The measuring device comprises a first ruler and a second ruler which are perpendicular to each other. The heading direction of laser beams emitted by the laser beam emitting device is perpendicular to the surfaces, marked with scales, of the first ruler and the second ruler. The shafting base measuring instrument of the utility model has the advantages that the measurement time can be reduced, the measurement form is simple, and the measurement precision is high.
Description
(1) technical field
The utility model relates to a kind of shafting foundation surveying instrument.
(2) background technology
Axle is theoretical centerline determined center line of shafting while being Ship Design.When axle system and main frame are installed, axle is that theoretical centerline is important reference for installation, according to axle, is that theoretical Shen heart line determines that the installation site of main frame and axle are each transmission shaft and installing positions of bearings.
Therefore, in shipbuilding process, high to the positioning accuracy request of the pedestal of placement axle system and main frame etc.To the location of pedestal, be to measure by steel ruler, this mode not only measuring process is long in the past, and measurement form is very complicated, measuring accuracy is difficult to guarantee.
(3) summary of the invention
The purpose of this utility model is to provide a kind of shafting foundation surveying instrument, not only can reduce and measure the activity duration, and measurement form is simple, measuring accuracy is high.
For achieving the above object, the utility model is by the following technical solutions:
A kind of shafting foundation surveying instrument, it is characterized in that: comprise laser beam emitter and measurement mechanism, described measurement mechanism comprises vertically disposed the first scale and the second scale mutually, and the working direction that described laser beam emitter gives off laser beam identifies graduated surface perpendicular to described the first scale and the second scale.
The utility model can improve by following scheme:
Described a kind of shafting foundation surveying instrument, is characterized in that: described the first scale and the second scale form " ten " font.
Described a kind of shafting foundation surveying instrument, it is characterized in that: described the first scale is that vertical state its identify graduated surface and also have a scale center line that is vertical state, described the second scale is horizontality and has one and have vertical bottom surface, scale surface with its sign, and the intersection point of described scale center line and described bottom surface forms the initial point of described scale.
Described a kind of shafting foundation surveying instrument, is characterized in that: described the first scale and the second scale are made by aluminum alloy materials, and its section configuration is " returning " font.
Described a kind of shafting foundation surveying instrument, is characterized in that: also comprise a pair ofly connecting respectively described the first scale and the second scale prevents the diagonal brace of its distortion to allow.
Described a kind of shafting foundation surveying instrument, is characterized in that: described laser beam emitter is cross line laser or a word laser line generator.
The utility model not only can reduce measures the activity duration, and measurement form is simple, measuring accuracy is high.

(5) embodiment
A shafting foundation surveying instrument, comprises laser beam emitter (there is no accompanying drawing) and measurement mechanism 1.As shown in Figure 1, described measurement mechanism 1 comprises vertically disposed the first scale 11 and the second scale 12 mutually, and both form " ten " font.Described the first scale 11 also has a scale center line 11-1 who is vertical state for vertical state its identify graduated surface, described the second scale 12 is for horizontality and have one and have with its sign the bottom surface 12-1 that scale is surperficial vertical, and the intersection point of described scale center line 11-1 and described bottom surface 12-1 forms the initial point 13 of described scale.
Measurement mechanism 1 also comprises and a pair ofly connects respectively described the first scale 11 and the second scale 12 prevents the diagonal brace 14 of its distortion to allow.In order to alleviate the weight of measurement mechanism 1 and easy to carry, described the first scale 11 and the second scale 12 are made by aluminum alloy materials, and its section configuration is " returning " font, as shown in Figure 2.
During manufacture, in order to guarantee that the first scale 11 and the second scale 12 respectively identify graduated surface at grade, described the first scale 11 is divided into two-section and is welded in respectively on the end face and bottom surface of the second scale 12, described end face and bottom surface for sign have two perpendicular surfaces of scale surface,
Described laser beam emitter is cross line laser or a word laser line generator.The working direction that described laser beam emitter gives off laser beam is perpendicular to described the first scale 11 and the graduated surfaces of the second scale 12 sign, and it is " ten " word or " one " font that laser beam respectively identifies at the first scale 11 and the second scale 12 image 3 that graduated surface becomes.
During use, as shown in Figure 3 or Figure 4, when the pedestal 2 of placement axle system and main frame etc. is theoretical centerline below or above axle, center line and the axle of the laser beam that it is sent in the position of adjustment laser beam emitter are that theoretical centerline coincides, measurement mechanism 1 is placed on the surface 21 of the pedestal 2 of placing axle system and main frame etc., the image 3 becoming on the first graduated surfaces of scale 11 sign by laser beam is just readable goes out concrete numerical value, this numerical value is the level height of the pedestal 2 of placing axle system and main frame etc., measurement mechanism 1 is adjusted in level left and right drops on described scale center line 11-1 the center line of its laser beam of sending of laser beam emitter, now, the pedestal of placing axle system and main frame etc. also directly scene draw.Thus, the location (H, W) of the pedestal of placement axle system and main frame etc. has just obtained.
Above-described embodiment is better embodiment of the present utility model; but embodiment of the present utility model is not limited to this; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; be equivalent substitute mode, within being included in protection domain of the present utility model.
