[0061] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0062] The following is combined with Figure 1-8 The lifting work platform 100 according to the embodiment of the present invention is described.

[0063] like Figure 1 As shown, the lifting work platform 100 of the embodiment of the present invention includes a base 1, a multi-scissor lift platform 2 and a connecting plate 3. The multi-scissor lift platform 2 is arranged on the base 1. The base 1 has a plug-in hole 101 running through it along the front-to-back direction. Correspondingly, the side of the connecting plate 3 close to the multi-scissor lift platform 2 is provided with a plug-in rod 4 extending along the front-to-back direction, and the plug-in rod 4 can be plugged into the plug-in hole 101.

[0064] At the same time, the side of the connecting plate 3 away from the multi-scissor lift platform 2 is suitable for being connected to the transport equipment, so as to facilitate the installation of the connecting plate 3 on the transport equipment.

[0065] At the same time Figure 4 As shown, limit plates 5 are provided at positions adjacent to the two end ports in the plug hole 101, and limit holes 501 are provided on the limit plates 5. The diameter of the limit holes 501 is the same as the diameter of the plug rod 4, so that when the plug rod 4 is inserted into the limit holes 501, the plug hole 101 can be avoided. The two limit plates 5 define a first chamber 6 in the plug hole 101, and an air bag 7 is provided in the first chamber 6 to fix the plug rod 4 by expansion and compression.

[0066] Therefore, when the multi-scissor lift assembly needs to be installed on the transport equipment, the connecting plate 3 is first installed and fixed on the transport equipment, and then the plug-in rod 4 of the connecting plate 3 is inserted into the plug-in hole 101 of the base 1 through the limiting hole 501 of the limiting plate 5, and the air bag 7 is inflated by an air pump so that the air bag 7 expands and squeezes the plug-in rod 4. A huge friction force can be generated between the air bag 7 and the plug-in rod 4, thereby achieving the effect of fixing the plug-in rod 4 in the plug-in hole 101, thereby realizing the installation of the multi-scissor lift assembly on the transport equipment.

[0067] When the multi-scissor lift assembly needs to be disassembled from the transport equipment, the gas in the airbag 7 is released to reduce the volume of the airbag 7, thereby reducing the friction between the airbag 7 and the plug-in rod 4. The plug-in rod 4 of the connecting plate 3 can be pulled out of the plug-in hole 101, thereby achieving the effect of disassembling the multi-scissor lift assembly from the transport equipment.

[0068] The lifting work platform 100 of the embodiment of the present invention is provided with a front-to-back plug-in hole 101 on the base 1, a plug-in rod 4 suitable for being plugged into the plug-in hole 101 is provided on the connecting plate 3, and an air bag 7 is provided in the plug-in hole 101, so that the multi-scissor lift assembly can be easily installed and disassembled.

[0069] The following is combined with Figure 1-8 The lifting work platform 100 according to the embodiment of the present invention is further described.

[0070] The lifting work platform 100 of the embodiment of the present invention includes a base 1, a multi-scissor lift platform 2 and a connecting plate 3.

[0071] It can be understood that the multi-scissor lift platform 2 includes a plurality of scissor lift assemblies connected in sequence in the up and down directions, a workbench 201 is provided on the scissor lift assembly at the uppermost end, and a fence 2011 is provided on the outer edge of the workbench 201 to protect the safety of the operators. At the same time, the multi-scissor lift platform 2 can be driven to rise and fall by a hydraulic cylinder or an electric push rod. The specific driving method belongs to the prior art and will not be described in detail here.

[0072] like Figure 2 As shown, the multi-scissor lift platform 2 is arranged on a base 1, and the base 1 has a plug-in hole 101 penetrating therethrough in the front-to-back direction. A plug-in rod 4 extending in the front-to-back direction is arranged on the side of the connecting plate 3 close to the multi-scissor lift platform 2, and the plug-in rod 4 is plugged into the plug-in hole 101. The side of the connecting plate 3 away from the multi-scissor lift platform 2 is suitable for being connected to the transportation equipment.

[0073] It can be understood that the transportation equipment here can be a loader 200, a forklift and other transportation equipment. By connecting the transportation equipment with the connecting plate 3, it is convenient for the transportation equipment to transport the lifting work platform 100 of the embodiment of the present invention to the work site.

[0074] Limiting plates 5 are disposed in the plug hole 101 adjacent to the ports at both ends thereof. The limiting plates 5 are provided with limiting holes 501 . The diameter of the limiting holes 501 is the same as the diameter of the plug rod 4 .

[0075] It can be understood that the axes of the limiting holes 501 on the limiting plates 5 adjacent to the ports at both ends of the plug hole 101 coincide with each other, so that the plug rod 4 can smoothly pass through the limiting hole 501 .

[0076] At the same time, the two limiting plates 5 define a first chamber 6 in the plug-in hole 101 , and an air bag 7 is arranged in the first chamber 6 to fix the plug-in rod 4 by expansion and compression.

[0077] It can be understood that in order to facilitate the inflation of the airbag 7, the airbag 7 can be connected to an air pump, and in order to facilitate the deflation of the airbag 7, the airbag 7 can be connected to a valve. When the airbag 7 needs to be deflated, the valve can be opened, and when the airbag 7 does not need to be deflated, the valve can be closed.

[0078] When the multi-scissor lift assembly needs to be installed on the transport equipment, the plug-in rod 4 is fixed in the plug-in hole 101, and after the plug-in rod 4 is inserted into the plug-in hole 101 through the limit hole 501, the airbag 7 is inflated by an air pump to expand the volume of the airbag 7, so that the airbag 7 and the plug-in rod 4 are abutted and squeezed against the plug-in rod 4, and a huge friction force is generated between the airbag 7 and the plug-in rod 4. As a result, the plug-in rod 4 of the connecting plate 3 is fixed in the plug-in hole 101, thereby achieving the effect of installing the multi-scissor lift assembly on the transport equipment.

[0079] When the multi-scissor lift assembly needs to be disassembled from the transport equipment, the gas in the airbag 7 is released by an air pump to reduce the volume of the airbag 7, thereby reducing the friction between the airbag 7 and the plug-in rod 4. The plug-in rod 4 can be pulled out of the plug-in hole 101, thereby the multi-scissor lift assembly can be disassembled from the connecting plate 3, thereby achieving the effect of disassembling the multi-scissor lift assembly from the transport equipment.

[0080] It can be understood that in order to facilitate the control of the pressure in the airbag 7, an air pressure sensor 10 can be set in the airbag 7 to monitor the pressure of the airbag 7 by collecting the air pressure in the airbag 7 in real time. For example, when the pressure in the airbag 7 reaches a first preset value, inflating the airbag 7 is stopped; when the pressure in the airbag 7 reaches a second preset value, deflating the airbag 7 is stopped.

[0081] The first preset value can be determined based on whether the friction force generated between the airbag 7 and the connector is sufficient to fix the connector in the connector hole 101;

[0082] The second preset value can be determined based on whether the friction force generated between the airbag 7 and the connector is sufficient to pull the connector out of the connector hole 101 .

[0083] The lifting work platform 100 of the embodiment of the present invention is provided with a front-to-back plug-in hole 101 on the base 1, and a plug-in rod 4 suitable for being plugged into the plug-in hole 101 is provided on the connecting plate 3. At the same time, an air bag 7 that can fix the plug-in rod 4 by expansion and compression is provided in the plug-in hole 101, so that the multi-scissor lift assembly can be installed and disassembled more conveniently.

[0084] In some embodiments, the airbag 7 is a cylindrical airbag 7 and there are multiple of them, and the multiple cylindrical airbags 7 are arranged at intervals along the circumference of the first chamber 6.

[0085] like Figure 5As shown, there are four cylindrical airbags 7 , and the four cylindrical airbags 7 are arranged at intervals around the circumference of the first chamber 6 .

[0088] Optionally, the anti-slip member 8 can be arranged on a side of the airbag 7 adjacent to the plug rod 4 corresponding to the anti-slip groove 401 of the plug rod 4, and the anti-slip member 8 can be fitted in the anti-slip groove 401 to limit the movement of the plug rod 4, thereby achieving the effect of fixing the plug rod 4.

[0089] The lifting work platform 100 of the embodiment of the present invention can further fix the plug rod 4 in the plug hole 101 by providing an anti-skid groove 401 on the plug rod 4 and an anti-skid member 8 on the cylindrical airbag 7 that can fit in the anti-skid groove 401 .

[0090] In some embodiments, different from the above embodiments, the airbag 7 is a cylindrical airbag 7 , and the cylindrical airbag 7 has a first through hole 701 , and the first through hole 701 penetrates the cylindrical airbag 7 along the axial direction of the cylindrical airbag 7 .

[0093] Optionally, the anti-slip parts 8 are divided into multiple groups, and the multiple groups of anti-slip parts 8 are arranged on the inner wall of the first through hole 701 at intervals in the axial direction of the cylindrical airbag 7. At the same time, multiple anti-slip parts 8 in each group of anti-slip parts 8 are arranged on the inner wall of the first through hole 701 at intervals along the circumferential direction of the cylindrical airbag 7. The anti-slip parts 8 can be fitted in the anti-slip groove 401 to limit the movement of the plug-in rod 4, thereby achieving the effect of fixing the plug-in rod 4.

[0094] like Figure 7 As shown, a group of anti-slip members 8 consists of six anti-slip members 8 , which are arranged on the inner wall of the first through hole 701 at intervals along the circumference of the cylindrical airbag 7 .

[0095] The lifting work platform 100 of the embodiment of the present invention can further fix the plug rod 4 in the plug hole 101 by providing an anti-skid groove 401 on the plug rod 4 and an anti-skid member 8 on the cylindrical airbag 7 that can fit in the anti-skid groove 401 .

[0096] In some embodiments, a transition piece 9 is provided on one side of the limiting plate 5 close to the connecting seat. The transition piece 9 has a transition hole 901 connected to the limiting hole 501 , and the diameter of the transition hole 901 gradually increases in a direction close to the connecting seat.

[0097] Optionally, the maximum diameter of the transition hole 901 is equal to the diameter of the plug hole 101 , and the minimum diameter of the transition hole 901 is equal to the diameter of the limiting hole 501 .
