The sanding system of the SS4G electric locomotive consists of a sand box, a sander, an air pipe, a bobbin, a horseshoe sleeve and the like, and the sanding device is an important component of the electric locomotive. When the operating conditions of the locomotive are severe, such as stormy weather, the adhesion coefficient of the locomotive changes, and the locomotive is easy to idle. Idling has a great influence on the clamping control of locomotives, steel rail lines and running time. In bad weather, if the idling is to be changed, the sanding system plays a crucial role, and the sand can change the adhesion coefficient between the wheel tracks, so that the idling is changed.

Sanding systems are required for the addition of sand which must be dry, free of paper sheet plastic impurities, must not be contaminated with small stones over 3mm in diameter, etc. When the added sand does not accord with the rules, the sanding system will be blocked, at the moment, the sand in the sand box can only be cleaned, and the normal function of the sanding system can be recovered after the impurities are manually removed.

The sand discharging port of the sand box is fastened by a screw with the diameter of 20mm and the length of 50mm, when sand is discharged, the sand can be stuck on the thread of the sand box, so that the sand is difficult to install after the sand is discharged, the sand in the thread of the sand box is difficult to clean, and the sand can be difficult to clean. If the sand plug is installed insecurely, the sand plug becomes looser and looser due to vibration during the operation of the locomotive and is finally lost, sand in the sand box can be completely discharged at the moment, an embarrassing situation that no sand can be used when the sand is used is formed, and even the result of stopping the locomotive in an interval is caused.

The utility model provides a pair of embodiment: the utility model provides a quick sand discharging device of sand box, includes that nut 3 seals, deep income ware 1 and with deep ware 1 coaxial hollow round platform stud 2 that sets up as an organic whole, hollow round platform stud 2 include round platform 2.1 on upper portion and the stud part 2.2 of lower part, hollow round platform stud 2 axial inside has the sand outlet channel 2.3 of trompil shape, round platform 2.1 bottom diameter and the equal diameter of stud part 2.2 external diameter, stud part 2.2 in be provided with integrative dog 2.4 on the upper portion outer wall, dog 2.4 divide into stud part 2.2 and last stud 2.21 and lower stud 2.22, round platform 2.1 on open and have the sand inlet 2.5 of a plurality of symmetry settings, sand inlet 2.5 extends to the lower extreme of stud 2.21 along the round platform outer wall downwards, sand inlet 2.5 and sand outlet channel 2.3 intercommunication, the stud part 2.2 lower extreme is connected with nut 3.

Referring to fig. 1, 2 and 3, in the present embodiment, the deep driver 1 is a solid flat-long circular truncated cone with a taper. The main function of the depth-entering device 1 is to reduce the resistance of sand on the upper part of the sand plug when the sand plug is installed before the sand in the sand box is not completely discharged, and to puncture a sand wall (the principle is similar to the puncturing of an air wall), so that the sand plug can enter easily.

The outer wall of the circular truncated cone 2.1 is smooth, the circular truncated cone 2.1 is provided with a square sand inlet hole 2.5 which extends downwards to the lower end of the upper threaded column 2.21 along the side wall, sand at the thread part of the upper threaded column 2.21 on the circular truncated cone 2.1 and in threaded connection with the sand box can enter the sand outlet channel 2.3 through the sand inlet hole 2.5 and flow out of the sand outlet hole 2.31, and the problems that the sand plug is difficult to install, the sand in the threads of the sand box is difficult to clean, the sand plug is buckled when the sand box is installed violently, and even the threads of the sand box are buckled are solved. The smooth outer wall of the circular truncated cone 2.1 enables sand to be attached to the outer wall of the circular truncated cone 2.1 under the action of gravity, so that the contact surface for sand falling under the sand is increased, the sand flows down rapidly, and the sand discharging speed is accelerated; in the embodiment, 3 sand inlet holes 2.5 are arranged on the outer wall of the circular truncated cone 2.1 at intervals, the 3 sand inlet holes 2.5 are arranged at an included angle of 120 degrees, and the corresponding number can be selected according to the specification;

the stop block 2.4 is used for dividing the sand discharging device into two parts, one part comprises a deep feeder 1, a round table 2.1 and an upper threaded column 2.21, the deep feeder 1 and the round table 2 are inserted into a sand box, the upper threaded column 2.21 is fixedly connected with the sand box in a threaded manner, the part does not need to be disassembled in the process of discharging sand under normal conditions, sand can be discharged only by disassembling the sealing nut 3 below the stop block 2.4, on one hand, the working time is saved, and on the other hand, the problems of screw sliding and buckling and the like caused by frequent disassembly are avoided; the stop block 2.4 selected in the embodiment is a nut fixedly sleeved or welded on the outer side wall of the middle upper part of the hollow circular truncated cone stud 2, and other fixing plate devices can be selected, so that sand does not flow downwards through the stop block 2.4.

The lower end thread of the lower threaded column 2.22 is connected with a sealing nut 3, and the sealing nut 3 is used for dismounting the lower threaded column to start sand discharging when sand discharging is carried out; and after the sand is put, the sand outlet 2.31 of the lower threaded column 2.22 is blocked by the sealing nut 3. The lower end of the inner side thread of the sealing nut 3 in the embodiment is provided with the inverted-triangular sand containing chamber 3.1 for containing redundant sand, so that the sand is prevented from entering the inner thread at the bottom end of the sealing nut 3, the sealing nut 3 is prevented from being connected unstably, and the screw is buckled in a sliding manner and is easy to lose. In addition, in order to further solve the problem, a pin hole 4 is formed at the joint of the sealing nut 3 and the lower threaded column 2.22, and after the sealing nut 3 is installed, a cotter pin is installed in the pin hole 4, so that the connection between the sealing nut 3 and the lower threaded column is further strengthened.

The method comprises the following specific installation steps:

1. inserting the deep driver 1 into the sand box, and screwing the upper thread column 2.21 on the internal thread of the sand box; (due to the sand inlet hole, the sand on the thread enters the sand outlet channel 2.3 in the rotating process, and the connection sliding buckle is not caused)

2. The sealing nut 3 is screwed on the lower threaded column 2.22 and then fixed through the cotter pin;

3. when the sand is put, the upper threaded column 2.21 is kept fixed on the sand box, the split pin is only needed to be disassembled, the connection between the sealing nut 3 and the lower threaded column 2.22 is unscrewed, and the sand enters the sand outlet channel 2.3 through the sand inlet hole 2.5 and flows out of the sand outlet 2.31;

4. after the sand is put, the sealing nut 3 is screwed again, and then the sealing nut 3 and the lower threaded column 2.22 are fixed through the cotter pin.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
