Abstract
The utility model discloses an equatorial instrument. The equatorial instrument comprises a support base, a U-shaped right ascension axis base, a right ascension axis, a declination axis base, a declination axis, a balance bar connecting block, a balance bar and a balance weight. The U-shaped right ascension axis base is fixed on an arc support surface of the support base. The declination axis base is fixed with the middle part of the right ascension axis and is vertical to the right ascension axis. The high end of the right ascension axis is provided with the balance bar connecting block. The balance bar is disposed below the connecting block and opposite to the direction of the declination axis. The balance bar is provided with the balance weight that can adjust positions. The declination axis, the right ascension axis and the balance bar form a Z shape. The center of gravity of the system at any latitude is near the center of the arc surface of the support base, so that the equatorial instrument remains the balanced state.
Description
Affiliated technical field: the present invention relates to a kind of astronomical telescope pallet.Especially equatorial telescope.
Background technology: moral formula equatorial telescope is a kind of astronomical instrument the most frequently used in astronomical sight and photography.Moral formula equatorial telescope is open, is applicable to refraction, reflection, the various astronomical telescopes such as catadioptric.Right ascension axle and the declination axis of moral formula equatorial telescope are orthogonal, telescope and balance counter weight are placed in respectively the two ends of declination axis, declination axis becomes T font with right ascension axle, right ascension axle bed is fixed on the strong point of base for supporting, and celestial pole (imaginary axis that is parallel to earth rotation) is pointed in one end of right ascension axle.Declination axle bed is fixed on one end that right ascension axle points to celestial pole, and one end of declination axis is astronomical telescope fixedly, and the other end is equipped with counterweight hammer.CELESTRON company of picture U.S. MEADE company, VIXEN company of Japanese TAKAHASHI company, the serial moral formula equatorial telescope that Nanjing iOptron company now produces is all this type.The feature of moral formula equatorial telescope is to hammer telescope and counterweight into shape be all in right ascension axle one end, therefore the center of gravity of moral formula equatorial telescope system instrument high-end under the line, strong point distance with base for supporting, the arm of force is long, stiff stability is poor, in order to strengthen rigidity and stability, can only increase volume and weight.And in the middle low latitudes nonequilibrium condition in leaning forward always, adjust pole axis very inconvenient (will use very large moment), latitude is more low more difficult, has increased use difficulty, has reduced the precision of system.
Summary of the invention: the object of the invention is to overcome the defect that above-mentioned prior art exists, a kind of equatorial telescope is provided, this equatorial telescope can make the center of gravity of whole telescopic system be in base for supporting center near, U-shaped right ascension axle bed is connected by the strong point and changes supporting surface into base.
Equatorial telescope of the present invention comprises base for supporting, right ascension axle and U-shaped right ascension axle bed, declination axis and declination axle bed, balance stem contiguous block, balance stem and balance counter weight.Base for supporting is fixed on the pedestal or tripod perpendicular to ground, and U-shaped right ascension axle bed is fixed on the supporting surface of base for supporting and can regulates the elevation angle according to Position Latitude.Declination axle bed be fixed on the right ascension axle in the middle of U-shaped right ascension axle bed and with the vertical .T of one-tenth shape of right ascension axle, dovetail mount is housed on the top of declination axis can be connected with telescopical coattail board.At the high-end balance stem contiguous block that is fixedly equipped with of right ascension axle, the reverse direction of contiguous block below declination axis is equipped with balance stem, and the angle of balance stem and right ascension axle can regulate at 90 degree between 110 degree, and the counterweight hammer of adjustable position is housed on balance stem.Declination axis becomes zigzag with right ascension axle with balance stem.
Equatorial telescope of the present invention is compared with moral formula equatorial telescope the balance stem of the telescopical declination axis of carrying and carrying counterweight hammer is placed in respectively to the middle-end of right ascension axle and high-end, the load center of gravity of equatorial telescope moves on near the central point of base for supporting circle arc support face from right ascension axle high-end, thereby make telescopic system in all use latitude scope all in equilibrium state, improved force-bearing situation, alleviate equatorial telescope weight, increased system mechanics intensity, and owing to making to regulate pole axis to become light in equilibrium state.Separately due to balance stem and right ascension axle clamp angle adjustable, therefore even if can not interfere with tripod at low latitude region balance counter weight yet.
Accompanying drawing explanation: equatorial telescope of the present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is moral formula equatorial telescope basic structure and force diagram;
Fig. 2 is equatorial telescope basic structure of the present invention and force diagram;
Fig. 3 is the cut-open view of equatorial telescope embodiment of the present invention;
Embodiment: Figure 1 shows that the moral formula equatorial telescope basic structure that background technology is mentioned above.The center of gravity that we can see telescope and balance counter weight in Fig. 1 is at G place, with strong point O place's apart from each other and outside base, when base can lean forward fixedly time.Owing to regulating the arm of force at the elevation angle to arrive the distance of the strong point much smaller than the center of gravity of telescopic system, therefore regulate difficulty.System rigidity is poor.
Shown in Fig. 2, be the basic structure of equatorial telescope of the present invention.In Fig. 2 we can see the center of gravity G of load and circle arc support Mian center more approaching, and in using latitude gamut all in base for supporting, whole system is in equilibrium state.
Fig. 3 shows the embodiment of equatorial telescope of the present invention.U-shaped right ascension seat 1 is fixed on the circle arc support face of base for supporting 2, regulates worm screw 14 can regulate the elevation angle of U-shaped right ascension seat 1.Right ascension axle 4 is fixed in U-shaped right ascension seat 1 by bearing 9 and bearing 10.Right ascension axle 4 high-end, fixing balance stem contiguous block 6 is housed, balance stem 7 is fixed on balance stem contiguous block 6, and counterweight hammer 8 is enclosed within can slidable adjustment balance on balance stem 7.Middle-end at right ascension axle 4 is fixed with declination seat 5, and declination seat 5 can be rotated with right ascension axle 4.Declination axis 3 is fixed in declination seat 5 by bearing 11 and bearing 12.Most significant end at declination axis 3 is equipped with fixing dovetail mount 13, to be connected with telescope.By regulating the relative position of telescopical front and back position and balance bob 11 can make the center of gravity of system be adjusted on the strong point of base for supporting 2.
