When installing the support device, the bolts 5 are loosened. At this time, the second base 4 is pulled, and the limit block 3 slides inside the installation groove 2, thereby changing the distance between the two support plates 9, so that the two support plates 9 can be adjusted to the bottom of both sides of the top of the deep well. After the adjustment, the bolts 5 are tightened to fix the first base 1 and the second base 4. The first base 1 and the second base 4 are fixedly installed at the bottom of the deep well through the cooperation between the screws and the fixing plates 6. The structure is simple and easy to use.

[0020] A fixed block 7 is fixedly installed on the top of the first base 1 and the top of the second base 4, and there are two fixed blocks 7. A hydraulic cylinder 8 is fixedly installed at the center point of the top of the two fixed blocks 7. A support plate 9 is fixedly installed on the top of the two hydraulic cylinders 8. The support plate 9 is driven upward by the extension of the hydraulic cylinder 8. The support plate 9 contacts the top of the deep well, thereby effectively supporting and protecting the deep well. The extension and retraction of the hydraulic cylinder 8 can be adjusted according to the height of the deep well, thereby improving applicability.

[0021] The top of the first base 1 and the top of the second base 4 are respectively located on both sides of the outside of the two fixed blocks 7, and slide grooves 10 are opened, and the number of slide grooves 10 is four. The top of the first base 1 and the top of the second base 4 are respectively located at one end of the four slide grooves 10, and a mounting plate 11 is fixedly installed, and the number of mounting plates 11 is four. A forward and reverse screw rod 12 is rotatably installed between every two mounting plates 11 through a bearing, and the forward and reverse screw rod 12 and the fixed block 7 are rotatably installed.

The first fixing seat 15 is fixedly installed on the top of the four sliders 14, and the diagonal support rod 16 is rotatably installed inside the four first fixing seats 15 through the pin shaft. The second fixing seats 17 are rotatably installed on one end of the four diagonal support rods 16 through the pin shaft. The four second fixing seats 17 are respectively fixedly installed on the two support plates 9, and the forward and reverse screws 12 are effectively driven to rotate through the work of the motor 13. The rotation of the forward and reverse screws 12 drives the sliders 14 to move, thereby changing the distance between every two sliders 14. Due to the cooperation between the first fixing seat 15, the diagonal support rod 16 and the second fixing seat 17, the height of the support plate 9 is changed. Through the cooperation between the diagonal support rod 16 and the hydraulic cylinder 8, the support plate 9 has two support structures, which greatly improves the support strength and improves the safety.

[0022] The working principle of a deep well broken surrounding rock support device provided by the utility model is as follows:

[0023] Step 1: Different deep wells have different widths. When installing the support device, loosen the bolt 5 and pull the second base 4. The limit block 3 slides inside the installation groove 2, thereby changing the distance between the two support plates 9, making it convenient to adjust the two support plates 9 to the bottom of both sides of the top of the deep well. After the adjustment, tighten the bolt 5 to fix the first base 1 and the second base 4. Through the cooperation between the screws and the fixing plate 6, the first base 1 and the second base 4 are fixedly installed at the bottom of the deep well. The structure is simple and easy to use.

[0024] Step 2: The extension of the hydraulic cylinder 8 drives the support plate 9 to move upward, and the support plate 9 contacts the top of the deep well, thereby effectively supporting and protecting the deep well. The extension and retraction of the hydraulic cylinder 8 can be adjusted according to the height of the deep well, which improves the applicability. While the hydraulic cylinder 8 is working, the motor 13 effectively drives the forward and reverse screws 12 to rotate, and the rotation of the forward and reverse screws 12 drives the slider 14 to move, thereby changing the distance between every two sliders 14. Due to the cooperation between the first fixed seat 15, the diagonal support rod 16 and the second fixed seat 17, the height of the support plate 9 is changed. Through the cooperation between the diagonal support rod 16 and the hydraulic cylinder 8, the support plate 9 has two support structures, which greatly improves the support strength and improves the safety.

[0025] Compared with the related art, the deep well broken surrounding rock support device provided by the utility model has the following beneficial effects:

[0026] The widths of different deep wells are different. When installing the support device, the bolt 5 is loosened. At this time, the second base 4 is pulled, and the limit block 3 slides inside the installation groove 2, thereby changing the distance between the two support plates 9, making it convenient to adjust the two support plates 9 to the bottom of both sides of the top of the deep well. After the adjustment, the bolt 5 is tightened, thereby fixing the first base 1 and the second base 4. Through the cooperation between the screws and the fixing plate 6, the first base 1 and the second base 4 are fixedly installed at the bottom of the deep well. The structure is simple and easy to use.
