DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0023] As shown in Figures 1 to 3 The present application discloses a kind of petroleum and natural gas exploitation screw drill auxiliary dismounting equipment, including mobile platform 1, one side of the top of mobile platform 1 is hinged with rotating frame 12, one side of the top of mobile platform 1 is hinged with hydraulic cylinder 11 away from rotating frame 12, both sides of rotating frame 12 are fixed with connecting plate 121, the top of hydraulic cylinder 11 is hinged with connecting plate 121, one side of rotating frame 12 is provided with multiple groups of chuck 13; The top of mobile platform 1 is fixed with sliding roller 21, the upper of sliding roller 21 is slidably connected with counterweight 2; Wherein, when rotating frame 12 is parallel with mobile platform 1, counterweight 2 slides to the position that sliding roller 21 is located in the middle of mobile platform 1, when rotating frame 12 is perpendicular to mobile platform 1, counterweight 2 slides to the position that sliding roller 21 is located on the side of mobile platform 1 away from rotating frame 12; In the exploitation of oil and natural gas, screw drill is used, which is composed of drill pipe and drill bit. During use, the drill pipe and drill bit need to be installed together and disassembled for maintenance after use. However, due to the high weight of the drill pipe and drill bit, the auxiliary dismounting equipment is needed to fix them during dismounting. When the drill pipe and drill bit are installed, the movable platform 1 is pushed to the position of the drill pipe, and the rotating wheels at the bottom of the movable platform 1 roll on the ground. In the initial state, the rotating frame 12 is kept parallel with the movable platform 1. At this time, the hydraulic cylinder 11 pushes the connecting plate 121, and the connecting plate 121 drives the rotating frame 12 to rotate from the top end of the hydraulic cylinder 11. Then, when the rotating frame 12 is perpendicular to the movable platform 1, the hydraulic cylinder 11 stops pushing the connecting plate 121. The rotating frame 12 is provided with a mechanism capable of pushing the chuck 13. At this time, the mechanisms on both sides of the rotating frame 12 drive the two groups of chucks 13 to the sides, so that the distance between the chucks 13 is increased. Then, the workers lift the drill pipe and place it between the two chucks 13. Then, the chucks 13 are driven by the mechanisms on both sides to clamp the drill pipe. After clamping, the drill pipe is fixed on the top end of the rotating frame 12. Then, the hydraulic cylinder 11 pulls the connecting plate 121, and the connecting plate 121 is pulled to drive the rotating frame 12 to rotate towards the top end of the movable platform 1. When the rotating frame 12 is parallel to the movable platform 1, the hydraulic cylinder 11 stops running. At this time, the drill pipe is placed transversely above the movable platform 1 and is in a fixed state. At this time, the workers pick up the drill bit and install it on the end of the drill pipe by using the installation tool. The drill bit installation space is larger when the drill pipe is laid down by the rotating frame 12, which is more convenient for dismounting the screw drill. When the screw drill needs to be used, it is usually in a vertical state. At this time, the rotating frame 12 is rotated to the position close to the screw drill, and the screw drill is clamped by the chuck 13. Then, the drill and the drilling machine can be separated. At this time, the drill is fixed between the chucks 13, which can assist the drilling machine in dismounting the drill. When the chuck 13 clamps the drill, the weight of the rotating frame 12 increases, which affects the balance of the movable platform 1. The side of the movable platform 1 close to the rotating frame 12 is pressed down by the weight of the rotating frame 12, which causes the movable platform 1 to fall towards the rotating frame 12. To prevent this problem, the counterweight 2 is arranged at the top end of the movable platform 1. During use, when the rotating frame 12 is parallel to the movable platform 1, the counterweight 2 slides on the top end of the slide roller 21 to the middle position of the movable platform 1. When the rotating frame 12 is perpendicular to the movable platform 1, the counterweight 2 slides on the top end of the slide roller 21 to the position away from the rotating frame 12. At this time, the counterweight 2 can press down the end of the movable platform 1 away from the rotating frame 12. When the chuck 13 clamps the screw drill, the weight of the counterweight 2 can balance the weight on one side of the rotating frame 12, so as to maintain the stability of the movable platform 1 during use.

The contact position between the counterweight 2 and the sliding rail 21 is provided with a rolling shaft, which can reduce the friction between the counterweight 2 and the sliding rail 21, so as to facilitate the third spring 23 to drive the counterweight 2 to reset.
