Description

Technical Field

[0001] This utility model relates to the technical field of drilling rig outriggers, and more particularly to adjustable drilling rig outriggers. Background Technology

[0002] The base of the drilling rig is relatively large and heavy. The outriggers of the drilling rig mainly serve to support and stabilize the drilling rig, ensuring that the center of gravity of the drilling rig is stable during construction and preventing the drilling rig from tipping over.

[0003] Currently, most drilling rigs use hydraulic telescopic outriggers. During the extension and retraction process, the power of the outriggers is supplied by telescopic cylinders. The use of this type of outrigger requires the drilling rig to be relatively large in order to ensure the design space for the telescopic cylinders and to allow the telescopic cylinders and their corresponding hydraulic lines to work properly.

[0004] However, using telescopic cylinders to control the outriggers to support the entire drilling rig is time-consuming and laborious, making it inconvenient to use the telescopic cylinders. Since the telescopic cylinders are exposed to the outside, and the drilling rig generates a lot of mud and water during operation, the mud and water will splash onto the telescopic cylinders. Therefore, after the telescopic cylinders have finished working, they need to be cleaned manually. This process is inconvenient and laborious. Summary of the Invention

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] The adjustable drilling rig outriggers of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, the adjustable drilling rig outriggers of this embodiment may include a drilling rig support frame 100 for supporting the drilling rig. Support devices 200 for supporting the drilling rig support frame 100 are fixedly installed at both ends of the drilling rig support frame 100. A protective device 300 for protecting the support device 200 is provided within the support device 200. The support device 200 includes a support assembly 210 fixedly installed on the drilling rig support frame 100. An outrigger assembly 220 for supporting the drilling rig support frame 100 is provided within the support assembly 210. A protective assembly 310 for protecting the support assembly 210 is provided within the support assembly 210. A spring 320 for adjusting the protective assembly 310 by extending and retracting with the outrigger assembly 220 is fixedly installed at the top of the protective assembly 310. There are four 0; therefore, when it is necessary to adjust the support of the drilling rig on the drilling rig support frame 100, firstly, according to the terrain where the drilling rig is located, when replacing the accessory 223 at the bottom of the support plate 222, the two clips 224 at the top of the accessory 223 can be locked in the support plate 222, and then the accessory 223 can be fixed by bolts 225 passing through the clips 224 and threadedly connecting with the support plate 222; then the hydraulic rod 221 moves the support plate 222 closer to the ground; at this time, the four springs 320 on the limiting plate 311 can always keep the protective frame 312 protecting the hydraulic rod 221 under its own elasticity, so as to prevent the mud generated by the drilling rig from splashing onto the hydraulic rod 221 during operation and affecting the operation of the hydraulic rod 221; thus, it is not necessary to clean the hydraulic rod 221 after the drilling rig has finished drilling. Example

[0030] Reference manual attached Figure 2 and Figure 3 It can be seen that the difference between Embodiment 2 and Embodiment 1 is as follows:

[0031] The bottom end of the drilling rig support frame 100 is provided with a track 101 for driving the drilling rig support frame 100 to move. There are two tracks 101, which are symmetrically distributed at the bottom end of the drilling rig support frame 100. This is to facilitate the use of the two tracks 101 to control the drilling rig on the drilling rig support frame 100 to move to the location where drilling is required.

[0032] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the support assembly 210 includes support columns 211 fixedly installed on the drilling rig support frame 100, and there are four support columns 211, which are distributed in a rectangular array at the four corners of the drilling rig support frame 100.

[0033] Furthermore, the support column 211 has an elongated groove 212 for placing the support leg assembly 220, and a storage slot 213 for storing the protective assembly 310. The storage slot 213 is located outside the elongated groove 212, and the cross-section of the storage slot 213 is stepped, thus preventing the protective assembly 310 from falling out of the storage slot 213.

[0034] Furthermore, the outrigger assembly 220 includes a hydraulic rod 221 disposed in the elongated slot 212 for telescopic extension, and the hydraulic rod 221 passes through the bottom end of the support column 211; a support plate 222 for supporting the drilling rig support frame 100 is fixedly installed at the bottom end of the hydraulic rod 221.

[0035] Furthermore, the bottom end of the support plate 222 is provided with an accessory 223 for protecting the support plate 222. The accessory 223 can be a rubber pad for use on flat ground or a steel nail claw for use on muddy ground. The top end of the accessory 223 is fixedly installed with a locking strip 224 for locking the accessory 223 into the support plate 222. The side wall of the support plate 222 is provided with bolts 225 for fixing the locking strip 224 into the support plate 222. Therefore, when it is necessary to replace the accessory 223 at the bottom end of the support plate 222 according to the terrain where the drilling rig is located, the two locking strips 224 at the top end of the accessory 223 can be locked into the support plate 222, and the accessory 223 can be fixed by the bolts 225 passing through the locking strips 224 and connecting them with the threaded connection between the bolts 225 and the support plate 222.

[0036] In one embodiment of this utility model, such as Figure 4 and Figure 5As shown, the protective assembly 310 includes a limiting plate 311 for vertical movement disposed within the receiving slot 213. The shape and size of the limiting plate 311 are the same as those of the receiving slot 213, thus ensuring that the protective frame 312 can be moved out of the receiving slot 213. Four springs 320 are arranged in a circumferential array at the top of the limiting plate 311. A protective frame 312 for protecting the hydraulic rod 221 is fixedly installed at the bottom of the limiting plate 311. A useful spring is fixedly installed at the bottom of the protective frame 312. To prevent the protective frame 312 from moving completely into the storage slot 213, the second limiting plate 313 is used; thus, when the support device 200 adjusts and supports the drilling rig support frame 100, the four springs 320 located on the first limiting plate 311 can always keep the protective frame 312 protecting the hydraulic rod 221 under their own elastic action, so as to prevent the mud generated by the drilling rig during operation from splashing onto the hydraulic rod 221 and affecting the operation of the hydraulic rod 221; thus, it is not necessary to clean the hydraulic rod 221 after the drilling rig has finished drilling.

[0037] In summary, the adjustable drilling rig outriggers of this embodiment allow for adjustments to the drilling rig support frame 100 when necessary. Firstly, when replacing the accessory 223 at the bottom of the support plate 222 according to the terrain, the two locking strips 224 at the top of the accessory 223 can be engaged within the support plate 222. Then, bolts 225 are threaded through the locking strips 224 and connected to the support plate 222, thus securing the accessory 223. Next, the hydraulic rod 221 moves the support plate 222 closer to the ground. At this time, the four springs 320 on the limiting plate 311 maintain the protective frame 312 protecting the hydraulic rod 221, preventing mud and dirt generated during drilling from splashing onto the hydraulic rod 221 and affecting its operation. Consequently, cleaning of the hydraulic rod 221 is unnecessary after drilling is complete.
