Description

Combined electric lifting device

technical field

The utility model relates to a lifting device, in particular to a combined electric lifting device for installing electric facilities.

Background technique

In the power transmission production work, when we want to replace a specific primary equipment in a certain interval, lifting operation is one of the most important operations. Especially in the overhaul and technical transformation work, it is often necessary to hoist some relatively simple primary equipment, such as the hoisting of isolating switches of 110kV and below; the hoisting of voltage transformers and current transformers of 110kV and below; the hoisting of arresters of 110kV and below . In previous hoisting operations, these hoisting tasks took up a lot of time, manpower and material resources in production and maintenance. Substation maintenance personnel usually decide how to carry out the lifting operation temporarily depending on the actual situation of the work site, and there is no unified and fixed lifting device and lifting method. Generally, it is directly hoisted by a crane, or it is hoisted by a manual vertical pole. Although these two hoisting methods have their own advantages, they all have great limitations at the same time. First, for some simple primary equipment of 110kV and below, if a crane is used to lift it, due to the large range of movement of the crane, in order to ensure a sufficient safety distance between the crane and the live parts of the equipment during operation, it is usually necessary to stop across the busbar of the operating equipment or adjacent to it. In the case of high power load, this method of expanding the scope of power outages is often not approved by the dispatching department, and it is necessary to passively wait for the power outage of related equipment when the load is low before carrying out hoisting operations, resulting in the overhaul and technical transformation plan not being completed in time. Moreover, the cost of crane hoisting is relatively high. The second is that although the manual vertical pole operation has relatively small requirements on the working environment and low cost, it is usually not required to cut off power at adjacent intervals, as long as there is no conductive part across the interval or across the interval on the working surface, a sufficient safety distance can be maintained , just can work, but need a large number of personnel to carry out construction, generally need 6-7 people to carry out work, workload and intensity of work are big, work efficiency is very low.

Utility model content

Aiming at the problems existing in the installation and lifting of electric equipment in the prior art, the utility model provides a combined electric lifting device suitable for installation and use of electric facilities in a single interval, which is safe and convenient.

The technical solution adopted for the technical problem to be solved by the utility model is: the combined electric hoisting device includes an electric hoist and a support pole, the electric hoist includes a steel rope and a pulley, and the support pole includes an upper support The supporting pole and the lower supporting pole, the upper supporting pole and the lower supporting pole are inlaid with tenons and connected with splints and screws, and the bottom end of the lower supporting pole is welded and fixed with a mounting bracket and a bottom plate. The electric hoist It is fixed on the mounting bracket, and a horizontal plate is arranged on the top of the upper supporting pole, and the pulley is movable on the horizontal plate.

According to the requirements of the lifting height, the utility model can also adopt tenons to be inlaid between the upper support rod and the lower support rod and be connected with one or more middle support holding rods by means of splints and screws.

When the maximum weight of the power facility is not greater than 800Kg, the support pole is made of No. 10 channel steel, and the maximum load of the electric hoist is 1 ton.

The combined lifting device described in the utility model comprehensively solves the problems existing in the installation of power facilities by means of crane mechanical operation and manual vertical pole operation. Time-saving, labor-saving, high-efficiency operation and low cost, thereby improving the work efficiency of lifting operations and ensuring that the construction period is completed on schedule. The preparation time and hoisting time for hoisting a group of 110kV and below primary equipment are short (the preparation time is generally 10 minutes, and the hoisting time does not exceed 4 minutes),

The utility model can be widely used in relatively simple hoisting work with less workload such as isolating switches, voltage transformers, current transformers and lightning arresters of 110kV and below. The use of the combined electric lifting device can not only achieve convenient use, safety and reliability, efficient operation, save time and effort, and save hoisting costs; it can also minimize the scope of power outages, shorten the time of power outages, and reduce Power loss.
