[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] Please refer to Figures 1-8In the embodiment of the present application, a motor dismounting device comprises a telescopic support frame 10, a bracket 30 and a buffer assembly 50. The telescopic support frame 10 comprises a fixed support frame 101 fixedly installed on a support base 17 and a movable support frame 102 slidingly connected to the fixed support frame 101. The fixed support frame 101 is externally provided with a pressure handle connecting rod mechanism 20 for controlling the lifting of the movable support frame 102. The bracket 30 comprises a lifting plate 301 fixedly installed at the top end of the movable support frame 102 and a protective baffle 302 rotatably installed on both sides of the lifting plate 301. The bracket 30 arranged at the top end of the movable support frame 102 is used for placing motor components or maintenance components that need to be lifted.

[0042] When the operation is carried out, the pressure handle connecting rod mechanism 20 controls the movable support frame 102 to slide up and down inside the top end of the fixed support frame 101 under the condition of manual force. After the bracket 30 and the components placed on the top thereof are lifted to the required height, the corresponding construction operation is carried out. When the actual operation changes, the position can be adjusted according to the actual needs. Two people can easily complete the operation without manual force and lifting, thereby ensuring the safety of the workers and the machine.

[0043] The support base 17 can be made of carbon steel plate, cut into a round plate with a size of φ 300-400 mm and a thickness T≥4.0 mm. The center point of the round plate is the force center and also the bearing center point of the device. The size φ 300-400 mm of the round plate support base 17 has three aspects to consider, namely, to ensure that the device can be vertically stored to save floor space, to ensure the effective operation of the device, and to refer to the width distance of the safety passage. In maintenance and repair, the device can reduce the requirements of the environment for the equipment. In actual use, the support base 17 can be fixed to the bottom support frame for positioning and movement, thereby facilitating the convenience of the actual use of the device.

[0044] The fixed support frame 101 can be made of carbon steel Q355B and above high-strength round rods. The fixed support frame 101 is fixedly connected to the center top end of the support base 17. The connection between the fixed support frame 101 and the support base 17 can adopt welding. The size of the fixed support frame 101 can be DN=25. The surface of the round pipe can be made of galvanized carbon steel round pipe or untreated carbon steel round pipe. The length is 800 mm≤L≤1200 mm. The height can be selected according to the actual needs of the site. The minimum height is 800 mm, which is the basic height of human-machine operation. The maximum height is 1200 mm, which is the upper limit value of the stability and safety of the device.

[0045] The movable support frame 102 is made of carbon steel Q355B or higher strength round pipe, is fixedly connected in the round pipe of the fixed support frame 101, is in a sleeving mode, moves linearly and up and down, has a size of DN=20, is connected to the center of the lifting plate 301 of the bracket 30 at the top end in a welding mode, and the surface of the round pipe is made of galvanized carbon steel pipe or untreated carbon steel pipe. The maximum telescopic stroke can be designed as 600 mm. The stability of the device at the maximum extension limit and the safety of human-machine operation are considered.

[0046] The bottom of the lifting plate 301 is provided with an adjusting part 40 for controlling the telescopic movement of both ends, and the adjusting part 40 synchronously controls the horizontal overturning of the protective baffle 302 when the lifting plate 301 is expanded at both ends. The bottom of the lifting plate 301 is connected with a roller holder 60 which is telescopically extended above the lifting plate 301 through a buffer assembly 50, and the bottom of the lifting plate 301 is provided with a boost linkage mechanism 70 which can push the roller holder 60 to move on the outer ring of the movable support frame 102 when the end is extruded.

[0047] In actual application, the bracket 30 can be adjusted to different use states under the control of the adjusting part 40, the protective baffle 302 is rotationally connected to the platform of the lifting plate 301, and when the protective baffles 302 provided on both sides of the bracket 30 are adjusted to have a certain included angle with the lifting plate 301, the included angle between them is within the safety range of 45-75°, the two sides are symmetrically formed, the bending size can be within the range of 70-150 mm, the platform of the lifting plate 301 is used for placing the lifted object, and the corresponding edge protection is used. Its role has two aspects: one is that in addition to the planar stress of the lifted object, the corresponding edge protection effectively avoids the inclination caused by the off-center gravity of the special-shaped part, and the other is that the corresponding edge protection is different from the four-edge protection, which can lift objects of different shapes, while the four-edge protection limits the size range of the lifted object. The corresponding edge protection method has wider applicability to the device, and the operator can also adjust the protective baffles 302 on both sides to be horizontal with the platform of the lifting plate 301 by using the adjusting part 40, and the platform of the lifting plate 301 is expanded at both ends during rotation to the horizontal plane, which can further expand the placement space at the top of the lifting plate 301, facilitating the lifting of large components by the device, thereby further improving the flexibility of the actual use of the device.

[0048] Meanwhile, the bracket 30 is connected with a buffer assembly 50 and a roller holder 60, the top end of the roller holder 60 is movably extended above the lifting plate 301, and can provide a certain buffering effect when the lifted object is placed on the top of the lifting plate 301, so as to avoid a large impact between the heavy object and the bracket 30. When the lifted object is placed on the top of the lifting plate 301, the roller holder 60 is pressed below it, and the component can be stably placed on the platform of the lifting plate 301. When it is necessary to unload the lifted heavy object, the front end of the boost connecting rod mechanism 70 can be slowly abutted to the platform to be transferred in the process of controlling the bracket 30 to slowly move downward by the pressure handle connecting rod mechanism 20. The pressure of the bracket 30 and the component placed on the top thereof can be applied to the pressure handle connecting rod mechanism 2 in cooperation with the corresponding transfer platform. The boost connecting rod mechanism 70 can drive the roller holder 60 to move, and the roller holder 60 can also drive the buffer assembly 50 to extend and retract. When the external force on the pressure handle connecting rod mechanism 20 is removed, the buffer assembly 50 can provide a certain jacking force for the component placed on the bracket 30 in cooperation with the roller holder 60. The staff can easily drag the component on the bracket 30 to transfer and carry.

[0049] The motor dismounting device also comprises an anti-falling assembly 80, wherein the anti-falling assembly 80 comprises a half ratchet wheel 801 fixedly installed outside the fixed support frame 101, and the pressure handle connecting rod mechanism 20 is provided with an elastic positioning piece 802 which can be buckled between the ratchet teeth. The elastic positioning piece 802 is used to limit the automatic falling of the movable support frame 102 controlled by the pressure handle connecting rod mechanism 20. When the staff rotates the pressure handle connecting rod mechanism 20 to control the movable support frame 102 to rise, the pressure handle connecting rod mechanism 20 can drive the elastic positioning piece 802 to slide on the ratchet teeth. The elastic positioning piece 802 can stably hover the movable support frame 102 at different heights, so as to avoid the staff from falling rapidly when lifting the heavy object by the pressure handle connecting rod mechanism 20, and can improve the safety of the actual use of the motor dismounting device.
