Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution for a non-standard suspended basket pulley suspension device for a shallow circular warehouse with a sloping roof: including a parapet wall slope 1, a shallow circular warehouse trestle column 2, a connecting base plate 3, a suspended basket working steel wire rope 4, a U-shaped rope clamp 5, a runway hole 6, an M12 expansion nut 7, a fixed side plate 8, a main pin 9, a secondary pin 10, a pulley body 11, a U-shaped rope clamp nut 12, and a U-shaped rope clamp groove 13.

[0027] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 4As shown, the connecting base plate 3 is evenly spaced on the lower end face of the parapet wall slope 1, and six track holes 6 are arrayed on the connecting base plate 3. A fixing side plate 8 is vertically fixed to the lower end face of the connecting base plate 3. The width, length, and thickness of the connecting base plate 3 are 200mm, 300mm, and 8mm, respectively. The outer surface of the connecting base plate 3 is hot-dip galvanized. The width and length of the track holes 6 on the connecting base plate 3 are 17mm and 56mm, respectively. The main pin 9 and the auxiliary pin 10 are grade 8.8 Φ20mm and grade 8.8 Φ10mm, respectively. The diameter and width of the pulley body 11 mounted on the main pin 9 are 44mm and 22mm, respectively, and the rope groove of the pulley body 11 is V-shaped. Before installation, the structure of the parapet wall slope 1 is inspected. The concrete strength must meet the design requirements. The perimeter of the parapet wall slope 1 is calculated. The installation pulley head suspension device is arranged and laid out on site. The layout position is checked. After it is correct, holes are drilled and installed according to the design hole spacing of the device and tightened with nuts. During this period, 1% of the expansion bolts are randomly sampled on site, but no less than 3, for testing. The pull-out force is not less than 6KN and the torque is not less than 40N·m. The structure is observed to have no obvious damage or cracks. Then, the connecting base plate 3 is attached to the outer surface of the parapet wall slope 1, and the M12 expansion nut 7 is inserted through the runway hole 6 to facilitate the installation of the connecting base plate 3 on the parapet wall slope 1.

[0028] Combination Figure 1 , Figure 2 and Figure 3 As shown, the working wire rope 4 of the suspended platform passes sequentially through the outer surfaces of three pulley bodies 11 and is wound and connected to the outer surface of the shallow circular barn trestle column 2. The cross-sectional diameter of the working wire rope 4 is less than twice the internal spacing of the U-shaped rope clamps 13. Four U-shaped rope clamps 13 are evenly spaced on the outer surface of the working wire rope 4. These U-shaped rope clamps 13, through U-shaped rope clamp plates 5 and U-shaped rope clamp nuts 12, form a disassembly structure on the working wire rope 4. This allows for the assembly of the suspended platform, installation of the hoist and safety lock on a stable ground. The working wire rope 4, after passing through the pulley bodies 11, winds once around the parapet wall slope 1 and the shallow circular barn trestle column 2, and is secured by the four U-shaped rope clamps 13. The U-shaped rope clamp groove 13 is positioned opposite the end of the working wire rope 4 of the suspended platform, and the direction is consistent. The U-shaped rope clamp groove 13 is clamped sequentially starting from the hoisting point, and the working wire rope 4 of the suspended platform is slightly arched between the last rope clamp and the previous rope clamp. When the U-shaped rope clamp groove 13 is tightened with the U-shaped rope clamp nut 12, the working wire rope 4 of the suspended platform is flattened to 1 / 2 to 1 / 3 of its diameter. After the exterior facade paint of the parapet wall slope 1 is completed and the suspension head device is removed, the M12 expansion nut 7 is cut and sealed with crack-resistant mortar to prevent long-term soaking by rainwater and rust water from the rusting of the working wire rope 4 of the suspended platform from polluting the exterior facade. This is the working process of the non-standard suspended platform pulley suspension head device for the shallow round warehouse sloping roof.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
