Technical Field

[0001] This utility model relates to the field of power supply vehicle technology, specifically to hoisting devices, power supply containers, and power supply vehicles. Background Technology

[0002] With the needs of national construction and development, special-purpose vehicles have become important transportation and operational equipment in economic construction, and have a promising future. In recent years, due to the increased construction and investment in my country's power, telecommunications, mobile, and network communications sectors, power supply vehicles are designed as live-line emergency work vehicles to meet the needs of these industries. They can be used for emergency power supply work in communications, telecommunications, coal mines, and oil fields, playing a particularly important role in power outage repair and power supply during emergencies. To address the problem of low vehicle turnover efficiency caused by slow or even difficult recharging when the power supply vehicle's battery is depleted, existing technologies employ the method of hoisting and swapping power supply containers to improve the turnover efficiency of power supply vehicles. However, existing hoisting devices occupy a large space on the power supply vehicle, easily leading to the vehicle being too wide. Utility Model Content

[0003] In view of this, the present invention provides a hoisting device, a power supply container, and a power supply vehicle to solve the problem that existing hoisting devices occupy a large space on the power supply vehicle, which easily leads to the power supply vehicle being too wide.

[0004] In a first aspect, this utility model provides a lifting device, which is installed on the base of a power supply container, comprising: a fixing structure having an insertion hole, the fixing structure being installed on the base, and a limiting space being formed between the end of the fixing structure having the insertion hole and the base; and a lifting device, which is inserted into the insertion hole and rotatably configured, the lifting device having an unlocked position and a locked position, in the unlocked position the lifting device is located outside the limiting space, and in the locked position a portion of the lifting device extends into the limiting space.

[0005] Beneficial effects: The fixed structure is installed on the base of the power container. When the power container needs to be lifted, the spreader is inserted through the insertion hole. At this time, the spreader is outside the limiting space and in the unlocked position. Then, by rotating the spreader, part of the spreader is extended into the limiting space to limit the spreader along the axis and fix the position of the spreader and the fixed structure, thus keeping the spreader in the locked position. The spreader can then be used for lifting. After use, the spreader is rotated to the unlocked position and can be removed. Therefore, the space occupied by the lifting device on the power vehicle can be reduced, avoiding the problem of the power vehicle being too wide.

[0006] In one optional embodiment, the lifting device includes a lifting rod and a limiting plate. The limiting plate is connected to the peripheral wall of the lifting rod and located between the two ends of the lifting rod to divide the lifting rod into a plug-in section and a lifting section. The plug-in section is adapted to be inserted into the plug-in hole. The limiting plate has a material shortage area and a limiting area formed circumferentially. In the unlocked position, the material shortage area is opposite to the limiting space. In the locked position, the limiting area extends into the limiting space; and / or,

[0007] The hoisting device further includes a connector, which is detachably connected to the lifting device and the fixing structure, and is adapted to fix the lifting device in the locking position.

[0008] Beneficial effects: By forming a material shortage point and a limiting point along the circumference of the limiting plate, the limiting plate can be inserted into or moved out of the limiting space by rotating the lifting device, so that the lifting device can switch between the unlocked position and the locked position. The overall structure of the lifting device is simple and easy to use.

[0009] Connect and secure the lifting device to the fixed structure using connectors to limit the device circumferentially, thus keeping it in the locked position. The device can then be used for lifting. After use, remove the connectors and rotate the device to the unlocked position to remove it.

[0010] In one alternative embodiment, the lifting device further includes an end plate connected to one end of the lifting section away from the limiting plate, wherein at least a portion of the orthographic projection of the end plate is located outside the orthographic projection of the lifting rod on a projection plane perpendicular to the axial direction of the lifting rod.

[0011] Beneficial effects: By setting end plates, the slings located in the hoisting section can be blocked during hoisting, preventing the slings from slipping and ensuring the safety of hoisting.

[0012] In one optional embodiment, the fixing structure has a first hole at one end where the insertion hole is located, and the limiting plate has a second hole. In the locked position, the first hole and the second hole are connected, and the connector passes through both the first hole and the second hole.

[0013] Beneficial effects: After the limiting plate is rotated to the locked position, the connection and fixation of the lifting device and the fixed structure are achieved by the connecting piece cooperating with the first hole and the second hole. The fixing method is simple and easy to operate.

[0014] In one alternative embodiment, the first orifice and / or the second orifice are elongated orifices.

[0015] Beneficial effects: By setting the first hole and / or the second hole to be elongated, it is easy to connect the first hole and the second hole, thereby facilitating the installation of the connector.

[0016] In one optional embodiment, the fixing structure includes a mounting base and a cylindrical body, the mounting base being connected to the base, the cylindrical body being disposed within the mounting base, and the insertion hole being formed inside the cylindrical body.

[0017] Beneficial effects: By using the mounting bracket to fix the cylinder to the base, the structural stability of the cylinder is improved, thereby improving the reliability of the cooperation between the lifting device and the fixed structure.

[0018] In one optional embodiment, the mounting base includes a top plate, a bottom plate, and a reinforcing plate, wherein the top plate and the bottom plate are disposed opposite to each other, and the reinforcing plate is connected between the top plate and the bottom plate; and / or,

[0019] A force transmission plate is provided between the outer wall of the cylinder and the mounting base.

[0020] Beneficial effects: By using the top plate, bottom plate and reinforcing plate to form the mounting base, the overall weight of the fixed structure is reduced while ensuring the structural strength of the mounting base, thereby ensuring the lightweight of the power container.

[0021] By using a force transmission plate to connect the cylinder and the mounting base, the cylinder is subjected to more even force during hoisting, thus improving the structural stability of the cylinder within the mounting base.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a lifting device 10 is provided, which is disposed on the base 20 of a power supply container, including: a fixing structure 1 with a plug-in hole 11, the fixing structure 1 being disposed on the base 20, and a limiting space 2 being formed between the end of the fixing structure 1 with the plug-in hole 11 and the base 20; and a lifting device 3, which is inserted into the plug-in hole 11 and is rotatably disposed, the lifting device 3 having an unlocked position and a locked position, in the unlocked position the lifting device 3 is located outside the limiting space 2, and in the locked position a portion of the lifting device 3 extends into the limiting space 2.

[0039] Using the lifting device 10 of this embodiment, the fixing structure 1 is installed on the base 20 of the power container. When the power container needs to be lifted, the lifting tool 3 is inserted through the insertion hole 11. At this time, the lifting tool 3 is outside the limiting space 2 and is in the unlocked position. Then, by rotating the lifting tool 3, part of the lifting tool 3 is extended into the limiting space 2 to limit the lifting tool 3 along the axial direction and fix the position of the lifting tool 3 and the fixing structure 1, so that the lifting tool 3 is kept in the locked position and can be used for lifting. After use, the lifting tool 3 is rotated to the unlocked position and can be removed. Therefore, the space occupied by the lifting device 10 on the power vehicle can be reduced, and the problem of the power vehicle being too wide can be avoided.

[0040] Furthermore, in one embodiment, the lifting device 10 further includes a connector, which is detachably connected to the lifting device 3 and the fixing structure 1, and is adapted to fix the lifting device 3 in a locked position. The connector is used to connect and fix the lifting device 3 and the fixing structure 1 to limit the lifting device 3 circumferentially, thereby keeping the lifting device 3 in the locked position, allowing lifting operations to be performed. After use, the connector is removed, and the lifting device 3 is rotated to the unlocked position to dismantle the lifting device 3.

[0041] It is worth noting that in related technologies, a lifting rod 31 is provided on the base 20 of the power container. The lifting rod 31 extends along the width direction of the power container and passes through both sides of the base 20 along the width direction. Therefore, the lifting rod 31 is always installed on the base 20, which increases the overall width of the power container and easily leads to the problem of exceeding the width limit. In this embodiment, the spreader 3 is detachable. When lifting is required, the spreader 3 is installed on the fixed structure 1, and the base 20 is used to limit the spreader 3 axially, while the connecting parts are used to limit the spreader 3 circumferentially, ensuring the stable installation of the spreader 3. When lifting is not required, the spreader 3 can be removed from the fixed structure 1, reducing the overall width of the power container and avoiding the problem of exceeding the width limit.

[0042] Furthermore, in related technologies, to reduce the overall weight of the power container, the boom 31 is usually made into a hollow bar, which weakens the structural strength of the boom 31, making it prone to bending and deformation, and posing a safety risk during lifting. In this embodiment, however, the spreader 3 does not need to extend along the entire width of the power container. Therefore, the spreader 3 only needs a shorter length, which significantly reduces its weight. This allows the spreader 3 to adopt a solid structure, improving its structural strength, avoiding deformation and failure, and ensuring the safety of the lifting process.

[0043] It is worth noting that the end of the fixed structure 1 with the insertion hole 11 is the end where the hole of the insertion hole 11 is located, which is also the end where the lifting device 3 is allowed to be inserted.

[0044] In one embodiment, such as Figures 2 to 8 As shown, the lifting device 3 includes a lifting rod 31 and a limiting plate 32. The limiting plate 32 is connected to the peripheral wall of the lifting rod 31 and is located between the two ends of the lifting rod 31, dividing the lifting rod 31 into a insertion section 311 and a lifting section 312. The insertion section 311 is adapted to be inserted into the insertion hole 11. The limiting plate 32 has a material shortage point 321 and a limiting point 322 formed circumferentially. In the unlocked position, the material shortage point 321 is opposite to the limiting space 2. In the locked position, the limiting point 322 extends into the limiting space 2. By forming the material shortage point 321 and the limiting point 322 circumferentially on the limiting plate 32, the limiting plate 32 can be inserted into or removed from the limiting space 2 by rotating the lifting device 3, so that the lifting device 3 can switch between the unlocked and locked positions. The overall structure of the lifting device 3 is simple and easy to use.

[0045] It should be noted that, as Figure 8 As shown, in the locked position, the insertion segment 311 is inserted into the insertion hole 11, and the limiting plate 32 and the hoisting segment 312 are both located outside the insertion hole 11. The side of the limiting plate 32 near the insertion segment 311 is abutted against the end face of the fixed structure 1 where the insertion hole 11 is opened.

[0046] It is worth noting that, such as Figure 2 As shown, in this embodiment, a limiting plate 32 is formed by cutting off the outer circular portion of the circular plate. The cut-off location is the material shortage point 321, and the remaining portion can be used as a limiting point 322. Preferably, the limiting point 322 is located opposite to the material shortage point 321. That is, by rotating the limiting plate 32 by 180°, the lifting device 3 can switch between the unlocked position and the locked position.

[0047] In one embodiment, such as Figure 2As shown, the lifting device 3 also includes an end plate 33, which is connected to the end of the lifting section 312 away from the limiting plate 32. On the projection plane perpendicular to the axis of the lifting rod 31, at least a portion of the orthographic projection of the end plate 33 is located outside the orthographic projection of the lifting rod 31. By setting the end plate 33, the sling located in the lifting section 312 can be blocked during lifting, preventing the sling from slipping and ensuring the safety of the lifting.

[0048] It is worth noting that, on the projection plane perpendicular to the axis of the boom 31, at least a portion of the orthographic projection of the end plate 33 lies outside the orthographic projection of the boom 31, that is, at least a portion of the outer periphery of the end plate 33 extends beyond the outer periphery of the insertion section 311. Specifically, as... Figure 2 As shown, in this embodiment, the boom 31 is a cylindrical rod, and the end plate 33 is a circular plate with a diameter larger than that of the boom 31.

[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixed structure 1 has a first hole 12 at one end with the insertion hole 11, and the limiting plate 32 has a second hole 323. In the locked position, the first hole 12 and the second hole 323 are connected, and the connecting piece passes through both the first hole 12 and the second hole 323. After the limiting plate 32 is rotated to the locked position, the connecting piece cooperates with the first hole 12 and the second hole 323 to connect and fix the lifting device 3 and the fixed structure 1. The fixing method is simple and easy to operate.

[0050] Specifically, in this embodiment, the connector is a bolt. In the locked position, the connector is fastened to the first hole 12 and the second hole 323 and connects the limiting plate 32 and the fixing structure 1.

[0051] In one embodiment, the first hole 12 and / or the second hole 323 are elongated holes. By setting the first hole 12 and / or the second hole 323 to be elongated, it is easier to connect the corresponding first hole 12 and the second hole 323, thereby facilitating the installation of the connector.

[0052] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the first hole 12 is an elongated hole, and the second hole 323 is a circular hole. Of course, in other alternative embodiments, the second hole 323 can be set as an elongated hole, and the first hole 12 can be set as a circular hole; or, both the first hole 12 and the second hole 323 can be set as elongated holes.

[0053] In one embodiment, such as Figure 1As shown, the fixing structure 1 includes a mounting base 13 and a cylindrical body 14. The mounting base 13 is connected to the base 20, and the cylindrical body 14 is disposed inside the mounting base 13. An insertion hole 11 is formed inside the cylindrical body 14. The cylindrical body 14 is fixedly installed on the base 20 using the mounting base 13, which improves the structural stability of the cylindrical body 14 and thus improves the reliability of the cooperation between the lifting device 3 and the fixing structure 1.

[0054] It is worth noting that, in this embodiment, as Figure 1 As shown, the first hole 12 is opened on one end face of the cylinder 14, and in the locked position, the limiting plate 32 is abutted against one end face of the cylinder 14.

[0055] Furthermore, in one embodiment, such as Figure 1 As shown, the mounting base 13 includes a top plate 131, a bottom plate 132, and a reinforcing plate 133. The top plate 131 and the bottom plate 132 are arranged at intervals relative to each other, and the reinforcing plate 133 connects the top plate 131 and the bottom plate 132. The mounting base 13 is formed by the top plate 131, the bottom plate 132, and the reinforcing plate 133. While ensuring the structural strength of the mounting base 13, the overall weight of the fixing structure 1 is reduced, thereby ensuring the lightweight of the power supply container.

[0056] Specifically, in one embodiment, such as Figure 1 As shown, several reinforcing plates 133 are spaced apart between the top plate 131 and the bottom plate 132, and the cylinder 14 is located between adjacent reinforcing plates 133.

[0057] Furthermore, in one embodiment, such as Figure 1 As shown, a force transmission plate 15 is provided between the outer wall of the cylinder 14 and the mounting base 13. By using the force transmission plate 15 to connect the cylinder 14 and the mounting base 13, the cylinder 14 is subjected to more uniform force during hoisting, thereby improving the structural stability of the cylinder 14 within the mounting base 13.

[0058] Specifically, in one embodiment, such as Figure 1 As shown, the cylinder 14 is connected to the side of the bottom plate 132 facing the top plate 131, and the cylinder 14 and the top plate 131 are connected by a force transmission plate 15. It is worth noting that when connecting the cylinder 14 to the bottom plate 132, there may be a gap between the cylinder 14 and the top plate 131. The force transmission plate 15 is used to connect the cylinder 14 and the top plate 131, improving the load-bearing capacity of the cylinder 14. Of course, when the cylinder 14 is positioned between the top plate 131 and the bottom plate 132, there may be no gap between the cylinder 14 and the bottom plate 132, or between the cylinder 14 and the top plate 131. In this case, the cylinder 14 and the bottom plate 132 can be directly connected.

[0059] Furthermore, the reinforcing plate 133 and the top plate 131, the reinforcing plate 133 and the bottom plate 132, the cylinder 14 and the bottom plate 132, the force transmission plate 15 and the cylinder 14, and the force transmission plate 15 and the top plate 131 can all be connected by welding.

[0060] According to an embodiment of the present invention, another aspect is provided: a power container, including: a base 20; the aforementioned hoisting device 10, disposed on the base 20, the base 20 having a folded edge 201, the folded edge 201 being spaced apart from the end of the fixing structure 1 that has an insertion hole 11 to form a limiting space 2; and a container body disposed on the base 20.

[0061] Specifically, in one embodiment, such as Figures 3 to 8 As shown, the base 20 includes a longitudinal beam 202, and the fixing structure 1 is disposed within the longitudinal beam 202. Further, the longitudinal beam 202 includes an upper plate 2021, a lower plate 2022, and a connecting plate 2023. The upper plate 2021 and the lower plate 2022 are arranged at intervals relative to each other, and the connecting plate 2023 is connected between the upper plate 2021 and the lower plate 2022. The upper plate 2021, the lower plate 2022, and the connecting plate 2023 enclose an installation space. The fixing structure 1 is disposed within the installation space. The top plate 131 is connected to the upper plate 2021, and the bottom plate 132 is connected to the lower plate 2022. The edge of the lower plate 2022 is folded towards the upper plate 2021 to form a folded edge 201, which is arranged at intervals relative to one end face of the cylinder 14.

[0062] Furthermore, in one embodiment, the top plate 131 and the upper plate 2021 are welded together, and the bottom plate 132 and the lower plate 2022 are welded together.

[0063] It is worth noting that in the locked position, the lifting section 312 of the boom 31 is located outside the longitudinal beam 202, so as to be used in conjunction with the sling for lifting.

[0064] In one embodiment, such as Figure 3 As shown, several hoisting devices 10 are spaced apart on the base 20. Furthermore, two longitudinal beams 202 are spaced apart along the width direction, and several hoisting devices 10 are spaced apart on each longitudinal beam 202. Even further, the hoisting devices 10 on the two longitudinal beams 202 are arranged one-to-one in the width direction.

[0065] According to an embodiment of the present invention, in another aspect, a power supply vehicle is also provided, comprising: a vehicle body; and the aforementioned power supply container disposed on the vehicle body.
