It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.
[0037] In the description of the utility model, it should be pointed out that the structure, proportion, size and the like shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for understanding and reading by those skilled in the art, and are not used to limit the limiting conditions of the utility model that can be implemented, so they do not have the technical essence, any modification of the structure, change of the proportion relationship or adjustment of the size, which does not affect the effects and purposes that the utility model can produce, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" and the like cited in the specification are only for the convenience of clear description, and are not used to limit the scope of the utility model that can be implemented, the change or adjustment of the relative relationship, without substantially changing the technical content, is also regarded as the scope of the utility model that can be implemented.
[0038] As shown in Figures 1-4 The embodiment of the utility model provides an assembly type prefabricated slab auxiliary demolding device, which is installed on a turnover mechanism to be turned over under the action of the turnover mechanism, wherein the turnover mechanism is a conventional device in the art, and since the utility model does not make any improvement on it, the specific structure and working mode thereof will not be described here.
[0039] Specifically, the assembly type prefabricated slab auxiliary demolding device comprises a fixed support 11, a fixed support 11, a first adjusting support 12, a second adjusting support 13, a third adjusting support 14 and an adjusting assembly: the fixed support 11 has a first end 101 and a second end 102 which are perpendicular to each other; the first adjusting support 12 is slidably connected to the fixed support 11 and is arranged close to the first end 101 of the fixed support 11; the second adjusting support 13 is slidably connected to the fixed support 11 and is arranged close to the second end 102 of the fixed support 11; the third adjusting support 14 is slidably connected to one end of the first adjusting support 12 and the second adjusting support 13 away from the fixed support 11; the adjusting assembly comprises a gear 21 rotatably arranged on the first adjusting support 12, a rack 22 and a threaded rod 23 connected to the gear 21, one end of the rack 22 is connected to the third adjusting support 14, the other end penetrates through the first adjusting support 12 and is engaged with the gear 21, the threaded rod 23 penetrates through the first adjusting support 12 and one end extends to the first end 101 of the fixed support 11, and the axis of the rack 22 is perpendicular to that of the threaded rod 23;
[0040] The mounting cavity 15 is formed between the fixed support 11 and the first adjusting support 12, the second adjusting support 13 and the third adjusting support 14, so that the first adjusting support 12, the second adjusting support 13 and the third adjusting support 14 are driven to move close to the fixed support 11 by rotating the threaded rod 23, so as to realize clamping and fixing of the mold plate in the mounting cavity 15.
[0041] In the embodiment of the utility model, in use, first, the prefabricated plate mold to be demolded is placed in the mounting cavity 15, then the threaded rod 23 is rotated, the threaded rod 23 drives the gear 21 to rotate, the gear 21 meshes with the rack 22 and pushes the rack 22 to move in the horizontal direction. Since one end of the rack 22 is connected to the third adjusting support 14, the movement of the rack 22 drives the third adjusting support 14 to slide to both sides. The movement of the third adjusting support 14 further drives the first adjusting support 12 and the second adjusting support 13 to move synchronously, so that the length and width of the mounting cavity 15 change until the mold is clamped firmly. In the case that the mold is clamped firmly, the whole device is turned over, so that the mold faces downward. Due to the gravity of the prefabricated plate, the concrete product gradually separates from the mold, and natural demolding is realized. After demolding is completed, the threaded rod 23 is rotated, so that each adjusting support returns to the initial position, and the mounting cavity 15 returns to the default state, so as to place a new mold for the next demolding operation. It should be understood that the clamping force of the mounting cavity 15 on the mold plate should not be too large, so as to avoid applying too large lateral pressure on the side surface of the mold plate, so that the mold plate deforms, the friction between the prefabricated plate and the mold increases, and the prefabricated plate is difficult to demold naturally after turning over. At the same time, according to the material and size of the mold, the clamping force of the mounting cavity 15 can be controlled to be 30% to 50% of the bearing force of the mold, or a gap of 0.5 to 2 mm is reserved between the mold and the mounting cavity 15 during clamping, so that the mold can release the prefabricated plate smoothly after turning over.
[0042] Specifically, as shown in Figures 2-3 The rack 22 is provided with a limiting block 24, the limiting block 24 is slidingly connected to the first adjusting support 12, the limiting block 24 keeps the rack 22 in a fixed track during movement, avoids shaking or deviation, and improves the stability of the adjusting and fixing process.
[0043] Specifically, as shown in Figure 4As shown in the utility model embodiment, the fixed support 11, the second adjusting support 13 and the third adjusting support 14 are provided with matched connecting frames 30 and holes 40, the connecting frame 30 is arranged in the hole 40, and the relative position of the adjusting support can be ensured to be more fixed after the connecting frame 30 is arranged in the hole 40, mutual sliding or deviation between them is avoided, and the precision of the overall adjusting and fixing process is improved.
[0044] Specifically, as Figures 2-3 As shown in the utility model embodiment, the outer side of the first adjusting support 12 is provided with a mounting frame 50, a driving wheel 60 is rotatably arranged on the mounting frame 50, the driving wheel 60 is connected to one end of the threaded rod 23 away from the fixed support 11, the function of adjusting the size of the mounting cavity 15 is realized by driving the driving wheel 60 to rotate to drive the threaded rod 23 to rotate, thereby facilitating use, wherein, in the driving source selection of the driving wheel 60, a motor can be installed on the mounting frame 50 for mounting the driving wheel 60, and is connected to the driving wheel 60 through a belt.
[0045] Based on the above scheme, as Figures 1-2 As shown in the utility model embodiment, the inner walls of the fixed support 11, the first adjusting support 12, the second adjusting support 13 and the third adjusting support 14 all extend inwardly to form a stepped surface, when the mold is placed in the mounting cavity 15, the edge thereof is in contact with the stepped surface, the accurate positioning of the mold in the length and width directions is ensured, unnecessary displacement is prevented when adjusting and moving, the position of the mold is fixed through close contact with the stepped surface, thereby ensuring the stability when subsequent overturning is performed.
[0046] Based on the above scheme, as Figures 1-2 As shown in the utility model embodiment, the inner walls of the fixed support 11, the first adjusting support 12, the second adjusting support 13 and the third adjusting support 14 are all provided with a rubber layer 80, the rubber layer 80 is located above the stepped surface, the rubber layer 80 can prevent excessive lateral support force from being generated during clamping, and affect demolding. Specifically, the traditional rigid clamping mode can cause the mold and the prefabricated plate to be pressed too tightly, increase the demolding resistance, and even cause the prefabricated plate to still fail to be demolded smoothly after overturning. Since the rubber layer 80 has a certain elasticity, flexible buffering can be provided during clamping, the clamping force is prevented from being excessively concentrated on the side, the lateral support force is reduced, and smooth demolding after overturning is ensured.
[0047] Based on the above solutions, such as Figures 1-2 As shown in the embodiment of this utility model, the top of the fixed bracket 11, the first adjusting bracket 12, the second adjusting bracket 13 and the third adjusting bracket 14 are all provided with lifting rings 90. The lifting rings 90 can be used to cooperate with lifting equipment (such as cranes, overhead cranes, chain hoists, etc.) for overall or partial lifting, reducing the difficulty of manual handling, especially when the mold size is large or the demolding device is heavy, thus improving work efficiency.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
