Description

Technical Field

[0001] This utility model relates to the field of turnout sleeper spraying maintenance technology, and more specifically, to a spraying device for the maintenance of high turnout sleepers. Background Technology

[0002] High-strength turnout sleepers are special high-strength sleepers designed for railway turnout areas. They are designed to withstand the complex mechanical environment and special loads of the turnout area. Currently, high-strength turnout sleepers require spray curing after molding and demolding. The significance of spray curing is as follows: 1. Inhibits moisture evaporation After demolding, the rapid evaporation of moisture on the surface of concrete sleepers can easily lead to shrinkage cracks. The spraying system can maintain a relative humidity of over 90% through high-frequency moist covering (spraying every 2 hours). 2. Promotes hydration reaction A continuous supply of water ensures that the cement is fully hydrated, increasing its early strength by 20%-30% and avoiding insufficient strength due to water shortage. Currently, during spraying, turnout sleepers are generally placed directly on the workshop floor for curing. However, this prevents the bottom surface of the sleepers from effectively contacting the water, resulting in uneven curing. Consequently, manual operation of hoisting equipment is required to flip the sleepers over and spray them a second time. In conclusion, the spraying curing process for turnout sleepers needs improvement. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to propose a spraying device for the maintenance of high-speed turnout sleepers.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, a spraying device for the maintenance of high-speed turnout sleepers includes a rectangular frame 1 (specifically made of corrosion-resistant high-strength alloy steel), a placement roller 2, a load-bearing plate 3, a conveying pipe 4, a lower spraying assembly, a first channel 7, a second channel 8, an upper spraying assembly, a high-pressure pump 11, and a four-way pipe 12. Several placement rollers 2 are equidistantly distributed along the length of a rectangular frame 1 that is open at the front end, rear end and top end, and the two ends of the placement rollers 2 are welded to the rectangular frame 1. Several load-bearing plates 3 are welded to the bottom of the rectangular frame 1, and the load-bearing plates 3 and the placement rollers 2 are distributed and welded one-to-one; The conveying pipe 4 is fixed inside the rectangular frame 1, and the conveying pipe 4 is connected to the lower spray assembly that is staggered with the load-bearing plate 3 and is lower than the roller 2. The first channel 7 and the second channel 8 are symmetrically fixed on the rectangular frame 1; The two sets of upper spraying components are respectively connected to the interior of the first channel 7 and the second channel 8, and the upper spraying components are arranged along the length of the first channel 7 and the second channel 8. The high-pressure pump 11 is fixed on the ground on one side of the rectangular frame 1, and the output end of the high-pressure pump 11 is connected to the four-way pipe 12 (the input end of the high-pressure pump 11 is connected to the water tank, which is not shown in the figure). The remaining three pipes of the four-way pipe 12 are connected to the delivery pipe 4, the first channel 7 and the second channel 8 respectively.

[0013] Specific implementation of this utility model solution, such as Figure 1 and Figure 2 As shown, the lower spray assembly includes a first spray pipe 5 and a first atomizing nozzle 6. Several first spray pipes 5 are fixed on the inner bottom surface of the rectangular frame 1 and are all connected to the conveying pipe 4. The first spray pipes 5 are staggered with the load-bearing plate 3 and are lower than the placement roller 2. The first atomizing nozzle 6 is connected to the top of the first spray pipe 5; To further improve the spraying range at the bottom of the turnout sleeper, the above-described embodiments are further optimized, such as... Figure 2 As shown, the first spray pipe 5 is symmetrically provided with inclined branch pipes 13 that connect to its interior, and the end of the branch pipe 13 is connected to the second atomizing nozzle 14.

[0014] Specific implementation of this utility model solution, such as Figure 1 and Figure 2 As shown, the upper spray assembly includes a second spray pipe 9 and a third atomizing nozzle 10. Several second spray pipes 9 are respectively arranged along the length of the first channel 7 and the second channel 8, and the second spray pipes 9 on the first channel 7 and the second spray pipes 9 on the second channel 8 are at different heights and are staggered. The third atomizing nozzle 10 is connected to the second spray pipe 9.

[0016] The working process of this utility model is as follows: First, place several turnout sleepers from the same batch in a row and at intervals on the placement roller 2 (i.e., multiple turnout sleepers can be sprayed and cured at one time on the rectangular frame 1). During the placement process, make the turnout sleepers basically parallel to the rectangular frame 1. At this time, the load-bearing plate 3 can bear the weight of the turnout sleepers. After several turnout sleepers are placed in sequence, the high-pressure pump 11 is started. The high-pressure pump 11 then draws water and injects it into the four-way pipe 12. The water then flows through the conveying pipe 4, the first channel 7, and the second channel 8, and is finally atomized and sprayed out from the first atomizing nozzle 6, the second atomizing nozzle 14, and the third atomizing nozzle 10. At this time, the upper surface, side surface, and bottom surface of the turnout sleepers can be sprayed and cured. (It should be noted that after the turnout sleepers at both ends of the rectangular frame 1 are placed, they will not extend beyond the outermost placement roller 2, and thus are completely within the effective spray range. Even if the placement roller 2 has a small area of ​​obstruction, most of the bottom area of ​​the turnout sleeper can still be effectively sprayed and cured. Therefore, there is no need for manual operation of the hoisting equipment to flip the sleepers and spray them again for curing the bottom. They can be directly unloaded and transferred.)
