Description

Technical Field

[0001] The utility model relates to the technical field of electrical maintenance equipment, in particular to a maintenance vehicle device for an offshore module electrical station. Background Art

[0002] Traditional offshore electrical stations usually use sheet metal parts to build various chambers, and then place electrical equipment in the chambers, which have relatively wide spaces. However, the cost of construction at sea is high and the construction efficiency is low.

[0003] Nowadays, offshore electrical stations use modular shell structures. Workers first install electrical equipment on land using compact container shells, and then transport the entire station to the sea for installation after it is built. No construction is required, so the cost is low and the construction efficiency is high. However, due to the limitation of transportation capacity, the volume of the container body is smaller than that of the previous chamber shell. In the past, when it was necessary to repair or replace the electrical equipment in the chamber shell, lifting equipment could be used to lift the electrical equipment from the top of the chamber for repair or replacement. Since the space was larger in the past, it would not affect other equipment. However, a modular structure is now used with a smaller space. Lifting the electrical equipment from the top of the chamber will hinder other equipment and is not easy to implement. Therefore, some offshore electrical stations use conventional forklifts to extract electrical equipment. However, for electrical equipment with a long lateral distance, when the forklift is inserted into the electrical equipment and extracted, it is easy for the forklift to tilt up, and it is not easy to counterweight the forklift in the offshore electrical station, resulting in difficulty in operation and damage to the electrical equipment.

There are multiple roller assemblies 600, and they are evenly arranged at the bottom of the supporting frame body 200, thereby ensuring the balance of the center of gravity of the supporting frame body 200 and preventing the supporting frame body 200 from tipping over.

[0030] In some embodiments of the present invention, Figure 1 , 2 As shown, the displacement drive assembly 500 includes a second drive member 510, a driving wheel 520 and a direction adjustment member 530.

The direction adjustment member 530 is connected to the driving wheel 520 to change the moving direction of the frame 100.

[0031] The driving wheel 520 is rotatably arranged on the frame 100, and the direction adjustment member 530 may include a steering wheel rotatably arranged on the frame 100, the steering wheel is connected to the driving wheel 520, and the rotation of the steering wheel can drive the driving wheel 520 to rotate around a rotation axis perpendicular to the ground, thereby changing the moving direction of the frame 100, and the second driving member 510 may include a motor and a reduction gearbox, the motor is connected to the driving wheel 520 through the reduction gearbox, so that the motor drives the driving wheel 520 to move, and the electrical equipment can be dragged out.

[0032] In the utility model, the maintenance vehicle device is provided with not only a fork support assembly 400 but also a top support assembly 300 on the vehicle frame 100. In a narrow modular shell space, for electrical equipment with a large longitudinal distance and a small lateral distance, the fork support assembly 400 can be used to insert into the bottom or the bayonet position of the electrical equipment, and the staff disassembles the electrical equipment, and then the fork support assembly 400 is lifted to extract the electrical equipment, and the displacement drive assembly 500 drives the vehicle frame 100 to move so as to drag the electrical equipment out; for electrical equipment with a small longitudinal distance but a large lateral distance, the staff can extend the supporting frame 200 located on the side of the vehicle frame 100 into the bottom of the electrical equipment, and the staff disassembles the electrical equipment, and the top support assembly 300 is raised and lowered to lift the electrical equipment. Since the bottom of the supporting frame 200 is supported by a roller assembly 600, the maintenance vehicle device will not tilt up due to unbalanced center of gravity, and then the displacement drive assembly 500 drives the vehicle frame 100 to move so as to drag the electrical equipment out. The present design can load electrical equipment in a narrow space, and is convenient and reliable to use.

[0033] In some embodiments of the present invention, Figure 1 , 3 As shown, the support frame body 200 includes a first support frame 210 and a second support frame 220 which are spaced apart from each other. The first support frame 210 and the second support frame 220 are both in the shape of long strips. One end of the first support frame 210 and the second support frame 220 are both connected to the frame 100. There are at least two top support assemblies 300 which are respectively arranged on the first support frame 210 and the second support frame 220.

[0034] When the electrical equipment needs to be disassembled, the first support bracket 210 and the second support bracket 220 can extend into the bottom of the electrical equipment, and the gap between the first support bracket 210 and the second support bracket 220 can allow components such as the wiring terminals of the electrical equipment to pass through without causing obstruction and not easily causing damage to other equipment.

[0035] In some embodiments of the utility model, the first support bracket 210 and the second support bracket 220 are arranged parallel to each other. During the movement of the frame 100, the first support bracket 210 and the second support bracket 220 can move along the length direction of the first support bracket 210 and the second support bracket 220 to be inserted into or pulled out from the bottom of the electrical equipment.

The motor drives the nut to rotate, thereby causing the screw rod to rise and fall. The top end of the screw rod abuts against the electrical equipment through the top support member, and the top end of the screw rod and the top support member can rotate relative to each other. Therefore, during the rotation and lifting process of the screw rod, the electrical equipment will not be driven to rotate, but will only be driven to rise and fall, thereby preventing the electrical equipment from tipping over.

[0042] Specifically, the first lifting mechanism 420 includes a third driving member, a main gear, a slave gear and a zipper. The main gear and the slave gear are both rotatably arranged on the mounting frame 410. The zipper is wound around the main gear and the slave gear.

The third driving member can be a motor to control the rotation of the main gear, and the zipper drives the fork support member 430 to rise and fall.

[0043] In some embodiments of the present invention, in order to further expand the lifting height of the fork support member 430, as shown in FIG. Figure 1 As shown, the mounting frame 410 is movably disposed on the vehicle frame 100 , and the vehicle frame 100 is provided with a second lifting mechanism 700 , which is connected to the mounting frame 410 to drive the mounting frame 410 to be lifted up and down along the vehicle frame 100 .
