Description

Technical Field

[0001] This invention relates to the field of measurement and smoothing system technology, specifically to an automated measurement and smoothing system for subway tunnel base plates. Background Technology

[0002] The construction of the base plate of a subway tunnel is a critical process in the construction of subway tunnel lines. Its flatness and plane height affect the quality of subsequent processes and the amount of adjustment work. Therefore, ensuring that the flatness and elevation accuracy of the base plate meet the design requirements is a key indicator to ensure the progress of the project and the quality of subsequent construction.

[0003] The construction plane and elevation accuracy of the base plate generally require a certain width to ensure symmetry on both sides of the design centerline, and the elevation accuracy should be a certain value lower than the design elevation. In actual construction surveying, the centerline of the line is measured first. Then, the line is divided into multiple sections. Two points are measured at a certain distance from the centerline on both sides of each section. Next, holes are drilled at the four points, four steel bars are inserted, and the height is measured. Marks are tied or drawn at the required plane height as indicators for grouting and smoothing. Finally, the surface is manually smoothed according to the marks.

[0004] This process is relatively mature, but the steps are complex and manual processing relies on the individual rigor and skill level of the workers. The final result often has unevenness, with an error of about 1 cm. The error is even greater in the superelevation section of the curve, and may even require later correction or rework. Therefore, the research and development of a mechanically automated base plate measurement and smoothing system is of great practical significance. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an automated system for measuring and smoothing subway tunnel base plates. Existing technologies involve manual smoothing, which is complex to operate and relies on the individual worker's meticulousness and skill level. Uneven smoothing results often require remedial measures or rework. Using automated mechanical equipment not only saves labor and reduces the workload of workers, but also improves smoothing accuracy and efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automated subway tunnel base plate measurement and smoothing system, comprising an end face walking device, a cross-section measuring device, and a smoothing device;

[0009] The end face traveling device is connected to the top of the cross-section measuring device, and the end face traveling device is also connected to the top of the smoothing device.

[0010] The end face walking device includes an end face walking frame, and the bottom of the end face walking frame is provided with rollers;

[0011] An angle box is installed on the end face walking frame. Emergency stop buttons are provided at both the front and rear ends of the end face walking frame. The end face walking frame is bolted to the bottom of the audible and visual alarm. The end face walking frame is fixed to the rear end of the driver control box. The driver control box is a control box for installing the cross-section measurement module and the lifting electric cylinder module, etc. The whole assembly is installed together, which is both beautiful and space-saving.

[0012] A battery is installed at the left end of the end face walking frame. This battery powers the device, working in conjunction with the drive control box to control the cross-section measuring device and the smoothing device. An operating handle is located at the bottom of the drive control box. This handle controls the forward and backward movement and different speeds of the end face walking frame. It is a wireless operating handle, convenient for on-site operators, who do not need to closely follow the equipment. A control panel is connected to the bottom of the operating handle. This control panel collects and sets various measurement data, controls the movements of the cross-section measuring device and the smoothing device, and allows users to view equipment status, battery level, etc. It is mounted on the same side as the seat and operating handle for easy operation. The end face walking frame is fixed to the bottom of the seat. The seat is provided for operators to access the control panel and also allows for rest, preventing prolonged standing.

[0013] An end-face walking control cabinet is embedded in the right end of the end-face walking frame. The end-face walking control cabinet contains electrical components such as a drive battery and a driver, which are used to control the end-face walking frame. The device is equipped with two sets of batteries and control devices. One set is used to control the end-face walking frame, and the other set is used to control the cross-section measuring device and the leveling device. Due to the limited number of voltage plugs on site and the long working distance each time, battery drive is used to ensure continuous operation. Because the overall structure of the equipment is large, in order to save battery capacity and volume, it is driven by two sets of structures, which are installed on both sides of the end-face walking frame. This also balances the weight on both sides and prevents the whole machine from tilting due to excessive weight on one side. A prism is installed on the end-face walking frame.

[0014] Preferably, the cross-section measuring device includes a cable chain, a linear module, a connecting plate, and a laser. The number of connecting plates is greater than two sets, and the device is fixed to the end face walking frame through multiple sets of connecting plates. There are three sets of linear modules. Each set of linear modules has a laser installed on its slider through a connecting block. This allows for the layout of the reinforcing bars before leveling the base plate and the measurement of the cross-section accuracy after leveling. Each set of linear modules is equipped with a cable chain that can thread the laser cable through it, ensuring that the laser cable is pulled and protected when the slider on the linear module reciprocates.

[0015] Preferably, the smoothing device includes a vibratory mounting plate, a vibratory motor, a smoothing plate, a smoothing plate connecting plate, a linear bearing, a hollow shaft, a lifting cylinder fixing plate, a lifting cylinder connecting plate, a lifting cylinder, a lifting cylinder connecting block, a bearing connecting block, an auxiliary roller structure, a main roller structure, and a main roller connecting plate. The lifting cylinder connecting plate is fixed to the bottom of the end face traveling frame. One side of the lifting cylinder is connected to the lifting cylinder fixing plate, and the other side is connected to the lifting cylinder connecting block. Because the system is large in size, there is a risk of structural instability when the two lifting cylinders are fixed to the end face traveling device. Therefore, a lifting cylinder connecting plate is used to stabilize the structure of the two lifting cylinders. A bearing is used to connect the lifting cylinder connecting block and the bearing connecting block. This bearing structure can rotate left and right, so that the structure can operate normally when the two lifting cylinders do not descend at the same time or when a height difference is required. The main roller connecting plate is connected to the bearing connecting block. The main roller structure is connected below the main roller connecting plate, and the auxiliary roller structure is connected to the rear side. The vibratory motor and the smoothing plate are connected to the rear side.

[0016] Preferably, the vibration mounting plate, vibration motor, smearing plate, and smearing plate connecting plate together constitute a smearing structure. There are two sets of the smearing structure. The two sets of smearing structures are vertically connected by two lifting electric cylinders to handle the rising and falling, and horizontally connected to a hollow shaft via a linear bearing.

[0017] Preferably, the vibration motor is mounted on a vibration mounting plate and connected to the main roller structure through the vibration mounting plate.

[0018] Preferably, the vibration motor and the vibration mounting plate are fixed with a waist-shaped hole, which ensures that the vibration motor drives the vibration motor mounting plate to vibrate up and down when it vibrates, with little impact on the vibration motor connecting plate, thereby reducing the vibration impact on the entire system. After the vibration motor vibrates, a trowel plate is placed behind it to smooth the cement.

[0019] Preferably, the smoothing plate is connected to the main roller connecting plate via a smoothing connecting plate to prevent the vibration of the vibrating motor from affecting it. A reinforcing rib structure is used at the connection point of the smoothing connecting plate to improve the connection strength.

[0020] Preferably, the auxiliary roller structure includes a main roller connecting block, a main roller connecting shaft, a main roller, and a main roller scraper. The main roller is connected to the main roller connecting block via the main roller connecting shaft. A bearing is installed on the inner side of the main roller connecting block to drive the main roller to move. The main roller connecting block and the main roller connecting plate are connected to form an integral structure. The main roller scraper is installed on the left and right sides of the main roller connecting block. The function of the main roller scraper is to scrape off the cement driven by the main roller during its movement, preventing it from sticking to the main roller over time and affecting its movement.

[0021] Preferably, the main roller structure includes a linear module connecting plate, a secondary roller connecting block, a secondary roller connecting shaft, a secondary roller connecting plate, a linear module, a secondary roller, and a secondary roller scraper. One side of the linear module connecting plate is fixed to the main roller connecting plate, and the linear module is installed on the other side. The linear module is fixed to the secondary roller connecting plate via a slider. The secondary roller connecting plate has secondary roller connecting blocks on both sides, which are fixed to the secondary roller via bearings and the secondary roller connecting shaft. The function of the secondary roller scraper is to scrape off cement carried by the secondary roller during its movement, preventing it from adhering to the secondary roller over time and affecting its movement. Because the main roller is a fixed structure, and the width of the base plate varies in different tunnels, the secondary roller needs a width adjustment function to cover the overall width of the base plate. Therefore, one main roller structure connects to two secondary roller structures. The installation of the linear module and the motor installation are determined according to actual needs.

[0024] This invention provides an automated system for measuring and smoothing the base plate of a subway tunnel. It offers the following advantages: The planar position of the equipment is determined through the collaborative measurement of four prisms and a total station, identifying the first cross-section position. Elevation difference measurement is achieved through the laser movement of the cross-section measuring device. All measurement data is aggregated on the control panel. By setting various engineering parameters, the required point coordinates and elevations are calculated. Then, commands are issued to control the raising and lowering of the laser layout and smoothing device.

During the movement of the end-face traveling frame, the smoothing device is driven to smooth the base plate. The accuracy of the smoothed surface can be measured using the cross-section measuring device. Attached Figure Description

[0033] Please see Figure 1 The present invention provides a technical solution for an automated subway tunnel base plate measurement and smoothing system: an automated subway tunnel base plate measurement and smoothing system includes an end face walking device 1, a cross section measuring device 2, and a smoothing device 3; the end face walking device 1 is connected to the top of the cross section measuring device 2, and the end face walking device 1 is connected to the top of the smoothing device 3.

[0034] Please see Figure 2This invention provides a technical solution for an automated subway tunnel base plate measurement and leveling system: An automated subway tunnel base plate measurement and leveling system includes an end-face walking device 1 comprising an end-face walking frame 11, with rollers at the bottom of the end-face walking frame 11 that travel on guide rails on both sides of the subway tunnel; an tilt box 12 is installed on the end-face walking frame 11 to monitor the current tilt status of the equipment; emergency stop buttons 13 are installed at both ends of the end-face walking frame 11, which, when pressed in an emergency, disengage the equipment to stop it; for ease of operation, buttons 13 are installed on both sides of the equipment; the end-face walking frame 11 is connected to an audible and visual alarm 14. The bottom is bolted together. The audible and visual alarm 14 can simulate different working conditions to warn on-site workers and prevent injuries. For clear visibility, it is installed on both sides of the equipment. The end-face walking frame 11 is fixed to the rear end of the drive control box 15. The drive control box 15 houses the cross-section measurement module 2 and the lifting cylinder module, etc., and is installed as a whole, which is both aesthetically pleasing and space-saving. A battery 16 is installed on the left end of the end-face walking frame 11. The battery 16 provides power and works with the drive control box 15 to control the cross-section measurement device 2 and the leveling device 3. An operating handle 17 is located at the bottom of the drive control box 15. The operating handle 17 can... The end-face walking frame 11 is controlled by a wireless operating handle to move forward, backward, and at different speeds, facilitating operation by on-site personnel who do not need to closely follow the equipment. A control panel 18 is connected to the bottom of the operating handle 17. The control panel 18 can collect and set various measurement data, control the movements of the cross-section measuring device 2 and the smoothing device 3, and also display equipment status and battery level. It is mounted on the same side as the seat 19 and operating handle 17 for easy operation. The end-face walking frame 11 is fixed to the bottom of the seat 19, which provides a place for operators to operate the control panel and also allows for rest, preventing prolonged standing. The right end is embedded with an end face travel control cabinet 110, which contains electrical components such as a drive battery and a driver to control the end face travel frame. The device is equipped with two sets of batteries and control devices: one set to control the end face travel frame and the other set to control the cross-section measuring device and the leveling device. Due to the limited number of 220V voltage plugs on site and the long working distance each time, battery drive is used to ensure continuous operation. Because the overall structure of the equipment is large, in order to save battery capacity and volume, it is driven by two sets of structures, which are installed on both sides of the end face travel frame. This also balances the weight on both sides and prevents the whole machine from tilting due to excessive weight on one side.

[0035] Please see Figure 3This invention provides a technical solution for an automated subway tunnel base plate measurement and smoothing system: An automated subway tunnel base plate measurement and smoothing system includes a cross-section measuring device 2 comprising a drag chain 21, linear modules 22, connecting plates 23, and a laser 24. The number of connecting plates 23 is greater than two sets, and the system is fixed to the end-face walking frame 11 via multiple sets of connecting plates 23. Three sets of linear modules 22 are provided. Each set of linear modules 22 has a laser 24 mounted on its slider via connecting blocks, enabling rebar layout before smoothing and cross-sectional accuracy measurement of the base plate after smoothing. A drag chain 21 is installed next to each set of linear modules 22, through which the laser cable can be threaded, ensuring that the laser cable is pulled and protected during the reciprocating motion of the slider on the linear module 22. Because the base plate span is large and there are many test points, three linear modules 22 are used to ensure that each position can be detected. Figure 3 The arrangement shown is used to achieve the measurement purpose. In addition, it is necessary to ensure that there is no obstruction between the vertical direction of the laser 24 and the base plate to prevent affecting the laser detection.

[0036] Please see Figures 4-6This invention provides a technical solution for an automated subway tunnel base plate measurement and smoothing system: An automated subway tunnel base plate measurement and smoothing system, the smoothing device 3 includes a vibration mounting plate 31, a vibration motor 32, a smoothing plate 33, a smoothing plate connecting plate 34, a linear bearing 35, a hollow shaft 36, a lifting cylinder fixing plate 37, a lifting cylinder connecting plate 38, a lifting cylinder 39, a lifting cylinder connecting block 3a, a bearing connecting block 3b, a secondary roller structure 3c, a main roller structure 3d, and a main roller connecting plate 3e. The lifting cylinder connecting plate 38 is fixed to the bottom of the end face traveling frame 11, and the lifting cylinder... One side of the lifting cylinder 39 is connected to the lifting cylinder fixing plate 37, and the other side is connected to the lifting cylinder connecting block 3a. Because the system is relatively large, there is concern about structural instability when fixing the two lifting cylinders 39 to the end face traveling device 1. Therefore, a lifting cylinder connecting plate 38 is used to stabilize the structure of the two lifting cylinders 39. A bearing connects the lifting cylinder connecting block 3a and the bearing connecting block 3b. This bearing structure can rotate left and right, ensuring normal operation of the structure when the two lifting cylinders 39 do not descend simultaneously or when a height difference is required. The main roller connecting plate 3e is connected to the bearing connecting block 3b, and the main roller connecting... Below plate 3e is a main roller structure 3d, and behind it is a secondary roller structure 3c. Behind the 3c are a vibrating motor 32 and a smoothing plate 33. The vibrating mounting plate 31, vibrating motor 32, smoothing plate 33, and smoothing plate connecting plate 34 together form a smoothing structure. Two sets of smoothing structures are provided. Vertically, two lifting cylinders 39 are used for raising and lowering the two sets of smoothing structures. Horizontally, they are connected to a hollow shaft 36 via a linear bearing 35. One side of the hollow shaft 36 is fixed, and the other side moves, ensuring the connection of the overall structure even when the bearing structure rotates left and right. Because the length of the hollow connecting shaft is limited, the two... The height difference of the lifting cylinder 39 is also within a range and cannot be raised or lowered arbitrarily. The vibration motor 32 is installed on the vibration mounting plate 31 and is connected to the main roller structure 3d through the vibration mounting plate 31. There is a waist-shaped hole at the fixed position of the vibration motor 32 and the vibration mounting plate 31 to ensure that the vibration motor drives the vibration motor mounting plate to vibrate up and down when it vibrates, which has little impact on the vibration motor connecting plate, thereby reducing the vibration impact on the entire system. After the vibration motor vibrates, there is a trowel plate behind it to smooth the cement. The trowel plate 33 is connected to the main roller connecting plate 3e through the smoothing connecting plate 34 to prevent the vibration of the vibration motor from affecting it.The joint of the smoothing connecting plate uses a reinforcing rib structure to improve the connection strength. The auxiliary roller structure 3c includes a main roller connecting block 3c1, a main roller connecting shaft 3c2, a main roller 3c3, and a main roller scraper 3c4. The main roller 3c3 is connected to the main roller connecting block 3c1 through the main roller connecting shaft 3c2. Bearings are installed on the inner side of the main roller connecting block 3c1 to drive the movement of the main roller 3c3. The main roller connecting block 3c1 and the main roller connecting plate 3e are connected to form an integral structure. The main roller scraper 3c4 is installed on the left and right sides of the main roller connecting block 3c1. The function of the main roller scraper 3c4 is to scrape off the cement driven by the main roller 3c3 during its movement, preventing it from sticking to the main roller 3c3 over time and affecting its operation. The main roller structure 3d includes a linear module connecting plate 3d1, a secondary roller connecting block 3d2, a secondary roller connecting shaft 3d3, a secondary roller connecting plate 3d4, a linear module 3d5, a secondary roller 3d6, and a secondary roller scraper 3d7. One side of the linear module connecting plate 3d1 is fixed to the main roller connecting plate 3e, and the linear module 3d5 is installed on the other side. The linear module 3d5 is fixed to the secondary roller connecting plate 3d4 via a slider. The secondary roller connecting plate 3d4 has secondary roller connecting blocks 3d2 on both sides, which are fixed to the secondary roller 3d6 via bearings and the secondary roller connecting shaft 3d3. The function of the secondary roller scraper 3d7 is to scrape off the cement driven by the secondary roller 3d6 during its movement, preventing it from sticking to the secondary roller 3d6 over time and affecting its movement. Because the main roller 3c3 is a fixed structure, and the width of the base plate varies in different tunnels, the auxiliary roller 3d6 needs to have a width adjustment function to cover the overall width of the base plate. Therefore, one set of main roller structure 3d is connected to two sets of auxiliary roller structures 3c. The installation of the linear module 3d5 is determined according to actual needs. The total station or surveying robot is set up based on CPIII to establish the measurement benchmark.

[0037] After the equipment is hoisted onto the subway tunnel running track, its planar position needs to be determined by the cooperation of four prisms 111 and a total station to determine the position of the first cross-section. The elevation difference is measured by moving the laser 24 of the cross-section measuring device 2. All measurement data are collected in the control panel 18. By setting various engineering parameters, the required point coordinates and elevations are calculated. Then, instructions are issued to control the laser 24 to lay out and the leveling device 3 to rise and fall. After the leveling device 3 descends to a certain distance, the straight module 3d5 of 3d6 is adjusted to move to a certain position. During the movement of the end face walking frame 11, the leveling device 3 drives the base plate to level. The accuracy after leveling can be measured by the cross-section measuring device 2.

[0038] The control method of this invention is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0039] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
