[0026] The following is combined with Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0027] Example 1

[0028] Reference Figure 1 A power assist device for installing a bus air-conditioning compressor includes a support frame 1, a base 2, a connecting rod 3, a linear motor 4, a mechanical arm 5 and a hook 6.

[0029] Reference Figure 1-2 The support frame 1 includes a column 101 and a guide rail 102.

[0030] In this embodiment, the number of columns 101 is 4, and they are vertically arranged at the position where the air-conditioning compressor needs to be installed, and the four columns 101 form a rectangular area, providing a corresponding position area for the guide rail 102 in the power assist device. The guide rail 102 is arranged at the upper end of the column 101; refer to Figure 2 A guide rail 102 is connected to the same position on the upper ends of every two columns 101, so that the guide rails 102 are in a horizontal state. At the same time, a guide rail 102 is also installed between the two parallel guide rails 102, forming the final motion track. The number of columns 101 and the shape of the motion track formed by the guide rails 102 are not required here and can be adaptively adjusted according to needs.

[0031] Reference Figure 3 A support rod 103 is provided between the columns 101 in the support frame 1; and both ends of the support rod 103 are fixedly connected to the top ends of the two columns 101, respectively, in order to improve the stability of the columns 101 through the support rod 103. At the same time, the height of the support rod 103 on the columns 101 is higher than the height of the guide rail 102 on the columns 101. This is because a diagonal brace 104 is provided between the connected columns 101 and the support rod 103. The height difference between the support rod 103 and the guide rail 102 facilitates the installation of the diagonal brace 104; and the provision of the diagonal brace 104 also improves the overall stability of the support frame 1.

[0032] Reference Figure 1-2 , the base 2 is nested on the guide rail 102 and is located at the lower end of the guide rail 102 in a suspended manner. Specifically, the upper bottom surface of the base 2 is fixedly connected to a pulley through a connector, and the pulley just matches the guide rail 102, and the pulley is set on the upper part of the guide rail 102, and then the pulley is fixed to the guide rail 102 through the connectors on both sides of the pulley, and finally the base 2 can be nested on the guide rail 102 and moved. Among them, the connector can be a small steel plate to fix the central axis of the pulley to the base 2 without affecting the operation of the pulley. When in use, a drive motor can be installed on the base 2 to realize the operation of the base 2; at the same time, the guide rail 102 can also be set as a screw guide rail, so as to cooperate with the motor to drive the operation of the base 2; and the operation of the base 2 can select different drive modes, which will not be repeated here.

[0033] Reference Figure 1 A vertical connecting rod 3 is provided on the lower surface of the base 2, that is, the upper end of the connecting rod 3 is fixedly connected to the lower surface of the base 2 by welding; the purpose is to provide an installation space for the linear motor 4 and provide a vertical track for the linear motor 4, and the linear motor 4 is nested on the connecting rod 3, and the linear motor 4 can rotate around the connecting rod 3.

[0034] Reference Figure 5 The robotic arm 5 includes a first mechanical rod 501, a swivel joint 502, and a second mechanical rod 503. Specifically, the first mechanical rod 501, the swivel joint 502, and the second mechanical rod 503 are sequentially connected. Specifically, the swivel joint 502 is disposed between the first mechanical rod 501 and the second mechanical rod 503, and the swivel joint 502 is connected to one end of each of the first mechanical rod 501 and the second mechanical rod 503. Simultaneously, the other end of the first mechanical rod 501 is connected to the hook 6, and the other end of the second mechanical rod 503 is fixedly connected to the linear motor 4.

[0035] In this embodiment, the first mechanical rod 501 is an L-shaped mechanical rod, one end of which is nested and fixed on the rotary joint 502, while the other end of the L-shaped mechanical rod is connected to the movable hook 6. The robotic arm 5 also includes a counterweight 504, which is arranged at the top of the end of the second mechanical rod 503 connected to the linear motor 4. The second mechanical rod 503 is a telescopic mechanical rod. Through the telescopic properties of the second mechanical rod 503 and the counterweight 504, it can drive the rotary joint 502 to swing up and down within a certain range. The movable hook 6 connected to the L-shaped first mechanical rod 501 and the ability of the linear motor 4 to rotate on the connecting rod 3 can thus be moved to any position.

[0036] The movable hook provided on the first mechanical rod 501 is used to hook the air-conditioning compressor. According to the mutual cooperation of the base 2, the connecting rod 3, the linear motor 4 and the mechanical arm 5, the air-conditioning compressor can be rotated to any position, thereby assisting the process of installing the air-conditioning compressor on the bus.

[0037] In this embodiment, the second mechanical rod 503 is fixedly connected to the moving element of the linear motor 4, so that when the linear motor 4 moves, it can drive the second mechanical rod 503 to move, thereby driving the entire robotic arm 5 to move vertically. Limit blocks are also provided on the linear motor 4 to limit the range of vertical motion of the robotic arm 5 and prevent drift of the power assist device when in a restricted state.

[0038] During the use of the power assist device, the horizontal movement of the power assist device is achieved by moving the base 2 on the guide rail 102, and the vertical operation range of the robot arm 5 is expanded according to the provided support rod 103, linear motor 4 and robot arm 5, thereby ensuring that the robot arm 5 can reach any position, and then the hook 6 fixedly connected to the robot arm 5 is used to hang the air-conditioning compressor, thereby assisting the installation process of the air-conditioning compressor.

[0039] In order to control costs and ensure that the device has sufficient supporting capacity, the columns, connecting rods and diagonal braces are made of 45 steel, while the guide rails are made of A18 aluminum alloy.

[0040] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
