Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, a crane frame that is easy to disassemble in the figure includes a pulley 1 and a folding mechanism arranged on the top of the pulley 1, and the folding mechanism includes a telescopic and supporting assembly;

[0025] The telescopic assembly includes a cylindrical groove 5, a telescopic connecting strip 6, a short connecting rod 7, a long connecting rod 8 and a stair platform 10. A cylindrical groove 5 is arranged above the pulley 1. One end of the cylindrical groove 5 is slidably connected to the telescopic connecting strip 6. One end of the telescopic connecting strip 6 is fixedly connected to the short connecting rod 7. One end of the short connecting rod 7 is rotatably connected to the stair platform 10. The side wall of the stair platform 10 is rotatably connected to the long connecting rod 8.

[0026] The supporting assembly includes a first fixed rod 2, a vertical connecting rod 3, a connecting pile 4 and a fixed column 9. The first fixed rod 2 is provided at one end of the stair platform 10, the surface of the first fixed rod 2 is fixedly connected to the vertical connecting rod 3, the surface of the first fixed rod 2 is fixedly connected to the connecting pile 4, and the side wall of the vertical connecting rod 3 is located at one end of the stair platform 10 and is fixedly connected to the fixing column 9.

[0027] Among them, Figure 3 As shown, the long connecting rod 8 forms a folding structure with the stair deck 10 through the cylindrical groove 5 and the telescopic connecting strip 6. This is beneficial when a crane fails or when one wants to inspect, repair or disassemble the crane on the main beam 14. The telescopic connecting strip 6 can be used to perform telescopic movement in the cylindrical groove 5, thereby driving the long connecting rod 8 and the long connecting rod 8 to perform folding movement. The operation of the folding stairs can help realize the telescopic and folding movement of the stairs for disassembly of the crane.

[0028] Among them, Figure 3 As shown, two groups of vertical connecting rods 3 are provided, and the positions of the two groups of vertical connecting rods 3 are symmetrically distributed with respect to the first fixed rod 2, which is beneficial to stabilizing the folding stairs when the folding stairs are moving to prevent the folding stairs from tilting and collapsing, thereby causing casualties. Two groups of reinforcement and stability are provided to facilitate the telescopic and folding of the folding stairs, thereby stabilizing the folding stairs and avoiding casualties.

[0029] Among them, Figure 3 As shown, the fixed column 9 forms a fixed structure with the stair deck 10 through the first fixed rod 2 and the vertical connecting rod 3. The fixed column 9 is fixed to the vertical connecting rod 3 and the stair deck 10, which is beneficial to fixing the stair deck 10. If the stairs are not fixed to the frame, it is easy to shake and tilt. In order to prevent the stair deck 10 from tilting and causing casualties, connecting rods and fixing rods are provided to fix the folding stairs, thereby ensuring the safety of the folding stairs during movement.

[0030] Example 2

[0031] like Figure 1 , Figure 3 and Figure 4As shown, this embodiment further illustrates Example 1, a transverse support frame 11 is fixedly connected to the top of the pulley 1, a first support frame 12 is fixedly connected to the surface of the transverse support frame 11, a second support frame 13 is fixedly connected to the surface of the transverse support frame 11, a main beam 14 is snap-connected to the top of the first support frame 12, a first screw 15 is rotatably fixedly connected to the top of the main beam 14, a second screw 16 is fixedly connected to one end of the second support frame 13 above the main beam 14, and a hook 17 is provided at the bottom of the main beam 14.

[0032] Among them, Figure 4 As shown, four groups of first support frames 12 are provided, and the positions of the four groups of first support frames 12 are distributed in a rectangular array with respect to the outer wall of the main beam 14. The provision of four groups of first support frames 12 is beneficial to stabilizing the overall structure of the lifting crane. The four groups of first support frames 12 are all engaged and connected with the main beam 14, which not only increases the safety of the lifting crane but also reduces the difficulty of disassembling the lifting crane, thereby facilitating the disassembly of the lifting crane while increasing safety.

[0033] Among them, Figure 4 As shown, the main beam 14 forms a locking structure with the first support frame 12 through the cross support frame 11 and the first screw 15, which is beneficial for people to easily disassemble the crane when the crane is damaged or stuck. The locking structure between the main beam 14 and the first support frame 12 is not only convenient for disassembly but also has a good fixing effect. In addition, the fixing of the screws realizes the functions of fixing the crane and facilitating disassembly.

[0034] When in use: first, the folding mechanism is assembled by cooperating with the telescopic connecting strip 6, the short connecting rod 7, the long connecting rod 8 and the stair platform 10, and then the telescopic connecting strip 6 drives the short connecting rod 7 so that the long connecting rod 8 and the stair platform 10 are retracted to realize the retraction operation of the folding staircase, which is convenient for retracting the folding staircase and disassembling the lifting crane;

[0035] Finally, the main beam 14 is engaged, and the first support frame 12, the main beam 14 and the first screw 15 cooperate to assemble the engaging mechanism. The raised part of the first support frame 12 is perfectly engaged with the empty part of the main beam 14, and then the first screw 15 is used to reinforce the connection, thereby realizing the function of facilitating the disassembly of the lifting crane.
