[0007] Preferably, the inner side of the square tube is fixedly connected with fixing plates which are evenly spaced and movably sleeved on the outer side of the drive shaft. Beneficial effects

[0008] 1. The concrete component turning machine can drive the turning frame located above the square tube to move along the axial direction of the fixed rod through the drive of the second hydraulic motor, and then gradually move the turning frame to the top of the concrete component. The first hydraulic motor can drive the square tube to rotate around the axial direction of the drive shaft and simultaneously drive the two turning frames to rotate around the axial direction of the drive shaft, thereby realizing the turning operation of the concrete component. During this process, the transmission cooperation of the worm gear and the worm enables the two turning frames to be self-locking during the rotation process, and its stability is relatively high.

[0009] 2. The concrete component turning machine can detect the concrete component placed on the turning frame through the first photoelectric sensor while controlling the third hydraulic motor to be unable to drive. Then, the turning frame located above the square tube can be driven to move to the top of the concrete component by starting the second hydraulic motor. During this process, the first hydraulic motor can be started synchronously to drive the two turning frames to turn synchronously. This structure makes it possible for the two turning frames to turn simultaneously without alternating operation, thereby improving the turning efficiency of the turning equipment.

DETAILED DESCRIPTION

[0018] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0019] The drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0020] See also Figure 1-6 , a concrete component turning machine includes a first fixed frame 1 and a second fixed frame 2, a cross bar 3 fixedly connected between the first fixed frame 1 and the second fixed frame 2, and a support frame 4 fixedly installed on the cross bar 3, the support frame 4 can limit the turning frame 11 and make it not easy to bend when the turning frame 11 is subjected to the gravity of the concrete component, the first fixed frame 1 and the second fixed frame 2 are connected to the driving shaft 5 for rotation together, the outside of the second fixed frame 2 is fixedly installed with a first driving mechanism 6, the outside of both ends of the driving shaft 5 are fixedly sleeved with a fixed block 7, the outside of the fixed block 7 is fixedly sleeved with a square tube 8, the top and bottom of the square tube 8 are provided with fixed sleeves 9 distributed at equal intervals, the inside of the fixed sleeve 9 is movably sleeved with a fixed rod 10, the outside of the fixed rod 10 is fixedly connected to the turning frame 11, and the inside of the square tube 8 is fixedly sleeved with a second driving mechanism 12.

[0021] Among them, the second driving mechanism 12 includes a second hydraulic motor 121 fixedly mounted on the middle part of the top of the square tube 8, a third hydraulic motor 122 fixedly mounted on the middle part of the bottom of the square tube 8, and a rack 123 fixedly installed on the outside of the turning frame 11. The outsides of the output shafts of the second hydraulic motor 121 and the third hydraulic motor 122 are fixedly mounted with a third gear 124 that meshes with the rack 123. The drive of the second hydraulic motor 121 can drive the third gear 124 to rotate, and at the same time, the rack 123 can drive the turning frame 11 located above the square tube 8 to move axially along the fixed rod 10, thereby moving the turning frame 11 to the top of the concrete component, so that the concrete component can be stably limited by the two turning frames 11 during the turning operation.

[0022] Among them, the inner side of the support frame 4 is fixedly installed with a first photoelectric sensor 13 and a second photoelectric sensor 14 which are electrically connected to the third hydraulic motor 122 and the second hydraulic motor 121 respectively. The first photoelectric sensor 13 can detect the concrete component and control the drive of the third hydraulic motor 122 at the same time. When the first photoelectric sensor 13 detects the concrete component, the third hydraulic motor 122 cannot be driven, and the second photoelectric sensor 14 can detect the concrete component and control the drive of the second hydraulic motor 121 at the same time. When the second photoelectric sensor 14 does not detect the concrete component, the second hydraulic motor 121 can be driven.

[0023] Among them, the first driving mechanism 6 includes a first hydraulic motor 61 fixedly installed on the outside of the second fixed frame 2, a first support 62 and a second support 63, a rotating shaft 64 rotatably connected to the inside of the second fixed frame 2, and a first gear 65 fixedly sleeved on the outside of one end of the driving shaft 5. The outer side of the rotating shaft 64 is fixedly sleeved with a second gear 66 and a worm gear 67. The first gear 65 and the second gear 66 are meshed with each other for transmission. A worm 68 meshing with the outer edge of the worm gear 67 is rotatably connected between the first support 62 and the second support 63. The outer side of one end of the worm 68 extending outside the second support 63 is fixedly sleeved with the output shaft of the first hydraulic motor 61 through a shaft sleeve 69. The drive of the first hydraulic motor 61 can drive the worm 68 to rotate and at the same time drive the rotating shaft 64 to rotate synchronously through the worm gear 67. Then, through the cooperation of the first gear 65 and the second gear 66, the square tube 8 and the turning frame 11 located above the square tube 8 are driven to rotate around the axial direction of the driving shaft 5, thereby realizing the turning operation of the concrete component.

[0024] Among them, the inner side of the square tube 8 is fixedly connected with a fixing plate 15 that is evenly spaced and movably sleeved on the outer side of the drive shaft 5. The fixing plate 15 can enhance the structural strength of the square tube 8, so that the square tube 8 is not easily bent and deformed when subjected to external force.

[0025] When the turning machine is in use, the concrete component is hoisted to the surface of the turning frame 11 located below the square tube 8. At this time, the first photoelectric sensor 13 detects that the third hydraulic motor 122 of the concrete component cannot be driven, and the second hydraulic motor 121 and the first hydraulic motor 61 are started. The third gear 124 is driven by the second hydraulic motor 121 to rotate, and at the same time, the turning frame 11 located above the square tube 8 is driven to gradually move along the axial direction of the fixed rod 10 through the rack 123. The worm 68 is driven by the first hydraulic motor 61 to rotate, and the rotating shaft 64 is driven to rotate through the worm gear 67. When the rotating shaft 64 rotates, the driving shaft 5 is driven to rotate through the cooperation of the first gear 65 and the second gear 66. When the driving shaft 5 rotates, it drives the square tube 8 and the two turning frames. The frame 11 rotates about the axial direction of the drive shaft 5. When the rotation angle of the turning frame 11 is less than 80 degrees, the turning frame 11 located above is completely moved to the top of the concrete member under the drive of the second hydraulic motor 121. The concrete member is turned from above the first photoelectric sensor 13 to above the second photoelectric sensor 14 through the continuous rotation of the first hydraulic motor 61. When the second photoelectric sensor 14 detects the concrete member, the second hydraulic motor 121 cannot be driven, and the third hydraulic motor 122 is started to drive the turning frame 11 located above the concrete member to move while removing the turning frame 11 from above the concrete member, completing the turning operation of the concrete member.
