Description

Technical Field

[0001] This utility model relates to the field of vibration molding technology for concrete core molds, and specifically to a lifting device for vibration molding of concrete core molds. Background Technology

[0002] The vibration molding process for concrete core molds involves transferring vibrational energy of a specific frequency, amplitude, and excitation force to the concrete mixture after pouring. This significantly reduces the adhesion and internal friction, transforming the mixture into a heavy liquid state. As the aggregates settle and align under their own weight, air is expelled from the concrete mixture, voids are eliminated, and the aggregates and cement paste achieve a dense arrangement and effective filling of the mold. The molded core molds require lifting equipment for transport. A search revealed existing technology (Announcement No.: CN202322629255.1) for concrete pipe pile lifting equipment, which describes "a pair of bases I and a pair of electric cylinders I working together effectively to adapt to..." To provide a stable and effective lifting foundation for the hoisting of concrete pipe piles of different lengths; the pair of bases II and the hoisting plates in the pair of locking components are fixed structures and are the main support components for hoisting, providing sufficient mechanical support for the concrete pipe piles; the electric cylinder II, multiple support rods and multiple locking legs form a multi-link linkage support structure, which assists the hoisting plate in providing an effective stabilizing structure for the concrete pipe piles, avoiding swaying or slippage of the concrete pipe piles during hoisting, effectively improving the safety of hoisting operations and increasing work efficiency. However, in the existing technology, the linkage support structure clamped at both ends of the concrete pipe core mold has a wide span, resulting in a large hoisting body volume, which is not conducive to hoisting movement. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a lifting device for the vibration molding process of concrete pipe core molds is provided to solve the problem that the large span of the linkage support structure clamping the two ends of the concrete pipe core mold in existing technologies results in a large lifting device volume, which is not conducive to lifting and moving.

[0004] To achieve the above objectives, a lifting device for vibration molding of concrete core molds is provided, comprising: a lifting device body and an electric hoist, wherein the electric hoist is fixedly installed on the upper surface of the lifting device body.

[0005] The lifting device body has shaft connecting blocks sleeved on the left and right sides via fixing blocks. The lower end of the shaft connecting block is connected to a chain lock. The lower end of the chain lock is fastened to an adjusting plate frame via a latch. The front and rear ends of the adjusting plate frame are connected to the outer clamping plate of the mold surface via an electric cylinder. The adjusting plate frame is connected to the inner clamping plate of the mold surface via a limiting groove. An adjusting screw is installed on the side end face of the adjusting plate frame. The surface of the adjusting screw is connected to the inner clamping plate of the mold surface via a limiting plate.

[0006] Furthermore, a connecting block is welded to the middle of the upper surface of the lifting device body, and the electric hoist is connected to a lifting rope; and the lifting rope runs through the surface of the lifting device body.

[0007] Furthermore, an elastic pad is bonded to the lower surface of the lifting device body; and the elastic pad is in close contact with the upper surface of the concrete pipe core mold; and a section length adjuster is installed on the surface of the chain lock.

[0008] Furthermore, two sets of outer mold plates and inner mold plates are symmetrically distributed at the center of the side end of the adjustment plate frame, and anti-slip rubber pads are glued to the sides of both the outer mold plates and the inner mold plates.

[0009] Furthermore, electric cylinders are embedded and fixed at the front and rear ends of the adjustment plate frame, and a limit groove is opened on the side of the adjustment plate frame; and the side end of the outer clamping plate of the mold surface is connected in the limit groove.

[0010] Furthermore, one end of the adjusting screw is connected to the adjusting plate frame via a bearing; and the other end of the adjusting screw is welded with an adjusting column head.

[0011] Furthermore, two sets of fixing ring blocks are welded to the side of the adjustment plate frame; and the surface of the fixing ring blocks is connected to the chain lock by a buckle.

[0012] The beneficial effects of this utility model are as follows: the lifting device for the vibration molding process of concrete pipe core mold utilizes the chain locks on the left and right sides of the lifting device body to connect to the adjusting plate frame. The electric cylinder and adjusting screw inside the adjusting plate frame drive the outer clamping plate and the inner clamping plate of the mold surface to move, so that the clamping plate of the mold surface holds the pipe ends on both sides of the concrete pipe core mold, effectively reducing the overall volume of the concrete pipe core mold lifting device, while further stabilizing the clamping of the concrete pipe core mold, ensuring the stable movement of the lifted concrete pipe core mold, enhancing the stability of rope lifting, and improving the practicality of the special lifting device for concrete pipe core mold.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a lifting device for the vibration molding process of concrete pipe core mold, including: a lifting device body 1 and an electric hoist 2, wherein the electric hoist 2 is fixedly installed on the upper surface of the lifting device body 1.

[0020] The left and right sides of the lifting device body 1 are fitted with shaft connecting blocks 31 through fixing blocks 13. The lower end of the shaft connecting block 31 is connected to a chain lock 3. The lower end of the chain lock 3 is fastened to an adjusting plate frame 5 through a buckle 33. The front and rear ends of the adjusting plate frame 5 are connected to the outer clamping plate 4 of the mold surface through an electric cylinder 51. The adjusting plate frame 5 is connected to the inner clamping plate 41 of the mold surface through a limiting groove 52. An adjusting screw 43 is installed on the side end face of the adjusting plate frame 5. The surface of the adjusting screw 43 is connected to the inner clamping plate 41 of the mold surface through a limiting plate 44.

[0021] First, the hoisting rope 21 is connected to the concrete core mold formed by vibration process using the electric hoist 2. Then, the adjusting plate frame 5 is moved to both sides of the concrete core mold. The electric cylinder 51 pushes the outer clamping plate 4 of the mold surface to fit with the outer surface of the concrete core mold. Then, the adjusting screw 43 is manually rotated to make the inner clamping plate 41 of the mold surface fit with the inner side of the concrete core mold. The hoisting equipment connected to the upper end of the hoisting body 1 is used to move the hoisting body 1 upward, which can drive the concrete core mold to move.

[0022] In this embodiment, a connecting block 11 is welded to the middle of the upper surface of the lifting device body 1, and a lifting rope 21 is connected to the electric hoist 2 via a drive; the lifting rope 21 passes through the surface of the lifting device body 1. An elastic pad 12 is bonded to the lower surface of the lifting device body 1; the elastic pad 12 is in close contact with the upper surface of the concrete pipe core mold, and a section length adjuster 32 is installed on the surface of the chain lock 3.

[0023] In a preferred embodiment, the electric hoist 2 lifts and moves the concrete core mold via the hoisting rope 21. The elastic pad 12 facilitates the holding of the lifted concrete core mold. The section length adjuster 32 facilitates the adjustment of the length of the chain lock 3, allowing the position of the adjusting plate frame 5 to be adjusted according to the length of the chain lock 3, so that the adjusting plate frame 5 can be moved to the side end of the concrete core mold.

[0024] In this embodiment, two sets of outer mold clamping plates 4 and inner mold clamping plates 41 are symmetrically distributed on the side of the adjustment plate frame 5. Anti-slip rubber pads 42 are glued to the sides of both the outer mold clamping plates 4 and the inner mold clamping plates 41.

[0025] As a preferred embodiment, the outer clamping plate 4 and the inner clamping plate 41 of the mold face are secured to the molded concrete core mold by means of the anti-slip rubber pad 42, ensuring the clamping effect of the outer clamping plate 4 and the inner clamping plate 41 of the mold face.

[0026] In this embodiment, electric cylinders 51 are embedded and fixed at the front and rear ends of the adjusting plate frame 5, and limit grooves 52 are opened on the side of the adjusting plate frame 5; and the side end of the outer clamping plate 4 of the mold surface is connected in the limit groove 52. Two sets of fixing ring blocks 53 are welded to the side of the adjusting plate frame 5; and the surface of the fixing ring blocks 53 is suspended by the chain lock 3 through the buckle 33.

[0027] In a preferred embodiment, the electric cylinder 51 is used to move the outer clamping plate 4 of the mold surface into the limiting groove 52, so that the outer clamping plate 4 and the inner clamping plate 41 of the mold surface clamp the side end of the concrete core mold, which facilitates further stabilization of the concrete core mold, ensures stable movement of the hoisted concrete core mold, and enhances the stability of rope hoisting. The adjustable plate frame 5 and the mold clamping plate facilitate the reduction of the hoisting body volume and avoids restriction of hoisting movement.

[0028] In this embodiment, one end of the adjusting screw 43 is connected to the adjusting plate frame 5 via a bearing; and the other end of the adjusting screw 43 is welded with an adjusting head 45.

[0029] As a preferred implementation, the adjusting column head 45 facilitates the rotation of the adjusting screw 43, so that the limiting plate 44 on the surface of the adjusting screw 43 converts the rotational motion into linear motion, thereby driving the inner clamping plate 41 of the mold surface to move and fit into the inner mold surface of the concrete core mold.

[0030] This utility model of a lifting device for the vibration molding process of concrete pipe core molds effectively solves the problem in the prior art where the span of the linkage support structure clamping the two ends of the concrete pipe core mold is too wide, resulting in a large lifting device volume that is not conducive to lifting and moving. It effectively reduces the overall volume of the concrete pipe core mold lifting device, while further stabilizing the clamping of the concrete pipe core mold, ensuring stable movement of the lifted concrete pipe core mold, enhancing the stability of rope lifting, and improving the practicality of the special lifting device for concrete pipe core molds. It is suitable for lifting devices used in the vibration molding process of concrete pipe core molds.
