[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] refer to Figure 1 and Figure 2 This utility model provides a wheel assembly disassembly device for a sintering trolley, referenced in [reference]. Figure 1 , Figure 2 and Figure 3This utility model provides a wheel assembly disassembly device for a sintering trolley. The sintering trolley 1 includes a trolley frame 11 and wheel assemblies 12 arranged on both sides of the trolley frame 11. The wheel assembly 12 includes a wheel axle 121 and trolley wheels 122 mounted on the wheel axle 121. Multiple bottom beams 2 are evenly arranged on the trolley frame 11 along its transverse direction.
[0025] refer to Figures 1-4 The wheel assembly disassembly device includes a worktable 3, a pressing member 4 disposed on the upper end face of the worktable 3, and a snap-fit fixing member 5 disposed on the lower end face of the worktable 3. The snap-fit fixing member 5 is used to install the worktable 3 on the base beam 2. The snap-fit fixing member 5 includes a first snap-fit plate 51 and a second snap-fit plate 52. The first snap-fit plate 51, the second snap-fit plate 52 and the snap-fit groove formed by the lower end face of the worktable 3 engage with the base beam 2. When installing the wheel assembly disassembly device, it can be directly snapped onto the base beam 2 through the snap-fit groove. The operation is simple and convenient, and it can achieve rapid installation and disassembly. Friction protrusions 6 are provided on the opposite sides of the first snap-fit plate 51 and the second snap-fit plate 52. The friction protrusions 6 are made of rubber material, which can increase the friction between the first snap-fit plate 51, the second snap-fit plate 52 and the base beam 2, thereby improving the firmness. The number of snap-fit fasteners 5 is at least two. The distance between two adjacent snap-fit fasteners 5 is the same as the distance between two adjacent bottom beams 2. The snap-fit fasteners 5 are used for snap-fit fastening, which is relatively stable.
[0026] refer to Figures 1-4 The top pressure component 4 is a hydraulic jack. Based on the actual setup of the bottom beam 2 of the sintering trolley 1, the distance between the left lateral side of the wheel axle 121 and its adjacent bottom beam 2 is relatively large. Therefore, to ensure the hydraulic jack can push the wheel axle 121, it is positioned on one side of the worktable 3. The hydraulic jack is detachably mounted on the worktable 3 via a support base 7. Support bases 7 of different heights can be replaced according to the actual working conditions to ensure that the axis of the hydraulic jack and the axis of the wheel axle 121 are on the same horizontal straight line.
[0027] refer to Figure 4 and Figure 5 The support base 7 includes an upper top base 71 and a lower base 72. The hydraulic jack is fixed to the upper end face of the upper top base 71 by a locking block 73. The area of the lower base 72 is larger than that of the upper top base 71. A recessed groove 8 is provided at the position corresponding to the lower base 72 on the upper end face of the worktable 3. The bottom of the lower base 72 is installed in the recessed groove 8 and fixed to the worktable 3 by bolts 9. When the trolley assembly is pushed by the hydraulic jack, the recessed groove 8 can play a limiting role, preventing the support base 7 from moving when subjected to reaction force, and further improving its stability.
[0028] refer to Figure 3A baffle 10 is also provided on the workbench 3, and the end of the main body of the hydraulic jack is detachably connected to the baffle 10. The baffle 10 further blocks and limits the hydraulic jack, improving its stability. Reinforcing ribs 20 are provided on the opposite sides of the first snap-fit plate 51 and the second snap-fit plate 52, and reinforcing ribs 20 are also provided on the side of the baffle 10 away from the top pressing member 4, which further improves the overall strength.
[0029] refer to Figures 1-5 The specific working principle is as follows: When disassembling the trolley assembly, the wheel assembly disassembly device is directly clamped onto the bottom beam 2. At this time, the ejector shaft of the hydraulic jack and the wheel axle 121 are kept in a straight line. The wheel axle and the bushing are interference fit. During disassembly, the bushing is heated at high temperature, while the shaft is not heated. After the temperature difference between the shaft and the bushing is greater than the interference gap, the hydraulic jack starts to work, thereby ejecting the wheel axle 121 on which the trolley wheel 122 is installed, thus realizing disassembly.
[0030] In summary, the trolley assembly disassembly device of this structure can be quickly installed on the bottom beam 2. It is simple and convenient to operate. The trolley assembly can be quickly pushed out by hydraulic jacks, which greatly improves the work efficiency of maintenance personnel. Moreover, it is not easy to damage the sintering trolley 1 during disassembly and installation.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
