[0008] An airbag assembly;

[0009] A crawler mechanism, including a crawler frame, a crawler driver, crawler wheels and a crawler. The crawler driver is arranged on the crawler frame and is configured to drive the crawler wheels to rotate around their own axes. The crawler is wound around the crawler wheels. Each crawler frame is connected to the bottom support frame through an airbag assembly. When the airbag assembly inflates and deflates, it can drive the bottom support frame to move relative to the crawler mechanism in a first direction. There are multiple crawler mechanisms, and the multiple crawler mechanisms are divided into two groups. The multiple crawler mechanisms in each group are sequentially spaced along a second direction, and the two groups of crawler mechanisms are spaced in a third direction.

Compared with the configuration in which the bottom support frame is supported and moved by two crawler mechanisms, the weight of a single crawler mechanism is effectively reduced, which facilitates the transportation and maintenance of the crawler mechanism, makes the movement of the bottom support frame more flexible. On this basis, by sandwiching an airbag assembly between the bottom support frame and the crawler mechanism, the height and inclination of the bottom support frame can be adjusted by inflating or deflating the airbag assembly, avoiding the inclination and overturning of the drilling rig chassis during the operation of the drilling rig, ensuring the operation reliability and operation quality of the drilling rig. By setting the outrigger mechanism, the support span of the bottom support frame is effectively increased, and it can adapt to different terrain environments. On the basis of the airbag assembly, the lifting and deflection capabilities of the bottom support frame are further improved. Moreover, the four outrigger mechanisms cooperate with each other, enabling the entire bottom support frame to move slightly, meeting the movement requirements during continuous drilling and improving the drilling efficiency.

[0053] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0054] As Figures 1-4 shown, the present utility model provides a drilling rig chassis, including a bottom support frame 1, an airbag assembly 2, and a crawler mechanism 3. The crawler mechanism 3 includes a crawler frame 31, a crawler driver 32, crawler wheels 33, and a crawler 34. The crawler driver 32 is disposed on the crawler frame 31 and is configured to drive the crawler wheels 33 to rotate around their own axes. The crawler 34 is wound around the crawler wheels 33. Each crawler frame 31 is connected to the bottom support frame 1 through an airbag assembly 2. When the airbag assembly 2 inflates and deflates, it can drive the bottom support frame 1 to move relative to the crawler mechanism 3 in a first direction. There are multiple crawler mechanisms 3, and the multiple crawler mechanisms 3 are divided into two groups. The multiple crawler mechanisms 3 in each group are sequentially spaced at intervals in a second direction, and the two groups of crawler mechanisms 3 are spaced in a third direction. The bottom support frame 1 can move in the second direction through the multiple crawler mechanisms 3. The first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0055] In the present utility model, the bottom support frame 1 is supported and travels through multiple groups of crawler mechanisms 3. Each group of crawler mechanisms 3 includes multiple crawler mechanisms 3. Compared with the configuration in which the bottom support frame 1 is supported and travels through two crawler mechanisms 3, the weight of a single crawler mechanism 3 is effectively reduced, facilitating the transportation and maintenance of the crawler mechanism 3, making the movement of the bottom support frame 1 more flexible. On this basis, by sandwiching an airbag assembly 2 between the bottom support frame 1 and the crawler mechanism 3, the height and inclination of the bottom support frame 1 can be adjusted by inflating or deflating the airbag assembly 2, avoiding the inclination and overturning of the drilling rig chassis during drilling operations, and ensuring the operation reliability and operation quality of the drilling rig.

[0056] Specifically, there are multiple crawler wheels 33, which are respectively rotatably disposed on the crawler frame 31. The crawler 34 is wound around the multiple crawler wheels 33. The crawler driver 32 is a motor or a structure in which a motor and a gearbox are combined, and it can drive at least one crawler wheel 33 to rotate around its own axis. The more specific structure and working principle of the crawler mechanism 3 are conventional settings in the art and will not be elaborated here.

[0057] In this embodiment, the height direction of the drilling rig chassis is the first direction, the length direction is the first direction, and the width direction is the second direction.

[0058] Specifically, the bottom support frame 1 includes a longitudinal support frame 11 and two cross beams 12. Among them, the longitudinal support frame 11 extends in the second direction. The crawler frame 31 is connected to the longitudinal support frame 11 through the airbag assembly 2. The two crawler mechanisms 3 are located on opposite sides of the longitudinal support frame 11. The two cross beams 12 both extend in the third direction, and the two cross beams 12 are respectively arranged at both ends of the longitudinal support frame 11. In the structure of the above bottom support frame 1, the longitudinal support frame 11 and the two cross beams 12 are firmly connected by fasteners such as bolts, which is convenient for assembly and disassembly and flexible for transportation.

[0059] More specifically, there are four crawler mechanisms 3. Two crawler mechanisms 3 form a group, and an operation space is formed between the two crawler mechanisms 3 in each group. The bottom support frame 1 is connected to the four crawler mechanisms 3 through four airbag assemblies 2 respectively. Compared with the scheme of being supported and walking by two crawler mechanisms 3, the bottom support frame 1 can deflect while lifting, and has a stronger adaptability to the construction terrain environment.

[0060] In this embodiment, the bottom support frame 1 further includes a lateral support frame 13. The lateral support frame 13 is located in an operation space and is connected to the longitudinal support frame 11. The drilling module 100 is configured to be installed on the longitudinal support frame 11. By setting the lateral support frame 13, the operation space between the two crawler mechanisms 3 is fully utilized, the lateral support area of the bottom support frame 1 is increased, and the reliability of the overall structure is ensured on the basis of a compact layout.

[0061] Specifically, the airbag assembly 2 includes a first connection block 21, a second connection block 22 and an airbag 23. Among them, the first connection block 21 is connected to the bottom support frame 1, the second connection block 22 is connected to the crawler frame 31, and the airbag 23 is clamped between the first connection block 21 and the second connection block 22. With the above settings, the airbag assembly 2 can be more conveniently assembled between the bottom support frame 1 and the crawler mechanism 3.

[0062] In this embodiment, the first connection block 21 is connected to the longitudinal support frame 11 by fasteners such as bolts, the second connection block 22 is connected to the crawler frame 31 by fasteners such as bolts, and one or more airbags 23 can be clamped between the first connection block 21 and the second connection block 22 as needed. The airbag 23 is a conventional component in the prior art, and its structure and working principle will not be elaborated here. It is inflated by mechanisms such as an air pump. When inflated, it expands to support the corresponding connection position of the bottom support frame 1 to be raised, and when deflated, it contracts, causing the corresponding connection position of the bottom support frame 1 to be lowered.

[0063] Specifically, the drill rig chassis further includes four outrigger mechanisms 4, and the four outrigger mechanisms 4 are respectively connected to the bottom support frame 1. The bottom support frame 1 can be supported on the bearing surface through the four outrigger mechanisms 4. The outrigger mechanism 4 includes a support block 41, a swing arm 42, a boom driver 43, a support arm 44, and a support boom driver 45. Among them, the support block 41 is connected to the bottom support frame 1, one end of the swing arm 42 is rotatably connected to the support block 41, the boom driver 43 is arranged on the support block 41 and is configured to drive the swing arm 42 to rotate relative to the support block 41. One end of the support arm 44 is rotatably connected to the other end of the swing arm 42, and the other end is configured to support on the bearing surface. The support boom driver 45 is arranged on the swing arm 42 and is configured to drive the support arm 44 to rotate relative to the swing arm 42. By providing the outrigger mechanism 4, the support span of the bottom support frame 1 is effectively increased, and it can adapt to different terrain environments. On the basis of the airbag assembly 2, the lifting and deflection capabilities of the bottom support frame 1 are further improved. Moreover, the four outrigger mechanisms 4 cooperate with each other, enabling the entire bottom support frame 1 to move slightly, meeting the movement requirements during continuous drilling and improving the drilling efficiency.

[0064] More specifically, the support block 41 is rotatably connected to the bottom support frame 1, and the rotation axis of the support block 41 relative to the bottom support frame 1 is parallel to the first direction. With the above arrangement, taking the bottom support frame 1 as a reference, the outrigger mechanism 4 can extend towards multiple orientations, further improving the avoidance and adaptability.

[0065] Specifically, the support arm 44 includes a support fixed arm 441, a support movable arm 442, and a support arm driver. Among them, the support fixed arm 441 is rotatably connected to the swing arm 42, the support movable arm 442 is slidably connected to the support fixed arm 441 and is configured to support on the bearing surface. The support arm driver is arranged on the support fixed arm 441 and is configured to drive the support movable arm 442 to slide relative to the support fixed arm 441. With the above arrangement, the support arm 44 can support through its own telescoping, making the adjustment more flexible.

[0066] More specifically, the length direction of the swing arm 42 and the length direction of the support arm 44 are both parallel to the first plane, the second direction and the third direction are both parallel to the second plane, and the first plane is perpendicular to the second plane. With the above arrangement, the outrigger mechanism 4 exerts a supporting force in the direction perpendicular to the bottom support frame 1, making the support more stable and reliable.

[0067] In this embodiment, the boom driver 43, the support boom driver 45, and the support arm driver are cylinders, oil cylinders, etc. The support block 41 is rotatably connected to the cross beam 12 and can be locked with the cross beam 12 through a pin after rotational adjustment. Both the support fixed arm 441 and the support movable arm 442 are tubular structures, and the support movable arm 442 slidably penetrates through the support fixed arm 441.

[0068] Such as Figure 5 AndFigure 6 As shown in the figure, the present utility model further provides a drilling rig, which includes a drilling module 100 and the above-mentioned drilling rig chassis, and the drilling module 100 is installed on the bottom support frame 1.

[0069] In the drilling rig of the present utility model, the bottom support frame 1 is supported and moved by multiple groups of crawler mechanisms 3. Each group of crawler mechanisms 3 includes a plurality of crawler mechanisms 3. Compared with the configuration in which the bottom support frame 1 is supported and moved by two crawler mechanisms 3, the weight of a single crawler mechanism 3 is effectively reduced, which is convenient for the transportation and maintenance of the crawler mechanism 3, making the movement of the bottom support frame 1 more flexible. On this basis, by sandwiching an airbag assembly 2 between the bottom support frame 1 and the crawler mechanism 3, the height and inclination of the bottom support frame 1 can be adjusted by inflating or deflating the airbag assembly 2, avoiding the inclination and overturning of the drilling rig chassis during the operation of the drilling rig, ensuring the operation reliability and operation quality of the drilling rig. By setting the outrigger mechanism 4, the support span of the bottom support frame 1 is effectively increased, and it can adapt to different terrain environments. On the basis of the airbag assembly 2, the lifting and deflection capabilities of the bottom support frame 1 are further improved. Moreover, the four outrigger mechanisms 4 cooperate with each other, enabling the entire bottom support frame 1 to move slightly, meeting the movement requirements during continuous drilling and improving the drilling efficiency.

[0070] In this embodiment, the drilling module 100 includes a drilling bottom support base 101, a drilling adjustment base 102, and a drilling arm 103. Among them, the drilling bottom support base 101 is fixedly installed on the longitudinal support frame 11 and the lateral support frame 13. The drilling adjustment base 102 is rotatably installed on the drilling bottom support base 101, and the drilling arm 103 is rotatably installed on the drilling adjustment base 102. Hydraulic drive devices are respectively installed between the drilling bottom support base 101 and the drilling adjustment base 102, and between the drilling adjustment base 102 and the drilling arm 103. Driven by the hydraulic drive device, the drilling arm 103 can extend into another working space. The above setting makes full use of the working space between the two crawler mechanisms 3, so that during the operation, the drilling arm 103 is closer to the longitudinal support frame 11, avoiding the overturning caused by the center of gravity deviation.

[0071] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
