[0035] The upper end surface of the top plate 4 is provided with fixing components 5 at the corners around it, and the middle of the upper end surface of the top plate 4 is fixedly connected with a fixing plate 6. Four groups of steel wire ropes for lifting are respectively connected through the fixing components 5 and the fixing plate 6, so that the lifting force of the lifting device is uniform.

[0036] The fixing assembly 5 includes a sleeve 54 fixedly connected to the top plate 4, the top of the sleeve 54 is movably connected to the upper fixing plate 51, the inside of the sleeve 54 is movably connected to a guide column 52 of a T-shaped structure, and the top of the guide column 52 passes through the sleeve 54 and is connected and fixed to the upper fixing plate 51.

[0037] An airbag 53 is arranged inside the sleeve 54, and the airbag 53 is designed as an annular columnar structure and is sleeved on the outside of the guide column 52. An air pipe 73 is fixedly connected to the outside of the sleeve 54. The air pipe 73 is connected to the airbag 53, and the other end of the air pipe 73 is connected to the clamping assembly 7.

[0038] The lower end surface of the side plate 1 is fixedly connected with a buffer airbag 8, the lower end of the air pipe 73 is also connected to the buffer airbag 8, and a pressure valve is built-in at the connection between the air pipe 73 and the buffer airbag 8.

[0039] The clamping assembly 7 includes a cylinder 74 symmetrically distributed on the side plate 1, and one half of the cylinder 74 is embedded in the inside of the side plate 1. A connecting column 72 passes through the inside of the cylinder 74 and is movably connected. The connecting column 72 is designed to be T-shaped and matches the cylinder 74. A spring 75 is fixed between the connecting column 72 and the cylinder 74.

[0040] One end of the connection column 72 away from the spring 75 is fixedly connected to a clamping plate 71 , a rubber anti-skid pad is glued to the side of the clamping plate 71 , and the bottom of the clamping plate 71 is designed to fit the bottom plate 3 .

[0041] The bottom of the side panel 1 is designed in an L-shaped structure. The two sides of the bottom panel 3 are fixedly connected with the adjacent surfaces of the side panel 1, and the outer sleeve of the rotation shaft 32 is fixed with a bearing 33. The ends of the rotation shaft 32 and the bearing 33 are embedded and connected inside the side panel 1. The lower end surface of the door panel 2 is symmetrically fixed with a guide rail 21, and the guide rail 21 penetrates the top panel 4 and is slidably connected with the inner wall of the side panel 1. The upper end surface of the bottom panel 3 and the bottom of the guide rail 21 are provided with a plug-in hole groove 31 at a position corresponding to the bottom of the guide rail 21, and the lower end surface of the bottom panel 3 is provided with an arc-shaped snap-in groove 34 at equal distances, and the snap-in groove 34 is glued with an anti-slip rubber pad.

[0042] If the hoisted object is a columnar object, the user can first lift the device to a certain height off the ground through a wire rope, and then push the bottom guide rail 21 of the door panel 2 upward to disengage the bottom of the guide rail 21 from the plug-in hole groove 31 on the bottom plate 3. At this time, the user can manually reverse the bottom plate 3, and reverse the lower end surface of the bottom plate 3 to the upper side through the rotating shaft 32 and the bearing 33. The arc-shaped snap-fit ​​groove 34 on the bottom plate 3 is located on the upper side. In this way, the columnar tubular objects are fixed through the snap-fit ​​groove 34 to prevent the objects from rolling during the lifting process. The design of this structure can meet the lifting and transportation work of most objects and maintain stability during the lifting process.

[0043] Working principle: When working, first place the lifting device at a suitable position on the ground, then fix one end of the wire rope used for lifting to the upper fixing plate 51 in the fixing assembly 5 and to the fixing plate 6, and connect the other end of the wire rope to the lifting device, then place the object between the side panels 1 and the upper end surface of the bottom plate 3. If the object to be lifted is a columnar object, the user can first lift the device to a certain height off the ground by the wire rope, and then push the bottom guide rail 21 of the door panel 2 upwards to disengage the bottom of the guide rail 21 from the plug-in slot 31 on the bottom plate 3. At this time, use The user can manually reverse the bottom plate 3, and the lower end surface of the bottom plate 3 is reversed to the upper side through the rotating shaft 32 and the bearing 33. The arc-shaped snap-fitting groove 34 on the bottom plate 3 is located on the upper side. In this way, the cylindrical tubular objects are snap-fitted and fixed through the snap-fitting groove 34 to prevent the objects from rolling during the lifting process. The design of this structure can meet the lifting and transportation work of most objects and maintain the stability during the lifting process. Then, when the objects are loaded, the lifting equipment pulls the fixing assembly 5 up through the wire rope, and then lifts the device itself. At this time, the door panel 2 is moved down and plugged into the guide rail 21 under the action of its own gravity. The bottom plate 3 is fixed inside the plug-in hole groove 31, and the door panel 2 moves down to close the front and rear openings of the device. The two door panels 2 and the two side panels 1 can make the device seal the internal hoisting materials to prevent them from falling during the hoisting process. When the wire rope pulls the upper fixing plate 51 upward, the upper fixing plate 51 drives the guide column 52 to move upward, thereby compressing the air bag 53 inside the sleeve 54. At this time, the gas inside the air bag 53 is further transported to the cylinder 74 in the clamping assembly 7 through the air pipe 73. At this time, the connecting column 72 and the clamping plate 71 are pushed toward each other under the action of the gas pressure. Movement, clamping, wrapping and fixing the items between the two clamping plates 71, the displacement of the connecting column 72 will pull the spring 75, and the clamping plate 71 can be reset by the spring 75 later, and when the clamping plate 71 contacts the item and clamps it and cannot be displaced, the gas in the air pipe 73 breaks through the pressure valves and is transported to the buffer airbag 8, and the buffer airbag 8 expands and becomes larger. The design purpose of the buffer airbag 8 is to temporarily store excess gas transported to the air pipe 73 to avoid the air pipe 73 from bursting. At the same time, when the device falls and contacts the ground, it can also buffer the contact force with the ground to avoid damage to the bottom plate 3 from hard collision with the ground.
