Description

Technical Field

[0001] The invention relates to the technical field of road tunnel construction, and in particular to a tunnel secondary lining template trolley positioning device. Background Art

[0002] The pouring of tunnel secondary lining concrete requires special equipment: tunnel secondary lining formwork trolley. Like the tunnel shield machine, the tunnel secondary lining formwork trolley is not a general-purpose equipment and needs to be customized by the manufacturer according to the cross-sectional shape and size of the tunnel project before construction. The customized tunnel secondary lining formwork trolley is transported to the construction site in the form of loose parts, assembled on site, and its size is measured and corrected before being moved to the location where the secondary lining needs to be constructed.

[0003] The positioning of the tunnel secondary lining formwork trolley is to move it to the initial support position (pile number) where the secondary lining needs to be poured so that the central axis coincides with the central axis of the tunnel, and the height of the trolley top reaches the design elevation of the secondary lining top (with appropriate reserved clearance height). At present, the main positioning method is the total station. The central axis of the secondary lining formwork trolley is hung with a plumb line. The total station measures whether the plumb line is on the central axis of the tunnel. If not, the horizontal position of the secondary lining formwork trolley is adjusted, and the ground elevation is measured using a total station or a level. The height difference between the tunnel trolley top and the ground is measured using a steel ruler to adjust the elevation position of the secondary lining formwork trolley. Summary of the invention

The hanging wire is connected to the laser plumb ball in a spiral manner at the hanging wire connection point. The battery and the switch button are electrically connected to the laser rangefinder, the Bluetooth communication module, and the data communication processing component. The laser emission port of the laser rangefinder is located at the center of the bottom of the plumb ball. The Bluetooth communication module can receive a Bluetooth signal to control the switch control circuit to be turned on or off so that the laser rangefinder emits a laser beam.

[0007] Preferably, a battery cover is provided outside the battery setting position on the laser plumb ball, and the battery cover is detachable to facilitate battery replacement.

[0008] Preferably, the laser plumb ball is provided with an internal number for distinguishing different laser plumb balls.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] Reference Figure 1-2 During implementation, it includes installing laser vertical probes 4 at both ends of the tunnel secondary lining formwork trolley, reserved holes 13 for ventilation pipes of the tunnel secondary lining formwork trolley, hydraulic system 10 for horizontal adjustment of the secondary lining formwork trolley, hydraulic system 11 for vertical lifting and adjusting of the secondary lining formwork trolley, and using the total station to lay out the tunnel centerline corresponding to the starting and ending pile number points 12 where the secondary lining concrete needs to be poured. The elevation can be measured using a total station or a level.

[0022] Use the temporary track of the trolley to move the secondary lining formwork trolley to a position close to the end point of the layout, install the laser plumb ball 4 at the two end points of the secondary lining formwork trolley, press the power switch 5 of the laser plumb ball, and then automatically emit the laser beam 8. The mobile phone Bluetooth APP can be used to connect the laser plumb ball. Connect the two laser plumb balls, each with an internal number. Set the small pile number direction number to A, and the large pile number direction to B. The number is engraved on the body of the laser plumb ball 4 in numbers.

[0023] Adjust the horizontal position of the hydraulic system 10 and the travel system at both ends of the secondary lining formwork trolley so that the laser beam is aligned with the end point position of the layout. Then use the mobile phone APP to control the two laser beams for distance measurement, and the distance is displayed on the mobile phone APP. The measured distance plus the distance between the hook 1 and the outer side of the top of the secondary lining formwork trolley, plus the elevation of the layout point, calculate the elevation of the top surface of the trolley and compare it with the design height of the top, and use the adjustment trolley vertical lifting hydraulic system 11 to make its top elevation equal to the design elevation. This process requires repeated measurement and adjustment until the error is less than the allowable deviation. To complete the positioning of the tunnel secondary lining formwork trolley.
