Description

Technical Field

[0001] The utility model discloses a vibration box, belonging to the field of railway maintenance equipment, in particular to a vibration box. Background Art

[0002] Due to the rolling action of running vehicles, the ballast track bed will deform and sink. In order to restore the smoothness of the line and ensure the safe and high-speed operation of trains, tamping operations need to be carried out regularly. Therefore, tamping operations are an important part of railway line maintenance operations.

[0003] The vibration box is one of the important components of the railway line maintenance tamping equipment. It relies on the high-speed rotation of the eccentric iron set on the vibration box to generate vibration, providing the tamping equipment with the exciting force required for the tamping operation. The tamping exciting force requires a certain vibration frequency. Therefore, under the exciting force frequency requirement, the bearings of the vibration box need to run at high speed. The vibration plus high-speed operation makes the working conditions of the bearings used in the vibration box poor, and the bearings are easy to heat up. The existing vibration box bearings have no forced heat dissipation function and can only rely on the natural heat dissipation function of the box surface for heat dissipation. The long-term high-speed operation plus vibration working conditions make the bearings used in the vibration box in an overheated state for a long time, causing the bearings to become vulnerable parts on the component and become one of the main failure points on the tamping equipment. In addition, the tamping pick body is installed on the vibration box, so the vibration box body must also bear the clamping force generated by the tamping pick body, which requires the vibration box body to have sufficient strength. The cantilever tamping pick body bearing shaft used in the existing vibration box body is also one of the failures that cause damage to the vibration box body. Utility Model Content

[0018] The shaft reinforcement plates respectively arranged on the inner side between the connecting shafts at both ends of the vibration box can effectively improve the force bearing capacity in the inner direction of the connecting shafts at both ends and avoid the breakage of the shaft ends.

DETAILED DESCRIPTION

[0030] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 10 The utility model is further described.

[0031] Embodiment 1:

[0032] Reference Figures 1 to 4 The vibration box includes a vibration box body 1, a sealing baffle 2, a vibration shaft 3, a bearing 4, an eccentric block 5 and a pulley 6. Bearings 4 are arranged between both ends of the vibration shaft 3 and the vibration box body 1. The vibration shaft 3 is provided with a pulley 6 as a power transmission component, and the eccentric block 5 is fixed on the vibration shaft 3. The vibration box body 1 is provided with heat dissipation holes 7, and a plurality of heat dissipation holes 7 are evenly distributed on the outside of the bearing 4.

[0033] The vibration box 1 includes two frame plates 9 arranged parallel to each other, a connecting shaft 10, a reinforcing rib plate 8 and a shaft reinforcing plate 15. The two ends of the two frame plates 9 are connected by the connecting shaft 10 respectively. The shaft reinforcing plate 15 is horizontally arranged between the two ends of the connecting shaft 10 and the frame plates 9 to prevent the two ends of the connecting shaft 10 from being suspended and broken. The two reinforcing rib plates 8 are fixed between the two frame plates 9, and the two reinforcing rib plates 8 are symmetrically distributed on both sides of the vibration shaft 3. The heat dissipation holes 7 are arranged on the inner sides of the two reinforcing rib plates 8. The spacing between the two reinforcing rib plates 8 is narrow at the top and wide at the bottom.

[0034] Bearings 4 are provided between both ends of the vibration shaft 3 and the vibration box 1. The bearings 4 are arranged in the middle of the two frame plates 9, and the vibration shaft 3 is connected with the bearings 4. Sealing baffles 2 are provided on the inner and outer sides of the bearing 4. The sealing baffles 2 are fixed on the frame plate 9 of the vibration box 1, and are used to seal and fix the bearing 4. The sealing baffles 2 are provided with a sealing oil filling port 17 for filling grease, which is used to fill grease for the bearing 4. The heat dissipation holes 7 are evenly distributed on the outside of the bearing 4. The end of the vibration shaft 3 is provided with a power transmission component pulley 6, which is located on the outside of the frame plate 9 of the vibration box 1. A fixed sleeve 13 is provided on one side of the pulley 6, and the other end of the fixed sleeve 13 is connected to one side of the inner ring of the bearing 4. The end of the vibration shaft 3 is connected with a fixing bolt 12, and the fixing bolt 12 presses the other side of the pulley 6 through the pressure plate 14. The pulley 6 is connected to the power component through a belt, thereby driving the vibration shaft 3 to rotate.

[0035] Two eccentric blocks 5 are installed side by side in the middle of the vibration shaft 3. One side of the vibration shaft 3 is provided with a shaft shoulder for fixing the eccentric block 5, and the other side is provided with a fixed sleeve 13. One end of the fixed sleeve 13 is connected to the eccentric block 5, and the other end is connected to one side of the inner ring of the corresponding side bearing 4. The end of the vibration shaft 3 is connected with a fixing bolt 12, and the fixing bolt 12 is pressed on the other side of the inner ring through a pressure plate 14. When the vibration shaft 3 rotates, the eccentric block 5 generates vibration through the rotation of the eccentric block 5, thereby achieving a vibration effect.

[0036] In addition to strengthening the strength of the vibration box 1, the reinforcing rib plate 8 can also assist the heat dissipation holes 7 in dissipating heat. During the high-speed rotation of the vibration shaft 3, the high-speed operation and vibration cause the bearing 4 to generate a large amount of heat. When the operating temperature of the bearing 4 is too high, the grease added to the bearing 4 is easy to be lost. The loss of grease causes the bearing lubrication effect to deteriorate, and then the high-speed bearing 4 generates heat faster. Such a vicious cycle can easily cause damage to the bearing 4. During the operation, the eccentric block 5 plays the role of a single-blade fan, and the reinforcing rib plate 8 plays the role of strengthening the airflow, so that the generated wind passes through the heat dissipation holes 7, effectively dissipating the heat of the bearing 4, avoiding the bearing from entering the high-temperature area where grease is lost during operation, and achieving the effect of extending the service life of the bearing 4.

[0037] Embodiment 2:

[0038] Reference Figures 5 to 7 , the difference between this embodiment and embodiment 1 is that: in this embodiment, two eccentric blocks 5 are respectively arranged at the two ends of the vibration shaft 3, and are located on the outside of the frame plate body 9 of the vibration box body 1. At one end with the pulley 6, the eccentric block 5 and the pulley 6 form a whole, the pulley 6 is on the inside, close to the vibration box body 1, and the eccentric block 5 is on the outside, so that the airflow generated by the eccentric block 5 is blocked by the pulley 6, and a plurality of heat dissipation blades 11 corresponding to the position of the heat dissipation hole 7 are arranged on the side of the pulley 6 close to the vibration box body 1, and the heat dissipation blades 11 are fixed on the pulley 6. The rotation of the pulley 6 allows the airflow generated by the heat dissipation blades 11 to directly enter the heat dissipation hole 7, thereby realizing heat dissipation of the bearing 4. The eccentric block 5 at the other end is fixed on the vibration shaft 3, and the airflow generated by the rotation of the eccentric block 5 effectively dissipates the heat of the bearing 4 through the heat dissipation hole 7 and the reinforcing rib plate 8.

[0039] Embodiment 3:

[0040] Reference Figures 8 and 9 The difference between this embodiment and embodiment 1 is that: in this embodiment, the vibration box is used for a machine model that only needs to install a tamping pick body on one side, such as a turnout machine. Both ends of the two frame plates 9 of the vibration box body 1 are fixedly connected with mounting plates, and both ends of the frame plates 9 are respectively fixed with connecting shafts 10. Since models such as turnout machines only need to install a tamping assembly on one side, in this embodiment, only one end of the connecting shaft 10 extends out of the frame plate 9.

[0041] Embodiment 4:

[0042] Reference Fig.10 The difference between this embodiment and embodiment 1 is that in this embodiment, in order to reduce the weight of the vibration box, a plurality of lightening holes 16 are provided on the two frame plates 9 of the vibration box body 1.
