Description

Technical Field

[0001] This application relates to the field of tunnel construction, and in particular to a mobile formwork system for power tunnels. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, and power tunnels, among others.

[0003] Chinese Patent Application Publication No. CN107143357A discloses a mobile tunnel lining vehicle. The lining vehicle includes a support frame, with drive devices installed at the bottom of the four corners of the support frame. Multiple rows of support plate devices are arranged side by side along the length of the support frame, and the support plate devices have an arc-shaped structure and are segmented and movable. The support plate devices are movably connected to the support frame through a hydraulic mechanism and support studs. A laser measuring device, a laser lens, and a vibrator are installed on the support plate devices and the support frame. An automatic winding machine is installed on the drive device, which includes front and rear drive devices, which provide moving support for the invention on the guide rail.

[0004] The aforementioned technologies have the following technical drawbacks: the front and rear drive devices can move the entire trolley on the guide rails, thereby enabling the trolley to move along the length of the tunnel. However, the guide rails need to be laid manually in advance along the length of the tunnel, which greatly extends the construction period. Summary of the Invention

[0005] In order to shorten the construction cycle for laying guide rails, this application provides a mobile formwork system for power tunnels.

[0006] The technical solution for the reusable and mobile formwork system for power tunnels provided in this application is as follows:

[0007] A mobile formwork system for power tunnels includes a frame and guide rails located on both sides of the frame. Rollers are rolled on the guide rails on both sides of the frame. A drive device is provided on the frame to drive the rollers to rotate. The guide rails include a first connecting rail and a second connecting rail located on the same straight line. A splicing device is provided between the first and second connecting rails. The splicing device is used to drive the second connecting rail to splice from one end of the first connecting rail to the other end of the first connecting rail, or to drive the first connecting rail to splice from one end of the second connecting rail to the other end of the second connecting rail.

[0008] By adopting the above technical solution and using the first and second connecting rails, when the frame moves from the first connecting rail to the second connecting rail via the drive device, the splicing device can automatically connect the first and second connecting rails. When the frame moves from the second connecting rail to the first connecting rail, the splicing device can automatically connect the second connecting rail to the first connecting rail. This allows for automatic splicing between the first and second connecting rails, eliminating the need for manual laying of guide rails, thus shortening the overall construction cycle and saving significant manpower.

[0009] Optionally, a first connecting plate is provided on one side of the first connecting rail, and a second connecting plate is provided on one side of the second connecting rail. The splicing device includes a drive rod disposed between the first connecting plate and the second connecting plate. One end of the drive rod is hinged to the first connecting plate, and the other end of the drive rod is hinged to the second connecting plate. The first connecting plate is provided with a first drive mechanism for driving the drive rod to rotate at the hinge point or driving the first connecting plate to rotate on the drive rod. The second connecting plate is provided with a second drive mechanism for driving the drive rod to rotate at the hinge point or driving the second connecting plate to rotate on the drive rod.

[0010] By adopting the above technical solution, when it is necessary to drive the first connecting rail to the other end of the second connecting rail, the second driving mechanism drives the driving rod to rotate on the second connecting plate, so that the driving rod drives the first connecting rail to move circumferentially along the second connecting plate. At this time, the first driving mechanism drives the first connecting plate to rotate on the driving rod, so that the first connecting plate drives the first connecting rail to the other end of the second connecting rail. The structure of the driving rod, the first driving mechanism and the second driving mechanism is simple and improves the splicing effect and efficiency of the first connecting rail and the second connecting rail.

[0011] Optionally, one end of the drive rod is fixedly provided with a first connecting shaft that passes through and is rotatably connected to the first connecting plate. The first drive mechanism includes a first rotating gear, a first drive gear, and a first rotating motor. The first rotating gear is sleeved and fixedly connected to the first connecting shaft. The first drive gear is fixedly provided on the drive end of the first rotating motor and meshes with the first rotating gear. The first rotating motor is fixedly provided on the first connecting plate.

[0012] By adopting the above technical solution, when it is necessary to drive the drive rod to rotate, the first rotating motor drives the first drive gear to rotate, which in turn drives the first rotating gear to rotate, thereby causing the first connecting shaft to drive the drive rod to rotate. When it is necessary to drive the first connecting plate to rotate on the drive rod, the first rotating motor drives the first drive gear to rotate, which in turn drives the first connecting plate to rotate on the drive rod. The arrangement of the first rotating gear and the first drive gear can realize the rotation of the drive rod on the first connecting plate and the rotation of the first connecting plate on the drive rod, thus improving the driving effect on the drive rod and the first connecting plate.

[0013] Optionally, the other end of the drive rod is fixedly provided with a second connecting shaft that passes through and is rotatably connected to the second connecting plate. The second drive mechanism includes a second rotating gear, a second drive gear, and a second rotating motor. The second rotating gear is sleeved and fixedly connected to the second connecting shaft. The second drive gear is fixedly provided on the drive end of the second rotating motor and meshes with the second rotating gear. The second rotating motor is fixedly provided on the second connecting plate.

[0014] By adopting the above technical solution, when it is necessary to drive the drive rod to rotate, the second rotation motor drives the second drive gear to rotate, which in turn drives the second rotation gear to rotate, thereby causing the second connecting shaft to drive the drive rod to rotate. When it is necessary to drive the second connecting plate to rotate on the drive rod, the second rotation motor drives the second drive gear to rotate, which in turn drives the second connecting plate to rotate on the drive rod. The arrangement of the second rotation gear and the second drive gear can realize the rotation of the drive rod on the second connecting plate and the rotation of the second connecting plate on the drive rod, thus improving the driving effect on the drive rod and the second connecting plate.

[0015] Optionally, the drive rod includes a first connecting rod and a second connecting rod. The first connecting rod is hinged to a first connecting plate, and the second connecting rod is hinged to a second connecting plate. A lifting rod is vertically arranged between the first and second connecting rods. The first connecting rod and the second connecting rod are slidably arranged on the lifting rod along the height direction of the lifting rod. The first drive mechanism further includes a first lifting mechanism for driving the first connecting rod to move up and down on the lifting rod. The second drive mechanism further includes a second lifting mechanism for driving the second connecting rod to move up and down on the lifting rod.

[0016] By adopting the above technical solution, when it is necessary to drive the drive rod to rotate on the first connecting plate, the second lifting mechanism drives the second connecting rod to rise and fall on the lifting rod, so that the second connecting plate and the second connecting rail are separated from the ground. This facilitates the first rotating gear and the first driving gear to drive the second connecting plate and the second connecting rail to rotate circumferentially along the first connecting plate. When it is necessary to drive the first connecting plate to rotate on the drive rod, the first lifting mechanism drives the first connecting rod to rise and fall on the lifting rod, so that the first connecting plate and the first connecting rail are separated from the ground. At this time, the first rotating gear and the first driving gear can drive the first connecting plate to rotate on the drive rod. The first lifting mechanism further enables the first connecting plate to rotate on the drive rod and the drive rod to rotate on the first connecting plate. The second lifting mechanism further enables the second connecting plate to rotate on the drive rod and the drive rod to rotate on the second connecting plate, further improving the driving effect.

[0017] Optionally, a first lifting groove is formed on the surface of the lifting rod facing the first connecting rod along the height direction of the lifting rod. A first lifting block is fixedly provided on the first lifting rod and slidably connected in the first lifting groove. The first lifting mechanism includes a first screw rod that is rotatably provided in the first lifting groove along the length direction of the first lifting groove. The first lifting block is sleeved and threadedly connected to the first screw rod. A first lifting motor for driving the first screw rod to rotate is fixedly provided in the first lifting groove.

[0018] By adopting the above technical solution, the first lifting motor drives the first screw to rotate. Since the first lifting block is slidably set in the first lifting groove, the first lifting block moves on the first screw, which in turn drives the first connecting rod, the first connecting plate and the first connecting rail to rise and fall. The first screw can be used to fix the first connecting rod, the first connecting plate and the first connecting rail to any position after rising and falling, which improves the driving effect of the first connecting rod, the first connecting plate and the first connecting rail.

[0019] Optionally, a second lifting groove is formed on the surface of the lifting rod facing the second connecting rod along the height direction of the lifting rod. A second lifting block is fixedly installed on the second lifting rod and slidably connected in the second lifting groove. The second lifting mechanism includes a second screw rod that is rotatably installed in the second lifting groove along the length direction of the second lifting groove. The second lifting block is sleeved on and threadedly connected to the second screw rod. A second lifting motor for driving the second screw rod to rotate is fixedly installed in the second lifting groove.

[0020] By adopting the above technical solution, the second lifting motor drives the second screw to rotate. Since the second lifting block is slidably set in the second lifting groove, the second lifting block moves on the second screw, which in turn drives the second connecting rod, the second connecting plate and the second connecting rail to rise and fall. The second screw can be used to fix the second connecting rod, the second connecting plate and the second connecting rail to any position after rising and falling, which improves the driving effect of the second connecting rod, the second connecting plate and the second connecting rail.

[0021] Optionally, both the first connecting rod and the second connecting rod are configured as telescopic structures. The telescopic structure includes a fixed rod and a movable rod that is inserted into and slidably connected within the fixed rod. The fixed rod is provided with an adjustment mechanism for driving the movable rod to move within the fixed rod.

[0022] By adopting the above technical solution, the adjusting mechanism can drive the moving rod to move within the fixed rod, thereby shortening the gap between the first connecting rail and the second connecting rail after splicing and improving the splicing effect between the first connecting rail and the second connecting rail.

[0023] Optionally, the first connecting plate is slidably disposed on the first connecting rail along the length direction of the first connecting rail, and the second connecting plate is slidably disposed on the second connecting rail along the length direction of the second connecting rail. A first moving mechanism for driving the first connecting plate to move on the first connecting rail is disposed on the first connecting rail, and a second moving mechanism for driving the second connecting plate to move on the second connecting rail is disposed on the second connecting rail.

[0024] By adopting the above technical solution, the first connecting plate is moved along the length of the first connecting rail by the first moving mechanism, and the second connecting plate is moved along the length of the second connecting rail by the second moving mechanism, thereby further splicing the first and second connecting rails and improving the movement effect of the frame driving the rollers on the first and second connecting rails.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By adopting the configuration of a first connecting rail and a second connecting rail, when the frame moves from the first connecting rail to the second connecting rail via the drive device, the splicing device can drive the first connecting rail to splice from one end of the second connecting rail to the other end. When the frame moves from the second connecting rail to the first connecting rail again, the splicing device can drive the second connecting rail to splice from one end of the first connecting rail to the other end. This enables automatic splicing between the first and second connecting rails, eliminating the need to lay the guide rails, thus shortening the overall construction cycle and saving a significant amount of manpower by eliminating the need for manual laying of the guide rails.

[0027] 2. When it is necessary to drive the first connecting rail to the other end of the second connecting rail, the second driving mechanism drives the driving rod to rotate on the second connecting plate, so that the driving rod drives the first connecting rail to move circumferentially along the second connecting plate. At this time, the first driving mechanism drives the first connecting plate to rotate on the driving rod, so that the first connecting plate drives the first connecting rail to the other end of the second connecting rail. The structure of the driving rod, the first driving mechanism and the second driving mechanism is simple and improves the splicing effect and efficiency of the first connecting rail and the second connecting rail.

[0028] 3. When it is necessary to drive the drive rod to rotate on the first connecting plate, the second lifting mechanism drives the second connecting rod to rise and fall on the lifting rod, causing the second connecting plate and the second connecting rail to detach from the ground. This facilitates the first rotating gear and the first driving gear to drive the second connecting plate and the second connecting rail to rotate circumferentially along the first connecting plate. When it is necessary to drive the first connecting plate to rotate on the drive rod, the first lifting mechanism drives the first connecting rod to rise and fall on the lifting rod, causing the first connecting plate and the first connecting rail to detach from the ground. At this time, the first rotating gear and the first driving gear can drive the first connecting plate to rotate on the drive rod. The first lifting mechanism further enables the first connecting plate to rotate on the drive rod and the drive rod to rotate on the first connecting plate. The second lifting mechanism further enables the second connecting plate to rotate on the drive rod and the drive rod to rotate on the second connecting plate, further improving the driving effect.

[0043] When it is necessary to rotate the first connecting rod 135 on the first connecting plate 13, the first rotating motor 152 drives the first drive gear 151 to rotate, which in turn drives the first rotating gear 15 to rotate, which in turn drives the first connecting shaft 133 to rotate, which in turn drives the first connecting rod 135 to rotate. When it is necessary to rotate the first connecting plate 13 on the first connecting rod 135, the first lifting motor 154 drives the first screw 153 to rotate, which in turn moves the first lifting block 142 on the first screw 153. This causes the first lifting block 142 to first lift the first connecting plate 13 and the first connecting rail 12 off the ground. At this time, the first rotating motor 152 drives the first drive gear 151 to rotate, which in turn moves circumferentially on the first rotating gear 15, which in turn drives the first connecting plate 13 to rotate, which in turn drives the first connecting rail 12 to rotate.

[0052] Combination Figure 3 and Figure 4 The second connecting rail 121 is provided with a second moving mechanism for driving the second connecting plate 131 to move on the second connecting rail 121.

[0053] The implementation principle of a mobile formwork system for power tunnels according to an embodiment of this application is as follows: When it is necessary to move the first connecting rail 12 to the other end of the second connecting rail 121, the first lifting motor 154 drives the first screw 153 to rotate, thereby causing the first lifting block 142 to lift the first connecting plate 13 and the first connecting rail 12 off the ground. At this time, the second rotating motor 162 drives the second drive gear 161 to rotate, thereby causing the second rotating gear 161 to drive the second connecting shaft 134 to rotate. This causes the second connecting shaft 134 to drive the drive rod 132, the second connecting plate 131, and the second connecting rail 121 to rotate circumferentially along the second connecting plate 131. When the drive rod 132 rotates to the other side of the first connecting plate 13, the first rotating motor 152 drives the first drive rod 132 to rotate circumferentially along the second connecting plate 131. The rotating gear 151 causes the first drive gear 151 to rotate on the first rotating gear 15, which in turn causes the first drive gear 151 to drive the first connecting plate 13 and the first connecting rail 12 to rotate on the first connecting shaft 133. This causes the first connecting plate 13 to drive the first connecting rail 12 towards the other end of the second connecting rail 121 for splicing. By adjusting the electric cylinder 172, the moving rod 171 is moved within the fixed rod 17, causing the insert block 123 to be inserted into the slot 122. This achieves the splicing of the first connecting rail 12 and the second connecting rail 121. When it is necessary to drive the second connecting rail 121 to the other end of the first connecting rail 12, the above steps can be followed. There is no need to lay the guide rail in advance, saving manpower for laying the guide rail and shortening the construction cycle.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
