[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the railway maintenance machine chassis of an embodiment of the utility model comprises a box body 1, a bearing plate 2 is arranged inside the box body 1, a receiving groove 11 is arranged on the inner wall of one side of the box body 1, and an adjustment component 3 is arranged in the receiving groove 11. Figure 4 As shown, the adjustment assembly 3 includes a first screw 31, a first bevel gear 32 and a second bevel gear 33. The first screw 31 passes through the supporting plate 2 and is threadedly connected to the supporting plate 2. The first bevel gear 32 is arranged at one end of the first screw 31 and meshes with the second bevel gear 33. A knob 4 is also provided on the outer wall of the box body 1, and the knob 4 is connected to the second bevel gear 33.

[0027] By rotating the knob 4 on the outer wall of the box body 1, the second bevel gear 33 can be driven to rotate, and the second bevel gear 33 drives the first bevel gear 32 and the first screw 31 to rotate, so that the supporting plate 2 arranged on the first screw 31 moves along the first screw 31, and a space of appropriate size can be created above and below the supporting plate 2 according to the size of the network equipment to be placed, so as to meet the installation requirements of network equipment of different sizes.

[0028] like Figure 4 As shown, the bearing plate 2 includes a plate body 21 and a protrusion 22 disposed on one side of the plate body 21, the first screw rod 31 passes through the protrusion 22, and the protrusion 22 is disposed in the receiving groove 11. The protrusion 22 is inserted into the receiving groove 11, and when the bearing plate 2 moves, the protrusion 22 moves in the receiving groove 11, so that the groove wall of the receiving groove 11 limits the protrusion 22, which can improve the stability of the bearing plate 2 when moving.

[0029] like Figure 3 and Figure 5 As shown, a clamping assembly 5 is provided on the carrier plate 2 and at the bottom of the box body 1. The clamping assembly 5 includes a fixed plate 51, a movable plate 52, a second screw 53, an elastic member 54 and a clamping plate 55. The fixed plate 51 is fixed on the carrier plate 2. The second screw 53 passes through the fixed plate 51 and is threadedly connected to the fixed plate 51. The movable plate 52 is arranged on one side of the fixed plate 51 and is connected to one end of the second screw 53. One end of the elastic member 54 is connected to the movable plate 52, and the other end of the elastic member 54 is connected to the clamping plate 55. By screwing the second screw 53, the second screw 53 can be moved on the fixed plate 51, thereby driving the movable plate 52 away from or close to the fixed plate 51, so that the clamping plate 55 is away from or close to the fixed plate 51. With the buffering effect provided by the elastic member 54, it can stably press against one side of the network device to achieve fixation, and can adapt to network devices of different sizes.

[0030] Furthermore, the clamping assembly 5 further includes a guide member 56, which passes through the fixed plate 51 and is connected to the movable plate 52. The guide member 56 moves synchronously with the movable plate 52, and a guide member 56 is provided on both sides of the second screw rod 53, so that the movable plate 52 can move more smoothly and always maintain a parallel state with the fixed plate 51 during its movement.

[0031] Furthermore, a limiting ring 57 is provided at one end of the guide member 56 away from the movable plate 52 . The limiting ring 57 can prevent the guide member 56 from being separated from the fixed plate 51 , thereby improving the reliability of the clamping assembly 5 .

[0032] like Figure 5 As shown, a screwing portion 58 is provided at one end of the second screw rod 53 away from the movable plate 52. The screwing portion 58 is provided for manual screwing, so that the second screw rod 53 is easier to operate and can prevent the second screw rod 53 from being separated from the fixed plate 51.

[0033] like Figure 4 As shown, a partition 6 is provided in the box body 1, and the partition 6 is spaced apart from the inner wall of the box body 1, and a heat dissipation component 7 is provided between the partition 6 and the inner wall of the box body 1, as shown in FIG. Figure 1 and Figure 3 As shown, the partition plate 6 and the box body 1 are respectively provided with a first heat dissipation hole 61 and a second heat dissipation hole 12. The heat dissipation assembly 7 enables the air inside the box body 1 to exchange with the outside air through the first heat dissipation hole 61 and the second heat dissipation hole 12, thereby taking away the heat generated by the network equipment inside the box body 1, so that the network equipment can be effectively cooled and its normal operation is guaranteed.

[0034] like Figure 1 As shown, a filter 13 is provided on the second heat dissipation hole 12. The filter 13 can prevent insects or other foreign objects from entering the box body 1 without hindering the normal flow of air, thereby providing a good operating environment for the equipment inside the box body 1.

[0035] like Figure 1 As shown, the box body 1 further includes a handle 14 for easy movement, and a plurality of wire holes 15 are provided on one side of the box body 1 for wire harnesses to pass through.

[0036] like Figure 6 and Figure 7 As shown, the heat dissipation assembly 7 includes a ventilation pipe 71, a support frame 72, a rotating shaft 73, a fan blade 74 and a driving member 75. The two ends of the ventilation pipe 71 are respectively arranged on the first heat dissipation hole 61 and the second heat dissipation hole 12. The support frame 72 is arranged inside the ventilation pipe 71. The rotating shaft 73 is installed on the support frame 72. The fan blade 74 is installed on the rotating shaft 73. The driving member 75 is connected to the rotating shaft 73 and drives the rotating shaft 73 to rotate. The ventilation pipe 71 not only serves as an air circulation duct, but also provides an installation position for the support frame 72. The support frame 72 is cross-shaped, which can keep the rotating shaft 73 stable. The driving member 75 rotates the fan blade 74 by driving the rotating shaft 73 to rotate, thereby promoting air flow. In order to achieve smooth air exchange, two partitions 6 are arranged inside the box 1, and each partition 6 is provided with a heat dissipation assembly 7. One heat dissipation assembly 7 blows air into the box 1, and the other blows air to the outside of the box 1.

[0037] Specifically, the driving member 75 includes a motor 751, a driving wheel 752, a belt 753 and a driven wheel 754. The motor 751 is arranged on the partition 6, the driving wheel 752 is arranged at the output end of the motor 751, the driven wheel 754 is arranged on the rotating shaft 73, the belt 753 is arranged on the driving wheel 752 and the driven wheel 754, and the ventilation pipe 71 is provided with a through hole 711 for the belt 753 to pass through. This structure enables one driving member 75 to drive two fan blades 74 to rotate at the same time. The two fan blades 74 are arranged at intervals, so that the air inside the box 1 can be more fully circulated, and a better heat dissipation effect can be achieved.

[0038] like Figure 1 As shown, a base 8 is further provided below the box body 1, and the base 8 is connected to the box body 1 through a connector 9. A cavity is provided inside the base 8, so that the bottom of the box body 1 can dissipate heat well, and the bottom of the base 8 has a larger area than the bottom of the box body 1, so that the railway maintenance machine chassis can be placed on the railway maintenance machine more stably.

[0039] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
