Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. 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. Only through being connected of drive lead screw 5 and lead screw seat 51, lifter plate 6 takes place to rotate easily, consequently, need set up corresponding stop device, realize the elevating movement of lifter plate 6's vertical direction, and with regard to the structure, set up spacing guide bar 4 in the both sides of drive lead screw 5, and the symmetry sets up, just can guarantee that lifter plate 6 is straight from top to bottom, can not take place the pivoted condition, and structural stability also can be fine, drive lead screw 5 needs to connect drive arrangement, consequently, it connects on drive lead screw 5 to need drive arrangement (generally be driving motor), and directly link the most suitable and convenient mode with the drive shaft, consequently, can set up motor mount table 10 in the top of drive lead screw 5, set up driving motor at motor mount table 10 drive lead screw 5 and rotate, and this structure installation maintenance is more convenient, and do not occupy the lower space, lifter plate 6 can descend to 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:
the surface that lifter plate 6 deviates from support 3 is provided with revolving stage 7, revolving stage 7 is connected with mounting panel 8, mounting panel 8 for lifter plate 6 can rotate, common structure among the prior art can be chooseed for use to revolving stage 7, therefore no longer give unnecessary details, but concrete installation position does, below at lifter plate 6 sets up drive unit installation department 61, be used for installing drive arrangement, and drive arrangement need connect and drive rotation actuating lever 71 and rotate, again by rotating actuating lever 71 drive driving piece 72 and rotating, and then drive carousel 73 and rotate, it is rotatory later to drive mounting panel 8 by carousel 73, here, can choose the worm gear structure for use, driving piece 72 is the worm promptly, and carousel 73 is the worm wheel, the worm rotates and drives the worm wheel and rotates the realization function, it is also better to realize that the structure is convenient for look for and rotate the effect, corresponding other similar structures also can.
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 the three-phase linkage breaker spring operating mechanism is heavy, the vertical bracket 3 is easy to topple, and therefore the following structure is also arranged:
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 support 3 appears empting 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 selecting suitable mechanism fixed plate 9 to fix three-phase linkage circuit breaker spring operating mechanism, three-phase linkage circuit breaker spring operating mechanism just can realize rotating, go up and down and be convenient for advantage such as removal, can normally use under this state, but consider the problem that this device appears in practical application, can also carry out configuration optimization, firstly, in the existing situation, three-phase linkage circuit breaker spring operating mechanism is in assembly and experimentation, need carry out the upset of fixed angle, and conventional mode is for selecting servo motor, it is too high to set up mode cost such as angle encoder, and this device also need not accurate pivoted technical effect, the purpose of this device is exactly to rotate some specific angles according to the particularity of device, therefore the cost of directly using servo motor is difficult to accept, and because the particularity of this device application, three-phase linkage circuit breaker spring operating mechanism is usually a plurality of specifications, and specification such as height width length all is inequality, therefore need use different mechanism fixed plate 9 to fix, and some three-phase linkage circuit breaker spring operating mechanism need rotate 90 °, angle such as 180 ° carry out the zero part installation, and must be convenient to discern, be applicable to be set up different mechanism fixed plate 9 usually, therefore need to optimize a plurality of suitable mechanism fixed plate 9, this needs to be installed in order to this quick the following device, this basic structure to still need to select this, this a plurality of this:
the mounting plate 8 is a polygon with 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 rotate 180 degrees.
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 for when three-phase linkage circuit breaker spring operating device structure differed not greatly, 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.
