DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1-3As shown, the self-propelled prefabricated beam full-section spray trolley proposed by the utility model includes a pre-buried track 1 and an external water pipe 5, a track car 2 is slidably connected to the pre-buried track 1, a mounting pole 21 is fixed to the inner side of the upper end of the track car 2, a control cabinet 22 is fixed to the outer side of the upper end of the track car 2, a water tank 3 is fixed to the middle position of the upper end of the track car 2, the external water pipe 5 is fixed to the outer side of the pre-buried track 1 and is located at the end of the pre-buried track 1, an electric control valve 51 is fixed to the upper end of the external water pipe 5, and a water inlet bucket 3 is fixed to the outer side of the water tank 3 and aligned with the end of the external water pipe 5 1. A liquid pump 4 is fixed on the upper end of the water tank 3, and a water pump 41 and a water spray pipe 42 are fixed on the liquid pump 4. The end of the water pump 41 is located in the water tank 3, and the water spray pipe 42 is fixed on the mounting pole 21, and nozzles 43 are fixed equidistantly on the inner side. A track groove 11 is opened on the upper end of the embedded track 1, and track wheels 24 are rotatably connected to the four corners of the bottom of the track car 2, and the bottom of the track wheel 24 is located in the track groove 11. A driving groove 23 is opened in the middle position of the bottom of the track car 2, and a travel motor 25 is fixed in the driving groove 23 and at a position corresponding to the track wheel 24.

[0019] A track block 6 is slidably connected to the embedded track 1, a mounting seat 61 is fixed on the upper end of the track block 6, a touch-pressure switch 62 is installed on the side wall of the mounting seat 61, a locking bolt 63 is threadedly connected to the outer side of the track block 6, a water collection groove 7 is opened on the side of the embedded track 1 away from the external water pipe 5, a filter cover plate 71 is installed at the upper opening of the water collection groove 7, and a liquid level sensor is fixed in the water tank 3.

[0020] In this embodiment, the prefabricated beam is placed between the embedded tracks 1, and then the track wheel 24 is driven by the travel motor 25 to rotate, so that the track car 2 slides on the embedded track 1. In this process, the water in the water tank 3 is pumped out by the liquid pump 4, and then sprayed from the nozzle 43 on the water spray pipe 42 to evenly spray the entire cross-section of both sides of the prefabricated beam, thereby reducing labor costs and avoiding omissions that may be caused by manual water spraying. At the same time, after the track car 2 moves to the end of the track, it will abut against the track block 6. At this time, the side wall of the track car 2 squeezes the touch switch 62, which can control the travel motor The machine 25 is driven in reverse to achieve the purpose of reciprocating water spraying. At the same time, the sliding of the track block 6 can be used to fix it at a specified position on the embedded track 1, thereby adjusting the movement distance of the track car 2 according to the length of the prefabricated beam. When the water level in the water tank 3 drops, the liquid level sensor is used for detection, so that the track car 2 can be moved to the origin position. At this time, the end of the external water pipe 5 will be aligned with the water inlet hopper 31 on the side wall of the water tank 3. The electric control valve 51 is opened to inject water into the water tank 3 through the external water pipe 5. The entire process does not require dragging of the external water pipe 5, reducing the risk of pipeline damage.
