DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Please refer to Figures 1-5 A road and bridge vertical detection device, including the base table 2 of installing three supports 1, the middle part of base table 2 is connected with bolt 6 and slides, the upper surface of base table 2 is provided with measuring mechanism 4, measuring mechanism 4 includes angle measuring module (horizontal / vertical angle sensor), distance measuring module (laser emitter and receiver), data processing unit and coaxial telescope (integrated distance measuring light path and sighting light path) that can realize target point accurate positioning;

[0024] The bottom surface of measuring mechanism 4 is fixedly connected with bottom plate 5, the inner wall of the middle part of bottom plate 5 is threadedly connected with the upper end of bolt 6, the two sides of bottom plate 5 are connected with anti-drop assembly, the upper surface of base table 2 is fixedly connected with U-shaped frame 3, the two sides of U-shaped frame 3 are connected with reset assembly that can be extruded and limited with two anti-drop assemblies respectively.

[0025] As Figures 1 to 5As shown, the road bridge vertical detection device in the utility model, first three supports 1 are expanded to three directions, and then the stability of the base table 2 can be guaranteed, and subsequently the bottom plate 5 under the measuring mechanism 4 is placed on the two reset components of the U-shaped frame 3 on the base table 2 (note that the upper end of the bolt 6 is retracted in the base table 2 at this time, and will not affect the movement of the measuring mechanism 4), because the measuring mechanism 4, the bottom plate 5 and the anti-dropping assembly have weight, so after the measuring mechanism 4 contacts the two reset components, the two reset components are pressed downward, so that the reset component changes from the original horizontal direction to the vertical direction, and at the same time that the reset component changes to the vertical direction, the two anti-dropping assemblies on both sides of the bottom plate 5 are extruded to the inside of the bottom plate 5, when the bottom plate 5 completely passes through the reset component, the reset component will remain vertical because of the blocking of the bottom plate 5 and the measuring mechanism 4, but the anti-dropping assembly on both sides of the bottom plate 5 will extend from the inside of the bottom plate 5 because of the lack of extrusion of the reset component, and then the measuring mechanism 4 is pushed, and the measuring mechanism 4 moves along the surface of the two reset components standing up towards the crossbar of the U-shaped frame 3 (the two reset components are installed at the vertical rod position of the U-shaped frame 3), when the measuring mechanism 4 cannot be pushed, it means that the measuring mechanism 4 has reached the specified position, at this time, the bolt 6 is rotated, and the screw rod of the bolt 6 rises and is screwed into the threaded hole at the bottom of the bottom plate 5, so that the quick connection between the measuring mechanism 4 and the base table 2 is realized, and because the three sides of the measuring mechanism 4 are blocked by the three sides of the U-shaped frame 3, even if only one bolt 6 is locked, the measuring mechanism 4 will not shake.

[0026] After the measurement is completed, only the connection between the bolt 6 and the bottom plate 5 needs to be loosened, and then the measuring mechanism 4 and the bottom plate 5 are pulled out by sliding towards the opening of the U-shaped frame 3, which is convenient and easy to operate.

[0027] As a preferred scheme of the utility model, the anti-dropping assembly comprises a pushing spring 7 and a trapezoidal block 8, spring cavities 501 are formed on both sides of the bottom plate 5, one end of the pushing spring 7 is fixedly connected with the inner wall of the spring cavity 501, the other end of the pushing spring 7 is fixedly connected with one end of the straight surface of the trapezoidal block 8, one end of the inclined surface of the trapezoidal block 8 abuts against the reset component, the outer wall of the trapezoidal block 8 is slidably connected with the inner wall of the spring cavity 501, and the side of the inclined surface of the trapezoidal block 8 facing downward is relatively narrow.

[0028] More specifically, when the bottom plate 5 descends along the surface of the reset assembly, at this time the inclined surface of the trapezoidal block 8 abuts against the surface of the reset assembly, and while the reset assembly is folded under the pressure of the bottom plate 5 and the measuring mechanism 4, the trapezoidal block 8 also compresses the pushing spring 7, so that the pushing spring 7 is gradually received in the spring cavity 501, and when the trapezoidal block 8 completely passes through the reset assembly, at this time the trapezoidal block 8 is pushed out by the pushing spring 7 due to the lack of the block of the reset assembly, so that the trapezoidal block 8 is inserted between the reset assembly and the base table 2 for limiting, thereby avoiding the measuring assembly from falling from directly above the base table 2.

[0029] As a preferred form of the present application, the reset assembly comprises a U-shaped block 9, a rotating shaft 11, a torsion spring 12 and two fixed blocks 10, one end of each of the two fixed blocks 10 is fixedly connected with the side wall of the U-shaped frame 3, both ends of the U-shaped block 9 are respectively sleeved and rotationally connected at both ends of the rotating shaft 11, the torsion spring 12 and the two fixed blocks 10 are both sleeved at the middle part of the rotating shaft 11, and the inner wall of each of the two fixed blocks 10 is fixedly connected with the outer wall of the rotating shaft 11, both ends of the torsion spring 12 are respectively fixedly connected with the U-shaped block 9 and the U-shaped frame 3.

[0030] More specifically, when the measuring mechanism 4 and the bottom plate 5 are pressed, the U-shaped block 9 is folded through the rotating shaft 11, thereby the U-shaped block 9 originally kept in a horizontal state under the action of the torsion spring 12 is pressed to stand up, and after the measuring mechanism 4 and the bottom plate 5 are completely inserted into the U-shaped frame 3, at this time the U-shaped block 9 is kept in a standing state, but there is still a certain height difference between the vertical U-shaped block 9 and the base table 2, and at this time the trapezoidal block 8 is just located in this height, and because the U-shaped block 9 is blocked by the bottom plate 5 and cannot reset, the measuring mechanism 4 and the bottom plate 5 that have been placed can be prevented from falling from directly above the base table 2.

[0031] As a preferred form of the present application, the middle part of the base table 2 is provided with a receiving opening 201, the bolt 6 is located in the receiving opening 201, one side of the receiving opening 201 is provided with a lifting cavity 202 in communication with the outside of the base table 2, the inner walls of the receiving opening 201 and the lifting cavity 202 are connected with an auxiliary limiting assembly, one end of the auxiliary limiting assembly is located outside the base table 2 and abuts against the bottom plate 5, and the other end of the auxiliary limiting assembly is connected with the bolt 6.

[0032] More specifically, by providing the receiving opening 201 and the lifting cavity 202, the auxiliary limiting assembly can be supported and received, and the movement direction of the auxiliary limiting assembly is limited.

[0034] More specifically, when the base table 2 and the bottom plate 5 are not connected, the upper end of the bolt 6 is located in the inside of the base table 2 (not protruding from the table top of the base table 2), and the push plate 14 connected on the bolt 6 is located in the storage opening 201.

[0035] When the bolt 6 is rotated to connect the base table 2 and the bottom plate 5, the bolt 6 is rotated with the push plate 14, the bolt 6 is gradually screwed into the inside of the bottom plate 5, and the push plate 14 is lifted along with the bolt 6, and the push plate 14 pushes the L-shaped plate 13 to be lifted, and then the other end of the L-shaped plate 13 away from the push plate 14 gradually protrudes from the opening of the lifting cavity 202, so as to abut against the displacement side of the bottom plate 5 away from the U-shaped frame 3, and then the U-shaped frame 3 limits the bottom plate 5, and further improves the stability.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
