Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drilling engineering technology, specifically relating to a deep-hole core drilling device with anti-stuck-drill function. Background Technology
[0002] Deep-hole core drilling is a crucial step in geological exploration and mineral resource development. Its main purpose is to analyze underground geological structures, mineral composition, and reserve distribution by drilling core samples from deep underground strata. Deep-hole drilling typically requires complex geological conditions, including environments with high rock hardness, well-developed fractures, and abundant groundwater. Therefore, the performance of drilling equipment directly affects drilling efficiency, cost, and safety.
[0003] In existing technologies, when faced with complex geological conditions, such as hard rock layers, fault zones, and areas prone to borehole collapse, drilling operations often encounter the problem of drill bit jamming. Traditional drilling equipment often lacks effective protection mechanisms to deal with this situation. Once a drill bit jamming occurs, it can easily damage the drilling equipment and even threaten the safety of the operators. Utility Model Content

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0023] Example
[0024] Reference Figures 1-3 This embodiment of the present invention provides a deep-hole core drilling device with anti-stuck-drill function, comprising:
[0025] The bearing mechanism 100 includes a fixed column 101, a rack 102 fixedly installed on the outer surface of the fixed column 101, and a slider 103 slidably connected to the outer surface of the fixed column 101.
[0026] The drive mechanism 200 includes a traction rope 201, a traction post 202 fixedly installed on the outer end face of the traction rope 201, a spring piece 203 fixedly installed on the outer surface of the slider 103, and a locking component 204 for limiting the slider 103.
[0027] Specifically, the outer surface of the fixed column 101 slides in contact with the inner surface of the slider 103, and the outer surface of the traction column 202 slides in contact with the inner surface of the slider 103.
[0028] Furthermore, the traction post 202 passes through the spring piece 203, and the traction post 202 and the spring piece 203 are fixedly connected at the point of penetration.
[0029] Furthermore, the locking assembly 204 includes a guide rod 204a rotatably connected to the through-hole of the traction column 202, a fixing block 204b fixedly installed on the outer surface of the slider 103, and a limiting block 204c fixedly installed on the outer surface of the guide rod 204a and used in conjunction with the rack 102.
[0030] Preferably, a bearing sleeve for rotation is installed at the connection between the guide rod 204a and the traction column 202, and the inner surface of the fixing block 204b is rotatably connected to the outer surface of the guide rod 204a.
[0031] It should be noted that a bearing sleeve for rotation is installed at the connection between the fixing block 204b and the guide rod 204a, and the outer surface of the limiting block 204c meshes with the rack 102.
[0032] In use, by manipulating the traction rope 201, the traction column 202 can be pulled, causing the slider 103 to slide up and down along the fixed column 101. During this process, the traction column 202 applies pressure to the spring 203, causing the traction column 202 to drive the guide rod 204a to move. The guide rod 204a drives the limit block 204c to disengage from the rack, thereby releasing the lock. The slider 103 maintains sliding contact with the outer surface of the fixed column 101, while the traction column 202 also maintains sliding contact with the inner surface of the slider 103. When the slider 103 moves to the desired position, if the drill bit encounters an obstacle or gets stuck during drilling, the tension on the traction rope 201 will increase. At this time, the design of the spring 203 allows for a certain deformation to absorb the additional force, and the limit block 204c disengages from the rack 102, thereby automatically releasing the lock and protecting the entire device from damage.
[0033] In summary, the cooperation between the bearing mechanism 100 and the drive mechanism 200 can not only effectively prevent equipment damage caused by stuck drill bit, but also reduce the risk of personnel injury during operation, thus providing higher safety and reliability for deep hole core drilling operations.
