Description
Technical field
The utility model is related to a kind of semi-automatic measuring levelling rod, belongs to engineering mapping technical field.
Background technology
The level measuring rule being applied at present in technical levelling is generally matching used two levelling rods, is surveyed in level
Two are needed to help chi personnel one in front and one in back, to hold handle on survey station according to the level(l)ing bubble position on levelling rod, make water in amount
Object staff is maintained at vertical position, then waits spirit level operating personnel to read the altimetric reading on levelling rod.This mode of operation
To helping the patience of chi personnel, helping chi to need the stability kept often to have higher requirement, measurement difficulty is big, operating efficiency
It is low.Levelling rod is easily rocked during due to helping chi, it is not easy to find the vertical position of levelling rod, even if instantaneous find also is difficult to
Keep for a long time, can not more ensure the absolute vertical of levelling rod during reading, therefore larger measurement error can be produced unavoidably.Separately
Outside, because the use environment of levelling rod is outdoor, abrasion or the chi body of scale are easily caused under rain and dew Exposure to Sunlight for a long time
Deformation, influences the service life of levelling rod.
Utility model content
The purpose of this utility model is the drawbacks described above for overcoming existing level measuring rule to exist, it is proposed that semi-automatic measuring
Levelling rod, it realizes reduction and helps chi difficulty, reduces because levelling rod deflection is led by increasing bascule, transparent lightweight shell
Measurement error, the function of extending ruler body service life of cause.
The utility model is realized using following technical scheme：
A kind of semi-automatic measuring levelling rod, including level ruler body, a shell and a bascule；Shell shape is
Reverse frustoconic, is enclosed on the external side of level ruler, upper end open, lower end sealing；Bascule includes a sealed reverse frustoconic shell
Body and a heavy spheroid in portion disposed within；Wherein, the radius of heavy spheroid between reverse frustoconic housing upper bottom radius and under
Between the radius of bottom, reverse frustoconic housing side or bottom surface are fixedly connected with shell upper end, and its bottom surface and level ruler body upper end
It is fixedly connected, level ruler body lower end is fixedly connected with outer casing bottom.The overall similar roly-poly shape of chi body, under deflected condition more
Easy automatic returning center of gravity, when bascule reaches the state of balance, drives level ruler body to be maintained at its center of gravity line and chi body
On the position of coincidence, levelling rod is set to be easier to be stably held in vertical state.
Preferably, foregoing heavy spheroid and reverse frustoconic inner walls smooth contact, reduce spheroid and reverse frustoconic housing
Frictional force between inwall, spheroid slip is smooth, and reduces possible abrasion.
Preferably, foregoing heavy spheroid is iron ball, steel ball, Shi Qiuzhong one kind, and density of material is big, and materials are easy, and cost is low.
Preferably, the material of previous housings and reverse frustoconic housing is makrolon, polymethyl methacrylate or polychlorostyrene
One kind in ethene lightweight transparent material, texture material is hard and light, and cost is low, is carried during convenient open air measurement.
Preferably, handle is provided with the outside of previous housings, chi body vertical position is kept when being easy to help chi personnel control and reading
Stability.
Preferably, provided with circular level(l)ing bubble on the outside of previous housings, it can intuitively show whether chi body is in vertical position
Put.
The utility model make use of spheroid to be moved in the truncated cone-shaped container of handstand, eventually stops at the centre of sphere and passes through the circle
This principle on the position of platform shape center line, is fixed on level ruler body one end using this device as bascule, chi body is existed
Close to bascule during vertical state level ruler body " automatic " can be driven to revert to center of gravity line based on above-mentioned principle to put down with ground
It can stablize on the position of weighing apparatus and relatively and maintain this vertical state.Shell protects it as far as possible not in levelling rod body is sealed in
Scale-wearing is caused by the galling of external force.
The beneficial effects of the utility model are：On the one hand, the operation difficulty of chi personnel is helped when reducing measurement, makes levelling rod
It is more easy to be maintained at vertical state, improves operating efficiency during measurement, is missed while reducing and being measured caused by oblique leveling staff
Difference.On the other hand, the abrasion to levelling rod elevation scale is effectively prevent in long-time outdoor operations.
Brief description of the drawings
Fig. 1 is the use state figure of the utility model embodiment.
In figure：1st, shell；2nd, handle；3rd, foot pin；4th, reverse frustoconic housing；5th, heavy spheroid；6th, level ruler body；7th, circle
Shape level(l)ing bubble.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of semi-automatic measuring levelling rod as shown in Figure 1, including level ruler body 6, shell 1 and a reverse frustoconic are put down
Weigh device.The material of shell 1 is transparent pvc material, and shape is rounding mesa-shaped, is enclosed on the outside of level ruler body 6, upper end
It is connected to reverse frustoconic bascule side, upper end open, lower end sealing.Bascule includes a reverse frustoconic housing 4 and put
The heavy spheroid 5 in portion in the inner, the radius of heavy spheroid 5 between reverse frustoconic housing 4 upper bottom radius and bottom radius it
Between, the side of reverse frustoconic housing 4 is fixedly connected with the upper end of shell 1, and the lower end of reverse frustoconic housing 4 is consolidated with the upper end of level ruler body 6
Fixed connection, the lower end of level ruler body 6 is fixedly connected with the bottom of shell 1, center of gravity line and the level ruler body 6 of reverse frustoconic housing 4
Center of gravity line keep overlap.Wherein, the material of reverse frustoconic housing 4 is makrolon, and heavy spheroid is steel ball, and sphere is through polishing
Contact, can freely roll wherein with the inner wall smooth of reverse frustoconic housing 4.The outside of shell 1 is provided with handle 2 and circular level(l)ing bubble
7。
Use process of the present utility model is as described below：In engineering survey on the spot, levelling rod is stood on chi by survey crew
On pad 3, when levelling rod is helped to close to vertical state, the steel ball in bascule can be slided to down automatically under gravity
Truncated cone-shaped lower housing portion, and drive reverse frustoconic housing 4 further to swing to the position on square impact ground, make the center of gravity line of bascule
Plumbness is kept with ground, the center of gravity line for the level ruler body 6 being now connected on bascule is also just perpendicular to the ground,
I.e. levelling rod is in vertical state.Now help chi personnel only need to gently help the handle 2 of level ulnar surface, confirm the circle on levelling rod
Level(l)ing bubble 7 is maintained at middle position, you can read the corresponding elevation number of degrees on levelling rod, more easily just obtains error smaller
Elevation numerical value.
Certainly, the above is only preferred embodiment of the present utility model, it is impossible to be considered as being used to limit to this practicality newly
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With equivalent change and improvement made in new essential scope etc., patent covering scope of the present utility model all should be belonged to
It is interior.
