[0031] To solve the problems in the prior art, the present application provides a device for disassembling and assembling a motor rotor of a dump truck. This device for disassembling and assembling a motor rotor of a dump truck can effectively reduce the work intensity of border inspection and maintenance and improve the efficiency of maintenance operations.

[0032] Figure 1 The structural schematic diagram of a device for disassembling and assembling a motor rotor of a dump truck provided by an embodiment of the present application is shown; Figure 2 The structural schematic diagram of a rotation adjustment mechanism and a feeding mechanism provided by an embodiment of the present application is shown.

[0033] As Figure 1-2 shown, an embodiment of the present application provides a device for disassembling and assembling a motor rotor of a dump truck, including a chassis truck 1, a lifting mechanism 2, a rotation adjustment mechanism 3, a feeding mechanism 4, and an automatic disassembly and assembly mechanism 5.

[0034] The lifting mechanism 2 is arranged on the chassis truck 1. The lifting mechanism 2 includes a lifting assembly 21 and a mounting bracket 22 arranged at the movable end of the lifting assembly 21.

[0035] The rotation adjustment mechanism 3 includes a crossbeam arm 31 rotatably connected to the mounting bracket 22 and a driving assembly 32 disposed on the crossbeam arm 31. The driving assembly 32 is used to drive the crossbeam arm 31 to rotate.

[0036] The feeding mechanism 4 is disposed on the crossbeam arm 31. The feeding mechanism 4 includes a flange 41 for fixing the motor rotor a, and the flange 41 is movable along the extending direction of the crossbeam arm 31.

[0037] The automatic disassembly and assembly mechanism 5 is disposed on the mounting bracket 22 and adjacent to the feeding mechanism 4. The automatic disassembly and assembly mechanism 5 is used to disassemble and assemble the bolts between the flange 41 and the motor rotor a.

[0038] Specifically, an air monitor and an automatic fire extinguishing system which are electrically connected are further provided on the chassis truck 1. When the air monitor measures that the smoke concentration in the air exceeds its monitoring threshold, it sends a signal to the automatic fire extinguishing system, so that the automatic fire extinguishing system is started to prevent a fire from occurring and improve safety. Specifically, both the air monitor and the automatic fire extinguishing system are conventional existing devices, and their structures will not be described in detail here.

[0039] In this application, the flange 41 and the motor rotor a are bolted and fixed by the automatic disassembly mechanism, moved to the maintenance position by the chassis truck 1, the mounting bracket is lifted by the lifting assembly 21, so as to complete the lifting of the motor rotor a. The crossbeam arm 31 is driven to swing by the rotation adjustment mechanism 3 to adjust the angle of the motor rotor a, so that the motor rotor a is aligned with the motor stator. The motor rotor a is placed into the motor stator by the feeding mechanism 4, and the bolts between the flange 41 and the motor rotor a are disassembled by the automatic disassembly mechanism, so as to complete the installation of the motor rotor a, which can effectively reduce the working intensity of border inspection and maintenance and improve the maintenance operation efficiency.

[0040] In the related art, since the border inspection drive motor supporting the dump truck weighs more than 1 ton, when the border inspection drive motor is periodically maintained, generally, the motor rotor a is hoisted by a traveling crane, and the position of the hoisted motor rotor a is manually adjusted to make the motor rotor a rotate opposite to the motor stator. Then, the disassembly and assembly maintenance of the motor rotor a is jointly completed by the cooperation of manual and traveling crane hoisting. The working efficiency is low, the working intensity is large, and it requires manual operation. There are certain safety hazards for the staff when moving the motor rotor a.

[0041] In the embodiments of the present application, the flange 41 and the motor rotor a are fixed with bolts by an automatic disassembly mechanism, moved to the maintenance position by the chassis truck 1, the mounting bracket is lifted by the lifting assembly 21 to complete the lifting of the motor rotor a, the cross beam arm 31 is driven to swing by the rotation adjustment mechanism 3 to adjust the angle of the motor rotor a, so that the motor rotor a is aligned with the motor stator, the motor rotor a is placed into the motor stator by the feeding mechanism 4, and the bolts between the flange 41 and the motor rotor a are disassembled by the automatic disassembly mechanism, thereby completing the installation of the motor rotor a. The disassembly of the motor rotor a can be operated according to the reverse process. It can effectively reduce the working intensity of border inspection and maintenance, improve the efficiency of maintenance operations, and the number of operators is reduced from multiple to two. There is no need to manually move the motor rotor a, thus improving the safety of operations.

[0042] In some embodiments, the drive assembly 32 includes: a rotary motor 321 disposed on the cross beam arm 31; and a speed reducer 322 disposed on the cross beam arm 31, the speed reducer 322 being connected to the power output end of the rotary motor 321; wherein, the cross beam arm 31 is rotatably connected to the mounting bracket 22 through the speed reducer 322.

[0043] In the present application, the rotary motor 321 outputs power to the speed reducer 322, and then the speed reducer 322 drives the cross beam arm 31 to rotate, so that the cantilever can rotate reciprocally within a certain angle range, thereby adjusting the angle of the motor rotor a, so that the motor rotor a can be aligned with the motor stator, in order to subsequently push the motor rotor a into the motor stator. The cooperation of the rotary motor 321 and the speed reducer 322 ensures the rotation accuracy of the cross beam arm 31.

[0044] In some embodiments, a slide rail 311 is provided on the cross beam arm 31 along the extending direction, and the feeding mechanism 4 includes: a slider 42 slidably disposed on the slide rail 311; a transmission rod 43 disposed on the cross beam arm 31, the transmission rod 43 being used to drive the slider 42 to slide; and a rotating arm 44 connected to the slider 42, the rotating end of the rotating arm 44 being connected to the flange 41.

[0045] In the present application, the transmission rod 43 drives the slider 42 and the rotating arm 44 to slide along the slide rail 311 to complete the feeding of the motor rotor a. The flange 41 can be rotated by the rotating arm 44 to adjust the angle of the flange 41, ensuring that the bolt holes on the flange 41 can be aligned with the bolt holes on the motor rotor a, so as to perform bolt connection between the flange 41 and the motor rotor a.

[0046] In some embodiments, the slide rails 311 are provided on opposite sides of the cross beam arm 31, and the slider 42 has a U-shaped structure, and both ends of the slider 42 are slidably connected to the two slide rails 311 respectively.

[0047] In this application, since the motor rotor a is very heavy itself, by providing two slide rails 311 and using a slider 42 with a U-shaped structure, the uniformity of the force can be ensured, and the stability of the slider 42 and the motor rotor a during disassembly and assembly can be guaranteed.

[0048] In some embodiments, the feeding mechanism 4 further includes a driving member 45 provided at the end of the transmission rod 43.

[0049] In this application, the driving member 45 drives the transmission rod 43 to rotate, and the rotation of the transmission rod 43 drives the slider 42 to slide. Specifically, a threaded hole is provided on the slider 42, which is in threaded engagement with the external threaded structure of the transmission rod 43, and the slider 42 is driven to slide when the transmission rod 43 rotates.

[0050] In some embodiments, the driving member 45 is a handwheel or a motor.

[0051] In this application, the driving member 45 can be a handwheel. When there is rubbing or interference between the motor rotor a and the motor stator, the position of the slider 42 can be controlled by the handwheel, and the motor rotor a can be adjusted to a suitable position. The transmission rod 43 can be rotated according to the actual situation to conveniently handle different types of situations.

[0052] Optionally, the driving member 45 can also be a motor. By driving the transmission rod 43 to rotate through the motor, there is no need for personnel to work on the cross beam arm 31, which can improve safety.

[0053] In some embodiments, the mounting bracket 22 includes: a lifting connection plate 221 provided at the output end of the lifting machine assembly; an upper mounting bracket 222 connected to the lifting connection plate 221; and an extension plate 223 connected to the upper mounting bracket 222, and the extension plate 223 is used to mount the automatic disassembly and assembly mechanism 5.

[0054] In this application, the lifting connection plate 221 is vertically arranged, the upper mounting bracket 222 is fixedly connected to the lifting connection plate 221, and the extension plate 223 is fixedly connected to the upper mounting bracket 222 by bolts. The upper mounting bracket 222 connects the lifting connection plate 221 and the extension plate 223, and the upper mounting bracket 222 adopts a triangular structure to ensure the stability of the overall structure of the mounting bracket.

[0055] In some embodiments, the automatic disassembly and assembly mechanism 5 includes a manipulator 51 and a pneumatic wrench 52 provided at the movable end of the manipulator 51, and the flange 41 is within the working range of the pneumatic wrench 52.

[0056] In this application, the manipulator 51 adopts a two-axis or three-axis robotic arm, which can drive the pneumatic wrench 52 to move flexibly, move the pneumatic wrench 52 to the required position, and the pneumatic wrench 52 is used for the installation and removal of bolts, so that the flange 41 is connected to or separated from the motor rotor a.

[0057] Specifically, after the motor rotor a is placed in the motor stator, it is inconvenient to disassemble the motor rotor a and the flange 41. Here, with the help of the manipulator 51, the pneumatic wrench 52 can be extended into the motor stator to facilitate the disassembly of the flange 41 and the motor rotor a.

[0058] In some embodiments, it further includes a laser alignment sensor 6, and the laser alignment sensor 6 is arranged on the crossbeam arm 31.

[0059] In this application, the laser alignment sensor 6 can align the motor rotor a and the motor positioning. Under the prompt of the laser alignment sensor 6, the lifting, rotation and feeding of the motor rotor a are carried out to ensure the smooth installation of the motor rotor a and improve the operation efficiency.

[0060] In some embodiments, the chassis truck 1 adopts a self-guided four-wheel chassis truck 1.

[0061] In this application, the self-guided four-wheel chassis truck 1 can move along the set route and automatically move to the required position, ensuring the accuracy of the docking position of the chassis truck 1, and further ensuring the smooth progress of the subsequent disassembly and assembly of the motor rotor a. Only a small range of angle adjustment of the motor rotor a is required to complete the alignment of the motor rotor a and the motor stator.

[0062] The motor rotor disassembly and assembly device of this dump truck fixes the bolts of the flange 41 and the motor rotor a through the automatic disassembly mechanism, moves to the maintenance position through the chassis truck 1, lifts the mounting bracket through the lifting assembly 21 to complete the lifting of the motor rotor a, drives the crossbeam arm 31 to swing through the rotation adjustment mechanism 3 to adjust the angle of the motor rotor a, so that the motor rotor a is aligned with the motor stator, places the motor rotor a into the motor stator through the feeding mechanism 4, and completes the disassembly of the bolts between the flange 41 and the motor rotor a through the automatic disassembly mechanism, thereby completing the installation of the motor rotor a. It can effectively reduce the work intensity of border inspection and maintenance and improve the maintenance operation efficiency.
