DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] like Figure 1-Figure 4 As shown, a spray curing device for a prefabricated box beam comprises two spray curing assemblies 2 symmetrically arranged on both sides of a box beam 1, wherein the spray curing assembly 2 comprises a walking mechanism 3, a support column 4, a top surface spray assembly 5, a side spray assembly 6 and a water pump 7, wherein the support column 4 is fixed on the walking mechanism 3, the top surface spray assembly 5 is connected to the support column 4 and is located above the support column 4, and the side spray assembly 6 is connected to the middle part of the support column 4 and faces the side wall of the box beam 1.

[0028] The top surface spray assembly 5 includes an outer tube 501, an inner tube 502 and a first water tube 8, wherein the first water tube 8 is located in the inner tube 502, the inner tube 502 is located in the outer tube 501 and is slidably connected to the outer tube 501, one end of the first water tube 8 is connected to the water pump 7, and the first water tube 8 is adjusted to extend in length through the inner tube 502 and the outer tube 501;

[0029] The side spray assembly 6 includes a first sleeve 601, a second sleeve 602 and a second water pipe 9, the first sleeve 601 is rotatably connected to the support column 4, the second sleeve 602 is rotatably connected to the first sleeve 601, one end of the second water pipe 9 extends into the first sleeve 601 and the second sleeve 602, and the other end of the second water pipe 9 is connected to the water pump 7;

[0030] A nozzle 10 is provided on one side of the first water pipe 8 and the second water pipe 9 facing the box girder 1 .

[0031] Through the above technical solution, the spray maintenance component 2 is moved to one side of the box girder 1 through the walking mechanism 3, and the spray maintenance component 2 can continuously spray the box girder 1 along the length direction of the box girder 1 through the walking mechanism 3. The specific spraying process is: for the top surface spray component 5, according to the width of the box girder 1, adjust the inner tube 502 to extend to one side of the box girder 1. Since the inner tube 502 is slidably connected with the outer tube 501, it is convenient to adjust the extension distance of the inner tube 502. When the inner tube 502 is adjusted, lock the inner tube 502 and the outer tube 501 to prevent the inner tube 502 from being separated from the outer tube 501 after walking, and then start the water pump 7 to pressurize the first water pipe 8 to pump water, and spray the top surface of the box girder 1 through the first water pipe 8;

[0032] For the side spray assembly 6, the inclination angle of the first sleeve 601 and the second sleeve 602 is adjusted according to the inclination angle of the side wall of the box girder 1, so that the second water pipe 9 extending into the first sleeve 601 and the second sleeve 602 can adapt to the side wall of the box girder 1, and then the water pump 7 is started to pressurize the second water pipe 9 to pump water, ensuring that the nozzle 10 on the second water pipe 9 can effectively spray and maintain the side wall of the box girder 1.

[0033] The top surface spray assembly 5 and the side spray assembly 6 can effectively adapt to box girders 1 of different shapes, and at the same time can improve the efficiency of spray maintenance and reduce the waste of water resources.

[0034] Furthermore, a first adjusting screw 603 is provided at a position of the support column 4 corresponding to the first sleeve 601, the first adjusting screw 603 is threadedly connected to the support column 4, and the end of the first adjusting screw 603 abuts against the first sleeve 601; a second adjusting screw 604 is provided at a position of the support column 4 corresponding to the second sleeve 602, the second adjusting screw 604 is threadedly connected to the support column 4, and the end of the second adjusting screw 604 abuts against the second sleeve 602, a through hole for the second water pipe 9 to pass through is provided in the middle part of the support column 4 corresponding to the position of the first sleeve 601, and the first sleeve 601 and the second sleeve 602 are provided with a groove for the nozzle 10 on the second water pipe 9 to pass through.

[0035] Through the above technical solution, the tilt angle of the first sleeve 601 can be adjusted by screwing in and out the first adjusting screw 603, and the first sleeve 601 is supported by the thread locking of the first adjusting screw 603; the tilt angle of the second sleeve 602 can be adjusted by screwing in and out the second adjusting screw 604, and the second sleeve 602 is supported by the thread locking of the second adjusting screw 604. After the first sleeve 601 and the second sleeve 602 are adjusted, the second water pipe 9 is first passed through the support column 4 and then extended into the first sleeve 601 and the second sleeve 602, and the nozzle 10 on the second sleeve 602 is extended toward the side wall of the box beam 1 through the slot.

[0036] Furthermore, the middle part of the outer tube 501 is fixedly connected to the top plate of the support column 4, and the bottom of the outer tube 501, the bottom of the inner tube 502 and the top of the support column 4 are provided with grooves for the nozzle 10 of the first water pipe 8 to pass through, and the length of the inner tube 502 is greater than the length of the outer tube 501.

[0037] Through the above technical solution, after the inner tube 502 slides along the outer tube 501 to adjust the distance, the outer tube 501 supports the inner tube 502, and then the first water pipe 8 is extended into the inner tube 502, and the first water pipe 8 starts the supporting function through the inner tube 502, and then the nozzle 10 of the first water pipe 8 passes through the groove and goes out toward the top surface of the box girder 1.

[0038] Furthermore, the outer tube 501 is provided with a tightening screw 503 , the tightening screw 503 is threadedly connected to the outer tube 501 , and the end of the tightening screw 503 abuts against the inner tube 502 .

[0039] Through the above technical solution, after the inner tube 502 slides along the outer tube 501 to adjust the distance, the inner tube 502 and the outer tube 501 are fixed by tightening the locking screw, and the friction generated by the abutment of the locking screw can prevent the inner tube 502 and the outer tube 501 from sliding.

[0040] Furthermore, the inner tubes 502 of the two symmetrical spray maintenance assemblies 2 are connected by bolts.

[0041] Through the above technical solution, the ends of the two inner tubes 502 are connected by bolts, so that the two spray maintenance components 2 can be connected as a whole, and driven to run together by the walking mechanism 3, so that the top surface and side surfaces of the entire box girder 1 can be spray maintained. At the same time, the two separated spray maintenance components 2 are easy to move, and can be conveniently moved to the next box girder 1 position, and then connected for subsequent spraying.

[0042] Furthermore, the first water pipe 8 and the second water pipe 9 are flexible pipes, and the spray head 10 is provided with a valve.

[0043] Through the above technical solution, since the first sleeve 601 and the second sleeve 602 need to adjust the inclination angle, the second water pipe 9 uses a flexible pipe to facilitate the second water pipe 9 to bend a certain angle, which is more suitable for the side wall of the box beam 1; at the same time, since the widths of different box beams 1 are different, the inner pipe 502 needs to be adjusted, and then the second water pipe 9 of different lengths needs to be inserted, so the first water pipe 8 also uses a flexible pipe to facilitate bending adjustment. At the same time, the valve opening and closing of the nozzle 10 can be adjusted according to the area to be sprayed, which can effectively reduce the waste of water resources.

[0044] Furthermore, the water pump 7 is located on the walking mechanism 3, and the water pump 7 is connected to an external water source.

[0045] Through the above technical solution, the water pump 7 is externally connected to a water supply pipe, and the water is pumped into the first water pipe 8 and the second water pipe 9 through the water pump 7, and then the box girder 1 is sprayed.

[0046] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
