Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator equipment technology, and in particular to an upper frame structure for the top of an elevator. Background Technology
[0002] An elevator is a power-driven electromechanical device that uses a rigid guide rail cabin or steps running along a fixed route to transport people or goods vertically or horizontally. It includes passenger (freight) elevators, escalators, and moving walkways. Regardless of their drive method, elevators are conventionally considered a general term for vertical transportation tools within buildings. Vertical elevators require the process of ascending or descending, and maintenance personnel often need to climb to the top of the elevator to perform repairs. For example, Chinese patent CN202121308124.8 discloses a modular car frame and villa elevator, which includes: a frame body and surrounding panels; the frame body includes: an upper crossbeam, a lower crossbeam, a first column, and a front frame; the surrounding panels include: a car top, a car bottom, and side walls. This frame body uses sheet metal profiles, which are assembled and connected by screws, facilitating rapid assembly of the car frame and overcoming the shortcomings of welding methods in existing technologies. However, the frame also has four reinforcing beams arranged horizontally and vertically, which reduces the space under the car and narrows the range of the safety sunroof, making it inconvenient for maintenance personnel to enter and exit. Utility Model Content
[0003] In view of this, the present invention provides an upper frame structure for the top of an elevator to solve the above problems.
[0004] An elevator roof frame structure includes a car, an upper frame assembly disposed on the top of the car, two guide shoes respectively disposed on both sides of the upper frame assembly, and four reinforcing plates respectively disposed on one side of the two guide shoes. A skylight is provided in the top of the car. The upper frame assembly includes two parallel first C-shaped plates and two parallel second C-shaped plates. The two first C-shaped plates and the two second C-shaped plates correspond to the four edges of the car roof, and are alternately connected end-to-end to create a hollow section in the center, which corresponds to the skylight. The bottom plate at the center of each end of the second C-shaped plate protrudes from the two side walls to form a connecting portion, the length of which matches the depth of the two side walls of the first C-shaped plate. The connecting portion is inserted into the end of the first C-shaped plate, and the side wall end of the second C-shaped plate is attached to the first C-shaped plate.
[0005] Furthermore, one end of the sunroof is rotatably connected to the car, and the other end has a device that can be locked to the car.
[0006] Furthermore, the first C-shaped plate is fixed to the top of the car with screws.
[0007] Furthermore, the two guide shoes are respectively mounted on one side opposite to the two first C-shaped plates by screws.
[0008] Furthermore, a vertical track is provided on the side of the guide shoe away from the first C-shaped plate. This track protrudes from the side wall of the car and is mounted on the guide rail in the elevator shaft.
[0009] Furthermore, the four reinforcing plates are arranged in pairs on both sides of the upper frame assembly. One end of the reinforcing plate is fixed to one side of the first C-shaped plate with screws, and the other end is fixed to the bottom of the car with screws.
[0010] Compared with the prior art, the elevator top frame structure provided by this utility model improves the flatness of the upper frame assembly by inserting the connecting part on the second C-shaped plate into the end of the first C-shaped plate and fixing it by welding. The hollow part can maximize the space for opening the skylight, thereby expanding the installation range of the skylight to facilitate smooth entry and exit of personnel. Attached Figure Description
[0011] Figure 1 A schematic diagram of the upper frame structure of the elevator top provided by this utility model.
[0012] Figure 2 for Figure 1 An exploded view of the upper frame components of the upper frame structure at the top of the elevator. Detailed Implementation
[0013] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0014] like Figure 1 The diagram shown is a structural schematic of the upper frame structure of the elevator roof provided by this utility model. The upper frame structure includes a car 10, an upper frame assembly 20 disposed on the top of the car 10, two guide shoes 30 respectively disposed on both sides of the upper frame assembly 20, and four reinforcing plates 40 respectively disposed on one side of the two guide shoes 30. It is conceivable that the upper frame structure of the elevator roof also includes other functional modules, such as screw modules, welding modules, traction modules, etc., which are technologies known to those skilled in the art and will not be described in detail here.
[0015] The car 10 is a box-shaped space on the elevator, used to carry and transport people and goods. The structure and function of the car 10 itself are existing technologies and will not be described in detail here.
[0016] A skylight 11 is provided on the top of the car 10. One end of the skylight 11 is rotatably connected to the car 10, and the other end has a lockable device to the car 10, allowing the skylight 11 to be opened or closed so that people can climb to the top of the car 10 for maintenance work. It should be noted that the lockable device between the skylight 11 and the car 10 is prior art; it can lock or unlock the skylight 11 and is itself prior art, so it will not be described in detail here.
[0017] Please see Figure 2 The upper frame assembly 20 includes two parallel first C-shaped plates 21 and two parallel second C-shaped plates 22.
[0018] The first C-shaped plate 21 is fixed to the top of the car 10 by screws, thereby fixing the upper frame assembly 20 so that the remaining components can be mounted on the first C-shaped plate 21.
[0019] The bottom plate at the center of the two ends of the second C-shaped plate 22 protrudes from the two side walls to form a connecting part 23. The length of the protruding connecting part 23 matches the depth of the two side walls of the first C-shaped plate 21. Thus, the connecting part 23 can be inserted into the end of the first C-shaped plate 21, and the side wall end of the second C-shaped plate 22 can fit perfectly against the first C-shaped plate 21, thereby improving the flatness of the upper frame assembly 20.
[0020] Two first C-shaped plates 21 and two second C-shaped plates 22 correspond to the four edges of the top of the car 10. One end of each of the first C-shaped plates 21 is connected to one end of each of the second C-shaped plates 22, and the other end of each of the first C-shaped plates 21 is connected to the other end of each of the second C-shaped plates 22, thus alternating the two first C-shaped plates 21 and the two second C-shaped plates 22 and connecting them end to end, and fixing them by welding, thereby creating a hollow section 24 in the center. The hollow section 24 corresponds to the skylight 11. In this way, while stabilizing the structure of the upper frame assembly 20, it can also maximize the opening space of the skylight 11, thereby expanding the setting range of the skylight 11 to facilitate the smooth entry and exit of personnel.
[0021] The two guide shoes 30 are respectively mounted on the opposite side of the two first C-shaped plates 21 by screws. A vertical track 31 is provided on the side of the guide shoe 30 away from the first C-shaped plate 12. The track 31 protrudes from the side wall of the car 10 and is mounted on the guide rail in the elevator shaft, thereby ensuring that the car 10 can run smoothly along the guide rail, limiting its horizontal displacement through mechanical constraints and providing its guiding function.
[0022] The four reinforcing plates 40 are arranged in pairs on both sides of the upper frame assembly 20. One end of the reinforcing plate 40 is fixed to one side of the first C-shaped plate 21 by screws, and the other end is fixed to the bottom of the car 10 by screws. This can strengthen the structure of the upper frame assembly 20 and stabilize the connection between the upper frame assembly 20 and the car 10.
[0023] Compared with the prior art, the elevator top frame structure provided by this utility model improves the flatness of the upper frame assembly 20 by inserting the connecting part 23 on the second C-shaped plate 22 into the end of the first C-shaped plate 21 and fixing it by welding. The hollow part 24 can maximize the opening space of the skylight 11, thereby expanding the setting range of the skylight 11 to facilitate the smooth entry and exit of personnel.
[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
