[0045] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0046] According to the specific embodiments of the present invention, Figure 1-4 As shown, the present invention provides a comprehensive maintenance device for high bridge piers, the maintenance device includes a spray system and a curtain system;

[0047] The spray system includes an annular track 6, which is arranged on the top of a support frame 7, and the support frame 7 is detachably fixed on the top of the pier 1;

[0048] A spraying vehicle 11 is guided and moved on the circular track 6, and a water spraying pipe 12 is arranged on the spraying vehicle 11, and the water spraying pipe 12 sprays water toward the outer surface of the bridge pier 1;

[0049] A water tank 9 is provided on the bridge pier 1, and the water tank 9 is connected to a water spray pipe 12 on a spray truck 11 through a telescopic hose 10. The water tank 9 is used to supply water to the water spray pipe 12 through the telescopic hose 10. In this embodiment, a water pump is provided in the water tank 9, and water pumped by the water pump is transferred to the water spray pipe 12 through the telescopic hose 10, so that the water spray pipe 12 sprays water onto the surface of the bridge pier 1.

[0050] In other embodiments, the water pump may also be arranged on the spray truck 11, in which case the telescopic hose 10 connects the water tank 9 with the water pumping end, and the water spray pipe 12 is connected to the water discharge end of the water pump.

[0051] The curtain system includes a moisture-retaining maintenance blanket 3, which surrounds and wraps around the outer periphery of the bridge pier 1;

[0052] The top of the moisturizing and curing blanket 3 is fixed to the side of the supporting frame 7;

[0053] The curtain system also includes a lifting mechanism, which is used to drive the moisturizing maintenance blanket 3 to rise or fall. When the moisturizing maintenance blanket 3 is completely fallen, the moisturizing maintenance blanket 3 is completely wrapped around the periphery of the pier 1.

[0054] After the maintenance device is installed on the top of the pier 1, the lifting mechanism is first started to completely lower the moisturizing maintenance blanket 3 so that the moisturizing maintenance blanket 3 surrounds and wraps around the periphery of the pier 1, thereby preventing the moisture on the surface of the pier 1 from being evaporated quickly after the surface of the pier 1 is sprayed and maintained, thereby achieving a better spray maintenance effect, ensuring the maintenance strength of the pier 1, and thus improving the maintenance efficiency as much as possible.

[0055] After the moisturizing maintenance blanket 3 is put into place, the spray truck 11 is started and guided to move along the circular track 6. At this time, the water spray pipe 12 on the spray truck 11 sprays water to the pier 1 from the gap between the moisturizing maintenance blanket 3 and the pier 1. The water flows along the outer surface of the pier 1 from the top to the bottom, thereby realizing the spray maintenance of the pier 1 and greatly improving the maintenance efficiency.

[0056] After the maintenance of a pier 1 is completed, the lifting mechanism is started again to lift the moisturizing maintenance blanket 3 upwards, so that the moisturizing maintenance blanket 3 can be folded and contracted for easy transportation; when the moisturizing maintenance blanket 3 is contracted into place, the entire maintenance device is installed on the next pier 1 to repeat the above maintenance work; the moisturizing maintenance blanket 3 can be used repeatedly, and the wrapping and folding operations of the moisturizing maintenance blanket 3 on the pier body are relatively simple, that is, the maintenance device of the present application is more convenient for repeated use.

[0057] The moisturizing and curing blanket 3 comprises a plastic film on the outer layer and a water-absorbing layer on the inner layer. The water-absorbing layer is made of a water-absorbing material prepolymer implanted in a non-woven fabric.

[0058] In one embodiment of the present application, in the moisturizing maintenance blanket 3, the plastic film prevents the evaporation of water too quickly, and the water-absorbing layer made of a water-absorbing material prepolymer implanted in a non-woven fabric has good water absorption. After spraying, the water-absorbing layer is filled with water and adheres closely to the surface of the pier 1, thereby achieving a better maintenance effect for the pier 1.

[0059] Specifically, the moisturizing maintenance blanket 3 is a new type of polymer concrete water-saving maintenance moisturizing film; the moisturizing film uses a plastic film as a carrier, and through the prepolymerization method, the water-absorbing material prepolymer is implanted into a special non-woven fabric, wherein the water-absorbing material is a water-absorbing resin, and the water-absorbing resin is integrated with the special non-woven fabric and the impermeable plastic film, and adheres to the polymer that can absorb 200 times its own weight of water. That is, the moisturizing maintenance blanket 3 can not only prevent rapid evaporation of water, but also has good water absorption, which is beneficial to improving maintenance efficiency.

[0060] A plurality of fixing rings 4 are arranged on the moisturizing and curing blanket 3 , and the fixing rings 4 are arranged on the outer surface of the moisturizing and curing blanket 3 .

[0062] The side of the support frame 7 is provided with a support rod extending outward, and the fixing ring 4 on the top of the moisturizing maintenance blanket 3 is fixed on the support rod. By arranging a support rod extending outside the pier 1 on the support frame 7, and fixing the top of the moisturizing maintenance blanket 3 on the support rod on the side of the support frame 7, a gap is formed between the moisturizing maintenance blanket 3 and the periphery of the pier 1, so that the water spray pipe 12 can spray the outer surface of the pier 1 from the gap between the moisturizing maintenance blanket 3 and the periphery of the pier 1 for maintenance.

[0063] The lifting mechanism includes a driving source 8 and a plurality of lifting ropes 5, and the plurality of lifting ropes 5 are evenly distributed around the moisturizing and curing blanket 3; one end of the lifting rope 5 is fixed to the bottom of the moisturizing and curing blanket 3, and the other end is fixed to the rotating output end of the driving source 8. In one embodiment of the present application, the output end is driven to rotate by the driving source 8, so that the lifting rope 5 is wound around the output end of the driving source 8, so that the lifting rope 5 is retracted, thereby driving the moisturizing and curing blanket 3 to fold upward and rise; or the lifting rope 5 is released from the output end of the driving source 8, so that the lifting rope 5 is lowered, thereby driving the moisturizing and curing blanket 3 to be lowered. Multiple lifting ropes 5 are arranged around the moisturizing and curing blanket 3 so that the force during the rising and falling process of the moisturizing and curing blanket 3 is more uniform.

[0064] In this embodiment, the driving source 8 is arranged on the top of the pier 1, and the water tank 9 is supported by a bracket to avoid interference between the lifting rope 5 and the water tank 9. In other embodiments, the driving source 8 can also be arranged above the water tank 9, and the water tank 9 can be arranged at the center of the top of the pier 1.

[0065] The lifting rope 5 passes through a plurality of fixing rings 4 arranged along one lifting rope 5 in sequence. In one embodiment of the present application, only the bottom end of the lifting rope 5 is fixed to the bottom end of the moisturizing and curing blanket 3, and the lifting rope 5 only passes through the fixing ring 4 arranged on the periphery of the moisturizing and curing blanket 3; when the lifting rope 5 is lowered, the fixing ring 4 on the moisturizing and curing blanket 3 is guided along the lifting rope 5, so that the lowering process of the moisturizing and curing blanket 3 is more uniform and stable; when the lifting rope 5 is retracted, the fixing ring 4 on the moisturizing and curing blanket 3 is folded along the lifting rope 5, so that the moisturizing and curing blanket 3 can be folded evenly, thereby making it more convenient to transport and install the curing device.

[0066] The maintenance device also includes a tightening rope 2, which is spirally wound around the outer periphery of the moisturizing maintenance blanket 3; one end of the tightening rope 2 is fixed to the bottom of the moisturizing maintenance blanket 3, and the other end of the tightening rope 2 is fixed to the spraying vehicle 11. In one embodiment of the present application, the spraying vehicle 11 is guided and moved along the circular track 6 to drive the tightening rope 2 to be gradually tightened, so that the moisturizing maintenance blanket 3 is attached to the bridge pier 1, so that the bridge pier 1 has a better maintenance effect.

[0067] A plurality of fixing rings 4 are arranged on the periphery of the moisturizing and curing blanket 3 along a spiral track; the tightening rope 2 passes through the plurality of fixing rings 4 arranged on the periphery of the moisturizing and curing blanket 3 in sequence.

[0068] In one embodiment of the present application, the fixing ring 4 on the moisture-retaining maintenance blanket 3 is arranged along a spiral trajectory, so that the tightening rope 2 can pass through multiple fixing rings 4 in sequence. Then, after the tightening rope 2 is gradually tightened, the moisture-retaining maintenance blanket 3 can be more evenly attached to the periphery of the pier 1.

[0069] The driving source 8 is a winch, one end of each of the plurality of lifting ropes 5 is connected to the rotation output end of the winch, and the winch drives the plurality of lifting ropes 5 to rise or fall synchronously.

[0070] The driving source 8 is a motor, and an I-shaped wheel is provided at the output end of the motor. One end of the plurality of lifting ropes 5 is fixed on the I-shaped wheel, and the I-shaped wheel is driven to rotate to drive the plurality of lifting ropes 5 to rise or fall synchronously.

[0071] The present application also provides a method for using the comprehensive maintenance device for high bridge piers 1. The method for using is the method for using the comprehensive maintenance device for high bridge piers 1 described above. The method for using includes:

[0072] Step 1, installing the maintenance device on the top of the pier 1;

[0074] Step 3, start the spraying vehicle 11, guide the spraying vehicle 11 along the circular track 6, drive the water spraying pipe 12 to spray water evenly toward the outer surface of the pier 1; at the same time, the spraying vehicle 11 drives a part of the tightening rope 2 to be wound around the support frame 7, and the tightening rope 2 is gradually tightened, so that the moisturizing maintenance blanket 3 is closely attached to the outer periphery of the pier 1; in order to reduce the gap between the moisturizing maintenance blanket 3 and the pier 1, so as to achieve a better maintenance effect, in the process of gradually tightening the tightening rope 2, the water spraying pipe 12 synchronously sprays water evenly toward the outer surface of the pier 1 , so that the water flows gradually from the top of the pier 1 to the bottom of the pier 1; and after the tightening rope 2 is fully tightened, the part of the moisturizing maintenance blanket 3 where the tightening rope 2 is set is close to the pier 1. Since the tightening rope 2 is spirally set, after the moisturizing maintenance blanket 3 is tightened on the pier 1, a spiral gap channel is reserved between the moisturizing maintenance blanket 3 and the pier 1; at this time, the spraying vehicle 11 continues to spray, and the water will flow from the top of the pier 1 to the bottom of the pier 1 along the spiral gap channel, so that the pier 1 is evenly sprayed and maintained;

[0075] Step 4: After the spraying maintenance is completed, the spraying vehicle 11 returns to the starting position to loosen the tightening rope 2;
