During measurement, the plane needs to be adjusted to a horizontal posture, and whether the assembly quality of each part meets the technical requirements and the deformation condition of each part in the using process is checked through measuring points of the relative positions of each large part of the plane.
Aircraft leveling requirements:
1. the airplane needs to meet the installation full state during horizontal measurement, the onboard equipment is complete, no fuel oil exists in a fuel tank, and no personnel or other redundant loads exist on the airplane.
2. All flaps of the aircraft surface should be closed and all control surfaces should be in a neutral position.
3. The measurement-independent work must not be carried out during the aircraft measurement.
The requirements of relevant measurement environments are met during the horizontal measurement of the airplane, and the requirements mainly comprise the following items:
1. the airplane leveling measurement should be carried out indoors as much as possible to avoid the interference of the external environment.
2. The device does not have indoor measurement conditions, and can only avoid the influence of strong wind when measuring outdoors.
The current situation of leveling aircraft is as follows:
1. the lighting of external light source needs the hand of dispatch special messenger of current dipperstick, extravagant manpower and material resources, and the dipperstick rusts easily in the use, and scale oxidative wear leads to the reading error big.
2. The present dipperstick needs to send the special person to hold up fixedly to keep the dipperstick vertical state, artificial holding up the chi and having the deviation, still influence the exactness of final reading very easily when extravagant manpower.
3. When outdoor wind power of an existing measuring scale is large, the measuring scale is easily disturbed by wind power, and therefore interpretation of data is affected.
Disclosure of Invention
The purpose of the invention is: a rechargeable light-emitting measuring scale for measuring the level of an airplane is provided. The invention has the characteristics of simple structure, simple and convenient use, manpower saving, strong applicability, accurate reading and high efficiency.
The technical scheme of the invention is as follows: the utility model provides a measure horizontal chargeable formula of aircraft and send out light dipperstick, includes handheld portion, handheld portion bottom and printing opacity chi top are articulated, and the chi face of printing opacity chi is equipped with the scale mark, and the scale mark back is provided with the luminous integrated board of LED.
In the rechargeable light-emitting measuring scale for measuring the level of the airplane, the LED light-emitting integrated board is further connected with a battery pack for supplying power to the LED lamp on the LED light-emitting integrated board, and a switch for controlling the LED lamp to emit light/extinguish.
In the rechargeable light-emitting measuring scale for measuring the level of the airplane, the LED light-emitting integrated board is further connected with a charging interface for charging the battery pack, and the charging interface is used in cooperation with a charger.
In the rechargeable light-emitting measuring tape for measuring the level of the airplane, the switch is mounted near the handheld portion.
In the rechargeable luminous measuring scale for measuring the level of the airplane, the top end of the handheld part is of a pointed cone structure.
In the rechargeable luminous measuring tape for measuring the level of the airplane, the handheld part is made of an aluminum alloy material.
In the rechargeable luminous measuring scale for measuring the level of the airplane, the light-transmitting scale is made of PC plastic.
In the above rechargeable light-emitting measuring tape for measuring aircraft level, the battery pack is a lithium polymer battery.
The invention has the advantages that: the invention has the advantages of convenient use, labor saving and labor efficiency improvement. Operating personnel does not receive the influence of ambient light when measuring the level for the aircraft, at the darker use place of light, need not arrange the special person again and provide the light source for the measurement, open the switch by the personnel of handheld luminous dipperstick after the power makes it luminous for LED provides the power, and the observer just can conveniently observe the measured value directly perceivedly through the theodolite.
The PC plastic with strong light transmission and good resistance to weak acid, weak base and alcohols at normal temperature is selected to manufacture the light transmission ruler, and other parts are made of aluminum alloy materials; this setting can avoid rustting and scale oxidation wear to lead to the big defect of reading error.
The bottom of the handheld part is hinged with the top end of the light-transmitting ruler, so that the light-transmitting ruler can naturally droop through gravity in the using process, the operation that a measuring ruler needs to be held by a special person for fixing by hands to keep the measuring ruler in a vertical state is replaced, the deviation caused by manual holding of the ruler is avoided, the manpower is saved, and the precision of final reading is improved; the invention has larger integral mass, can avoid being interfered by external natural wind and enlarges the application range.
The battery pack adopts the light-weight lithium polymer battery, has higher electric power storage capacity and higher safety compared with the traditional button-type battery and other types of batteries, has stronger advantages in the aspects of environmental protection and sustainable use, has simple integral structure and convenient use, and controls the LED light-emitting integrated board to emit light through the switch, thereby achieving the purposes of convenient use and high efficiency.
In conclusion, the invention has the characteristics of simple structure, convenient use, labor saving, strong applicability, accurate reading and high efficiency.
