The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to protect all the changes and improvements within the scope of the present invention, and are not limited to the following examples;
the mine transport vehicle reversing limit alarm device comprises a girder 1 on a frame, a mechanical arm 3, a reset device, a conduction assembly and an alarm, wherein connecting pieces 2 are welded on two sides of the girder 1, the connecting pieces 2 are hinged with the top end of the mechanical arm 3 through a first pin shaft 7, the mechanical arm 3 can swing by taking the first pin shaft 7 as a center, the reset device is arranged between the girder 1 and the mechanical arm 3, the girder 1 and the mechanical arm 3 are provided with the conduction assembly, and the conduction assembly is electrically connected with the alarm in a cab; the alarm is powered by a storage battery of the vehicle, and the on or off of the conducting assembly is controlled by the mechanical arm 3.
Specifically, the conducting assembly comprises a limit switch 9 arranged on the inner side of the girder 1 and a transverse plate 8 fixed on the side surface of the upper end of the mechanical arm 3, and a pull rod of the limit switch 9 is fixed on the transverse plate 8; in another mode, the pull rod is not arranged on the transverse plate 8, and when the transverse plate 8 swings along with the mechanical arm 3, the transverse plate 8 can press the pull rod, so that the limit switch 9 is switched on.
Specifically, resetting means is equipped with second spring 5 including being located the coupling assembling on girder 1 and arm 3 between the coupling assembling.
As can be seen from the above, the pull rod of the limit switch 9 is fixed on the transverse plate 8 on the side surface of the mechanical arm 3, if the limit switch 9 is in the off state, the transverse plate 8 cannot move relative to the limit switch 9, that is, the mechanical arm 3 cannot move relative to the girder 1, which requires that the top surface of the mechanical arm 3 is almost parallel to a large number of the girders 1, which is called that the state is the balanced state, and in the balanced state, the limit switch 9 is in the off state, that is, the conducting assembly is in the off state, and at this time, the alarm cannot give an alarm to the driver;
under the condition that the mechanical arm 3 is free from any external force, the mechanical arm 3 cannot reach the balance due to the action of the first pin shaft 7, so that the second spring 5 is required to exert a pulling force on the mechanical arm 3 to overcome the self gravity of the mechanical arm, and the type selection of the specific second spring 5 can be selected according to the self weight of the mechanical arm 3.
The whole device can be statically balanced only in the presence of the return means, i.e. the second spring 5, which is the open circuit condition of the conducting assembly, and the alarm does not alert the driver.
The number of the crossbeams 1 on the frame is basically two, the mechanical arm 3 is positioned below the crossbeam 1, so that the swinging angle of the mechanical arm 3 can be limited, after the mechanical arm 3 swings to a certain degree, the end part, close to the first pin shaft 7, of the mechanical arm 3 can be jacked to the crossbeam 1, the mechanical arm 3 cannot swing any more, and meanwhile, the limit switch 9 can be protected due to the limited swinging amplitude of the pull rod of the limit switch 9; a plurality of third springs 6 are transversely arranged between the mechanical arms 3, rolling stones are generated at the rear tail part of the vehicle when the vehicle backs, the rolling stones collide against the third springs 6 after rolling off, the third springs 6 can pull the mechanical arms 3 on any side open, the mechanical arms 3 can swing similarly, the transverse plate 8 is further driven to move downwards, the pull rod of the limit switch 9 is downward, the limit switch 9 is switched on, and the alarm gives an alarm to a driver; in addition, if only one side of the mechanical arm 3 touches the rear earth wall and the other side of the mechanical arm 3 does not touch, the third spring 6 can also pull the mechanical arm 3 which does not touch the earth wall to act, so that the alarm can give an alarm as long as one limit switch 9 can work.
The mechanical arm 3 can also be in a two-section type and comprises an upper mechanical arm 31 and a lower mechanical arm 32 which are hinged through a second pin shaft 33, the second pin shaft 33 is positioned at one end far away from the first pin shaft 7, and a connecting assembly of a second spring 5 is arranged above the second pin shaft 33.
The side surfaces, far away from the second pin shaft 33, of the upper mechanical arm 31 and the lower mechanical arm 32 are longitudinally provided with the first spring 4, two ends of the first spring 4 are respectively fixed on the upper mechanical arm 31 and the lower mechanical arm 32, and the first spring 4 can ensure that the lower mechanical arm 32 cannot be thrown back and forth in a mess under normal conditions.
The upper mechanical arm 31 includes a trapezoidal upper portion 312 and a rectangular lower portion 311, and a through pin hole is formed in a side surface of the upper portion 312 to accommodate the first pin 7.
The lower mechanical arm 32 is L-shaped, the baffle 34 is arranged at the tail end of the lower mechanical arm 32, when the baffle 34 touches the soil wall, the whole mechanical arm 3 breaks the original balance, starts to swing by taking the first pin shaft 7 as the center, at the moment, the component is conducted to open the circuit, the alarm gives an alarm, after unloading is completed, the vehicle is opened forwards, the baffle 34 is separated from the soil wall, returns to the balance position again under the action of the second spring 5, the component is conducted to open the circuit, and the alarm stops giving an alarm.
The details of the above are not described in detail since they are prior art.
