Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge construction, and in particular to a prefabricated component maintenance device and a maintenance process for road and bridge construction. Background Art

[0002] Precast concrete components are concrete parts that are prefabricated in a factory or on site according to design specifications. After these components are formed, they must be cured under specific moisture and temperature conditions to ensure that the newly poured concrete can harden normally or faster and increase its strength.

[0003] Concrete curing usually adopts the method of film sprinkling, which requires continuous moistening. However, in actual operation, we found that there are some problems with the existing film sprinkling curing technology: the film on the prefabricated parts is prone to wrinkles or damage. In addition, without sprinkling water, the film lacks sufficient adhesion and is easily blown by the wind; and in the process of sprinkling water, the impact of the water flow will cause the film to move, resulting in film failure and insufficient local wetness on the surface of the prefabricated parts, which will cause cracking during the curing process and affect the quality of the prefabricated parts. To this end, in response to the above problems, a prefabricated part curing device and a curing process for road and bridge construction are proposed to solve the above problems.

In the present invention, by swinging the first adjusting rod backward, the teeth at the bottom end thereof mesh with the teeth of the second adjusting rod to make it turn. Since the rotation center of the second adjusting rod is higher than the center axis of the leveling shaft, the rotation drives the pressure rod to squeeze the leveling shaft. The leveling shaft is suspended in the air after the limit spring is squeezed by the sliding block, so that the pressure rod locks the curing roll film and the leveling shaft, making it convenient to push the moving frame plate, and can ensure that the curing roll film remains fixed before reaching the designated laying position, thereby reducing the waste of curing roll film caused by the rolling of the roll film shaft.

The top of the slide 6 is fixedly connected to the limit spring 7, and the limit spring 7 is used to limit and reset the sliding block 8.

[0016] The bottom end of the limit spring 7 is fixedly connected with a sliding block 8, and the outside of the sliding block 8 is slidably connected to the inside of the slide groove 6. There are two sliding blocks 8, and the leveling shaft 9 is indirectly fixed to the moving frame 1 through the sliding block 8. The middle part of the sliding block 8 is rotatably connected with the leveling shaft 9. The leveling shaft 9 will contact the ground and roll during the movement of the device, pulling and leveling the curing film 4 to prevent wrinkles on the curing film 4. The middle part of the sliding block 8 is movably connected with a camshaft disc 10. When the leveling shaft 9 rotates, it will synchronously drive the camshaft disc 10 to rotate. The camshaft disc 10 is a structure of discs on both sides of the middle cam.

[0017] The front and rear sides of the mobile frame 1 are rotatably connected with the center roller 11, and the center roller 11 provides a stable support point for the rotation of the swing rod 12, so that the swing rod 12 can swing around the center roller 11 under the rotation of the camshaft disc 10.

A plurality of water-saving nozzles 14 are arranged on the outside of the through pipe 13. The swing rod 12 converts the rotation of the camshaft disc 10 into its own swing, and then drives the through pipe 13 and the water-saving nozzle 14 to swing, realizing the swing spraying of the water flow, further expanding the watering coverage, and enabling the maintenance roll film 4 to absorb water more evenly, which is conducive to ensuring the maintenance quality of the road and bridge prefabricated parts.

[0018] Connecting pipes 15 are provided on both the front and rear sides of the water tank 5. The bottom ends of the connecting pipes 15 are fixedly connected to the front and rear sides of the water-saving sprinkler 14. The connecting pipes 15 serve to transport the water in the water tank 5 to the water-saving sprinkler 14, thereby realizing the connection of the water source from the water tank 5 to the spraying component.

[0019] refer to Figure 1 , Figure 7 and Figure 8The front and rear sides of the movable frame 1 are provided with fixing parts for locking the curing roll film 4, and the fixing parts include a first positioning roller 16, the first positioning roller 16 is fixedly connected to the front and rear sides of the outside of the movable frame 1, the outside of the first positioning roller 16 is rotatably connected to the first adjusting rod 17, the side of the first adjusting rod 17 close to the water tank 5 is slidably connected to the front and rear sides of the movable frame 1, the front and rear sides of the outside of the movable frame 1 are fixedly connected to the second positioning roller 18, the outside of the second positioning roller 18 is rotatably connected to the second adjusting rod 19, and the top teeth of the second adjusting rod 19 are meshed with the bottom teeth of the first adjusting rod 17. When the first adjusting rod 17 is swung backward, the first adjusting rod 17 rotates, and the teeth at the bottom end engage with the teeth of the second adjusting rod 19, causing the second adjusting rod 19 to turn. Since the rotation center of the second adjusting rod 19 (the second positioning roller 18) is higher than the center axis position of the leveling shaft 9, the turning of the second adjusting rod 19 will drive the pressure rod 23 to squeeze the outside of the leveling shaft 9. After the leveling shaft 9 is squeezed, the limit spring 7 is squeezed through the sliding block 8, so that the leveling shaft 9 is suspended in the air, so that the pressure rod 23 locks the curing film 4 and the leveling shaft 9, which is convenient for the user to keep the curing film 4 fixed when pushing the movable frame 1.

[0020] The second adjusting rod 19 is slidably connected to the front and rear sides of the movable frame 1 on one side close to the water tank 5, and the middle part of the first adjusting rod 17 is fixedly connected to the second fixed roller 21, and the middle part of the second adjusting rod 19 is fixedly connected to the first fixed roller 20, and the outer parts of the second fixed roller 21 and the first fixed roller 20 are sleeved with a tension spring 22, and the bottom end of the second adjusting rod 19 is fixedly connected to a pressure rod 23, and the outer part of the pressure rod 23 is engaged with the outer part of the leveling shaft 9, and the front and rear sides of the pressure rod 23 are rotatably connected to auxiliary wheels 24, and the top end of the first adjusting rod 17 is fixedly connected to a push rod 25, and the push rod 25 connects the two first adjusting rods 17 to realize the common rotation of the first adjusting rods 17 in the front and rear positions. At the same time, the push rod 25 also provides a convenient operating handle for the user, which makes the operation of the fixed part more labor-saving and convenient, and improves the human-computer interaction of the device.

[0021] refer to Figure 6 The top right side of the mobile frame 1 is fixedly connected with a handrail 26. The user can drive the mobile frame 1 to move by pulling the handrail 26, thereby driving the entire device to move on the road. The left side of the interior of the installation slot 2 is detachably connected with a loading bucket 27. The bottom end of the loading bucket 27 is rotatably connected with a cleaning shaft 28. When the mobile frame 1 moves, the cleaning shaft 28 will first contact the ground and roll, and absorb and collect dust and other debris on the road into the loading bucket 27, which helps to improve the cleanliness of the road environment and prevent debris from causing adverse effects on the laying of the maintenance roll film 4 and the maintenance of road prefabricated parts.

[0022] A maintenance process for prefabricated parts for road and bridge construction, according to the above-mentioned maintenance device for prefabricated parts for road and bridge construction, the specific method comprises the following steps; S1, start: the user starts the water pump of the water tank 5 through the control terminal, and the water is sent to the through pipe 13 through the connecting pipe 15, and sprayed out by the water-saving nozzle 14. S2, cleaning: Pull the handrail 26 to drive the movable frame 1 forward, and the front cleaning shaft 28 rolls to absorb and collect road dust and other debris into the loading bucket 27. S3. Laying and spraying curing liquid: The leveling shaft 9 in the middle of the mobile frame 1 rolls in contact with the ground, pulling and leveling the curing film roll 4 to prevent wrinkles. At the same time, the leveling shaft 9 rotates to drive the camshaft disc 10, so that the swing rod 12 pushes the through pipe 13 and the water-saving nozzle 14 to swing, and evenly sprays water to the curing film roll 4.

[0023] S4. Locking the film roll: When there is no need to lay the curing film roll 4, first cut the film roll, then swing the first adjusting rod 17 backward, and turn the second adjusting rod 19 through the engagement of teeth, driving the pressure rod 23 to squeeze the leveling shaft 9, making it suspended in the air, locking the curing film roll 4 and the leveling shaft 9, making it convenient to push the moving frame 1, and preventing the curing film roll 4 from rolling and wasting in advance.

[0024] Working principle: When in use, the water tank 5 is controlled by the external control end to drive the water pumps at the front and rear positions to transport water to the connecting pipe 15, so that the water flows smoothly into the through pipe 13 through the connecting pipe 15 and is sprayed out from the water-saving nozzle 14. After that, the handrail 26 is pulled to drive the movable frame 1 to move. At this time, the cleaning shaft 28 at the front side of the movable frame 1 will first contact the ground and roll, so as to absorb dust and other debris on the road and collect them into the loading bucket 27. Then, in the middle of the movable frame 1, the leveling shaft 9 will also contact the ground and roll, and pull the maintenance roll film 4 to level the maintenance roll film 4 laid on the ground to prevent wrinkles in the maintenance roll film 4. In addition, camshaft discs 10 are arranged on the front and rear sides of the leveling shaft 9, and the middle part of the camshaft disc 10 is a cam. When the leveling shaft 9 rotates, the leveling shaft 9 will synchronously drive the camshaft disc 10 to rotate. After the camshaft disc 10 rotates, the swing rod 12 in the camshaft disc 10 will slide on the cam through the roller at one end, so that the swing rod 12 synchronously drives the through pipe 13 and the water-saving nozzle 14 to swing with the first positioning roller 11 as the center under the push of the cam outer wheel expansion, so as to realize the area of ​​water spraying on the maintenance roll film 4, avoid the situation of excessive or insufficient local spraying, thereby ensuring the consistency of the road maintenance effect and further increasing the water absorption of the maintenance roll film 4.

[0025] When the user does not need to lay the maintenance film 4, the user can first cut the maintenance film 4, and then swing the first adjusting rod 17 backward. When the first adjusting rod 17 rotates, the teeth at the bottom will engage with the teeth of the second adjusting rod 19, and the second adjusting rod 19 will turn. At this time, since the second positioning roller 18, the center of rotation of the second adjusting rod 19, is higher than the center axis position of the leveling shaft 9, the turning of the second adjusting rod 19 will drive the pressure rod 23 to squeeze the outside of the leveling shaft 9. After the leveling shaft 9 is squeezed, the limit spring 7 is squeezed by the sliding block 8, so that the leveling shaft 9 is suspended in the air, so that the pressure rod 23 locks the maintenance film 4 and the leveling shaft 9, thereby facilitating the user to push the moving frame 1, ensuring that the maintenance film 4 remains fixed before the moving frame 1 reaches the specified laying position, and reducing the waste of the maintenance film 4 caused by the rolling of the film shaft 3.
