Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier detection, in particular to a verticality detection device for bridge piers. Background Art

[0002] In recent years, my country's transportation industry has developed rapidly, and the number of expressways has increased. In order to ensure the safety and comfort of vehicle driving, the construction of bridge piers has become an important part of the project during the construction of expressway projects.

[0003] Bridge piers are the main load-bearing components of highways. During the driving process of vehicles, there is load pressure on the superstructure of the bridge, and the bridge piers mainly transmit this pressure to the foundation. After the highway is put into use, the bridge piers will be subjected to greater wind force, water pressure and wave force, and they need to resist the impact of ships. Therefore, the construction of bridge piers has a great impact on the overall quality of the highway. Therefore, the quality of construction is to ensure the safe and stable operation of the highway. The verticality of bridge piers has become an important indicator of bridge safety.

[0004] In the prior art, when monitoring the verticality of bridge piers, the plumb line method and the total station horizontal distance method are mostly used. The plumb line method has very high requirements on the environment, and the measurement results are greatly affected by wind. The total station horizontal distance method needs to set up the instrument multiple times to measure a pier, and the work efficiency is low. Therefore, three-dimensional scanning technology has appeared on the market to monitor the verticality of bridge piers. Generally, the pier point cloud is obtained through three-dimensional scanning, and then the pier is manually de-noised, the pier is manually extracted, and then the verticality of the pier is obtained by fitting. However, the existing three-dimensional scanning technology usually requires carrying a scanner to the site to obtain data for the verticality monitoring of bridge piers. The construction site environment is relatively complex. It is very easy to cause falls and damage when the scanner is working. Therefore, a verticality detection device for bridge piers that is not easy to cause falls and damage is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a verticality detection device for bridge piers that is not easy to cause damage due to falls.

[0006] The utility model provides the following technical solution: a verticality detection device for a bridge pier, comprising a support mechanism, a scanning mechanism arranged on the support mechanism, a weight-increasing mechanism arranged in the middle of the support mechanism, and a limiting mechanism arranged on the weight-increasing mechanism;

[0007] The weight-increasing mechanism comprises a bracket arranged on the supporting mechanism, a vertical rod arranged at the lower end of the bracket, a support block arranged at the lower end of the vertical rod, a plurality of counterweights are stacked on the support block, and the counterweights are coaxial with the vertical rod and the support block;

[0008] The limiting mechanism includes a threaded seat and an external thread arranged on the outer wall of the vertical rod, and the threaded seat is threadedly connected to the external thread.

[0009] Furthermore, protrusions are provided on both sides of the threaded seat, and the protrusions are integrally formed with the threaded seat.

[0010] Furthermore, the counterweight component includes a counterweight block, a positioning block arranged on the counterweight block, and an opening opened along the middle of the positioning block toward the outside, and the vertical rod is located at the opening.

[0011] Furthermore, the support mechanism includes a mounting seat, a plurality of support components evenly spaced around the outer wall of the mounting seat, the support components including a connecting seat fixedly connected to the mounting seat, a fixing member fixedly connected to the connecting seat, a rotating rod rotatably connected to the connecting seat, a support foot arranged at the lower end of the rotating rod, a through hole opened in the middle of the support foot, and a plurality of connecting columns evenly spaced at the through hole.

[0012] Furthermore, the scanning mechanism includes a sliding rod slidably connected to the mounting seat, a pan-tilt platform arranged on the sliding rod, and a three-dimensional laser scanner arranged on the pan-tilt platform.

[0013] Furthermore, the verticality detection device also includes a plurality of anti-skid mechanisms arranged on the support foot, and the anti-skid mechanisms include a conical member slidably connected to the support foot and a spring arranged between the support foot and the conical member.

[0014] Furthermore, the verticality detection device also includes a plurality of pushing mechanisms, which include a support arranged on the support foot, a plurality of slide rails arranged on the support foot, a pushing frame slidably connected to the slide rail, a contact block is arranged on the upper part of the conical member, the pushing frame is located below the contact block, a screw is rotatably connected to the support, and the screw is threadedly connected to the pushing frame.

[0015] The beneficial effects of the utility model are as follows: the gravity at the center of the verticality detection device can be increased by the action of the counterweight, and when the wind speed at the construction site is high, the verticality detection device will not be blown down and damaged. Furthermore, the opening of the second counterweight corresponds to the protrusion of the first counterweight, which can effectively prevent the stacked counterweights from moving, and at the same time, the effect of uniform weight distribution can be achieved. The through hole can facilitate the passage of airflow, further preventing strong winds from blowing onto the verticality detection device. The threaded seat is rotated by the protrusion, and the threaded seat is moved toward the direction of the counterweight by the action of the external thread. Finally, the threaded seat contacts the uppermost counterweight and presses it, thereby further preventing the counterweight from moving and falling. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] A verticality detection device for bridge piers, please refer to Figures 1 to 6 , shown is a first embodiment of the utility model, comprising a support mechanism 1, a scanning mechanism 2 arranged on the support mechanism 1, a weight-increasing mechanism 3 arranged in the middle of the support mechanism 1, and a limiting mechanism 4 arranged on the weight-increasing mechanism 3;

[0030] Specifically, the support mechanism 1 includes a mounting seat 11, three support assemblies 12 evenly spaced around the outer wall of the mounting seat 11, and more support assemblies 12 may be provided according to actual conditions in other embodiments. In this embodiment, three support assemblies 12 are provided to achieve better stability while saving costs. The support assembly 12 includes a connecting seat 121 fixedly connected to the mounting seat 11, a fixing member 122 fixedly connected to the connecting seat 121, a rotating rod 123 rotatably connected to the connecting seat 121, a supporting foot 126 provided at the lower end of the rotating rod 123, a through hole 124 opened in the middle of the supporting foot 126, and a plurality of connecting columns 125 evenly spaced at the through hole 124;

[0031] The scanning mechanism 2 includes a slide bar 21 slidably connected to the mounting seat 11, a pan platform 22 arranged on the slide bar 21, and a three-dimensional laser scanner 23 arranged on the pan platform 22;

[0032] The weight-increasing mechanism 3 includes a bracket 31 arranged on the supporting mechanism 1, a vertical rod 32 arranged at the lower end of the bracket 31, a support block 33 arranged at the lower end of the vertical rod 32, a plurality of counterweights 34 are stacked on the support block 33, the counterweights 34 are coaxial with the vertical rod 32 and the support block 33, the counterweights 34 include a counterweight block 341, a positioning block 342 arranged on the counterweight block 341, and an opening 343 opened from the middle of the positioning block 342 to the outside, and the vertical rod 32 is located at the opening 343;

[0033] The limiting mechanism 4 includes a threaded seat 42, an external thread 41 provided on the outer wall of the vertical rod 32, the threaded seat 42 is threadedly connected to the external thread 41, and protrusions 43 are provided on both sides of the threaded seat 42. The protrusions 43 are integrally formed with the threaded seat 42.

[0034] When the operator needs to use the verticality detection device, the operator first unfolds the rotating rod 123 to make the rotating rod 123 contact with the fixing member 122, and then sets up the verticality detection device. The through hole 124 facilitates airflow to prevent strong wind from blowing into the verticality detection device. The sliding rod 21 is slidably connected to the mounting seat 11 to adjust the height of the three-dimensional laser scanner 23. The pan-tilt head 22 can adjust the left and right up and down swing angles of the three-dimensional laser scanner 23. After setting up the verticality detection device, the operator can put the counterweight 34 on the support block 33 to make the counterweight 34 The opening 343 is placed on the vertical rod 32, and the counterweight 34 and the vertical rod 32 are located at the same axis. After placing the first counterweight 34, other counterweights 34 can be placed in sequence. Specifically, after placing the first counterweight 34, the operator takes out the second counterweight 34 so that the opening 343 of the second counterweight 34 corresponds to the protrusion 43 of the first counterweight 34 and then places it. Similarly, several counterweights 34 are placed according to specific usage scenarios. Through the correspondence between the protrusion 43 and the opening 343, the stacked counterweights 34 can be effectively prevented from moving, and the effect of uniform weight distribution can also be achieved. The gravity at the center of the verticality detection device can be increased by the action of the counterweight 34. When the wind speed at the construction site is high, the verticality detection device will not be blown down. After the counterweight 34 is placed, the operator can rotate the threaded seat 42 through the protrusion 43, and the threaded seat 42 moves toward the counterweight 34 through the action of the external thread 41. Finally, the threaded seat 42 contacts the uppermost counterweight 34 and presses it tightly, thereby further preventing the counterweight 34 from moving and falling. After the threaded seat 42 presses the counterweight 34 tightly, the operator can start the three-dimensional laser scanner 23 to scan the bridge pier. During the scanning, the operator can operate the pan-tilt head 22 and the slide bar 21 to move the 3D laser scanner 23 up and down, and swing it up, down, left and right to obtain the 3D information of the bridge pier in all directions. After obtaining the 3D information of the bridge pier, when the operator needs to put away the verticality detection device, he first rotates the threaded seat 42 through the protrusion 43 so that the threaded seat 42 is no longer in contact with the counterweight 34, and then removes the counterweight 34 in turn. After the counterweight 34 is removed, the rotating rod 123 is put away so that it is no longer in contact with the fixing part 122, and then the verticality monitoring device is moved away and put away.

[0035] To summarize, the gravity at the center of the verticality detection device can be increased through the action of the counterweight 34. When the wind speed at the construction site is high, the verticality detection device will not be blown down and damaged. Furthermore, the opening 343 of the second counterweight 34 corresponds to the protrusion 43 of the first counterweight 34, which can effectively prevent the stacked counterweights 34 from moving, and at the same time, the effect of uniform weight distribution can be achieved. The through hole 124 can facilitate the passage of air flow, further preventing strong winds from blowing into the verticality detection device. The threaded seat 42 is rotated by the protrusion 43, and the threaded seat 42 is moved toward the direction of the counterweight 34 through the action of the external thread 41. Finally, the threaded seat 42 contacts the uppermost counterweight 34 and presses it tightly, thereby further preventing the counterweight 34 from moving and falling.

[0036] Please refer to Figures 7 and 8 , shown is a second embodiment of the utility model. The difference between this embodiment and the first embodiment is that: on the basis of the first embodiment, it also includes a plurality of anti-slip mechanisms 5 and a plurality of pushing mechanisms 6 arranged on the supporting foot 126.

[0037] Among them, nine anti-slip mechanisms 5 are arranged on each support leg 126, and in other embodiments, they can also be arranged according to specific actual conditions. The number of the pushing mechanisms 6 arranged is three corresponding to the support legs 126;

[0038] The anti-slip mechanism 5 includes a conical member 51 slidably connected to the support foot 126 and a spring 52 disposed between the support foot 126 and the conical member 51 .

[0039] The pushing mechanism 6 includes a support 62 arranged on the support foot 126, a plurality of slide rails 61 arranged on the support foot 126, a pushing frame 63 is slidably connected to the slide rail 61, a contact block 64 is arranged on the upper part of the conical member 51, the pushing frame 63 is located below the contact block 64, a screw rod 65 is rotatably connected to the support 62, and the screw rod 65 is threadedly connected to the pushing frame 63.

[0040] When the operator unfolds the rotating rod 123, the rotating rod 123 will also drive the supporting foot 126 to unfold. When the operator sets up the verticality detection device, the supporting foot 126 contacts the ground, the anti-skid mechanism 5 also contacts the ground, and the conical member 51 of the anti-skid mechanism 5 contacts the ground. The spring 52 gives the conical member 51 a downward force to make it closely contact with the ground. Therefore, through the action of the conical member 51, the ground gripping effect can be achieved reliably to prevent the verticality detection device from being blown by the wind. When the operator needs to retract the verticality detection device, if the conical member 51 is exposed, it is easy to cause an unsafe factor. At this time, the operator can rotate the screw 65, and the screw 65 drives the pushing frame 63 to move upward, and the pushing frame 63 moves upward to contact the contact block 64, thereby pushing the contact block 64 to move upward, and the upward movement of the contact block 64 drives the conical member 51 to move upward, thereby causing the conical member 51 to retract into the inner side of the supporting foot 126 to prevent it from leaking out and causing an unsafe factor.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
