Description
Technical Field
[0001] This utility model relates to the field of drilling equipment auxiliary devices, specifically to a drilling operation positioning device. Background Technology
[0002] Ground source heat pump wells are a technical solution that utilizes geothermal energy for heating or cooling. Ground source heat pump wells are usually concentrated in a certain area, so their location needs to be determined in advance to control the spacing between them.
[0003] In traditional techniques, a team of three typically performs the positioning work: two people hold both ends of a measuring tape and tighten it, while the third person inserts the marker rod into the surface soil at the desired location, referring to the markings on the tape. This method requires a large workforce and involves cumbersome procedures, resulting in reduced construction efficiency. Summary of the Invention
[0004] In order to overcome the problem that "the positioning operation of traditional ground source heat pump wells requires a large amount of manpower and the operation steps are complicated, resulting in reduced construction efficiency" in the above-mentioned background technology, this utility model provides a drilling operation positioning device.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a drilling operation positioning device, including a housing detachably connected to the outer wall of the power head, a steel tape measure connected to the housing, and a pointing component installed at the end of the steel tape measure; the outer wall of the power head is provided with a first claw in the shape of a number 7, and the outer wall of the housing is provided with a second claw in the shape of an number L that can be inserted into the first claw from bottom to top; the top surface of the housing is provided with a limiting strip; the limiting strip can be moved laterally, so that the end of the limiting strip moves to directly above the first claw or is removed from directly above the first claw; the steel tape measure is provided with scale lines; and it also includes a marking rod, which can be selectively inserted into the surface soil at different scale line positions.
[0006] As a further optimization of this utility model, the pointing component has a compass at one end near the housing and a vertical hole at the other end away from the housing; it also includes a positioning rod that can be inserted into the vertical hole.
[0007] As a further optimization of this utility model, the first claw is provided with a plurality of claws arranged in a circumferential array with equal spacing and equal angles along the outer side wall of the power head.
[0008] As a further optimization of this utility model, the top surface of the housing is provided with a guide groove, and the limiting strip is placed in the guide groove and can move laterally along the length direction of the guide groove.
[0009] As a further optimization of this utility model, the end of the guide groove points in the direction of the second claw.
[0010] As a further optimization of this utility model, an elastic limiting plate is installed on the top surface of the inner cavity of the housing. The limiting plate includes a straight plate portion and an upper protrusion portion that are fixedly connected to each other. The straight plate portion and the upper protrusion portion are alternately arranged. The top wall of the housing is provided with a receiving hole. The top end of the upper protrusion portion extends out of the receiving hole and selectively engages with a plurality of limiting holes on the bottom surface of the limiting strip.
[0011] As a further optimization of this utility model, the straight plate portion is attached to and fixedly connected to the top surface of the inner cavity of the housing.
[0012] As a further optimization of this utility model, the top surface of the housing is provided with two guide fins, which fasten to the two sides of the limiting strip.

[0014] As a further optimization of this utility model, the pointing component is provided with a receiving cavity for accommodating the steel tape measure, and a spiral spring for driving the steel tape measure to retract is installed in the receiving cavity. The spiral spring is connected to the end of the steel tape measure away from the housing.
[0015] In summary, this utility model has at least one of the following advantages:
[0016] (1) This utility model has a simple structure and reliable function. It uses the power head of the drilling rig as the force point and positioning point of the shell, thereby reducing the need for manpower in positioning operations, simplifying the operation steps, and improving construction efficiency. At the same time, it reduces communication and coordination costs, reduces the probability of errors in manual operation, and improves positioning accuracy.
[0017] (2) The outer wall of the power head is provided with a first claw in the shape of the number 7, and the outer wall of the housing is provided with a second claw in the shape of the number L that can be inserted into the first claw from bottom to top. The gap between the first claw and the outer wall of the power head opens downward, which can prevent dust from falling and accumulating in the gap, and further ensure the smoothness of the second claw when it is inserted into the first claw.
[0018] (3) The top surface of the housing is provided with a limiting strip that can move laterally. When the end of the limiting strip is directly above the first claw, the limiting strip and the second claw clamp the first claw from the upper and lower sides, which can prevent the housing from sliding down under its own weight, thereby stably fixing the housing to the outer wall of the power head.
[0019] (4) Insert the positioning connector into the vertical hole, and then insert the positioning rod into the surface soil to achieve temporary positioning of the pointing component, which can further reduce the need for manpower and realize single-person operation.
[0020] (5) The compass is fixedly installed in the groove on the upper surface of the pointing component. By referring to the direction of the compass and the direction of the steel tape measure, the user can assess the direction of the pointing component relative to the previous drilling position, thus integrating the orientation function.

[0038] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:
[0039] Reference Figures 1-2 This embodiment provides a drilling operation positioning device, including a housing 2 detachably connected to the outer wall of the power head 1, a steel tape measure 3 connected to the housing 2, and a pointing component 4 installed at the end of the steel tape measure 3.
[0040] Reference Figures 1-3 In its stored state, the steel tape measure 3 is coiled into a snail shape and placed inside the pointing assembly 4. In use, the user pulls one end of the steel tape measure 3, removing a portion of it from the pointing assembly 4, thereby measuring the distance between the power head 1 and the pointing assembly 4. The pointing assembly 4 has a receiving cavity for accommodating the steel tape measure 3, and a snail-shaped spring for driving the steel tape measure 3 to retract is installed within the cavity. The spring is connected to the end of the steel tape measure 3 furthest from the housing 2. The spring is a conventional existing technology in the industry, and its specific structure will not be described in detail.
[0041] Reference Figure 1 and Figure 4 The outer wall of the power head 1 is provided with a first 7-shaped chuck 11, the top of which is fixedly connected to the outer wall of the power head 1 (e.g., by bolts). The outer wall of the housing 2 is provided with an L-shaped second chuck 21 that can be inserted into the first chuck 11 from bottom to top, the bottom of which is fixedly connected to the outer wall of the housing 2 (e.g., by bolts). Drilling operations are usually carried out in dusty environments; in this invention, the gap between the first chuck 11 and the outer wall of the power head 1 opens downwards, which can prevent dust from falling and accumulating in the gap, further ensuring the smooth insertion of the second chuck 21 into the first chuck 11.
[0042] Reference Figure 1 and Figure 4 The top surface of the housing 2 is provided with a limiting strip 22; the limiting strip 22 can move laterally, allowing its end to move directly above or away from the first claw 11. When the end of the limiting strip 22 is directly above the first claw 11, the limiting strip 22 and the second claw 21 clamp the first claw 11 from the top and bottom respectively, thus preventing the housing 2 from sliding down under its own weight, thereby stably fixing the housing 2 to the outer wall of the power head 1. After the end of the limiting strip 22 is removed from directly above the first claw 11, the user can grab the housing 2 and drag it downwards, thereby disengaging the first claw 11 and the second claw 21; then the device can be stored away.
[0043] Reference Figure 1 The steel tape measure 3 has graduation lines. This utility model also includes a marking rod 5, which can be selectively inserted into the surface soil at different graduation line positions.
[0044] Reference Figure 2 The pointing component 4 has a compass 41 at one end near the housing 2 and a vertical hole 42 at the other end away from the housing 2. This invention also includes a positioning rod that can be inserted into the vertical hole 42. After the user inserts the positioning rod into the vertical hole 42, it is then inserted longitudinally into the surface soil, temporarily fixing the pointing component 4. This frees up the user's hands to grasp the marking rod 5 and insert it into the desired position, thus enabling single-person operation. This method is more labor-saving than the traditional method, which requires two people to grasp both ends of the measuring tape (ensuring the tape is taut) and a third person to insert the marking rod 5.
[0045] Reference Figure 2 The compass 41 is fixedly mounted in a groove on the upper surface of the pointing assembly 4 by means of an embedded connection (e.g., by bolts). By referring to the direction of the compass 41 and the direction of the (stretched) steel tape measure 3, the user can assess the direction of the pointing assembly 4 relative to the power head 1 (i.e., the previous drilling position).
[0046] The first chuck 11 has several pieces arranged in a circumferential array at equal intervals and angles along the outer wall of the power head 1. For example, if there are four first chucks 11, the included angle between adjacent first chucks 11 is 90 degrees; if there are eight first chucks 11, the included angle between adjacent first chucks 11 is 45 degrees. When drilling needs to be carried out in a certain direction from the previous drilling location, the housing 2 is installed on the first chuck 11 in the corresponding direction. For example, if drilling needs to be carried out in the due east direction from the previous drilling location, the housing 2 is installed on the first chuck 11 in the due east direction.
[0047] Reference Figure 4 and Figure 9 The top surface of the housing 2 is provided with a guide groove, and the limiting strip 22 is placed in the guide groove and can move laterally along the length of the guide groove. The end of the guide groove points in the direction of the second claw 21.
[0048] Reference Figures 5-8An elastic limiting plate 24 (e.g., a stainless steel bent plate) is installed on the top surface of the inner cavity of the housing 2. The limiting plate 24 includes a straight plate portion 241 and an upper protrusion portion 242 that are fixedly connected to each other (e.g., by an integral fixed connection). The straight plate portion 241 and the upper protrusion portion 242 are alternately arranged. The top wall of the housing 2 is provided with a receiving hole 23. The top end of the upper protrusion portion 242 extends out of the receiving hole 23 and selectively engages with a plurality of limiting holes 221 on the bottom surface of the limiting strip 22. A plurality of receiving holes 23 are provided and are evenly spaced along the length direction of the housing 2. A plurality of upper protrusion portions 242 are provided and are respectively inserted into the receiving holes 23. A plurality of limiting holes 221 are provided and are arranged along the length direction of the limiting strip 22. The spacing between adjacent limiting holes 221, the spacing between adjacent upper protrusion portions 242, and the spacing between adjacent receiving holes 23 are adapted to each other.
[0049] Reference Figure 6 and Figure 8 The straight plate 241 is attached to and fixedly connected to the top surface of the inner cavity of the housing 2 (e.g., by a fixed connection).
[0050] Reference Figure 9 The top surface of the housing 2 is provided with two opposing guide fins 25, which are vertically positioned. The cross-section of the guide fins 25 is shaped like the number 7, and the two guide fins 25 are respectively engaged with the two sides of the limiting strip 22. The two guide fins 25 form a strip-shaped guide groove.
[0051] Reference Figure 9 The limiting strip 22 has an upper boss 222 on its top surface, and the upper boss 222 has friction texture 2221 on its top surface. The limiting strip 22 is fixedly connected to the upper boss 222 (e.g., by bolts or by an integral fixed connection). By pressing the friction texture 2221, the user can easily push the limiting strip 22 to move laterally.
[0052] Reference Figure 9 The height of the top surface of the upper boss 222 is higher than the height of the top surface of the guide fin 25. The friction texture 2221 is set on the top surface of the upper boss 222 so that the user can easily contact it.
[0053] Construction steps: ① Perform rotary drilling for the first geothermal heat pump well until the power head 1 of the drilling rig is close to the surface soil (e.g., the distance between the bottom of the power head 1 and the surface soil is no more than 50 cm); ② The operator grasps the housing 2, inserts the second chuck 21 into the first chuck 11 from bottom to top, and then pushes the limiting strip 22 so that the end of the limiting strip 22 is directly above the first chuck 11; ③ Pull the pointing component 4 to move the pointing component 4 away from the power head 1; ④ Insert the positioning connector into the vertical hole 42, and then insert the positioning rod into the surface soil. Inside, the positioning component 4 is temporarily positioned; ⑤ Take several marker rods 5 and selectively insert them into the surface soil at the corresponding positions of different scale lines; ⑥ The personnel remove the positioning rods, grab the positioning component 4 and walk to the vicinity of the housing 2 to retract the steel tape measure 3; ⑦ Push the limiting strip 22 so that the end of the pushing limiting strip 22 is removed from directly above the first claw 11; then grab the housing 2 and move it downward to disengage the first claw 11 and the second claw 21; ⑧ Drilling operation is carried out in the soil layer at the position of the marker rod 5.
[0054] This utility model has a simple structure and reliable function. It uses the power head 1 of the drilling rig as the force point and positioning point of the housing 2, thereby reducing the need for manpower in positioning operations, simplifying operation steps, and improving construction efficiency. At the same time, it reduces communication and coordination costs, lowers the probability of errors in manual operation, and improves positioning accuracy.
[0055] The outer wall of the power head 1 is provided with a first claw 11 in the shape of the number 7, and the outer wall of the housing 2 is provided with a second claw 21 in the shape of the number L, which can be inserted into the first claw 11 from bottom to top. The gap between the first claw 11 and the outer wall of the power head 1 opens downward, which can prevent dust from falling and accumulating in the gap, and further ensure the smoothness of the second claw 21 when it is inserted into the first claw 11.
[0056] The top surface of the housing 2 is provided with a limiting strip 22 that can move laterally. When the end of the limiting strip 22 is directly above the first claw 11, the limiting strip 22 and the second claw 21 clamp the first claw 11 from the upper and lower sides, which can prevent the housing 2 from sliding down under its own weight, thereby stably fixing the housing 2 to the outer wall of the power head 1.
[0057] The positioning connector is inserted into the vertical hole 42, and then the positioning rod is inserted into the surface soil to achieve temporary positioning of the pointing component 4, which can further reduce the need for manpower and enable single-person operation.
[0058] The compass 41 is fixedly installed in a groove on the upper surface of the pointing component 4. By referring to the direction of the compass 41 and the direction of the steel tape measure 3, the user can assess the direction of the pointing component 4 relative to the previous drilling position, thus integrating the orientation function.
[0059] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0060] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
