Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a counterweight frame for an elevator. Background Technology

[0002] In current elevator designs, the space utilization rate of the counterweight frame is relatively low. When the top floor height of the shaft and the pit depth are limited, the height of the counterweight frame needs to be reduced accordingly, and the installation height of the counterweight also needs to be lowered. To meet this requirement, materials with higher density (such as steel plates or cast iron) are usually chosen as the counterweight, but this significantly increases costs. In conventional designs, composite counterweights are more common; although they are less expensive, they require more space due to their lower density. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose an elevator counterweight frame with high overall space utilization. Under the premise of installing counterweights of equal weight, it can effectively reduce the overall height of the counterweight frame, significantly save costs, and effectively meet the usage needs of elevator shafts in scenarios with limited space at the top and bottom of the shaft.

[0004] The technical solution of this utility model is implemented as follows: a counterweight frame for an elevator, including a counterweight upright beam, an upper connecting component, a lower connecting component, a counterweight body, and an adjusting seat;

[0005] The upper connecting component and the lower connecting component are arranged at intervals; the counterweight beam is connected between the upper connecting component and the lower connecting component.

[0006] The lower connecting component has an open-top counterweight space inside; and the lower connecting component has an assembly space that is recessed from the bottom into the counterweight space.

[0007] The counterweight is disposed within the counterweight space;

[0008] The adjustment seat is located within the assembly space and is fixedly connected to the lower connecting component.

[0009] Furthermore, the upper connecting assembly includes an upper plate and a counterweight wheel; two sets of upper plates are arranged at an interval, and their ends are respectively fixedly connected to the counterweight upright beams on the corresponding sides; the counterweight wheel is disposed between the two sets of upper plates; the central axis of the counterweight wheel extends in the front-rear direction and is fixedly connected to the upper plate.

[0010] Furthermore, the upper plate is provided with rope-blocking plates on the left and right sides of the counterweight wheel; a gap is formed between the rope-blocking plates and the wheel surface of the counterweight wheel.

[0011] Furthermore, a dust cover is provided on the upper plate above the counterweight roller.

[0012] Furthermore, the lower connecting assembly includes a lower plate; two sets of lower plates are arranged at intervals, forming the counterweight space between them; both ends of the lower plate are fixedly connected to the counterweight beams on the corresponding sides; the bottom edges of the two sets of lower plates are provided with notches; a reinforcing plate is connected between the two sets of lower plates on the sides of the notches; each of the reinforcing plates encloses the assembly space; the adjusting seat is connected to the reinforcing plate.

[0013] Furthermore, a fixed base plate is connected between the bottoms of the two sets of lower plates, located on the outside of the notch.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] This invention utilizes a combination of a counterweight space and an assembly space, with the assembly space recessed into the counterweight space. The adjustment seat is installed within the assembly space to reduce the height of the exposed connecting components. Furthermore, it fully utilizes the counterweight space surrounding the assembly space to arrange the counterweight. This combination results in a compact overall structure with high space utilization. While installing a counterweight of equal weight, it effectively reduces the overall height of the counterweight frame, significantly saving costs and effectively meeting the needs of elevator shafts with limited space at the top and bottom of the shaft.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] like Figure 1-4 The diagram shows a counterweight frame for an elevator as described in this embodiment, which is particularly suitable for use in scenarios where space is limited, such as the top floor or pit of an elevator shaft. The counterweight frame includes counterweight beams 3, an upper connecting assembly, a lower connecting assembly, a counterweight body 4, and an adjusting seat 5. The upper and lower connecting assemblies are arranged vertically at intervals, forming a height gap between them. The counterweight beams 3 are formed by bending steel plates. Two sets of counterweight beams 3 are arranged between the upper and lower connecting assemblies. The counterweight beams 3, the upper connecting assembly, and the lower connecting assembly together constitute the main frame of the counterweight frame.

[0024] In this embodiment, a counterweight space 21 with an open top is formed inside the lower connecting assembly. An assembly space 22, recessed from the bottom into the counterweight space 21, is also formed on the lower connecting assembly. Specifically, the lower connecting assembly includes a lower plate 2. Two sets of lower plates 2 are arranged at intervals, extending laterally. The aforementioned counterweight space 21 is formed between the two sets of lower plates 2. The two ends of the lower plates 2 are respectively fixedly connected to the corresponding counterweight beams 3 by bolts. Square notches 25 are machined at the bottom edges of the two sets of lower plates 2. Reinforcing plates 23 are connected between the three sides of the notches 25 of the two sets of lower plates 2. Each reinforcing plate 23 is welded and fixed to the lower plate 2. Each reinforcing plate 23 encloses the aforementioned assembly space 22. The aforementioned adjusting seat 5 is a conventional component in the field of elevator technology, and its function and purpose are common knowledge. The adjusting seat 5 is installed within the assembly space 22 and is fixedly connected to the reinforcing plate 23 at the top of the notch 25. The lower end of the adjustment seat 5 extends downward into the assembly space 22.

[0025] The aforementioned counterweight 4 is arranged within the counterweight space 21. The counterweight 4 can also be arranged in the space between the upper connecting component and the lower connecting component (i.e., the space above the counterweight space 21).

[0026] In this embodiment, a fixed base plate 24 is connected between the bottoms of the two sets of lower plates 2, located outside the notch 25. The fixed base plate 24 is welded and fixed to the lower plates 2 on both sides. The fixed base plate 24 can strengthen the connection between the lower plates 2 on both sides and support the counterweight 4.

[0027] In this embodiment, the aforementioned upper connecting assembly includes an upper plate 1 and a counterweight wheel 11. Two sets of upper plates 1 are arranged at intervals and extend in the left-right direction. The two ends of the upper plate 1 are respectively fixedly connected to the corresponding counterweight beam 3 by bolts. The aforementioned counterweight wheel 11 is arranged between the two sets of upper plates 1. The counterweight wheel 11 is a conventional component of the prior art, and its function is common knowledge. Hanging plates are installed on the upper plates 1 on both sides. The central axis of the counterweight wheel 11 extends in the left-right direction. A groove is machined on the central axis of the counterweight wheel 11. The hanging plates are locked into the grooves and then connected to the upper plate 1 by bolts, so that the counterweight wheel 11 is fixed to the upper plate 1. Rope guard plates 12 are installed on the upper plate 1 on the left and right sides of the counterweight wheel 11. A gap is formed between the rope guard plate 12 and the wheel surface of the counterweight wheel 11 to limit the steel wire rope on the counterweight wheel 11. A dust cover 13 is installed on the upper plate 1 above the counterweight roller 11 to protect the counterweight roller 11.

[0028] During assembly, the counterweight 4 is arranged within the counterweight space 21 and above it, according to actual needs. The adjusting seat 5 is fixedly installed in the assembly space 22 by bolts. The assembly space 22 is recessed into the counterweight space 21. When the adjusting seat 5 is installed in the assembly space 22, the height of the exposed lower connecting components of the adjusting seat 5 can be reduced. By making full use of the counterweight space 21 around the assembly space 22 to arrange the counterweight 4, the overall structural layout is compact and the space utilization rate is high. Under the premise of installing the same weight of counterweight 4, the overall height of the counterweight frame can be effectively reduced, significantly saving costs and effectively meeting the usage requirements of limited space in the top floor and pit of the elevator shaft.
