Description

Technical Field

[0001] The present invention relates to the technical field of bridge bottom beam inspection vehicle track installation equipment, in particular to a bridge bottom beam inspection vehicle track and accessory installation tool. Background Art

[0002] The bridge beam bottom inspection vehicle is a type of bridge maintenance and repair equipment that can move at the bottom of the bridge. It is mainly composed of a truss platform, a drive component, and an electronic control device. The whole vehicle relies on the drive component to hang on the beam bottom track to achieve free movement at the bottom of the bridge. However, some bridges are cross-river and cross-sea bridges. There is a problem that it is very difficult to arrange the bridge inspection vehicle track after the beam is erected. The traditional inspection vehicle track installation method is mainly to arrange the track for the beam section in advance in the beam yard before the beam is erected, and then transport it to the bridge site for erection together with the beam section. This installation method has high requirements for installation conditions and installation time. The construction site often changes a lot, and it is difficult to control the track installation time of each beam section. Once the track installation time in the beam yard is missed, the traditional installation method will not be able to meet the track installation operations in the river and sea environment.

[0003] The main issues are as follows:

[0004] The traditional installation method is completely dependent on the progress of beam production in terms of construction progress. It requires personnel to be stationed at the beam site for a long time to communicate and coordinate with the beam production unit, resulting in increased labor costs and loss of control over the construction schedule.

[0005] If the beam fabrication progress is slower than the track installation progress, it will cause on-site construction workers to miss work and delay the construction period;

[0006] If the beams are manufactured too quickly, the track installation progress will not be able to keep up with the speed of beam manufacturing, which will result in the track having to be installed offshore after the beams are erected. Traditional installation methods will not be able to achieve track installation operations.

[0007] In summary, the traditional inspection vehicle track installation method has high requirements for the control of installation time nodes, the timeliness of installation personnel and materials, and a significant impact on the installation progress of the inspection vehicle track when the beam production speed is too fast or too slow. In addition, installation operations in river and sea environments cannot be achieved. Therefore, the traditional installation method has problems such as uncertainty in construction planning, high manpower and time costs, and a single installation environment. Summary of the Invention

[0008] The present invention aims to provide a bridge beam bottom inspection vehicle track and accessory installation tooling to solve the problem that the existing technology of arranging the track for the beam section in advance in the beam yard before erecting the beam and then transporting it to the bridge site for installation is affected by the progress of the beam and cannot realize installation operations in river and sea environments.

DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] Example 1

[0045] like Figures 1-9As shown, this embodiment proposes a bridge beam bottom inspection vehicle track and accessory installation tool, including an upper truss 1, and a first walking mechanism 2 is installed at the bottom of the upper truss 1. The first walking mechanism 2 is used to walk on the bridge deck and contact the bridge deck. Specifically, the first traveling mechanism 2 includes a first drive wheel 22, a first guide wheel 23, and a first hydraulic support leg 24 mounted on a first traveling chassis 21. The first traveling chassis 21 is fixedly connected to the upper truss 1. The first drive wheel 22 directly contacts the bridge deck to enable the traveling function of the first traveling mechanism 2. The first guide wheel 23 is mounted on the outside of the first traveling chassis 21 and contacts the curb of the beam to enable the guiding function of the first traveling mechanism 2, ensuring that the first traveling mechanism 2 moves along the designed path on the bridge deck. The first hydraulic support leg 24 is capable of upward and downward extension. When the first hydraulic support leg 24 is retracted, the first drive wheel 22 directly contacts the bridge deck, allowing the first traveling mechanism 2 to travel normally. When the first hydraulic support leg 24 is extended, it contacts the bridge deck to enable temporary parking and prevent accidents caused by the vehicle slipping. The first drive wheel 22 and the first guide wheel 23 are provided with a rubber coating.

[0046] A track hoisting frame 3 is mounted on the top of the upper truss 1. The top of the track hoisting frame 3 extends out of the side of the upper truss 1. A track hoisting device 4 is mounted on the track hoisting frame 3. The track hoisting device 4 is located outside the upper truss 1 and is used to lift the bridge inspection vehicle track and accessories. In this embodiment, the track hoisting device 4 can be an electric hoist. The track hoisting frame 3 is equipped with an electric hoist track 16 to facilitate the movement of the electric hoist on the track hoisting frame 3 and to facilitate lifting from different positions.

[0047] One end of the upper truss 1 extends out of the bridge deck, and an upper and lower channel 5 is connected to the bottom thereof. The upper and lower channel 5 is a vertical channel, which is arranged perpendicular to the upper truss 1 and extends to the bottom of the bridge deck.

[0048] A lower working platform 6 is rotatably connected to the bottom of the vertical passage 5. The lower working platform 6 is horizontally arranged and internally provided with a track on which a platform trolley is mounted. Specifically, a slewing mechanism 7 is connected to the bottom of the vertical passage 5. The lower working platform 6 is connected to the slewing mechanism 7, and the lower working platform 6 is able to rotate horizontally around the connection point. Therefore, the lower working platform 6 can rotate to pass through the pier in the same direction as the bridge when passing through the pier. In this embodiment, the slewing mechanism 7 can be a slewing bearing.

[0049] The tooling also includes an intermediate lifting device 8, at the bottom of which is mounted a second traveling mechanism 9, which is used to travel on the bridge deck and contact the bridge deck. Specifically, the second traveling mechanism 9 includes a second driving wheel 92, a second guide wheel 93, and a second hydraulic support leg mounted on a second traveling chassis 91. The second traveling chassis 91 is fixedly connected to the intermediate lifting device 8. The second driving wheel 92 directly contacts the bridge deck to enable the second traveling mechanism 9 to travel. The second guide wheel 93 is mounted on the inner side of the second traveling chassis 91. The second guide wheel 93 contacts the curb of the beam body to enable the second traveling mechanism 9 to guide and ensure that the second traveling mechanism 9 moves along the designed path on the bridge deck. The second hydraulic support leg can be extended and retracted. When the second hydraulic support leg is retracted, the second driving wheel 92 directly contacts the bridge deck, allowing the second traveling mechanism 9 to travel normally. When the second hydraulic support leg is extended, it can contact the bridge deck to achieve temporary parking.

[0050] The bottom of the intermediate lifting device 8 is connected to an intermediate platform 10. The intermediate platform 10 is horizontally arranged and along the transverse direction of the bridge. The intermediate platform 10 is connected to the intermediate lifting device 8 through a vertical connecting rod 11. The vertical connecting rod 11 passes through the beam gap, and the beam gap is along the longitudinal direction of the bridge. The vertical connecting rod 11 and the intermediate platform 10 are also connected with a diagonal brace 12. The intermediate platform 10 can be vertically lifted and lowered under the action of the intermediate lifting device 8. After the intermediate platform 10 is lifted to a level higher than the bridge pier, it can smoothly pass over the bridge pier. When the lower working platform 6 is rotated to the transverse direction of the bridge, the intermediate platform 10 is connected to the lower working platform 6 through a pin shaft. When encountering a bridge pier, the two are disconnected, the lower working platform 6 is rotated, the intermediate platform 10 is lifted, and the two are connected again after passing the bridge pier.

[0051] Since one end of the upper truss 1 extends out of the bridge deck and is connected to the upper and lower channels 5, the lower working platform 6 and other components in sequence, one end of the upper truss 1 is subjected to greater force. In order to balance the force on the upper truss 1, the other end of the upper truss 1 is connected to a counterweight frame 13. A counterweight block is provided in the counterweight frame 13 to balance the force on both ends of the upper truss 1. The counterweight frame 13 is located above the bridge deck.

[0052] A slewing boom 14 is mounted on the inner side of the upper and lower passages 5. The slewing boom 14 can also rotate in the horizontal plane, and a winch 15 is mounted on the slewing boom 14. The slewing boom 14 and the winch 15 correspond to the lower working platform 6 in the vertical direction, making it easy to lift the bridge inspection vehicle track and track bracket transported to the lower working platform 6 to the installation position at the bottom of the beam.

[0053] In this embodiment, the entire structure of the tooling is made of Q235B carbon steel, and each bolted part is connected by high-strength bolts and pins, ensuring the safety of the load-bearing structure of the entire device.

[0054] The installation of the tooling includes the following steps: first, arrange the first running mechanism 2 and the second running mechanism 9 on the bridge deck. Then, using a lifting device, install the upper truss 1 on the first running mechanism 2, install the intermediate lifting device 8 on the second running mechanism 9, continue to install the track hoisting frame 3 and the upper and lower channels 5 on the upper truss 1, install the track lifting device 4 on the track hoisting frame 3, install a slewing bearing and a lower working platform 6 at the bottom of the upper and lower channels 5, and install a track inside the lower working platform 6, on which a platform trolley is installed; and install an intermediate platform 10 at the bottom of the intermediate lifting device 8. The above assembly operations are all performed using lifting equipment. After the above structures are assembled, install a counterweight frame 13 on the upper truss 1 and add counterweight blocks to maintain the force balance of the tooling. After checking that the overall force structure of the tooling is correct, arrange and debug the electronic control system. After debugging is completed, the lower working platform 6 is rotated to the transverse direction of the bridge via the slewing bearing and connected to the intermediate platform, completing the overall installation of the tooling. Start the tooling to conduct forward and backward tests. If it runs normally, it can be put into production.

[0055] The tooling can move freely at the bottom of the beam section and can realize the function of passing over the piers of the bridge. Because a slewing bearing is provided between the lower working platform 6 and the upper and lower channels 5, during normal operation of the tooling, the lower platform is connected to the intermediate platform 10 via a pin. When at the pier position, the connection is released, and the lower working platform 6 is rotated along the bridge via the slewing bearing. The intermediate lifting device 8 connected to the intermediate platform 10 is used to lift the intermediate platform 10 above the pier, and then pass through the pier. After passing the pier, the lower working platform 6 is rotated to the transverse direction of the bridge, and the intermediate platform 10 is lowered to be pin-connected to the lower working platform 6, restoring the normal operating state.

[0056] Since the track lifting frame 3 is equipped with a track lifting device 4, and the track lifting device 4 is located on the outside of the upper truss 1, the bridge inspection vehicle track and track bracket can be smoothly lifted from the bridge deck to the lower opening (the lower opening is the gap between the upper and lower channels 5 and the beam body) by the track lifting device 4, and the bridge inspection vehicle track and track bracket are lowered from the lower opening to the lower working platform 6. Since the lower working platform 6 is provided with a track and a platform trolley is provided on the track, the bridge inspection vehicle track and track bracket can be directly lowered onto the platform trolley, and the bridge inspection vehicle track and track bracket are pushed to the track installation position by the platform trolley, and then the track bracket is lifted to the installation position at the bottom of the beam by the slewing boom 14 and the winch 15. After the track bracket is installed, the bridge inspection vehicle track is lifted for track installation. After the bridge inspection vehicle track is installed, the tooling is moved forward and the above actions are repeated to complete the bridge inspection vehicle track layout work in sequence.

[0057] This tooling allows for the simultaneous and continuous installation of bridge inspection vehicle tracks beneath all beam sections in both river and sea environments after partial or complete erection of the beam sections, ensuring maximum utilization of on-site construction personnel and time. It can accommodate various construction operations on the bottom plates and webs of bridge beam sections in diverse environments. For example, in addition to installing inspection vehicle tracks, this tooling can also be used for beam painting, welding, and the installation of other accessories. Besides bridge beam construction in river and sea environments, it can also be used in complex construction environments such as canyons and elevated highways.

[0058] Example 2

[0059] The difference between this embodiment and embodiment 1 is that Figure 10 As shown, in this embodiment, the upper trusses 1 are provided on both sides of the intermediate lifting device 8, and both ends of the intermediate platform 10 are detachably connected to the lower working platforms 6 on both sides.

[0060] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
