[0021] like Figure 1 As shown, this invention discloses a flexible mold mounting mechanism for gob-side entry retaining. The mechanism includes a front frame 1, with a first frame 10 and a second frame 3 movably mounted on both sides of the front frame 1. Two sets of vertically retractable first support mechanisms 6 are respectively mounted and fixed on the first frame 10 and the second frame 3. A casting pipe 9 is provided above the front frame 1, and multiple pipe clamps 8 are provided on the casting pipe 9. Two reciprocating drive mechanisms 13 are provided on the front frame 1, and the drive ends of the two reciprocating drive mechanisms 13 are respectively connected to the first frame 10 and the second frame 3. The drive end of each set of first support mechanisms 6 is connected to a mold mounting guide rod 7.

[0022] Limiting mechanisms 5 are respectively provided on the first frame 10 and the second frame 3. The two limiting mechanisms 5 are located below the hanging mold guide rod 7, which can prevent the hanging mold guide rod 7 from moving down excessively.

[0026] The first frame 10 and the second frame 3 are both hollow structures, which can ensure that they have large supporting strength under small weight.

[0027] In combination with Figure 3 , the maintenance team carries out hanging mold pouring. In the initial stage, the first supporting mechanism 6 is retracted, the height of the hanging mold guide rod 7 is lowered, the workers pass the multi-section flexible mold flange into the hanging mold guide rod 7, the reciprocating driving mechanism 13 is adjusted, the distance between the first frame 10 and the second frame 3 reaches the design distance, then the first supporting mechanism 6 is extended, the hanging mold guide rod 7 is pressed on the roadway roof, the hanging mold process is completed, and finally the concrete is poured into the multi-section flexible mold through the pouring port assembly, the pouring of one section of the flexible mold is completed.

[0028] In combination with Figure 3 , after the first section of the flexible mold concrete reaches a certain strength, the first supporting mechanism 6 is retracted by a certain distance, then the external driving mechanism drives the hanging mold mechanism to move forward by one step, at the same time, the 1st and 6th pipe clamps on the pouring pipe of the hanging mold mechanism are opened, the 2nd section of the multi-section flexible mold is pulled open, the first supporting mechanism 6 of the hanging mold mechanism is raised, the 6th pipe clamp is locked, the roadway support is completed, the pouring of the 2nd section of the multi-section flexible mold is carried out, and the same is repeated until the pouring of the entire flexible mold wall is completed.
