Embodiment
Below in conjunction with the accompanying drawings and embodiment is carried out to Wind turbines tower detection device of the present invention and method
Describe in detail.
The present invention is based on tower weld seam detection execute-in-place, simplifies Wind turbines tower weld seam detection program and step, keeps away
Exempt from that tower surface baking vanish is polished and repaired, reduce weld seam detection workload.
Current wind power plant tower weld seam detection mainly by supersonic detector 2, is first carried out to commissure top layer baking vanish
Polishing reuses supersonic detector 2 and detected.This method can reach the purpose of flaw detection, but testing experiment is front and rear to be divided
Do not need that top layer baking vanish is polished and repaired, operating personnel and instrument and equipment need to be sent to high-altitude by hanging basket or support
Commissure, it is high, cumbersome and the problems such as potential safety hazard be present to there is cost.And the super of gain is adjusted according to tower material sample block
Sonic analyzer 2 can ignore influence of the tower top layer baking vanish to weld seam detection.
Based on above-mentioned principle, Wind turbines tower detection device of the present invention, examine wind power plant tower weld seam
It is safe and reliable to survey field test, economically feasible.As shown in Figure 1 to 4, the present invention includes a series of stretch cord threaded sleeve components
5th, the mechanical trolley 1 of a safe fall-proof lifting rope, loading supersonic detector 2, wherein the stretch cord threaded sleeve group
External thread sleeve 6 that internally threaded sleeve 7 that part 5 is set by a high intensity stretch cord, stretch cord one end, the other end are set and outer
Three universal wheels 8 that the surface of threaded sleeve 6 is fixed are formed, and four rolling 3 is provided between mechanical trolley 1 and tower, is set respectively
It is placed in four angles of mechanical trolley 1；The safe fall-proof lifting rope is high intensity pull rope, carries the machinery of supersonic detector 2
Dolly 1 is made up of mechanical trolley 1 and the two parts of supersonic detector 2, and wherein mechanical trolley 1 only carries as supersonic detector 2
Body, without power set, supersonic detector 2 is powered with electric wire by cabin interior power through cabin hoisting port along tower drum outer wall.Institute
State stretch cord threaded sleeve component 5 be divided into two groups respectively from mechanical trolley about 1 two fixing holes 4 pass through and around cylindrical tower
Cylinder one encloses, and is joined end to end by internal and external threads, and described safe fall-proof lifting rope one end is arranged on the fixed mount of supersonic detector 2, uses
Born in protecting supersonic detector 2 to prevent, the other end is fixed in cabin at safety rope suspension by cabin hoisting port.Thus
It can be seen that when climbing wall mechanical trolley 1 using stretch cord at the scene, two groups of stretch cords are selected according to tower bottom and top perimeter first
The quantity that every group of threaded sleeve component 5, wherein after two stretch cords are each passed through the fixation pipe above and below mechanical trolley 1
Every group of component joins end to end, it should be noted that stretch cord and pipe contact position need to do smooth treatment, go out both when avoiding using
Existing relative motion causes screw thread to trip.Then by the electric crane hoist cable in cabin, safe fall-proof rope and power supply power supply electric wire warp
Cabin afterbody hoisting port is delivered to tower bottom and is fixed on mechanical trolley 1, and the effect of safe fall-proof rope is to avoid mechanical trolley 1
Directly born when occurring unexpected, the effect of electric crane hoist cable is to provide traction power for mechanical trolley 1, and to avoid machinery small
The born offer dual fail-safe of car 1, power supply electric wire are to provide power supply for supersonic detector 2.During experiment, pass through electric crane
The forward travel distance of control machinery dolly 1, realize the continuous monitoring to tower weld seam.During package unit normal work, mechanical trolley 1
Tower drum outer wall is close under the fixation of stretch cord, is drawn along weld seam and moved up by electric crane, supersonic detector 2 enters
The uninterrupted flaw detection work of row.It is drawn to after being fulfiled assignment up to atop a tower, release electric crane lifting rope utilizes mechanical trolley 1 itself
Gravity is slowly drop down to tower bottom by roller 3.Such as there is situations such as elastic force fracture of rope, mechanical trolley 1 is by hoist cable and anti-fall
Safety rope protection is suspended in midair, then is put down its safety by hoist cable.
The present invention is only illustrated with above-described embodiment, and structure and size of each part and attaching method thereof are all to have
Changed, on the basis of technical solution of the present invention, all improvement carried out according to the principle of the invention to individual part and equivalent
Conversion, should not be excluded within protection scope of the present invention.
