Description

Technical Field

[0001] This utility model relates to the field of drilling rig technology, specifically to a stable sliding structure for a drilling rig. Background Technology

[0002] Drilling rigs are the most commonly used machines in drilling engineering. There are various types of drilling rigs, such as water well drilling rigs, exploration drilling rigs, and crawler hydraulic drilling rigs. The structures of various drilling rigs are generally similar, with the power head being adapted to the specific construction needs. The main structure of a drilling rig includes the rig body base, carriage, slide block, and power head. The rig body base can be considered the main support of the machine, where various components are installed. The carriage is mounted on the rig body base and allows for switching between horizontal and vertical positions. Some drilling rigs have carriages that can slide relative to the rig body. The slide block is mounted on the carriage and can slide along it. The power head is mounted on the slide block and moves with it.

[0003] Existing patent CN202321114205.3 discloses a stable sliding structure for a drilling rig, including a slide frame and a slide base; the slide base is slidably mounted on the slide frame, slide rails are provided on both sides of the slide frame along the length direction, and sliders and pulleys are fixedly provided on both sides of one side of the slide base; the sliders are provided with slide grooves, which cooperate with the protrusions on the slide rails; the pulleys are in rolling cooperation with the outer surface of the slide rails.

[0004] In the actual implementation of the aforementioned patent, the presence of significant dust and dirt at construction sites easily causes debris to splash and adhere to the slide rail. This allows impurities to easily enter between the slider and the slide rail as the slider slides, accelerating slider wear. Furthermore, once the pulleys wear out, they cannot maintain proper contact with the slide rail and must be replaced, resulting in waste. Therefore, we propose a stable sliding structure for drilling rigs. Utility Model Content

[0005] The purpose of this invention is to provide a stable sliding structure for drilling rigs, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable sliding structure for a drilling rig, including a connecting frame, slide rails fixed on both sides of the connecting frame, a suitable slider fitted on the outer wall of the slide rails, a connecting plate provided on one side of the connecting frame, a connecting block fixed on one side wall of the slider, and the outer ends of the two connecting blocks fixedly connected to the connecting plate.

[0007] The slider has three side walls at both ends hinged with shovels, and a spring is fixed to one side wall of each shovel. The outer end of the spring is fixedly connected to the corresponding position of the outer wall of the slider.

[0008] By adopting the above technical solution, the connecting plate is connected to the drilling rig. During the lifting and lowering process, the drilling rig slides stably along the slide rail by sliding the slider. At the same time, during the sliding process, the scraper can remove the impurities adhering to the guide rail, which helps to avoid the impurities from affecting the slide rail and the slider. The spring can push the scraper to fit against the slide rail, so that after the scraper wears, it can automatically fit against the rail under the pushing effect of the spring, thus ensuring the effect of removing impurities.

[0009] In a preferred embodiment of this utility model, a carrier block is connected to each of the four corners of the back of the connecting plate. A frame is fixedly connected to the outer end of the carrier block. A pulley is rotatably installed in the inner cavity of the frame. During the up-and-down movement of the drilling rig, the pulley can slide against the outer wall of the slide rail, thereby further improving the stability of the up-and-down movement.

[0010] In a preferred embodiment of this utility model, a sliding groove is provided at each of the four corners of the back of the connecting plate. A screw is rotatably installed in the inner cavity of the sliding groove. A matching threaded slider is fitted on the outer wall of the screw. The outer wall of the threaded slider is fixedly connected to the carrier block. By rotating the screw, the threaded slider can be moved, thereby driving the pulley to adjust its position. This allows for adjustment after the outer wall of the pulley wears down, ensuring the fit between the pulley and the slide rail, thus eliminating the need for direct replacement and saving costs.

[0011] In a preferred embodiment of this utility model, one end of the screw movably passes through the connecting plate and is fixedly connected to a hexagonal rotating block. The hexagonal rotating block makes it convenient to drive the hexagonal rotating block to rotate with the help of tools, thereby driving the screw to rotate and improving the convenience of operation.

[0012] In a preferred embodiment of this utility model, the connecting plate has connecting holes on both the top and bottom surfaces, which facilitates the connection between the connecting plate and the drilling rig.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The stable sliding structure of the drilling rig in this application has shovels hinged to the outer wall of the slider for heat dissipation. During the up-and-down sliding process of the slider, the shovels can remove impurities adhering to the guide rail, thus helping to avoid the impurities from affecting the guide rail and slider. The spring can push the shovels to fit against the guide rail, so that after the shovels wear, they can automatically fit against the guide rail under the push of the spring, thus ensuring the effect of removing impurities.

[0015] Rotating the screw can drive the threaded slider to move, thereby adjusting the position of the pulley. This allows for adjustment even after the outer wall of the pulley wears down, ensuring the proper fit between the pulley and the slide rail, eliminating the need for direct replacement and saving costs.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a stable sliding structure for a drilling rig, including a connecting frame 1, with slide rails 11 fixed on both sides of the connecting frame 1, and a suitable slider 3 fitted on the outer wall of the slide rail 11. A connecting plate 2 is provided on one side of the connecting frame 1, and a connecting block 33 is fixed on one side wall of the slider 3. The outer ends of the two connecting blocks 33 are fixedly connected to the connecting plate 2.

[0026] The three side walls at both ends of the slider 3 are hinged with shovel plates 31, and a spring 32 is fixed to one side wall of the shovel plate 31. The outer end of the spring 32 is fixedly connected to the corresponding position of the outer wall of the slider 3.

[0027] In actual use, the connecting plate 2 is connected to the drilling rig. During the lifting and lowering process of the drilling rig, the slider 3 slides along the slide rail 11 to achieve stable sliding. At the same time, during the sliding process, the scraper plate 31 can remove the impurities adhering to the guide rail 11, which helps to avoid the impurities from affecting the slide rail 11 and the slider 3. The spring 32 can push the scraper plate 31 to fit against the slide rail 11, so that after the scraper plate 31 is worn, it can automatically fit against the spring 32, thereby ensuring the effect of removing impurities.

[0028] Furthermore, the connecting plate 2 has connecting holes 21 on both the top and bottom surfaces. The connecting holes 21 facilitate the connection between the connecting plate 2 and the drilling rig.

[0029] like Figure 1 and 2 As shown in Figure 3, each of the four corners of the back of the connecting plate 2 is connected to a carrier block 22. The outer end of the carrier block 22 is fixedly connected to a frame, and a pulley 23 is rotatably installed in the inner cavity of the frame.

[0030] During the up-and-down movement of the drilling rig, the pulley 23 can slide against the outer wall of the slide rail, thereby further improving the stability of the lifting and sliding.

[0031] Furthermore, each of the four corners of the back of the connecting plate 2 is provided with a sliding groove 24. A screw 25 is rotatably installed in the inner cavity of the sliding groove 24. A matching threaded slider 26 is fitted on the outer wall of the screw 25. The outer wall of the threaded slider 26 is fixedly connected to the carrier block 22.

[0032] Rotating the screw 25 can drive the threaded slider 26 to move, thereby driving the pulley 23 to adjust its position. This allows for adjustment even after the outer wall of the pulley 23 wears down, ensuring the fit between the pulley 23 and the slide rail 11, thus eliminating the need for direct replacement and saving costs.

[0033] Furthermore, one end of the screw 25 movably passes through the connecting plate 2 and is fixedly connected to a hexagonal rotating block. The hexagonal rotating block makes it easy to rotate with the help of tools, thereby driving the screw 25 to rotate, which improves the convenience of operation.

[0034] The implementation principle of the stable sliding structure of the drilling rig in this application is as follows: In actual use, the connecting plate 2 is connected to the drilling rig. During the lifting and lowering process of the drilling rig, the slider 3 slides along the slide rail 11 for stable sliding. At the same time, during the sliding process, the scraper plate 31 can remove the impurities adhering to the guide rail 11, thereby helping to avoid the impurities from affecting the slide rail 11 and the slider 3. The spring 32 can push the scraper plate 31 to fit against the slide rail 11, so that after the scraper plate 31 wears, it can automatically fit under the pushing effect of the spring 32, thereby ensuring the removal of impurities. At the same time, during the lifting and lowering process of the drilling rig, the pulley 23 can slide against the outer wall of the slide rail, thereby further improving the stability of the lifting and sliding. After the pulley 23 wears, the screw 25 can drive the threaded slider 26 to move, thereby driving the pulley 23 to adjust its position. Thus, after the outer wall of the pulley 23 wears, the adjustment can be achieved to ensure the fit between the pulley 23 and the slide rail 11, so as not to directly replace it and save costs.

[0035] Furthermore, the components included in the stable sliding structure of the drilling rig of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching monitoring computer and power supply, are connected by wires. The specific connection method should refer to the working principle below, and the electrical connection between each electrical component is completed in the order of operation.
