Description

Technical Field

[0001] This utility model belongs to the field of assembly tooling structure technology, and in particular relates to a modular basin beam hoisting device for commercial vehicles. Background Technology

[0002] Each front spring rear support and basin beam weighs approximately 25kg. Employees carry and lift these components, and the assembly of these parts is scattered across multiple workstations. This frequent lifting and lifting of the front spring rear support and basin beam results in prolonged heavy physical labor. The front spring rear support and basin beam have an internally threaded assembly structure. Assembly errors after the front spring rear support assembly lead to misalignment of the internal thread mounting holes, making installation difficult and creating a bottleneck process. Based on the assembly relationship of the basin beam assembly, the left / right front spring rear supports, basin beam, and basin beam support are disassembled, transported, and assembled into a modular assembly. Therefore, based on the modular requirements, there is an urgent need to design a lifting fixture suitable for various modular basin beams to reduce the labor intensity of employees and eliminate heavy physical labor.

[0003] To address this, we propose a modular basin beam hoisting device for commercial vehicles. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology that when employees are performing assembly work, the parts are scattered across multiple workstations, and employees need to frequently lift and install front springs, rear supports, and basin beams. This long-term heavy physical labor may lead to misalignment of internal thread mounting holes, installation difficulties, and bottleneck processes, which is not conducive to reducing the labor intensity of employees. Therefore, a modular basin beam hoisting device for commercial vehicles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular beam hoisting device for commercial vehicles, comprising:

[0007] A first side plate, a second side plate is provided on one side of the first side plate, a base plate is fixedly connected to the middle of the lower end of the first side plate and the second side plate by bolts, and a vertical plate is fixedly connected to the rear end of the first side plate and the second side plate by bolts to form a hoisting structure. A first polyurethane block is provided in the middle of the first side plate and the second side plate, and a second polyurethane block is provided on one side of the first side plate and the second side plate to increase the contact surface between the tooling and the pot beam assembly.

[0008] In one possible design, the front end of the first side plate is provided with a first flat hook, and the front end of the second side plate is provided with a second flat hook, so as to facilitate the adjustment of the angle between the basin beam and the ground. The front end of the lower part of the first side plate and the second side plate is provided with a first reinforcing pin. Both sides of the first reinforcing pin pass through the first side plate and the second side plate and are fixedly connected by nuts to reinforce the first flat hook and the second flat hook.

[0009] In one possible design, a first arc-shaped lifting groove is provided on both sides of the lower end of the first side plate, and a second arc-shaped lifting groove is provided on both sides of the lower end of the second side plate, for the tooling to be fully fitted with the pot beam assembly.

[0010] In one possible design, the upper ends of the first and second side plates are rotatably connected to a connecting pin for adjusting the lifting according to the lifting center of gravity. The two sides of the connecting pin pass through the first and second side plates and are fixed by nuts. The front end of the connecting pin is fixedly connected to a lifting ring for matching the lifting equipment.

[0011] In one possible design, stepped countersunk holes are provided on both sides of the first polyurethane block and the second polyurethane block, and the first polyurethane block and the second polyurethane block are respectively fixedly connected to the first side plate and the second side plate by bolts.

[0012] In one possible design, a second reinforcing pin is provided at the lower rear end of the first and second side plates. Both sides of the second reinforcing pin pass through the first and second side plates and are fixedly connected by nuts to reinforce the bottom of the hoisting structure. A third reinforcing pin is provided at the upper end of the first and second side plates. Both sides of the third reinforcing pin pass through the first and second side plates and are fixedly connected by nuts to reinforce the upper part of the hoisting structure.

[0013] In this application, after the modular assembly of the basin beam is completed, the lifting ring of the modular basin beam hoisting device is suspended on the KBK, and the hook structure is hoisted at the middle beam of the basin beam for modular basin beam hoisting assembly. The first side plate and the second side plate are part of the main frame of the hoisting device, adopting a large-span integrated hook design with simple processing technology. The bottom adopts an arc-shaped lifting groove, and the tooling is completely fitted with the basin beam assembly to ensure hoisting stability. A flat hook is added to the bottom to facilitate adjustment of the angle between the basin beam and the ground for easy lifting. The bottom plate and the vertical plate adopt a hollow structure in the middle, which reduces weight and meets the overall rigidity of the hoisting device. They are connected to the first side plate and the second side plate with bolts. The first polyurethane block and the second polyurethane block are fixed to the first side plate and the second side plate with bolts. The contact surface with the basin beam assembly is protected by polyurethane blocks to ensure the appearance quality of the components.

[0014] In this utility model, a modular basin beam hoisting device for commercial vehicles is described. This tooling is suitable for tractor trucks and dump trucks equipped with basin beams by a certain OEM. After the basin beam, front spring and rear support are assembled separately, hoisting and assembly can be carried out, which can reduce the labor intensity of employees and eliminate heavy physical work. By adopting a large-span integrated hook design, the processing technology is simple; the bottom adopts an arc-shaped hoisting groove, and the tooling is completely fitted with the basin beam assembly to ensure hoisting stability.

[0015] In this utility model, a modular basin beam lifting device for commercial vehicles is provided. By adding a flat structural hook at the bottom, the angle between the basin beam and the ground can be easily adjusted for convenient lifting. The contact surface between the tooling and the basin beam assembly is protected by polyurethane blocks to ensure the appearance quality of the components. The support surface of the polyurethane blocks has stepped countersunk holes, which are sturdy and durable, and solve the problems of damage and inconvenient disassembly. The setting of the first, second and third reinforcing pins effectively improves the stability of the lifting device structure. Attached Figure Description
