Compared with the prior art, the utility model has the advantages that: the drill frame of the utility model is folded twice to achieve the purpose of convenient transportation and storage while requiring a height; the utility model has a simple structure, and each drill frame is connected The structure is compact and the fixing effect is good. The drilling frame is raised or retracted by the folding oil cylinder. The third drilling frame is completely folded on the side of the second drilling frame. When opening, it can be opened by turning it manually. It is easy to operate and has high practicability.

As an improvement, the pulley mechanism includes a bottom plate connected to the third drilling frame, two side plates connected to the bottom plate, and pulleys located between the two side plates, and a set for the wire rope is installed between the two side plates. Limiting function Rotatable limit sleeve, the pulley mechanism of this structure is convenient to connect with the third drill frame, the setting of the limit sleeve has a limit effect on the wire rope, the limit sleeve is set as a rotatable structure, when the steel wire rope is in the limit When the position sleeve is put on, the friction force between the steel wire rope and the limit sleeve can be reduced, so that the limit sleeve can limit the position of the steel wire rope without affecting the normal working state and service life of the steel wire rope.

As an improvement, the detachable connection between the pulley mechanism and the third drilling frame is through bolt connection, and the bolt connection has a good fixing effect and is convenient for installation and disassembly.

As an improvement, the hinge between the third drilling frame and the second drilling frame is provided with a connecting plate and bolts that fix the third drilling frame and the second drilling frame, when the third drilling frame and the second drilling frame are in the When in the vertical state, the two drilling frames are fixed by the connecting plate of the bolts, which can prevent the third drilling frame from tilting.

As an improvement, the length of the third drilling frame is less than the length of the second drilling frame, this structure is convenient to fold the third drilling frame to the second drilling frame, and the third drilling frame will not exceed the length of the second drilling frame , occupying additional space without increasing the overall volume of the device.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to the accompanying drawings, a foldable drill frame includes a drill body 1, a first drill frame 2 vertically arranged on the drill body 1, a second drill frame 3 hinged to the end of the first drill frame 2 and a The third drilling frame 4 with the hinged ends of the second drilling frame 3, the first drilling frame 2 and the second drilling frame 3 are provided with a connecting plate 5 with one end hinged and corresponding to each other, the drilling machine body 1 and the second drilling frame 3 A folding oil cylinder 6 that can drive the second drilling frame 3 to rotate is arranged between the two drilling frames 3. The number of the third drilling frame 4 is two symmetrically arranged at both ends of the second drilling frame 3, and one side is the second The end of the three drilling frames 4 is provided with a pulley mechanism 7, which matches with the end of the third drilling frame 4 on the other side and is detachably connected.
