DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , 3 As shown, a concrete maintenance device for highway engineering construction includes: tracks 1 laid on both sides of concrete; a traveling mechanism 2 moving on the track 1; a truss 3 spanning the top surface of the concrete, the truss 3 being able to be raised and lowered relative to the top of the traveling mechanism 2; a spraying mechanism 4 detachably connected to the truss 3; and a coating mechanism 5 arranged at the bottom of the truss 3.

[0027] When pouring the concrete layer of the highway, a slurry lifting machine will be used to smooth the concrete surface. The slurry lifting machine will move on the track 1. After the slurry lifting machine is used, the track 1 is directly used for concrete maintenance by this device without the need for additional paving.

[0028] The traveling mechanism 2 includes a frame 21, a motor 22, a transmission belt 23 and a roller 24. A platform is extended at the bottom of the frame 21. The motor 22 is installed at the bottom of the frame 21. Each group of traveling mechanisms 2 has two rollers 24. The output end of the motor 22 is connected to one end of the transmission belt 23. Two transmission belts 23 are connected before and after the output end of the motor 22. The other end of the transmission belt 23 is arranged at the rear end of the roller 24. The roller 24 rotates on the track 1. When the motor 22 is started, the motor 22 drives the transmission belt 23 to rotate, thereby further moving the roller 24 on the track 1.

[0029] A protective cover 211 is provided at the bottom of the frame 21, and the protective cover 211 covers the top and rear wall of the motor 22. The protective cover 211 prevents water from splashing into the motor 22 during watering maintenance, reduces the probability of the motor 22 contacting water, and protects the motor 22 to reduce the possibility of damage to the motor 22.

[0030] A first connecting plate 212 protrudes from the top side wall of the frame 21, and a second connecting plate 31 protrudes from the top side wall of the truss 3. An adjusting rod 6 is screwed between the first connecting plate 212 and the second connecting plate 31. The adjusting rod 6 passes through the first connecting plate 212 and the second connecting plate 31. A handle 61 is fixed to the top of the adjusting rod 6. By rotating the handle 61, the second connecting plate 31 is rotated along the adjusting rod 6, thereby raising and lowering the truss 3 as a whole. In the construction of expressways, different sections correspond to different concrete thicknesses. By adjusting the height of the truss 3, the components of the device are prevented from contacting the concrete to avoid friction.

[0031] The truss 3 crosses the entire concrete surface without contacting the concrete, thus avoiding footprints on the concrete surface or wheel marks on the concrete surface caused by insufficient concrete strength during early curing, ensuring that the appearance of the concrete meets the requirements and making the concrete surface smooth.

[0032] The spraying mechanism 4 includes a water tank 41, a water pipe 42, a water pump 43, a water outlet pipe 44 and a nozzle 45. The water pipe 42 connects the water tank 41 and the water pump 43, the water outlet pipe 44 connects the other end of the water pump 43, and the nozzle 45 is arranged in front of the water outlet pipe 44. The nozzles 45 are horizontally arrayed on the water outlet pipe 44. The curing water in the water tank 41 is pumped to the water outlet pipe 44 through the water pipe 42 by the water pump 43, and then sprayed out through the nozzles 45. The water sprayed by a number of nozzles 45 covers the surface of the concrete, so that the concrete can be fully cured by water.

[0033] like Figure 2 As shown, a hook 411 is provided on the side wall of the water tank 41, and a hook ring 33 is provided on the top of the truss 3. The hook 411 is hooked on the hook ring 33. In winter when the temperature is too low to perform watering maintenance, the water tank 41 can be removed for cleaning, while reducing the load on the truss 3 and alleviating the burden on the motor 22.

[0034] A water inlet 421 is provided on the side wall of the water pipe 42, and the water inlet 421 can be connected to a water pipe. If there is a water pipe that is long enough near a water source, the water tank 41 can be removed, the opening where the water pipe 42 and the water tank 41 are connected can be blocked, the water inlet 421 can be opened, and the water pipe can be inserted into the water inlet 421. As the truss 3 moves, the water pipe is stretched, and then water can be sprinkled on the concrete surface for maintenance, thereby eliminating the load on the water tank 41. When the water pipe cannot be connected, the water inlet 421 can be blocked, the water pipe 42 can be connected to the water tank 41, and the water stored in the water tank 41 can be used for maintenance.

[0035] A support plate 32 is welded to the bottom of the truss 3 , a water pump 43 is mounted on the support plate 32 , the support plate 32 supports the water pump 43 , and a water outlet pipe 44 runs through the bottom of the support plate 32 .

[0036] like Figure 4 As shown, the coating mechanism 5 includes a baffle 51, a rotating rod 52, a rotating shaft 53, a mounting rod 54 and a locking pin 55. The baffle 51 is welded to the two ends of the bottom of the truss 3, and the baffle 51 and the hook ring 33 are respectively located on the two opposite sides of the truss 3. The rotating rod 52 is rotatably connected to the baffle 51. Two clips 521 protrude from the side wall of the rotating rod 52. The rotating shaft 53 is arranged on one rotating rod 52. Extension rods 541 protrude from the two side walls of the mounting rod 54. The extension rod 541 at one end of the mounting rod 54 is rotatably connected to the rotating rod 52 through the rotating shaft 53. The rotating shaft 53 is not removable. The mounting rod 54 rotates around the rotating shaft 53 as the axis. The extension rod 541 at the other end of the mounting rod 54 can be rotated to another set of clips 521. At this time, the locking pin 55 can be screwed into the clips 521 and the extension rod 541. The side wall of the locking pin 55 is threaded and can be disassembled. When the concrete needs to be covered with film after pouring, the rotating rod 52 is rotated to make the clamping piece 521 in a horizontal state, the locking pin 55 is screwed out, the erection rod 54 is rotated out, and then the plastic roll is inserted and the locking pin 55 is tightened again, the starting point of the plastic roll is pressed with stones or wood, and the motor 22 is started to move the device to lay the plastic film on the concrete; in winter, the cotton felt roll can be inserted into the erection rod 54 and laid on the concrete for insulation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
