[0002] As is known, a slope anchor drilling rig is a special drilling equipment widely used in geological engineering, mainly used for the reinforcement and support of slopes; there are many types of slope anchor drilling rig structures on the market, among which the self-propelled anchor drilling rig is convenient and efficient to use and is very popular; the existing self-propelled anchor drilling rig mainly includes a crawler chassis and a drilling rig platform, the drilling rig platform is rotatably connected to the crawler chassis through a slewing support, and the rotation angle of the drilling rig platform is adjusted by the slewing support; the crawler chassis of the self-propelled anchor drilling rig is different from the crawler chassis of the excavator. In order to reduce the production cost, the crawler chassis used by the self-propelled anchor drilling rig is mostly a simple structure, and the driving wheel of this crawler chassis is connected to the motor or hydraulic The output shaft of the hydraulic motor is directly connected; the output shaft of the motor or hydraulic motor is subjected to a large bending moment during the construction process; in order to protect the crawler chassis and keep the drilling rig platform stable, hydraulic legs are usually provided at the four corners of the drilling rig platform, but most of the ground on the construction site is not flat enough, and it is difficult to make the four hydraulic legs touch the ground at the same time or control the four hydraulic legs to touch the ground just right. In the process of lifting the drilling rig platform, the crawler chassis is easily subjected to force on one side, so that the output shaft of the motor or hydraulic motor on the force side is subjected to a larger bending moment; in addition, the existing drilling rig platform is difficult to adjust to a horizontal state, so that the hydraulic legs are always subjected to a large bending moment and are easily damaged. The above defects are problems that technical personnel in this field need to solve urgently;

[0003] A Chinese patent (publication number: CN220888685U) discloses a slope anchoring drill rig that is easy to move; the patent includes a support plate, and a moving mechanism is arranged on both sides of the support plate; a transmission block is arranged at the top of the support plate, and the top of the transmission block is rotated to connect with a connecting plate, and the top of the connecting plate is provided with an anchoring drill rig body, and the inner surface of the connecting plate is fixedly connected with a hydraulic rod, and one end of the hydraulic rod is fixedly connected with a supporting foot, and the hydraulic rod drives the supporting foot to move through a cylinder and a telescopic rod, so that the bottom end of the supporting foot contacts the ground, thereby fixing the anchoring drill rig body, so as to facilitate its work; but in actual use, it is found that due to the uneven ground at the construction site, it is difficult for the supporting feet to land at the same time. In the process of supporting the connecting plate, the moving mechanisms on both sides of the support plate will be subjected to a large lateral force, which is easy to cause the transmission shaft and the hydraulic rod of the moving mechanism to bear a large bending moment, resulting in greater difficulty in the extension operation of the hydraulic rod.
