Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0019] The embodiment of the present application provides a water pump backrest wheel 700 disassembly device, such as Figure 1 and Figure 2 As shown, the water pump backrest wheel 700 disassembly device includes a walking chassis 100, a disassembly component 200, a telescopic component 300, a pushing component 400 and a controller 600.

[0020] The disassembly member 200 includes a baffle 210 and a fixed frame 220 ; wherein the baffle 210 is provided with a groove 211 for accommodating the water pump shaft 800 ; the front end of the fixed frame 220 is connected to the disassembly member 200 , and the rear end of the fixed frame 220 is rotatably connected to the walking chassis 100 .

[0021] The two ends of the telescopic member 300 are respectively hinged to the walking chassis 100 and the fixed frame 220, and are configured to drive the fixed frame 220 to rotate so that the groove 211 approaches and moves away from the water pump shaft 800; specifically, during the process of the telescopic member 300 extending and shortening, one end of the telescopic member 300 drives the fixed frame 220 to rotate. Figure 1 and Figure 2 Taking the installation position shown as an example, when the telescopic member 300 is extended, the upper end of the telescopic member 300 drives the fixed frame 220 to rotate, and the disassembly member 200 is lifted upward as a whole; when the telescopic member 300 is shortened, the upper end of the telescopic member 300 drives the fixed frame 220 to rotate, and the disassembly member 200 falls downward as a whole. For example, the telescopic member 300 can be an electric push rod that can be extended and shortened.

[0022] The rear end of the push member 400 is connected to the fixing frame 220, and the front end of the push member 400 is used to push after aligning with the end surface of the water pump shaft 800. Specifically, the push member 400 can be extended and shortened. After the front end of the push member 400 is aligned with the end surface of the water pump shaft 800, the push member 400 is extended, and then the front end of the push member 400 pushes the water pump shaft 800. Figure 3 FIG. 4 is a schematic diagram showing that the front end of the push member 400 is aligned with the end face of the water pump shaft 800. Then, after the maintenance personnel operates the controller 600, the controller 600 controls the push member 400 to extend the push member 400, and the front end of the push member 400 pushes the water pump shaft 800. Figure 4 As shown, while the push member 400 pushes the water pump shaft 800, the baffle 210 blocks the water pump back wheel 700 from moving, thereby enabling the water pump back wheel 700 to move on the water pump shaft 800 until the water pump back wheel 700 is separated from the water pump shaft 800. For example, the push member 400 may be an electric push rod.

[0023] The controller 600 is electrically connected to the traveling chassis 100, the telescopic member 300 and the pushing member 400, and is configured to control the movement of the traveling chassis 100, the telescopic member 300 and the pushing member 400 under the operation of the maintenance personnel. When the water pump backrest wheel 700 disassembly device is in use, the maintenance personnel operate the controller 600 to move the traveling chassis 100 to face the water pump shaft 800, and then control the movement of the telescopic member 300 to rotate the disassembly member 200 until the groove 211 on the baffle plate 210 surrounds the water pump shaft 800, and the water pump backrest wheel 700 is located on the side of the baffle plate 210 facing the pushing member 400, as shown in FIG. Figure 3 As shown; finally, the push member 400 is controlled so that the front end of the push member 400 pushes the water pump shaft 800, thereby making the baffle 210 block the movement of the water pump back wheel 700, so that the water pump back wheel 700 moves on the water pump shaft 800 until the water pump back wheel 700 is detached from the water pump shaft 800, as shown Figure 4 shown.

[0024] Therefore, the water pump back wheel 700 disassembly device in the embodiment of the present application can disassemble the water pump back wheel 700 under the control of maintenance personnel, saving manpower, and the disassembly process of the water pump back wheel 700 is continuous, so that the disassembly can be completed in a shorter time.

[0025] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the walking chassis 100 includes a walking vehicle 110, a linear motion mechanism 120 and a mounting bracket 130. The linear motion mechanism 120 is connected to the top of the walking vehicle 110, and the walking vehicle 110 and the linear motion mechanism 120 are electrically connected to the controller 600. The mounting bracket 130 is connected to the power output part of the linear motion mechanism 120, and the rear end of the fixed frame 220 is rotatably connected to the top of the mounting bracket 130, and the lower end of the telescopic member 300 is hinged to the mounting bracket 130.

[0026] Under the control of the controller 600, the walking vehicle 110 can move forward, backward and turn on the ground; under the control of the controller 600, the linear motion mechanism 120 can drive the mounting bracket 130 to move linearly on the walking vehicle 110, and then drive the disassembly part 200 connected to the mounting bracket 130 to move linearly.

[0027] When the disassembly member 200 is driven by the telescopic member 300 to rotate until the groove 211 surrounds the water pump shaft 800, and the water pump back wheel 700 is located on the side of the baffle 210 facing the push member 400, there may be a gap between the baffle 210 and the water pump back wheel 700, and the disassembly member 200 connected to the mounting bracket 130 can be driven to move away from the water pump back wheel 700 by controlling the linear motion mechanism until the baffle 210 is close to the water pump back wheel 700. In addition, when the push member 400 pushes the water pump to rotate, the disassembly member 200 can be driven to move away from the water pump back wheel 700 by the linear motion mechanism of the controller 600, so that the water pump back wheel 700 can be quickly separated from the water pump shaft 800.

[0028] Specifically, continue to refer to Figure 1 and Figure 2 The linear motion mechanism includes a screw module 121 and a slide rail 122. The screw module 121 and the slide rail 122 are arranged in parallel and are both connected to the top of the walking chassis 100. The screw module 121 is electrically connected to the controller 600. The mounting bracket 130 is fixedly connected to the power output part of the screw module 121 and is slidably connected to the slide rail 122.

[0029] When the disassembly part 200 needs to be moved, the controller 600 controls the screw module 121 to work, and the moving part of the screw module 121 moves linearly, thereby driving the mounting bracket 130 to slide along the slide rail 122, and the disassembly part 200 connected to the mounting bracket 130 moves accordingly.

[0030] Of course, the linear motion mechanism is not limited to the above structure. In other embodiments of the present application, the linear motion mechanism can also be other specific structures; for example, the linear motion mechanism includes an electric push rod and a slide rail 122 and the slide rail 122 is arranged in parallel and are both connected to the top of the walking chassis 100, the electric push rod is electrically connected to the controller 600, the mounting bracket 130 is fixedly connected to the front end of the electric push rod, and is slidably connected to the slide rail 122.

[0031] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the traveling chassis 100 further includes a lifting mechanism 140. The lifting mechanism 140 is installed on the traveling vehicle 110 and is electrically connected to the controller 600. The linear motion mechanism 120 is connected to the top of the lifting mechanism 140.

[0032] The lifting mechanism 140 can drive the linear motion mechanism 120 to rise and fall under the control of the controller 600, and then when the walking vehicle 110 moves to face the water pump shaft 800, the maintenance personnel can operate the controller 600 to control the lifting mechanism 140 to drive the linear motion mechanism 120 to rise or fall to a suitable position, so that the groove 211 on the baffle 210 can surround the water pump shaft 800. After the water pump backrest wheel 700 disassembly device completes the disassembly of the water pump backrest wheel 700, the maintenance personnel can operate the controller 600 to control the lifting mechanism 140 to drive the linear motion mechanism 120 to fall, thereby lowering the overall center of gravity of the water pump backrest wheel 700 disassembly device, so that the water pump backrest wheel 700 disassembly device is more stable during the movement.

[0033] Specifically, the lifting mechanism 140 includes a bearing platform 141, a screw lift 142 and a drive motor 143. The drive motor 143 and the screw lift 142 are installed on the top of the walking vehicle 110, and the drive motor 143 is connected to the screw lift 142 and electrically connected to the controller 600. The bearing platform 141 is arranged on the top of the screw lift 142, and the linear motion mechanism 120 is installed on the top surface of the bearing platform 141.

[0034] When the height of the disassembly part 200 needs to be adjusted, the controller 600 controls the drive motor 143 to rotate, and the drive motor 143 drives the screw lift 142 to extend or shorten in the height direction. The top of the screw lift 142 drives the supporting platform 141 to rise and fall, thereby realizing the height adjustment of the disassembly part 200.

[0035] Furthermore, a plurality of guide holes 111 are provided on the top of the traveling vehicle 110, and the lifting mechanism 140 further includes a plurality of guide rods 144. The top ends of the plurality of guide rods 144 are connected to the top surface of the carrying platform 141, and the bottom ends of the plurality of guide rods 144 are slidably disposed in the plurality of guide holes 111, respectively.

[0036] When the screw lift 142 drives the carrying platform 141 to move in the height direction, the multiple guide rods 144 move with the carrying platform 141, and the multiple guide holes 111 on the walking vehicle 110 are used to guide the moving direction of the carrying platform 141 to prevent the carrying platform 141 from shifting in the horizontal direction.

[0037] Of course, the lifting mechanism 140 is not limited to the above structure. In other embodiments of the present application, the lifting mechanism 140 can also be other specific structures; for example, the lifting mechanism 140 includes a double-scissors electric lifting platform, which is arranged on the top of the walking vehicle 110, and the linear moving mechanism is installed on the top of the double-scissors electric lifting platform, and the motor of the double-scissors electric lifting platform is electrically connected to the controller 600.

[0038] Continue to refer to Figure 1 and Figure 2 In the embodiment of the present application, the water pump backrest wheel 700 disassembly device further includes a counterweight 500, which is connected to the end of the chassis away from the baffle 210. The counterweight 500 can prevent the water pump backrest wheel 700 disassembly device from tipping over during operation.

[0039] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0040] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
