DETAILED DESCRIPTION

[0053] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0054] The working platform provided in the embodiments of the present application is described below with reference to FIG. 1 to FIG. 13 .

[0055] Specifically, the working platform includes a main platform, which includes a main base 6, a first main guardrail 8, a mounting seat and a door body 9.

[0056] The main base 6 is used to connect to the driving mechanism of the aerial work equipment to drive the movement of the working platform through the driving mechanism. For example, the driving mechanism can be a scissor-type lifting mechanism, a telescopic arm or a folding arm.

[0057] The first main guardrail 8 is rotatably connected to the main base 6 and can be flipped and folded toward the main base 6, that is, the first main guardrail 8 can be folded toward the inside of the work platform. Optionally, a bending plate is provided on the main base 6, and the first main guardrail 8 is hinged to the bending plate.

[0058] As shown in FIG9 , the mounting base is detachably connected to the first main guardrail 8, is rotatably connected to the main base 6, and can be flipped and folded toward the main base 6. Optionally, the main base 6 is provided with a bending plate, and the mounting base is hingedly connected to the bending plate. The mounting base is detachably connected to the first main guardrail 8 via a pin.

[0059] The door body 9 is rotatably connected to the mounting base. For example, the door body 9 is rotatably connected to the mounting base via a hinge. Optionally, a locking structure is provided between the door body 9 and the mounting base to lock or unlock the door body 9 and the mounting base. Furthermore, when the door body 9 is in the vertical position, the hinge point between the first main guardrail 8 and the main base 6 is located at a height less than the height of the door body 9.

[0060] In the working platform provided in the embodiment of the present application, the mounting base is detachably connected to the first main guardrail 8, and both the mounting base and the first main guardrail 8 are rotatably connected to the main base 6. The door body 9 is disposed on the mounting base. When the guardrails of the working platform need to be folded, the connection between the mounting base and the first main guardrail 8 can be disconnected, and the mounting base can then be folded inward. Since the door body 9 is mounted on the mounting base, the door body 9 can fold inward along with the mounting base.

[0061] With such an arrangement, the door body 9 can be folded inward along with the mounting seat, thereby lowering the height of the working platform, solving or improving the defect in the prior art that the folding height of the working platform is limited by the height of the revolving door and cannot be fully folded, and the door body 9 can also be rotated relative to the mounting seat, thereby opening and closing the passage to the working platform.

[0062] In some embodiments provided herein, the main platform further includes a second main guardrail 1 and a third main guardrail 2. The second main guardrail 1 and the third main guardrail 2 are rotatably disposed on either side of the main base 6, and both the second main guardrail 1 and the third main guardrail 2 can be flipped and folded toward the main base 6.

[0063] The second main guardrail 1 and the third main guardrail 2 are both detachably connected to the side of the first main guardrail 8 close to the main base 6. The side of the first main guardrail 8 close to the main base 6 is the inner side of the first main guardrail 8. The first main guardrail 8, the second main guardrail 1, and the third main guardrail 2 can enclose a main accommodation space.

[0064] During use, the operator can move around within the main accommodation space. When folding the first, second, and third main guardrails 8, 1, and 2, since the second and third main guardrails 1 and 2 are detachably connected to the inner side of the first main guardrail 8, that is, the distance between the second and third main guardrails 1 and 2 is smaller than the width of the first main guardrail 8, the first main guardrail 8 can only be flipped and folded inward after the second and third main guardrails 1 and 2 are flipped and folded inward.

[0065] Referring to FIG7 , further, the hinge point height of one of the second main guardrail 1 and the third main guardrail 2 with the main base 6 is smaller than the hinge point height of the other with the main base 6. For example, taking the example of the hinge point height of the second main guardrail 1 with the main base 6 being smaller than the hinge point height of the third main guardrail 2 with the main base 6, during the folding process, the second main guardrail 1 is first flipped inward and folded, followed by the third main guardrail 2. This arrangement can avoid interference between the third main guardrail 2 and the second main guardrail 1 during the flipping process, and allows the third main guardrail 2 to be placed flat on top of the second main guardrail 1, avoiding a tilted arrangement of the third main guardrail 2, thereby reducing the height dimension of the folded work platform. The same applies in reverse.

[0066] 5 , 6 and 9 , in some embodiments provided in the present application, at least one of the second main guardrail 1 and the third main guardrail 2 includes a main upper guardrail 101 , a main lower guardrail 102 and a main connecting member 103 .

[0067] The main connecting member 103 has two ends pivotally connected to the main upper guardrail 101 and the main lower guardrail 102, respectively. The main upper guardrail 101 can be flipped and folded inward relative to the main lower guardrail 102. For example, the main connecting member 103 can be a bent plate, with its two ends hingedly connected to the main upper guardrail 101 and the main lower guardrail 102. The main lower guardrail 102 is pivotally connected to the main base 6, and the main upper guardrail 101 is detachably connected to the first main guardrail 8.

[0068] The main upper guardrail 101 and the main lower guardrail 102 are connected by the main connecting member 103. When folding the second main guardrail 1 or the third main guardrail 2, the main upper guardrail 101 can be first flipped and folded toward the main lower guardrail 102, that is, the main upper guardrail 101 and the main lower guardrail 102 are folded in half by the main connecting member 103. Then, the main lower guardrail 102 can be folded inward.

[0069] Referring to FIG6 , assuming that the third main guardrail 2 is an integral structure and cannot be folded in half, under the condition that the total height of the third main guardrail 2 remains unchanged when the third main guardrail 2 is in a vertical state, when the third main guardrail 2 is flipped and folded inward, the top of the third main guardrail 2 may exceed the range of the main base 6. Therefore, the position height of the hinge point between the third main guardrail 2 and the main base 6 needs to be raised. At this time, after the third main guardrail 2 is folded inward, the position height of the hinge point of the third main guardrail 2 is higher, resulting in a higher height of the working platform. In this embodiment, the second main guardrail 1 or the third main guardrail 2 can be folded in half, and the height after folding is lower. This can reduce the problem of the second main guardrail 1 or the third main guardrail 2 exceeding the range of the main base 6 after flipping, thereby lowering the position height of the hinge point between the second main guardrail 1 or the third main guardrail 2 and the main base 6, thereby reducing the height of the working platform after folding.

[0070] Referring to FIG. 9 and FIG. 10 , in some embodiments provided in the present application, the main platform further includes a pair of main groove-shaped plates 10 and main limiting pins 11 corresponding to the main groove-shaped plates 10 .

[0071] A pair of main trough plates 10 are each connected to the side of the first primary guardrail 8 near the main base 6, that is, the main trough plates 10 are connected to the inner side of the first primary guardrail 8. For example, the main trough plates 10 can be welded to the posts of the first primary guardrail 8. The notches of the pair of main trough plates 10 are arranged opposite each other, and the pair of main trough plates 10 are respectively used to accommodate the posts of the second primary guardrail 1 and the third primary guardrail 2. Main limit pins 11 are detachably inserted through both sides of the main trough plates 10 and are used to prevent the second primary guardrail 1 or the third primary guardrail 2 from dislodging from the main trough plates 10.

[0072] In this embodiment, when flipping and folding the first, second, and third main guardrails 8, 1, and 2, the primary stop pins 11 of each of the pair of main channel plates 10 are first removed, the second and third main guardrails 1 and 2 are then flipped inward, and finally, the first main guardrail 8 is flipped inward. During use, the first main guardrail 8 is first flipped and opened, followed by the second and third main guardrails 1 and 2. The posts of the second and third main guardrails 1 and 2 are then placed into the pair of main channel plates 10, and finally, the primary stop pins 11 are installed.

[0073] Optionally, the main limiting pin 11 may be a D-shaped pin.

[0074] In some embodiments provided herein, the work platform further includes a secondary platform that is movably connected to the main base 6 and can move toward or away from the first primary guardrail 8. This arrangement can increase the area of ​​the work platform.

[0075] In some embodiments provided in the present application, the secondary platform includes a secondary base 7 , a first secondary guardrail 3 , a second secondary guardrail 4 and a third secondary guardrail 5 .

[0076] The auxiliary base 7 is movably connected to the main base 6 . For example, a guide structure is provided on the main base 6 , and the auxiliary base 7 is movably matched with the guide structure.

[0077] The first, second, and third secondary guardrails 3, 4, and 5 are all rotatably connected to the secondary base 7 and fold inward. The first secondary guardrail 3 is positioned on the side of the secondary base 7 away from the first primary guardrail 8. The first secondary guardrail 3 is positioned between the second and third secondary guardrails 4, 5, and its sides are detachably connected to the inner sides of the second and third secondary guardrails 4, 5, respectively. The first, second, and third secondary guardrails 3, 4, and 5 enclose a secondary storage space.

[0078] As shown in Figure 1, when the secondary platform is retracted, the secondary storage space is located within the primary storage space, and the second secondary guardrail 4 and the third secondary guardrail 5 correspond to the second primary guardrail 1 and the third primary guardrail 2, respectively. When the secondary platform is extended, the secondary storage space and the primary storage space are connected, allowing operators to move between the secondary storage space and the primary storage space.

[0079] Referring to FIG4 , further, the hinge point height of one of the second and third secondary guardrails 4, 5, and the secondary base 7 is smaller than the hinge point height of the other. For example, taking the case where the hinge point height of the second secondary guardrail 4 and the secondary base 7 is smaller than the hinge point height of the third secondary guardrail 5 and the secondary base 7, during the folding process, the second secondary guardrail 4 is first flipped inward and folded, and then the third secondary guardrail 5 is flipped inward and folded. This arrangement can avoid interference between the third secondary guardrail 5 and the second secondary guardrail 4 during the flipping process, and allows the third secondary guardrail 5 to be placed flat on top of the second secondary guardrail 4, preventing the third secondary guardrail 5 from being tilted after folding, thereby reducing the height dimension of the folded work platform. The same applies in reverse.

[0080] 12 , in some embodiments provided herein, at least one of the second secondary guardrail 4 and the third secondary guardrail 5 includes a secondary upper guardrail 401 , a secondary lower guardrail 402 , and a secondary connector 403 .

[0081] The secondary connecting member 403 has two ends that are rotatably connected to the secondary upper guardrail 401 and the secondary lower guardrail 402, respectively. The secondary upper guardrail 401 can be flipped and folded inward relative to the secondary lower guardrail 402. For example, the secondary connecting member 403 can be a bent plate, with its two ends interfacing with the secondary upper guardrail 401 and the secondary lower guardrail 402, respectively. The secondary lower guardrail 402 is rotatably connected to the secondary base 7, and the secondary upper guardrail 401 is detachably connected to the first secondary guardrail 3.

[0082] The secondary upper guardrail 401 and the secondary lower guardrail 402 are connected by the secondary connecting member 403. When folding the second secondary guardrail 4 or the third secondary guardrail 5, the secondary upper guardrail 401 can be first flipped and folded toward the secondary lower guardrail 402, that is, the secondary upper guardrail 401 and the secondary lower guardrail 402 are folded in half by the secondary connecting member 403. Then, the secondary lower guardrail 402 is folded inward.

[0083] In this embodiment, the second or third secondary guardrail 4 or 5 can be folded in half, and the folded height is relatively low. This can reduce the problem of the second or third secondary guardrail 4 or 5 exceeding the range of the secondary base 7 after being flipped, thereby lowering the height of the hinge point between the second or third secondary guardrail 4 or 5 and the secondary base 7, thereby reducing the height of the work platform after folding. For the derivation of the beneficial effect here, reference can be made to the derivation of the beneficial effect of connecting the main upper guardrail 101 and the main lower guardrail 102 via the main connecting member 103 above. The principles of the two are similar and will not be repeated here.

[0084] 12 and 13 , in some embodiments provided in the present application, the auxiliary platform further includes a pair of auxiliary grooved plates 12 and auxiliary positioning pins corresponding to the auxiliary grooved plates 12 .

[0085] A pair of secondary trough plates 12 are rotatably mounted on the columns on either side of the first secondary guardrail 3, and the secondary trough plates 12 are capable of switching between a locked state and an unlocked state. In the locked state, the secondary trough plates 12 rotate and fit over the outer side of the columns of the second secondary guardrail 4 or the outer side of the columns of the third secondary guardrail 5. In the unlocked state, the secondary trough plates 12 rotate and open from the outer side of the columns of the second secondary guardrail 4 or the outer side of the columns of the third secondary guardrail 5. A secondary stop pin 13 detachably passes through both sides of the secondary trough plates 12 and is used to prevent the second secondary guardrail 4 or the third secondary guardrail 5 from dislodging from the secondary trough plates 12.

[0086] In this embodiment, when flipping and folding the first, second, and third secondary guardrails 3, 4, and 5, the secondary limiting pins 13 of each of the pair of secondary trough plates 12 are first removed. The pair of secondary trough plates 12 are then rotated so that the pair of secondary trough plates 12 are opened from the outside of the second and third secondary guardrails 4 and 5, respectively. The first secondary guardrail 3 is then flipped and folded inward, and finally, the second and third secondary guardrails 4 and 5 are flipped and folded inward. When in use, the second and third secondary guardrails 4 and 5 are first flipped and opened in the opposite direction, and then the first secondary guardrail 3 is flipped and opened in the opposite direction. The pair of secondary trough plates 12 are then rotated so that the pair of secondary trough plates 12 are respectively fitted onto the outside of the upright posts of the second and third secondary guardrails 5, and finally, the respective secondary limiting pins 13 are installed.

[0087] As shown in FIG13 , the secondary trough plate 12 is optionally sleeved onto the upright posts of the first secondary guardrail 3, and a notch is provided at the bottom of the trough of the secondary trough plate 12 so that during rotation of the secondary trough plate 12, the notch can clear the upright posts of the first secondary guardrail 3, thereby preventing interference between the bottom of the trough of the secondary trough plate 12 and the upright posts of the first secondary guardrail 3. Furthermore, the secondary trough plate 12 can be rotatably connected to the upright posts of the first secondary guardrail 3 via bolts.

[0088] Optionally, the secondary limiting pin 13 may be a D-shaped pin.

[0089] With reference to Figures 9 and 11 , in some embodiments provided herein, the mounting base includes a pair of mounting posts 14, each detachably connected to the first primary guardrail 8 and spaced apart. Each mounting post 14 is pivotally connected to the main base 6 and can be flipped and folded toward the main base 6. The door body 9 is pivotally connected to one of the mounting posts 14, while the other side of the door body 9 is connected to the other mounting post 14 via a locking mechanism. This arrangement simplifies the mounting base structure.

[0090] As shown in Figures 9 and 11 , the main platform optionally further includes a pair of fixed trough plates 15 and fixed stop pins 16 corresponding to the fixed trough plates 15. The pair of fixed trough plates 15 are both connected to the first primary guardrail 8, with the notches of the pair of fixed trough plates 15 facing inward of the first primary guardrail 8. The pair of fixed trough plates 15 are respectively configured to receive a pair of mounting posts 14. The fixed stop pins 16 detachably pass through both sides of the fixed trough plates 15 and are used to prevent the mounting posts 14 from dislodging from the fixed trough plates 15.

[0091] A guardrail folding method is also provided in an embodiment of the present application. The guardrail folding method can be implemented based on the working platform described above. For example, the specific setting form of the components involved in the guardrail folding method can refer to the description of the same components in the working platform.

[0092] Referring to Figures 1 to 8 , specifically, the guardrail folding method includes:

[0093] The first step is to disassemble the mounting base and the first main guardrail 8 and flip the mounting base inwards as shown in Figure 2. The mounting base is provided with a rotatable door body 9, and the mounting base and the first main guardrail 8 are both rotatably connected to the main base 6.

[0094] Specifically, the mounting base includes a pair of mounting posts 14, each of which is detachably connected to the first main guardrail 8, and a distance is provided between the pair of mounting posts 14, and the door body 9 is mounted between the pair of mounting posts 14. The pair of mounting posts 14 are respectively detached from the first main guardrail 8, and the mounting posts 14 are flipped inward and folded.

[0095] In the second step, as shown in Figure 3, the first secondary guardrail 3 is disassembled from the second secondary guardrail 4 and the third secondary guardrail 5, and the first secondary guardrail 3 is flipped inward and folded. The first secondary guardrail 3 is rotatably mounted on the side of the secondary base 7 away from the first primary guardrail 8 and between the second secondary guardrail 4 and the third secondary guardrail 5. The secondary base 7 is movably connected to the primary base 6.

[0096] Specifically, the second secondary guardrail 4 and the third secondary guardrail 5 are both rotatably connected to the secondary base 7 , and the second secondary guardrail 4 and the third secondary guardrail 5 can be flipped and folded inward.

[0097] In the third step, as shown in FIG4 , the secondary upper guardrail 401 of the second and third secondary guardrails 4 and 5 is flipped and folded toward the secondary lower guardrail 402 , and then the secondary lower guardrail 402 is flipped and folded inwards. The secondary upper guardrail 401 is rotatably connected to the secondary lower guardrail 402 via the secondary connector 403 .

[0098] Specifically, the height of the hinge point between the second and third auxiliary guardrails 4 and 5 and the auxiliary base 7 is smaller than the height of the hinge point between the second and third auxiliary guardrails 5 and the auxiliary base 7 .

[0099] Step 4: Referring to Figures 5-7 , the second and third main guardrails 1 and 2 are removed from the first main guardrail 8 , and the main upper guardrails 101 of the second and third main guardrails 1 and 2 are flipped and folded toward the main lower guardrail 102 , and the main lower guardrail 102 is then flipped and folded inward. The main upper guardrail 101 is pivotally connected to the main lower guardrail 102 via the main connector 103 , and both the second and third main guardrails 1 and 2 are located inboard of the first main guardrail 8 .

[0100] Specifically, the second main guardrail 1 and the third main guardrail 2 are both rotatably connected to the main base 6, and both can be flipped and folded inward. The hinge point of one of the second main guardrail 1 and the third main guardrail 2 with the main base 6 is located at a lower height than the hinge point of the other.

[0101] Step 5: Referring to FIG. 8 , the first main guardrail 8 is turned inward and folded.

[0102] In the guardrail folding method provided in the embodiments of the present application, the door body 9 is folded inward along with the mounting base, thereby reducing the height of the work platform. This solves or improves the existing problem that the folded height of the work platform is limited by the height of the revolving door, resulting in an inability to fully fold. In addition, by folding the second main guardrail 1, the third main guardrail 2, the second secondary guardrail 4, and the third secondary guardrail 5 in half and then flipping them inward, the work platform can be fully folded, effectively reducing the height of the folded work platform.

[0103] Furthermore, based on the above-mentioned folding process, it can be known that the position height of the hinge point between the first secondary guardrail 3 and the secondary base 7 is higher than the position height of the hinge point between the mounting base and the main base 6. The position heights of the hinge points between the second secondary guardrail 4 and the third secondary guardrail 5 and the secondary base 7 are both higher than the position height of the hinge point between the first secondary guardrail 3 and the secondary base 7. The position heights of the hinge points between the second main guardrail 1 and the third main guardrail 2 and the main base 6 are both higher than the position heights of the hinge points between the second secondary guardrail 4 and the third secondary guardrail 5 and the secondary base 7. The position height of the hinge point between the first main guardrail 8 and the main base 6 is higher than the position height of the hinge point between the second main guardrail 1 and the third main guardrail 2 and the main base 6. It should be noted that the position height of the hinge point can be defined as the distance value between the hinge point and the bottom surface of the main base 6.

[0104] An embodiment of the present application also provides an aerial work equipment.

[0105] Specifically, the aerial work equipment includes the work platform as described above, or uses the guardrail folding method as described above.

[0106] Aerial work equipment includes a work platform or uses a guardrail folding method, which also includes corresponding advantages, which will not be repeated here.

[0107] Aerial work equipment includes but is not limited to scissor lift platforms.
