Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage device for surveying equipment in a mine with high humidity.

[0002]

[Prior art]

 Conventionally, in tunnel construction, etc., especially in the shield propulsion method, there are frequently surveying operations performed during excavation work. This surveying work is carried out while bringing various surveying instruments into the mine and moving to the surveying place.

[0003]

[Problems to be solved by the device]

 Conventionally, in a mine where the excavation environment is not good, such as the shield propulsion method, the humidity and temperature are high.Therefore, various surveying instruments used for surveying may have water droplets attached during use or storage, and The lens of the device becomes cloudy. As a result, when surveying, the surveying equipment had to be maintained and used, resulting in poor work efficiency. Furthermore, there was a problem that the performance and functions of precision instruments used for surveying deteriorate.

Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to store various surveying instruments in a dry state in underground work with high humidity or shield propulsion work. However, it is to provide a storage device for surveying equipment that can be used in good condition at any time according to the progress of the work and facilitate the survey work.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a dryer that generates warm air and a drying chamber that stores and dries the surveying instrument are connected by a blower pipe. Furthermore, the storage device was mounted on a mobile trolley so that it could be moved to the place of use at any time.

[0006]

[Action]

 According to the present invention, various surveying instruments used in underground construction with high humidity and shield propulsion method are stored in the drying room, and the surveying instruments are stored in good condition by operating the dryer, and immediately when necessary. Since it can be used for various purposes, surveying work can be performed smoothly. In addition, by installing a drying room or dryer equipped with various surveying equipment on a mobile trolley, it can be moved to any place of use and used at any time.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of a storage device for a surveying instrument according to the present invention. A dryer A and a drying chamber B are installed on the moving carriage D. The dryer A and the drying chamber B are connected by a blower pipe C. The dryer A is composed of a blower (not shown) using an electric heater as a heat source. The dryer A sends the warm air warmed by the heater to the drying chamber B 2 via the blower pipe C by the blower. A timer 10 is attached to the dryer A to prevent overheating of the drying chamber B. Furthermore, a power plug 20 is attached to the side surface of the dryer A.

The drying chamber B is formed by a steel box body 1 and is provided with a door 2 so that one side surface can be opened and closed. The door 2 is provided with a stopper 3 to prevent the door 2 from being opened accidentally after the door 2 is closed. This can effectively prevent external moisture and the like from entering the inside of the drying chamber B. Further, a hygrometer 4 for displaying the humidity inside the box 1 and a thermometer 5 for displaying the internal temperature are attached to the door 2.

The inside of the steel box 1 is provided with a heat insulating material so as not to release the heat by the warm air sent from the dryer A. Further, inside the box body 1, a required number of shelves (not shown) for organizing and storing surveying instruments are provided. A ventilation port 6 for ventilating the drying chamber B is provided on the side surface of the box 1.

Next, a method of operating the storage device according to the present invention will be described. First, the surveying instrument is stored and stored in the drying chamber B. After that, the hygrometer 4 in the drying chamber B is viewed and the dryer A is operated as necessary. At this time, the power plug 20 of the dryer A is inserted into an outlet (not shown). Then, the timer 10 is set to an appropriate time so that the drying chamber B does not overheat.

By this operation, the warm air warmed by the dryer A is sent into the drying chamber B through the blower pipe C. As a result, the humidity of the drying room B is lowered, and the stored surveying instrument can be protected from moisture and the like. Then, the thermometer 5 monitors the drying chamber B so as not to overheat. Further, the ventilation port 6 is used to ventilate the drying chamber B as needed.

Since the storage device according to the present invention has a considerable weight, as shown in FIG. 2B, a rear cart 40 of the shield machine 30 is provided with a surveying instrument storage space, in which a dryer A and a drying chamber are installed. It is preferable to install B and. Here, FIG. 2A is a side view of the leading portion of the storage device according to the present invention connected to the shield machine 30. The drier A and the drier B move on the track while being mounted on the rear carriage 40 of the shield machine 30.

As described above, in the shield propulsion method, the dryer A and the drying chamber B are mounted on the rear carriage 40 and are connected to the shield machine 30 to move. As a result, since the drying room B in which the surveying equipment is stored is always close to the place of use, the surveying operation becomes easier. In some cases, the dryer A and the drying chamber B do not move in a state of being connected to the shield machine 30, but the moving carriage D equipped with the dryer A and the drying chamber B does not move on its own. You may make it run.

[Effect of device]

 According to the present invention, it is possible to store various kinds of surveying equipment used in underground construction with high humidity and shield propulsion construction in a dry state. This enables the surveying equipment to be used in good condition at any time, responding to the progress of work. As a result, the surveying work can be performed smoothly, and the performance of the precision instrument for surveying can be maintained.
