Description
Technical field
The present invention relates to a kind of portable level ruler support, particularly relate to the matching used portable rack of a kind of and accurate invar bar code levelling pole.
Background technology
In highway or railway construction, the slip-stick artist often need to carry out every engineering survey to highway or the residing landform of railway, and precise leveling is exactly one of wherein important measure the item.We know, these measurements all must be carried out out of doors, yet outdoor environment is generally relatively poor, particularly run into the weather of blowing, quality and the physical dimension of adding accurate invar bar code levelling pole itself are larger, hand only according to the people just is difficult to the levelling pole righting is held up directly, directly causes producing larger measuring error.In addition, whole measuring process all is to help levelling pole by staff, and labour intensity is large, also can tremble with the human body natural, increases observer's observation difficulty, and then prolongs Measuring Time.Generally speaking, the measuring method that adopts this manpower to help, measuring accuracy and measuring speed all can not be guaranteed.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, the portable level ruler support that a kind of simple in structure, convenient operation is provided and improves measuring accuracy and measuring speed.
The technical solution adopted in the present invention is: the fixed mount and the telescope support that is fixedly connected with described fixed mount that will the present invention includes frame type structure, the described fixed mount left and right sides is equipped with fastener, and levelling pole is arranged in the inside casing of described fixed mount by described fastener.
Preferably, described fixed mount rear end is provided with V-structure, and described telescope support is fixedly connected with described V-structure.
Preferably, described fastener is made as holding screw, and the end of described holding screw is arranged in the inside casing of described fixed mount.
Preferably, the end of described holding screw is provided with the rubber blanket I.
Preferably, the inwall of described fixed mount is provided with the rubber blanket II.
Preferably, described telescope support comprises stiff end and movable end, and described stiff end is screwed with described fixed mount and is connected, and described movable end and described stiff end are hinged.
Preferably, described fixed mount is made as the semiclosed frame type structure that front end opens wide.
Preferably, the end of described telescope support is made as top tip structure.
The invention has the beneficial effects as follows: owing to the present invention includes the fixed mount and the telescope support that is fixedly connected with described fixed mount of frame type structure, the described fixed mount left and right sides is equipped with fastener, and levelling pole is arranged in the inside casing of described fixed mount by described fastener; During use, first levelling pole is fixed on the described fixed mount by described fastener, and the setting height(from bottom) of described fixed mount can be regulated by described telescope support easy on and off according to the variation of site contour, and in adjustment process, if upper and lower two leveling bubbles of described levelling pole are placed in the middle, just illustrate that current levelling pole position is vertical, can measure operation, thereby greatly reduce the labour intensity of survey crew, improved measuring accuracy and speed, easy to use.

Embodiment
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the present invention relates to a kind of portable level ruler support, present embodiment take with the matching used portable rack of accurate invar bar code levelling pole as example, it comprises the fixed mount 1 and the telescope support 2 that is connected with described fixed mount 1 of frame type structure, described fixed mount 1 rear end is provided with V-structure, described telescope support 2 is fixedly connected with by screw 9 with described V-structure, consists of a reverse V-shaped supporting construction by two described telescope supports 2 thus.The size of described fixed mount 1 is made according to the physical size of accurate invar bar code levelling pole 3, and inwall is circumferentially than accurate invar bar code levelling pole 3 bigger 5mm, is convenient to accurate invar bar code levelling pole 3 is packed in the inside casing of described fixed mount 1.Described fixed mount 1 left and right sides is equipped with fastener, described fastener is preferably holding screw 4, the end of described holding screw 4 is arranged in the inside casing of described fixed mount 1 under the normality, and described accurate invar bar code levelling pole 3 is fixedly installed in the inside casing of described fixed mount 1 by described holding screw 4.The end of described holding screw 4 is provided with rubber blanket I 5, can effectively prevent the surface at the accurate invar bar code levelling pole 3 of 4 damages of holding screw described in described accurate invar bar code levelling pole 3 processes of locking.Inwall at described fixed mount 1 is pasted with rectangular rubber pad II 6; reduced the contact area of accurate invar bar code levelling pole 3 and described fixed mount 1; reach the effect of the accurate invar bar code levelling pole 3 of protection; strengthened combination between accurate invar bar code levelling pole 3 and the described fixed mount 1 thereby also filled slit between described fixed mount 1 inwall and the accurate invar bar code levelling pole 3, guaranteed to combine closely between the two.
Described telescope support 2 comprises stiff end 7 and movable end 8, described stiff end 7 is fixedly connected with by screw 9 with described fixed mount 1, and described movable end 7 and described stiff end 8 are hinged, when obsolete, two described telescope supports 2 can be drawn in together, be convenient to place or carry.
Described fixed mount 1 is made as the semiclosed frame type structure that front end opens wide, and can offer a breach at the front end of described fixed mount 1, reads the numerical value of accurate invar bar code levelling pole 3 portrayals from indentation, there.
The end of described telescope support 2 is made as top 10 structures, is convenient to fix on the ground described telescope support 2.
Use procedure of the present invention is as follows:
Two described telescope supports 2 are opened certain angle and fix on the ground, unclamp described holding screw 4, accurate invar bar code levelling pole 3 is installed on the described fixed mount 1, guarantee that accurate invar bar code levelling pole 3 bottoms are motionless, regulate described telescope support 2 according to site contour situation easy on and off, and swing accurate invar bar code levelling pole 3 all around, until accurate invar bar code levelling pole 3 is upper, lower two round leveling bubbles 11 are placed in the middle, the position that shows accurate invar bar code levelling pole 3 is vertical, guarantee that accurate invar bar code levelling pole 3 is motionless, and be locked and measure by described holding screw 4.
Therefore, by the accurate invar bar code levelling pole 3 of the auxiliary placement of support, can stand vertically and keep stable, reduce the work difficulty of survey crew, avoid improving measuring accuracy and measuring speed because of windage or the artificial measuring error of bringing of helping.The present invention is widely used in the level ruler support field.
