Abstract
The invention provides a point switch machine. The point switch machine comprises at least one detecting rod, an actuating rod and a planetary gear mechanism, the planetary gear mechanism is arranged above the actuating rod, and space for accommodating the detecting rod is arranged on two sides of the actuating rod and the planetary gear mechanism respectively. According to the point switch machine, positions of detecting rods of a left machine type and a right machine type of the point switch machine are symmetrical along the actuating rod, the detecting rods are merely required to be adjusted from one side to the other side of the actuating rod during reversing, the reversing of the point switch machine is quite convenient by means of the scheme, the total length of the point switch machine is reduced, and adaptability of the point switch machine is improved.
Description
Technical field
The present invention relates to Railway control equipments, be specifically related to a kind of switch machine.
Background technology
Switch machine is the actuating unit of switch control system.For changing locking point tongue or heart rail, represent position and the state of point tongue or heart rail in supervision interlocking area.
Fig. 1 is a kind of organigram of existing switch machine 10.In this switch machine 10, motor 12 drives ball screw framework 14, and then makes throw rod 16 in left and right directions motion (as shown by the directional arrows a in the diagram).Shown in Fig. 1 is the schematic diagram of left installation state.And when right installation, need the throw rod cover cylinder 17 of switch machine, test rod cover cylinder 18 and test rod 19 to commutate.
Fig. 2 is the organigram of another kind of existing switch machine 20.Wherein, motor 22 drives oil pump 24, carrys out sweeping action bar 28 move by oil cylinder group 26 and auxiliary cylinder group 27.Obviously, for the switch machine shown in Fig. 2, conversion installation direction is more difficult.
Summary of the invention
The object of this invention is to provide a kind of new switch machine.
According to technical scheme of the present invention, a kind of switch machine, comprise at least one test rod and a throw rod, this switch machine comprises a sun and planet gear, described sun and planet gear is located at above described throw rod, is respectively equipped with the space for holding described test rod at described throw rod and described sun and planet gear both sides.
Wherein, described sun and planet gear comprises the axle drive shaft of a bull gear, the planetary wheel be engaged with inside this bull gear, one end and the swing arm of this planetary axle pivot joint and the other end pivot joint with swing arm.
Technique effect of the present invention is, the test rod position of switch machine left installation type and right installation type is arranged symmetrically with relative to throw rod, only test rod need be adjusted to opposite side from the side of throw rod when commutating, the program makes the commutation of switch machine more convenient, and reduce the total length of switch machine, improve the comformability of switch machine.

Detailed description of the invention
Below in conjunction with the preferred embodiments of the present invention, present invention is described.Many concrete details have been enumerated in description below.But, it will be appreciated by those skilled in the art that the present invention also can not adopt some or all in these details and realize.In some situations, known technology does not describe to avoid unnecessary obscuring.
Fig. 3 illustrates the organigram of the switch machine according to one embodiment of the invention.The shell 102 of switch machine 100 forms the space being used for holding mechanism.Wherein throw rod 110 is located in this shell 102, such as, can arrange between two parties.
Sun and planet gear 120 is arranged on the top of this throw rod 110, and with this throw rod 110 on same longitudinal plane.Described " longitudinal plane " is perpendicular to the paper direction in Fig. 3.The space 106 and 108 holding test rod 130 is respectively equipped with, as shown in phantom in Figure 3 in the both sides of throw rod 110.In one example in which, described space 106 this throw rod relative to 108 is symmetrical arranged.
Fig. 3 illustrates and be respectively equipped with test rod in described space 106 and 108, but, can understand as those skilled in the art, generally, only need to arrange a test rod, therefore can only wherein a position test rod is set.
Fig. 4 shows the schematic diagram of described sun and planet gear 120.In Fig. 4, sun and planet gear 120 comprises two groups of compound planet gears 140, but also only can comprise a compound planet gear 140.The planetary wheel 142 that compound planet gear 140 comprises a bull gear 141, is engaged with inside this bull gear, the axle of this planetary wheel 142 is planet axis 143, also comprises the axle drive shaft 145 of the swing arm 144 of one end and this planet axis 143 pivot joint and the other end pivot joint with this swing arm 144.In the example shown in fig. 4, two compound planet gears 140 share an axle drive shaft 145.
Axle drive shaft 145 is flexibly connected with this throw rod 110.The outside of described bull gear 141 is also provided with gear ring, and is connected with motor 150.Those skilled in the art can understand, and can be provided with change speed gear box and gear between the external toothing of bull gear 141 and motor 150.
Above in conjunction with detailed description of the invention to invention has been detailed description.But, it will be appreciated by those skilled in the art that also there are some amendment and equivalent way within the scope of the invention.Therefore, claim of the present invention should be interpreted as comprising all such amendments and equivalent way.
