[0033] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] The utility model provides a rotary drilling rig in view of the fact that the ladder structure of the rotary drilling rig in the prior art is arranged at the right side of the vehicle body. If the rotary drilling rig becomes larger, there will be a safety hazard when getting on the vehicle.

[0035] Reference Figures 2 to 4 As shown, the embodiment of the present application provides a rotary drilling rig, comprising:

[0036] The operating compartment 1 is rotatably connected to the crawler 3 of the rotary drilling rig through the rotating chassis 2; the rotating chassis 2 is located on the crawler 3;

[0037] A top cover structure 4 is provided adjacent to the operating compartment 1 , and a horizontal plane of the top cover structure 4 is parallel to a horizontal plane of the rotating chassis 2 ;

[0038] A ladder frame, the ladder frame comprising two handrail frames 5 arranged opposite to each other on the top cover structure 4;

[0039] The built-in ladder 6 is arranged in the accommodation space of the fuselage 7; the accommodation space is arranged at a position adjacent to the operating cabin 1 and the top cover structure 4.

[0040] In the embodiment of the present application, the overall structure of the rotary drilling rig is divided into three parts, namely the operating cabin 1, the rotating chassis 2 and the crawler 3; the operating cabin 1 is connected to a fuselage 7, the fuselage 7 is Figure 1 The centerline L shown divides the left and right sides of the fuselage 7. The left side of the fuselage 7 is adjacent to the operating compartment 1. To avoid the safety hazards associated with a ladder structure on the right side of the fuselage, the present invention provides a storage space on the left side of the fuselage 7, adjacent to the operating compartment 1 and the top cover structure 4. A built-in ladder 6 is installed within the storage space. When not on board, the built-in ladder 6 can be concealed. The top of the storage space is protected from rain and snow, reducing the risk of rust. The top cover structure 4 is adjacent to the operating compartment 1, and its horizontal plane is parallel to the horizontal plane of the rotating chassis 2. A ladder frame is mounted on the top cover structure 4. The ladder frame includes two handrails 5 arranged opposite each other on the top cover structure 4. There is no connecting rod between the two handrails 5, and the spacing between the two handrails 5 can be adjusted as needed. The handrails 5 can also be designed with a certain curvature.

[0041] In this application, if the tonnage of the rotary drilling rig is above 50 tons, when the hydraulic oil tank continues to be on the right side of the fuselage 7, there is a problem of unsafe installation of the ladder on the right side. The rotary drilling rig of this application can also be provided with a built-in ladder 6 and a ladder frame on the left side of the fuselage 7. When getting on the vehicle, there is no need to step on the inclined structure of the crawler track 3. The built-in ladder and handrail are designed on the left side, which improves the safety of getting on the vehicle and reduces the chance of rusting of the built-in ladder.

[0042] Specifically, a first height of the handrail 5 relative to the rotating chassis 2 is greater than a second height of the built-in ladder 6 relative to the rotating chassis 2 .

[0043] In the embodiment of the present application, the first height of the handrail 5 relative to the rotating chassis 2 is greater than the second height of the built-in ladder 6 relative to the rotating chassis 2. When getting on the vehicle, get on the left side of the fuselage 7, use the built-in ladder 6 on the left side of the fuselage 7, and equip it with a ladder frame. Grab both sides of the built-in ladder 6 with both hands and continue to climb up. Grab the two handrails 5 of the ladder frame with both hands and step on the built-in ladder 6 to get on the vehicle.

[0044] Reference Figure 2 As shown, the rotary drilling rig also includes:

[0045] a side door structure 8, wherein the side door structure 8 is rotatably connected to the fuselage 7;

[0046] When the side door structure 8 is in a closed state, the side door structure 8 and the fuselage 7 form the accommodating space, and the built-in ladder 6 is completely disposed in the accommodating space.

[0047] In the embodiment of the present application, by installing the side door structure 8, the built-in ladder 6 can be effectively protected. The side door structure 8 does not need to be provided with a protruding design extending to the outside of the accommodating space, which can save space utilization. The side door structure 8 is rotatably connected to the fuselage 7 and has an open state and a closed state. In the open state, the built-in ladder 6 can be fully seen without affecting the use of the built-in ladder 6 to get on the vehicle. When the side door structure 8 is in the closed state, the side door structure 8 and the fuselage 7 form a "sealed" accommodating space. The built-in ladder 6 is completely arranged in the accommodating space, which plays a role in protecting the built-in ladder 6. The side door structure 8 and the top cover structure 4 can also be used to block rain and snow.

[0049] A door lock structure 9 is provided on the side door structure 8 .

[0050] In the present application, the door lock structure 9 is used to lock the side door structure 8 when the side door structure 8 is in a closed state, thereby preventing the side door structure 8 from opening during the operation of the rotary drilling rig and affecting the safety of the operation.

[0051] Reference Figure 3 As shown, Figure 3 for Figure 1 Optionally, the rotary drilling rig further comprises:

[0052] Multiple bolt connection structures 10 , each of the handrail frames 5 is arranged on the top cover structure 4 through multiple bolt connection structures 10 .

[0053] In an embodiment of the present application, the bolt connection structure 10 includes bolts, flat washers and spring washers. Each handrail frame 5 is fixed on the top cover structure 4 through multiple bolt connection structures 10, thereby improving the stability between the handrail frame 5 and the top cover structure 4.

[0054] Continue to refer to Figure 3 , the rotary drilling rig also includes:

[0055] Multiple fixing seats 11;

[0056] The plurality of fixing seats 11 are respectively connected to the cross section of each first connecting end of the handrail 5, and are respectively vertically connected to the cross section of the second connecting end of the built-in ladder 6;

[0057] The first connection end is the connection end between the handrail frame 5 and the top cover structure 4 ; the second connection end is the connection end between the built-in ladder 6 and the fuselage 7 .

[0058] In the embodiment of the present application, a handrail frame 5 may include two first connection ends, the cross section of each first connection end is perpendicular to a fixing seat 11, and each fixing seat 11 may be provided with at least two bolt holes. The fixing seat 11 is connected to the above-mentioned bolt connection structure 10 to improve the stability of the connection. Figure 1 As shown, the built-in ladder 6 can be provided with four fixing bases 11, which are used to fix the built-in ladder 6 with the fuselage 7. When the fixing bases 11 are provided on the top cover structure 4, the fixing bases 11 can be used to fix the top cover structure 4 and the cover structure adjacent to the top cover structure 4 at the same time.

[0059] Optionally, the fixing seat 11 is connected to the first connecting end and the second connecting end by welding or is integrally formed.

[0060] Optionally, the built-in ladder 6 includes:

[0061] A plurality of foot pedals (not shown in the figure) are provided with a plurality of anti-slip holes (not shown in the figure); wherein, on the upper end surface of the foot pedal, the edge of the anti-slip hole is higher than the foot pedal.

[0062] In the present application, by setting the anti-slip hole on the upper end surface of the foot pedal to be higher than the foot pedal, the friction between the anti-slip hole and the sole of the human shoe is increased, and the anti-slip performance of the foot pedal is improved.

[0063] Optionally, in an embodiment of the present invention, the anti-slip hole may be a gun-pressed hole, and the edge of the anti-slip hole may be higher than the foot pedal through a gun-pressing manufacturing process.

[0064] In summary, the rotary drilling rig of the present application can be loaded on the left side of the fuselage. Even if the tonnage of the rotary drilling rig is too large, it will not affect the loading effect, thereby improving the safety of loading. The present application also designs a top cover structure to prevent rain and snow, and reduce the chance of rust.
