It should be noted that these embodiments are provided so that this disclosure can be more completely understood and fully conveyed to those skilled in the art, and the present disclosure may be implemented in various forms without being limited to the embodiments set forth herein.
Example 1
As shown in fig. 1-4, an auxiliary device is used in installation of three-phase linkage circuit breaker spring operating mechanism, includes chassis 2, be provided with vertical support 3 on the chassis 2, be provided with vertical drive lead screw 5 on the support 3, be provided with the lead screw seat 51 that can remove on the drive lead screw 5, lead screw seat 51 fixedly connected with lifter plate 6 adopts the lead screw drive mechanism commonly used among the prior art to realize the transmission, and realize the lift of lifter plate 6, provide raising and lowering functions.
Further, the support 3 is symmetrically provided with vertical limiting guide rods 4, the limiting guide rods 4 are arranged on two sides of the lifting plate 6 and penetrate through the lifting plate 6, the lifting plate 6 can move on the limiting guide rods 4, and one end, far away from the bottom frame 2, of the driving screw rod 5 is connected with a driving device. The lifting plate 6 is easy to rotate only by connecting the driving screw 5 with the screw seat 51, so that a corresponding limiting device is required to be arranged to realize the lifting motion of the lifting plate 6 in the vertical direction, and structurally, the limiting guide rods 4 are arranged on two sides of the driving screw 5 and are symmetrically arranged to ensure that the lifting plate 6 is vertically arranged and cannot rotate, and the structural stability is good, the driving screw 5 is required to be connected with a driving device, so that the driving device (generally a driving motor) is required to be connected to the driving screw 5, and the direct connection with a driving shaft is the most appropriate and convenient way, so that the motor mounting table 10 can be arranged above the driving screw 5, the driving motor is arranged on the motor mounting table 10 to drive the driving screw 5 to rotate, and the structure is more convenient to mount and maintain and does not occupy the lower space, the lifter plate 6 can be lowered to a lower position.
After the lifting plate 6 realizes the lifting function, a rotating mechanism matched with the lifting plate needs to be arranged, and the structure is as follows:
a rotating platform 7 is arranged on the surface of the lifting plate 6 departing from the bracket 3, the rotating platform 7 is connected with an installation plate 8, the mounting plate 8 can rotate relative to the lifting plate 6, and the rotating table 7 can adopt a structure commonly used in the prior art, so that the detailed description is omitted, but the specific mounting position is, a driving part mounting part 61 is arranged below the lifting plate 6 and is used for mounting a driving device, the driving device needs to be connected with and drives the rotation driving rod 71 to rotate, then the rotation driving rod 71 drives the driving part 72 to rotate, thereby driving the turntable 73 to rotate, then the turntable 73 drives the mounting plate 8 to rotate, here, a worm and gear structure can be selected, that is, the driving member 72 is a worm, the turntable 73 is a worm wheel, the worm rotates to drive the worm wheel to rotate to realize the function, the realization structure is convenient to find, the rotating effect is good, and other corresponding similar structures are also possible.
Then be the selection to mounting panel 8 later, the mode that mounting panel 8 directly links three-phase linkage circuit breaker spring operating mechanism can be more troublesome, because three-phase linkage circuit breaker spring operating mechanism model is different and the structure is not the plane, consequently chooses for use the surface that mounting panel 8 deviates from lifter plate 6 is provided with mechanism fixed plate 9 mode more suitable, corresponding mechanism fixed plate 9 is used for fixed three-phase linkage circuit breaker spring operating mechanism, can be earlier with three-phase linkage circuit breaker spring operating mechanism with mechanism fixed plate 9 fixed back, again with the fixed mode of mounting panel 8 fixed to need not consider three-phase linkage circuit breaker spring operating mechanism's model, as long as guarantee that mechanism fixed plate 9 can be connected with mounting panel 8 can.
Because three-phase linkage circuit breaker spring operating device weight is great, vertical support 3 easily takes place to topple over, consequently still needs to set up following structure:
one side of the bracket 3 departing from the lifting plate 6 is connected with the fixed underframe 2 through a supporting rod, and the supporting rod 11 is obliquely arranged. Connect through bracing piece 11 and make support 3 more stable, the unexpected condition that topples over appears in support 3 in can not appearing using to bracing piece 11 of putting to one side can provide better pulling force, constitutes triangle-shaped connection structure, and is stable effectual.
Further, the mechanism fixing plate 9 needs to be detachably connected with the mounting plate 8, and the distance between the mechanism fixing plate 9 and the mounting plate 8 can be adjusted, so as to realize the above function. And is not limited to providing one specification of the mechanism fixing plate 9, the mechanism fixing plate 9 must be provided in a plurality of kinds so as to be suitable for different models. And because the structure of the three-phase linkage breaker spring operating mechanism is different, the distance between the mechanism fixing plate 9 and the mechanism fixing plate 9 also has the adjusting function.
The mechanism fixing plates 9 have a plurality of specifications, and a single three-phase linkage breaker spring operating mechanism needs to be fixed by two mechanism fixing plates 9. Stability is difficult to satisfy only through a mechanism fixed plate 9, and the security can not satisfy current requirement.
After the three-phase linkage breaker spring operating mechanism is fixed by selecting a proper mechanism fixing plate 9, the three-phase linkage breaker spring operating mechanism can realize the advantages of rotation, lifting, convenient movement and the like, and can be normally used in the state, but the structure can be optimized in consideration of the problems of the device in practical application, firstly, in the prior art, the three-phase linkage breaker spring operating mechanism needs to be turned over at a fixed angle in the assembling and experiment processes, the conventional mode is to select a servo motor, the cost of the mode of setting an angle encoder and the like is too high, the device also does not need the technical effect of accurate rotation, the device aims to rotate certain specific angles according to the particularity of the device, so the cost of directly using the servo motor is not acceptable, and the three-phase linkage breaker spring operating mechanism is usually in a plurality of specifications due to the particularity of the application condition of the device, and specifications such as height width length all inequality, consequently need use different mechanism fixed plates 9 fixed to some three-phase linkage circuit breaker spring operating device need rotate 90 °, 180 the equal angle of spare part installation, and must be convenient for discern, need set up a plurality of holes on the mounting panel 8 usually and be applicable to different mechanism fixed plates 9, consequently need select suitable angle, so that install fast, on this basis, this device still needs following optimized structure:
the mounting plate 8 is a polygon with an even number of sides. The mechanism fixing plate 9 can be conveniently installed by rotating to a proper angle, and at least one group of opposite sides of the installation plate 8 are parallel. When any one of the parallel opposite sides of the mounting plate 8 is horizontal, after the mounting plate is rotated by 180 degrees, the opposite sides are also horizontal, so that the mounting plate is convenient to observe, and the rotating angle can be clearly known to be 180 degrees. The three-phase linkage circuit breaker spring operating mechanism is suitable for a three-phase linkage circuit breaker spring operating mechanism which needs to rotate 180 degrees.
Further, all opposite sides of the mounting plate 8 are parallel and equal. The fixed three-phase linkage circuit breaker spring operating device of different models of opposite side of difference to each is convenient for observe, and that can be clear knows turned angle is 180. The spring operating mechanism can be suitable for a plurality of three-phase linkage circuit breaker spring operating mechanisms which need to rotate 180 degrees. When a single opposite side is parallel to the ground, the three-phase linkage breaker spring operating mechanism is fixed on the mounting plate 8 through the mechanism fixing plate 9 and rotates to the opposite side for position exchange, and the three-phase linkage breaker spring operating mechanism can realize 180-degree rotation.
Correspondingly, a horizontal ruler can be arranged at the opposite side of the parallel arrangement of the mounting plate 8, so that whether the side of the mounting plate 8 is parallel to the ground or not can be observed conveniently. And the level ruler has lower cost and is convenient to install and observe. And the level bar can select different colors for use, so that the searching and the observation are more convenient.
In practical applications, since the three-phase linked breaker spring operating mechanisms of different specifications must be rotated by a specific angle when being installed, the following structure is a necessary structure.
The mounting plate 8 is a regular polygon. Regular polygon has stronger effect under specific specification, and preparation and installation can be more convenient, and the effect is when three-phase linkage circuit breaker spring operating device structure differs little, can exert the effect. When installing the little three-phase linkage circuit breaker spring operating mechanism of difference, can select regular polygon to regular polygon has additional function, for example:
when the technical effect that must be rotated 90 ° to be visible is required, it is necessary to choose the mounting plate 8 as a regular octagon. After the three-phase linkage circuit breaker spring operating mechanism rotates 90 degrees, the condition of parallel and level can appear, and the observation is convenient.
When the visual technical effect of 60 degrees and 120 degrees of rotation is needed, a regular hexagon structure is needed, and the situation that one side of the ground is parallel to the ground after the ground is rotated for a certain angle can be achieved. And thus is visible through the level.
And different mechanism fixed plates 9 are connected to the different opposite sides of mounting panel 8, and the mechanism fixed plate 9 that the opposite side is connected fixes a three-phase linkage circuit breaker spring operating device simultaneously, can avoid appearing single opposite side hole too many, the unable condition of fixed mechanism fixed plate 9.
The chassis 2 circumference sets up 4 connecting plates 1, just connecting plate 1 extends to the outside of chassis 2. Can be used to the navigation to hang the hoist and mount and use to can be used to install the wheel and remove, very convenient.
Example 2
The difference from embodiment 1 is that when the mounting plate 8 is a non-regular polygon, as shown in fig. 5, the mounting plate can be applied to a three-phase linkage breaker spring operating mechanism with an irregular shape, and since the visibility of 180 ° rotation is a necessary technical effect, when the three-phase linkage breaker spring operating mechanism with an excessively large difference in length, width and height is fixed, the structure shown in fig. 5 needs to be used, the three-phase linkage breaker spring operating mechanism with a large width can be fixed by using relatively wide parallel opposite sides, and so on, the other opposite sides can fix the corresponding three-phase linkage breaker spring operating mechanism, and whether the three-phase linkage breaker spring operating mechanism rotates 180 ° or not can be clearly obtained, which has a remarkable effect compared with the circular mounting plate 8, and each opposite side can easily distinguish and fix the three-phase linkage breaker spring operating mechanism of that type.
Other features not mentioned in this embodiment can be the same as those in embodiment 1, and are not described again.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or additions or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
