Description

Technical Field

[0001] The invention relates to the technical field of steel mold grabbing, in particular to a steel mold grabbing mechanism. Background Art

[0002] Steel molds have the characteristics of high strength, good rigidity, and not easy to deform. They can withstand the lateral pressure during concrete pouring and ensure the stability and accuracy of the concrete structure. In the construction process, it is a common practice to use steel molds to assist in the pouring of concrete. This method can ensure that the shape, size and position of the concrete structure meet the design requirements, while improving construction efficiency and quality.

[0003] And after the existing steel mold assists in forming the concrete, when the strength of the concrete reaches the design requirements, the steel mold can be demolded. Since one side of the steel mold is tightly fitted with one side of the concrete during the process of assisting the concrete forming by the steel mold, a lifting device is used to pull the steel mold to separate the steel mold from the concrete during demolding. However, in this process, the force points of this pulling method are on the back of the steel mold, and there are fewer force points. At the same time, since the concrete contains more steel bars, directly pulling the steel mold is not only easy to cause deformation of the steel mold and the steel bars, but also easy to damage the concrete surface.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] Please refer to Figures 1 to 5 A steel mold grabbing mechanism includes a connecting plate 1 and a mounting shell 2. The connecting plate 1 is connected to an external mechanical arm. One end of the mounting shell 2 is fixedly connected to the connecting plate 1. In this embodiment, a plurality of connecting holes are provided on the connecting plate 1, so as to facilitate installation and disassembly between the connecting plate 1 and the external mechanical arm. A telescopic support mechanism 3 is installed on the mounting shell 2, and connecting shells 4 are installed at both ends of the telescopic support mechanism 3.

[0041] See also Figures 6 to 8The telescopic support mechanism 3 includes a rotating block 31, a rotating sleeve 32, a rotating mechanism 33, a rotating screw 34, a connecting block 35 and a telescopic rod 36. The rotating block 31 is located inside the mounting shell 2, and the rotating block 31 is cylindrical. Two rotating sleeves 32 are provided. The two rotating sleeves 32 are respectively located on both sides of the mounting shell 2, and the ends of the two rotating sleeves 32 close to each other penetrate the mounting shell 2 and are fixedly connected to the rotating block 31. The rotating sleeve 32 is rotatably connected to the mounting shell 2;

[0042] The rotating mechanism 33 is located inside the mounting shell 2, and the rotating mechanism 33 is used to drive the rotating block 31;

[0043] One end of the rotating screw rod 34 is located inside the rotating sleeve 32, and the other end of the rotating screw rod 34 is fixedly connected to the connecting block 35, the connecting block 35 is fixedly connected to the connecting shell 4, and one end of the rotating screw rod 34 is threadedly connected to the rotating sleeve 32, and the thread directions of the two rotating screw rods 34 are opposite;

[0044] There are four telescopic rods 36 , which are distributed in pairs outside the two rotating screws 34 . One end of the telescopic rod 36 is fixedly installed outside the mounting shell 2 , and the other ends of the two telescopic rods 36 are fixedly connected to the corresponding connecting blocks 35 .

[0045] See also Figure 8 The rotating mechanism 33 includes a rotating motor 331, a first rotating gear 332 and a second rotating gear 333. The rotating motor 331 is fixedly mounted inside the mounting shell 2. The output end of the rotating motor 331 is fixedly connected to the first rotating gear 332. The first rotating gear 332 is meshedly connected to the second rotating gear 333. The second rotating gear 333 is fixedly sleeved on the outer side of the rotating block 31.

[0046] Specific implementation process: When the strength of the concrete reaches the design requirements, it will be connected to one end of the external mechanical arm through the connection hole on the connection plate 1. At the same time, the external mechanical arm will move the connection plate 1 to the outside of the steel mold with dismantling, and close to the central axis of the X-axis and Y-axis of the steel mold. Then, the first rotating gear 332 drives the second rotating gear 333 to rotate through the rotation of the rotating motor 331, and then the rotating block 31 is rotated. When the rotating block 31 rotates, the two rotating sleeves 32 at both ends are further rotated synchronously. When the rotating sleeve 32 rotates At the same time, a driving force is provided to the rotating screw 34. Since the rotating screw 34 is limited by the connecting block 35 and the two telescopic rods 36 on the outer side thereof, the rotating screw 34 is further moved in the direction away from the rotating sleeve 32. At this time, the telescopic rod 36 is in a stretched state until the four clamping members 71 at the auxiliary demoulding mechanism 7 move to both sides of the steel mold. Then, the external mechanical arm cooperates with the movement to make one side of the fixed side plate 713 of the four clamping members 71 contact the outer side of the steel mold. At this time, the rotating motor 331 stops running, and the connecting plate 1 is relatively fixed to the outer side of the steel mold.

[0047] A moving mechanism 5 is installed on the connecting shell 4, and two supporting frames 6 are connected to the moving mechanism 5, and the supporting frames 6 are slidably connected to the connecting shell 4;

[0050] That is, a protective shell 53 is arranged on the outside of the rotating motor 52, so as to realize the function of protecting the rotating motor 52. At the same time, when the distance between the two support frames 6 of the connecting shell 4 is adjusted, the rotating motor 52 is operated to rotate the bidirectional threaded screw 51. When the bidirectional threaded screw 51 rotates, a driving force in opposite directions of the two support frames 6 is provided. Due to the limiting action of the connecting shell 4, the two support frames 6 move in opposite directions.

[0051] An auxiliary demoulding mechanism 7 is installed on the support frame 6. The auxiliary demoulding mechanism 7 is used to assist in demoulding between the steel mold and the concrete. After the steel mold is separated from the concrete, the multiple auxiliary demoulding mechanisms 7 grab the steel mold to separate the steel mold from the concrete. In this example, the steel mold is provided with mounting holes corresponding to the steel bars on the concrete, so as not to affect the auxiliary molding of the concrete by the steel mold. At the same time, in this embodiment, the auxiliary demoulding mechanism 7 deviates from the multiple steel bars, so as not to affect the demoulding effect of the steel mold.

[0052] See also Figures 9 to 14 The auxiliary demoulding mechanism 7 includes a clamping member 71, a guide block 72, a prying mechanism 73 and a swinging member 74.

The reinforcing rod 732 is fixedly passed through one end of the prying plate 733, and both ends of the reinforcing rod 732 are rotatably connected to the support block 731. The pulling member 734 is installed on the support block 731, and the pulling member 734 is used to pull the prying plate 733 through the reinforcing rod 732.

[0056] See also Figure 12 to Figure 13The pulling member 734 includes a pulling cylinder 7341, a pulling rod 7342, a pulling frame 7343 and a pulling block 7344. The pulling cylinder 7341 is fixedly installed on one side of the support block 731, and a moving hole is provided on the support block 731. The pulling rod 7342 slides through one end of the moving hole, and the output end of the pulling cylinder 7341 is fixedly connected to one end of the pulling rod 7342, and the end of the pulling rod 7342 located outside the moving hole is fixedly connected to the pulling frame 7343. The pulling frame 7343 is U-shaped, and a support shaft 7345 is fixedly installed on one end of the pulling frame 7343, and one end of the pulling block 7344 is rotatably sleeved on the outside of the support shaft 7345. Two pulling protrusions are provided on the other end of the pulling block 7344. The two pulling protrusions are respectively located on both sides of the pry plate 733 and fixedly sleeved on the outside of the reinforcing rod 732.

[0057] See also Fig.10 The swing member 74 includes a positioning motor 741, a rotating disk 742, a swing shaft 743, a swing support rod 744 and a connecting shaft 745. The positioning motor 741 is fixedly installed on the support section 62, and the output end of the positioning motor 741 passes through the support section 62 and is fixedly connected to the rotating disk 742. The output end of the positioning motor 741 is rotatably connected to the support section 62. One end of the swing shaft 743 is fixedly installed on a side of the rotating disk 742 away from the positioning motor 741, and the swing shaft 743 deviates from the center of the rotating disk 742. One end of the swing support rod 744 is rotatably sleeved on the outside of the swing shaft 743, and the other end of the swing support rod 744 is rotatably sleeved on the outside of the connecting shaft 745. The connecting shaft 745 is fixedly installed on the guide block 72.

[0058] Specific implementation process: when the steel mold is demoulded and clamped between the cast concrete, one side of the two fixed side plates 713 at the two support frames 6 on the connecting shell 4 is in contact with the outer side of the steel mold, and then the steel mold is limited between the multiple fixed side plates 713 on both sides of the steel mold. At the same time, this setting does not affect the subsequent removal of the steel mold. At the same time, one side of the pry plate 733 at the support frame 6 is in contact with one side of the concrete;

[0059] Subsequently, the positioning motors 741 on the multiple support frames 6 are all running, and when the positioning motors 741 are running, the rotating disk 742 is rotated, and when the rotating disk 742 is rotating, the swing shaft 743 drives the swing support rod 744 to move, and the swing support rod 744 drives the guide block 72 to move through the connecting shaft 745 at the other end, and under the limiting action of the guide block 72 at the guide port, the guide block 72 further drives the pry plate 733 to move along the steel mold through the support plate, and the side of the pry plate 733 close to the steel mold is set as an inclined surface, and then when the pry plate 733 moves along the steel mold, it is possible to pry up the steel mold and the concrete, and at the same time, when the pry plate 733 moves along the steel mold, it is possible to pry up the steel mold and the concrete. When the pry plate 733 contacts one side of the steel mold and one end of the pry plate 733 enters between the steel mold and the concrete, the cylinder 7341 is pulled to operate, so that the pulling rod 7342 drives the pulling frame 7343 to move along the support block 731. When the pulling frame 7343 moves, the pulling block 7344 is synchronously driven to rotate. At the same time, the pulling block 7344 drives the reinforcing rod 732 to rotate under the limiting effect of the reinforcing rod 732. Since the pry plate 733 is fixedly installed on the reinforcing rod 732, the pry plate 733 is further rotated on the Y axis of the reinforcing rod 732, so that the inclined surface of the pry plate 733 pries up the steel mold, so that the steel mold is further separated from the concrete.

[0060] In the process of the steel mold being pried up and separated from the concrete by the prying plate 733, the steel mold can move relative to the four groups of fixed side plates 713 on its outer side, that is, move along the direction of the limiting horizontal plate 712. At the same time, the limiting horizontal plate 712 serves to limit the steel mold and prevent it from bouncing up.

[0061] And then, the two support frames 6 are moved along the outside of the steel formwork to completely separate the steel formwork from the concrete, and the four groups of fixed side plates 713 on the outside of the steel formwork clamp the steel formwork to each other, and at the same time, with the support of the four pry plates 733, the steel formwork is clamped to further stably separate the steel formwork from the concrete and the steel bars thereon, thereby achieving stable removal of the steel formwork and preventing deformation of the steel formwork.

[0062] Embodiment 2

[0063] See also Figure 13 to Figure 14 , Embodiment 2 is a further supplementary description of the pry plate 733 in Embodiment 1, specifically: the pry plate 733 is composed of a straight section 7331, an inclined prying section 7332 and a curved connecting section 7333;

[0064] The straight section 7331 is close to one side of the concrete, and the inclined prying section 7332 is in the form of a slope, so that the steel formwork can be pried up by the inclined prying section 7332 to separate the steel formwork from one side of the concrete. At the same time, the curved connecting section 7333 is the connection with the reinforcing rod 732, thereby ensuring that the pry plate 733 is stably connected to the reinforcing rod 732. At the same time, when the pry plate 733 pries up the steel formwork, the curved connecting section 7333 never contacts the concrete. The pry plate 733 is made of high-carbon steel material, so the pry plate 733 has high strength and high hardness, ensuring that the pry plate 733 can stably pry up the steel formwork.
