[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution for an electric drive assembly device for a climbing boom: it includes a support plate 10, on which a protective mechanism is provided. The protective mechanism includes connecting strips 11 at both ends of the support plate 10. A protective frame 12 is provided at the upper end of the support plate 10 and the connecting strips 11. Four first grooves 14 are provided at the upper end of the protective frame 12. Spring columns 15 are fixedly connected inside each of the four first grooves 14. The movable ends of the four spring columns 15 are fixedly connected to the upper ends of two connecting strips 11 respectively. Limiting grooves 16 are provided on the contact surfaces of the two connecting strips 11 and the support plate 10. Rotating columns 17 are fixedly connected at both ends of the support plate 10. The rotating columns 17 are located inside the limiting grooves 16. The height of the protective frame 12 is slightly higher than the height of the overall components on the support plate 10 to avoid external collisions and achieve a good protective effect. When the connecting strips 11 and the support plate 10 are away from the protective frame 12, the support plate 10 can rotate based on the connecting strips 11, and the components installed on its surface will not form an obstruction.

[0019] Sealing gaskets 18 are provided on the contact surfaces of the connecting strip 11, the support plate 10 and the protective frame 12. Sealing gaskets 18 are also provided on the contact surfaces of the two connecting strips 11 and the support plate 10. By setting multiple sealing gaskets 18, the waterproof effect of the overall structure can be improved, and water flow can be prevented from entering the device during use.

[0020] The connecting strip 11 has a limiting hole 19, and the protective frame 12 has a mounting hole 13. The diameter of the limiting hole 19 is slightly larger than the diameter of the mounting hole 13. When the entire assembly needs to be installed through the mounting hole 13, the mounting screw can first be passed through the limiting hole 19 and contact the mounting hole 13 before tightening. During the tightening process, the limiting hole 19 limits the mounting screw, ensuring that it will fall off or shift during rotation, thus further facilitating the installation of the assembly.

[0021] The upper end of the support plate 10 is fixedly connected to a travel motor controller 1, which is connected to an external travel motor through three terminals: U, V, and W. The upper end of the support plate 10 is fixedly connected to an oil pump motor controller 2, which is connected to an external oil pump motor through three terminals: U, V, and W.

[0022] A first power relay 3 and a second power relay 4 are fixedly connected to the upper end of the support plate 10. A fuse 9 is provided on the travel motor controller 1. The first power relay 3 is connected to the fuse 9 through the first copper strip 61. The second power relay 4 is connected to the oil pump motor controller 2 through the second copper strip 62. The activation or deactivation of the first power relay 3 determines whether the travel motor controller 1 has power. Power enters from the positive terminal 8 of the power supply, passes through the first power relay 3, the first copper strip 61, and the fuse 9, and reaches the B+ terminal of the travel motor controller 1. The activation or deactivation of the second power relay 4 determines whether the oil pump motor controller 2 has power. Power enters from the positive terminal 8 of the power supply, passes through the second power relay 4, and reaches the B+ terminal of the oil pump motor controller 2 through the second copper strip 62.

[0023] The upper end of the support plate 10 is fixedly connected to the negative terminal 7 and the positive terminal 8. The negative terminal 7 is connected to the travel motor controller 1 and the oil pump motor controller 2 through the third copper bar 63 and the fourth copper bar 64 respectively. The positive terminal 8 is connected to the fifth copper bar 65. The negative terminal (ground) of the power supply enters from the negative terminal 7, passes through the third copper bar 63 and the fourth copper bar 64 and reaches the B- of the travel motor controller 1 and the oil pump motor controller 2 respectively.

[0024] The support plate 10 is made of aluminum and serves to fix and support all components of the entire assembly.

[0025] The working principle of this utility model is as follows: The entire assembly can be installed through the mounting hole 13 and the matching fixing screws. The walking motor controller 1 is connected to the external walking motor through the three terminals U, V, and W. The oil pump motor controller 2 is connected to the external oil pump motor through the three terminals U, V, and W. The engagement or disengagement of the first power relay 3 determines whether the walking motor controller 1 has power. Power enters from the positive terminal 8, passes through the first power relay 3, the first copper strip 61, and the fuse 9, reaching the B+ terminal of the walking motor controller 1. The engagement or disengagement of the second power relay 4 determines whether the oil pump motor controller 2 has power. Power enters from the positive terminal 8, passes through the second power relay 4, and the second copper strip 62, reaching the B+ terminal of the oil pump motor controller 2. The negative terminal (ground) of the power supply enters from the negative terminal 7, passes through the third copper strip 63 and the fourth copper strip 64, and reaches the walking motor controller 1 respectively. The B- of the oil pump motor controller 2, through the above-mentioned electrical connection, can ensure the normal use of the assembly. When it is necessary to repair the components on the support plate 10, it is only necessary to pull the support plate 10 and the connecting strip 11 downward based on the protective frame 12 and pull the spring column 15. When the support plate 10 and the connecting strip 11 move to the outermost position, the support plate 10 can be rotated based on the limit groove 16 through the rotating column 17 until all the components on the support plate 10 are exposed, and repair can begin. There is no need to disassemble the assembly during the repair process, saving time and effort.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
