Description

Technical Field

[0001] The invention relates to a short track speed skating leader, belonging to the technical field of short track speed skating training equipment. Background Art

[0002] The biggest resistance short track speed skaters face during skating comes from air resistance. During training, a team's lead skater skates into the wind, and the other skaters follow behind him. The lead skater is subject to the greatest air resistance, and a training team must have a fast lead skater to lead the skating so that the speed of other skaters in the team can be improved faster. If the athletes in the team are of similar level, it becomes very difficult to improve the speed together. However, since the lead skater does not have a faster athlete to lead the skating, it is difficult to improve his speed. Therefore, provincial and municipal athletes find it difficult to surpass high-level national team athletes because they do not have a high-level lead skater to lead the skating.

[0003] The leader's speed and trajectory are significantly limited by their individual ability, stamina, and physical condition on the day, as well as their understanding of the coach's instructional intent. Furthermore, it's impossible for a leader to achieve their ideal performance every time, making 100% execution of the coach's instructional intent impossible. This problem exists at the level of training teams at the provincial and municipal levels, as well as at the national short track speed skating team. The invention of a leader to replace human leaders could effectively address these issues. Summary of the Invention

[0031] like Figure 1-19 As shown, a short track speed skating leader includes a slide rail 1, an electric rail 2, a fixing frame Ⅰ3 and a leader.

[0032] The slide rail 1 is formed by connecting two parallel straight rails and two curved rails with equal radius. The cross section of the slide rail 1 is "I" shaped, and an electric rail 2 is installed on the inner side wall of the top horizontal plate of the slide rail 1.

[0033] The cross-sections of the two curved rails of the slide rail 1 are inclined inwards, which is beneficial to increasing the centripetal force of the slider. The electric rail 2 is composed of two C-shaped grooves and copper wires, and copper wires are arranged in the upper and lower C-shaped grooves.

[0034] The slide rail 1 is secured above the short-track speed skating track via a mounting bracket I3. This mounting bracket I3 can be a vertical pole, with the top end securing the slide rail 1 and the bottom end mounted on the ground, suspending the entire slide rail 1. Alternatively, the mounting bracket I3 can be an L-shaped rod, with the top end securing the slide rail 1 and the rear end secured to the stadium ceiling or wall, suspending the slide rail 1.

[0035] The slide rail 1 is provided with a sliding leader, which takes power from the electric rail 2 through the busbar collector 8. A forward drive motor 22 is provided inside the leader to drive it to slide on the slide rail 1. The leader is provided with a cantilever swing device 5. A leader slide plate 7 is installed below the cantilever swing device 5 through a cantilever 6. A cantilever drive motor 24 is provided inside the leader to drive the cantilever swing device 5. A PLC controller 26 is installed in the leader, and the PLC controller 26 is installed with V4.0.8.06 general software. The PLC controller 26 is connected to the PC host computer on the ground through the AB433A wireless 485 transparent transmission module. The PLC controller 26 takes power through the busbar collector 8. The motor drivers of the forward drive motor 22 and the cantilever drive motor 24 are both powered by the busbar collector 8 and controlled by the PLC controller 26. The speed and route data of the leader are transmitted to the PLC controller 26 through the PC host computer. The PLC controller 26 then drives the forward drive motor 22 through the motor driver to move the leader forward. During the forward movement, the PLC controller 26 drives the cantilever drive motor 24 through the motor driver to swing the leader skateboard 7. By leading the skateboard 7, the speed and route of the leader are simulated, which can effectively reduce the wind resistance of the athlete behind and improve training efficiency. The speed is controllable, and the athlete can always be ahead of the athlete, which helps to improve the comprehensive ability of the athlete.

[0036] The collar slider is composed of a collar slider housing 4, an air guide plate 10, a collar slider stabilizing device 11, a driving wheel 16, a driven wheel 17, a limiting wheel 18, a synchronous belt 19, a synchronous wheel 20, a differential 21, a forward drive motor 22, a fixing frame II 23, a cantilever drive motor 24, a pinion 25 and a PLC controller 26. The collar slider housing 4 is a U-shaped plate body, and a V-shaped air guide plate 10 is provided at the front end thereof. The V-shaped air guide plate 10 can effectively reduce the air resistance of the collar slider. Several air guide holes 9 are provided on the front end surface of the air guide plate 10. The air guide holes 9 can reduce the air resistance and play an air cooling role, thereby effectively cooling the internal components of the collar slider.

[0037] The collar slider box body 4 is located below the slide rail 1, and its two vertical plates are located on both sides of the slide rail 1. Driving wheels 16 are installed on the inner sides of the two vertical plates of the collar slider box body 4 through rotating shafts, and driven wheels 17 are provided behind the driving wheels 16. The driven wheels 17 are installed on the inner sides of the two vertical plates of the collar slider box body 4 through rotating shafts. The driving wheels 16 and driven wheels 17 on both sides are respectively located above the lower cross plates on both sides of the slide rail 1, and limiting wheels 18 are provided below the two driven wheels 17. The limiting wheels 18 are installed on the inner sides of the two vertical plates of the collar slider box body 4 through rotating shafts, and the limiting wheels 18 on both sides are respectively located below the lower cross plates on both sides of the slide rail 1; the entire collar slider uses its own weight to make the two driving wheels 16 and driven wheels 17 rest on the lower cross plate of the slide rail 1, ensuring that the driving wheel 16 rotates and the entire device moves forward. When the leader slider moves forward, the leader slide plate 7 at its bottom is subjected to huge wind resistance, driving the rear of the entire leader slider to tilt upward, and the limiting wheel 18 is located under the lower horizontal plate of the slide rail 1. In fact, the entire leader slider cannot tilt, thereby improving the stability of the entire device during movement.

[0038] A differential 21 is installed in the collar slider case 4 through a fixing frame II 23. The ends of the output shafts at both ends of the differential 21 are fixed to the inner walls on both sides of the collar slider case 4 through flange bearings. Synchronous wheels 20 are provided on the two output shafts of the differential 21. The two synchronous wheels 20 are connected to the drive wheels 16 through synchronous belts 19 respectively. The input shaft of the differential 21 is connected to the shaft end of the forward drive motor 22, and the forward drive motor 22 is fixed in the collar slider case 4. When the collar slider moves to the curved track of the slide rail 1, the driving force of the two drive wheels 16 changes due to centrifugal reasons, and the differential 21 can effectively adjust the power of the two drive wheels 16 to ensure smooth progress of the entire device.

[0039] A cantilever drive motor 24 is installed in the slider box 4, and a pinion 25 is provided at the shaft end of the cantilever drive motor 24. The cantilever drive motor 24 is connected to the cantilever swing device through the pinion 25. A PLC controller 26 is installed on the inner side wall of the slider box 4.

A slider stabilizing device 11 is installed on the inner side of the left vertical plate of the slider box 4, and a busbar collector 8 connected to the power rail 2 is installed on the side vertical plate of the slider box 4. The busbar collector 8 is connected to the PLC controller 26 through a wire; the forward drive motor 22 is a servo motor, and the cantilever drive motor 24 is a servo reduction motor with self-locking. The motor drivers of the forward drive motor 22 and the cantilever drive motor 24 are both powered by the busbar collector 8.

[0040] The cantilever swinging device 5 is composed of a swing shaft seat 27, a swing shaft 28, a rectangular tube 29, a fixing screw 30 and a gear plate 32. A rectangular hollow groove is provided at the bottom of the collar slider box 4, and a pair of swing shaft seats 27 are provided at the front and rear of the rectangular hollow groove. A swing shaft 28 is provided between the swing shaft seats 27, and a gear plate 32 is installed on the swing shaft 28. The top of the gear plate 32 is located in the collar slider box 4, and the gear plate 32 located in the collar slider box 4 is meshed with the pinion 25 at the end of the cantilever drive motor 24. A vertical downward rectangular tube 29 is provided on the gear plate 32, and the cantilever 6 is inserted into the bottom end of the rectangular tube 29. The rectangular tube 29 fixes the cantilever 6 through the fixing screw 30 screwed into the side wall; the cantilever drive motor 24 drives the gear plate 32 to rotate through the pinion 25, and the collar slide 7 fixedly connected to the gear plate 32 swings accordingly, thereby realizing the change of the collar slide trajectory.

[0041] The cross-section of the cantilever 6 is T-shaped, and the T-shaped rod can better resist bending deformation force. Wing plates 31 are provided on both sides of its bottom end. The wing plates 31 at the bottom end of the cantilever 6 are installed with a collar slide 7 through fixing screws 30. The collar slide 7 is a curved transparent plate; the curved surface can direct the wind from the front end of the collar slide 7 away, thereby improving the stability of the collar slide 7.

[0042] The busbar collector 8 is composed of a slider 12, a parallelogram link 13, a hinge seat 14, a tension spring 15 and a wiring copper column. The slider 12 is located on the power rail 2. A copper plate in contact with the copper wire of the power rail 2 is provided inside the slider 12. A wiring copper column connected to the copper plate is provided on the back of the slider 12. The wiring copper column is connected to the PLC controller 26 and the motor driver through a wire.

A tension spring 15 is provided between the adjacent two links of the parallelogram link 13, and the tension spring 15 drives the parallelogram link 13 to swing toward the power rail 2; ensuring that the entire device always remains energized.

[0043] The described collar slider stabilizing device 11 is composed of a guide wheel seat 33, a guide wheel 34, a leaf spring 35, a fixing rod 36, a rod sleeve 37 and a shaft column 38. Two sets of guide wheels 34 are provided on both sides of the "I"-shaped vertical plate of the slide rail 1. The guide wheels 34 are mounted on the guide wheel seat 33, and a pair of shaft columns 38 are provided at the rear end of the guide wheel seat 33. The shaft columns 38 are inserted into the shaft holes opened in the vertical plate of the collar slider box body 4. Leaf springs 35 are provided above and below the shaft columns 38 between the vertical plate of the collar slider box body 4, and the arched end of the leaf spring 35 is pressed against the guide wheel seat 33.
