Description

Technical Field

[0001] This utility model belongs to the field of crankshaft hoisting technology, specifically relating to a hoisting assembly for engine crankshaft production. Background Technology

[0002] When hoisting a crankshaft, a hoisting assembly is usually used. Existing hoisting assemblies typically use hooks on both sides of a crossbeam to hook the crankshaft, and then use lifting rings installed on the crossbeam to lift the crossbeam. However, during the hoisting process, the crankshaft is in a swaying state as the crossbeam moves, which can easily affect the stability of the hoisting and pose a safety hazard. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a hoisting assembly for engine crankshaft production, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this hoisting assembly for engine crankshaft production to solve its technical problems is as follows:

[0005] A lifting assembly for engine crankshaft production is provided, including a crossbeam. Mounting seats are fixedly installed at both ends of the crossbeam. Hooks are fixedly installed on both sides of the bottom surface of the mounting seats. A vertical rod is provided between the hooks. The vertical rod is rotatably mounted between the two hooks via a torsion spring and a rotating shaft. A groove is formed at the lower end of the vertical rod. An L-shaped rod is provided below the vertical rod. A support is provided below the L-shaped rod. A spring is fixedly installed on each side of the support, and its upper end is fixedly connected to the L-shaped rod. A pointed tip is fixedly installed on the L-shaped rod, and the pointed tip can be inserted into the corresponding groove.

[0006] Furthermore, the crossbeam includes a threaded tube, with threaded screws installed on both sides of the threaded tube. The screws are fixedly connected to corresponding mounting seats, and the threads of the screws on both sides are in opposite directions.

[0007] Furthermore, a sleeve is rotatably installed on the threaded pipe, and a lifting ring is fixedly installed on the sleeve.

[0008] Furthermore, a threaded hole is formed in the middle of the sleeve, and a positioning screw is installed in the internal thread of the threaded hole.

[0009] Furthermore, a horizontal tube is provided below the threaded tube, and a sliding rod is provided inside the horizontal tube. One end of the horizontal tube is fixedly connected to one of the mounting seats, and one end of the sliding rod is fixedly connected to the other mounting seat.

[0010] Furthermore, a first through hole is provided on the vertical rod, and a second through hole is provided on the hook, with a plug fitting into each of the second through holes.

[0011] Furthermore, an arc-shaped groove is formed on the vertical rod.

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

[0013] 1. This utility model provides a hoisting assembly for engine crankshaft production. In use, the hooks on both sides are hung on the corresponding positions of the crankshaft. The weight of the crankshaft causes the L-shaped rod to descend, and the tip no longer limits the vertical rod. The vertical rod rotates under the elastic force of the torsion spring and rests on the crankshaft, fixing it in place. This allows the device to limit the crankshaft during hoisting by using the vertical rod, reducing crankshaft movement during hoisting, improving hoisting stability, and making hoisting safer.

[0014] 2. In an example of this utility model, a hoisting assembly for engine crankshaft production allows for easy adjustment of the distance between two mounting seats by means of screws with opposite thread directions when rotating the threaded tube, thereby facilitating the adjustment of the distance between the hooks on both sides.

[0015] 3. A hoisting assembly for engine crankshaft production according to this utility model example can be easily hoisted by means of a lifting ring.

[0016] 4. In the example of this utility model, a hoisting assembly for engine crankshaft production can be used to easily fix the sleeve by means of a positioning screw.

[0017] 5. A hoisting assembly for engine crankshaft production according to this utility model example can limit the position of the mounting base by means of a horizontal tube and a sliding rod, thereby preventing the mounting base from rotating.

[0018] 6. In the present invention, a hoisting assembly for engine crankshaft production is provided. When the vertical rod is rotated to the alignment of the first through hole and the second through hole, the vertical rod can be fixed by inserting the insertion rod into the first through hole and the second through hole, which facilitates the limiting of the crankshaft position.

[0019] 7. A hoisting assembly for engine crankshaft production according to this utility model example can easily contact the crankshaft through an arc groove. Attached Figure Description
