Description

Technical Field

[0001] The present invention relates to the field of bridge management engineering, and particularly to a clamping portable bridge appearance detection device. Background Art

[0002] With the rapid economic development of our country, our country has become a major bridge country in the world, and the number of small and medium-span bridges in our country accounts for a relatively high proportion in the total number of bridges. During the service period of bridge structures, they are constantly affected by environmental erosion, static and dynamic load effects, material fatigue damage and erosion deterioration, etc., often accompanied by the occurrence of appearance diseases and structural damages. For long-span and high-importance bridges, there are usually special maintenance management units for daily maintenance. However, due to a series of reasons such as wide distribution, large quantity, and complex hydrological conditions of small and medium-span bridges, the maintenance management work is relatively difficult. In addition, due to factors such as the long construction history and unclear management subject of some small and medium-span bridges, this has greatly shortened the normal service life of small and medium-span bridges and left serious safety hazards.

[0003] Our country has clearly stipulated that regular inspections, periodic inspections and special monitoring should be carried out for urban bridges. Among them, the regular and periodic inspections require engineering and technical personnel to be equipped with cameras, crack observation instruments and auxiliary exploration tools to go to the bridge site to observe and record the appearance disease conditions and damage reasons of the bridges on the spot, and to evaluate and grade the technical conditions of the bridges. The traditional appearance detection method requires engineering and technical personnel to drive an inflatable boat to visually observe the upper and lower structures of small and medium-span bridges through the bottom of the bridge span. For complex river hydrological conditions, ladders or scaffolds are also used for detection, which undoubtedly increases the technical threshold and detection cost of the appearance detection of small and medium-span bridges, and also reduces the detection efficiency of engineering and technical personnel. Therefore, it is necessary to develop a handheld portable bridge appearance detection device, which can improve the detection efficiency of engineering and technical personnel for small and medium-span bridges while meeting the technical requirements of appearance detection, and truly realize the high-quality and comprehensive development of our country as a major bridge country. Summary of the Invention

[0004] In view of the deficiencies in the background art, the technical problem to be solved by the present invention is to provide a clamping portable bridge appearance detection device, which not only improves the efficiency of bridge detection, but also is convenient to carry, reduces the detection difficulty, and meets the needs of investigation under complex field environmental conditions.

[0005] The present invention is achieved by adopting the following technical solutions: A clamping portable bridge appearance detection device, including a handle device, a connection component, and a detection component. The detection component includes a camera device and a monitoring device. The handle device is connected to the camera device through the connection component, and the monitoring device is installed at the front end of the connection component. The connection component is composed of multiple universal rotary brackets and telescopic rod members. The multiple telescopic rod members are sequentially connected through a universal rotary connection component. The universal rotary bracket includes a bracket seat, two powerful clamps, and a bracket adjustment part. The two powerful clamps are symmetrically arranged on both sides of the bracket seat in a rotatable manner, and adjacent telescopic rod members are respectively connected to the powerful clamps on both sides.

[0006] Furthermore, the powerful clamp is composed of a clamp component and a rotary ball head. The clamp component and the rotary ball head are fixedly connected through a connecting rod. A damping cushion layer is arranged on the outer side of the rotary ball head. The bracket seat is composed of an upper support and a lower support. The rotary ball heads of the powerful clamps on both sides are respectively symmetrically clamped between the upper support and the lower support. The distance between the upper support and the lower support is adjusted through the bracket adjustment part, so that the rotary ball head of the powerful clamp can achieve a 720° rotation function between the upper support and the lower support.

[0007] Furthermore, the bracket adjustment part includes a bracket screw and a bracket knob. The bottom end of the bracket screw is fixed on the lower support, the upper end of the bracket screw passes through the upper support and extends above the upper support, and the bracket knob is threadedly connected to the screw and can move up and down along the bracket screw, thereby adjusting the distance between the upper support and the lower support.

[0008] Furthermore, the clamp component is composed of an upper clamp part and a lower clamp part. A clamp screw is arranged between the upper clamp part and the lower clamp part. The clamp knob is threadedly connected to the clamp screw. By rotating the clamp knob, the upper clamp part or the lower clamp part moves along the clamp adjustment screw, adjusting the distance between the upper clamp part and the lower clamp part, thereby controlling the size of the clamp opening. Anti-slip cushion layers are arranged at the clamp opening positions of the upper clamp part and the lower clamp part.

[0009] Furthermore, the camera device includes a camera base and a spherical camera. The camera base is installed at the end part of the connection component, and the spherical camera is rotatably connected to the camera base. The spherical camera is wirelessly connected to the monitoring device, and the monitoring device controls the spherical camera to rotate freely horizontally.

[0010] Furthermore, the monitoring device includes a multi-functional electronic notebook and a notebook bracket. The notebook bracket is installed at the front end part of the connection component through a connecting rod, and the multi-functional electronic notebook is detachably installed on the notebook bracket. Operation buttons and an electronic detection screen are arranged on the multi-functional electronic notebook. The operation buttons remotely control the angle adjustment of the spherical camera on the camera base, and the electronic detection screen collects and displays the photo data transmitted by the spherical camera.

[0011] Further, the telescopic rod member is composed of three telescopic section rods with a hollow structure. The inner diameters of the three telescopic section rods increase in sequence and are sleeved with each other. A telescopic control knob is arranged at the connection of adjacent telescopic section rods. By sliding the adjacent telescopic section rods in a sleeved manner, the length of the overall telescopic rod member is controlled, and it is fastened by the telescopic control knob.

[0012] Further, the handle device includes a clamping handle, a clamping screw rod and a clamping knob. One end of the clamping screw rod is fixed to the upper clamping handle, and the other end of the clamping screw rod passes through and extends out of the lower clamping handle. The outer end of the clamping screw rod is threadedly connected to the clamping knob, and the distance between the upper clamping handle and the lower clamping handle is controlled by the knob.

[0013] The telescopic section rod is made of hollow, high-strength and lightweight carbon fiber material.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The camera device is installed at the end of the connection component, and the connection component is spliced by a universal rotating bracket and a telescopic rod member. According to the different sizes of the cross-bridge structure, the length of the connection component is adjusted, and at the same time, according to the characteristics of different cross-bridge structures, the angle between adjacent telescopic rod members is adjusted to achieve any form to meet the detection needs of the bottom and lower structures of the beam of small and medium-span bridge structures in complex environments. Engineering technicians only need to stand on the relatively safe bridge deck without climbing the detection bracket and driving an inflatable boat on the water for observation, thus liberating the hands of engineering technicians and ensuring personal safety.

[0016] 2. The spherical camera connected by wireless Bluetooth is controlled by a multi-functional electronic field book to freely rotate horizontally, and can detect the diseases of the bottom and lower structures of the beam of small and medium-span bridge structures from multiple angles, over long distances and in all directions. Engineering technicians collect and record problems and diseases such as beam bottom cracking, hinge joint water seepage, and support inclination through the photo data information displayed on the electronic detection screen, thereby improving the efficiency of bridge detection.

[0017] 3. The detachable and assembled function can realize the convenient carrying of the device and meet the needs of investigation under complex field environmental conditions.

[0018] 4. The standard telescopic section rod end is made of hollow, high-strength and lightweight carbon fiber material, and its strength is more than ten times that of plastic products. It has the characteristics of corrosion resistance, anti-aging and long service life. In harsh environments, such as rainy or humid environments, it can still ensure that the bridge appearance detection device functions normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and their effects of the present invention as follows.

[0027] Referring to Figures 1-5 As shown, the first embodiment of the present invention provides a clamping portable bridge appearance detection device, including a handle device 1, a connection component, and a detection component. The detection component includes a camera device 2 and a monitoring device 3. The handle device 1 is connected to the camera device 2 through the connection component, and the monitoring device 3 is installed at the front end of the connection component or at the handle device.

[0028] The connection component is composed of a plurality of universal rotating brackets 4 and telescopic rod members 5. Adjacent telescopic rod members 5 are installed and connected through the universal rotating brackets 4. The universal rotating bracket 4 includes a bracket seat 6, two powerful clamps 7, and a bracket adjusting part 8. The two powerful clamps are symmetrically and rotatably arranged on both sides of the bracket seat 6, and the bracket seat 6 is adjusted through the bracket adjusting part 8 to realize the 720° rotation function of the two powerful clamps on the bracket seat 6.

[0029] The large pliers 7 are composed of a plier component 71 and a rotating ball head 72, and the plier component 71 and the rotating ball head 72 are fixedly connected by a connecting rod 73. The bracket base 6 is composed of an upper bracket 61 and a lower bracket 62. The rotating ball heads 72 of the two large pliers on both sides are symmetrically clamped between the upper bracket 61 and the lower bracket 62. The distance between the upper bracket 61 and the lower bracket 62 is adjusted by a bracket adjusting part 8, so that the rotating ball head of the large pliers can realize a 720° rotation function between the upper bracket and the lower bracket. A damping cushion layer 721 is arranged on the outer side of the rotating ball head to increase the friction force between the rotating ball head and the universal rotating bracket and meet the requirements of different splicing forms of this device for the universal rotating bracket.

[0030] The bracket adjusting part 8 includes a bracket screw 81 and a bracket knob 82. The bottom end of the bracket screw 81 is fixed on the lower bracket 62, the upper end of the bracket screw 81 passes through the upper bracket 61 and extends above the upper bracket 61, and the bracket knob 82 is threadedly connected to the bracket screw 81 and can move up and down along the bracket screw 81, so as to adjust the distance between the upper bracket 61 and the lower bracket 62.

[0031] The plier component 71 is composed of an upper plier part 711 and a lower plier part 712. A plier screw 713 is arranged between the upper plier part 711 and the lower plier part 712.

The telescopic section rods 51 are made of hollow high-strength and lightweight carbon fiber materials. The inner diameters of the three telescopic section rods increase in sequence and are sleeved with each other. A telescopic control knob 52 is arranged at the connection of adjacent telescopic section rods. By sliding and sleeving between adjacent telescopic section rods 51, the length of the overall telescopic rod member is controlled. When it slides to the required position, it is fixed by the telescopic control knob 52, and thus the telescopic distance of the telescopic section rod can be realized. After the length of the telescopic rod member is adjusted, the head and tail section telescopic section rods 51 are respectively installed and fixed on the plier component of the universal rotating bracket to complete the installation of the connection component.

[0033] The camera device 2 includes a camera base 21 and a spherical camera 22. The camera base 21 is installed at the end of the connection component.

The other end of the clamping screw 12 passes through and extends out of the lower clamping handle. The outer end of the clamping screw 12 is threadedly connected to the clamping knob 13. The distance between the upper clamping handle and the lower clamping handle is controlled by the knob 13 so that it can be installed and fixed on the bridge railing handrail.

[0036] Among them, the materials of non-specified components such as the notebook bracket 32, the universal rotating bracket 4, the rotating ball head 72, the strong clamp 71, the clamping screw 12, and the clamping knob 13 are all stainless steel materials to prevent the influence of component rust on this detection device.

[0037] The usage steps of the above-mentioned clamping portable bridge appearance detection device when conducting the appearance detection of small and medium-span bridges are as follows:

[0038] 1) Adjust the length of the standard telescopic section rod 51 through the telescopic control knob 52, and then splice the handle device 1, the telescopic member 5, and the camera base 21 through the universal rotating bracket 4.

[0039] 2) The clamping handle 11 can be fixed on the guardrail handrail or railing of the small and medium-span bridge to be detected, and the detection angle of the telescopic member 5 is adjusted through the bracket adjustment part 8 and the rotating ball head 72, so as to meet the morphological requirements for the appearance detection of small and medium-span bridges in complex environments.

[0040] 3) Mount the tablet computer bracket 32 on the clamping handle 11, mount the spherical camera 22 on the camera base 21, and the multifunctional electronic tablet computer 31 can be snap-fixed on the tablet computer bracket 32. The engineering technicians clamp this detection device on the guardrail and railing of the bridge.

[0041] 4) Stand on the bridge deck of a small or medium-sized bridge and control the detection direction and angle of the spherical camera 22 by operating the buttons of the multifunctional electronic tablet computer 31. The spherical camera 22 transmits the information observed at the bottom of the bridge to the electronic detection screen 312 of the multifunctional electronic tablet computer through wireless Bluetooth technology. The engineering technicians observe whether there are cracks at the bottom of the bridge girder, whether there is water seepage in the hinge joint, whether the bearing is tilted, and other problems and diseases according to the pictures captured by the camera, and record and store relevant photos.

[0042] 5) After the apparent inspection of the small and medium-span bridge is completed, disassemble the multifunctional electronic tablet computer 31, the tablet computer bracket 32, and the camera base 21 from the portable bridge apparent inspection device step by step through the operation steps of "erecting and disassembling in reverse". Then loosen the bracket knob 82 and the telescopic control knob 52 to separate and reset the universal rotary bracket 4 and the telescopic section rod 51, so as to realize the convenient carrying of the bridge apparent inspection device.

[0043] Refer to Figure 6 As shown in the figure, the second embodiment of the present invention provides a clamping portable bridge apparent inspection device, which is basically the same as the first embodiment, except that: the handle device 1 includes a clamping part 14 and a handle 15. One end of the handle is connected to the connecting component through the universal rotary bracket 4, and the handle is rotatably connected to the clamping part 14 through a rotating shaft 16. The clamping part is arranged in an n shape, and a plurality of universal wheel components 17 are evenly distributed on the inner wall of the clamping part. A fastening device 18 is provided at the lower opening of the clamping part, and the clamping part is installed on the bridge railing through the fastening device. When performing the apparent inspection of a small and medium-span bridge, sleeved the clamping part on the bridge railing handrail, and adjust the size of the lower opening of the clamping part 14 through the fastening device 18 to fix it on the bridge railing handrail. The outside of the universal wheel 17 is wrapped with an anti-slip cushion layer to increase the friction force and prevent the clamping part from moving when in a fastened state. The engineering technicians can change the orientation of the connecting component by rotating the handle 15 to monitor different parts of the bottom of the beam, expand the monitoring range, and reduce the workload. When it is necessary to move the position, just loosen the fastening device, and the clamping part can move along the bridge handrail with the assistance of the universal wheel component, easily realizing the movement of the monitoring position, improving the efficiency of bridge monitoring, and reducing the workload of the engineering technicians.

[0044] A rotating shaft seat 19 is provided at the top of the clamping portion 14.

After the handle rotates to a specified position along the rotating shaft seat 19, the rotating shaft fastening cover 20 is tightened, and the handle is in a fixed and non-rotatable state. When the orientation of the handle needs to be adjusted, only the rotating shaft fastening cover needs to be loosened, and the handle can be rotated.

[0045] The fastening device 18 includes a fastening screw 181 and two adjusting nuts 182. Through holes 141 are symmetrically provided at the lower ends of the two side walls of the clamping portion 14. The fastening screw 181 passes through the through holes 141 on both sides in sequence, and the two adjusting nuts 182 are respectively threadedly connected to both sides of the fastening screw 181. By rotating the two adjusting nuts 182 on both sides, the clamping portion is clamped and fixed on the bridge railing handrail.

[0046] Referring to Figure 7 As shown, the third embodiment of the present invention provides a clamping portable bridge appearance detection device, which is basically the same as the second embodiment, only the structure of the fastening device is different. The difference lies in that: two symmetrically distributed threaded holes 141 are provided at the lower openings of the two side walls of the clamping portion, and each threaded through hole is provided with a fastening device 18. The fastening device 18 includes an adjusting screw 183, and fixed ends are provided at both ends of the adjusting screw. The adjusting screw is threadedly connected to the threaded hole. One side fixed end 184 is arranged inside the clamping portion, and the other side fixed end 185 is located at the outer end of the clamping portion. An anti-slip pad 186 is provided on the inner side fixed end 184. When installing the clamping portion, the clamping portion is sleeved on the bridge railing handrail, and at the same time, the outer side fixed ends 185 of the two adjusting screws are rotated, so that the two adjusting screws 183 move along the threaded holes until the inner side fixed ends of the two adjusting screws respectively abut against the bridge handrail, and the installation of the clamping portion is completed.

[0047] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention.
