[0029] Example 1

[0030] like Figure 1 As shown, a chassis assembly of a large deep-sea acoustic environmental protection drilling rig is provided. The chassis assembly includes a chassis frame 10, a chassis intermediate frame 20, and functional components (30, 40). The chassis intermediate frame 20 is located above the chassis frame 10. The chassis frame 10 and the chassis intermediate frame 20 are welded together to form a chassis frame, and the functional components are fixed on the chassis frame.

[0031] The functional components include a diesel tank 30 and a mast rear support 40. The diesel tank 30 is bolted to the chassis frame 10, and the mast rear support 40 is welded to the chassis frame.

[0032] The chassis assembly described in this invention adopts a layered welding method, welding the chassis frame 10 and the intermediate chassis frame 20 into a whole. This improves the rigidity of the drilling rig chassis assembly, and this structure facilitates construction, makes quality control easier, and results in a clearer overall layout and a more rational overall structure for the acoustic vibration drilling rig.

[0033] The structure of the chassis frame 10 is as follows Figures 2-3As shown in the figure, the chassis large frame 10 comprises an outer frame and a reinforcing support arranged inside the outer frame. The outer frame comprises two longitudinal beams 11 arranged in parallel and transverse beams 15 arranged at the lengthwise ends of the two longitudinal beams; the reinforcing support comprises a plurality of support beams 12 arranged between the two longitudinal beams 11 and perpendicular to the longitudinal beams 11 and connecting beams 13 arranged between adjacent support beams 12, the connecting beams 13 being perpendicular to the support beams 12. Reinforcing plates 14 are welded to the inner sides of the two longitudinal beams 11 opposite to each other, and the reinforcing plates 14 and the connecting beams 13 serve to reinforce the longitudinal rigidity of the chassis. The outer sides of the front and rear end transverse beams 15 of the chassis large frame 10 are respectively welded with connecting plates 16, which serve to connect the outrigger oil cylinders and disperse the force.

[0034] One end of the chassis large frame 10 in the length direction of the outer frame serves as the front end, and a V-shaped groove 17 recessed towards the rear end is arranged at the front end, as shown in the figure. Figure 2 The V-shaped groove 17 is arranged by cutting the transverse beam 15 at the front end in the middle, and comprises two oblique rods extending rearward from the cut-off position of the transverse beam 15 and a transverse rod at the rear end of the oblique rods. The cut-off position of the front end transverse beam 15 forms the open opening of the V-shaped groove 17.

[0035] The front end of the chassis large frame 10 adjacent to the V-shaped groove 17 is provided with a diesel tank connecting plate 18, and the diesel tank 30 is fixed to the chassis large frame 10 through the diesel tank connecting plate 18.

[0036] Specifically, the longitudinal beams 11 and the transverse beams 15 are rectangular tubes with a size of 200x100mm, the support beams 12 are square tubes with a size of 150x150mm, and the support beams 12 serve as the base for mounting the track.

[0037] The structure of the chassis middle frame body 20 is shown in the figure. Figure 4 The chassis middle frame body 20 is composed of a frame of support tubes 21, and the front end thereof comprises a left side portion and a right side portion with a space 22 therebetween, the space 22 corresponding to the position of the diesel tank connecting plate 18 so that the diesel tank 30 can be fixedly connected to the diesel tank connecting plate 18 of the chassis large frame 10 through the space 22. The left side portion is used for placing components such as hydraulic valve blocks, electrical elements and drill rod boxes, and the right side portion is used for placing components such as hydraulic oil tanks and tool boxes. Specifically, the support tubes 21 are square tubes with a size of 80x80mm.

[0038] The structure of the diesel tank 30 is shown in the figure. Figures 5-6As shown, the diesel tank 30 in the present application is separately manufactured, which facilitates the manufacture of the chassis assembly and the cleaning and surface treatment of the diesel tank body. The diesel tank 30 is welded by a bottom plate 31, a side plate 32 and a top plate 34, wherein 18 through holes are formed on the bottom plate 31, and the diesel tank 30 is fixedly connected with the diesel tank connecting plate 18 on the chassis frame 10 through bolts passing through the through holes. The top plate 34 is a bent steel plate, and a mast support 33 and a tower raising oil cylinder mounting seat 37 are welded on the top plate 34, and a front lifting lug 35 of the acoustic frequency vibration drilling machine is welded on the side plate 32, which is used as a hanging point when hoisting the drilling machine, and the installation position of the front lifting lug 35 is higher than the gravity center position of the whole drilling machine, so that the whole drilling machine can be hoisted more safely and stably. A detachable flange 36 is installed on one side of the front end of the diesel tank 30. The tower raising oil cylinder mounting seat 37 on the diesel tank is connected with the tower raising oil cylinder through a pin shaft, and the mast support 33 is connected with the mast back plate through a pin shaft. The two connecting positions on the diesel tank and the connecting points on the mast back plate form a mechanical triangle, which meets the mast raising condition after being calculated in combination with the system working pressure, the rated thrust of the oil cylinder and the like. When the mast is in the vertical state, the mast and the mast back plate are located in the V-shaped groove of the drilling machine chassis assembly.

[0039] As shown in the structure of the mast rear support, Figure 7 which comprises a vertically placed support body 41 and an obliquely arranged oblique support 42, and the oblique support 42 is arranged to make the stress of the support body 41 more reasonable.

[0040] When the drilling machine with the chassis structure is in the state that the mast is laid down, the gravity center of the whole machine is closer to the geometric center of the equipment, and the equipment is more stable during walking or hoisting. The welding positions of the front lifting lug and the rear lifting lug of the acoustic frequency vibration drilling machine are higher than the horizontal height of the gravity center of the equipment, and the equipment is more safe and stable during hoisting.

[0041] When the drilling machine with the structure is in the vertical working state of the mast, the design of the V-shaped groove makes the gravity center of the mast and the mast back plate move to the rear end of the equipment as a whole, and the gravity center of the mast is located inside the quadrilateral composed of the four supporting leg oil cylinders, so that the stability of the drilling machine is stronger during working. Due to the rear movement of the gravity centers of the mast and the diesel tank and the like, through model simulation and mathematical calculation, the stability of the drilling machine can still meet the safety coefficient requirement when the mast is in the vertical state, the front end of the walking track is used as the fulcrum, and the supporting leg oil cylinders are retracted.

[0042] The above only describes the preferred embodiments of the present application, which are only illustrative but not limiting. It is understood by those skilled in the art that many changes, modifications and even equivalents can be made to the present application within the spirit and scope defined by the claims, and all of them will fall within the protection scope of the present application.
