DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] like Figure 1-3 As shown, a tool for drilling a hole in a nacelle cover of a wind turbine generator comprises:
[0026] Platform 1;
[0027] Two support columns 2, the two support columns 2 are respectively arranged on both sides of the platform 1;
[0028] The limit frame 3 is composed of two long strips. The cross section of the long strip used by the limit frame 3 is set to a "cross" structure, which can improve the stability of the positioning component 4. The two ends of the limit frame 3 are respectively connected and fixed to the support column 2. The limit frame is provided with a scale, and the hole distance can be accurately positioned by the scale;
[0029] A mounting frame 7, the mounting frame 7 is fixedly connected to the platform 1;
[0030] The positioning assembly 4 is connected to the limit frame 3 and the drilling position is accurately adjusted through the limit frame 3. The positioning assembly 4 includes a plurality of adjustment units, each of which includes four rotating plates 41 forming a rhombus. The four rotating plates 41 are respectively connected to two connecting shafts 42 and two positioning shafts 43. The two rotating plates 41 on the upper side are rotatably connected through the connecting shafts 42, and the two rotating plates 41 on the lower side are rotatably connected through the connecting shafts 42. The two positioning shafts 43 are located on the left and right sides of the four rotating plates 41 forming a rhombus. A drilling hole 44 that cooperates with the drill bit is opened in the positioning shaft 43. The positioning shaft 43 is connected to the adjustment assembly 5. The plurality of positioning shafts 43 are all slidably connected to the limit frame 3. The adjustment assembly 5 can meet the requirements of adjusting the positions of the plurality of positioning shafts 43 at the same time, thereby meeting the requirements of adjusting the plurality of drilling positions at the same time when drilling holes at equal distances. The reference position can be met by fixing the leftmost positioning shaft 43 to the limit frame 3.
[0031] The adjustment assembly 5 includes multiple adjustment plates 51, in which a waist-shaped groove 52 with a size matching the connecting shaft 42 is opened. The connecting shafts 42 on the upper and lower sides are inserted into the waist-shaped groove 52. A connecting groove 53 is opened in the middle of the adjustment plate 51. The connecting groove 53 cooperates with the limit frame 3 and is slidably connected. Through the connecting groove 53, the adjustment plate 51 can slide on the limit frame 3, so as to adapt to the adjustment of multiple positioning positions, and at the same time, the connection line of the two connecting shafts 42 of each adjustment unit is in a vertical state.
[0032] Multiple connecting shafts 42 at the bottom are commonly connected to a lifting plate 61, and a shaft sleeve 62 is respectively connected to both sides of the lifting plate 61. The two shaft sleeves 62 are respectively slidably connected to the support column 2, and the bottom of the lifting plate 61 is connected to multiple hydraulic cylinders 63. The number of hydraulic cylinders 63 is not less than four, and the multiple hydraulic cylinders 63 are fixedly connected to the mounting frame 7. In this way, the multiple connecting shafts 42 at the bottom can be moved upward through the operation of the multiple hydraulic cylinders 63, so that the positions of the multiple positioning shafts 43 can be adjusted by adjusting the adjustment component 5 and the positioning component 4, and can be conveniently adjusted according to the designed hole spacing.
[0033] When the utility model is in use, the platform 1 is raised to a suitable drilling position of the engine room cover by an external elevator, and the leftmost drill hole 44 can be used as a reference position, and then the distance between two adjacent drill holes 44 is adjusted to the hole spacing size according to the hole spacing in the design drawing. Then, the distances of subsequent adjacent drill holes 44 are the same as the hole spacing, so the drill holes 44 will coincide with the designed drilling positions. Therefore, the engine room cover can be drilled through multiple drill holes 44 manually or automatically, which is convenient to use.
[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
