Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, and more specifically, to a car and an elevator. Background Art

[0002] Existing elevator cars consist of a car frame and a car platform. The car frame is a rectangular frame structure arranged horizontally and vertically. The car platform is located above the lower beam of the car frame and spans the lower beam in the front-to-back direction. The car platform is fixed to the lower beam, and the front and rear ends of the car platform form a cantilever structure relative to the lower beam. The door system is installed at the front and / or rear ends of the car platform. When the car is loaded or unloaded using heavy loading and unloading equipment (such as a forklift), the forklift enters the car through the car door system. The forklift generates a large bending moment at the door system on the car platform, causing bending deformation (i.e., bending of the cantilever structure) there, which can easily cause door system failure.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0026] The car provided by the embodiment of the present utility model is as follows Figures 1 to 3 、 Figures 5 to 7 As shown, it includes: a car frame 100, the car frame 100 includes a lower beam 110, the lower beam 110 is arranged horizontally; a car platform 200, the car platform 200 spans the lower beam 110 and is fixedly connected to the lower beam 110, and the car platform 200 is arranged horizontally; and an inclined support beam 300, the support beam 300 is located below the car platform 200, the lower end of the support beam 300 is fixedly connected to the lower beam 110, and the upper end of the support beam 300 is located on the side of the lower beam 110 and is fixedly connected to the car platform 200.

[0027] In this elevator car, the car frame 100 includes a lower beam 110, the car platform 200 spans the lower beam 110 and is fixedly connected to the lower beam 110, and the support beam 300 is arranged obliquely below the car platform 200. The lower end of the support beam 300 is fixedly connected to the lower beam 110, and the upper end of the support beam 300 is located on the side of the lower beam 110 and is fixedly connected to the car platform 200. The support beam 300 can enhance the structural strength of the cantilever structure formed by the car platform 200 on the lower beam 110, thereby preventing the cantilever structure from bending and deforming. Therefore, when this elevator car is used, the door system on the car platform 200 is less likely to bend and deform when subjected to a downward bending moment, and the door system is less likely to malfunction.

[0028] In some examples, such as Figures 1 to 7 As shown, the car also includes: a connecting beam 400, which is located below the car bottom 200, and the connecting beam 400 is arranged upright. The lower end of the support beam 300 is fixedly connected to the lower beam 110 through the connecting beam 400. In this way, the distance between the lower end of the support beam 300 and the car bottom 200 in the up and down directions is greater, so the inclination angle of the support beam 300 relative to the horizontal plane is greater and the pressure in the vertical direction that it can withstand is greater. Therefore, the support beam 300 has better supporting performance for the cantilever structure on the car bottom 200, and the cantilever structure is less likely to bend and deform.

[0029] In some embodiments, as Figure 1 As shown, the lower beams 110 include two lower beams 110, which are spaced apart and arranged in parallel and are both fixedly connected to the car platform 200. The upper end of the connecting beam 400 is located between the two lower beams 110 and is fixedly connected to both lower beams 110. The lower end of the connecting beam 400 is located below the lower beams 110 and is fixedly connected to the lower end of the support beam 300. The connecting beam 400 is fixed between the two lower beams 110. In this way, when either of the two cantilever structures formed by the car platform 200 is subjected to a large downward bending moment, the connection between the connecting beam 400 and the two lower beams 110 is not easily disengaged.

[0030] In some examples, such as Figure 1 、 Figure 2 、 Figures 5 to 7 As shown, the car also includes a reinforcement beam 500, which is located below the car floor 200 and affixed to the car floor 200 at the side of the lower beam 110. The upper end of the support beam 300 is affixed to the reinforcement beam 500. This solution uses the reinforcement beam 500 to provide a larger area of ​​support for the cantilever structure formed on the car floor 200, making the cantilever structure on the car floor 200 less susceptible to bending and deformation. Therefore, when this car is used in an elevator, the door system on the car floor 200 is less likely to bend and deform when subjected to downward bending moments, making the door system less prone to failure.

[0031] In some embodiments, as Figure 1 、 Figure 2 、 Figures 5 to 7 As shown, the reinforcing beam 500 (reinforcing beam 500 is configured as a channel steel) and the lower beam 110 (lower beam 110 is configured as a channel steel) are arranged parallel to each other and spaced apart. Alternatively, the reinforcing beam 500 can be arranged at an angle or perpendicular to the lower beam 110, and the objectives of this application can be achieved. Such arrangements do not deviate from the design principles of this utility model and will not be further elaborated here. All such arrangements are within the scope of protection of this application.

[0032] In some examples, such as Figure 1 、 Figure 2 As shown, two sets of support beams 300 and reinforcement beams 500 are located on either side of the lower beam 110, supporting the two cantilever structures formed by the car platform 200. This solution is suitable for elevators with dual-door systems (of course, it is also applicable to elevators with single-door systems) and can prevent bending and deformation of the two cantilever structures of the car platform 200. Each set of support beams 300 includes multiple support beams 300, which are arranged in parallel and spaced apart to better support the cantilever structure of the car platform 200. Each set of reinforcement beams 500 includes multiple reinforcement beams 500, which are arranged in parallel and spaced apart to better support the cantilever structure of the car platform 200.

[0033] In some embodiments, as Figure 1 、 Figures 5 to 7 As shown, the lower beam 110 is arranged in the left-right direction, and the car platform 200 spans the lower beam 110 in the front-to-back direction. One of the two sets of reinforcement beams 500 is fixed to the front end of the car platform 200, and the other is fixed to the rear end of the car platform 200. The upper end of the support beam 300 located on the front side of the lower beam 110 is fixedly connected to the reinforcement beam 500 at the front end of the bottom surface of the car platform 200, and the upper end of the support beam 300 located on the rear side of the lower beam 110 is fixedly connected to the reinforcement beam 500 at the rear end of the bottom surface of the car platform 200. In an elevator with a dual-door system, one door system is located at the front end of the top surface of the car platform 200, and the other door system is located at the rear end of the top surface of the car platform 200. This solution makes the door systems on the car platform 200 less likely to bend and deform when subjected to downward bending moments, and therefore less likely to malfunction. For elevators with a single door opening and closing system, the door system is arranged at the front end of the top surface of the car bottom 200. The front end of the car bottom 200 can be supported only by the support beam 300 on the front side of the lower beam 110, which can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the utility model and will not be repeated here. It should also fall within the scope of protection of this application.

[0034] It can be, for example Figure 1 、 Figure 2 and Figure 5 As shown, the car frame 100 includes a; or it can be, as Figure 6 and Figure 7 As shown, the car frame 100 includes a plurality of car frames 100, which are spaced apart and arranged in parallel along the front-to-back direction. The car platform 200 spans and is fixedly connected to the plurality of lower beams 110. The plurality of car frames 100 are located between two sets of support beams 300, and the lower end of each support beam 300 is fixedly connected to the adjacent lower beam 110. The plurality of car frames 100 can be two, three, or four car frames 100, etc., and all of these can achieve the objectives of this application. Such embodiments do not deviate from the design principles of this utility model and will not be further described here. All of these embodiments should fall within the scope of protection of this application.

[0035] In some examples, such as Figure 1 As shown, each car frame 100 further includes two vertical beams 120 and an upper beam 130 . The left and right ends of the upper beam 130 and the left and right ends of the lower beam 110 are connected by the two vertical beams 120 to form a frame-shaped car frame.

[0036] In one embodiment, if Figures 1 to 3 As shown, the support beam 300 includes an upper connecting plate 310, a supporting diagonal rod 320 and a lower connecting plate 330, and the supporting diagonal rod 320 connects the upper connecting plate 310 and the lower connecting plate 330. Figure 1 、 Figure 2 and Figure 4 As shown, the connecting beam 400 includes a mounting plate 420 and two supporting members 410. The two supporting members 410 are spaced apart and arranged in parallel. The mounting plate 420 is located below the two supporting members 410 and connects the two supporting members 410. Figure 1 and Figure 2 As shown, the support beam 300 is fixedly connected to the reinforcing beam 500 through the upper connecting plate 310, the support beam 300 is fixedly connected to the lower side portions of the two support members 410 of the connecting beam 400 through the lower connecting plate 330, and the upper side portions of the two support beams 410 are fixedly connected to the two lower beams 110.

[0038] This elevator has all the advantages of the elevator car provided by any of the above embodiments, which will not be described in detail here.

[0039] In summary, the car provided by the embodiment of the present invention has a car frame including a lower beam, a car floor spanning the lower beam and being fixedly connected to the lower beam, a support beam obliquely disposed below the car floor, the lower end of the support beam being fixedly connected to the lower beam, and the upper end of the support beam being located to the side of the lower beam and fixedly connected to the car floor. The support beam can enhance the structural strength of the cantilever structure formed by the car floor on the lower beam, thereby preventing the cantilever structure from bending and deforming. Therefore, when the car is used in an elevator, the door system on the car floor is less likely to bend and deform when subjected to a downward bending moment, and the door system is less likely to malfunction.
