Description

Technical Field

[0001] The present application relates to the technical field of drilling rigs, and in particular to a rotary bracket for drilling rigs. Background Art

[0002] A drilling rig is a mechanical device composed of machines, units and mechanisms. It is used to drive drill tools underground to obtain physical geological data during the exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.). It can be used to drill rock cores, ore cores, rock cuttings, gas samples, liquid samples, etc. to explore the underground geology and mineral resources.

[0003] However, during the actual drilling process, the drilling rig often needs to achieve multi-angle drilling to meet the drilling needs. Every time the drilling angle is changed, the angle of the drill bit needs to be adjusted. The drilling rig is usually turned by removing the power head and other components of the drilling rig from the support track of the drilling rig, reversing the direction, and then reinstalling them. Since drilling rigs are mostly used for underground drilling in coal mines, the above-mentioned drilling rig reversal method is not only time-consuming and labor-intensive, but also cannot be completed in narrow tunnels. The drilling rig also needs to be moved to a specific location and special lifting equipment needs to be used to complete it, thereby reducing the drilling efficiency of the drilling rig.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0026] refer to Figures 1 to 4 The present application provides a rotary support for a drilling rig, comprising:

[0027] The lower support frame 100 is arranged on a reference surface, and an upper support frame 200 for installing a drilling rig is rotatably provided in the middle of the top surface of the lower support frame 100; wherein, through the connection between the lower support frame 100 and the reference surface, the stability of the upper support frame 200 rotatably connected to the lower support frame 100 and the drilling rig installed on the upper support frame 200 is improved. When it is necessary to adjust the drilling angle of the drilling rig, it is only necessary to rotate the upper support frame 200 to realize the adjustment of the drill bit azimuth of the drilling rig installed on the upper support frame 200 through the upper support frame 200, thereby realizing the adjustment of the drilling angle of the drilling rig, and the adjustment process is easy to operate, thereby improving the adjustment efficiency of the drilling angle of the drilling rig.

[0028] Positioning assembly 300 includes a positioning cylinder 301 and a positioning rod 302 that matches the positioning cylinder 301. The positioning cylinder 301 is mounted on the periphery of the upper support frame 200. One end of the positioning rod 302 passes through the positioning cylinder 301 and connects to the reference surface. When the drilling angle of the drilling rig is adjusted to the desired position, one end of the positioning rod 302 passes through the positioning cylinder 301, connecting the bottom end of the positioning rod 302 to the reference surface. This effectively positions the upper support frame 200, thereby ensuring the desired drilling angle of the drilling rig is fixed at the desired position, improving the stability of the drilling process and the accuracy of the drilling angle adjustment.

[0029] The present invention provides a rotary support for drilling rigs, by installing the drilling rig on the upper support frame 200, and the upper support frame 200 is rotatably set on the top surface of the lower support frame 100, and the lower support frame 100 is set on the reference surface, so that the lower support frame 100 supports the upper support frame 200 and the drilling rig on the upper support frame 200. By rotating the upper support frame 200, the drilling angle of the drilling rig on the upper support frame 200 can be adjusted. When the drill bit of the drilling rig rotates to the desired drilling position, the positioning rod 302 is inserted into the positioning cylinder 301 on the side of the upper support frame 200, and the bottom end of the positioning rod 302 is connected to the reference surface, thereby fixing the upper support frame 200 and preventing the upper support frame 200 from rotating again, thereby fixing the drilling position of the drill bit. The adjustment of the drilling angle of the above-mentioned drill bit is more time-saving and labor-saving, and the adjustment range of the drilling angle is wide and accurate, thereby improving the adjustment efficiency of the drilling angle of the drilling rig and the drilling efficiency of the drilling rig.

[0030] In some embodiments, reference Figure 3 The positioning assembly 300 in the present application also includes a circular positioning groove 303, a positioning block 304 matching the positioning groove 303, and a limit unit 305; specifically, the positioning groove 303 is arranged on the upper surface of the lower support frame 100 and coincides with the center of the lower support frame 100 and the upper support frame 200, so as to ensure the stability of the supporting connection between the upper support frame 200, the positioning groove 303 and the lower support frame 100, thereby ensuring the stability of the drilling process of the drilling rig.

[0031] In addition, a connecting rod 201 is provided on the outer peripheral wall of the upper support frame 200. The end of the connecting rod 201 away from the upper support frame 200 is connected to a positioning block 304 disposed in a positioning groove 303. The positioning block 304 can slide in the positioning groove 303. A limiting unit 305 passes through the positioning block 304 and the positioning groove 303 to fix the positioning block 304 and the positioning groove 303 together. The provision of the connecting rod 201 and the positioning block 304 increases the contact points between the upper support frame 200 and the lower support frame 100, thereby improving the stability of the upper support frame 200 and the drilling rig supported thereon.

[0032] In the above embodiment, the upper support frame 200 rotates so that the positioning block 304 connected to the connecting rod 201 on the lower surface of the upper support frame 200 slides in the positioning groove 303, thereby improving the rotation stability of the upper support frame 200.

[0033] In some embodiments, reference Figures 1 to 4The limiting unit 305 in the present application includes a limiting rod. Specifically, a plurality of first through holes 3031 are respectively defined along the circumference of the two opposing side walls of the positioning slot 303. The positioning block 304 is provided with second through holes 3041 that match the first through holes 3031. One end of the limiting rod sequentially passes through one of the first through holes 3031, the second through hole 3041, and the other first through hole 3031. The number of first through holes 3031 on the same side wall of the positioning slot 303 can be set based on the actual required drilling angle to meet the drilling angle requirements. Therefore, this application does not specifically limit this.

[0034] In the above embodiment, when the upper support frame 200 drives the drilling rig thereon to rotate to the drilling position required by the drilling rig, one end of the limit rod is sequentially passed through one of the first through holes 3031, the second through hole 3041 and the other first through hole 3031, thereby preventing the positioning block 304 from sliding in the positioning groove 303 as the upper support frame 200 rotates, thereby improving the stability of the upper support frame 200 and the drilling rig thereon.

[0035] In some embodiments, reference Figure 1 、 Figure 2 and Figure 4 In the present application, the positioning cylinder 301 is provided with an internal thread 3011 along its height direction, and the outer wall of the positioning rod 302 is provided with an external thread 3021 that matches the internal thread 3011. The external thread 3021 on the positioning rod 302 and the internal thread 3011 on the inner wall of the positioning cylinder 301 allow the positioning rod 302 to position the upper support frame 200 more stably, thereby improving the stability of the upper support frame 200 and the drilling rig thereon.

[0036] In some embodiments, reference Figure 3 , the lower support frame 100 in this application is provided with a bearing 101, and the lower surface of the middle part of the upper support frame 200 is provided with a support shaft 202 matching the bearing 101, and the bearing 101 is sleeved on the support shaft 202; wherein, the support shaft 202 connected to the lower surface of the upper support frame 200 rotates in the bearing, thereby realizing the rotation of the upper support frame 200 and the drilling rig on the upper support frame 200, making the rotation of the upper support frame 200 and the adjustment of the drilling angle of the drilling rig thereon more time-saving and labor-saving, thereby improving the adjustment efficiency of the drilling angle of the drilling rig and improving the drilling efficiency of the drilling rig.

[0037] In addition, a push rod 203 is provided on the outer wall of the upper support frame 200. The upper support frame 200 can be rotated by pushing the push rod 203. The setting of the push rod 203 facilitates pushing the upper support frame 200, thereby making the rotation of the upper support frame 200 more labor-saving.

[0038] In some embodiments, reference Figure 1 、 Figure 2 and Figure 4 In the present application, two vertical mounting cylinders 204 are disposed opposite each other on the top surface of one side of the upper support frame 200. A rotating rod 205 is rotatably disposed on the upper support frame 200, and two fixing rods 2051 are vertically disposed on the rod body of the rotating rod 205 near its two ends. The vertical mounting cylinders 204, the rotating rod 205, and the fixing rods 2051 are used to mount and secure a drilling rig. Since the rotating rod 205 is rotatably disposed on the upper support frame 200, after the drilling rig is secured to the vertical mounting cylinder 204, the rotating rod 205 rotates to bring the rotating rod 205 closer to the drilling rig mounted on the vertical mounting cylinder 204 and further secure the drilling rig, thereby improving the stability of the drilling rig. In addition, the angle between the rotating rod 205 and the top surface of the upper support frame 200 can be adjusted according to the size of the drilling rig (for example, the outer diameter of the drilling rig's shell) until the fixing rod 2051 is close to the drilling rig installed on the vertical mounting tube 204, so that the fixing rod 2051 can further fix drilling rigs of different specifications, thereby improving the wide applicability of the rotating bracket for drilling rigs.

[0039] In some embodiments, reference Figure 1 、 Figure 2 and Figure 4 The bottom of the lower support frame 100 in the present application is provided with a fixing plate 102, and a threaded through hole 1021 matching the anchor bolt is opened on the fixing plate 102. The two ends of the anchor bolt respectively pass through the threaded through hole 1021 and extend below the reference surface to fix the lower support frame 100 on the reference surface, thereby improving the stability of the lower support frame 100 on the reference surface, thereby improving the stability of the upper support frame 200 and the drilling rig on the upper support frame 200, and ensuring the stability of the drilling rig during the drilling process.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
