[0037] like Figure 1-Figure 11 As shown, the front and rear sides of the movable frame 20 are slidably connected in the two long holes Ⅰ8 respectively.

[0038] like Figure 1-Figure 11 As shown, a raised frame 27 is fixedly connected to the middle of the movable frame 20 , a fixed end of an electric push rod II 28 is fixedly connected to the middle of the raised frame 27 , and a movable end of the electric push rod II 28 is fixedly connected to the middle of the upper side of the positioning frame 24 .

[0039] like Figure 1-Figure 11 As shown, a support frame 9 is fixedly connected to the top left side of the measuring frame 1, a limit strip 10 is fixedly connected to the right bottom side of the support frame 9, a fixed end of an electric push rod Ⅰ19 is fixedly connected to the middle of the upper side of a lifting frame 15, a cross bar 16 is fixedly connected to the bottom of the lifting frame 15, a pressing wheel 17 is rotatably connected to the middle of the cross bar 16, the lower surface of the pressing wheel 17 contacts the upper surface of the measuring ruler 13, a long hole Ⅱ18 is respectively provided on the front and rear sides of the lifting frame 15, and the front and rear sides of the limit strip 10 are slidably connected in the two long holes Ⅱ18.

[0040] like Figure 1-Figure 11 As shown, each of the sliding seats 21 is fixedly connected to a positioning seat 22 at the bottom, each positioning seat 22 is fixedly connected to a fixed end of a hydraulic cylinder 35 at the middle, and a vertical plate 29 is fixedly connected to the movable ends of the two hydraulic cylinders 35. An open groove 30 is provided on the upper side of the two vertical plates 29, and the two open grooves 30 are slidably connected to the front and rear sides of the moving frame 20, respectively. A plurality of scraper plates 31 are evenly fixedly connected to the adjacent sides of the two vertical plates 29;

[0041] The two vertical plates 29 are arranged in mirror image.

[0042] like Figure 1-Figure 11 As shown, each of the vertical plates 29 is fixedly connected to a liquid storage barrel 32 on its outer side, and each of the liquid storage barrels 32 is fixedly connected to a side vertical pipe 33 on the right side of its bottom, and each of the side vertical pipes 33 is evenly fixed and connected to a plurality of nozzles 34 arranged toward the inner side of the measuring frame 1.

[0043] In order to improve the efficiency of automatic length measurement of precast concrete components, when in use, the precast concrete component is placed inside the measuring frame 1, and the rotating rollers 6 on the multiple support rods 5 are rotated so that the precast concrete component can slide into the measuring frame 1 in contact with the multiple rotating rollers 6, thereby reducing the fatigue of placing the bulky precast concrete component. Through the multiple rotating rollers 6, one side of the precast concrete component is placed on the left side of the inside of the measuring frame 1, and then the fixed wheel 14 moves to the right side of the measuring frame 1 and stretches out the measuring ruler 13, and then the length of the precast concrete component is measured by the extended length of the measuring ruler 13. It is simple, reliable, convenient and effective, and is convenient to improve the efficiency of automatic length measurement of precast concrete components.

[0044] In order to facilitate the automated length measurement of larger precast concrete components, when in use, the driving motor 7 causes the lead screw 4 to rotate. When the lead screw 4 rotates, the sliding seat 21 threadedly connected thereto moves laterally, and the mobile frame 20 moves synchronously with the lateral movement of the two sliding seats 21, driving the pulling rod 26 located in the middle of the mobile frame 20 to pull the fixed wheel 14 horizontally, so that the measuring ruler 13 can be horizontally expanded, thereby facilitating the automated length measurement of larger precast concrete components.

[0045] In order to further improve the accuracy of measuring the length of precast concrete components of different thicknesses, the measuring ruler 13 can be placed on the upper surface of the precast concrete component for measurement to prevent measurement deviation caused by suspended measurement. When in use, after the pull rod 26 follows the lateral movement of the mobile frame 20 so that the fixed wheel 14 opens the measuring ruler 13, the electric push rod II 28 is driven so that the positioning frame 24 located on the movable end of the electric push rod II 28 drives the pull rod 26 to move downward so that one end of the measuring ruler 13 located on the fixed wheel 14 is placed on the precast concrete components of different thicknesses. At the same time, the electric push rod Ⅰ19 is driven so that the lifting frame 15 located on the movable end of the electric push rod Ⅰ19 drives the pressing wheel 17 on the cross bar 16 to press the left stretched position of the measuring ruler 13 downward, so that the left side of the measuring ruler 13 can be simultaneously attached to the left side of the precast concrete component to fit the length of the precast concrete component, further improving the work of accurately measuring the length of precast concrete components of different thicknesses, and the measuring ruler 13 can be attached to the upper surface of the precast concrete component for measurement to prevent measurement deviation caused by suspended measurement.

[0046] When the moving frame 20 moves laterally, in order to facilitate the scraping of surface protrusions and burrs on the front and rear surfaces of the precast concrete components, when in use, the hydraulic cylinders 35 on both sides are driven to make the vertical plates 29 located on the movable ends of the two hydraulic cylinders 35 move on the front and rear sides of the moving frame 20 by relying on the open grooves 30, so that the scraper plates 31 located on the adjacent side surfaces of the two hydraulic cylinders 35 are attached to the front and rear surfaces of the precast concrete components, and then the scraper plates 31 follow the moving frame 20 above it to move laterally to scrape off the burrs and protrusions on the front and rear surfaces of the precast concrete components, thereby improving the surface integrity of the precast concrete components and making them more beautiful. When the scraper plates 31 scrape off the burrs and protrusions, in order to facilitate the dust reduction work generated during the scraping, the water located in the two liquid storage barrels 32 is sprayed out through the nozzles 34 on each side vertical pipe 33, thereby preventing the dust caused by the scraping work from affecting the vision of the staff, and the surface of the precast concrete components can be moistened to prevent cracking caused by long-term exposure to the sun.
