Description

Technical Field

[0001] This application relates to the field of elevator components, and more specifically, to a car structure for an elevator. Background Technology

[0002] As the core personnel and cargo carrying facility in a construction hoist system, the structural design of the construction hoist car (or cage) directly affects the equipment's safety, ease of use, and transportation and installation efficiency. In existing technology, the construction hoist car typically consists of three main parts: the side enclosure structure, the bottom support structure, and the top cover structure. The side enclosure structure mainly comprises several columns and metal panels welded or fixed to them, forming a closed or semi-closed side space. The bottom support structure includes a bottom frame beam and a bottom plate laid and welded to it. Similarly, the top cover structure uses welding or other methods to fix the cover plate to the top frame. These beams, columns, plates, and other components are permanently connected primarily through welding, thus forming a rigid, integral car body.

[0003] However, this traditional welded car structure has significant drawbacks. First, welding binds the side panels, bottom supports, and roof structure into a single, inseparable unit, fixing the car's volume and dimensions at the factory. This poses a major inconvenience for long-distance transportation, not only occupying considerable space and increasing transport costs but also making the car susceptible to deformation or damage during transit due to collisions. Second, if a section of the car (such as a side panel or part of the floor) is damaged, the welded connection makes local replacement and repair extremely difficult, often requiring cutting and re-welding of the entire structure. This not only increases repair costs but may also compromise the overall strength and safety of the structure. Summary of the Invention

[0004] In view of this, this application provides a car structure for an elevator to solve the technical problems of inconvenient disassembly, transportation and maintenance of the welded car structure in the prior art.

[0005] This application provides a car structure for an elevator, wherein the car structure for the elevator includes:

[0006] The system includes a bottom support structure, a side enclosure structure, and a top cover structure. The bottom support structure includes a bottom beam and a bottom plate detachably connected to the bottom beam. The side enclosure structure includes a side frame and a side plate detachably connected to the side frame. The top cover structure includes a top beam and a cover plate detachably connected to the top beam. The bottom end of the side frame is detachably connected to the bottom beam, and the cover plate is detachably connected to the top end of the side frame. The side enclosure structure has an entrance / exit.

[0007] A lifting beam is disposed above the top cover structure;

[0008] Two sliding doors are detachably connected to the outside of the side enclosure structure. The two sliding doors can slide laterally away from each other to open the entrance or slide laterally closer to each other to close the entrance.

[0009] Furthermore, the base plate is detachably connected to the base beam by threaded fasteners, the side plate is detachably connected to the side frame by threaded fasteners, the cover plate is detachably connected to the top beam by threaded fasteners, the bottom end of the side frame is detachably connected to the base beam by threaded fasteners, and the cover plate is detachably connected to the top end of the side frame by threaded fasteners.

[0010] Furthermore, the car structure for the elevator includes a transverse hanging rail, which is detachably connected to the outside of the side enclosure structure and located above the entrance / exit. The upper end of the sliding door is detachably connected to a hanging wheel, which is laterally slidably installed in the transverse hanging rail.

[0011] Furthermore, the side enclosure structure includes a first side enclosure, a second side enclosure, a third side enclosure, and a fourth side enclosure connected in sequence. The first side enclosure, the second side enclosure, the third side enclosure, and the fourth side enclosure enclose a quadrilateral space. Each of the first side enclosure, the second side enclosure, the third side enclosure, and the fourth side enclosure includes the side frame and the side plate. The entrance / exit is formed on the first side enclosure. The outer sides of the second side enclosure and the fourth side enclosure each have a vertically extending guide rail. The side of the guide rail opposite to the side enclosure structure has a vertically extending guide groove. The elevator corresponding to the car structure for the elevator includes a vertically extending limiting post. The limiting post cooperates with the guide groove to limit the movement of the car structure, so that when the car structure moves up and down, the guide groove moves up and down along the limiting post.

[0012] Furthermore, the car structure for the elevator includes a sliding door safety emergency structure, which can cooperate with the two sliding doors to generate an intervention force when the two sliding doors slide laterally away from each other, and the intervention force can cause the sliding doors to slide laterally closer to each other.

[0013] Furthermore, the sliding door safety emergency structure includes a lateral limiting rail and two drive beams that are laterally slidably limited within the lateral limiting rail. Each of the two drive beams corresponds to one of the two sliding doors. An elastic element connects the drive beams to the lateral limiting rail. The lateral limiting rail is connected to the inner side of the first side enclosure and located above the entrance / exit. The sliding door safety emergency structure includes a safety emergency triggering mechanism movably disposed on the inner side of each sliding door. The safety emergency triggering mechanism can be selectively in a first state and a second state. In the first state… The safety emergency triggering mechanism on the inner side of each sliding door is limited to the corresponding drive beam, so as to drive the two drive beams to slide laterally away from each other on the lateral limit rail when the two sliding doors slide laterally away from each other. When the two drive beams slide laterally away from each other on the lateral limit rail, the corresponding elastic element can form an elastic force on the drive beam, so as to make the two drive beams slide laterally closer to each other on the lateral limit rail, so as to generate the intervention force on the two sliding doors. In the second state, the safety emergency triggering mechanism on the inner side of each sliding door is released from the limited cooperation with the corresponding drive beam.

[0014] Furthermore, the sliding door safety emergency structure includes connecting rods connected to each drive beam, with a pin on the connecting rod. The sliding door safety emergency structure includes insertion holes on the bottom surface of guide grooves that extend from the inner surfaces of the second and fourth side walls to the corresponding guide rails. The limiting post faces the insertion holes to form a row of vertically arranged limiting blind holes. When the safety emergency triggering mechanism is in the first state and the struggle force of the two sliding doors that close the entrance / exit moving away from each other is greater than the intervention force, the drive beam moves along the transverse limiting rail against the elastic force of the corresponding elastic element so that the pin passes through the corresponding insertion hole and is inserted into the limiting blind hole of the corresponding limiting post.

[0015] Furthermore, the upper surface of the end of the pin forms a pointed tip that gradually narrows toward the corresponding limiting post.

[0016] Furthermore, an ear plate is provided on the inner side of the sliding door, and a vertical hole is formed on the ear plate. The safety emergency triggering mechanism includes a trigger rod that can be raised and lowered through the vertical hole in the ear plate of the corresponding sliding door. A protruding ring is formed on the trigger rod, and a limiting plate is provided at the upper end of the trigger rod. A limiting groove is formed on the drive beam. In the first state, the limiting plate is limited in the limiting groove. In the second state, the limiting plate is disengaged from the limiting groove, and the protruding ring is supported on the ear plate of the corresponding sliding door.

[0017] Furthermore, a limit block is provided at the upper end of the trigger rod, and the limit plate is provided below the limit block. In the first state, the limit block is at a first angle, and in the second state, the limit block is at a second angle and is limited between the transverse limit rail and the corresponding sliding door. The first angle and the second angle are 90° apart.

[0018] The beneficial effects of the elevator car structure provided by this invention are as follows:

[0019] Compared to existing technologies, the car structure for elevators provided by this invention features a detachable connection between the bottom support structure, side enclosure structure, and top cover structure. Furthermore, the bottom beam and bottom plate, side frame and side plate, and top beam and cover plate within the bottom support structure, side enclosure structure, and top cover structure are also detachably connected. Therefore, compared to traditional welded car structures, the car structure provided by this invention significantly improves detachability, transportation convenience, and maintenance ease, overcoming the drawbacks of welding components in traditional welded car structures. This allows for convenient and rapid assembly and disassembly, adapting to efficient and flexible construction, assembly, and transportation requirements.

[0040] See Figures 1 to 12 This application provides a car structure for an elevator, wherein the car structure for the elevator includes:

[0041] The bottom support structure 100, the side enclosure structure 200, and the top cover structure 300 are provided. The bottom support structure 100 includes a bottom beam 101 and a bottom plate 102 detachably connected to the bottom beam 101. The side enclosure structure 200 includes a side frame 201 and a side plate 202 detachably connected to the side frame 201. The top cover structure 300 includes a top beam 301 and a cover plate 302 detachably connected to the top beam 301. The bottom end of the side frame 201 is detachably connected to the bottom beam 101, and the cover plate 302 is detachably connected to the top end of the side frame 201. The side enclosure structure 200 has an entrance 203.

[0042] The lifting beam 1 is installed above the top cover structure 300. The lifting beam 1 is used to connect the lifting hook and other lifting devices of the elevator. Specifically, the lifting beam 1 can also be detachably connected to the top cover structure 300.

[0043] Two sliding doors 2 are detachably connected to the outside of the side enclosure structure 200. The two sliding doors 2 can slide laterally away from each other to open the entrance 203 or slide laterally close to each other to close the entrance 203.

[0044] Because the bottom support structure 100, side enclosure structure 200 and top cover structure 300 in the car structure for the elevator provided by the present invention are connected by a detachable connection, and the bottom beam 101 and bottom plate 102, the side frame 201 and side plate 202, and the top beam 301 and cover plate 302 in the bottom support structure 100, side enclosure structure 200 and top cover structure 300 are also connected by a detachable connection, the car structure provided by the present invention has significantly improved in terms of detachability, transportation convenience and maintenance convenience compared with the traditional welded car structure. It overcomes the disadvantages of welding the components in the traditional welded car structure, thereby enabling convenient and quick disassembly and assembly to meet the requirements of efficient and flexible construction assembly and transportation.

[0045] According to a specific embodiment of this application, the base plate 102 is detachably connected to the base beam 101 by threaded fasteners, the side plate 202 is detachably connected to the side frame 201 by threaded fasteners, the cover plate 302 is detachably connected to the top beam 301 by threaded fasteners, the bottom end of the side frame 201 is detachably connected to the base beam 101 by threaded fasteners, and the cover plate 302 is detachably connected to the top end of the side frame 201 by threaded fasteners. The threaded fasteners specifically include assemblies formed by bolts and nuts. The corresponding connecting parts (base beam 101, base plate 102, side frame 201, side plate 202, top beam 301 and cover plate 302) should be provided with mounting holes 3 for bolts to pass through.

[0046] According to one embodiment of this application, the car structure for the elevator includes a transverse hanging rail 4, which is detachably connected to the outside of the side enclosure structure 200 and located above the entrance / exit 203. The upper end of the sliding door 2 is detachably connected to a hanging wheel 5, which is laterally slidably installed in the transverse hanging rail 4. Specifically, the upper end of the sliding door 2 is detachably connected to a threaded rod 6, and the hanging wheel 5 is connected to the upper end of the threaded rod 6.

[0047] According to a specific embodiment of this application, the side enclosure structure 200 includes a first side enclosure 204, a second side enclosure 205, a third side enclosure 206, and a fourth side enclosure 207 connected in sequence. The first side enclosure 204, the second side enclosure 205, the third side enclosure 206, and the fourth side enclosure 207 enclose a quadrilateral space. Each of the first side enclosure 204, the second side enclosure 205, the third side enclosure 206, and the fourth side enclosure 207 includes a side frame 201 and a side panel 202. An entrance 203 is formed on the first side enclosure 204, and the second side enclosure 205 and the fourth side enclosure 207 are connected in sequence. Each of the 7 has a guide rail 400 extending vertically on its outer side. The guide rail 400 has a guide groove 401 extending vertically on the side away from the side enclosure structure 200. The elevator corresponding to the car structure of the elevator includes a limiting post 500 extending vertically. The limiting post 500 and the guide groove 401 are matched for limiting, so that when the car structure moves up and down, the guide groove 401 moves up and down along the limiting post 500. The height of the limiting post 500 should cover the highest and lowest positions during the car structure's up and down movement, so that it can be limited and guided throughout the entire up and down movement of the car structure.

[0048] According to one embodiment of this application, the car structure for the elevator includes a sliding door safety emergency structure. The sliding door safety emergency structure can cooperate with two sliding doors 2 to generate an intervention force when the two sliding doors 2 slide laterally away from each other. The intervention force can cause the sliding doors 2 to slide laterally closer to each other. It is understood that before the car structure moves up and down, the two sliding doors 2 are locked and fixed at the closed entrance / exit 203 by a known door lock (not shown). When the door lock fails unexpectedly and causes the sliding doors 2 to open unexpectedly, and when the struggle force of the sliding doors 2 when they move away from each other is less than the intervention force, the sliding door safety emergency structure can cause the sliding doors 2 to slide laterally closer to each other, thereby effectively preventing the sliding doors 2 from opening unexpectedly.

[0049] According to a specific embodiment of this application, the sliding door safety emergency structure includes a lateral limiting rail 7 and two drive beams 600 that are laterally slidably limited within the lateral limiting rail 7. Each of the two drive beams 600 corresponds to one of the two sliding doors 2. An elastic element 8 (e.g., a spring) connects the drive beams 600 to the lateral limiting rail 7. The lateral limiting rail 7 is connected to the inner side of the first side perimeter 204 and located above the entrance / exit 203. The sliding door safety emergency structure includes a safety emergency triggering mechanism movably disposed on the inner side of each sliding door 2. The safety emergency triggering mechanism can be selectively in a first state and a second state. It should be noted that this application… Figures 6 to 9In each figure, one of the safety emergency triggering mechanisms in the car structure of the elevator is in a first state, and the other safety emergency triggering mechanism is in a second state. In the first state, the safety emergency triggering mechanism on the inner side of each sliding door 2 is in a limiting engagement with the corresponding drive beam 600, so as to drive the two drive beams 600 to slide laterally away from each other on the lateral limiting rail 7 when the two sliding doors 2 slide laterally away from each other. When the two drive beams 600 slide laterally away from each other on the lateral limiting rail 7, the corresponding elastic element 8 can form an elastic force on the drive beam 600 that causes the two drive beams 600 to slide laterally closer to each other on the lateral limiting rail 7, so as to generate an intervention force on the two sliding doors 2. Before the car structure performs the lifting movement, the safety emergency triggering mechanism is first adjusted to the first state. In the second state, the safety emergency triggering mechanism on the inner side of each sliding door 2 is released from the limiting engagement with the corresponding drive beam 600.

[0050] According to one embodiment of this application, the sliding door safety emergency structure includes a connecting rod 9 (specifically an L-shaped rod) connected to each drive beam 600. A pin 10 is provided on the connecting rod 9. The sliding door safety emergency structure includes an insertion hole 11 extending from the inner surface of the second side panel 205 and the fourth side panel 207 through the bottom surface of the guide groove 401 of the corresponding guide rail 400. A row of vertically arranged limit blind holes 501 are formed on the limit post 500 facing the insertion hole 11. When the safety emergency triggering mechanism is in the first state and the struggle force of the two sliding doors 2 of the closed entrance / exit 203 moving away from each other is greater than the intervention force, the drive beam 600 moves along the transverse limit rail 7 against the elastic force of the corresponding elastic element 8, causing the pin 10 to pass through the corresponding insertion hole 11 and insert into the limit blind hole 501 of the corresponding limit post 500. This stops the moving car structure, thus reminding the personnel in the car structure to close the sliding door 2 completely to prevent... If personnel or goods on the car structure accidentally fall from the entrance / exit 203, the lifting and lowering movement of the car structure is relatively slow. Therefore, the jamming impact force generated by the pin 10 passing through the corresponding socket 11 and inserting into the limiting blind hole 501 of the corresponding limiting post 500 on the car structure is within an acceptable range. After the personnel on the car structure close the sliding door 2, when the two sliding doors 2 move closer to each other to close the entrance / exit 203, the pin 10 retracts from the corresponding socket 11 as the sliding door 2 moves. At this time, the car structure can continue to resume normal lifting and lowering movement. In addition, when the pin 10 passes through the corresponding socket 11 and inserts into the limiting blind hole 501 of the corresponding limiting post 500 and abuts against the bottom of the limiting blind hole 501, it cannot continue to move. At this time, the sliding door 2 also cannot continue to move. This ensures that when the two sliding doors 2 are accidentally opened, the opening gap will not be too large, further effectively preventing personnel or goods on the car structure from accidentally falling from the entrance / exit 203.

[0051] According to a preferred embodiment of this application, the upper surface of the end of the pin 10 forms a pointed head that gradually narrows toward the corresponding limiting post 500. The pointed head helps the pin 10 to be inserted more quickly into the limiting blind hole 501 of the corresponding limiting post 500 during the lifting and lowering movement of the car structure.

[0052] According to one embodiment of this application, an ear plate 12 is provided on the inner side of the sliding door 2, and a vertical hole is formed on the ear plate 12. The safety emergency triggering mechanism includes a trigger rod 13 that is vertically and retractably passed through the vertical hole on the ear plate 12 of the corresponding sliding door 2. A protruding ring 14 is formed on the trigger rod 13, and a limiting plate 15 is provided at the upper end of the trigger rod 13. A limiting groove 601 is formed on the drive beam 600. In a first state, the limiting plate 15 is limited in the limiting groove 601. In a second state, the limiting plate 15 is disengaged from the limiting groove 601, and the protruding ring 14 is supported on the ear plate 12 of the corresponding sliding door 2.

[0053] According to a specific embodiment of this application, a limiting block 16 is provided at the upper end of the trigger rod 13, and a limiting plate 15 is provided below the limiting block 16. In a first state, the limiting block 16 is at a first angle. In a second state, the limiting block 16 is at a second angle and is limited between the transverse limiting rail 7 and the corresponding sliding door 2. The first angle and the second angle are 90° apart. When the safety emergency triggering mechanism is in the second state, the trigger rod 13 is manually lifted so that the limiting plate 15 is first higher than the drive beam 600. Then the trigger rod 13 is rotated 90° so that the limiting plate 15 is directly above the limiting groove 601. Then the trigger rod 13 is lowered so that the limiting plate 15 falls into and is limited in the corresponding limiting groove 601.

[0054] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
