[0018] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", "clockwise", "counterclockwise", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply 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 application. The parts involved in the following embodiments, unless otherwise specified, are all conventional commercially available products.

[0019] The embodiment of the present application provides a tunnel face measurement and layout device, which expands the working range of the surveyor through a telescopic rod, and marks the tunnel face measurement points through a paint spray can placed in a paint storage sleeve arranged on the top of the telescopic rod, so as to solve the problems of low measurement efficiency and high risk of layout operation in the prior art where personnel climb up to measure and layout the tunnel face.

[0020] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] This example discloses a tunnel face measurement and layout device, see Figure 1The paint can 1 is placed in a paint storage sleeve 2. The paint can 1 adopts the self-spraying paint commonly used on the market. The paint can 1 is directly inserted into the paint storage sleeve 2 for use, which is convenient for replacement and reduces the time for replacing the paint can 1. A filling layer 6 for fastening the paint can 1 is arranged on the inner wall of the paint storage sleeve 2. The filling layer 6 adopts an elastic material. The filling layer 6 is used to fill the gap between the paint can 1 and the paint storage sleeve 2 to prevent the paint can 1 from moving around in the paint storage sleeve 2 and affecting the marking accuracy. At the same time, the filling layer 6 also applies a force toward the center line of the paint can 1 to the outer wall of the paint can 1, so that the paint can 1 will not fall out of the paint storage sleeve 2 without external force. The paint outlet of the paint can 1 is provided with a vertical nozzle 3 for vertical paint outlet. Compared with the parallel nozzle of the spray can 1, after the paint outlet of the vertical nozzle 3 is aligned with the marked point, the paint can 1 and the palm are The angle formed between the surfaces is larger, which makes it more convenient for surveyors to operate the device for marking. After the parallel nozzles are aligned with the marking point, the angle between the paint spray can 1 and the palm face will be too small. If the angle between the paint spray can 1 on the market and the palm face is too small, the palm face will not be able to serve as a supporting surface, making it difficult for the paint spray can 1 with parallel nozzles to mark the marking points easily, which is inconvenient for surveyors to mark. The bottom of the paint storage sleeve 2 is closed, and the closed bottom supports the paint spray can 1 to prevent the paint spray can 1 from sliding downward when the paint spray can 1 is pressed to spray paint. A telescopic rod 4 is provided at the bottom end of the paint storage sleeve 2. The telescopic rod 4 is a grip similar to a mop in the prior art. A locking device on the grip is also provided on the telescopic rod 4. After the telescopic rod 4 is extended, the locking device is locked to prevent the telescopic rod 4 from changing its length under the action of external force when pressed, thereby affecting the marking.

[0022] See also Figure 2 and Figure 3 The bottom end of the vertical nozzle 3 is provided with a mounting hole 31 for mounting with the paint outlet of the paint spray can 1 , and the top end of the vertical nozzle is provided with a nozzle 32 for discharging paint, and the nozzle 32 is communicated with the mounting hole 31 .

[0023] Also, see Figure 1 A handle 5 for easy gripping is provided at one end of the telescopic rod 4 away from the paint storage sleeve 2, and the measurement personnel can use the handle 5 to better align the paint spray can 1 with the marked point.

[0024] In this embodiment, the height of the paint storage sleeve 2 is smaller than the height of the paint spray can 1, and the part of the paint spray can 1 outside the paint storage sleeve 2 is convenient for the measurement personnel to grasp and replace the used paint spray can 1, and the paint spray sleeve will not affect the marking of the paint spray can 1.

[0025] When using the device, first replace the spray head of the paint spray can 1 with the vertical nozzle 3, then install the paint spray can 1 into the paint spray sleeve, then extend the telescopic rod 4 and lock the telescopic rod 4, finally align the vertical nozzle 3 with the marking point, then hold the handle 5, press the vertical nozzle 3 against the palm surface, and finally hold the handle 5 and apply force in the direction of the palm surface to complete the marking.

[0026] Although some preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the inventive concept. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
