More specifically, when the fixing device is used, after the fixing of the lower surface of the sucker 6 and the bridge 1 is completed, as shown in fig. 1 and 2, the motor 7 is started to drive the threaded rod 19 to start rotating, and since the surface of the threaded rod 19 is provided with two sections of oppositely arranged thread grooves, the rotation of the threaded rod 19 drives the two moving blocks 8 to move towards the direction close to each other, the opposite movement of the two moving blocks 8 can enable the two connecting rods 15 and the two fixing blocks 16 to move towards the direction close to each other, so that the two clamping plates 4 move towards the direction close to each other until the two clamping plates 4 are in contact with the surface of the bridge pier 2, at this time, along with the continued movement of the two moving blocks 8, the first spring 17 between the clamping plates 4 and the fixing blocks 16 can be compressed, and simultaneously the telescopic rod 18 can shrink, and under the action of the elastic potential energy of the first spring 17, the clamping fixing device can enable the two clamping plates 4 to complete the clamping fixing of the bridge pier 2, and is simple to operate and good in fixing effect.
Under the action of the telescopic rod 18, the first spring 17 can be prevented from tilting when being compressed, so that the service life of the first spring 17 is prolonged.
It should be noted that, as shown in fig. 3, in this case, the two moving blocks 8 are in a state when they are not moving, and the two abutting blocks 34 in this state are abutted against the moving block two 29 and the hinge block 26 in the middle, that is, the moving block two 29 and the hinge block 26 do not slide in the limiting frame 31, so that the upper suction cup 6 cannot easily move and deflect, and the deflection of the pointer one 23 on the gear ring 25 and the scale two 36 on the gear two 39 when the suction cup 6 is not fixed with the bridge 1 is avoided, so that the problem of detection error before the bridge 1 is detected in displacement is avoided, and the accuracy of the detection result when the bridge 1 is detected in subsequent displacement is ensured.
After the fixing of the suction cup 6 is completed, along with the opposite movement of the first moving block 8, under the action of the two hinge plates 40, the two abutting blocks 34 can move reversely, so that the two abutting blocks 34 can not limit the second moving block 29 and the hinge block 26 in the middle, that is, the second moving block 29 can slide in the limiting frame 31 at the moment, and meanwhile, the hinge block 26 can deflect relative to the second moving block 29.
After the bridge 1 is displaced in the front-rear direction, the suction cup 6 is synchronously displaced by the displacement of the bridge 1, namely, the suction cup 6 is displaced in the front-rear direction relative to the fixed frame 3 below, so that the hinge block 26 and the hinge rod 30 deflect relative to the second support plate 28, the deflection of the hinge rod 30 drives the first gear 27 to start rotating, the rotation of the first gear 27 drives the gear ring 25 meshed with the first gear 27 to start rotating, the rotation of the gear ring 25 enables the first pointer 23 to start rotating, the position of the first graduated scale 22 pointed by the first pointer 23 can be changed, and a worker can determine the distance of the front-rear displacement of the bridge only by periodically observing the position of the first graduated scale 22 pointed by the first pointer 23, so that the bridge 1 can be maintained conveniently.
When the bridge 1 is displaced in the left-right direction, the suction cup 6 is driven to move in the left-right direction synchronously, the movement of the suction cup 6 can make the hinge block 26 and the second support plate 28 below move in the left-right direction, and the movement of the second support plate 28 can make the second moving block 29 slide in the limiting frame 31.
As shown in fig. 5, the movement of the second moving block 29 drives the second connecting rod 32 to slide in the rectangular notch 33, the movement of the second connecting rod 32 causes the rack row 35 to start moving, the movement of the rack row 35 drives the second gear 39 meshed with the rack row to rotate, and the rotation of the second gear 39 drives the second scales 36 on the surface to rotate, so that the position of the second scales 36 pointed by the second pointer 38 is changed, and a worker only needs to periodically observe the position of the second scales 36 pointed by the second pointer 38, so as to determine the distance of the bridge front-rear displacement.
When the bridge 1 is subject to sedimentation, as shown in fig. 1 and 3, the downward movement of the bridge 1 drives the suction cup 6 to move downward, the movement of the suction cup 6 causes the first disk 43 to slide downward in the sleeve 44, meanwhile, the third spring 42 is compressed, that is, the elastic potential energy of the third spring 42 is increased, the pressure on the lower pressure sensor 41 is increased along with the increase of the elastic potential energy of the third spring 42, the pressure sensor 41 transmits the increased pressure value to the mobile phone or the computer of the inspector in time, the inspector can immediately know that the bridge 1 is subject to sedimentation, and the pressure sensor 41 is based on real-time detection of the internet of things, which is a more mature prior art.
Because bridge 1 subside the phenomenon and compare in the displacement in the horizontal direction, dangerous degree is higher, serious still can lead to the bridge floor subsidence, consequently bridge 1 subside be directly put through pressure sensor 41 based on the thing networking remind the staff at the first time, after the staff knows, can arrive the position department of bridge 1 of subsidence in the first time, maintain bridge 1, and the dangerous degree when bridge 1 takes place horizontal displacement is relatively less, consequently only need the staff regular go on site observation can.
Working principle: this bridge construction bridge displacement detection device, when using, the fixed frame 3 of inspection personnel hand, supports the sucking disc 6 of fixed frame 3 top through external jacking equipment and is accurate lower surface of bridge 1, opens suction fan 5 afterwards, under suction fan 5's effect, can suck the gas in the sucking disc 6 through breathing pipe 13 promptly, and sucking disc 6 at this moment can fix in the below of bridge 1 promptly.
After the fixation of the lower surface of the sucking disc 6 and the bridge 1 is completed, the motor 7 is started, the threaded rod 19 is driven to start to rotate, so that the two clamping plates 4 move towards the direction close to each other until the two clamping plates 4 are in butt joint with the surface of the bridge pier 2, the first spring 17 between the clamping plates 4 and the fixed block 16 can be compressed along with the continued movement of the first moving block 8, and at the moment, the clamping and fixing of the bridge pier 2 can be completed by the two clamping plates 4 under the action of elastic potential energy of the first spring 17, so that the operation is simple, and the fixing effect is good.
As shown in fig. 3, in the state when the two first moving blocks 8 are not moved, the two abutting blocks 34 in the state are abutted against the second moving block 29 and the hinge block 26 in the middle, that is, the second moving block 29 and the hinge block 26 cannot slide in the limiting frame 31, so that deflection of the first pointer 23 on the gear ring 25 and the second graduated scale 36 on the second gear 39 when the suction cup 6 is not fixed with the bridge 1 is avoided, the problem of detection error before displacement detection of the bridge 1 is avoided, and accuracy of detection results when the bridge 1 is subsequently detected in displacement is ensured.
After the suction cup 6 is fixed, the two support blocks 34 can be reversely moved to separate from the second moving block 29 and the hinge block 26 under the action of the two hinge plates 40 along with the opposite movement of the first moving block 8, and the second moving block 29 can slide in the limiting frame 31 at this time, and the hinge block 26 can also deflect relative to the second moving block 29.
When the bridge 1 is displaced in the front-rear direction, the suction disc 6 is driven to displace synchronously, so that the hinge block 26 and the hinge rod 30 deflect relative to the second support plate 28, and the first gear 27 and the gear ring 25 are driven to rotate, so that the first pointer 23 rotates, the position of the first scale 22 pointed by the first pointer 23 can be changed, and a worker can determine the distance of the bridge front-rear displacement by only periodically observing the position of the first scale 22 pointed by the first pointer 23, so that the bridge 1 can be maintained later.
After the bridge 1 is displaced in the left-right direction, the suction disc 6 is driven to synchronously move in the left-right direction, so that the second moving block 29 slides in the limiting frame 31, and the second connecting rod 32 and the rack row 35 are driven to synchronously move, so that the second gear 39 rotates, the position of the second graduated scale 36 pointed by the second pointer 38 can be changed, and a worker can determine the distance of the bridge front-back displacement by only periodically observing the position of the second graduated scale 36 pointed by the second pointer 38.
When the bridge 1 is subjected to sedimentation, the suction disc 6 is driven to move downwards after the bridge moves downwards, the disc one 43 is driven to slide downwards in the sleeve 44, meanwhile, the spring three 42 is compressed, namely, the elastic potential energy of the spring three 42 is increased, the pressure born by the pressure sensor 41 below is increased along with the increase of the elastic potential energy of the spring three 42, the pressure sensor 41 can timely transmit the increased pressure value to a mobile phone or a computer of a detector, and the detector can immediately know that the bridge 1 is subjected to sedimentation.
Because the settlement phenomenon of the bridge 1 is higher in danger degree and serious in the sinking of the bridge deck possibly caused compared with the displacement in the horizontal direction, the settlement of the bridge 1 is realized by directly connecting the pressure sensor 41 to remind workers of maintaining the bridge 1 at the first time based on the Internet of things, and the danger degree of the bridge 1 in the horizontal displacement is relatively smaller, so that the workers only need to regularly go to the site for observation.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
