Description

Technical Field

[0001] The invention belongs to the technical field of transformer moving devices, and in particular relates to a dry-type transformer moving device. Background Art

[0002] At present, manual hydraulic forklifts are generally used to replace or install dry-type transformers, and manual hydraulic forklifts are used to complete the corresponding transportation, positioning, unloading, etc. However, due to the limitations of the bottom space of the dry-type transformer and the indoor working environment, as well as the technical shortcomings of the manual hydraulic forklift itself, it is difficult to safely and efficiently complete the installation and replacement of dry-type transformers only by ordinary hydraulic forklifts, and there are generally problems such as difficult construction, high risk, low efficiency, and poor operability.

[0003] The specific technical disadvantages of using a hydraulic manual forklift to transport dry-type transformers are as follows:

[0004] First, the forklift can only enter and exit from the bottom of the transformer, so the transformer can only be carried horizontally. Not only is it difficult to turn, but it is also difficult to avoid related obstacles and pass through related doors and spaces with smaller sizes, which not only increases the difficulty and intensity of the corresponding construction, but also reduces the handling efficiency of the dry-type transformer;

[0005] Second, the forklift can only support the dry-type transformer, and can neither reliably fix the dry-type transformer nor accurately and smoothly lift the transformer. Moreover, it is difficult to control the stability and balance of the dry-type transformer through the forklift handle. Not only is it easy to impact the dry-type transformer during unloading, but there is also a risk of the transformer tipping over;

[0006] Third, the forklift can only adjust the height, and the width of the thick bracket cannot be adjusted, which makes it difficult for the forklift to enter and exit the dry-type transformer and difficult to match the narrow space at the bottom of the transformer. Summary of the invention

[0007] In order to solve the above problems existing in the prior art, an object of the present invention is to provide a dry-type transformer moving device.

[0008] The technical solution adopted by the present invention is:

[0009] A dry-type transformer mobile device comprises a carrier for supporting the dry-type transformer and a fixed push-pull frame for clamping the dry-type transformer. The carrier is connected to a flip locking mechanism for clamping a lower core clamp of the dry-type transformer, and a liftable universal wheel is installed at the bottom of the carrier.

[0010] When the dry-type transformer needs to be transported, first adjust the relevant dimensions of the device, clamp the lower core clamp of the dry-type transformer on the carrier by flipping the locking mechanism, clamp the dry-type transformer by fixing the push-pull frame, and raise the dry-type transformer by adjusting the universal wheels that can be raised and lowered. After the universal wheels touch the ground, the dry-type transformer can be transported.

[0011] The carrier of the device is relatively thin and can pass through the narrow space at the bottom of the dry-type transformer. The fixed push-pull frame is fixed on the core clamp, and the length and position are adjustable, which is convenient for balanced push-pull of the transformer.

[0012] The device effectively improves the handling technology of dry-type transformers. It can move the transformer horizontally as well as vertically. It can also turn at will, avoid related obstacles, and pass through smaller doors and spaces. It can reduce the corresponding construction difficulty and intensity, and improve the efficiency of transformer moving operations.

[0013] As a preferred solution of the present invention, a lifting screw rod for lifting the dry-type transformer is connected between the carrier vehicle and the universal wheel.

[0014] As a preferred solution of the present invention, a hydraulic linkage device for lifting the dry-type transformer is connected between the carrier vehicle and the universal wheel.

[0015] The device can accurately and smoothly lift the dry-type transformer through a screw rod or hydraulic cylinder, safely and smoothly unload the transformer, and avoid impacting the transformer. The hydraulic cylinder can lift dry-type transformers of different sizes, and the screw rod device is generally used to lift smaller dry-type transformers.

[0017] The height and width of the tiltable fixed beam of the device are adjustable, and can be increased or decreased according to the needs of equipment fixation. Therefore, the device can fix lower dry-type transformers of different sizes, and can transport both three-phase dry-type transformers and single-phase dry-type transformers. In addition, the device can also transport other equipment.

[0018] When transporting a three-phase dry-type transformer with three core columns, two flip-adjustable fixing beams are generally used to fix the lower iron yoke. When transporting a single-phase dry-type transformer with two core columns, three flip-adjustable fixing beams are generally used to fix the lower iron yoke; two of them are at the ends of the lower iron yoke, and one is between the core columns to ensure the safe replacement or installation of the dry-type transformer.

[0019] As a preferred solution of the present invention, a flip locking mechanism is provided between adjacent core columns of the dry-type transformer.

[0020] As a preferred solution of the present invention, a plastic pad is connected between the tiltable and adjustable fixed beam and the upper iron yoke of the dry-type transformer. The plastic pad can prevent the iron yoke from being damaged.

[0021] As a preferred solution of the present invention, the fixed push-pull frame includes a plurality of adjustable push-pull vertical rods, a plurality of adjustable push-pull horizontal rods and a plurality of adjustable push-pull vertical rods, and the plurality of adjustable push-pull vertical rods, the plurality of adjustable push-pull horizontal rods and the plurality of adjustable push-pull vertical rods are connected to form a rectangular frame for clamping the dry-type transformer. The bottom support area of ​​the device is large, and the device is reliably fixed to the iron yoke. The fixed push-pull frame can smoothly move the transformer, and the risk of the transformer tipping over can be eliminated, so as to meet the needs of replacing or installing the dry-type transformer and safely moving the dry-type transformer.

[0022] As a preferred solution of the present invention, the adjustable push-pull vertical rod, the adjustable push-pull horizontal rod and the adjustable push-pull longitudinal rod are all connected with adjustment sleeves for adjusting the length.

[0023] As a preferred embodiment of the present invention, the lower adjustable push-pull longitudinal rod passes through the through hole on the lower core clamp of the dry-type transformer, and the upper adjustable push-pull longitudinal rod passes through the through hole on the upper core clamp of the dry-type transformer. The adjustable push-pull longitudinal rod passes through the through hole on the core clamp, which can make the dry-type transformer more securely fixed.

[0024] As a preferred solution of the present invention, a connecting ear is further connected to the upper adjustable push-pull longitudinal rod, and the connecting ear is connected to the upper core clamp of the dry-type transformer by a fixing screw; an adjusting handle is further threadedly connected to the upper adjustable push-pull longitudinal rod, and the adjusting handle and the connecting ear are respectively arranged on both sides of the channel steel of the upper core clamp of the dry-type transformer. After the connecting ear is clamped and fixed to the upper core, the adjusting handle further clamps the channel steel.

[0025] The beneficial effects of the present invention are:

[0026] 1. The carrier of the device is relatively thin and can pass through the narrow space at the bottom of the dry-type transformer.
