Description

A rotary transfer platform for large-load and large-size components Technical Field

[0001] This utility model relates to the field of steel structure processing and manufacturing technology, and in particular to a rotating and transferring platform for large-load, large-size components. Background Technology

[0002] In steel structure production workshops, the transfer of raw materials and large components typically relies on rail-mounted transfer flatbed trucks in conjunction with hoisting equipment. However, large-load, large-size components have significant inertia, making it difficult to precisely control their orientation during hoisting or lowering. This can easily lead to collisions with the transfer flatbed truck, causing scratches, deformation, and other damage to the component's surface. This not only affects product quality but also increases repair costs and time. Existing transfer equipment is mostly a fixed platform without rotation adjustment capabilities, failing to address the compatibility issue between the hoisting direction and the transfer platform. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model discloses a large-load, large-size component rotation and transfer platform.

[0004] The specific technical solution is as follows:

[0005] A large-load, large-size component rotating transfer platform includes a base assembly and a rotating platform assembly. The base assembly is installed at a designated position on a workshop rail transfer flatbed to provide fixed support and a rotation reference. The rotating platform assembly is connected to the base assembly to achieve centering and assist in smooth rotation.

[0006] The base assembly includes a base, a slide rail, and a pivot pin. The base is provided with an annular slide rail, and the pivot pin is installed vertically upward at the center of the annular slide rail.

[0007] The rotating platform assembly includes multiple sets of supporting pulleys, pulley support arms, platform support bearings, and a circular rotating platform. The multiple sets of supporting pulleys are evenly and circumferentially installed on the bottom surface of the rotating platform through the pulley support arms. The platform support bearings are fitted with axle pins to form a centering rotating pair, which limits the rotation center. The supporting pulleys are embedded in the slide rails to form a sliding support pair, which achieves sliding fit to bear the load and assist rotation. The rotating platform carries large-load, large-size components to be transferred.

[0008] One end of the pulley support arm is fixed to the bottom surface of the rotating platform, and the other end is rotatably mounted with a support pulley.

[0009] The slide is concentric with the rotating platform.

[0010] The rotary transfer platform is installed as a whole on a rail transfer flatbed vehicle in the steel structure production workshop.

[0011] The pulley support arm and the rotating platform are integrally formed.

[0012] The supporting pulley is made of wear-resistant alloy steel.

[0013] The slide is a hardened circular track, and the clearance between the slide and the supporting pulley is controlled within 0.5mm.

[0014] The platform support bearing is a self-aligning roller bearing.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] This utility model provides a rotating transfer platform for large-load, large-size components. Through the directional rotation adjustment function of the rotating platform, the direction of the component during hoisting is precisely matched with the hoisting equipment to achieve synchronization, avoiding collisions and scratches caused by inertia, effectively protecting the surface quality of the component, and improving the safety and efficiency of transfer and hoisting.

[0017] In addition, the integrated base assembly and rotating platform assembly enhance the overall structural strength, and the cooperation between the support pulleys and the annular slide can stably bear large loads, making it suitable for the transfer needs of large steel structure components (≥50 tons). It can be installed on existing rail transfer flatbeds without requiring large-scale modifications to the original equipment in the workshop, making it highly applicable and quickly promoted for application.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0023] Figure 1 is a three-dimensional structural diagram of the large-load, large-size component rotating transfer platform of this utility model; Figure 2 is a structural diagram of the supporting pulley, pulley support arm, and slide rail of this utility model; Figure 3 is a structural diagram of the centering position of the base assembly and rotating platform assembly of this utility model, as shown in the figures:

[0024] This utility model relates to a large-load, large-size component rotary transfer platform. The rotary transfer platform is installed as a whole on a rail transfer flatbed in a steel structure production workshop, and includes a base assembly and a rotary platform assembly.

[0025] The base assembly is installed at a designated position on the workshop rail transfer flatbed to provide fixed support and rotation reference. The base assembly includes a base 1, a slide 2, and a pin 3. The base 1 is provided with an annular slide 2, and the pin 3 is installed vertically upward at the center of the annular slide 2. The slide 2 is a hardened annular track, and the clearance between it and the support pulley 4 is controlled within 0.5mm to ensure smooth rotation and no radial wobble.

[0026] The rotating platform assembly connects with the base assembly to achieve centering and assist the rotating platform 7 in smooth rotation. The rotating platform assembly includes multiple sets of support pulleys 4, pulley support arms 5, platform support bearings 6, and a circular rotating platform 7. The multiple sets of support pulleys 4 are evenly and circumferentially installed on the bottom surface of the rotating platform 7 via pulley support arms 5. One end of the pulley support arm 5 is integrally formed and fixed to the bottom surface of the rotating platform 7, while the other end is rotatably mounted with the support pulley 4. The support pulleys 4 are made of wear-resistant alloy steel and can withstand long-term heavy load sliding wear. The platform support bearing 6 is a self-aligning roller bearing, which, when fitted with a shaft pin 3, can compensate for installation errors and withstand axial loads, forming a centering rotating pair to achieve rotation center limit. The support pulleys 4 are embedded in the slide rail 2 to form a sliding support pair, achieving sliding fit to bear loads and assist rotation. The rotating platform 7 carries large-load, large-size components to be transferred, and the rotating platform 7 is concentric with the slide rail 2.

[0027] During installation, assemble the base assembly (including base 1, slide 2, and pin 3) and fix it in the designated position on the workshop rail transfer flatbed, ensuring that pin 3 is vertically upward. Assemble the rotating platform assembly (including rotating platform 7, platform support bearing 6, pulley support arm 5, and support pulley 4), and then connect the rotating platform assembly with the base assembly, so that the platform support bearing 6 fits into the base pin 3 to form a centering rotating pair, thereby limiting the rotation center. At the same time, embed the support pulley 4 into the base slide 2 to form a sliding support pair, thereby achieving a sliding fit to bear the load and assist rotation, thus completing the overall assembly.

[0028] When in use, after placing the large-load, large-size component to be transferred on the rotating platform 7, the transfer flatbed trolley moves along the workshop track to the hoisting position; when the hoisting equipment hooks up, the rotating platform 7 is manually or electrically driven to rotate according to the hoisting direction, so that the hoisting direction of the component is completely aligned with the working direction of the hoisting equipment; during the hoisting or lowering process, the rotating platform 7 can be adjusted synchronously with the component to avoid collision between the component and the transfer flatbed trolley.
