A safety protection mechanism for a ring rail car

Abstract

This utility model discloses a safety protection mechanism for a circular track vehicle. A center of gravity adjustment device is installed at the bottom of the track vehicle. When the track vehicle encounters a tilt while turning, a linear motor drives the counterweight to shift and offset the overturning moment, ensuring the safety of the track vehicle. In case of an emergency requiring the track vehicle to stop immediately, an emergency stop device is activated. The piston rod of the hydraulic cylinder pushes the mounting plate in front of the moving track vehicle to stop it. The honeycomb plate and rubber plate play a buffering role. By setting up a purging device, the high-speed air blown by the high-speed fan is further compressed by the high-pressure purging nozzle and then blows the contact surface between the track and the driving and driven wheels to remove dust and other substances generated by the friction between the driving and driven wheels and the track, avoiding the long-term accumulation of dust and other substances that may affect the safety of the track vehicle.

Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a safety protection mechanism for a circular rail vehicle. Background Technology

[0002] A circular railcar is a type of transportation that runs on a closed circular track. Its core characteristic is that the track is circular (circular, elliptical, or other closed shapes), and the vehicle travels in a loop along a fixed route. In industrial applications, circular railcars are generally used for loading materials. Current circular railcar technology only considers safety issues from the perspective of braking, and its safety protection is not comprehensive.

[0003] Therefore, it is necessary to develop a safety protection mechanism for a circular track vehicle to solve the above problems. Utility Model Content

[0039] Mounting plate; A groove is provided laterally at the bottom of the body 6 of the railcar 2, and the mounting plate is installed at the bottom of the groove and along the length of the groove;

[0040] Bearing housing 14;

[0041] Linear motor 15; bearing housing 14 and linear motor 15 are respectively mounted on the lower ends of the mounting plate;

[0042] Screw 16; The first end of screw 16 is connected to the shaft of linear motor 15, and the second end of screw 16 is rotatably mounted on bearing seat 14;

[0043] Movable block 17; Movable block 17 is provided with a screw hole and two through holes, which are arranged in parallel; Screw 16 is threadedly engaged with the screw hole on movable block 17;

[0044] Counterweight 18; Counterweight 18 is installed at the bottom of the moving block 17;

[0045] Two guide rods 19; the two guide rods 19 are respectively guided and engaged with two through holes on the moving block 17, and the two ends of the guide rods 19 are respectively installed on the housing of the linear motor 15 and the bearing seat 14, and the two guide rods 19 are parallel to the screw 16.

[0046] like Figure 1 and 2 As shown, the safety protection mechanism of the circular track vehicle 2 also includes a blowing device 3 for blowing away dust on the track 1, and the blowing device 3 is installed at the rear of the track vehicle 2.

[0047] like Figure 2 As shown, the purging device 3 includes two high-speed fans 10 and two high-pressure purging nozzles 11. The high-speed fans 10 are installed at the rear of the railcar 2, and the air outlets of the high-pressure purging nozzles 11 are set close to the contact surface between the rail 1 and the railcar 2.

[0048] In some embodiments, a purging device 3 may be installed at the front of the railcar 2 to purge the track 1 in the direction of travel.

[0049] like Figure 1 As shown, the safety protection mechanism of the circular track vehicle 2 also includes multiple emergency stop devices, which are evenly distributed along the track 1.

[0050] like Figure 1 and 6 As shown, each emergency stop device includes two sets of sub-emergency stop devices, which are installed on opposite sides of the track 1. Each set includes an upper slide rail 5, an upper sliding plate 21, an impact plate 20, a lower slide rail 22, and a lower sliding plate 23. The upper and lower ends of the impact plate 20 are connected to the upper sliding plate 21 and the lower sliding plate 23, respectively. Both the upper slide rail 5 and the lower slide rail 22 are provided with grooves. The upper sliding plate 21 is slidably installed in the groove of the upper slide rail 5, and the lower sliding plate 23 is slidably installed in the groove of the lower slide rail 22. The upper slide rail 5, the lower slide rail 22, and the impact plate 20 are all perpendicular to the track 1.

[0051] like Figure 6 As shown, the sub-emergency stop device also includes a honeycomb plate 24 and a rubber plate 25. The honeycomb plate 24 is installed on the front side of the impact plate 20, and the rubber plate 25 is installed on the front side of the honeycomb plate 24.

[0052] like Figure 6 As shown, the grooves in both the upper slide rail 5 and the lower slide rail 22 are T-shaped grooves. The purpose of the T-shaped grooves is to provide better guidance for the upper sliding plate 21 and the lower sliding plate 23.

[0053] like Figure 1As shown, the emergency stop device also includes a hydraulic cylinder 4. The piston rod of the hydraulic cylinder 4 is connected to the outer end of the impact plate 20, and the piston rod of the hydraulic cylinder 4 is perpendicular to the rail 1. In some embodiments, the piston rod of the hydraulic cylinder 4 is not rigidly connected to the impact plate 20, which can prevent the hydraulic cylinder 4 from being damaged if the impact plate 20 is damaged. The impact plate 20 is a replaceable part, which can be removed and replaced after one use. After the impact plate 20 has finished its work, if it is not damaged, it can be manually pushed back to its original position.

[0054] like Figure 1 and 3 As shown, track 1 is a single track. Two parallel drive wheels 8 are located at the front lower part of the track vehicle 2. The drive wheels 8 are connected to the shaft of a drive wheel motor 7 installed inside the track vehicle 2. Two parallel driven wheels 9 are located at the rear lower part of the track vehicle 2. The two drive wheels 8 and the two driven wheels 9 are respectively able to roll and clamp onto the track 1. The track vehicle 2 in this embodiment has a built-in braking system, but this is prior art and will not be described in detail here.

[0055] Working principle: During operation, the drive wheel motor 7 drives the drive wheel 8 to rotate. Because the drive wheel 8 is in rolling friction contact with the track 1, it propels the railcar 2 forward. The driven wheel 9 acts as a limit stop and assists in forward movement. During this time, the high-speed fan 10 is constantly operating. The high-speed air blown out is further compressed by the high-pressure purging nozzle 11 and then purifies the contact surface between the track 1 and the drive wheel 8 and driven wheel 9, removing dust and other substances generated by friction between the drive wheel 8 and driven wheel 9 and the track 1. This prevents the long-term accumulation of dust and other substances from affecting the safety of the railcar 1. When the railcar 2 turns a curve... When the linear motor 15 is working, it drives the screw 16 to rotate. Because the guide rod 19 limits the axial rotation of the moving block 17, the moving block 17 and the counterweight 18 move towards the inside of the curve along the length of the screw 16, offsetting part of the overturning moment of the railcar 2. When an emergency occurs and the railcar 2 needs to stop immediately (for example, when there is a person or object on the track 1 ahead that cannot be avoided), the emergency stop device works. The piston rod of the hydraulic cylinder 4 pushes the impact plate 20 to the front of the moving railcar 2 to stop the railcar 2. The honeycomb plate 24 and the rubber plate 25 play a buffering role.

[0056] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
