Background technology
Application number is 200810198282.5, the Chinese patent application that open day is on January 21st, 2009 discloses the automatic change-over of a kind of pull-out type band bypass, the body switch can slide in main body frame, therefore, when the body switch need overhaul or change, it can be extracted out from main body frame easily, and then can operate accordingly in the outside of power distribution cabinet, after disposing, this body switch can be inserted in the main body frame again.This shows, the structure of withdrawing device be directly connected to the body switch extract out or when closed can about synchronous problem, if the body switch is discontinuity equalization when action, the body switch will occur owing to closed deviation occurs can't closed problem, and then will directly have influence on the quality of the automatic change-over of pull-out type band bypass.
Summary of the invention
One object of the present invention is to provide a kind of body switch that can guarantee easily to extract out and closed withdrawing device.
The technical solution adopted in the present invention is: comprise driving shaft and two cover driving mechanisms; Described driving shaft is used for being fixedly mounted on by two bearing pedestals the body switch of draw out switchgear electrical equipment; Described driving mechanism comprises gear, tooth bar and extension spring; Wherein, described gear is the part of all gears, and described gear and driving shaft are rigidly connected; Described rack and pinion meshes, and described tooth bar is used to be installed in the base plate of the main body frame of described draw out switchgear electrical equipment as fixture; One end of described extension spring is fixedly connected on the gear, the other end is used for fixing on the connection support that is connected the body switch, described extension spring is used for when extracting described body switch out, after controlling described wheel and rack and throw off by driving shaft, guarantee that described gear is in the state that breaks away from tooth bar all the time after extraction.
Preferably, described two cover driving mechanisms are installed in the two ends of driving shaft respectively, and lay respectively at the outside with the bearing pedestal that is close to separately.
Another object of the present invention provides a kind of body switch that can guarantee and easily extracts out and closed draw out switchgear electrical equipment.
The technical solution adopted in the present invention is: a kind of draw out switchgear electrical equipment comprises main body frame and is installed in the interior body switch of main body frame that the bottom of described body switch is equipped with is convenient to the guide wheel device that it slides in main body frame; Also comprise above-mentioned draw out switchgear electrical equipment withdrawing device, described driving shaft is fixedly mounted on the body switch of draw out switchgear electrical equipment by two bearing pedestals, described tooth bar is installed on the base plate of described main body frame, and the other end of described extension spring is fixedly connected on the connection support of body switch.
Beneficial effect of the present invention is: withdrawing device of the present invention, by the two cover driving mechanisms that adopt, it is the rack-and-pinion motion, just can guarantee the body switch extract out and closing motion in about synchronously, thereby solved the body switch because of discontinuity equalization cause can't closure or have a problem of closed deviation.
Description of drawings
Fig. 1 has the structural representation of draw out switchgear electrical equipment of the present invention with the draw out switchgear electrical equipment of withdrawing device;
Fig. 2 shows the relative position relation of withdrawing device shown in Figure 1 when the body switch is in closure state;
Fig. 3 shows the relative position relation of withdrawing device shown in Figure 1 when the body switch is in the extraction state.
Embodiment
Now in conjunction with the accompanying drawings the specific embodiment of the present invention is described in detail.
Shown in Fig. 1,2 and 3, draw out switchgear electrical equipment of the present invention comprises driving shaft 20 and two cover driving mechanisms 10 with withdrawing device.Described driving shaft 20 is fixedly mounted on by two bearing pedestals 30 on the body switch C of draw out switchgear electrical equipment, and described two cover driving mechanisms 10 are installed in the two ends of driving shaft 20 respectively, and lays respectively at the outside with the bearing pedestal 30 that is close to separately.Described driving mechanism 10 comprises gear 102, tooth bar 101 and extension spring 103; Wherein, described gear 102 is the part of all gears, and itself and driving shaft 20 are rigidly connected, and can rotate with driving shaft 20; Described tooth bar 101 is installed on the base plate of main body frame B of described draw out switchgear electrical equipment, be used for meshing with gear 102, and then the time by spanner 40 rotating driveshafts 20, relative motion can take place with tooth bar 101 in gear 102, and then drive Switch main body C moves in main body frame B, wherein, the bottom of body switch C is equipped with the guide wheel device of being convenient to move 50, and the bottom of main body frame B is connected with base A; The installation sites of tooth bar 101 of described two cover driving mechanisms 10 guarantee that it equates with distance between the guide wheel device 50 that is close to separately.One end of described extension spring is fixedly connected on the gear 102, and the other end is fixedly connected on the connection support of body switch C.The present invention guarantees that by the structure of a driving shaft 20 controls two cover driving mechanisms 10 the body switch can producing balanced forces when moving.
As shown in Figure 1, when needs are extracted body switch C out, press spanner 40 downwards, spanner 40 drives driving shafts 20, and then driven gear 102 clockwise rotates, when gear 102 forwards to when extracting the position out, as shown in Figure 2, gear 102 will be thrown off with tooth bar 101, and at this moment, operating personnel just can continue body switch C outwards to pull out by the handle that is fixed on the body switch C.After described gear 102 is thrown off with tooth bar 101, because the effect of extension spring 103 can guarantee that gear 102 is in the state that breaks away from tooth bar 101 all the time after extraction.
When the closed body switch of needs C; upwards promote spanner 40; spanner 40 drives driving shaft 20; and then the pulling force that driven gear 102 overcomes extension spring 103 rotates counterclockwise; after gear 102 and tooth bar mesh again; just relative motion that can be by gear 102 and tooth bar 101 back into as shown in Figure 2 closure state with body switch C; after body switch C is back into closure state; generally can lock the position of body switch C by stopping means; because stopping means is not to be the content of protection required for the present invention; at this, its concrete structure is not further described.
To sum up institute for preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention only.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
