[0034] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] As Figure 1 shown, an aerial work platform according to an embodiment of the present utility model can be transported to a high altitude so that the staff located on the aerial work platform can perform aerial work. The aerial work platform includes a platform main body 100 and a support frame 200.

[0036] The platform main body 100 includes a workbench 110 and a guardrail 120 connected to the workbench 110.

[0037] It can be understood that the workbench 110 can provide a standing position for the staff, while the guardrail 120 is used for protection to reduce the risk of the staff falling from the workbench 110.

[0038] Specifically, the guardrail 120 is connected to the periphery of the workbench 110 and is located above the workbench 110. When the staff stands on the workbench 110, the guardrail 120 surrounds the staff and plays a protective role for the staff.

[0039] It should be noted that the platform main body 100 is not limited to providing a standing position for the staff. The platform main body 100 can also provide a placement position for other objects. Of course, in some cases, the platform main body 100 can also be used to transport objects only.

[0040] Among them, rollers 300 may be provided at the bottom of the workbench 110, and the rollers 300 may be universal wheels, so that the aerial work platform can be easily moved on the ground.

[0041] Combined Figure 1 with Figure 2 , the support frame 200 is connected to the bottom of the workbench 110, and the support frame 200 has a working position ( Figure 2 the position where the support frame 200 is located in ). When the support frame 200 is in the working position, at least a part of the support frame 200 extends from the side of the workbench 110 to be used as a support structure for supporting objects, and the object can lean on the guardrail 120 when being supported on the support structure.

[0042] It can be understood that when the support frame 200 is in the working position, the support frame 200 is equivalent to expanding the side space of the platform main body 100 to assist in carrying some objects. And when some objects are placed on the support frame 200, they can also lean on the guardrail 120, which is beneficial to improving safety.

[0043] Furthermore, the support frame 200 is movably connected to the bottom of the workbench 110, and the support frame 200 also has a non-working position ( Figure 1 the position where the support frame 200 is located in ). The support frame 200 can be operably switched between the working position and the non-working position; when the support frame 200 is in the non-working position, the support frame 200 retracts below the platform main body 100.

[0044] It can be understood that when the support frame 200 is in the non-working position, the support frame 200 retracts below the platform main body 100, which can reduce the occupied space of the support frame 200 on the side of the workbench 110. By pulling the support frame 200, the support frame 200 can be moved from the non-working position to the working position for use.

[0045] Among them, the moving direction of the support frame 200 moving from the non-working position to the working position is defined as the preset direction.

[0046] Combined Figure 2 with Figure 3 , the support frame 200 includes a support portion 210 and a limiting portion 220. The support portion 210 includes a first end 210a and a second end 210b oppositely arranged to the first end 210a. The limiting portion 220 is connected to the second end 210b, and the limiting portion 220 extends upward from the support portion 210. The limiting portion 220 is used to limit the object supported on the support portion 210 from sliding off the second end 210b along the horizontal direction; among them, the arrangement direction from the first end 210a to the second end 210b is parallel to the preset direction.

[0047] It can be understood that when the support part 210 is in the working position, the limiting part 220 extends out from the side of the workbench 110. At this time, when a plate-like object such as glass or a wooden board is placed on the support part 210, the bottom end of the object can be limited by the limiting part 220, and the top end of the object can lean against the guardrail 120. In this way, the object can be placed more stably, reducing the risk of the object falling.

[0048] Among them, a hand-holding position 221 is arranged on the limiting part 220, which is convenient for the staff to pull and draw the support frame 200.

[0049] As Figure 2 shown, it should be noted that a hanging ring 121 can be arranged on the guardrail 120. In this way, a rope can pass through the hanging ring 121 and tie the object, thereby further reducing the risk of the object falling and having high safety.

[0050] Combined with Figure 3 、 Figure 6 and Figure 7 , it should be noted that a conduit 130 is arranged at the bottom of the platform main body 100, and the support frame 200 is slidably arranged in the conduit 130. In this way, the support frame 200 can be switched between the working position and the non-working position.

[0051] Specifically, two conduits 130 arranged in parallel and at intervals are arranged at the bottom of the workbench 110. The support frame 200 has two support rods 211 arranged in parallel and at intervals. One ends of the two support rods 211 are connected by the limiting part 220, and the two support rods 211 are respectively arranged in the two conduits 130 in a one-to-one correspondence.

[0052] Among them, the conduit 130 can be a square tube, and the support rod 211 is also a square rod. Of course, in other embodiments, the conduit 130 and the support rod 211 can also be of other shapes.

[0053] Combined with Figure 4 and Figure 7 , it should be noted that a wear-resistant part 240 is arranged on the support frame 200, and the wear-resistant part 240 is in sliding fit with the inner wall of the conduit 130. The support frame 200 slides in cooperation with the inner wall of the conduit 130 by means of the wear-resistant piece, which can reduce the risk of the support frame 200 being worn and extend the service life of the support frame 200.

[0054] Specifically, a plurality of wear-resistant parts 240 are arranged on the support rod 211, and the plurality of wear-resistant parts 240 are arranged around the axis of the support rod 211. The wear-resistant part 240 can prevent the support frame 200 from directly contacting the inner wall of the conduit 130.

[0055] Combined with Figure 3 and Figure 5, in some embodiments, one of the catheter 130 and the support frame 200 is provided with a travel limiting hole 212, and the other is connected with a travel limiting member 230 inserted into the travel limiting hole 212; wherein, the length direction of the travel limiting hole 212 is parallel to the length direction of the catheter 130.

[0056] Specifically in this embodiment, the support frame 200 is provided with a travel limiting hole 212, and a travel limiting member 230 is connected to the catheter 130. The travel limiting member 230 is inserted into the travel limiting hole 212, so that the moving stroke of the support frame 200 can be limited to prevent the support frame 200 from directly sliding off the workbench 110.

[0057] Specifically, the bottom end of the support frame 200 is provided with a travel limiting hole 212. The travel limiting hole 212 is elongated, and the length direction of the travel limiting hole 212 is parallel to the length direction of the catheter 130; the travel limiting member 230 is a pin, and a pin hole is provided at the bottom of the catheter 130. The pin is inserted into the pin hole and then into the travel limiting hole 212.

[0058] Combined Figure 4 with Figure 7 , in some embodiments, a trigger member 250 is further provided on the support frame 200, and a position sensor 140 is provided on the workbench 110. When the support frame 200 is in a non-working position, the position sensor 140 is triggered by the trigger member 250.

[0059] Specifically, the aerial work platform further includes a controller and a weighing sensor provided on the workbench 110. The position sensor 140 and the weighing sensor are both electrically connected to the controller. The weighing sensor is used to detect the weight carried by the workbench 110. When the position sensor 140 is triggered by the trigger member 250, that is, when the support frame 200 is in a non-working position, the controller limits the weight that the workbench 110 can carry to a first limit weight. When the support frame 200 is in a working position, the controller limits the weight that the workbench 110 can carry to a second limit weight, wherein the first limit weight is greater than the second limit weight.

[0060] It can be understood that the weighing sensor is only used to detect the weight carried by the workbench 110, and does not detect the weight carried by the support frame 200. When the support frame 200 is in a non-working position, only the workbench 110 is used for carrying. When the support frame 200 is in a working position, since the support frame 200 also needs to carry objects, at this time, it is necessary to reduce the weight limit that the workbench 110 can carry. In this way, overweight can be avoided.

[0061] It should be noted that the number of the position sensors 140 is set to be multiple, and the number of the trigger members 250 is also set to be multiple. When the support frame 200 is in the non-working position, the multiple position sensors 140 can be triggered one by one by the multiple trigger members 250. In this way, when one of the position sensors 140 is damaged, the other position sensors 140 can still function.

[0062] It should be noted that the position sensor 140 can be a travel switch or a proximity switch.

[0063] As Figure 6 shown, in some embodiments, the aerial work platform further includes a locking member 260, and the locking member 260 detachably locks the support frame 200 in the non-working position.

[0064] Specifically, the workbench 110 is provided with a first positioning hole, and the support frame 200 is provided with a second positioning hole. When the support frame 200 is locked in the non-working position, the first positioning hole and the second positioning hole are oppositely arranged, and the locking member 260 can be inserted through the first positioning hole and the second positioning hole in a pull-out manner when the support frame 200 is in the non-working position.

[0065] In this way, when the support frame 200 is in the non-working position, the support frame 200 can be locked by means of the locking member, avoiding the support frame 200 sliding out due to other factors and affecting the normal operation of the staff.

[0066] Among them, the locking member 260 can be connected to the workbench 110 by means of a chain or a rope, reducing the risk of loss of the locking member 260.

[0067] Certainly, in other embodiments, the support frame 200 in the non-working position can also be locked by means of a magnet.

[0068] In the aerial work platform of the present utility model, the workbench 110 can provide a standing space for the staff, and the guardrail 120 is used for protection, reducing the risk of the staff falling from the workbench 110. When the support frame 200 is in the working position, the support frame 200 is equivalent to expanding the side space of the platform main body 100, assisting in carrying some objects. And, when some objects are placed on the support frame 200, they can also lean on the guardrail 120, which is beneficial to improving safety. In addition, for some large plate members, such as glass, wooden boards and other products, they can be placed on the support frame 200 in the working position and are not restricted by the space of the guardrail 120.

[0069] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0070] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
