Tunnel steelframe gradient detection device

Technical Field

The application belongs to the technical field of tunnel check out test set, more specifically says, relates to a tunnel steelframe gradient detection device.

Background

At present, when the inclination of the tunnel steel frame is detected, a detector is generally adopted to detect the inclination of the tunnel steel frame by putting down a plumb bob on the top of the tunnel steel frame through a detection frame (a plumb bob method) as shown in figure 1. The plumb bob method is influenced by factors such as weather, arrangement of detection frames, personnel operation and the like, the measurement precision cannot be guaranteed, the working efficiency of the plumb bob method is low, the time for detection personnel to stay in the tunnel is long, toxic and harmful gas can damage the health of a human body, the dangerous stay time in the tunnel is long, and the probability of personnel damage is high.

The invention provides the method for detecting the inclination of the tunnel steel frame, which aims to make the detection result more accurate and make up the blank of the equipment for detecting the inclination of the tunnel steel frame. Through the literature search, the same public reports as the invention are not found.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "connected" or "disposed" to another element, it can be directly on the other element or be indirectly connected to the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. The meaning of "a number" is one or more unless specifically limited otherwise.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings that is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present application.

Referring to fig. 2 and fig. 3 together, a description will now be given of the inclination detecting apparatus for a tunnel steel frame according to an embodiment of the present application. The tunnel steel frame inclination detection device comprises an upper telescopic micrometer 1, a quadrangular support 2, a horizontal bubble device 3, a lower telescopic micrometer 4 and a monopod 5; the assembly relationship is as follows: the upper surface of the quadrangular support 2 is provided with an upper telescopic micrometer 1, the middle part of the side surface is provided with a horizontal bubbler 3, the lower surface is provided with a lower telescopic micrometer 4, and the quadrangular support is arranged on a monopod 5.
