Railway freight has the characteristics of large transportation volume, long transportation distance, relatively low transportation cost and relatively short transportation time. Railway freight is an important way of transporting coal in my country. Railway freight generally uses open carriages for transportation. When transporting coal, railway freight needs to monitor the speed of freight trains. One of the reasons for measuring the speed of freight trains is that, as mentioned in the authorization announcement number CN209946186 U "Fixed Dust Suppression Equipment Train Speed ​​Monitoring Device", in order to make freight trains better cooperate with dust suppression equipment to avoid coal dust flying everywhere;

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figure 1 to Figure 5 As shown, a railway freight speed measuring device comprises a vertical pole 1 and a bearing member; the vertical pole 1 is a round rod body, and the upper and lower ends of the vertical pole 1 are connected with a cross plate 2, and the two cross plates 2 are rectangular plates and are opposite to each other up and down; the bearing member comprises a bearing ring 3, a bearing plate 4 and a control component, the bearing ring 3 is a circular ring plate, and the right part of the bearing ring 3 is slidably sleeved on the outside of the vertical pole 1 through a through hole 11, and the through hole 11 is a circular hole in sliding contact with the vertical pole 1, and the bearing plate 4 is rotatably connected inside the bearing ring 3, and the bearing plate 4 is a circular plate body whose circumferential surface slides in contact with the inner ring of the bearing ring 3, and the bottom surface of the bearing plate 4 is connected to a speed measuring device, and a threaded barrel 5 is connected to the middle part of the bearing plate 4, and the threaded barrel passes through and is fixedly connected to the bearing plate, and a screw 6 is threadedly connected to the threaded barrel 5, and the lower end of the screw 6 is rotatably connected to the lower side The horizontal plate 2 and the upper end are driven to rotate by the motor 7; the control component includes a hemisphere 8, a control board 9 and a push rod 10, the bulge of the hemisphere 8 faces upward, the middle part of the hemisphere 8 is sleeved on the outside of the screw 6 through the second through hole 12, and the bottom surface is connected to the upper end of the threaded barrel 5, the control board 9 is a circular plate with a diameter greater than the diameter of the bearing plate 4, the middle part of the control board 9 is slidably sleeved on the outside of the threaded barrel 5 through the third through hole 13, the third through hole 13 slides in contact with the threaded barrel 5, the control board 9 is adjusted to move upward or downward by the second screw 25, one end of the push rod 10 is located outside the control board 9, and the other end passes through the control board 9 to contact the threaded barrel 5, the end of the push rod 10 outside the control board 9 is connected with a baffle 14, and the baffle 14 and the control board are connected with a spring 16 sleeved on the outside of the push rod 10; the control board 9 is provided with a through hole 17 for the push rod 10 to slide through.

[0024] The motor 7 is fixed on the top surface of the upper horizontal plate 2 with the output end facing downward. The upper end of the screw 6 passes through the upper horizontal plate 2 to connect the output end of the motor 7. The model of the motor 7 selected by the utility model is F5D200-24GU-18S, and the output shaft of the motor can be rotated forward and reverse.

[0025] There is a distance between the control plate 9 and the vertical pole 1; there is a distance between the upper end of the bearing plate 4 and the upper end of the bearing ring 3, an annular groove 18 is provided on the circumferential surface of the bearing plate 4, and a limiting rod 19 is installed on the bearing ring 3, and the limiting rod 19 passes through the outer ring and the inner ring of the bearing ring 3 in sequence and extends into the annular groove 18, the limiting rod is fixedly connected to the bearing ring, and one end of the limiting rod extending into the annular groove 18 is in sliding contact with the annular groove 18.

[0026] The second screw 25 is threadedly connected to the control board 9, the lower end of the second screw 25 is rotatably connected to the bearing plate 4, and the upper end is connected to the rotating plate 20. The upper end of the second screw 25 is higher than the hemisphere 8. When the control board 9 is driven to move downward, the spherical surface of the hemisphere 8 is conducive to the contact between the push rod 10 and the outer wall of the threaded tube 5.

[0027] When the push rod 10 contacts the threaded barrel 5, the spring 16 is stretched to the limit state; when the control plate 9 is higher than the hemisphere 8, the push rod 10 contacts the screw rod 6, and the spring 16 is in a semi-stretched state.

The way in which the battery 22 and the speed measuring device 23 of the utility model are connected via the wire 24 is the same as the way in which the battery and the speed measuring device are connected via wires in CN209946186 U "Fixed dust suppression equipment train speed monitoring device".

[0029] When in use, when it is necessary to adjust the height of the speed measuring device, since the middle of the control plate 9 is limited, the control plate 9 can be controlled to move upward or downward by rotating the screw rod 25. The screw rod 25 is rotated to drive the control plate 9 to move downward until the bottom surface of the control plate 9 is tightly pressed against the bearing ring 3. Since the lower end of the screw rod 25 is connected to the bearing plate 4, the control component, the bearing plate 4 and the bearing ring 3 can be regarded as a whole at this time. Moreover, since the bearing ring 3 is limited by the vertical rod 1, when the motor 7 drives the screw rod 1 6 to rotate, the motor 7 drives the screw rod 1 6 to rotate forward to drive the threaded barrel 5 to drive the bearing plate 4 to move upward, and drives the screw rod 1 6 to rotate reversely to drive the threaded barrel 5 to move downward. When the screw rod 1 6 rotates, it can drive the control component, the bearing plate 4 and the bearing ring 3 to move upward or downward, thereby adjusting the height of the speed measuring device installed on the bearing plate 4.

[0030] When it is necessary to adjust the speed measuring angle of the speed measuring device, the screw rod 25 is rotated in the opposite direction to move the control plate 9 upward until the control plate 9 is higher than the hemisphere 8. When the control plate 9 moves upward, the control plate 9 no longer presses the bearing ring 3, and the push rod 10 can move upward with the control plate 9. When the control plate 9 is higher than the hemisphere 8, the spring 16 is in a semi-stretched state, and the push rod 10 presses the screw rod 6 tightly. Since the bearing plate 4 is connected to the control plate 9 via the screw rod 25, and since the push rod 10 on the control plate 9 presses the screw rod 6 tightly, at this time, the control component, the screw rod 6 and the bearing plate 4 can be regarded as a whole. The bearing plate rotates to connect the bearing ring. When the motor 7 drives the screw rod 6 to rotate, the control component and the bearing plate 4 rotate with the screw rod 6. The bearing ring will not rotate under the limit of the vertical pole, and the speed measuring device rotates with the bearing plate 4, thereby adjusting the speed measuring angle of the speed measuring device.

[0031] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
