Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a bridge deck construction equipment, specifically an automated bridge deck paving device. Background Technology

[0002] The rapid and diversified development of highways in China has not only increased the speed of highway construction but also driven the development of construction mechanization and machinery levels.

[0003] Currently, bridge deck paving utilizes mechanized bridge deck pavers. Existing bridge deck paving operations typically involve pumping concrete onto the pouring surface using concrete pump trucks, followed by manual finishing and leveling. This method is inefficient, labor-intensive, and produces unsatisfactory results. Furthermore, using existing bridge deck paving equipment for continuous paving often results in a fixed paving width and thickness, leading to uneven thickness when facing undulating bridge surfaces. Moreover, the paving device cannot actively adjust to different bridge widths, requiring multiple reciprocating operations to complete the paving. Utility Model Content

[0004] This invention provides an automated bridge deck paving device to address a series of problems, including low efficiency and poor construction results of manual construction, uneven paving width and thickness, and inability to be applied to bridge decks of different thicknesses when using existing bridge deck paving equipment.

[0005] This utility model is achieved using the following technical solution:

[0006] An automated bridge deck paving device includes a multi-unit connected truss. Triangular support frames are installed above the free ends of both trusses. A pair of hydraulic rods are installed at the outer end of each triangular support frame. A traveling wheel is mounted on the piston portion of each hydraulic rod, and the traveling wheel engages with a track laid on the bridge railing. A three-dimensional laser control device connected to a field control system is installed at the middle of the free ends of each truss, below the triangular support frames. A control console connected to the field control system is installed in the middle of the truss. A leveling scraper is installed at the rear of the lower end of the truss, and two rows of pushing rollers are installed at the front of the lower end of the truss.

[0007] In implementation, it includes a truss with multiple connected units. The truss consists of several standard truss units connected in sequence. Fixed truss units are installed on the free ends of the standard truss units located at the edges. Triangular support frames are installed above the free ends of the trusses on both sides. That is, a triangular support frame is installed at the top of each fixed truss unit. A pair of hydraulic rods are installed at the outer end of each triangular support frame. Each hydraulic rod is independently controlled. A traveling wheel is installed on the piston part of the hydraulic rod. The traveling wheel cooperates with the track laid on the bridge railing to realize the overall forward and backward movement.

[0008] The free ends of the trusses are equipped with three-dimensional laser control devices connected to the field control system. Specifically, the free ends of the fixed truss units are equipped with three-dimensional laser control devices connected to the field control system. The hydraulic rods receive signals from the three-dimensional laser control devices to raise or lower both ends of the entire truss to precisely adjust the elevation and cross slope of the bridge deck pavement.

[0009] The middle of the truss is equipped with a control console that connects to the field control system. The console can adjust the paving device’s travel speed, hydraulic rod support height, and control the motor rotation to adjust the position of the movable frame when adjusting the width, and can also output field construction parameters in reverse.

[0010] A leveling scraper is installed at the rear of the lower end of the truss. The leveling scraper includes a standard scraper section and a scraper extension section. The standard scraper section is installed at the lower end of the standard truss unit of the truss, and the length of each standard scraper section is the same as the length of the standard truss unit of the truss. The scraper extension section is installed at the lower end of the fixed truss unit of the truss. The outer end of the scraper extension section extends beyond the edge of the fixed truss unit and does not contact the bridge railing.

[0011] Two rows of pusher rollers are installed at the lower front of the truss. Specifically, fixed frames are installed below the two fixed truss units in a staggered manner. Each fixed frame has a pusher screw installed on it via a bearing. The pusher screw is driven by a motor on one side of the fixed frame, and a freely rotating pusher roller is installed on the other side of the fixed frame via a pair of fastening bolts. Specifically, the pusher roller has a bearing structure. The inner sleeve of the bearing is threadedly connected to the pusher screw via bolts, and the outer sleeve rotates freely. The free end of the pusher screw is installed below the standard truss unit via a movable frame. A sliding groove is provided below the standard truss unit. The top of the movable frame has a T-shaped frame that mates with the sliding groove. The lower end of the T-shaped frame is fixed with an assembly nut that mates with the pusher screw. The outer diameter of the assembly nut is smaller than that of the pusher roller to avoid friction between the assembly nut and the ground. The two pusher screws are installed below the truss via their respective fixed frames and movable frames. The two pusher screws are installed in opposite directions, arranged in parallel, and aligned with the length direction of the truss.

[0012] In operation, the track is first laid on the bridge railing, and the paving device is installed on the bridge deck. The three-dimensional laser control device feeds data back to the control console, which collects the data and transmits it back to the control system. Through the instructions issued by the field control system terminal, the control console sends instructions to the hydraulic rods to achieve the purpose of paving cross slope and control paving elevation. The hydraulic rods are adjusted to adjust the pusher roller and the leveling scraper to the appropriate height. After the adjustment is completed, the signal is fed back to the field control system terminal. Similarly, the traveling wheels are started, the automatic forward mode is activated, the pusher roller rotates freely, and the leveling scraper smooths the surface to carry out the bridge deck paving work.

[0013] When the width needs to be adjusted to adapt to different bridge deck widths, the command issued by the on-site control system terminal adjusts the starter motor to drive the pusher screw to rotate, which in turn drives the pusher roller to rotate synchronously. The T-shaped frame of the movable frame slides in the sliding groove, increasing or decreasing the number of standard truss units to align the standard scraper sections. At this time, the two pusher rollers can completely cover the entire bridge deck. Different bridge deck widths can be adapted without replacing the pusher rollers. When further precise adjustment of the pusher roller position is required, the position of the pusher roller can be adjusted by adjusting the fastening bolts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides an automated bridge deck paving device that solves the problem of low precision in manual operation, realizing intelligent paving of bridge deck concrete panels, achieving precise control of construction parameters, improving construction progress and ensuring construction schedule. During the paving process, various construction parameters are precisely controlled, making the construction process more efficient and orderly, providing a solid guarantee for the smooth progress of the project, effectively shortening the construction cycle, and laying a good foundation for the timely completion of the project.

[0023] The free end of the truss 1 is equipped with a three-dimensional laser control device 8 located below the triangular support frame 10. The three-dimensional laser control device 8 is connected to the field control system. That is, the free end of the fixed truss unit 101 is equipped with a three-dimensional laser control device 8. The three-dimensional laser control device 8 is connected to the field control system. The hydraulic rod 3 receives the signal from the three-dimensional laser control device 8 and raises or lowers both ends of the entire truss 1 to precisely adjust the elevation and cross slope of the bridge deck pavement.

[0024] The middle part of the truss 1 is equipped with a control console 5 that is connected to the field control system. The control console 5 can adjust the travel speed of the paving device, the support height of the hydraulic rod, and the position of the movable frame 12 when adjusting the width by issuing commands from the field control system terminal. It can also output the field construction parameters in reverse.

[0025] A leveling scraper 6 is installed at the rear of the lower end of the truss 1. The leveling scraper 6 includes a standard scraper section 601 and a scraper extension section 602.

[0026] like Figure 3 , 4As shown: Two rows of pusher rollers 7 are installed at the lower front of the truss 1; specifically, a fixed frame 11 is installed below the two fixed truss units 101 in a staggered manner, and a pusher screw 9 is installed on each fixed frame 11 via a bearing. The pusher screw 9 is driven by a motor 13 on one side of the fixed frame 11, and a freely rotating pusher roller 7 is installed on the other side of the pusher screw 9 via a pair of fastening bolts 14. Specifically, the pusher roller 7 has a bearing structure, the inner sleeve of the bearing is threadedly connected to the pusher screw via bolts, and the outer sleeve rotates freely.

The control console sends the instructions to the hydraulic rod 3 through the instructions issued by the field control system terminal to achieve the purpose of paving cross slope and control paving elevation. The hydraulic rod 3 is adjusted to adjust the push roller 7 and the leveling scraper 6 to the appropriate height. After the adjustment is completed, the signal is fed back to the field control system terminal. Similarly, the walking wheel 2 is started, the automatic forward mode is activated, the push roller 7 rotates freely, and the leveling scraper 6 is used to level the surface and carry out the bridge surface paving work.

[0028] When the width needs to be adjusted to adapt to different bridge deck widths, the command issued by the on-site control system terminal adjusts the start motor 13 to drive the pusher screw 9 to rotate, which drives the pusher roller 7 to rotate synchronously. The T-shaped frame 1201 of the movable frame 12 slides in the sliding groove, increasing or decreasing the number of standard truss units 102 to align the scraper standard sections 601. At this time, the two pusher rollers 7 can completely cover the entire bridge deck. Different bridge deck widths can be adapted without replacing the pusher rollers 7. When further precise adjustment of the position of the pusher rollers 7 is required, the position of the pusher rollers 7 can be adjusted by adjusting the fastening bolts 14.
