Abstract
The utility model discloses a positioning device in a propelling mechanism of a direct current circuit breaker truck. The positioning device comprises a lead screw, a rocking handle, a positioning pull rod and a propelling nut, and the positioning device further comprises a positioning block and a positioning pin, wherein the positioning block is mounted on a mounting plate above a truck frame through a screw, and the positioning pin is mounted on the lead screw. The positioning device disclosed by the utility model has the advantages of simple structure, convenience in use, low cost, convenience in processing and capability of greatly improving precision positioning of the truck.
Description
Technical field
The utility model relates to a kind of positioner, the positioner in particularly a kind of dc circuit breaker handcart advancing mechanism.
Background technology
Propulsive mechanism is the vitals on the dc switch equipment dc circuit breaker handcart; Can push circuit breaker cart to service position from test position through propulsive mechanism; Otherwise also can handcart be returned to test position from the service position; Positioner plays an important role to propulsive mechanism, and propulsive mechanism reasonable in design is more and more important to manufacturer.
The positioning tie bar of existing positioner is to be fixed on the propulsive mechanism; In the process that handcart is advancing; Control the stroke of handcart through the length of positioning tie bar,, form cumulative errors because propulsive mechanism is to be assembled by multiple part; Regular meeting crank handle occurs and still can rotate the 0-30 degree in the time of like this after handcart puts in place, and the stroke that cooperates of the dynamic/static contact of handcart also can be followed and form error together so simultaneously.
The utility model content
The technical problem that the utility model will solve provides positioner in a kind of dc circuit breaker handcart advancing mechanism and solves existing positioner and locate inaccurate problem.
For achieving the above object, the technical scheme of the utility model is following:
Positioner in a kind of dc circuit breaker handcart advancing mechanism; Comprise screw mandrel, crank handle, positioning tie bar and pushnut; Said positioner also comprises locating piece and alignment pin, and said locating piece is installed on the mounting panel of vehicle frame top through screw, and said alignment pin is installed on the screw mandrel.
Through technique scheme, the beneficial effect of the utility model is:
The utility model is through coming rival car precisely to locate increasing alignment pin on the screw mandrel and on the handcart upper cover plate, increase locating piece; According to new design former should handcart when the test position alignment pin on the screw mandrel decide anterior protruding 0 degree that partly is limited in initial rotation of piece on by handcart; Alignment pin when handcart advances the back to arrive the service position on the screw mandrel; By protruding 0 degree that finishes to rotate that partly is limited in the rear portion of locating piece on the handcart, the rotation error of handcart screw mandrel after putting in place just is controlled in the scope of 0～1 degree like this.
Convenient when the utility model alignment pin and locating piece installation and maintenance or dismounting; Do not processed or the influence of assembly error, can make the circuit breaker cart mechanism stable, dynamic/static contact remains the excellent contact state; Whole feeding circuit resistance stabilization, advantage of low manufacturing cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
The numeral corresponding component title represented among the figure with letter:
1, locating piece 2, alignment pin 3, screw mandrel 4, crank handle 5, positioning tie bar 6, pushnut
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1; Positioner in a kind of dc circuit breaker handcart advancing mechanism of the utility model comprises screw mandrel 3, crank handle 4, positioning tie bar 5 and pushnut 6; Said positioner also comprises locating piece 1 and alignment pin 2; Said locating piece 1 is installed on the mounting panel (not marking among the figure) of vehicle frame top through screw (not marking among the figure), and said alignment pin 2 is installed on the screw mandrel 3.
The utility model locating piece 1 it adopt band steel to process, and 2 of alignment pins adopt square steel to process; The mechanical strength of material therefor itself limits necessary mechanical strength mutually when being much higher than two part time jobs.
When handcart needs to shake earlier crank handle 4 clockwise when test position moves to the service position, operate screw mandrel 3 through crank handle 4 and rotate, when screw mandrel 3 rotates, pushnut 6 will promote whole handcart by test position to the service position.Otherwise when rotating counterclockwise crank handle 4, pushnut 6 returns to test position with whole handcart by the service position; When handcart at two location swaps the time length through positioning tie bar 5 and locating piece 1, alignment pin 2 limit this dual mode mutually and come rival car to position.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
Claims (1)
1. the positioner in the dc circuit breaker handcart advancing mechanism; Comprise screw mandrel, crank handle, positioning tie bar and pushnut; It is characterized in that; Said positioner also comprises locating piece and alignment pin, and said locating piece is installed on the mounting panel of vehicle frame top through screw, and said alignment pin is installed on the screw mandrel.
