Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and in particular to a main frame of a household elevator. Background Art

[0002] Almost all elevators on the market need to set up pits, shafts and machine rooms. Maintenance devices, buffers and other equipment are installed through the pit setting, which has almost become the standard configuration of existing elevators. However, for some home elevators, the weight they carry is relatively small, and the corresponding maintenance equipment is also small in size. Setting up a pit specifically for installation will undoubtedly cause a great waste of data. On the other hand, during the installation process of the elevator, it is necessary to excavate the pit, which requires a lot of manpower and material costs. In addition, for some special terrains, such as where water pipes, cables and other equipment are installed below, they cannot be installed, which greatly limits the application scope of the elevator.

[0003] A special space also needs to be set up for the hoistway. For some places where hoistways cannot be provided, elevators cannot be installed, and the versatility is poor.

[0004] The power mechanism, electric control equipment, etc. are installed inside the machine room. However, the setting of the machine room occupies a large amount of living space, and for some home elevators, especially in places where the installation site is limited, it brings many inconveniences to its installation and users, limiting the scope of use of home elevators, and they need to be changed according to the size of the shaft, and cannot be universal. On the other hand, during the installation and later use, the elevator shaft, machine room, etc. need to be installed and maintained, resulting in high work intensity and high cost during the installation and later maintenance.

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0039] like Figure 1 As shown, the main frame of the home elevator of the present invention includes a bottom frame 1, a shaft frame 2 connected to the bottom frame 1, a power frame 3 located at the top of the shaft frame 2, a track 4 located inside the shaft frame 2, a speed limiter 5 for speed limiting, a traction machine 6 installed on the power frame 3, and an inspection box 7 located inside the shaft frame 2;

[0040] The shaft frame 2 includes a shaft column 21 and a shaft beam 22 connected to the shaft column 21 . The bottom of the shaft column 21 is connected to the bottom frame 1 , and the top of the shaft column 21 is connected to the power frame 3 .

[0041] like Figure 2 As shown, the bottom frame 1 is used to replace the traditional pit, without the need to dig a pit, saving space and site, and is suitable for various installation locations. It supports the shaft frame and raises the position of the inspection box and the speed limiter to a certain height to prevent water from entering the shaft frame, causing the internal circuit to be affected, thereby improving the reliability of the home elevator. The bottom frame 1 is a rectangular frame structure, including four interconnected support frames 11.

[0042] Specifically, the support frame 11 is used to support the shaft frame 2 and raise the shaft frame to a certain height to ensure that the components installed inside the shaft frame 2 (such as an inspection box, a speed limiter, etc.) are at a certain height from the ground, preventing water from accidentally entering the shaft frame 2 and affecting the normal use of electronic components such as the inspection box, thereby improving the safety performance of the elevator.

[0043] like Figure 3As shown, in order to achieve fixed installation between the support frame 11 and the hoistway frame 2 , a first limiting hole 12 is provided on the top of the support frame 11 to facilitate installation of the hoistway frame 2 on the support frame 11 .

[0044] like Figure 3-4 As shown, the shaft frame 2 is used to replace the traditional elevator shaft, which is connected to the bottom frame 1, and includes a shaft column 21 and a shaft beam 22 connected to the shaft column 21. The bottom of the shaft column 21 is connected to the bottom frame 1, and the top is connected to the power frame 3, forming the structure of the main frame.

[0045] Specifically, the shaft column 21 is made of aluminum alloy material, and its bottom is fixedly connected to the support frame 11, and second limiting holes 23 are provided at both ends. The shape, size and position of the second limiting hole 23 located at the bottom of the shaft column 21 match the shape, size and position of the first limiting hole 12, so as to facilitate extending the limiting column into the first limiting hole 12 and the second limiting hole 23, thereby realizing a fixed connection between the shaft column 21 and the support frame 11.

[0046] In order to achieve the fixed installation of the shaft beam 22, the shaft column 21 is also provided with a shaft connecting member 24 and a shaft mounting hole 25 located on the shaft connecting member 24. There are two shaft connecting members 24, which are respectively located on both sides of the shaft column 21. The two shaft connecting members 24 are perpendicular to each other, and the shaft mounting holes 25 on adjacent shaft columns 21 are arranged opposite to each other.

[0047] The shaft beam 22 is connected to the shaft column 21, and both ends thereof extend into the shaft mounting hole 25, respectively, to achieve a fixed connection between the shaft beam 22 and the shaft column 21. In this embodiment, there are multiple shaft beams 22, which are respectively located at the bottom, top and middle area of ​​the shaft column 21, to reinforce the main frame and ensure that the car can operate safely inside the main frame.

[0048] like Figure 5-6 As shown, the power frame 3 is used to replace the traditional elevator machine room, which is located at the top of the shaft frame 2, and includes a power outer frame 31, a power upper frame 32 located at the top of the power outer frame 31, and a power lower frame 33 located at the bottom of the power outer frame 31.

[0049] The power outer frame 31 constitutes the main structure of the power frame, which is convenient for the fixed installation of the track 4, the traction machine 6 and the speed limiter 5. It includes a power column 311, a power beam 312 connected to the power column 311, and a baffle 313 located between adjacent power beams 312. The power column 311 is used to support the power frame 3 and is made of aluminum alloy material. A first connecting piece 314 and a second connecting piece 315 are provided thereon. The first connecting piece 314 and the second connecting piece 315 are perpendicular to each other and have the same structure, and are used to achieve the connection between the power column 311 and the power beam 312. Correspondingly, the first connecting piece 314 and the second connecting piece 315 are both provided with a beam mounting hole 316, which facilitates the power beam 312 to extend into the beam mounting hole 316 to achieve the connection between the power column 311 and the power beam 312.

[0050] Correspondingly, in order to achieve a fixed connection between the power column 311 and the shaft column 21, a third limiting hole 317 is further provided in the power column 311. The third limiting hole 317 matches the shape, size and position of the second limiting hole 23 located at the top of the shaft column, so that the fixed connection between the shaft column 21 and the power column 311 can be achieved by extending the limiting column into the second limiting hole 23 and the third limiting hole 317.

[0051] Both ends of the power crossbeam 312 extend into the crossbeam mounting holes 316 of the adjacent power columns 311 , respectively, and cooperate with the power columns 311 to form a force-bearing structure of the power frame 3 , thereby facilitating the installation of the speed limiter 5 and the traction machine 6 .

[0052] The baffle 313 is located between adjacent power beams 312 and is used to protect the electrical structure inside the power outer frame 31 from damage. In order to prevent the heat generated when the electrical structure is working from accumulating and affecting the service life of the electrical structure, the baffle 313 is composed of a plurality of sub-baffles. The sub-baffles are arranged at an angle, and a certain gap is provided between adjacent sub-baffles, so that the heat inside the power outer frame 31 can be dissipated through the gap, thereby ensuring the service life of the internal electrical structure.

[0053] The power upper frame 32 is located at the top of the power outer frame 31. It is made of channel steel and spliced ​​into a rectangular structure, which is used to cooperate with the power frame to bear force. Accordingly, in order to increase the force of the power upper frame 32 and facilitate the installation of the traction machine and the speed limiter, the power upper frame 32 is also provided with a frame reinforcement rib 321 and a frame mounting hole 322 located on the frame reinforcement rib 321. While reinforcing the power upper frame 32, it also facilitates the installation of its internal components.

[0054] The power upper frame 32 is fixedly connected to the power outer frame 31. In order to strengthen the fixed connection between the power upper frame 32 and the power outer frame 31, an upper frame reinforcement plate 34 is also included. The upper frame reinforcement plate 34 is located between the power column 311 and the power upper frame 32, and is fixedly connected by screws to prevent the power frame from being subjected to excessive force and causing deformation of the power frame, thereby ensuring the safe operation of the elevator.

[0055] like Figure 7 As shown, the power lower frame 33 is located at the bottom of the power outer frame 31. It is made of channel steel processed and spliced ​​into a rectangular structure, which is used to cooperate with the power outer frame 31 to bear force. Accordingly, in order to increase the force of the power lower frame 33 and facilitate the installation of the traction machine 6 and the speed limiter 5, the power lower frame 33 is also provided with a lower frame reinforcement rib 331 and a lower frame mounting hole 332 located on the lower frame reinforcement rib 331, which not only reinforces the power lower frame 33, but also facilitates the installation of its internal components.

[0056] The power lower frame 33 is fixedly connected to the power outer frame 31. In order to reinforce the fixed connection of the power lower frame 33, a lower frame reinforcement plate 35 is also included. The lower frame reinforcement plate 35 is located between the power lower frame 33 and the external shaft column 21, and is fixedly connected by screws to prevent the power frame from being subjected to excessive force, causing deformation or position displacement of the power frame, thereby ensuring the safe operation of the elevator.

[0057] Here, by setting the power outer frame 31, the power upper frame 32, and the power lower frame 33, the fixed installation of the traction machine 6 and the speed limiter 5 is realized, and there is no need to set up a machine room, which saves production costs. On the other hand, the power frame does not need to be set according to the size of the elevator shaft, and is suitable for various elevator shafts. It has strong versatility and is easy to install, saving production costs and installation and maintenance costs.

[0058] The track 4 is located inside the shaft frame 2, one end of which is fixed to the shaft beam 22 located at the bottom of the shaft column 21, and the other end is fixed to the power lower frame 33, so that the elevator car can move along the track 4. Specifically, the cross section of the track 4 is a T-shaped structure, the end of which abuts against the support frame 11 and is fixedly connected to the shaft beam 22, so that the track 4 is fixedly installed.

[0059] The speed limiter 5 is used for speed limiting, and includes an internal speed limiter 51 located on the power frame 3 and a lower speed limiter 52 located on the support frame 11. The speed limiter 51 is fixed to the lower frame mounting hole 332 by screws, thereby achieving fixed installation of the speed limiter 51.

[0060] The traction machine 6 is located inside the power frame 3, and its structure is the same as the traditional structure, and is used to drive the elevator car to move up and down. Specifically, the traction machine 6 includes a body 61 and a traction belt buckle 52 connected to the body 51, the body 51 is fixed to the lower frame mounting hole 332 by screws, and the traction belt buckle 52 is fixed to the power lower frame 33, and is used to guide the traction rope to ensure that the elevator car can run normally.

[0061] The inspection box 7 is installed at the bottom of the shaft column 21, and the height of the bottom is greater than or equal to the height of the support frame 11, which is used to ensure that the inspection box 7 is not disturbed by external moisture, which affects the reliability of the inspection box 7 and ensures the safe operation of the elevator. Here, the inspection box 7 is set on the shaft column 21, which ensures the reliability of the electrical mechanism and the safe use of the elevator.

[0062] The main frame of the home elevator provided by the present invention replaces the traditional elevator pit, hoistway and machine room through the bottom frame 1, the hoistway frame 2 and the power frame 3, which is convenient for installation and transportation, saves space and production costs, has low requirements on the installation environment, and expands the application range of the elevator.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
