Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 3 shown, a fixed lifting device for building curtain wall processing proposed in this embodiment includes a return-shaped workbench 2. A PLC controller 3 is fixedly installed on the bottom inner wall of the return-shaped workbench 2. A curtain wall pressure control adsorption mechanism, a lifting and tilting support adjustment mechanism and a pressure control clamping and anti-falling mechanism are installed on the return-shaped workbench 2. The lifting and tilting support adjustment mechanism is used to lift and tilt the return-shaped workbench 2 according to the processing requirements;

[0026] The curtain wall pressure control adsorption mechanism includes a plurality of suction cups 401 fixedly connected to the top of the rectangular workbench 2. A vacuum pump 403 and a pressure-measuring combined pumping component fixedly connected to its air inlet are fixedly installed on the inner wall of the top of the rectangular workbench 2. The bottom ends of the plurality of suction cups 401 all extend into the rectangular workbench 2 and are fixedly connected to the top of the pressure-measuring combined pumping component. Among them, a plurality of through holes are provided on the top of the rectangular workbench 2, which are fixedly bonded to the outer bottom of the corresponding suction cups 401 respectively. The lifting and tilting adjustment mechanism, the pressure-measuring combined pumping component and the vacuum pump 403 are all electrically connected to the PLC controller 3. The pressure-measuring combined pumping component is used to synchronously suck the plurality of suction cups 401 when the vacuum pump 403 is started. By sucking, negative pressure is generated inside the suction cups 401 to adsorb and fix the building curtain wall, and the negative pressure is detected during adsorption and the negative pressure value is transmitted to the PLC controller 3. The PLC controller 3 is used to control the automatic shutdown of the vacuum pump 403 when the preset negative pressure value is reached, so as to achieve the accurate pressure control adsorption effect;

[0027] The pressure control clamping and anti-detachment mechanism includes an electric telescopic rod 5 fixedly connected to the inner wall of the top of the rectangular workbench 2 and an L-shaped plate 501 fixedly connected to the right side of the top of the rectangular workbench 2. A spring tension and pressure-measuring component fixedly connected to the extending end of the electric telescopic rod 5 is slidably sleeved on the L-shaped plate 501. The electric telescopic rod 5 and the spring tension and pressure-measuring component are both electrically connected to the PLC controller 3. The spring tension and pressure-measuring component is used to clamp and prevent detachment of the building curtain wall when the electric telescopic rod 5 starts in the reverse direction, and detect the clamping pressure and transmit the pressure value to the PLC controller 3. The PLC controller 3 is used to control the automatic shutdown of the electric telescopic rod 5 when the preset pressure value is reached, so as to achieve the accurate enhanced pressure control clamping and anti-detachment effect.

[0028] Specifically, the lifting and tilting adjustment mechanism includes a base 1 disposed below the rectangular workbench 2. On the left side of the top of the base 1, two first electric push rods 101 with their extending ends hinged to the left side of the bottom of the rectangular workbench 2 are fixedly installed. On the right side of the top of the base 1, two second electric push rods 102 are fixedly installed. The extending ends of the two second electric push rods 102 are hinged to the same slider 103. The slider 103 is slidably installed on the right side of the bottom of the rectangular workbench 2. Among them, a rectangular groove is formed on the right side of the bottom of the rectangular workbench 2. Two T-shaped guide rails 104 are fixedly connected to the inner wall of the top of the rectangular groove. Two T-shaped sliding grooves with openings on both sides are formed on the top of the slider 103. The T-shaped sliding grooves are slidably connected to the corresponding T-shaped guide rails 104, achieving the effect that the slider 103 can slide horizontally on the right side of the bottom of the rectangular workbench 2. By using the sliding connection method, the connection position with the slider 103 can be adaptively changed when the rectangular workbench 2 is tilted. The two first electric push rods 101 and the two second electric push rods 102 are all electrically connected to the PLC controller 3. With the cooperation of the set base 1, first electric push rods 101, second electric push rods 102 and slider 103, when the operator controls the two first electric push rods 101 and the two second electric push rods 102 to start synchronously through the PLC controller 3, the rectangular workbench 2 can be driven to be smoothly lifted and adjusted. When the operator controls the two second electric push rods 102 to start separately through the PLC controller 3, the two second electric push rods 102 drive the slider 103 to move upward and slide left and right on the right side of the bottom of the rectangular workbench 2. The slider 103 drives the right side of the rectangular workbench 2 to rotate upward and tilt, realizing the tilting adjustment. The lifting and tilting adjustments are used to flexibly adjust the height and slope of the building curtain wall according to the processing requirements.

[0029] Further, the pressure-measuring combined suction component includes a sub-suction box 4 fixedly connected to the inner wall of the top of the rectangular workbench 2. The right side of the sub-suction box 4 is fixedly connected to the air inlet of a vacuum pump 403. The left side of the sub-suction box 4 is fixedly connected to a solenoid valve 404. The bottom ends of a plurality of suction cups 401 are all fixedly connected to the top of the sub-suction box 4. A negative pressure sensor 402 is fixedly installed at the bottom of the sub-suction box 4. The detection end of the negative pressure sensor 402 extends into the sub-suction box 4. The negative pressure sensor 402 is electrically connected to the PLC controller 3. The arranged sub-suction box 4, solenoid valve 404, suction cups 401 and negative pressure sensor 402 cooperate. According to the negative pressure adsorption and fixation requirements, the PLC controller 3 is used to preset the negative pressure value for controlling the shutdown of the vacuum pump 403. When the vacuum pump 403 is turned on to suck the air in the sub-suction box 4, the sub-suction box 4 sucks the air in a plurality of suction cups 401, so that negative pressure is generated inside to perform the adsorption and fixation work. The negative pressure sensor 402 detects the negative pressure value in the sub-suction box 4 and transmits the negative pressure value to the PLC controller 3. When the preset negative pressure value is reached, the PLC controller 3 controls the vacuum pump 403 to automatically shut down, realizing the accurate pressure-controlled adsorption and fixation work. When releasing the adsorption state, the operator turns on the solenoid valve 404 to make the sub-suction box 4 communicate with the outside, and the negative pressure adsorption state can be released.

[0030] Further, the elastic tension pressure measuring assembly includes a lifting plate 502 slidably sleeved on the L-shaped plate 501. A rectangular guiding hole is provided at the top of the lifting plate 502 and slidably sleeved on the outer side of the corresponding L-shaped plate 501, which has the effect of guiding the vertical sliding of the lifting plate 502. The right side of the bottom of the lifting plate 502 is fixedly connected to the extending end of the electric telescopic rod 5. A pressure sensor 505 electrically connected to the PLC controller 3 is fixedly embedded on the left side of the bottom of the lifting plate 502. Two springs 506 are fixedly connected to the bottom of the pressure sensor 505. The bottom ends of the two springs 506 are fixedly connected to the same pressing block 503. Four T-shaped guiding rods 504 are fixedly connected to the top of the pressing block 503 in a rectangular shape. The lifting plate 502 is slidably sleeved on the four T-shaped guiding rods 504. A rectangular shape is provided at the top of the lifting plate 502 with four vertical guiding holes respectively slidably sleeved on the outer sides of the corresponding T-shaped guiding rods 504, which has the effect of guiding the vertical sliding of the T-shaped guiding rods 504. Anti-slip rubber pads 507 are adhesively fixed on the bottom of the pressing block 503 and the inner wall of the bottom of the L-shaped plate 501. The top position of the suction cup 401 is flush with the top position of the lower anti-slip rubber pad 507. The cooperation of the provided lifting plate 502, pressure sensor 505, springs 506, pressing block 503 and T-shaped guiding rods 504 is used to preset and control the closing pressure value of the electric telescopic rod 5 by the PLC controller 3 according to the clamping force requirement. When the electric telescopic rod 5 is reversely started to drive the lifting plate 502 to move downward, the lifting plate 502 drives the pressing block 503 to press down on the top side of the building curtain wall through the pressure sensor 505 and the springs 506 in sequence. In the pressing state, the pressing block 503 is blocked and restricted. At this time, the pressure sensor 505 that continues to move downward compresses the springs 506, gradually turning it into a hard-state support. The pressure sensor 505 detects the applied extrusion force and transmits the pressure value to the PLC controller 3. When the preset pressure value is reached, the PLC controller 3 controls the electric telescopic rod 5 to automatically close, achieving the effect of precise pressure control for clamping and anti-loosening, reducing the risk of the building curtain wall tilting and sliding to one side during the inclined support after the inclination adjustment. The provided anti-slip rubber pads 507 are used to enhance the anti-slip performance during clamping.

[0031] The usage method of this embodiment is as follows: When in use, place the building curtain wall to be processed on the tops of multiple suction cups 401 and insert its right side into the L-shaped plate 501. At this time, the bottom right side of the building curtain wall is in contact with the top of the lower anti-slip rubber pad 507. Personnel preset and control the closing negative pressure value of the vacuum pump 403 by the PLC controller 3 according to the negative pressure adsorption and fixation requirement in advance. When the vacuum pump 403 is turned on to suck the sub-suction box 4, the sub-suction box 4 sucks multiple suction cups 401, generating negative pressure inside for the adsorption and fixation work. The negative pressure sensor 402 detects the negative pressure value in the sub-suction box 4 and transmits the negative pressure value to the PLC controller 3. When the preset negative pressure value is reached, the PLC controller 3 controls the vacuum pump 403 to automatically close, achieving the precise pressure control for adsorption and fixation work, and improving the accuracy of adsorption and fixation through the method of pressure control for adsorption and fixation.

[0032] In addition, personnel preset the closing pressure value for controlling the electric telescopic rod 5 in advance according to the clamping force requirement by using the PLC controller 3, and reversely start the electric telescopic rod 5 to drive the lifting plate 502 to slide downward on the L-shaped plate 501. The lifting plate 502 drives the pressing block 503 to move downward through the pressure sensor 505 and the spring 506 in sequence. The pressing block 503 drives the anti-slip rubber pad 507 above to press downward on one side of the top of the building curtain wall, cooperating with the anti-slip rubber pad 507 below to form a clamping state. And in the pressing state, the pressing block 503 is blocked and restricted. At this time, the continuously descending lifting plate 502 slides downward on the four T-shaped guide rods 504. At this time, the continuously descending pressure sensor 505 compresses the spring 506, gradually transforming it into a hard-state support. The pressure sensor 505 detects the applied extrusion force and transmits the pressure value to the PLC controller 3. When the preset pressure value is reached, the PLC controller 3 controls the electric telescopic rod 5 to automatically close, achieving the effect of precise pressure control, clamping, and anti-loosening. By using the combined method of pressure control clamping and anti-loosening and pressure control adsorption, the building curtain wall can be effectively fixed stably and prevent loosening, reducing the risk of the building curtain wall slipping smoothly or obliquely during operations such as tilting, machining, grinding, and scraping, and improving the use stability;

[0033] During lifting and adjustment, personnel operate the two first electric push rods 101 and the two second electric push rods 102 to start synchronously through the PLC controller 3. At this time, the two first electric push rods 101 and the two second electric push rods 102 can drive the loop-shaped workbench 2 to lift smoothly for adjustment work. During tilting adjustment, personnel operate the two second electric push rods 102 to start individually through the PLC controller 3. The two second electric push rods 102 drive the slider 103 to move upward and slide left and right on the two T-shaped guide rails 104. The slider 103 drives the right side of the loop-shaped workbench 2 to rotate upward and tilt through the two T-shaped guide rails 104, realizing tilting adjustment. By using lifting and tilting adjustment, it is convenient to flexibly adjust the height and slope of the building curtain wall according to processing requirements. Compared with single lifting adjustment, the flexibility of support adjustment is improved;

[0034] After use, when it is necessary to release the adsorption and fixation, personnel open the solenoid valve 404, so that the sub-extraction box 4 is communicated with the outside through the solenoid valve 404, and the negative pressure adsorption and fixation state can be released. Then, start the electric telescopic rod 5 forward to drive the lifting plate 502 to move upward and back. The lifting plate 502 drives the pressure sensor 505 to relax the compression force on the spring 506 upward. After the compression force is released, the continuously upward moving pressure sensor 505 drives the pressing block 503 to release the pressing work through the spring 506, and the building curtain wall can be removed.

[0035] Among them, the PLC controller 3, vacuum pump 403, negative pressure sensor 402, electric telescopic rod 5 and pressure sensor 505 in the present utility model are well-known to those skilled in the art, belonging to conventional means or common general knowledge. Those skilled in the art can make arbitrary selections according to their needs or convenience. In addition, using the PLC controller 3 to receive the negative pressure value transmitted by the negative pressure sensor 402 and control the vacuum pump 403 to close when the preset value is reached, and receiving the pressure value transmitted by the pressure sensor 505 and controlling the electric telescopic rod 5 to close when the preset value is reached are basic programming numerical control methods well-known to those skilled in the art, all belonging to conventional means or common general knowledge, and will not be elaborated herein.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
