Abstract
Description
Technical Field
[0001] This utility model relates to an elevator, and more particularly to a low-rise electric elevator structure for home use. Background Technology
[0002] In existing ceiling-mounted home elevator installations, the main unit and pulley assembly are installed on the top surface of the elevator's top-floor frame structure, while the fixed brackets are located below the top-floor frame structure and fixed to the guide rails. Due to the location of the main unit and structural limitations, the overall height of the top-floor frame is too high, thus requiring a relatively high top floor of the elevator shaft. Increasing the top floor height of the elevator shaft for installation increases construction costs and renovation difficulties; installing a home elevator requiring a high top floor in older buildings encroaches on the interior space of the car, making the elevator feel cramped and uncomfortable, thus reducing its applicability. Currently, the minimum top floor height for ceiling-mounted elevators of various brands is generally around 3.2 to 3.8 meters (with a car height of 2.4 meters), which is still relatively high. This solution can achieve a top floor height of 2.4 meters with a minimum top floor height of 2.9 meters, offering a significant advantage. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a low-rise electric elevator structure for home use that saves space at the top of the elevator shaft.
[0004] The technical solution adopted by this utility model to solve its technical problem is: A low-rise electric elevator structure includes a top-floor frame and a main unit. The top-floor frame includes a main unit fixing base plate, and the main unit is fixed to the main unit fixing base plate and located below the main unit fixing base plate. The top-level frame also includes a main beam with a mounting groove. Several pulley assemblies are installed on the main beam and located in the mounting groove. One end of the main beam is fixed to the main unit mounting base plate.
[0005] The top-level frame also includes a fixed bracket, which is fixed to the other end of the main beam.
[0006] The top-level rack also includes a second fixed bracket arranged opposite to each other, which is fixed to both ends of the main unit's base plate.
[0007] The main beam is composed of two oppositely arranged channel steels, and the mounting groove is located between the two channel steels.
[0008] The top-level rack also includes a load-bearing beam assembly, which is fixed to the main unit mounting base plate. The load-bearing beam assembly is provided with a mounting groove, and a number of pulley assemblies are installed on the load-bearing beam assembly and located in the mounting groove.
[0009] The load-bearing beam assembly includes a first crossbeam, a second crossbeam, and a longitudinal beam. The first crossbeam and the second crossbeam are located on the corresponding side of the longitudinal beam and are fixed to the longitudinal beam in a cross shape. The first crossbeam is fixed to the main unit fixing base plate, and the mounting groove is provided in the first crossbeam and the second crossbeam.
[0010] The top-level rack also includes a fixed support that is arranged opposite to it, and the two ends of the longitudinal beam are fixed to the corresponding fixed support.
[0011] Both the first and second crossbeams are composed of two oppositely arranged channel steels, and the mounting groove is located between the two channel steels.
[0012] The host mounting base plate is equipped with a bent positioning plate.
[0013] The beneficial effects of this utility model are as follows: This utility model includes a top-level frame and a main unit. The top-level frame includes a main unit fixing base plate. The main unit is fixed to the main unit fixing base plate and the main unit is located below the main unit fixing base plate. By changing the position of the main unit, the height of the top-level frame is reduced, thereby reducing the maximum top-level height, saving construction and renovation costs, expanding the scope of application, and can still be installed in old houses with low top floors. It does not encroach on the car space, ensures that the interior height of the car is high enough, and increases comfort. Attached Figure Description

[0023] Reference Figures 1 to 4 This utility model discloses a low-top-floor electric elevator structure, including a top-floor frame 1 and a main unit 2. The top-floor frame 1 includes a main unit fixing base plate 11. The main unit fixing base plate 11 in this application is preferably made of a thicker steel plate. The main unit fixing base plate 11 is a square plate. Both ends of the main unit fixing base plate 11 are fixed to corresponding guide rails. The main unit 2 is fixed to the main unit fixing base plate 11 and is located below the main unit fixing base plate 11. The main unit 2 is installed below the main unit fixing base plate 11 by inverting, which reduces the height of the top-floor frame 1, thereby reducing the maximum top-floor height.
[0024] Of course, in order to enable the host 2 to be installed in an upside-down manner, we redesigned the structure of the top rack 1.
[0025] like Figure 1 As shown, Embodiment 1 is a design for the top-level rack 1: It also includes a main beam 12, one end of which rests on the main unit fixing base plate 11 and is fixed to the main unit fixing base plate 11 by screws, while the other end of the main beam 12 is fixed to the corresponding guide rail. The main beam 12 and the main unit fixing base plate 11 are set perpendicular to each other, so the top frame 1 forms a "T" shape with three fixing points, forming a stable triangular fixation, which is not only simple in structure but also has high strength.
[0026] As shown in the figure, the main beam 12 is provided with an installation groove 13. Several pulley assemblies 3 are installed on the main beam 12 and located in the installation groove 13. The installation groove 13 is open from top to bottom, which not only facilitates the installation of the pulley assemblies 3, but also facilitates the winding of the steel belt and pulleys below. In this application, three sets of pulley groups are installed in the installation groove 13, and the pulleys in the pulley groups are completely hidden in the installation groove 13, so as not to occupy the space outside the top frame 1, and to avoid the top frame 1 being relatively high even after the main unit 2 is inverted. As a specific preferred embodiment, in this application, the main beam 12 is composed of two oppositely arranged channel steels, which are arranged back to back on their sides. The installation groove 13 is located between the two channel steels. This not only allows the installation groove 13 to be directly formed, but also allows holes to be drilled in the side wall of the channel steels for screws to be directly fixed to the main unit fixing base plate 11, thereby saving processing steps and costs.
[0027] The top-level frame 1 also includes a first fixed bracket 14, which is fixed to the other end of the main beam 12. The first fixed bracket 14 is an "L"-shaped steel plate. One side plate of the first fixed bracket 14 is fixed to the other end of the main beam 12 by screws, while the other vertical side plate is fixed to the corresponding guide rail by screws. The top-level frame 1 also includes a second fixed bracket (15) arranged opposite to each other. The second fixed bracket 15 is fixed to both ends of the main unit fixing base plate 11. The second fixed bracket 15 is a "T"-shaped steel plate. The top plate of the second fixed bracket 15 is fixed to the main unit fixing base plate 11 by screws, while the other vertical plate is fixed to the corresponding guide rail by screws.
[0028] The specific installation method is as follows: Fixing bracket 14 and fixing bracket 2 15 are installed on the corresponding guide rails. Then, the main unit fixing base plate 11 and the main unit 2 are installed on the fixing bracket 2 15. Then, the main beam 12 with several pulley assemblies 3 is installed and fixed on the main unit fixing base plate 11. All the above installations are fixed by bolts. Then, the main unit 2 drives the car to move by passing the steel belt around each pulley, car and counterweight. This structure is suitable for the top-level frame with the counterweight on the side.
[0029] like Figure 2 and Figure 4 As shown, Embodiment 2 is another design for the top rack 1: The top-level frame 1 also includes a load-bearing beam assembly 16, which is fixed to the main unit mounting base plate 11. The load-bearing beam assembly 16 is provided with a mounting groove 13, and a plurality of pulley assemblies 3 are installed on the load-bearing beam assembly 16 and located in the mounting groove 13.
[0030] Specifically, the load-bearing beam assembly 16 includes a first crossbeam 161, a second crossbeam 162, and a longitudinal beam 163. The first crossbeam 161 and the second crossbeam 162 are located on opposite sides of the longitudinal beam 163 and are fixed to the longitudinal beam 163 in a cross shape. After the load-bearing beam assembly 16 is fixed to the main unit mounting base plate 11, the entire top-level frame 1 forms a cross shape. The end of the first crossbeam 161 is fixed to the main unit mounting base plate 11. The mounting groove 13 is provided in the first crossbeam 161 and the second crossbeam 162. The mounting groove 13 is divided into two parts by the longitudinal beam 163. The above forms a top-level frame structure with a rear-mounted counterweight. In this application, three sets of pulley blocks are installed on the longitudinal beam 163. In the mounting groove 13 between 63 and the main unit fixing base plate 11, the longitudinal beam 163 is preferably an I-beam, while the first crossbeam 161 and the second crossbeam 162 are both composed of two oppositely arranged channel steels. The two channel steels are arranged back to back and sideways. The mounting groove 13 is located between the two channel steels. This not only allows the mounting groove 13 to be directly formed, but also allows the side groove wall plate of the first crossbeam 161 to be directly drilled and screwed to be fixed to the main unit fixing base plate 11, thereby saving processing steps and costs. The ends of the first crossbeam 161 and the second crossbeam 162 can be cut and bent at ninety degrees to form a connecting plate, and then fixed to the longitudinal beam 163 with screws, thereby saving processing steps and costs.
[0031] The top-level rack 1 also includes a fixed bracket 14 arranged opposite to each other, and the two ends of the longitudinal beam 163 are fixed to the corresponding fixed bracket 14; the top-level rack 1 also includes a fixed bracket 25 arranged opposite to each other, and the fixed bracket 25 is fixed to the two ends of the main unit fixing base plate 11. The structure of the fixed bracket 14 and the fixed bracket 25 and their fixing to the guide rail are the same as described in Embodiment 1, and therefore will not be described in detail.
[0032] As a preferred structure, the main unit fixing base plate 11 is provided with a bent positioning plate 111, so that when installing the main beam 12 or the load-bearing beam assembly 16, the positioning plate 111 can position the main beam 12 or the load-bearing beam assembly 16 to facilitate installation.
[0033] In summary, this utility model provides a simple, easy-to-install, and low-ceiling-height ceiling-mounted elevator main unit frame structure, thereby realizing a ceiling-mounted elevator structure with a low ceiling.
[0034] The above provides a detailed description of a low-rise electric elevator structure for home use provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
