Abstract
A rapid dotting tool for tunnel face excavation comprises a main body, wherein the front end of the main body is hinged with a movable main body; the movable main body is positioned above the hinge position and is connected with the main body through a spring, the pull wire is connected below the hinge position, and the pull wire penetrates through a pull rod hinged with the rear end of the main body through a hole at the head end and the tail end of the main body; one side of the pull rod is provided with a movable handle; the movable handle is fixed in the straight clamping groove at the tail end of the main body. The operation needs construction survey crew to hold the tool of dotting to aim at the point position that needs the lofting dotting with the spray paint nozzle, and the handle is through wire rope and "7" style of calligraphy claw with the force effect from the spray paint nozzle of gripping back and lofting dotting.
Description
Technical Field
The utility model relates to the technical field of tunnel excavation contour line construction measurement lofting, in particular to a rapid dotting tool for tunnel face excavation.
Background
The blasting contour effect of the tunnel face in the complex geology is often not ideal at present, and particularly when a full-section excavation construction method is adopted, the upper and lower footage mileage is different; under the condition that three-arm drill jumbo can not be used in small-section tunnel construction, when constructing with simple excavation rack, the excavation face often can't be hugged closely to simple excavation rack, and manual work is used hand mark of spraying paint to get into the face of working when the excavation contour line lofting, and traditional extension bar installation writing brush is stained with red paint and is got into the operation very inconvenient, and the foresight needs two at least people to cooperate and inefficiency when lofting, and the extension is used in tunnel excavation contour line lofting construction process. Therefore, how to solve the problems and form a simple, quick and long-distance dotting tool is a novel problem to be solved by the use.
Disclosure of Invention
The utility model provides a rapid dotting tool for tunnel face excavation, which is convenient for operation of measuring staff and ensures safety of the measuring staff, and aims to solve the problem that a construction measuring staff is difficult to contact a face by manually and automatically shaking a paint spraying mark dotting when a tunnel excavation contour line is lofted.
The utility model is realized by adopting the following technical scheme:
the utility model provides a tunnel face excavation quick dotting tool, includes main part (4), its characterized in that: the front end of the main body (4) is hinged with the movable main body (1); the movable main body (1) is positioned above the hinge position and is connected with the main body (4) through a spring, the stay wire (2) is connected below the hinge position, and the stay wire (2) penetrates through a pull rod (3) hinged with the rear end of the main body (1) through a hole at the head end and the tail end of the main body (4); one side of the pull rod (3) is a movable handle; the movable handle is fixed in a straight clamping groove at the tail end of the main body (4).
The movable main body (1) is made of a common 3mm steel plate, the hinged joint of the movable main body (1) and the movable claw in the shape of a 7 is hinged, and a fixed ring is arranged.
The diameter 2mm hole is made to main part (4) head end, and the wide 1cm draw-in groove of tail end open "straight" style of calligraphy, diameter 2mm hole is made to perpendicular draw-in groove face, and head and tail end trompil face is the parallel face.
The stay wire (2) is a steel wire rope.
The utility model has the beneficial effects that;
the rapid dotting tool disclosed by the utility model is light, convenient and rapid, has high manufacturing simplicity and high cost performance, perfects a hand-operated paint spraying system, solves the problem that the excavation bench cannot be manually placed for dotting when being far away from a palm face, reduces the time for measuring and placing a sample, ensures the safety of measuring personnel for placing a sample, and has extremely wide popularization value.
The utility model is applied to quick dotting of the paint spraying mark when the tunnel excavation contour line is lofted, and has high measuring operation efficiency; staff can loft and dott in the primary support, and the risk that the tunnel face falls the piece and hurts people under the bad geological conditions is effectively avoided.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a side view of the quick pointer of the present utility model;
description of the embodiments
The specific embodiments of the present utility model will be further described with reference to the accompanying drawings:
the first step: the automatic hand-operated paint spraying cylinder is arranged in the front end circular ring of the dotting device, and the nozzle is forwards.
And a second step of: the handle is used for dotting the paint spray nozzle aiming at the lofting position after the dotter is held by one hand or two hands, the pull rod is pulled, and the paint spray cylinder button is pushed downwards in the upper direction of the movable main body, so that paint spraying is realized.
