Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment components, in particular to a wind power tower cylinder section welding auxiliary device. Background Art

[0002] The wind turbine generator set includes a wind rotor and a generator. The wind rotor contains blades, a hub, reinforcements, etc. It has the functions of generating electricity by the blades rotating under wind force and rotating the generator head. The wind power source consists of a wind turbine generator set, a tower supporting the generator set, a battery charging controller, an inverter, an unloader, a grid-connected controller, a battery pack, etc. The wind turbine generator is mainly composed of a wind turbine main engine, blades, and a tower. When welding the tower, a positioning plate is required to position the cylinder section. The positioning plate usually needs to be welded between two cylinder sections to facilitate subsequent welding. When welding the positioning plate, in order to facilitate welding, an auxiliary workpiece is required to assist it.

[0003] In the prior art, a Chinese patent document with patent number CN211361205U proposes an auxiliary device for the circumferential seam welding of a wind power tower cylinder, comprising a base, the base consisting of two parts, a fixed block is fixed at the end of one of the bases, and a placement groove is symmetrically opened inside one of the bases, a connecting column is arranged inside the placement groove, a handle is fixed at one end of the connecting column, and the other end of the connecting column penetrates the outside of the fixed block; through the designed movable block and movable groove, the connecting column is limited and movable inside the placement groove, and the handle is designed to facilitate the rotation of the connecting column, and through the designed connecting column, placement groove, connection groove, and connection hole, the two parts of the base are stretched, so that the parts fixed on the surface of the base can be stretched or shortened by the stretchability of the base, so that towers of different sizes are more closely fitted with the auxiliary device, but there are still problems in the actual use process. The contact positions of the existing two adjacent power tower barrel sections cannot be effectively clamped and aligned, resulting in the phenomenon of false welding and desoldering during the welding of the barrel sections, thus resulting in unstable welding, resulting in direct deviation of the power tower barrel section, thereby affecting the installation speed of the power tower. Therefore, the utility model proposes a wind power tower cylinder segment welding auxiliary device to meet the needs of improving the neatness between adjacent cylinder segments and thus improving the welding effect. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a wind power tower cylinder segment welding auxiliary device to solve the problem that the neatness between adjacent cylinder segments affects the welding effect.

[0005] Based on the above purpose, the utility model provides a wind power tower section welding auxiliary device, including an extension rod, which is in a hollow state, and is fixedly connected to a plurality of first fixed seats, one end of the extension rod is slidably sleeved with a sleeve ring, and the sleeve ring is fixedly connected with an adapter assembly, and the first fixed seat is rotatably connected with a plurality of support arms, and the support arms are rotatably connected with connecting arms, and one end of the connecting arm is fixedly connected with a grinding assembly; the adapter assembly is used to adjust the position of the connecting arm to cope with power tower sections of different sizes; the grinding assembly is used to clean and grind the inner wall of the power tower section.

[0006] Preferably, the adapter assembly includes a limit plate fixedly connected to one end of the extension rod, one end of the limit plate is fixedly connected to a return spring, one end of the return spring is fixedly connected to the sleeve ring, a group of second fixed seats are fixedly connected to the sleeve ring, the second fixed seat is rotatably connected to an extension arm, and one end of the extension arm is rotatably connected to the support arm.

[0007] Preferably, the grinding assembly includes multiple groups of cleaning arc plates fixedly connected to one end of the connecting arm, one end of the cleaning arc plate is fixedly connected to a contact slope, the contact slope is a semicircular structure, one side of the top of the cleaning arc plate is fixedly connected to a grinding groove, the top of the grinding groove is fixedly connected to multiple groups of grinding plates, and the grinding plates are curved arc structures.

[0008] Preferably, the other end of the connecting arm is rotatably connected to a vibration wheel, and a plurality of vibration grooves are provided on the surface of the vibration wheel.

[0009] Preferably, the cleaning arc plate is an arc-shaped structure deflected to one side.

[0010] Preferably, the height of the grinding plate is the same as the height of the contact slope.

[0011] Preferably, a plurality of flow grooves are provided on the contact slope, and the flow grooves are semicircular structures.

[0012] Beneficial effects of the utility model:

[0013] 1. When the wind power tower cylinder segment welding auxiliary device is used, the connecting arm is subjected to different extrusion strengths on the inner wall of the cylinder segment, thereby driving the connecting arm to deflect. The deflection of the connecting arm simultaneously drives the support arm to deflect, thereby causing the sleeve ring to move on the axis of the extension rod. The elastic force of the reset spring keeps the support arm in a relatively stable range, thereby achieving close contact with the inner wall of the cylinder segment, improving the stability during welding, and improving the welding effect.

[0014] 2. After the cleaning arc plate contacts the inner wall of the tower, when the extension rod moves forward, the cleaning arc plate can be an arc-shaped structure deflected to one side, so that the cleaning arc plate can move synchronously with the extension rod and rotate around the axis of the extension rod. At the same time, through the contact slope and multiple groups of flow grooves, the impurities on the inner wall of the tower are removed by the cleaning arc plate, and the impurities can flow out along the guide of the flow groove. At the same time, the grinding plate on the grinding groove contacts the cleaned inner wall of the tower, so that the cleaned position on the inner wall of the tower can be polished, thereby improving the subsequent welding effect and further improving the welding efficiency.

[0015] 3. When the inner wall of the tower is in contact with the vibration wheel, multiple groups of vibration grooves are opened on the surface of the vibration wheel. Through the height difference between the vibration grooves and the vibration wheel, the vibration wheel can vibrate the inner wall of the tower during movement, thereby improving the cleaning effect of the inner wall of the tower and further improving the efficiency of subsequent welding.
