Description

Technical Field

[0001] This utility model relates to the field of mining transformers, and in particular to a mining transformer that is easy to move. Background Technology

[0002] In mining production, power supply is of paramount importance. Transformers, as key equipment in the power system, play a crucial role in voltage transformation and power transmission. However, traditional mining transformers have many shortcomings in terms of mobility. Due to the complex environment and relatively confined space in mines, traditional mining transformers are often difficult to move quickly and conveniently when relocation or transfer between different work areas is required. This not only increases labor and time costs but may also affect the progress and efficiency of mining production.

[0003] A search revealed Chinese Patent Publication No. CN212809975U, which discloses a mobile mining transformer that is easy to support. The transformer includes a body with two symmetrically arranged fixed plates fixedly connected to its bottom. Two symmetrically arranged fixed blocks are fixedly connected to the bottom of the two fixed plates. Rotating rods are rotatably connected to the two fixed blocks on the same side. Moving wheels are fixedly connected to the ends of the two rotating rods. Two symmetrically arranged threaded rods are rotatably connected to the opposite sidewalls of the two fixed plates, with opposite thread directions at both ends. Two symmetrically arranged threaded blocks are threaded onto the two threaded rods. This invention relates to the field of mining transformer technology and can quickly support and lift the entire mining transformer, while also reducing vibrations during operation to prevent damage to internal parts caused by the transformer's own shaking.

[0004] This device improves upon traditional mining transformers to some extent, successfully solving the problem of difficult movement and providing cushioning during transport, effectively preventing damage to components. However, the device still has the following shortcomings: First, the cushioning effect achieved through components such as damping barrels, shock-absorbing springs, and sliding plates only slows down the transmission speed of impact force but cannot disperse it. Therefore, internal transformer components are still easily damaged upon impact. Second, the device relies on wheels for long-term transformer support. When idle, the wheels provide support alone, and since they are in point contact with the ground, the device is prone to slippage and displacement, resulting in poor stability and potential safety hazards. Therefore, a more easily movable mining transformer is proposed to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 The present invention provides an embodiment of a mine transformer that is easy to move, including a support plate 1. A push handle 2 is fixedly connected to the right surface of the support plate 1. The push handle 2 is easy to grip and facilitates the movement of the device. A support component is provided on the lower surface of the support plate 1. The support component can provide support for the device and facilitate the movement of the device. A buffer component is provided inside the support plate 1. The buffer component can effectively reduce vibration and impact and can effectively protect the internal components of the machine body 4.

[0031] Reference Figures 2-3 The buffer assembly includes a fixed base 31, with a hollow cylinder 32 fixedly connected to the upper surface of the fixed base 31. The hollow cylinder 32 is sealed inside. A sealing gasket 33, made of rubber, is elastically connected to the inner wall of the hollow cylinder 32 via a compression spring 39. The sealing gasket 33 fits snugly against the inner wall of the hollow cylinder 32. A sliding rod 34 is fixedly connected to the upper surface of the sealing gasket 33. The sealing gasket 33 and the sliding rod 34 move synchronously. A circular hole 301 is formed on the upper surface of the sealing gasket 33. The diameter of the circular hole 301 is small, which can limit the airflow velocity. A fixed... Plate 38, the upper surface of which is fixed, is mounted with body 4, which is the body of the mining transformer. The buffer assembly also includes connecting rods 35, which are arranged in two sets and are symmetrically distributed on the left and right sides with the center line of the fixed seat 31. A slider 36 is slidably connected to the lower surface of the fixed plate 38, and a fixing block 37 is fixedly connected to the lower surface of the fixed plate 38. Hollow cylinder 32, compression spring 39, sealing gasket 33, and sliding rod 34 are arranged in two sets. One set is located on the fixed seat 31, and the hollow cylinder 32 in the other set is connected to the fixing block 37, and the sliding rod 34 is connected to the slider 36.

[0032] Reference Figures 1-2 The support assembly includes a turntable 51, and a threaded rod 52 is fixedly connected to the lower surface of the turntable 51. The threaded rod 52 is prior art and can be implemented by those skilled in the art. As it is prior art, it will not be described in detail in this case. The threaded rod 52 has self-locking properties. An I-beam 53 is rotatably connected to the lower surface of the threaded rod 52. A caster wheel 54 is provided on the lower surface of the I-beam 53. The caster wheel 54 is prior art and can be implemented by those skilled in the art. As it is prior art, it will not be described in detail in this case. The caster wheel 54 is self-locking.

[0033] Reference Figures 2-3 The lower surface of the fixed seat 31 is fixedly connected to the inner wall of the bottom end of the support plate 1. The sealing gasket 33 is piston-connected to the inner wall of the hollow cylinder 32. One end of the compression spring 39 is fixedly connected to the lower surface of the sealing gasket 33, and the other end of the compression spring 39 is fixedly connected to the inner wall of the bottom end of the hollow cylinder 32. When the sealing gasket 33 moves downward, it will squeeze the compression spring 39 to generate a reaction force. The fixed plate 38 is slidably connected to the inner wall of the support plate 1 and slides longitudinally. The slide rod 34 passes through and slides on the upper surface of the hollow cylinder 32. The outer wall of the slide rod 34 is made of rubber. The outer wall of the slide rod 34 fits against the hollow cylinder 32 to maintain a seal. One end of the connecting rod 35 is hinged to the right surface of the fixed seat 31, and the other end of the connecting rod 35 is hinged to the lower surface of the slider 36. When the fixed plate 38 moves closer to the support plate 1, the connecting rod 35 will be squeezed and swing, and the slider 36 will move laterally under the drive of the connecting rod 35.

[0034] Reference Figures 1-2 A handle is fixedly connected to the upper surface of the turntable 51 away from the center for easy gripping. A threaded rod 52 passes through and is threadedly connected to the upper surface of the support plate 1. When the threaded rod 52 rotates, it will move longitudinally. The I-beam plate 53 is slidably connected to the inner wall of the support plate 1. The I-beam plate 53 is set in an I-shape. Four sets of casters 54 are provided. The four sets of casters 54 are evenly distributed at the four corners of the lower surface of the I-beam plate 53. The four sets of casters 54 can stably support the device.

[0035] Working principle: When using this device, if it is necessary to move the device, rotate the turntable 51 to drive the threaded rod 52 to rotate. When the threaded rod 52 rotates, it will drive the turntable 51, the threaded rod 52, the I-beam plate 53, and the caster 54 to move downward. The caster 54 moving downward will support the device. Then, the caster 54 can be unlocked to facilitate moving the device.

[0036] During movement, the device will vibrate due to bumps. The impact force generated by the vibration will cause the fixed plate 38 to retract into the support plate 1. The moving fixed plate 38 will drive the slide rod 34 and the sealing gasket 33 to move. The air in the hollow cylinder 32 located below the sealing gasket 33 will be compressed and moved through the round hole 301 to the top of the sealing gasket 33. When the sealing gasket 33 moves, it will compress the compression spring 39 to generate a reaction force. Because the diameter of the round hole 301 is small, the airflow speed is restricted, thus achieving a damping effect. The elastic spring 39 acts as a buffer. In addition, when the fixed plate 38 moves, it will also squeeze the connecting rod 35 to make it swing. The swinging connecting rod 35 will push the slider 36 to move laterally. The laterally moving slider 36 will drive the other two sets of sliding rods 34 and sealing gaskets 33 to move, squeezing the air in the hollow cylinder 32 and compressing the spring 39. Under the transmission of the connecting rod 35, the impact force will be transmitted in three directions: left, right and up. Therefore, it can play the role of force distribution, further improving the buffering effect and providing protection for the internal parts of the machine body 4.

[0037] When moving to the designated location, first lock the caster 54, then rotate the turntable 51 in the opposite direction to drive the threaded rod 52 to reverse, thereby driving the turntable 51, threaded rod 52, I-beam plate 53, and caster 54 to move upward until the support plate 1 is in direct contact with the ground, ensuring the contact area, maintaining the stability of the device, and reducing safety hazards.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
