Description

Technical Field

[0001] The utility model belongs to the technical field of elevator accessories, and particularly relates to an elevator counterweight frame with a T-shaped middle beam. Background Art

[0002] The counterweight frame is an important component of the elevator system. Its function is to balance the deadweight of the car and half of the rated load, thereby reducing the power and torque of the traction machine and achieving the goal of energy conservation and emission reduction.

[0003] The structure of the counterweight frame has no fixed form. The counterweight frame is located in the shaft and is connected to the car through the traction rope and the traction wheel. During the operation of the elevator, the counterweight frame slides on the counterweight guide rail through the counterweight guide shoe to play a balancing role. The counterweight frame consists of two parts: the frame and the counterweight block.

[0004] At present, the counterweight frame of the freight elevator is generally multi-row due to the large shaft. In order to effectively fix the counterweight block, the middle beam of the counterweight frame is generally:

[0005] The use of C-shaped outward-facing notched bent plates has low strength and occupies counterweight space, or back-to-back channel steels set between the upper and lower beams is expensive and very wasteful.

[0006] For example: Chinese utility model patent: CN202222691722.9, which discloses "a counterweight frame structure for a freight elevator", its specification discloses: the middle vertical beam includes two closely arranged channel steels, and the notches of the two channel steels are arranged back to back. Since the width of the freight elevator counterweight frame is relatively wide, the cost of using two closely arranged channel steels as the middle beam is very high, and the material is relatively wasteful. Moreover, the counterweight blocks of this counterweight frame can only be placed obliquely. After the counterweight blocks are fully stacked to the full height, the counterweight block at the highest point is still a large distance from the upper beam, which seriously reduces the counterweight stacking space.

[0007] When installing the counterweight blocks on the current counterweight frame, the counterweight frame needs to be placed obliquely into the counterweight frame, which greatly occupies the counterweight space. As a result, either the counterweight space is not sufficient, resulting in the inability to arrange the production design plan, or most of the low-cost composite counterweight blocks will be replaced with expensive cast iron counterweight blocks.

[0008] Therefore, an elevator counterweight frame with a T-shaped middle beam is designed to overcome the above problems. Utility Model Content

[0009] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an elevator counterweight frame with a T-shaped middle beam which has a simple and reasonable structure, is firm and reliable, and has stable operation.

[0010] The utility model is realized through the following technical scheme: an elevator counterweight frame with a T-shaped middle beam, which includes an upper beam, a lower beam and a straight beam, wherein two straight beams are provided, which are respectively installed on both sides of the upper beam and the lower beam to form a frame, and an middle beam is also installed between the two straight beams and between the upper beam and the lower beam. The middle beam divides the entire frame into two left and right chambers, each of which is equipped with multiple counterweight blocks, and car top wheels are respectively installed on the top of the two chambers.

[0011] Preferably, there are two intermediate beams, which are respectively installed in the middle position of the upper beam and the lower beam and arranged relative to each other. Both are T-shaped beams, wherein the T-shaped beam on one side is a complete one, and the T-shaped beam on the other side is composed of an upper T-shaped beam and a lower T-shaped beam, and the upper T-shaped beam and the lower T-shaped beam are spliced ​​together by a T-shaped connecting beam to form a whole beam, the upper T-shaped beam is fixed to the upper beam above, and the lower T-shaped beam is fixed to the lower beam at the bottom.

[0012] Preferably, the upper T-beam and the lower T-beam are both provided with a plurality of through holes, and the T-shaped connecting beam is also provided with a plurality of through holes. The upper T-beam, the lower T-beam and the T-shaped connecting beam are connected through the through holes, and the spacing between the upper T-beam and the lower T-beam can be adjusted.

[0013] Preferably, the two intermediate beams are secured together by a plurality of bolts. The bolts are located on one side of the T-shaped beam and have threads at both ends, secured by nuts at both ends. Furthermore, a spacer is installed outside the nut on the opposite outer side. The bolts and the inner and outer nuts prevent relative displacement between the two intermediate beams.

[0014] The beneficial effects of the utility model are as follows:

[0015] This utility model features a T-shaped intermediate beam elevator counterweight frame with two intermediate beams. One intermediate beam is a complete T-beam, while the other is composed of an upper T-beam and a lower T-beam. This design not only improves strength but also solves the problem of counterweights not being able to be stacked to the top. Furthermore, by increasing the number of counterweights that can be placed, the need for cast iron counterweights is significantly reduced, saving material. The two intermediate beams are secured with multiple bolts, ensuring that they do not move relative to each other and saving material. BRIEF DESCRIPTION OF THE DRAWINGS
