Description
Technical field
The utility model relates to a kind of wind-power tower welding earthing device, belongs to welding technology field.
Background technology
Wind-power tower is wind turbine generator critical support position, and the unit that current wind power generation is generally installed is 2.0MW, 2.5MW and 3.0MW.Wherein 2.0MW unit engineering is the most common, the parameter following (for bright positive Wind turbines) of its wind-power tower: high 82 meters, maximum gauge 4.2 meters, minimum diameter 3 meters, it is by the steel plate of 32 pieces of different-thickness, roll and be welded into shell ring, then by weld seam docking composition one section of conical shell, the middle flange bolt that relies on connects.This wind-power tower it be with each weld seam assembly welding to tank body together, quantity every suit tower cylinder of weld seam reaches more than 1000 meter (interior outside weld), and this does not wherein also comprise welding of contents and doorframe, does not also calculate the number of channels of every bar weld seam welding.The visible tank body product for this middle pressure of wind-power tower, low temperature, the workload of welding is very large.And in welding process, in order to ensure that flange surface is injury-free, require that the ground wire of welding can not contact at flange.But a lot of Ta Tong manufacturer at present, their earth connection is all nonstandard, and arbitrarily a welding iron plate clip, is clipped in flange surface, or more coarse way, and directly plug is inside flange hole.Add the workload of reprocessing, also damage the surface of flange.On market, some regular earth clips can not be suitable for the rolling welding of this cone of tower cylinder at all, clamp the annex of tower cylinder inside, but weld with the rolling of cylindrical shell, the earth cable generated heat is made to be suspended in the air, there is potential safety hazard, add and this also increases ground wire consumption, improve the cost of welding.。
Utility model content
The utility model is in order to more convenient and quicker, safer, more guarantees the quality, the welding job completing wind-power tower of more saving, and proposes a kind of wind-power tower welding earthing device of applicable wind-power tower welding.
For solving the problems of the technologies described above, technology of the present utility model by the following technical solutions:
A kind of wind-power tower welding earthing device, comprise support plate, bearing, cylinder, swinging arm and rolling bearing, described support plate is located on described bearing, described cylinder is installed on the front end of described swinging arm by described rolling bearing, the upper end of described support plate is located in the rear end of described swinging arm, and can rotate in the upper end of described support plate, and described support plate is provided with resilient mounting, described resilient mounting connects described swinging arm, and when making work, cylinder is adjacent to tower cylinder surface.
As preferably, described resilient mounting is bolt spring, and described bolt end is located on described support plate, and described spring terminal points to described swinging arm, thus the degree of tightness by controlling bolt carrys out the stroke of regulating spring.
As preferably, described support plate falls plate for stretching, and can regulate the height of cylinder significantly, thus the tower cylinder to arbitrary specification size, and the utility model can the realization of perfect ground connection to roll welding.
As preferably, described cylinder is tin copper rod, both can improve ground connection performance, also can not cause damage to the surface of tower cylinder simultaneously.
As preferably, described bearing is fixture type bearing, thus can the utility model be arranged on the base crossbeam of turning rolls by bolt, along with turning rolls moves together, pulling down after so just not needing to have welded one section of tower cylinder is installed on other tower cylinder again, eliminate the dismounting operation to ground wire, save the operating time.
The utility model utilizes the welding earthing device of rolling contact type, no longer needs earthing device to be pressed on flange, ensure that flange surface is injury-free; Adopt tin copper as contact, avoid the damage of welding earthing device to tower cylinder surface mother metal of rolling; The fixture type bearing of flexible dismounting, makes the mode of welding so safer, the thing of hurting sb.'s feelings that drops of unnecessary worry high temperature ground wire; Reduce the use of ground wire, do not need to arrange too many welding ground in workshop, save the spending of ground wire.
Compared with prior art, the beneficial effect that the utility model has is:
1, Welding Safety is reliable, easy to use.
2, weld job is wide, can be suitable for the welding of different model set tower drum.
3, save welding cost, the welding job of energy continuous print, welding efficiency, without the need to dismounting, is improved in midway.
4, make simply, cost cost is low.
Accompanying drawing explanation
Fig. 1 is the end view of the utility model preferred embodiment;
Fig. 2 is the vertical view of the utility model preferred embodiment.
In figure: 1-support plate; 2-bearing; 3-cylinder; 4-swinging arm; 5-rolling bearing; 6-bolt spring.
Embodiment
For the understanding the utility model making those skilled in the art more clear and intuitive, below in conjunction with accompanying drawing, the utility model is further described.
Be preferred embodiment of the present utility model as shown in Figure 1-2.
A kind of wind-power tower welding earthing device, comprise support plate 1, bearing 2, cylinder 3, swinging arm 4 and rolling bearing 5, support plate 1 is located on bearing 2, cylinder 3 is installed on the front end of swinging arm 4 by rolling bearing 5, the upper end of support plate 1 is located in the rear end of swinging arm 4, and can rotate in the upper end of support plate 1, and support plate 1 is provided with bolt spring 6, bolt spring 6 connects swinging arm 4, and when making work, cylinder is adjacent to tower cylinder surface.
The bolt end of bolt spring 6 is located on support plate 1, and spring terminal points to swinging arm 4, thus the degree of tightness by controlling bolt carrys out the stroke of regulating spring; Particularly, support plate 1 falls plate for stretching, thus can regulate the height of cylinder significantly, thus the tower cylinder to arbitrary specification size, the utility model perfect ground connection can realize rolling welding; Cylinder 3 is tin copper rod, both can improve ground connection performance, also can not cause damage to the surface of tower cylinder simultaneously; Bearing 2 is fixture type bearing, thus can the utility model be arranged on the base crossbeam of turning rolls by bolt, along with turning rolls moves together, pull down after so just not needing to have welded one section of tower cylinder and be installed on other tower cylinder again, eliminate the dismounting operation to ground wire, save the operating time.In addition, the earth connection of welding machine just can be built on bearing very easily, is twisted by bolt one.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
