[0031] The self-positioning opening assembly 6 includes a first hydraulic rod 8 fixedly installed at the top of the top frame 5. The telescopic end of the first hydraulic rod 8 extends to the bottom of the top frame 5 and is fixedly connected to the clamping seat 9. The clamping seat 9 is provided with a hydraulic adjustment mechanism on two opposite sides and a drilling mechanism on the other two opposite sides.

[0032] The hydraulic adjustment mechanism includes two hydraulic side covers 16 fixedly installed on both sides of the clamping seat 9. Each hydraulic side cover 16 has a hydraulic chamber 20. The hydraulic side cover 16 below the hydraulic chamber 20 has multiple hydraulic grooves 21. The multiple hydraulic grooves 21 are connected to the hydraulic cover. Each hydraulic groove 21 has a hydraulic telescopic plate 17 slidably installed in it.

[0033] The drilling mechanism includes a centering adjustment cover 18 fixedly mounted on both sides of the clamping seat 9. Two hydraulic pipes 19 are fixed at both ends of the centering adjustment cover 18. The ends of the two hydraulic pipes 19 away from the centering adjustment cover 18 are fixedly connected to two hydraulic side covers 16. A movable column 29 is slidably connected inside the centering adjustment cover 18. A connecting rod 25 is fixedly connected to the outside of the movable column 29. A movable groove is opened on the centering adjustment cover 18. A sliding side rod 10 is fixedly connected to the end of the connecting rod 25 away from the hydraulic pipe 19. One end of the sliding side rod 10 is slidably connected to the clamping seat 9. The other end of the sliding side rod 10 is fixedly connected to a fixing sleeve 11. A second hydraulic rod 12 is fixedly connected to one end of the fixing sleeve 11. The telescopic end of the second hydraulic rod 12 extends into the fixing sleeve 11 and is fixedly connected to a drilling motor 22. The output shaft of the drilling motor 22 is coaxially fixedly connected to a drill bit 23.

[0034] The conveying mechanism includes a conveying channel set in the conveying seat 1, a conveyor belt 2 is provided in the conveying channel, and a conveying motor 4 for driving the conveyor belt 2 is fixed on the conveying seat 1.

[0035] A bearing plate 7 is fixedly installed inside the conveying channel, and the bearing plate 7 is in contact with the top surface of the inner side of the conveyor belt 2.

[0036] The conveyor belt 2 is provided with a guide plate 3 above it. There are two guide plates 3, and both guide plates 3 are fixedly connected to the conveyor seat 1.

[0037] The guide plate 3 includes an inclined plate and a straight plate. The inclined plate can guide the conveying of angle steel.

[0038] The bottom end of the clamping seat 9 is provided with a clamping groove 24.

[0039] Both ends of the movable column 29 are provided with end holes 26. A spring 27 is fixedly connected to the end of the end hole 26. The free end of the spring 27 is fixedly connected to a sliding block 28. The sliding block 28 is slidably connected to the inner wall of the end hole 26.

[0040] The side wall of the clamping seat 9 is fixedly provided with a guide rail 13, and the sliding side rod 10 is slidably connected to the guide rail 13.

[0041] Example 2

[0042] Please see Figure 1-8 The other contents of this embodiment are the same as those of embodiment 1, except that: the sliding side rod 10 is provided with a plurality of mounting holes 14, and fastening bolts 15 are provided in the mounting holes 14, and the fastening bolts 15 are threadedly connected to the connecting rod 25.

[0043] In the implementation of this invention, the conveyor motor 4 is first started, and then multiple angle steels are placed on the conveyor belt 2 in sequence, with a certain distance between two adjacent angle steels. When the angle steels move to the bottom of the pressing seat 9, the conveyor motor 4 is controlled to stop running.

[0044] Then, the first hydraulic rod 8 is extended, causing the clamping seat 9 to move downwards. The clamping seat 9 clamps and fixes the angle steel onto the conveyor belt 2 and the bearing plate 7. At this time, some of the hydraulic telescopic plates 17 inside the hydraulic side covers 16 on both sides of the clamping seat 9 are blocked by the top of the angle steel and cannot move downwards. This causes some of the hydraulic telescopic plates 17 to move towards the inside of the hydraulic groove 21, squeezing the hydraulic oil in the hydraulic groove 21 into the hydraulic chamber 20. If the clamping seat 9 is not in the center of the top of the angle steel, the number of unobstructed hydraulic telescopic plates 17 inside the hydraulic side covers 16 at both ends of the angle steel will be inconsistent, resulting in two hydraulic side covers. When the pressure inside the cover 16 is inconsistent, hydraulic oil will enter the end hole 26 and push the sliding block 28 to move. At the same time, hydraulic oil will push the movable column 29 to move, so that the pressure inside the two hydraulic side covers 16 is balanced. When the movable column 29 moves, it can drive the sliding side rod 10 and the drill bit 23 to move, so as to achieve automatic centering adjustment. If centering drilling is not required, the multiple mounting holes 14 on the sliding side rod 10 can be selected. Select the appropriate mounting hole 14, and then use the fastening bolt 15 to connect the sliding side rod 10 and the connecting rod 25.

[0045] When drilling, the second hydraulic rod 12 is extended to move the drilling motor 22 and the drill bit 23. The drilling motor 22 is started to drive the drill bit 23 to rotate, thereby realizing the hole opening process.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
