Description
Technical field
The utility model belongs to Surveying Engineering support meanss technical field, and in particular to one kind is easy to the mapping of leveling formula to use
Support.
Background technology
Mapping is based on computer technology, photoelectric technology, network communications technology, space science, information science, with complete
Ball aeronautical satellite alignment system (GNSS), remote sensing (RS), GIS-Geographic Information System (GIS) are technological core, by the existing spy in ground
Sign point and boundary line by measurement means obtain reflection ground present situation a figure and positional information, for engineering construction planning and designing and
Administration is used.
It is surveying instrument to survey and draw the instrument used, and for the ease of operation, support frame can be also used, to prop up surveying instrument
Support.Because mapping is the shape of natural geography factors or earth's surface Artificial facilities, size, locus etc. to be measured and adopted
Collection, therefore, mapping are typically operation in the wild.In the wild during operation, because the physical features environment in the external world differs, ground would generally be in
Now different degrees of roughness, it when support frame is installed on the ground, can present crooked, have a strong impact on mapping precision.
Therefore, people can set adjustable support frame, and in setting level meter on support frame, will be surveyed as much as possible before mapping
Paint instrument leveling.
In the prior art, adjustable support frame for mapping is typically tripod, and three legs of tripod are to stretch
Contracting bar, the expansion link are to coordinate control by the equally distributed spacing hole in longitudinal direction and locating part, i.e. locating part often moves one
Under, expansion link just ramps up or reduced downwards the isometric height of spacing distance between two spacing holes.Set on tripod
Level meter is put, or in setting sash weight on tripod, the state of level meter or sash weight is judged on surveying instrument support frame according to the observation
Whether end face is horizontal, if being judged as crooked, ramps up or reduces by one therein or two legs downwards, change three
The relative altitude of leg, to by the upper surface leveling of whole support frame.However, during existing bracket adjustment, leg is often adjusted
Height once is all changeless, even if this changeless height is designed to very thin, it is also difficult to be supported frame
Small regulation, for more fine mapping, the small regulation can also influence huge.
Utility model content
The utility model is intended to offer one kind and is easy to leveling formula mapping support, and the support can realize minor adjustments, with
Ensure the mapping precision of surveying instrument.
It is easy to leveling formula mapping support, including supporting plate and at least three branch positioned at supporting plate lower end in this programme
Pin, supporting plate are provided with level meter, and the supporting plate lower end offers multiple blind holes that Open Side Down, the quantity and leg of blind hole
Quantity it is consistent, and the corresponding leg of each blind hole；The bottom of blind hole is provided with electromagnet, and electromagnet is electrically connected with power supply；It is blind
Rubber ring is provided with hole, the upper end of leg corresponding to blind hole passes through rubber ring, and positioned at the top of the rubber ring and right positioned at its
Answer the lower section of electromagnet, the end face of leg upper end is provided with permanent magnet, permanent magnet with and its corresponding electromagnet magnetic pole it is identical,
Leg side wall offsets with rubber ring.
It is easy to leveling formula mapping support using in this programme, Open Side Down for blind hole, for accommodating leg.Power supply connects
Logical, electromagnet can produce different magnetic field, and change the size of current of power supply, and magnetic field intensity can become caused by electromagnet
Change.Rubber ring is flexible, and leg side wall offsets with rubber ring, and rubber ring can form the effect of spacing fixation to leg；It is another
Aspect, the leg that the elasticity of rubber ring can allow to be located therein carry out micro rotation.Leg is provided with permanent magnet, permanent magnet with
Identical with the magnetic pole of its corresponding electromagnet, after electromagnet is powered, electromagnet and permanent magnet can produce repulsive interaction.
Technical principle of the present utility model is：When needing to be finely adjusted support, power-on, electromagnet and permanent magnet
Between produce mutual repulsive interaction, can be produced under the spacing fixation of rubber ring, between electromagnet and permanent magnet micro-
Small gap, the small gap can allow leg to carry out micro rotation, to realize the fine setting to support.Leg is finely adjusted
Afterwards, the repulsive force between permanent magnet and electromagnet can be supported to leg, and under the cooperation of rubber ring, and the support can be compared with
For stabilization, ensure horizontality of the support smoothly after fine setting, be easy to survey and draw operation.
It is of the present utility model to have technical effect that：Compared to existing technologies, scheme of the present utility model can both be carried out
The coarse adjustment of leg, support is set to be located at the state of relative level；Also the state that can be shown according to level meter, utilizes electromagnet and permanent magnetism
Repulsive interaction between iron, and the cooperation of rubber ring, realize the fine setting to support, make support accurately horizontal in one
State, it ensure that the mapping precision of surveying instrument.
It is the preferred scheme based on such scheme below：
Preferred scheme one：The openend of the blind hole is outward-dipping.So as in the blind hole at least three legs can shape
Into a similar taper, for upright compared to leg, support is more steady.
Preferred scheme two：Based on preferred scheme one, the level meter has at least two.For compared to one level meter,
The horizontality of support is observed by least two level meters, precision is more guaranteed.
Preferred scheme three：Based on preferred scheme two, the level meter has three, three level meter distributions triangular in shape.Three
Point forms a plane, and the horizontality precision that three level meters of distribution triangular in shape are shown is higher.
Preferred scheme four：Based on preferred scheme three, the blind hole is lower small bellmouth upper greatly, and the outline of rubber ring is
Up big and down small taper, the endoporus of rubber ring is straight hole.For leg when being rotated, its portion more on the lower, the amplitude of rotation is bigger,
The outline of rubber ring is arranged to up big and down small taper, and the endoporus of rubber ring is arranged to straight hole, i.e., under rubber ring
Portion's thickness is more than the thickness on top, thus while the endoporus for ensureing leg and whole rubber ring closely offsets, moreover it is possible to allow
The amplitude for the partial turn that leg offsets with rubber ring bottom is bigger.
