In this case, the overly long filling support rod cannot fit on the top of the filling area, and instead cannot play a supporting role.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] According to an embodiment of the utility model, a filling bracket auxiliary support structure is provided, see Figures 1 to 5, including: a fixed component 1, the fixed component 1 is connected to the top beam 21 of the filling support 2; a filling support rod 3, the filling support rod 3 is hinged to the end of the fixed component 1 away from the top beam 21, and the length of the filling support rod 3 is adjustable; a rotating component 4, the rotating component 4 is connected to the fixed component 1, the rotating component 4 includes a rotating plate 41, the rotating plate 41 is located below the filling support rod 3 to support the filling support rod 3, the rotating plate 41 is rotatably arranged relative to the fixed component 1, and the rotating plate 41 rotates to drive the filling support rod 3 to rotate relative to the fixed component 1. The filling support rod 3 supports the top of the filling area behind the filling support 2 to prevent the filling area from collapsing. Due to the limitations of mining conditions, the top of the filling area is likely to be non-parallel to the horizontal plane and there is an inclined surface. The filling support rod with a certain length cannot fit on the top of the filling area at a suitable angle, but cannot play a good supporting role. By using the filling bracket auxiliary support structure of this embodiment, the rotating plate 41 is rotated. Since the rotating plate 41 supports the filling support rod 3 and the filling support rod 3 is hinged to the fixed component 1, the filling support rod 3 will also rotate relative to the fixed component 1, thereby adjusting the angle between the filling support rod 3 and the horizontal plane, so that the filling support rod 3 is more closely fitted to the top of the filling area, improving the support effect and strengthening the stability of the filling area. The filling bracket auxiliary support structure of this embodiment solves the technical problems of low fit and poor adaptability of the filling support rod to the support top in the related art.

[0029] The conventional filling support rod 3 and the top beam 21 form an integral structure, but when the integral rigid top beam is damaged, the entire top beam structure needs to be replaced, which is difficult to disassemble and install. Therefore, the fixing component 1 is connected to the top beam 21 of the filling bracket 2 in a detachable manner, which not only reduces the operating space, but also facilitates later maintenance.

[0030] See also Figure 2 In the filling bracket auxiliary support structure of this embodiment, a rotation hole 42 is provided on the rotating plate 41, and a pin 13 is provided on the fixing assembly 1. The pin 13 passes through the rotation hole 42 to hinge the fixing assembly 1 with the rotating plate 41. The rotating plate 41 rotates relative to the fixing assembly 1 with the pin 13 as the rotation center, thereby driving the filling support rod 3 to rotate, so as to increase or decrease the angle between the filling support rod 3 and the horizontal plane.

[0031] See also Figure 1In the filling bracket auxiliary support structure of this embodiment, the rotating assembly 4 also includes a jack 43, and a connecting plate 45 is provided on the side of the rotating plate 41 away from the filling support rod 3. The telescopic rod of the jack 43 is hinged to the connecting plate 45, and the other end of the jack 43 is hinged to the fixed assembly 1. The jack 43 is extended and extended to drive the rotating plate 41 to rotate relative to the fixed assembly 1. One end of the jack 43 is hinged to the fixed assembly 1, and the other end, that is, the telescopic rod, is hinged to the connecting plate 45. When the telescopic rod is extended, the connecting plate 45 is prompted to push the rotating plate 41 to rotate counterclockwise with the pin shaft 13 as the center, and the rotating plate 41 is tilted, thereby supporting the filling support rod 3 to tilt upward to increase the angle between the filling support rod 3 and the horizontal plane. When the telescopic rod contracts, the connecting plate 45 pulls the rotating plate 41 to rotate clockwise around the pin shaft 13, and the end of the rotating plate 41 away from the pin shaft 13 moves downward, driving the end of the filling support rod 3 away from the connecting part 31 to move downward, thereby reducing the angle between the filling support rod 3 and the horizontal plane.

[0032] See also Figure 2 In the filling support auxiliary support structure of the present embodiment, the rotating assembly 4 further includes a reinforcing plate 44, which is connected to the rotating plate 41 and is located between the rotating plate 41 and the filling support rod 3. In the process of the rotating plate 41 supporting and driving the filling support rod 3 to rotate, mutual friction will be generated between the two. The reinforcing plate 44 is arranged above the rotating plate 41, that is, between the rotating plate 41 and the filling support rod 3, and the reinforcing plate 44 is connected to the rotating plate 41, thereby strengthening the overall structural strength of the rotating plate 41 and improving the firmness of the rotating plate 41.

[0033] See also Figure 1 In the filling support auxiliary support structure of this embodiment, the fixing assembly 1 includes a connecting rod 11 and a fixing plate 12, the connecting rod 11 is connected to the fixing plate 12, the end of the jack 43 away from the telescopic rod is hinged to the fixing plate 12, and the filling support rod 3 has a connecting portion 31 connected to the connecting rod 11, and the connecting portion 31 is located above the rotating plate 41. The fixing plate 12 is extended along the length direction of the top beam 21, and the fulcrum (that is, the connecting portion 31) of the filling support rod 3 is above the rotating plate 41. This arrangement is convenient for the rotating plate 41 to rotate and drive the filling support rod 3 to rotate synchronously. After stopping the rotation, the rotating plate 41 still supports one end of the filling support rod 3.

[0034] See also Figure 3 , Figure 4 and Figure 5In the filling bracket auxiliary support structure of the present embodiment, the filling support rod 3 includes a first support rod 32 and a second support rod 33, the first support rod 32 and the second support rod 33 are connected, and the second support rod 33 is telescopically arranged to adjust the length of the filling support rod 3. Setting a longer filling support rod 3 has large dimensions and heavy weight. During transportation and installation, the requirements for space and hoisting are high, and the construction is difficult in the limited space of the comprehensive mining working face. Moreover, after the overall structure is damaged, the entire top beam structure needs to be replaced, and the maintenance cost is high. The first support rod 32 and the second support rod 33 are connected to form a support plate, and the overall length of the support plate is adjusted by telescoping the second support rod 33, so as to avoid the above problems.

[0035] See also Figure 3 In this embodiment, the first support rod 32 is sleeved on the second support rod 33. The end of the first support rod 32 away from the connecting rod 11 is provided with a plurality of circular holes, which are arranged at intervals along the length direction of the first support rod 32. The filling support rod 3 also includes a plurality of first locking members 34. The first locking members 34 pass through the circular holes and abut against the second support rod 33, so that the first support rod 32 is connected to the second support rod 33. When the second support rod 33 is extended into the cavity of the first support rod 32 and reaches a suitable length, the first locking member 34 passes through the circular hole and enters the first support rod 32, and abuts against the second support rod 33, so that the second support rod 33 is fixed in the first support rod 32.

[0036] See also Figure 4 and Figure 5 In this embodiment, the second support rod 33 includes a telescopic rod 331, and a through hole is provided on the telescopic rod 331. A plurality of through holes are provided on the end of the first support rod 32 away from the connecting rod 11, and each through hole is provided through the first support rod 32, and the plurality of through holes are provided at intervals along the length direction of the first support rod 32. The filling support rod 3 also includes a plurality of second locking members 35, and each second locking member 35 sequentially passes through the through hole and the through hole to connect the telescopic rod 331 with the first support rod 32, thereby connecting the first support rod 32 with the second support rod 33. The second locking member 35 is sequentially passed through the through hole on one side of the first support rod 32, the through hole on the telescopic rod 331, and the through hole on the other side of the first support rod 32, thereby fixing the telescopic rod 331 in the first support rod 32, so as to adjust the length of the filling support rod 3.

[0037] See also Figure 4 In the filling support auxiliary support structure of this embodiment, the filling support auxiliary support structure further includes an isolation component 5, which includes a base 51 and a baffle 52. The base 51 is connected to the filling support 2, and the baffle 52 is arranged perpendicular to the base 51. The baffle 52 is used to isolate the filling area. The baffle 52 is used to separate the paste injected into the filling area from the working surface to prevent the paste from flowing into the aisle.

[0038] See also Figure 4 In the filling support auxiliary support structure of the present embodiment, the isolation component 5 also includes a lifting beam 53, which is arranged perpendicular to the base 51, and the height of the lifting beam 53 is adjustable; when the filling support rod 3 supports the top of the filling area, the lifting beam 53 supports the filling support rod 3. When the filling support rod 3 is long, the torque on the overall fixing component 1 becomes larger, increasing the risk of damage to the top beam 21 and the fixing component 1 when under pressure. The lifting beam 53 arranged behind the filling support 2, on the one hand, plays a fixing role for the baffle 52, and on the other hand, the lifting beam 53 is arranged to be adjustable in height, and the height of the lifting beam 53 can also be set according to the height of the filling support rod 3, and the filling support rod 3 is supported by the lifting beam 53 to improve the stability of the support.

[0039] In this embodiment, the fixing assembly 1 and the hinged filling support rod 3 are above the aisle, one end of the filling support rod 3 is indirectly connected to the top beam 21, and the other end is supported on the lifting beam 53, providing stable support for the aisle area and effectively reducing safety risks.
