TECHNICAL FIELD
[0001] The utility model relates to a structure improvement of counterweight device, specifically a counterweight block anti-jumping device. BACKGROUND
[0002] The counterweight frame is a frame structure, and corresponding counterweights are arranged in the frame to correspond to the working load of the car. The counterweight is usually a counterweight block, which is stacked transversely in the counterweight frame and is buckled laterally at the end. However, since the counterweight frame mainly moves in the upward and downward directions, the counterweight block has an upward and downward inertia. Therefore, if not limited, the counterweight block will jump. The traditional anti-jumping device is to open long circular holes of different heights on the counterweight frame to fix and compress different numbers of counterweight blocks. However, since too many holes are opened, the structural strength of the counterweight frame is affected, and therefore it is not suitable for large-load counterweight frames, which need to be improved. SUMMARY
[0003] The utility model aims at overcoming the above-mentioned deficiencies in the prior art and providing a counterweight block anti-jumping device.
[0004] The utility model discloses a technical scheme for solving the above-mentioned problems: the anti-jumping device is fixed on the vertical beam of the counterweight frame, and includes a height fixing device and a counterweight block limiting device. The height fixing device is fixedly connected with the vertical beam and fixes the height position of the vertical beam. The counterweight block limiting device has a horizontal compression plate, which is in plane compression with the uppermost counterweight block. The anti-jumping device is fixed with the vertical beam through the designed fixing device, and does not rely on the structure on the vertical beam for fixation. The compression and fixation area of the counterweight block limiting device is large, which can effectively limit the upward and downward jumping of the counterweight block.
[0005] Further, the anti-jumping device is fixedly installed on the vertical beams on both sides and compressively fixes the surfaces of the counterweight blocks on both sides. The anti-jumping device is fixedly arranged at any height of the vertical beam. The anti-jumping device is correspondingly arranged at both ends of the counterweight block, and can be fixed at any position according to the stacking height of the counterweight block.
[0006] Further, the height fixing device includes a surrounding member, which is formed into a one-side-opened rectangular frame structure along the outer shape of the vertical beam. The surrounding member and the counterweight block limiting device form a complete rectangular surrounding frame, which is compressively and fixedly attached to the vertical beam. The fixed structure is fixed on the vertical beam by the surrounding member, and the clamping force of the surrounding structure is used to realize the fixation.
[0007] Further, the surrounding member and the counterweight block limiting device are fixedly connected by a fixing bolt. The adjustment of the clamping force is realized by the fixing bolt, and the clamping force is improved by the compression spring arranged on the fixing bolt.
[0008] Further, the counterweight limiting device comprises a fixed plate and a pressing plate, the fixed plate is arranged in opposition to the enclosing member, and the pressing plate is formed by bending the fixed plate, and the pressing plate is horizontally arranged and located at the bottom of the whole anti-jumping device.
[0009] Compared with the prior art, the anti-jumping device for the counterweight frame has the following advantages and effects: the design is an improved anti-jumping device for the counterweight frame of an elevator, has strong position fixing effect, has good effect on maintaining the structural strength of the counterweight frame, is convenient to install, and has stable and reliable structure.
