Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically a multi-functional lifting platform for foundation construction in underwater building construction. Background Technology

[0002] Underwater construction, as the name suggests, refers to construction projects carried out in aquatic environments such as rivers, lakes, and oceans. It integrates multiple disciplines such as civil engineering, marine engineering, and diving technology, and is a special construction field with extremely high technical requirements, high risks, and high costs.

[0003] Elevating platforms are one of the essential pieces of equipment in underwater construction. The core function of elevating platforms in the construction process can be summarized as: providing a stable, safe and precisely controllable variable-depth working base for personnel, equipment and materials.

[0004] At that time, during the application of the lifting platform, the basket moves down to the bottom of the water below the ground. During the up and down movement of the basket, when the basket moves to the ground, it is in a suspended state. At this time, the basket is supported by the steel wire rope in the hoisting structure. The support received by the basket is limited. When personnel enter or exit or goods are moved into the basket, the basket is subjected to force and swaying, which poses a significant safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-functional lifting platform for foundation construction in underwater building construction, so as to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional lifting platform for foundation construction in underwater building construction, comprising a support structure, wherein the support structure is driven by a hoisting structure, the hoisting structure comprising two fixed frames, a hydraulic cylinder, a limiting frame, and two positioning plates, wherein a hoisting assembly is installed at the bottom of each of the two fixed frames, a basket structure is installed between the two hoisting assemblies, the piston end of the hydraulic cylinder is fixedly connected to the limiting frame, and two locking assemblies are provided at the top of the limiting frame, the locking assemblies driving the two positioning plates, one of which is a fixed frame. A mounting groove is provided on one side of the positioning plate near the positioning component. A pressure sensor is installed inside the mounting groove. The suspended basket structure includes an outer frame. Two material trays are slidably installed inside the outer frame. Two positioning plates are fixedly installed on the top front and top rear sides of the outer frame, respectively. The two sides of the outer frame are limited by the cooperation of the two positioning plates and four positioning plates, which limits the forward and backward movement of the outer frame and provides a suspension positioning function for the suspended basket structure. This further increases the stability of the outer frame during suspension and avoids shaking of the outer frame during personnel entering and exiting the inner part of the outer frame. A long groove is provided on one side of the positioning plate.

[0007] Preferably, the support structure includes two vertical beams, two winches, two guide rails, two trolleys, and multiple bolts.

[0010] Preferably, the hoisting assembly includes a dual-shaft output geared motor fixedly connected to the bottom of a fixed frame and two drive shafts fixedly connected to the two output ends of the dual-shaft output geared motor. A winding frame is fixedly sleeved on the outside of the drive shaft. A second steel wire rope is fixedly installed inside the winding frame. The bottom end of the second steel wire rope is fixedly connected to the outer frame. Two second fixed frames are rotatably sleeved on the outside of the drive shaft. The top ends of the second fixed frames are fixedly connected to the first fixed frame. A brake is sleeved on the outside of the drive shaft. After the brake is activated, it brakes the drive shaft, stopping and limiting its rotation. The rotation of the winding frame is limited, and the top of the suspended basket structure is blocked and limited by the limiting frame, thus limiting the vertical movement of the suspended basket structure. The brake is fixedly connected to the first fixed frame.

[0011] Preferably, the positioning assembly includes a pneumatic cylinder mounted on the top of the limiting frame, a fixed frame four fixedly connected to the piston end of the pneumatic cylinder, a multi-axis gearbox fixedly connected to the top of the fixed frame four, and a drive motor fixedly connected to the top of the multi-axis gearbox. Gear one is fixedly connected to the outer side of both output ends of the multi-axis gearbox, controlling the drive motor to output rotational force. The rotational force is applied to the two gear ones under the action of the fixed frame four, and the gear ones rotate. Two rotating shafts are rotatably mounted on the fixed frame four, and the two rotating shafts are fixedly connected to two positioning plates one respectively.

[0012] Preferably, the output end of the drive motor is fixedly connected to the input end of the multi-axis gearbox.

[0015] Preferably, the material tray has limiting grooves on both sides, and limiting guide rails are provided inside the limiting grooves. The two limiting guide rails on both sides are fixedly connected to the outer frame. A partition plate is fixedly connected between the two limiting guide rails in the middle and the outer frame. The bottom of the material tray has multiple reserved cavities, and multiple rollers are provided inside the reserved cavities. The multiple rollers reduce the movement resistance of the material tray. The rollers are rotatably connected to the material tray. The material tray supported by the multiple rollers moves away from the inside of the outer frame, so that part of the material tray moves to the top of the construction platform.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When this application is used, the pneumatic cylinder stops working after the pressure value detected by the two pressure sensors reaches the preset value; at this time, the outer frame is limited by the cooperation of two positioning plates and four positioning plates on both sides, and the forward and backward movement of the outer frame is limited, providing a suspension positioning function for the suspended basket structure, further increasing the stability of the outer frame suspension, avoiding the shaking of the outer frame during the process of personnel entering and leaving the inner part of the outer frame, ensuring the safety of personnel, and providing support and positioning for personnel to move low-weight goods and tools into the suspended basket structure.

[0017] 2. When this application is used, the material tray can move out of the inner frame and away from the outer frame when the mesh is opened. Multiple reserved cavities at the bottom of the material tray are equipped with multiple rollers. The rollers are rotatably connected to the material tray. When the bottom of the inner cavity of the outer frame is aligned with the construction platform, the material tray can be pulled. The material tray, supported by multiple rollers, moves away from the inner frame and partially moves to the top of the construction platform. At this time, the material tray is well supported by the construction platform and is less obstructed on the outside of the outer frame, so that goods can be conveniently and quickly stacked on top of the material tray. After the goods on top of the material tray are loaded and unloaded, the material tray is pushed back into the outer frame to ensure that the loading and unloading of goods in the basket structure is quick and convenient.

[0018] 3. When this application is used, one winch works to wind up the wire rope, and another winch works to unwind the wire rope, so that the trolley moves left and right. The two fixed frames in the winch structure are fixedly connected to the two trolleys respectively. The winch structure and the suspended basket structure installed on the two trolleys move left and right, thus widening the effective working range of the suspended basket structure.

[0021] 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.

[0022] Example: Figures 1-13 As shown, the present invention provides a technical solution for a multi-functional lifting platform for foundation construction in underwater building construction, including a support structure 1, a winch structure 2 driven by the support structure 1, the winch structure 2 including two fixed frames 21, a hydraulic cylinder 29, a limiting frame 211 and two positioning plates 224, the bottom of the two fixed frames 21 are equipped with winch components, and a basket structure 3 is installed between the two winch components. The piston end of the hydraulic cylinder 29 is fixedly connected to the limiting frame 211, and the top of the limiting frame 211 is provided with two locking components, which drive two positioning plates 221. One of the positioning plates 221 has an installation groove 223 on the side near the locking component, and a pressure sensor 222 is installed inside the installation groove 223. The basket structure 3 includes an outer frame 31, and two material trays 37 are slidably installed inside the outer frame 31. The two positioning plates 224 are respectively fixedly installed on the top front side and the top rear side of the outer frame 31, and a long groove 225 is opened on one side of the positioning plate 224.

[0023] The multi-functional lifting platform consists of a support structure 1, a hoisting structure 2, and a suspended platform structure 3. The installation of human-machine interface equipment to control the operation of the multi-functional lifting platform is existing technology and will not be described in detail here.

[0024] The application methods of the multi-functional lifting platform are as follows: Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown; A winch 12 is fixedly installed on each of the two vertical beams 11. A trolley 110 is fixedly connected to one end of the wire rope 13 in the winch 12. A connecting shaft 111 is fixedly connected between the two trolleys 110. The two trolleys 110 are integrated and move synchronously. An installation sleeve 17 is fixedly installed on the outside of the left vertical beam 11.

[0025] Prepare multiple guide rails 15 according to construction needs, fix and install mounting sleeve 14 on the outer right side of the guide rail 15, open two threaded holes 18 on the top of mounting sleeve 14, and open two threaded holes 16 on the top of the right vertical beam 11 and the top left side of the guide rail 15 to complete the construction and fixation of the support structure 1.

[0026] After fixing the left vertical beam 11 to the ground, trestle, or artificial island as required by construction, control the two winches 12 in advance to unwind the steel wire rope 13, ensuring sufficient slack in the steel wire rope 13. Insert the left end of the first guide rail 15 into the mounting sleeve 17 and abut it against the left vertical beam 11. Align the threaded hole 18 of the mounting sleeve 17 with the threaded hole 16 of the guide rail 15. Rotate the bolt 19 through the threaded hole 18 and the threaded hole 16, fixing the mounting sleeve 17 to the first guide rail 15. Insert the left end of the second guide rail 15 into the mounting sleeve 14, which is fixedly connected to the right end of the first guide rail 15, so that the second guide rail... The threaded hole 16 of the track 15 is aligned with the threaded hole 18 of the mounting sleeve 14. Then, the first guide track 15 and the second guide track 15 are fixed together with bolts 19. Following the above method, multiple guide tracks 15 are assembled together. Finally, one end of the right vertical beam 11 is inserted into the rightmost mounting sleeve 14. The threaded hole 16 of the vertical beam 11 is aligned with the threaded hole 18 of the rightmost mounting sleeve 14. The rightmost vertical beam 11 and the rightmost guide track 15 are fixed together with bolts 19. The assembly of the support structure 1 is satisfied without disconnecting the trolley 110, the connecting shaft 111 and the wire rope 13.

[0027] In summary, the support structure 1 is composed of a second mounting sleeve 17, two vertical beams 11, multiple guide rails 15, multiple first mounting sleeves 14, and two winches 12. The coverage length of the support structure 1 can be set according to construction needs. The guide rails 15 and first mounting sleeves 14 are located on the rear side to provide a channel for connecting the winch structure 2. Therefore, a support mechanism can be installed at the bottom of the guide rails 15 to ensure the stability of the support structure 1.

[0028] By having one winch 12 work to wind up the wire rope 13 and another winch 12 work to unwind the wire rope 13, the trolley 110 moves left and right. The two fixed frames 21 in the winch structure 2 are fixedly connected to the two trolleys 110 respectively. The winch structure 2 and the suspended basket structure 3 installed on the winch structure 2, which are supported by the two trolleys 110, move left and right, thus expanding the effective working range of the suspended basket structure 3.

[0029] Example 2, as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown; Multiple connecting plates 22 are fixedly connected between the two fixed frames 21. The two fixed frames 21 are integrated. A hydraulic cylinder 29 is fixedly installed on one of the connecting plates 22. Telescopic rods 210 are fixedly installed on both connecting plates 22. The piston end of the telescopic rod 210 is fixedly connected to the limiting frame 211. The limiting frame 211 can move up and down through the hydraulic cylinder 29 and the telescopic rod 210. A hoisting assembly is provided between the two fixed frames 21 and the suspended basket structure 3.

[0030] In the hoisting assembly, the dual-shaft output geared motor 23 is fixedly installed at the bottom of the fixed frame 21. Both output ends of the dual-shaft output geared motor 23 are fixedly connected to the drive shaft 24. The winding frame 27, which is fixedly sleeved on the outside of the drive shaft 24, has a steel wire rope 28 fixedly installed inside. The bottom end of the steel wire rope 28 is fixedly connected to the outer frame 31. Two fixed frames 25 are rotatably sleeved on the outside of the drive shaft 24. The top of the fixed frames 25 is fixedly connected to the fixed frame 21. The fixed frames 25 support the drive shaft 24 to make the drive shaft 24 rotate stably. The brake 26, which is sleeved on the outside of the drive shaft 24, is fixedly connected to the fixed frame 21. After the control brake 26 is activated, the brake 26 brakes the drive shaft 24, stopping the drive shaft 24 and limiting its rotation. The rotation of the winding frame 27 is limited, and the top of the basket structure 3 is blocked and limited by the limiting frame 211. The up and down movement of the basket structure 3 is limited, reducing the swaying of the basket structure 3 and improving the stability of the basket structure 3.

[0031] A flat construction platform is pre-set, and the hydraulic cylinder 29 controls the up and down position of the limit frame 211. When the top of the suspended platform structure 3 contacts the limit frame 211, the bottom of the inner cavity of the outer frame 31 is aligned with the top of the construction platform. A fixed frame 3 212 is fixedly installed on the top of the limit frame 211. Then, the two control components are controlled to work. The pneumatic cylinder 213 in the control components is fixedly installed on the fixed frame 3 212. The relative position between the pneumatic cylinder 213 and the limit frame 211 remains unchanged. The piston end of the pneumatic cylinder 213 is fixedly connected to the top of the fixed frame 4 214, and a multi-axis gearbox 215 is fixedly connected to the top of the multi-axis gearbox 215. A drive motor 216 is fixedly connected to the top of the multi-axis gearbox 215. The output end of the drive motor 216 is fixedly connected to the input end of the multi-axis gearbox 215. Gear 1 217 is fixedly connected to the outer side of both output ends of the multi-axis gearbox 215. The drive motor 216 is controlled to work and output rotational force. The rotational force is acted on the two gears 1 217 under the action of the fixed frame 4 214, and the gears 1 217 rotate.

[0032] Two rotating shafts 218 are rotatably mounted on the fixed frame 214. The two rotating shafts 218 are fixedly connected to two positioning plates 221 respectively. After the top of the outer frame 31 abuts against the limiting frame 211, the two positioning plates 224 are fixedly set on the top front and top rear sides of the outer frame 31 respectively. A long groove 225 is opened on one side of the positioning plate 224. At this time, the two long grooves 225 move to both sides of the limiting frame 211. Since the long grooves 225 are relatively long in the left and right direction, during the upward movement of the suspended basket structure 3, the relative position between it and the limiting frame 211 is automatically restored under the influence of gravity. At this time, the long grooves 225 are located on the movement trajectory of the limiting frame 211. When the control component works, the pneumatic cylinder 213 pushes... The moving fixed frame 214, the rotating shaft 218 and the positioning plate 221 move. The limiting frame 211 passes through the long groove 225 and moves away from the positioning plate 224. When the pneumatic cylinder 213 extends to its limit, it controls the drive motor 216 to work. The two gears 217 rotate. Gears 219 are fixedly installed on the outside of the two rotating shafts 218. Gears 219 mesh with the adjacent gears 217. Under the action of gears 219, the rotating shaft 218 rotates. When the rotating shaft 218 and the positioning plate 221 rotate 90°, the drive motor 216 stops working and the positioning plate 221 stands upright. At this time, the vertical length of the positioning plate 221 is much greater than the vertical length of the long groove 225.

[0033] Subsequently, the pneumatic cylinder 213 in the control and positioning component retracts, and the two positioning plates 1 221 move towards the positioning plate 224. One of the positioning plates 1 221 in the control and positioning component has an installation groove 223 on the side near the positioning component. The pressure sensor 222 installed inside the installation groove 223 is fixedly connected to the positioning plate 1 221. When the pressure sensor 222 abuts against the positioning plate 224, the pressure value detected by the pressure sensor 222 increases. When the pressure values ​​detected by the two pressure sensors 222 reach the preset value, the pneumatic cylinder 213 stops working. At this time, the outer frame 31 is limited on both sides by the two positioning plates 224 and the four positioning plates 1 221. The forward and backward movement of the outer frame 31 is limited, providing a suspension positioning function for the suspended basket structure 3, further increasing the stability of the outer frame 31 during suspension, avoiding the shaking of the outer frame 31 during the process of personnel entering and exiting the inner part of the outer frame 31, ensuring the safety of personnel, and providing support and positioning for personnel to move low-weight goods and tools into the suspended basket structure 3.

[0034] When the suspended platform structure 3 needs to move up and down, the control drive motor 216 works again to drive the positioning plate 221 to rotate 90° and then stops working, causing the positioning plate 221 to fall down. At this time, the positioning plate 221 can pass through the inside of the long slot 225. The control pneumatic cylinder 213 works to drive the positioning plate 221 to reset, and then the two winch assemblies are controlled to control the suspended platform structure 3 to move up and down.

[0035] A support seat 220 is sleeved on the outside of the rotating shaft 218. The support seat 220 is fixedly connected to the limit frame 211. The support seat 220 increases the force points of the rotating shaft 218 and ensures the working stability of the rotating shaft 218.

[0036] Example 3, as Figure 1 , Figure 5 , Figure 11 , Figure 12 and Figure 13 As shown: Mesh element 2 35 is fixedly embedded on the left, right and top sides of the outer frame 31 to reduce the overall weight of the suspended basket structure 3. A base plate 36 is fixedly embedded at the bottom of the outer frame 31 to keep the bottom of the suspended basket structure 3 flat. Two door frames 32 are fixedly connected to the front and rear sides of the outer frame 31. A door body 33 is installed inside the door frame 32. Mesh element 1 34 is fixedly embedded on the door body 33. By controlling the door body 33 to open, personnel can easily enter the interior of the outer frame 31.

[0037] Limiting grooves 310 are provided on both sides of the loading tray 37. Limiting guide rails 311 are provided inside the limiting grooves 310. The two limiting guide rails 311 on both sides are fixedly connected to the outer frame 31. The two limiting guide rails 311 in the middle are fixedly connected to the outer frame 31 by a partition plate 312. Therefore, the loading tray 37 and the outer frame 31 are slidably installed. The structural dimensions of the loading tray 37 and the door 33 are preset. When the mesh part 34 is opened, the loading tray 37 can move out of the door frame 32 and leave the outer frame 31. Multiple reserved cavities 38 at the bottom of the loading tray 37 are provided with multiple rollers 39. The rollers 39 and The loading tray 37 is rotatably connected. When the bottom of the inner cavity of the outer frame 31 is aligned with the construction platform, the loading tray 37 can be pulled. The loading tray 37, supported by multiple rollers 39, moves away from the inside of the outer frame 31, allowing part of the loading tray 37 to move to the top of the construction platform. At this time, the loading tray 37 is well supported by the construction platform and is less obstructed on the outside of the outer frame 31, allowing for convenient and quick stacking of goods on top of the loading tray 37. After the goods on top of the loading tray 37 are loaded and unloaded, the loading tray 37 is pushed back into the outer frame 31. The multiple rollers 39 reduce the movement resistance of the loading tray 37, ensuring quick and convenient loading and unloading of goods in the suspended basket structure 3.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
