Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Please see Figure 1 , Figure 2 and Figure 3A quick and easy-to-assemble integrated cast hoist trolley includes an integrated cast hoist trolley 1, an integrated cast rail trolley 2, a crossbeam 3, and a longitudinal beam 4. The integrated cast hoist trolley 1 travels on the crossbeam 3, the longitudinal beam 4 is fixed to the integrated cast hoist trolley 1, and the integrated cast rail trolley 2 travels on the longitudinal beam 4. The integrated cast hoist trolley 1 includes a novel rigid KBK beam head 11. The novel rigid KBK beam head 11 and the rail trolley beam head 21 are respectively manufactured using integrated die casting and CNC processes. The integrated forging process can achieve a more robust metal grain structure. The optimization improves the mechanical properties of the parts, such as strength and toughness. Furthermore, the forging process allows for better control of material flow, reducing waste and increasing utilization. The combination of integral forging and CNC machining also minimizes surface defects in the new rigid KBK beam head 11, improving its surface quality. Only forging can achieve high precision and consistency in product quality, ensuring product stability. High-precision integral forging combined with high-precision CNC machining minimizes overall product error. The upper end of the new rigid KBK beam head 11... Multiple hoist trolley bearing wheels 12 are installed. The hoist trolley bearing wheels 12 and the track trolley bearing wheels 22 are high-strength nylon wheels manufactured by injection molding, enabling them to bear heavy loads. Two hoist trolley guide wheels 14 are symmetrically arranged on the upper end of the integrally cast hoist trolley 1. A fixing member 15 is fixed to the lower end of the novel rigid KBK beam head 11, and a clamping assembly is fixed to the novel rigid KBK beam head 11. The integrally cast track trolley 2 includes a track trolley beam head 21, with multiple track trolley bearing wheels 22 arranged on its upper end. The upper center of the 1 is rotatably connected to the guide wheel 23 of the trolley. The trolley beam head 21 is inverted Y-shaped. Multiple reinforcing plates 25 are fixed at the lower end of the trolley beam head 21. The lower end of the trolley beam head 21 is provided with mounting holes 24. The hoist trolley guide wheel 14 and the guide accessory 13 guide the integrally cast hoist trolley 1 and the integrally cast trolley 2 respectively, so that the integrally cast hoist trolley 1 can move smoothly in the crossbeam 3 and the integrally cast trolley 2 can move smoothly in the longitudinal beam 4. By adding reinforcing plates 25 in the trolley beam head 21, the overall rigidity of the trolley beam head 21 is increased, so that it can bear a heavier weight.

[0024] Furthermore, the reduction of welding steps compared to traditional methods in one-piece forging prevents the product itself from deforming due to welding.

[0025] Please see Figure 2 , Figure 3 and Figure 4The novel rigid KBK beam head 11 has guide attachments 13 detachably connected to its left and right ends. The hoist trolley guide wheel 14 is rotatably connected to the guide attachment 13. The hoist trolley bearing wheel 12 is located between the two guide attachments 13. The novel rigid KBK beam head 11 has attachment mounting holes at its left and right ends. The attachment mounting holes in the novel rigid KBK beam head 11 adopt a standardized design, which improves the versatility of the modular design for attachment installation, replacement, and maintenance. The fixing member 15 is U-shaped, with its front and rear ends... Multiple fastening bolts 16 are provided. The open end of the fixing member 15 is bent inward with a folded edge. A reinforcing rib is fixed at the connection between the fixing member 15 and the new rigid KBK beam head 11. The longitudinal beam 4 is installed in the fixing member 15 of the integrally cast hoist trolley 1 for snap-fit. After completion, the fastening bolts 16 are tightened, and the fastening bolts 16 will clamp and fix the longitudinal beam 4 to prevent the longitudinal beam 4 from slipping out of the fastening bolts 16. At the same time, a reinforcing rib is added at the connection between the fixing member 15 and the new rigid KBK beam head 11 to ensure the firmness of the connection between the fixing member 15 and the new rigid KBK beam head 11.

[0026] Please see Figure 3 , Figure 4 and Figure 5 The clamping assembly includes a fixing plate 17, which is detachably connected to the new rigid KBK beam head 11. A gasket 171 is provided at the lower end of the fixing plate 17, and an anti-slip support plate 172 is provided at the lower end of the gasket 171. A nut 174 and a square neck bolt 173 are provided on the fixing plate 17. The gasket 171 and the anti-slip support plate 172 are connected to the fixing plate 17 via the nut 174 and the square neck bolt 173. The fixing plate 17 is inverted T-shaped, with its lower end bent upwards at a folded edge. The anti-slip support plate 172 is arc-shaped. The upper end of the anti-slip support plate 172 and the gasket 171 are connected to the fixing plate 17. The lower end of 1 is provided with anti-slip texture. The fixing plate 17 and the gasket 171 are fixed with square through holes for the square neck bolt 173 to pass through. The clamping assembly is used to clamp the cable so that the integral cast hoist trolley 1 moves with the cable. When fixing, the cable is placed on the anti-slip support plate 172, and then the square neck bolt 173 is passed through the fixing plate 17 and the gasket 171. The square neck bolt 173 is tightened by the nut 174 so that the gasket 171 and the anti-slip support plate 172 clamp and fix the cable. After the cable is fixed, the fixing plate 17 is fixed to the new rigid KBK beam head 11 by existing technical means.

[0027] This device requires the use of an external traveling trolley and an electric hoist. The traveling trolley is connected to the new rigid KBK beam head 11 to facilitate the movement of the integrated casting hoist trolley 1. At the same time, the electric hoist is fixed in the mounting hole 24 of the traveling trolley beam head 21. In use, the traveling trolley is controlled to move the integrated casting hoist trolley 1 to the designated position. Then, the integrated casting traveling trolley 2 is moved to the position above the item. The item is then lifted by the electric hoist and moved to the designated position by the integrated casting hoist trolley 1 and the integrated casting traveling trolley 2.
