Description

Technical Field

[0001] The present invention complies with the technical field of pipeline measuring equipment, and specifically relates to a detection device used for the construction of an urban underground comprehensive pipeline gallery. Background Art

[0002] A comprehensive pipe gallery is a tunnel space built underground in a city, which is specially used to accommodate and organize various municipal pipelines (such as power pipelines, communication pipelines, gas pipelines, etc.). Comprehensive pipe galleries are divided into circular corridors, square corridors, single-bottom-tank pipe galleries, double-bottom-tank pipe galleries, etc. During the construction of the pipe gallery, prefabricated parts are usually used for laying directly. After the production of the prefabricated pipe gallery, it is necessary to measure the positions and pipe diameters of the various circular holes and semi-circular holes (semi-open circular hole grooves) that accommodate pipes in it to avoid laying unqualified pipe gallery prefabricated parts, resulting in the misalignment of the circular holes in the pipe gallery prefabricated parts, which affects the normal laying of the pipeline. The way to measure the prefabricated pipe gallery parts is to directly use the existing intelligent measurement of the inner diameter of the pipeline. Measuring device, the existing pipeline inner diameter measuring device usually opens several legs synchronously, and the several legs are in contact with the inner wall of the pipeline, so that the measuring device moves into the pipeline at the axial position of the pipeline, so as to use a laser sight to measure the inner diameter of the pipeline. However, since the semicircular holes in the pipeline gallery are open semicircular structures, the legs of the existing measuring device are unable to obtain effective support during the opening process of the semicircular holes. As a result, it is difficult for the existing measuring device to stably move along the axis of the semicircular holes.

[0031] Embodiment 1: Because when measuring the inner diameters of various circular holes in prefabricated parts of the existing corridor, the existing intelligent pipe inner diameter measuring device is usually used directly for measurement, and the existing pipe inner diameter measuring device can only measure the complete circular holes in the corridor, and cannot move along the inner wall of the semicircular holes in the corridor. Therefore, the existing measuring device cannot intelligently measure the diameter of the semicircular holes in the corridor. The staff can only use the existing device to measure the circular holes in the corridor, and then use tools such as tape measures to estimate the diameter and orientation of the semicircular holes in the corridor, resulting in poor measurement accuracy of the semicircular holes in the corridor.

[0034] Reference Figure 4-Figure 6 As shown, the power component includes two extrusion blocks 17 symmetrically distributed front and back, the two extrusion blocks 17 are respectively hinged to the rear side of the adjacent first swing rod 8 and the front side of the adjacent fourth swing rod 14, a third electric shaft 18 electrically connected to the remote control terminal is installed on the extrusion block 17, the third electric shaft 18 is installed with an electric wheel 19 electrically connected to the remote control terminal, the third electric shaft 18 drives the electric wheel 19 to rotate, thereby ensuring that the device moves forward along different routes, the outer side of the electric wheel 19 is an arc surface, which is used to ensure that the electric wheel 19 and the inner wall of the pipe gallery 101 There is always only one contact point between them to ensure that the electric wheel 19 can keep in contact with the adjacent inner wall of the pipe gallery 101 when rotating in any direction. The ball on the extrusion block 17 is connected to a rolling ball. The rolling ball and the adjacent electric wheel 19 jointly provide support for the adjacent extrusion block 17, thereby preventing the extrusion block 17 from shaking during the support process. The first swing arm 8 and the adjacent fourth swing arm 14 are both fixedly connected to the limit block 20. The limit block 20 squeezes the adjacent extrusion block 17 to prevent the adjacent extrusion block 17 from rotating too much. The parts thereon cannot fit with the inner wall of the pipe gallery 101.

[0035] Reference Figure 5-Figure 7As shown, the adaptable component includes a fixed plate 21, which is fixed to the rear side of the prism 12, and the fixed plate 21 is slidably connected to a moving frame 22. The front side of the moving frame 22 is hinged with a fifth swing rod 23, and the fifth swing rod 23 is hinged to the adjacent third swing rod 10. When the fifth swing rod 23 moves following the telescopic end of the first electric push rod 11 through adjacent components, it synchronously drives the adjacent third swing rod 10 to swing.

The front side of the prism 12 is slidably connected to a limiting member 25, and a spring is fixed between the limiting member 25 and the prism 12 for determining the reset position of the adjacent moving frame 22. The moving frame 22 is provided with a limiting groove that cooperates with the upper limit ball of the adjacent limiting member 25.

[0036] Reference Figure 1 and Figure 8 As shown, the sliding rod 103 is slidably connected with two extrusion pieces 27 which are symmetrically distributed on the left and right. The extrusion pieces 27 are extruded and matched with the adjacent platforms 102. The contact surfaces between the extrusion pieces 27 and the adjacent platforms 102 are smooth surfaces. Therefore, when the two extrusion pieces 27 are extruded with the two platforms 102, the friction force on the extrusion pieces 27 is small, and the movement of the extrusion pieces 27 and adjacent parts is not affected. The extrusion pieces 27 are rotatably connected with a second threaded rod 28, and the second threaded rod 28 is threadedly connected to the adjacent sliding rod 103. The second threaded rod 28 is used to drive the adjacent extrusion pieces 27 to move relative to the adjacent sliding rod 103.

[0037] After the production of the pipe gallery 101 is completed, when the staff inspects the dimensions of the pipe gallery 101 of the same batch, the staff first places the fixed block 1 between the two platforms 102 in the pipe gallery 101, and then the staff simultaneously rotates the two second threaded rods 28, and the two second threaded rods 28 simultaneously drive the adjacent extrusion members 27 to extend together. When the two extrusion members 27 are simultaneously squeezed and matched with the adjacent platforms 102, the fixed block 1 is limited between the two platforms 102. According to the production data of the pipe gallery 101, the staff gradually corrects the fixed block 1 to the center of the pipe gallery 101 by adjusting the fixed position between the two extrusion members 27 and the adjacent platforms 102, so that the axis of the pipe gallery 101 coincides with the axis of the first electric shaft 2. The staff then prepares to measure the position of each pipe hole.

[0038] By staff Figure 1Taking the measurement of the position of the semicircular hole in the middle of the right side of the middle pipe gallery 101 as an example, the staff first controls the first electric shaft 2 through the remote control terminal to drive the adjacent parts to rotate, and the first electric shaft 2 drives the first telescopic rod 3 and other parts to rotate to a vertical position. Then the staff controls the second electric shaft 4 through the remote control terminal to drive the second telescopic rod 5 and other parts to rotate to a horizontal position. At this time, the fixed shell 6 and the adjacent parts are located in the front position of the semicircular hole, and the fixed shell 6 and the adjacent parts are located on the upper right side of the semicircular hole (the initial position of the fixed shell 6 and the adjacent parts after adjustment is determined by the initial lengths of the first telescopic rod 3 and the second telescopic rod 5, which is used to leave a margin for subsequent measurements and increase the accuracy of subsequent measurements. Similarly, if the semicircular hole in the middle of the left side is measured, the fixed shell 6 and the adjacent parts are located on the upper left side of the semicircular hole to ensure that the first elastic member 51 and the second elastic member 52 work normally according to the following working principle during the measurement process, and for the pipe galleries 101 of the same batch, the margin is always in The determined value, that is, after the staff completes the above operation through the remote control device, the fixed shell 6 and the adjacent parts are always located at the upper right side of the semicircular hole. When it is necessary to measure different batches of pipe galleries 101, it is necessary to additionally adjust the telescopic end lengths of the second telescopic rod 5 and the first telescopic rod 3, so as to ensure that after the above operation, the fixed shell 6 and the adjacent parts are located at the upper right side of the semicircular hole). The staff inserts the fixed base 7 and the adjacent parts into the semicircular hole, and ensures that there are first swing rods 8 directly above and below the fixed base 7, and then rotates the first threaded rod 63. The first threaded rod 63 drives the baffle 62 to move upward, and the baffle 62 is no longer located at the opening of the fixed shell 6. The staff inserts the front side of the fixed base 7 into the opening of the fixed shell 6, and then the staff rotates the first threaded rod 63 to reset, and the first threaded rod 63 drives the baffle 62 to reset downward. The baffle 62 blocks the opening of the fixed shell 6 and limits the fixed base 7. At this time, the fixed shell 6 and the fixed base 7 are in a relatively fixed state.

[0039] After the staff controls the first threaded rod 63 to reset, the staff starts the first electric push rod 11 through the remote control terminal. The telescopic end of the first electric push rod 11 drives the prism 12 and other adjacent components to move forward. The prism 12 drives the adjacent fifth swing rod 23 to move forward together through the fixed plate 21, the adjacent third elastic member 24 and the adjacent moving frame 22. Take the upper first swing rod 8, i.e., the adjacent component, as an example (refer to Fig.11), the fifth swing rod 23 swings backward relative to the prism 12 during the movement, and the fifth swing rod 23 drives the adjacent third swing rod 10 to swing upward during the swinging process, and the swinging of the third swing rod 10 drives the adjacent second swing rod 9 and the adjacent first swing rod 8 to swing and open together, and the first swing rod 8 swings upward to drive the adjacent connecting member 16 to move upward together, and the adjacent multi-stage telescopic rod 15 is stretched, and the connecting member 16 drives the adjacent fourth swing rod 14 to swing upward, and because the connecting member 16 is located at the midpoint between the hinge of the adjacent first swing rod 8 and the fixed base 7 and the hinge of the adjacent fourth swing rod 14 and the fixed base 7, the upward swing angle of the fourth swing rod 14 is the same as the upward swing angle of the adjacent first swing rod 8, and the extrusion blocks 17 on the first swing rod 8 and the fourth swing rod 14 gradually contact the inner wall of the pipe gallery 101 during the upward swinging process, and the extrusion blocks 17 contact the inner wall of the pipe gallery 101 through the electric wheels 19 and the rolling balls thereon (the electric wheels 19 and the rolling balls are omitted hereinafter, and it is indirectly described as the extrusion blocks 17 contacting the inner wall of the pipe gallery 101).

[0040] Because the axis of the fixed base 7 is located at the upper right side of the adjacent semicircular hole on the pipe gallery 101, during the swinging process, the extrusion block 17 on the first swing rod 8 on the upper right side first contacts the inner wall of the pipe gallery 101, and at this time, the other extrusion blocks 17 do not contact the inner wall of the pipe gallery 101. Therefore, the first swing rod 8 continues to swing open under the drive of the adjacent parts, and the fixed base 7 and the adjacent parts are moved to the lower left side by the reaction force applied by the first swing rod 8 on the upper right side and the extrusion block 17 thereon, until the first swing rod 8 on the upper side and the extrusion block 17 thereon contact the inner wall of the pipe gallery 101 (that is, the extrusion block 17 is the second extrusion block 17 in contact with the inner wall of the pipe gallery 101), the fixed base 7 and adjacent components move in opposite directions under the reaction force of the two first swing rods 8 and the adjacent extrusion blocks 17 according to the same principle, until the lower extrusion block 17 contacts the inner wall of the pipe gallery 101, at this time, the upper and lower extrusion blocks 17 are in contact with the inner wall of the pipe gallery 101, the upper and lower first swing rods 8 can no longer be opened, the telescopic end of the first electric push rod 11 can no longer drag the prism 12 forward, the remote control terminal automatically closes the first electric push rod 11, and the axis of the fixed base 7 coincides with the axis of the adjacent semicircular hole of the pipe gallery 101.

[0041] When the fixed base 7 and adjacent parts are subjected to the reaction force of the extrusion block 17 in contact with the inner wall of the pipe gallery 101 and move in the opposite direction, the fixed base 7 drives the fixed shell 6 and adjacent parts to move together. When the fixed shell 6 moves to the left, it drives the telescopic end of the second telescopic rod 5 and the indicator rod 53 thereon to move to the left. The first elastic member 51 is compressed and stores force. When the fixed shell 6 moves downward, it drives the telescopic end of the first telescopic rod 3 and the indicator rod 53 thereon to move downward together through the second telescopic rod 5 and the second electric rotating shaft 4. The second elastic member 52 is stretched and stores force. When the fixed base 7 stops moving, the staff reads the indicator rod 5 on the telescopic end of the first telescopic rod 3. 3 and the value shown on the indicator rod 53 on the telescopic end of the second telescopic rod 5, read the extension of the telescopic end of the first telescopic rod 3 and the retraction of the telescopic end of the second telescopic rod 5, and then know the current length of the first telescopic rod 3 (that is, the distance between the axis of the semicircular hole and the center of the pipe gallery 101 in the vertical direction) and the current length of the second telescopic rod 5 (that is, the distance between the axis of the semicircular hole and the center of the pipe gallery 101 in the horizontal direction). The staff records the data and compares it with the data on the drawing to calculate whether the position of the axis of the semicircular hole is within a reasonable error range. After the staff completes the calculation, the positions of the semicircular holes or circular holes at other positions are measured according to the same principle.

[0042] After the staff has measured the orientations of all semicircular holes and circular holes, the staff is ready to measure the diameters of circular holes and semicircular holes. When measuring the diameters of the semicircular holes, the staff starts the electric wheel 19 through the remote control terminal. The electric wheel 19 that fits the inner wall of the pipe gallery 101 drives the adjacent parts to move backward by rotation. At this time, the extrusion piece 27 slides along the adjacent platform 102. The remote control terminal simultaneously starts the laser detector 13, and the laser detector 13 measures the distance between the inner walls of adjacent semicircular holes to measure the diameter of the semicircular hole there. When the staff measures the diameter of the circular hole, the staff rotates the first threaded rod 63 according to the above principle and removes the fixed base 7 from the fixed shell 6. Then the staff directly inserts the fixed base 7 and the adjacent parts into the circular hole to be measured. The staff controls the first swing rod 8 and the adjacent parts to rotate and open according to the same steps as above until all the extrusion blocks 17 are in contact with the upper inner wall of the pipe gallery 101. At this time, the fixed base 7 is coaxial with the circular hole. The staff starts the electric wheel 19 and the laser detector 13 through the remote control terminal to move the device backward while measuring the circular hole.

[0043] When the inner circular hole of the pipe gallery 101 is not vibrated sufficiently or the mold is deformed under pressure, the inner wall of the pipe gallery 101 at that location will not be a regular circle (for example, there are some raised parts on the inner wall of the pipe gallery 101). When the fixed base 7 and adjacent components pass through that location, the laser detector 13 detects that the diameter of the circular hole at that location has changed. If the raised part is located on the travel path of one of the electric wheels 19, the laser detector 13 transmits a signal to the remote control terminal. After receiving the signal, the remote control terminal controls all the third electric shafts 18 to rotate a certain angle. The rotation of the third electric shaft 18 drives the adjacent electric wheels 19 to rotate. At this time, the electric wheel 19 drives the fixed base 7 and adjacent components to rotate forward, so that the travel path of the electric wheel 19 is offset from the raised part of the inner wall of the pipe gallery 101, so as to avoid the raised part affecting the stable backward movement of the device. When the electric wheel 19 is offset from the raised part of the inner wall of the pipe gallery 101, the remote control terminal controls the third electric shaft 18 to reset.

[0044] When the protrusion in the pipe gallery 101 is larger, that is, there is always at least one electric wheel 19 that must contact the protrusion, after the remote control terminal receives the signal from the laser detector 13, it controls all the third electric shafts 18 in the same way to drive the adjacent components to rotate, so that the number of electric wheels 19 in contact with the protrusion is reduced to a minimum. Then, when the electric wheel 19 contacts the protrusion, the electric wheel 19 is squeezed by the protrusion, so that the adjacent first swing rod 8 is subjected to a downward swinging force, and the first swing rod 8 transmits the force to the adjacent moving frame 22 through the adjacent second swing rod 9, the adjacent third swing rod 10, the adjacent fourth swing rod 14 and the adjacent fifth swing rod 23, so that the moving frame 22 is subjected to a force to move backward. Because the protrusion in the pipe gallery 101 transmits a hard squeezing force to the adjacent electric wheel 19, the force applied to the moving frame 22 is greater than the elastic force of the adjacent third elastic member 24 and the elastic force of the adjacent limit member 25. The force is applied to the movable frame 22 to press the adjacent limiting member 25 into the prism 12, and the limiting member 25 releases the limiting force on the adjacent movable frame 22. The movable frame 22 moves backward and compresses the adjacent third elastic member 24 to store force, and the adjacent first swing rod 8 and adjacent parts gradually swing downward, so that the adjacent electric wheel 19 can pass through the protrusion. When the first swing rod 8 at this position swings downward, the fixed base 7 is still supported by the first swing rod 8 and adjacent parts at other positions, so the fixed base 7 is still in the axial position of the circular hole, ensuring the accuracy of the laser detector 13 in measuring the inner diameter values ​​of the adjacent circular holes. When the first swing rod 8 and adjacent parts have passed through the protrusion, the movable frame 22 is reset under the elastic force of the adjacent third elastic member 24, driving the adjacent fifth swing rod 23 and the adjacent first swing rod 8 and other parts to reset together, until the upper limit groove of the movable frame 22 is limited and matched with the adjacent limiting member 25 again.

[0045] When the staff finishes measuring the diameter of the circular hole, the staff controls all the electric wheels 19 to reverse through the remote control terminal, takes out the fixed base 7 and adjacent components, and then controls the first electric push rod 11 to reset through the remote control terminal. The reset of the first electric push rod 11 drives the first swing rod 8 and adjacent components to swing and reset. The staff detects the diameters of other circular holes in turn in the same way as above, and records the detected data. When the diameter detection of all circular holes is completed, the staff resets the two extrusion parts 27 by rotating the two second threaded rods 28. The extrusion parts 27 no longer squeeze the adjacent platform 102, and the staff recycles the adjacent components of the fixed block 1 and the fixed base 7 and adjacent components.

[0046] In Example 1, the fixed block 1 and the sliding rod 103 are considered to be fixedly connected, and the staff manually determines the center position of the tunnel 101 by adjusting the positions of the extrusion pieces 27 on both sides. In Example 2, the fixed block 1 and the sliding rod 103 are slidably connected, and the staff automatically determines the center position of the tunnel 101 by controlling the centering mechanism through a remote control terminal.

[0047] Example 2: Based on Example 1, Figure 1-Figure 8 As shown, it also includes a centering mechanism arranged at the rear side of the fixed block 1, and the centering mechanism is used to automatically determine the center of the pipe gallery 101. The centering mechanism includes a fixed column 29 fixed to the rear side of the fixed block 1, and the fixed block 1 is slidably connected to the sliding rod 103. The fixed column 29 is rotatably connected to two rotating rings 30 symmetrically distributed front and back. The two rotating rings 30 are respectively fixed to the fixed column 29 and the fixed block 1 with a fourth elastic member 31, and the fourth elastic member 31 is a torsion spring. The rotating ring 30 is fixed to a hydraulic push rod 32 electrically connected to the remote control terminal. A liquid pressure detection component for monitoring the internal liquid pressure is arranged inside the hydraulic push rod 32, and the liquid pressure detection component is electrically connected to the remote control terminal. The two rotating rings 30 cooperate with adjacent hydraulic push rods 32 to form a shape similar to scissors, and the operating principle of the two is similar to that of scissors. 0 is ball-connected with a second electric push rod 33 electrically connected to the remote control terminal, the telescopic end of the second electric push rod 33 is ball-connected with the lower side of the front rotating ring 30, the upper side of the extrusion piece 27 is fixedly connected with a third electric push rod 34 electrically connected to the remote control terminal, the upper side of the telescopic end of the third electric push rod 34 is fixedly connected with a sliding frame 35, the sliding frame 35 penetrates the adjacent extrusion piece 27, the lower side of the sliding frame 35 is rotatably connected with two rollers 36 symmetrically distributed front and back, the rollers 36 are extruded and matched with the platform 102, the upper side of the fixed block 1 is fixedly connected with a fourth electric push rod 37 electrically connected to the remote control device, the telescopic end of the fourth electric push rod 37 is fixedly connected with a limiting plate 38, the limiting plate 38 is limited by squeezing the sliding rod 103, when the limiting plate 38 is limited by the sliding rod 103, the sliding rod 103 and the fixed block 1 are in a relatively fixed state.

[0048] After the staff has limited the fixed block 1 between the two platforms 102 (that is, after the two extrusion pieces 27 are squeezed and matched with the adjacent platforms 102), the staff first controls the telescopic end of the second electric push rod 33 to extend through the remote control terminal. The extension of the telescopic end of the second electric push rod 33 drives the two rotating rings 30 to rotate, so that the two rotating rings 30 respectively drive the adjacent hydraulic push rods 32 to rotate and open in different directions (refer to the action of opening scissors). When the telescopic end of the second electric push rod 33 is extended to the limit state, the remote control terminal closes the second electric push rod 33. At this time, the angle between the two hydraulic push rods 32 is greater than 90°. The remote control terminal starts the two hydraulic push rods 32 and controls the telescopic end of the fourth electric push rod 37 to move upward by one end. The telescopic end of the fourth electric push rod 37 drives the limit The positioning plate 38 moves upward, and the limiting plate 38 releases the limiting of the adjacent sliding rod 103, so that the fixed block 1 can slide freely relative to the sliding rod 103, and the telescopic ends of the two hydraulic push rods 32 extend synchronously. When the telescopic ends of the two hydraulic push rods 32 contact the inner wall of the pipe gallery 101, the hydraulic push rod 32 that first contacts the inner wall of the pipe gallery 101 will push the fixed column 29, the fixed block 1 and other components to move in the opposite direction, so that the fixed block 1 drives the adjacent components to slide along the adjacent sliding rods 103, until the telescopic ends of the two hydraulic push rods 32 contact the inner wall of the pipe gallery 101. At this time, the telescopic ends of the two hydraulic push rods 32 can no longer extend, and the remote control terminal temporarily closes the two hydraulic push rods 32. At this time, the axis of the fixed column 29 and the center of the pipe gallery 101 are in the same vertical plane.

[0049] After the remote control terminal temporarily closes the two hydraulic push rods 32, the remote control terminal controls the fourth electric push rod 37 to drive the limit plate 38 to reset downward, and the limit plate 38 is squeezed and matched with the sliding rod 103 again to limit the sliding rod 103, and the sliding rod 103 and the fixed block 1 are restored to a relatively fixed state. The staff controls the telescopic end of the second electric push rod 33 to retract through the remote control terminal, driving the two hydraulic push rods 32 to rotate in the closing direction. At this time, if the axis of the fixed column 29 is located on the upper side of the center of the pipe gallery 101, the two hydraulic push rods 32 cannot rotate. If the axis of the fixed column 29 is located on the lower side of the center of the pipe gallery 101, the two hydraulic push rods 32 will no longer contact the inner wall of the pipe gallery 101 after rotation. If the pressure of the telescopic end of the hydraulic push rod 32 changes and increases, it means that the axis of the fixed column 29 is located on the upper side of the center of the pipe gallery 101 (conversely, it means that the axis of the fixed column 29 is located on the lower side of the center of the pipe gallery 101). The remote control terminal detects the pressure change of the liquid in the two hydraulic push rods 32, and judges the positional relationship between the axis of the fixed column 29 and the center of the pipe gallery 101 in real time. Then the remote control terminal controls the telescopic ends of the two third electric push rods 34 to move toward the center of the pipe gallery 101, so that the telescopic ends of the third electric push rods 34 drive the two extrusion members 27 to move together through the sliding frame 35 and the two adjacent rollers 36, and the two extrusion members 27 drive the sliding rod 103 and the fixed block 1 and other components to move toward the center of the pipe gallery 101, so as to gradually adjust the position between the axis of the fixed column 29 and the center of the pipe gallery 101.

[0050] When the remote control terminal controls the movement of the telescopic ends of the two hydraulic push rods 32 to ensure that the liquid pressure in the two hydraulic push rods 32 will not change with the swing of the hydraulic push rods 32, it means that the fixed column 29 has moved to a position that coincides with the center of the circle of the pipeline gallery 101. Then the staff measures the position and diameter of the circular hole and semicircular hole in the pipeline gallery 101 according to the above steps.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
