Description

TECHNICAL FIELD

[0001] The utility model relates to the field of inclination measuring device, especially a tunnel hanging column installation surface inclination measuring device BACKGROUND

[0002] The tunnel hanging column is installed on the top of the tunnel and is used for supporting the overhead cable in the contact network in the tunnel. Figures 1-3 As shown in the figure, the tunnel hanging column comprises a support column 1 and a suspension top plate 2 welded and fixed on the top of the support column 1, the suspension top plate 2 is a square plate, and a long strip-shaped top plate mounting hole 5 is arranged at each corner of the suspension top plate 2. Figure 4 As shown in the tunnel arc top view, the dashed line in the figure represents the tunnel trend line and the dashed line position is the tunnel arc top center line, in some construction processes, the installation center of the hanging column needs to be arranged offset from the tunnel arc top center line, and there is a certain distance requirement between the tunnel arc top center and the installation center of the hanging column, therefore, before installation, the construction personnel need to mark at the pre-buried installation position on the top of the tunnel according to the corresponding distance requirement, such as the mark line 1 and the mark line 2 in the figure, and mark symbol lines I and II are arranged at the center positions of the adjacent two holes of the suspension top plate 2, as shown in the figure. Figure 2 When installing, the construction worker first adjusts and transports the tunnel hanging column to the pre-buried installation position 31 on the top of the tunnel through the adjusting and transporting equipment, then passes the T-shaped bolt installed in advance at the four installation surface mounting holes on the pre-buried installation position 31 through the long strip-shaped top plate mounting hole 5 on the suspension top plate, respectively corresponds the mark line 1 with the mark symbol line I, and the mark line 2 with the mark symbol line II, and then fastens the suspension top plate to the top of the tunnel through the nut.

[0003] Due to actual construction errors, the installation surface on the top of the tunnel has inclination deviation relative to the preset reference installation surface, so that the tunnel hanging column after installation cannot meet the perpendicularity requirement perpendicular to the track surface. After the installation of the tunnel hanging column is completed, the construction personnel need to measure the perpendicularity of the tunnel hanging column, according to the measured perpendicularity deviation, the construction personnel need to adjust and transport the installed tunnel hanging column again through the adjusting and transporting equipment, then adjust the gasket quantity at the four fixed installation holes on the suspension top plate 2 to compensate for the deviation value of the installation surface on the top of the tunnel, so that the tunnel hanging column meets the perpendicularity requirement, and the construction personnel re-fix and install the tunnel hanging column after the adjustment is completed.

[0004] Due to the existence of the installation surface deviation on the top of the tunnel, for the hanging column that does not meet the requirement of perpendicularity, the construction personnel often need to adjust and transport multiple times to successfully install the hanging column, because the weight of the tunnel hanging column is heavy, it is extremely inconvenient to move, therefore, this kind of installation method is time-consuming and labor-intensive, and also reduces the installation efficiency of the tunnel hanging column.

[0030] This invention features an inclination measurement module mounted on a mounting base identical to that of a suspended roof panel, forming the main body of an inclination measurement device. This device measures the inclination of the mounting surface. Before the tunnel suspension column is installed, the mounting base of the measuring device is placed close to the mounting surface at the top of the tunnel. The data measured by the inclination measurement device can then be directly used as a reference for the suspended roof panel. This allows the required number of shims to be pre-set between the four roof panel mounting holes and the corresponding four mounting surface mounting holes before the tunnel suspension column is installed.

[0031] Based on the above-mentioned inventive concept, the tunnel suspension column mounting surface inclination measuring device of this utility model, as follows: Figures 5-6 As shown, the device includes a main body of a measuring device, which includes a mounting base 7 with the same structure as the suspended ceiling of the tunnel column and a measuring module 8 disposed on one side of the mounting base. The other side of the mounting base 7 is a measuring contact surface for contacting the mounting surface of the tunnel column. The measuring module 8 includes an inclination sensor 11 for measuring the inclination of the mounting surface and a battery 12 for providing power to the inclination sensor.

[0032] Because the structure of the mounting base 7 is the same as that of the suspended ceiling panel 2, the mounting base 7 is provided with a base mounting hole 71, and the position of the base mounting hole 71 is the same as that of the ceiling panel mounting hole 5 on the suspended ceiling panel 2. The mounting base 7 is provided with a marking symbol line at the center position of the line connecting the two corresponding base mounting holes 71, which corresponds to the marking symbol line I18 and marking symbol line II19 on the suspended ceiling panel 2, respectively. The marking symbol line is set perpendicular to the side of the mounting base 7.

[0033] During measurement, the four mounting holes 71 on the main mounting base 7 of the measuring device, the four mounting holes 5 on the suspended roof 2, and the four mounting holes on the tunnel top mounting surface corresponding to the tunnel suspension column during installation should be properly aligned and marked with letters. Then, the construction personnel should precisely attach the mounting base 7 to the corresponding mounting surface on the tunnel top, following the installation method of the suspended roof 2.

[0034] The inclination sensor 11 is a two-axis or three-axis sensor, which can measure the inclination of the installation surface relative to the reference plane, the reference plane is the horizontal plane, and the installation points corresponding to the lowest installation hole of the four installation surface installation holes on the installation surface are located on the horizontal plane, the lowest installation point is marked as O point, and the installation points corresponding to the remaining three installation surface installation holes are marked as A, B, and C points. When measuring, marks corresponding to the installation surface installation holes are made on the four base installation holes 71 on the installation base 7 and the four top plate installation holes 5 on the suspended top plate 2. In order to make the measured data easier to process later, the inclination sensor 11 is arranged at the center position of the installation base 7, and the inclination sensor 11 is symmetrically arranged with the center of the installation base 7 as the center. In other embodiments, the inclination sensor 11 can also be arranged at other positions of the installation base 7 according to actual conditions. The inclination sensor 11 can be an analog output, or can use communication and a controller to interact data.

[0035] When measuring, the construction personnel can install the installation base 7 on the corresponding installation surface at the top of the tunnel with the help of external tools. In a preferred embodiment, in order to facilitate operation, the installation base 7 is provided with a handle 20, and the handle 20 is provided with two, which are respectively located on both sides of the module shell 9. The construction personnel can hold the handles on both sides of the measurement module 8 to move the installation base 7 to the corresponding installation position. In other embodiments, the handle 20 can also be provided with one, and the handle 20 is arranged along the long edge direction of the installation base 7, and both ends of the handle 20 are fixed to the center positions of the two short edges of the installation base 7.

[0036] The measurement module 8 comprises a module shell 9, which is a hollow shell structure, and the module shell 9 is arranged at the center position of the installation base. The inclination sensor 11 and the battery 12 are arranged inside the module shell 9, the sensor 11 is arranged at the center position inside the module shell 9, and the module shell 9 can protect the inclination sensor 11 and the battery 12 inside.

[0037] In order to facilitate the construction personnel to observe the measurement data in real time when measuring, the measurement module 8 further comprises a display screen 14 and a controller 13. The display screen 14 is arranged on the shell wall of the module shell 9, and the controller 13 is arranged inside the module shell 9 and connected with the display screen 14 and the inclination sensor 11. The controller 13 is used for analyzing and calculating the data measured by the inclination sensor 11, and the display screen 14 is a display screen for displaying measurement data.

[0038] The first relative height deviation of the four installation surface installation holes relative to the horizontal plane is obtained by analyzing and calculating the inclination data measured by the inclination sensor 11 in combination with the length and width dimensions of the suspension top plate 2, and the first relative height deviation is the height difference value of the A, B and C installation points of the installation surface installation holes relative to the lowest point O corresponding to the lowest installation surface installation hole; the second relative height deviation of the four top plate installation holes on the suspension top plate 2 of the tunnel hanging column relative to the horizontal plane is obtained when the support column 1 of the tunnel hanging column is kept in a free vertical state, and the second relative height deviation is the height difference value of the A, B and C installation points of the three top plate installation holes 5 corresponding to the installation surface installation hole marks on the top plate installation hole 5 of the suspension top plate 2 relative to the lowest point O corresponding to the lowest top plate installation hole; the lowest point O is located on the horizontal plane. Then, the third relative height deviation of the four installation surface installation holes relative to the four top plate installation holes is obtained by subtracting the first height deviation from the second height deviation, and the third relative height deviation is the height difference value between the A, B and C installation points of the measured installation surface installation holes and the A, B and C installation points of the three top plate installation holes 5 corresponding to the installation surface installation hole marks on the suspension top plate 2 to be installed. The display screen 14 displays the deviation value of the third relative height deviation, and the construction personnel pre-allocate the gaskets according to the third relative height deviation value.

[0039] The display screen 14 is of a touch screen type, and can be operated by the measurer to save, browse, delete, re-enter and flip up and down the data. The display screen 14 can be installed in a plane or fixed on the shell wall of the measuring module 8 by a folding support, and the folding support can rotate the display screen 14 to a position convenient for the construction personnel to observe the data.

[0040] The measuring module 8 further comprises a power button 15 and a confirmation button 16 arranged on the shell wall of the module shell 9, and the confirmation button 16 is connected with the controller 13. The power button 15 is used to control the power-on and power-off of the measuring device, and the confirmation button 16 is a detection information confirmation key. After the construction personnel fix the installation base 7 of the measuring device at the hanging column installation position on the top of the tunnel, the power button 15 is pressed, the whole system is powered on, and after 1-2 seconds, the measuring parameters are stabilized, the confirmation button 16 is pressed, and the controller 13 calculates and analyzes the data according to the detection information of the inclination sensor 11 at this time. After the measurement is completed, the power button 15 is pressed to complete the system power-off. According to the interface signal requirement of the controller 13, high-level signals or low-level signals can be selected, and the signals are directly connected with the IO interface of the controller 13 or can be converted through an IO module. The power button 15 is a self-locking button, and the confirmation button 15 is a point touch type button.

[0041] As Figure 11As shown, the measuring device also includes a mobile terminal that is communicatively connected to the measuring module of the main body of the measuring device. The mobile terminal can be a remote synchronization tablet computer, used to synchronize data with the display screen 14. The controller 13 receives and processes the data measured by the tilt sensor 11. Through coordinate transformation, the controller 13 calculates the required shim data for the four mounting holes 71 of the mounting base 7 during fixed installation and transmits the data to the display screen 14 and the remote synchronization tablet computer. The remote synchronization tablet computer synchronizes data with the display screen 14 of the measuring device, facilitating pre-installation of shims by construction personnel based on the data.

[0042] Based on the three actual operating conditions, the specific calculation process of controller 13 is as follows:

[0043] Working Condition 1: The suspended ceiling of the tunnel support column is perpendicular to the supporting column, such as... Figure 1 As shown. In this state, the angle between the suspended ceiling and the horizontal coordinate system xoy is 0, that is, the second relative height deviation is 0, and the first relative height deviation obtained by measurement is equal to the third relative height deviation.

[0044] Variable description:

[0045] θ x : The angle between the plane where the mounting base is located and the positive x-axis of the horizontal plane;

[0046] θ y : The angle between the plane where the mounting base is located and the positive y-axis of the horizontal plane;

[0047] Parameters: 2a and 2b are the length and width of the mounting base, which are also the length and width of the suspended ceiling panel.

[0048] x0, y0, and z0 are the coordinates of the lowest point O with the tilt sensor 11 as the origin. Let the tilt sensor 11 be...

[0049] The location is point Y, such as Figure 10 As shown, point Y is located at the center of rectangle OABC, which corresponds to the four mounting holes 71 on the mounting base 7. The lowest mounting position of the mounting base 7 of the measuring device is point O, and the other mounting positions are points A, B, and C. Figure 7 As shown, OA = BC = 2a, OB = AC = 2b, as Figure 7 As shown.

[0050] 1. With Y as the origin, the coordinates of point O are...

[0051] (1) Assume that the angle between the inclined plane and the y-axis of the standard horizontal plane is θ. yIf the value is positive, the lowest point O has a negative coordinate y0 on the y-axis, that is, the angle θ and the corresponding coordinate value have opposite signs, so the positive and negative of y0 can be represented as -θ y |θ y |.

[0052] (2) From Figure 7 we can know that and from (1) we can get

[0053] -90° < θ < 90° y <90°

[0054] Similarly, we can get -90° < θ < 90° x <90°

[0055] (3) The Y point and position are shown in Figure 10 From the figure, we can get

[0056]

[0057] The coordinates of points A, B, and C with O as the origin are:

[0058] From the above, we know that the coordinates of point O relative to point Y are (x0, y0, z0), and point O and point C are always symmetric about point Y, so the coordinates of point C relative to point O are (-2x0, -2y0, -2z0).

[0059] Then from Figure 7 we can get the longitudinal axis coordinates of point A with O as the origin:

[0060]

[0061] The longitudinal axis coordinates of point B are:

[0062]

[0063] Point A is on the Y-axis and point B is on the X-axis, so with O as the origin, the coordinates of point A are A(0, -2y0, z1) and B(-2x0, 0, z2). From the above formula, we can get the longitudinal axis coordinates of points A, B, and C respectively:

[0064]

[0065] z1 = 2a |sinθ y |

[0066] z2 = 2b |sinθ x |

[0067] Case two: The suspended ceiling and the support column are not perpendicular, as shown in Figure 3As shown, there is an included angle between the x-axis of the horizontal plane of the suspended ceiling, i.e. the second relative height deviation is not 0.

[0068] Variable description:

[0069] θ x : the included angle between the plane where the mounting base is located and the positive direction of the x-axis of the horizontal plane;

[0070] θ y : the included angle between the plane where the mounting base is located and the positive direction of the y-axis of the horizontal plane;

[0071] 90°-α: the included angle between the suspended ceiling and the positive direction of the x-axis of the horizontal plane.

[0072] Parameters: 2a and 2b are the length and width of the mounting base, i.e. the length and width of the suspended ceiling.

[0073] x0, y0 and z0 are the coordinates of the lowest point O when the tilt sensor 11 is taken as the origin, and the position of the tilt sensor 11 is Y, as shown. Figure 10 As shown, Y is located at the center point of the rectangle OABC, which corresponds to the four base mounting holes 71 on the mounting base 7, and the lowest mounting position of the mounting base 7 of the measuring device is O, and the other mounting positions are A, B and C respectively. In the initial state, the angle between the suspended ceiling 2 and the positive direction of the x-axis of the horizontal plane of the top of the support column is 90°-α.

[0074] Let OA=BC=2a, OB=AC=2b, θ' x =θ x -90°+α, θ' x , which is the measured included angle between the mounting surface and the x-axis of the horizontal plane minus the included angle between the suspended ceiling and the x-axis of the horizontal plane, as shown. Figure 8

[0075] 1. Taking Y as the origin, the coordinates of the O point are

[0076] (1) Assuming that the included angle θ y between the inclined plane and the standard plane Y-axis is positive, the y-axis coordinate y0 of the lowest point is negative, i.e. the positive and negative signs of the included angle and the corresponding coordinate value are opposite, so the positive and negative of y0 can be represented as -θ y / |θ y .

[0077] (2) From Figure 8 , we can know that and from (1), we can get

[0078] -90°<θ y <90°

[0079] Similarly, we can get -90°<θ​x <90

[0080] (3) Y point ordinate position as shown in the figure, can be obtained from the figure, Figure 10

[0081]

[0082] The position coordinates of points A, B, C with O as the origin are:

[0083] From the above, the position coordinates of point O relative to point Y are (x0, y0, z0), and point O and point C are always symmetric about point Y, so the position coordinates of point C relative to point O are (-2x0, -2y0, -2z0).

[0084] As shown in Figure 8 , with O as the origin, the ordinate of point A is

[0085]

[0086] The ordinate of point B is

[0087]

[0088] Point A is on the Y axis and point B is on the X axis, so with O as the origin, the coordinates of point A are A(0, -2y0, z1) and B(-2x0, 0, z2)

[0089] From the above formula, the ordinate coordinates of points A, B, C are respectively

[0090]

[0091] z1 = 2a |sinθ y |

[0092] z2 = 2b |sinθ x |

[0093] Case three: The suspended ceiling and the support column are not perpendicular, and there is an angle between the suspended ceiling and the horizontal plane y axis, i.e. the second relative height deviation is not 0.

[0094] Variable description:

[0095] θ x : The angle between the plane where the mounting base is located and the positive direction of the horizontal x axis;

[0096] θ y : The angle between the plane where the mounting base is located and the positive direction of the horizontal y axis;

[0097] 90°-β: The angle between the suspended ceiling and the support column horizontal plane Y axis positive direction;

[0098] ​Parameters: 2a, 2b are the length and width of the mounting base, i.e. the length and width of the suspended top plate.

[0099] x0, y0, z0 are the coordinates of the lowest point O with the tilt sensor 11 as the origin, and the position of the tilt sensor 11 is Y, as shown in FIG. 1, Y is located at the center of the rectangle OABC, which corresponds to the four base mounting holes 71 on the mounting base 7, and the lowest mounting position of the mounting base 7 of the measuring device is O, and the other mounting positions are points A, B, and C. In the initial state, the angle between the top plate 2 and the x-axis positive direction of the horizontal plane at the top of the support column is 90°-β. Figure 10

[0100] Let θ' y = θ y -90°+β, OA=BC=2a, OB=AC=2b, θ' y , which is the measured angle between the mounting surface and the horizontal y-axis minus the angle between the suspended top plate and the horizontal y-axis, as shown in FIG. 2. Figure 9

[0101] 1. With Y as the origin, the coordinates of point O are

[0102] (1) Assuming that the angle between the inclined plane and the standard plane Y-axis is θy, which is positive, then the y-axis coordinate y0 of the lowest point is negative, i.e. the sign of the angle and the corresponding coordinate value is opposite, so the y0 positive and negative can be represented as -θ y / |θ y .

[0103] (2) From Figure 9 , we can know that and from (1), we can get

[0104] (3) -90°<θ y <90

[0105] Similarly, we can get -90°<θ x <90

[0106] The vertical coordinate position of point Y is shown in FIG. 3, and from the figure we can get Figure 7

[0107]

[0108] With O as the origin, the position coordinates of points A, B, and C are:

[0109] As can be seen from the above, the position coordinates of point O relative to point Y are (x0, y0, z0), and point O and point C are always symmetric about point Y, so the position coordinates of point C relative to point O are (-2x0, -2y0, -2z0). ​​​

[0110] As shown in Figure 9 The vertical axis coordinate of point A is:

[0111]

[0112] The vertical axis coordinate of point B is:

[0113]

[0114] Point A is on the Y axis and point B is on the X axis, so the coordinates of point A are A(0, -2y0, z1) and B(-2x0, 0, z2) with O as the origin. The vertical axis coordinates of points A, B, and C are respectively,

[0115]

[0116] z1 = 2a|sinθ' y |

[0117] z2 = 2b|sinθ x |

[0118] According to the above three working conditions, the controller calculates the third relative height deviation Z1, Z2, 2Z0 between the A, B, and C points corresponding to the remaining three mounting hole installation surfaces except for the lowest point O and the A, B, and C points corresponding to the top plate mounting hole 5 of the tunnel hoist column to be installed, i.e. the required gasket height is Z1, Z2, 2Z0 respectively. These data will be directly displayed on the display screen 14 and simultaneously transmitted to the remote synchronization tablet computer held by the ground construction personnel through wired or wireless transmission. The ground construction personnel will complete the gasket pre-arrangement according to the display on the remote synchronization computer, and after the pre-arrangement is completed, the hoist column will be installed.

[0119] When the measurement data is inaccurate or has errors, the measurement can be performed again, and the display screen 14 is operated to delete the data in the system. After re-measurement, the new data is associated and stored with the number on the fixed mounting point on the suspended ceiling 2. At the same time, the measuring device has data query, up and down page, and other operations.

[0120] The whole measuring device can be powered by a battery, and a charging interface is reserved for direct current charging by a charger. The battery voltage is generally standard DC 24V or DC 12V, and the rated power supply voltage of the tilt sensor 11, the controller 13 and the display screen 14 needs to be consistent with the battery voltage. The battery generally uses a lithium iron phosphate battery with high single capacity. In other embodiments, other batteries with strong endurance can also be used instead. In addition, the battery uses 485 or other bus mode to communicate data with the controller, and can upload the battery SOC information to the controller 13, which is sent to the display screen 14. The display screen 14 can display the battery power through power indication or digital display. The construction personnel can easily master the power information and charge in time to avoid affecting the engineering construction due to low power.

[0121] The power button 15 controls the whole system power supply by controlling the positive output of the battery. The metal shell can be grounded and shared as a negative pole, or double-line isolated power supply can be used. When double-line isolated power supply is used, the shells of all electrical devices need to be grounded and shared, which helps the stability of communication and signal transmission. Similarly, the power button 15 can also control the negative pole to control the whole system power supply.

[0122] The confirmation button 16 signal can be triggered by high level or low level according to the controller port form. Each trigger corresponds to the numbering of the top plate mounting hole 5 once, and confirms the data saving once. If there is an error in storage, the display screen 14 virtual button can be used to delete and re-measure the data.

[0123] The remote tablet computer synchronizes information with the measuring device main body. The remote tablet computer only displays data, and the operation is only changed by the measuring device main body. The information synchronization mode can be wireless such as Bluetooth or WIFI, or wired connection.
