[0040] The forklift 1 can refer to the existing forklift, such as the XJ988-35 forklift, which includes a frame 11, a cab 12 mounted on the frame 11, a wheel 13 mounted under the frame 11, and a travel drive mechanism mounted on the frame 11 and capable of transmitting and connecting the wheel 13 to drive the wheel 13 to rotate, and the wheel 13 is driven to rotate by the travel drive mechanism to drive the forklift 1 to travel. The forklift 1 is also equipped with a hydraulic mechanism. The fork 21 can be movably connected to the forklift 1, and a fork drive mechanism is provided between the fork 21 and the forklift 1. The fork drive mechanism drives the fork to move relative to the forklift, and the movement includes lifting or angular rotation. The fork drive mechanism includes a lifting arm 14 and a second cylinder mechanism 15.

[0041] The hydraulic mechanism of the forklift 1 connects the first cylinder mechanism, the second cylinder mechanism and the third cylinder mechanism to control the movement of the push-pull frame, the lifting and lowering of the fork, and the adjustment of the angle of the fork. The hydraulic mechanism is, for example, a hydraulic source controlled by a multi-way valve.

[0042] Hole extraction methods for forklifts include:

[0043] Step 1: The fork driving mechanism drives the fork 21 to move so that the fork joint 211 of the fork 21 corresponds to the lower edge of the hole 3, for example, the fork joint 211 is horizontally aligned with the lower edge of the hole 3, or is slightly lower than the lower edge of the hole 3;

[0044] Step 2: The first piston rod 233 of the first oil cylinder mechanism extends, driving the scissor mechanism 231 to extend horizontally (the push-pull frame moves away from the connecting frame 213), and pushing the push-pull frame 22 outward to move the push-pull frame 22 outward;

[0045] Step 3, please refer to Figure 3 , the hole-mined object 3 and the push-pull frame 22 are connected together by the steel rope 222; the specific structure is, for example: grooves are processed on both sides of the hole-mined object 3, and the ends of the steel rope 222 are connected to the grooves. If a pin is fixedly inserted in the groove, the steel rope 222 is connected to the pin, and the hole-mined object 3 and the push-pull frame 22 are connected together; or, the steel rope 222 and the push-pull frame 22 cooperate to form a rope ring, and the rope ring is sleeved on the hole-mined object 3, so that the hole-mined object 3 and the push-pull frame 22 are connected together;

[0046] Step 4: The first piston rod 233 of the first oil cylinder mechanism is retracted, driving the scissor mechanism 231 to shorten horizontally (the push-pull frame approaches the connecting frame 213), and the push-pull frame 22 is pulled inward to move the push-pull frame 22 inward, so as to pull the hole-picked object 3 onto the fork connection portion 211 of the fork 21, as shown in FIG. Figure 4 As shown; as needed, the hole-picked objects can be moved to the fork joint 211 of the fork 21 in coordination with the movement of the fork, such as being pulled to the fork joint 211 by a push-pull frame, and then the fork is moved so that the hole-picked objects are completely moved to the fork joint 211.

[0047] Step 5, please refer to Figure 4 The forklift 1 can directly transport the mined object 3 to the destination (stack site or transportation vehicle, etc.), or the forklift 1 can drive the fork 21 to move so that the mined object 3 is safely placed on the fork 21 and then transported to the destination;

[0048] Step 6, please refer to Figure 5 The fork connection portion 211 of the fork 21 corresponds to the upper edge of the target platform at the destination; the first piston rod 233 of the first cylinder mechanism extends, driving the scissor mechanism 231 to extend horizontally (the push-pull frame moves away from the connecting frame 213), and the push-pull frame 22 pushes the mined object 3 to the target platform.

[0049] Before step 3, Figure 3 As shown, the method further includes step A, wherein a plurality of cylindrical parts 4 are provided under the hole-mined object 3, such as plugs in the cutting seam 31, so as to convert the sliding friction into rolling friction during the process of pulling out the hole-mined object 3, thereby reducing the friction of the hole-mined object and reducing wear. The cylindrical parts are round steels of φ16-φ20. The step A can be before step 1, or between step 1 and step 2, or between step 2 and step 3. Between step 4 and step 6, the method further includes step B: untying the connection between the steel rope and the hole-mined object 3.

[0050] In another embodiment: Figure 6 , Figure 7 and Figure 8 As shown, before step 3, step A is also included, wherein a slide plate 5 is inserted under the hole-mined object 3, such as a slide plate 5 is inserted in the cutting seam 31. The slide plate 5 includes a plate body, and the top surface of the plate body is provided with a smooth area and a raised area arranged front and back; the raised area is evenly spaced along the front and back directions. A number of anti-slip protrusions 51 are arranged; and the smooth area is provided with a number of connecting holes 52. In the specific structure: the anti-slip protrusion 51 has a front side wall 511 and a rear side wall 512 arranged front and back, the front side wall 511 is a concave wall with an opening facing forward, and the rear side wall 512 is an inclined wall arranged forward and upward; or, the front side wall 511 is a front inclined wall, and an acute angle with an opening facing forward is formed between the front inclined wall and the bottom wall, and the rear side wall 512 is an inclined wall arranged forward and upward to prevent the hole-mined object from sliding backward during the pushing and pulling process; the slide plate uses material 50Mn2.

[0051] In the step A, first partially insert the slide plate 5 into the cutting slit 31, or align the cutting slit 31, and then directly use the fork 21, or the push-pull frame 22 to push the slide plate 5 into the cutting slit 31. Specifically, step A is before step 1, or between step 1 and step 2, first partially insert the slide plate 5 into the cutting slit 31, or align the cutting slit 31; and in step 2, the push-pull frame 22 pushes against the front end of the slide plate, and the push-pull frame 22 moves outward to insert the lower edge of the hole-collected object into the slide plate from front to back. In step 3, the steel rope 222 is connected to the connecting hole 52 of the slide plate 5, so as to connect the hole-collected object and the push-pull frame together through the slide plate and the steel rope.

[0052] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
