Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and in particular to a mutual inductor transporting device. Background Art

[0002] Instrument transformers are widely used in fields such as relay protection, electric energy metering, system monitoring and automatic control. Through instrument transformers, operators can ensure the safe, stable and efficient operation of the power system. However, with the increasing power load, small-ratio instrument transformers can no longer meet work requirements. At the same time, long-term operation of equipment will also cause the equipment to become obsolete, resulting in a large number of instrument transformer replacements for power supply companies.

[0003] In current production operations, 35kV voltage transformers and current transformers are mostly made of epoxy resin insulation materials, and each weighs 130kG. However, due to site conditions and team configuration, 35kV transformers are usually carried by two people. There is no place for hands to grab around the transformer, and there are no anti-dumping measures. The operators have to rely solely on their operating ability. During the loading and unloading of the transformer and the process of going up and down the stairs, if the two people are not coordinated or exhausted, the equipment is likely to tip over, causing equipment damage or personal injury. Summary of the invention

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-8 The present invention discloses a transformer transporting device, including a mobile platform 1, on which a lifting mechanism 2 for lifting a transformer 5 from the ground and suspending it in the air is provided, and on which a locking mechanism 3 for locking the lifting mechanism 2 after the transformer 5 is lifted to prevent the transformer 5 from falling is provided, and at least two handles 4 for holding are symmetrically provided on the top of the mobile platform 1.

[0028] According to the present invention, the mutual inductor 5 placed on the ground is lifted by the lifting mechanism 2, and then locked by the locking mechanism 3. When the road surface is flat, the mutual inductor 5 can be moved directly by pulling the mobile platform 1. During the loading and unloading of the mutual inductor 5 and the going up and down stairs, the mutual inductor 5 can be carried by holding the handle 4, which greatly ensures the safety during the carrying process, and prevents the equipment from being damaged due to the slipping of the outer shell and the tipping over of the equipment. It also eliminates personal injuries caused by problems with the carrying posture, thereby greatly improving the carrying efficiency.

[0029] In one embodiment, the mobile platform 1 includes two gantry brackets 11 and two universal wheels 12 arranged at the bottom of the gantry brackets 11. A splicing assembly 13 for splicing the two gantry brackets 11 into a whole is arranged between the two gantry brackets 11.

[0030] Such a design enables the mobile platform 1 to consist of two separate units, which can be moved from both sides of the mutual inductor 5 toward the mutual inductor 5, and then spliced ​​together into a complete whole through the splicing assembly 13, thereby facilitating the transportation of the mutual inductor 5 placed on the ground.

[0031] In one embodiment, the splicing assembly 13 includes at least one splicing seat 131 and at least one splicing strip 132 inserted into the splicing seat 131. The splicing seat 131 and the splicing strip 132 are respectively arranged on two gantry-type brackets 11. A sliding groove adapted to the splicing strip 132 is opened in the splicing seat 131. When the splicing strip 132 moves back and forth in the sliding groove, the two gantry-type brackets 11 approach or move away from each other.

[0032] With this design, maintenance personnel only need to operate the two gantry brackets 11 to move toward the mutual inductor 5 to complete the assembly of the mobile platform 1, so that the gantry brackets 11 can maintain a stable position after being subjected to force. After the mutual inductor 5 is moved, the gantry brackets 11 can be pulled outward to quickly complete the disassembly operation of the mobile platform 1.

[0033] In one embodiment, the lifting mechanism 2 is composed of two lever mechanisms, which are respectively arranged on two gantry supports 11, and the lever mechanism is composed of two symmetrically arranged power arms 21 and two resistance arms 22, the power arms 21 and the resistance arms 22 are both rotatably connected to the gantry supports 11, and the axis of the rotation shaft of the power arm 21 coincides with the axis of the rotation shaft of the resistance arm 22, and the two lever mechanisms do not interfere with each other when rotating;

[0034] When the power arm 21 rotates toward the side away from the mutual inductor 5 , the resistance arm 22 rotates upward, and the distance between the resistance arms 22 on the same lever mechanism is smaller than the maximum width of the mutual inductor 5 .

[0035] With this design, after the resistance arm 22 moves to below the skirt of the transformer 5, by utilizing the lever principle, when two maintenance personnel simultaneously press down the power arm 21, the transformer 5 placed on the ground can be lifted up through the resistance arm 22, thereby achieving a lifting effect.

[0036] In the specific implementation, in order to reduce the labor intensity of maintenance personnel, the length of the power arm 21 is greater than the length of the resistance arm 22. In order to prevent the lifting mechanism 2 from damaging the skirt of the transformer 5 during the lifting process, rubber material needs to be wrapped at the contact position with the transformer 5.

[0037] In one embodiment, the resistance arm 22 includes a horizontal section 221 rotatably disposed on the gantry bracket 11, and a limit section 222 is disposed on the horizontal section 221 for preventing the power arm 21 from rotating toward a side away from the transformer 5. An inclined section 223 is disposed at one end of the horizontal section 221 away from the power arm 21. The horizontal section 221 is located at the top of the splicing seat 131 and the splicing strip 132. When the horizontal section 221 is in a natural state, the horizontal section 221 is parallel to the ground and the inclined section 223 is inclined toward the ground.

[0038] Such a design enables the mutual inductor 5 to be supported by the inclined section 223 on the resistance arm 22 after the mutual inductor 5 is lifted to a certain height, thereby improving the support stability.

[0039] In one embodiment, the locking mechanism 3 includes a sleeve 31, which is threadedly mounted on the inclined section 223 of one of the lever mechanisms. A spring 32 is disposed in the sleeve 31, and a bayonet 33 penetrating the inclined section 223 is disposed at one end of the spring 32 close to the mutual inductor 5. When the sleeve 31 rotates, the bayonet 33 rotates synchronously.

[0040] A plurality of slots 34 matching with the bayonet 33 are formed on the inclined section 223 of the other lever mechanism, and an inclined surface assisting the bayonet 33 to be engaged with the bayonet 33 is provided at one end of the bayonet 33 close to the mutual inductor 5 .

[0041] With such a design, when the inclined section 223 rotates to be parallel to the ground, the maintenance personnel on both sides continue to push the gantry bracket 11 close to the mutual inductor 5, so that the latch 33 is locked into the latch slot 34 during the movement. At this time, pulling the mobile platform 1 will not cause the mobile platform 1 to separate, so that the maintenance personnel can transport the mutual inductor 5 by pulling the power arm 21. After the transportation is completed, by rotating the sleeve 31 180 degrees, the inclined surface of the latch 33 is reversed, so that the gantry bracket 11 can be pulled to separate the mobile platform 1.

[0042] In one embodiment, the locking mechanism 3 also includes a stress bar 35 for bearing the downward pressure of the mutual inductor 5. The stress bar 35 is arranged on the inclined section 223 of one of the lever mechanisms, and one end of the stress bar 35 is flush with the end of the inclined section 223 away from the horizontal section 221. A slot 36 adapted to the stress bar 35 is provided on the inclined section 223 of the other lever mechanism.

[0043] Such a design ensures that the latch 33 only needs to bear a small amount of downward pressure from the transformer 5, thereby ensuring safety.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In addition, "plurality" means two or more.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
