The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.

A kind of propeller blade detecting tool, as shown in Figure 1 to Figure 3, including pedestal 1, the pedestal 1 are equipped with support and fill Set 2 and detection device 8；The support device 2 includes the left support frame 3 being set on the base and right support frame 20 and two The placement plate 15 being arranged between supporting rack；The placement plate 15 is equipped with several support elements 16, and each support element 16 slides setting In placement plate 15, placement plate both ends are connect by the guide rail being arranged on supporting rack with supporting rack；At the top of support frame as described above The rotating mechanism 5 rotated equipped with clamp system 4 and driving clamp system 4；The clamp system includes the holder of loop configuration 12 and holder on the clamp assembly that is arranged；The rotating mechanism includes annular outer cover 18, and the holder is arranged in shell 18 Interior, 18 inner wall of shell is equipped with the driving motor rotated for driving arm 12.

The detection device 8 includes the hoistable platform 7 being arranged on pedestal 1 and the detection group being arranged on hoistable platform 7 Part.The pedestal 1 is equipped with sliding rail 6, and the hoistable platform is arranged on sliding rail 6.It is additionally provided on the pedestal and is risen for pushing The executing agency 17 that drop platform slides on sliding rail, 17 one end of executing agency are fixed on the pedestal 1 of sliding rail one end, the other end It is connect with hoistable platform bottom, hoistable platform significantly moving on pedestal may be implemented by executing agency.The execution Mechanism can use electric pushrod.

The clamp assembly includes on the clamping plate 14 and rack inner wall being correspondingly arranged in holder for pushing clamping plate to press from both sides The push rod 13 of tight blade；13 one end of the push rod is fixed on holder 12, and the other end is connect with clamping plate 14.The clamping plate not with push away The side of bar connection is equipped with cushion pad；The cushion pad can use anti-slip rubber gasket, both clamping plate can be made more preferable in this way Clamping blade, and can prevent blade by press from both sides it is bad；Ensure the intact of blade, is conducive to the detection work of next step.

When needing to overhaul propeller blade, blade need to only be stretched into from the holder of pedestal one end, and from the pedestal other end Holder stretch out；Then can by clamp assembly clamp blade, so that blade is fixed in support device so that it is convenient to Detection device is to blade into detection.

The rotating mechanism 5 includes annular outer cover 18, and inside the shell, outer casing inner wall is equipped with for driving for the holder setting The driving motor of holder pivots.The driving motor drives holder to rotate inside the shell by transmission device, while can band Fixed blade rotation on dynamic holder；As blade rotates, detection device will start to be detected blade, as blade turns Dynamic one week, detection device will the propeller of whole detection herein it is whether cracked, be conducive to carry out blade quickly in this way Trial inspection；

At this point, worker can first control rotating mechanism, make the damage position detecting direction of blade；Again by placement plate It elevates to support blade by guide rail；By the support element in mobile placement plate, support element can be enable preferably to prop up Blade is propped up, prevents blade from occurring mobile or shaking；After supports support good blade, worker can control clamp system pine Open blade, make blade stablize be placed in placement plate, and then prevent blade when carrying out minute inspection due to holder pivots and Appearance is shaken or is shaken, and avoids influencing accuracy of detection；The placement plate can be fixed on by screw or fixed pin on guide rail, Being more advantageous in this way makes placement plate keep stablizing.

The detection components include the electronic slide unit 9 being arranged in hoistable platform upper surface, the sliding block 11 of the electronic slide unit 9 It is equipped with electric cylinder 10,10 one end of electric cylinder is fixed on sliding block 11, and the other end is equipped with the mounting portion for installing detecting instrument 19.The electric cylinder on sliding block can be moved by electronic slide unit, be conducive to detecting instrument and realized by a small margin on hoistable platform It is mobile, and electric cylinder drives due to the use of servo motor, it is possible to so that detecting instrument is steadily moved, detecting instrument can be controlled More close to blade surface, whether being conducive to detecting instrument, preferably to detect blade cracked, and carries out more refinement to blade The inspection of cause.

The vertical direction movement of detecting instrument not only may be implemented by hoistable platform 7, but also detecting instrument may be implemented the bottom of at Substantially moving on seat is conducive to detecting instrument and quickly finds blade maintenance position accurately；It can be driven again by electronic slide unit simultaneously Detecting instrument realizes the small size movement of horizontal direction, is conducive to the precision for improving instrument detection, makes instrument preferably to just detecting Position；It may then pass through electric cylinder to be again accurately pushed to detecting instrument near blade, realize more accurate detection.

In an alternative embodiment, pedestal can be designed to that hollow shell structure, pedestal are equipped with filler import 21 and fill out Material outlet 22；When equipment needs to fix preferably to be worked, so that it may to fill sandstone into pedestal by filler import Or soil, can allow pedestal more stabilization in this way is placed on ground, when detection device being made to detect blade, avoids pedestal Movement, which occurs, causes detection device detection inaccurate；When equipment needs mobile, so that it may to be exported chassis interior by filler Filler is discharged, and to mitigate the weight of equipment, equipment is facilitated to move.

The invention can not only quickly find the possible injury region of blade by detection device and rotating mechanism, And more careful inspection can be carried out to possible injury region by detection device, not only can be quickly found out damage Place, and detecting instrument can be made to carry out careful inspection close to injury region disease, while greatly accelerating inspection speed, again It may be implemented precisely to check, can quickly detected the injury region on blade；This detecting tool at work can be with By increasing the counterweight of pedestal, so that equipment is kept steadily of centre of gravity, prevent device inclined, avoid detection device detection inaccurate；It is this Equipment can also reduce the counterweight of pedestal when moving, and then mitigate weight of equipment to greatest extent to facilitate user's movement to set It is standby.

The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention Protection domain within.
