Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sand cores, in particular to a sand core transport airbag sling. Background Art
[0002] CMB is developing a large diesel clutch housing. The casting itself has a complex internal structure and is heavy. During manufacturing, a large number of sand cores are required to ensure the internal shape of the casting. However, due to the large mass of the sand cores themselves, sand cores are often damaged and wasted during transportation and assembly. Sand cores also occasionally fall during lifting, posing a safety hazard. Therefore, CMB developed a sand core transfer hoist to improve this phenomenon. This provides a technical foundation for improving the company's production capacity of large castings, and at the same time provides practical experience for innovation in casting processes for other types of cast iron parts. Through improvements in casting processes and production process methods, it ultimately achieves high-quality production and manufacturing levels.
[0003] Existing technology, application number: CN2018210885058, currently, a crane with a cloth belt is often used in the transfer process of large sand cores. This method has low safety and efficiency, and seriously damages the surface of the sand cores. To ensure safety, efficiency and quality of sand core transfer, CMB has developed corresponding transfer slings according to different product structures.
[0004] Therefore need to design a kind of sand core transport air bag sling to solve above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a sand core transport airbag sling to overcome the above-mentioned deficiencies in the current prior art.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A sand core transport airbag sling, which includes a rear cover, a screw rod arranged around the rear cover and passing through the rear cover, a support plate connected to the screw rod by bolts and nuts and placed under the rear cover, a plurality of groups of airbag frames arranged on the support plate, and an airbag arranged in the airbag frame, the airbag frames are arranged opposite to each other in pairs, and the opposite surfaces of the airbag frames are provided with airbag installation grooves for cooperating with the installation of the airbags, the top of the airbag frame is provided with an air vent for cooperating with the connection of the airbag, the airbag is placed in the airbag installation groove, and limiting columns are also provided on both sides of the rear cover, and the limiting columns are respectively provided on both sides of the airbag frames on both sides.
[0008] Preferably, a controller is further provided on the top of the rear cover, and the controller is used to control the expansion and contraction of each airbag.
[0009] Preferably, a lifting ring or a force-saving frame connecting device is also provided on the rear cover.
[0010] Preferably, a plurality of vent holes are provided on the rear cover.
[0011] The beneficial effects of the present invention are as follows: the present technical solution clamps the sand core module through a controllable airbag clamping assembly without damaging the surface of the sand core, while ensuring safety, sand core transfer efficiency and sand core quality. The airbag inflates and clamps different parts, so it is suitable for clamping sand cores of different shapes, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0019] Reference Figures 1 to 4A sand core transport airbag sling comprises a rear cover 3, a screw rod 2 arranged around the rear cover and passing through the rear cover, a support plate 6 connected to the screw rod by bolts and nuts and placed under the rear cover, a plurality of airbag frames 7 arranged on the support plate 6, and an airbag 8 arranged in the airbag frame;
[0020] The airbag frames 7 are arranged in pairs, and the opposite sides of the airbag frames are provided with airbag mounting grooves 71 for mounting airbags. The tops of the airbag frames are provided with vent holes 72 for connecting the airbags. The airbags are placed in the airbag mounting grooves.
[0021] In order to facilitate the control of each airbag, a controller 4 is also provided on the top of the rear cover, and the controller is used to control the expansion and contraction of each airbag; the controller controls all airbags to work simultaneously through the cylinder parallel air pipe;
[0022] In order to facilitate limiting the tightening position and prevent the sand core from being crushed by the wrong clamping surface, limit posts 5 are further provided on both sides of the rear cover. The limit posts are respectively provided on both sides of the airbag frames.
[0023] In order to facilitate the installation of small lifting equipment, a lifting ring 1 or a force-saving frame connection device is also provided on the rear cover;
[0024] In order to facilitate the ventilation of the airbag and not affect the clamping position, a plurality of ventilation holes are opened on the back cover to cooperate with the threading;
[0025] In this embodiment, the installation part of the lifting equipment is fixedly connected to the lifting ring 1 on the top of the rear cover or the force-saving frame connecting device. The lifting equipment drives the entire lifting device to move and move it to the sand core mold. The limiting columns 5 at both ends are driven to be clamped into the limiting holes corresponding to the sand core for limiting. At the same time, the sand core is placed in the middle of the relatively set airbag frame 7 or the entire airbag frame 7 is placed inside the sand core. After placement and installation, the high-lifting equipment is moved to other positions, closed, and the airbag is exhausted. The exhaust is exhausted by standing up and contracting. The sand core is lowered after losing the clamping force, thereby completing the handling work.
[0026] The benefits of the present invention are that the technical solution clamps the sand core module through a controllable airbag clamping assembly without damaging the sand core surface, while ensuring safety, sand core transfer efficiency and sand core quality. The airbag inflates and clamps different parts, so it is suitable for clamping sand cores of different shapes and has high practicality.
