Description
Technical field
The present invention relates to vaulting standard, refer more particularly to the lifting servo that is used for the vaulting standard over brace.
Background technology
Vaulting standard is widely used a kind of sports apparatus on the stadium.Vaulting standard commonly used at present, its structure generally includes: base, base is provided with column, be provided with the device of control over brace lifting in the column, this device comprises: be arranged on the adjusting screw mandrel in the column, the regulating handle that is located on the column matches with regulating screw mandrel, offers the lifting chute on the side sidewall of column, slider bar is passed the lifting chute and is connected with regulating wire rod thread, and the over brace that is used to shelve cross bar is fixedly installed on slider bar.During use, the staff will constantly highly adjust the position of cross bar according to athletic high jump, its adjustment process is: the staff shakes regulating handle, driving the adjusting screw mandrel that cooperates with it rotates, the adjusting screw mandrel drives the slider bar of threaded engagement connection with it again and the over brace that is arranged on the slider bar moves up and down along the lifting chute, makes the cross bar that is shelved on the over brace be adjusted to the height that the sportsman selectes.The shortcoming of the lowering or hoisting gear of this structure is: armrest shakes regulating handle and adjusts the cross bar height, because undue force, the factor such as irregular of exerting oneself, its adjustment process is difficult to hold, when the height of adjusting has surpassed setting height, just need toward readjustment, and, being very easy to occur the excessive situation of readjustment again in readjustment, this just needs constantly to revise back and forth.Do like this, not only the accuracy of cross bar position can not get good assurance, and adjustment process is not only consuming time but also require great effort, and has increased staff's live load greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of easy and simple to handle and can guarantee the lifting servo that the cross bar pin-point accuracy is errorless.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the lifting servo of over brace in the vaulting standard, comprise: column, be set with lifter rack in the column, also slide in the column and be provided with sliding support, sliding support is provided with lifting motor, the output shaft of lifting motor is fixedlyed connected with the end of worm screw, the other end of worm screw is movably arranged in the sliding support, also be provided with power transmission shaft on the sliding support, be disposed with travelling gear and worm gear on the power transmission shaft, and worm gear matches with worm screw, travelling gear matches with lifter rack, also offers the lifting chute in a side of column, and sliding support is provided with the lifting column that matches with the lifting chute, lock(ing) bolt passes the lifting chute slider bar and lifting column is fixed together, and over brace is connected with slider bar.
Above-mentioned lifting motor is the stepping direct current generator.
The invention has the beneficial effects as follows: move up and down along lifter rack because the present invention has taked lifting motor to drive travelling gear by a cover worm gear and worm mechanism, thereby the over brace that drives slider bar and be arranged on the slider bar moves up and down, and reaches the purpose of adjusting the cross bar height.Like this, the accuracy of cross bar height has obtained good guarantee; Simultaneously, alleviated staff's live load greatly.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a main TV structure schematic diagram of the present invention;
Fig. 2 is that the A of lifter rack among Fig. 1, travelling gear, power transmission shaft, worm gear and worm screw is to structural representation;
Fig. 3 is a user mode schematic diagram of the present invention;
Among the figure: 1, base, 2, column, 21, the lifting chute, 3, power transmission shaft, 31, travelling gear, 32, worm gear, 4, lifter rack, 5, worm screw, 6, shaft coupling, 7, slider bar, 8, sliding support, 9, lifting column, 10, lifting motor, 11, over brace, 12, lock(ing) bolt, 13, the pad post.
The specific embodiment
As shown in Figure 1, the lifting servo of over brace in the vaulting standard of the present invention, comprise: column 2, in column 2, be set with lifter rack 4, in column 2, also slide and be provided with sliding support 8, sliding support 8 is provided with lifting motor 10, the output shaft of lifting motor 10 is fixedlyed connected with the end of worm screw 5 by shaft coupling 6, the other end of worm screw 5 is movably arranged in the sliding support 8 by bearing, on sliding support 8, also be provided with power transmission shaft 3, be disposed with travelling gear 31 and worm gear 32 on power transmission shaft 3, power transmission shaft 3 is arranged between worm screw 5 and the lifter rack 4, and worm gear 32 matches with worm screw 5, travelling gear 31 matches with lifter rack 4---referring to shown in Figure 2; Side at column 2 also offers lifting chute 21, sliding support 8 is provided with the lifting column 9 that matches with lifting chute 21, offer positioning spiro pit in the lifting column 9, one end of pad post 13 is provided with the screw thread that matches with positioning spiro pit and is arranged in the positioning spiro pit, the other end of pad post 13 stretches out and rises groove chute 21 and offer the locking screw thread hole, lock(ing) bolt 12 passes slider bar 7 and is threaded with the locking screw thread hole, is set with over brace 11 on the slider bar 7.In the present embodiment, what lifting motor 10 was selected for use is dc stepper motor; This lifting motor 10 is controlled by a cover control device.
As shown in Figure 3, be the shape assumption diagram that is provided with the vaulting standard of lifting servo of the present invention, comprising: base 1, column 2, slider bar 7 and over brace 11.During use, the staff at first is placed on a pair of such pole jump on the corresponding position, then athletic commencing height is inputed in the above-mentioned control device, control device is according to the position at the current place of cross bar and the height of setting, draw the rotation step number of lifting motor 10 through computing, control device starts lifting motor 10 runnings, lifting motor 10 drives worm screw 5 by its output shaft and rotates, worm screw 5 drives worm gear 32 runnings that cooperate with it again, and since worm gear 32 and travelling gear 31 be fixedly installed on the same axis, making travelling gear 31 follow worm gear 32 rotates together, and the rotation of travelling gear 31, make travelling gear 31 move up or down along the lifter rack 4 that cooperates with it, travelling gear 31 drives whole sliding support 8 and moves up and down along lifter rack 4, and sliding support 8 drives slider bar 7 again and the over brace 11 that is arranged on the slider bar 7 moves up and down; When lifting motor 10 went to the step number of setting, lifting motor 10 stopped operating.At this moment, because the self-locking action of worm gear 32 and worm screw 5, over brace 11 is just fixed on column 2, and cross bar arrives setting height.
