Embodiment Construction
[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0024] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

The invention provides a recovering device for an iron tower component, and belongs to the technical field of iron tower overhauling tools. The device comprises a support, and lever type clamps whichare symmetrically arranged on the support, wherein each clamp comprises a driving part which is connected to a power device, and a clamping part for clamping the iron tower component; the driving parts and the clamping parts are correspondingly positioned at two ends of the clamps, and the two clamps are correspondingly hinged with the support; and the two driving parts are correspondingly connected to the power devices through intermediate connectors. According to the device, the two driving parts are correspondingly driven to move away from the iron tower component through the power devices,and the deformed part of the iron tower component is clamped through the two clamping parts, and thus the deformed part of a power transmission iron tower component can be recovered to be flat and straight under the effect of the clamping force of the two clamping parts, and bolt holes of the recovered power transmission iron tower component and another iron tower component can be moved, and thusthe working efficiency of removing fault of a power transmission iron tower can be improved. The device is simple in structure, and low in manufacturing cost; and the workload of construction workersis decreased.
Description
technical field [0001] The invention belongs to the technical field of iron tower maintenance tools, and more specifically relates to a reset device for iron tower components. Background technique [0002] As the scale of the grid continues to expand, the number of transmission towers is also increasing. Due to the size error of the transmission tower during assembly. Since the transmission tower is affected by atmospheric corrosion and temperature changes during use, it must be overhauled after a certain time interval. Affected by atmospheric corrosion and temperature changes, the components of the transmission tower will be deformed such as bending and bulging, resulting in misalignment of the bolt connection holes between the two components, resulting in the inability of the connecting bolts to pass through the connection holes. In the prior art, the deformed components are disassembled from the transmission tower and re-drilled for positioning. This method is time-cons...
