Abstract
The utility model provides a kind of novel observation pier for retainer instrument, comprising: pier body, the thoughts of returning home device be connected with described pier body one end and the fixed head be connected with the described pier body other end; The connecting link that described thoughts of returning home device comprises circular slab, is arranged on the circular port of described circular slab central authorities and is connected with described circular port, described circular port is provided with screw thread, connecting link is provided with positive/negative thread, one end of described connecting link is connected with described circular port, the other end is connected the utility model and had both met venue restriction and the normal requirement used with surveying instrument, overcome again " three the is fixed " principle of the deformation monitoring that tripod can not meet; Simultaneously because the utility model is detachably reused, significantly save cost and improve service efficiency.
Description
Technical field
The utility model relates to the device of fixed observer instrument in observation field, particularly relates to a kind of novel observation pier for retainer instrument.
Background technology
Detect in rack installation, amount of deflection and in the deformation monitoring process of the heavy constructions such as dam, bridge and railway foundation, all need to adopt " three is fixed " requirement that forced centering fixed observer pier is fixed with satisfied monitoring route, instrument is fixed, personnel fix.
At present, tradition fixed observer pier adopts reinforced concrete structure, in rack amount of deflection test item, adopt traditional fixed observer pier to there is limitation, be mainly manifested in be limited by have grid structure venue restriction and fixed observer pier pouring, dismounting inconvenience, affect construction speed, the fixed observer pier of simultaneously concrete casting also also exists that fabrication cycle is long, cost is high and the problem such as not reproducible use.Also have and adopt tripod to be that support instrument applicator platform carries out observing, but tripod can not meet " three the is fixed " principle in observation process, and the error in measurement of tripod height is the main source of vertical error.
Nowadays lack a kind of requirement that namely will meet long term monitoring, can not be affected again it and use normally, simultaneously reusable fixed observer pier again.
Utility model content
The utility model is intended at least solve one of Problems existing in background technology.
For this reason, one of the purpose of this utility model is to provide a kind of reusable novel observation pier for retainer instrument.
The utility model takes following technical scheme: the fixed head that it comprises pier body, the thoughts of returning home device be connected with described pier body one end and is connected with the described pier body other end; The connecting link that described thoughts of returning home device comprises circular slab, is arranged on the circular port of described circular slab central authorities and is connected with described circular port, described circular port is provided with screw thread, connecting link is provided with positive/negative thread, and one end of described connecting link is connected with described circular port, and the other end is connected with surveying instrument.
Further, described fixed head is provided with through hole; Described through hole is connected with expansion bolt, fixing whole device.
The beneficial effects of the utility model are, provide a kind of novel observation pier for retainer instrument, and the utility model had both met venue restriction and the normal requirement used, and overcome again " three the is fixed " principle of the deformation monitoring that tripod can not meet; Simultaneously because the utility model is detachably reused, significantly save cost and improve service efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment for the novel observation pier of retainer instrument.
Embodiment
Hereafter will describe the utility model in detail in conjunction with specific embodiments.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.
Embodiment of the present utility model is described in detail: the fixed head 3 that it comprises pier body 1, the thoughts of returning home device 2 be connected with described pier body 1 one end and is connected with described pier body 1 other end below in conjunction with Fig. 1; The connecting link 23 that described thoughts of returning home device 2 comprises circular slab 21, is arranged on the circular port 22 of described circular slab 21 central authorities and is connected with described circular port 22, described circular port 22 is provided with screw thread, connecting link 23 is provided with positive/negative thread, one end of described connecting link 23 is connected with described circular port 22, and the other end is connected with surveying instrument; Described fixed head 3 is provided with through hole 31; Described through hole 31 is connected with expansion bolt, fixing whole device.
In the utility model embodiment, described pier body 1 can use steel construction, highly can determine according to actual conditions; Described circular port 23 is for fixed observer equipment; Described fixed head 3 can be square, also can be circular; Described through hole 31 also can be threaded hole; Because the utility model is connected with concrete mostly, so usually use expansion bolt to be connected with concrete.
The utility model embodiment provides a kind of novel observation pier for retainer instrument, and the present embodiment had both met venue restriction and the normal requirement used, and overcomes again " three the is fixed " principle of the deformation monitoring that tripod can not meet; Simultaneously because the present embodiment is detachably reused, significantly save cost and improve service efficiency.
In description of the present utility model, term " connection " and " fixing " etc. all should be interpreted broadly, and such as, " connection " can be fixedly connected with, and also can be removably connect, or connects integratedly; Can be direct connection, also can be indirectly connected by intermediary.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
