Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to an automatic maintenance device for hollow thin-walled high piers. Background Art

[0002] Hollow thin-walled high piers are a common structural form in bridge projects. Hollow thin-walled high piers refer to pier structures that are similar in transverse length to general piers, but smaller in longitudinal length, and have a hollow interior. In mountainous areas with undulating terrain and deep valleys, hollow thin-walled high piers can adapt to terrain changes and cross obstacles such as deep valleys and rivers with a smaller amount of engineering work.

[0003] Hollow thin-walled high piers are generally cast using the mold-turning construction process. Specifically, the shape of the hollow thin-walled high pier is first enclosed by a template, and concrete is poured into the template. After the concrete solidifies, the template is removed and the concrete is watered for curing. Concrete requires a certain humidity environment during the hardening process. Watering can keep the concrete surface moist to prevent the water on the concrete surface from evaporating too quickly. At the same time, keeping the concrete surface moist is conducive to improving the concrete's anti-carbonation ability. Carbonation will reduce the alkalinity of concrete, thereby weakening the protective effect on steel bars, causing steel bars to rust and affecting the durability of the structure. Watering curing keeps the concrete in a moist state, which can slow down the carbonization process and extend the service life of the structure.

[0004] The existing watering maintenance method generally adopts the hydraulic climbing formwork construction process. Specifically, after the concrete reaches the climbing strength of the hydraulic climbing formwork, the workers connect the hydraulic climbing formwork to the concrete, and the workers sprinkle water on the hydraulic climbing formwork. In this method, due to the large volume of the hollow thin-walled high piers, it takes a long time for workers to install the hydraulic climbing formwork and the work intensity is high. At the same time, it is difficult for workers to control the spraying amount during the spraying process, which will result in a waste of water resources. Summary of the invention

The driving member 43 drives the driving wheel 42 to rotate, so that the driving assembly 4 moves along the direction of the track 3.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the spray assembly 5 includes a pump body 52, a connecting block 51, a first cleaning pipe 56 and a spray pipe 54. The driving block 41 and one end of the connecting block 51 are detachably connected by bolts, and the pump body 52 is connected to the other end of the connecting block 51. A connecting plate 53 is provided at one end of the pump body 52. ​​The connecting plate 53 and the connecting block 51 are detachably connected by bolts.

The pump body has an inlet and two outlets. The water suction pipe 55 is connected to the water tank on the ground. The spray pipe 54 is One end is bent toward the template group 2, which is used to realize the spray maintenance of the hollow thin-walled high pier 1. The spray assembly 5 is connected in a detachable connection mode, which is not only convenient for disassembly and assembly, but also convenient for subsequent inspection and replacement of the spray assembly 5. One end of the driving block 41 is provided with a cleaning assembly that is detachable by bolts. The cleaning assembly includes a supporting pad 44, one end of the supporting pad 44 is bent, and a second cleaning pipe 411 is provided inside the supporting pad 44.

There is a A connector B is provided, and the connector B can be removed from the template group A. The connection between the connector B and the template group A is a hook connection. The connector A is a flexible rope. When the template group A is separated from the hollow thin-walled high pier 1, the template group 2 is parallel to the connector B. The connector B suspends the template group 2 in the air, so that there is a gap between the template group 2 and the hollow thin-walled high pier 1. With this structure, the template group 2 is disassembled by using the connector B, which is convenient for the subsequent spray maintenance of the hollow thin-walled high pier 1. The second cleaning pipe 411 is arranged opposite to the inner wall of the template group 2, and the pump body 52 draws out the water in the water tank and sprays it from the first cleaning pipe 56 and the spray pipe 54. The spray Tube 54 sprays the surface of the hollow thin-walled high pier 1, and the second cleaning tube 411 sprays and cleans the inner wall of the formwork group 2. Since there will be some concrete on the inner wall of the formwork group 2 after each disassembly of the formwork group 2, it is necessary to moisten the inner wall of the formwork group 2 before disassembling it and scrape off the concrete. After the cleaning component is set, the inner wall of the formwork group 2 can be sprayed before the formwork group 2 is disassembled, so that the concrete can be moistened in advance, and it can be easily dismantled directly after it is completely dismantled. The support pad block 44 can also balance the weight of the spray assembly 5 on the drive block 41, so that the movement process of the drive assembly 4 is more stable, and the spraying process is more stable at the same time.

[0034] This structure is simple and compact. After the formwork group 2 is disassembled, the spray assembly 5 is directly used to spray the formwork group 2 and the hollow thin-walled high pier 1, taking into account the functions of spraying maintenance of the hollow thin-walled high pier 1 and spraying cleaning of the formwork group 2, thereby avoiding the tedious operation of cleaning on the ground, further improving the disassembly and assembly efficiency of the formwork group 2, and improving the maintenance efficiency and casting efficiency of the hollow thin-walled high pier 1.

[0035] Working principle: first build several groups of template groups 2, align one end of the support rod A with the positioning hole Ⅰ211 and screw in the bolts to fix the support rod A and the template Ⅰ21, lift the guide rail Ⅰ31 to the outside of the template Ⅰ21 by a crane, align the other end of the support rod A with the positioning hole Ⅱ35 and screw in the bolts to fix the support rod A and the guide rail Ⅰ31, assemble the drive assembly 4, and then connect the connecting block 51 with the driving block 41 by bolts, install the spray assembly 5 on the other end of the connecting block 51, connect the connecting plate 53 to the connecting block 51 by bolts, connect the support pad 44 to the driving block 41, and then connect the first cleaning pipe 56 and the second cleaning pipe 411, connect the drive assembly 4 to the track 3, and extend the driving wheel 42 into the groove 34, align one end of the support rod A with the positioning hole Ⅰ211 and screw in the bolts to fix the support rod A and the template Ⅱ22, lift the guide rail Ⅱ32 to the outside of the template Ⅱ22 by a crane, align the other end of the support rod A with the positioning hole Ⅱ 35 is aligned and the bolts are screwed in to fix the support rod A and the guide rail II 32, and then one end of the connecting rail 33 is plugged into the guide rail I 31, and the other end is plugged into the guide rail II 32, so that the track 3 is annular as a whole, and the pumping pipe 55 is placed in the water tank. When the concrete in the template group 2 solidifies, the bottom template group 2 is removed, and the template I 21 and the template II 22 are respectively hung on the lower end of the support rod A by the connecting piece B, and the driving member 43 and the pump body 52 are driven by the electric control. When the driving assembly 4 is running, the pumping pipe 55 is placed in the water tank. When the concrete in the template group 2 solidifies, the bottom template group 2 is removed, and the template I 21 and the template II 22 are respectively hung on the lower end of the support rod A by the connecting piece B, and the driving member 43 and the pump body 52 are driven by the electric control. During the operation, the pump body 52 pumps out water and sprays it from the spray pipe 54, continuously sprinkling water on the surface of the hollow thin-walled high pier 1 for maintenance. At the same time, water is also sprayed from the second cleaning pipe 411 to clean the inner walls of the template I21 and the template II22. After cleaning, the template group 2 is removed from the connecting piece B, cleaned again on the ground, and then overlapped on the top of the existing template group 2. As the hollow thin-walled high pier 1 is poured layer by layer, the automatic maintenance device is removed and installed according to the position of the template group 2.

[0036] Embodiment 2

[0037] like Figure 6 , Figure 7 , Figure 8 As shown, a winding assembly 6 is provided on one side of the support rod A, and the winding assembly 6 includes a reel 62, a support Ⅰ61, a motor Ⅰ63 and a pull rope 64. The support Ⅰ61 is fixedly arranged on one side of the support rod A, and the reel 62 is rotatably connected inside the support Ⅰ61. The motor Ⅰ63 drives the reel 62 to rotate. One end of the pull rope 64 is wound around the reel 62, and the other end is detachably connected to the positioning hole Ⅰ211 of the removed template group 2. After the pull rope 64 is connected to the template group 2, the pull rope 64 is temporarily in a relaxed state between the template group 2 and the reel 62. The template group 2 is not subjected to the tension of the pull rope 64 and is in a vertical state. The removed template group 2 is suspended in the air, parallel to the hollow thin-walled high pier 1, and the pull rope 64 is inclined (such as Figure 6When the driving motor I 63 is working, the reel 62 retracts the pull rope 64, and the pull rope 64 is first stretched straight and then the lower end of the template group 2 is stretched inward, so that the lower end of the template group 2 moves toward the hollow thin-walled high pier 1. An abutment assembly 7 is provided on the other side of the support rod A. The abutment assembly 7 includes a support II 71, a motor II 73 and a telescopic member 72. The support II 71 is connected to one side of the support rod A. The telescopic member 72 is hinged in the support II 71, and the motor II 73 is connected to the telescopic member 72. The telescopic member 72 is a cylinder, and can also be other The structure is retractable. When the template group 2 is removed, there is a gap between the template group 2 and the hollow thin-walled high pier 1. The driving motor II 73 rotates, so that the motor II 73 drives the telescopic member 72 to rotate to the position toward the gap. The telescopic member 72 extends and abuts against the upper end of the template group 2 and pushes the template group 2 to move, so that the upper end of the template group 2 is away from the hollow thin-walled high pier 1, and the lower end of the template group 2 is close to the hollow thin-walled high pier 1. The winding component 6 and the abutting component 7 work together to make the lower end of the removed template group 2 tilt toward the hollow thin-walled high pier 1 (such as Figure 7 As shown), in the initial state, the axis of the telescopic member 72 is retracted, and the motor II 73 drives the telescopic member 72 to be in a state perpendicular to the template group 2 where it is located, without affecting the removal of the template group 2 at the lower end.

[0038] like Figure 6 , Figure 7 , Figure 8 As shown, since the spray pipe 54 is directed toward the hollow thin-walled high pier 1 and there is a distance between the spray pipe 54 and the hollow thin-walled high pier 1, part of the liquid is sprayed on the hollow thin-walled high pier 1 during the spraying process and then splashed outward, resulting in a waste of water resources. At the same time, the second cleaning pipe 411 will also waste a lot of water resources when spraying the template group 2. The provision of the winding component 6 and the abutment component 7 can make the bottom of the removed template group 2 close to the hollow thin-walled high pier 1, and form an angle between the hollow thin-walled high pier 1 and the template group 2. When the spray pipe 54 sprays toward the hollow thin-walled high pier 1, water splashes onto the inner wall of the template group 2. When the second cleaning pipe 411 sprays toward the template group 2, water splashes onto the hollow thin-walled high pier 1, which not only avoids the waste of water resources, but also allows the template group 2 and the hollow thin-walled high pier 1 to be cleaned twice.

[0039] Working principle: After the template group 2 is removed, one end of the pull rope 64 is connected to the positioning hole Ⅰ211, and the driving motor Ⅰ63 is operated. The motor Ⅰ63 drives the reel 62 to rotate, and the pull rope 64 is contracted and wound on the reel 62. The bottom end of the template group 2 gradually approaches the direction of the hollow thin-walled high pier 1. At the same time, the driving motor Ⅱ73 is operated, and the motor Ⅱ73 drives the telescopic member 72 to rotate, so that the shaft end of the telescopic member 72 is aligned with the removed template group 2, and then the telescopic member 72 is driven to work, and the shaft of the telescopic member 72 extends out and abuts against the template group 2, pushing the upper end of the template group 2, so that the template group 2 and the hollow There is an angle between the hollow thin-walled high pier 1. At this time, the spray pipe 54 and the second cleaning pipe 411 are working, which can greatly reduce the consumption of water resources during the spraying process and increase the efficiency of spraying. When the spraying is completed, the telescopic member 72 is first contracted, and then the motor II 73 is driven to work. The motor II 73 drives the telescopic member 72 to rotate, so that the telescopic member 72 is in a state perpendicular to the template group 2 where it is located, and the motor I 63 is driven to work, so that the pull rope 64 is loosened on the reel 62, and the template group 2 is gradually reset, completing the spraying of the hollow thin-walled high pier 1 and the cleaning of the template group 2.
