Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a verticality testing device for bridge acceptance. Background Technology

[0002] Verticality testing during bridge acceptance is a crucial step in ensuring the verticality of vertical components such as bridge towers and piers. It is generally done by measuring the actual deviation using a plumb line and comparing it with design requirements and standards to determine whether the structure tilts beyond the limit. This directly determines whether it affects the overall stability and safety of the bridge and is one of the core indicators that must be passed during acceptance.

[0003] Chinese patent discloses a verticality testing device for building inspection (publication number: CN214748011U). This device features a slider within a groove, a locking block on the other side of a moving plate, a push plate adapted to the locking groove within its inner cavity, and a connecting rod on the other side of the push plate. This allows the device to measure walls of different heights, further expanding its applicability. However, this device also has the following drawbacks:

[0004] The measuring bracket in the above-mentioned device has a simple structure and supports both the connecting rope and the plumb bob. When the operator uses the measuring bracket to inspect the bridge, they can only hold the measuring bracket with one hand. It is inconvenient to turn their head to read the protractor data when holding it with both hands, and they are prone to bumping into the connecting rope and the plumb bob. Therefore, a verticality testing device for bridge acceptance is proposed to solve the above problems. Utility Model Content

Figure 4 As shown, the winding rope 204 can be a soft steel wire rope.

[0026] The testing mechanism 1 includes a measuring bracket 101. The lower inner wall of the measuring bracket 101 is inserted into a second extension plate 201. A knob 111 is provided on the back of the measuring bracket 101 and above the second extension plate 201. A threaded rod 112 is fixedly connected to the center of the bottom surface of the knob 111. The lower end of the threaded rod 112 is connected through the measuring bracket 101, and the bottom end of the threaded rod 112 is inserted into and threadedly fastened to a second threaded hole 205. Figure 1 As shown, the threaded rod 112 is simultaneously inserted into the measuring bracket 101 and the second extension plate 201.

[0027] A first extension plate 106 is fixedly installed on the lower end of the side of the measuring bracket 101 away from the second extension plate 201. A first handle 107 is fixedly installed on the surface of the first extension plate 106. A through hole 108 is also opened in the middle of the surface of the first extension plate 106. The side of the first extension plate 106 away from the first handle 107 abuts against the second extension plate 201, and the threaded rod 112 is connected through the through hole 108. The surface of the first extension plate 106 abuts against the knob 111. The end of the threaded rod 112 is also inserted into the first threaded hole 203 and threadedly fastened. Figure 4 , Figure 5 As shown, the threaded rod 112 is simultaneously inserted into the first extension plate 106 and the second extension plate 201.

[0028] The lower end of the measuring bracket 101 is connected to two winding ropes 204. A split chuck 109 is fixedly installed on the surface of the measuring bracket 101 and outside the winding ropes 204. A threaded clamping sleeve 110 is threaded onto the outer surface of the split chuck 109. The middle part of the surface of the threaded clamping sleeve 110 abuts against the split end surface of the split chuck 109. Figure 3 As shown, the split end of the split chuck 109 is frustum-shaped, and the other end of the split chuck 109 is threaded.

[0029] The testing mechanism 1 includes a measuring bracket 101. A crossbeam 104 is fixedly mounted on the middle of the surface of the measuring bracket 101. A protractor 105 is fixedly connected to the bottom surface of the crossbeam 104 and the end away from the measuring bracket 101. Figure 1 As shown, when the connecting line 102 falls vertically, the connecting line 102 coincides with the 90-degree mark in the middle of the protractor 105.

[0030] The measuring bracket 101 is located on the bottom surface above the middle of the protractor 105, and a connecting line 102 is embedded and fixed thereon. The lower end of the connecting line 102 is connected through the crossbeam 104, and the bottom end of the connecting line 102 extends to the bottom of the protractor 105 and is fixedly connected to a plumb bob 103.

[0031] The working principle of this utility model:

[0032] When the device is in use, the operator uses the first handle 107 and the second handle 202 to press the measuring bracket 101 against the surface of the bridge test point. When the connecting line 102 hangs freely and stops shaking, the operator reads the degree of overlap between the connecting line 102 and the surface of the protractor 105, thereby determining whether the measuring bracket 101 and the surface of the bridge test point are perpendicular.

[0033] Next, by turning knob 111, the threaded rod 112 is separated from the measuring bracket 101, and the second extension plate 201 can be removed from the lower end of the measuring bracket 101. The second extension plate 201 then wraps around the bridge support once, as shown... Figure 4 As shown, the side of the second extension plate 201 abuts against the back of the first extension plate 106, and the threaded rod 112 can pass through the through hole 108 and be screwed and fixed inside the first threaded hole 203, thereby fixing the side of the second extension plate 201 to the first extension plate 106. At the same time, the winding rope 204 is wrapped around the outside of the bridge support. Then, the end of the winding rope 204 on one side of the first extension plate 106 is pulled to tighten the winding rope 204 on the outside of the bridge support. Finally, the threaded clamping sleeve 110 outside the split clamp 109 is screwed, and the inner wall of the threaded clamping sleeve 110 abuts against the split area of ​​the split clamp 109, so that each split is gathered and clamped to the winding rope 204. Thus, the winding rope 204 is fixed relative to the measuring bracket 101, and the measuring bracket 101 is tied and fixed relative to the bridge, which facilitates the operator to read the protractor.
