[0039] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] like Figure 1 As shown, the maintenance equipment in this embodiment includes a handling device 100 and a placement platform 200.
[0041] The handling device 100 includes a gantry 110, a support arm 120, and a caster wheel 130. The caster wheel 130 is located at the bottom of the gantry 110 and is used to drive the gantry 110 to move. The support arm 120 is installed on the gantry 110 and can reciprocate along the height direction of the gantry 110. The support arm 120 is used to support the module 300 to be repaired.
[0042] For example, such as Figure 2 and Figure 3 As shown, the gantry 110 can be a rectangular frame structure, which can be assembled and welded together from square steel and other materials. In actual use, the gantry 110 can be arranged vertically, that is, the gantry 110 can extend in the vertical direction, and the height direction of the gantry 110 is also the vertical direction, thereby meeting the needs of the support arm 120 to move up and down.
[0043] The support arm 120 can be a U-shaped structure. The support arm 120 can include two arm bodies, both of which can extend in the front-back direction and can be spaced apart in the left-right direction. The support arm 120 can be slidably mounted on the front side of the gantry 110. In use, the support arm 120 can reciprocate in the vertical direction relative to the gantry 110, and the support arm 120 is used to support modules such as power units waiting for maintenance 300, thereby meeting the needs of taking out and putting down the modules 300 waiting for maintenance.
[0044] It should be noted that the corresponding directions in this application can be the various positions of the maintenance equipment in actual use. In actual use, the gantry 110 extends in the vertical direction. In this application, the left side from bottom to top is the left, the right side from bottom to top is the right, the front side from bottom to top is the front, and the rear side from bottom to top is the rear.
[0045] The casters 130 can be omnidirectional casters. There can be two casters 130, which can be installed on the rear side of the bottom of the gantry 110. The two casters 130 can be arranged at intervals in the left and right direction. The casters 130 facilitate the movement of the gantry 110, so that the gantry 110 can be moved to the corresponding position according to the needs of use, thereby improving the convenience of movement.
[0046] Optionally, the movable wheel 130 may have a braking function. For example, the movable wheel 130 may be equipped with a brake. In use, by contacting the brake with the movable wheel 130, the movable wheel 130 can be stopped at the corresponding position, thus meeting the need to fix the maintenance equipment in the corresponding position after it has been moved.
[0047] The top of the placement platform 200 is provided with a tray 210 and a first clearance space 220. The first clearance space 220 is connected to the tray 210 and located on the bottom side of the tray 210. The tray 210 is used to place the module 300 to be repaired, and the first clearance space 220 is used for the support arm 120 to extend into and for the support arm 120 to move up and down.
[0048] For example, such as Figure 4 As shown, the bracket 210 can be located on the top side of the placement platform 200. The bracket 210 can be a rectangular groove. The interior of the placement platform 200 can be a hollow structure. The first clearance space 220 can be a part of the interior space of the placement platform 200. The first clearance space 220 can also be a groove-shaped structure. The top side of the first clearance space 220 is connected to the bracket 210.
[0049] In use, first move the handling device 100 to the cabinet 400 and extend the support arm 120 under the power unit inside the cabinet 400, as follows: Figure 5 As shown in (a) and (b). The support arm 120 can then be driven to rise, lifting the power unit. The transfer wheel 130 can then move the handling device 100, allowing the power unit to be removed from the cabinet 400, as detailed below. Figure 6 As shown in (c) and (d).
[0050] Then, the transport device 100 can be moved to the placement platform 200 by the moving wheels 130. The support arm 120 can first move to the top of the placement platform 200, and then the support arm 120 can be driven to move down. As the support arm 120 moves down, it will pass through the tray 210 and move down into the first clearance space 220. During the downward movement, the power unit will be blocked and placed in the tray 210, specifically as follows: Figure 7 As shown in (e) and (f), the transfer of the power unit box placement platform 200 is completed. After the power unit is transferred to the placement platform 200, the maintenance personnel can carry out maintenance on the power unit on the placement platform 200.
[0051] In some embodiments, the handling device 100 further includes a lifting mechanism 140, which is disposed on the gantry 110 and is connected to the support arm 120 and is used to drive the support arm 120 to reciprocate along the height direction.
[0052] For example, such as Figure 2 As shown, the lifting mechanism 140 can be a self-locking winch. The lifting mechanism 140 can be installed on the rear side of the gantry 110 near the bottom. The lifting mechanism 140 can be connected to the support arm 120 via a chain, which can pass over the top side of the gantry 110. This facilitates the reciprocating drive of the support arm 120 in the vertical direction.
[0053] In some embodiments, the conveying device 100 further includes a counterweight 150, both the counterweight 150 and the lifting mechanism 140 are located on one side of the gantry 110, and the support arm 120 is located on the other side of the gantry 110. For example, as Figure 2 and Figure 3 As shown, the counterweight 150 can be a lead block or the like. Both the counterweight 150 and the lifting mechanism 140 can be arranged on the rear side of the gantry 110, where the counterweight 150 can be located below the lifting mechanism 140, and the support arm 120 can be located on the front side of the gantry 110.
[0054] Since the support arm 120 needs to support loads such as power units during use, the counterweight 150 can balance and lower the center of gravity, thereby preventing the handling device 100 from tilting easily during use and ensuring the structural stability of the operation.
[0055] In some embodiments, the bottom of the gantry 110 is provided with a placement groove 160, the groove opening of the placement groove 160 is arranged facing upward, the counterweight 150 is placed in the placement groove 160, and the moving wheel 130 is provided on the bottom side of the placement groove 160.
[0056] For example, such as Figure 2 and Figure 3As shown, the placement slot 160 can be a box-shaped structure. The placement slot 160 can be fixed to the bottom of the rear side of the gantry 110. The fixing method can be welding, fastener fixing, etc. In use, the counterweight 150 can be placed in the placement slot 160. This realizes the movable assembly of the counterweight 150, so that the number of counterweights 150 and the overall weight can be flexibly adjusted as needed.
[0057] In some embodiments, the gantry 110 is provided with a handrail 170, which is located on the same side of the gantry 110 as the counterweight 150, and extends along the height direction of the gantry 110. For example, as Figure 2 and Figure 3 As shown, the handrail 170 can be installed on the rear side of the gantry 110. The handrail 170 can be a tubular structure and can extend in the vertical direction. Both the top and bottom ends of the handrail 170 can be connected and fixed to the gantry 110. In use, a person can hold the handrail 170, which facilitates the movement of the handling device 100 by human intervention.
[0058] Optionally, two handrails 170 can be provided. Both handrails 170 can be located on the rear side of the gantry 110, and the two handrails 170 can be arranged alternately in the left and right directions, so that the operator's two hands can hold different handrails 170 respectively, further improving the convenience of operation.
[0059] In some embodiments, the gantry 110 includes a frame 1101 and a front leg 1102. A support arm 120 is mounted on the frame 1101, and the front leg 1102 is disposed on the frame 1101. The front leg 1102 and the support arm 120 are located on the same side of the frame 1101, and the free end of the front leg 1102 is provided with a roller 11021. The placement platform 200 is provided with a second clearance space 230, which is located on the bottom side of the first clearance space 220. The second clearance space 230 is used for the front leg 1102 to extend into.
[0060] For example, such as Figure 3 As shown, the frame 1101 can be a rectangular structure, and the frame 1101 can be arranged vertically. The front legs 1102 can be rod-shaped structures, and there can be two front legs 1102. Both front legs 1102 can be integrally formed on the bottom of the front side of the frame 1101, and the two front legs 1102 can be arranged at intervals in the left and right directions.
[0061] like Figure 4As shown, the second clearance space 230 can be a portion of the internal space of the placement platform 200, and the second clearance space 230 can be connected to the first clearance space 220. In use, when the support arm 120 moves above the tray 210, the front foot 1102 can simultaneously extend into the second clearance space 230, thereby achieving the function of avoiding the front foot 1102.
[0062] like Figure 3 As shown, each front foot 1102 can be equipped with a roller 11021 at its front end, and the rotation axis of the roller 11021 can be arranged to extend in the left and right direction. The two rollers 11021 and the two movable wheels 130 mentioned above can form a four-corner support, thereby improving the stability of the bottom support and facilitating the overall movement and adjustment of the handling device 100.
[0063] In some embodiments, the placement platform 200 includes two slides arranged opposite each other in the width direction of the placement platform 200, and a slot 210 is formed between the two slides.
[0064] For example, such as Figure 4 As shown, both slides can be corner plate-shaped structures, the width direction of the placement platform 200 can be left and right, both slides can extend along the front and back direction, and the two slides can be arranged in a mirror-symmetrical manner in the left and right direction. The aforementioned bracket 210 can be formed between the two slides, thereby facilitating the arrangement of the bracket 210.
[0065] In some embodiments, such as Figure 4 As shown, the placement platform 200 also includes two bases 240, two top supports 250, and multiple first columns 260. The two bases 240 are arranged opposite each other in the width direction. For example, both bases 240 can be channel steel structures, both bases 240 can extend in the front-back direction, and the two bases 240 can be spaced apart in the left-right direction.
[0066] The two top supports 250 are arranged opposite each other in the width direction. For example, both top supports 250 can be plate-like structures, both top supports 250 can extend in the front-back direction, and the two top supports 250 can be arranged at intervals in the left-right direction.
[0067] Two slides are respectively located inside the two top supports 250, for example, as Figure 4 As shown, the left slide can be fixed to the right side of the left top support 250, and the right slide can be fixed to the left side of the right top support 250.
[0068] Both bases 240 are connected to two top supports 250 respectively via at least one first post 260, and the top of each first post 260 is connected to the outer side of the corresponding top support 250. For example, as Figure 4 As shown, four first columns 260 can be provided. Each of the four first columns 260 can be a round rod and can extend in the vertical direction. Two of the first columns 260 can be fixed between the left base 240 and the left top support 250, and these two first columns 260 can be arranged at intervals in the front-back direction. The other two first columns 260 can be fixed between the right base 240 and the right top support 250, and these two first columns 260 can also be arranged at intervals in the front-back direction.
[0069] This allows for the hollowing out of the placement platform 200, which not only supports the power unit but also allows the front legs 1102, support arms 120, etc., to extend into the placement platform 200, thus achieving a clearance effect. Secondly, it can also reduce material consumption and lower costs.
[0070] In some embodiments, such as Figure 4 As shown, the placement platform 200 also includes a first crossbeam 270, two second columns 280, and multiple second crossbeams 290. The first crossbeam 270 is located on one side of the extension direction of the base 240, and the first crossbeam 270 is connected between the two first columns 260. For example, the extension direction of the base 240 can be front-to-back, the first crossbeam 270 can be located on the rear side of the placement platform 200, the first crossbeam 270 is horizontally arranged and can extend along the left-to-right direction, and the two ends of the first crossbeam 270 can be respectively connected between the two first columns 260 on the front side.
[0071] Two second columns 280 are arranged opposite each other in the width direction. The bottom ends of the two second columns 280 are connected to the first crossbeam 270, and the top ends of the two second columns 280 are connected to the two slides respectively.
[0072] For example, such as Figure 4 As shown, both second columns 280 can be round rods. The two second columns 280 can be arranged in parallel and spaced apart in the left and right directions. Both second columns 280 can be located in front of the placement platform 200. The bottom end of each second column 280 can be connected and fixed to the first crossbeam 270, and the top end of each second column 280 can be fixedly connected to the rear end of the corresponding slide.
[0073] The first clearance space 220 can be located above the first crossbeam 270, while the second clearance space 230 can be located below the first crossbeam 270. Thus, the first crossbeam 270 can serve to separate the first clearance space 220 and the second clearance space 230.
[0074] Multiple second crossbeams 290 are located on the opposite side of the extending direction of the base 240, and each second crossbeam 290 connects between two first columns 260 or between two bases 240. For example, as Figure 4 As shown, two second crossbeams 290 can be provided, both of which can be located on the front side of the placement platform 200, and the two second crossbeams 290 can be arranged at intervals in the vertical direction, and each second crossbeam 290 can extend in the horizontal direction. The two ends of the second crossbeam 290 located at the bottom can be connected and fixed to the front ends of the two bases 240 respectively, and the two ends of the second crossbeam 290 located at the top can be connected and fixed to the two first columns 260 on the front side respectively.
[0075] In some embodiments, the placement platform 200 further includes at least one storage box 2100, which is disposed on the top side of the placement platform 200. For example, as Figure 4 As shown, the storage box 2100 can be square-shaped, and two storage boxes 2100 can be provided. The two storage boxes 2100 can be fixed to the top side of the front end of the two top supports 250 respectively. In use, the storage box 2100 can be used to store unused parts such as screws and bolts.
