Abstract

The utility model discloses a bridge detection displacement pre-stressing device. A bolt A (3) is engaged with an internal thread on the end wall of a socket (2), inserted into a pre-tensioning rod hole A (8) and connected with one end of a held spring A (5), and the other end of the spring A (5) is connected with an inserted pre-tensioning rod A (13); a bolt B (4) is engaged with an internal thread on the other end wall of the socket (2), inserted into a pre-tensioning rod hole B (10) and connected with one end of a held spring B (6), and the other end of the spring B (6) is connected with an inserted pre-tensioning rod B (15); and a working rod (14) is inserted into a working hole (9). The bridge detection displacement pre-stressing device is simple and compact in structure, convenient to manufacture and install, flexible in operation and low in cost, and can be used for effectively detecting the variable sinking value of a structural section point position of a bridge under any environmental condition.

Description

Bridge detects the pre-power apparatus of displacement

Technical field

The utility model relates to pick-up unit, and especially a kind of bridge detects the pre-power apparatus of displacement.

Background technology

In order to use bridge safely, should often detect bridge, distortion, flexure, horizontal translation to each cross section point position of bridge structure detects exactly, for the heavy construction project, adopt spirit-leveling instrument, transit to detect, its precision is not high, and uses advanced measuring technologies such as total powerstation, GPS, high-precision laser spirit-leveling instrument, but equipment price is expensive, technique device is complicated, technical requirement is high, is difficult to carry out large-scale conventional bridge and detects; At present adopting dial gauge, clock gauge is the detection of the sensor of benchmark, also is the technological means the most accurate, the most reliable, that cost is low, and obtain technical manual should.Need the field to set up the certain altitude shelf, dial gauge or clock gauge are installed in detection, it is unusual difficult setting up shelf for the field, the weak points such as effort, cost height of taking a lot of work.

Summary of the invention

At above-mentioned existence, to remove from and set up shelf, the purpose of this utility model provides bridge a kind of simple in structure, easy to use and detects the pre-power apparatus of displacement.

Technical scheme that the purpose of this utility model adopts is to comprise that forming whole plug one end has lower draw-bar, the other end that pre-pull bar A, working beam, pre-pull bar B are arranged successively; Forming whole socket one end has the hook of going up, the other end that pre-tie rod hole A, working hole, pre-tie rod hole B are arranged successively, and there is vertical displacement meter device through hole the centre, and described working hole is communicated with displacement meter device through hole; Its bolt A and the engagement of socket end wall internal thread, and insert in the pre-tie rod hole A hole, being connected with placement spring A one end, the spring A other end is connected with the pre-pull bar A of insertion; Another end wall internal thread engagement of bolt B and socket, and insert in the pre-tie rod hole B hole, being connected with placement spring B one end, the spring B other end is connected with the pre-pull bar B of insertion; Working beam inserts in the working hole hole.

The utility model course of work, hooking device is on the bridge pick-up unit on earlier will be of the present utility model, to have dial gauge to be contained in the displacement counter device through hole, the dial gauge contact is towards the working beam direction, and lower draw-bar has hung weight, flexure if take place in bridge during detection, this moment, the bridge pick-up unit also moved down phenomenon, socket is moved down, and hundred bit table De Touch Tou, Touch was to the working beam end face, hundred bit table numerals are also changed, detect thereby can calculate the bridge deflection value.

The utlity model has simple and compact for structurely, fabrication and installation are convenient, flexible operation, and cost is low, can effectively measure the heavy value detection of change that bridge is in structural section point position under any environmental baseline.
