Description

Small electrical equipment landing gear

technical field

The utility model relates to a lifting device used in electric power construction, in particular to a landing gear for lifting small electric power equipment.

Background technique

In the construction of power maintenance and maintenance, some small power equipment such as voltage transformers and current transformers are often replaced, so the equipment needs to be lifted and lowered. Because it is unsafe and uneconomical to use a crane on site, wooden bars and pulleys are still used. Such as the traditional manual lifting method, the high-altitude operation is inconvenient and unsafe, the labor intensity of the staff is high, the work efficiency is low, the power outage operation time is long, the dangerous point cannot be effectively controlled, and the operation in the range of small power outage intervals is directly unsafe for the safety of the power grid. factor.

Contents of the invention

The purpose of this utility model is to solve the above problems, to provide a kind of small electric equipment undercarriage that can shorten the maintenance power outage time, improve work efficiency, and ensure equipment and personal safety.

The lower part of the landing gear of the utility model small electric equipment is set as a bottom plate connected with the equipment base, the bottom plate is provided with a fixed outer sleeve, the outer sleeve is provided with a rotatable inner tube, the upper end of the inner tube is provided with a transverse support rod, and the support rod There is a manual hoist on it.

As an improvement of the utility model, the outer sleeve and the inner tube are provided with corresponding positioning pins and positioning holes.

As yet another improvement of the utility model, several movable pads are arranged inside the outer casing.

When the utility model is used, the bottom plate and the equipment base are fixed together, the number of movable pads is selected according to the lifting height, and then the lower end of the inner tube is inserted into the outer tube, the hook of the manual hoist is used to hook the equipment to be hoisted, and the hand is pulled The zipper can realize the lifting and lifting operation of small electric equipment. Compared with the original manual lifting method for lifting small power equipment such as voltage transformers and current transformers, it can reduce the number of construction personnel by half and the working time by one third, improve work efficiency, reduce labor intensity of workers, and shorten the power grid. During power outages, equipment and personal safety are guaranteed.

Detailed ways

As shown in Figure 1, the landing gear of the utility model small-sized electric equipment mainly includes a base plate 2, an outer casing 3, an inner tube 4, a transverse support rod 5, etc., and the base plate 2 and the equipment base 1 are fixed together during hoisting operations, such as The channel steel 7 is placed under the equipment base 1, and the bottom plate 2 and the channel steel 7 are fixed on the equipment base 1 with fastening bolts 8. An outer sleeve 3 is fixedly arranged above the bottom plate 2, and a rotatable inner tube 4 is inserted in the outer sleeve 3. In order to strengthen the connection strength between the outer sleeve 3 and the base plate 2, several cable-stayed pipes 9 can be added between the outer sleeve 3 and the base plate 2. In order to fix the inner tube 4 and the outer tube 3 when necessary, the inner tube 4 and the outer tube 3 can have corresponding positioning holes 32, and when fixing, insert the positioning pin 31 in the positioning holes 32 and get final product. The upper end of the inner tube 4 is fixedly equipped with a transverse support rod 5 , and a hand hoist 6 is installed below the transverse support rod 5 . Pull the hand chain 61 of the manual hoist 6 to lift and drop small electric equipment 10 such as voltage transformers. In addition, in order to adjust the height of the transverse support rod 5, a movable spacer 33 can be placed in the outer sleeve 3, and the movable spacer 33 adopts a spacer with the same diameter as the inner tube 4, and the quantity can be selected according to the height to be adjusted.
