[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with Figures 1 to 3 The supporting device for mining a gently inclined, broken, thin to medium-thick ore body comprises a main frame 1 , on which a supporting mechanism 2 is mounted, and an insertion end of the supporting mechanism 2 is located in the main frame 1 .

[0019] The main frame 1 includes a support column 101 and a supporting rod 102. There are two support columns 101. The top ends of the two support columns 101 are respectively fixedly connected with supporting rods 102, and one end of the two supporting rods 102 is fixedly connected. Two insertion grooves are provided on the supporting rod 102. A supporting mechanism 2 is installed on the support column 101, and the insertion end of the supporting mechanism 2 is located in the insertion groove on the supporting rod 102. The two insertion grooves on the supporting rod 102, one insertion groove is located in the middle part of the supporting rod 102, and the other insertion groove is located on one end where the two supporting rods 102 are connected.

[0020] The support column 101 and the support rod 102 may be connected by bolts, and the two support rods 102 are also connected by bolts.

[0021] The support mechanism 2 includes a first positioning frame 201 and a first support rod 202. The number of the first positioning frames 201 is two. The two first positioning frames 201 are respectively located on the two support columns 101 and are fixedly connected. The first positioning frame 201 is connected to the first support rod 202 through a connecting shaft, and one end of the first support rod 202 is fixedly connected to a connecting rod. The connecting rod on the first support rod 202 is located in one of the insertion grooves on the support rod 102 and is slidably connected.

[0022] The positions of the two first positioning frames 201 on the two supporting columns 101 are staggered.

[0023] A second positioning frame 203 is fixedly connected to the first support rod 202, and the second positioning frame 203 is connected to the second support rod 204 through a movable shaft. An insertion rod 205 is fixedly connected to one end of the second support rod 204, and the insertion rod 205 is located in another insertion groove on the support rod 102 and is slidably connected. The first positioning frame 201 and the second positioning frame 203 are both U-shaped frames, and one end of the first support rod 202 and the second support rod 204 are both in the first positioning frame 201 and the second positioning frame 203.
