Description

Technical Field

[0001] The present invention relates to the technical field of elevator cars, and in particular to an elevator car and an installation method thereof. Background Art

[0002] The elevator car is a box-shaped space structure used by elevators to carry and transport people and goods. It is generally composed of main components such as the car bottom, car walls, and car top, and is mostly made of metal materials. Its function is to transport people or goods. It is an important component equipment in modern high-rise buildings. Elevator cars are customized and produced in factories and then transported to the construction site for splicing and assembly.

[0003] However, the existing elevator car bottom, car wall and car roof are all fixed with bolts. In some small cars, reinforced car walls are used to avoid the connection between the car walls, but the car walls and the bottom and car roof still need to be manually connected, which makes the elevator installation time-consuming and difficult.

[0004] In addition, the above-mentioned installation method requires the cooperation of two or more construction workers to complete. One person straightens the car wall inside the car, and the other personnel fix the bolts outside the car. On the one hand, this method has low installation efficiency, high labor intensity and high labor cost for construction workers. On the other hand, in some scenes where the elevator shaft is narrow, fixing the bolts on the outside is time-consuming and labor-intensive, the operation is extremely awkward, and workers are at risk of falling and getting injured outside the car. Summary of the invention

[0005] 1. Technical issues to be resolved

[0016] Preferably, the rib plate and the extension plate are both provided with connection holes for assembly, and the rib plate and the extension plate are both provided with connection parts that cooperate with the connection holes for assembly.

[0017] Preferably, the connecting component includes a fixing frame, a connecting rod, a propulsion spring and a baffle rod. The fixing frame is movably mounted with the rib plate and the extension plate. The connecting rod is movably mounted with the fixing frame and the connecting hole respectively. The outer surface of the connecting rod is mounted with a propulsion spring.

[0022] The present invention also provides an elevator car installation method, comprising the following steps:

[0023] S1. First, put the bottom plate onto the lifting frame through the door opening of the elevator shaft, and then fix the bottom plate and the lifting frame together;

[0024] S2, then the worker stands on the bottom plate, uses a handheld suction cup to fix the door panel, side panel and back panel, and places them on the plug-in components on the side of the bottom plate respectively, and presses down the door panel, side panel and back panel to connect the plug-in components with the plug-in holes at the bottom of the door panel, side panel and back panel;

[0025] S3.

[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention provides an elevator car and an installation method, which have the following beneficial effects:

[0028] 1. By setting up the plug-in mechanism and the trigger mechanism, the bottom plate is first connected to the elevator lifting frame during installation, and then the worker stands on the bottom plate, uses a handheld suction cup to carry the back plate, door plate and side plate, and places them on the plug-in components on the side of the bottom plate respectively, and then presses down. After the back plate, door plate and side plate are subjected to force, they press the trigger mechanism downward, so that the trigger mechanism releases the restriction on the plug-in mechanism. The strong spring in the plug-in mechanism pushes the plug-in rod out and snaps into the plug-in hole, so that the back plate, door plate and side plate are snap-fitted and fixed;

[0029] After the back panel, door panel and side panels are all installed, the top panel is buckled on the top of the back panel, door panel and side panels, and the plug-in mechanism on the side of the top panel is used to align with the plug-in holes on the top of the back panel, door panel and side panels. Then the top panel is pressed down to make the trigger mechanism release the restriction on the plug-in mechanism. The plug-in mechanism uses the plug-in holes to fix the back panel, door panel and side panels, eliminating the need for tedious bolt tightening operations. Workers can complete the installation of the car wall only in the car, avoiding the low efficiency and high risk of workers fixing the installation outside the car.

[0030] 2. By setting a hook-type frame and a connecting rod, the door panel, back panel and side panel can be directly and vertically plugged into the hook-type frame, and the hook-type frame can be used to support and position the door panel, back panel and side panel, while the connecting rod can be plugged into the connecting holes on the door panel, back panel and side panel by the thrust of a strong spring, so as to limit the position of the door panel, back panel and side panel, and the connecting rod is inclined and has a conical front end, so that it applies an oblique downward thrust to the connecting hole, so that the door panel, back panel and side panel can always fit tightly with the sides of the bottom panel and the top panel, so as to prevent the deformation and loosening of the connection between the hook-type frame and the door panel, back panel and side panel after long-term use of the car.

[0031] 3. By setting a locking mechanism, the locking mechanism utilizes the sliding cooperation between the C-shaped rod and the movable groove to clamp and support the bottom of the pressure plate. When the C-shaped rod is not triggered, the pressure plate is in a locked state. At this time, the pressure plate cannot move downward, and thus cannot drive the baffle to separate from the plug-in rod. Only after the door panel, back panel and side panel are placed on the pressure plate, the spring piece extends into the movable groove to squeeze the C-shaped rod to trigger it, and the pressure plate is unlocked. This method can prevent the pressure plate from being accidentally triggered during transportation or installation, resulting in the accidental release of the plug-in rod, causing the problem of being unable to install.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Example 1

[0054] See also Figure 1-12 , an elevator car and installation method, comprising a bottom plate 1, a door plate 2, a top plate 3, a side plate 4 and a back plate 5, the upper and lower ends of the door plate 2, the back plate 5 and the side plate 4 are all provided with plug-in holes 8, and the bottom plate 1 and the top plate 3 are both provided with plug-in components 6 for cooperating with the plug-in holes 8 to position and install the door plate 2, the side plate 4 and the back plate 5;

[0055] By setting the plug-in component 6, the plug-in component 6 can carry and place the door panel 2, the back panel 5 and the side panel 4, and use the plug-in hole 8 to apply a continuous fixing force to the door panel 2, the back panel 5 and the side panel 4, so that the three can be tightly connected with the bottom panel 1 and the top panel 3, and automatically compensate for the deformation gap caused by long-term use. It should be further explained that in this embodiment, the door panel 2, the back panel 5 and the side panel 4 are all reinforced and thickened, and can rely on their own strength to support the top panel 3 after splicing.

[0056] like Figure 6 As shown, the plug-in component 6 includes a hook-shaped frame 601, a plug-in mechanism 602 and a trigger mechanism 603. The hook-shaped frame 601 is arranged on the side of the bottom plate 1 and the top plate 3, the plug-in mechanism 602 is arranged on the side of the hook-shaped frame 601, and the position is aligned with the plug-in hole 8, the trigger mechanism 603 is arranged in the hook-shaped frame 601, and is in contact with the end surface of the plug-in mechanism 602, and a slot is opened in the hook-shaped frame 601 for the plug-in mechanism 602 and the trigger mechanism 603 to slide inside it;

[0057] The hook-type frame 601 can be used to clamp and support the door panel 2, back panel 5 and side panel 4, so that the three can be stably placed on the sides of the bottom plate 1 and the top plate 3, and ensure the vertical stability of the three with the bottom plate 1 and the top plate 3 respectively. The plug-in mechanism 602 inside the hook-type frame 601 will release the stored elastic force after being triggered, and plug into the plug-in holes 8 on the door panel 2, back panel 5 and side panel 4 to fix the door panel 2, back panel 5 and side panel 4 to the bottom plate 1 and the top plate 3 respectively, avoiding the cumbersome manual bolt tightening operation and simplifying the installation process and work.

[0058] like Figure 7 As shown, the plug-in mechanism 602 includes a support frame 6021 disposed on the side of the hook-shaped frame 601, a plug-in rod 6022 slidably matched with the support frame 6021, and a strong spring 6023 connected between the plug-in rod 6022 and the support frame 6021. The support frame 6021 and the plug-in rod 6022 are both tilted downward, the front end of the plug-in rod 6022 is conical, and the tail end of the plug-in rod 6022 is provided with a pull ring 6024;

[0059] By setting a strong spring 6023 and a plug rod 6022, in the factory or before pre-installation, the plug rod 6022 is pulled outward by a stretching device through the pull ring 6024, so that the strong spring 6023 connected to the plug rod 6022 is in a potential energy compression state, and then after the door panel 2, the back panel 5 and the side panel 4 are installed, a part of the elastic potential energy of the strong spring 6023 is released, and the plug rod 6022 is inserted into the plug hole 8, and the remaining elastic potential energy of the strong spring 6023 is used to apply a continuous elastic force to the plug rod 6022, and the plug rod 6022 uses a conical setting to apply a continuous thrust to the door panel 2, the back panel 5 and the side panel 4 through the plug hole 8. When a gap appears in the car after long-term use, the gap can be compensated by releasing the remaining elastic potential energy of the strong spring 6023 to ensure the stability and reliability of the car.

[0060] It should be further explained that when the car is repaired or disassembled, a stretching device can be used to drive the plug-in rod 6022 to move out of the plug-in hole 8 through the pull ring 6024 and enter a potential energy compression state, so that the car has a disassembly and repair path.

[0061] like Figure 7 As shown, the trigger mechanism 603 includes a baffle 6031 that slides up and down with the hook frame 601, the baffle 6031 is in contact with the front end of the plug rod 6022, and a pressure plate 6032 that moves synchronously with the baffle 6031 is provided in the hook frame 601, and a stabilizing spring 6033 connected to the inner bottom surface of the hook frame 601 is provided on the bottom surface of the pressure plate 6032;

[0062] The baffle plate 6031 can be used to block the end surface of the plug rod 6022, so that the plug rod 6022 can be kept in a potential energy compression state by the strong spring 6023. When the baffle plate 6031 restricts the plug rod 6022, it will be subjected to the thrust force exerted on the plug rod 6022 by the strong spring 6023. The baffle plate 6031 is attached to the outer side of the hook frame 601 to exert the thrust force on the hook frame 601, so that it can stably support the plug rod 6022. The pressure plate 6032 located in the hook frame 601 is connected to the baffle plate 6031 so that it can synchronously drive the baffle plate 6031 to move downward after being subjected to the downward pressure, so that it is separated from the plug rod 6022, so that the plug rod 6022 can be automatically released and connected to the plug hole 8 after the door panel 2, the back panel 5 and the side panel 4 are installed.

[0063] It should also be further explained that the stabilizing spring 6033 under the pressure plate 6032 applies an upward thrust thereto, so that the pressure plate 6032 can only be triggered by the cooperation of the aligned installation of the door panel 2, the side panel 4 and the back panel 5 and the downward pressure force applied manually, which can prevent foreign objects from falling onto the pressure plate 6032, eliminate the accidental release of the plug-in rod 6022, and ensure the stability of the installation process.

[0064] like Figure 7 As shown, a locking mechanism 604 for fixing the position of the pressing plate 6032 is provided in the specific hook-shaped frame 601, and the outer sides of the door panel 2, the side panel 4 and the back panel 5 are all provided with spring pieces 12 acting on the locking mechanism 604;

[0065] like Fig.11 As shown, the locking mechanism 604 includes a movable groove 6043 provided in the hook frame 601, a C-shaped rod 6041 for locking the pressure plate 6032 is movably provided in the movable groove 6043, the C-shaped rod 6041 is triggered and cooperated with the spring 12, a support spring 6042 is provided on the inner side of the C-shaped rod 6041, and the other end of the support spring 6042 is connected to the inner cavity of the movable groove 6043;

[0066] In this embodiment, the C-shaped frame is used to support and limit the pressure plate 6032. The lower bend of the C-shaped frame is located under the pressure plate 6032, supporting the pressure plate 6032 so that it cannot move downward, and thus cannot drive the baffle 6031 to release the plug-in rod 6022. The upper bend of the C-shaped rod 6041 is above the pressure plate 6032 and retracts into the movable groove 6043. In this way, foreign objects falling onto the pressure plate 6032 can be prevented from triggering it, thereby providing insurance for the pressure plate 6032. When the door panel 2, the back panel 5 and the side panel 4 are installed, the spring sheet 12 on the side thereof will use its own elasticity to extend into the movable groove 6043, and then push the C-shaped rod 6041 to release the restriction on the pressure plate 6032. The cooperation between the C-shaped rod 6041 and the spring sheet 12 can ensure that the plug-in mechanism 602 can be triggered only when the door panel 2, the back panel 5 and the side panel 4 are installed, thereby ensuring the stability of the plug-in mechanism 602 before transportation, storage and installation.

[0067] Example 2

[0068] like Figure 3-5 As shown, ribs 10 are provided at both ends of the outer surfaces of the door panel 2, the side panel 4 and the back panel 5, and extension plates 11 for connecting the ribs 10 on the side panel 4 are provided on the door panel 2 and the back panel 5, and connecting holes 9 for assembly are provided on the ribs 10 and the extension plates 11, and connecting parts 7 are provided on the ribs 10 and the extension plates 11 to fit the connecting holes 9 for splicing the two.

[0069] In some large-sized and lightweight cars, overly thick door panels 2, back panels 5 and side panels 4 will make the overall weight of the elevator heavier, thereby reducing the load-bearing capacity of the car. In this embodiment, the door panels 2, back panels 5 and side panels 4 of the car are designed to be thin and light to achieve the effect of reducing the weight of the car. Then, the outer sides of the door panels 2, back panels 5 and side panels 4 are supported by ribs 10 to increase their vertical load-bearing and horizontal anti-deformation strength. At the same time, extension panels 11 are provided at both ends of the door panels 2 and back panels 5 to wrap and fit the two ends of the side panels 4, so as to ensure that the stable support strength and anti-deformation strength can be maintained after the thickness of the car is reduced.

[0070] In addition, it should be further explained that the rib plate 10 and the extension plate 11 can be formed by integral stamping and welding according to the specific material. The rib plate 10 is provided on the outer side of the door plate 2, the back plate 5 and the side plate 4 as a general form of this embodiment, and the extension plates 11 are provided at both ends of the door plate 2 and the back plate 5 as an implementation method of this embodiment. The setting position of the extension plate 11 should be determined according to the installation sequence of the door plate 2, the back plate 5 and the side plate 4, that is, the car wall provided with the extension plate 11 is installed first, and the car wall without the extension plate 11 is installed last. It should be explained that the car wall includes the door plate 2, the side plate 4 and the back plate 5;

[0071] In addition, the connecting member 7 in this embodiment is of a universal type and can be used to connect any two car walls. At the same time, the number of the connecting member 7 and the connecting hole 9 can be set accordingly according to the different car sizes. In addition, it should be further explained that the connecting member 7 needs to be fixed on the car wall where it is installed first. Figure 8 The middle connecting component 7 is in a state of being pre-installed with the car wall, and the plug-in rod 6022 is extended into half of the length of the fixing frame 701 to complete its connection with the car wall to be installed first. The remaining part of the fixing frame 701 is used to install the next car wall that fits the car wall to be installed first.

[0072] like Figure 8 As shown, the connecting component 7 includes a fixing frame 701, a connecting rod 702, a propulsion spring 703 and a blocking rod 705. The fixing frame 701 is movably mounted with the rib plate 10 and the extension plate 11. The connecting rod 702 is movably mounted with the fixing frame 701 and the connecting hole 9 respectively. The outer surface of the connecting rod 702 is mounted with a propulsion spring 703. One end of the outer side of the propulsion spring 703 is fixedly connected to the outer end of the connecting rod 702. The other end of the propulsion spring 703 is fixedly connected to the outer side surface of the fixing frame 701. The blocking rod 705 is slidably arranged in the fixing frame 701, and the side surface is in contact with the end of the connecting rod 702.

[0073] By setting the blocking rod 705 and the connecting rod 702, the blocking rod 705 plays a limiting role on the connecting rod 702, so that the connecting rod 702 extends the propulsion spring 703 and puts the connecting rod 702 in an energy storage state. When the door panel 2, the back panel 5 and the side panel 4 on the other side are installed, the ribs 10 on the outside will squeeze the blocking rod 705, so that the blocking rod 705 retracts into the fixing frame 701 and disengages from the connecting rod 702. When aligned with the connecting hole 9, the connecting rod 702 releases the elastic force of the propulsion spring 703, is inserted into the connecting hole 9, and connects the two adjacent door panels 2, the back panel 5 and the side panel 4, ensuring that after the thickness is reduced, it can effectively maintain stability and reliability.

[0074] Example 3

[0075] like Fig. 9 As shown, an anti-slip mechanism 706 for locking the connection rod 702 is disposed on the outside of the fixing frame 701, and a slot 704 is provided on the connection rod 702 to fit with the anti-slip mechanism 706, and the anti-slip mechanism 706 locks the connection rod 702 through the slot 704;

[0076] The anti-slip mechanism 706 includes a slide rail 7062 connected to the outer surface of the fixing frame 701, a wedge block 7061 is provided in the slide rail 7062 to cooperate with the card slot 704 to provide a position lock for the connecting rod 702, and a support plate 7063 is also hingedly provided on the outer surface of the fixing frame 701 to provide a limit for the wedge block 7061;

[0077] By setting the card slot 704 and the wedge block 7061, when the connecting rod 702 is inserted into the connecting hole 9, the connecting rod 702 will squeeze the support plate 7063 to separate the support plate 7063 from the wedge block 7061. The wedge block 7061 then moves downward under the action of gravity and is inserted into the card slot 704, so that the connecting rod 702 is connected to the rib 10 on the other side by using the wedge block 7061.

[0078] like Fig.12 As shown, the outer surface of the fixing frame 701 is provided with a fixed tooth 7066, and the wedge block 7061 is provided with a movable tooth 7064 that cooperates with the fixed tooth to allow the wedge block 7061 to move in one direction;

[0079] By setting the movable teeth 7064 and the fixed teeth 7066, the fixed teeth 7066 are arranged on the side of the fixed frame 701, with the oblique teeth facing upward and the flat teeth facing downward, and the movable teeth 7064 are arranged on the wedge block 7061, with the oblique teeth facing downward and the flat teeth facing upward, and can only move and rotate upward. With such a design, when the wedge block 7061 moves downward, the movable teeth 7064 will rotate upward with the support of the fixed teeth 7066 to avoid the fixed teeth 7066. When the wedge block 7061 moves upward, the movable teeth 7064 will rotate upward with the support of the fixed teeth 7066. When moving, the flat tooth surface of the movable tooth 7064 fits with the flat tooth surface of the fixed tooth 7066, so that the movable tooth 7064 is subjected to a downward rotation force, but under the support of the wedge block 7061, the movable tooth 7064 cannot rotate downward, so that the movable tooth 7064 is engaged with the fixed tooth 7066, and the wedge block 7061 cannot move upward, avoiding the problem of the wedge block 7061 being separated from the slot 704 due to vibration and other problems, further ensuring the firmness and stability of the connection of the connecting rod 702.

[0080] like Fig.12 As shown, a limit rod 7065 is slidably inserted in the wedge block 7061, and the limit rod is supported on the bottom surface of the movable tooth 7064;

[0081] The present solution also provides a further support method for the movable tooth 7064, using a limit rod 7065 to support the bottom of the movable tooth 7064 so that it will not rotate downward, and the limit rod 7065 is connected with the wedge block 7061 so that it can be freely pulled out. After the limit rod 7065 is pulled out, the movable tooth 7064 loses support and can rotate downward, releasing the restriction on the wedge block 7061, so that the wedge block 7061 can move upward, which is convenient for subsequent maintenance and disassembly.
