Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and more specifically, to a counterweight frame for an elevator. Background Art

[0002] The function of the elevator's counterweight system is to balance the weight of the car, thereby achieving the energy-saving effect of the elevator. The counterweight system is mainly composed of a counterweight frame, a counterweight block, etc., and the counterweight block is installed on the counterweight frame.

[0003] In some new buildings, the top floor height of the elevator shaft is not enough when it is designed. Especially when renovating old buildings or installing elevators outdoors, the original building height space is limited, so there is often a situation where the top floor height of the elevator is not enough. In this case, the counterweight frame has a large height restriction. Once the weight balance provided is insufficient due to the size restriction of the counterweight frame, this may reduce the performance of the elevator.

[0004] In view of this, an improved counterweight frame for an elevator is urgently needed.

[0039] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0040] Figure 1 is a perspective schematic diagram of a counterweight frame for an elevator according to an exemplary embodiment of the utility model, Figure 2 It is a cross-sectional view of an additional counterweight part of a counterweight frame for an elevator according to an exemplary embodiment of the present invention.

[0041] Reference Figure 1 and Figure 2 The counterweight frame for an elevator of the utility model may include: an upper beam 1, a first column 2, a second column 3 and an additional counterweight part 4.

[0042] Specifically, the top of the first column 2 is connected to the first end of the upper beam 1, the top of the second column 3 is connected to the second end of the upper beam 1, and the second column 3 and the first column 2 extend in the vertical direction and are arranged opposite to each other. Figure 1 It is noted that the top of the first column 2 is connected to the left end of the upper beam 1 , and the top of the second column 3 is connected to the right end of the upper beam 1 .

[0043] According to an exemplary embodiment of the utility model, the upper beam 1, the first column 2 and the second column 3 can be formed by profiles or steel plates. The connection between the upper beam 1 and the first column 2 and the second column 3 can be welded, bolted, riveted or the like.

[0044] Both ends of the additional counterweight part 4 are respectively connected to the bottom of the first column 2 and the bottom of the second column 3 to provide additional counterweight.

[0045] Herein, the so-called "additional counterweight" means that without changing the dimensions of the counterweight frame, especially the dimensions in terms of height, additional counterweight (i.e., weight) can be provided on the basis of the existing counterweight blocks installed on the first upright and the second upright.

[0046] When the top floor height of the elevator is insufficient, it is not possible to achieve the required counterweight by increasing the dimensions of the counterweight frame (especially the dimensions in terms of height). In this case, a counterweight frame that can provide "additional counterweight" becomes particularly important.

[0047] Referring to Figure 1 and Figure 2 , according to an exemplary embodiment of the present invention, the additional counterweight portion 4 may include: a lower beam 41 and a plurality of counterweight blocks 42. Among them, the first end of the lower beam 41 is connected to the bottom of the first upright 2, the second end of the lower beam 41 is connected to the bottom of the second upright 3, and the lower beam 41 is provided with a receiving space 410 with an open top; the plurality of counterweight blocks 42 are arranged in the receiving space 410 and arranged side by side in the receiving space 410. In cooperation with Figure 1 description, the left end of the lower beam 41 is connected to the bottom of the first upright 2, and the right end of the lower beam 41 is connected to the bottom of the second upright 3.

[0048] Furthermore, the lower beam 41 may be formed in a "U" shape and include a first side surface 411, a second side surface 412, and a bottom surface 413; the bottom of the first side surface 411 and the bottom of the second side surface 412 are connected to two opposite sides of the bottom surface 413; a first flange 4111 is provided at the top of the first side surface 411, a second flange 4121 is provided at the top of the second side surface 412, and the first flange 4111 and the second flange 4121 extend towards each other.

[0049] However, according to another embodiment of the present invention, flanges may not be provided at the tops of the first side surface 411 and the second side surface 412.

[0050] In addition, the first side surface 411, the second side surface 412, and the bottom surface 413 may be formed as one body.

[0051] In the illustrated embodiment, the two ends of the lower beam 41 are bolted to the bottoms of the first upright 2 and the second upright 3, but this is not limiting.

[0052] According to another embodiment of the present invention, the lower beam may be formed in a U shape (not shown), and the shape of the outer surface assembly of the plurality of counterweight blocks may be matched with the shape of the inner surface of the lower beam.

[0053] The additional counterweight part 4 according to the exemplary embodiment of the present invention may further include a plurality of fixing bolts 43 , which may penetrate the first side surface 411 or the second side surface 412 of the lower beam 41 to tightly press against the plurality of counterweight blocks 42 disposed in the accommodation space 410 .

[0054] By arranging the plurality of fixing bolts 43 , the plurality of counterweights 42 may be prevented from moving in the accommodation space 410 to avoid generation of undesirable noise or the like.

[0055] In one embodiment, M6 or M8 bolts of appropriate length may be used as fixing bolts. Meanwhile, threaded holes matching with the fixing bolts are provided on the first side surface 411 and / or the second side surface 412 of the lower beam 41 .

[0056] After an appropriate number of counterweights have been placed in the accommodating space, the fixing bolt cooperates with the threaded hole on the first side or the second side so that the fixing bolt protrudes by an appropriate length relative to the inner surface of the first side and / or the second side to tighten the multiple counterweights arranged in the accommodating space.

[0057] In the exemplary embodiment of the present invention, the number of the counterweight blocks 42 is set to four, and the four counterweight blocks 42 are arranged side by side in the accommodation space 410, and two adjacent counterweight blocks 42 are in surface contact with each other.

[0058] However, those skilled in the art should understand that the number of counterweights 42 should not be limited to this, and any number of counterweights 42 can be provided according to actual application conditions. For example, the number of counterweights 42 can be provided to be three, four, five, or six. In particular, in order to achieve the desired weight balance, the number of counterweights 42 can also be provided to be one. In addition, the arrangement of multiple counterweights in the accommodation space is not limited to this, and the present utility model only exemplarily shows one arrangement.

[0059] In addition, the specifications of the counterweight 42 disposed in the accommodating space 410 may be different from the specifications of the counterweights mounted to the first and second columns, where the counterweights mounted to the first and second columns are counterweights in the conventional sense.

[0060] The counterweight block providing the so-called "extra counterweight" in the present invention may be a composite counterweight block, a pressed counterweight block or a combination thereof.

[0061] Alternatively, according to another embodiment of the present invention, the additional counterweight may include a plurality of counterweights, the plurality of counterweights are arranged side by side, and both ends of the plurality of counterweights are respectively mounted to the inner sides of the bottoms of the first column and the second column. In this embodiment, the additional counterweight does not include a lower beam, but the two ends of the counterweight are directly mounted to the bottoms of the first column and the second column.

[0062] Furthermore, in another embodiment of the present invention, the additional counterweight part may further include a plurality of mounting bolts, a portion of the plurality of mounting bolts may pass through the first column and the plurality of counterweight blocks to fix the first column and the plurality of counterweight blocks together, and another portion of the plurality of mounting bolts may pass through the second column and the plurality of counterweight blocks to fix the second column and the plurality of counterweight blocks together.

[0063] In detail, a portion of the multiple mounting bolts can pass through one end (for example, the left end) of the first column and the multiple counterweights, and another portion of the multiple mounting bolts can pass through the second column and the other end (for example, the right end) of the multiple counterweights, so that the multiple counterweights are fixed together with the first column and the second column.

[0064] Similarly, in another embodiment of the present invention, the number and arrangement of the plurality of counterweights may also be arbitrarily set according to actual application conditions.

[0065] In this case, the specifications of the counterweight block in the additional counterweight part can be the same as the specifications of the conventional counterweight block installed on the first column and the second column. However, those skilled in the art will appreciate that the specifications of the counterweight block in the additional counterweight part are not limited thereto.

[0066] As described above, the counterweight frame for an elevator of the utility model can save the height space required for the counterweight frame. Even when the top floor of the elevator is not high enough, sufficient weight balance can be ensured. Accordingly, the space requirement for the elevator shaft building itself can be reduced.

[0067] The above descriptions of the specific exemplary embodiments of the present invention are presented for the purpose of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise form disclosed, and it is obvious that many modifications and changes can be made according to the above teachings. The selection and description of the exemplary embodiments are to explain certain principles of the present invention and their practical applications, so that those skilled in the art can make and use various exemplary embodiments of the present invention and their different alternative forms and modified forms. The scope of the present invention is intended to be defined by the appended claims and their equivalents.
