Abstract
The utility model discloses an assisted pasting and dismantling device for a bridge monitoring vibrating wire sensor. The device is formed by telescopic rods, fixtures, electromagnets, springs, a round rolling shaft, a connecting strip, sleeves, cap nuts and the like. The assisted pasting and dismantling device is characterized in that the vibrating wire sensor can be pasted and dismantled at the position of a beam bottom or a beam edge 1-2m higher than the top of the head of a monitoring person, and efficiency of bridge monitoring preliminary work is improved. The assisted pasting and dismantling device has the advantages that the structure is simple; the device can be contracted and can not occupy oversize space; the device is convenient to use and facilitates application in practical projects.
Description
Technical field
The utility model belongs to bridge monitoring field, particularly a kind of bridge monitoring vibrating wire sensor auxiliary sticking and detaching device.
Background technology
In bridge monitoring, usually to use the physical quantitys such as strain of sensor measurement structure, its method has the foil gauge of subsides mensuration, vibrating wire sensor mensuration, and because condition is comparatively severe at the construction field (site), stickup foil gauge is consuming time, effort, and vibrating wire sensor is pasted comparatively simple and easy and speed, therefore the present more use vibrating wire sensor mensuration in job site.
Bridge strain measurement point mainly concentrates on Liang Tishang, and beam body is generally higher apart from ground, need to set up scaffold, to facilitate stickup vibrating wire sensor, and due to construction condition is poor or the construction period is tighter reason, setting up of scaffold is comparatively simple and crude, often in scaffold top, at the bottom of beam, still have certain distance, now need monitor staff to set up the stickup that ladder carries out vibrating wire sensor, there is great risk, reduced the efficiency of monitoring work, after project monitoring, carry out the dismounting work of sensor, now, still need again to set up ladder, monitor staff's safety is caused to very large hidden danger.
Utility model content
For above-mentioned technical problem, the utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of bridge monitoring vibrating wire sensor auxiliary sticking and detaching device, solve stickup and the dismounting problem of vibrating wire sensor in bridge monitoring process, ensure the personal safety of monitor staff in monitor procedure, improve the efficiency of monitoring, guarantee the smooth construction of engineering.
For reaching the purpose of this utility model, the technical scheme of employing is as follows:
A kind of bridge monitoring vibrating wire sensor auxiliary sticking and detaching device, it is characterized in that: comprise expansion link, fixture, electromagnet, spring, circle roller bearing, connection strap, sleeve, blind nut, described sleeve is justified roller bearing and is run through rear two ends and screwed and formed a whole by blind nut, connection strap connects two pairs of sleeves, on described sleeve, be provided with clampingly the fixture can opening and closing part forming by two, one end of described fixture is provided with electromagnet, described spring be arranged at two can adhesive portion between, described expansion link is vertically connected with circle roller bearing by screw thread.
Further, described expansion link from top to bottom comprise successively by screw thread and circle roller bearing the first expansion link connected vertically, take in the first expansion link the second expansion link, take in the 3rd expansion link of the second expansion link.
Further, the material of described the first expansion link, the second expansion link, the 3rd expansion link, circle roller bearing, connection strap is aluminium alloy, and quality is light, convenient operation and carrying.
Further, the material of described fixture is copper.
Further, the material of described sleeve, blind nut is vinyon.
The operation principle of bridge monitoring vibrating wire sensor auxiliary sticking and detaching device is, in the time of need to pasting vibrating wire sensor, by vibrating wire sensor two clamp clamps, expansion link is pulled out completely, at vibrating wire sensor two, be stained with glue, then at the bottom of vibrating wire sensor being sticked on to beam or beam edge, then start the switch of electromagnet, fixture is unclamped, when needs are removed vibrating wire sensor, only need grip alignment vibrating wire sensor two, close the switch of electromagnet, pull gently expansion link end, until sensor is separated with bridge.
Compared with prior art, the beneficial effects of the utility model are: by utilizing auxiliary sticking and detaching device, can realize at the bottom of than the beam of the high 1 ~ 2m in the monitor staff crown or beam edge is pasted and removes vibrating wire sensor, improve the efficiency of bridge monitoring previous work, its advantage is simple in structure, can shrink unobstructive, easy to use, be convenient to apply in Practical Project.
