Embodiment 1
[0031] Such as figure 1 As shown, the mast folding front lying transport structure of the high-torque rotary drilling rig in this embodiment includes a main engine assembly 1, a front lying luffing mechanism 2, and a segmented mast. The segmented mast includes a lower mast 3 , a middle mast 4 , and an upper mast 13 , and a front lying luffing mechanism 2 is installed between the main engine assembly 1 and the lower mast 3 . The mast is installed at the front end of the main engine assembly. When it needs to be transported, the front lying luffing mechanism assembly 2 moves to make the segmented mast rotate from an upright state to a horizontal state, so as to reduce the weight of the whole machine as much as possible during transportation. Length and height, first disassemble the upper mast 13, that is, the mast in the transport state only includes the middle mast 4 and the lower mast 3. The lower mast 3 and the middle mast 4 are hinged by a rotating seat, which can be folded...

A front bending type transporting structure for folding masts of a high-torque rotary drilling rig comprises a main machine assembly (1), a front bending luffing mechanism (2), and masts. The masts comprise a middle mast (4) and a lower mast (3), wherein the middle mast is connected with the lower mast in a hinged mode. The front bending luffing mechanism is arranged on the main machine assembly. The upper portion of the lower mast is hinged to the front bending luffing mechanism through a mast oil cylinder (5). The lower portion of the lower mast is hinged to the front bending luffing mechanism. In the transporting state, the front bending luffing mechanism matched with of the mast oil cylinder (5) to gradually move from the back leaning position to the front bending position, so that the masts gradually are transferred from the vertical position to the general horizontal slightly front bending position, and located below an in front of a navigation room of the main machine assembly. The middle mast (4) and the lower mast (3) are folded in the side direction. According to the front bending type transporting structure for folding the masts of the high-torque rotary drilling rig, the transportation length of the high-torque rotary drilling rig is shortened. Meanwhile, by means of the front bending structure, the transportation height is greatly lowered.
Description
technical field [0001] The utility model relates to the technical field of pile construction machinery, in particular to a mast folding front lying transport structure of a high-torque rotary drilling rig. Background technique [0002] Rotary drilling rigs have a self-lifting folding mast. In recent years, the domestic rotary drilling rig market has developed steadily, and the series and models of rotary drilling rigs have become more and more complete. The torque is concentrated between 4t.m and 55t.m, such as Figure 7 As shown, as far as the mainstream market is concerned, the mast support of rotary drilling rigs with a torque below 32t. The left and right mast oil cylinders 03, the tetrahedron formed by connecting the mast and the turntable 06 with pins; 2. The parallelogram is formed by connecting the platform 01, the boom 02, one side of the triangle connector 05 and the strut 07 with pins; 3 . Since the two holes of the main engine platform and the main engine work t...
