Description

Technical Field

[0001] The utility model belongs to the technical field of perpendicularity detection, and particularly relates to a road and bridge vertical detector. Background Art

[0002] Among bridges, except for the abutments connecting the two ends with the embankment, the remaining intermediate support structures are called bridge piers. Bridge piers are the main supports of bridges, and the superstructure of the bridge is set on the bridge piers. After the construction of the bridge piers is completed, the perpendicularity of the pier columns needs to be detected, and the general deviation cannot be greater than 2 cm before the project acceptance can be carried out.

[0003] The existing road and bridge detection will use a special vertical detector for detection. For example, a road and bridge vertical detector disclosed in the publication number CN219244629U. During the use of the vertical detector in the above application, the applicant found that: in order to ensure that the plumb bob can extend out of the bridge to a suitable position, the whole device is relatively long in length, which is inconvenient for transportation and carrying. In order to solve the above problems, a road and bridge vertical detector is provided. Content of the Utility Model

[0005] The technical scheme adopted by the utility model is as follows: a road and bridge vertical detector, including a bottom plate, a vertical plate is fixedly connected to the bottom plate, an internal spline tube is rotatably connected to the vertical plate, a worm gear is fixedly connected to one side of the internal spline tube, a motor is fixedly installed on the vertical plate, the motor is connected with a worm through an output shaft, the worm is meshed with the worm gear, a cross plate is fixedly connected to the top of the vertical plate, a support plate is fixedly connected to the cross plate, a lead screw is rotatably connected to the support plate, one end of the lead screw is rotatably connected to a moving plate, a spline shaft is rotatably connected to the lower part of the moving plate, the spline shaft is adaptively and movably inserted into the internal spline tube, a wire reel is fixedly connected to one end of the spline shaft, a wire rope is wound on the wire reel, and the bottom end of the wire rope is tied to a plumb bob.

[0006] In a preferred embodiment, mounting holes are provided at the four corners of the bottom plate.

[0007] In a preferred embodiment, guide rods are fixedly connected to both sides of the upper part of the moving plate, and the guide rods are slidably connected to the support plate.

[0008] In a preferred embodiment, a limiting plate is fixedly connected to one end of the guide rod.

[0009] In a preferred embodiment, a support is fixedly connected to the bottom of the cross plate, and the internal spline tube is rotatably connected to the support.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0011] 1. In the present utility model, the moving plate is driven to move by the lead screw. Thus, when the entire vertical detector is not in use, the operator can rotate the lead screw to drive the spline shaft to retract into the internal spline tube by the moving plate, thereby realizing the contraction of the structure, reducing the volume of the entire vertical detector, and making it more convenient for storage and carrying. During use, the position of the wire reel extending out of the road bridge can be controlled by adjusting the extending length of the lead screw, which is convenient for adjustment and use, and avoids moving the entire device, thus having better practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0016] The following will be combined with Figure 1 - Figure 2 to provide a detailed description of a road bridge vertical detector according to an embodiment of the present utility model.

[0017] Embodiment:

[0018] A road bridge vertical detector provided by an embodiment of the present utility model is referred to Figure 1 and Figure 2As shown in the figure, it includes a bottom plate 1. A vertical plate 2 is fixedly connected to the bottom plate 1. An internal spline tube 3 is rotatably connected to the vertical plate 2. A worm gear 4 is fixedly connected to one side of the internal spline tube 3. A motor 5 is fixedly installed on the vertical plate 2. The motor 5 is connected to a worm 6 through an output shaft. The worm 6 meshes with the worm gear 4. A cross plate 7 is fixedly connected to the top of the vertical plate 2. A support plate 8 is fixedly connected to the cross plate 7. A lead screw 9 is rotatably connected to the support plate 8. One end of the lead screw 9 is rotatably connected to a moving plate 10. A spline shaft 11 is rotatably connected to the lower part of the moving plate 10. The spline shaft 11 is movably inserted into the internal spline tube 3 in a matching manner. One end of the spline shaft 11 is fixedly connected to a wire reel 12. A wire rope 13 is wound around the wire reel 12. The bottom end of the wire rope 13 is tied to a plumb bob 14. This structure fixes the bottom plate 1 on the top of a road bridge. Then, the operator rotates the lead screw 9 to drive the moving plate 10 to extend out of the bridge until it reaches a suitable position. At this time, the spline shaft 11 extends out of the internal spline tube 3. When it extends to a suitable position, the motor 5 can be started to drive the internal spline tube 3 to rotate. The internal spline tube 3 will drive the spline shaft 11 to rotate, and then drive the wire reel 12 to rotate, so as to release the wound wire rope 13, so that the plumb bob 14 falls to the designated position. Then, the operator can perform vertical detection on the road bridge;

[0019] When the above structure is not used in the later stage, the operator can rotate the lead screw 9 in the reverse direction, so that the moving plate 10 drives the spline shaft 11 to retract into the internal spline tube 3, so as to realize the contraction of the structure, reduce the volume of the entire vertical detector, and make it more convenient for storage and carrying.

[0020] Reference Figure 1 As shown in the figure, mounting holes 15 are provided at the four end corners of the bottom plate 1. This structure uses the mounting holes 15 to facilitate the operator to fix the bottom plate 1 on the top of the bridge pier through bolts, thereby ensuring the stable use of the entire vertical detector.

[0021] Reference Figure 1 and Figure 2 As shown in the figure, guide rods 16 are fixedly connected to both sides of the upper part of the moving plate 10. The guide rods 16 are slidably connected to the support plate 8. This structure uses the guide rods 16 to guide the movement of the moving plate 10.

[0022] Reference Figure 1 As shown in the figure, a limit plate 18 is fixedly connected to one end of the guide rod 16. This structure uses the positioning plate 18 to limit the maximum outward extension position of the moving plate 10.

[0023] Reference Figure 2 As shown in the figure, a support 17 is fixedly connected to the bottom of the cross plate 7. The internal spline tube 3 is rotatably connected to the support 17. This structure uses the support 17 to assist in supporting the internal spline tube 3, thereby ensuring the stability of the rotation of the internal spline tube 3 in the later stage.

[0024] It should be noted that: the vertical detector disclosed in the above embodiment is applied to the detection of road bridges.

[0025] The implementation principle of a vertical detector for road bridges in an embodiment of this application is as follows: When in use, the user fixes the bottom plate 1 on the top of the road bridge, and then rotates the lead screw 9 to drive the moving plate 10 to extend out of the bridge until it reaches a suitable position. At this time, the spline shaft 11 extends out of the internal spline tube 3. When it extends to a suitable position, the motor 5 can be started to drive the internal spline tube 3 to rotate. The internal spline tube 3 will drive the spline shaft 11 to rotate, and then drive the wire reel 12 to rotate, thereby releasing the wound wire rope 13, so that the plumb bob 14 falls to the designated position. Then, the user can perform a vertical inspection on the road bridge. After the inspection is completed, the user can rotate the lead screw 9 in the reverse direction, so that the moving plate 10 drives the spline shaft 11 to retract into the internal spline tube 3, thereby realizing the contraction of the structure, reducing the volume of the entire vertical detector, and making it more convenient for storage and carrying.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
