Description
Technical field
The utility model belongs to engineering measuring technology field, is specifically related to a kind of night work levelling pole that can be used for night-environment measurement of the level.
Background technology
Electronic level has that measuring speed is fast, reading is objective, labour intensity is little, homework precision is high, measurement data is convenient to input computing machine and easily realizes measurement of the level inside and outside trade integration feature and be widely used.But electronic level exists when reading and requires high shortcoming to the illuminance of levelling pole, cannot reading, light lower in illuminance is uneven.
In real work, part surveying work necessarily requires to carry out under night-environment: as the settlement observation of Urban Underground rail track, the high-acruracy survey of overhead railway, and due to daytime vehicle produce vibrations measuring accuracy is reduced, thus require vehicle at night rareness environment under carry out the experiment such as bridge moving static test and settlement of highway observation.Because illumination condition at night does not often reach requirement, spirit-leveling instrument None-identified is caused to go out bar code on levelling pole; In actual measurement process, levelling pole must move simultaneously, and when distance spirit-leveling instrument is far away, adopts the lighting system of powerful lighting or electric torch to be all not suitable for observation.
Utility model content
In order to overcome the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of night work levelling pole, this night work levelling pole can complete measurement operation in night-environment, and structural design is simple, reasonable, can support the use with various optical level.
The utility model is achieved through the following technical solutions:
A kind of night work levelling pole, comprises the hollow cubic body blade surrounded by header board, backboard and two, left and right side plate, all offers chute, be provided with tempering ground glass in chute in the middle part of the header board of hollow cubic body blade He in the middle part of backboard; The tempering ground glass of header board is provided with bar code, backboard is provided with circular bubble, be provided with light fixture in hollow cubic body blade inside.
Described light fixture is made up of some row's LED framves and the LED be arranged on LED frame.
Described some row's LED framves are equidistant to be fixed on two side plate inwalls of hollow cubic body blade.
A side plate outer wall of hollow cubic body blade is provided with the gauge tap of LED.
The described tempering ground glass be arranged in the middle part of header board in chute is the tempering ground glass of transmittance 60%, and the tempering ground glass be arranged in the middle part of backboard in chute is the tempering ground glass of transmittance 80%.
The frosting of described tempering ground glass is inner towards hollow cubic body blade.
Two side plate outer walls of hollow cubic body blade are respectively equipped with symmetrical handle.
Described header board, backboard and two, left and right side plate are made up of aluminium sheet.
Compared with prior art, the utility model has following useful technique effect:
Night work levelling pole of the present utility model adopts hollow cubic body blade, header board, backboard offer chute, and at chute internal fixtion tempering ground glass, adopt tempering ground glass, reading can not be affected because of illumination when this levelling pole is worked by day, can uniform light be made when working at night simultaneously, avoid the reading problems produced because uneven illumination is even.This levelling pole is also etched with bar code on the tempering ground glass of header board, the LED of illumination is arranged on hollow cubic body blade inside, when night work, black bar code is clearly presented on spirit-leveling instrument alidade through tempering ground glass by the light of LED, vertical chi person also can by the light through glass, be clear that the leveling bubble in circular bubble, convenient in night work.Night work levelling pole of the present utility model presents symmetrical structure, simplicity of design, rationally, can complete measurement operation, and can support the use with various optical level in night-environment.
Further, in order to prevent ambient humidity on the impact of frosted tempered glass frosting, the frosting of frosted tempered glass is placed towards hollow cubic body blade inside.
