By adopting the technical scheme, the invention has the following advantages:
the invention provides a wheel derailment detection device, which is characterized in that a detection mechanism is arranged on a wheel set, and a proximity switch of the detection mechanism can send a switching signal to a control system at the first time to cut off power under the condition of derailment, so that the motion state can not be continuously kept under the condition of derailment, and the larger damage condition is prevented.
Drawings
Other features, objects and advantages of the present invention will become more apparent upon reading of the following detailed description of non-limiting embodiments thereof, with reference to the accompanying drawings.
Fig. 1 is a perspective view of a wheel derailment detection apparatus according to the present invention.
Detailed Description
The technical solutions of the present invention are described in detail below with reference to the accompanying drawings, and the detailed features and advantages of the present invention are described in detail in the detailed description, which is sufficient for anyone skilled in the art to understand the technical contents of the present invention and implement the present invention, and the related objects and advantages of the present invention can be easily understood by those skilled in the art from the description, the claims and the accompanying drawings disclosed in the present specification.
Fig. 1 is a perspective view showing a wheel derailment detection apparatus, and in one embodiment, as shown in fig. 1, the present invention provides a wheel derailment detection apparatus for a crane or a train, which includes rails 4 installed on the ground, the rails 4 being rigid members.
In one embodiment, the rails 4 are provided with crane carriages and in another embodiment, the rails 4 are provided with trolleys.
The wheel detection derailing device also comprises a wheel set arranged at the bottom of the traveling crane cart and a detection mechanism which is arranged on the end beams 1 at the two sides of the traveling crane cart and is close to the wheel set. In one embodiment, the wheel set comprises 4 wheels 2,4 wheels 2 which are positioned at the bottom of the end beams on the two sides of the crane cart and run on the rails 4.
In one embodiment, the detection mechanism comprises 4 proximity switches 3, each wheel 2 is provided with a proximity switch 3, the proximity switches 3 are connected with the wheels 2 in a one-to-one correspondence manner, four proximity switches are respectively 3 (1), 3 (2), 3 (3) and 3 (4) on the edges of the wheels 2, and the proximity switches 3 are used for detecting the distance between the wheels 2 and the rails 4.
In one embodiment, the proximity switch 3 detects the triggered state of the rail 4, and the switch signal is normally open or normally closed according to the control system requirement, and when the signal changes, the derailment condition occurs.
In one embodiment, whether the wheel is derailed or not is judged, and the position of the proximity switch 3 is determined and is in a normal trigger state under the condition of normal driving.
In addition, because the wheels 2 and the rails 4 are rigid parts, the distance between the track surface and the proximity switch 3 is determined, the proximity switch adopts a magnetic induction type switch or a photoelectric type switch, the wheels 2 generate derailment signals by adopting magnetic induction or photoelectric induction, and the proximity switch 3 is respectively connected with a control system and an electric control system of the traveling crane.
