Problems solved by technology
[0004] However, during the manufacturing process of the existing crawler-type rotary drilling rig, the left and right crawler frames installed on both sides of the vehicle support are fixed in a fixed way, so it cannot realize the adjustment of the center of gravity during the work process. Once the center of gravity is unstable or encounters special road conditions, it is impossible to change the relative position between the left and right crawlers in time to adjust the center of gravity of the whole machine. At the same time, it also increases the labor intensity and work risk factor of the operators

Embodiment Construction
[0013] The quadrilateral crawler luffing mechanism of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] The quadrilateral track luffing mechanism of the present invention can change the center of gravity of the excavator by changing the relative position of the track, refer to figure 1 and figure 2 Shown in, comprise vehicle frame 10, left crawler frame 11, right crawler frame 12 and movable connecting rod 13.
[0015] In the present invention, the number of the movable connecting rods 13 is 4, every two movable connecting rods 13 are a group, and the movable connecting rods 13 are all movably connected, and one group connects the left crawler frame 11 and the vehicle frame 10 together. The other group connects the right crawler frame 12 with the other side of the frame to form a movable quadrilateral connection relationship between the frame 10 and the crawler frame.

The invention discloses a quadrilateral caterpillar track luffing mechanism which comprises a frame, a left caterpillar track frame, a right caterpillar track frame and a moveable connecting rod, wherein the left caterpillar track frame and the right caterpillar track frame are moveably arranged on two sides of the frame through the moveable connecting rod; the moveable connecting rod is moveably connected with the frame, the left caterpillar track frame and the right caterpillar track frame; and during an operation process, the relative positions of the left and right caterpillar track frames and the base of an excavator can be changed through the motion of the moveable connecting rod, so as to realize the adjustment on the center of gravity of the excavator. The quadrilateral caterpillar track luffing mechanism has the advantages that the center of gravity of the excavator can be adjusted according to practical requirements and the stability and the safety during the operation are high.
Description
technical field [0001] The invention relates to the field of construction machinery equipment, in particular to a luffing mechanism capable of adjusting the center of gravity. Background technique [0002] At present, in the field of construction engineering, the demand for drilling rigs and other equipment is becoming more and more extensive, especially crawler rotary drilling rigs, and for crawler rotary drilling rigs, the crawler walking device is an important part of its structure. The crawler walking device is mainly used to realize the driving function and support the weight of the whole machine. [0003] However, during the rotary excavation operation, due to the environmental factors of the construction site, the rotary excavation mechanism is often subjected to great resistance, which easily causes the center of gravity of the whole machine to be unstable. In order to make the rotary drilling rig more stable during operation, the current method is to adjust the cen...
