Description

Technical Field

[0001] The utility model relates to the technical field of drilling rig outriggers, in particular to an outrigger capable of self-adapting to ground angles. Background Art

[0002] Due to the limited space and flat ground at the construction site of small drilling rigs, the drilling rig's entry angle is required to have a very high range, so the outrigger support angle range is required to be large and the structural strength is high.

[0003] Therefore, a kind of outrigger with adaptive ground angle is proposed. If the ground at the construction site is not horizontal and has an angle, the fixed pin shaft is removed and the outrigger base plate will automatically adjust according to the actual angle of the ground to ensure that the whole machine is supported and maintains a stable and balanced state. During transportation, the outrigger needs to be folded up and the fixed base plate pin shaft is reinstalled to ensure that the departure angle of the machine transportation meets the requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a support leg that is adaptive to the ground angle, including a drilling rig body, a mounting bracket is provided at the front center position of the drilling rig body, the upper part of the mounting bracket is connected to one end of the support leg cylinder through a pin shaft 1, the lower part of the mounting bracket is connected to one end of the support leg arm through a pin shaft 2, the other end of the support leg cylinder is connected to the upper rear end of the support leg floating base plate through a pin shaft 3, and the other end of the support leg arm is connected to the support leg floating base plate through a pin shaft 4.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0006] The utility model provides an outrigger oil cylinder, and connects the two ends of the outrigger oil cylinder to the mounting frame and the outrigger floating base plate through a pin shaft 1 and a pin shaft 3 respectively. The extension and contraction of the outrigger oil cylinder can make the crawler on the drilling rig body move away from the ground or close to the ground, and the outrigger floating base plate can adjust itself according to the ground angle, so as to meet the requirements of the burial angle.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] As attached Figure 1-3 As shown, the utility model provides a support leg with adaptive ground angle, including a drilling rig body 1, a mounting frame 2 is provided at the front center position of the drilling rig body 1, the upper part of the mounting frame 2 is connected to one end of the support leg cylinder 4 through a pin 1 3, the lower part of the mounting frame 2 is connected to one end of the support leg arm 5 through a pin 2 6, the other end of the support leg cylinder 4 is connected to the upper rear end of the support leg floating base plate 8 through a pin 3 7, and the other end of the support leg arm 5 is connected to the support leg floating base plate 8 through a pin 4 9.

[0014] Specifically, an oil cup 10 is provided on the pin shaft 9 above the supporting leg floating bottom plate 8.

[0015] Specifically, a pin shaft 5 11 is further provided on the support leg floating base plate 8 .

[0016] Working principle: If the construction site has a large space, during operation, you only need to support the outrigger arm 2 on the ground, the crawler on the drilling rig body 1 is in contact with the ground, and the outrigger floating base plate 8 will adjust to the appropriate angle according to the ground conditions to meet the required penetration angle;

[0017] If the construction site space is limited and a larger penetration angle is required, the outrigger cylinder 4 is fully extended to drive the outrigger floating base plate 8 downward. At this time, the crawler tracks on the drilling rig body 1 are off the ground, and the outrigger floating base plate 8 will be adjusted to a suitable angle according to the ground conditions to meet the penetration angle requirement;

[0018] During transportation, the outrigger oil cylinder 4 retracts, driving the outrigger floating base plate 8 to lift up, and then the outrigger arm 2 lifts up, and the outrigger floating base plate 8 is fixed by the pin shaft 5 11 to ensure that the machine transportation departure angle meets the requirements.
