Description

Technical Field

[0001] This utility model belongs to the field of well drilling technology, and more specifically, relates to a well drilling machine. Background Technology

[0002] A well drilling rig is a type of excavation machinery that uses rotary drilling to break rocks and create holes, and can also reverse the hole to enlarge it. The United States began using well drilling rigs in 1962, and by the early 1990s, the use of drilling methods to excavate wells for various purposes in underground mines abroad was rapidly promoted, and well drilling rigs were applied with great success.

[0003] However, during drilling operations, the strong vibrations generated by the drill rig system are transmitted to the chassis, affecting it and requiring high structural strength, leading to high manufacturing and operating costs. Furthermore, the vibrations transmitted to the chassis during drilling also affect its stability, consequently impacting the drilling accuracy of the drill rig system. Utility Model Content

[0004] To address the problem that the strong vibrations generated by the drill rig system during drilling operations are transmitted to the chassis, the purpose of this invention is to provide a new type of well drilling rig. The well drilling rig includes a chassis, a drill rig system, and a separation structure. The drill rig system is detachably mounted on the chassis via the separation structure. The separation structure includes: a positioning connection part, disposed between the chassis and the drill rig system, for positioning and traction force transmission between the chassis and the drill rig system; and at least one clamping part, movably disposed on the chassis and located near the positioning connection part, for clamping and fixing the drill rig system on the chassis and for separation.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a separation structure between the frame and the drilling rig system, the frame can be temporarily separated from the drilling rig system during operation, preventing the vibration generated during drilling from being transmitted to the frame. This eliminates the impact of drilling vibration on the frame, reducing the strength requirements of the frame and achieving the goal of saving manufacturing and operating costs. Furthermore, it also improves the stability of the frame and the drilling accuracy of the drilling rig system.

[0006] Furthermore, the positioning connection includes: a first pin hole, formed on the frame; and a positioning pin, disposed on the drill frame system; wherein the positioning pin can be inserted into the first pin hole to achieve positioning and connection.

[0007] Furthermore, the clamping part includes: a pressure plate, movably mounted on the frame; and a clamping cylinder, mounted on the frame, driving the connection pressure plate.

[0008] Furthermore, two clamping parts are symmetrically arranged on both sides of the positioning connection part.

[0009] Furthermore, the well drilling rig also includes a telescopic traverse mechanism, which is installed between the drill frame system and the chassis. The drill frame system can be adjusted in position in a first direction and a second direction through the telescopic traverse mechanism. The first direction is the length direction of the chassis, and the second direction is the width direction of the chassis.

[0010] Furthermore, the well drilling rig also includes a pitch mechanism, which is located between the drill frame system and the chassis. The drill frame system can adjust the pitch angle through the pitch mechanism.

[0011] Furthermore, the well drilling rig also includes a rotary lifting mechanism, which is located between the drill frame system and the chassis. The drill frame system can achieve rotary and lifting movements through the rotary mechanism.

[0012] Furthermore, the telescopic traverse mechanism includes a telescopic part and a traverse part; the telescopic part includes a telescopic slide, a telescopic cylinder, and a telescopic arm, and the telescopic cylinder can drive the telescopic arm to slide along the telescopic slide; the traverse part includes a traverse support, a traverse cylinder, and a traverse mounting seat disposed on the telescopic arm, and the traverse cylinder can drive the traverse support to slide on the traverse mounting seat.

[0013] Furthermore, the pitch mechanism includes a pitch support, a pitch cylinder, and a pitch mounting base mounted on the telescopic traverse mechanism; wherein, the pitch cylinder can drive the pitch support to rotate relative to the pitch mounting base to achieve pitch angle adjustment.

[0014] Furthermore, the slewing lifting mechanism includes: a slewing lifting frame, a lifting cylinder, a slewing cylinder, and a slewing bearing; wherein, the slewing cylinder is mounted on the slewing lifting frame, and the cylinder drives the slewing bearing; the lifting cylinder can drive the drilling frame system to lift and lower.

[0015] The technical effects and advantages of this utility model are as follows: 1. By setting a separation structure between the chassis and the drill rig system, the chassis and drill rig system can be temporarily separated when the drill rig system is working, preventing the vibration generated during drilling from being transmitted to the chassis. This eliminates the impact of drilling vibration on the chassis, reducing the strength requirements of the chassis and achieving the goal of saving manufacturing and operating costs. On the other hand, it can also improve the stability of the chassis and the drilling accuracy of the drill rig system.

[0016] 2. The drilling frame system can adjust the drill rod by raising, lowering, rotating, tilting, lateralizing, and extending through the telescopic traverse mechanism, pitching mechanism, and rotary lifting mechanism to adapt to drilling requirements at different angles. This expands the functionality of the Tianji drilling rig, enabling it to not only perform vertical drilling but also complete complex operations such as inclined drilling. This greatly improves the equipment's adaptability to different construction needs and geological conditions, achieving "one machine for multiple uses". Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] See Figure 1 This is a structural schematic diagram of a well drilling rig provided by this utility model. Combined with... Figures 1 to 6 The well drilling rig includes, for example, a frame 10, a drill rig system 70, and a separation structure. The drill rig system 70 is detachably mounted on the frame 10 via the separation structure. The separation structure includes: a positioning connection part disposed between the frame 10 and the drill rig system 70 for positioning and traction force transmission between the frame 10 and the drill rig system 70; and at least one clamping part movably disposed on the frame 10 and located near the positioning connection part for clamping and fixing the drill rig system 70 on the frame 10 and for separation. For example, the bottom of the frame 10 is also provided with outriggers and support cylinders.

[0021] Understandably, by setting a separation structure between the frame 10 and the drill rig system 70, the frame 10 can be temporarily separated from the drill rig system 70 during operation, preventing the vibration generated during drilling from being transmitted to the frame 10. This eliminates the impact of drilling vibration on the frame 10, reducing the strength requirements of the frame 10 and achieving the goal of saving manufacturing and operating costs. On the other hand, it also improves the stability of the frame 10 and the drilling accuracy of the drill rig system 70.

[0022] In one specific embodiment, during transportation and positioning of the drill rig system 70, the drill rig system 70 is mounted on the frame 10 via a separate structure. Specifically, when the drill rig system 70 is not in operation, it is in a compact, folded state, making the entire equipment structure compact and easy to transport and move. When the drill rig system 70 is in operation, it is in an upright state, and its lifting, rotation, pitch, lateral movement, and telescopic adjustment are achieved through a telescopic traverse mechanism, a pitch mechanism, and a rotary lifting mechanism, thereby enabling precise positioning of the drill rod without moving the vehicle.

[0023] Once the drill frame system 70 is positioned and in the drilling operation, the clamping part releases the clamping force applied to the drill frame system 70, and the drill frame system 70 is temporarily separated from the frame 10. The drill frame system 70 is independently fixed to the working surface through its own support structure, effectively blocking the vibration of the drill frame system 70 during drilling operations from being transmitted to the frame 10. This eliminates the need for the frame 10 to be specially reinforced to resist drilling vibration, significantly reducing the manufacturing cost and maintenance cost of the frame 10.

[0024] Furthermore, the positioning connection includes: a first pin hole 23, which is formed on the frame 10; and a positioning pin 24, which is disposed on the drill frame system 70; wherein the positioning pin 24 can be inserted into the first pin hole 23 to achieve positioning and connection.

[0025] Furthermore, the clamping part includes: a pressure plate 22, movably mounted on the frame 10; and a clamping cylinder 21, mounted on the frame 10, driving the connection pressure plate 22. Preferably, the two clamping parts are symmetrically arranged on both sides of the positioning connection part. For example, the first pin hole 23 is a central pin hole provided on the frame 10, and the clamping parts are a left clamping part and a right clamping part provided on both sides of the central pin hole.

[0026] Understandably, the engagement of the locating pin 24 and the first pin hole 23 provides simple and reliable center positioning and strong traction transmission capability. The left and right clamping plates, in conjunction with the left and right clamping cylinders, form left and right clamping sections, providing uniform and powerful clamping force, effectively preventing the drill frame system 70 from jumping or rotating during transportation. This structure achieves an optimal balance between load-bearing capacity, ease of operation, and manufacturing cost.

[0027] In one specific embodiment, during transportation and positioning of the drill frame system 70, the left and right clamping cylinders drive the left and right pressure plates to press and fix the drill frame system 70 onto the frame 10. At this time, the positioning pin 24 is inserted into the first pin hole 23. When separation is required, the left and right pressure plates 22 are released, and the entire drill frame system 70 can be separated from the frame 10. At this time, the positioning pin 24 is dislodged from the first pin hole 23.

[0028] Furthermore, the well drilling rig also includes a telescopic traverse mechanism, which is set between the drill frame system 70 and the chassis 10. The drill frame system 70 can be adjusted in a first direction and a second direction through the telescopic traverse mechanism. The first direction is the length direction of the chassis 10, and the second direction is the width direction of the chassis 10.

[0029] Furthermore, the well drilling rig also includes a pitch mechanism, which is located between the drill frame system 70 and the chassis 10. The drill frame system 70 can adjust the pitch angle through the pitch mechanism.

[0030] Furthermore, the well drilling rig also includes a rotary lifting mechanism, which is located between the drill frame system 70 and the chassis 10. The drill frame system 70 can achieve rotary and lifting movements through the rotary mechanism.

[0031] Understandably, the drill frame system 70 can adjust the drill rod by raising, rotating, tilting, lateralizing, and extending through the telescopic traverse mechanism, pitch mechanism, and rotary lifting mechanism to adapt to drilling requirements at different angles. This expands the functionality of the Tianji drill rig, enabling it to not only perform vertical drilling but also complete complex operations such as inclined drilling. This greatly improves the equipment's adaptability to different construction needs and geological conditions, achieving "one machine for multiple uses".

[0032] Furthermore, the telescopic lateral movement mechanism includes a telescopic part and a lateral movement part; the telescopic part includes a telescopic slide 31, a telescopic cylinder 32, and a telescopic arm 33, and the telescopic cylinder 32 can drive the telescopic arm 33 to slide along the telescopic slide 31; the lateral movement part includes a lateral movement bracket 43, a lateral movement cylinder 42, and a lateral movement mounting seat 41 disposed on the telescopic arm 33, and the lateral movement cylinder 42 can drive the lateral movement bracket 43 to slide on the lateral movement mounting seat 41.

[0033] For example, the telescopic slide 31 has a hollow structure, and the cavity inside the telescopic slide 31 forms a track for the telescopic arm 33 to slide. The telescopic slide 31 is fitted with the telescopic arm 33. The bottom of the telescopic slide 31 is provided with a T-shaped structure that cooperates with the pressing part, and the positioning pin 24 is a center pin set on the lower end face of the T-shaped structure.

[0034] Furthermore, the pitch mechanism includes a pitch support 53, a pitch cylinder 52, and a pitch mounting base 51 mounted on the telescopic traverse mechanism; wherein, the pitch cylinder 52 can drive the pitch support 53 to rotate relative to the pitch mounting base 51 to achieve pitch angle adjustment. Preferably, the traverse support 43 is provided with a functional interface for the operation of the pitch mechanism.

[0035] Furthermore, the slewing and lifting mechanism includes: a slewing and lifting frame 63, a lifting cylinder 64, a slewing cylinder 62, and a slewing bearing 61; wherein, the slewing cylinder 62 is mounted on the slewing and lifting frame 63, and the cylinder drive is connected to the slewing bearing 61; the lifting cylinder 64 can drive the drill frame system 70 to lift and lower. Preferably, the pitch support 53 of the pitch mechanism provides a functional interface for the rotation of the drill frame system 70.

[0036] In one specific embodiment, the telescopic cylinder 32 is disposed on the outer wall of the telescopic slide 31 and is fixedly mounted on the telescopic slide 31. The output end of the telescopic cylinder 32 is connected to the telescopic arm 33, driving the telescopic arm 33 to extend or retract from the telescopic slide 31, thereby realizing the telescopic adjustment of the drill frame system 70 along the length direction of the frame 10. A transverse mounting seat 41 for mounting the transverse support 43 and the transverse cylinder 42 is provided on the side of the telescopic arm 33 away from the telescopic cylinder 32. The middle part of the transverse cylinder 42 is fixed on the transverse mounting seat 41, and the output ends of the transverse cylinder 42 are connected to the transverse support 43, driving the transverse support 43 to slide on the transverse mounting seat 41, thereby realizing the transverse adjustment of the drill frame system 70 along the width direction of the frame 10.

[0037] Two pitch cylinders 52 are mounted on the transverse support 43 via pitch mounting bases 51. The output end of the pitch cylinder 52 is connected to the pitch support 53. The pitch movement of the pitch support 53 is realized by the extension and retraction movement of the output end of the pitch cylinder 52, thereby realizing the pitch angle adjustment of the drill frame system 70 and the drill rod.

[0038] The pitch support 53 has a slewing mounting position. The slewing lifting frame 63 is rotatably mounted in the slewing mounting position via a slewing bearing 61 and a slewing cylinder 62. The slewing cylinder 62 can drive the slewing lifting frame 63 to rotate on the pitch support 53, thereby realizing the slewing adjustment of the drill frame system 70 and the drill pipe. The lifting cylinder 64 is located inside the drill frame system 70 and is used to realize the height adjustment of the drill frame system 70.
