Technical Field
[0001] The utility model relates to the technical field of concrete forming moulds, in particular to a folding cover plate used for a concrete forming mould. Background Art
[0002] At present, the diameter of domestic subways and tunnels is constantly increasing, and the wind power tower is constantly rising, so the size of the wind power tower mold is also increasing. The current wind power tower mold uses an integral flip cover, which needs to be opened when demoulding. However, the integral flip cover is too high when opened, which limits the passage of the mold on the assembly line, and the size is too large, so it is more difficult to open and close the cover. Utility Model Content
[0003] The utility model aims to provide a folding cover for a concrete forming mold, aiming to solve the technical problems in the prior art that the integral flip cover is too high when opened, the passage of the mold on the assembly line is restricted, and the size is too large, making the opening and closing of the cover difficult.
[0004] In order to solve the above technical problems, the technical solution of the utility model is:
[0005] A folding cover plate for a concrete forming mould comprises a rear section cover plate whose outer end is hinged on the mould and a front section cover plate whose outer end is hinged on the inner end of the rear section cover plate.
[0006] By adopting the above structure, the cover plate is divided into two parts, namely the front cover plate and the rear cover plate. When opening the cover plate, the front cover plate is flipped upwards and then the rear cover plate is flipped upwards. The height of the cover plate is lowered when it is opened, and the mold is convenient to pass on the assembly line. Two actions are required to open and close the cover plate, but the opening and closing size is small and it is more labor-saving.
[0007] Preferably, the front section cover plate can be turned upwards to the rear section cover plate. The front section cover plate can be turned upwards to the rear section cover plate, which can reduce the space occupied after the cover plate is opened.
[0008] Preferably, when the front section cover plate is turned over to the rear section cover plate, the top of the front section cover plate rests on the top of the rear section cover plate. By adopting the above method, the space occupied by the cover plate after opening can be further reduced.
[0009] Preferably, a plurality of buffers are installed on the rear section cover plate. The arrangement of the buffers can provide buffering when the front section cover plate is turned over to the top of the rear section cover plate, thereby avoiding vibration of the mold and damage to the cover plate.
[0010] Preferably, a plurality of buffer plates are installed on the front section cover plate, which abut against the buffer after the front section cover plate is turned over. The buffer plates cooperate with the buffer to buffer the front section cover plate when it is turned over in place, thereby increasing the service life of the cover plate.
[0011] Preferably, a plurality of front section cover plate assisting mechanisms are installed at the hinged joints of the front section cover plate and the rear section cover plate. The front section cover plate assisting mechanisms can assist the opening and closing of the front section cover plate, making the opening and closing of the front section cover plate more labor-saving.
[0012] Preferably, the front section cover plate and the rear section cover plate are hinged by a front hinge shaft, and the front section cover plate assist mechanism is a front torsion spring installed on the front hinge shaft, and the front torsion spring is in a free state when the front section cover plate is vertical. When the front section cover plate is opened, during the process of swinging upward to a vertical state, the front section cover plate is pulled upward by the torsion of the front section cover plate, and during the process of the front section cover plate continuing to swing to a state against the rear section cover plate, although the front section cover plate is subjected to the torsion of pulling upward, it is also easy to move under the action of its own gravity. When the front section cover plate is closed, during the process of swinging upward to a vertical state, the front section cover plate is pulled upward by the torsion of the front section cover plate, and during the process of the front section cover plate continuing to swing to a closed state, although the front section cover plate is subjected to the torsion of pulling upward, it is also easy to move under the action of its own gravity.
[0013] Preferably, a plurality of rear section cover plate assisting mechanisms are provided at the hinged joint between the rear section cover plate and the mold. The rear section cover plate assisting mechanisms can offset the gravity of the rear section cover plate itself when the rear section cover plate is opened and closed, making the opening of the rear section cover plate more labor-saving.
[0014] Preferably, the invention further comprises a locking mechanism for locking the front section cover plate when the front section cover plate is turned over to the rear section cover plate. The setting of the locking mechanism enables the front section cover plate to be locked to the rear section cover plate when the front section cover plate is turned over to the rear section cover plate.
[0015] Preferably, the locking mechanism comprises a hook ring mounted on the front section cover plate and a hook hinged on the rear section cover plate. When the front section cover plate is turned over to the rear section cover plate, the hook swings to insert into the hook ring, locking the front section cover plate to the rear section cover plate.
[0016] After adopting the above technical solution, the beneficial effects of the utility model are:
[0017] The utility model divides the cover plate into two parts, a front section cover plate and a rear section cover plate. When opening the cover plate, the front section cover plate is flipped upwards, and then the rear section cover plate is flipped upwards. The height of the cover plate is lowered when it is opened, and the mold is convenient to pass on the assembly line. Two actions are required to open and close the cover plate, but the opening and closing size is small and labor-saving. The front section cover plate can be flipped upwards to the rear section cover plate, which can reduce the space occupied by the cover plate after it is opened. The setting of the buffer can buffer when the front section cover plate is flipped to the top of the rear section cover plate, avoiding vibration of the mold and damage to the cover plate.

DETAILED DESCRIPTION
[0024] The utility model is further described below in conjunction with the accompanying drawings.
[0025] The orientations involved in this specification are based on the orientations of the folding cover plate for a concrete forming mold of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.
[0026] like Figures 1 to 5 As shown, a folding cover plate for a concrete forming mold comprises a rear section cover plate 2 whose outer end is hinged to a 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 .
[0027] The utility model divides the cover plate into two parts, a front cover plate 3 and a rear cover plate 2. When opening the cover plate, the front cover plate 3 is flipped upward, and then the rear cover plate 2 is flipped upward. The height of the cover plate is lowered when it is opened, and the mold 1 is convenient to pass on the assembly line. Two actions are required to open and close the cover plate, but the opening and closing size is small, which is more labor-saving.
[0028] There are two folding cover plates, which are symmetrical to each other, and an opening for injecting concrete is formed between the front section cover plates 3 of the two folding cover plates.
[0029] Among them, the front section cover plate 3 can be turned upward to the rear section cover plate 2. The front section cover plate 3 can be turned upward to the rear section cover plate 2, which can reduce the space occupied after the cover plate is opened.
[0030] Further, when the front section cover plate 3 is turned over onto 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 manner, the space occupied by the cover plate after opening can be further reduced.
[0031] After the front section cover plate 3 and the rear section cover plate 2 are closed, they are locked to the mold 1 by the locking bolts 4 on both sides.
[0032] As a preferred example of the utility model, a plurality of buffers 5 are installed on the rear section cover plate 2. The setting of the buffer 5 can buffer the front section cover plate 3 when it is turned over to the top of the rear section cover plate 2, avoid vibration of the mold 1, and avoid damage to the cover plate.
[0033] The buffer 5 is a polyurethane buffer 5 installed on the rear section cover plate 2 .
[0034] Further, a plurality of buffer plates 6 are mounted on the front section cover plate 3, which abut against the buffer 5 after the front section cover plate 3 is turned over. The buffer plates 6 cooperate with the buffer 5 to buffer the front section cover plate 3 when it is turned over in place, thereby improving the service life of the cover plate.
[0035] As a preferred example of this embodiment, 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. The front section cover plate assisting mechanisms can assist the opening and closing of the front section cover plate 3, making the opening and closing of the front section cover plate 3 more labor-saving.
[0036] Among them, 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. There are two front hinge shafts 7, and two groups of first connecting plates 15 are fixedly connected to the front section cover plate 3, and two groups of second connecting plates 16 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 15 and the second connecting plates 16 at the two ends respectively. One torsion bar of the front torsion spring 8 is installed on the rear section cover plate 2, and the other torsion bar of the torsion spring is installed on the front section cover plate 3. The opening and closing of the front section cover plate 3 is assisted by the torque of the front torsion spring 8 in the positive and negative directions. When the front section cover plate 3 is opened, during the process of swinging upward to the vertical state, the front section cover plate 3 is pulled upward by the torque of the front section cover plate 3. During 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 torque of pulling upward, it is also easy to move under the action of its own gravity. When the front section cover plate 3 is closed, during the process of swinging upward to the vertical state, the front section cover plate 3 is pulled upward by the torque of the front section cover plate 3. During 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 torque of pulling upward, it is also easy to move under the action of its own gravity.
[0037] As a preferred example of this embodiment, a plurality of rear section cover plate assist mechanisms are provided at the hinge of the rear section cover plate 2 and the mold 1. The rear section cover plate assist mechanisms can offset the gravity of the rear section cover plate 2 itself when the rear section cover plate 2 is opened and closed, making the opening of the rear section cover plate 2 more labor-saving.
[0038] Among them, the rear section cover plate 2 and the mold 1 are hinged by the rear hinge shaft 9, and the rear section cover plate assist mechanism is a rear torsion spring 10 installed on the rear hinge shaft 9. The rear torsion spring 10 can drive the rear section cover plate 2 to swing up. When the rear section cover plate 2 swings up to a vertical state, the rear torsion spring 10 is in a free state. During the closing process of the rear section cover plate 2, the rear section cover plate 2 is subjected to the torsion force of the rear torsion spring 10. During the opening and closing process of the rear section cover plate 2, the torsion of the rear torsion spring 10 can offset the gravity of the rear section cover plate 2, making the opening of the rear section cover plate 2 more labor-saving, and when the rear section cover plate 2 is closed, it will not swing down at a very fast speed under the action of gravity.
[0039] Furthermore, 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 bar of the rear torsion spring 10 is connected to the legs, and the other torsion bar of the rear torsion spring 10 is connected to the hinged plates 11. The first rear torsion spring 10 and the second rear torsion spring 10 are respectively installed on both sides of the rear hinge shaft 9. The torsion forces of the first rear torsion spring 10 and the second rear torsion spring 10 are different. The initial angle of the torsion spring installation makes one set of torsion springs bear force 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 two sets of torsion springs are subjected to force, but it is easy to close under the action of gravity.
[0040] The utility model also includes a locking mechanism for locking the front section cover plate 3 when the front section cover plate 3 is flipped onto the rear section cover plate 2. The setting of the locking mechanism enables the front section cover plate 3 to be locked onto the rear section cover plate 2 when the front section cover plate 3 is flipped onto the rear section cover plate 2.
[0041] Specifically, the locking mechanism includes a hook 13 mounted on the front section cover plate 3 and a hook 14 hinged on the rear section cover plate 2. Preferably, the hook 14 is hinged on the rear section cover plate 2 via a damping shaft. When the front section cover plate 3 is flipped onto the rear section cover plate 2, the hook 14 swings to be inserted into the hook 13, locking the front section cover plate 3 onto the rear section cover plate 2.
[0042] As another preferred case of installation of the hook 14, the hook 14 is hinged on the mounting frame 18, and the mounting frame 18 is installed on both sides of the rear section cover plate 2. An elastic mechanism driving the hook 14 to swing up to abut against the side of the rear section cover plate 2 is installed on the rear section cover plate 2. The preferred elastic mechanism is a tension spring 17, one end of the tension spring 17 is connected to the hook 14, and the other end of the tension spring 17 is connected to the mounting frame 18. The tension spring 17 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 17 and the hook-shaped portion is inserted into the hook ring 13.
[0043] Furthermore, the mold 1 is provided with a locking mechanism for locking 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] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
