Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment hoisting, in particular to a hoisting device. Background Art

[0002] Currently, the lifting of high-voltage equipment typically relies on large cranes or electric hoists. However, these devices are often expensive, complex to operate, and require a large operating space. In situations where space is limited or environmental conditions are complex, such as power maintenance or high-voltage equipment replacement, the use of large lifting equipment is not only uneconomical but also poses safety risks. This is particularly true for older substations, where the switchyard area is inaccessible to lifting vehicles.

[0003] A lever hoist is a simple, portable manual lifting tool. It can be used for lifting, pulling, lowering, and calibrating, typically with a lifting capacity of no more than 50 tons. It is widely used in industries such as shipbuilding, power generation, transportation, construction, mining, and postal and telecommunications, for equipment installation, lifting objects, and pulling machinery. While some existing manual lifting tools utilize manual hoists for lifting, their design is inefficient, resulting in poor stability and inconvenient operation, making them ineffective in meeting operational needs. For example, the lever hoist's height cannot be adjusted to suit the on-site operating environment.

[0004] Therefore, it is necessary to design a manual lifting device with simple structure, easy operation, safety and reliability, and adjustable lifting height, so as to better deal with the above problems. Utility Model Content

[0005] The utility model aims to provide a lifting device, so as to provide a manual lifting device which has a simple structure, is easy to operate, safe and reliable, and can adjust the lifting height.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] A lifting device includes a support rod and a base, wherein the support rod includes a head end rod, a tail end rod and multiple intermediate rods that are butt-jointed and assembled, the end of the head end rod is fixedly sleeved with a first connecting plate, the head end of the head end rod is installed with a manual hoist, the lifting end of the manual hoist is sleeved with a lifting rope and a lifting hook fixedly connected to the lifting rope, the head end of the tail end rod is fixedly sleeved with a second connecting plate, and the tail end of the tail end rod is fixedly connected to the base; the head end and the tail end of each intermediate rod are fixedly sleeved with a third connecting plate, and the first connecting plate and the third connecting plate located on the intermediate rod near the head end rod, the third connecting plate between adjacent intermediate rods, and the second connecting plate and the third connecting plate located on the intermediate rod near the head end rod are all fixed by bolts.

[0008] The working principle and beneficial effects of this utility model:

[0009] This solution involves disassembling the manual hoist, multiple intermediate rods, the head end rod, and the base for easy transport to the job site. The appropriate number of intermediate rods is then selected based on the desired lifting height. The intermediate rods, head end rod, and end rod are assembled and secured with bolts to ensure the support rod has a desired lifting height. The manual hoist is then mounted on the head end of the head end rod, the lifting rope is looped through the lifting end of the manual hoist, and the lifting hook is connected to the electrical equipment to be hoisted. The base provides stable support to prevent tipping or sliding during the lifting process. The electrical equipment is then hoisted upwards by operating the manual hoist.

[0010] This solution provides a lifting device with a simple structure and can be disassembled. The lifting height can be freely adjusted, making it suitable for work sites with limited space or complex environmental conditions. It is easy to operate, safe and reliable.

[0011] Preferably, the number of the intermediate rods is 2 to 8. The hoisting height can be changed multiple times by using 2 to 8 intermediate rods.

[0012] Preferably, the middle rod is provided with an anti-slip coating. The surface is covered with an anti-slip coating to enhance the grip.

[0013] Preferably, the number of the hoisting ropes is two, and the hoisting hooks are connected to both ends of each hoisting rope, respectively. Stable hoisting is achieved by using four hoisting hooks.

[0014] Preferably, the base is a circular structure, which increases the contact area with the ground.

[0015] Preferably, the head end rod, the end end rod and the plurality of intermediate rods are arranged at an angle, which can ensure that sufficient lifting force is provided. BRIEF DESCRIPTION OF THE DRAWINGS
