Description
Technical field
The present invention relates to construction account field, in particular to room Founder measuring method.
Background technology
At present in the building course in house, quality testing is essential step.For a room, plaster
It is front and rear that the emphasis that upright measurement is the room quality testing is carried out to the ground in room and metope.
But the existing upright measurement to room is substantially by what is be accomplished manually, survey crew needs to use volume
Chi measures the data such as length, width and the Diagonal Dimension on ground or metope comprehensively, is then measured by contrasting these
To data judge whether the room upright, i.e., whether the ground in room or metope are the rectangle of standard and error is
It is no within the limits prescribed.
This metering system usually requires more people while operated, not only wasting manpower and material resources, and operating efficiency is relatively low.
The content of the invention
It is an object of the invention to provide a kind of simple, convenient and efficient room Founder measuring method to improve on
State problem.
What the present invention was realized in：
This upright measuring instrument includes central shaft, and the first measurement bar, angle are disposed with along the central shaft length direction
Dial and the second measurement bar, at least one in first measurement bar and the second measurement bar can be relative to the central shaft
Rotate, be provided with cavity in first measurement bar and second measurement bar, be provided with two cavitys the first motor,
By the described first motor-driven first transmission device, by the first expansion link of first actuator drives, the second motor,
Second motor-driven second transmission device, the second expansion link by second actuator drives and control system
System.
One end of first measurement bar and second measurement bar is provided with matched with first expansion link
One extending port, the other end are provided with the second extending port matched with second expansion link, first expansion link and described
Second expansion link is parallel to each other and is slidably connected to respectively in the cavity, and the control system includes starting or closes the first electricity
The control button of machine and second motor, the control button are arranged at first measurement bar and second measurement bar
On outer wall, scale is provided with first measurement bar, the first expansion link, the second measurement bar and the second expansion link.
Further, first transmission device and second transmission device include pitch wheel and tooth
Bar, the gear are arranged on the output shaft of first motor and the second motor, and it is flexible that the rack is arranged at described first
On bar and the second expansion link.
So, the rotary motion can of the first motor and the second motor is separately converted to by the cooperation of gear and rack
The linear motion of first expansion link and the second expansion link.
Gear and rack engaged transmission are a kind of type of belt drive most widely used in machine driving, have transmission accurate, imitate
Rate is high, compact-sized, the characteristics of reliable operation and long lifespan.
Further, driven pulley is provided between first expansion link and second expansion link, on the driven pulley
It is provided with the driven tooth matched with the rack.Wherein, driven pulley is rotationally connected with first measurement bar and the second measurement bar
Inwall on.
Driven pulley can play a supporting role to the first expansion link and the second expansion link, so that the first expansion link and second are stretched
Contracting bar can be slided stably.
Further, the driven pulley has three, equal along first expansion link or the second length of telescopic bar direction
Even interval setting.
The purpose so set is to be further ensured that the first expansion link and the second expansion link can stably stretch out first
Measurement bar and the second measurement bar.
Further, first transmission device and second transmission device include leading screw and the cunning being connected with each other
Block, the leading screw are connected to by shaft coupling on the output shaft of first motor and the second motor, and the sliding block is connected to institute
State on the first expansion link and second expansion link.
Leading screw and sliding block are conventional standard drive part, effectively can be transported the rotation of the first motor and the second motor
The dynamic linear motion for being separately converted to the first expansion link and the second expansion link, and high transmission accuracy, noise are small.Due to being standard
Part, can directly commercially, therefore convenient and cost is low during replacing.
Further, first motor and second motor are servomotor, and the servomotor, which is connected with, to be watched
Controller is taken, the control system includes PLC, and the servo controller is connected with the PLC.

Embodiment
The quality inspection in house is the important step in house building course, and the ground and metope to room carry out upright measurement
It is then one of main measuring content of house quality inspection.But in the market substantially be not exclusively used in detect room floors or
The instrument of metope squareness, testing staff are substantially by tape measure to the length of room floors or metope, width and right
Diagonal dimension carries out hand dipping to judge the squareness in room.This metering system is more original, it is necessary to multiple-position measurement personnel
Operate simultaneously, not only waste of manpower resource, and measurement efficiency is relatively low.
For the above situation, the technical program provides a kind of upright measuring instrument, and this upright measuring instrument is mainly using rectangular
The equal principle of shape diagonal, intuitively can efficiently measure the squareness of room floors or metope, i.e., the ground in room or
Person's metope shape and the rectangular difference size of standard, difference is smaller to represent that this room is more upright.
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.The present invention implementation being generally described and illustrated herein in the accompanying drawings
The component of example can be configured to arrange and design with a variety of.Therefore, the reality of the invention to providing in the accompanying drawings below
The detailed description for applying example is not intended to limit the scope of claimed invention, but is merely representative of the selected implementation of the present invention
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of protection of the invention.
