Description

Technical Field

[0001] The utility model belongs to the field of prefabricated part production equipment, and in particular relates to a die table hanger. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] A prefabricated component production line may involve multiple production equipment, such as a placing machine, a vibrating table, a curing kiln, and a palletizer. Since the three-dimensional curing kiln and the palletizer are large-scale equipment, the production line construction cost is relatively high, and the energy consumption of the curing kiln is also high. In some cases, it is necessary to meet certain production needs without using three-dimensional curing kilns and palletizers. This kind of production line will greatly reduce the construction cost of the production line because it does not involve large equipment such as three-dimensional curing warehouses and palletizers. At the same time, the use of stacked molds for centralized maintenance can also minimize energy consumption. For this situation, it is necessary to design a special hoist to simplify the mold stacking process and improve the efficiency of the production line. Utility Model Content

[0006] A mold table hoist, which includes a frame and a grab arm device arranged at the four corners of the frame, the grab arm device includes a clamping arm, a clamping claw arranged at the bottom end of the clamping arm and a cylinder connected to the top end of the clamping arm, the upper end of the clamping arm is located above the frame, and the lower end is located below the frame. A cylinder seat is provided on the top surface of the frame, and the cylinder body of the cylinder is rotatably installed on the cylinder seat, and its piston rod is rotatably connected to the upper end of the clamping arm. A connecting seat is provided on the top surface of the frame, and the middle part of the clamping arm is connected to the connecting seat through a rotating shaft. The clamping claw is arranged inwardly for grasping the mold table.

[0007] Furthermore, each gripping arm device comprises two clamping arms arranged in parallel, a cross brace is provided between the upper and lower ends of the two clamping arms, and the piston rod of the oil cylinder is connected to the cross brace located at the upper end.

[0008] Furthermore, an X-shaped reinforcement rod is fixedly installed between the two clamping arms.

[0009] Furthermore, the clamping arm is located on the outside of the frame, and its upper and lower ends are inclined inwards, respectively used to connect with the oil cylinder and grasp the mold platform.

[0010] Furthermore, the frame includes a left frame and a right frame that are symmetrically arranged, and the left frame and the right frame are connected by bolts.

[0011] Furthermore, hanging rings are provided on both the left and right sides of the frame.

[0012] The beneficial effects of the utility model are:

[0013] The utility model has a frame for hoisting and a grab arm device installed on the frame. During hoisting, the mold platform is located below the frame. The hydraulic cylinder drives the clamp arm to deflect and hold the mold platform tightly. Then the overhead crane can drive the frame to move, so as to realize the hoisting and movement of the mold platform. There is no need to use a stacking machine. At the same time, the clamp arm is located on the side of the mold platform, which can facilitate the stacking operation of the mold platform and centrally maintain the mold platform. It can also simplify the process of stacking the mold platform and greatly improve the efficiency of the production line. The overall structure of the hoist is simple, and the mold platform is held tightly by four grab arm devices, so the overall reliability is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] As attached Figure 1-3 As shown, the utility model discloses a die table hoist, which specifically comprises a frame 1 and a grab arm device. A hoisting ring 7 is provided on the frame 1 for connecting with a crown block to realize hoisting and movement.

[0019] The grab arm device includes a clamp arm 2, a clamping claw 4 and an oil cylinder 6. The clamp arm 2 is located at the outer side of the frame 1, with its upper end located above the frame 1 and its lower end located below the frame 1. A cylinder seat 9 is fixedly installed on the top surface of the frame 1. The cylinder body of the oil cylinder 6 is connected to the cylinder seat 9 through a rotating shaft, and the piston rod is connected to the upper end of the clamp arm 2 through the rotating shaft. A clamping claw 4 is arranged at the lower end of the clamp arm 2. The clamping claw 4 is a bending portion arranged at the lower end of the clamp arm 2 and is bent toward the inside. A connecting seat 8 is arranged on the frame 1. The middle part of the clamp arm 2 is connected to the connecting seat 8 through a solder resist. Driven by the oil cylinder 6, the clamp arm 2 can deflect around the connecting shaft between the connecting seat 8 and the clamp arm 2. The die table is located at the inner side of the four groups of the grab arm devices. When the clamping claw 4 of the four groups of the grab arm devices deflects inward, the die table can be grasped, and the overhead crane can hoist and transport the die table. After being transferred to the designated position, the oil cylinder 6 drives the clamping claw 4 to deflect outward, thereby releasing the die table.

[0020] The grab arm device of the utility model grabs the mold platform from the side, and can be connected to the overhead crane on the top of the frame 1, so as to realize hoisting and transportation, and can stack the mold platforms. In some production lines that do not use three-dimensional curing kilns and stacking machines, centralized curing is realized in the form of stacking mold platforms, which minimizes energy consumption.

[0021] As a further improvement of the present invention, each gripping arm device has two clamping arms 2 arranged in parallel, a cross brace 3 is provided between the upper and lower ends of the two clamping arms 2, and an X-shaped reinforcing rod 5 is provided between the two cross braces 3, the ends of the reinforcing rod 5 are respectively fixedly connected to the two clamping arms 2, and the piston rod of the oil cylinder 6 is connected to the cross brace 3 located above.

[0022] Since the clamp arm 2 is located at the outer side of the frame 1, from the perspective of spatial layout, in order to facilitate the connection between the piston rod of the cylinder 6 and the cross brace 3, the upper end of the clamp arm 2 is inclined inward, which can reduce the stroke of the piston rod; and the lower end of the clamp arm 2 is also inclined inward, which will also facilitate the cooperation between the clamping claw 4 and the mold platform and reduce the stroke of the piston rod.

[0023] As a further improvement of the present invention, the frame 1 is formed by left and right splicing, including a symmetrical left frame 101 and a right frame 102. After the grab arm device and other components are assembled on the corresponding left and right frames, the left and right frames are fixed together with bolts to improve assembly efficiency.

[0024] The utility model can be applied to prefabricated component production lines that do not use three-dimensional curing kilns and stacking machines to realize the hoisting and transportation of mold pallets. At the same time, since the grab arm device is located on the side of the mold pallet, the mold pallet is grabbed by deflecting the clamp arm, which can simplify the mold pallet stacking process and improve the production line efficiency.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
