Since a part of the wall will be reserved when the doors and windows are installed, and then the doors and windows are buried in the reserved wall, it is necessary to adjust the height of the first hanging arm 202 when assembling the lifting equipment. First, the mounting frame 1 is moved to a suitable position, and then the first hanging arm 202 is connected to the mounting seat 201 at the bottom of the mounting frame 1 through the connecting shaft, and then the second hanging arm 203 is inserted into the internal cavity of the first hanging arm 202, and the total length of the first hanging arm 202 and the second hanging arm 203 is adjusted to a suitable size, and then the first hanging arm 202 and the second hanging arm 203 are fixed by the latch, and then the limiting rods 207 on both sides of the slide 206 are squeezed inwardly, and then the two limiting rods 207 slide toward the inside of the second hanging arm 203 and compress the first spring 209. At the same time, the limiting rod 207 drives the limiting block 208 at the end to disengage from the limiting groove 205 inside the second hanging arm 203, and then the slide 206 is moved back and forth to make the slide The limiting rod 207 on 206 slides forward and backward along the slide groove 204, at which time the slide 206 drives the support frame 210 fixed at the bottom to move forward and backward, and the support frame 210 drives the first rotating wheel 211 to roll on the ground. When the slide 206 moves to a suitable position, the two limiting rods 207 are released, and then the limiting rod 207 and the limiting block 208 at its end are driven to move toward the outside of the second hanging arm 203 under the reset action of the first spring 209, until the limiting block 208 is engaged with another limiting groove 205 inside the second hanging arm 203, thereby effectively limiting the slide 206, avoiding relative sliding between the slide 206 and the second hanging arm 203 during the process of hanging doors and windows, and improving stability. At this time, the inclination angle between the first hanging arm 202 and the mounting frame 1 is adjusted by changing the distance between the supporting frame 210 and the end of the second hanging arm 203, so as to adapt to cement walls of different heights at the edge of the floor, and the flexibility is strong. ;

[0037] Specifically, Figure 1 , Figure 2 and Figure 4As shown, the auxiliary structure 3 includes a first slide bar 301 and a second slide bar 302 slidably connected to the inside of the first slide bar 301, the front end of the second suspension arm 203 is fixedly connected to the two first slide bars 301, the top surface of the second slide bar 302 is provided with a plurality of limiting holes 303, the end of the first slide bar 301 is threadedly connected to a knob 304, the bottom of the knob 304 is engaged with the limiting hole 303, the end of the second slide bar 302 is rotatably connected to a first rotating shaft 305, the first rotating shaft 305 is fixedly connected to a second rotating shaft 306, and the first rotating shaft 306 is fixedly connected to a second rotating shaft 307. The front end of the second hanging arm 203 is rotatably connected to the second rotating shaft 307, the middle of the second rotating shaft 307 is fixedly connected to the first guide wheel 308, and the two ends of the second rotating shaft 307 are respectively fixedly connected to a third rotating wheel 309, the two first sliding rods 301 are symmetrically arranged, and the two second sliding rods 302 are both in an "L" shape structure; to avoid the problem of damage to the door and window due to local force when pulling the door and window to the end of the second hanging arm 203, just turn the knob 301 at the end of the first sliding rod 301 to 4, then pull the two second slide bars 302 outward, and then control the distance of pulling the second slide bars 302 outward according to the size of the door and window. When the two second slide bars 302 are pulled outward to a suitable length, tighten the knob 304 in the opposite direction to make the bottom of the knob 304 engage with the limiting hole 303 at the top of the second slide bar 302, thereby completing the fixation of the second slide bar 302 with strong stability. Then, when lifting the door and window upward, the two motors 7 on the mounting frame 1 drive the middle pay-off wheel 8 to rotate, and then the pay-off wheel 8 retracts the wire rope, and the second lifting arm 2 03 The first guide wheel 308 at the front end is rotated by the second rotating shaft 307, and the wire rope is turned by the first guide wheel 308. When the wire rope pulls the doors and windows to the third rotating wheels 309 at both ends of the second rotating shaft 307, the bottom surfaces of the doors and windows simultaneously contact the second rotating wheels 306 at the end of the second sliding rod 302, and the second rotating wheels 306 are rotated by the first rotating shaft 305, thereby reducing the friction between the second rotating wheels 306 and the doors and windows, making it easy to quickly pull the doors and windows into the room, with simple operation and strong flexibility, and can effectively prevent damage to the doors and windows.

[0038] Specifically, Figure 1 , Figure 5 , Figure 8 and Fig.10As shown, the adjustment structure 4 includes a mounting block 401 and a screw rod 402 threadedly connected to the mounting block 401, two mounting blocks 401 are fixedly connected to the bottom of the front side of the mounting frame 1, the bottom end of the screw rod 402 is rotatably connected to a mounting plate 404, the bottom end of the mounting plate 404 is fixedly connected to a universal wheel 405, the bottom of the rear side of the mounting frame 1 is fixedly connected to another two universal wheels 405, and the top of the screw rod 402 is fixedly connected to a rotating handle 403; when the ground where the lifting equipment is placed is uneven, it is only necessary to rotate the screw rod 402 by rotating the handle 403. Due to the threaded connection between the screw rod 402 and the mounting block 401, the screw rod 402 drives the mounting plate 404 to move downward, and the mounting plate 404 drives the universal wheel 405 to move downward, thereby facilitating the adjustment of the height of different corners of the mounting frame 1, avoiding the shaking of the lifting equipment due to the uneven ground, and improving the stability.

[0039] Specifically, Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the guide structure 5 includes two brackets 501 and a connecting rod 502 fixedly connected between the two brackets 501, the front end of the mounting frame 1 is fixedly connected to the bracket 501, a slider 503 is provided on the connecting rod 502, the bottom end of the slider 503 is rotatably connected to three rollers 504, the three rollers 504 are all rollingly connected to the connecting rod 502, the top of the slider 503 is rotatably connected to a second guide wheel 505, the top of the slider 503 is slidably connected to a baffle 506, the end of the baffle 506 is fixedly connected to the outer wall of the slider 503 with a tension spring 507, the three rollers 504 form a triangular structure, and the baffle 506 is provided with an inclined surface; before the wire rope is connected to the second boom 203, it needs to bypass the second guide wheel 505 first, and the baffle can be pressed downward with the wire rope. The second guide wheel 505 is provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504. The plurality of rollers 504 are provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504. The plurality of rollers 504 are provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504.

[0040] Specifically, Figure 1 , Figure 5 , Figure 8 and Fig. 9 As shown, the lifting structure 6 includes a placement frame 601 and two hydraulic rods 602 respectively fixed at both ends of the placement frame 601, the inner wall of the mounting frame 1 is slidably connected with the placement frame 601, the end of the hydraulic rod 602 is fixedly connected with a connecting plate 603, the connecting plate 603 is slidably connected to the inner wall of the mounting frame 1, and a second spring 604 is fixedly connected between the bottom surface of the connecting plate 603 and the inner wall of the mounting frame 1, the placement frame 601 is in a "U" shape, and two symmetrical motors 7 are fixedly connected to the mounting frame 1, and a pay-off wheel 8 is fixedly connected between the output shafts of the two motors 7, and the pay-off wheel 8 is rotatably connected to the mounting frame 1; when the assembly of the hoisting equipment is completed, it is necessary to add counterweights to the equipment to prevent the equipment from tipping over due to the heavy weight of the doors and windows during the hoisting process, and it is only necessary to place counterweight objects one by one on the placement frame 601, and then the placement frame 601 moves downward along the inner wall of the mounting frame 1 under the action of gravity. The mounting frame 601 slides and drives the hydraulic rod 602 to move downward. Since the end of the hydraulic rod 602 is fixedly connected to the connecting plate 603, the hydraulic rod 602 drives the connecting plate 603 to slide downward and compress the second spring 604 until the bottom surface of the mounting frame 601 contacts the ground, thereby effectively placing the equipment sideways. At the same time, since the bottom surface of the mounting frame 601 directly contacts the ground after the counterweight is added, the equipment is effectively prevented from moving through the universal wheel 405 under the action of external force during the lifting process. When the equipment needs to be rotated during the lifting process, the telescopic ends of the two hydraulic rods 602 retract inwardly, and the ends contact the second spring 604 and the inside of the mounting frame 1 through the connecting plate 603, thereby the telescopic ends of the hydraulic rod 602 drive the mounting frame 601 to move upward along the inner wall of the mounting frame 1 for a distance until the bottom surface of the mounting frame 601 no longer contacts the ground. At this time, the angle of the equipment can be adjusted through the universal wheel 405, which is easy to operate and has strong flexibility.

[0041] When the present invention is in use, the hoisting equipment is first assembled. Since a part of the wall will be reserved when the doors and windows are installed, and then the doors and windows are buried in the reserved wall, it is necessary to adjust the height of the first hanging arm 202 when assembling the hoisting equipment, first move the mounting frame 1 to a suitable position, and then connect the first hanging arm 202 to the mounting seat 201 at the bottom end of the mounting frame 1 through the connecting shaft, and then insert the second hanging arm 203 into the internal cavity of the first hanging arm 202, and adjust the total length of the first hanging arm 202 and the second hanging arm 203 to a suitable size, and then fix the first hanging arm 202 and the second hanging arm 203 through the latch, and then squeeze the limiting rods 207 on both sides of the slide 206 inward, and then the two limiting rods 207 slide toward the inside of the second hanging arm 203 and compress the first spring 209, and at the same time, the limiting rod 207 drives the limiting block 208 at the end to disengage from the limiting groove 205 inside the second hanging arm 203, and then move the slide 206 back and forth. , so that the limit rod 207 on the slide 206 slides forward and backward along the slide groove 204, at this time, the slide 206 drives the support frame 210 fixed at the bottom to move forward and backward, and the support frame 210 drives the first rotating wheel 211 to roll on the ground. When the slide 206 moves to the appropriate position, the two limit rods 207 are released, and then the limit rod 207 and the limit block 208 at its end are driven to move toward the outside of the second hanging arm 203 under the reset action of the first spring 209, until the limit block 208 is engaged with another limit groove 205 inside the second hanging arm 203, thereby effectively limiting the slide 206, avoiding relative sliding between the slide 206 and the second hanging arm 203 during the process of hanging doors and windows, thereby improving stability. At this time, the inclination angle between the first hanging arm 202 and the mounting frame 1 is adjusted by changing the distance between the support frame 210 and the end of the second hanging arm 203, so as to adapt to cement walls of different heights at the edge of the floor, and the flexibility is strong;

[0042] To avoid the problem of damage due to local force when the door and window are pulled to the end of the second hanging arm 203, it is only necessary to rotate the knob 304 at the end of the first slide bar 301, and then pull the two second slide bars 302 outward, and then control the distance of pulling the second slide bars 302 outward according to the size of the door and window. When the two second slide bars 302 are pulled outward to a suitable length, the knob 304 is tightened in the opposite direction to make the bottom of the knob 304 engage with the limiting hole 303 at the top of the second slide bar 302, thereby completing the fixation of the second slide bar 302 with strong stability. Then, when the door and window are lifted upward, the two motors 7 on the mounting frame 1 drive the The pay-off wheel 8 rotates, and then the pay-off wheel 8 recovers the wire rope, the first guide wheel 308 at the front end of the second suspension arm 203 rotates through the second rotating shaft 307, and the wire rope is turned through the first guide wheel 308. When the wire rope pulls the door and window to the third rotating wheel 309 at both ends of the second rotating shaft 307, the bottom surface of the door and window simultaneously abuts against the second rotating wheel 306 at the end of the second sliding rod 302, and the second rotating wheel 306 rotates through the first rotating shaft 305, thereby reducing the friction between the second rotating wheel 306 and the door and window, making it easy to quickly pull the door and window into the room, with simple operation and strong flexibility, and can effectively avoid damage to the door and window;

[0043] When the ground where the hoisting equipment is placed is uneven, the screw rod 402 can be rotated by simply rotating the handle 403. Since the screw rod 402 is threadedly connected to the mounting block 401, the screw rod 402 drives the mounting plate 404 to move downward, and the mounting plate 404 drives the universal wheel 405 to move downward, so that the height of different corners of the mounting frame 1 can be adjusted, and the hoisting equipment can be prevented from shaking due to the uneven ground, thereby improving stability.

[0044] The second guide wheel 505 is provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504. The plurality of rollers 504 are provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504. The plurality of rollers 504 are provided with a plurality of rollers 504, and the plurality of rollers 504 are provided with a plurality of rollers 504.

[0045] After the assembly of the lifting equipment is completed, it is necessary to add counterweights to the equipment to prevent the equipment from tipping over due to the heavy weight of the doors and windows during the lifting process. It is only necessary to place counterweights one by one on the placement rack 601, and then the placement rack 601 slides downward along the inner wall of the mounting rack 1 under the action of gravity, and the placement rack 601 drives the hydraulic rod 602 to move downward. Since the end of the hydraulic rod 602 is fixedly connected to the connecting plate 603, the hydraulic rod 602 drives the connecting plate 603 to slide downward and compress the second spring 604 until the bottom surface of the placement rack 601 contacts the ground, thereby effectively preventing the equipment from tipping over. At the same time, due to After adding the counterweight, the bottom surface of the placement frame 601 directly contacts the ground, thereby effectively preventing the equipment from moving through the universal wheel 405 under the action of external force during the lifting process. When the equipment needs to be rotated during the lifting process, the telescopic ends of the two hydraulic rods 602 retract inward, and the ends contact the second spring 604 and the inside of the mounting frame 1 through the connecting plate 603, and then the telescopic ends of the hydraulic rods 602 drive the placement frame 601 to move upward along the inner wall of the mounting frame 1 for a distance until the bottom surface of the placement frame 601 no longer contacts the ground. At this time, the angle of the equipment can be adjusted through the universal wheel 405, which is easy to operate and has strong flexibility.
