Description

Technical Field

[0001] The present invention relates to the technical field of laser measurement, in particular to a vertical shaft construction measurement device. Background Art

[0002] Coal mine shafts are the only way to connect underground resource extraction and surface production systems. They also bear the heavy responsibility of mining safety. Regular deformation detection of shafts and tankways is of great significance to the safe operation of shaft lifting containers and the safe and efficient production of coal mines. At present, the main methods for providing a unified measurement benchmark within the entire shaft range are: wire plumb line method, laser plumb line method, etc. The laser plumb line method is a shaft deformation monitoring technology based on the principle of laser alignment. By establishing a high-precision laser reference line, the offset of the characteristic points of the shaft wall relative to the reference is measured to analyze the overall deformation of the shaft. Its core is to use a laser plumb line to project a plumb beam as a measurement reference. Compared with the traditional wire plumb line method, it has the characteristics of high precision, strong anti-interference, and efficient operation. It has become the mainstream technology for modern vertical shaft measurement.

[0003] When using a laser plumb line, a tripod needs to be set up near the wellhead, and the laser plumb line needs to be installed on the supporting platform. The leveling knob and the long level are used to ensure that the instrument is level. Then the laser is directed to the pre-buried steel plate marking point or laser target at the bottom of the well. The underground personnel mark the laser position with a marker or a photoelectric recorder, and then rotate the instrument clockwise 90 degrees, 180 degrees, and 270 degrees in turn. The laser position is recorded after each rotation, and then the diagonal laser position is connected. The intersection of the two lines is the theoretical plumb reference point. Finally, the deflection fine-tuning screws of the instrument base or optical path system are adjusted (usually three sets of orthogonal screws) to make the light spot coincide with the reference point. This is a key step to ensure that the laser optical axis and the sighting axis are strictly coaxial. In vertical well construction, the verticality error of the wellbore needs to be controlled within 1 / 8000 of the well depth. Therefore, the coaxial calibration of the optical axis and the sighting axis can ensure that the initial reference of the laser beam is not offset, avoid error accumulation, and ensure measurement accuracy.

[0004] However, in actual operation, the rotation of the traditional plumb line relies on a manual dial, and it is difficult for the operator to accurately locate the theoretical angle. In addition, when rotating and recording, slight rebound may occur due to its own weight or vibration, and the actual angle deviates from the set value, resulting in the destruction of the symmetry of the quadrilateral formed by the four light spots. The vertical deviation of the wellbore directly affects the safe operation of the lifting container. If the reference is offset due to rotation error, it may cause the tankway to be stuck or even a tank falling accident, increasing the risk of subsequent construction. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When performing laser measurement, turn on the laser plummet, adjust the focusing handwheel to focus the light spot, and direct the laser to the pre-buried steel plate marking point or laser target at the bottom of the well. The underground personnel mark the laser position with a marker or photoelectric recorder, and record the current laser position as P1. Then start rotating the laser plummet at multiple angles. Through the cooperation of the pointer and the dial, rotate it 90 degrees, 180 degrees, and 270 degrees in sequence. Record the laser position after each rotation to form four points P1, P2, P3, and P4. Then connect the diagonal laser positions, and the intersection of the two lines is the theoretical plumb reference point. Finally, adjust the adjustment knob on the instrument base to make the light spot coincide with the reference point to complete the laser calibration. Then, the distance between the laser and the inner wall of the wellbore at different positions can be measured to obtain the wellbore deformation data.

[0020] 2. When calibrating the laser plummet, the trigger block and the trigger tooth cooperate to achieve stepped vibration sensing as the instrument approaches each laser position. This allows the operator to quickly sense the critical rotation angle through visual and tactile sensations, discretizing the continuous rotation operation into graduated calibration, forcing the operator to confirm the position degree by degree, avoiding errors caused by visual fatigue or dust obstruction when manually observing the dial. This is particularly suitable for dusty or dim environments during construction. After rotating to the required angle, it can be fixed by a spring, making it easy to record and determine the current laser position, which is beneficial to ensuring the laser measurement accuracy of this device.

[0021] 3. When calibrating the laser plummet, the resistance block and the slide bar cooperate to gradually increase the rotational friction as the device approaches each laser position, forming a tactile resistance gradient. The sudden increase in resistance prompts the operator to slow down, and assists the operator in making fine adjustments at critical moments. At the same time, no resistance contact is made when the angle difference is large, ensuring adjustment efficiency and thus facilitating the laser measurement accuracy of the device.

[0022] 4. When calibrating the laser plummet, the locking rod cooperates with connecting slot 1 so that when it is precisely rotated to the required angle, gravity causes the locking rod to fall into connecting slot 1, locking it. This prevents slight movement of the current laser position due to accidental touch or vibration during the recording process, ensuring the accuracy of the laser position. At the same time, the connecting rod cooperates with magnetic blocks 1 and 2, so the operator only needs to press with one hand and rotate with the other hand to unlock it. The two-hand unlocking design enforces compliance with safety operating regulations and reduces the risk of misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] For example 1, please refer to Figure 1-Figure 7 The present invention provides a vertical shaft construction measurement device, including a laser plummet body 1, a chassis 2, a scale plate 4, a pointer 5, a laser plummet 6, a base 10, and an adjustment knob 11. The bottom of the retaining ring 3 is fixedly mounted on the top of the scale plate 4, and the top of the retaining ring 3 is rotatably connected to the bottom of the chassis 2.

[0033] The inner wall of the retaining ring 3 is provided with a graduated retaining component 7;

[0034] Furthermore, the indexing retaining component 7 includes a slide bar 701, and the top of the slide bar 701 is fixedly connected to the bottom of the chassis 2, the bottom of the slide bar 701 is slidably connected to the top of the scale plate 4, the outer wall of the slide bar 701 away from the laser plummet 6 is fixedly connected to a shell 702, and the outer wall of the shell 702 away from the slide bar 701 is provided with a groove 703, the inner wall of the groove 703 is fixedly connected to a spring 1 704, and the end of the spring 1 704 away from the slide bar 701 is fixedly connected to a trigger block 705, and the inner wall of the retaining ring 3 is fixedly connected to a trigger tooth 706 at an equal distance corresponding to the trigger block 705;

[0035] More specifically, in this embodiment, when using the measuring device, a tripod is first set up near the wellhead, and the laser plummet main body 1 is installed on the tripod to ensure that the base is stable. The tripod height is then adjusted so that the telescope eyepiece of the laser plummet main body 1 is level with the human eye. The laser plummet 6 is then turned on, and the focusing hand wheel is adjusted to focus the light spot. The laser is then directed to the pre-embedded steel plate marking point or laser target at the bottom of the well. The underground personnel mark the laser position with a marker pen or a photoelectric recorder, and the current laser position is recorded as P1.

[0036] Then, the laser plummet 6 is rotated at multiple angles. Through the cooperation of the pointer 5 and the scale plate 4, it is rotated 90 degrees, 180 degrees, and 270 degrees in sequence. The laser position is recorded after each rotation to form four points: P1, P2, P3, and P4. Then, the diagonal laser positions are connected, and the intersection of the two lines is the theoretical plumb reference point. Finally, the adjustment knob 11 of the instrument base 10 is adjusted to make the light spot coincide with the reference point to complete the laser calibration. Then, the distance between the laser and the inner wall of the wellbore at different positions can be measured to obtain the wellbore deformation data.

[0037] Then, during the rotation process, the top of the slide bar 701 is fixedly connected to the bottom of the chassis 2, and the bottom of the slide bar 701 is slidably connected to the top of the scale plate 4, so that when the rotating chassis 2 drives the laser plummet 6 to rotate, the slide bar 701 will be synchronously driven to move in a circle. Then, the outer wall of the slide bar 701 away from the laser plummet 6 is fixedly connected to the shell 702, and the outer wall of the shell 702 away from the slide bar 701 is provided with a groove 703, and the inner wall of the groove 703 is fixedly connected to a spring 70 4, and the end of the spring 1 704 away from the slide rod 701 is fixedly connected to a trigger block 705, and the inner wall of the retaining ring 3 is fixedly connected to the trigger block 705 at an equal distance. The trigger teeth 706 are in four groups, which are the same as the fixed distance of rotating ninety degrees. That is, moving from the middle tooth groove of one group of trigger teeth 706 to the middle tooth groove of another group of trigger teeth 706 is regarded as rotating ninety degrees, and the front and rear tooth grooves of the middle tooth groove of each group of trigger teeth 706 have a difference of five degrees or ten degrees, or other degrees that can divide ninety degrees.

[0038] As the trigger block 705 rotates to approach each laser position, it will contact the trigger teeth 706 through the drive of the slide bar 701. When the rotation continues, the trigger block 705 will retract into the groove 703 under the contact of the trigger teeth 706. When it moves a distance that is divisible by ninety degrees, such as five or ten degrees, it will re-extend and engage the two adjacent trigger teeth 706 under the drive of the spring 1 704. When approaching the target laser position, step-by-step vibration sensing is achieved, allowing the operator to quickly sense the critical rotation angle by visually observing the pointer 5 and the dial 4 and by tactile sensation, discretizing the continuous rotation operation into graduated calibration, forcing the operator to confirm the position degree by degree, avoiding errors caused by visual fatigue or dust obstruction when manually observing the dial 4. This is particularly suitable for dusty or dim environments during construction. After rotating to the required angle, that is, when it is screwed into the middle tooth groove of each set of trigger teeth 706, it can be fixed by the spring 1 704, facilitating the recording and determination of the current laser position, which is conducive to ensuring the laser measurement accuracy of the device.

[0039] Embodiment 2: Based on the above embodiment, resistance adapting components 8 are provided at equal distances on the top of the scale plate 4;

[0040] Furthermore, the resistance-range adapter component 8 includes a mounting plate 801, the bottoms of the four mounting plates 801 are fixedly connected to the top of the scale plate 4 at equal distances, the outer walls of the four mounting plates 801 on the side away from each other are symmetrically fixedly connected with spring 2 802, and the other end of the spring 2 802 is fixedly connected with a resistance block 803, the outer wall of the resistance block 803 on the side away from the mounting plate 801 is inclined corresponding to the slide bar 701, the outer walls of the four mounting plates 801 on the side away from each other are fixedly connected with a slider 804, the outer walls of the four resistance blocks 803 on the side close to each other are provided with a sliding groove 805 corresponding to the slider 804, and the outer wall of the slider 804 is slidably connected to the inner wall of the sliding groove 805;

[0041] More specifically, in the present embodiment, in the process of rotating close to each laser position, the outer wall of one side of the four mounting plates 801 away from each other is symmetrically fixedly connected to the spring 2 802, and the other end of the spring 2 802 is fixedly connected to the resistance block 803, and the outer wall of the side of the resistance block 803 away from the mounting plate 801 is inclined corresponding to the slide bar 701, so that when rotating close to each laser position, the resistance block 803 driven by the spring 2 802 can contact the slide bar 701, and as the slide bar 701 continues to rotate, the resistance block 803 will continuously increase the compression of the spring 2 802 by the inclined surface, thereby gradually increasing the rotational friction force, forming a hand-feel resistance gradient, and the sudden increase in resistance prompts the operator to slow down, and by forced deceleration, the operator can be assisted to better perform fine adjustment at the critical laser position, and at the same time, no resistance contact is performed when the angle difference is large, thereby ensuring the adjustment efficiency, which is conducive to ensuring the laser measurement accuracy of the present device;

[0042] Then, a slider 804 is fixedly connected to the outer wall of the four mounting plates 801 on the side away from each other, and a sliding groove 805 is opened on the outer wall of the four resistance blocks 803 on the side close to each other, corresponding to the slider 804. The outer wall of the slider 804 is slidably connected to the inner wall of the sliding groove 805, so that the stability of the resistance blocks 803 during telescopic movement can be ensured by the cooperation between the slider 804 and the sliding groove 805.

[0043] Then, the roller 707 is connected to the outer wall of the sliding rod 701 away from the shell 702 at an equal distance from the resistance adapter component 8, thereby reducing the wear between the sliding rod 701 and the resistance block 803 and improving the service life.

[0044] Embodiment 3: Based on the above embodiment, locking and anti-error components 9 are provided at equal distances inside the dial 4;

[0045] Furthermore, the locking anti-error component 9 includes a locking rod 901, and the locking rod 901 is arranged inside the sliding rod 701. A receiving groove 902 is opened through the top of the sliding rod 701, and the outer wall of the locking rod 901 fits and slides with the inner wall of the receiving groove 902. A connecting groove 1 903 is opened at an equal distance on the top of the dial 4 corresponding to the locking rod 901, and the outer wall of the locking rod 901 fits and slides with the inner wall of the connecting groove 1 903. A connecting groove 2 904 is opened at an equal distance on the outer wall of the dial 4, and the inner wall of the connecting groove 2 904 is connected to the inner wall of the connecting groove 1 903. The inner wall of the connecting groove 2 904 fits and slides with a connecting rod 905.

[0046] More specifically, in this embodiment, when the desired angle is precisely rotated, the locking rod 901 is arranged inside the sliding rod 701, and a receiving groove 902 is formed through the top of the sliding rod 701, and the outer wall of the locking rod 901 is fitted and slid with the inner wall of the receiving groove 902, and the top of the scale plate 4 is provided with a connecting groove 1 903 at an equal distance corresponding to the locking rod 901, and the outer wall of the locking rod 901 is slidably matched with the inner wall of the connecting groove 1 903, so that the locking rod 901 can fall into the connecting groove 1 903 by gravity and be locked, thereby avoiding slight movement of the current laser position due to accidental touch or vibration during the recording process, thereby ensuring the accuracy of the laser position;

[0047] Then, when the recording is completed and it needs to be rotated to the next laser position, a second connecting groove 904 is opened at equal distances through the outer wall of the scale plate 4, and the inner wall of the second connecting groove 904 is connected to the inner wall of the first connecting groove 903, and the inner wall of the second connecting groove 904 is slidably connected to a connecting rod 905, and the end of the four connecting rods 905 is fixedly connected to a magnetic block 1 906, and the bottom of the locking rod 901 is fixedly connected to a magnetic block 2 907 corresponding to the magnetic block 1 906, so that the connecting rod 905 can be pressed by one hand to move the magnetic block 1 906 to the bottom of the magnetic block 2 907, and the locking rod 901 is raised and reset again in a mutually exclusive manner. At this time, the other hand can synchronously rotate the chassis 2 to unlock it, so that the operator needs to press with one hand and rotate with the other hand to unlock it. The two-hand unlocking design is adopted to enforce compliance with safety operation specifications and reduce the risk of misoperation.

[0048] Then, a fixing ring 908 is fixedly connected to the outer wall of the distal end of the four connecting rods 905, and a spring 3 909 is provided on the outer wall of the connecting rod 905. The distal end of the four springs 3 909 is fixedly connected to the proximal end surface of the four fixing rings 908, and the proximal end of the four springs 3 909 is fixedly connected to the outer wall of the scale plate 4. Therefore, under normal circumstances, the spring 3 909 controls the connecting rod 905 to reset, preventing the connecting rod 905 from being in an abnormal position, which would cause the locking rod 901 to fail to fall normally.

[0049] Then, a limiting groove 910 is symmetrically opened on the inner wall of the storage groove 902, and the outer wall of the locking rod 901 is symmetrically fixedly connected to the limiting block 911, and the outer wall of the limiting block 911 slides in contact with the inner wall of the limiting groove 910, so that the falling position of the locking rod 901 can be limited by the cooperation between the limiting block 911 and the limiting groove 910 to avoid complete detachment.

[0050] Working principle: When using this measuring device, first set up a tripod near the wellhead and install the laser plummet body 1 on the tripod. Turn on the laser plummet 6, adjust the focusing hand wheel to focus the light spot, and direct the laser directly to the pre-buried steel plate marking point or laser target at the bottom of the well. Then start to rotate the laser plummet 6 at multiple angles. When the rotating chassis 2 drives the laser plummet 6 to rotate, it will synchronously drive the slide bar 701 to move in a circle.

[0051] During the process of rotating to approach each laser position, the trigger block 705 will contact the trigger teeth 706 through the drive of the slide bar 701. At this time, when the rotation continues, the trigger block 705 will retract into the groove 703 under the contact of the trigger teeth 706. When it moves a distance that is divisible by ninety degrees, such as five or ten degrees, it will re-extend and snap into two adjacent trigger teeth 706 under the drive of the spring 1 704. When approaching the target laser position, step-by-step vibration sensing is achieved, so that the operator can quickly sense the critical rotation angle by visually observing the pointer 5 and the dial 4 and by tactile sense, discretizing the continuous rotation operation into graduated calibration, forcing the operator to confirm the position degree by degree, avoiding errors caused by visual fatigue or dust obstruction when manually observing the dial 4. It is particularly suitable for dusty or dim environments during construction. After rotating to the required angle, that is, when it is screwed into the middle tooth groove of each set of trigger teeth 706, it can be fixed by the spring 1 704, which facilitates the recording and determination of the current laser position, which is conducive to ensuring the laser measurement accuracy of the device.

[0052] When the rotation approaches each laser position, the resistance block 803 driven by the second spring 802 can contact the slide bar 701, and as the slide bar 701 continues to rotate, the inclined surface of the resistance block 803 is used to make the resistance block 803 continuously increase the compression of the second spring 802, thereby correspondingly gradually increasing the rotational friction, forming a hand-feel resistance gradient. The sudden increase in resistance prompts the operator to slow down, and by forced deceleration, it can assist the operator to better perform fine adjustments at critical laser positions. At the same time, when the phase angle difference is large, no resistance contact is made, thereby ensuring adjustment efficiency, which is conducive to ensuring the laser measurement accuracy of the device;

[0053] When it is precisely rotated to the required angle, gravity can cause the locking rod 901 to fall into the connecting slot 1 903 to achieve locking, avoiding slight movement of the current laser position due to accidental touch or vibration during the recording process, thereby ensuring the accuracy of the laser position. At the same time, when the recording is completed and it needs to be rotated to the next laser position, one hand presses the connecting rod 905 to move the magnetic block 1 906 to the bottom of the magnetic block 2 907, and the locking rod 901 rises and resets again in a mutually exclusive manner. At this time, the other hand synchronously rotates the chassis 2 to unlock it, so that the operator needs to press with one hand and rotate with the other hand to unlock it. The two-hand unlocking design is adopted to enforce compliance with safety operating specifications and reduce the risk of misoperation.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
