Description

Technical Field

[0001] This invention relates to the field of measuring instruments, and in particular to a device for measuring the slope of high-altitude pipelines. Background Technology

[0002] With the increasing number of large-scale industrial buildings in my country, the installation of electromechanical pipelines at heights is becoming more and more common. Various types of electromechanical pipelines have different slope requirements. Slope measurement of pipelines is one of the core inspection items for pipeline installation and also one of the key points for quality control of electromechanical pipeline installation.

[0003] The usual practice is to first visually determine whether the pipeline installation has a slope, then measure the elevation at both ends of the pipeline and the pipeline length, and then calculate the pipeline slope. This method of measurement is relatively cumbersome, requires a high level of measurement skills from workers, is time-consuming, and cannot intuitively display the pipeline slope. Summary of the Invention

[0004] To address the aforementioned problems, embodiments of the present invention provide a high-altitude pipeline slope measurement device.

[0005] The high-altitude pipeline slope measuring device of the present invention includes: two vertical telescopic hanging rods, each with a clamping mechanism at its top, and the vertical telescopic hanging rods being connected to the pipeline under test via the clamping mechanisms; a horizontal telescopic test rod, the two ends of which are rotatably connected to the bottoms of the two vertical telescopic hanging rods, forming a four-bar linkage between the horizontal telescopic test rod, the vertical telescopic hanging rods, and the pipeline under test; a dial, connected to the horizontal telescopic test rod via a collar, and capable of rotating relative to the vertical telescopic hanging rods with the horizontal telescopic test rod; and a pointer, located at the bottom of one of the vertical telescopic hanging rods, inside the dial, and equipped with a counterweight.

[0006] Optionally, the vertical telescopic hanging rod includes a first vertical hanging rod and a second vertical hanging rod. The bottom of the first vertical hanging rod is provided with a fixed connecting rod, which is perpendicular to the first vertical hanging rod. A collar and a dial are sleeved on the fixed connecting rod. The collar and the dial are fixedly connected, and both the collar and the dial are rotatably connected to the fixed connecting rod. The collar is detachably connected to the horizontal telescopic test rod.

[0007] Optionally, the dial also includes a display disk and a convex lens. The display disk is located on the side closer to the collar and has a scale at its lower part. The convex lens is located on the side away from the collar and corresponds to the scale on the display disk. The pointer is mounted on a fixed connecting rod via a bearing and is located between the display disk and the convex lens.

[0008] Optionally, the second vertical hanging rod and the horizontal telescopic test rod are connected by a double-headed ball pin. Both ends of the double-headed ball pin are provided with limit rings. The second vertical hanging rod and the horizontal telescopic test rod are provided with locking mechanisms at the connection position. The locking mechanisms are detachably connected to the double-headed ball pin.

[0009] Optionally, the tops of both the first and second vertical hanging rods are connected to the clamping mechanism via a locking mechanism and a ball pin, with a limiting ring on the ball pin.

[0010] Optionally, the locking mechanism is located inside the first vertical hanging rod, the second vertical hanging rod, and the horizontal telescopic test rod. The locking mechanism is connected to one end of the locking switch, and the other end of the locking switch passes through the first vertical hanging rod, the second vertical hanging rod, and the horizontal telescopic test rod, respectively.

[0011] Optionally, the locking mechanism includes two rotating rods hinged to the locking switch. The rotating rods are L-shaped and are located inside the first vertical hanging rod, the second vertical hanging rod, and the horizontal telescopic test rod via a first rotating shaft. A first torsion spring is sleeved on the first rotating shaft. A protrusion is provided on the opposite side of the ends of the two rotating rods. The protrusion cooperates with the double-headed spherical pin or the limiting ring on the spherical pin.

[0012] Optionally, the clamping mechanism includes a support rod fixedly connected to a ball pin. A servo motor is provided inside the support rod. The output shaft of the servo motor is connected to an upper rotating shaft and a lower rotating shaft respectively through a bevel gear assembly. The upper rotating shaft is connected to an upper clamping plate, and the lower rotating shaft is connected to a lower clamping plate. An electromagnet is provided on each opposite side of the upper and lower rotating shafts.

[0013] Optionally, the spherical pin is further provided with a limiting mechanism, which includes a Y-shaped insert rod. The Y-shaped insert rod is movably disposed in the channel of the spherical pin between the insertion position and the retracted position. When the Y-shaped insert rod is in the insertion position, the free end of the Y-shaped insert rod is located in the limiting ring, and when the Y-shaped insert rod is in the retracted position, the free end of the Y-shaped insert rod is located in the channel.

[0014] Optionally, the end of the Y-shaped insert rod away from the limiting ring is connected to the pull rod via a second rotating shaft, a second torsion spring is provided on the second rotating shaft, the other end of the pull rod is connected to the wire rope, and the other end of the wire rope is wound around the upper rotating shaft.

[0015] The beneficial effects of the high-altitude pipeline slope measuring device of the present invention are as follows: It sets up a vertical telescopic hanging rod and a horizontal telescopic test rod, forming a four-bar linkage between the horizontal telescopic test rod, the two vertical telescopic hanging rods, and the pipeline being measured. This ensures that the tilt angle of the horizontal telescopic test rod matches the slope of the pipeline being measured. By measuring the tilt angle of the horizontal telescopic test rod at a low altitude, the slope of the pipeline can be quickly obtained. The device is convenient and quick to operate, improving work efficiency and reducing the workload of workers. A convex lens is installed at the position corresponding to the pointer on the dial to magnify the pointer's position and facilitate reading. Attached Figure Description

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1-11 As shown, the high-altitude pipeline slope measuring device of the present invention includes: a vertical telescopic hanging rod 1, a horizontal telescopic test rod 2, a dial 3 and a pointer 4. There are two vertical telescopic hanging rods 1, and each of the two vertical telescopic hanging rods 1 is provided with a clamping mechanism 6 at its top end. The vertical telescopic hanging rod 1 is connected to the pipeline 5 to be measured through the clamping mechanism 6. The vertical telescopic hanging rod 1 can rotate relative to the clamping mechanism 6, so the vertical telescopic hanging rod 1 is always vertically downward.

[0039] The two ends of the horizontal telescopic test rod 2 are rotatably connected to the bottom of the two vertical telescopic hanging rods 1 respectively. The horizontal telescopic test rod 2, the vertical telescopic hanging rods 1 and the pipeline under test 5 form a four-bar linkage mechanism. Therefore, the horizontal telescopic test rod 2 is always parallel to the pipeline under test 5. The tilt angle of the horizontal telescopic test rod 2 is consistent with the tilt angle of the pipeline under test 5. The tilt slope of the pipeline under test 5 can be obtained by measuring the tilt angle of the horizontal telescopic test rod 2 located below.

[0040] The dial 3 is connected to the horizontal telescopic test rod 2 via a collar 201, and the dial 3 can rotate relative to the vertical telescopic hanging rod 1 along with the horizontal telescopic test rod 2. The pointer 4 is located at the bottom of one of the vertical telescopic hanging rods 1, inside the dial 3, and is equipped with a counterweight 402. Since the vertical telescopic hanging rod 1 is always pointing downwards, the pointer 4 is also always pointing downwards. The dial 3 can rotate with the horizontal telescopic test rod 2, so the dial 3 also rotates by a corresponding angle with the horizontal telescopic test rod 2. At this time, the pointer 4 points to the scale on the dial 3, which is the inclination slope of the pipeline 5 being tested.

[0041] The vertical telescopic hanging rod 1 includes a first vertical hanging rod 101 and a second vertical hanging rod 102. The first vertical hanging rod 101 and the second vertical hanging rod 102 are spaced apart on the pipeline 5 to be tested. The distance between the first vertical hanging rod 101 and the second vertical hanging rod 102 is equal to the length of the horizontal telescopic test rod 2.

[0042] The bottom of the first vertical hanging rod 101 is provided with a fixed connecting rod 103, which is perpendicular to the first vertical hanging rod 101. A collar 201 and a dial 3 are sleeved on the fixed connecting rod 102. The collar 201 and the dial 3 are fixedly connected, and both the collar 201 and the dial 3 are rotatably connected to the fixed connecting rod 103. The collar 201 and the dial 3 are rotatably connected to the fixed connecting rod 103 by a bearing. The collar 201 is detachably connected to the horizontal telescopic test rod 2, so the dial 3 and the horizontal telescopic test rod 2 can rotate synchronously.

[0043] like Figure 3 As shown, the collar 201 is connected to the horizontal telescopic test rod 2 by a snap fastener, so the horizontal telescopic test rod 2 and the vertical telescopic hanging rod 1 are detachably connected, which facilitates the storage of the horizontal telescopic test rod 2 and the vertical telescopic hanging rod 1.

[0044] like Figure 2 As shown, the dial 3 also includes a display disk 301 and a convex lens 302. The display disk 301 is located on the side closer to the collar 201, and the lower part of the display disk 301 has a scale. The convex lens 302 is located on the side away from the collar 201, and the convex lens 302 corresponds to the scale on the display disk 301. The pointer 4 is mounted on the fixed connecting rod 103 through the bearing 401. The pointer 4 is located between the display disk 301 and the convex lens 302, and the convex lens 302 is located on the outside, which facilitates reading.

[0045] The second vertical hanging rod 102 is connected to the horizontal telescopic test rod 2 by a double-headed ball pin 702. Both ends of the double-headed ball pin 702 are provided with limit rings 701. The second vertical hanging rod 102 and the horizontal telescopic test rod 2 are provided with locking mechanisms 8 at the connection position. The locking mechanisms 8 are detachably connected to the double-headed ball pin 702.

[0046] The locking mechanism 8 is located inside the second vertical hanging rod 102 and the horizontal telescopic test rod 2. The locking mechanism 8 is connected to one end of the locking switch 801, and the other end of the locking switch 801 passes through the second vertical hanging rod 102 and the horizontal telescopic test rod 2 respectively.

[0047] The locking mechanism 8 includes two rotating rods 802 hinged to the locking switch 801. The rotating rods 802 are L-shaped and are located inside the second vertical hanging rod 801 and the horizontal telescopic test rod 2 via a first rotating shaft 803. A first torsion spring 804 is sleeved on the first rotating shaft 803. Each end of the two rotating rods 802 has a protrusion 805 on its opposite side. The protrusion 805 cooperates with the limiting ring 701 on the double-headed ball pin 802. The protrusion 805 in the locking mechanism 8 at the position where the second vertical hanging rod 102 connects to the horizontal telescopic test rod 2 is connected to the limiting rings 701 at both ends of the double-headed ball pin 702.

[0048] by Figure 4 Based on this, when using the locking mechanism 8, first press the locking switch 801. The locking switch 801 moves to the right, thereby pushing the two rotating rods 802 to rotate around the first rotating shaft 803 to the upper and lower sides respectively. The rotation of the rotating rods 802 drives the protrusion 805 to move to the upper and lower sides. Then, the double-headed ball pin 702 is inserted into the locking mechanism 8. Release the locking switch 801. The two rotating rods 802 rotate under the action of the first torsion spring 804, so that the protrusion 805 will be inserted into the limiting ring 701 of the double-headed ball pin 702, thereby connecting the locking mechanism 8 and the double-headed ball pin 702. After both ends of the double-headed ball pin 702 are connected, the connection between the second vertical hanging rod 102 and the horizontal telescopic test rod 2 can be completed, and the second vertical hanging rod 102 can rotate relative to the horizontal telescopic test rod 2.

[0049] The tops of both the first vertical hanging rod 101 and the second vertical hanging rod 102 are connected to the clamping mechanism 6 via a locking mechanism 8 and a ball pin 7. The ball pin 7 is fixedly connected to the clamping mechanism 6, while the locking mechanism 8 is detachably connected to the ball pin 7. Both the tops of the first vertical hanging rod 101 and the second vertical hanging rod 102 are equipped with a locking mechanism 8. A limit ring 701 is provided on the ball pin 7. The connection method between the ball pin 7 and the locking mechanism 8 is the same as the connection method between the double-headed ball pin 702 and the locking mechanism 8.

[0050] The clamping mechanism 6 includes a support rod 7 fixedly connected to a ball pin 7. A servo motor 607 is housed inside the support rod 7. The output shaft of the servo motor 607 is connected to an upper rotating shaft 604 and a lower rotating shaft 605 respectively via a bevel gear assembly. The upper and lower rotating shafts 604 and 605 are arranged opposite to each other, and their rotation directions are opposite. The upper rotating shaft 604 is connected to an upper clamping plate 602, and the lower rotating shaft 605 is connected to a lower clamping plate 603, causing the upper and lower clamping plates 602 and 603 to move towards each other, thereby clamping the pipeline 5 under test. Anti-slip pads are also provided inside the upper and lower clamping plates 602 and 603 to ensure they clamp the pipeline 5 under test and prevent the entire device from moving due to human intervention.

[0051] Electromagnets 606 are provided on opposite sides of the upper rotating shaft 604 and the lower rotating shaft 605.

[0052] In practical use, first start the servo motor 607. The servo motor 607 drives the upper rotating shaft 604 and the lower rotating shaft 605 to rotate through the bevel gear set, thereby causing the upper clamping plate 602 and the lower clamping plate 603 to clamp the pipeline 5 to be tested. After clamping, energize the electromagnet 606 and stop the servo motor 607. The electromagnets 606 located at the ends of the upper rotating shaft 604 and the lower rotating shaft 605 attract each other, thereby stopping the upper rotating shaft 604 and the lower rotating shaft 605 from rotating, thus fixing the upper clamping plate 602 and the lower clamping plate 603.

[0053] The spherical pin 7 is also provided with a limiting mechanism 9, which includes a Y-shaped insert 901, a pull rod 902, a wire rope 903 and a spring 904. The Y-shaped insert 901 is movably disposed in the channel 703 of the spherical pin 7 between the insertion position and the retracted position. When the Y-shaped insert 901 is in the insertion position, the free end is located in the limiting ring 701, and when the Y-shaped insert 901 is in the retracted position, the free end is located in the channel 703.

[0054] When the Y-shaped plug 901 is in the insertion position, one of the protrusions 805 in the locking mechanism 8 at the top of the first vertical hanging rod 101 and the second vertical hanging rod 102 is located in the middle of the Y-shaped plug 901, thereby restricting the rotation between the locking mechanism 8 and the ball pin 7. At this time, the rotation of the clamping mechanism 6 is also restricted, thereby enabling the clamping mechanism 6 to be clamped onto the pipeline 5 to be tested more quickly and accurately.

[0055] When the Y-shaped insert 901 is in the retracted position, the protrusion 805 disengages from the Y-shaped insert 901 and can rotate along the limiting ring 701. The first vertical hanging rod 101 and the second vertical hanging rod 102 can rotate relative to the clamping mechanism 6.

[0056] One end of the Y-shaped insert 901 away from the limiting ring 701 is connected to the pull rod 902 via a second rotating shaft. A second torsion spring is installed on the second rotating shaft, which keeps the two rods of the Y-shaped insert 901 in a forked state. The other end of the pull rod 902 is connected to the wire rope 903, and the other end of the wire rope 903 is wound around the upper rotating shaft 604. The rotation of the upper rotating shaft 604 causes the wire rope 903 to wind around the upper rotating shaft 604. The winding of the wire rope 903 drives the pull rod 902 to move closer to the upper rotating shaft 604. The movement of the pull rod 902 drives the Y-shaped insert 901 to move along the channel 703, thereby moving the Y-shaped insert 901 from the insertion position to the retracted position, allowing the first vertical hanging rod 101 and the second vertical hanging rod 102 to rotate relative to the clamping mechanism 6.

[0057] One end of the spring 904 is connected to the inner wall of the support rod 601, and the other end is connected to the side wall of the pull rod 902. When the upper clamping plate 602 and the lower clamping plate 603 clamp the pipeline 5 to be measured, the pull rod 902 moves towards the side closer to the upper rotating shaft 604, and the spring 904 is stretched and in a deformed state. When the slope measurement is completed, the electromagnet 606 is de-energized, the spring 904 contracts, and the pull rod 902 pulls the upper rotating shaft 604 to rotate in the opposite direction through the wire rope 903. The upper clamping plate 602 and the lower clamping plate 603 are released and can be separated from the pipeline 5 to be measured.

[0058] In order for the protrusion 805 in the locking mechanism 8 to disengage from the Y-shaped insert 901, the length of the wire rope 903 wound on the upper rotating shaft 604 is greater than the width of the limiting ring 701, that is...

[0059] l≥L (1)

[0060] Where l is the length of the wire rope 903 wound on the upper rotating shaft 604, and L is the width of the limiting ring 701.

[0061] In order for the Y-shaped insert 901 to be smoothly inserted into the limiting ring 701 after the electromagnet 606 is de-energized, the two rods of the Y-shaped insert 901 must not disengage from the inclined channel 703 in the spherical pin 7. That is, the length of the wire rope 903 wound on the upper rotating shaft 604 must be less than the horizontal displacement of the Y-shaped insert 901.

[0062] l≤S+L (2)

[0063] Where l is the length of the wire rope 903 wound on the upper rotating shaft 604, L is the width of the limiting ring 701, and S is the length of the projection of the channel 703 onto the length of the wire rope 903.

[0064] From (1) and (2), we can obtain

[0065] L≤l≤S+L (3)

[0066] The length of the wire rope 903 wound on the upper rotating shaft 604 is equal to the arc length of the corresponding angle on the upper rotating shaft 604, that is...

[0067]

[0068] Where l is the length of the wire rope 903 wound on the upper rotating shaft 604, n is the central angle corresponding to the arc length of the wire rope 903 wound on the upper rotating shaft 604, and r is the radius of the upper rotating shaft.

[0069] The length of the projection of channel 703 onto the length of wire rope 903 is,

[0070] S=Bcosα-L (5)

[0071] Where S is the length of the projection of channel 703 onto the length of wire rope 903, B is the length of the Y-shaped insert, α is half the included angle of the inclined channel 703, and L is the width of the limiting ring 701.

[0072] Combining formulas (3), (4), and (5), we can obtain that

[0073]

[0074] Where L is the width of the limiting ring 701, n is the central angle corresponding to the arc length of the wire rope 903 wound on the upper rotating shaft 604, r is the radius of the upper rotating shaft, B is the length of the Y-shaped insert 901, and α is half the included angle of the inclined channel 703.

[0075] As can be seen from formula (6), by controlling the angle n of the steel wire rope 903 rotating on the upper rotating shaft 604, that is, adjusting the radius of the upper rotating shaft 604, the angle n is made to satisfy the maximum rotation angle of the upper clamping plate 602 and the lower clamping plate 603, and the moving distance of the steel wire rope 903 corresponding to the angle n is not greater than the maximum horizontal distance of the Y-shaped insert rod 901, so that the Y-shaped insert rod 901 always moves in the channel 703, ensuring that the Y-shaped insert rod 901 does not leave the channel 703.

[0076] The display dial 301 uses the vertical line as the boundary, with one side of the fixed horizontal telescopic test rod 2 having positive values ​​and the other side having negative values. The slope of the pipeline is judged based on the angle reading presented by the pipeline under test 5.

[0077] In use, first place the first vertical hanging rod 101 on the pipeline 5 to be tested, then adjust the first vertical hanging rod 101 to a suitable length, assemble the dial 3 and the horizontal telescopic test rod 2, so that the height of the display dial 301 in the dial 3 is easy to observe, and then assemble the second vertical hanging rod 102 at the other end of the horizontal telescopic test rod 2. The telescopic amount of the first vertical hanging rod 101 and the second vertical hanging rod 102 must be the same, and the pipeline 5 to be tested, the horizontal telescopic test rod 2, the first vertical hanging rod 101 and the second vertical hanging rod 102 form a four-bar linkage mechanism. After placement, the bearing 401 and the pointer 4 form an angle on the display dial 301. After the device is stable, the counterweight 402 no longer shakes, and the angle is the slope of the pipeline.

[0078] like Figure 11 As shown, the slope of the tested pipeline 5 is the angle between the tested pipeline 5 and the horizontal line, i.e., ∠1. Because the first vertical hanging rod 101 and the second vertical hanging rod 102 are of equal length and are perpendicular lines, the horizontal telescopic test rod 2 and the tested pipeline 5 are parallel lines to each other. The angles formed by the two pairs of parallel lines are equal, i.e., ∠1.

[0079] ∠1=∠2

[0080] The horizontal telescopic test rod 2 is fixed to the dial 3, and the horizontal telescopic test rod 2 always forms a 90° angle with the 0° mark on the dial 3. After the measurement stabilizes, due to the action of the counterweight, the pointer 4 points vertically downwards, forming a 90° angle with the horizontal line.

[0081] ∠2 + ∠3 = 90°

[0082] ∠3 + ∠4 = 90°

[0083] so

[0084] ∠2=∠4

[0085] so

[0086] ∠1=∠4

[0087] ∠4 is the angle between pointer 4 and display dial 301, which is the angle displayed on display dial 301. The slope of the pipeline 5 being measured is measured by reading the dial.
