Description

Technical Field

[0001] The utility model relates to the technical field of EMS spreader mechanisms, in particular to a novel EMS spreader mechanism. Background Technique

[0002] ‌The EMS spreader mechanism is a device used for the handling and transfer of heavy loads. It adopts a modular design, with a compact structure, which improves the manufacturing efficiency and reduces the manufacturing cost. The EMS spreader is a workpiece carrier in the automobile production process and can automatically run and lift during operation, with high flexibility.

[0003] For example, the Chinese authorized patent with the publication number CN217972251U (a shock absorption and damping mechanism for an EMS spreader): It includes a spreader frame. At the upper end of the spreader frame, two left bearing seats and two right bearing seats are symmetrically arranged. Between the two left bearing seats, a left rotating connecting rod is arranged. Between the two right bearing seats, a right rotating connecting rod is arranged. Two left hanging legs extending downward are fixed on the left rotating connecting rod. Two right hanging legs extending downward are fixed on the right rotating connecting rod. A first rotating block is arranged at the middle part of the right rotating connecting rod and inclined downward. At the lower end of the middle part of the spreader frame, a cylinder is hinged. The output end of the cylinder is hinged to one end of the first rotating block. Four shock absorption and damping mechanisms are respectively arranged on the spreader frame. By the telescopic movement of the cylinder to push the first rotating block, the spreader is driven to open and close. When the hanging legs are closed, the overall shaking amount of the spreader is reduced through the shock absorption and damping mechanisms, making the equipment operation more stable.

[0004] However, for the EMS spreader in the above-mentioned prior art, due to the relatively large self-weight of the cab of some vehicle models, the upper section of the cab door frame will be squeezed and deformed during the hoisting process, seriously affecting the product quality and reducing the production efficiency. Therefore, it does not meet the existing requirements, and for this reason, we propose a novel EMS spreader mechanism. Content of the Utility Model

[0005] The purpose of the utility model is to provide a novel EMS spreader mechanism to solve the problem in the prior art that for the EMS spreader in the above-mentioned background technique, due to the relatively large self-weight of the cab of some vehicle models, the upper section of the cab door frame will be squeezed and deformed during the hoisting process, seriously affecting the product quality and reducing the production efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A novel EMS spreader mechanism includes a self-propelled trolley group. A support frame is arranged below the self-propelled trolley group. Electric push rods are arranged on the front and rear end faces of the support frame. A first front cross beam is arranged on one side below the support frame, and a first rear cross beam is arranged on the other side below the support frame. A second front cross beam is arranged on one side of the first front cross beam, and a second rear cross beam is arranged on one side of the first rear cross beam.

[0007] Preferably, eccentric locking pins are provided at the front and rear ends of one end face of the first front cross beam, the first rear cross beam, the second front cross beam, and the second rear cross beam, and lifting holes are provided at the front and rear ends of the tops of the first front cross beam, the first rear cross beam, the second front cross beam, and the second rear cross beam.

[0008] Preferably, lifting ropes are installed above the first front cross beam and the first rear cross beam, and spring balancers are provided above the second front cross beam and the second rear cross beam.

[0011] Preferably, a connecting rod is installed on the rotating frame, and a support plate is provided at the bottom of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing the first front cross beam, the first rear cross beam, the second front cross beam, and the second rear cross beam, and adopting a four-point lifting scheme to lift the process holes of the vehicle body, the front and rear lifting points are divided into two groups of front cross beams and rear cross beams. The front end of the cross beam is connected and locked to the process holes of the vehicle body by eccentric pin shafts.
