Technical Field
[0001] The utility model relates to the technical field of penstock hoisting, in particular to a penstock semicircular tile turning device. Background Art
[0002] Penstock is a steel pipeline used to transport water at extremely high pressure. The production process of large-diameter penstock used in hydropower stations is basically as follows: the steel plate is rolled into semicircular tiles by a plate rolling machine, and then 2-3 semicircular tiles are spliced into a penstock on a circular platform. In the process of splicing the semicircular tiles into penstocks, some of the semicircular tiles need to be turned over before they can be spliced smoothly.
[0003] The current semi-circular tile turning device is turned over by directly lifting it through a gantry crane and a hook. The semi-circular tile cannot be turned over in the air. Since the turning over process is unstable, sleepers or sand pits are usually required to assist the turning over of the semi-circular tiles. The turning over process of the semi-circular tiles has requirements on the processing environment, which leads to limitations in the turning over of the semi-circular tiles. Utility Model Content
[0004] The utility model provides a penstock semicircular tile turning device, which improves the stability of the semicircular tile turning process and does not need to be equipped with too many auxiliary equipment.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0010] Preferably, the number of the first clamps and the number of the second clamps are both two, the two first clamps are clamped at the left end of the semicircular tile, and the two second clamps are clamped at the right end of the semicircular tile.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0017] like Figure 1 , Figure 2 As shown, a semicircular tile turning device for a pressure steel pipe includes a first turning component; the first turning component includes a first hook 7 and a second hook 8, and also includes a first clamp 1 and a second clamp 2 clamped at both ends of the semicircular tile 11, two support members are installed on the first clamp 1, and there is a gap between the two support members; one end of the first steel wire rope 9 is fixedly connected to the front side of the second clamp 2, and the other end of the first steel wire rope 9 passes through the gap between the two support members and is connected to the first hook 7; a connecting column is also provided on the front side of the second clamp, one end of the second steel wire rope 10 is connected to the second hook 8, and the other end of the second steel wire rope 10 is connected to the connecting column so that there is a distance between the connection point of the second steel wire rope 10 and the side of the second clamp 2.
[0018] The penstock itself is a pipe used to transport extremely high water pressure and water flow, with a large diameter and a heavy weight. The large-diameter penstock used in a hydropower station under specific circumstances has a larger diameter and a larger weight. Therefore, the semicircular tile 11, which is the splicing material of the penstock, is unstable during the turning process and needs to be equipped with sleepers or sand pits to assist the turning of the semicircular tile 11.
[0019] The improvement of the utility model is that the semicircular tile 11 is turned over stably in the air without the need to equip sleepers or configure sand pits for auxiliary work. The first clamp 1 and the second clamp 2 are respectively clamped and fixed on the two ends of the semicircular tile 11 in the axial direction, the first steel wire rope 9 passes through the gap between the two supports and is connected to the first hook 7, and the second steel wire rope 10 is connected to the second hook 8 through the connecting column, and the first hook 7 and the second hook 8 are controlled to rise to lift the semicircular tile 11 into the air, so that the semicircular tile 11 is in a suspended state. In the suspended state, the first hook 7 rises slowly and the second hook 8 falls slowly, so that the first clamp 1 and the second clamp 2 have a height difference, and move toward the direction of the second hook 8 during the slow rise of the first hook 7, and move toward the direction of the first hook 7 during the slow fall of the second hook 8. The semicircular tile 11 changes from a horizontal state to a vertical state, and then the first hook 7 is lowered and the second hook 8 is raised, so that the semicircular tile 11 is turned over to a horizontal state, and the stable turning over of the semicircular tile 11 in the air is completed. The second steel wire rope 10 is connected to the second hook 8 through the connecting column of the second clamp 2. The connecting column has a thickness so that there is a distance between the connection point of the second steel wire rope 10 and the side of the second clamp 2, so that the second steel wire rope 10 and the first steel wire rope 9 are staggered, so that the first hook 7 and the second hook 8 can smoothly complete the position exchange, and the problem of collision between the first steel wire rope 9 and the second steel wire rope 10 will not occur during the turning over of the semicircular tile 11. The first steel wire rope 9 passes through the gap between the two supporting members. Before and after the semicircular tile 11 turns over, the two sides of the first steel wire rope 9 are restricted and supported by the two supporting members respectively. The semicircular tile 11 itself is not a column. The axial direction of the semicircular tile 11 mentioned above refers to the axial direction of the pressure steel pipe after the semicircular tiles 11 are spliced.
[0020] Preferably, the first clamp 1 is an F-type clamp, the right end of which is provided with a first bayonet, the F-type clamp includes a protrusion located at the upper end, and the two support members are mounted on the protrusion; the second clamp 2 is a U-type clamp, the left end of which is provided with a second bayonet. The first clamp 1 is an F-type clamp, and has a protrusion, which is located outside the top of the F-type clamp and is used to install the support member, so that the distance between the force points of the first steel wire rope 9 can be increased, and the semicircular tile 11 can be turned over more stably.
[0021] Preferably, the support member is a first grooved roller 3, and two first grooved rollers 3 are installed at the upper end and the lower end of the protrusion. The support member is a first grooved roller 3, and the first steel wire rope 9 is wound in the groove of the first grooved roller 3, providing more stable restriction and support for the first steel wire rope 9.
[0022] Further, the connecting column includes a movable rod 6, a second grooved roller 4 and a third roller 5; the second grooved roller 4 is installed at the upper end of the movable rod 6, and the third roller 5 is installed at the lower end of the movable rod 6; one end of the second steel wire rope 10 is connected to the second hook 8, and the other end of the second steel wire rope 10 bypasses the second grooved roller 4 and is connected back to the second hook 8, and the second grooved roller 4 at the lower end of the movable rod 6 is rotatably connected to the first clamp 1. The supporting member includes the movable rod 6, the second grooved roller 4 and the third roller 5, and the third roller 5 has a certain thickness, and after connection, the first steel wire rope 9 and the second steel wire rope 10 are misaligned. The second steel wire rope 10 passes around the second grooved roller 4 and is connected back to the second hook 8 to form a double-strand second steel wire rope 10. The double-strand second steel wire rope 10 has a greater supporting strength. During the turning over of the semicircular tile 11, the second hook 8 needs to be lowered to form the main support for the semicircular tile 11. The semicircular tile 11 is heavy, and the double-strand second steel wire rope 10 is more suitable for the turning over process.
[0023] Preferably, a second turning assembly having the same structure as the first turning assembly is also included; the two first clamps 1 are clamped at the left end of the semicircular tile 11, and the two second clamps 2 are clamped at the right end of the semicircular tile 11. Two first clamps 1 and two second clamps 2 are provided, and the corresponding first hooks 7, second hooks 8, first steel wire ropes 9 and second steel wire ropes 10 are all two, forming two sets of turning devices, which are symmetrically installed on both sides of the semicircular tile 11, respectively, to provide more force points and improve the stability of the turning process.
