Description

Technical Field

[0001] This utility model relates to the field of power maintenance equipment technology, specifically to hoisting equipment. Background Technology

[0002] In photovoltaic power generation projects, the installation, removal, and maintenance of photovoltaic inverters is a crucial step. Due to site constraints, when replacing electrical equipment near substation walls or in indoor high-voltage rooms, the limited space makes it impossible for cranes to reach the equipment, increasing the difficulty of on-site operations. In such cases, manual pushing, pulling, and lifting methods are used to move the equipment to the designated location.

[0003] In existing technologies, a hoisting device with clamps is typically used to lift, separate, and unload the photovoltaic inverter from the precast pile. During the hoisting operation, the clamps on the hoisting device are first connected to the precast pile, and then the hooks on the hoisting device are used to lift the photovoltaic inverter and remove it from the precast pile. However, in this type of hoisting device, the clamps are fixedly set on the column of the hoisting device, which makes it difficult to meet the requirements for fixing and connecting precast piles of different sizes. Utility Model Content

[0009] In one alternative embodiment, the clamp further includes an anti-slip pad disposed on the side of the clamp that contacts the precast pile.

[0010] Beneficial effects: The anti-slip pad on the side of the clamp that contacts the precast pile can increase the simple friction between the clamp and the precast pile, avoid slippage between the clamp and the precast pile when hoisting the photovoltaic inverter, and improve the stability of the hoisting equipment.

[0011] In one alternative implementation, the clamp and the lifting assembly are located on the same side of the column.

[0012] Beneficial effects: This utility model places the clamp and the hoisting component on the same side of the column, which facilitates the hoisting and removal of the photovoltaic inverter from the top of the precast pile.

The first beam is connected to the column, the second beam is movably connected to the first beam, and the hook is disposed at the bottom of the second beam. The lifting assembly is detachably installed on the hook.

[0014] Beneficial effects: This utility model movably connects the second beam to the first beam, allowing the photovoltaic inverter on the hoisting component on the hook to be hoisted and transferred by moving the second beam, reducing the need for workers to move the photovoltaic inverter.

[0015] In one alternative embodiment, a guide rail is provided on the first beam, and a roller is provided on the second beam, with the roller movably mounted on the guide rail.

[0016] In one alternative embodiment, the crossbeam further includes a support beam disposed at the bottom of the first beam and connected to the column.

[0036] In this embodiment, as Figure 1 As shown, the column 1 has several first mounting holes 11 along the vertical direction, and several clamps 4 are detachably installed in the first mounting holes 11. In this embodiment, the number of clamps 4 is not specifically limited. For example, in this embodiment, two clamps 4 are provided, and the two clamps 4 are detachably installed on the column 1. The clamps 4 are respectively connected to the precast pile 6 near the top and bottom. In some other embodiments, the number of clamps 4 can be adjusted according to the height of the precast pile 6.

[0037] In this embodiment, as Figure 1 As shown, the hoisting assembly 3 is detachably installed on the end of the crossbeam 2 away from the column 1. In this embodiment, the hoisting assembly 3 is not specifically limited. For example, in this embodiment, the hoisting assembly 3 can be a manual hoist.

In other embodiments, an electric hoist can also be used to reduce manual operation by operators.

[0038] This utility model has several first mounting holes 11 provided on the column 1 along the vertical direction. When the photovoltaic inverter 5 is hoisted and maintained on the precast piles 6 at different heights, the hoisting equipment can be connected to the precast piles 6 by installing the corresponding size clamp 4 in the corresponding first mounting holes 11. This improves the applicability of the hoisting equipment and has the advantages of simple structure and convenient operation.

[0039] In one embodiment, such as Figure 2 As shown, the clamp 4 includes a locking part 41, a first connecting part 42, and a second connecting part 43.

In this embodiment, the clamp 4 can be made of flat steel. In other embodiments, the clamp 4 can also be made of high-strength steel plate. The arc-shaped mounting part on the locking part 41 can be set according to the diameter of different precast piles 6. When installing on precast piles 6 of different diameters, the clamp 4 of the corresponding size can be selected.

[0042] In this embodiment, bolts are installed in the first mounting hole 11 and the second mounting hole 421, and corresponding bolts are installed in the third mounting holes 431 on the two second mounting parts. When installing the clamp 4, a suitable clamp 4 is selected, and the two locking parts 41 are first clamped on the outer wall of the precast pile 6. Then, the bolts are installed on the first mounting part and the second mounting part, so that the clamp 4 can be firmly connected to the precast pile 6. In this embodiment, there is no specific limitation on the bolts. For example, high-strength bolts can be used to ensure the stability of the connection between the clamp 4 and the precast pile 6.

[0043] This utility model connects the first connecting part 42 on the clamp 4 to the first mounting holes 11 at different positions on the column 1, so that the clamp 4 can be connected to the precast piles 6 at different heights. This allows the hoisting equipment to lift and remove the photovoltaic inverter 5 from the precast piles 6 at different heights for maintenance, thus improving the applicability of the hoisting equipment.

[0044] In one embodiment, such as Figure 2 As shown, the clamp 4 also includes an anti-slip pad 44, which is disposed on the side of the clamp 41 that contacts the precast pile 6.

The bottom of the end of the second beam 22 away from the column 1 is provided with a hook 23, and the hoisting assembly 3 can be detachably installed on the hook 23.

[0052] This utility model movably connects the second beam 22 to the first beam 21. By moving the second beam 22, the photovoltaic inverter 5 on the hoisting assembly 3 on the hook 23 can be hoisted and transferred, reducing the need for workers to move the photovoltaic inverter 5.

[0053] In one embodiment, such as Figure 1 As shown, the first beam 21 is provided with a guide rail 211, and the second beam 22 is provided with a roller 221, which is movably mounted on the guide rail 211.

[0054] Specifically, in this embodiment, the first beam 21 is provided with a horizontally arranged guide rail 211, and the bottom of the second beam 22 is provided with a roller 221. The roller 221 is movably installed on the guide rail 211.

[0055] In one embodiment, such as Figure 1 As shown, the crossbeam 2 also includes a support beam 24, which is located at the bottom of the first beam 21 and connected to the column 1.

[0056] Specifically, in this embodiment, the support beam 24 is inclinedly disposed between the first beam 21 and the column 1, with one end of the support beam 24 connected to the bottom of the first beam 21 and the other end connected to the side wall of the column 1.

[0057] The support beam 24 of this utility model forms a triangular structure with the first beam 21 and the column 1, which improves the stability of the crossbeam 2.

[0058] In one embodiment, such as Figure 1 As shown, the hoisting assembly 3 includes a drive assembly 31, a cable 32, and a hook 33. The drive assembly 31 is detachably mounted on the hook 23, the cable 32 is movably mounted on the drive assembly 31, and the hook 33 is connected to the cable 32.

[0060] In one embodiment, such as Figure 1 As shown, the hoisting equipment also includes a base 7, which is suitable for being set on the ground, and the column 1 is set on the base 7.

[0061] Specifically, in this embodiment, the base 7 has a rectangular plate structure and is located at the bottom of the column 1. The base 7 can increase the contact area between the bottom of the column 1 and the ground.

[0062] The present invention provides a base 7 at the bottom of the column 1, which can increase the overall stability of the hoisting equipment.

[0063] In one embodiment, such as Figure 1 As shown, the base 7 has a reinforcing rib 71 at the top, and the reinforcing rib 71 is connected to the bottom of the column 1.

[0064] Specifically, in this embodiment, the top of the base 7 is provided with a number of reinforcing ribs 71. The reinforcing ribs 71 are circumferentially arranged at equal intervals at the bottom of the column 1.

[0065] The present invention provides reinforcing ribs 71 on the base 7 to improve the stability of the connection between the column 1 and the base 7.

[0066] The process of using the hoisting equipment in this embodiment is as follows: In the preparation stage, two people need to work together to firmly attach the column 1 to the precast pile 6 where the photovoltaic inverter 5 is installed. First, adjust the base 7 below the column 1 to ensure that the contact surface is not collapsed. Then, select a suitable clamp 4 according to the size of the precast pile 6 and fix the clamp 4 firmly to the precast pile 6 and the column 1 with bolts. Next, connect the hoisting assembly 3 to the hook 23. Adjust the position of the hoisting assembly 3 according to the height of the inverter, and connect the hook 23 hole of the photovoltaic inverter 5 to the hook 33 on the hoisting assembly 3. Finally, one of the maintenance personnel observes whether the above operation steps are correct. After checking that they are correct, the other maintenance personnel drives the hoisting assembly 3 to slowly raise the photovoltaic inverter 5 until it is detached from the inverter slot at the top of the precast pile 6. The other observer manually adjusts the lowering position of the photovoltaic inverter 5 to prevent the inverter from shaking during the descent. The operation is completed when the maintenance personnel operate the hoisting assembly 3 to slowly lower the photovoltaic inverter 5 to the ground.

[0067] The hoisting equipment in this embodiment has a simple structure and is easy to move and operate. For work sites with narrow spaces where cranes cannot reach, maintenance personnel can move the hoisting equipment to the construction site, connect the clamp 4 to the precast pile 6 firmly, and then hoist the photovoltaic inverter 5. This greatly reduces the labor intensity of maintenance personnel in replacing the photovoltaic inverter 5 by manually pushing, pulling, and lifting.
