[0053] See also Figure 1-Figure 9 .

[0054] Some embodiments of the present application disclose a preassembly tool suitable for preassembly of a suspension frame support arm 4, a suspension electromagnet and a guide electromagnet.

[0055] The pre-assembly tooling disclosed in the present application includes a hoisting tooling and a fixing tooling 2, wherein the hoisting tooling is used to hoist the suspension frame bracket 4, and the suspension electromagnet and the guide electromagnet are pre-assembled with the hoisted suspension frame bracket 4;

[0056] The fixing fixture 2 is used to fix the whole body formed by the suspension frame support arm 4, the suspension electromagnet and the guide electromagnet after pre-assembly, so as to ensure that the size of the whole body formed after pre-assembly meets the requirements of the suspension frame crossbeam installation.

[0057] Specifically, the lifting tooling includes a lifting beam 11 and a support column 12. The lifting beam 11 can be mounted with a suspension frame support arm 4, and the suspension frame support arm 4 is in a vertical state on the lifting beam 11; the support column 12 is connected to the lifting beam 11 and is used to support the lifting beam 11. The height of the support column 12 is greater than the height of the suspension frame support arm 4, so that the distance between the lifting beam 11 and the ground is greater than the height of the suspension frame support arm 4.

[0058] The suspension frame support arm 4 is hoisted on the hoisting crossbeam 11 and pre-assembled with the suspension electromagnet and the guide electromagnet, and the suspension frame support arm 4, the suspension electromagnet and the guide electromagnet pre-assembled as a whole are still hoisted on the hoisting tooling, and the pre-assembled whole is in a vertical state.

[0059] The fixing fixture 2 is used to fix the whole body formed after pre-assembly to ensure the size of the whole body formed after pre-assembly.

[0060] Specifically, the fixing tool 2 includes a support arm fixing plate 21 and a supporting beam 22. The number of the support arm fixing plates 21 is equal to the number of the suspension frame support arms 4, and the support arm fixing plates 21 are connected to the suspension frame support arms 4 one by one; the supporting beam 22 is connected to the support arm fixing plate 21 for fixing the support arm fixing plate 21, and a forklift sleeve 23 that can cooperate with a forklift is provided on the supporting beam 22 so that the forklift can drive the supporting beam 22 to rise and fall vertically.

[0061] The fixing tool 2 is used to fix and support the pre-assembled whole, ensuring the size of the pre-assembled whole during the connection and disassembly process with the suspension frame crossbeam. At the same time, during transportation and storage, the pre-assembled whole also needs to be fixed and supported by the fixing tool 2 to reduce the difficulty of storage and transportation of the pre-assembled whole.

[0062] It should be noted here that the suspension frame support arm 4 is in a vertical state on the hoisting fixture, which is the position state of the suspension frame support arm 4 when connected to the suspension frame cross beam. The state of the whole formed by the suspension electromagnet and the guide electromagnet pre-assembled with the suspension frame support arm 4 is still the position state when connected to the suspension frame cross beam. When the whole formed by the pre-assembly is connected to the suspension frame cross beam in the later stage, it is not necessary to adjust the whole formed by the pre-assembly, thereby reducing the difficulty of connecting the whole formed by the pre-assembly with the suspension frame cross beam.

[0063] When it is necessary to perform separate maintenance on the electromagnet (here, electromagnet is the abbreviation of the suspension electromagnet and the guide electromagnet), the fixed tooling 2 is connected to the pre-assembled whole, and then the fixed tooling 2 is lifted by a forklift, and the connection structure between the pre-assembled whole and the suspension frame crossbeam is removed. Finally, the pre-assembled whole and the fixed tooling 2 are driven down by the forklift, and the fixed tooling 2 keeps the pre-assembled whole in a vertical state, so that the staff can perform separate maintenance on the electromagnet (here, electromagnet is the abbreviation of the suspension electromagnet and the guide electromagnet), while reducing the difficulty of maintenance.

[0064] The support column 12 may be a single column or a combination of multiple columns.

The support plate 121 can increase the contact area between the support column 12 and the ground. The lower end of the vertical beam 122 is connected to the support plate 121, and the upper end of the vertical beam 122 is connected to the lifting beam 11.

[0066] The number of the vertical beams 122 is at least two. Specifically, the number of the vertical beams 122 may be two or more than two.

Preferably, the plane where the two vertical beams 122 are located is perpendicular to the support plate 121.

[0068] In some other embodiments of the present application, the number of the vertical beams 122 is three or more, the vertical beams 122 are arranged obliquely relative to the support plate 121, the three vertical beams 122 and the support plate 121 form a triangular pyramid structure, or more than three vertical beams 122 and the support plate 121 form a polygonal pyramid structure.

Preferably, the plane where the vertical beams 122 are located is perpendicular to the support plate 121.

[0071] In some embodiments of the present application, the support plate 121 is a flat plate. Preferably, the support plate 121 is connected to the vertical beam 122 by welding.

[0072] In order to further optimize the above technical solution, the support column 12 disclosed in the present application further includes a reinforcing beam 123 , and both ends of the reinforcing beam 123 are respectively connected to two adjacent vertical beams 122 .

The second mounting hole corresponds to the position of the first mounting hole. The end mounting plate 31 and the top mounting plate 32 are connected by bolts that cooperate with the first mounting hole and the second mounting hole.

[0078] The end mounting plate 31 and the top mounting plate 32 are not limited to being connected by bolts, but may also be connected by welding.

[0079] In this embodiment, the connection area between the hoisting beam 11 and the support column 12 is increased by the end mounting plate 31 and the top mounting plate 32 , thereby enhancing the stability of the connection between the hoisting beam 11 and the support column 12 .

[0080] Preferably, the end mounting plate 31 is welded to the hoisting beam 11 , and the top mounting plate 32 is welded to the support column 12 .

[0082] Specifically, the support arm connecting plate 111 is connected to the suspension frame support arm 4 by bolts, which can reduce the difficulty of installing and disassembling the suspension frame support arm 4 on the lifting beam 11.

After installation, the fixing tool 2 and the suspension frame support arm 4 are located on the same side of the lifting beam 11 .

[0084] In order to meet the assembly requirements of electromagnets at different positions, four bracket connecting plates 111 are provided on the hoisting beam 11. Specifically, the end electromagnets use three bracket connecting plates 111, and the remaining electromagnets use two bracket connecting plates 111. The installation position of the bracket connecting plates 111 can be selected according to different types of electromagnets.

[0085] Positioning holes and threaded holes are processed on the support arm connecting plate 111, and the suspension frame support arm 4 can be installed at the position corresponding to the support arm connecting plate 111, which saves the time of measuring and positioning and improves the tooling efficiency of electromagnet assembly.

[0086] In order to enhance the strength of the lifting beam 11, the present application provides side reinforcement ribs 112 and top reinforcement ribs 113 on the lifting beam 11, wherein the top reinforcement rib 113 and the end mounting plate 31 are arranged relative to each other on the lifting beam 11, so as to enhance the strength of the lifting beam 11 along its own length direction; the side reinforcement ribs 112 are located on the side wall of the lifting beam 11 and are perpendicular to the top reinforcement ribs 113, the upper ends of the side reinforcement ribs 112 are connected to the top reinforcement ribs 113, and the side reinforcement ribs 112 are connected to the lifting beam 11, so as to further enhance the strength of the lifting beam 11.

[0087] like Figure 4 As shown, the bracket fixing plate 21 is a T-shaped plate, which includes a vertical plate 211 and a bottom plate 212.

[0088] The vertical plate 211 is provided with a support arm fixing hole, and the suspension frame support arm 4 is fixed to the support arm fixing plate 21 at its lower portion through the support arm fixing hole and fasteners.

[0089] In the present application, the vertical plate 211 is perpendicular to the bottom plate 212 and the supporting beam 22 .
