Description

Technical Field

[0001] This utility model belongs to the field of engineering equipment and relates to a drilling rig, and more particularly to a drilling rig power head translation mechanism. Background Technology

[0002] A drilling rig is a mechanical device used in exploration or mineral resource development to drive drilling tools into the ground to obtain physical geological data.

[0003] Existing drilling rig structures, such as the fully hydraulic power head drilling rig disclosed in the Chinese Patent Database (application number: 202210653498.6) suitable for drilling loose and fractured formations, include a base frame assembly, a centering clamp, a pipe rolling machine, a power head assembly, a drilling rig guide rail, a fixed pulley block, a support cylinder, and a feed cylinder. The power head of the power head assembly is fixedly connected to the feed cylinder and slidably connected to the drilling rig guide rail. The power head assembly consists of a power head, a hexagonal guide rail sliding sleeve, and a power head support plate assembly. A hydraulic clamping and hydraulic vibration impact device is installed inside the power head of the power head assembly. A hexagonal guide rail sliding sleeve is welded to the outer shell of the power head support plate assembly. The power head support plate assembly is hinged to the power head. The power head support plate assembly is fixedly connected to the feed cylinder by screws.

[0004] In actual use, drilling rigs are generally mounted directly on vehicles for movement. In the aforementioned drilling rigs, the power head can only move up, down, and slide. When continuous drilling is required in the horizontal direction, the position of the entire drilling rig needs to be adjusted by moving the vehicle. This process involves vehicle movement, re-drilling and repositioning, and other operations, which are quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a user-friendly drilling rig power head translation mechanism.

[0006] The objective of this utility model can be achieved through the following technical solution: A drilling rig power head translation mechanism includes a bracket and a support plate disposed on the front side of the bracket. A first hydraulic cylinder for driving the support plate to rise and fall is provided on the bracket. The power head is disposed on the front side of the support plate. The feature is that a mounting seat is provided between the power head and the support plate, and the power head is fixed on the mounting seat. At least one guide sleeve is horizontally fixed on both the upper and lower sides of the mounting seat, and the axis of the guide sleeve extends to the left and right. A single guide rod is inserted into several guide sleeves in the same row. The shape and size of the guide rod are matched with the inner hole of the guide sleeve, and both ends of the guide rod are fixedly connected to the support plate. A second hydraulic cylinder for driving the mounting seat to translate left and right is also provided on the support plate.

[0007] With the cooperation of components such as the second hydraulic cylinder, guide sleeve, and guide rod, the power head can move independently in a small range in the left and right directions to perform continuous drilling. This eliminates the need to move the support during actual use, making it convenient and easy to use.

[0008] In the aforementioned drilling rig power head translation mechanism, the guide sleeve includes a sleeve and a copper sleeve coaxially fixed inside the sleeve. Both the sleeve and the copper sleeve are fitted onto the corresponding guide rod. The sleeve is fixedly connected to the mounting base. The inner diameter of the sleeve is larger than the outer diameter of the guide rod, and the shape and size of the inner hole of the copper sleeve match the guide rod. The guide sleeve slides against the guide rod through the copper sleeve. Because the copper sleeve itself has good self-lubricating and wear-resistant properties, it can form a stable oxide film in muddy environments to reduce the coefficient of friction and slow down wear, ensuring smooth left and right movement of the power head.

[0009] In the aforementioned drilling rig power head translation mechanism, the mounting base has mounting holes that match the sleeve running through it on both the left and right sides. The number of mounting holes and guide sleeves is the same, and the sleeve is inserted into and fixed in the corresponding mounting holes to facilitate the connection of the guide sleeve to the mounting base.

[0010] In the aforementioned drilling rig power head translation mechanism, an annular limiting seat is formed on the inner wall of the sleeve, and the limiting seat is coaxially arranged with the sleeve; an interference fit is formed between the outer wall of the copper sleeve and the inner wall of the sleeve, and a limiting component is also fixed inside the sleeve, with the two end faces of the copper sleeve respectively pressed against the corresponding limiting seat and the corresponding limiting component. This design ensures the copper sleeve is stably positioned within the sleeve, thereby improving operational stability.

[0011] In the aforementioned drilling rig power head translation mechanism, an annular positioning groove is provided on the inner wall of the sleeve, and the limiting component is a snap ring installed in the positioning groove.

[0012] As an alternative, in the aforementioned drilling rig power head translation mechanism, the limiting component is a retaining ring, and the retaining ring is threadedly connected to the inner wall of the corresponding sleeve.

[0013] In the aforementioned drilling rig power head translation mechanism, an annular flange is formed on the outer wall of the sleeve. The annular flange presses against the edge of the corresponding mounting hole, and the annular flange is fixed to the mounting base by a ring of screws.

[0014] In the aforementioned drilling rig power head translation mechanism, a connecting plate is vertically fixed on the front side of the support plate. There are two connecting plates arranged side by side. Two through holes are respectively set opposite to the two guide rods on the connecting plates. Both ends of the guide rods are external threaded posts that match the through holes. Each external threaded post is inserted into the corresponding through hole. Each external threaded post is screwed with a pressure cap, and the sides of the two connecting plates that are far apart are pressed against the corresponding pressure caps.

[0015] In the aforementioned drilling rig power head translation mechanism, the connecting plate is detachably fixed to the support plate by several bolts; the outer wall of the guide rod is formed with two annular shoulder surfaces, each shoulder surface is located between the two connecting plates, and the two shoulder surfaces on the same guide rod are pressed against the two connecting plates respectively to effectively enhance the positioning strength of the guide rod.

[0016] In the aforementioned drilling rig power head translation mechanism, the second hydraulic cylinder includes a second cylinder barrel and a second piston rod. The second piston rod is fixedly connected to one of the connecting plates, and the second cylinder barrel is fixed on the mounting base.

[0017] Compared with existing technologies, the power head translation mechanism of this drilling rig has the following advantages: 1. With the cooperation of components such as the second hydraulic cylinder, guide sleeve, and guide rod, the power head can move independently in a small range in the left and right directions to perform continuous drilling. In this way, there is no need to move the support during actual use, which has the advantages of being convenient and easy to use.

[0018] 2. The guide sleeve slides with the guide rod through a copper sleeve. Because the copper sleeve itself has good self-lubricating and wear-resistant properties, it can form a stable oxide film in muddy environments to reduce the coefficient of friction and slow down wear, ensuring smooth left and right movement of the power head.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Example 1: As Figure 1 As shown, the power head translation mechanism of this drilling rig includes a bracket 1 and a support plate 2 disposed on the front side of the bracket 1.

[0027] in, like Figure 1 , Figure 2 and Figure 5 As shown, the bracket 1 is equipped with a first hydraulic cylinder 3 for driving the support plate 2 to rise and fall. Specifically, the first hydraulic cylinder 3 is vertically arranged and located behind the support plate 2. The first hydraulic cylinder 3 includes a first cylinder barrel 3a and a first piston rod vertically arranged inside the first cylinder barrel 3a. The lower end of the first piston rod extends out of the first cylinder barrel 3a and is fixedly connected to the bracket 1. The first cylinder barrel 3a is fixedly connected to the support plate 2 through a connecting seat 4, so that the support plate 2 can be driven to rise and fall by sliding the first cylinder barrel 3a. Further, at least one roller 5 is rotatably installed on both the left and right sides of the connecting seat 4, and the axis of the roller 5 extends to the left and right. A strip-shaped raceway 1a is vertically formed on the bracket 1, and the cross-section of the strip-shaped raceway 1a is U-shaped and matches the roller 5. There are two strip-shaped raceways 1a, which are respectively arranged on the left and right sides of the connecting seat 4. The roller 5 is rolled in the corresponding strip-shaped raceway 1a to improve the sliding support of the first cylinder barrel 3a. In the actual product, each strip raceway 1a is provided with at least two rollers 5, and multiple rollers 5 in the same strip raceway 1a are vertically distributed.

[0028] The first hydraulic cylinder 3 is also provided with vertical guide shafts 6 on its left and right sides, and the two guide shafts 6 are arranged side by side, with the two shaped raceways 1a located between the two guide shafts 6. The guide shafts 6 are fixed on the bracket 1, and each guide shaft 6 is fitted with a sliding sleeve 7 that matches the guide shaft 6. Both sliding sleeves 7 are fixed to the support plate 2 to provide better support for the lifting and sliding of the support plate 2.

[0029] like Figure 2 and Figure 3 As shown, the power head 8 is located on the front side of the support plate 2, and a mounting base 9 is provided between the power head 8 and the support plate 2, with the power head 8 fixed on the mounting base 9. At least one guide sleeve 10 is horizontally fixed on both the upper and lower sides of the mounting base 9, and the axis of the guide sleeve 10 extends left and right. The same guide rod 11 passes through several guide sleeves 10 in the same row, that is, there are two guide rods 11, and the two guide rods 11 are arranged side by side. The shape and size of the guide rod 11 match the inner hole of the guide sleeve 10, and both ends of the guide rod 11 are fixed to the support plate 2; the support plate 2 is also provided with a second hydraulic cylinder 12 for driving the mounting base 9 to move left and right.

[0030] With the cooperation of components such as the second hydraulic cylinder 12, guide sleeve 10, and guide rod 11, the power head 8 can move independently in a small range in the left and right directions to perform continuous drilling. In this way, there is no need to move the support 1 during actual use, which has the advantages of being convenient and easy to use.

[0031] In this embodiment, like Figure 4As shown, the guide sleeve 10 has the following specific structure: The guide sleeve 10 includes a sleeve 10a and a copper sleeve 10b coaxially fixed inside the sleeve 10a. The inner hole of the copper sleeve 10b is the inner hole of the guide sleeve 10, and both the sleeve 10a and the copper sleeve 10b are fitted onto the corresponding guide rod 11. The sleeve 10a is fixedly connected to the mounting base 9, and the inner diameter of the sleeve 10a is larger than the outer diameter of the guide rod 11; the shape and size of the inner hole of the copper sleeve 10b are matched with the guide rod 11. The guide sleeve 10 slides with the guide rod 11 through the copper sleeve 10b. Since the copper sleeve 10b itself has good self-lubricating and wear-resistant properties, it can form a stable oxide film in a muddy environment to reduce the coefficient of friction and slow down wear, ensuring that the power head 8 moves smoothly left and right.

[0032] The connection between the mounting base 9 and the sleeve 10a is as follows: The mounting base 9 has mounting holes on both sides that match the sleeve 10a. The number of mounting holes and the position of the guide sleeve 10 are the same, and they correspond one-to-one. The sleeve 10a is inserted into and fixed in the corresponding mounting hole to facilitate the connection of the guide sleeve 10 to the mounting base 9. Further, an annular flange 10a1 is formed on the outer wall of the sleeve 10a, and the annular flange 10a1 and the corresponding sleeve 10a are coaxially arranged. The annular flange 10a1 presses against the edge of the corresponding mounting hole, and the annular flange 10a1 is fixed to the mounting base 9 by a ring of screws.

[0033] The connection between the copper sleeve 10b and the sleeve 10a is as follows: an annular limiting seat 10a2 is formed on the inner wall of the sleeve 10a, and the limiting seat 10a2 is coaxially arranged with the sleeve 10a; an interference fit is formed between the outer wall of the copper sleeve 10b and the inner wall of the sleeve 10a; a limiting member 13 is also fixed inside the sleeve 10a, and the two end faces of the copper sleeve 10b are respectively pressed against the corresponding limiting seat 10a2 and the corresponding limiting member 13. This design is used to stably position the copper sleeve 10b inside the sleeve 10a to improve working stability. An annular positioning groove is formed on the inner wall of the sleeve 10a, and the limiting member 13 is a retaining spring installed in the positioning groove.

[0034] like Figure 3 and Figure 4As shown, the guide rod 11 is installed as follows: A connecting plate 14 is vertically fixed to the front side of the support plate 2. There are two connecting plates 14, arranged side by side. The mounting base 9 is located between the two connecting plates 14. Two through holes are provided on the connecting plates 14, respectively facing the two guide rods 11. Both ends of the guide rod 11 are external threaded posts 11a that match the through holes. Each external threaded post 11a is inserted into the corresponding through hole. Each external threaded post 11a is screwed with a pressure cap 15, and the sides of the two connecting plates 14 that are far apart are pressed against the corresponding pressure caps 15. Further, the connecting plates 14 are detachably fixed to the support plate 2 by several bolts; the outer wall of the guide rod 11 is formed with two annular shoulder surfaces 11b, and the shoulder surfaces 11b and the corresponding guide rods 11 are coaxially arranged. Each shoulder surface 11b is located between the two connecting plates 14, and the two shoulder surfaces 11b on the same guide rod 11 are pressed against the two connecting plates 14 respectively, so as to effectively enhance the positioning strength of the guide rod 11. The above design facilitates the disassembly and replacement of the guide sleeve 10.

[0035] The second hydraulic cylinder 12 includes a second cylinder barrel 12a and a second piston rod. The second piston rod is fixedly connected to one of the connecting plates 14, and the second cylinder barrel 12a is fixed to the mounting base 9. In the actual product, the mounting base 9 consists of two connecting blocks arranged side by side. The two connecting blocks are fixedly connected to the left and right sides of the power head 8 by screws. The connecting blocks are vertically arranged, and the above-mentioned mounting holes are provided at both the top and bottom ends of the connecting blocks. Both connecting blocks are provided with support holes for the second cylinder barrel 12a to pass through, and the second cylinder barrel 12a is fixedly connected to both connecting blocks.

[0036] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the limiting member 13 is a retaining ring, and the retaining ring is threadedly connected to the inner wall of the corresponding sleeve 10a.
