Description

Technical Field

[0001] The utility model relates to the technical field of raise boring machines, in particular to a raise boring machine righting device. Background Art

[0002] The raise boring rig uses the drilling rig's motor to drive the hydraulic motor, which drives the faucet and uses hydraulic power to transmit torque to the drilling tool system, driving the drill rod and drill bit to rotate. Under the action of the bit pressure, the roller cutter on the pilot drill bit or reaming drill bit rolls or slides slightly along the rock working surface at the bottom of the well. At the same time, the axial tension and pressure generated by the main oil cylinder also act on the pilot drill bit or the reaming drill bit through the power head and the drill pipe, causing the roller cutter of the pilot drill bit to roll under the action of the bit pressure, generating an impact load, causing the roller cutter teeth to impact, squeeze and shear the rock, breaking the rock. After the drill pipe is installed, the drill pipe needs to be straightened. When the existing straightening device is in use, two symmetrical driving cylinders are generally used to directly push the straightening block to straighten the drill pipe. However, when the drill pipe is subjected to a transverse force, it is easy to react on the driving cylinder, causing a transverse force to the driving cylinder as well, which is easy to damage the driving cylinder and thus easy to cause the drill pipe to become loose. For this reason, a raise boring rig straightening device with a double safety locking function is designed to avoid the situation where the driving cylinder is used alone and is prone to loosening when there is a transverse force, thereby improving the straightening stability. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In response to the deficiencies in the prior art, the utility model provides a raise boring rig straightening device with a double safety locking function, which avoids the situation in which the straightening may become loose when a driving cylinder is used alone and improves the straightening stability.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a raise boring rig straightening device, comprising a fixed frame, wherein two U-shaped straightening plates are symmetrically and slidably fitted in the middle of the fixed frame, and driving cylinders for driving the U-shaped straightening plates on the same side to feed toward the middle are respectively provided on both sides of the two U-shaped straightening plates, and the driving cylinders and the U-shaped straightening plates on the same side are connected by a buffer transition mechanism, and the two U-shaped straightening plates are provided with pulling and locking mechanisms on both sides of the middle position of the two U-shaped straightening plates to move the two U-shaped straightening plates toward the middle.

[0007] Preferably, the pulling and locking mechanism includes a bidirectional screw rotatably connected to the fixed frame, and the two U-shaped straightening plates can be symmetrically threadedly connected to the bidirectional screw, and also includes a driving component for driving the bidirectional screw to rotate.

[0008] Preferably, the driving component drives the middle position of the bidirectional screw. The driving component includes a centering motor fixedly installed on the fixed frame. The output shaft of the centering motor is fixedly installed with a driving bevel gear. The middle position of the bidirectional screw is fixedly installed with a transmission bevel gear meshing with the driving bevel gear. Embedded grooves are symmetrically formed on both of the two U-shaped centering plates.

[0009] Preferably, the buffer transition mechanism includes a buffer frame fixedly connected to the U-shaped centering plate. A sliding plate is slidably fitted on one side of the buffer frame away from the U-shaped centering plate. An inner sliding seat and an outer sliding seat are respectively fixedly installed at both ends of the sliding plate. The output shaft of the driving cylinder is fixedly connected to the outer sliding seat.

[0010] Preferably, guide sliders are fixedly installed on both sides of the buffer frame and are slidably guided and fitted with the fixed frame. Guide rods are fixedly installed on both sides of the bidirectional screw and are slidably guided and fitted with the guide sliders.

[0011] Preferably, fixing blocks for the bidirectional screw to rotate are respectively arranged on both sides of the driving bevel gear and the transmission bevel gear. Both of the two fixing blocks are fixedly connected to the fixed frame and can be hidden in the embedded grooves.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides an alignment device for a raise boring machine, which has the following beneficial effects:

[0014] For this alignment device of the raise boring machine, two driving cylinders are convenient to drive the two U-shaped centering plates to move towards the middle. When moving to contact the pulling and locking mechanism, the two U-shaped centering plates can be further driven by the pulling and locking mechanism to continue to be centered and lock the rotating rod. While the pulling and locking mechanism is pulling, through the setting of the buffer transition mechanism, the driving cylinder is not affected by the pulling of the pulling and locking mechanism. When the pulling and locking mechanism locks the drill rod with the two U-shaped centering plates, the driving cylinders on both sides can continue to push to give a thrust to the U-shaped centering plates, so that the U-shaped centering plates are locked by the two structures of the driving cylinder and the pulling and locking mechanism. While improving the locking stability, it also avoids the situation that the alignment is easily loosened when using a single driving cylinder and there is a transverse cutting force. The pulling and locking mechanism can also lock the U-shaped centering plates alone. This alignment device of the raise boring machine has a double-insurance locking function, avoiding the situation that the alignment is easily loosened when using a single driving cylinder and there is a transverse cutting force, and improving the alignment stability.

[0023] Embodiment:

A buffer transition mechanism is connected between the driving cylinder 2 and the U-shaped straightening plate 3 on the same side. On both sides of the middle positions of the two U-shaped straightening plates 3, a pulling and locking mechanism for moving the two U-shaped straightening plates 3 towards the middle is arranged. During use, the fixed frame 1 is first fixedly installed on the raise boring machine.

[0025] Specifically, the pulling and locking mechanism includes a bidirectional screw 9 rotatably connected to the fixed frame 1. The two U-shaped straightening plates 3 are symmetrically threadedly connected to the bidirectional screw 9. It also includes a driving component for driving the bidirectional screw 9 to rotate. Through the driving component, it is convenient to drive the bidirectional screw 9 to rotate clockwise or counterclockwise, so as to drive the two U-shaped straightening plates 3 to move towards the middle or towards both sides.

A driving bevel gear 12 is fixedly installed on the output shaft of the centering motor 14. A transmission bevel gear 13 meshing with the driving bevel gear 12 is fixedly installed at the middle position of the bidirectional screw 9. Embedded grooves 10 are symmetrically formed on both of the two U-shaped centering plates 3. Through the arrangement of the embedded grooves 10, when the two U-shaped centering plates 3 are closed, it is convenient to hide the driving bevel gear 12 and the transmission bevel gear 13 and ensure the locking of the two U-shaped centering plates 3.

[0027] Specifically, the buffer transition mechanism includes a buffer frame 4 fixedly connected to the U-shaped centering plate 3.

[0028] Specifically, guide sliders 8 fixedly installed on both sides of the buffer frame 4 are slidably and guidingly fitted with the fixed frame 1. Guide rods 15 slidably and guidingly fitted with the guide sliders 8 are respectively fixedly installed on both sides of the bidirectional screw 9. Through the cooperation of the guide sliders 8, the fixed frame 1 and 19, the horizontal movement stability of the buffer transition mechanism and the U-shaped centering plate 3 is improved. At the same time, it is convenient to connect the U-shaped centering plate 3 to the bidirectional screw 9.

[0029] Specifically, fixing blocks 11 for the rotation of the bidirectional screw 9 are respectively arranged on both sides of the driving bevel gear 12 and the transmission bevel gear 13. Both of the two fixing blocks 11 are fixedly connected to the fixed frame 1 and can be hidden in the embedded grooves 10. Through the arrangement of the fixing blocks 11, it is convenient to support the bidirectional screw 9 and limit the two U-shaped centering plates 3 at the same time, avoiding the situation of excessive locking force.
