Background technology
It is after no play that rugby is striven the limit ball, adopts and knocks down the mode between two row sportsmen to ball, comes rapidly, restarts safely.It is one of rugby four Large Groups technology that rugby is striven limit playing skill art, is to set up a play and effectively obtain the important means of score.The accuracy of delivering is that this technology cooperates key, also is the core of technology and the prerequisite key element of the success or failure that set up a play.The at present international and domestic simulative training platform that does not still have this technology of exploitation; Make the training of this technology can only rely on the exercise that cooperatively interacts of manpower; There is very big defective in a series of requirements of quality, efficient, intensity and the combination cooperation etc. of exercise; Cause this technology often making a fault in play not stable in performance, the intention of strategy, the tactics of match can't be achieved by the target of anticipation with technology.The development that rugby is delivered and to be fixed apparatus can solve the problem of above-mentioned existence, for the stable performance of technology provides safety and ensured that also the expansion performance for this technology provides perfect training tool.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of can substituting to lift team member, outplayer and be the deliver rugby delivery center punch of training of delivery team member.
The purpose of the invention realizes through following technical proposals: rugby delivery center punch is characterized in that: be made up of base, walking mechanism, column, gear elevating mechanism and whirling arm mechanism, described column is made up of four joint columns; Wherein first column is positioned at the bottom, and is connected through flange with base, and the 4th column is positioned at the top; Be provided with whirling arm mechanism above that, described whirling arm mechanism structure is: installation shaft bearing on the 4th column, and rotating shaft is set on the bearing block through bearing; Rotating disc is installed on rotating shaft, on bearing block, is provided with cover plate, be connected with limiting plate at an end of cover plate; Limiting plate is provided with extension spring, and extension spring is connected with an end of rotating disc through hanging the spring bolt, is provided with at the other end of rotating disc and simulates the arm socket; Simulation arm socket is connected with the simulation arm, on first column, is provided with chute and elevating mechanism, and described elevating mechanism structure is: on first column, support plate is installed; On support plate, be provided with bearing block, couple axle and bearing are housed in it, gear is installed on couple axle; Gear is meshed with tooth bar on second column, and tooth bar slides in the chute of first column, and handwheel is installed in the couple axle end; The other end at couple axle is installed ratchet, ratchet and limited block; On first column, be provided with reinforcing ring, the termination of second column, the 3rd column is provided with lock sleeve, and described walking mechanism comprises road wheel and the walking handle that is installed on the base.
The beneficial effect of the invention: use this rugby delivery center punch, can strengthen and improve training targetedly to delivery team member's throwing technique ability.Exercise can 2 people or the exercise of many people subtend, also can 1 many balls of people specific exercises.Can remove the consumption and the fatigue of lifting the team member of muscle power in deliver teaching and the training, prevent that contingency from taking place.Improve the teaching and the training quality of delivering, promote the raising of level of technique.Can be according to the use object in the field research training, the exercise of accurately delivering of adjustment datum target height.Can combine the place, place to carry out single exercise or modeled fit in all directions practises with reference to the hypothesis enemy.

Fig. 1 is the structure chart of rugby delivery locator.
Fig. 2 is the structure chart of whirling arm mechanism among Fig. 1.
Fig. 3 is the structure chart of elevating mechanism among Fig. 1.
The specific embodiment
Rugby delivery center punch is made up of base 8, walking mechanism, column, gear elevating mechanism and whirling arm mechanism, and walking mechanism comprises road wheel 9 and the walking handle 10 that is installed on the base 8.Column is made up of four pipe joint shape columns, and first column 1, second column 2, the 3rd column 3, the 4th column 4 are installed from the bottom to top successively, and first column 1 is positioned at the bottom; And be connected through flange 11 with base 8, on first column 1, be provided with chute 5 and elevating mechanism I, on first column 1, be provided with reinforcing ring 32,33; Elevating mechanism I structure is: be positioned at reinforcing ring 32 upper parts at first column 1 support plate 12 is installed; On support plate 12, be provided with bearing block 13, couple axle 14 is fixed on the bearing block 13, and gear 16 is installed on couple axle 14; Gear 16 is meshed with tooth bar 15 on second column 2; Tooth bar 15 slides in the chute 5 of first column, and handwheel 17 is installed in couple axle 14 ends, at the other end of couple axle 14 ratchet 18, ratchet 19 and limited block 20 is installed.Be provided with between lock sleeve 6, the three columns 3 and the 4th column 4 between second column 2, the 3rd column 3 and be provided with lock sleeve 7.On the 4th column, be provided with the whirling arm mechanism II, whirling arm mechanism II structure is: installation shaft bearing 21 on the 4th column 4, and rotating shaft 22 is contained on the bearing block 21 through bearing 23; Rotating disc 24 is installed on rotating shaft 22; On bearing block 21, be provided with cover plate 25, be connected with limiting plate 26 at an end of cover plate 25, limiting plate 26 is provided with extension spring 27; Extension spring 27 is connected with an end of rotating disc 24 through hanging spring bolt 28, is provided with at the other end of rotating disc 24 and simulates arm socket 29.Simulation arm 30 is inserted in the simulation arm socket 29.
When off working state, the 4th column 4, the 3rd column 3, second column 2 contract in the sleeve of first column 1, are extreme lower position.
During preparation, the 4th column 4 is at first pulled up in the sleeve of the 3rd column 3, and with lock sleeve 7 locking positionings; Again the 3rd column 3 is extracted in the sleeve of second column 2, when being adjusted to the 4th column 4, utilized elevating mechanism rise column 2 and column 3,4 to raise together again, make whirling arm mechanism reach the highest to the extreme higher position.Owing to be provided with tooth bar 15 in second column 2, gear 16 in the elevating mechanism and tooth bar 15 engagements shake handwheel 17 and make tooth bar 15 drive second column, 2 free liftings.The ratchet 19 control gear strokes of the ratchet mechanism through handwheel 17 other ends stop at an arbitrary position.
After adjusting height, center punch is placed on assigned address, the delivery hand begins training; Mark 31 on the simulation arm 30 is the common hand shape of human body; When the rugby of throwing hits the mark 31 on the simulation arm 30, after simulation arm 30 is stressed, rotation under the drive of whirling arm mechanism II; Extension spring 27 and limiting plate 26 through being provided with in the whirling arm mechanism II realize that simulation arm 30 automatically resets, and eliminates swing.
Behind the end-of-job, mention walking handle 10, the pulling of 30 °~45 of center punch inclination just can be walked arbitrarily.
This locator can substitute two and lift team member and the skyborne outplayer of quilt picking-up; And different according to the human body height of men and women adult group, teenager group and juvenile group and brachium; Traffic altitude scope different features; The column height can carry out the setting of many groups, to satisfy concrete specially position team member's demand height of actual team.Produce and to topple over for not making center punch hit the back, the simulation arm has and is hit the back and rotate the self-return function.The delivery team member can hit according to the real space of this team on schedule, confirms aiming delivery exercise, to improve the accuracy rate of batting.
