Description

Technical Field

[0001] This utility model relates to the technical field of drill pipe cleaning equipment, specifically a drill pipe cleaning device for geological drilling equipment. Background Technology

[0002] Geological drilling equipment (also known as drilling equipment) is commonly used in the field of mineral exploration to assess mineral resources in geology, determine the distribution location, thickness, and approximate quality of mineral resources, and facilitate their subsequent rational development and utilization.

[0003] Drilling equipment mainly consists of a drilling rig, mud pump and mud purification equipment, mud mixer, and drilling tower. During operation, the drilling rig drives drill rods into the formation to obtain geological information at the desired location. Because mud is added to the drill rods during drilling, and they may come into contact with groundwater, a large amount of mud and water adheres to the surface of the drill rods when they are pulled out. If these drill rods are directly pulled out of the ground and disassembled for storage, the surface is easily contaminated with soil. This not only contaminates the drill rod surface and increases the cleaning workload for subsequent reuse, but also causes wear and tear on the drill rod surface during transportation, as the soil contains hard minerals.

[0004] For example, the drill rod cleaning device for geological drilling equipment disclosed in Chinese Patent Publication No. CN221096482U, the cleaning device drives the adjusting block to rotate on the support frame. As the adjusting block rotates, it pulls the hinge points of the two first horizontal rods and the second horizontal rod away from each other. In this way, the connecting clamps connected to the two second horizontal rods will move closer to each other and clamp the drill rod. When the rubber clamps in the clamps are close to the drill rod, the drill rod can be pulled upward. As the drill rod moves, the mud and water on the drill rod will be cleaned off by the rubber clamps.

[0005] In geological engineering, drilling equipment often uses a single or double spiral rod to enhance the rotation of the soil. However, the rubber clips in the aforementioned equipment are fixed on the clamping plate and cannot be adjusted. As a result, the fixed position of the rubber clips means that only the soil at the spiral can be scraped off, and the area between the outer wall of the rod and the spiral cannot be reached. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drill rod cleaning device for geological drilling equipment, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a drill rod cleaning device for a geological drilling apparatus, comprising a cleaning platform, wherein a fixing block for limiting both ends of the drill rod body is provided on the cleaning platform, the fixing block is detachably connected to the cleaning platform, the drill rod body rotates within the fixing block, and a scraping module for cleaning is provided on one side of the drill rod body;

[0008] The scraping module includes guide slides fixedly installed at both ends of the cleaning platform. A guide slider for installing the cleaning shaft is provided on one side of the guide slide. A rotating seat for connecting a snap-fit ​​plate is installed on the cleaning shaft. A snap-fit ​​groove is provided in the snap-fit ​​plate and a limiting rod for connection is symmetrically arranged. A connecting rod for connecting a movable sleeve is provided at the other end of the limiting rod.

[0009] A further improvement of this utility model is that: the guide slide is slidably connected to the guide slider through its inner sliding groove; the cleaning shaft is rotatably connected to the rotating seat and the rotating seat is welded to its upper retaining plate; the retaining plate is detachably connected to the limiting rod through its inner retaining groove; and the connecting rod is welded to the movable sleeve and connected to the limiting rod.

[0010] A further improvement of this utility model is that: a connecting key is provided on the cleaning shaft, and the cleaning shaft is connected to the cleaning scraper key on it via the connecting key; a rubber scraper for scraping is provided on the outer wall end face of the cleaning scraper; at the initial position of the cleaning scraper, i.e., at the initial position of the guide slider in the sliding groove, the rubber scraper contacts the outer wall between the rod body and the helical edge on the drill rod body; when the rubber scraper cleans the helical edge on the drill rod body, because the helical edge protrudes relative to the outer wall of the rod body, the rubber scraper is pushed by a force, so the guide slider is pushed towards one end of the connecting rod in the sliding groove, thereby the rubber scraper completes the self-adjustment and self-adaptation of the cleaning position of the drill rod body.

[0011] A further improvement of this utility model is that: the movable sleeve has an internal thread groove for threaded connection of the adjusting screw, and the adjusting screw has symmetrically positioned positioning blocks at both ends, which are installed in the guide slide. One end of the cleaning shaft is connected to the drive motor through a coupling. The drive motor moves simultaneously with the cleaning shaft and the guide slide. If the drill rod body rotates, in order to improve the scraping effect of the surface soil, the rotation direction of the rubber scraper driven by the drive motor should be opposite to the rotation of the drill rod body. Therefore, in the actual cleaning process, after the rubber scraper has repeatedly scraped a certain part of the drill rod body, the adjusting screw is rotated manually or by driving force to complete the forward and backward movement of the movable sleeve.

[0012] A further improvement of this utility model is that a spring for resetting and compression is provided between the positioning block and the adjacent guide slider; the rubber scraper completes the self-adjustment and self-adaptation of the position of cleaning the drill rod body. The premise of self-adaptation is that when the rubber scraper is not squeezed by the spiral edge, the spring connected to the guide slider causes the connected guide slider and the rubber scraper on it to reset under the action of elastic force, thereby completing self-adaptation and self-adjustment.

[0013] A further improvement of this utility model is that the top of the cleaning platform and directly below the cleaning scraper has a concave arc surface, and a linkage rod is inserted between two adjacent cleaning scrapers.

[0014] Beneficial effects

[0015] This invention provides a drill pipe cleaning device for geological drilling equipment. Compared with the prior art, it has the following advantages:

[0016] 1. The drill rod cleaning equipment used in this geological drilling device, when cleaning the spiral edge on the drill rod body with a rubber scraper, because the spiral edge protrudes relative to the outer wall of the rod body, the rubber scraper is pushed by a force, so the guide slider is pushed towards one end of the connecting rod in the sliding groove, and then reset under the action of the subsequent spring, thereby the cleaning equipment completes the self-adjustment and self-adaptation of the position of cleaning the drill rod body.

[0017] 2. The drill rod cleaning equipment used in this geological drilling device is connected to the cleaning scraper key on the cleaning shaft via a connecting key. The moving sleeve drives the cleaning scraper to move back and forth via the connecting rod without interfering with the rotation of the cleaning shaft. Therefore, the rubber scraper can clean the drill rod body at various positions, removing the drill bit and drill tail. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4 This utility model provides three technical solutions:

[0031] Example 1:

[0032] A drill rod cleaning device for a geological drilling apparatus includes a cleaning platform 1. The cleaning platform 1 is provided with fixing blocks 2-1 for limiting both ends of the drill rod body 2. The fixing blocks 2-1 are detachably connected to the cleaning platform 1. The drill rod body 2 rotates within the fixing blocks 2-1. A scraping module for cleaning is provided on one side of the drill rod body 2.

[0033] The scraping module includes guide slides 3 fixedly installed at both ends of the cleaning platform 1. A guide slider 3-2 for installing the cleaning shaft 3-1 is provided on one side of the guide slide 3. A rotating seat 3-4 for connecting the clamping plate 3-3 is installed on the cleaning shaft 3-1. A limiting rod 3-3b for connection is symmetrically arranged in the clamping groove 3-3a provided in the clamping plate 3-3. A connecting rod 3-3c for connecting the moving sleeve 4 is provided at the other end of the limiting rod 3-3b.

[0034] The guide slide 3 is slidably connected to the guide slider 3-2 through its inner sliding groove. The cleaning shaft 3-1 is rotatably connected to the rotating seat 3-4 and the rotating seat 3-4 is welded to its upper retaining plate 3-3. The retaining plate 3-3 is detachably connected to the limiting rod 3-3b through its inner retaining groove 3-3a. The connecting rod 3-3c is welded to the movable sleeve 4 and connected to the limiting rod 3-3b.

[0035] A connecting key 3-1a is provided on the cleaning shaft 3-1, and the cleaning shaft 3-1 is connected to the cleaning scraper 3-1b above it via the connecting key 3-1a. A rubber scraper 3-1c for scraping is provided on the outer wall end face of the cleaning scraper 3-1b.

[0036] In this embodiment, at the initial position of the cleaning scraper 3-1b, i.e., at the initial position of the guide slider 3-2 in the sliding groove, the rubber scraper 3-1c contacts the outer wall between the rod body and the helical edge on the drill rod body 2. When the rubber scraper 3-1c cleans the helical edge on the drill rod body 2, because its helical edge protrudes relative to the outer wall of the rod body, the rubber scraper 3-1c is pushed by a force. Therefore, the guide slider 3-2 is pushed towards one end of the connecting rod 3-3c in the sliding groove, so that the rubber scraper 3-1c completes the self-adjustment and self-adaptation of the cleaning position of the drill rod body 2.

[0037] Example 2:

[0038] Based on Embodiment 1: The movable sleeve 4 has an internal thread groove for threaded connection of the adjusting screw 4-1, and the adjusting screw 4-1 is symmetrically provided with a limiting positioning block 4-2 installed in the guide slide 3 at both ends, and one end of the cleaning shaft 3-1 is connected to the drive motor 3-1d through a coupling.

[0039] It should be noted that the drive motor 3-1d moves simultaneously with the cleaning shaft 3-1 and the guide slider 3-2. If the drill rod body 2 rotates, in order to improve the scraping effect of the surface soil, the rotation direction of the drive motor 3-1d driving the rubber scraper 3-1c should be opposite to the rotation of the drill rod body 2.

[0040] In this embodiment, the internal thread groove inside the movable sleeve 4 is threadedly connected to the adjusting screw 4-1. Therefore, during the rotation of the adjusting screw 4-1, the movable sleeve 4 on it slides back and forth. It should be noted that:

[0041] In Embodiment 1, a connecting key 3-1a is provided on the cleaning shaft 3-1, and the cleaning shaft 3-1 is connected to the cleaning scraper 3-1b above it via the connecting key 3-1a. Then, the moving sleeve 4 drives the cleaning scraper 3-1b to move back and forth via the connecting rod 3-3c without interfering with the rotation of the cleaning shaft 3-1. Thus, the rubber scraper 3-1c is used to clean the drill rod body 2 at various positions to remove the drill bit and drill tail.

[0042] Therefore, in the actual cleaning process, after the rubber scraper 3-1c has repeatedly scraped a certain part of the drill rod body 2, the adjusting screw 4-1 is rotated by human intervention or driving force to complete the back-and-forth movement of the moving sleeve 4.

[0043] Example 3:

[0044] Based on Embodiment 1 and Embodiment 2: A spring 5 for resetting and compression is provided between the positioning block 4-2 and the adjacent guide slider 3-2.

[0045] In Example 1, the rubber scraper 3-1c completes the self-adjustment and self-adaptation of the cleaning position of the drill rod body 2. The premise of self-adaptation is that when the rubber scraper 3-1c is not squeezed by the spiral edge, the spring 5 connected to the guide slider 3-2 causes the connected guide slider 3-2 and the rubber scraper 3-1c on it to reset due to the elastic force, thereby completing self-adaptation and self-adjustment.

[0046] The top of the cleaning platform 1 and directly below the cleaning scraper 3-1b has a concave arc surface, and a linkage rod 3-1b-1 is inserted between two adjacent cleaning scrapers 3-1b.

[0047] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
