Description
Technical field
The invention belongs to sports dedicated unit technical field, it is related to one kind and has an effect when can detecte sportsman's pitch-pot game greatly
Small and direction Wheelchair Curling push rod.
Background technique
Wheelchair Curling movement is a young movement, it rises in Europe in late 1990s and passes to Europe rapidly
Continent, due to itself interest and athletics, the favor of numerous sports enthusiasts has been won rapidly in Wheelchair Curling movement.
Wheelchair Curling movement uses identical racing track and identical curling stone stone, Wheelchair Curling fortune with traditional curling
Dynamic certain rules are also the rule with reference to curling, but the two still has obvious difference.Wheelchair Curling
In movement, sportsman must be sitting on wheelchair, carry out pitch-pot game using push rod, in addition, not having during Wheelchair Curling is competed and carried out
Ice link is swept, therefore the control in strength size and direction there are more strict requirements when to sportsman's pitch-pot game.
When pitch-pot game, pitch-pot game sportsman first fixes wheelchair, grasps curling stone push rod body of rod end hand grip, uses push rod cup
Bayonet set entangle curling stone handle, according to be located at base camp side leading player indicate determine pitch-pot game route and determine pitch-pot game institute
Then the strength needed and direction grasp the shoulder elbow wrist joint coordinated movement of various economic factors of the arm of push rod body of rod end hand grip side to mesh
Direction push rod is marked, makes to cover the curling stone on push rod cup and moves a distance by scheduled circuit and accelerated, when using the push rod cup,
There are certain spacing between the sticking point of sportsman and the mass center of curling stone, therefore the thrust of sportsman can not only be such that curling stone obtains
Along the linear velocity of target direction, while curling stone can also be made to obtain a certain size angular speed.Before reaching expected before lag line
It covers curling stone and bayonet after into speed and angular velocity of rotation to be detached from, completes pitch-pot game movement.Wherein the forward speed of curling stone by
The strength size of sportsman determines, the rotation speed of curling stone by sportsman strength and sportsman's sticking point and curling stone center of gravity it
Between distance determine that the distance can be changed by the caging bolt on rotating push rod head.
For common curling stone after releasing, two curling stone team members can be before curling track according to curling stone operation conditions
Brush ice appropriate is carried out, to change the surface topography of ice face in front of curling stone, reduces the coefficient of friction of ice face, and then increase curling stone
Run duration, increase the move distance of curling stone, in addition, experiment show that brush ice appropriate can effectively reduce curling rail
The deflection distance of mark, therefore, it can be seen that brush ice all have to the move distance of curling stone and the motion profile of curling stone it is important
It influences.But Wheelchair Curling does not allow to sweep ice, so Wheelchair Curling sportsman needs to accurately control applied force during pitch-pot game
The size of amount and direction, to reach ideal tactical purpose.
But found according to the investigation to existing curling stone push rod, existing curling stone push rod can only reach the length to push rod
A certain range of adjusting (a kind of Wheelchair Curling push rod as disclosed in application number CN201811174462.X) is carried out, can not effectively be mentioned
High sportsman's pitch-pot game success rate, the strength size and direction that sportsman is applied during pitch-pot game can only be by sportsmen for a long time
Training experience judged, so far, and Wheelchair Curling sportsman can not be pushed away during pot strength size and direction into
Row real-time detection, the success of pitch-pot game with unsuccessfully lack science and effective quantitative analysis, strong influence Wheelchair Curling movement
The raising of member's pitch-pot game success rate.
Summary of the invention
The purpose of the present invention is to provide it is a kind of can real-time detection sportsman push away have an effect during pot size and direction
