Description

Technical Field

[0001] The utility model relates to the technical field of inclinometers, in particular to an inclinometer fixing bracket. Background Art

[0002] A gyro inclinometer is a device used to determine the azimuth of borehole inclination. It is a general term for inclinometers that use gyro elements to determine the azimuth of borehole inclination. The azimuth measured by this gyro inclinometer is relative. Before the instrument goes down into the borehole, it is necessary to determine a direction on the ground and then start the mechanical gyro, which is mounted on a universal frame with three degrees of freedom to allow it to reach a stable high-speed rotation state. At this time, the gyro has directional properties. When measuring downhole, the rotation of the instrument and the deflection of the borehole inclination direction cannot change the starting direction of the gyro rotor under ideal conditions. By measuring and recording the angle that the instrument rotates relative to the starting direction, the inclination of the borehole can be calculated. Obviously, the inclination of the borehole is calculated from the starting direction of the gyro, and the measurement result is called relative azimuth.

[0003] During the freeze drilling process, the gyro inclinometer is usually lowered every 20-30m to measure the inclination. The inclinometer data is used to guide the drilling rig to continue drilling according to the designed target area. The premise of frequent inclinometer measurement is that the gyro must be fixed in the drill pipe on the drilling rig's grinding disc before each instrument is lowered, and the azimuth is adjusted using the theodolite and the point on the center line of the wellbore, and then the gyro is lowered for inclinometer measurement. During the azimuth adjustment process, the gyro inclinometer needs to be placed still in the drill pipe of the grinding disc. After the direction adjustment is completed, the gyro is lifted up and placed in the borehole, and then slowly lowered along with the guide wheel. Since the drilling rig grinding disc is 1.0m above the ground, and the auxiliary accessories and guide wheels are 1.2-1.5m high, the entire inclinometer is about 2.0m long, wrapped in stainless steel casing, and weighs about 20kg. It needs to be in place before debugging (temporarily stuck in the drill pipe mouth), and the entire buckle needs to be removed after debugging, which is time-consuming and labor-intensive, and the operation is not easy. It affects the direction of the logging instrument during use, resulting in errors in the azimuth of the inclinometer data. Therefore, it is urgent to solve this problem.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Example

[0027] See also Figures 1-3 As shown:

[0028] The utility model provides an inclinometer fixing bracket, comprising: an inclinometer A to be fixed, a drill rod B, a first supporting plate 11, a second supporting plate 12 and a fixing and adjusting component.

[0029] One end of the first support plate 11 and the second support plate 12 are hinged with the fixed adjustment assembly, and the first support plate 11 and the second support plate 12 are both horizontally placed on the top of the drill rod B. One end of the inclinometer A to be fixed passes through the gap between the first support plate 11 and the second support plate 12, and is plugged with the top of the drill rod B, and is clamped with the first support plate 11 and the second support plate 12 that are close to each other.

[0030] In specific applications, since the end of the inclinometer A to be fixed and the drill pipe B form an inserted end and are not wrapped by a stainless steel sleeve, a region where the first support plate 11 and the second support plate 12 can be clamped after being closed to each other is formed at the end of the inclinometer A to be fixed. The upper surfaces of the first support plate 11 and the second support plate 12 horizontally placed on the top of the drill pipe B stably support the stainless steel sleeve end of the inclinometer A to be fixed, and the first support plate 11 and the second support plate 12 are simultaneously clamped with the top end of the drill pipe B, so that the entire inclinometer A to be fixed is not easy to shake, improving the stability when the inclinometer A to be fixed automatically adjusts the direction, and improving the accuracy of the subsequent measurement of the drilling angle by the inclinometer A to be fixed.

[0031] The fixing and adjusting assembly includes a connecting part and a locking part; the connecting part is hinged to the ends of the first support plate 11 and the second support plate 12; the locking part is arranged at the hinge joint of the connecting part and the ends of the first support plate 11 and the second support plate 12 for locking the first support plate 11 and the second support plate 12 on the connecting part.

[0032] By providing the locking part and the connecting part, the first support plate 11 and the second support plate 12 are convenient to open or close during actual use, facilitating the operation of the operator and improving the convenience of using the entire fixing bracket.

[0033] The connecting part includes a U-shaped clamping plate 21; the U-shaped clamping plate 21 is sleeved on one end of the first support plate 11 and the second support plate 12, and hinge shafts are provided at both ends of the U-shaped clamping plate 21, and the two hinge shafts respectively pass through the first support plate 11 and the second support plate 12. In order to facilitate the first support plate 11 and the second support plate 12 not to interfere with each other when closing or opening, the connection parts of the first support plate 11 and the second support plate 12 with the two hinge shafts are both set to be arc-shaped, and at the same time, a contact block is arranged on the U-shaped clamping plate 21. After the first support plate 11 and the second support plate 12 are closed to each other, the ends of the first support plate 11 and the second support plate 12 located in the U-shaped clamping plate 21 can both form contact with the contact block, and the locking part is arranged on the hinge shaft. This makes the connection between the first support plate 11 and the second support plate 12 and the U-shaped clamping plate 21 closer after being locked by the locking part, so that when the inclinometer A to be fixed automatically adjusts the direction, the entire fixing bracket is not easy to shake between components, making the entire fixing bracket have better support for the inclinometer A to be fixed.

[0034] For the convenience of the operator to use, the locking part is set as a manual fastening nut 22. The manual fastening nut 22 is threadedly connected to the end of the hinge shaft. Further, the hinge shaft is set as a bolt, so that by rotating the manual fastening nut 22, the first support plate 11, the second support plate 12 and the U-shaped clamping plate 21 are locked to each other, so that when the inclinometer A to be fixed automatically adjusts the direction, it is not easy to shake.

[0035] In addition, when the first support plate 11 and the second support plate 12 form a clamping connection with the ends of the inclinometer A and the drill pipe B to be fixed, after locking by manually tightening the nut 22, the clamping connection between the entire fixing bracket and the inclinometer A and the drill pipe B to be fixed is more stable.

[0036] The first support plate 11 and the second support plate 12 are both provided with L-shaped notches on their sides, and the two L-shaped notches together form a clamping interface 13 that forms a clamping connection with the end of the inclinometer A to be fixed. In specific applications, the clamping interface 13 is set to be rectangular or trapezoidal.

[0037] When the clamping interface 13 is trapezoidal, the entire fixing bracket can form a clamping connection with the inclinometer A and the drill pipe B to be fixed with different diameters. Of course, in specific use, when the inclinometer A and the drill pipe B to be fixed with different diameters are used in combination, their diameter ratios increase regularly, so that the fixing bracket can be applied to more usage scenarios.

[0038] In order to better clamp the drill pipe B, a first clamping strip 111 is provided at the bottom of the first support plate 11; a second clamping strip 121 is provided at the bottom of the second support plate 12. In specific use, the first clamping strip 111 and the second clamping strip 121 are respectively located on both sides of the clamping interface 13 and are parallel to both sides of the clamping interface 13, and the distance between the first clamping strip 111 and the second clamping strip 121 is the same as the outer diameter of the drill pipe B, so as to be able to form a clamping connection with the outside of the top of the drill pipe B.

[0039] When the entire clamping interface 13 is trapezoidally distributed, the variation law of the distance between the first clamping strip 111 and the second clamping strip 121 is the same as the law of proportional increase in diameter when the inclinometer A and the drill pipe B to be fixed with different diameters are used in combination. Thus, while the entire fixing bracket clamps the drill pipe B, it can also form a clamping connection with the end of the inclinometer A to be fixed. This enables the entire fixing bracket to be applicable to different models of the inclinometer A and the drill pipe B to be fixed, making the application of the entire fixing bracket more extensive.

[0040] It further includes a handle 23; the handle 23 is connected to the U-shaped clamping plate 21. In specific use, the handle 23 is set to be U-shaped, so as to facilitate the operator to pick up the entire fixing bracket.

[0041] It should be noted that if there are directional indications involved in the embodiments of the present utility model, such as up, down, left, right, front, back..., then the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture as shown in the attached drawings. If the specific posture changes, the directional indications will also change accordingly. In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, "a plurality of" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.
