Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the following specific embodiments.

As shown in fig. 1, 2 and 3, the utility model comprises a trolley body 1; it is foreseen that some bearing pieces are provided on the trolley body 1 for placing the rail parent metal flaw detection and rail weld flaw detection devices, such as a hanger, a storage space, a bearing plate, etc., and the above structures may be set according to actual requirements, which is not an utility model point of the present utility model, and the present utility model is not repeated. In addition, in order to facilitate pushing or lifting the trolley, a pushing handle 4 is arranged at the rear of the top of the trolley body 1, and a lifting handle 5 is arranged at the side of the trolley body 1.

The bottom of the trolley body 1 is provided with land wheels 2 for land running and rail wheels 3 for rail running; for stable running, the number of the rail wheels 3 is two, and the rail wheels are arranged front and back; the number of Liu Hanglun is four, and the Liu Hanglun is respectively arranged at two sides of the rail wheel 3. The road wheel 2 comprises a contracted state and an extended state; when the land wheel 2 is in a contracted state, the lower tread of the land wheel is higher than the lower tread of the rail wheel 3; when the land wheel 2 is in an extended state, the lower tread surface of the land wheel is lower than that of the rail wheel 3.

When the land wheel 2 is in an extended state, the lower tread surface of the land wheel is higher than the rail wheel 3, and the road wheel 2 can contact the ground for running. While running on the track, the land wheel 2 is in a contracted state, and the lower tread surface of the land wheel is higher than the track wheel 3, so that interference is avoided.

In order to achieve the two states, in the utility model, the land wheel 2 is fixed on the connecting plate 6, and the connecting plate 6 is connected with the trolley body 1 by a rotating shaft, so that the connecting plate 6 can turn around the rotating shaft in the up-down direction; also included are positioning means 7 for positioning the connection plate 6, said positioning means 7 being able to position the connection plate 6 in a contracted state or in an expanded state.

Specifically, the positioning device 7 comprises a plunger pin 71 arranged on the connecting plate 6, and the trolley body 1 is provided with at least two positioning holes 8; the plunger pin 71 moves in the axial direction thereof to be inserted into or removed from the positioning hole 8; when the pin plunger 71 is inserted into one of the positioning holes 8, the Liu Hanglun 2 is positioned to the contracted state; when the pin plunger 71 is inserted into the other positioning hole 8, the Liu Hanglun 2 is positioned to the extended state; a pre-tension spring 74 is also included for pressing the pin plunger 71 into the locating hole 8.

In order to enable the land wheel 2 to be locked in the two states, the two positioning holes 8 are arranged at 90 °, one of which is located at the side of the rotating shaft and one of which is located directly above the rotating shaft (the positioning device 7 and the land wheel 2 are respectively arranged at two sides of the rotating shaft). Thus, when the pin plug 71 is inserted into the positioning hole 8 above the rotation shaft, the Liu Hanglun 2 is in the extended state. When the pin plug 71 enters and exits the positioning hole 8 at the side of the rotating shaft, the Liu Hanglun 2 is in a contracted state and can be tracked.

To facilitate pulling of the plunger pin 71, the rear end of the pin plunger 71 is provided with a handle 73. In addition, for convenience of installation, a tubular mounting sleeve 72 is arranged on the connecting plate 6, and the pin plunger 71 is arranged in the mounting sleeve 72 and extends or retracts the mounting sleeve 72 by sliding back and forth along the mounting sleeve 72; the pre-tightening spring 73 is sleeved on the pin plunger 71.
