Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction equipment, in particular to a positioning and correction device for a tunnel lining trolley and a tunnel lining trolley with the positioning and correction device. Background Art

[0002] During the construction of a tunnel's secondary lining, the tunnel lining trolley is a specialized piece of equipment essential for constructing the concrete lining on the tunnel's inner wall. Based on the tunnel construction process sequence and key quality control points, the positioning and calibration of the trolley is fundamental and crucial for ensuring the quality and clearance of the tunnel's secondary lining.

[0003] See also Figure 1 Existing tunnel lining trolleys are all equipped with center point markers at several locations such as the arch template 13 and the gantry 14, which are used by surveyors to calibrate the positioning of the tunnel lining trolley as a whole and the tunnel centerline 12 through multiple center lines. The main steps of the positioning and correction operation are as follows: 1. The surveyor measures and stakes out the center point on the ground; 2. The work team lays the tunnel lining trolley running rails 15 and runs the tunnel lining trolley. This process has high precision requirements for the lateral position of the laying of the rails 15. At the same time, after the tunnel lining trolley has finished running, the workers need to use a plumb bob to check the center line of the tunnel lining trolley. If there is a large deviation, the tunnel lining trolley needs to be returned, the rails 15 need to be re-laid, and the process needs to be repeated; 3. The surveyor measures and adjusts the height and horizontal accuracy of the tunnel lining trolley's beam 16; 4. The surveyor measures and adjusts the center of the tunnel lining trolley's beam 16; 5. The surveyor measures and corrects the center and elevation of the tunnel lining trolley's formwork 13; 6. The surveyor measures and adjusts the side formwork of the tunnel lining trolley's formwork 13; 7. Lock all the support systems of the tunnel lining trolley and proceed to the next process, which is to close the tunnel lining trolley's formwork 13 and prepare for pouring.

[0004] The existing positioning and correction operations of the tunnel lining trolley only use the plumb bob to check the center point, and then the surveyors repeatedly adjust the crossbeam 16, gantry 14 main beam and other structures of the tunnel lining trolley. The laying of the rails 15 that guide the tunnel lining trolley is not positioned and corrected. As a result, the positioning and correction process of the tunnel lining trolley before construction is cumbersome, time-consuming and low-precision. Summary of the Invention

[0016] In order to achieve the second object of the present invention, the present invention provides a tunnel lining trolley, including the positioning and correction device for the tunnel lining trolley mentioned above.

[0017] During the tunnel secondary lining construction process, the second suspension of the positioning and correction device is fixed to the top frame of the gantry, and the first suspension of the positioning and correction device is fixed to the bracket of the gantry, with the centerline positions of the second and first suspensions corresponding to the centerline position of the gantry. Subsequently, the second laser emitter of the second measuring mechanism on the second suspension and the first laser emitter of the first measuring mechanism on the first suspension are activated. Multiple second indicator lines emitted by the second laser emitter are reflected by the fourth spherical reflector and then emitted outward from the side of the second housing away from the second suspension. Multiple second indicator lines are emitted radially outward in a circular pattern from a fourth indicator section of the second housing. Since the fourth indicator section is located at the centerline of the second suspension and is arranged perpendicular to the longitudinal extension of the second suspension, the fourth indicator section is aligned with the calibrated centerline of the tunnel during installation of the second suspension. Therefore, the laser lines emitted from the fourth indicator section form a tunnel centerline indicator line on the tunnel arch. A horizontal hydraulic cylinder can be used to control the horizontal movement of the crossbeam to adjust the centerline position of the formwork to align with it. At the same time, the multiple first indicator lines emitted by the first laser emitter are reflected by the first spherical reflector, the second spherical reflector, and the third spherical reflector, and then emitted outward on the side of the first shell away from the first suspension. The first spherical reflector causes the multiple first indicator lines to be emitted outward in a circular radial pattern on the first indicator section of the first shell. Since the first indicator section and the fourth indicator section are located on the same plane, the first indicator section is adjusted to be aligned with the tunnel calibration center line when the first suspension is installed. Therefore, the laser line emitted from the first indicator section forms a tunnel center line indicator line on the ground of the tunnel. When the laser line emitted from the first indicator section is aligned with the tunnel calibration center line, it indicates that the gantry is The frame is located in a construction position, and the second spherical reflector causes the multiple first indicator lines to be radially emitted outward in a circular manner on the second indicator section of the first shell, and the third spherical reflector causes the multiple first indicator lines to be radially emitted outward in a circular manner on the third indicator section of the first shell, and the third indicator section and the second indicator section are symmetrically arranged with respect to the first indicator section, so that the laser lines emitted from the second indicator section and the third indicator section are respectively directed to the two longitudinal rails and form longitudinal rail laying edge lines for indicating the subsequent laying positions of the longitudinal rails and guiding the laying of the longitudinal rails, thereby avoiding large deviations of the longitudinal rails and requiring the tunnel lining trolley to be returned and re-laid.

[0018] The present invention forms a tunnel centerline indicator line on the top arch of the tunnel by emitting a laser line from the fourth indicator section, forms a tunnel centerline indicator line on the ground of the tunnel by emitting a laser line from the first indicator section, and forms a tunnel centerline indicator line on the ground of the tunnel by emitting laser lines from the second indicator section and the third indicator section respectively toward the two longitudinal rails and forming the longitudinal rail laying edge lines, so that the tunnel lining trolley of the present invention can realize real-time indication in the direction of the template centerline, the ground walking centerline and the rail laying edge line, improve the positioning and correction accuracy of the tunnel lining trolley during the construction process, ensure the quality of tunnel construction, and greatly reduce the operating process time of the surveying personnel and the work team repeatedly adjusting the tunnel lining trolley, thereby realizing the fast, efficient and precise positioning and correction process operation of the tunnel lining trolley and shortening the process time. At the same time, the positioning and correction device of the tunnel lining trolley of the present invention is simple and convenient to operate, has high measurement accuracy, can work continuously for a long time, has low equipment cost investment, and has significant use effect, greatly reducing the labor intensity of the surveying personnel, and the implementation effect at the tunnel construction site is extremely significant.

[0025] See also Figures 2 to 5This embodiment discloses a tunnel lining trolley, comprising a gantry 14, a crossbeam 16, two longitudinal rails 15, a vertical cylinder 111, a support cylinder 110, a horizontal cylinder 19, a lifting cylinder 18, a template 13, and a positioning and correction device 2. The crossbeam 16 is vertically positioned above the gantry 14. The horizontal cylinder 19 and the lifting cylinder 18 are respectively mounted on the top frame 141 of the gantry 14. The horizontal cylinder 19 is used to control the horizontal movement of the crossbeam 16, while the lifting cylinder 18 is used to control the vertical movement of the crossbeam 16. The template 13 is arranged in an arc shape outside the gantry 14 and crossbeam 16. The template 13 and crossbeam 16 are connected by columns 17, and the template 13 is connected to the support columns 143 of the gantry 14 by the supporting cylinder 110. The longitudinal rails 15 extend in the longitudinal direction of the tunnel 11. The two support columns 143 of the gantry 14 are slidably arranged on the two longitudinal rails 15 respectively. The vertical cylinder 111 is arranged at one end of the support column 143 of the gantry 14 away from the top frame 141 and is used to control the movement of the support column 143 in the vertical direction.

[0026] Specifically, the positioning and correction device 2 of this embodiment includes a second suspension 21, a first suspension 23, a support frame 22, a second measuring mechanism and a first measuring mechanism. The support frame 22 is connected between the center line positions of the second suspension 21 and the first suspension 23, and an "I" shape is formed between the second suspension 21, the support frame 22 and the first suspension 23. Among them, the second measuring mechanism is arranged at the midline position of the second suspension 21, and the second measuring mechanism includes a second shell 24, a fourth spherical reflector (not marked) and a second laser emitter (not marked). The second shell 24 is arranged in a hollow sphere, the second laser emitter is located inside the second shell 24, and the fourth spherical reflector is arranged on the inner spherical wall of the second shell 24. The fourth spherical reflector reflects the multiple second indication lines 242 emitted by the second laser emitter and emits them outward through the side of the second shell 24 away from the second suspension 21. The multiple second indication lines 242 are radially emitted outward in a circular pattern on the fourth indication section 241 of the second shell 24. The fourth indication section 241 is located at the midline position of the second suspension 21 and is arranged perpendicular to the length extension direction of the second suspension 21. The first measuring mechanism is mounted on the first suspension 23 and includes a first housing 25, a first spherical reflector 255, a second spherical reflector (not labeled), a third spherical reflector (not labeled), and a first laser emitter 254. The first housing 25 is a hollow sphere, with the first laser emitter 254 located within the interior. The first spherical reflector 255, the second spherical reflector, and the third spherical reflector are respectively mounted on the inner wall of the first housing 25. Multiple first indicator lines emitted by the first laser emitter 254 are reflected by the first spherical reflector 255, the second spherical reflector, and the third spherical reflector, and then emitted outward from a side of the first housing 25 away from the first suspension 23. The first spherical reflector 255 causes the multiple first indicator lines to be radially emitted outward in a circular pattern on a first indicator section 251 of the first housing 25. The first indicator section 251 and the fourth indicator section 241 are located on the same plane. The second spherical reflector causes the plurality of first indication lines to be radially emitted outward in a circular pattern on the second indication section 252 of the first shell 25, and the third spherical reflector causes the plurality of first indication lines to be radially emitted outward in a circular pattern on the third indication section 253 of the first shell 25, and the third indication section 253 and the second indication section 252 are symmetrically arranged with respect to the first indication section 251.

[0027] During the secondary lining construction process of tunnel 11, the second suspension 21 of the positioning and correction device 2 is fixed on the top frame 141 of the gantry 14, and the first suspension 23 of the positioning and correction device 2 is fixed on the bracket of the gantry 14, and the centerline position of the second suspension 21 and the first suspension 23 corresponds to the centerline position of the gantry 14. Then, the second laser emitter of the second measuring mechanism on the second suspension 21 and the first laser emitter 254 of the first measuring mechanism on the first suspension 23 are turned on. The multiple second indicator lines 242 emitted by the second laser emitter are reflected by the fourth spherical reflector and then emitted outward from the side of the second shell 24 away from the second suspension 21. The multiple second indicator lines 242 are emitted outward in a circular radial pattern on the fourth indicator section 241 of the second shell 24. Since the fourth indicator section 241 is located at the center line position of the second suspension 21 and is arranged perpendicular to the length extension direction of the second suspension 21, the fourth indicator section 241 is adjusted to align with the tunnel demarcated center line 12 when the second suspension 21 is installed. Therefore, the laser line emitted from the fourth indicator section 241 forms a tunnel center line indicator line 242 on the top arch of the tunnel 11. The horizontal cylinder 19 can be used to control the horizontal movement of the crossbeam 16 to adjust the center line position of the template 13 to align with it. At the same time, the multiple first indication lines emitted by the first laser emitter 254 are reflected by the first spherical reflector 255, the second spherical reflector, and the third spherical reflector, and then emitted outward on the side of the first housing 25 away from the first suspension 23. The first spherical reflector 255 causes the multiple first indication lines to be emitted outward in a circular radial pattern on the first indication section 251 of the first housing 25. Since the first indication section 251 and the fourth indication section 241 are located on the same plane, the first indication section 251 is adjusted to be aligned with the tunnel demarcated center line 12 when the first suspension 23 is installed. Therefore, the laser line emitted from the first indication section 251 forms a tunnel center line indication line on the ground of the tunnel 11. Then, when the first indication section 251 is aligned with the tunnel center line 12, the tunnel center line 12 is aligned with the tunnel center line 12. When the emitted laser line is aligned with the tunnel demarcated center line 12, it indicates that the gantry 14 is in a construction position, and the second spherical reflector causes multiple first indication lines to be emitted radially outward in a circular pattern on the second indication section 252 of the first shell 25, and the third spherical reflector causes multiple first indication lines to be emitted radially outward in a circular pattern on the third indication section 253 of the first shell 25. The third indication section 253 and the second indication section 252 are symmetrically arranged with respect to the first indication section 251, so that the laser lines emitted from the second indication section 252 and the third indication section 253 are respectively directed toward the two longitudinal rails 15 and form the laying edge lines of the longitudinal rails 15, which are used to indicate the laying positions of subsequent longitudinal rails 15.

[0028] In this embodiment, the laser line emitted from the fourth indicating section 241 forms a tunnel centerline indicating line 242 on the top arch of the tunnel 11, the laser line emitted from the first indicating section 251 forms a tunnel centerline indicating line on the ground surface of the tunnel 11, and the laser lines emitted from the second indicating section 252 and the third indicating section 253 are respectively directed toward the two longitudinal rails 15 and form the laying edge lines of the longitudinal rails 15. This allows the tunnel lining trolley of this embodiment to provide real-time indication of the centerline of the template 13, the ground running centerline, and the rail laying edge lines. This improves the positioning and correction accuracy of the tunnel lining trolley during construction, ensures the construction quality of the tunnel 11, and significantly reduces the operating time required by surveyors and work teams to repeatedly adjust the tunnel lining trolley. This achieves fast, efficient, and precise positioning and correction of the tunnel lining trolley, shortening the process time. Furthermore, the positioning and correction device 2 for the tunnel lining trolley of this embodiment is simple and convenient to operate, has high measurement accuracy, can operate continuously for a long time, has low equipment cost investment, and has significant performance, greatly reducing the labor intensity of surveyors and achieving extremely significant implementation results at tunnel construction sites.

[0029] In addition, the positioning and correction device 2 of this embodiment also includes a laser rangefinder 28, which is arranged on the side of the first suspension 23 away from the second suspension 21. The laser rangefinder 28 measures the distance between the first suspension 23 and the ground of the tunnel 11 in real time, enabling the tunnel lining trolley to immediately measure and adjust the overall trolley height after completing its travel. That is, the vertical cylinder 111 controls the support column 143 of the gantry 14 to move in the vertical direction for adjustment, thereby further improving the positioning and correction accuracy of the tunnel lining trolley during construction. Specifically, in this embodiment, the angle between the second indicating section 252 and the first indicating section 251 is less than 90°, and the fourth indicating section 241 is arranged parallel to the width extension direction of the second suspension 21, thereby improving the working reliability of the second measuring mechanism and the first measuring mechanism.

[0030] In addition, in this embodiment, the first suspension 23 is provided with a fixing sleeve 210 having a through-hole (not shown) extending therethrough. The first housing 25 is provided with a connecting rod 29 that can be inserted into the through-hole. The threaded end of a fixing bolt 211 is threadedly connected to the peripheral wall of the fixing sleeve 210 and passes through the peripheral wall of the fixing sleeve 210 to press against the outer peripheral wall of the connecting rod 29, thereby enabling the first housing 25 to be removably mounted on the first suspension 23. Alternatively, the connecting rod 29 may be provided with external threads, and the through-hole may be provided with internal threads that mate with the external threads of the connecting rod 29, thereby enabling the first housing 25 to be removably mounted on the first suspension 23.

[0031] To enhance horizontal leveling accuracy, in this embodiment, the second suspension 21 is equipped with a first electronic level 26 for determining the levelness of the second suspension 21. The first suspension 23 is equipped with a second electronic level 27 for determining the levelness of the first suspension 23. Since the second suspension 21 is fixed to the top frame 141 of the gantry 14, and the first suspension 23 is fixed to the bracket of the gantry 14, the first and second electronic levels 26, 27 monitor the levelness of the gantry 14 in real time, improving the operating accuracy of the gantry 14. Specifically, in this embodiment, there are two first electronic levels 26, symmetrically positioned at either end of the second suspension 21 about the centerline. There are also two second electronic levels 27, symmetrically positioned at either end of the first suspension 23 about the centerline.

[0032] The above embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles of the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
