[0031] Embodiment 1:

[0032] The utility model provides bridge deflection monitoring equipment.

[0033] In one embodiment of the utility model, the bridge deflection monitoring equipment includes a deflectometer body 1, a connecting seat 2, a base 3 and a plurality of legs 4. The deflectometer body 1 is detachably mounted on the connecting seat 2. The connecting seat 2 is detachably connected to the base 3. A plurality of inclined grooves 5 are evenly and spaced apart along its circumference. A first slope 6 is formed from top to bottom in the plurality of inclined grooves 5. A plurality of adjustment holes 7 are provided on the base 3 at positions corresponding to the plurality of inclined grooves 5. One ends of the plurality of legs 4 pass through the plurality of adjustment holes 7 one by one and form a second slope 8 abutting against the first slope 6. A limiting component for abutting against the legs 4 is provided in the plurality of inclined grooves 5.

[0034] Specifically, Figures 1 to 7 As shown, in the utility model bridge deflection monitoring device, the monitoring personnel can detachably install the deflectometer body 1 on the connecting seat 2 by means of threaded connection, thereby realizing the stable installation of the deflectometer body 1. Furthermore, since the connecting seat 2 and the base 3 are detachably connected, the detachable connection method can also be threaded connection, so that the connecting seat 2 and the base 3 can be easily disassembled and assembled, so as to assemble, replace and maintain a plurality of legs 4 and the limit assembly, and the structural design is simple and reasonable.

[0035] It can be understood that when there is a protrusion at the placement position of the utility model, since a plurality of inclined grooves 5 are uniformly and spaced along the circumference of the connecting seat 2, a first slope 6 is formed in each of the inclined grooves 5 from top to bottom, and a second slope 8 abutting against the first slope 6 is formed at the upper ends of the plurality of legs 4. At this time, the protrusion at the placement position lifts a certain leg 4 upward, and the leg 4 is relatively displaced with the connecting seat 2 under the action of the first slope 6 and the second slope 8, and radially displaced in the inclined groove 5, thereby preventing the leg 4 from lifting the connecting seat 2 due to the ground protrusion at the placement position. To avoid horizontal tilt of the connecting base 2, the axial movement of the support leg 4 relative to the connecting base 2 is converted into radial movement of the support leg 4 relative to the connecting base 2, thereby realizing automatic leveling of the connecting base 2, so that the connecting base 2 and the deflection meter body 1 are always in a relatively horizontal position. This not only ensures the accuracy of the monitoring results of the deflection meter body 1 and reliable use, but also improves the adaptability of the utility model to different placement positions, and does not require monitoring personnel to perform repeated and tedious leveling operations on the connecting base 2 and the deflection meter body 1, thereby reducing the labor intensity of monitoring personnel and improving monitoring efficiency.

[0036] It is worth mentioning that when the leg 4 moves radially in the inclined groove 5, the limiting component in the inclined groove 5 is always in contact with the leg 4, and the limiting component can be selected as a spring in the prior art. The spring has the characteristics of compact structure, large elastic deformation force, and easy material acquisition. Therefore, it can ensure the stability of the radial movement of the leg 4 without affecting the radial movement of the leg 4 relative to the connecting seat 2 in the inclined groove 5, and the overall structural design is more compact and firm, ensuring that the leg 4 can stably support the connecting seat 2 and the deflection meter body 1.

[0037] In addition, it should be noted that, since a plurality of adjustment holes 7 are provided on the base 3 at positions corresponding to the plurality of inclined slots 5, and the upper ends of the plurality of legs 4 pass through the plurality of adjustment holes 7 one by one in correspondence, in the actual production and manufacturing process of the utility model, the size of the upper ends of the plurality of legs 4 should be larger than the size of the plurality of adjustment holes 7, and smaller than or equal to the size of the notch of the inclined slot 5, thereby not only ensuring that the first slope 6 abuts against the second slope 8, but also preventing the plurality of legs 4 from falling from the adjustment holes 7 and detaching from the base 3; at the same time, when the connecting seat 2 is connected to the base 3, the upper ends of the plurality of legs 4 are all extended into the corresponding plurality of inclined slots 5, at which time the first slope 6 abuts against the second slope 8, and the upper ends of the plurality of legs 4 are pressed down by the connecting seat 2 and abutted by the limit assembly, so that they can be firmly installed in the inclined slot 5, and the structural design is compact, simple and reasonable.

[0038] In one embodiment, specifically, Figures 1 to 6As shown, a limiting protrusion 9 is formed on the groove wall on one side relative to the first slope 6 in any inclined groove 5, and any limiting assembly includes an elastic member 10 and a limiting block 11 for abutting against the supporting leg 4. The elastic member 10 is arranged in the limiting protrusion 9, and the two ends of the elastic member 10 are respectively connected to the groove wall of the inclined groove 5 and the limiting block 11, so that not only can the elastic member 10 be limited by the limiting protrusion 9 to prevent the elastic member 10 from being displaced relative to the connecting seat 2 during compression or rebound, but the limiting block 11 can also be made to always abut against the supporting leg 4 through the elastic member 10 to prevent the supporting leg 4 from moving freely relative to the connecting seat 2.

[0039] In another embodiment, specifically, Figures 1 to 6 As shown, any limit assembly also includes an adjustment column 12, one end of which is connected to the limit block 11, and the other end of which extends in a direction away from the limit block 11 and passes through the connecting seat 2 and the base 3. This embodiment proposes a method for actively adjusting the limit block 11, that is, when the distance that the protrusion in the placement position lifts the support leg 4 upward is short, the monitoring personnel only need to perform horizontal fine-tuning on the connecting seat 2 and the deflection meter body 1. At this time, the monitoring personnel can adjust the distance of the limit block 11 relative to the first slope 6 by screwing the adjustment column 12, thereby achieving fine-tuning of the axial and radial movement distances of the support leg 4, so that the connecting seat 2 and the deflection meter body 1 are always in a relatively horizontal position, which is reliable to use.

[0040] In one embodiment, specifically, Figures 1 to 6 As shown, a third slope 13 is formed on one side of the limit block 11 relative to the first slope 6 , and the slope of the third slope 13 is less than or equal to the slope of the first slope 6 , thereby avoiding interference between the limit block 11 and the first slope 6 , so that the limit block 11 can stably abut against the support leg 4 .

[0041] In one embodiment, any leg 4 includes an adjusting rod 14, a connecting tube 15 and a supporting rod 16 which is movably connected to the connecting tube 15 in a limited position. One end of the adjusting rod 14 passes through the adjusting hole 7 and is provided with a slider 17 for abutting against the first slope 6. A second slope 8 is formed on the side of the slider 17 opposite to the first slope 6. The other end of the adjusting rod 14 extends into the connecting tube 15 and is detachably connected to the connecting tube 15.

[0042] Specifically, Figures 1 to 7As shown, by setting a slider 17 at the upper end of the adjusting rod 14, the adjusting rod 14 can be prevented from falling off from the adjusting hole 7; at the same time, since the second slope 8 is located on the side of the slider 17 relative to the first slope 6, the slider 17 can be stably abutted against the first slope 6. Furthermore, when the monitoring personnel place the utility model, since the support rod 16 is connected to the connecting tube 15 by limited rotation, the support rod 16 can swing relative to the connecting tube 15, that is, the plurality of legs 4 are rotated in a direction away from the deflection meter body 1 and arranged to expand outward, thereby improving the placement stability of the utility model, and the structural design is simple and reasonable. Furthermore, the limited rotation connection between the support rod 16 and the connecting tube 15 can be a bolt connection with a hand wheel, that is, the rotation and locking of the support rod 16 can be achieved by screwing the hand wheel, which is simple and convenient to operate. It can be understood that when the height difference of the placement positions of several legs 4 is large, since the lower end of the adjusting rod 14 extends into the connecting tube 15 and is detachably connected to the connecting tube 15, the detachable connection method can be a snap-on or threaded connection, so that the length of a single leg 4 can be adjusted for a larger stroke, which can not only adapt to the placement position with a large height difference, but also can adjust the overall height of the base 3, the connecting seat 2 and the deflection meter body 1 and other components.

[0043] In one embodiment, a column 18 is vertically arranged on the bottom surface of the base 3, a sleeve 19 and a slide cylinder 20 are slidably mounted on the column 18 and the support rod 16, a connecting rod 21 is hinged between the sleeve 19 and the slide cylinder 20, and an end cap 22 is detachably mounted on the end of the column 18 away from the base 3. It can be understood that if Figures 1 to 3 As shown, the connecting rod 21 is hinged with the sleeve 19 and the slide cylinder 20 to enable synchronous rotation of the plurality of legs 4, thereby achieving simultaneous expansion or contraction of the plurality of legs 4. There is no need to rotate the plurality of legs 4 in sequence, thereby reducing the number of rotations of the support rod 16, facilitating operation, and improving monitoring efficiency.

[0044] In one embodiment, a bubble level 23 is provided on the connection base 2. It can be understood that Figure 1 As shown, by setting the bubble level 23 on the connecting base 2, the staff can intuitively check the real-time position status of the connecting base 2 and the deflection meter body 1, which is convenient for leveling the deflection meter body 1.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
