[0002] With the development of economy and the improvement of living standards, people's requirements for the environment are getting higher and higher. The existing proven mineral resources are constantly consumed, and mining is developing towards deep depths. Traditional mining methods often form large goafs after mining. As time goes by, it is easy to form geological disasters such as surface collapse, mountain cracking or collapse. At the same time, traditional mining methods will leave a large number of pillars that cannot be recycled, resulting in a waste of resources. The filling mining method can solve these problems. After the ore is mined, the filling mining method uses cheap materials to fill the goaf to prevent ground collapse. The filling mining method does not need to leave pillars, so it improves the ore recovery rate, protects mineral resources, and has good economic benefits. Summary of the invention

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the present invention provides a guide rod type filling support, including a base 1, a top beam 2 and a plurality of vertically arranged hydraulic columns 3 installed between the base 1 and the top beam 2. A guide device 4 that can slide up and down is also vertically arranged on the base 1. The upper end of the guide device 4 is hinged to the top beam 2. A filling baffle 5 that can be extended and retracted up and down is also arranged at the rear of the base 1. The lower part of the filling baffle 5 is connected to the rear end of the base 1 through a connecting rod 6. The connecting rod 6 here can be a horizontally arranged jack, which can control the support position of the filling baffle 5. Since the guide device 4 in the present invention adopts a vertically arranged structure, that is, a vertical guide rod is used as a stabilizing mechanism, the structure is compact, the length of the top beam is small, the support strength is large, and it is easy to realize underground transportation.

[0028] like Figure 1 As shown, preferably, the rear plane of the filling baffle 5 is arranged parallel to the rear end of the base 1, and the filling baffle 5 includes a supporting baffle 51 and a telescopic baffle 52. The telescopic baffle 52 is installed on the supporting baffle 51 through a lifting device 53, and is hinged to the base 1 through a connecting rod 6 at the bottom end of the supporting baffle 51, which makes it easier for the bottom end of the supporting baffle 51 to contact a larger area of ​​the tunnel bottom plate; the lifting device 53 here can be a vertically arranged jack structure, the upper end of which is connected to the telescopic baffle 52. When the lifting device 53 is controlled to rise and fall, the telescopic baffle 52 moves up and down along the supporting baffle 51.

[0029] As a further preferred embodiment of the present invention, the support baffle 51 in the present invention has a chamber in which the telescopic baffle 52 can be placed. The upper end of the support baffle 51 is open, and the telescopic baffle 52 is placed into the chamber from the upper end opening of the support baffle 51. The lifting device 53 is vertically installed on the outer side of the support baffle 51, and its lower end is connected to the lower part of the support baffle 51. The upper end of the lifting device 53 is connected to the extended end of the telescopic baffle 52. Figure 1 or Figure 2 As shown, of course, the lifting device 53 can also be arranged inside the chamber, so that the upper end of the lifting device 53 is connected to the lower end of the telescopic baffle 52, and the distance that the telescopic baffle 52 extends from the upper end of the supporting baffle 51 can be controlled, and then the height of the entire filling baffle 5 can be adjusted. The present invention arranges the filling baffle 5 at the rear of the filling bracket to isolate the filling material from the working surface of the filling bracket, and arranges a telescopic baffle inside the filling baffle 5. After the telescopic baffle 52 is extended, the isolation area is increased and the filling rate is improved.

[0030] As a further preferred embodiment of the present invention, two telescopic baffles 52 are provided in the chamber of the support baffle 51, and each telescopic baffle 52 is connected to a corresponding lifting device 53, which is used to independently control the lifting and lowering of each telescopic baffle 52, and can selectively control the height of the baffle in the filling area according to the on-site conditions, so as to more flexibly match the filling process and ensure the safety of the operation. Of course, more telescopic baffles 52 can be provided in the chamber, such as three or more, which will not be described here. The connecting rod 6 in the present invention is hinged to the base 1, which can improve the adaptability of the filling bracket to the uneven bottom plate, so that the bottom of the support baffle 51 can contact the bottom plate of the working surface to the maximum extent, and prevent the filling from entering the filling bracket area from the bottom.

[0031] Further preferably, the present invention arranges two rows of hydraulic columns 3 along the front-to-back direction of the base 1, and each row is provided with two hydraulic columns 3 arranged in parallel on the left and right, that is, a total of four hydraulic columns 3 arranged perpendicular to the base are arranged, and the hydraulic columns 3 are jack structures, which can realize the synchronous lifting or lowering of the top beam. In order to increase the travel of the support top beam, the column can also be set to be inclined at a certain angle. The guide device 4 is preferably arranged between the two rows of hydraulic columns 3, and a total of two are arranged at intervals. The guide device 4 includes a hollow sleeve 41 and a guide rod 42, the lower end of the hollow sleeve 41 is fixed to the base 1, the upper end of the guide rod 42 is hinged to the lower end surface of the top beam 2, and the lower part of the guide rod 42 is installed in the hollow sleeve 41, and the two form a sliding motion pair.

[0032] In order to more effectively cover the rear filling operation area, ensure the safety of the workers, enable the filling bracket to better contact the top plate of the working surface, and improve the support capacity of the top plate, a rear flip beam 7 is hinged at the rear end of the top beam 2, and a rear flip jack 8 is provided between the top beam 2 and the rear flip beam 7, which is hinged to the two. When the rear flip jack 8 is controlled to extend and retract, the rear flip beam 7 rotates up and down relative to the top beam 2. The rotation angle of the rear flip beam 7 can be controlled in combination with the filling area to keep it in a suitable position to protect the construction workers. Figure 4 As shown, when the rear flip beam 7 is in a horizontal position, its right end is close to the filling baffle 5.

[0033] As a further preferred embodiment of the present invention, a rear telescopic beam 8 is further provided on the rear flip beam 7, and a rear telescopic jack 9 is provided between the rear flip beam 7 and the rear telescopic beam 8, which is respectively hinged to the two beams, for controlling the rear telescopic beam 8 to move forward and backward relative to the rear flip beam 7, thereby expanding the supported range of construction work behind the top beam. When the telescopic baffle 52 is in a low position, the free end of the rear telescopic beam 8 extends backward to completely cover the telescopic baffle 52. In addition, the present invention also hinges a front beam 10 at the front end of the top beam 2, and a front flip jack 20 is provided between the front beam 10 and the top beam 2, which is respectively hinged to the two beams, for controlling the front beam 10 to swing up and down along its hinged end, thereby further expanding the working range in front of the top beam 2, and at the same time improving the top connection capacity of the front end of the bracket, such as Figure 4 shown.
