[0026] According to an embodiment of the utility model, a mobile formwork deformation monitoring device for bridge construction is provided.

[0027] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] The working principle of the moving component 5 is as follows: when the monitoring position of the deformation monitoring component 7 needs to be moved, the servo motor 501 is started through the external controller, and then the screw rod 502 is rotated under the action of the servo motor 501, and during the rotation, the sliding plate 504 on the outside is driven to move inside the installation box 4. During the movement, the connecting frame 505 on the outside of the sliding plate 504 is linked to move with it, thereby achieving the purpose of changing the monitoring position of the deformation monitoring component 7 at the top of the connecting frame 505.

[0030] In one embodiment, for the above-mentioned adjustment component 6, the adjustment component 6 includes a protective box 601 installed on the top of the connecting frame 505, and a servo motor 2 602 is arranged inside the protective box 601, and the output shaft of the servo motor 2 602 is provided with a rotating shaft 603, and a gear 1 604 is arranged on the outer side of the rotating shaft 603; a gear 2 605 meshing with the gear 1 604 is arranged on one side of the gear 1 604, and a rotating frame 607 is arranged in the middle of the gear 2 605 through a connecting shaft 606, so that the monitoring angle or position can be adjusted without dismantling and moving the deformation monitoring component 7, avoiding interference with the pouring of concrete during bridge construction, thereby ensuring the smooth progress of the construction work, improving the efficiency and safety of monitoring, and ensuring the construction quality and long-term stability of the structure.

[0031] The working principle of the adjustment component 6 is as follows: when it is necessary to pour concrete inside the bridge formwork 3, in order to avoid the deformation monitoring component 7 from affecting the top of the bridge formwork 3, the servo motor 2 602 is started through an external controller, and then the gear 1 604 is driven to rotate under the action of the servo motor 2 602, and in the process of rotation, it rotates together with the gear 2 605, and then under the action of the gear 2 605, the rotating frame 607 rotates on the outside of the connecting shaft 606, and finally the deformation monitoring component 7 on one side of the rotating frame 607 can be rotated to an idle area to avoid affecting the pouring of concrete.

[0032] In one embodiment, for the above-mentioned deformation monitoring component 7, the deformation monitoring component 7 includes a support frame 701 installed on one side of the rotating frame 607, the bottom end of the support frame 701 is connected to the rotating frame 607 through a support rod 702, a sliding cavity 1 703 is provided inside the support frame 701, and two groups of hydraulic rods 1 704 are arranged inside the sliding cavity 1 703; a sliding rod 1 705 is provided on one side of the hydraulic rod 1 704, a sliding cavity 2 706 is provided inside the sliding rod 1 705, a sliding cavity 2 707 is arranged inside the sliding cavity 2 706, and a hydraulic rod 2 708 is arranged inside the sliding rod 2 707; a connecting rod 709 is provided on one side of the sliding rod 2 707, and the connecting rod 709 is provided on one side of the sliding rod 2 707. A laser measuring instrument 710 is arranged at the bottom end of 09, and triangular grooves 711 are symmetrically provided inside the sliding cavity 1 703 and the sliding cavity 2 706, and triangular bars 712 matching with the triangular grooves 711 are arranged on the outer sides of the sliding rod 2 707 and the sliding rod 1 705, so that the laser measuring instrument 710 can be driven to move from one end of the bridge template 3 to the other end under the action of the hydraulic rod 2 708 and the hydraulic rod 1 704, and the distance between the laser measuring instrument 710 and the boundary of the bridge template 3 is extended, so as to realize the measurement of various positions on the same horizontal line of the bridge template 3, and at the same time, it can cooperate with the moving component 5 to measure the flatness of the surface of each position of the bridge template 3 to determine whether it is deformed.

[0033] It should be explained that the main principle of using the laser measuring instrument 710 to detect the flatness of the bridge template 3 to determine whether there is deformation is as follows:

[0034] The working principle of the laser measuring instrument 710 is to use the emission, propagation and reception of laser beams to measure the distance and position of the target object. The laser measuring instrument 710 mainly includes a laser, a transmitter, a receiver and an electronic controller. The laser beam is irradiated onto the bridge template 3, part of the laser energy is absorbed by the target object, and part of the laser is reflected back. The receiver receives the reflected laser and converts it into an electrical signal, so that the distance between the target object and the rangefinder can be calculated.

[0035] Specific steps:

[0036] The laser measuring instrument 710 first emits a highly focused, straight laser beam, which serves as the reference line for measurement. After the laser is emitted from the transmitter, it directly irradiates the surface of the bridge template 3. The receiver of the laser measuring instrument then captures the reflection signal of the laser beam on the measured surface. The processing unit inside the laser measuring instrument 710 analyzes the received laser data, especially calculates the offset of the laser beam caused by the uneven surface. These offsets will then be converted into plane height difference values ​​to quantify the unevenness of the plane.

[0037] The working principle of the deformation monitoring component 7 is as follows: when measuring the flatness of the surface of the bridge template 3 to determine whether it is deformed, first measure the boundary position of the bridge template 3 through the laser measuring instrument 710 on one side of the support frame 701, and then start the hydraulic rod 1 704. Under the elongation of the hydraulic rod 1 704, the sliding rod 1 705 inside the support frame 701 is driven to move outward inside the sliding cavity 1 703, and during the movement, the laser measuring instrument 710 is also driven to move outward, so that the laser measuring instrument 710 can detect the bridge template 3 away from the boundary position. After the movement of the sliding rod 1 705 reaches the limit, start the hydraulic rod 2 708. Under the elongation of the hydraulic rod 2 708, the sliding rod 2 707 inside the sliding cavity 2 706 is driven to move outward, so that the distance between the laser measuring instrument 710 and the boundary of the bridge template 3 can be extended again, so as to realize the measurement of various positions on the same horizontal line of the bridge template 3. At the same time, it can cooperate with the moving component 5 to measure the flatness of the surface of each position of the bridge template 3 to determine whether it is deformed.

[0038] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0039] In actual application, the staff installs the support beam 2, the cross beam 1, the bridge formwork 3 and the other components of the mobile formwork according to the construction requirements, and sets the installation box 4, the moving component 5, the adjustment component 6 and the deformation monitoring component 7 on the top of the support beam 2. After the overall installation is completed, the laser measuring instrument 710 is moved from one end of the bridge formwork 3 to the other end using the moving component 5 and the deformation monitoring component 7, so as to continuously measure the flatness signal of the bridge formwork 3 on the same horizontal line, and send the flatness signal to the processor to analyze the consistency of the signal, and analyze whether the surface of the bridge formwork 3 is uneven according to the consistency result, and judge whether the bridge formwork 3 is deformed based on the flatness analysis (the working principle of the laser measuring instrument 710 is shown above).

[0040] If there is deformation, a reminder is sent to the staff to adjust the bridge formwork 3 to prevent the deformed bridge formwork 3 from affecting the quality of the bridge. If there is no deformation, concrete is directly poured inside the bridge formwork 3 to construct the bridge. Before pouring, the deformation monitoring component 7 is moved to an idle area through the adjustment component 6 to avoid interfering with the pouring, and also to prevent the concrete from damaging the laser measuring instrument 710.

[0041] In summary, with the aid of the above technical solution of the utility model, the utility model has a simple structure and is easy to operate. By setting the adjustment component 6, the monitoring angle or position can be adjusted without removing and moving the deformation monitoring component 7, thereby avoiding interference with the pouring of concrete during bridge construction, thereby ensuring the smooth progress of construction operations, improving the efficiency and safety of monitoring, and ensuring the construction quality and long-term stability of the structure. The utility model can drive the deformation monitoring component 7 to move between the two groups of support beams 2 under the driving action of the servo motor 501 by setting the moving component 5, and can adaptively move the deformation monitoring component 7 according to the length of the bridge template 3, so as to achieve the purpose of fully covering all positions of the bridge template 3 and improve the comprehensiveness and flexibility of monitoring. The utility model is provided with a deformation monitoring component 7, which can drive the laser measuring instrument 710 to move from one end of the bridge template 3 to the other end under the action of the hydraulic rod 2 708 and the hydraulic rod 1 704, thereby extending the distance between the laser measuring instrument 710 and the boundary of the bridge template 3, and realizing the measurement of various positions on the same horizontal line of the bridge template 3. At the same time, it can cooperate with the moving component 5 to measure the flatness of the surface of each position of the bridge template 3 to determine whether it is deformed.
