[0002] Plastic running tracks have many advantages, including high strength and good elasticity, wear resistance and low temperature resistance, and the hardness can be adjusted according to needs. Construction is convenient and can be paved directly on cement or asphalt surfaces, with low maintenance costs, and lane lines and markings remain for a long time. It has high friction, anti-slip particles, good flatness, and strong pressure resistance, which helps athletes to display their speed and skills. Its strength, hardness, elasticity and other indicators as well as thickness and style can be adjusted widely to adapt to different competition and training requirements. It has good weather resistance and is not affected by temperature and humidity. It drains quickly and can be put into use quickly after rain. It can be called an all-weather sports venue, fully guaranteeing the athletes' sports experience. Plastic running tracks also need to be regularly tested for their elasticity to ensure their ability to protect athletes.

[0003] Existing detection devices usually use hammering to detect the elasticity of plastic tracks. During the hammering process, corresponding sensors are used to detect the deformation of the track. However, the detection process can only reflect the elasticity of a local area of ​​the track, thereby reducing the detection effect.

[0004] Therefore, a mobile elasticity detection device for a gymnasium plastic track is proposed to solve the above problems. Summary of the Invention

[0005] In response to the above problems, the present invention provides a mobile elasticity detection device for a gymnasium plastic track, comprising a support mechanism, a running mechanism, and a counterweight mechanism. The support mechanism is used to provide support for the running mechanism, and the counterweight mechanism is installed on the side of the running mechanism to increase the weight of the running mechanism. The running mechanism includes a driving member, a transmission member, and a driven member. The driving member drives the driven member to move through the transmission member. The driven member is equipped with an artificial foot. The bottom of the artificial foot is fixedly equipped with a detector for elasticity detection of the plastic track. The supporting mechanism includes a bracket for mounting the driving member and a rubber wheel mounted on the bottom of the bracket.

[0006] Furthermore, the driving member includes a reducer and a motor that drives the reducer to rotate, the output end of the motor is fixedly connected to the reducer, and the reducer and the motor can be detachably mounted on the bracket.

[0007] Furthermore, the transmission member includes an eccentric wheel key-connected to the output end of the reducer, and a first connecting rod and a second connecting rod are rotatably mounted on the convex shaft of the eccentric wheel, and the first connecting rod and the second connecting rod are transmission-connected to the driven member.

[0008] Furthermore, the follower includes a movable block rotatably mounted on the reducer housing, a third connecting rod, and a fourth connecting rod rotatably mounted on the side of the movable block. The third connecting rod is rotatably connected to the first connecting rod, and one end of the third connecting rod rotates coaxially with the movable block. The side of the movable block away from the reducer housing is rotatably connected to the end of the second connecting rod away from the eccentric wheel. The ends of the third and fourth connecting rods away from the movable block are rotatably connected to the fifth connecting rod. The side of the third connecting rod is rotatably connected to the sixth connecting rod. The ends of the fifth and sixth connecting rods are rotatably connected to the artificial foot, and the counterweight is fixedly mounted on the side of the fifth connecting rod.

[0009] Furthermore, the counterweight member includes a placement shell for placing the counterweight block and an airbag mechanism for providing cushioning for the counterweight block. A cover plate is clamped and fixed to the upper part of the placement shell, and the airbag mechanism is installed at the bottom of the cover plate. A first rubber pad for providing cushioning for the counterweight block is fixedly installed in the placement shell, and the placement shell is fixedly installed on the side of the fifth connecting rod.

[0010] Furthermore, the airbag mechanism includes a first airbag, a second airbag and an air guide tube, the first airbag is connected to the second airbag through the air guide tube, the first airbag is fixedly installed on the bottom of the cover plate, and the second airbag is fixedly installed in the artificial foot.

[0011] Furthermore, a telescopic member for providing cushioning is fixedly mounted on the artificial foot, and the telescopic member can be communicated with the second airbag.

[0012] Furthermore, the telescopic part includes a piston, a piston tube and a connecting rod. The piston is slidably installed in the piston tube. The connecting rod is fixedly connected to the piston. The upper end of the connecting rod is fixedly connected to a guide rod for guiding. A guide groove that slides with the guide rod is opened in the gap of the simulated foot, and the piston tube is connected to the second airbag.

[0013] Furthermore, a spring is fixedly installed in the piston tube, and one end of the spring is fixedly connected to an end of the piston away from the connecting rod.

[0014] Furthermore, a second rubber pad is provided at the bottom of the artificial foot.

[0015] The beneficial effects of the present invention are: 1. Through the use of the running mechanism, when the motor is working, it drives the gears in the reducer to rotate, thereby driving the eccentric wheel to rotate. When the eccentric wheel rotates, it drives the first connecting rod and the second connecting rod to swing. The first connecting rod drives the third connecting rod to swing, and the second connecting rod drives the movable block to rotate. Therefore, the movable block drives the fourth connecting rod to swing, and cooperates with the third connecting rod to drive the fifth connecting rod to swing. At the same time, the third connecting rod drives the sixth connecting rod to swing, so that the simulated foot on one side performs a cyclic action of lifting and lowering, and the simulated foot on the other side performs a cyclic action of lowering and lifting, forming a running action, so that the detector can perform elasticity inspection on the plastic track according to the simulated running action. Compared with hammer detection, testing the plastic track during the running movement of the running mechanism can effectively improve the elasticity detection range and obtain more sufficient data.

[0016] 2. Through the use of counterweights, the weight of the follower can be adjusted when conducting elasticity testing on the plastic track. By adding counterweights, the elasticity test of the plastic track driven by the simulated foot can be simulated under different weights when the running mechanism is running. The elasticity data under various conditions can be obtained. Compared with hammer testing, the detector can obtain more accurate test results based on the elastic data generated when the simulated foot contacts the plastic track when the running mechanism is running under different counterweights.

[0017] 3. Through the use of the airbag mechanism, when the running mechanism is running, the simulated foot contacts the plastic track and generates an impact, which will also generate an impact on the counterweight placed in the placement shell. When the simulated foot is impacted, the second rubber pad and the second airbag cushion the impact and reduce the impact intensity. At the same time, if the second airbag is under greater pressure, the gas in the second airbag can be injected into the first airbag through the air duct, so that the first airbag is further close to the counterweight and cooperates with the first rubber pad to cushion the counterweight. After the impact is over, the gas introduced into the first airbag by the air duct is discharged into the second airbag to ensure the cushioning effect of the second airbag, which can effectively reduce the impact on the running mechanism during running.

[0018] 4. Through the use of telescopic parts, when the artificial foot contacts the plastic track, if the second airbag is compressed by impact, the gas in the second airbag can be passed into the piston tube, and the airbag can be depressurized to protect the second airbag. At the same time, when impacted, the guide rod moves along the guide groove to guide the impact, and the piston slides frictionally in the piston tube to further cushion the impact, effectively reducing the impact on the device components when the artificial foot contacts the plastic track, and can effectively provide cushioning protection for the structure of the device.

[0019] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The embodiment of the present invention provides a mobile elasticity detection device for a gymnasium plastic track, for example, Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, it includes a support mechanism 1, a running mechanism 2 and a counterweight mechanism 3. The support mechanism 1 is used to provide support for the running mechanism. The counterweight mechanism 3 is installed on the side of the running mechanism 2 and is used to increase the weight of the running mechanism 2. Specifically, the support mechanism 1 includes a bracket 6 for mounting the driving member, and a rubber wheel 7 mounted on the bottom of the bracket 6 .

[0033] It should be noted that there are four rubber wheels 7, and two of them are configured as universal wheels to facilitate the movement of the bracket 6; The bracket 6 can be equipped with a power supply for power supply and a display for displaying the detection data of the detector in real time, so that the runway area of ​​the data can be marked with the staff.

[0034] Specifically, the running mechanism 2 includes a driving member, a transmission member, and a driven member. The driving member drives the driven member to move through the transmission member. The driven member is mounted with an artificial foot 4. A second rubber pad 31 is provided at the bottom of the artificial foot 4. A detector 5 for elasticity detection of the plastic track is fixedly mounted at the bottom of the artificial foot 4. For example, Figure 1 、 Figure 3 and Figure 6 As shown, the driving member includes a reducer 8 and a motor 9 that drives the reducer 8 to rotate. The output end of the motor 9 is fixedly connected to the reducer 8. The reducer 8 and the motor 9 can be detachably mounted on the bracket 6.

[0035] It should be noted that the motor 9 is configured as a servo motor, which can adjust the output speed of the reducer, adjust the running speed of the running mechanism, and perform elasticity testing on the plastic track at simulated different speeds.

[0036] Specifically, the transmission member includes an eccentric wheel 10 key-connected to the output end of the reducer 8, and a first connecting rod 11 and a second connecting rod 12 are rotatably mounted on the convex shaft of the eccentric wheel 10. The first connecting rod 11 and the second connecting rod 12 are transmission-connected to the driven member.

[0037] It should be noted that two eccentric wheels 10 are provided, and two transmission members and two driven members are provided.

[0038] Specifically, the follower includes a movable block 13 rotatably mounted on the housing of the reducer 8, a third connecting rod 14, and a fourth connecting rod 15 rotatably mounted on the side of the movable block 13. The third connecting rod 14 is rotatably connected to the first connecting rod 11, and one end of the third connecting rod 14 rotates coaxially with the movable block 13. The side of the movable block 13 away from the housing of the reducer 8 is rotatably connected to the end of the second connecting rod 12 away from the eccentric wheel 10. The third connecting rod 14 and the fourth connecting rod 15 are rotatably connected to the fifth connecting rod 16 at one end away from the movable block 13. The side of the third connecting rod 14 is rotatably connected to the sixth connecting rod 17. The ends of the fifth connecting rod 16 and the sixth connecting rod 17 are rotatably connected to the artificial foot 4, and the counterweight is fixedly mounted on the side of the fifth connecting rod 16.

[0039] It should be noted that the artificial foot 4 is rotatably connected to the fifth connecting rod 16 and the sixth connecting rod 17 by a pin, so that after the inspection is completed, the staff can push the bracket 6 to move the device out of the plastic track.

[0040] Through the use of the running mechanism 2, when the motor 9 is working, it drives the gears in the reducer 8 to rotate, thereby driving the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, it drives the first connecting rod 11 and the second connecting rod 12 to swing. The first connecting rod 11 pushes the third connecting rod 14 to swing, and the second connecting rod 12 pushes the movable block 13 to rotate. Therefore, the movable block 13 drives the fourth connecting rod 15 to swing, and cooperates with the third connecting rod 14 to drive the fifth connecting rod 16 to swing. At the same time, the third connecting rod 14 drives the sixth connecting rod 17 to swing, so that the simulated foot 4 on one side performs a cyclic action of lifting and lowering, and the simulated foot on the other side performs a cyclic action of lowering and lifting, forming a running action, so that the detector 5 can perform elasticity inspection on the plastic track according to the simulated running action. Compared with hammer detection, testing the plastic track during the running movement of the running mechanism can effectively improve the elasticity detection range and obtain more sufficient data.

[0041] For example, Figure 4 and Figure 9 As shown, the counterweight member includes a placement shell 18 for placing the counterweight block and an airbag mechanism for providing cushioning for the counterweight block. A cover plate 19 is clamped and fixed to the upper part of the placement shell 18, and the airbag mechanism is installed at the bottom of the cover plate 19. A first rubber pad 20 for providing cushioning for the counterweight block is fixedly installed in the placement shell 18, and the placement shell 18 is fixedly installed on the side of the fifth connecting rod 16.

[0042] By using counterweights, the weight of the follower can be adjusted when performing elasticity testing on the plastic track. By adding counterweights, the running mechanism can be simulated under different weights. When running, the simulation foot 4 drives the detector 5 to perform elasticity testing on the plastic track, and elasticity data under various conditions can be obtained. Compared with hammer testing, the detector can obtain more accurate test results based on the elasticity data generated when the simulation foot 4 contacts the plastic track when the running mechanism 2 is running under different counterweights.

[0043] For example, Figure 4 and Figure 9 As shown, the airbag mechanism includes a first airbag 21, a second airbag 22 and an air guide tube 23. The first airbag 21 is connected to the second airbag 22 through the air guide tube 23. The first airbag 21 is fixedly installed at the bottom of the cover plate 19, and the second airbag 22 is fixedly installed in the artificial foot 4.

[0044] It should be noted that after the cover plate 19 is installed, one side of the first airbag 21 is in close contact with the counterweight block in the placement shell 18 .

[0045] Through the use of the airbag mechanism, when the running mechanism is running, the simulated foot 4 contacts the plastic track and generates an impact, which will also generate an impact on the counterweight placed in the placement shell 18. When the simulated foot 4 is impacted, the second rubber pad 31 and the second airbag 22 cushion the impact and reduce the impact intensity. At the same time, if the second airbag 22 is under greater pressure, the gas in the second airbag 22 can be injected into the first airbag 21 through the air duct, so that the first airbag 21 is further close to the counterweight, and cooperates with the first rubber pad 20 to cushion the counterweight. After the impact is over, the gas introduced into the first airbag 21 by the air duct 23 is discharged into the second airbag 22 to ensure the cushioning effect of the second airbag 22, which can effectively reduce the impact on the running mechanism during the running movement.

[0046] For example, Figure 5 and Figure 8 As shown, a telescopic member 24 for providing cushioning is fixedly mounted on the artificial foot 4 , and the telescopic member 24 can be communicated with the second airbag 22 .

[0047] Specifically, the telescopic part 24 includes a piston 25, a piston tube 26 and a connecting rod 27. The piston 25 is slidably installed in the piston tube 26. The connecting rod 27 is fixedly connected to the piston 25. The upper end of the connecting rod 27 is fixedly connected to a guide rod 28 for guiding. A guide groove 29 that slides with the guide rod 28 is opened in the gap of the artificial foot 4. The piston tube 26 is connected to the second airbag 22.

[0048] Specifically, a spring 30 is fixedly installed in the piston tube 26 , and one end of the spring 30 is fixedly connected to the end of the piston 25 away from the connecting rod 27 . The spring 30 is used to assist the piston 25 in resetting.

[0049] By using the telescopic part 24, when the artificial foot 4 contacts the plastic track, if the second airbag 22 is impacted and compressed, the gas in the second airbag 22 can be passed into the piston tube 26, and the airbag can be depressurized to protect the second airbag. At the same time, when impacted, the guide rod 28 moves along the guide groove 29 to guide the impact, and the piston can slide frictionally in the piston tube to further cushion the impact, effectively reducing the impact on the device components when the artificial foot 5 contacts the plastic track, and can effectively provide cushioning protection for the structure of the device.

[0050] The above embodiment has the following beneficial effects: 1. Through the use of the running mechanism 2, when the motor 9 is working, it drives the gears in the reducer 8 to rotate, thereby driving the eccentric wheel 10 to rotate. When the eccentric wheel 10 rotates, it drives the first connecting rod 11 and the second connecting rod 12 to swing. The first connecting rod 11 pushes the third connecting rod 14 to swing, and the second connecting rod 12 pushes the movable block 13 to rotate. Therefore, the movable block 13 drives the fourth connecting rod 15 to swing, and cooperates with the third connecting rod 14 to drive the fifth connecting rod 16 to swing. At the same time, the third connecting rod 14 drives the sixth connecting rod 17 to swing, so that the simulated foot 4 on one side performs a cyclic action of lifting and lowering, and the simulated foot on the other side performs a cyclic action of lowering and lifting, forming a running action, so that the detector 5 can perform elasticity inspection on the plastic track according to the simulated running action. Compared with hammer detection, testing the plastic track during the running movement of the running mechanism 2 can effectively improve the elasticity detection range and obtain more sufficient data.

[0051] 2. By using counterweights, the weight of the follower can be adjusted when performing elasticity testing on the plastic track. By adding counterweights, the running mechanism 2 can be simulated under different weights. When running, the simulation foot 4 drives the detector 5 to perform elasticity testing on the plastic track, and elasticity data under various conditions can be obtained. Compared with hammer testing, the detector 5 can obtain more accurate test results based on the elasticity data generated when the simulation foot 4 contacts the plastic track when the running mechanism 2 is running under different counterweights.

[0052] 3. Through the use of the airbag mechanism, when the running mechanism is running, the simulated foot 4 contacts the plastic track and generates an impact, which will also generate an impact on the counterweight placed in the placement shell 18. When the simulated foot 4 is impacted, the second rubber pad 31 and the second airbag 22 cushion the impact and reduce the impact intensity. At the same time, if the second airbag 22 is under greater pressure, the gas in the second airbag 22 can be injected into the first airbag 21 through the air duct, so that the first airbag 21 is further close to the counterweight and cooperates with the first rubber pad 20 to cushion the counterweight. After the impact is over, the gas introduced into the first airbag 21 by the air duct 23 is discharged into the second airbag 22 to ensure the cushioning effect of the second airbag 22, which can effectively reduce the impact on the running mechanism during running.

[0053] 4. Through the use of the telescopic member 24, when the artificial foot 4 contacts the plastic track, if the second airbag 22 is impacted and compressed, the gas in the second airbag 22 can be passed into the piston tube 26, and the airbag can be depressurized to protect the second airbag. At the same time, when impacted, the guide rod 28 moves along the guide groove 29 to guide the impact, and the piston slides frictionally in the piston tube to further cushion the impact, effectively reducing the impact on the device components when the artificial foot 5 contacts the plastic track, and can effectively provide cushioning protection for the structure of the device.
