Description

Technical Field

[0001] This utility model relates to the technical field of tunnel arch construction flatness measurement device, specifically a tunnel arch construction flatness measurement device. Background Technology

[0002] The invert arch is one of the main components of a tunnel structure, serving as its foundation. It effectively transfers the pressure from the upper strata to the underground via the tunnel sidewalls or road surface loads, while also resisting the reaction forces from the lower strata. However, during invert arch construction flatness measurement, uneven ground often causes the device to tilt horizontally, leading to inaccurate measurement results. To address these issues, a horizontally adjustable invert arch construction flatness measurement device is needed. Utility Model Content

[0003] The purpose of this invention is to provide a device for measuring the flatness of tunnel invert arch construction, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for measuring the flatness of a tunnel invert arch construction includes an invert arch body. Rollers are installed at the bottom inner side of the invert arch body. A supporting base plate is installed on the top of the rollers. First telescopic rods are installed at both ends of the supporting base plate. An operating panel is installed on the top of the first telescopic rods. A control button is embedded on the longer outer side of the operating panel. First connecting frames are installed on the narrower outer sides of the operating panel. A second telescopic rod is installed at the end of the first connecting frame away from the operating panel. A measuring template is installed on the outer side of the second telescopic rod away from the first connecting frame. First scrapers are installed on the longer outer sides of the measuring template. A connecting block is installed on the top of the measuring template. A level sensor is installed on the top of the operating panel. A supporting cylinder is installed on the top of the operating panel. A supporting pipe is installed on the top of the supporting cylinder. A supporting plate is installed on the top of the supporting pipe. Second connecting members are installed on the narrower outer sides of the top of the supporting plate. A third telescopic rod is installed on the second connecting member. A fourth telescopic rod is installed on the top of the supporting plate. A second scraper is installed on the top of the fourth telescopic rod.

[0006] As a preferred embodiment of this utility model, rollers are installed at the four corners of the bottom of the support base plate, and first telescopic rods are installed at the four corners of the top of the support base plate.

[0007] As a preferred embodiment of this utility model, the first connecting frame is rotatably connected to the second telescopic rod, wherein the second telescopic rod is fixedly connected to the measuring template.

[0008] As a preferred embodiment of this utility model, the second connecting member is rotatably connected to the third telescopic rod.

[0009] As a preferred embodiment of this utility model, a measuring template is installed on the top of both the third and fourth telescopic rods, wherein the measuring template on the second telescopic rod is connected to the measuring template on the top of the fourth telescopic rod via a connecting block.

[0010] As a preferred embodiment of this utility model, the control buttons are electrically connected to the first telescopic rod, the second telescopic rod, the level sensor, the third telescopic rod, and the fourth telescopic rod via wires.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a tunnel invert construction flatness measuring device is provided. Utilizing the device's control button, first telescopic rod, operating panel, and level sensor, the device can perform level sensing and adjustment. Clicking the start button on the control button activates the device, causing the level sensor to detect the levelness of the operating panel. When the ground is uneven, the level sensor detects that one side of the device is higher than the other. If this is detected, the first telescopic rod at the top of the support plate lowers to adjust the operating panel to a horizontal position. Simultaneously, the level sensor detects that the surface is level and stops moving the first telescopic rod. This allows the device to perform level sensing and adjustment, ensuring it remains level at all times, thus making measurements more accurate and avoiding the impact of uneven surfaces on measurement results.

The support plate 15 has a fourth telescopic rod 18 installed on its top. The fourth telescopic rod 18 has a second scraper 19 installed on its top.

[0023] Rollers 2 are installed at the four corners of the bottom of the support base plate 3, and first telescopic rods 4 are installed at the four corners of the top of the support base plate 3, so that the rollers 2 can drive the support base plate 3 to move. The first connecting frame 7 is rotatably connected to the second telescopic rod 8, and the second telescopic rod 8 is fixedly connected to the measuring template 9, so that the second telescopic rod 8 can rotate on the first connecting frame 7. The second connecting piece 16 is rotatably connected to the third telescopic rod 17, so that the third telescopic rod 17 can rotate on the second connecting piece 16. Measuring templates 9 are installed on the top of the third telescopic rod 17 and the fourth telescopic rod 18, and the measuring template 9 on the second telescopic rod 8 is connected to the measuring template 9 on the top of the fourth telescopic rod 18 through the connecting block 11, so that the two sets of measuring templates 9 can be connected.
