Description

Technical Field

[0001] The utility model relates to the technical field of transformer bushing transportation, in particular to an internal fixing structure of a UHV bushing packaging box. Background Art

[0002] The transformer bushing is the main insulating device outside the transformer box. It is easy to be damaged due to bumps and vibrations during transportation. In order to avoid the above problems, the transformer bushing is usually completely fixed in a packaging box or a transport box in the prior art. However, due to its large size and weight, the inertial force generated by vibration or impact during transportation is much higher than that of conventional products. If the conventional transportation plan is still used, it is easy to cause accidents and cause quality risks to the product. However, there is no special fixing structure for ultra-high voltage bushings in the prior art.

[0003] For example, a Chinese utility model patent with authorization announcement number CN212606612U discloses a transportation box for transformer bushings, but the device is mainly aimed at conventional bushing structures, and the device is designed to facilitate the storage and removal of transformer bushings.

[0004] For example, a Chinese utility model patent with authorization announcement number CN219361723U discloses a high-current bushing liner transport box, which includes an upper shell, a lower shell and other structures. However, the device is mainly designed for high-current bushings with special shapes and cannot be used for transporting ultra-high voltage bushings with large volume and weight. Utility Model Content

[0005] The utility model aims to provide an internal fixing structure of a UHV bushing packaging box, which solves the problem of UHV bushings moving inside the packaging box due to inertia during transportation, thereby ensuring that the UHV bushings will not be damaged during transportation.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A fixing structure inside a UHV bushing packaging box comprises a packaging box body, and limit frames are arranged inside both ends of the packaging box body, a head limit assembly is arranged inside the head of the packaging box body, and the head limit assembly comprises a head upper limit seat and a head lower limit seat for clamping the head of the UHV bushing, and a tail limit assembly is arranged inside the tail of the packaging box body, and the tail limit assembly comprises a tail upper limit seat and a tail lower limit seat for clamping the tail of the UHV bushing.

[0008] An adjustable auxiliary limit plate is provided on the head lower limit seat, a first tail lower limit groove and a second tail lower limit groove are provided on the tail lower limit seat, and the UHV bushing is limited in forward and backward displacement by the limit table formed between the auxiliary limit plate and the first tail lower limit groove and the second tail lower limit groove.

[0009] A mounting frame is provided on the lower limit seat of the head, and the auxiliary limit plate is mounted on the mounting frame through an adjusting bolt.

[0010] The head lower limit seat is fixedly arranged in the packaging box body, and the two ends of the head upper limit seat and the two ends of the head lower limit seat are respectively connected by corresponding head screws.

[0011] The lower side of the head upper limit seat is provided with a first head upper limit groove and a second head upper limit groove, the upper side of the head lower limit seat is provided with a head lower limit groove, and the first head upper limit groove, the second head upper limit groove and the head lower limit groove are all provided with a first buffer pad.

[0012] The tail lower limit seat is fixedly arranged in the packaging box body, and the two ends of the tail upper limit seat and the two sides of the tail lower limit seat are respectively connected by corresponding tail screws.

[0013] A tail upper limit groove is provided on the lower side of the tail upper limit seat, a first tail lower limit groove and a second tail lower limit groove are provided on the tail lower limit seat, and a second buffer pad is provided on the tail upper limit groove, the first tail lower limit groove and the second tail lower limit groove.

[0016] The advantages and positive effects of the utility model are:

[0017] 1. The utility model solves the problem that the UHV bushing moves in the packaging box due to inertia during transportation. When the UHV bushing is packed, the utility model first cooperates with the limiting table formed by the auxiliary limiting plate on the head lower limiting seat and the first tail lower limiting groove and the second tail lower limiting groove on the tail lower limiting seat to preliminarily limit the front and rear displacement of the UHV bushing, and then uses the head upper limiting seat and the head lower limiting seat to clamp the bushing head and uses the tail upper limiting seat and the tail lower limiting seat to clamp the bushing tail to prevent the bushing from moving up and down and shaking left and right. Finally, limiting frames are installed at both ends of the packaging box to ensure that the bushing will not move back and forth due to its own inertia, thereby ensuring that the UHV bushing will not be damaged during transportation.

[0018] 2. The utility model provides buffer pads at all places in contact with the UHV bushings to ensure safe transportation of the bushings. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The working principle of the utility model is:

[0035] The utility model comprises the following steps when used:

[0036] Step 1: The head upper limit seat 202 and the tail upper limit seat 302 are not installed first. The UHV bushing is first lifted horizontally to the top of the packaging box, and the UHV bushing is placed in the packaging box with the oil side of the lower end of the bushing flange as the base point. After the bushing falls, the tail is engaged with the first tail lower limit groove 3031 and the second tail lower limit groove 3032 on the tail lower limit seat 303, and the bushing head falls into the head lower limit groove 2034 of the head lower limit seat 203.

[0037] Step 2: Adjust the auxiliary limit plate 2031 on the lower limit seat 203 of the head until it is in close contact with the head of the casing. After the auxiliary limit plate 2031 is adjusted into place, the adjusting nuts at both ends of the adjusting bolt 2032 clamp it and fix it on the mounting frame 2033, thereby locking the position of the adjusting bolt 3023 and the auxiliary limit plate 2031 thereon. At this time, the auxiliary limit plate 2031 cooperates with the limiting table formed between the first tail lower limit groove 3031 and the second tail lower limit groove 3032 to limit the forward and backward displacement of the UHV casing.

[0038] Step three: install the two ends of the head upper limit seat 202 on the corresponding head screw 201, install the two ends of the tail upper limit seat 302 on the corresponding tail screw 301, and adjust the height so that the head upper limit seat 202 and the head lower limit seat 203 cooperate to clamp and limit the up and down displacement of the UHV bushing head, and the tail upper limit seat 302 and the tail lower limit seat 303 cooperate to clamp and limit the up and down displacement of the UHV bushing tail. After the installation is completed, nuts are respectively installed on the upper ends of the head screw 201 and the upper ends of the tail screw 301 to achieve fixation.

[0039] Step 4: Install the limit frame 1. The sleeve has a large self-weight and a great front-to-back inertia force during transportation. In order to further ensure transportation safety and prevent the sleeve from being displaced front-to-back during transportation, the utility model adds a limit frame 1 for limiting the front-to-back position of the sleeve at both ends of the packaging box. In this embodiment, the limit frame 1 is a wooden frame for easy installation on the packaging box. During installation, the side beams 103 on both sides are first fixed to the packaging box by nails, and then the two ends of the limit beam 101 and the two ends of the tail beam 104 are respectively fixed to the side beams 103 on the corresponding side by nails, and then the two ends of each support beam 102 are respectively fixed to the limit beam 101 and the tail beam 104 by nails.
