Technical Field

[0001] The utility model relates to the field of drilling rig rotation, in particular to an automatic rotating mechanism for a drilling rig. Background Art

[0002] The automatic rotation mechanism of the drilling rig is an important component of the drilling rig. It is responsible for driving the drill bit to perform rotary drilling. The automatic rotation mechanism of the drilling rig can realize continuous rotary drilling of the drill bit, greatly improving the drilling efficiency. It has the characteristics of high efficiency, accuracy, high degree of automation and strong adaptability.

[0003] The automatic rotation mechanism of the drilling rig can efficiently transmit power to the drill rod through a precise transmission system and power source, achieving fast and stable rotational movement. The automatic rotation mechanism of the drilling rig has significant advantages in improving drilling efficiency, stability and reliability.

[0004] The existing drilling rig and the rotating mechanism are usually connected by a thread. It is found in use and observation that the installation process of this connection method is relatively complicated and it is not convenient for replacing and repairing the drilling rig.

[0005] Therefore, in response to the above problems, a drilling rig automatic rotation mechanism is proposed. Utility Model Content

[0007] The technical solution adopted by the utility model to solve its technical problems is: the automatic rotation mechanism of a drilling rig described in the utility model is characterized in that: it includes a rotary machine; a placement groove is provided at the bottom of the rotary machine; a slide groove is provided on the outer side wall of the rotary machine; a group of sliders are slidably connected in the slide groove; a limiting groove is provided on the outer side wall of the rotary machine; a plurality of pull ropes are fixedly connected to the inner side wall of the slider; a limiting plate is fixedly connected to the inside of the limiting groove; a plurality of limiting holes are provided on the limiting plate; a first spring is fixedly connected to the side wall of the limiting plate; the end of the first spring is fixedly connected to the limiting block; the limiting block and The pull ropes are all fixedly connected; the limit block and the limit groove are slidably connected; a drilling rig is installed inside the placement groove; a card slot is provided on the drilling rig; during normal operation, the first spring is in a compressed state, and a slider is connected by sliding in the slide groove. When a group of sliders move along the slide groove, it drives the pull rope fixed to the inner wall of the slider to move, and the pull rope drives the limit block fixed at its end to move together, which can achieve the fixation of the drill bit. When the slider is slid at the same time, the limit block is pulled out to release the fixation of the drill bit, reducing the working time required for the device to disassemble and replace the drill bit, and improving the convenience of drill bit maintenance and replacement.

[0008] Preferably, a magnet group is fixedly connected between the group of sliders; the magnet groups are correspondingly arranged, and when the slider slides along the slide groove, the distance between the pair of magnet groups will change. At this time, the sliders will approach each other under the magnetic attraction of the magnet group itself, so that one slider will move toward the other slider, reducing the resistance of the slider due to its own gravity when moving. By fixing the magnet group between a group of sliders, the device can be affected by the magnetic force of the magnet group when adjusting the slider, reducing the resistance of the slider due to its own gravity when sliding, and improving the convenience of slider adjustment.

[0009] Preferably, a plurality of rollers are rotatably connected to the interior of the limiting groove; the rollers are arranged in an array. When the slider slides along the slide groove, the pull rope fixed to the inner side wall of the slider also moves. At this time, the pull rope moves on the surface of the rollers. By fixing the rollers inside the limiting groove, the friction between the pull rope and the side wall of the limiting groove can be reduced during the pull rope movement, thereby reducing the wear of the pull rope and extending the service life of the pull rope.

[0010] Preferably, a plurality of second springs are fixed to the inner side wall of the placement slot; an elastic cloth is fixed to the end of the second spring; the elastic cloth is located between the drill bit and the placement slot.

[0011] Preferably, a plurality of third springs are fixed to the top of the inner wall of the placement groove; a rubber block is fixed to the end of the third spring; by fixing a plurality of third springs to the top of the inner wall of the placement groove and a rubber block to the end of the third spring, the elastic cloth can be compressed during rotation to achieve auxiliary fixation of the drill bit.

[0012] Preferably, a dustproof plate is fixedly connected to the bottom of the rotary machine; the drilling rig is located inside the dustproof plate. By fixing the dustproof plate to the outside of the drilling rig, it is possible to reduce the damage to the drill bit caused by impurities entering the drill bit and the placement slot during operation.

[0013] The utility model is beneficial in that:

[0014] 1. A slider is connected by sliding in the slide groove. When a group of sliders moves along the slide groove, it drives the pull rope fixed to the inner wall of the slider to move. The pull rope drives the limit block fixed to its end to move together, which can fix the drill bit. When the sliders are slid at the same time, the limit block is pulled out to release the fixation of the drill bit, reducing the working time required for disassembly and replacement of the drill bit and improving the convenience of drill bit maintenance and replacement.

[0015] 2. By fixing a magnet group between a group of sliders, the device can adjust the sliders by the magnetic force of the magnet group, thereby reducing the resistance of the sliders due to their own gravity when sliding, and improving the convenience of slider adjustment.

Under the action of the first spring 18 and the limit hole 17, the limit block 19 moves to the specified position and stops. When the drill bit 110 is placed at the specified position, the slider 13 connected to the sliding groove 12 moves to drive the pull rope 15 to move. At the same time as the pull rope 15 moves, the limit block 19 moves accordingly under the action of the first spring 18. When the limit block 19 moves to the specified position, the limit block 19 engages with the slot 111 The drill bit 110 is fixed together by sliding a slider 13 in the slide groove 12. When a group of sliders 13 move along the slide groove 12, it drives the pull rope 15 fixed to the inner wall of the slider 13 to move. The pull rope 15 drives the limit block 19 fixed to its end to move together, which can fix the drilling rig. When the slider 13 is slid at the same time, the limit block 19 is pulled out to release the fixation of the drill bit 110, reducing the working time required for the device to disassemble and replace the drill bit 110, and improving the convenience of repairing and replacing the drill bit 110.
