DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] The orientations mentioned in this specification are based on the orientations of the horizontal mold for a wind power concrete tower of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0031] Embodiment 1:

[0032] like Figures 1 to 5 As shown, a horizontal mold for a wind power concrete tower includes a bottom mold 1, a top side mold 16, a bottom side mold 17, two side end molds 15 and two side cover plate assemblies, the cover plate assembly includes a rear section cover plate 2 whose outer end is hinged to the bottom mold 1 and a front section cover plate 3 whose outer end is hinged to the inner end of the rear section cover plate 2, a plurality of front section cover plate assisting mechanisms are installed at the hinge of the front section cover plate 3 and the rear section cover plate 2, and a plurality of rear section cover plate assisting mechanisms are provided at the hinge of the rear section cover plate 2 and the bottom mold 1.

[0033] The cover plate assembly includes a front section cover plate 3 and a rear section cover plate 2. Two actions are required to open and close the cover plate, but the opening and closing size is small and more labor-saving. The front section cover plate assisting mechanism can assist the opening and closing of the front section cover plate 3, and the rear section cover plate assisting mechanism can assist the opening and closing of the rear section cover plate 2, making the opening and closing of the mold more labor-saving and improving work efficiency.

[0034] The cover plate assemblies on both sides are symmetrically arranged, and an opening for injecting concrete is formed between the front section cover plates 3 of the two cover plate assemblies.

[0035] Among them, the bottom mold 1 and the side mold are equipped with opening and closing bolts 20, fastening bolts 21 and adjusting bolts 22. The opening and closing bolts 20 and the fastening bolts 21 are positive and negative thread bolts, the bottom mold 1 is provided with negative thread nuts 24 corresponding to the positive and negative thread bolts, and the side mold is provided with positive thread nuts 25 corresponding to the positive and negative thread bolts. The adjusting bolt 22 is screwed on the side mold, the end of the adjusting bolt 22 is a convex spherical surface, and the bottom mold 1 is provided with a concave spherical surface adapted to the convex spherical surface.

[0036] Wherein, a plurality of supports 10 are installed at the bottom of both sides of the bottom mold 1, and the supports 10 are leveling supports.

[0037] When the front section cover plate 3 is turned over to the rear section cover plate 2, the top of the front section cover plate 3 rests on the top of the rear section cover plate 2. By adopting the above method, the space occupied by the cover plate after opening can be further reduced. After the front section cover plate 3 and the rear section cover plate 2 are closed, they are locked to the side mold by the locking bolts 4 on both sides.

[0038] Furthermore, the front section cover plate 3 and the rear section cover plate 2 are hinged by the front hinge shaft 7, and the front section cover plate assist mechanism is a front torsion spring 8 installed on the front hinge shaft 7, and the front torsion spring 8 is in a free state when the front section cover plate 3 is vertical. When the front section cover plate 3 is opened, in the process of swinging upward to the vertical state, the front section cover plate 3 is pulled up by the torsion of the front section cover plate 3, and in the process of the front section cover plate 3 continuing to swing to the state of abutting against the rear section cover plate 2, although the front section cover plate 3 is subjected to the torsion of pulling up, it is also easy to move under the action of its own gravity. When the front section cover plate 3 is closed, in the process of swinging upward to the vertical state, the front section cover plate 3 is pulled up by the torsion of the front section cover plate 3, and in the process of the front section cover plate 3 continuing to swing to the closed state, although the front section cover plate 3 is subjected to the torsion of pulling up, it is also easy to move under the action of its own gravity.

[0039] Among them, two groups of first connecting plates are fixedly connected to the front section cover plate 3, and two groups of second connecting plates are fixedly connected to the rear section cover plate 2. The two ends of the front hinge shaft 7 are rotatably mounted on the first connecting plates and the second connecting plates at the two ends. One torsion bar of the front torsion spring 8 is mounted on the rear section cover plate 2, and the other torsion bar of the torsion spring is mounted on the front section cover plate 3. The opening and closing of the front section cover plate 3 is assisted by the forward and reverse torque of the front torsion spring 8.

[0040] Furthermore, the rear section cover plate 2 and the bottom mold 1 are hinged by the rear hinge shaft 9, and the rear hinge shaft 9 is set to two. The rear section cover plate assist mechanism is the first rear torsion spring 32 and the second rear torsion spring 33 respectively installed on both sides of the rear hinge shaft 9, and the torsion of the first rear torsion spring 32 and the second rear torsion spring 33 is different. When opening the rear section cover plate 2, the torsion of the rear torsion spring can offset the gravity of the cover plate, which is convenient for opening the rear section cover plate 2. Through the initial angle of the torsion spring installation, only the first rear torsion spring 32 is stressed within the range of about 10 degrees of the closing swing of the cover plate, avoiding excessive torque that needs to be overcome when the rear section cover plate 2 is just beginning to close downward, so that the cover plate can be easily operated by two people. After the rear section cover plate 2 swings down more than 10 degrees, the first rear torsion spring 32 and the second rear torsion spring 33 are both stressed, but it is easy to close under the action of gravity.

[0041] Among them, hinged plates 11 are symmetrically installed on both sides of the rear section cover plate 2. The hinged plates 11 are hinged to the mold legs 12 through the rear hinge shaft 9. One torsion rod of the rear torsion spring is connected to the legs, and the other torsion rod of the rear torsion spring is connected to the hinged plates 11.

[0042] Furthermore, hook rings 13 are fixedly connected to both sides of the front section cover plate 3, and mounting frames 19 are fixedly connected to both sides of the rear section cover plate 2, and hooks 14 are hingedly connected to the mounting frames 19. One end of the tension spring 18 is connected to the hook 14, and the other end of the tension spring 18 is connected to the mounting frame 19. The tension spring 18 drives the hook 14 to be in a state perpendicular to the rear section cover plate 2. When the front section cover plate 3 is locked to the rear section cover plate 2, the hook 14 is manually swung down. After the front section cover plate 3 is in place, the hook 14 is released, and the hook 14 is reset under the action of the tension spring 18 and the hook-shaped portion is inserted into the hook ring 13.

[0043] Furthermore, a locking mechanism is installed on the bottom mold 1 to lock the rear section cover plate 2 when the rear section cover plate 2 is opened to a vertical state. The locking mechanism can also adopt a structure of a hook 14 and a hook ring 13.

[0044] Further, a platform 23 is installed on the outer side of the bottom mold 1. The arrangement of the platform 23 enables a worker to stand on the platform 23 to open and close the cover plate assembly, which is convenient for opening and closing the mold.

[0045] Further, a plurality of buffers 5 are installed on the rear section cover plate 2, and a plurality of buffer plates 6 are installed on the front section cover plate 3 to abut against the buffers 5 after the front section cover plate 3 is turned over. The buffer 5 uses a polyurethane buffer 5.
