Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a pulley storage and transfer device. Background Technology

[0002] Pulleys are components of lifting machinery. In the current production process, the produced pulleys are stacked in pallets, which is not stable enough. When they are stationary, the probability of problems is small, but during transportation, they are prone to tilting, collapsing, and bumping. This not only causes quality problems in the pulleys themselves, but also accelerates the wear and tear of the crane structure, affecting the safety of lifting operations and the life of the lifting equipment. Utility Model Content

[0003] The purpose of this invention is to provide a pulley storage and transfer device. This device has a simple structure and can stably fix the pulleys whether they are stationary or in a transport state, thus protecting the overall quality of the pulleys.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pulley storage and transfer device, including a base, a vertically arranged limiting shaft fixedly connected to the center of the base, the diameter of the limiting shaft being slightly smaller than the inner diameter of the pulley, and a lifting ring fixedly connected to the top of the limiting shaft, the width of the lifting ring being smaller than the diameter of the limiting shaft.

[0005] Optionally, a fixing nut is provided at the center of the base, and a fixing screw that matches the fixing nut is fixedly connected to the bottom of the limiting shaft. The fixing screw is threaded into the fixing nut.

[0006] Optionally, the top of the limiting shaft is provided with a mounting screw hole, and the bottom of the lifting ring is provided with a mounting screw that matches the mounting screw hole, and the mounting screw is threaded into the mounting screw hole.

[0007] Optionally, the lifting ring has an elliptical shape.

[0008] Optionally, a counterweight is provided at the bottom of the base.

[0009] The pulley storage and transfer device of this utility model has the following advantages:

[0010] (1) After the pulley is processed, it can be directly fitted into the limiting shaft. The gap between the limiting shaft and the center hole of the pulley is small, so the pulley will not wobble. The limiting shaft can play a good role in fixing it. The base has a large area and high stability. Even if the pulleys are stacked, they are not easy to tip over and can be stored stably. When the pulley is transported, the lifting ring can be directly connected to the hook to drive the pulley to transport, which saves time and effort and is highly efficient.

[0011] (2) The threaded connection between the limit rod and the base, and the threaded connection between the lifting ring and the limit rod are all for the purpose of facilitating the installation of the device.

[0012] (3) The counterweight can further improve the stability of the base. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model.

[0014] Figure 2 This is a schematic diagram of the limit shaft. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1-2 As shown, a pulley storage and transfer device includes a base 1, a limiting shaft 2, and a lifting ring 3. The base 1 is made of square steel plate, and a fixing nut 4 is set at the center of the base 1. A fixing screw 5 matching the fixing nut 4 is fixedly connected to the bottom of the limiting shaft 2. The fixing screw 5 is threaded into the fixing nut 4. The outer diameter of the fixing nut 4 is smaller than the diameter of the limiting shaft 2, and the diameter of the limiting shaft 2 is slightly smaller than the inner diameter of the center hole of the pulley. In this way, the limiting shaft 2 can smoothly pass through the center hole of the pulley, and the gap between the limiting shaft 2 and the center hole is small, so the pulley will not wobble significantly, resulting in high stability.

[0017] The top of the limiting shaft 2 has a mounting screw hole 6, and the bottom of the lifting ring 3 has a mounting screw 7 that matches the mounting screw hole 6. The mounting screw 7 is threaded into the mounting screw hole 6. The diameter of the lifting ring 3 is smaller than the diameter of the limiting shaft 2, so it does not affect the insertion of the pulley. The lifting ring 3 has an elliptical structure, which increases the inner hole area of ​​the lifting ring 3 and makes it easier to connect to the hook. The limiting rod is threaded to the base 1, and the lifting ring 3 is threaded to the limiting rod, which facilitates the installation and disassembly of the device.

[0018] During storage, the processed pulleys are directly stacked on the limiting shaft 2. The base 1 has a large area and high stability. In addition, the bottom of the base 1 is equipped with a counterweight 8, which can further lower the center of gravity of the device, preventing it from tipping over when the pulleys are stacked. During transportation, the hook is connected to the lifting ring 3 to lift the entire device and the pulleys together for transport, saving time and effort and increasing efficiency.

[0019] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
