Detailed description of the invention

Below in conjunction with accompanying drawing, the pylon platform flip cover assembly of this utility model embodiment is described in detail.

As shown in Figure 1, this utility model embodiment discloses a kind of novel pylon platform flip cover assembly, including the platform panel 1 being arranged on pylon platform, the surrounding edge 2 being arranged on platform panel 1, on surrounding edge 2 arrange at least two pieces renovate plate and expansion link 8. Wherein, at least two pieces of renovate in plate first at least sides renovating plate 3 are provided with first parallel with surrounding edge 2 and renovate side plate 6, and first renovates plate 3 can be rotatably set in one end of surrounding edge 2, and adjacent renovating is articulated and connected between plate. One end of expansion link 8 is arranged on first and renovates on side plate 6, and its other end is arranged on surrounding edge 2 away from first one end renovating plate 3.

It is articulated and connected each other by arranging, at least two pieces of free-open-close can renovate plate, can avoid because using what monoblock renovated plate to open excessive height, cause platform distance flange connection surface too high and bring unhandy problem, carry out switching action by outfit expansion link 8 auxiliary simultaneously, the folding that less power carries out renovating plate can be used to handle, it is simple to operation.

Specifically, the around openings at pylon platform arranges platform panel 1, is vertically arranged contour surrounding edge 2 along the platform panel 1 around platform openings, and surrounding edge 2 lower end can be welded and fixed with platform panel 1. At least two pieces be hinged, the plate of renovating that can mutually fold is arranged on the upper end of surrounding edge 2. Can specifically set, from factors such as flange face height, the number renovating plate according to the size of platform openings, platform.

As mentioned earlier, as most side renovate version, first renovates plate 3 can be rotatably set in one end of surrounding edge 2. It is arranged on first parallel with surrounding edge 2 of the first at least side renovating plate 3 to renovate side plate 6 one aspect and renovate plate 3 to first to carry out side relative to the upset of surrounding edge 2 spacing, is used for expansion link 8 is installed on the other hand. Additionally, also can renovate, first, the linkwork that on side plate 6, setting is connected with surrounding edge 2. Such as, renovate first and side plate 6 arranges installing hole, renovate side plate 6 by bearing pin 5 by first and be removably secured to one end of surrounding edge 2.

Alternatively, expansion link 8 is renovated side plate 6 and is connected by fastening bolt 7 with first. In order to make first renovate plate 3 be fastened on surrounding edge 2 time, fastening bolt 7 does not interfere with surrounding edge 2, is provided with the groove 15 relative with fastening bolt 7 position on surrounding edge 2.

In the present embodiment, be provided with two and renovate plate, including hinged with surrounding edge 2 first renovate plate 3 and with first renovate plate 3 hinged second renovate plate 4, and first renovates plate 3 and second and renovates plate 4 parallel side-by-side and be located at surrounding edge upper surface.

Operator renovates plate 4 by manipulation second and carrys out this flip cover assembly of closure or openness. For convenience of folding, handle can be respectively provided with on the second upper and lower end face renovating plate 4. As depicted in figs. 1 and 2, the second upper surface centre position renovating plate 4 is provided with the first handle 9, the second centre position renovating plate 4 lower surface is provided with the second handle 14.

Further, being respectively arranged with second parallel with surrounding edge 2 renovate side plate 12 as in figure 2 it is shown, renovate plate 4 dual-side second, second renovates side plate 12 is supported on pylon platform. Preferably, second renovate side plate 12 and fit with it from the inner side at surrounding edge 2. That is, it is parallel with surrounding edge 2 and contour that second arranged renovates side plate 12, such second renovates plate 4 when closing, second bottom renovating side plate 12 can be fitted on pylon platform, and then can renovate the sidepiece of plate 4 from second and renovate the upset of plate 4 to second, folding play effect that is spacing and that support.

On this basis, second renovate on plate 4 away from first renovate plate 3 also can renovate flanging 16 to being arranged with second. Renovating plate 4 second and be fastened on platform panel 1, the second surrounding edge 2 renovating flanging 16 side corresponding thereto is fitted.

Hereinafter will be described in detail first renovate that plate 3 and second renovates between plate 4 hinged.

Renovate plate 3 and second first renovate power required when plate 4 folds for reducing, it is preferable that first renovates plate 3 renovates plate 4 and pass through Damping hinge 13 and be connected with second, in order to this flip cover assembly of folding as door and window.

Further, renovate plate 3 first and renovate with second that plate 4 is connected while being provided with first to renovate flanging 10, second renovates plate 4 is renovating that plate 3 is connected while being provided with reinforcement 11 with first, and the side of Damping hinge 13 is renovated flanging 10 with first and is connected, and opposite side is connected with reinforcement 11. Renovate plate 3 and the second junction renovating plate 4 arranges reinforcement 11 first, contribute to strengthening the durability of pylon platform flip cover assembly.

Additionally, for prevent first renovate plate 3 and second renovate plate 4 upset folding time extrude, can renovate first and between flanging 10 and reinforcement 11, be provided with suitable gap, gap as wide in 2mm��4mm. Certainly, in specifically used, if needing first to renovate plate 3 and second renovate the effect certain extruding occurring to reach stress between plate 4, the then problem that can be left out gap.

Hereinafter the operation of pylon platform flip cover assembly is described.

When operation/attendant enters pylon platform, needs to open pylon platform flip cover assembly from bottom, available have gentle hands pushes away second and renovates plate 4 (simultaneously gently drawing the second handle 14), make while first renovates and turn on plate 3, second renovates plate 4 can go to design attitude at the drive backspin of Damping hinge 13, renovates plate 3 with first and forms certain angle. When expansion link 8 is opened to design attitude, making first to renovate plate, now Damping hinge 13 also rotates to design attitude, and making second, to renovate plate 4 vertical with platform panel 1 plane with the 1st or renovate plate 3 at an angle and fold, and is in open mode, as shown in Figure 3. Now, operation/attendant can enter pylon platform.

After operation/attendant fulfils assignment on pylon platform, can renovate first plate 3 and second renovate plate 4 close be buckled on surrounding edge 2, draw second to renovate the first handle 9 on plate 4 with have gentle hands, make Damping hinge 13 and expansion link 8 action, it is achieved renovate the Guan Bi of plate.

Adopt the mode that preferred expansion link 8 supports and Damping hinge 13 is folding so that two pieces renovate plate can automatic open-close, both having solved a monoblock, to renovate plate excessive, the problem taking the confined space, also solves that to renovate plate overweight, the problem of free-hand folding difficulty.

This utility model embodiment additionally provides a kind of wind-power generating unit tower, is provided with above-mentioned pylon platform flip cover assembly on pylon platform.

The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change can be readily occurred in or replace, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with described scope of the claims.
