Description

Technical Field

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

[0002] The counterweight is a component of the elevator traction system, and its function is to reduce the power of the traction motor and the torque on the traction sheave and worm gear.

[0003] The existing counterweight frame uses a clamping plate structure for the counterweight plate. During operation, the counterweight blocks collide with the counterweight plate, and after long-term use, the counterweight plate is prone to deformation or loosening. First, a loose counterweight plate increases the frequency of collisions between the counterweight blocks, increasing noise during elevator operation. Second, loosening of the counterweight blocks increases the probability of them becoming loose, which can easily lead to safety accidents. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides an elevator and its counterweight structure, which can improve the service life of the counterweight and reduce the noise during elevator operation.

[0005] To solve the above problems, this utility model proposes a counterweight frame structure for an elevator, including an upper clamping plate, columns, counterweight blocks, counterweight pressure blocks, and a lower clamping plate; the columns are vertically arranged at both ends of the upper clamping plate, and the upper clamping plate is connected to the lower clamping plate through the columns to form a counterweight frame.

[0006] Multiple counterweight blocks are stacked inside the counterweight frame, and counterweight pressure blocks are provided on the columns on both sides of the counterweight frame, with the counterweight pressure blocks abutting against the surface of the counterweight blocks.

[0007] The counterweight block includes a connecting plate, the bottom end of which is bent toward the other side column to form a first bent section, and the end of the first bent section is bent toward the upper clamping plate to form a second bent section; the connecting plate is fixedly connected to the column, and the first bent section abuts against the counterweight block.

[0008] As an improvement to the above technical solution, the column is provided with a plurality of adjustment holes at predetermined intervals, and the connecting plate is fixedly connected to the adjustment holes by fasteners.

[0009] As an improvement to the above technical solution, the first bending segment is parallel to the surface of the counterweight, and the second bending segment is parallel to the first bending segment.

[0010] As an improvement to the above technical solution, the length of the first bending segment is 6-15% of the length of the counterweight.

[0011] As an improvement to the above technical solution, the upper clamping plate is also provided with a counterweight wheel assembly;

[0012] The counterweight roller assembly includes a counterweight roller, a clamping plate, and a lower rope stop plate. The bearing ends of the counterweight roller are fixedly connected to the clamping plate. The bottom of the clamping plate is connected to the lower rope stop plate, and the lower rope stop plate is located below the counterweight roller. The clamping plate is fixedly connected to the upper clamping plate.

[0013] As an improvement to the above technical solution, both ends of the bearing of the counterweight wheel are provided with embedding grooves on the same side, and the bottom of the upper clamping plate can be embedded in the embedding grooves.

[0014] As an improvement to the above technical solution, the width of the clamping plate is 36-45% of the outer diameter of the counterweight wheel.

[0015] Accordingly, this utility model also provides an elevator, including the counterweight frame structure described above.

[0016] The following are the beneficial effects of implementing this utility model:

[0017] This utility model's counterweight block includes a connecting plate. The bottom end of the connecting plate is bent towards the opposite column to form a first bent section, and the end of the first bent section is bent towards the upper clamping plate to form a second bent section. The connecting plate is fixedly connected to the column, and the first bent section abuts against the counterweight block. Compared to existing technologies, the bottom of the counterweight block is bent in multiple sections. Compared to a clamping plate structure, this increases the contact area with the counterweight block, thereby increasing the stress-bearing area of ​​the counterweight block, reducing the probability of deformation, and thus solving the problem of deformation after prolonged use. It also extends the service life of the counterweight frame and reduces the noise generated during operation. Attached Figure Description

The connecting plate 41 is fixedly connected to the column 2, and the first bent section 42 abuts against the counterweight block 3. Compared with the prior art, the bottom of the counterweight block 4 is bent in multiple sections. Compared with the counterweight block with clamping plate structure, the contact area with the counterweight block 3 is increased, thereby increasing the stress area of ​​the counterweight block 4, reducing the probability of deformation of the counterweight block 4, and thus solving the problem of deformation of the counterweight block 4 after long-term use. It also extends the service life of the counterweight frame and reduces the noise generated by the counterweight frame during operation.

[0029] Preferably, the column 2 is provided with a plurality of adjustment holes 21 arranged at predetermined intervals, and the connecting plate 41 is fixedly connected to the adjustment holes 21 by fasteners 6.

[0030] Preferably, the first bent section 42 is parallel to the surface of the counterweight 3, and the second bent section 43 is parallel to the first bent section 42. The parallelism between the first bent section 42 and the surface of the counterweight 3 increases the contact area between them, thereby increasing the structural strength of the counterweight block 4.

[0031] Preferably, the length of the first bent segment 42 is 6-15% of the length of the counterweight 3.

[0032] Specifically, the upper clamping plate 1 is also provided with a counterweight wheel assembly 7;

[0033] The counterweight roller assembly 7 includes a counterweight roller 71, a clamping plate 72, and a lower rope-blocking plate 73.

[0034] Preferably, both ends of the bearing of the counterweight wheel 71 are provided with an embedding groove 711 on the same side, and the bottom of the upper clamping plate 1 can be embedded in the embedding groove 711.

[0035] Preferably, the width of the clamping plate 72 is 36-45% of the outer diameter of the counterweight wheel 71. This embodiment increases the area of ​​the clamping plate 72, resulting in better stress resistance than before. When the counterweight frame is impacted or subjected to excessive force, the risk of deformation of the clamping plate 72 and the counterweight wheel 71 detaching from the clamping plate is avoided.
