Description

Technical Field

[0001] This utility model relates to the field of self-propelled drilling rig technology, specifically a highly stable self-propelled drilling rig. Background Technology

[0002] A self-propelled drilling rig is a mobile drilling device that integrates functions such as walking, drilling, and slag removal. It is mainly used in the fields of construction, engineering, and resource development. A self-propelled drilling rig is a mobile device that uses a vehicle-mounted chassis or a tracked chassis and is equipped with a drilling system (such as rotary table type, auger type, etc.). It can autonomously complete operations such as drilling, slag removal, and moving the borehole position.

[0003] In actual use, existing self-propelled drilling rigs are not stable enough when traveling on uneven roads with different roadbed heights and relatively large elevation differences, making them prone to overturning and affecting operational safety.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a highly stable self-propelled drilling rig. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable self-propelled drilling rig to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable self-propelled drilling rig, comprising a drilling rig base, an auxiliary support assembly, and a slope climbing and anti-tipping assembly. A turntable assembly is installed on the upper side of the drilling rig base, and track wheels are installed on both the left and right sides of the drilling rig base. Side plates are fixed above the left and right sides of the drilling rig base, and a first hydraulic telescopic rod is installed on the lower side of the side plates. An auxiliary support assembly is fixed below the first hydraulic telescopic rod, and the auxiliary support assembly includes a mounting frame, a movable shaft, auxiliary wheels, and a scraper. The auxiliary wheels are rotatably mounted inside the mounting frame via the movable shaft, and the auxiliary wheels are evenly distributed. A scraper is provided on one side of each auxiliary wheel, and the scraper is fixedly connected to the inner wall of the mounting frame. A slope climbing and anti-tipping assembly is installed on the rear side of the drilling rig base.

[0007] Furthermore, the turntable assembly includes a support shaft and a turntable body. The turntable body is fixed to the upper side of the support shaft, and the turntable body is rotatably connected to the drilling rig base through the support shaft.

[0008] Furthermore, the turntable assembly also includes a limiting frame and a limiting groove. The upper side of the drilling rig base is fixed with a limiting frame, which has a ring-shaped structure. The limiting frame is located outside the supporting rotating shaft, and a limiting groove is formed on the surface of the limiting frame.

[0009] Furthermore, the turntable assembly also includes sliding support rods, with sliding support rods fixed to the lower sides of both sides of the turntable body, and the sliding support rods are slidably connected to the limiting grooves.

[0010] Furthermore, a driver's cab is installed on the upper rear side of the turntable body, and a guide rail is fixed on the upper front side of the turntable body, with a drill assembly installed on the inner side of the guide rail.

[0011] Furthermore, the slope climbing anti-tipping component includes a rear plate and a second hydraulic telescopic rod. The rear plate is fixedly connected to the drilling rig base, and two second hydraulic telescopic rods are symmetrically installed below the rear plate.

[0012] Furthermore, the climbing anti-tipping assembly also includes a lifting frame, a rotating shaft, and a rear wheel. The bottom of the second hydraulic telescopic rod is fixed with a lifting frame, and the rear wheel is rotatably mounted on the inner side of the lifting frame via the rotating shaft.

[0013] This utility model provides a highly stable self-propelled drilling rig, which has the following beneficial effects:

[0014] This utility model is equipped with an auxiliary support component. The height of the mounting frame on one side of the drilling rig base can be easily adjusted by the first hydraulic telescopic rod, so that the auxiliary wheel inside the mounting frame can be in contact with the ground. It is suitable for road surfaces with different roadbed heights on both sides. The auxiliary wheel can rotate in coordination with the drilling rig base and track wheels while they are moving, thereby improving the stability of the drilling rig base during movement and preventing rollover to a certain extent. In addition, the mud scraper on one side of the auxiliary wheel can scrape mud during rotation, avoiding excessive dirt from adhering to the surface of the auxiliary wheel.

[0015] This utility model is equipped with a climbing and anti-tipping component. Two second hydraulic telescopic rods facilitate the adjustment of the height of the lifting frame on the rear side of the drilling rig base, so that the rear wheels inside the lifting frame can be in contact with the ground. This is suitable for the drilling rig base to climb slopes. The rear wheels can rotate through the rotating shaft. At this time, the rotation of the rear wheels supports the ground, which can improve the stability of the drilling rig base when climbing slopes and prevent the drilling rig base from tilting too far back. The track wheels are used to drive the movement of the drilling rig base. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-2 As shown, a highly stable self-propelled drilling rig includes a drilling rig base 1, an auxiliary support assembly 6, and a climbing and anti-tipping assembly 8. A turntable assembly 2 is mounted on the upper side of the drilling rig base 1, and track wheels 7 are mounted on both the left and right sides of the drilling rig base 1. The turntable assembly 2 includes a support shaft 201 and a turntable body 202. The turntable body 202 is fixed to the upper side of the support shaft 201, and the turntable body 202 is rotatably connected to the drilling rig base 1 through the support shaft 201. The turntable assembly 2 also includes a limiting frame 203 and a limiting groove 204. The limiting frame 203 is fixed to the upper side of the drilling rig base 1, and the limiting frame 203 has a ring-shaped structure. The limiting frame 203 is located outside the support shaft 201, and the surface of the limiting frame 203 has a limiting groove 204. The turntable assembly 2 also includes a sliding support rod 205, and the two sides of the turntable body 202... Sliding support rods 205 are fixed on the lower side, and the sliding support rods 205 are slidably connected to the limiting grooves 204. The driver's cab 3 is installed on the upper rear side of the turntable body 202, and the guide rail 9 is fixed on the upper front side of the turntable body 202. The drill assembly 10 is installed on the inner side of the guide rail 9. The track wheel 7 is used to drive the movement of the drill base 1. The drive mechanism embedded in the drill base 1 can drive the rotation of the support shaft 201 and the turntable body 202, thereby facilitating the adjustment of the direction of the guide rail 9 and the drill assembly 10. The drill assembly 10 is used for drilling operations. During the rotation of the turntable body 202, the two sliding support rods 205 on both sides can slide inside the limiting grooves 204 of the limiting frame 203, thereby improving the rotational stability of the turntable body 202 while providing force support for the turntable body 202.

[0022] like Figure 1 and Figure 3As shown, side plates 4 are fixed to the upper left and right sides of the drilling rig base 1, and a first hydraulic telescopic rod 5 is installed on the lower side of the side plate 4. An auxiliary support assembly 6 is fixed below the first hydraulic telescopic rod 5. The auxiliary support assembly 6 includes a mounting frame 601, a movable shaft 602, an auxiliary wheel 603, and a scraper 604. The auxiliary wheel 603 is rotatably mounted inside the mounting frame 601 through the movable shaft 602, and the auxiliary wheels 603 are evenly distributed. A scraper 604 is provided on one side of the auxiliary wheel 603, and the scraper 604 is fixedly connected to the inner wall of the mounting frame 601. The height of the mounting frame 601 on one side of the drilling rig base 1 can be easily adjusted by the first hydraulic telescopic rod 5, so that the auxiliary wheel 603 inside the mounting frame 601 can be in contact with the ground. This is suitable for road surfaces with different roadbed heights on both sides. While the drilling rig base 1 and the track wheel 7 are moving, the auxiliary wheel 603 can rotate in coordination, thereby improving the stability of the drilling rig base 1 during movement and preventing rollover to a certain extent. In addition, the mud scraper 604 on one side of the auxiliary wheel 603 can scrape mud from it during rotation, avoiding excessive dirt from adhering to the surface of the auxiliary wheel 603.

[0023] like Figures 1-2 As shown, a climbing and anti-tipping assembly 8 is installed on the rear side of the drilling rig base 1. The climbing and anti-tipping assembly 8 includes a rear plate 801 and a second hydraulic telescopic rod 802. The rear plate 801 is fixedly connected to the drilling rig base 1, and two second hydraulic telescopic rods 802 are symmetrically installed below the rear plate 801. The climbing and anti-tipping assembly 8 also includes a lifting frame 803, a rotating shaft 804, and a rear wheel 805. The lifting frame 803 is fixed to the bottom of the second hydraulic telescopic rod 802, and the rear wheel 805 is rotatably installed on the inner side of the lifting frame 803 through the rotating shaft 804. The two second hydraulic telescopic rods 802 facilitate the adjustment of the height of the lifting frame 803 on the rear side of the drilling rig base 1, so that the rear wheel 805 inside the lifting frame 803 can be in contact with the ground, which is suitable for the process of the drilling rig base 1 climbing. The rear wheel 805 can rotate in cooperation with the rotating shaft 804. At this time, the rear wheel 805 rotates and supports the ground, which can improve the stability of the drilling rig base 1 when climbing and prevent the drilling rig base 1 from tilting too far back.

[0024] In summary, as Figures 1-3 As shown, this highly stable self-propelled drilling rig, when in use, firstly, the track wheels 7 can drive the drilling rig base 1 to move. During movement, the height of the mounting frame 601 on one side of the drilling rig base 1 can be adjusted by raising and lowering the first hydraulic telescopic rod 5, so that the auxiliary wheel 603 inside the mounting frame 601 can be in contact with the ground. This is suitable for road surfaces with different roadbed heights on both sides. Then, while the drilling rig base 1 and the track wheels 7 are moving, the auxiliary wheel 603 can rotate in coordination, thereby improving the stability of the drilling rig base 1 during movement and preventing it from tipping over. In addition, during the rotation of the auxiliary wheel 603, the scraper 604 on one side can scrape mud off it, avoiding excessive dirt adhering to the surface of the auxiliary wheel 603.

[0025] In addition, during the process of the drilling rig 1 climbing the slope, the height of the lifting frame 803 on the rear side of the drilling rig 1 can be adjusted by raising and lowering the two second hydraulic telescopic rods 802, so that the rear wheel 805 inside the lifting frame 803 can be in contact with the ground. The rear wheel 805 can rotate through the rotating shaft 804. At this time, the rotation of the rear wheel 805 supporting the ground can improve the stability of the drilling rig 1 when climbing the slope and prevent the drilling rig 1 from tilting too far back.

[0026] During drilling operations, the drive mechanism embedded in the drill rig base 1 drives the rotation of the support shaft 201 and the turntable body 202, thereby adjusting the direction of the guide rail 9 and the drill assembly 10. The drill assembly 10 is then used for drilling operations. During the rotation of the turntable body 202, the two sliding support rods 205 on both sides can slide inside the limiting groove 204 of the limiting frame 203, thereby improving the rotational stability of the turntable body 202 while providing force support. This completes the operation of the highly stable self-propelled drilling rig.
