Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to an attached construction lifting platform and its lifting method. Background Technology

[0002] Lifting platforms can be customized to meet specific user requirements. They are applicable to high-altitude operations and maintenance in factories, automated warehouses, parking lots, municipal works, docks, construction, decoration, logistics, power, transportation, petroleum, chemical, hotels, stadiums, mines, and other enterprises.

[0003] Existing lifting platforms are generally large in size and cannot be moved easily. At the same time, a lot of manpower is needed in the process of erecting scaffolding to reduce the completion cost. Traditional scaffolding erection requires a lot of materials and labor, which increases construction costs to a certain extent and delays the construction progress. Summary of the Invention

[0004] The purpose of this invention is to provide an attached construction lifting platform and lifting method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an attached construction lifting platform, comprising a main body, with two hollow blocks fixedly connected to the left and right outer walls of the main body, a toothed plate bolted to the side of the main body near the hollow blocks, and two C-shaped plates bolted to the side of the main body near the toothed plates, the two C-shaped plates being symmetrically distributed around the toothed plates, two L-plates fixedly connected to the side of the main body near the toothed plates, and a plurality of circular shafts fixedly connected inside the C-shaped plates, the plurality of circular shafts being arranged at equal intervals, and further comprising;

[0007] The connecting mechanism includes a base frame that is slidably connected to the outer surface of the main body. Two limiting frames are fixedly connected inside the base frame on the side closest to the hollow block. The two limiting frames are symmetrically distributed around the toothed plate. Two vertical plates are fixedly connected to the bottom outer wall of the base frame. The two vertical plates are symmetrically distributed around the main body. A fixing plate is fixedly connected to the inner wall of the base frame on the side closest to the main body.

[0008] The auxiliary mechanism includes two limit blocks inserted inside the limit frame. The limit blocks are connected to the limit frame by bolts. A lifting platform is fixedly connected to the top of the four limit blocks. Two railings are fixedly connected to the side of the lifting platform away from the limit blocks.

[0009] Furthermore, the two fences are symmetrically distributed around the center line of the lifting platform. The side walls of the fences are rotatably connected with latches. An electrical control box is fixedly connected to the side of the lifting platform closer to the main body. Two rollers are rotatably connected to the side of the electrical control box away from the latches. The two rollers are symmetrically arranged and contact the side wall of the L-plate. Two limit rings are fixedly connected to the side of the lifting platform away from the rollers.

[0010] Furthermore, the basic frame is equipped with a transmission mechanism, which includes two take-up shafts rotatably connected to the side of the vertical plate near the fixed plate. The side of the take-up shaft away from the fixed plate passes through the side wall of the vertical plate and extends to the outside. The outer surfaces of the two take-up shafts located at the bottom of the fixed plate are fitted with belts. The side walls of the belts are equipped with power motors. The top of the power motors is fixedly connected to the bottom side wall of the fixed plate. The outer surface of the output end of the power motors is fitted and connected to the middle of the belt.

[0011] Furthermore, the output end of the power motor passes through the side wall of the vertical plate and extends to the outside. The outer surface of the extended end of the power motor is fixedly connected with teeth, which mesh with the toothed plate. The extended end of the winding shaft is fixedly connected with a hanging chain. The end of the hanging chain away from the winding shaft passes through the side wall of the hollow block and extends to the top of the lifting platform. The end of the hanging chain away from the winding shaft is fixedly connected with a hanging ring, which is slidably connected inside the limiting ring.

[0012] Furthermore, the auxiliary mechanism is provided with a stabilizing mechanism on its side wall. The stabilizing mechanism includes four connecting plates bolted to the side of the lifting platform near the roller. The four connecting plates are arranged symmetrically in pairs. The two pairs of connecting plates are symmetrically distributed with the center line of the lifting platform as the center. A square block is fixedly connected to the side of the connecting plate away from the lifting platform. A rectangular frame is opened on the side of the connecting plate near the square block. A square frame is fixedly connected to the side of the square block away from the connecting plate.

[0013] Furthermore, the side of the square frame away from the square block is open, extending through to the bottom outer wall of the square frame. A semicircular plate is slidably connected to the inner wall of the square frame near the square block. The semicircular plate extends through to the side wall of the square frame and to the outer wall, with the extended end of the semicircular plate inclined and in contact with the sliding plate. A return spring is fixedly connected between the semicircular plate and the square frame. An obtuse-angled plate is rotatably connected inside the square frame, and an inclined plate is fixedly connected to the outer surface of the obtuse-angled plate, with the inclined plate in contact with the circular shaft.

[0014] Furthermore, a reinforcing mechanism is provided at the top of the square frame. The reinforcing mechanism includes two connecting ears fixedly connected to the top of the square frame. A rotating shaft is rotatably connected between the two connecting ears. A shaped block is fixedly connected to the end of the rotating shaft away from the connecting ears. The side of the shaped block away from the rotating shaft is open. A movable shaft is rotatably connected to the side of the rotating shaft near the connecting plate.

[0015] Furthermore, a movable shaft is rotatably connected to the side of the movable shaft away from the rotating shaft. The side of the movable shaft away from the movable shaft extends through to the bottom outer wall of the square block and extends to the outer wall. A rectangular plate is fixedly connected to the outer surface of the movable shaft between the connecting plate and the movable shaft. A tension spring is fixedly connected between the rectangular plate and the connecting plate. A sliding plate is fixedly connected to the extended end of the movable shaft. The side of the sliding plate near the rectangular frame is inserted into the inside of the rectangular frame. The rectangular frame and the sliding plate are slidably connected.

[0016] Furthermore, an attached construction lifting platform, and a lifting method for the attached construction lifting platform, includes the following steps:

[0017] S1: First, pass the chain through the hollow block and assemble the hollow block onto the main body. Then, attach the base frame to the outer surface of the main body and assemble the main body to the required height.

[0018] S2: Then, the toothed plate and C-shaped plate are installed on both sides of the main body by bolts, so that the toothed plate meshes with the teeth on the output end of the power motor;

[0019] S3: Then install the rollers on the lifting platform and let them slide inside the L-plate;

[0020] S4: Then start the power motor. When the power motor is working, it will drive this connecting mechanism and auxiliary mechanism to rise and fall on the surface of the main body through the meshing of the teeth and the tooth plate.

[0021] The present invention has the following beneficial effects:

[0022] 1. This invention first involves passing a lifting chain through a hollow block and assembling the hollow block onto the main body. Then, a base frame is fitted onto the outer surface of the main body, and the main body is assembled to the required height. Next, a toothed plate and a C-shaped plate are bolted to both sides of the main body, allowing the toothed plate to mesh with the teeth on the output end of the power motor. Rollers then slide inside the L-plate. The power motor is then started. During operation, the meshing of the teeth with the toothed plate drives the connecting mechanism and auxiliary mechanism to rise and fall on the surface of the main body. Simultaneously, the power motor drives a winding shaft via a belt. This rotation of the winding shaft, through the lifting chain and hanging ring, raises the lifting platform. Since the limiting block at the bottom of the lifting platform is bolted to the base frame, when the lifting chain pulls the lifting platform, it also lifts the connecting mechanism, enhancing the lifting operation generated by the meshing of the power motor output end and the toothed plate. The components of this device can be directly spliced ​​and installed on-site, typically requiring only one hoisting operation, saving manpower, improving construction efficiency, and reducing the dangers of high-altitude erection.

[0023] 2. This invention allows for the splicing and installation of multiple lifting platforms on a basic frame during assembly. The lifting platforms are then joined together via bayonets. After assembly, the power motor is activated. During operation, the power motor drives the device to lift and lower through the meshing of the teeth at its output end with the tooth plate, thus completing the work operation or transporting goods. When two lifting platforms are spliced ​​together, they can also be connected for work on a large area. It has excellent effects in decoration, exterior wall bricklaying, and goods transportation.

[0024] 3. In this invention, during the upward movement of the device, the rising lifting platform drives the stabilizing mechanism to rise synchronously. As the stabilizing mechanism rises, because the upward speed of the device is relatively slow, the circular shaft continuously presses against the inclined plate. This pressure causes the obtuse-angled plate to rotate, which in turn presses against the semicircular plate. During this slow upward movement, the semicircular plate does not significantly displace the sliding plate. When the inclined plate disengages from the circular shaft, the return spring on the semicircular plate pushes against the obtuse-angled plate to reset. When the device slides downwards during the upward movement, it will slide down at a relatively fast speed. The inclined plate will squeeze the circular shaft, and because the downward speed is too fast, the obtuse-angled plate cannot reset in time. At this time, the bottom end of the obtuse-angled plate will be stuck on the surface of the circular shaft, which will play a role in preventing it from falling. At the same time, when the obtuse-angled plate rotates and is stuck on the circular shaft, the top end of the obtuse-angled plate will squeeze the semicircular plate. After being squeezed, the semicircular plate will push against the inclined block at the extension end of the semicircular plate to squeeze the sliding plate. After being squeezed, the sliding plate will slide upward inside the rectangular frame. During the upward movement of the sliding plate, it will push against the movable shaft through the moving shaft to make the movable shaft rise synchronously. When the movable shaft rises, it will push against the rotating shaft to rotate around the connecting ear, so that the opening on the irregular block is stuck on the circular shaft, ensuring the stability of this device and improving the stability of this device.

[0025] 4. This invention allows for the simultaneous lifting of multiple platforms during operation. The device primarily consists of a connecting mechanism, an auxiliary mechanism, and a transmission mechanism, which are crucial for ensuring the stable lifting of the platform. The C-shaped and L-shaped plates on both sides of the main body serve to fix the auxiliary mechanism for platform lifting, enabling the device to lift two platforms from both sides in one direction during operation. Before the building structure is topped out, facade construction can be carried out on the ground floor, adjusting the work direction to work from bottom to top. Compared to traditional suspended platforms, this device allows for facade construction and adjustment of the work direction before the building is topped out, improving construction efficiency and reducing work time.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-8 As shown, the present invention is an attached construction lifting platform, comprising a main body 1. Two hollow blocks 101 are fixedly connected to the left and right outer walls of the main body 1. A toothed plate 102 is bolted to the side of the main body 1 near the hollow blocks 101. Two C-shaped plates 103 are bolted to the side of the main body 1 near the toothed plate 102. The two C-shaped plates 103 are symmetrically distributed with the toothed plate 102 as the center. Two L-plates 104 are fixedly connected to the side of the main body 1 near the toothed plate 102. A plurality of circular shafts 105 are fixedly connected inside the C-shaped plates 103. The plurality of circular shafts 105 are arranged at equal intervals.

[0041] The connecting mechanism 2 includes a base frame 201 slidably connected to the outer surface of the main body 1. Two limiting frames 202 are fixedly connected inside the base frame 201 on the side near the hollow block 101. The two limiting frames 202 are symmetrically distributed around the toothed plate 102. Two vertical plates 203 are fixedly connected to the bottom outer wall of the base frame 201. The two vertical plates 203 are symmetrically distributed around the main body 1. A fixing plate 204 is fixedly connected to the inner wall of the base frame 201 on the side near the main body 1.

[0042] The auxiliary mechanism 3 includes two limiting blocks 307 inserted into the limiting frame 202. The limiting blocks 307 are connected to the limiting frame 202 by bolts. The top of the four limiting blocks 307 is fixedly connected to a lifting platform 301. Two railings 302 are fixedly connected to the side of the lifting platform 301 away from the limiting blocks 307. When this device is assembled, the lifting platforms 301 on multiple base frames 201 can be spliced ​​and installed. Then, the lifting platforms 301 are spliced ​​together through the bayonet 303. After the splicing is completed, the power motor 401 is started. When the power motor 401 is working, it will drive the device to lift and lower through the meshing of the teeth at the output end with the tooth plate 102.

[0043] Two fences 302 are symmetrically distributed around the center line of the lifting platform 301. The side walls of the fences 302 are rotatably connected to the bayonet 303. The side of the lifting platform 301 closest to the main body 1 is fixedly connected to the electrical control box 304. The side of the electrical control box 304 away from the bayonet 303 is rotatably connected to two rollers 305. The two rollers 305 are symmetrically arranged and contact the side wall of the L plate 104. The side of the lifting platform 301 away from the rollers 305 is fixedly connected to two limit rings 306. The toothed plate 102 and the C-shaped plate 103 are installed on both sides of the main body 1 by bolts, so that the toothed plate 102 meshes with the teeth on the output end of the power motor 401.

[0044] The basic frame 201 is internally equipped with a transmission mechanism 4. The transmission mechanism 4 includes two take-up shafts 403 rotatably connected to the side of the vertical plate 203 near the fixed plate 204. The side of the take-up shafts 403 away from the fixed plate 204 extends through the side wall of the vertical plate 203 and outwards. The outer surfaces of the two take-up shafts 403 located at the bottom of the fixed plate 204 are fitted with belts 402. A power motor 401 is installed on the side wall of the belts 402. The top of the power motor 401 is fixedly connected to the bottom side wall of the fixed plate 204. The outer surface of the output end is sleeved and connected to the middle of the belt 402. Then, the roller 305 slides inside the L plate 104. Then, the power motor 401 is started. When the power motor 401 is working, it will drive the connecting mechanism 2 and the auxiliary mechanism 3 to rise and fall on the surface of the main body 1 through the meshing of the teeth with the tooth plate 102. When the power motor 401 is working, it will also drive the winding shaft 403 to rotate through the belt 402. When the winding shaft 403 rotates, it will drive the lifting platform 301 to rise through the hanging chain 404 and the hanging ring 405.

[0045] The output end of the power motor 401 passes through the side wall of the vertical plate 203 and extends to the outside. The outer surface of the extended end of the power motor 401 is fixedly connected with teeth, which mesh with the toothed plate 102. The extended end of the take-up shaft 403 is fixedly connected with a hanging chain 404. The end of the hanging chain 404 away from the take-up shaft 403 passes through the side wall of the hollow block 101 and extends to the top of the lifting platform 301. The end of the hanging chain 404 away from the take-up shaft 403 is fixedly connected with a hanging ring 405. The hanging ring 405 is slidably connected inside the limiting ring 306. First, the hanging chain 404 is passed through the hollow block 101 and the hollow block 101 is assembled on the main body 1. Then, the base frame 201 is sleeved on the outer surface of the main body 1.

[0046] The auxiliary mechanism 3 has a stabilizing mechanism 5 on its side wall. The stabilizing mechanism 5 includes four connecting plates 501 bolted to the side of the lifting platform 301 near the roller 305. The four connecting plates 501 are arranged symmetrically in pairs. The two pairs of connecting plates 501 are symmetrically distributed with the center line of the lifting platform 301 as the center. A square block 502 is fixedly connected to the side of the connecting plate 501 away from the lifting platform 301. A rectangular frame 503 is opened on the side of the connecting plate 501 near the square block 502. A square frame 504 is fixedly connected to the side of the square block 502 away from the connecting plate 501. The rising lifting platform 301 will drive the stabilizing mechanism 5 to rise synchronously. When the stabilizing mechanism 5 rises, because the rising speed of this device is relatively slow, the circular shaft 105 will continuously squeeze the inclined plate 507 when the device rises. After the inclined plate 507 is squeezed, it will drive the obtuse angle plate 506 to rotate. After the obtuse angle plate 506 rotates, it will squeeze the semicircular plate 505.

[0047] The square frame 504 has an opening on the side away from the square block 502, extending to the bottom outer wall of the square frame 504. A semicircular plate 505 is slidably connected to the inner wall of the square frame 504 near the square block 502. The semicircular plate 505 extends through the side wall of the square frame 504 and to the outer wall, with the extended end of the semicircular plate 505 inclined. The extended end of the semicircular plate 505 contacts the sliding plate 607. A return spring is fixedly connected between the semicircular plate 505 and the square frame 504. An obtuse angle plate 506 is rotatably connected inside the square frame 504. An inclined plate 507 is fixedly connected to the surface. The inclined plate 507 is in contact with the circular shaft 105. At this time, when the device is slowly rising and falling, the semicircular plate 505 will not push against the sliding plate 607 and cause a large displacement. Afterwards, when the inclined plate 507 is separated from the circular shaft 105, the return spring on the semicircular plate 505 will push against the obtuse angle plate 506 to reset. When the device slides down during the rising process, the device will slide down at a relatively fast speed. When the device slides down quickly, the inclined plate 507 will squeeze the circular shaft 105, and because the speed of the slide is too fast, the obtuse angle plate 506 will not have time to reset.

[0048] A reinforcing mechanism 6 is provided at the top of the square frame 504. The reinforcing mechanism 6 includes two connecting ears 601 fixedly connected to the top of the square frame 504. A rotating shaft 602 is rotatably connected between the two connecting ears 601. A shaped block 603 is fixedly connected to the end of the rotating shaft 602 away from the connecting ears 601. The side of the shaped block 603 away from the rotating shaft 602 is open. A movable shaft 604 is rotatably connected to the side of the rotating shaft 602 near the connecting plate 501. At this time, the bottom end of the obtuse angle plate 506 will be stuck on the surface of the round shaft 105 to prevent it from falling. At the same time, when the obtuse angle plate 506 rotates and is stuck on the round shaft 105, the top end of the obtuse angle plate 506 will press against the semicircular plate 505. After being pressed, the semicircular plate 505 will press against the inclined block at the extension end of the semicircular plate 505 to press the sliding plate 607. After being pressed, the sliding plate 607 will slide upward inside the rectangular frame 503.

[0049] A movable shaft 605 is rotatably connected to the side of the movable shaft 604 away from the rotating shaft 602. The side of the movable shaft 605 away from the movable shaft 604 extends through to the bottom outer wall of the square block 502 and extends to the outer wall. A rectangular plate 606 is fixedly connected to the outer surface of the movable shaft 605 between the connecting plate 501 and the movable shaft 604. A tension spring is fixedly connected between the rectangular plate 606 and the connecting plate 501. A sliding plate 607 is fixedly connected to the extended end of the movable shaft 605. The side of the sliding plate 607 near the rectangular frame 503 is inserted into the inside of the rectangular frame 503. The rectangular frame 503 and the sliding plate 607 are slidably connected. During the upward movement of the sliding plate 607, the movable shaft 604 is pushed by the movable shaft 605, causing the movable shaft 604 to rise synchronously. When the movable shaft 604 rises, it pushes the rotating shaft 602 to rotate around the connecting ear 601, so that the opening on the irregular block 603 is locked on the round shaft 105, ensuring the stability of the device and improving its stability.

[0050] A lifting method for an attached construction lifting platform includes the following steps:

[0051] S1: First, pass the hanging chain 404 through the hollow block 101 and assemble the hollow block 101 onto the main body 1. Then, attach the base frame 201 to the outer surface of the main body 1 and assemble the main body 1 to the required height.

[0052] S2: Then, the toothed plate 102 and the C-shaped plate 103 are installed on both sides of the main body 1 by bolts, so that the toothed plate 102 meshes with the teeth on the output end of the power motor 401;

[0053] S3: Then install the roller 305 on the lifting platform 301 and let it slide inside the L plate 104;

[0054] S4: Then start the power motor 401. When the power motor 401 is working, it will drive the connecting mechanism 2 and the auxiliary mechanism 3 to rise and fall on the surface of the main body 1 through the meshing of the teeth with the tooth plate 102.

[0055] In use, first, the chain 404 is passed through the hollow block 101, and the hollow block 101 is assembled onto the main body 1. Then, the base frame 201 is fitted onto the outer surface of the main body 1, and the main body 1 is assembled to the required height. Then, the toothed plate 102 and the C-shaped plate 103 are installed on both sides of the main body 1 with bolts, so that the toothed plate 102 meshes with the teeth on the output end of the power motor 401. Then, the roller 305 slides inside the L-plate 104. Then, the power motor 401 is started. When the power motor 401 is working, it will drive the connecting mechanism 2 and the auxiliary mechanism 3 to rise and fall on the surface of the main body 1 through the meshing of the teeth with the toothed plate 102. The belt 402 will also drive the winding shaft 403 to rotate. When the winding shaft 403 rotates, it will drive the lifting platform 301 to rise through the chain 404 and the hanging ring 405. Since the limit block 307 at the bottom of the lifting platform 301 is connected to the base frame 201 by bolts, when the chain 404 pulls the lifting platform 301 to move, it will also carry the connecting mechanism 2 to rise. This can enhance the lifting work generated by the meshing of the output end of the power motor 401 and the toothed plate 102. The components of this device can be directly spliced ​​and installed on the construction site. Generally, the installation can be completed in one hoisting, saving manpower, improving construction efficiency, and reducing the danger of high-altitude erection.

[0056] When this device is assembled, multiple lifting platforms 301 on the base frame 201 can be spliced ​​and installed. Then, the lifting platforms 301 are spliced ​​together through the bayonet 303. After the splicing is completed, the power motor 401 is started. When the power motor 401 is working, it will drive the device to lift and lower through the meshing of the teeth at the output end with the tooth plate 102, so as to complete the operation or transport goods. When two lifting platforms 301 are spliced ​​together, they can also be connected for a large area. It has good effects in decoration, exterior wall bricklaying and goods transportation.

[0057] During the ascent of this device, the rising platform 301 drives the stabilizing mechanism 5 to rise synchronously. Because the ascent speed of this device is relatively slow, the circular shaft 105 continuously presses against the inclined plate 507 during ascent. This pressure causes the obtuse-angle plate 506 to rotate, which in turn presses against the semicircular plate 505. During this slow ascent and descent, the semicircular plate 505 does not significantly displace the sliding plate 607. When the inclined plate 507 disengages from the circular shaft 105, the return spring on the semicircular plate 505 returns to its original position against the obtuse-angle plate 506. If the device slides downwards during ascent, it will slide at a relatively fast speed. During this rapid slide, the inclined plate 507 will press against the circular shaft 105. Furthermore, due to the excessively rapid descent, the obtuse angle plate 506 cannot reset in time. At this point, the bottom end of the obtuse angle plate 506 will be stuck on the surface of the round shaft 105, serving as a fall prevention measure. Simultaneously, when the obtuse angle plate 506 rotates and is stuck on the round shaft 105, the top end of the obtuse angle plate 506 will press against the semicircular plate 505. After being pressed, the semicircular plate 505 will press against the inclined block at the extended end of the semicircular plate 505, thus pressing against the sliding plate 607. After being pressed, the sliding plate 607 will slide upward inside the rectangular frame 503. During the upward movement of the sliding plate 607, the moving shaft 605 will push against the movable shaft 604, causing the movable shaft 604 to rise synchronously. When the movable shaft 604 rises, it will push against the rotating shaft 602 to rotate around the connecting ear 601, causing the opening on the irregular block 603 to be stuck on the round shaft 105, ensuring the stability of the device and improving its stability.

[0058] This device can simultaneously lift multiple platforms during operation. It mainly consists of a connecting mechanism 2, an auxiliary mechanism 3, and a transmission mechanism 4, which are crucial for ensuring the stable lifting of the platform. The C-shaped plates 103 and L-shaped plates 104 on both sides of the main body 1 serve to fix the auxiliary mechanism 3 for platform lifting, allowing the device to lift two platforms from both sides in one direction during operation. Before the building structure is topped out, facade construction can be carried out on the ground floor, adjusting the work direction and working from bottom to top. Compared to traditional suspended platforms, this device allows for facade construction and adjusting the work direction before the building is topped out, improving construction efficiency and reducing working time.
