Description

Automatic conveying system for track and field remote-throwing apparatus

Technical Field

The utility model belongs to the technical field of the sports apparatus transports, concretely relates to automatic conveying system of apparatus is thrown to track and field distance.

Background

At present, the variety and the quantity of the game apparatus in the sports events are various, wherein the track and field long throw type project game comprises various apparatuses such as javelins, shot balls, hammer balls, discus and the like. The transportation problem of the track and field remote throwing apparatus in the competition process is a key problem which restricts the smooth competition. The track and field rules stipulate that for the apparatus of throwing (throwing) project competition, the apparatus should be transported back to the placing area of the throwing apparatus, and the throwing is not allowed. According to the characteristics of track and field events in track and field competitions, in many sports competitions at all levels, the field instruments for throwing (throwing) events are carried manually and returned to the placing area of the throwing ring instruments, and the process conflicts with the competition of athletes, so that not only is safety accidents easy to happen, but also the workload of field referees is increased. In the prior art, the remote control instrument recovery vehicle is used for recovering instruments, but an off-site operator is required to operate the recovery vehicle, so that the efficiency is low, and certain potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatic conveying system of apparatus is thrown far away in track and field, can effectively overcome the shortcoming that prior art exists.

The utility model discloses a realize like this, as shown in fig. 1, characterized by set up the apparatus of installing ultrasonic emitter 201 and place district 2 in the fixed position of playground 4, coach hand-carries wearable locator 3 of installing human ultrasonic emitter 301, and apparatus transfer cart 1 transports track and field distance throwing apparatus on playground 4. As shown in fig. 2, the instrument transport cart 1 is characterized in that two groups of infrared obstacle avoidance sensors 102 are mounted at the front end of a four-wheel cart body 101; a javelin setting seat 103 for fixing a javelin 104, a square hole 101-1 for placing a discus 105 and a circular hole 101-2 for placing a hammer 106 are arranged in the middle; a singlechip control system 107 and an ultrasonic receiving module 108 are fixedly arranged at the rear end; the javelin placement seat 103 is shown in fig. 3 and 4, a rubber javelin piston support frame 103-1 is sleeved in a javelin fixing seat 103-2 cylinder and is abutted against the upper end face of a spring 103-3, and a pressure sensor 103-4 arranged at the bottom in the javelin fixing seat 103-2 cylinder is abutted against the lower end face of the spring 103-3.

The utility model discloses advantage and positive effect are this system simple structure, safe and reliable. The system can be used for rapidly and safely transporting the instruments for the match in the match process, ensures the high efficiency and smooth running of track and field type matches, reduces the number of on-site service personnel for the match and referees who run and recover the instruments in the match, and increases the match appreciation degree.

Description of the drawings:

FIG. 1 is a schematic view of the system of the present invention;

fig. 2 is a schematic structural view of the instrument transportation cart 1;

FIG. 3 is a schematic sectional view taken along line A-A of FIG. 2;

FIG. 4 is an enlarged view of a portion B of FIG. 3;

fig. 5 is a schematic structural view of the four-wheel vehicle body 101.

In the figure: the device comprises a device conveying vehicle 1, a device placing area 2, a wearable positioner 3, a playground 4, a four-wheel vehicle body 101, a square hole 101-1, a circular hole 101-2, an infrared obstacle avoidance sensor 102, a javelin placing seat 103, a piston support frame 103-1, a javelin fixing seat 103-2, a spring 103-3, a pressure sensor 103-4, a javelin 104, a discus 105, a hammer 106, a hammer 107, a singlechip control system 108, an ultrasonic receiving module 109, a battery 201, an ultrasonic transmitter 301, and a human ultrasonic transmitter.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, a field referee wears a wearable positioner 3 on a track and field type competition playground 4, an ultrasonic transmitter 201 is attached to an instrument placement area 2, and an instrument transport vehicle 1 transports a competition instrument at the center of the playground. When the athlete throws the javelin 104, the discus 105, and the hammer 106 to the outside referee to return them to the equipment placing area 2, the ultrasonic receiving module 108 mounted on the equipment cart 1 is automatically positioned to the wearable locator 3 on the outside referee. The transport cart automatically plans the shortest path outside the competition field area line, runs to the side of a referee in the field, the referee in the field places a javelin 104, a discus 105 and a hammer 106 on a javelin placing seat 103, a square hole 101-1 and a circular hole 101-2 respectively, and after the placement is finished, the transport cart automatically positions an ultrasonic transmitter 201 to transport the competition instruments back to an instrument placing area 2. Two groups of infrared obstacle avoidance sensors 102 arranged at the front end of the four-wheel vehicle body 101 in the running process of the instrument transfer cart 1 are used for safely avoiding obstacles for other people and objects.
