Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wind generating set equipment, especially to a collecting ring maintenance platform. BACKGROUND

[0002] The wind generating set is a system for converting the kinetic energy of wind into electric energy, which needs to be adapted to the yaw of the main machine through the collecting ring, and the existing collecting ring is generally installed in the tower drum through a bent plate support structure, a plurality of detachable sub-panels (the sub-panels are connected with the bent plate support structure through screws) are arranged on the bent plate support structure, and a wire laying bridge is arranged at the bottom for laying cables.

[0003] 1. When the power cable and the power cable at the bottom of the bent plate support structure are laid and maintained, a certain sub-panel in the bent plate support structure needs to be disassembled in advance to enter the wire laying bridge, and each time the sub-panel is opened, the corresponding screws need to be unscrewed, so the work efficiency is low.

[0004] 2. The strength of the bent plate support structure is not high, and there is a certain risk when the maintenance personnel stand on the bent plate support structure to maintain the collecting ring.

[0005] 3. The bent plate support structure needs to be additionally holed for the power cable and the power cable to pass through, and if the hole is too small, the friction between the power cable and the power cable will be increased, which will affect the service life of the power cable and the power cable.

[0006] 4. The bent plate support structure needs to be additionally holed for heat dissipation, so as to facilitate the heat dissipation and ventilation of the tower drum. SUMMARY

[0007] The utility model aims at overcoming the defects of the prior art and providing a collecting ring maintenance platform.

[0008] To achieve the above-mentioned purpose, the utility model provides a technical scheme:

[0009] A collecting ring maintenance platform, comprising a mounting bracket, a support platform and a wire laying bridge.

[0010] The support platform is installed in the tower drum.

[0011] The collecting ring is connected with the support platform through the mounting bracket and is lifted by the mounting bracket.

[0012] The wire laying bridge is installed at the bottom of the support platform.

[0013] The mounting bracket and the support platform cooperate to form a channel through which people and cables can pass, and the entrance of the channel is arranged in the mounting bracket, the middle part of the channel passes through the support platform, and finally reaches the wire laying bridge.

[0014] In the technical solution, when the power cable and the power cable need to be laid and maintained, the maintainer can quickly enter the wire laying bridge inside the support platform from above the support platform through the formed channel, without the need to disassemble a certain sub-panel in the bending plate support structure in advance to enter the wire laying bridge, and the work efficiency is greatly improved.

[0015] Moreover, in the prior art, the corresponding screw needs to be unscrewed every time the sub-panel is opened, and the number of times of opening the sub-panel is too many, the screw is prone to slipping, and the sub-panel is not fixed firmly. The technical solution can avoid this situation.

[0016] In addition, in the technical solution, the power cable and the power cable connected with the current collector ring can enter the wire laying bridge inside the support platform through the formed channel, and the support platform does not need to be additionally holed for the power cable and the power cable to pass through. Since the channel can also be passed through by a person (a maintainer), the size is relatively large, so that the power cable and the power cable can be easily passed through, and the friction between the power cable and the power cable and the support platform will not be increased when the power cable and the power cable are twisted. In addition, the large size of the channel is also convenient for heat dissipation and ventilation inside the tower drum, and there is no need to additionally open a heat dissipation hole on the support platform.

[0017] Further, the support platform comprises a platform panel and a platform support frame.

[0018] The platform panel is installed in the tower drum through the platform support frame, and the platform panel and the platform support frame are both provided with a passageway hole.

[0019] The technical solution improves the strength of the whole support platform by installing the platform support frame at the bottom of the platform panel.

[0020] Further, the mounting bracket comprises a bracket body mounted on the support platform, and the entrance of the channel is arranged on the side surface of the bracket body. When the maintainer needs to lay the cable, the maintainer can enter the channel through the entrance and finally reach the wire laying bridge.

[0021] Further, the mounting bracket is provided with a reinforcing rib, and the two ends of the reinforcing rib are connected with the mounting bracket and the support platform respectively, for strengthening the strength of the mounting bracket.

[0022] Further, the outer side of the bracket body is provided with a guardrail, and the side surface of the bracket body is mounted with a channel door for closing the entrance of the channel.

[0023] In the technical solution, when the maintainer maintains the current collector ring, the channel door is in a closed state, and the channel door and the guardrail cooperate to prevent the maintainer from falling into the channel when maintaining the current collector ring.

[0024] Further, the bottom of the guardrail and the bottom of the passage door are provided with a kick plate to avoid the situation that the maintenance personnel steps on nothing when maintaining the current collector.

[0025] Further, the wire laying bridge is provided with a power cable twisting protection module opposite the passage hole of the platform panel and the passage hole of the platform support frame.

[0026] Further, the power cable twisting protection module comprises a mounting frame and a rubber protection sleeve mounted on the wire laying bridge through the mounting frame.

[0027] In the technical solution, the power cable passes through the rubber protection sleeve, preventing the power cable from being in rigid contact with the wire laying bridge when the power cable is twisted, avoiding generating a large friction force and affecting the service life of the power cable.

[0028] Further, the platform support frame is provided with a cable bracket, and the cable bracket is provided with a semicircular supporting part for supporting the power cable.

[0029] Further, the platform support frame is in the shape of a long ladder and is horizontally arranged in the tower drum to support the platform panel.

[0030] Compared with the prior art, the technical solution has the following principles and advantages:

[0031] The installation support and the supporting platform cooperate to form a passage through which people and cables can pass, and the passage is formed by the installation support at the entrance, the supporting platform in the middle, and the wire laying bridge at the end.

[0032] Moreover, in the prior art, the screws need to be unscrewed every time the sub-panel is opened, and the screws are likely to slip, the sub-panel is not fixed firmly, and the technical solution can avoid such a situation.

[0033] Furthermore, in this technical solution, both the power supply cable and the power cable connected to the slip ring can enter the cable tray at the bottom of the support platform through the formed channel, eliminating the need for additional openings in the support platform for these cables to pass through. Since the channel is also large enough for personnel (maintenance staff) to pass through, the power supply and power cables can pass through easily without increasing friction with the support platform when twisted. In addition, the large channel size facilitates heat dissipation and ventilation inside the tower, eliminating the need for additional ventilation holes on the support platform.
