the foundation pit and the surrounding environment. The existing pit foundation support structure is mainly supported by cement retaining walls, horizontal supports, reinforced concrete piles and other methods.

[0003] Due to the complex mine environment and changing geological conditions, traditional pit foundation support methods such as wooden supports and concrete supports can no longer meet the safety and efficiency requirements of modern mining. Concrete support plates need to be poured on site when providing support. After the inner wall of the pit foundation is reinforced, the concrete support plates need to be dismantled and crushed, making it difficult to reuse. In addition, after the concrete support members are cast and formed, they are inconvenient to move and carry. Therefore, a pit foundation support device is needed to solve the above problems.

[0023] Reference Figure 1-4 A pit foundation support device includes a plate group 1, the plate group 1 includes a vertical plate 11, a support plate 2 is inserted and installed on the right side of the bottom end of the vertical plate 11, an auxiliary support plate 3 is provided above the support plate 2, the auxiliary support plate 3 includes a hanging plate 31, a side card shaft 32 is connected to the left side of the hanging plate 31, and the side card shaft 32 is embedded in the inner wall of the vertical plate 11 through a guide groove, and a reinforcement rod group 4 is provided on the top of the hanging plate 31.

[0024] A threaded pin 34 is inserted through the through hole on the surface of the hanging plate 31 , and the bottom end of the threaded pin 34 is inserted into the interior of the supporting plate 2 through the threaded hole.

[0025] The reinforcement rod group 4 includes an oblique support axis plate 41, and a bottom support block 42 is movably installed at the bottom end of the oblique support axis plate 41, and the side of the bottom support block 42 is docked and fixed with the fixing seat 33 through a locking bolt 44, and the fixing seat 33 is connected and fixed to the surface of the hanging plate 31. The top of the oblique support axis plate 41 is movably connected with a side insert plate 45, and the top of the side insert plate 45 is docked with the vertical plate 11 through a fixing accessory 46.

[0026] The bottom end of the bottom support block 42 is connected to a guide rail seat 43 , and the cross section of the guide rail seat 43 is an H-shaped structure. The guide rail seat 43 passes through the interior of the suspension plate 31 through a slot.

[0027] The fixing accessory 46 includes a docking block 461, and the side insert plate 45 is inserted into the docking block 461 on the side of the slot. A pad 463 is connected to the left side of the docking block 461, and a slider 462 is connected to the left side of the pad 463, and the slider 462 is inserted into the inner wall of the vertical plate 11 through a guide groove. Fixing bolts 464 are inserted through through holes at the corners of the pad 463, and the fixing bolts 464 are inserted into the vertical plate 11 through threaded holes. The upper and lower ends of the pad 463 are symmetrically connected to the indicator needle shaft 465.

[0028] Two hanging plates 12 are connected to the left and right sides of the top of the inner wall of the vertical plate 11 , and a connecting plate 13 is sleeved and installed on the surface of the hanging plate 12 .

[0029] Threaded holes are formed at equal intervals on the bottom end of the vertical plate 11 , and anti-slip cones 14 are inserted into the threaded holes.

[0030] When the hanging plate 31 is suspended above the support plate 2, the threaded pin 34 can pass through the through hole of the hanging plate 31 and then be inserted into the threaded hole of the support plate 2, and then the hanging plate 31 can be reinforced, so that the hanging plate 31 and the support plate 2 form a whole, thereby improving the combined stability of the vertical plate 11, the support plate 2 and the hanging plate 31, and through holes are opened at equal intervals vertically on the surface of the fixing seat 33. When the bottom support block 42 is placed on the surface of the hanging plate 31, the locking bolt 44 can pass through the bottom support block 42 and the fixing seat 33 to lock and fix it, thereby facilitating the assembly operation of the diagonal support shaft plate 41.
