Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant equipment technology, and in particular to a large voltage transformer transport device. Background Technology

[0002] In nuclear power plants, large voltage transformers are bulky and heavy. Due to space constraints, forklifts cannot access some areas. When large voltage transformers need replacement, they are typically transported by handcarts. However, these handcarts require manual pushing, and the risk of tipping over is high during transport due to factors such as personnel strength and coordination. Tipping over can easily damage the transformer, so personnel must support it during transport to ensure its safe arrival at its destination. This method of transportation suffers from low efficiency, high manpower consumption, and poor safety. Utility Model Content

[0033] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] In the following description, it should be understood that the orientations or positional relationships indicated by terms such as "front," "rear," "up," "down," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" are based on the orientations or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or component referred to must have a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] This invention provides a large voltage transformer transport device, which is applied in nuclear power plants to help workers transport large voltage transformers in some narrow spaces within the plant, thereby improving the transport efficiency and safety of the large voltage transformers during the transport process.

[0036] Please see Figure 1 , Figure 2 The large voltage transformer transport device may include a load-bearing plate 1, a guardrail 2, a drive wheel assembly 3, a steering wheel assembly 4, a wheel drive mechanism 5, a control module 6, and an energy storage module 7.

[0037] The load-bearing plate 1 is used to support the voltage transformer. Since large voltage transformers are heavy, the load-bearing plate 1 is preferably a rectangular plate made of a strong metal such as steel.

[0038] like Figure 1 As shown, guardrail 2 is installed on top of the load-bearing plate 1. Guardrail 2 is used to prevent the voltage transformer from tipping over during transportation. Specifically, guardrail 2 is circumferentially installed around the top of the load-bearing plate 1, and workers can use a crane to hoist large voltage transformers into the guardrail 2 on site.

[0039] In some embodiments, such as Figure 3 As shown, the top of the load-bearing plate 1 can be provided with multiple mounting holes 11, and the guardrail 2 can be in the shape of a square tube (i.e., a square tube body; please refer to the specific shape). Figure 3 The guardrail 2 has multiple protruding structures 21 at the opening near the top of the load-bearing plate 1. Each protruding structure 21 corresponds one-to-one with a plurality of mounting holes 11, allowing each protruding structure 21 to be detachably inserted into each mounting hole 11. In this embodiment, before hoisting the large voltage transformer, workers can first disassemble the guardrail 2 during transformer transportation, then hoist the large voltage transformer to the top of the load-bearing plate 1, and then reinstall the guardrail 2 on top of the load-bearing plate 1, ensuring the large voltage transformer is placed inside the guardrail 2. This easily understandable method reduces the difficulty for workers in hoisting the large voltage transformer into the guardrail 2.

[0040] Furthermore, such as Figure 4As shown, each protruding structure 21 may include a cylindrical structure 211 that can be inserted into the mounting hole 11 and a limiting structure 212 located in the middle of the cylindrical structure to limit the insertion depth of the cylindrical structure 211.

[0041] In some embodiments, such as Figure 3 As shown, the large voltage transformer transport device may also include a push-pull mechanism 8 mechanically connected to the guardrail 2. The push-pull mechanism 8 is used when the energy storage module 7 is without power or when the drive wheel assembly 3 cannot be electrically driven normally due to a fault (such as a motor failure), allowing workers to manually push and pull the transport device to its destination.

[0042] In some embodiments, such as Figure 3 As shown, guardrail 2 can be a grid-like guardrail, which helps to reduce the weight of the transport device and reduce the load on the wheel drive mechanism 5 or manual pushing and pulling.

[0043] like Figure 2 As shown, the drive wheel assembly 3 is located at the bottom of the load-bearing plate 1.

[0044] In some embodiments, such as Figure 2 As shown, the drive wheel assembly 3 may include a rotating shaft 31 and two first wheels 32. The rotating shaft 31 is located near the first end 12 of the load-bearing plate 1, and is mechanically connected to the two first wheels 32 via two bearings 33 fixed to the bottom of the load-bearing plate 1. The wheel drive mechanism 5 is drively connected to the rotating shaft 31, and can drive the rotating shaft 31 to rotate, thereby driving the two first wheels 32 to rotate forward or backward, so as to control the forward or backward movement of the large voltage transformer transport device.

[0045] In some embodiments, each first wheel 32 is also provided with a brake pad. The function of the brake pad is to lock the two first wheels 32 when hoisting the transformer, so as to prevent the large voltage transformer transport device from being accidentally moved during the hoisting process and reduce the risk of damage to the transformer due to misoperation.

[0046] like Figure 2 As shown, the steering wheel assembly 4 is located at the bottom of the load-bearing plate 1.

[0047] In some embodiments, such as Figure 2As shown, the steering wheel assembly 4 may include a crossbar 41, two steering arms 42, and two second wheels 43. The first ends of the two steering arms 42 are mechanically connected to the two second wheels 43 one-to-one. The two steering arms 42 are close to the second end 13 of the load-bearing plate 1 (the second end 13 of the load-bearing plate 1 is opposite to the first end 12) and are rotatably connected to the bottom of the load-bearing plate 1. The two steering arms 42 are also slidably connected to the crossbar 41. The crossbar 41 is connected to the wheel drive mechanism 5. The wheel drive mechanism 5 can drive the crossbar 41 to move left and right, so as to drive the crossbar 41 to push the two steering arms 42 to rotate simultaneously in the same direction (clockwise or counterclockwise), thereby driving the two second wheels 43 to turn, so as to control the left or right turn of the transport device.

[0048] In some embodiments, such as Figure 2 As shown, each steering arm 42 may include a first arm 421 and a second arm 422. The first end of the first arm 421 is mechanically connected to a second wheel 43 without interfering with the rotation of the second wheel 43. The second end of the first arm 421 is close to the second end 13 of the load-bearing plate 1 and rotatably connected to the bottom surface of the load-bearing plate 1. The second end of the first arm 421 is also mechanically connected to the second arm 422. The second arm 422 has a through groove 423 in its middle. (The text repeats itself here.) Figure 5 As shown, the crossbar 41 may include a bar body and two cylindrical structures 411 that protrude outward from both ends of the bar body. The two cylindrical structures 411 pass through the through slots 423 of the two second arm bars 422 one to one, and can slide in the corresponding through slots 423.

[0049] In this embodiment, the first boom 421 and the second boom 422 can be an integrated structure. The connection between the first boom 421 and the second boom 422 can be rotatably connected to the bottom of the load-bearing plate 1 via screws, allowing the steering arm 42 to rotate clockwise or counterclockwise. The crossbar 41 will move laterally left and right under the drive of the wheel drive mechanism 5. Please refer to [link to relevant documentation]. Figure 2 When the crossbar 41 moves to the left, it will push the left steering arm 42 to rotate counterclockwise and pull the right steering arm 42 to rotate counterclockwise as well, thereby realizing the left turn control of the large voltage transformer transport device. Similarly, when the crossbar 41 moves to the right, it will drive both steering arms 42 to rotate clockwise at the same time, thereby realizing the right turn control of the large voltage transformer transport device.

[0050] like Figure 2 As shown, the second end of the load-bearing plate 1 is also provided with concave structures 23 on both sides to prevent the load-bearing plate 1 from interfering with the steering of the two second wheels 43.

[0051] like Figure 2As shown, the wheel drive mechanism 5 is mechanically connected to the load-bearing plate 1, and the wheel drive mechanism 5 is connected to the drive wheel assembly 3 and the steering wheel assembly 4 via transmission. The wheel drive mechanism 5 is used to drive the drive wheel assembly 3 to rotate and drive the steering wheel assembly 4 to turn.

[0052] In some embodiments, such as Figure 2 As shown, the wheel drive mechanism 5 may include a first motor 51, a first transmission box 52, a second motor 53, and a second transmission box 54. The first motor 51 and the first transmission box 52 are mechanically connected to the first end 12 of the load-bearing plate 1, and the first transmission box 52 is also drive-connected to the first motor 51 and the rotating shaft 31. The second motor 53 and the second transmission box 54 are disposed near the second end 13 of the load-bearing plate 1, and the second transmission box 54 is also drive-connected to the second motor 53 and the crossbar 41.

[0053] In this embodiment, the first transmission box 52 and the second transmission box 54 can be existing gear transmission boxes. The first transmission box 52 meshes with the rotating shaft 31 to drive the rotating shaft 31 to rotate; the second transmission box 54 meshes with the drive crossbar 41 to drive the crossbar 41 to move left and right.

[0054] like Figure 6 As shown, the control module 6 is electrically connected to the wheel drive mechanism 5, and the control module 6 is used to control the wheel drive mechanism 5.

[0055] In some embodiments, such as Figure 6 As shown, the control module 6 may include a main control unit 61 electrically connected to the wheel drive mechanism 5, and a wireless communication unit 62 electrically connected to the main control unit 61 for communicating with a client terminal to obtain control commands for the transport vehicle.

[0056] In this embodiment, the main control unit 61 may include an existing motor drive control module, which can drive the first motor 51 and the second motor 53 to rotate forward or in reverse, respectively. The wireless communication unit 62 may be a Bluetooth communication module or a WiFi communication module, and its main function is to receive transport vehicle control commands from a client terminal (such as a staff member's mobile phone) to control the first motor 51 and the second motor 53 to rotate forward or in reverse, thereby controlling the transport device to move forward, backward, and turn left or right. It should be noted that the computer program for operating the transport device using a mobile phone or other client terminal in this embodiment should refer to existing technologies (such as technologies related to operating the forward, backward, and turning movements of a transport vehicle using a mobile phone).

[0057] The energy storage module 7 is electrically connected to the wheel drive mechanism 5 and the control module 6 to supply power to the wheel drive mechanism 5 and the control module 6.

[0058] In some embodiments, such as Figure 6As shown, the energy storage module 7 may include a battery module 71, a power display module 72, and a charging module 73. The battery module 71 is electrically connected to the wheel drive mechanism 5, the control module 6, the power display module 72, and the charging module 73.

[0059] Specifically, battery module 71 may include multiple lithium batteries, which are electrically connected in series and parallel to form a battery pack. The battery pack can output 41V to 52V DC power to the wheel drive mechanism 5 and control module 6. The power display module 72 can be an existing battery power monitoring module capable of displaying the battery pack's power level in real time; no limitation is imposed here. The charging module 73 can be an existing lithium battery charging module capable of charging the battery pack using AC power; no limitation is imposed here.

[0060] In some embodiments, such as Figure 6 As shown, the energy storage module 7 may also include a circuit breaker Q1, a circuit breaker SW1, and a manual control panel 63. The positive output terminal of the battery module 71 is electrically connected to the main control unit 61 and the power display module 72 via the circuit breaker Q1 and the circuit breaker SW1. The circuit breaker Q1 can be an existing overcurrent protector, used to disconnect when the battery module 71 outputs overcurrent or overload. The manual control panel 63 is electrically connected to the main control unit 61. The manual control panel 63 may include a first switch K1, a second switch K2, and a third switch K3. The first switch K1, the second switch K2, and the third switch K3 are electrically connected to the main control unit 61, respectively. The operator can control the forward, backward, and left / right turns of the transport device by operating the first switch K1, the second switch K2, and the third switch K3.

[0061] In some embodiments, such as Figure 1 As shown, the large voltage transformer transport device may also include a fixing frame 9 that is mechanically connected to the first end 12 of the load-bearing plate 1. The fixing frame 9 is used to fix the control module 6, the first motor 51 and the first transmission box 52.

[0062] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
