[0002] According to the patent document with the authorization announcement number "CN213141257U" and the invention name "A lifting mechanism for disassembling and assembling a rotor scale", its description states: When the rotor scale needs to be repaired, the lower shell is disassembled and dropped to the ground. At this time, the motor is started, and the support studs are driven to rotate through the transmission principle of the gears, so that the lifting plate drives the lower shell body to move downward along the support studs until the positioning groove is inserted into the positioning block, so that the lower shell body is plugged and positioned on the receiving plate. At this time, the lifting plate continues to move downward until it drives the fixing block out of the fixing groove, so that the lower shell body is released from the limit of the lifting plate. The lower shell body can be quickly dragged by the rollers and the receiving plate, which saves time and effort, and makes the lower shell body stable and stable when it is lifted and moved, and the operation is flexible and convenient, making it easy to disassemble and assemble the lifting plate and the receiving plate, thereby greatly saving working time and effectively improving working efficiency. When the lower shell body needs to be reset, the reverse operation can be performed, which has high efficiency, but still has the following defects:

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1, by Figure 1-7 The utility model relates to a lifting device for disassembling and assembling a rotor scale, comprising a base 1, and two lifting components 2 are symmetrically mounted on the top of the base 1;

[0027] The lifting assembly 2 includes two vertical plates 201, which are fixedly installed on the base 1. A top plate 202 is fixedly installed on the top of the two vertical plates 201. A connecting plate 203 is fixedly installed between the two vertical plates 201. The connecting plate 203 is located below the top plate 202. A longitudinal screw 204 is rotatably installed between the top plate 202 and the connecting plate 203. The bottom end of the longitudinal screw 204 is fixedly connected to the output shaft of the first motor 205. The first motor 205 is fixedly installed on the bottom end of the connecting plate 203. A longitudinal movement plate 207 is provided between the top plate 202 and the connecting plate 203. The longitudinal movement plate 207 is threadedly connected to the longitudinal screw 204. A support plate 208 is fixedly installed on the bottom end of the longitudinal movement plate 207. A supporting stabilizer 3 is installed on the support plate 208. Two guide rods 206 are symmetrically fixedly installed between the top plate 202 and the connecting plate 203. The longitudinal movement plate 207 is slidably connected to the guide rod 206.

[0028] The supporting stabilizer 3 includes two movable grooves 301 symmetrically opened inside the supporting plate 208, and a movable plate 302 is slidably installed inside the movable groove 301. A cross bar 303 is installed on the side of the two movable plates 302 away from each other. The ends of the cross bars 303 on the two movable plates 302 away from each other respectively penetrate the two sides of the supporting plate 208, and an end block 304 is fixedly installed at the end of the cross bar 303. An end support block 305 is fixedly installed on the top of the end block 304. The top wall of the end support block 305 is flush with the top wall of the supporting plate 208. A negative pressure adsorption member 4 is installed on the top of the movable groove 301. A slide groove 306 is opened inside the supporting plate 208. The slide groove 306 is connected to the two movable grooves 301. The movable plate 302 is fixed on one side close to the slide groove 306. A slide plate 307 is installed, and the slide plate 307 is slidably installed inside the slide groove 306. A double-headed screw 308 is rotatably installed inside the slide plate 307. The two slide plates 307 are respectively threadedly connected to two thread grooves on the double-headed screw 308 with opposite openings. One end of the double-headed screw 308 is fixedly connected to the output shaft of the second motor 309. The second motor 309 is fixedly installed on the support plate 208. When the second motor 309 is turned on, the double-headed screw 308 rotates. Since the two slide plates 307 are respectively threadedly connected to the two thread grooves on the double-headed screw 308 with opposite openings, the two movable plates 302 are driven away from each other, so that the end support block 305 supports the edge portion of the lower shell, thereby improving the support stability and facilitating the disassembly of rotor scales of different sizes.

[0029] The negative pressure adsorption component 4 includes two top grooves 401 symmetrically opened at the top of the support plate 208, a bottom groove 402 is opened at the bottom end of the top groove 401, and the two bottom grooves 402 penetrate into the interior of the two movable grooves 301, and a piston 403 is movably installed inside the top groove 401, and the outer wall of the piston 403 is in close contact with the inner wall of the top groove 401, and a bottom plate 404 is fixedly installed at the bottom end of the piston 403, and a slot 405 is opened on the bottom plate 404, and a pressure arc surface 406 is provided on the inner bottom wall of the slot 405, and two return springs are symmetrically installed at the bottom end of the piston 403, and the bottom end of the return spring is fixedly connected to the inner bottom wall of the top groove 401, and the bottom plate 404 is located on the side where the two movable plates 302 are close to each other. A plug plate 407 is fixedly installed on one side of the movable plate 302 close to the bottom plate 404, and the plug plate 407 is located on the inner side of the slot 405. An extrusion slope 408 is provided at one end of the plug plate 407 close to the movable plate 302. The extrusion slope 408 is inclined upward near one end of the movable plate 302, and the extrusion slope 408 is in contact with the surface of the compressed arc surface 406. In the process of the two movable plates 302 moving away from each other, the plug plate 407 is driven to move until the bottom wall of the plug plate 407 is in contact with the top wall of the compressed arc surface 406, thereby pushing the piston 403 to move downward. Since the top wall of the support plate 208 is in close contact with the bottom wall of the lower shell, a negative pressure suction force is generated inside the top groove 401, which fixes the lower shell and improves the support stability.

[0030] Working principle: When working, first turn on the first motor 205 to rotate the longitudinal screw 204. Since the longitudinal moving plate 207 is threadedly connected with the longitudinal screw 204, the support plate 208 moves upward until the top wall of the support plate 208 contacts the bottom wall of the lower shell of the rotor scale.

[0031] When the lower shell area of ​​the rotor scale is large, the second motor 309 is turned on to rotate the double-headed screw 308. Since the two slide plates 307 are respectively threadedly connected with the two thread grooves on the double-headed screw 308 with opposite directions, the two movable plates 302 are driven to move away from each other, and the two end blocks 304 are moved away from each other, so that the end support blocks 305 support the edge of the lower shell to improve the support stability.

[0032] When the two movable plates 302 move away from each other, the insert plate 407 is driven to move until the bottom wall of the insert plate 407 contacts the top wall of the pressure arc surface 406, thereby pushing the piston 403 downward under the action of pressure. Since the top wall of the support plate 208 is in close contact with the bottom wall of the lower shell, negative pressure suction is generated inside the top groove 401 to fix the lower shell and improve the support stability.

[0033] After disassembly, a reverse current is supplied to the first motor 205 to drive the support plate 208 to move downward.
