DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 The hydraulic device shown is an auxiliary drilling tower lifting device, comprising a base plate 1, a pad plate 2 is fixedly installed on the left end of the base plate 1, a first axle seat 3 is fixedly installed on the right side of the pad plate 2, a tower lifting hydraulic cylinder 4 is rotatably connected to the first axle seat 3, and a first connecting ear 5 is fixedly connected to the tower lifting hydraulic cylinder 4; a plurality of adjusting hydraulic cylinders 6 are fixedly installed on the right side of the first axle seat 3, a support plate 7 is fixedly connected to the adjusting hydraulic cylinder 6, a support frame 8 is fixedly connected to the support plate 7, and a second connecting ear 9 is fixedly connected to the top of the support frame 8; a second axle seat 10 is fixedly connected to the right side of the adjusting hydraulic cylinder 6.

[0019] The bottom plate 1 includes an upper plate 11, a reinforcement plate 12 and a lower plate 13, which are connected in sequence from top to bottom, and the brackets on the reinforcement plate 12 are fixedly connected in a triangular shape, and the design of this structure makes the bottom plate 1 more stable. The support plate 7 can adopt the same structure as the bottom plate 1.

[0020] There are two pads 2, and the height of the pads 2 is the distance from the bottom of the outer surface of the tower hydraulic cylinder 4 to the upper surface of the upper plate 11 when the tower hydraulic cylinder 4 is placed horizontally. The pads 2 are used to support one end of the cylinder body of the tower hydraulic cylinder 4 when the tower hydraulic cylinder 4 is placed horizontally.

[0021] There are two first shaft seats 3, and a rotating shaft 14 is connected between the two first shaft seats 3. One end of the cylinder body of the tower lifting hydraulic cylinder 4 is fixedly connected to the rotating shaft 14, and one end of the piston rod of the tower lifting hydraulic cylinder 4 away from its cylinder body is fixedly connected to the first connecting ear 5.

[0022] The first shaft seat 3 coincides with the center line 15 of the pad 2, so that the tower lifting hydraulic cylinder 4 can be accurately placed on the pad.

[0023] The bottom of the cylinder body of the adjusting hydraulic cylinder 6 is fixedly connected to the upper plate 11 , and one end of the piston rod of the adjusting hydraulic cylinder 6 away from the cylinder body is fixedly connected to the bottom of the supporting plate 7 .

[0024] The brackets on the support frame 8 are fixedly connected in a triangular shape, and this structural design makes the support frame 8 more stable.

[0025] like Figure 2 As shown, a first mounting seat 17, a second mounting seat 18 and a lower supporting ear 19 are fixedly mounted on the lower leg 16 of the drilling tower. When in use, the first connecting ear 5 is connected to the first mounting seat 17 through a pin, and the second connecting ear 9 is connected to the second mounting seat 18 through a pin. The lower leg 16 is lifted by adjusting the tower lifting hydraulic cylinder 4.

[0026] like Figure 3 As shown, after the drilling tower is vertical, due to the different inclination angles 20 of the lower support legs 16, the lower support ears 19 cannot be aligned with the second shaft seat 10. At this time, the lower support ears 19 are aligned with the second shaft seat 10 by adjusting the hydraulic cylinder 6, and the lower support ears 19 are fixed to the second shaft seat 10 by the locking device, and the drilling tower is raised.
