All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides an anti-derailment track conveying system based on finite element analysis, which is suitable for application scenes of conveying track materials between a mountain top and a mountain foot, can effectively prevent a transport locomotive from being separated from a track, and improves the safety of the transport locomotive in the advancing process.
Referring to fig. 1 to 3, in the present embodiment, an anti-derailing track transportation system based on finite element analysis includes a guideway 1, a transportation vehicle 2, and an anti-derailing mechanism 3.
The guide rail 1 is of an I-shaped structure, and a plurality of iron blocks 101 arranged at intervals are arranged on two sides of the upper end of the guide rail 1. The bottom of the transport locomotive 2 is provided with an axle 201 and a square sliding rod 202, wheels 203 are fixedly arranged on the axle 201, and the wheels 203 move along the guide rail 1.
The derailment prevention mechanism 3 comprises two limiting plates 301, two magnetic induction coils 302, two return springs 303 and an energy conversion assembly 4.
The two limit plates 301 are slidably mounted on the square slide bar 202 and are respectively arranged at two sides of the guide rail 1. Each limiting plate 301 is provided with one magnetic induction coil 302, and the magnetic induction coil 302 is attracted to the iron block 101 after being electrified, so that the corresponding limiting plate 301 slides towards the guide rail 1, and the transport locomotive 2 is further limited to be separated from the guide rail 1. The two return springs 303 and the two limiting plates 301 are arranged in a one-to-one correspondence manner; the return spring 303 is sleeved on the square sliding rod 202 and used for driving the corresponding limiting plate 301 to slide towards a direction away from the guide rail 1.
Further, the limiting plate 301 is provided with a U-shaped groove 3011 having an opening facing the guide rail 1, the limiting plate 301 is close to the guide rail 1 under the action of magnetic force, so that the upper portion of the guide rail 1 is inserted into the opening of the U-shaped groove 3011, and the limiting plate 301 is limited to be detached from the guide rail 1.
The energy conversion assembly 4 is used for converting the mechanical energy of the axle 201 into the electric energy required by the magnetic induction coil 302.
Further, the energy conversion assembly 4 includes a rotor 401, a stator 402, a control circuit board, and a storage battery.
In this embodiment, the rotor 401 is sleeved on the axle 201 and rotates with the axle 201; the stator 402 is sleeved outside the rotor 401 and fixed to the bottom of the transportation vehicle 2. In this embodiment, the stator 402 is a winding coil, and the rotor 401 is a magnet assembly. The structure is convenient for wiring and can effectively reduce the production difficulty.
Specifically, the magnet assembly includes an N-pole magnet and an S-pole magnet. The winding coil and the magnetic induction coil 302 are respectively electrically connected with the storage battery through the control circuit board.
It should be noted that the working principle of the derailment prevention track conveying system based on finite element analysis is as follows:
s10: when the transport locomotive 2 stops on the guide rail 1, the energy conversion assembly 4 does not supply power to the magnetic induction coil 302, and the magnetic induction coil 302 does not generate a magnetic field for attracting the iron block 101, so that under the driving action of the return spring 303, the two limit plates 301 slide towards the direction away from the guide rail 1, and the upper part of the guide rail 1 is separated from the U-shaped groove 3011, at the moment, a constructor can easily take down the transport locomotive 2 from the guide rail 1 for operations such as maintenance and the like;
s20: when the transport locomotive 2 travels on the guide rail 1, the axle 201 drives the rotor 401 to rotate, the stator 402 passively cuts magnetic induction lines generated by the rotor 401 to obtain induction currents, and the storage battery is powered through the control circuit board;
s30: after the storage battery is powered on, the control circuit board can supply power to the magnetic induction coil 302, the magnetic induction coil 302 generates an electromagnetic field after being powered on, and the electromagnetic field is mutually attracted with the iron block 101, so that the elastic action of the return spring 303 can be overcome, the two limiting plates 301 are driven to slide towards the direction close to the guide rail 1, the upper part of the guide rail 1 is inserted into the U-shaped groove 3011, and the transport locomotive 2 is limited to be separated from the guide rail 1.
It should be noted that, in some other embodiments, the storage battery may be omitted, and the induced current obtained by the energy conversion assembly 4 is directly supplied to the magnetic induction coil 302 after being converted by the control circuit board, which has the following advantages:
firstly, a storage battery is saved, and the material cost is saved;
even if the storage battery is saved, the functions of loosening the guide rail 1 when the vehicle stops and clamping the guide rail 1 when the vehicle advances can be kept:
only when the transport locomotive 2 travels, the energy conversion assembly 4 can obtain induced current, and then the limiting plate 301 is driven to slide towards the guide rail 1 for limiting;
when the transport vehicle 2 stops running, the energy conversion assembly 4 cannot obtain induced current, and the limiting plate 301 is far away from the guide rail 1 under the action of the return spring 303, so that a constructor can take the transport vehicle 2 off the guide rail 1 for maintenance.
It is understood that, as a core component of the derailment prevention mechanism 3, mechanical properties such as rigidity, hardness, brittleness, and fatigue strength of the stopper plate 301 are important. Once the limiting plate 301 is cracked during the traveling process due to careless material selection, the anti-derailment function is completely lost, and therefore, the material selection accuracy of the limiting plate 301 needs to be improved. In the embodiment, a three-dimensional model is constructed for the guide rail 1, the transport locomotive 2 and the derailment prevention mechanism 3 in the derailment prevention track conveying system, then the finite element analysis software is used for carrying out stress analysis on the guide rail 1, the transport locomotive 2 and the derailment prevention mechanism 3, finally the stress parameter of the limiting plate 301 in the full-load state of the transport locomotive 2 is obtained, and then the material is selected according to the stress parameter, so that the accuracy of material selection and the reliability of the system after operation are greatly improved.
The derailment-prevention track conveying system based on finite element analysis that this embodiment provided possesses following advantage:
firstly, an anti-derailing mechanism 3 is additionally arranged on a transport locomotive 2 to reduce the derailing risk of the transport locomotive 2 and improve the safety during construction;
secondly, the energy conversion assembly 4 is arranged to recycle the kinetic energy of the axle 201 of the conveyor, so as to ensure stable power supply to the derailment prevention mechanism 3.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
