Description
Technical Field
[0001] This utility model relates to the field of drilling technology, specifically to an anti-hole deviation device for drilling rigs. Background Technology
[0002] A drilling rig is a complex machine consisting of components, units, and mechanisms. It is a mechanical device used in the exploration or development of mineral resources (including solid, liquid, and gaseous minerals) to drive drilling tools into the ground to obtain physical geological data. Also known as a drilling machine, its main function is to drive the drilling tools to break the rock at the bottom of the hole and to lower or lower the drilling tools into the hole. It can be used to drill cores, mineral cores, rock cuttings, gaseous samples, liquid samples, etc., to explore underground geology and mineral resources.
[0003] Drilling rigs are prone to tilting due to vibrations and impacts from hard materials. Also, since drilling rigs are usually used for exploration in the field, where there is no flat ground, the equipment lacks a leveling detection device, resulting in the equipment not being placed horizontally. This makes the drilling rig itself prone to tilting, which in turn indirectly causes the drill rod to tilt during drilling. The anti-tilting effect is not ideal. To address this, we propose an anti-hole tilting device for drilling rigs. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that drilling rigs are prone to tilting due to vibration of the drill bit and impact of hard materials, or that drilling rigs are generally used in the field for exploration without flat ground, resulting in the lack of a level detection device on the device during use, which makes the device not placed horizontally, causing the drilling rig itself to tilt, and indirectly causing the drill rod to tilt, resulting in an unsatisfactory anti-tilting effect. This utility model provides an anti-hole tilting device for drilling rigs.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] A drilling rig anti-hole deviation device includes a fixed vertical plate. A tilting crossbeam is fixedly connected to the upper end of the fixed vertical plate facing the drill rod, and a tilting correction arm is hinged to the side of the tilting crossbeam away from the fixed vertical plate. A contact groove wheel is hinged to the upper end of the tilting correction arm, and an elastic correction seat is fixedly connected to the center of the bottom of the fixed vertical plate facing the drill rod. A central slider is slidably connected to the center of the elastic correction seat, and mating convex shafts are fixedly connected to the centers of both sides of the central slider. The lower ends of both sides of the tilting correction arm are provided with grooved slides corresponding to the mating convex shafts, and the mating convex shafts are slidably connected in the grooved slides. A disc spring assembly is provided on the outer side of the grooved slide.
[0007] Furthermore, the inner cavity of the elastic correction seat is fixedly connected to the center of the central slider slide, and both the central slider and the disc spring assembly are movably sleeved on the guide central shaft.
[0008] Furthermore, an adjusting sleeve is movably connected to the outer side of the central slide of the elastic correction seat, and the inner end of the guide central shaft is movably inserted into the center of the adjusting sleeve. An adjusting screw is threadedly connected to the outer side of the fixed upright plate corresponding to the center of the adjusting sleeve, and the inner end of the adjusting screw and the outer end of the adjusting sleeve are rotatably connected through a bearing.
[0009] Furthermore, a connector is fixedly connected to the outer side of the adjusting screw, and an internal hexagonal slot is provided on the outer side of the connector.
[0010] Furthermore, a fixed base plate is fixedly connected to the bottom of the fixed plate on the side away from the drill rod, and multiple anchor bolt insertion holes are evenly opened on the fixed base plate.
[0011] Furthermore, a reinforcing diagonal brace is fixedly connected between the upper center of the fixed base plate and the upper outer side of the fixed upright plate.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model arranges multiple devices around the drill rod and fixes them in place with a fixed upright plate. The upper end of the tilting correction pressure arm contacts the grooved wheel tightly against the outer wall of the drill rod. The pressure between the grooved wheel and the outer wall of the drill rod is adjusted by the preload of the disc spring assembly. When the drill rod tilts due to vibration or impact from a hard object, the outer wall of the drill rod presses against the grooved wheel. The grooved wheel drives the tilting correction pressure arm to rotate around the hinge point. The tilting correction pressure arm, in conjunction with the cam shaft and the grooved slide, pushes the central slider to slide. At the same time, the central slider presses against the disc spring assembly. The rebound force of the disc spring assembly is used to correct the drill rod in the opposite direction, ensuring that the drill rod remains vertical and improving the drilling accuracy. Through the multiple sets of tilting correction pressure arms and elastic correction seats arranged in an array around the drill rod, combined with the elastic force of the disc spring assembly, effective correction of the drill rod is achieved, preventing the drill hole from tilting and improving the drilling accuracy and efficiency. With its simple structure, convenient operation, easy installation and maintenance, it greatly reduces the cost of use and improves economic efficiency. It has good adaptability and versatility and can be applied to drilling rigs of different models and specifications, meeting the needs of different users.
[0014] 2. This utility model adjusts the rotation of the adjusting screw to move the adjusting sleeve along the guide center axis, thereby adjusting the corrective force of the elastic correction seat on the drill rod. This design allows users to flexibly adjust the correction capability of the device according to the specific working environment of the drilling rig and the inclination of the drill rod, ensuring that the device maintains the best correction effect under different conditions.
[0015] 3. The fixed base plate design of this utility model ensures that the entire device is stably fixed to the ground, preventing shaking or displacement during use. The multiple anchor bolt holes allow users to select appropriate anchor bolt positions according to actual needs, further enhancing the stability and adaptability of the device. At the same time, the anchor bolt hole design also makes installation and disassembly of the device more convenient and quick, improving work efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0021] Please see Figures 1-3 This utility model provides an anti-hole deviation device for drilling rigs, including a fixed vertical plate 1. A flipping crossbeam 2 is fixedly connected to the upper end of the fixed vertical plate 1 facing the drill rod, and a flipping correction arm 3 is hinged to the side of the flipping crossbeam 2 away from the fixed vertical plate 1. A contact groove wheel 4 is hinged to the upper end of the flipping correction arm 3, and an elastic correction seat 5 is fixedly connected to the bottom center of the fixed vertical plate 1 facing the drill rod.

A disc spring assembly 10 is provided on the outer side of the grooved slides 8.
[0022] The working principle and usage process of this utility model are as follows: During installation, multiple devices are arranged around the drill rod and fixedly installed by a fixed upright plate 1. The upper end of the flip-correction pressure arm 3 contacts the grooved wheel 4 tightly against the outer wall of the drill rod. The pressure between the contact grooved wheel 4 and the outer wall of the drill rod is adjusted by the preload of the disc spring assembly 10. When the drill rod tilts due to vibration or impact from a hard object, the outer wall of the drill rod presses against the contact grooved wheel 4. The contact grooved wheel 4 drives the flip-correction pressure arm 3 to rotate around the hinge point. The flip-correction pressure arm 3 is pushed to slide on the central slider 6 by the cooperation of the convex shaft 7 and the grooved slide 8. At the same time, the central slider 6 presses against the disc spring assembly 10. The rebound force of the disc spring assembly 10 is used to correct the drill rod in the opposite direction, ensuring that the drill rod remains vertical and improving the drilling accuracy. Through the multiple sets of flip-correction pressure arms 3 and elastic correction seats 5 arranged around the drill rod array, combined with the elastic force of the disc spring assembly 10, the effective correction of the drill rod is achieved, preventing the drilling from tilting and improving the drilling accuracy and efficiency. With its simple structure, convenient operation, easy installation and maintenance, it greatly reduces the cost of use and improves economic efficiency. It has good adaptability and versatility and can be applied to drilling rigs of different models and specifications, meeting the needs of different users.

The guide center shaft 9 improves the stability of the sliding of the central slider 6 and ensures that the rebound force of the disc spring assembly 10 is evenly applied to the central slider 6, further improving the accuracy and effect of the correction. The guide center shaft 9 also supports and fixes the disc spring assembly 10, enhancing the stability and durability of the entire device.
[0024] In this embodiment, preferably, an adjusting sleeve 11 is movably connected to the outer side of the central slide of the elastic correction seat 5, and the inner end of the guide central shaft 9 is movably inserted into the center of the adjusting sleeve 11.
