Description

Technical Field

[0001] This utility model relates to the field of mining surveying technology, and more specifically, to a portable directional bar for mining surveying. Background Technology

[0002] In underground mine roadway surveying operations, the measurement of horizontal and inclined angles relies on a suspended compass angle measuring instrument. Current industry-standard surveying methods have significant drawbacks: the process requires at least three people working together – one to fix the measurement reference point within the roadway, one to hold the rod to maintain stability, and one to operate the angle measuring instrument and take readings.

[0003] Due to differences in experience and operating habits among different operators, issues such as misalignment of the reference point, tilting of the rod, and misalignment of reading timing are prone to occur, directly leading to reduced accuracy of measurement data and making it difficult to meet the stringent requirements for measurement error in mining operations. At the same time, the multi-person collaborative mode not only significantly increases the workload of on-site workers but also prolongs the overall time spent on preparation and measurement, especially in narrow underground roadways where personnel movement space is limited, further exacerbating the difficulty of coordination, resulting in low measurement efficiency and adversely affecting the continuous progress of mining operations. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a portable directional bar for mining surveying, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a portable directional rod for mining surveying, including a connecting seat, on which a connecting component is provided; The connecting assembly includes a first clamping plate disposed at one end of the connecting seat, a second clamping plate disposed on one side of the first clamping plate, the first clamping plate and the second clamping plate being disposed opposite to each other, and both the first clamping plate and the second clamping plate being rotatably connected to the connecting seat. The first clamping plate and the second clamping plate each have a misalignment groove on their opposite sides. A calibration block is provided in the misalignment groove. The calibration block is rotatably connected to the second clamping plate and the first clamping plate, and a guide groove is provided on the calibration block.

[0006] Optionally, in one possible implementation, a notched clamping tube is fixedly provided at one end of the connecting seat away from the first clamping plate and the second clamping plate. A directional rod is inserted into the notched clamping tube, and a locking sleeve is sleeved on the outside of the notched clamping tube. The locking sleeve is open, and a push rod is threadedly connected to the opening of the locking sleeve. Optionally, in one possible implementation, one end of the top rod is movably connected to a pressure rod, one side of the pressure rod is provided with an arc groove, the arc groove matches the locking sleeve, the pressure rod abuts against the outside of the locking sleeve, and the end of the release rod away from the connecting seat is provided with an extension rod, the extension rod is hinged to the release rod; The technical effects and advantages of this utility model are as follows: The device can be quickly connected and fixed to a fixed structure in the roadway, such as a bracket, using the first clamp, second clamp, and calibration block. No multiple people are needed to hold the rod or align it with the reference. Only one person is required to complete the installation and measurement operation, which completely solves the problem of heavy labor caused by traditional multi-person collaboration.

[0007] The calibration block can be precisely aligned with the guide grooves on the first and second clamping plates to form a unified measurement reference channel, avoiding clamping plate connection deviations; the locking sleeve, top rod, and pressure rod work together to firmly fix the placement rod, preventing the rod from loosening or tilting, thus eliminating measurement errors caused by traditional manual coordination issues from a structural perspective; It can be inserted and removed from the notch clamp; the extension rod can be folded and stored by hinge, reducing the size of the device and making it easy to carry underground; the first clamp and the second clamp can be opened and closed flexibly to adapt to different sizes of fixing structures and are suitable for various roadway measurement scenarios.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This embodiment discloses a portable directional rod for mining surveying, which aims to solve the problems in the prior art where mining surveying requires multiple people to cooperate, and the lack of coordination leads to inaccurate measurements, high labor intensity, and low directional efficiency. By optimizing the overall structural design of the directional rod, it enables convenient operation by a single person, improving measurement accuracy and efficiency.

[0016] Specifically, the portable directional bar for mining surveying includes a connecting base 1, which serves as the core connection base of the entire device, providing a stable mounting and support carrier for each component.

[0017] A connecting assembly is provided on the connecting seat 1 for connecting and fixing with external measurement auxiliary structures, such as fixed brackets in the roadway or temporary support components. The connecting assembly includes a first clamping plate 2 set at one end of the connecting seat 1, and a second clamping plate 3 set parallel to one side of the first clamping plate 2. The first clamping plate 2 and the second clamping plate 3 are distributed in a relative manner, and both are rotatably connected to the connecting seat 1 through a pin. This rotatable connection method allows the first clamping plate 2 and the second clamping plate 3 to open and close flexibly around the pin, which is convenient for adapting to external fixed structures of different sizes and improving the versatility of the device.

[0018] To further improve the stability and fit of the connection, misalignment grooves 4 are provided on the opposite sides of the first clamping plate 2 and the second clamping plate 3. The misalignment grooves 4 prevent structural interference when the first clamping plate 2 and the second clamping plate 3 are closed, and increase the contact area between the clamping plates and the external fixing structure. A guide groove 6 is also provided in the misalignment groove 4, and a calibration block 5 is rotatably connected to the connecting seat 1 at the position between the first clamping plate 2 and the second clamping plate 3. The calibration block 5 also has a guide groove 6 that matches the guide groove 6 in the misalignment groove 4. When the first clamping plate 2 and the second clamping plate 3 are closed to clamp the external fixing structure, the calibration block 5 can be rotated to adjust its angle so that its own guide groove 6 is precisely aligned with the guide grooves 6 on the first clamping plate 2 and the second clamping plate 3, forming a unified guide channel. During subsequent measurements, this guide channel can be used to help determine the measurement reference direction, effectively reducing measurement errors caused by clamping plate connection deviations.

[0019] At the end of the connecting seat 1 away from the first clamping plate 2 and the second clamping plate 3, a notched clamping tube 7 is fixedly installed by welding. The notched clamping tube 7 has a hollow tubular structure and an axial notch on one side of the tube body. This notch design gives the notched clamping tube 7 a certain elastic deformation capability, which facilitates the insertion and removal and fixation of the guide rod 8. The guide rod 8 is inserted into the hollow cavity of the notched clamping tube 7. The guide rod 8 is made of lightweight high-strength alloy material, which not only ensures the structural strength to avoid bending deformation during measurement, but also reduces the weight of the overall device and improves portability. The axial direction of the guide rod 8 is consistent with the center line of the guide groove 6 after alignment with the calibration block 5 and the clamping plate, ensuring the accuracy of the measurement direction.

[0020] To prevent the guide rod 8 from loosening inside the notched clamp tube 7, a locking sleeve 9 is fitted on the outside of the notched clamp tube 7. The locking sleeve 9 is also open, and threaded holes are opened on both sides of its opening. A push rod 10 is threaded into the threaded holes. One end of the push rod 10 extends into the inside of the locking sleeve 9 and is movably connected to a pressure rod 11 through a bearing. The pressure rod 11 has an arc-shaped structure, and an arc groove 12 is opened on the side of the pressure rod 11 facing the notched clamp tube 7. The arc of the arc groove 12 matches the arc of the outer circumference of the locking sleeve 9, so that the pressure rod 11 can tightly abut against the outside of the locking sleeve 9. When it is necessary to fix the directional rod 8, rotate the top rod 10 clockwise. The top rod 10 is pushed into the locking sleeve 9 under the action of the thread, pushing the pressure rod 11 to squeeze the locking sleeve 9. Since the locking sleeve 9 has an opening, its inner diameter is reduced under pressure, thereby tightening the notched clamp tube 7, so that the notched clamp tube 7 firmly clamps the directional rod 8, realizing the stable fixation of the directional rod 8. Conversely, rotating the top rod 10 counterclockwise can loosen the pressure rod 11 and the locking sleeve 9, making it easy to adjust the insertion depth of the directional rod 8 or remove the directional rod 8.

[0021] In addition, an extension rod 13 is hinged to the end of the directional rod 8 away from the connecting seat 1. The material and structural dimensions of the extension rod 13 are the same as those of the directional rod 8. The extension rod 13 can rotate around the hinge point to a position coaxial with the directional rod 8. At this time, the two can be fixedly connected by bolts passing through the pre-set positioning holes on the directional rod 8 and the extension rod 13, thereby extending the length of the entire directional rod to adapt to measurement scenarios of different heights or distances. When extension is not required, the extension rod 13 can be rotated to a position parallel and close to the directional rod 8 to reduce the storage volume of the device and further improve portability.

[0022] The specific working principle is as follows: When conducting surveying operations in mining roadways, firstly, based on the fixed structure within the roadway, such as the support crossbar, rotate the first clamping plate 2 and the second clamping plate 3 to place the fixed structure between the two clamping plates. Then, close the two clamping plates and adjust the calibration block 5 to align the guide grooves 6, completing the connection and fixation between the device and the external fixed structure. Next, insert the directional rod 8 into the notch clamping tube 7. Depending on the required measurement height, choose whether to extend and fix the extension rod 13. Then, rotate the top rod 10, and clamp the directional rod 8 through the cooperation of the pressure rod 11 and the locking sleeve 9. Finally, align the measurement baseline of the suspended compass angle measuring instrument with the calibration block 5 and the aligned guide grooves 6 on the clamping plates. This allows a single person to complete the measurement of horizontal and inclined angles. The entire process requires no multi-person collaboration, avoiding measurement errors caused by poor coordination among personnel. It also simplifies the operation process, shortens the directional time, effectively improves measurement accuracy and efficiency, and the device has a compact structure, making it easy to carry and store, adapting to the complex operating environment of mining sites.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
