[0056] 74 Magnet Detailed implementation manners

[0057] The following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present application, and are not used to limit the present application.

[0058] In the prior art, the aerial work platform often has a liquid leakage problem, resulting in the pollution of the ground of the working environment, which not only affects the cleanliness of the ground environment, but also brings safety problems.

[0059] In view of this, as Figure 2 and Figure 3As shown in the figure, the present application provides an oil cylinder liquid collection assembly, which includes an oil cylinder liquid receiving member 41, a chute member 42, and a liquid baffle 43. The oil cylinder liquid receiving member 41 is provided with a liquid receiving cavity for receiving the leaked liquid of the oil cylinder. The chute member 42 is arranged below the oil cylinder and has a liquid receiving tray chute. The oil cylinder liquid receiving member 41 is slidably arranged in the liquid receiving tray chute and can be taken out from the liquid receiving tray chute. In this way, since the oil cylinder liquid receiving member 41 is arranged below the oil cylinder, the leaked liquid of the oil cylinder can be collected, thereby reducing the risk of liquid leakage during the operation of the aerial work platform. Moreover, the oil cylinder liquid receiving member 41 can be taken out from the chute member 42, which is convenient for cleaning the leaked liquid.

[0060] In addition, the liquid baffle 43 is arranged on the installation structure member 11 of the oil cylinder and is used to guide the leaked liquid of the oil cylinder into the liquid receiving cavity, which can aggregate and divert the leaked liquid into the oil cylinder liquid receiving member 41, and can prevent the leaked liquid from leaking to other parts of the equipment and causing ground pollution.

[0061] Among them, the structural shapes of the oil cylinder liquid receiving member 41, the chute member 42, and the liquid baffle 43 can be various, and the structures of the oil cylinder liquid receiving member 41, the chute member 42, and the liquid baffle 43 can be designed according to the installation structure of the oil cylinder. The oil cylinder can be a lifting oil cylinder or an oil cylinder with other functions, etc. Hereinafter, taking the lifting oil cylinder 5 as an example, the oil cylinder liquid collection assembly of the present application will be described.

[0062] In some specific embodiments, the oil cylinder liquid collection assembly may include two spaced liquid baffles 43, and the inner side surfaces of the two liquid baffles 43 can define a liquid guiding flow channel between the outer peripheral wall of the installation structure member 11. In this way, the lifting oil cylinder 5 is arranged on the installation structure member 11 and is located in the liquid guiding flow channel, and the leaked liquid can be guided from the liquid guiding flow channel into the liquid receiving cavity of the oil cylinder liquid receiving member 41.

[0063] Optionally, as Figure 2 and Figure 3 shown, the installation structure member 11 extends along the left - right direction of the chassis 1, and the plate surfaces of the two liquid baffles 43 extend along the front - rear direction of the chassis 1. The two liquid baffles 43 are arranged at intervals along the left - right direction of the chassis 1 and are provided with lower clamping openings. The installation structure member 11 is clamped in the lower clamping openings to form a front - side liquid guiding flow channel and a rear - side liquid guiding flow channel with the two liquid baffles 43. The lower ends of the front - side liquid guiding flow channel and the rear - side liquid guiding flow channel are both located above the liquid receiving cavity.

[0064] Specifically, as Figure 2 and Figure 3As shown, a rear side liquid guiding channel is formed between the inner side surfaces of the rear ends of the two liquid baffle plates 43 and the top surface and the rear side surface of the mounting structural member 11, and a front side liquid guiding channel is formed between the inner side surfaces of the front ends of the two liquid baffle plates 43 and the top surface and the front side surface of the mounting structural member 11. That is, the liquid guiding channel includes a connected front side liquid guiding channel and a rear side liquid guiding channel. The lifting oil cylinder 5 is arranged in the liquid guiding channel, and the leaked liquid can be guided to the liquid receiving cavity of the oil cylinder liquid receiving member 41 through the front side liquid guiding channel or the rear side liquid guiding channel.

[0065] In some specific embodiments, in order to make the structure of the oil cylinder liquid collection assembly more reasonable and compact and suitable for the chassis 1 with a narrow space, the lower plate ends of the two liquid baffle plates 43 are bent towards the direction of approaching each other, so that the lower end outlet of the liquid guiding channel gradually narrows. As Figure 2 and Figure 3 shown, since the lifting oil cylinder 5 is arranged between the upper plate ends of the two liquid baffle plates 43, the distance between the upper plate ends of the two liquid baffle plates 43 is relatively large. By bending the lower plate ends of the two liquid baffle plates 43 towards the direction of approaching each other, the distance between the lower plate ends of the two liquid baffle plates 43 can be made smaller than the distance between the upper plate ends of the two liquid baffle plates 43. In this way, the oil cylinder liquid receiving member 41 can be made more miniaturized.

[0066] In some specific embodiments, the oil cylinder liquid collection assembly may further include a locking structure 44. The locking structure 44 has a locking state and an unlocking state. The locking structure 44 can lock the oil cylinder liquid receiving member 41 in the liquid receiving tray chute in the locking state, and the oil cylinder liquid receiving member 41 can be withdrawn from the liquid receiving tray chute in the unlocking state of the locking structure 44. In this way, the oil cylinder liquid receiving member 41 can be stably limited in the chute member 42 to prevent the oil cylinder liquid receiving member 41 from coming out during operation. Among them, the installation structure and installation position of the locking structure 44 can be various. For example, the locking structure 44 can be arranged on the chute member 42 or the cylinder body of the mounting structural member 11; the locking structure 44 can be a buckle structure arranged between the oil cylinder liquid receiving member 41 and the chute member 42, or the locking structure 44 can also be a structure independent of the oil cylinder liquid receiving member 41, etc.

[0067] In some specific embodiments, such as Figure 2 and Figure 3As shown, the locking structure 44 may include a locking assembly, a locking shaft 441 and an elastic member 442. The locking shaft 441 is movably arranged in the locking assembly and can move axially. An expanded shaft head is provided at one end of the locking shaft 441. One end of the elastic member 442 abuts against the expanded shaft head, and the other end of the elastic member 442 abuts against the locking assembly. In which, when the locking structure 44 is in the locked state, the expanded shaft head extends to the front of the notch of the liquid receiving pan chute and limits the oil cylinder liquid receiving part 41 in the liquid receiving pan chute. In the unlocked state of the locking structure 44, the expanded shaft head compresses the elastic member 442 and avoids the oil cylinder liquid receiving part 41. In this way, the locking and limiting of the oil cylinder liquid receiving part 41 can be achieved.

[0068] Furthermore, if Figure 2 and Figure 3 As shown, in order to facilitate the manufacture and installation of the liquid collection device, the locking assembly includes a fixing member 443 and an axis sleeve 444. The fixing member 443 can be set on the chassis 1 or the mounting structure 11 and is provided with an axis hole. The axis sleeve 444 is set in the axis hole. The end of the locking shaft 441 away from the expanded diameter shaft head is provided with an end limit member 445.

[0069] Furthermore, if Figure 2 and Figure 3 As shown, a retaining ring 446 is respectively provided between the enlarged diameter shaft head and one axial side of the shaft sleeve 444, and between the end stopper 445 and the other axial side of the shaft sleeve 444. The elastic member 442 can be abutted between the retaining ring 446 relatively close to the enlarged diameter shaft head and the enlarged diameter shaft head, so that the structure of the oil cylinder liquid collection assembly can be simpler and more reasonable.

[0070] In some specific embodiments, in order to facilitate the manufacture of the slide member 42, such as Figure 2 and Figure 3 As shown, the liquid receiving tray chute can be through along the sliding direction of the oil cylinder liquid receiving part 41. At this time, the oil cylinder liquid collecting assembly can also include a liquid receiving part stopper 46 for limiting the position of the oil cylinder liquid receiving part 41, and the liquid receiving part stopper 46 is arranged on the inner side of the liquid receiving tray chute along the sliding direction. In this way, when the oil cylinder liquid receiving part 41 is inserted into the liquid receiving tray chute, the liquid receiving part stopper 46 can limit the insertion depth of the oil cylinder liquid receiving part 41, thereby realizing the limiting of the position of the oil cylinder liquid receiving part 41.

[0071] Optionally, the chassis 1 may be provided with strip holes along the sliding direction of the cylinder liquid receiving part 41, and the liquid receiving part limiter 46 may be adjustably arranged in the strip holes through fasteners, so that the position of the liquid receiving part limiter 46 may be conveniently adjusted, and the structure is more reasonable.

[0072] Optionally, for ease of manufacturing and to reduce manufacturing costs, the oil cylinder liquid connection member 41, the chute member 42, and the liquid baffle 43 can be sheet metal parts. The chute opening of the chute member 42 is provided with a guiding flanging that bends outward, thus facilitating the insertion of the oil cylinder liquid connection member 41.

[0073] Optionally, the oil cylinder liquid connection member 41 can be a sheet metal part. The oil cylinder liquid collection assembly can further include a plurality of magnet members 45. The plurality of magnet members 45 are disposed on both sides of the liquid receiving tray chute along the sliding direction of the oil cylinder liquid connection member 41. Alternatively, the plurality of magnet members 45 can also be embedded in the bottom wall of the liquid receiving tray chute. In this way, the magnet members 45 can attract the oil cylinder liquid connection member 41, thereby eliminating the vibration and noise of the oil cylinder liquid connection member 41 during the operation of the aerial work platform.

[0074] As Figure 1 shown, a second aspect of the present application further provides an aerial work platform. The aerial work platform can include the above-mentioned oil cylinder liquid collection assembly, the installation structural member 11, and the oil cylinder. The oil cylinder liquid connection member 41 is located below the oil cylinder, and the oil cylinder is disposed on the installation structural member 11. Since the aerial work platform includes the above-mentioned oil cylinder liquid collection assembly, it also has all the technical effects brought by the oil cylinder liquid collection assembly, so details will not be repeated here.

[0075] Since a relatively large number of functional modules usually need to be arranged in the chassis 1, the structure of the chassis 1 is relatively compact, and the remaining available space in the chassis 1 is often small, making it difficult to install a large-volume liquid collection structure.

[0076] Therefore, in some specific embodiments, as Figure 2 and Figure 3 shown, the bottom of the installation structural member 11 is provided with a hollowed-out portion. The oil cylinder is installed on the installation structural member 11 and is located above the hollowed-out portion. The chute member 42 and the oil cylinder liquid connection member 41 are disposed in the hollowed-out portion, and the liquid baffle 43 is disposed on the installation structural member 11 and can divert the leaked liquid into the oil cylinder liquid connection member 41. In this way, there is no need to change the thickness of the chassis 1 to install the oil cylinder liquid collection assembly, and the structure is more reasonable and compact, which is beneficial to reducing manufacturing costs.

[0077] Optionally, the hollowed-out portion can penetrate the installation structural member 11 along the front-rear direction of the chassis 1, and the front and rear ends of the liquid receiving cavity respectively extend out of the installation structural member 11. In this way, whether the aerial work platform is going uphill or downhill, the lower ends of the front side liquid guiding flow channel and the rear side liquid guiding flow channel can be located above the liquid receiving cavity, so that the leaked liquid can be diverted into the liquid receiving cavity through the front side liquid guiding flow channel and the rear side liquid guiding flow channel.

[0078] In some specific embodiments, as Figure 4 、 Figure 5 and Figure 6As shown in the figure, the aerial work platform may further include a steering oil cylinder 2 and a liquid collection device. The steering oil cylinder 2 is rotatably arranged on the chassis 1. The liquid collection device is arranged on the cylinder block of the steering oil cylinder 2 and swings synchronously with the steering oil cylinder 2. The liquid collection device includes a detachable steering oil cylinder liquid receiving tray 31, and the steering oil cylinder liquid receiving tray 31 is provided with a liquid receiving cavity for receiving the leaked liquid of the steering oil cylinder 2.

[0079] Among them, the steering oil cylinder 2 is rotatably arranged on the chassis 1. The steering oil cylinder 2 drives the link mechanism to move through telescopic movement, so as to realize the steering of the chassis 1. The liquid collection device is arranged on the cylinder block of the steering oil cylinder 2, so that it can swing synchronously with the steering oil cylinder 2.

[0080] Due to the swing of the steering oil cylinder 2, if a fixed liquid collection structure is arranged below the steering oil cylinder 2, the liquid collection layout area of the liquid collection structure needs to cover the movement path area of the steering oil cylinder 2, which will make the volume of the liquid collection structure very large. And, considering the application needs and manufacturing costs, the overall structure and volume of the chassis 1 are often designed to be relatively compact and as small as possible. However, there are usually many functional modules to be arranged in the chassis 1, and the remaining available space in the chassis 1 is often small, making it difficult to install a large-volume liquid collection structure.

[0081] In the aerial work platform of the present application, the liquid collection device is arranged on the cylinder block of the steering oil cylinder 2 and swings synchronously with the steering oil cylinder 2. It can not only collect the leaked liquid of the steering oil cylinder 2, reduce the leakage risk of the aerial work platform during operation, but also make the overall structure of the aerial work platform more reasonable and compact, and is suitable for being applied to the chassis 1 with a narrow installation space.

[0082] In some specific embodiments, as Figure 5 shown, the cylinder block of the steering oil cylinder 2 is provided with a connecting ear 21, and the liquid collection device is installed on the cylinder block through the connecting ear 21. The connecting ear 21 can be welded to the cylinder block of the steering oil cylinder 2, or the connecting ear 21 can be integrally formed with the cylinder block of the steering oil cylinder 2.

[0083] Or, in some other specific embodiments, the liquid collection device can be fixedly connected to the cylinder block of the steering oil cylinder 2 through a hoop sleeved on the cylinder block of the steering oil cylinder 2.

[0084] In some specific embodiments, as Figure 4 、 Figure 5 and Figure 6As shown, the liquid collection device may further include a liquid receiving tray mounting base 32, and the steering cylinder liquid receiving tray 31 is detachably disposed on the liquid receiving tray mounting base 32. When the leaked liquid in the liquid receiving cavity is full, the steering cylinder liquid receiving tray 31 can be directly taken out for cleaning, and the cleaning operation is simple and convenient. The liquid receiving tray mounting base 32 may be provided with a connecting portion 321, and the connecting portion 321 is connected to the cylinder block of the steering cylinder 2. As Figure 3 and Figure 4 shown, the connecting portion 321 has a mounting hole for connecting with the cylinder block of the steering cylinder 2, so that it can be connected to the connecting ear 21 through fasteners.

[0085] In some specific embodiments, a liquid guiding structure (not shown in the figure) may be provided on the cylinder block of the steering cylinder 2, and the liquid guiding structure can guide the leaked liquid on the cylinder block of the steering cylinder 2 to the liquid receiving cavity of the liquid collection device. The liquid guiding structure can be welded on the cylinder block of the steering cylinder 2 or integrally formed on the cylinder block of the steering cylinder 2. The structure of the liquid guiding structure can be various, such as a liquid guiding plate or a liquid guiding column, etc.

[0086] In some specific embodiments, as Figure 4 、 Figure 5 and Figure 6 shown, the liquid collection device further includes a liquid collecting tray 33 disposed below the cylinder block of the steering cylinder 2. The liquid collecting tray 33 is provided with a liquid outlet, and the steering cylinder liquid receiving tray 31 is located below the liquid outlet. By providing the liquid collecting tray 33 and arranging the liquid collecting tray 33 close to the steering cylinder 2, it can effectively prevent the leaked liquid from splashing when dripping, and the liquid collecting effect is better.

[0087] In some specific embodiments, the liquid collecting tray 33 extends along the axial direction of the steering cylinder 2, and the vertical projection shape of the cylinder block of the steering cylinder 2 is matched with the vertical projection shape of the liquid collecting tray 33, and the vertical projection of the cylinder block of the steering cylinder 2 is located within the vertical projection of the liquid collecting tray 33. In this way, the liquid collecting effect is better and the structure is more compact.

[0088] Furthermore, in order to make the structure of the liquid collection device more compact, the minimum distance between the edge of the vertical projection of the cylinder block of the steering cylinder 2 and the edge of the vertical projection of the liquid collecting tray 33 is less than or equal to 20 mm.

[0089] Furthermore, since the liquid collecting tray 33 is provided, the structure of the steering cylinder liquid receiving tray 31 can be reduced, so that the structure of the liquid collection device is more compact. For example, the vertical projection area of the liquid receiving cavity of the steering cylinder liquid receiving tray 31 is less than or equal to half of the vertical projection area of the liquid collecting tray 33. As Figure 3 shown, the steering cylinder liquid receiving tray 31 can be axially disposed below one side of the liquid collecting tray 33, and the other side below the liquid collecting tray 33 can be used to install other structures of the liquid collection device, such as a limiting structure, etc.

[0090] Optionally, as Figure 6 shown, the connecting portion 321 can extend upward from the edge of the liquid collecting tray 33, making the structure of the liquid collecting device more compact and reasonable.

[0091] In some specific embodiments, as Figure 4 、 Figure 5 and Figure 6 shown, the liquid receiving tray mounting seat 32 can be provided with a plug-in groove, and the steering cylinder liquid receiving tray 31 can be detachably plugged into the plug-in groove. The liquid collecting device further includes a limiting structure 34, and the limiting structure 34 has a locked state and an unlocked state. The limiting structure 34 can lock the steering cylinder liquid receiving tray 31 in the plug-in groove in the locked state, and the steering cylinder liquid receiving tray 31 can be withdrawn from the plug-in groove in the unlocked state of the limiting structure 34. In this way, the steering cylinder liquid receiving tray 31 can be stably limited in the liquid receiving tray mounting seat 32, avoiding the steering cylinder liquid receiving tray 31 from coming out during operation. Among them, the installation structure and installation position of the limiting structure 34 can be various. For example, the limiting structure 34 can be arranged on the liquid receiving tray mounting seat 32 or the cylinder block of the steering cylinder 2; the limiting structure 34 can be a snap structure arranged between the steering cylinder liquid receiving tray 31 and the liquid receiving tray mounting seat 32, or the limiting structure 34 can also be a structure independent of the steering cylinder liquid receiving tray 31, etc.

[0092] Specifically, as Figure 4 shown, the steering cylinder 2 is arranged along the left-right direction of the chassis 1 and is located above the traveling wheels and the wheel covers. The liquid collecting tray 33 is in the shape of a flat tray, and the thickness of the steering cylinder liquid receiving tray 31 is larger than the thickness of the liquid collecting tray 33. In this way, the liquid collecting tray 33 can extend along the axial direction of the steering cylinder 2 and be arranged in the narrow gap between the steering cylinder 2 and the wheel cover. The steering cylinder liquid receiving tray 31 is arranged inside and below the liquid collecting tray 33 along the axial direction of the steering cylinder 2, so that a space for avoiding components such as the wheel cover can be formed outside the lower part of the liquid collecting tray 33, and the structure is reasonable and compact.

[0093] In some specific embodiments, as Figure 4 、 Figure 5 and Figure 6As shown, the limiting structure 34 may include a limiting assembly, a limiting shaft 341 and an elastic reset member 342. The limiting assembly may be arranged on the liquid receiving pan mounting seat 32 or the cylinder body of the steering cylinder 2, the limiting shaft 341 is movably arranged in the limiting assembly and can move axially, and one end of the limiting shaft 341 is provided with an expanded diameter shaft head. One end of the elastic reset member 342 abuts on the expanded diameter shaft head, and the other end of the elastic reset member 342 abuts on the limiting assembly. Among them, when the limiting structure 34 is in the locked state, the expanded diameter shaft head extends to the front of the notch of the insertion slot and limits the steering cylinder liquid receiving pan 31 in the insertion slot. When the limiting structure 34 is in the unlocked state, the expanded diameter shaft head compresses the elastic reset member 342 and avoids the steering cylinder liquid receiving pan 31. In this way, the locking and limiting of the steering cylinder liquid receiving pan 31 can be achieved.

[0094] Furthermore, if Figure 5 and Figure 6 As shown, in order to facilitate the manufacture and installation of the liquid collection device, the limiting assembly may include a sleeve fixing 343 and a sleeve 344. The sleeve fixing 343 is arranged on the liquid receiving pan mounting seat 32 and has an axial hole. The sleeve 344 is arranged in the axial hole. The end of the limiting shaft 341 away from the expanded diameter shaft head is provided with a locking member 345.

[0095] Furthermore, if Figure 5 and Figure 6 As shown, a retaining ring 346 passed through the limiting shaft 341 is respectively provided between the expanded diameter shaft head and one axial side surface of the sleeve 344, and between the locking member 345 and the other axial side surface of the sleeve 344. The elastic reset member 342 can abut between the retaining ring 346 relatively close to the expanded diameter shaft head and the expanded diameter shaft head. In this way, the structure of the liquid collecting device can be simpler and more reasonable.

[0096] In some specific embodiments, the steering cylinder fluid collecting pan 31 may be a sheet metal part, and a magnetic part 35 for magnetically adsorbing the steering cylinder fluid collecting pan 31 may be provided on the bottom wall of the insertion slot. The magnetic part 35 may be a circular ring part and may be adjusted to a suitable installation height through fasteners and adjustment gaskets, thereby eliminating vibration and noise of the steering cylinder fluid collecting pan 31 during the operation of the aerial work platform.

[0097] Optionally, a liquid absorbing member, such as oil absorbing cotton, may be provided in the steering cylinder liquid receiving pan 31, so as to prevent the leaked liquid in the liquid receiving cavity from overflowing during the operation of the aerial work platform.

[0098] In some specific embodiments, Figure 7As shown in the figure, the aerial work platform includes a chassis 1, a power unit 6, and a liquid collection assembly. The chassis 1 is provided with a maintenance opening and a door body 12 capable of covering the maintenance opening. The power unit 6 and the liquid collection assembly are respectively arranged inside the chassis 1, and the liquid collection assembly is located below the power unit 6. The liquid collection assembly includes a power unit liquid receiving tray 71 and a liquid receiving tray mounting member 72. The liquid receiving tray mounting member 72 has a liquid receiving tray sliding groove, and the power unit liquid receiving tray 71 is slidably arranged in the liquid receiving tray sliding groove and is provided with a liquid receiving cavity for receiving the leaked liquid of the power unit 6. In this way, the leaked liquid of the power unit can be collected, thereby reducing the risk of liquid leakage during the operation of the aerial work platform.

[0099] Since the power unit 6 is usually arranged at a position relatively close to the middle of the chassis 1, the power unit liquid receiving tray 71 can usually only be taken out along the left-right direction of the chassis 1. Since a relatively large number of functional modules usually need to be arranged in the chassis 1, the structure of the chassis 1 is relatively compact, the size of the chassis 1 in the left-right direction is small, and the remaining available space in the chassis 1 is often small, making it difficult to install a limiting structure for limiting the power unit liquid receiving tray 71.

[0100] Moreover, generally, the side of the chassis 1 in the left-right direction is usually provided with a maintenance opening and a door body 12 capable of covering the maintenance opening. For this reason, the door body 12 of the aerial work platform of the present application is arranged to be able to lock the power unit liquid receiving tray 71 in the liquid receiving tray sliding groove in the closed state, and the power unit liquid receiving tray 71 can be withdrawn from the liquid receiving tray sliding groove in the open state of the door body 12. In this way, there is no need to additionally arrange a limiting structure in the chassis 1, making the overall structure of the aerial work platform reasonable and compact, and suitable for a chassis with a small installation space.

[0101] It should be noted that the aerial work platform can be, for example, a mast-type aerial work platform, a scissor-type work platform, etc. The respective structures of the power unit 6 and the chassis 1 and the rotational connection structure between the two can be various, which are well known to those skilled in the art and do not belong to the core improvement part of the present application, so they will not be elaborated here.

[0102] In some specific embodiments, for the convenience of manufacturing the liquid receiving tray mounting member 72, as Figure 7 shown, the liquid receiving tray sliding groove can penetrate along the sliding direction of the power unit liquid receiving tray 71. At this time, the liquid collection assembly further includes a liquid receiving tray limiting member 73 for limiting the power unit liquid receiving tray 71. The liquid receiving tray limiting member 73 is arranged inside the liquid receiving tray sliding groove along the sliding direction. In this way, when the power unit liquid receiving tray 71 is inserted into the liquid receiving tray sliding groove, the liquid receiving tray limiting member 73 can limit the insertion depth of the power unit liquid receiving tray 71, thereby realizing the limitation of the power unit liquid receiving tray 71.

[0103] Optionally, the chassis 1 may be provided with a strip-shaped hole along the sliding direction of the liquid receiving tray 71 of the power unit. The liquid receiving tray limiting member 73 is disposed in the strip-shaped hole through a fastener with an adjustable position, so that the position of the liquid receiving tray limiting member 73 can be conveniently adjusted, and the structure is more reasonable.

[0104] Optionally, for the convenience of manufacturing and reducing the manufacturing cost, the liquid receiving tray 71 of the power unit and the liquid receiving tray mounting member 72 may be sheet metal parts. The notch of the liquid receiving tray mounting member 72 is provided with a guiding flanging that bends outward, so as to facilitate the insertion of the liquid receiving tray 71 of the power unit.

[0105] Optionally, the liquid receiving tray 71 of the power unit may be a sheet metal part. The liquid cylinder liquid collection assembly may further include a plurality of magnets 74. The plurality of magnets 74 are disposed on both sides of the liquid receiving tray chute along the sliding direction of the liquid receiving tray 71 of the power unit. Alternatively, the plurality of magnets 74 may also be embedded in the bottom wall of the liquid receiving tray chute. In this way, the magnets 74 can attract the liquid receiving tray 71 of the power unit, thereby eliminating the vibration and noise of the liquid receiving tray 71 of the power unit during the operation of the aerial work platform.

[0106] Optionally, for the convenience of opening the door, the door body 12 may be pivotally connected to the chassis 1. Alternatively, in some other specific embodiments, the door body 12 and the chassis 1 may be detachably connected by fasteners.

[0107] In summary, the aerial work platform of the present application is respectively provided with devices for collecting the liquid leakage of the steering cylinder, the lifting cylinder and the power unit, which can greatly improve the liquid leakage collection effect of the entire aerial work platform and has a good application in working occasions with relatively high requirements for the working environment. Moreover, the liquid receiving components of the device are all detachable, which is convenient for cleaning the collected leaked liquid and putting it back, with simple operation and convenient maintenance. The bottom of the device uses magnetic parts to adsorb the liquid receiving components, preventing the vibration and noise of the device during operation, and at the same time, there are limits on all sides, which can eliminate the risk of the liquid receiving components falling during operation.
