Background

The elevator has various structures, the arrangement of the car guide rails is commonly provided with double guide rails and six guide rails, and the rare four-guide-rail structure is only used in special conditions. The double guide rails are the most common arrangement, and the structure has the disadvantages that the structure is not suitable for being adopted when the tonnage of the elevator is large, and the problem of the stability of the elevator is easy to occur. The six guide rails are common, but when the tonnage of the elevator is smaller, the six guide rails are not suitable for use, and the cost is increased, so that the six guide rails are not suitable for use. The existing four-guide-rail structure is relatively wasted in arrangement space in a shaft, so that the four-guide-rail elevator shaft mechanism is adopted only in large tonnage, and popularization and use of the four-guide-rail elevator shaft mechanism are greatly limited.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, detachable connections, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the utility model can be understood according to specific situations by those skilled in the art.

As shown in fig. 2, the utility model provides a four guide rail elevartor shaft structures, include: the elevator comprises counterweight component 1 and guide rail components 2, wherein the counterweight component 1 is arranged on the elevator shaft side wall, specifically, the counterweight component 1 can be arranged on other three elevator shaft side walls except one side of an elevator door 100, the number of the guide rail components 2 is four;

the guide rail assemblies 2 comprise guide rails 21 and bases 22, four bases 22 are symmetrically arranged on two side walls adjacent to the elevator door 100, namely two guide rail assemblies 2 are arranged on one side wall adjacent to the elevator door, the other two guide rail assemblies 2 are arranged on the other side wall adjacent to the elevator door 100, the distance between the two guide rail assemblies 2 on one side of the elevator door 100 and the side wall on one side of the elevator door 100 is equal, the distance between the other two guide rail assemblies 2 and the side wall on the opposite side of the elevator door 100 is equal, and the guide rails 21 are arranged on the bases 22.

As shown in fig. 1 and 2, the utility model provides a four guide rail elevator well structures, it is for the four guide rail elevator well structures of large-tonnage among the prior art (as shown in fig. 1), and it all sets up all guide rail set 21 on the lateral wall of elevator well, rather than on the counterweight housing, so the elevator well of this structure compare in the present four guide rail elevator well of large-tonnage in fig. 1 can save out width L on the width.

As shown in fig. 3 and 4, compared with the structure of the small-tonnage dual-guide-rail elevator shaft in the prior art (as shown in fig. 3), the mechanism can use the car 200 with a larger size compared with the prior art when the elevator shaft with the same size as the prior art is used, thereby greatly improving the space utilization rate of the elevator shaft.

In a further improvement, two of the guide rail assemblies 2 are close to the elevator door 100, and the other two guide rail assemblies 2 are close to the other side opposite to the elevator door 100. Compared with the prior art that the guide rail is arranged between the elevator door and the side wall opposite to the elevator door (as shown in figure 1), the guide rail component of the structure is arranged at a position closer to the elevator door and the other side opposite to the elevator door, so that when the goods with heavy weight are moved into the elevator, the elevator adopting the four-rail elevator shaft structure has stronger stability and higher safety.

In a further improvement, the counterweight assembly 1 comprises: the elevator counterweight comprises longitudinal beams 11, counterweight blocks (not shown) and counterweight wheel units 12, wherein the counterweight wheel units 12 comprise counterweight wheels and corresponding components for fixedly supporting the counterweight wheels (the specific structure of the counterweight wheel units is mature in the prior art and is not the invention point of the technical scheme, so that the detailed description is omitted here), the two longitudinal beams 11 are vertically arranged on the side wall of one side of the elevator hoistway adjacent to the elevator door, and the counterweight blocks and the counterweight wheel units 12 are arranged on the two longitudinal beams 11. Because the guide rail subassembly in this mechanism has installed on the lateral wall, but not on the counterweight frame among the prior art, consequently, counterweight frame subassembly among this structure compares in prior art to counterweight frame subassembly, need not to be used for setting up the counterweight crosspiece support 13 of guide rail at counterweight frame shelf location, greatly reduced to counterweight frame subassembly's total weight, because of need not to install the guide rail at the support moreover, also less total length of support greatly, further reduced counterweight frame subassembly's total weight.

In a further improvement, the two guide rail assemblies 2 are respectively arranged at two lateral sides of the counterweight assembly 1, one guide rail assembly 2 is close to one side of the elevator door, and the other guide rail assembly 2 is close to the other side opposite to the elevator door.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
