Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation. More specifically, the utility model relates to an auxiliary lifting device for transformer installation. Background Art

[0002] A transformer is an electrical device used to change the alternating voltage and is widely used in power transmission, electronic equipment and various industrial applications. It is an indispensable part of modern power systems and electronic equipment. At present, for safety reasons, the installation height of transformers is usually set high on utility poles away from the ground. Therefore, during the installation or maintenance of transformers, aerial work vehicle devices such as scissor lifts are needed to participate in the lifting of workers and replacement equipment. However, in the actual use process, there are still some problems. For example, when the personnel and equipment are lifted to an appropriate height but the lateral position is offset, it is difficult for the stable lift to adjust the position. At this time, the workers need to move the transformer equipment to ensure its installation in the correct position. However, since the workers are at a high place and lack a leverage point, this increases the risk of maintenance or installation operations. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides an auxiliary lifting device for transformer installation to solve the problem that in the prior art, workers at high places need to move transformer equipment, which increases the risk of maintenance or installation operations due to the lack of a leverage point.

The bottom of the movable block is fixedly installed on the top of the bottom plate. The bottom of the frame plate is fixedly installed on the top of the bottom plate. The bottom of the vertical plate is fixedly installed on the top of the bottom plate.

One end of the movable box is slidably installed on the inner surface of the fixed box, and the other end is slidably installed on the inner surface of the auxiliary box. The inner surface of the end of the movable box close to the fixed box is threadedly connected to the outer surface of the first screw rod. The second motor is arranged inside the end of the movable box close to the auxiliary box. The output end of the second motor is fixedly installed on the side end of the second screw rod. The outer surface of the second screw rod is threadedly connected to the bottom end of the middle part of the supporting plate. The second motor is electrically connected to the controller.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] In the above solution, by setting up structures such as an auxiliary installation component, when the staff at a high place finds that the accurate target position has not been reached, the motor 1 can be controlled to rotate through the controller, so that the connected screw rod 1 rotates, driving the horizontally moving mechanism connected by threads to move up and down, thereby correcting the position of the transformer placed inside the supporting plate in the vertical direction. At the same time, the motor 2 can also be controlled to rotate, so that the connected screw rod 2 rotates, driving the supporting plate connected by threads to move left and right, thereby correcting the position of the transformer placed inside the supporting plate in the horizontal direction, so that the transformer is moved to the accurate installation position. At this time, the fastening of the transformer is loosened and it is installed. Therefore, through the above structure, the transformer equipment at a high place can be easily corrected in position, making it meet the expected installation target. Moreover, it can avoid dangerous situations during the process of the operators at high altitude carrying and adjusting the equipment, improving the operation safety.

[0017] In the above solution, by setting up a safety protection component, during the process of the platform lifting and lowering through the lifting component, multiple infrared sensors arranged at the bottom of the platform will emit infrared beams towards the bottom in real time. Under the reflection of the reflector, the multiple vertically emitted infrared beams will be received by the receivers of the infrared sensors again. During this process, when an object is inserted into them, it will cause the time of some infrared sensors emitting and receiving infrared beams to be different from that of the other infrared sensors. The controller electrically connected to the infrared sensors responds quickly to this information feedback difference and controls the air cylinder to stop extending or contracting, so that the platform brakes emergently, avoiding the telescopic frame being affected by external objects during the lifting process of the device and causing damage to the device or the inserted object.

[0038] The working process of the present utility model is as follows:

[0039] First, the staff places the transformer inside the supporting plate 62 at a low position and controls the electric push rod 63 to extend, pushing the connected clamping plate 64 to fasten the transformer to a certain extent. Then, the staff is at the top of the platform 3 and closes the movable door panel of the guardrail 4. After that, the controller 5 is used to control the cylinder 23 to contract, so that one end of the telescopic frame 24 rotates along the middle of the movable block 20, and the other end moves horizontally along the middle of the frame plate 21, causing the telescopic frame 24 to extend and pushing the platform 3 installed on the top to move upward. Finally, the staff and the transformer are lifted to an appropriate height;

[0040] When the staff at a high position finds that the accurate target position has not been reached, the controller 5 can be used to control the rotation of the first motor 601, so that the connected first screw 602 rotates, driving the horizontally moving mechanism 61 connected by threads to move up and down, thereby correcting the position of the transformer placed inside the supporting plate 62 in the vertical direction. At the same time, the second motor 611 can also be controlled to rotate, so that the connected second screw 612 rotates, driving the supporting plate 62 connected by threads to move left and right, thereby correcting the position of the transformer placed inside the supporting plate 62 in the horizontal direction, so that the transformer is moved to the accurate installation position. At this time, the fastening of the transformer is loosened and it is installed. Thus, through the above structure, the transformer equipment at a high position can be easily corrected in position, making it meet the expected installation target. Moreover, it can avoid dangerous situations during the process of the operators at high altitude carrying and adjusting the equipment, improving the operation safety;

[0041] During the lifting process of the platform 3 by the lifting assembly 2, multiple infrared sensors 71 provided at the bottom of the platform 3 will emit infrared light beams towards the bottom in real time. Under the reflection of the reflector 72, the multiple vertically emitted infrared light beams will be received again by the receivers of the infrared sensors 71. During this process, when an object is inserted, it will cause the time for some of the infrared sensors 71 to emit and receive infrared light beams to be different from that of the remaining infrared sensors 71. The controller 5 electrically connected to the infrared sensors 71 responds quickly to this difference in information feedback and controls the cylinder 23 to stop extending or contracting, so that the platform 3 is emergently braked, avoiding damage to the device or the inserted object due to the influence of external objects on the telescopic frame 24 during the lifting process of the device.
