DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Combine the following Figures 1 to 13 The working platform provided in the embodiments of the present invention is described.

[0053] 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.

[0054] The main base 6 is used to be connected to a 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.

[0055] The first main guardrail 8 is rotatably connected to the main base 6, and the first main guardrail 8 can be turned and folded toward the main base 6, that is, the first main guardrail 8 can be folded toward the inside of the working platform. Optionally, a bending plate is provided on the main base 6, and the first main guardrail 8 is hinged to the bending plate.

[0056] refer to Fig. 9 As shown, the mounting seat is detachably connected to the first main guardrail 8, the mounting seat is rotatably connected to the main base 6, and the mounting seat can be flipped and folded toward the main base 6. Optionally, the main base 6 is provided with a bending plate, and the mounting seat is hingedly connected to the bending plate. The mounting seat is detachably connected to the first main guardrail 8 through a pin shaft.

[0057] The door body 9 is rotatably connected to the mounting seat. For example, the door body 9 is rotatably connected to the mounting seat via a hinge. Optionally, a locking structure is provided between the door body 9 and the mounting seat, and the locking structure is used to lock or unlock the door body 9 and the mounting seat. Further, when the door body 9 is in a vertical state, the position height of the hinge point between the first main guardrail 8 and the main base 6 is less than the height of the door body 9.

[0058] In the working platform provided in the embodiment of the present invention, the mounting seat is detachably connected to the first main guardrail 8, and both the mounting seat and the first main guardrail 8 are rotatably connected to the main base 6, and the door body 9 is arranged on the mounting seat. When the guardrail of the working platform needs to be folded, the connection between the mounting seat and the first main guardrail 8 can be disassembled, and then the mounting seat can be folded inwardly. Since the door body 9 is installed on the mounting seat, the door body 9 can be folded inwardly with the mounting seat.

[0059] With such 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; the door body 9 can also be rotated relative to the mounting seat, thereby opening and closing the passage to the working platform.

[0060] In some embodiments provided by the present invention, 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 arranged on both sides of the main base 6, and the second main guardrail 1 and the third main guardrail 2 can be turned and folded toward the main base 6.

[0061] 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, and the side of the first main guardrail 8 close to the main base 6 is the inner side of the first main guardrail 8. And the first main guardrail 8, the second main guardrail 1 and the third main guardrail 2 can enclose a main accommodation space.

[0062] During use, the operator can move around in the main accommodation space. When folding the first main guardrail 8, the second main guardrail 1 and the third main guardrail 2, since the second main guardrail 1 and the third main guardrail 2 are both detachably connected to the inner side of the first main guardrail 8, that is, the distance between the second main guardrail 1 and the third main guardrail 2 is smaller than the width of the first main guardrail 8, the first main guardrail 8 can only be turned inwards and folded after the second main guardrail 1 and the third main guardrail 2 are turned inwards and folded.

[0063] refer to Figure 7 As shown, further, the position height of the hinge point between the second main guardrail 1 and the third main guardrail 2 and the main base 6 is smaller than the position height of the hinge point between the other and the main base 6. For example, taking the case where the position height of the hinge point between the second main guardrail 1 and the main base 6 is smaller than the position height of the hinge point between the third main guardrail 2 and the main base 6, during the folding process, the second main guardrail 1 is first flipped inwards and folded, and then the third main guardrail 2 is flipped inwards and folded. Such a setting can avoid the problem of interference between the third main guardrail 2 and the second main guardrail 1 during the flipping process, and enable the third main guardrail 2 to be placed flat on top of the second main guardrail 1, avoiding the third main guardrail 2 from being tilted, thereby reducing the height dimension of the folded work platform. The same applies in reverse.

[0064] refer to Figure 5 , Figure 6 and Fig. 9 As shown, in some embodiments provided by the present invention, 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 .

[0065] The two ends of the main connecting member 103 are rotatably connected to the main upper guardrail 101 and the main lower guardrail 102, respectively, and the main upper guardrail 101 can be turned and folded inward relative to the main lower guardrail 102. For example, the main connecting member 103 can be a bent plate, and the two ends of the main connecting member 103 are respectively hinged to the main upper guardrail 101 and the main lower guardrail 102. The main lower guardrail 102 is rotatably connected to the main base 6, and the main upper guardrail 101 is detachably connected to the first main guardrail 8.

[0066] 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 turned over 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 is turned inward and folded.

[0067] refer to Figure 6 As shown, assuming that the third main guardrail 2 is an integral structure and cannot be folded in half, when the third main guardrail 2 is in a vertical state and the total height remains unchanged, when the third main guardrail 2 is flipped inward and folded, 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 increased. 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 relatively high, 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 relatively low, which 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, so that the position height of the hinge point between the second main guardrail 1 or the third main guardrail 2 and the main base 6 can be reduced, thereby reducing the height dimension of the working platform after folding.

[0068] refer to Fig. 9 and Fig.10 As shown, in some embodiments provided by the present invention, 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 .

[0069] The pair of main groove plates 10 are both connected to the side of the first main guardrail 8 close to the main base 6, that is, the main groove plates 10 are connected to the inner side of the first main guardrail 8. For example, the main groove plates 10 can be welded to the columns of the first main guardrail 8. The notches of the pair of main groove plates 10 are arranged opposite to each other, and the pair of main groove plates 10 are respectively used for the columns of the second main guardrail 1 and the third main guardrail 2 to be placed. The main limit pins 11 detachably pass through the two sides of the main groove plates 10, and are used to limit the second main guardrail 1 or the third main guardrail 2 from escaping from the main groove plates 10.

[0070] In this embodiment, when the first main guardrail 8, the second main guardrail 1 and the third main guardrail 2 are turned over and folded, the main stop pins 11 of each of the pair of main groove-shaped plates 10 are first removed, and then the second main guardrail 1 and the third main guardrail 2 are turned inward, and finally the first main guardrail 8 is turned inward. When in use, the first main guardrail 8 is first turned over and opened, and then the second main guardrail 1 and the third main guardrail 2 are turned over and opened, and the columns of the second main guardrail 1 and the columns of the third main guardrail 2 are respectively placed in the pair of main groove-shaped plates 10, and finally the main stop pins 11 are installed.

[0071] Optionally, the main limiting pin 11 may be a D-shaped pin.

[0072] In some embodiments provided by the present invention, the working platform further comprises a secondary platform, which is movably connected to the main base 6 and can move toward or away from the first main guardrail 8. Such a configuration can increase the area of ​​the working platform.

[0073] In some embodiments provided by the present invention, the secondary platform includes a secondary base 7 , a first secondary guardrail 3 , a second secondary guardrail 4 and a third secondary guardrail 5 .

[0074] 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.

[0075] The first secondary guardrail 3, the second secondary guardrail 4 and the third secondary guardrail 5 are all rotatably connected to the secondary base 7, and the first secondary guardrail 3, the second secondary guardrail 4 and the third secondary guardrail 5 are all turned inward and folded. The first secondary guardrail 3 is arranged on the side of the secondary base 7 away from the first main guardrail 8. The first secondary guardrail 3 is arranged between the second secondary guardrail 4 and the third secondary guardrail 5, and the two sides of the first secondary guardrail 3 are detachably connected to the inner side of the second secondary guardrail 4 and the inner side of the third secondary guardrail 5 respectively. The first secondary guardrail 3, the second secondary guardrail 4 and the third secondary guardrail 5 enclose a secondary accommodation space.

[0076] refer to Figure 1 As shown, when the secondary platform is in a retracted state, the secondary accommodation space is located inside the primary accommodation space, and the second secondary guardrail 4 and the third secondary guardrail 5 respectively correspond to the second primary guardrail 1 and the third primary guardrail 2. When the secondary platform is in an extended state, the secondary accommodation space is connected to the primary accommodation space, and the operator can move between the secondary accommodation space and the primary accommodation space.

[0077] refer to Figure 4As shown, further, the position height of the hinge point between the second and third auxiliary guardrails 4 and the auxiliary base 7 is smaller than the position height of the hinge point between the other and the auxiliary base 7. For example, taking the case where the position height of the hinge point between the second auxiliary guardrail 4 and the auxiliary base 7 is smaller than the position height of the hinge point between the third auxiliary guardrail 5 and the auxiliary base 7, during the folding process, the second auxiliary guardrail 4 is first flipped inwards and folded, and then the third auxiliary guardrail 5 is flipped inwards and folded. Such a setting can avoid the problem of interference between the third auxiliary guardrail 5 and the second auxiliary guardrail 4 during the flipping process, and enable the third auxiliary guardrail 5 to be placed flat on the top of the second auxiliary guardrail 4, avoiding the tilted setting of the third auxiliary guardrail 5 after folding, thereby reducing the height dimension of the folded working platform. The same applies in reverse.

[0078] refer to Fig.12 As shown, in some embodiments provided by the present invention, 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 connecting member 403 .

[0079] The two ends of the secondary connecting member 403 are rotatably connected to the secondary upper guardrail 401 and the secondary lower guardrail 402, respectively, and the secondary upper guardrail 401 can be turned and folded inward relative to the secondary lower guardrail 402. For example, the secondary connecting member 403 can be a bent plate, and the two ends of the secondary connecting member 403 are respectively connected to the secondary upper guardrail 401 and the secondary lower guardrail 402. 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.

[0080] 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 turned over 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 turned inward and folded.

[0081] In this embodiment, the second secondary guardrail 4 or the third secondary guardrail 5 can be folded in half, and the height after folding is relatively low, which can reduce the problem that the second secondary guardrail 4 or the third secondary guardrail 5 exceeds the range of the secondary base 7 after flipping, so that the position height of the hinge point between the second secondary guardrail 4 or the third secondary guardrail 5 and the secondary base 7 can be reduced, thereby reducing the height dimension of the work platform after folding. For the derivation of the beneficial effects here, reference can be made to the derivation of the beneficial effects of connecting the main upper guardrail 101 and the main lower guardrail 102 through the main connecting member 103 above. The principles of the two are similar and will not be repeated here.

[0082] refer to Fig.12 and Fig.13 As shown, in some embodiments provided by the present invention, the auxiliary platform further includes a pair of auxiliary grooved plates 12 and auxiliary positioning pins corresponding to the auxiliary grooved plates 12 .

[0083] A pair of secondary groove plates 12 are rotatably arranged on the columns on both sides of the first secondary guardrail 3, and the secondary groove plates 12 can be switched between a locked state and an unlocked state. In the locked state, the secondary groove plates 12 rotate and sleeve on the outer side of the column of the second secondary guardrail 4 or the outer side of the column of the third secondary guardrail 5. In the unlocked state, the secondary groove plates 12 rotate and open from the outer side of the column of the second secondary guardrail 4 or the outer side of the column of the third secondary guardrail 5. The secondary limiting pins 13 detachably pass through the two sides of the secondary groove plates 12 and are used to limit the second secondary guardrail 4 or the third secondary guardrail 5 from escaping from the secondary groove plates 12.

[0084] In this embodiment, when the first secondary guardrail 3, the second secondary guardrail 4 and the third secondary guardrail 5 are flipped and folded, the secondary stop pins 13 of the pair of secondary groove plates 12 are first removed, and then the pair of secondary groove plates 12 are rotated to open the pair of secondary groove plates 12 from the outside of the second secondary guardrail 4 and the outside of the third secondary guardrail 5, respectively, and then the first secondary guardrail 3 is flipped and folded inwards, and finally the second secondary guardrail 4 and the third secondary guardrail 5 are flipped and folded inwards. When in use, the second secondary guardrail 4 and the third secondary guardrail 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, and then the pair of secondary groove plates 12 are rotated, and the pair of secondary groove plates 12 are respectively sleeved on the outside of the column of the second secondary guardrail 4 and the outside of the column of the third secondary guardrail 5, and finally each secondary stop pin 13 is installed.

[0085] refer to Fig.13 As shown, optionally, the secondary trough plate 12 is sleeved on the column 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 the rotation of the secondary trough plate 12, the notch can avoid the column of the first secondary guardrail 3, thereby avoiding interference between the bottom of the trough of the secondary trough plate 12 and the column of the first secondary guardrail 3. Further, the secondary trough plate 12 can be rotatably connected to the column of the first secondary guardrail 3 by bolts.

[0086] Optionally, the secondary limiting pin 13 may be a D-shaped pin.

[0091] The first step, reference Figure 2 As shown, the mounting seat and the first main guardrail 8 are disassembled, and the mounting seat is turned inward and folded. Wherein, the mounting seat is equipped with a rotatable door body 9, and the mounting seat and the first main guardrail 8 are both rotatably connected to the main base 6.

[0092] Specifically, the mounting seat includes a pair of mounting posts 14, both of which are detachably connected to the first main guardrail 8, and there is a spacing between the pair of mounting posts 14, and the door body 9 is installed 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 turned inward and folded.

[0093] Step 2: Reference Figure 3 As shown, the first secondary guardrail 3 is detached from the second secondary guardrail 4 and the third secondary guardrail 5 respectively, and the first secondary guardrail 3 is turned inward and folded. The first secondary guardrail 3 is rotatably arranged on the side of the secondary base 7 away from the first main guardrail 8 and arranged between the second secondary guardrail 4 and the third secondary guardrail 5, and the secondary base 7 is movably connected to the main base 6.

[0094] 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 inwards.

[0095] Step 3: Reference Figure 4 As shown, the secondary upper guardrail 401 of the second secondary guardrail 4 and the third secondary guardrail 5 are turned over and folded toward the secondary lower guardrail 402, and then the secondary lower guardrail 402 is turned over and folded inward. The secondary upper guardrail 401 is rotatably connected to the secondary lower guardrail 402 through the secondary connecting member 403.

[0096] Specifically, the height of the hinge point between the second auxiliary guardrail 4 and the third auxiliary guardrail 5 and the auxiliary base 7 is smaller than the height of the hinge point between the second auxiliary guardrail 4 and the third auxiliary guardrail 5 and the auxiliary base 7 .

[0097] Step 4: Reference Figure 5-Figure 7 As shown, the second main guardrail 1 and the third main guardrail 2 are respectively disassembled from the first main guardrail 8, and the main upper guardrail 101 of the second main guardrail 1 and the third main guardrail 2 are flipped and folded toward the main lower guardrail 102, and then the main lower guardrail 102 is flipped and folded inward. Among them, the main upper guardrail 101 is rotatably connected to the main lower guardrail 102 through the main connecting member 103, and the second main guardrail 1 and the third main guardrail 2 are both arranged on the inner side of the first main guardrail 8.

[0098] Specifically, the second main guardrail 1 and the third main guardrail 2 are both rotatably connected to the main base 6, and the second main guardrail 1 and the third main guardrail 2 can be turned and folded inward. The height of the hinge point between the second main guardrail 1 and the third main guardrail 2 and the main base 6 is less than the height of the hinge point between the second main guardrail 1 and the third main guardrail 2 and the main base 6.

[0099] Step 5, Reference Figure 8 As shown, the first main guardrail 8 is turned inward and folded.

[0100] In the guardrail folding method provided in the embodiment of the present invention, the door body 9 is folded inward along with the mounting seat, thereby reducing the height of the working platform, solving or improving the defect that the folding height of the working platform in the prior art is limited by the height of the revolving door and cannot be fully folded. 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 turning them inward, the working platform can be fully folded, thereby effectively reducing the height dimension of the working platform after folding.

[0101] Further, based on the above 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.
