[0054] 74 Magnet Specific embodiments

[0055] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present application, and are not used to limit the present application.

[0056] In the prior art, the aerial work platform often has the problem of liquid leakage, 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.

[0057] In view of this, as Figure 2 and Figure 3As shown in the figure, the present application provides a liquid collection device, which includes a steering cylinder liquid receiving tray 31, a liquid receiving tray mounting seat 32, and a limiting structure 34. The liquid receiving tray mounting seat 32 is provided with a connecting portion 321, and the connecting portion 321 is used to connect with the cylinder block of the steering cylinder 2. The steering cylinder liquid receiving tray 31 is provided with a liquid receiving cavity for receiving the leaked liquid of the steering cylinder 2, and the steering cylinder liquid receiving tray 31 is detachably arranged on the liquid receiving tray mounting seat 32. In this way, the liquid collection device can be arranged on the cylinder block of the steering cylinder 2 through the connecting portion of the liquid receiving tray mounting seat 32. When the steering cylinder 2 moves, the liquid collection device can move synchronously with the steering cylinder 2, so as to collect the leaked liquid of the steering cylinder 2 and reduce the risk of liquid leakage during the operation of the aerial work platform. In addition, the steering cylinder liquid receiving tray 31 is detachably arranged on the liquid receiving tray mounting seat 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.

[0058] The limiting structure 34 has a locking state and an unlocking state. In the locking state, the limiting structure 34 can lock the steering cylinder liquid receiving tray 31 in the liquid receiving tray mounting seat 32, and the steering cylinder liquid receiving tray 31 can be taken out from the liquid receiving tray mounting seat 32 in the unlocking state of the limiting structure 34. In this way, the limiting structure 34 can limit the steering cylinder liquid receiving tray 31 to prevent the liquid collection device from disengaging during swinging, making the overall structure more reasonable and reliable.

[0059] 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 buckle 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.

[0060] In some specific embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, the liquid receiving tray mounting seat 32 can be provided with an insertion slot, and the steering cylinder liquid receiving tray 31 is detachably inserted into the insertion slot. In the locking state, the limiting structure 34 can lock the steering cylinder liquid receiving tray 31 in the insertion slot, and the steering cylinder liquid receiving tray 31 can be withdrawn from the insertion slot in the unlocking 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 to prevent the steering cylinder liquid receiving tray 31 from disengaging during operation.

[0061] In some specific embodiments, as Figure 2 、 Figure 3 and Figure 4As 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.

[0062] Furthermore, if Figure 3 and Figure 4 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.

[0063] Furthermore, if Figure 3 and Figure 4 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.

[0064] In some specific embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the liquid collecting device also includes a liquid collecting pan 33 disposed below the cylinder body of the steering oil cylinder 2. The liquid collecting pan 33 is provided with a liquid outlet, and the steering oil cylinder receiving pan 31 is located below the liquid outlet. By providing the liquid collecting pan 33, the liquid collecting pan 33 is arranged close to the steering oil cylinder 2, which can effectively prevent the leaked liquid from splashing when dripping, so that the liquid collecting effect is better.

[0065] In some specific embodiments, the liquid collecting tray 33 extends along the axial direction of the steering cylinder 2, the vertical projection shape of the cylinder body 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 body of the steering cylinder 2 is located within the vertical projection of the liquid collecting tray 33. In this way, the liquid collection effect is better and the structure is more compact.

[0066] 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 oil cylinder 2 and the edge of the vertical projection of the liquid collection tray 33 is less than or equal to 20 mm.

[0067] Furthermore, due to the provision of the liquid collection tray 33, the structure of the liquid receiving tray 31 of the steering oil cylinder can be reduced, thereby making the structure of the liquid collection device more compact. For example, the vertical projection area of the liquid receiving cavity of the liquid receiving tray 31 of the steering oil cylinder is less than or equal to half of the vertical projection area of the liquid collection tray 33. As Figure 2 shown, the liquid receiving tray 31 of the steering oil cylinder can be arranged axially along the steering oil cylinder 2 on one side below the liquid collection tray 33, and the other side below the liquid collection tray 33 can be used to install other structures of the liquid collection device, such as a limiting structure, etc.

[0068] Optionally, as Figure 4 shown, the connecting portion 321 can protrude upward from the edge of the liquid collection tray 33, making the structure of the liquid collection device more compact and reasonable.

[0069] Optionally, as Figure 2 、 Figure 3 and Figure 4 shown, the liquid receiving tray mounting seat 32 can be provided with a connecting portion 321, and the connecting portion 321 is connected to the cylinder block of the steering oil cylinder 2. As Figure 2 and Figure 3 shown, the connecting portion 321 has a mounting hole for connecting to the cylinder block of the steering oil cylinder 2, so that it can be connected to the connecting ear 21 through a fastener.

[0070] Specifically, as Figure 2 shown, the steering oil cylinder 2 is arranged in the left - right direction of the chassis 1 and is located above the traveling wheels and the wheel covers. The liquid collection tray 33 is in the shape of a flat tray. The thickness of the liquid receiving tray 31 of the steering oil cylinder is larger than the thickness of the liquid collection tray 33. In this way, the liquid collection tray 33 can extend axially along the steering oil cylinder 2 and be arranged in the narrow gap between the steering oil cylinder 2 and the wheel cover. The liquid receiving tray 31 of the steering oil cylinder is arranged axially on the inner side below the liquid collection tray 33, so that a space for avoiding components such as the wheel cover can be formed on the outer side below the liquid collection tray 33, and the structure is reasonable and compact.

[0071] In some specific embodiments, the liquid receiving tray 31 of the steering oil cylinder can be a sheet metal part, and a magnetic part 35 for magnetically adsorbing the liquid receiving tray 31 of the steering oil cylinder can be provided on the bottom wall of the insertion slot. The magnetic part 35 can be a circular ring part and can be adjusted to a suitable installation height through fasteners and adjusting gaskets, so as to eliminate the vibration and noise of the liquid receiving tray 31 of the steering oil cylinder during the operation of the aerial work platform.

[0072] Optionally, a liquid absorbing member, such as absorbent cotton, may be provided in the liquid receiving tray 31 of the steering oil cylinder, so as to prevent the leaked liquid in the liquid receiving cavity from overflowing during the operation of the aerial work platform.

[0073] As Figure 1 As shown, in a second aspect of the present application, an aerial work platform is further provided. The aerial work platform includes the above-mentioned liquid collection device and the steering oil cylinder 2, and the connecting portion 321 is connected to the cylinder block of the steering oil cylinder 2. Since the aerial work platform includes the above-mentioned liquid collection device, it also has all the technical effects brought by the liquid collection device, and thus will not be repeated here.

[0074] Wherein, 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 as to swing synchronously with the steering oil cylinder 2.

[0075] 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. Moreover, considering the application requirements 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, a large number of functional modules usually need 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.

[0076] 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. This not only can collect the leaked liquid of the steering oil cylinder 2, reducing the risk of liquid leakage during the operation of the aerial work platform, but also can make the overall structure of the aerial work platform more reasonable and compact, being suitable for being applied to the chassis 1 with a narrow installation space.

[0077] 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 steering oil cylinder 2 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.

[0078] In some specific embodiments, as Figure 3 shown, a connecting ear portion 21 is provided on the cylinder block of the steering oil cylinder 2, and the liquid collection device is installed on the cylinder block through the connecting ear portion 21. The connecting ear portion 21 can be welded to the cylinder block of the steering oil cylinder 2, or the connecting ear portion 21 can be integrally formed with the cylinder block of the steering oil cylinder 2.

[0079] Alternatively, in some other specific embodiments, the liquid collection device can be fixedly connected to the cylinder block of the steering cylinder 2 by a hoop sleeved on the cylinder block of the steering cylinder 2.

[0080] In some specific embodiments, a liquid guiding structure (not shown in the figure) can be provided on the cylinder block of the steering cylinder 2. 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 to 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 guiding plate or a guiding column, etc.

[0081] In some specific embodiments, such as Figure 5 and Figure 6 shown, the aerial work platform further includes a mounting structural member 11, a lifting cylinder 5, and an oil cylinder liquid collection assembly. The mounting structural member 11 is arranged in the chassis 1. A hollowed-out portion is provided at the bottom of the mounting structural member 11. The lifting cylinder 5 is mounted on the mounting structural member 11 and is located above the hollowed-out portion.

[0082] Such as Figure 5 and Figure 6 shown, the oil cylinder liquid collection assembly can include an oil cylinder liquid receiving member 41 and a liquid blocking plate 43. The oil cylinder liquid receiving member 41 is arranged in the hollowed-out portion and is provided with a liquid receiving cavity for receiving the leaked liquid of the oil cylinder. The liquid blocking plate 43 is arranged on the mounting structural member 11 and is used to guide the leaked liquid of the oil cylinder into the liquid receiving cavity. In this way, since the oil cylinder liquid receiving member 41 is provided under 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.

[0083] 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. The oil cylinder liquid receiving member 41 of the aerial work platform of the present application is arranged in the hollowed-out portion at the bottom of the mounting structural member 11, and there is no need to change the thickness of the chassis 1 to install the oil cylinder liquid collection assembly, which can make the overall structure of the aerial work platform more reasonable and compact, suitable for the chassis 1 with a narrow installation space, and is beneficial to reducing the manufacturing cost.

[0084] In addition, since the liquid blocking plate 43 is provided on the mounting structural member 11 of the oil cylinder, the leaked liquid can be gathered and guided into the oil cylinder liquid receiving member 41, which can prevent the leaked liquid from leaking to other parts of the equipment and causing ground pollution.

[0085] Among them, the structural shapes of the oil cylinder liquid receiving member 41 and the liquid blocking plate 43 can be various, and the structures of the oil cylinder liquid receiving member 41 and the liquid blocking plate 43 can be designed according to the installation structure of the oil cylinder. The oil cylinder can be a lifting cylinder or an oil cylinder with other functions, etc. Hereinafter, the oil cylinder liquid collection assembly of the present application will be described by taking the lifting cylinder 5 as an example.

[0086] In some specific embodiments, the oil cylinder liquid collection assembly may include two liquid baffle plates 43 arranged at intervals. The inner plate surfaces of the two liquid baffle plates 43 can define a liquid guiding channel between the outer peripheral wall of the installation structural member 11, and the lifting oil cylinder 5 is located in the liquid guiding channel. Thus, the leaked liquid of the lifting oil cylinder 5 can be introduced into the liquid receiving cavity of the oil cylinder liquid receiving member 41 through the liquid guiding channel.

[0087] 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 5 and Figure 6 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. Thus, the oil cylinder liquid receiving member 41 can be made more miniaturized.

[0088] Optionally, the hollowed-out part can penetrate through the installation structural member 11 along the front-back 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. Thus, no matter whether the aerial work platform is going uphill or downhill, the lower end outlets of the front side liquid guiding channel and the rear side liquid guiding channel can be located above the liquid receiving cavity, so that the leaked liquid can be guided into the liquid receiving cavity through the front side liquid guiding channel and the rear side liquid guiding channel.

[0089] Optionally, as Figure 5 and Figure 6 shown, the installation structural member 11 extends along the left-right direction of the chassis 1, and the plate surfaces of the two liquid baffle plates 43 extend along the front-back direction of the chassis 1. The two liquid baffle plates 43 are arranged at intervals along the left-right direction of the chassis 1 and are provided with lower clamping openings, and the installation structural member 11 is clamped in the lower clamping openings to form a front side liquid guiding channel and a rear side liquid guiding channel with the two liquid baffle plates 43. The lower end outlets of the front side liquid guiding channel and the rear side liquid guiding channel are both located above the liquid receiving cavity.

[0090] Specifically, as Figure 5 and Figure 6 shown, the rear inner plate surfaces of the two liquid baffle plates 43 form a rear side liquid guiding channel with the top surface and the rear side surface of the installation structural member 11, and the front inner plate surfaces of the two liquid baffle plates 43 form a front side liquid guiding channel with the top surface and the front side surface of the installation 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 into 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.

[0091] In some specific embodiments, such as Figure 5 and Figure 6 shown, the oil cylinder liquid collection assembly may further include a chute member 42. The chute member 42 is disposed in the hollowed-out portion and has a liquid receiving tray chute. The oil cylinder liquid receiving member 41 is slidably disposed in the liquid receiving tray chute and can be taken out from the liquid receiving tray chute. Since the oil cylinder liquid receiving member 41 can be taken out from the chute member 42, it is convenient to clean the leaked liquid.

[0092] In some specific embodiments, for the convenience of manufacturing the chute member 42, such as Figure 5 and Figure 6 shown, the liquid receiving tray chute may penetrate along the sliding direction of the oil cylinder liquid receiving member 41. At this time, the oil cylinder liquid collection assembly may further include a liquid receiving member limiting member 46 for limiting the oil cylinder liquid receiving member 41. The liquid receiving member limiting member 46 is disposed inside the liquid receiving tray chute along the sliding direction. In this way, when the oil cylinder liquid receiving member 41 is inserted into the liquid receiving tray chute, the liquid receiving member limiting member 46 can limit the insertion depth of the oil cylinder liquid receiving member 41, thereby realizing the limitation of the oil cylinder liquid receiving member 41.

[0093] Optionally, the chassis 1 may be provided with a strip-shaped hole along the sliding direction of the oil cylinder liquid receiving member 41. The liquid receiving member limiting member 46 is disposed in the strip-shaped hole through a fastener in a position-adjustable manner, so that the position of the liquid receiving member limiting member 46 can be conveniently adjusted, and the structure is more reasonable.

[0094] In some specific embodiments, the oil cylinder liquid collection assembly may further include a locking structure 44. The locking structure 44 has a locked state and an unlocked state. The locking structure 44 can lock the oil cylinder liquid receiving member 41 in the liquid receiving tray chute in the locked state, and the oil cylinder liquid receiving member 41 can be withdrawn from the liquid receiving tray chute in the unlocked 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, and the oil cylinder liquid receiving member 41 can be prevented 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 disposed on the chute member 42 or the cylinder block of the installation structure member 11; the locking structure 44 can be a buckle structure provided 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.

[0095] In some specific embodiments, such as Figure 5 and Figure 6As 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.

[0096] Furthermore, if Figure 5 and Figure 6 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.

[0097] Furthermore, if Figure 5 and Figure 6 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.

[0098] Optionally, in order to facilitate manufacturing and reduce manufacturing costs, the oil cylinder liquid receiving part 41, the slide chute part 42 and the liquid baffle plate 43 can be sheet metal parts. The notch of the slide chute part 42 is provided with an outwardly bent guide flange to facilitate the insertion of the oil cylinder liquid receiving part 41.

[0099] Optionally, the oil cylinder liquid receiving part 41 may be a sheet metal part, and the oil cylinder liquid collecting assembly may further include a plurality of magnets 45, which are disposed on both sides of the liquid receiving tray chute along the sliding direction of the oil cylinder liquid receiving part 41, or the plurality of magnets 45 may be embedded on the bottom wall of the liquid receiving tray chute. In this way, the magnet 45 may absorb the oil cylinder liquid receiving part 41, thereby eliminating the vibration and noise of the oil cylinder liquid receiving part 41 during the operation of the aerial work platform.

[0100] Alternatively, if Figure 7As shown, the aerial work platform may include 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 chute, and the power unit liquid receiving tray 71 is slidably arranged in the liquid receiving tray chute 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.

[0101] 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 dimension of the chassis 1 along 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.

[0102] Moreover, generally, the side of the chassis 1 along 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 in this application is set to be able to lock the power unit liquid receiving tray 71 in the liquid receiving tray chute in the closed state, and the power unit liquid receiving tray 71 can be withdrawn from the liquid receiving tray chute in the open state of the door body 12. In this way, there is no need to additionally set a limiting structure in the chassis 1, making the overall structure of the aerial work platform reasonable and compact, and suitable for the chassis with a small installation space.

[0103] It should be noted that 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 this application, so they will not be elaborated here.

[0104] In some specific embodiments, for the convenience of manufacturing the liquid receiving tray mounting member 72, as Figure 7 shown, the liquid receiving tray chute may 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 chute along the sliding direction. In this way, when the power unit liquid receiving tray 71 is inserted into the liquid receiving tray chute, 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.

[0105] 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.

[0106] 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 bent outward, so as to facilitate the insertion of the liquid receiving tray 71 of the power unit.

[0107] Optionally, the liquid receiving tray 71 of the power unit may be a sheet metal part. The oil 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.

[0108] 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.

[0109] It should be noted that the structural principles of functional components such as the chassis 1, the steering oil cylinder 2, the lifting oil cylinder, and the power unit are well known to those skilled in the art and do not belong to the core improvement part of this application, so they will not be elaborated here.

[0110] In summary, the aerial work platform of the present application is respectively provided with devices for collecting the liquid leakage of the steering oil cylinder, the lifting oil 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 the operation, and at the same time, there are limits on all sides, which can eliminate the risk of the liquid receiving components falling during the operation.
