Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary devices, and in particular relates to a welding auxiliary device for a ladder support plate outside a wind power tower door. Background Art

[0002] The wind turbine tower is a wind turbine component that supports the nacelle and wind rotor, and plays a major supporting role in wind turbines. Since the wind turbine tower is located at a high altitude, workers need to climb a ladder to reach the wind turbine tower door and then enter the wind turbine tower. The ladder consists of connecting plates on both sides of the wind turbine tower door and supporting plates welded between the connecting plates on both sides. In order to ensure the accuracy of welding, welding auxiliary devices are often used.

[0003] For example, the patent number is CN201720965459.4, and the patent name is a welding auxiliary device for the ladder support plate outside the door of a wind turbine tower, which includes two relatively arranged and partially overlapping L-shaped adjustment plates. The L-shaped adjustment plate includes a scale plate and a clamping plate vertically fixed on one side of the scale plate. The two L-shaped adjustment plates can be locked and fixed as one by the positioning bolts and positioning nuts to prevent the two L-shaped adjustment plates from sliding relative to each other.

[0004] However, in the process of using the above scheme, when adjusting the two L-shaped adjustment plates, it is necessary to tighten the positioning bolts to adjust the width of the L-shaped adjustment plates. Since the positioning bolts need to be tightened during adjustment and fixing, it is inconvenient to use during adjustment and fixing. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a welding auxiliary device for the ladder support plate outside the wind turbine tower door. Under the action of the first spring rebound, the fixed column is driven to reset, and the L-shaped baffle is also driven to reset. When the L-shaped baffle is reset, the surface will be stuck between two blocks and inside a positioning groove, which has the effect of fixing the first adjustment plate and the second adjustment plate, making it easy to adjust and fix for use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind power tower door external ladder support plate welding auxiliary device, comprising a first adjusting plate, a second adjusting plate and a fixed frame, the surfaces of the first adjusting plate and the second adjusting plate are respectively provided with scales, the surface of the first adjusting plate is provided with a second long hole, the surface of the second adjusting plate is provided with a first long hole, the interior of the first long hole is provided with a plurality of positioning grooves, the interior of the second long hole is fixedly connected with a plurality of blocks, the interior of the fixed frame is fixedly connected with a fixing cylinder, the interior of the fixing cylinder is fixedly connected with a first spring, one end of the first spring is fixedly connected with a fixing column, the end of the fixing column away from the first spring movably passes through the fixing frame, the end of the fixing column away from the first spring is fixedly connected with a pressing block, the surface of the fixing column is provided with a notch, the interior of the notch is fixedly connected with an L-shaped baffle, and the L-shaped baffle is located between the two blocks and inside a positioning groove.

[0007] Furthermore, the surfaces of the first adjustment plate and the second adjustment plate are both movably sleeved with a sliding sleeve, the interior of the sliding sleeve is provided with two circular holes, the interior of the circular hole is fixedly connected with a second spring, and the surface of the sliding sleeve is provided with a pointer.

[0008] Furthermore, a ball is fixedly connected to one end of the second spring, and a plurality of fixing grooves are respectively formed at the bottom ends of the first adjustment plate and the second adjustment plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The movement of the pressing block drives the movement of the fixed column, and the fixed column drives the movement of the L-shaped baffle, and at the same time squeezes the first spring. After the L-shaped baffle moves, it is no longer stuck between the blocks and moves out of the positioning groove. At this time, the first adjustment plate or the second adjustment plate can be dragged to move so that the distance between them is the same as the width of the support plates on both sides of the actual wind tower door, and then the pressing block is released. At this time, the first spring rebounds and drives the fixed column to reset, and at the same time drives the L-shaped baffle to reset. When the L-shaped baffle is reset, the surface will be stuck between the two blocks and inside a positioning groove, which has the effect of fixing the first adjustment plate and the second adjustment plate, making it easy to adjust and fix for use.

[0011] 2. When the sliding sleeve is moved, it can slide directly to drive the pointer to the center position between the first adjusting plate and the second adjusting plate. The second spring can be set to rebound and reset the ball. During the sliding process, the two balls will be respectively stuck in the fixed grooves opened at the bottom ends of the first adjusting plate and the second adjusting plate, which can prevent the sliding sleeve from moving at will and facilitate the adjustment of the position of the sliding sleeve.
