Description

Technical Field

[0001] This application relates to the technical field of light wells, and in particular to a self-elevating construction platform for light wells. Background Technology

[0002] A light well is a recessed space inward relative to the exterior wall of a building, used for lighting. During the construction of a light well, the exterior wall often needs to be plastered and tiled. Construction platforms are usually erected on each floor, and construction workers stand on the platforms to carry out the construction.

[0003] Regarding the aforementioned technologies, when constructing a light well, the construction materials need to be transported to the construction floor first, and then transferred from the construction floor to the construction platform for construction. The transportation distance is long, which makes the time consumption long and results in low construction efficiency. Summary of the Invention

[0004] To improve the construction efficiency of light wells, this application provides a self-elevating construction platform for light wells.

[0005] This application provides a self-elevating construction platform for light wells, employing the following technical solution:

[0006] A self-elevating construction platform for a light well includes a guide frame and a main support platform. The guide frame extends vertically along the height of the light well and encloses a movable space for the main support platform to move up and down. An adjustment device is provided between the guide frame and the main support platform. The adjustment device includes...

[0007] Connecting ropes are used for hoisting the main load-bearing platform;

[0008] A winding and unwinding power source is mounted on the top of the guide frame and is used to wind and unwind the connecting rope to drive the lifting and lowering of the load-bearing main platform;

[0009] A guide gear is installed on the main load-bearing platform and rotatably connected to the main load-bearing platform;

[0010] A guide rack is disposed on the guide frame, extends along the height of the guide frame, and meshes with the guide gear.

[0011] By adopting the above technical solution, the winding power source drives the connecting rope to wind up, causing the main support platform to move upward at the guide frame. Furthermore, the meshing of the guide gear and guide rack guides the vertical movement of the main support platform. This allows for rapid movement of personnel and materials during the construction of the skylight by directly transporting construction materials from the ground to the main support platform. Construction personnel and materials are placed on the main support platform and moved up and down within the skylight under its influence, thus improving the efficiency of skylight construction.

[0012] Optionally, the load-bearing main platform is provided with a rotation source, and at least one rotation source is provided. The rotation source is used to cooperate with the guide gear to drive the guide gear to rotate, so that the distance the guide gear moves relative to the guide rack is consistent with the distance the winding and unwinding power source drives the connecting rope to wind and unwind.

[0013] By adopting the above technical solution, the rotation source drives the guide gear to rotate, so that the cooperation between the guide gear and the guide rack has the power to move the load-bearing main platform, thereby improving the stability of the load-bearing main platform when it stops moving.

[0014] Optionally, the main load-bearing platform includes two main boards, the adjustment device is divided into two groups and controls the two main boards respectively, and each main board is connected to a secondary load-bearing platform. The main boards and the connected secondary load-bearing platforms together form a load-bearing structure.

[0015] The load-bearing sub-platform includes a support rod and a sub-plate. The upper end of the support rod is connected to the sub-plate, and the lower end of the support rod is detachably connected to the main plate. The sub-plate corresponds one-to-one with the main plate, and an active space is formed between the sub-plate and the main plate.

[0016] Both motherboards are equipped with locking components. When the motherboard in one of the support structures moves the sub-board in the same group to be opposite the motherboard in the other support structure, the sub-board is clamped between the guide frame and the motherboard of the other support structure, and the locking component on the motherboard of the other support structure can lock the sub-board.

[0017] By adopting the above technical solution, after one main board moves downwards and the secondary board locks relative to the other main board, one main board continues to move downwards to the bottom of the skylight for material loading. Construction workers can stand on the locked main and secondary boards to continue construction, thereby further improving construction efficiency. Furthermore, when construction workers stand on the main board, the secondary board in the same group as the main board can provide shade and rain protection for the workers and construction materials.

[0018] Optionally, the locking component includes a locking seat and a pushing source. The locking seat and the pushing source are installed inside the motherboard. The pushing source is connected to the locking seat to drive the locking seat to slide on the motherboard. The sub-board has a slot for the locking seat to be inserted.

[0019] By adopting the above technical solution, when the secondary board is opposite to another main board, the driving source will push the locking seat to be simultaneously inserted into the secondary board in order to limit the position of the secondary board.

[0020] Optionally, both motherboards have locking slots for locking sockets on adjacent motherboards to be inserted and engaged, and the locking sockets on the two motherboards are staggered so that the locking sockets on the two motherboards can be inserted and engaged with each other simultaneously.

[0021] By adopting the above technical solution, the two motherboards are connected to each other through locking sockets to improve the overall integrity of the two motherboards and make the connection between the two motherboards more tight when they are facing each other, thereby improving the stability of the load-bearing main platform.

[0022] Optionally, the support rod is rotatably connected to the sub-plate, the lower end of the support rod has a limiting block, the main plate has a connecting groove for the support rod and the limiting block to be inserted together, and the main plate has a limiting groove on the inner wall of the connecting groove for the limiting block to rotate into.

[0023] The sub-plate has a linkage component. When the locking seat is inserted into the sub-plate, it cooperates with the linkage component to drive the support rod to rotate, so that the limiting block moves from the limiting groove into the connecting groove.

[0024] By adopting the above technical solution, when the limiting block is in the limiting groove, it locks the support rod to the main board, allowing the main board to move along with the sub-board. The locking seat is inserted into the sub-board and cooperates with the linkage component. While locking the sub-board, the linkage component drives the limiting block to disengage from the limiting groove and enter the connecting groove. This allows the main board to disengage from the sub-board during movement, enabling the main board to move to the bottom of the skylight for loading, while the sub-board remains in position to cooperate with another main board.

[0025] Optionally, the linkage component includes

[0026] The linkage gear is located inside the sub-plate and is coaxially fixedly sleeved on the support rod;

[0027] The linkage rack slides within the sub-plate and meshes with the linkage gear;

[0028] The linkage seat slides within the sub-plate and is simultaneously connected to all the linkage racks on the same sub-plate;

[0029] A reset component, connected to the linkage seat, is used to drive the linkage seat to move, so that the linkage rack drives the linkage gear to rotate, and the limiting block rotates from the connecting groove to the limiting groove;

[0030] When the locking seat is inserted into the sub-plate, the locking seat pushes the linkage seat to move, causing the linkage rack to drive the linkage gear to rotate, and the limiting block to rotate from the limiting groove to the connecting groove.

[0031] By adopting the above technical solution, the locking seat pushes the linkage seat, which in turn moves the linkage rack, causing the linkage gear meshing with the linkage rack to rotate. This, in turn, drives the support rod fixed to the linkage gear to rotate, allowing the limit block to move from the limit groove to the connecting groove. Furthermore, when the locking seat separates from the linkage seat and the main board and support rod are engaged, the sub-board separates from the other main board. The reset component moves the linkage seat, causing the limit block to rotate into the limit groove, thus reconnecting the support rod to the main board. During the main board's movement to engage with the other main board, the sub-board is simultaneously moved.

[0032] Optionally, the linkage seat is connected to a positioning strip located within the sub-plate. The end of the positioning strip has positioning teeth facing one of the guide racks. When the linkage seat drives the limiting block to rotate from the limiting groove to the connecting groove, the linkage seat drives the end of the positioning strip to pass through the sub-plate so that the positioning teeth mesh with the positioning rack.

[0033] By adopting the above technical solution, the engagement of the positioning strip and the positioning teeth can lock the sub-plate and the guide frame, thereby improving the stability of the sub-plate.

[0034] Optionally, when the sub-plate of one of the bearing structures is locked to the main plate of the other bearing structure, the upper surface of the sub-plate is flush with the upper surface of the main plate.

[0035] Optionally, the guide frame is connected to a plurality of reinforcing seats that abut against the outer wall of the light well along its own height direction.

[0036] By adopting the above technical solution, the stability of the guide frame is improved by strengthening the seat to make the guide frame supported by the light well.

[0037] In summary, this application includes at least one of the following beneficial effects:

[0038] 1. The load-bearing main platform, in conjunction with the guide frame and the adjusting device, can move up and down in the light well to adjust its position, thereby enabling the construction materials and personnel on the load-bearing main platform to move quickly, reducing the material handling distance and improving the construction efficiency of the light well.

[0039] 2. Construction workers stand on one main board to carry out construction, while the other main board can move downwards to load materials, thus enabling construction workers to work continuously and further improving the construction efficiency of light wells. Attached Figure Description

Detailed Implementation

[0050] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0051] This application discloses a self-elevating construction platform for light wells. (Refer to...) Figure 1The light well 1 forms a U-shaped recessed space relative to the building's exterior wall. The self-elevating construction platform of the light well includes a guide frame 2 and a load-bearing main platform 3. The guide frame 2 is erected in the light well 1 and encloses a movable space. The load-bearing main platform 3 is used to support construction personnel and materials. The outer wall of the load-bearing main platform 3 abuts against the inner wall of the guide frame 2, and an adjustment device 4 is installed between the load-bearing main platform 3 and the guide frame 2. The adjustment device 4 moves the load-bearing main platform 3 up and down in the movable space to adjust its height position within the light well.

[0052] Reference Figure 1 and Figure 2 The guide frame 2 includes vertical rods 201 and mounting plates 202. The vertical rods 201 are rods extending vertically, fixed to the ground, and multiple vertical rods 201 are distributed circumferentially around the skylight 1. Between adjacent vertical rods 201, there is space for operators to work on the exterior wall of the skylight 1. Movement space is formed between the multiple vertical rods 201. The load-bearing main platform 3 is square, with vertical rods 201 on each of its four circumferential side walls. The distance between the outer wall of the load-bearing main platform 3 and the outer wall of the skylight 1 is less than 15cm to prevent workers from easily slipping when approaching the outer wall of the skylight 1. The mounting plate 202 is square and fixed to the top of the multiple vertical rods 201. The mounting plate 202 is located on the top floor of the building, extending around its perimeter and fixed to the surface of the top floor with bolts.

[0053] Multiple reinforcing seats 18 are evenly spaced vertically on the outer wall of the vertical rod 201 away from the moving space. The reinforcing seats 18 are block-shaped and fixed to the outer wall of the light well 1. The reinforcing seats 18 can be fixed to the light well 1 by first embedding them in the wall of the light well 1 and then welding them to the vertical rod 201; or the reinforcing seats 18 can be fixed to the vertical rod 201 first and then fixed to the wall of the light well 1 by bolts. In this embodiment, a steel plate is embedded in the wall, and the reinforcing seats 18 are installed on the steel plate by bolts to fix the reinforcing seats 18 relative to the wall. Then the reinforcing seats 18 are welded to the vertical rod 201. After construction is completed, the reinforcing seats 18 and the guide frame 2 are removed from the wall.

[0054] Reference Figure 1 and Figure 2The positioning device 4 includes a connecting rope 41, a winding / unwinding power source 42, a guide gear 43, and a guide rack 44. The winding / unwinding power source 42 is fixedly installed on the mounting plate 202 and corresponds one-to-one with the wire ropes. It is used to wind and unwind the connecting rope 41. One end of the connecting rope 41 passes downward through the mounting plate 202 and is fixedly hoisted and connected to the main support platform 3. The winding / unwinding power source 42 is an electric hoist wire rope winder fixedly mounted on the mounting plate 202. The connecting rope 41 is a wire rope. When the winding / unwinding power source 42 unwinds the connecting rope 41, the main support platform 3 moves downward under its own weight. Conversely, when the winding / unwinding power source 42 winds the connecting rope 41, it pulls the main support platform 3 upward.

[0055] Reference Figure 2 and Figure 3 A vertical groove is formed on the side of the vertical rod 201 facing the moving space. A guide rack 44 corresponds to and is fixedly installed in the corresponding groove of the vertical rod 201. The teeth of the guide rack 44 are distributed vertically. A guide gear 43 is rotatably connected to the periphery of the main support platform 3, and the number and position of the guide gears 43 correspond one-to-one with the vertical rods 201. The axis of the guide gear 43 extends horizontally, and one side of the guide gear 43 protrudes outward from the outer wall of the main support platform 3. The portion of the guide gear 43 protruding from the main support platform 3 enters the corresponding groove of the vertical rod 201 and meshes with the guide rack 44. During the up-and-down movement of the main support platform 3 via the connecting rope 41, the winding power source 42 drives the guide gear 43 to rotate and move relative to the guide rack 44, thus guiding the up-and-down movement of the main support platform 3.

[0056] Reference Figure 3 and Figure 4 Furthermore, the guide gears 43 on both sides of the main support platform 3 are each equipped with a rotation source 5 mounted on the main support platform 3. The rotation source 5 is a rotating motor fixedly embedded in the side of the main support platform 3, and the rotating motor can rotate in both directions. The guide gears 43 are rotatably connected to the main support platform 3 via a rotating shaft. The guide gears 43 and the rotating shaft are relatively fixed, and the output shaft of the rotating motor is relatively fixed to the rotating shaft, so that the rotating motor can drive the guide gears 43 to rotate. Figure 2 This causes the guide gear 43 to move actively relative to the guide rack 44, thereby driving the load-bearing main platform 3 to move up and down. Furthermore, the rotational speed of the motor is coordinated with the winding and unwinding distance of the winding and unwinding power source 42. When the winding and unwinding power source 42 drives the connecting rope 41 to wind upwards, the motor drives the guide gear 43 to move upwards relative to the guide rack 44 by the same distance; conversely, when the connecting rope 41 is unwinding downwards, the guide gear 43 moves downwards relative to the guide rack 44 by the same distance.

[0057] Reference Figure 2 and Figure 3Furthermore, the load-bearing main platform 3 includes two main plates 31, both of which are square plates and symmetrically arranged along the center of the load-bearing main platform 3. The adjustment devices are divided into two groups, with two sets of adjustment devices 4 used to control the vertical movement of the two main plates 31. Each main plate 31 has a vertical rod 201 corresponding to its three sidewalls, excluding the sidewall opposite to the adjacent main plate 31. Each set of adjustment devices 4 has two winding / unwinding power sources 42 and two connecting ropes 41, which are respectively connected to the opposite ends of the corresponding main plate 31. By controlling the vertical movement of the two main plates 31 through the two sets of adjustment devices 4, the heights of the two main plates 31 can be different.

[0058] During construction, construction materials such as tiles are placed on two main boards 31. Construction workers stand on the main boards 31 and use the materials on the main boards 31 to construct the light well 1 on the same side. When the construction materials on one main board 31 are used up, the construction workers stand on the other main board 31 to construct the other side of the light well 1. The adjustment device 4 controls the main board 31 without supporting materials to move down to the ground to load materials. After the main board 31 is loaded, it is moved back to a position level with the other main board 31 so that the construction workers can carry out construction without interruption.

[0059] Reference Figure 3 and Figure 5 To prevent workers from accidentally stepping into empty spaces when a main board 31 moves downwards for loading, each main board 31 is equipped with a supporting sub-platform 6 to fill in the gaps in its position. Each supporting sub-platform 6 corresponds one-to-one with a main board 31, and the main board 31 and its corresponding supporting sub-platform 6 together form a load-bearing structure.

[0060] The load-bearing sub-platform 6 includes support rods 61 and sub-plates 62. Sub-plates 62 correspond one-to-one with the main plates 31 in the same load-bearing assembly and are located above the corresponding main plates 31. Sub-plates 62 are square plates with the same dimensions as the corresponding main plates 31, and the vertical projection of sub-plates 62 coincides with the main plates 31 in the same group. Connecting ropes 41 slide through sub-plates 62 and connect to main plates 31. Support rods 61 support the main plates 31 and the corresponding sub-plates 62, so that an activity space 7 for personnel to walk and materials to be placed is formed between the main plates 31 and sub-plates 62. Support rods 61 are round rods with their axes extending vertically. Each main plate 31 has multiple support rods 61, which are distributed at opposite ends of the sub-plates 62. The support rods 61 at each end are spaced apart along the edge of the end of the sub-plate 62, and one end of the support rod 61 is opposite to the side opening of the light well 1 to form a fence that restricts personnel from moving out.

[0061] The upper end of the support rod 61 is connected to the sub-plate 62, and the lower end of the support rod 61 is detachably connected to the main plate 31. Both main plates 31 have locking components, which are used to lock the sub-plate 62 in different load-bearing structures than the main plate 31.

[0062] During the downward movement of the main board 31 in one of the support structures, the main board 31 drives the secondary board 62 downward via the support rod 61. When the secondary board 62 moves downward to face the main board 31 in another support structure, the secondary board 62 is clamped between the vertical rod 201 and the main board 31 of the other support structure, and the upper surface of the secondary board 62 is flush with the upper surface of the main board 31 of the other support structure. At this time, the downward-moving main board 31 stops moving, and the locking component on the main board 31 of the other support structure locks the secondary board 62. The stopped main board 31 is then unlocked and disassembled from the support rod 61 of the same group. Then the main board 31 continues to move downward so that it moves to the ground for material loading, and the secondary board 62 fills in the original position of the main board 31. In another embodiment, a 1m baffle (not shown in the figure) can be fixed on the side of the upper surface of the main board 31 and the secondary board 62 near the opening of the light well 1 to protect the construction personnel.

[0063] Reference Figure 5 and Figure 6 The locking assembly includes a locking seat 8 and a pushing source 9. The locking seat 8 slides within the main board 31, and the pushing source 9 is installed within the main board 31 and connected to the locking seat 8 to provide power for the locking seat 8 to move. The sub-board 62 has a slot 10 for the locking seat 8 to be inserted into, so that the locking seat 8 in one set of load-bearing components can be inserted into the sub-board 62 in another set of load-bearing components by cooperating with the slot 10.

[0064] Specifically, each locking seat 8 corresponds one-to-one with a main board 31. In this embodiment, the locking seat 8 includes a locking rod 81 and a push rod 82. Each locking seat 8 has one push rod 82 and three locking rods 81. The push rod 82 extends horizontally, and its length direction is perpendicular to the distribution direction of the two main boards 31 when they are facing each other. The locking rods 81 are evenly spaced and fixed to the side wall of the push rod 82 facing the other bearing structure, and their extension length direction is parallel to the distribution direction of the two main boards 31 when they are facing each other. The driving source 9 is an electric telescopic rod installed in the main board 31. The base of the electric telescopic rod is fixed to the main board 31, and the axis of the telescopic end of the electric telescopic rod extends along the distribution direction of the two main boards 31 when they are facing each other. The telescopic end of the electric telescopic rod is connected to the push rod 82.

[0065] Reference Figure 6 The main board 31 has a mounting groove 19, a first guide groove 20, and a second guide groove 21 sequentially connected along the direction close to the other bearing assembly. The mounting groove 19 is used to mount the electric telescopic rod, the first guide groove 20 is used for sliding the push rod 82, and the second guide groove 21 corresponds to the locking rod 81 and is used for sliding the locking rod 81. The mounting groove 19 passes through the side of the main board 31 away from the other bearing assembly to allow the electric telescopic rod's wire to extend, and the second guide groove 21 passes through the side of the main board 31 facing the other bearing assembly. Furthermore, to facilitate the assembly of the locking components, the main board 31 is welded together from two sections.

[0066] Reference Figure 5 and Figure 6 The slot 10 includes three sub-slots 101, each corresponding to one of the three locking rods 81 in another bearing assembly. When the telescopic end of the electric telescopic rod is retracted, the locking seat 8 is stored in the main board 31. When the main board 31 of one bearing assembly is opposite the sub-board 62 of the other bearing assembly, the second guide groove 21 on the main board 31 corresponds to and connects with the sub-slots 101 on the sub-board 62. At this time, the telescopic end of the electric telescopic rod on the main board 31 is extended, causing the three locking rods 81 on the main board 31 to be inserted into the sub-slots 101 of the sub-board 62, so that the main board 31 of one bearing assembly is locked to the sub-board 62 of the other bearing assembly.

[0067] In other embodiments, the locking seat 8 may also include only three locking rods 81, which are separated from each other. The driving source 9 is an electric telescopic rod that corresponds one-to-one with the locking rod 81. The telescopic end of the electric telescopic rod is directly connected to the locking rod 81 to drive the locking rod 81 to move.

[0068] Reference Figure 4 and Figure 7 In order to lock the sub-plate 62 of one bearing assembly with the main plate 31 of another bearing assembly, the support rod 61 of the same bearing assembly as the sub-plate 62 is separated from the main plate 31 of the same assembly. The support rod 61 is rotatably connected to the sub-plate 62. A limit block 12 is fixed on the outer wall of the bottom end of the support rod 61. The limit block 12 is square in shape. The bottom end of the support rod 61 is locked with the main plate 31 of the same bearing assembly through the limit block 12. The sub-plate 62 is provided with a linkage component 15. When the sub-plate 62 of one bearing assembly is inserted by the locking seat 8 of another bearing assembly, the locking seat 8 of the other bearing assembly cooperates with the linkage component 15 on the sub-plate 62 of one bearing assembly to unlock the support rod 61 and the main plate 31 of the same bearing assembly as the sub-plate 62.

[0069] Reference Figure 7 and Figure 8 Specifically, the upper surface of the motherboard 31 has connecting slots 13 that correspond one-to-one with the support rods 61 in the same group, allowing the support rods 61 and the limiting blocks 12 to be inserted together. Combined with... Figure 4 The main board 31 has a limiting groove 14 on the inner side wall of the connecting groove 13 for the limiting block 12 to rotate into. When the support rod 61 rotates to drive the limiting block 12 to rotate into the limiting groove 14, the support rod 61 is locked with the main board 31.

[0070] The linkage assembly 15 includes a linkage gear 151, a linkage rack 152, a linkage seat 153, and a reset member 154. The linkage gear 151 is located inside the sub-plate 62 and corresponds one-to-one with the support rod 61. The linkage gear 151 is fixedly and coaxially sleeved on the top of the corresponding support rod 61. Each linkage assembly 15 has two linkage racks 152, which slide at opposite ends of the sub-plate 62. The sub-plate 62 has a first sliding groove 22 for the linkage racks 152 to slide, and the length direction of the linkage racks 152 is parallel to the extension direction of the end edge of the sub-plate 62. The linkage racks 152 at each end of the sub-plate 62 simultaneously mesh with all the linkage gears 151 at the same end of the sub-plate 62.

[0071] The linkage seat 153 slides within the sub-plate 62 along the length of the linkage rack 152. The sub-plate 62 has a second sliding groove 23 for the linkage seat 153 to slide. The linkage seat 153 is elongated, and its length is perpendicular to the length of the linkage rack 152. The linkage seat 153 is fixed to the ends of two linkage racks 152 within the same sub-plate 62. The linkage seat 153 is fixed to one end of the linkage rack 152 near the other bearing assembly, so that when the linkage seat 153 moves, it drives the linkage rack 152 to move together, thereby driving the linkage gear 151 within the sub-plate 62 to rotate, and in turn driving the support rod 61 to rotate.

[0072] Reference Figure 5 and Figure 7 The reset component 154 is a spring installed within the sub-plate 62. The sub-plate 62 has a mounting groove 24 for assembling the spring, which connects the second slide groove 23 and the slot 10. One end of the spring is connected to the inner wall of the mounting groove 24, and the other end is connected to the linkage seat 153. The spring force pushes the linkage seat 153 to move closer to the other bearing assembly, causing the linkage seat 153 to press against the side of the second slide groove 23 closest to the other bearing assembly, thus engaging... Figure 4 At this time, the limiting block 12 is locked in the limiting groove 14. In order to facilitate the assembly of the linkage component 15, the sub-plate 62 is made by welding the two halves together.

[0073] Reference Figure 5 and Figure 6 When the sub-board 62 of the first-mounted assembly moves to face the main board 31 of the second-mounted assembly, the telescopic end of the electric telescopic rod in the same group as the main board 31 extends to insert the locking rod on the main board 31 into the sub-board 62 through its engagement with the slot 10, thus combining... Figure 7 Furthermore, the locking lever of the main board 31 abuts against the linkage seat 153 of the sub-board 62, thereby driving the linkage seat 153 of the sub-board 62 and the linkage rack 152 to move together toward the compression spring.

[0074] Reference Figure 5 and Figure 6When the telescopic end of the electric telescopic rod of the main board 31 is fully extended, the linkage gear 151 of the sub-board 62, driven by the linkage rack 152, engages... Figure 4 and Figure 8 The support rod 61 rotates until the limiting block 12 enters the connecting groove 13, thereby unlocking the support rod 61 on the sub-plate 62 from the main plate 31 of the same bearing assembly. This prevents the sub-plate 62 from moving downwards when the main plate 31 moves downwards. Furthermore, when the main plate 31, after loading materials, moves upwards to engage with the support rod 61, the electric telescopic rod of the other bearing assembly retracts, disengaging the locking seat 8 from the sub-plate 62. The spring force on the sub-plate 62 drives the linkage seat 153 to move, causing the limiting block 12 to re-insert into the limiting groove 14, thus relocking the sub-plate 62 and the main plate 31 in the same assembly.

[0075] Reference Figure 7 and Figure 9 Furthermore, a positioning strip 16 is fixedly connected to the middle of the linkage seat 153 and slides within the sub-plate 62 along with the linkage seat 153. The positioning strip 16 is parallel to the linkage rack 152, and the end of the positioning strip 16 away from the linkage seat 153 has positioning teeth 17. Figure 4 and Figure 8 When the linkage seat 153 is pushed to the position where the limit block 12 enters the connecting groove 13, the linkage seat 153 drives the end of the positioning strip 16 away from the linkage seat 153 to move out of the sub-plate 62, thus combining Figure 2 The end of the positioning bar 16 away from the linkage seat 153 is inserted into the receiving groove of the opposite vertical rod 201, so that the positioning teeth 17 mesh with the positioning rack, thereby further locking the sub-plate 62.

[0076] Reference Figure 6 Furthermore, each of the two motherboards 31 has a locking slot 11 for engaging with the locking rod 81 on the adjacent motherboard 31. The locking slot 11 corresponds one-to-one with the locking rod 81, and the positions of the locking rods 81 on the two motherboards 31 are staggered. The locking slot 11 and the second guide groove 21 on the motherboard 31 are alternately arranged. Therefore, when the two motherboards 31 are on the same horizontal plane, the locking seats 8 on both motherboards 31 can be inserted into the adjacent motherboard 31, thereby locking the two motherboards 31 together and further improving the stability of the motherboards 31.

[0077] After the construction of the light well 1 is completed, the guide frame 2 can be left in place for subsequent enclosure use, or it can be dismantled.

[0078] The implementation principle of a self-elevating construction platform for a light well according to this application embodiment is as follows: Construction materials are placed on the main board 31, and construction personnel stand on the main board 31. The winding and unwinding power source 42 drives the connecting rope 41 to wind and unwind, thereby moving the main board 31 in the light well 1 to the construction height. When the construction materials on one main board 31 are used up, the main board 31 moves downward until the auxiliary plate 62 is opposite to another main board 31. The other main board 31 locks the auxiliary plate 62 through the locking seat 8 and unlocks the auxiliary plate 62 from the main board 31 in the same group. Then the main board 31 continues to move downward to the ground to load materials, while the construction personnel continue construction using the construction materials on the other main board 31. When the loaded main board 31 moves upward to engage with the support rod 61 in the same group, the locking seat 8 on the other main board 31 is separated from the auxiliary plate 62, so that the auxiliary plate 62 is re-locked to the main board 31 in the same group. Then the main board 31, which is now carrying construction materials again, continues to move upward to a position flush with the other main board 31. The two main boards 31 are locked together by the locking seat 8.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
