Detailed Implementation

[0016] like Figures 1 to 4 As shown, this utility model includes a first tracked conveyor 15-1, a power transmission assembly, a second tracked conveyor 15-2, and a third tracked conveyor 15-3, which are sequentially installed on the side bracket 17 of the carriage 18. The power transmission assembly includes a U-shaped slide bracket 10 installed on the side bracket 17 of the carriage. A worktable 1 is provided on the lower front side of the U-shaped slide bracket 10. A cam 2 is installed below the worktable 1. The front end of the cam 2 is rigidly connected to the bottom of the worktable 1 through a push rod 3. The push rod 3 moves linearly in the guide sleeve 4. The top end of the push rod 3 is connected to the worktable 1 by flange bolts. The rear end of the cam 2 is coaxially connected to the crank 5. The crank 5 forms a coaxial transmission with the cam 2 through the keyway structure. The end of the crank 5 away from the cam 2 is hinged to the connecting rod 6. The upper U-shaped groove of the U-shaped slide bracket 10 is provided with a press-fit slider 7. The press-fit slider 7 is equipped with a lubricating bushing 8. The press-fit slider 7 and the connecting rod 6 are hinged through the spherical bearing 9 to form a rotary pair. The slider 7 is connected to the press-fit head 13 through the vertical press-fit arm 12.

[0017] In this embodiment, polyurethane buffer pads 11 are provided at the bottom of the pressing head 13 and the bottom of the upper U-shaped groove of the U-shaped slide bracket 10.

[0018] In this embodiment, the first tracked conveyor 15-1 and the second tracked conveyor 15-2 are arranged horizontally, and the third tracked conveyor 15-3 is arranged at an incline. The end of the third tracked conveyor 15-3 closest to the second tracked conveyor 15-2 is at a high position, and the end of the third tracked conveyor 15-3 furthest from the second tracked conveyor 15-2 is at a low position. The first tracked conveyor 15-1 is 10cm to 20cm higher than the second tracked conveyor 15-2.

[0019] In this embodiment, a limiting baffle 14 for limiting water-filled barriers is provided on the upper side of the second tracked conveyor 15-2 near the workbench 1 on the side bracket 17 of the carriage. The limiting baffle 14 is higher than the workbench 1. The limiting baffle 14 includes a baffle seat 14-1 and a baffle 14-2. The baffle 14-2 is hinged to the baffle seat 14-1 by a torsion spring. The initial state of the baffle 14-2 is horizontal.

[0020] In actual use, the baffle 14-2 rotates downward around the connecting axis on the baffle seat 14-1. After two adjacent water-filled barriers are connected, the baffle 14-2 can automatically reset due to the action of the torsion spring.

[0021] In this embodiment, multiple water-filled barriers are placed inside the carriage 18. A locking block 21 is provided on the upper front side of the water-filled barriers along the direction of movement, and a slot 22 adapted to the locking block 21 is provided on the upper rear side of the water-filled barriers along the direction of movement.

[0022] In this embodiment, elastic roller sets 16 for limiting the movement of water-filled barriers are provided on both sides of the first tracked conveyor 15-1, the workbench 1, the second tracked conveyor 15-2, and the third tracked conveyor 15-3.

[0023] In practical use, the flexible roller assembly 16 consists of polyurethane-coated guide wheels. The radius of curvature R of the working surface of the guide wheels is greater than or equal to the minimum fillet radius of the sidewall of the water-filled barrier. The distance L between the working surfaces of the two guide wheels is equal to the maximum standard width of the water-filled barrier plus 5mm, forming a clamping and positioning mechanism that enables the water-filled barrier to be positioned laterally on the conveyor belt. The springs built into the inclined grooves of the flexible roller assembly 16 give the roller shafts an inclined floating amount, enabling adaptive guidance for water-filled barriers of different widths.

[0024] It should be noted that this embodiment realizes the fully automated operation of conveying, positioning, adjusting posture, and locking of two adjacent water-filled barrier units. By continuously placing water-filled barriers onto the first tracked conveyor, the side-mounted semi-automatic water-filled barrier assembly is achieved, which improves efficiency compared to traditional manual assembly and avoids the wear and tear of connecting parts caused by manual operation.

[0025] In use, the first tracked conveyor 15-1 and the workbench 1 are initially on the same horizontal reference plane (height difference ≤ 0.1mm) and the whole is 20cm higher than the plane of the second tracked conveyor 15-2. When the second water horse 20 is conveyed by the first tracked conveyor 15-1 to the top of the workbench 1, the limiting baffle 14 limits the position of the second water horse 20. After positioning, the assembly spindle drives the cam 2 to rotate at n=30rpm. During its descent stage, the workbench 1 is driven to descend synchronously through the power transmission component. At the same time, the cam 2 drives the rear crank 5 to rotate, and drives the pressing slide 7 to move down through the connecting rod 6. The vertical pressing arm 12 fixed to the pressing slide 7 presses down vertically at the same time. The pressing head 13 applies directional pressure, and the polyurethane buffer layer absorbs the impact energy. The vertical pressing arm 12 has a pressing speed of v = 120 mm / s (the manual hammering speed is about 50 mm / s), and a pressing force F = 200 ± 10 N (the manual operating force fluctuates by ± 50 N). The polyurethane buffer layer (3 mm thick) at the bottom of the pressing head 13 absorbs the impact energy, with a peak acceleration ≤ 5g (the manual impact reaches 15g). At this time, the locking block 21 of the second water barrier 20 engages with the locking groove 22 of the first water barrier 19 to complete the mechanical connection. The baffle in the limit baffle 14 automatically rebounds and resets after being reset by the torsion spring. The second water barrier 20 falls in 0.8 s (the manual lifting time is 3-5 s), and the verticality error is ≤ 0.05 mm / m. After assembly, the second tracked conveyor 15-2 restarts and removes the second water-filled barrier 20, at which point cam 2 stops rotating. After removal, the second tracked conveyor 15-2 stops again, positioning the second water-filled barrier 20 at the assembly station of the second tracked conveyor 15-2. Cam 2 then resumes rotation and enters the lifting phase, while the worktable 1 rises back to the preset initial height. Subsequent water-filled barrier units sequentially cycle through the above assembly process to form a continuous isolation belt (single-piece assembly cycle ≤ 5.5s). Compared to manual assembly (single-piece ≥ 30s / positioning accuracy ±5mm / uncontrollable pressure), this improves assembly efficiency, increases the water-filled barrier connection qualification rate, and reduces labor costs. The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
