Abstract
A kind of terminal box of transformer substation chamber door multi-angle fixture, it is linked in sequence with spring clamp, universal joint, expansion link, spring clamp and universal joint standing part are connected to form a composition element, adopt the two ends of the universal joint movable part difference connection expansion link of two this composition elements.Utilize the tight chamber door of spring clip clamp and casing, the elevation angle that the multi-angle rotation of universal joint can adapt to connect chamber door and casing is poor, and expansion link changes the adjustment of length realization to opening angle.
Description
Technical field
The utility model relates to a kind of terminal box of transformer substation chamber door multi-angle fixture, in order to realization fixing multiple opening angles of chamber door.
Background technology
At present, the chamber door of (the being referred to as terminal box herein) casing such as terminal box, mechanism case, central console in transformer station's high pressure place is divided into not fixable type and fixable type: can not fixed chamber door after unlatching cannot and casing between keep fixed angle, chamber door can arbitrarily swing; The chamber door of fixable type utilizes a regular length or telescopic Metallic rod usually, realizes being fixed on a certain special angle after chamber door is opened.
There is following problem in not fixable chamber door: one, chamber door cannot fixedly cause chamber door in the environment of wind to swing back and forth, and affects staff to the work in casing.Particularly when staff carry out drawing contrast, the fine work such as terminal is searched, loop measurement time, collided by chamber door and will have a strong impact on working properly carrying out, even likely therefore cause the faults such as terminal dislocation, circuit in series, DC earthing.Two, fix owing to lacking device, likely because personnel overexert accidentally or wind-force causes the amplitude of oscillation excessive, make chamber door open angle excessive, cause the earth connection between connection chamber door and casing or heater power lead etc. to come off and rupture, form potential safety hazard.
The chamber door of fixable type, because it is fixed on certain special angle usually only, same exist certain inconvenience: mainly cannot meet multi-purpose demand.The fixed form of single angle position, general angle of release is 120 degree, can meet the demand of one-man job, but then to seem insufficient space for the scene of many people cooperating, centralized training etc.
Therefore, production one can carry out multiple opening angle stationary device to terminal chamber door, is the active demand of substation operation maintenance work.
Summary of the invention
In order to overcome existing terminal chamber door without fixture or the deficiency only having single angle fixing device, the utility model provides one can carry out multiple angle stationary device to terminal chamber door, this device can not only realize multi-angle fixed function, and can the chamber door of good compatible various ways and size, structure is simple, simple operation.
The utility model is linked in sequence by spring clamp, universal joint, expansion link, it is characterized in that: spring clamp and universal joint standing part are connected to form a composition element, adopts two of the universal joint movable part difference connection expansion link of two this composition elements.Wherein, universal joint realizes 360 degree of rotations by horizontal rotating disc, and vertical dwang realizes 180 degree of rotations, whole universal joint can realize the angle change of half sphere, adopt universal joint linking springs clamp and expansion link, utilize its flexibility, the elevation angle adapted between chamber door and casing is poor.Expansion link adopts the form of internal and external double-layer, the fixing point of a retractable proj ection installed by interior pipe, and outer tube arranges a fixing hole every a segment distance, is placed in the position of different fixing hole by fixing point, adjustment total length, reaches the target controlling chamber door folding angle.The beneficial effects of the utility model are, can to terminal chamber door carry out multiple angle fixing while, extensively can be adapted to the terminal box of all kinds of form by special structural design, improve the fail safe of equipment and personnel, apparatus structure is simply easy to operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.

1. clamp movable part, 2. springs, 3. clamp standing part, 4. universal joint horizontal rotating disc in figure, the 5. vertical dwang of universal joint, 6. pipe in expansion link, 7. expansion link outer tube, 8. fixed projection
Embodiment
In Fig. 1, Fig. 2, Fig. 3, clamp movable part (1) is pressed down, spring (2) is compressed, the opening between clamp movable part (1) and clamp standing part (3) is made to meet the brim-portion thickness of terminal case body, unclamp clamp movable part (1), utilize the pressure of spring (2) to be fixed on terminal case body by one end clamp of fixture.Same method of operation, is fixed on the clamp of the other end on terminal chamber door.Because universal joint horizontal rotating disc (4) can realize 360 degree of rotations, the vertical dwang of universal joint (5) can complete 180 degree of rotations of perpendicular, therefore the difference in height that can meet between terminal case body and terminal chamber door, also freely can rotate along with the difference of opening angle, make the stationary state that clamp remains unchanged.By the change of the relative position of pipe (6), expansion link outer tube (7) in expansion link, realize adjustment length of telescopic bar, and utilize fixed projection (8), block the reserved fixing hole of diverse location, just can realize the fixing of length of telescopic bar.Utilize leg-of-mutton principle, the adjustment of complete paired terminals chamber door opening angle and fixing, as shown in Figure 5, Figure 6.
Claims (3)
1. a terminal box of transformer substation chamber door multi-angle fixture, be linked in sequence by spring clamp, universal joint, expansion link, it is characterized in that: spring clamp and universal joint standing part are connected to form a composition element, adopt two of the universal joint movable part difference connection expansion link of two this composition elements.
2. terminal box of transformer substation chamber door multi-angle fixture according to claim 1, it is characterized in that: universal joint realizes 360 degree of rotations by horizontal rotating disc, vertical dwang realizes 180 degree of rotations, whole universal joint can realize the angle change of half sphere, adopt universal joint linking springs clamp and expansion link, utilize its flexibility, the elevation angle adapted between chamber door and casing is poor.
