Description
Technical Field
The utility model relates to a bridge detects technical field, specifically is a bridge displacement detection device.
Background
The bridge can be displaced due to the running vehicles and the self reasons thereof, and serious safety accidents can be caused if the detection is not in place and is not timely.
The most common bridge displacement detection method is to reserve a permanent marker on the side face of a bridge and observe the specific numerical value of the bridge displacement through regular measurement, but the method has an obvious disadvantage that the existing permanent marker is mostly small in target, so that certain difficulty exists in observation, and particularly, the phenomenon is obvious when the meteorological conditions are poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bridge displacement detection device to solve the above-mentioned background art and survey the difficulty when the bridge displacement that provides detects, easily receive the problem that meteorological condition influences.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a bridge displacement detection device, includes the box, the box top is provided with the measuring staff, the measuring staff bottom sets up inside the box, measuring staff bottom one side is provided with the rack, the rack meshes with the gear mutually, the gear meshes with the shaft gear mutually, one end is provided with the dial plate on the shaft gear two, the dial plate center is provided with the pointer, the dial plate is provided with the scale all around, the bottom half is provided with the support frame.
Furthermore, an access door is arranged on the box body.

Further, a connecting rod is arranged at one end of the shaft gear, and a pointer is arranged on the connecting rod.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model converts the displacement into the reading of the instrument through the transmission of the rack, the gear and the shaft gear, has stable structure and accurate reading, and is convenient for observation; the transmission structure is arranged in the box body and is not easily influenced by meteorological conditions.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a front view of the present invention;
in the figure: the device comprises a base, a support frame, a box body, a support column 4, a support plate 5, a gear 6, a gear 7, a measuring rod 8, a dial plate 9, scales 10, a pointer 11, a connecting rod 12, an access door 13, a rack 14 and a spring 15.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A bridge displacement detection device comprises a box body 3, wherein a measuring rod 8 is arranged at the top of the box body 3, the bottom end of the measuring rod 8 is arranged in the box body 3, the measuring rod 8 and the box body 3 are in transition fit, and the dead weight of the measuring rod 8 can be balanced by the friction force between the measuring rod 8 and the box body 3; a rack 14 is arranged on one side of the bottom end of the measuring rod 8, the rack 14 is meshed with a gear 7, the gear 7 is meshed with a shaft gear 6, a dial 9 is arranged at one end of the shaft gear 6, a pointer 11 is arranged in the center of the dial 9, scales 10 are arranged on the periphery of the dial 9, a support frame 2 is arranged at the bottom of the box body 3,
furthermore, the box body 3 is provided with an access door 13, so that the maintenance of workers is facilitated.
Further, a supporting plate 5 is arranged at the bottom of the box body 3.
Further, a support column 4 is arranged at the bottom of the box body 3.
Further, the bottom of the support column 4 is provided with a base 1.
Further, the bottom of the measuring rod 8 is provided with a spring 15 which supports the measuring rod 8 and further prevents the measuring rod 8 from moving under the action of self weight.
Further, a connecting rod 12 is arranged at one end of the shaft gear 6, and a pointer 11 is arranged on the connecting rod 12.
The working principle is as follows: when the bridge generates displacement, the measuring rod 8 is driven to displace downwards, the rack 14 on the measuring rod 8 drives the gear 7 to rotate, the gear 7 drives the shaft gear 6 to rotate, the shaft gear 6 drives the connecting rod 12 to rotate, and therefore the pointer 11 is driven to rotate to display the reading.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
