Description

Technical Field

[0001] This invention relates to the field of elevator construction, and in particular to a side-door access construction platform. Background Technology

[0002] Elevators are common vertical transportation devices in high-rise buildings, quickly transporting passengers to designated floors. In the traditional construction industry, elevator installation is mostly achieved by erecting scaffolding within the elevator shaft. However, this method is cumbersome, time-consuming, inefficient, and unsafe. While construction platforms that can be moved by steel cables are now used to assist installation, traditional elevators have doors and tracks located on different sides of the car, with similar length and width, offering ample space. Using such platforms to install side-entry elevators presents challenges, including confined space, increased difficulty and danger, and ultimately fails to meet practical needs. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a side-door access construction platform, which has the advantages of simple structure and high safety.

[0004] A side-door access construction platform, comprising:

[0005] The lifting device has a support frame on which a hoist is installed. The hoist works with a wire rope to drive the support frame to move up and down. Guide shoes are arranged at both ends of the support frame along a first direction and slide in cooperation with the elevator track. The main frame includes a main base frame set on the support frame and a main canopy set on the main base frame, forming a main working space for construction personnel to move around. Both the main base frame and the main canopy are provided with through holes corresponding to the steel wire ropes. The main canopy has a main top plate, and the main top plate is provided with clearance grooves on both sides along the first direction, corresponding to the elevator track spacing. The first auxiliary frame includes a first auxiliary base frame and an auxiliary canopy disposed on the first auxiliary base frame, forming an auxiliary working space that communicates with the main working space. The first auxiliary base frame slides with the main frame along a second direction, which is perpendicular to the first direction in a plane. The auxiliary canopy moves with the first auxiliary base frame.

[0006] This invention discloses a side-door access construction platform, which can be used for construction in elevator shafts with side-door access. Its telescopic frame structure allows it to adapt to shafts of various sizes, improving the platform's versatility. Furthermore, the platform enhances worker safety by incorporating a canopy to prevent falling objects and obstacle avoidance grooves corresponding to the elevator tracks.

[0007] Furthermore, the main frame also includes protective tubes corresponding to the perforations, which are sandwiched between the main base frame and the main roof, and sleeved over the wire rope. This structure facilitates disassembly and installation, and provides protection for the wire rope.

[0008] Furthermore, the main base frame includes two first sliding main rods and two second sliding main rods arranged side by side, each located on both sides of the main working space. The first sliding main rods are fixed to the top of the support frame, and the second sliding main rods are fixed to the first sliding main rods via a first guardrail. The first sub-base frame includes a first sliding auxiliary rod slidably connected to the first sliding main rod and a second sliding auxiliary rod slidably connected to the second sliding main rod. An entrance / exit for construction personnel is formed between the first and second sliding auxiliary rods. The sub-canopy is provided on the second sliding auxiliary rod, and the middle part of the second sliding auxiliary rod arches away from the first sliding auxiliary rod to form a gate-shaped structure. The structure is simple, achieves overall lightweighting of the construction platform, and facilitates access for construction personnel.

[0009] Furthermore, a connecting support frame is provided on the first sliding auxiliary rod. Two connecting frames are symmetrically arranged on both sides of the first auxiliary rod at both ends of the connecting support frame. Each connecting frame includes a second guardrail, a third guardrail, and a gatepost. The second and third guardrails are spaced apart, forming a channel communicating with the entrance / exit. A limit block is provided on the third guardrail. The gatepost is rotatably mounted on the second guardrail, and its abutting end is engaged with the limit block. Its structure is simple and stable, and its operation is convenient.

[0010] Furthermore, the abutting end of the gate rod is provided with a first positioning hole, and the limiting block is provided with a second positioning hole corresponding to the first positioning hole. When the abutting end of the gate rod is engaged with the limiting block, the first positioning hole and the second positioning hole are coaxial. This structure ensures that when one side of the entrance / exit is open, the other side of the entrance / exit is closed, thereby guaranteeing the safety of construction personnel.

[0011] Furthermore, the main roof plate includes two first roof plates and a second roof plate distributed along the second direction and spliced ​​together. The first and second roof plates are symmetrically arranged, and each has a first groove at its splicing point, thereby forming the through hole when spliced ​​together. The first and second roof plates also have a second groove at their splicing points, and after splicing, the second grooves are connected to form the clearance groove. The main roof also includes a telescopic frame, and the first and second roof plates are fixedly mounted on the telescopic frame. This structure allows for structural adjustments and improves the versatility of the construction platform.

[0012] Furthermore, the support frame is also equipped with a safety lock that works with the wire rope. The main base frame has a main base plate, which includes a first base plate and a second base plate that are spliced ​​together along the second direction. The first base plate has two first maintenance holes corresponding to the hoist, and the second base plate has a second maintenance hole corresponding to the safety lock. This structure facilitates the maintenance and observation of the hoisting device by construction personnel.

[0013] Furthermore, the secondary canopy includes a third top plate, a connecting angle steel disposed on the top surface of the third top plate and corresponding to the second sliding auxiliary rod, and a reinforcing rod spanning between the two connecting angle steels. This structure can improve the structural strength of the secondary canopy.

[0014] Furthermore, the platform also includes a second auxiliary frame that slides with the main frame. The second auxiliary frame and the first auxiliary frame are located on opposite sides of the main frame, with an auxiliary support rod inserted through them. The auxiliary support rod is fixed to the second auxiliary frame by a U-shaped clamp. The connecting support frame is fixed to the first sliding auxiliary rod by a U-shaped clamp. A supporting angle steel extending along the second direction is provided in the platform. The supporting angle steel is placed on top of the auxiliary support rod and the connecting support frame and is detachably connected to them. This structure can limit the movement of the second auxiliary frame, preventing it from slipping off the main frame due to downward tilting under gravity, thus improving the safety and stability of the construction platform.

[0015] Furthermore, the support frame includes a horizontally extending support tube and telescopic rods slidably sleeved at both ends of the support tube. The main frame is fixedly mounted on the support tube. Push plates are provided at the ends of the telescopic rods, and guide shoes are provided on the outer surfaces of the push plates. The guide shoes cooperate with the elevator tracks laid in the shaft. A rotating rod rotatably passes through the middle of the support tube and is fixed to a first bevel gear. A second bevel gear meshing with the first bevel gear is sleeved on a screw. The left and right ends of the screw are provided with reverse threads. The left end of the screw is threaded to a first sleeve rod, and the right end is threaded to a second sleeve rod. The first and second sleeve rods are respectively fixed to the push plates located at both ends of the support tube, thereby driving the guide shoes at both ends to simultaneously move closer to or away from the elevator tracks. Its structure is simple and stable. The symmetrical extension and retraction of the telescopic rods ensures that the construction platform is located in the middle of the shaft, thus ensuring the stability of the construction platform's lifting and lowering.

[0019] This invention discloses a side-door entry / exit construction platform for installing a side-door elevator. The elevator shaft 11 is surrounded by a wall 12 or a structure consisting of a wall 12 and a viewing glass 13, extending vertically to allow the elevator to move up and down within the shaft 11 to reach different floors. The elevator track 14 is composed of multiple guide rails joined vertically, typically two of which are symmetrically arranged on the left and right walls of the shaft 11. Guide shoes and other structures are installed on the elevator, slidingly engaging with the elevator track 14 to guide and limit the elevator's movement. Openings 15, corresponding to the elevator door, are also provided on the left or right wall of the shaft 11 for passengers to enter and exit the elevator. During construction, these openings 15 can serve as material handling entrances and exits. In this embodiment, there are two shafts 11 arranged symmetrically, with openings 15 on the side of each shaft 11 furthest from the other. Since the elevator door and the elevator track 14 are on the same side, compared with the traditional elevator shaft 11, this type of side-door elevator shaft 11 has the problem of smaller size and narrower construction space in the left and right direction (defined as the first direction X), which increases the difficulty and danger of construction operations in the shaft 11, and the existing construction platform cannot meet the construction needs.

[0020] The side-entry construction platform of this invention includes a lifting device 2, a main frame 3, a first auxiliary frame 4, and a connecting frame 5. The lifting device 2 works in conjunction with a steel wire rope a suspended in the shaft 11, thereby driving the entire lifting device 2 to move up and down along the steel wire rope a. The main frame 3 is mounted on the lifting device 2 and moves up and down with it, allowing construction workers to stand in the main frame 3 and perform construction work at different heights within the shaft 11. The first auxiliary frame 4 is slidably mounted on one side of the main frame 3 along a second direction Y to accommodate shaft 11 structures of different sizes. The second direction Y is perpendicular to the first direction X in the plane, allowing construction workers to move between the main frame 3 and the first auxiliary frame 4, thus enabling them to perform construction work in different directions.

[0021] The lifting device 2 includes a support frame 21, a hoist 22, a safety lock 23, and a telescopic assembly. The support frame 21 includes two sets of horizontal beams 211 spaced apart along the height direction, and at least two vertical columns 212 positioned between the two sets of horizontal beams 211. The two ends of each column 212 are welded and fixed to the two sets of horizontal beams 211 respectively. Each set of horizontal beams 211 includes two parallel and horizontally extending support pipes 2111 and telescopic rods 2112 slidably fitted at both ends of the support pipes 2111. The two support pipes 2111 are fixed together by a connecting plate 213, forming a receiving space 214 between them. The telescopic assembly is installed in the receiving space 214. The two telescopic rods 2112 located at the same end are connected together by a push plate 215. A guide shoe 216 is provided on the outer side of the push plate 215. The guide shoe 216 cooperates with the elevator track 14 laid in the shaft 11, serving as a limiting and guiding element for the lifting and lowering movement of the construction platform. The structure of the guide shoe 216 is similar to that of the guide shoe 216 used in elevators, and will not be described in detail here.

[0022] The telescopic assembly includes a rotating rod 241, which rotatably passes through the middle of the support tube 2111. One end of the rotating rod 241 is used to engage with tools such as wrenches, and the other end is located in the receiving space 214 and fixed to the first bevel gear 242. A connecting plate 213 is rotatably mounted with a screw 243 via a bearing. A second bevel gear 244 is sleeved on the screw 243 and meshes with the first bevel gear 242. The rotating rod 241 drives the second bevel gear 244 to rotate through the first bevel gear 242, thereby driving the screw 243 to rotate. The left and right ends of the screw 243 are provided with reverse threads. The left end of the screw 243 is threaded to the first sleeve rod 245, and the right end of the screw 243 is threaded to the second sleeve rod 246. The first sleeve rod 245 and the second sleeve rod 246 are respectively fixed to the push plates 215 located at both ends of the support tube 2111. When the screw 243 rotates, the first sleeve and the second sleeve move in opposite directions, driving the telescopic rods 2112 at both ends to slide in opposite directions at the same speed, causing the guide shoe 216 to move closer to or away from the elevator track 14, thereby realizing the length adjustment of the lifting device 2.

[0023] The hoist 22 and safety lock 23 are mounted on the support frame 21. The hoist 22 is a dedicated hoist for elevator installation and construction platforms. There are two hoists 22, spaced apart along a direction perpendicular to the first direction X. Each hoist 22 is connected to a steel wire rope a, thereby achieving stable lifting and lowering using these two steel wire ropes a. The safety lock 23 is located on one side of the line where the hoists 22 are located and is connected to a steel wire rope a, forming an isosceles triangle layout with the two hoists 22 (the safety lock 23 is located at the vertex). The hoist 22 and safety lock 23 are common lifting and protection devices in the art, and their structure will not be described in detail here.

[0024] The main frame 3 is fixedly mounted on the crossbeam 211 and includes a main base frame 31, side supports 32 and a main canopy 33. There are two sets of side supports 32, which are respectively set on both sides of the base frame along the first direction X. The main canopy 33 covers the top of the side supports 32, thereby forming a main working space in the middle for construction personnel to move around.

[0025] The main base frame 31 includes a first sliding main rod 311 fixed to the top of the support frame 21. There are two first sliding main rods 311 located on both sides of the main working space. A main base plate for supporting construction personnel is provided between the first sliding main rods 311. The main base plate can be made of a single plate. In this embodiment, the main base plate includes a first base plate 312 and a second base plate 313 spliced ​​together. The splicing direction and splicing form of the first base plate 312 and the second base plate 313 can be selected according to the actual situation. In this embodiment, the first base plate 312 and the second base plate 313 are distributed along the second direction Y, and the first base plate 312 and the second base plate 313 have through holes corresponding to the wire rope a at the splicing line. Specifically, the first base plate 312 has two first through holes 3121. The wire rope a passing through the first through hole 3121 cooperates with the hoist 22. The second base plate 313 has one second through hole 3131. The second through hole 3131 is located between the first through hole 3121 and the second through hole 3131. The wire rope a passing through the second through hole 3131 cooperates with the safety lock 23.

[0026] Preferably, the first base plate 312 has two first maintenance holes 3122 corresponding to the hoist 22, and the second base plate 313 has a second maintenance hole 3132 corresponding to the safety lock 23. The first maintenance holes 3122 and the second maintenance holes 3132 facilitate maintenance personnel to maintain and observe the hoist 22 and the safety lock 23 in the work space.

[0027] Two side guards 32 are welded to the two first sliding main rods 311 respectively, including a second sliding main rod 321 parallel to the first sliding main rods 311. The first sliding main rods 311 and the second sliding main rods 321 are connected by a baffle 323 or a rod 322, forming a protective barrier for construction personnel to prevent them from falling into the shaft 11. The connection structure of the baffle 323 or the rod 322 can be designed according to the actual situation. In this embodiment, the rod 322, the first sliding main rod 311, and the second sliding main rod 321 form a grid-like structure, and the baffle 323 is fixed to the first sliding main rod 311.

[0028] The main canopy 33 includes two sets of telescopic frames connected to two side supports 32 respectively, and a main roof plate covering the telescopic frames. Each telescopic frame includes two outer support rods 331 fixedly installed on the outside of the side supports 32 and inner support rods 332 slidably fitted within the outer support rods 331. The height of the main roof plate is adjusted by sliding the inner support rods 332 to keep the main frame 3 as low as possible, preventing large-scale swaying and improving stability. The tops of the two inner support rods 332 are connected by a first connecting rod 333, and the two outer support rods 331 are connected by a second connecting rod 334. The main roof plate is fixed to the two first connecting rods 333. The main roof plate can be a single, complete plate structure or composed of multiple panels. The main roof plate also has three third through holes for threading steel wire ropes a.

[0029] To address this, clearance grooves are provided on both sides of the main ceiling. The shape and size of the clearance grooves can be designed according to the cross-section of the elevator track. When the elevator track tilts during installation, the construction personnel can control the tilting direction of the elevator track, causing it to fall into the clearance groove and get stuck in it, thereby preventing the elevator track from falling and improving the protective effect of the main ceiling 33. It also makes it easier for the construction personnel to push the elevator track back to the installation position, improving installation efficiency. Due to the width limitation of the shaft 11, the main frame 3 is usually narrow, and the construction platform as a whole needs to be lightweight. When the main frame 3 is subjected to external forces, it is prone to shaking, which may cause the main frame 3 to collide with the side wall of the shaft 11 and the equipment in the shaft 11. Preferably, the clearance groove is rectangular and corresponds to the elevator rail 14. Thus, during construction, when the main frame 3 shakes significantly, if the main top plate shakes towards the elevator rail 14, the clearance groove can prevent the main top plate from severely colliding and scraping with the guide rail, ensuring the flatness of the elevator rail. At the same time, it can also limit the main frame 3 to prevent serious displacement after shaking. A buffer layer made of flexible materials such as rubber can also be set in the clearance groove to further reduce the damage to the elevator rail 14 caused by collisions and scrapes.

[0030] Preferably, the main top plate includes two first top plates 335 and second top plates 336 distributed along the second direction Y and spliced ​​together. The first top plates 335 and second top plates 336 are symmetrically arranged, and each has a first groove 337 at the splicing point. The first grooves 337 are spliced ​​together to form three third through holes, which are rectangular. The first top plates 335 and second top plates 336 also have second grooves 338 at the splicing point, which are spliced ​​together to form two clearance grooves. The spliced ​​main top plate can be fine-tuned by adjusting the width of its splice joints, thereby ensuring that the main top plate can block falling objects in the shaft 11 and prevent them from injuring construction personnel, thus achieving a protective effect. At the same time, it can also improve the versatility of the structure and can be adapted to more sizes and types of steel wire ropes a and elevator tracks 14.

[0031] Preferably, the main frame 3 also includes protective tubes corresponding to the perforations. These protective tubes are sandwiched between the main bottom plate and the main top plate and are fitted over the wire rope a. The tubes can be made of fire-retardant materials such as plastic, thus protecting the wire rope a during welding operations and preventing damage from flying sparks. The protective tube can be a round tube, or preferably, it can be wound into a round tube shape, allowing for replacement without removing the wire rope a, facilitating easy disassembly and replacement.

[0032] The first auxiliary frame 4 includes a first auxiliary base frame and an auxiliary canopy mounted on the first auxiliary base frame, forming an auxiliary working space connected to the main working space. The first auxiliary base frame slides along the second direction Y with the main frame 3, and the auxiliary canopy moves with the first auxiliary base frame. The first auxiliary base frame includes a first sliding auxiliary rod 41 and a second sliding auxiliary rod 42. One end of each of the two first sliding auxiliary rods 41 is movably inserted into the first sliding main rod 311, and the other end is connected to the end of the first auxiliary rod connecting rod 43, respectively. A third base plate 44 is placed on and fixed to the first sliding auxiliary rods 41 and the first auxiliary rod connecting rod 43. The third base plate 44 is stacked on the bottom surface of the second base plate 313, providing support for the operators. One end of each of the two second sliding auxiliary rods 42 slides through the second sliding main rod 321, and the other end is connected to both ends of the second auxiliary rod connecting rod 45, respectively, and is connected to the first sliding auxiliary rod 41 through the auxiliary frame support rod. An entrance / exit for construction personnel is formed between the first sliding auxiliary rod 41 and the second sliding auxiliary rod 42. The middle part of the second sliding auxiliary rod 42 arches upwards away from the third base plate 44, thus forming a door-shaped structure that allows operators to pass through. The auxiliary canopy is covered on both sides of the top of the second sliding auxiliary rod 42 and fixedly connected to it. The auxiliary canopy includes a third top plate 46, connecting angle steel 47 disposed on the top surface of the third top plate 46 and corresponding to the second sliding auxiliary rod 42, and a reinforcing rod 48 spanning between the two connecting angle steels 47.

[0033] A connecting support frame 49 is provided on the first sliding auxiliary rod 41. Two connecting frames 5 are symmetrically arranged on both sides of the first auxiliary frame 4 at both ends of the connecting support frame 49. The connecting frames 5 correspond to the openings 15 of the shaft, allowing the construction personnel to enter the auxiliary working space and then the main working space via the connecting frames 5. There are two connecting frames 5, allowing the construction personnel to enter and exit the construction platform from the left side and work on the left shaft 11, or from the right side and work on the right shaft 11. This eliminates the need to distinguish the entry and exit directions of the construction platform during use, improving installation efficiency and ensuring the overall balance and stability of the construction platform structure. In this embodiment, as... Figure 1As shown, since the elevator structure has two shafts, a construction platform needs to be placed in each of the two shafts during the construction process, that is, two construction platforms are required. The construction platform in the left shaft enters and exits through the connecting frame 5 on its left side, while the construction platform in the right shaft enters and exits through the connecting frame 5 on its right side.

[0034] The connecting frame 5 includes a rectangular base frame 51, a second guardrail 52, a third guardrail 53, and a gate 54. A fourth base plate 55 is provided on the rectangular base frame 51. The second guardrail 52 and the third guardrail 53 are spaced apart on the rectangular base frame 51, forming a passage connecting to the entrance and exit. A limit block 56 is provided on the third guardrail 53. The gate 54 is rotatably mounted on the second guardrail 52, and the abutting end of the gate 54 is engaged with the limit block 56. Construction personnel can open and close the passage by rotating the gate 54, thereby improving safety.

[0035] Since only one connecting frame 5 is typically used for personnel access during construction, the other connecting frame 5 needs to be kept closed to ensure personnel safety. Preferably, the abutting end of the gate 54 has a first positioning hole 541, and the limiting block 56 has a second positioning hole 561 corresponding to the first positioning hole 541. When the abutting end of the gate 54 is engaged with the limiting block 56, the first positioning hole 541 and the second positioning hole 561 are coaxial. At this time, a positioning element can be inserted into the first positioning hole 541 and the second positioning hole 561. This positioning element can be a bolt or pin, or a cable tie or rope for securing the gate 54, thus preventing personnel from entering or exiting the construction platform through that connecting frame 5.

[0036] like Figure 9 As shown, the first auxiliary frame 4 also includes a slidably mounted locking rod 57. Each of the door rods 54 has a locking insertion hole 541 coaxial with the locking rod 57. This locking insertion hole 541 can be located on the same side as or opposite to the abutment end relative to the rotation axis. Preferably, the locking insertion hole 541 and the abutment end are located at opposite ends of the rotation axis, thus avoiding occupying auxiliary working space. When one end of the locking rod 57 slides out of the locking insertion hole 541 of one door rod 54, its other end inserts into the locking insertion hole 541 of the other door rod 54, thereby achieving a linkage function and ensuring the safety of construction personnel. The locking rod 57 can be slidably mounted on the second auxiliary frame connecting rod 45 or other structures to prevent slippage.

[0037] Preferably, the first auxiliary frame 4 can have two sets and be slidably arranged on the front and rear sides of the main frame 3 along the second direction Y. It can also include a second auxiliary frame 6. The first auxiliary frame 4 and the second auxiliary frame 6 are slidably arranged on the front and rear sides of the main frame 3 along the second direction Y. The combination of the first auxiliary frame 4 and the second auxiliary frame 6 can be selected according to the actual construction needs, thereby improving the versatility of the construction platform. An auxiliary support rod 61 is inserted through the second auxiliary frame 6. The auxiliary support rod 61 is fixedly set on the second auxiliary frame 6 by a U-shaped clamp 7. The connecting support frame 49 is fixedly set on the first sliding auxiliary rod 41 by a U-shaped clamp 7. A supporting angle steel 8 extending along the second direction Y is also provided. The supporting angle steel 8 is erected on the top of the auxiliary support rod 61 and the connecting support frame 49 and is detachably connected to them by screws.

[0038] This invention discloses a side-door access construction platform, which can be used for construction in elevator shafts with side-door access. Its telescopic frame structure allows it to adapt to shafts of various sizes, improving the platform's versatility. Furthermore, the platform enhances worker safety by incorporating a canopy to prevent falling objects and obstacle avoidance grooves corresponding to the elevator tracks.

In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "fixed," or "set in," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
