The embodiment of the utility model provides an automatic device that unloads of ZLJ type rig drilling rod, as shown in figure 1 and figure 2, include: the device comprises an upper hydraulic clamping mechanism 1, a lower hydraulic clamping mechanism 2, a reverse fixed guide pillar 3 and a drilling machine body 4; the drilling machine body 4 is provided with a drill rod connecting port, drill rods are telescopically connected in the drill rod connecting port, and two adjacent drill rods 5 are connected end to end through drill rod connectors 6; the lower hydraulic clamping mechanism 2 is fixedly connected to the upper side of the drilling machine body 4, and the lower hydraulic clamping mechanism 2 is provided with a lower clamping opening; the reverse fixed guide pillar 3 is arranged parallel to the drill rod 5, and the lower end of the reverse fixed guide pillar 3 is fixedly connected with the drilling machine body 4, optionally, a connecting chassis 42 is arranged on the upper side of the drilling machine body 4, and the lower end of the reverse fixed guide pillar 3 is fixedly connected on the connecting chassis 42; the upper hydraulic clamping mechanism 1 is connected to the reverse fixed guide post 3 in a vertically sliding manner, the upper hydraulic clamping mechanism 1 is provided with an upper clamping port, and the lower clamping port, the upper clamping port and the drill rod connecting port are located on the same straight line, so that the straight line is the straight line where the drill rod 5 is located. The utility model discloses it will treat two drilling rods 5 of dismantlement tightly to utilize last hydraulic clamping mechanism 1 and lower hydraulic clamping mechanism 2, then utilizes the rotation of rig itself to dismantle two drilling rods 5 and come, realizes the function that 5 automatic pine of drilling rod unloaded. In a specific embodiment, in order to ensure that the two drill rods 5 are smoothly detached, the drill rig drives the drill rods 5 to rotate in the forward direction, and the connecting threads between the drill rods 5 and the drill rod connectors 6 are both positive threads. Therefore, the disassembly steering between the drill rod 5 and the drill rod connector 6 is consistent with the steering of the drilling machine, and the disassembly action of the drill rod 5 can be completed by directly utilizing the power of the drilling machine.
The lower side of the drilling machine body 4 is connected with a lifting oil cylinder 41, the upper side of the drilling machine body 4 is connected with a connecting chassis 42, an output shaft of the lifting oil cylinder 41 penetrates through the drilling machine body 4 to be in driving connection with the connecting chassis 42, and the lower hydraulic clamping mechanism 2 and the reverse fixing guide pillar 3 are both fixedly connected to the connecting chassis 42. The lower hydraulic clamping mechanism 2 also has the function of driving the drill rod 5 to rotate on the drilling machine body 4. In addition, after the lower hydraulic clamping mechanism 2 clamps the drill rod 5, the lifting oil cylinder 41 drives the lower hydraulic clamping mechanism 2 to move up and down, so that the drill rod 5 is pulled out or drilled in.
In one aspect of the embodiment of the present invention, the middle part of the reverse fixing guide pillar 3 has a lower stopper 31, and the upper hydraulic clamping mechanism 1 is located above the lower stopper 31. The lower limiting member 31 serves to limit the upper hydraulic clamping mechanism 1, and keeps enough space between the upper hydraulic clamping mechanism 1 and the drilling machine body 4 for accommodating the drill rod connector 6 between the two drill rods 5, so as to ensure that the disassembly is smoothly performed.
Preferably, the top of the reverse stationary guide post 3 has an upper stopper 32, and the distance between the upper surface of the upper hydraulic clamping mechanism 1 and the upper stopper 32 is greater than the length of the connection thread part of the drill rod coupling head 6. The upper limiting piece 32 is arranged to limit the upper part of the upper hydraulic clamping mechanism 1, so that the upper hydraulic clamping mechanism 1 is prevented from sliding out of the upper end of the reverse fixed guide pillar 3, and the reverse fixed guide pillar 3 is adapted to a working scene with a certain inclination angle. Meanwhile, since the connection thread between the drill rod connector 6 and the drill rod 5 is unscrewed during the actual disassembly process, the upper hydraulic clamping mechanism 1 is jacked up, and in order to avoid the jacked upper hydraulic clamping mechanism 1 from generating extrusion collision with the upper limiting piece 32, the distance between the upper surface of the upper hydraulic clamping mechanism 1 and the upper limiting piece 32 is set to be greater than the length of the connection thread part of the drill rod connector 6.
Preferably, a return spring 33 is sleeved on the reverse fixing guide post 3 between the upper hydraulic clamping mechanism 1 and the upper limiting member 32 and the lower limiting member 31. The return spring 33 applies elasticity to the upper hydraulic clamping mechanism 1, so that the upper hydraulic clamping mechanism is returned to the middle position as soon as possible after being used, and the return effect is achieved; in addition, the return spring 33 can also play a role of buffering, so as to avoid collision between the upper hydraulic clamping mechanism 1 and the lower limiting member 31.

The design of the two reverse fixing guide columns 3 is beneficial to the smooth installation and operation of the upper hydraulic clamping mechanism 1 on the reverse fixing guide columns 3. It will be appreciated that the reverse stationary guide posts 3 may be more, to achieve a more smooth mounting of the lower hydraulic clamping mechanism 2. Alternatively, the lower end of the reverse stationary guide post 3 may be mounted on the side of the drilling machine body 4 or other positions where the reverse stationary guide post 3 can be fixedly mounted.
In an aspect of the embodiment of the present invention, as shown in fig. 3, the upper and lower surfaces of the upper hydraulic clamping mechanism 1 are both provided with a sliding plate 11, the sliding plate 11 is provided with a reverse fixing guide pillar coupling hole 111 and a drill rod coupling hole 112, the reverse fixing guide pillar 3 passes through the reverse fixing guide pillar coupling hole 111, and the drill rod 5 passes through the drill rod coupling hole 112. The design facilitates the assembly of the upper hydraulic clamping mechanism 1, the reverse fixed guide post 3 and the drill rod 5, and is favorable for guaranteeing the running stability of the upper hydraulic clamping mechanism 1.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
