Description

Technical Field

[0001] This utility model relates to the field of drilling rig auxiliary equipment, and in particular to a hydrological borehole drilling rig attitude orientation calibration device. Background Technology

[0002] Hydrological drilling rigs are large industrial equipment, generally consisting of a self-propelled unit and a portable drilling unit. When traveling to the drilling position, in order to ensure that the drilling unit can be driven vertically into the ground, hydraulic support components are usually installed on its chassis to achieve a horizontal vehicle body, so that the drilling rig is in a vertical position.

[0003] However, this method of drilling often results in some deviation in verticality. This is due to various reasons, such as inaccurate hydraulic support leveling, especially on soft ground. Even with the aid of sleepers or other blocks, it's impossible to achieve a level vehicle body, leading to drill rod tilting. To ensure the drill rod is vertical or drills into the ground within a certain tolerance, repeated leveling and calibration are necessary. The lack of appropriate auxiliary equipment further complicates the process. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hydrological drilling rig attitude orientation calibration device with a simple structure that is mounted on a hydrological drilling rig and uses the constraint of the drill rod attitude as a means to control the drill rod entry angle into the soil within the tolerance range.

[0005] The equipment includes assembly components, which are fixedly mounted on the front of the drilling rig's housing;

[0006] An assembly body is provided in front of the aforementioned assembly component; the assembly body is the basic component of this equipment.

[0007] The assembly is provided with a support rod, and a positioning plate is provided on the top surface of the support rod;

[0008] A ball-head sliding sleeve is provided in the center of the positioning plate.

[0009] A ball head is rotatably disposed within the ball head sleeve. A through channel with the center of the ball as the midpoint is provided on the ball head, and the channel extends from the edge of the channel. Constraint sleeves are respectively provided at both ends of the channel.

[0010] Furthermore, a hard limiting bolt is provided on the ball head sliding sleeve. That is, the hard limiting bolt presses against the outer wall of the ball head to limit its position.

[0011] The effect achieved is that, based on the rotation setting of the ball head and the counterweight of the constraint sleeve, the ball head part is naturally horizontal without external force interference; that is, after the drilling rig is leveled, the drill rod can pass through the through channel of the ball head normally, so the drill rod is vertical or drills into the ground within tolerance, thus achieving the effect of auxiliary calibration.

[0012] The beneficial effects of this utility model are: This utility model solves the problem of difficult drill rod calibration in the prior art. It is assembled on the drilling rig in the form of an external connection, and realizes auxiliary calibration based on actual working conditions when the drill rod is lowered, which optimizes the calibration operation process and makes it easier to control the verticality of the drill rod.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 The present invention provides a hydrological drilling rig attitude orientation calibration device, which includes an assembly component, and the assembly component is fixedly installed in front of the drilling rig housing.

[0018] An assembly body is provided in front of the aforementioned assembly component; the assembly body is the basic component of this equipment.

[0019] The assembly is provided with a support rod, and a positioning plate is provided on the top surface of the support rod;

[0020] A ball-head sliding sleeve 8 is provided in the center of the positioning plate.

[0021] A ball head 6 is rotatably disposed within the ball head sliding sleeve 8. A through channel with the center of the ball as the midpoint is provided on the ball head 6, and the channel extends from the edge of the channel. A constraint sleeve 7 is provided at both ends of the channel.

[0022] Preferably, the constraint sleeve 7 is configured to penetrate the channel on the ball head 6, and their inner diameters are the same.

[0023] Furthermore, a hard limiting bolt 5 is provided on the ball head sliding sleeve 8. That is, the hard limiting bolt 5 presses against the outer wall of the ball head 6 to limit its position.

[0024] The effect achieved is that, based on the rotation setting of the ball head 6 and the counterweight of the constraint sleeve 7, the ball head 6 is naturally horizontal without external force interference; that is, after the drilling rig is leveled, the drill rod can pass through the through channel of the ball head 6 normally, so the drill rod is vertical or drills into the ground within tolerance, thereby achieving the effect of auxiliary calibration.

[0025] Furthermore, the assembly component is flange 1.

[0026] This achieves the effect that the equipment can be stably mounted on the drilling rig housing.

[0027] Furthermore, the assembly includes a connecting part 2 and a supporting body 3. The connecting part 2 is integrally connected to the assembly components; the supporting body 3 is integrally connected to the connecting part 2, and the connection part 2 to the supporting body 3 is a round-to-square transition setting.

[0028] This achieves the effect of further improving the stability of the relevant equipment.

[0029] Example 1, refer to the accompanying drawings in the specification. Figure 1 There are a total of four support rods, and the four support rods are divided into two groups of two. Each group of support rods includes a guide rod 9 and a telescopic rod 4.

[0030] The assembly has assembly wing plates 10 on its sides, and two sets of support rods are arranged symmetrically on the assembly wing plates 10 on both sides of the assembly; the telescopic rod 4 is fixed. The guide rod 9 is either fixed or slidable.

[0031] The effect achieved is that the height of the positioning plate is adjustable, and it always maintains a horizontal displacement with respect to the assembly, relying on the support rod. During use, the adjustable positioning plate does not affect the sequential connection of the drill rod, and it can continuously calibrate whether the newly connected drill rod is skewed during continuous operation.

[0032] Example 2. The telescopic rod 4 is a hydraulic rod.

[0033] In Example 3, a secondary guide sleeve for the drill pipe is centrally located within the assembly.

[0034] The effect achieved in this way is to assist in constraining the drill pipe.

[0035] In Example 4, the inner diameters of both the secondary guide sleeve and the constraint sleeve 7 are larger than those of the drill pipe. "Slightly larger" here means slightly larger; this allows for a certain degree of inclination in the drill pipe angle within tolerance, thus preventing hard friction between the drill pipe and the equipment.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
