Description

Technical Field

[0001] This invention is a prestressed concrete cap beam construction and maintenance device, belonging to the field of bridge construction and maintenance technology. Background Technology

[0002] The large-span, long cantilever corrugated steel web prestressed concrete cap beam has a large span, long cantilever, and large concrete pouring volume. After pouring, it is necessary to spray water for curing in time to prevent cracks caused by excessive temperature difference between the inside and outside.

[0003] The existing maintenance methods have obvious shortcomings: the bridge lines are long and the cap beams extend a long distance, requiring manual watering by walking back and forth with water hoses, which is time-consuming and labor-intensive for each maintenance; manual maintenance relies on experience, which can easily lead to local over-wetting or local dryness, especially the curved surfaces of large cantilever arms and corrugated steel webs, which are difficult to cover and are prone to cracking; and they cannot be matched with large cantilever cap beams of different widths and curvatures, resulting in poor versatility. Summary of the Invention

[0033] Motor 1401 drives the walking wheel 1402 to move along the flange of the cover beam; gear set 15 links the telescopic rods 17 on both sides to extend and retract synchronously, and in conjunction with the hydraulic telescopic structure 16, adjusts the lateral width to automatically adapt to different cover beam widths.

[0034] Specifically: The entire machine is hoisted and placed above the flanges on both sides of the cover beam, so that the left traveling frame 11 and the right traveling frame 12 rest on the top surfaces of the left and right flanges respectively; the hydraulic telescopic structure 16 is activated, and the hydraulic cylinder 1603 pushes the hydraulic rod 1604 to extend and retract, thereby driving the transverse telescopic frame 1601 to extend and retract, changing the distance between the left and right traveling frames to adapt to different cover beam widths; the gear set 15 drives the first bevel gears 1504 on both sides to rotate synchronously through the second bevel gear 1503, so that the telescopic rods 17 on both sides extend and retract synchronously, ensuring that the left and right traveling frames are at the same height and the entire machine is horizontal; the motor 1401 is started, driving the traveling wheel 1402 to rotate, and the entire machine moves at a constant speed along the length of the cover beam to achieve automatic continuous maintenance.

[0035] See Figures 4-7The arc of the arc-shaped truss 21 perfectly matches the arc-shaped top surface of the large cantilever beam and the curved surface of the corrugated steel web. The angle adjustment component 23 includes a corner block 2301. The top surface of the corner block 2301 has a concave arc surface that matches the bottom arc surface of the arc-shaped truss 21. A groove 2302 is provided at the center of the top of the corner block 2301, and a semi-circular groove 2303 is provided at the center of the groove 2302. The bottom center of the arc-shaped truss 21 is located at... The wall has a slot 2304 and side slots 2305 on both sides. The bottom of the side slots 2305 has an arc-shaped groove 2306. The inner bottom wall of the side slots 2305 has a sliding fastening block 2307. The bottom of the fastening block 2307 has a limiting rod 2308. The limiting rod 2308 passes through the arc-shaped groove 2306 and is fixedly connected to the inside of both sides of the corner block 2301. A worm gear is installed in the cavity between the slot 2304, the groove 2302 and the semi-circular groove 2303. The components include: a water tank 2309 located at the bottom center of corner block 2301, several atomizing nozzles 2310 at the bottom of water tank 2309, and a conduit 25 connected at one end to the side of water tank 2309; the worm gear assembly includes a worm gear 2311 fixed in slot 2304, a worm 2312 meshing with worm gear 2311 in semi-circular slot 2303, fixing plates 2313 at both ends of worm 2312, an extension plate 2314 at the bottom of fixing plate 2313, the inner side of extension plate 2314 fixed at the bottom center of both sides of corner block 2301, the input end of worm 2312 electrically connected to motor 2315 installed on the outer wall of fixing plate 2313, an electromagnetic control valve and a flow sensor at the upper connection port of atomizing nozzle 2310, and a constant temperature heating component inside water tank 2309 electrically connected to an external control switch.

[0036] The curved truss 21 matches the curved shape of the large cantilever arm and the curved surface of the corrugated steel web; the worm gear drives the corner block 2301 to rotate, adjusting the spray angle and eliminating blind spots on the curved surface; the high-pressure water pump draws water to the water storage tank 2309, and the atomizing nozzle 2310 atomizes the water evenly; the electromagnetic control valve controls the zone, and the flow sensor monitors in real time to ensure even watering without overlap or leakage.

[0037] Specifically: the telescopic boom 24 extends and retracts to adjust the height of the arc-shaped truss 21 above the ground, matching the height of the cap beam; the pitch angle of the spray head is adjusted by the angle adjustment component 23, so that the water mist vertically covers the arc surface, sides, and web; after water supply, the atomizing nozzle 2310 sprays out a fine water mist, evenly covering the entire curved surface without dry spots or gaps; the motor 2315 is started, driving the worm gear 2312 to rotate, the worm gear meshes with the worm wheel 2311, driving the corner block 2301 to achieve a pitch rotation of 0–90°; after adjustment, the motor is powered off and self-locked, fixing the spray angle; the water tank 2309 collects the water supply and evenly distributes it to each atomizing nozzle 2310, ensuring uniform spraying without blind spots.

[0038] See Figure 1 The limiting and anti-deviation mechanism 4 includes an anti-detachment baffle 41, an outer shaft 42, a support plate 43, a guide wheel 44, and a travel limiter 45; an outer shaft 42 is provided at the center of the outer side of the traveling wheel 1402, a support plate 43 is provided at the outer end of the outer shaft 42, and a guide wheel 44 is provided at the lower outer side of the support plate 43; an anti-detachment baffle 41 is sleeved on the outer shaft 42 outside the traveling wheel 1402, and a travel limiter 45 is provided at the bottom of the anti-detachment baffle 41.

[0039] The guide wheel 44 fits against the side of the flange plate to guide the machine during movement and prevent it from veering off course. The anti-detachment baffle 41 blocks the outside of the traveling wheel to prevent the machine from slipping off the flange plate. The cap beam is equipped with travel limiters 45 at both ends. After the travel is triggered, the machine will automatically stop and reverse to prevent collision.

[0040] When in use, first hoist the device to the starting end of the cover beam, start the hydraulic telescopic structure 16, adjust the transverse telescopic frame 1601 according to the width of the cover beam, so that the two side traveling wheels 1402 are in contact with the flange plate; then start the gear set 15, adjust the length of the telescopic rod 17, and calibrate the level of the frame.

[0041] Next, the angle adjustment component 23 is activated. The motor 2315 drives the worm gear 2312 to rotate the worm wheel 2311, so that the arc-shaped truss 21 corresponds to the arc-shaped top surface of the cap beam and the curved surface of the corrugated steel web. The angle of the atomizing nozzle 2310 is adjusted to ensure that the spray covers all areas.

[0042] Then add maintenance water to the vehicle water tank 31, start the high-pressure water pump, and the water enters the water storage tank 2309 through the pipe and hose. The atomizing nozzle 2310 sprays out a uniform water mist.

[0043] Start the walking drive assembly 14, and the motor 1401 drives the frame to walk at a constant speed to achieve continuous maintenance along the entire length;

[0044] The heating element is turned off when the temperature is high and the constant temperature heating element is turned on when the temperature is low; the flow sensor monitors in real time and automatically alarms when there is a blockage.

[0045] After maintenance is complete, shut down the machine, place the device at the end, and replenish water periodically.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
