DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 4As shown in the figure, a turnover device for the steel capping beam of a portal pier according to an embodiment of the present utility model includes a guide groove 1; the guide groove 1 is arc-shaped; both ends of the guide groove 1 are provided with grooves 12; the two grooves 12 are symmetrically arranged; sliding grooves 13 are directly provided on the opposite surfaces of the grooves 12; a plurality of rotating rollers 14 are slidably connected inside the sliding grooves 13; a pulley 15 is rotatably connected to the middle of each of the plurality of rotating rollers 14; the middle of the pulley 15 extends to the outside of the groove 12; a discharge hole 16 is provided at the end of the guide groove 1; a plurality of limiting rods 17 are fixedly connected to the side wall of the guide groove 1; the plurality of limiting rods 17 are equidistantly distributed along the contour of the guide groove 1 and extend to the position of the guide groove 1 close to the discharge hole 16; the limiting rod 17 is U-shaped. During operation, slide a plurality of pulleys 15. As the plurality of pulleys 15 slide, it will drive the plurality of rotating rollers 14 to slide inside the sliding grooves 13. At this time, slide the plurality of pulleys 15 to the end of the guide groove 1. Subsequently, use a crane or other device to place the steel capping beam of the portal pier to be installed at the end of the guide groove 1. At this time, as the steel capping beam of the portal pier is placed on the top of the guide groove 1, the steel capping beam of the portal pier will come into contact with the plurality of pulleys 15. At this time, the plurality of pulleys 15 lift the steel capping beam of the portal pier above the guide groove 1. At the same time, the steel capping beam of the portal pier will slide as the plurality of pulleys 15 slide. At this time, by sliding the plurality of pulleys 15, the steel capping beam of the portal pier can be driven to slide along the contour of the guide groove 1. At this time, the steel capping beam of the portal pier slides along the contour of the guide groove 1 until it slides to the position of the discharge hole 16 and can be turned into an upright state, and then slides out from the middle of the discharge hole 16. When the steel capping beam of the portal pier slides above the guide groove 1, the plurality of limiting rods 17 can limit the steel capping beam of the portal pier, reducing the occurrence of the situation of the steel capping beam of the portal pier tipping over during the sliding process. Through the above structure, the horizontally placed steel capping beam of the portal pier can be turned into a vertical state by this device, so as to achieve the effect of turning over the steel capping beam of the portal pier, reducing the problems of waste of funds and potential safety hazards caused by the need for multiple cranes to operate simultaneously in the traditional turnover method. At the same time, by using this device to turn over the steel capping beam of the portal pier, the cumbersome working steps can be reduced, thereby reducing the working hours to a certain extent.

[0023] As Figure 1As shown, a water tank 2 is fixedly connected to the inside of the guide groove 1; two water pipes 21 are connected to the side walls of the water tank 2; through holes 22 are opened on the opposite side walls inside the guide groove 1; the two water pipes 21 penetrate the through holes 22 and extend to the inside of the groove 12. When working, multiple pulleys 15 and rotating rollers 14 slide inside the groove 12 and the slide groove 13 to drive the portal pier steel cap beam to turn over. As time goes by, certain wear will occur between the pulley 15 and the groove 12 and the slide groove 13 and the rotating roller 14. When the wear is more serious, it will make it difficult for the pulley 15 to slide inside the groove 12, thereby making it difficult to drive the portal pier steel cap beam to turn over. At this time, the lubricating liquid is filled into the water tank 2, and then the water pump placed inside the water tank 2 is started. As the water pump is started, the lubricating liquid inside the water tank 2 will fill the inside of the water pipe 21. At this time, the lubricating liquid flows along the contour of the water pipe 21 until it is sprayed out from the end of the water pipe 21. At this time, the end of the water pipe 21 enters the inside of the groove 12 through the through hole 22, so the lubricating liquid sprayed from the water pipe 21 will be sprayed into the inside of the groove 12. Through the above structure, the lubricating liquid can be sprayed into the inside of the groove 12 in time, thereby reducing the wear caused by the pulley 15 sliding in the groove 12 for a long time, and increasing the service life of the pulley 15 to a certain extent.

[0024] like Figure 2 and Figure 3 As shown, the two opposite side walls inside the guide groove 1 are provided with a plurality of liquid outlet holes 3; the plurality of liquid outlet holes 3 are evenly distributed along the outline of the guide groove 1; the bottom of the guide groove 1 is provided with a plurality of leakage holes 31; the plurality of leakage holes 31 are evenly distributed along the outline of the guide groove 1; a collecting box 32 is fixedly connected to the bottom of the guide groove 1; the collecting box 32 is directly opposite to the bottom of the plurality of leakage holes 31. When working, the lubricating liquid is sprayed on the inside of the groove 12 through the water pipe 21, so that the pulley 15 can be lubricated in time, thereby reducing the wear between the pulley 15 and the groove 12. At this time, the excess lubricating liquid sprayed by the water pipe 21 will accumulate inside the groove 12, thereby causing In order to prevent the lubricating liquid from absorbing dust, a plurality of liquid outlet holes 3 are provided on the inner wall of the guide groove 1, and then a plurality of liquid leakage holes 31 are provided on the bottom of the guide groove 1, so that the lubricating liquid can flow along the liquid outlet holes 3 to the inside of the guide groove 1, and then flow out from the liquid leakage holes 31. The outflowing lubricating liquid will directly fall into the inside of the collecting box 32. Through the above structure, the accumulation of excessive lubricating liquid in the groove 12, which causes the absorption of dust in the groove 12, can be reduced. At the same time, through the setting of the collecting box 32, the waste lubricating liquid can be uniformly collected and processed, reducing the pollution of the environment and the waste of lubricating liquid resources caused by the turbulence of the waste lubricating liquid.

[0025] like Figure 1As shown, a guide plate 4 is fixedly connected to one end of the guide groove 1 away from the discharge hole 16; the guide plate 4 is set upward. When working, by setting the guide plate 4, a crane or other equipment can be used to place the portal pier steel cap beam on the top of the guide groove 1 through the guide plate 4. At the same time, by setting the guide plate 4 to be set upward, on the one hand, it is more convenient to move the portal pier steel cap beam to the top of the guide groove 1, and on the other hand, it can reduce the situation where the portal pier steel cap beam falls off from the top of the guide groove 1 due to the backward sliding after entering the top of the guide groove 1. Through the above structure, by setting the guide plate 4, the portal pier steel cap beam can be guided and limited, so that the portal pier steel cap beam can be turned over more conveniently.

[0026] like Figure 4 As shown, a plurality of guide grooves 5 are provided at the bottom of the guide groove 1; the plurality of guide grooves 5 are located in the middle of two adjacent leakage holes 31, and are connected to the plurality of leakage holes 31. During operation, the waste lubricating liquid will enter the interior of the collecting box 32 through the leakage holes 31. At this time, by providing the guide groove 5 in the middle of two adjacent leakage holes 31, the waste lubricating liquid can flow along the guide of the guide groove 5, thereby reducing the turbulence of the waste lubricating liquid, which makes it difficult for the waste lubricating liquid to enter the interior of the collecting box 32 for collection. Through the above structure, the waste lubricating liquid can flow into the interior of the collecting box 32 more accurately to complete the collection of the waste lubricating liquid.

[0027] like Figure 3 and Figure 4 As shown, a filter plate 6 is fixedly connected to the middle of the plurality of leakage holes 31; the radius of the filter plate 6 is the same as that of the leakage hole 31. When working, by setting the filter plate 6, it is possible to reduce the dust and impurities inside the guide groove 1 from entering the interior of the collecting box 32 through the leakage hole 31, which would cause excessive dust or impurities inside the collecting box 32, thereby affecting the collection of the lubricating liquid. Through the above structure, the lubricating liquid entering the collecting box 32 can be preliminarily filtered, thereby reducing the impurities carried by the waste lubricating liquid entering the collecting box 32, making the subsequent treatment of the waste lubricating liquid more convenient.

[0028] like Figure 1 As shown, the width of the guide groove 1 can be customized and is the same as the width of the steel cap beam. Through the above settings, the guide groove 1 can use more portal pier steel cap beams, thereby increasing the practicality of the guide groove 1 to a certain extent.

[0029] During operation, multiple pulleys 15 are slid, and as the multiple pulleys 15 slide, multiple rotating rollers 14 are driven to slide inside the slide groove 13. At this time, the multiple pulleys 15 are slid to the end of the guide groove 1, and then a crane or other device is used to place the portal pier steel cap beam to be installed at the end of the guide groove 1. At this time, as the portal pier steel cap beam is placed on the top of the guide groove 1, the portal pier steel cap beam will contact the multiple pulleys 15. At this time, the multiple pulleys 15 will place the portal pier steel cap beam on top of the guide groove 1. At the same time, the portal pier steel cap beam will slide as the multiple pulleys 15 slide. At this time, by sliding multiple pulleys 15, the portal pier steel cap beam can be driven to slide along the contour of the guide groove 1. At this time, the portal pier steel cap beam slides along the contour of the guide groove 1 until Slide to the position of the discharge hole 16, it can become an upright state, and then slide out from the middle of the discharge hole 16. When the portal pier steel cap beam slides above the guide groove 1, multiple limit rods 17 can limit the portal pier steel cap beam, reducing the portal pier steel cap beam from tipping over during the sliding process. Multiple pulleys 15 and rotating rollers 14 slide inside the grooves 12 and the slide grooves 13 to drive the portal pier steel cap beam to turn over. As time goes by, there will be certain wear between the pulleys 15 and the grooves 12 and the slide grooves 13 and the rotating rollers 14. When the wear is more serious, it will cause the pulleys 15 to be difficult to slide inside the grooves 12, thereby making it difficult to drive the portal pier steel cap beam to turn over. At this time, lubricating fluid is filled into the water tank 2 and then started. The water pump placed inside the water tank 2, as the water pump is started, the lubricating liquid inside the water tank 2 will fill the inside of the water pipe 21. At this time, the lubricating liquid flows along the contour of the water pipe 21 until it is sprayed out from the end of the water pipe 21. At this time, the end of the water pipe 21 enters the inside of the groove 12 through the through hole 22, so the lubricating liquid sprayed from the water pipe 21 will be sprayed into the inside of the groove 12. Spraying the lubricating liquid on the inside of the groove 12 through the water pipe 21 can lubricate the pulley 15 in time, thereby reducing the wear between the pulley 15 and the groove 12. At this time, the excess lubricating liquid sprayed by the water pipe 21 will accumulate inside the groove 12, causing the lubricating liquid to absorb dust. At this time, a plurality of liquid outlet holes 3 are opened on the inner side wall of the guide groove 1, and then a liquid outlet hole 3 is opened at the bottom of the guide groove 1. A plurality of leakage holes 31 are provided, so that the lubricating liquid can flow along the liquid outlet hole 3 to the inside of the guide groove 1, and then flow out from the leakage hole 31. The flowing lubricating liquid will directly fall into the inside of the collecting box 32. By providing the guide plate 4, a crane or other equipment can be used to place the portal pier steel cap beam on the top of the guide groove 1 through the guide plate 4. At the same time, by setting the guide plate 4 to be tilted upward, on the one hand, it can be more convenient to place the portal pier steel cap beam on the top of the guide groove 1. On the other hand, it can reduce the situation where the portal pier steel cap beam falls off from the top of the guide groove 1 due to the backward sliding after entering the top of the guide groove 1. The waste lubricating liquid will enter the inside of the collecting box 32 through the leakage hole 31. At this time, a guide groove 5 is opened in the middle of two adjacent leakage holes 31.The waste lubricating liquid can flow along the guide groove 5, reducing the turbulence of the waste lubricating liquid, which makes it difficult for the waste lubricating liquid to enter the collection box 32 for collection. By setting the filter plate 6, the dust and impurities in the guide groove 1 can be reduced from entering the collection box 32 through the leakage hole 31, resulting in excessive dust or impurities in the collection box 32, thereby affecting the collection of the lubricating liquid.
