Problems solved by technology
[0002] The rails of railcars installed and used in cities must be frequently inspected for damage during use. The existing flaw detection trolley detects through the contact of several detection heads in the middle of the frame with the rail, but the existing components of the flaw detection trolley They are all connected by hinges. Due to the small lifting height of several detection heads, they are easy to be scratched and damaged when they are idle during driving and do not need to be detected during driving, especially when encountering fork roads and complex road surfaces.

Embodiment Construction
[0010] figure 1 , 2 As shown: the detection beam 1 fixed on the flaw detection trolley 11 is distributed with several connecting arms 2, and the lower parts of the several connecting arms 2 are all movably connected to the crank 4 with the detection head 3 through the hinge shaft 5, and the detection beam 1 is equipped with a Adjust the adjustment shaft 6 arranged longitudinally on the probe head 3. The adjustment shaft 6 is equipped with several reel wheels 7 distributed in the same position as the probe head 3. The set reel wheels 7 pass through the wound traction rope 8 and the crank 4 Connection; the outer end of the adjustment shaft 6 is provided with an adjustment handle 9, and the adjustment shaft 6 is also equipped with a ratchet 10 for stopping.
[0011] The traction rope 8 involved in this technical solution can be configured with a nylon rope, and the ratchet 10 can be installed at the end of the adjustment frame 1 by setting the ratchet shaft head for movable inst...

The invention provides an adjustable detection assembly mounted and used on a rail flaw detection trolley. A plurality of connecting arms are distributed on a detection beam fixed and used on a flaw detection trolley; cranks with detection heads are movably connected under the plurality of connecting arms through hinge shafts; longitudinally arranged adjusting shafts used for adjusting the detection heads are mounted under the detection beam; a plurality of winding wheels whose positions are as same as the positions of the detection heads sleeve the adjusting shafts; the plurality of winding wheels sleeving the adjusting shafts are correspondingly connected with the cranks through wound traction ropes; adjusting handles are arranged at the external ends of the adjusting shafts; and ratchetwheels used for stopping are also mounted on the adjusting shafts. According to the adjustable detection assembly mounted and used on the rail flaw detection trolley, the plurality of detection headscan be manually adjusted to rise and fall to an appropriate height by using the adjusting handle; therefore, the plurality of detection heads can fall down while in use, the plurality of detection heads can fall to be in contact with a rail to perform detection while in use; and the detection heads can be lifted to the appropriate height in an idling state so as to avoid the scratch phenomenon ofthe flaw detection trolley.
Description
technical field [0001] The invention relates to a rail flaw detection trolley assembly, in particular to an adjustable detection assembly installed and used on a rail flaw detection trolley. Background technique [0002] The rails of railcars installed and used in cities must be frequently inspected for damage during use. The existing flaw detection trolley detects through the contact of several detection heads in the middle of the frame with the rail, but the existing components of the flaw detection trolley They are all connected by hinges. Due to the small lifting height of several detection heads, they are easy to be scratched and damaged when they are idle during driving and do not need to be detected during driving, especially when encountering fork roads and complex road surfaces. . Contents of the invention [0003] The invention provides an adjustable detection assembly installed and used on a rail flaw detection trolley, which allows several detection heads of t...
