Description

Technical Field

[0001] This utility model relates to the field of elevator car movement and tilting technology, and in particular to an elevator car movement and tilting device. Background Technology

[0002] The elevator car is the core component of an elevator system, carrying passengers or goods. It mainly consists of a car frame, car body, door system, safety devices, and other structural elements. The production and processing of elevator cars includes processes such as material preparation, welding, bending, assembly, inspection, and testing. For ease of operation, the structural welding, component installation, and inspection processes require the elevator car to be tilted. Currently, this tilting is primarily done manually or with the assistance of an electric hoist. This method is complex, inefficient, and physically demanding, and it also easily causes bumps and scratches to the car's surface during tilting.

[0003] There are some existing studies related to elevator car tilting, such as the Chinese invention patent with application number CN201710371413.4, entitled "An Elevator Car Top Tilting Machine." This invention uses a brake-driven geared motor and a rotary cylinder. The active side has a brake-driven geared motor to drive the workpiece tilting, while the passive side has a rotary cylinder that effectively ensures the workpiece remains stable and undisturbed during tilting and operation, significantly reducing worker fatigue. It allows for double-sided assembly, stops at any angle, and is highly operable. However, it tilts the elevator car top panel, not the entire elevator car, and is only applicable to the processing of the elevator car top panel.

[0004] For example, Chinese utility model patent application number CN201520289609.5, entitled "A Tilting Device for Elevator Car Upper Beam Assembly," fixes the car upper beam to a rotatable tilting bracket, allowing it to rotate arbitrarily within the range of 0° to 180°. A 90° clockwise rotation pre-tightens the fixing bolts of the car top wheel mounting base. Operation is convenient, and pre-tightening the fixing bolts only requires activating the displacement mechanism, reducing the labor intensity of operators and improving assembly efficiency. However, it only tilts the car upper beam and cannot tilt the entire elevator car; it is only applicable to the processing of the car upper beam. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an elevator car moving and tilting device, which can move and tilt the entire elevator car. It is simple to operate, labor-saving and safe to tilt, which can greatly reduce the labor intensity of workers, improve work efficiency and ensure product quality.

[0006] This utility model is achieved using the following technical solution: an elevator car moving and tilting device, comprising a tilting component, a support frame, and a shifting component. There are two or three shifting components, each fixed to the support frame. One shifting component is fixed to the bottom end of the support frame, and the remaining shifting components are fixed to the sides of the support frame. The support frame is fixed to the drive end of the tilting component. The tilting component is used to tilt the support frame and the shifting components on it. The upper part of the support frame is open, allowing the car to be placed onto the support frame from the open portion. When the car is placed on the support frame, it can be moved using the shifting component located at the bottom end of the support frame. When the tilting of the support frame ends, it can be moved using the shifting component originally located at the side end of the support frame.

[0007] Furthermore, the flipping assembly includes a main flipping structure, which comprises a base frame, a flipping motor, a chain guide rail, and a bent plate. The flipping motor is fixed to the central crossbar of the base frame via a flipping motor bracket. A flipping sprocket is fixed to the shaft of the flipping motor. Two support sprocket brackets are symmetrically fixed on both sides of the flipping sprocket on the central crossbar of the base frame. Each support sprocket bracket rotatably mounts a support sprocket. The chain guide rail is fixed to the bottom end of the bent plate. The bent plate is semi-circular. The chain guide rail, flipping sprocket, and support sprockets cooperate for transmission. The flipping motor drives the flipping sprocket to rotate, which in turn drives the bent plate to rotate via the chain guide rail. During this process, the support sprockets on both sides cooperate with the chain guide rail to support the bent plate.

[0008] Furthermore, the flipping assembly also includes an auxiliary support structure, which is disposed on both sides of the main flipping structure and works in conjunction with it to provide auxiliary support to the support frame, thereby ensuring the stability of the support frame.

[0009] Furthermore, the auxiliary support structure includes a first support roller bracket, a first support roller, a second support roller bracket, a second support roller, and an auxiliary support plate. Four first support roller brackets are symmetrically fixed at the ends of the bottom frame, and a first support roller is rotatably installed in each first support roller bracket. The second support roller brackets are fixed on both sides of the bottom frame, and the second support rollers are rotatably installed on the second support roller brackets. A semi-circular auxiliary support plate is disposed between the upper ends of the two first support rollers and the lower ends of the second support rollers.

[0010] Furthermore, each end of the chain guide rail is fixed with a limiting seat.

[0011] Furthermore, the support frame includes a main frame and a powered roller bracket, the upper part of the main frame is open, and the powered roller bracket is fixed to the inner side of the main frame.

[0012] Furthermore, the displacement assembly includes a displacement motor, a transmission assembly, and a powered roller. The displacement motor is fixed on the main frame, and the powered rollers are rotatably and evenly spaced on a powered roller bracket. The displacement motor drives the powered rollers to rotate through the transmission assembly, thereby displacing the car.

[0013] Furthermore, the transmission assembly includes a driving sprocket, a driven sprocket, and a shifting chain. The driving sprocket is fixed to the drive end of the shifting motor, and the driven sprocket is fixed to the rotating shaft of the powered roller. The driving sprocket and the driven sprocket at the end are driven by a shifting chain, and shifting chains are also provided on two adjacent driven sprockets.

[0014] Furthermore, the displacement assembly consists of two parts: a non-powered roller bracket is fixed to one side of the support frame, and non-powered rollers are rotatably and evenly installed on the non-powered roller bracket.

[0015] Furthermore, the flipping component flips the support frame and its shifting component by 85 to 90 degrees each time.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model discloses an elevator car moving and tilting device, which utilizes a set of shifting components located at the bottom of the support frame for movement. The tilting components tilt the support frame, the shifting components on it, and the car as a whole. After the car tilts once, another set of shifting components drives the car to continue moving, thereby realizing the functions of moving and tilting the car. This facilitates subsequent processing of the bottom of the original car. The operation is simple, the tilting is labor-saving and safe, which can greatly reduce the labor intensity of workers, improve work efficiency, and ensure product quality.

[0018] 2. The present invention provides an elevator car moving and tilting device, which drives the tilting sprocket to rotate via a tilting motor, drives the bent plate to rotate via a chain guide rail, and then drives the support frame fixed at its top to rotate. During this process, the support sprockets on both sides cooperate with the chain guide rail to support the bent plate, which can ensure the stability of the support frame tilting and make the tilting of the elevator car safer.

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0026] The purpose of this invention is to address the shortcomings of existing technologies by providing an elevator car movement and tilting device.

[0027] Example 1

[0028] This embodiment provides an elevator car moving and tilting device, referring to... Figure 1As shown, the system includes a flipping assembly 20, a support frame 30, and a shifting assembly 40. Two or three shifting assemblies 40 can be provided. When there are three shifting assemblies 40, one is fixed to the bottom end of the support frame 30, and the other two are fixed to the two sides of the support frame 30. In this embodiment, there are two shifting assemblies 40, one fixed to the bottom end of the support frame 30 and the other fixed to one side end. This saves one shifting assembly 40 while still achieving the elevator car movement function. The support frame 30 is fixed to the drive end of the flipping assembly 20. The flipping assembly 20 flips the support frame 30, the shifting assemblies 40, and the car 10. The upper part of the support frame 30 is open, allowing the car 10 to be placed onto the support frame 30 from the open portion.

[0029] This utility model discloses an elevator car moving and tilting device. The car 10 is placed on a support frame 30. It is moved by a set of shifting components 40 located at the bottom of the support frame 30. The tilting component 20 tilts the support frame 30, the shifting components 40, and the car 10 as a whole. When the car 10 finishes tilting once, another set of shifting components 40, which was originally located on the side of the support frame 30, is now located at the bottom of the car 10, which can drive the car 10 to continue to move. This realizes the function of moving and tilting the car 10, which facilitates the subsequent processing of the bottom of the original car 10. The operation is simple, the tilting is labor-saving and safe, which can greatly reduce the labor intensity of workers, improve work efficiency, and ensure product quality.

[0030] Example 2

[0031] This embodiment provides an elevator car moving and tilting device, referring to... Figures 1-3 As shown, based on the structure in Embodiment 1, the flipping assembly 20 includes a main flipping structure and an auxiliary support structure. The main flipping structure includes a base frame 21, a flipping motor 22, a chain guide rail 26, and a bent plate 213. The flipping motor 22 is fixed to the central crossbar of the base frame 21 via a flipping motor frame. A flipping sprocket 23 is fixed on the shaft of the flipping motor 22. Two support sprocket brackets 24 are symmetrically fixed on both sides of the flipping sprocket 23 on the central crossbar of the base frame 21. A support sprocket 25 is rotatably installed in each support sprocket bracket 24. The chain guide rail 26 is fixed to the bottom end of the bent plate 213. The bent plate 213 is semi-circular. The chain guide rail 26 cooperates with the flipping sprocket 23 and the support sprocket 25 for transmission. In this embodiment, the preferred chain guide 26 is a double-row chain guide component in the prior art. The guide is made of polyethylene plastic, which has excellent impact resistance and self-lubrication. Two grooves are arranged side by side on the guide, and the double-row chains are installed side by side on the two grooves of the guide. The flip sprocket 23 and the support sprocket 25 are both double sprockets.

[0032] In this utility model, an elevator car moving and tilting device utilizes a tilting motor 22 to drive a tilting sprocket 23 to rotate during tilting. This rotation is transmitted through a chain guide rail 26, causing a bent plate 213 to rotate, which in turn drives a support frame 30 fixed at its top to rotate. Preferably, the tilting assembly 20 tilts the support frame 30 and its displacement assembly 40 by 85-90 degrees each time, thus achieving the tilting of the car 10 while preventing the car 10 from falling due to excessive tilting angle. Furthermore, in this embodiment, a limiting seat 212 is fixed at each end of the chain guide rail 26 to limit the rotation angle of the chain guide rail 26 and prevent excessive tilting. During this process, the support sprockets 25 on both sides cooperate with the chain guide rail 26 to support the bent plate 213, ensuring the stability of the tilting of the support frame 30.

[0033] Reference Figures 2-3 As shown, the auxiliary support structure is located on both sides of the main tilting structure, cooperating with the main tilting structure to provide auxiliary support for the support frame 30, ensuring its stability. Specifically, the auxiliary support structure includes a first support roller bracket 27, a first support roller 28, a second support roller bracket 29, a second support roller 210, and an auxiliary support plate 211. Four first support roller brackets 27 are symmetrically fixed at the ends of the bottom frame 21, with one first support roller 28 rotatably mounted in each bracket. The second support roller brackets 29 are fixed at the center of both sides of the bottom frame 21, and the second support rollers 210 are rotatably mounted on them. The semi-circular auxiliary support plate 211 is located between the upper ends of the two first support rollers 28 and the lower ends of the second support rollers 210. During the rotation of the support frame 30 driven by the chain guide rail 26, the auxiliary support plates 211 on both sides provide auxiliary support for the top-fixed support frame 30, thereby ensuring the stability of the tilting of the support frame 30.

[0034] Example 3

[0035] This embodiment provides an elevator car moving and tilting device, referring to... Figures 4-5 As shown, based on the structure in Embodiment 2, the support frame 30 includes a main frame 31 and a powered roller bracket 32. The upper part of the main frame 31 is open, and the powered roller bracket 32 ​​is fixed to the bottom and one inner side of the main frame 31. A non-powered roller bracket 34 is fixed to the other side of the main frame 31, and non-powered rollers 33 are rotatably and evenly spaced on the non-powered roller bracket 34. There is a height difference between the two sides of the main frame 31. The side with the powered roller bracket 32 ​​is higher than the side with the non-powered roller bracket 34. The height of the higher side of the main frame 31 is greater than the height of the car 10, and the height of the lower side of the main frame 31 is less than the height of the car 10, so that a part of the car 10 is located above one side of the main frame 31, which facilitates processing or inspection.

[0036] Reference Figure 5 As shown, the shifting assembly 40 includes a shifting motor 41, a transmission assembly, and powered rollers 45. The shifting motor 41 is fixed on the main frame 31. The powered rollers 45 are rotatably and evenly spaced on the powered roller bracket 32. The shifting motor 41 drives the powered rollers 45 to rotate through the transmission assembly, thereby shifting the car 10. Specifically, the transmission assembly includes a drive sprocket 42, a driven sprocket 43, and a shifting chain 44. The drive sprocket 42 is fixed to the drive end of the shifting motor 41. Each powered roller 45 has a driven sprocket 43 fixed on its shaft. The drive sprocket 42 and the driven sprocket 43 located at the end are transmitted through the shifting chain 44. Shifting chains 44 are also provided on two adjacent driven sprockets 43.

[0037] This utility model discloses an elevator car moving and tilting device, which can be installed in the process after the elevator car unloading and / or assembly process is completed. It is used to tilt the elevator car. In order to facilitate its use in conjunction with the elevator car processing production line, it can also move the elevator car so that the elevator car can be received and delivered before and after tilting.

[0038] In operation, the elevator car moving and tilting device of this utility model moves the car 10 from the previous process onto the support frame 30, and is then moved by a set of shifting components 40 located at the bottom of the support frame 30 to receive it. Specifically, the shifting components 40 are driven by a shifting motor 41 to rotate the drive sprocket 42, which in turn drives the powered roller 45 to rotate through the transmission component, thus shifting the car 10 on it. The tilting components 20 then tilt the support frame 30, the shifting components 40, and the car 10 as a whole. Specifically, the tilting components 20 are driven by a tilting motor 22 to rotate the tilting sprocket 23, which in turn drives the bent plate 213 to rotate through the chain guide rail 26, thereby rotating the support frame 30 fixed at its top and tilting the car 10 on it. When the car 10 finishes one rotation, another set of shifting components 40, which was originally located at the side of the support frame 30, is now located at the bottom of the car 10. This allows the car 10 to continue shifting and be transported to the next process, thus realizing the movement and rotation functions of the car 10. This facilitates subsequent processing of the bottom of the original car 10. The operation is simple, the rotation is labor-saving and safe, which can greatly reduce the labor intensity of workers, improve work efficiency, and ensure product quality.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
