Abstract
The utility model belongs to a hand-operated rod device which mainly comprises a pull rod and a lead screw; the front end of the pull rod is provided with a joint; the rear end of the pull rod is fixedly connected with one end of the lead screw; a square nut is screwed on the lead screw; the square nut at one side of the pull rod is connected with a supporting seat by a bearing shaft; and an adjusting locknut is arranged on the lead screw and between the pull rod and the lead screw. The hand-operated rod device is convenient for an operator to adjust a circuit breaker to a suitable position during the assembling process, can be assembled and maintained conveniently, and has the advantages of having simple structure, being used safely and reliably, saving operation time, having low cost, saving time and effort, and being convenient to carry.
Description
Technical field
The utility model belongs to a kind of hand-power function lever apparatus.
Background technology
Circuit breaker is a condition in accordance with regulations, the device for switching that power distribution circuit, motor or other power consumption equipments are carried out make-break operation and shielded.When overload, short circuit or situation such as under-voltage appear in circuit, can divide deenergizing automatically, be the main protection switch of distribution line and power consumption equipment, circuit breaker also can not connected and branch deenergizing and control motor under normal operation continually simultaneously.
On the other hand, circuit breaker is in core status in Cubicle Gas-Insulated Switchgear, especially when being short-circuited fault and normal operating condition, all need closure and breaking circuit breaker, therefore need the position adjustment of circuit breaker is accurate when assembling, suitable, but because the breaker operator function of Cubicle Gas-Insulated Switchgear 126kV or 252kV electric pressure is all very big, need during assembling simultaneously three-phase to be adjusted, owing to there is not operation tool, depend merely on by hand and can't adjust operation, make the staff after assembling, can not judge circuit breaker whether install suitable, the phenomenon that causes circuit breaker to break down when operation happens occasionally, and has reduced the useful life of circuit breaker significantly.
Summary of the invention
The purpose of this utility model is a kind of hand-power function lever apparatus of design, can make things convenient for the staff when assembling circuit breaker to be adjusted to suitable position, is easy to install and maintain, have simple in structurely, safe and reliable, can save the activity duration, cost is low, saves time, laborsaving and portable advantage.For this reason, the utility model mainly is made up of pull bar and leading screw, and the pull bar front end is provided with joint, an end of the affixed leading screw of back end of tie rod, and the spiral shell side of being provided with mother on the leading screw is positioned at that the side of pull bar one side is female goes up by the bearing supporting seat that is coupling.Screw mandrel between the described and pull bar is provided with the adjustment clamp nut.The said structure design has realized the purpose of this utility model.
The utility model advantage is to make things convenient for the staff in when assembling circuit breaker to be adjusted to suitable position, is easy to install and maintain, and has simple in structurely, safe and reliable, can save the activity duration, and cost is low, saves time, laborsaving and be easy to carry.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, a kind of hand-power function lever apparatus mainly is made up of pull bar 2 and leading screw 6, and the pull bar front end is provided with joint 1, an end of the affixed leading screw of back end of tie rod, and the spiral shell side of being provided with is female 5 on the leading screw, is positioned at that the side of pull bar one side is female goes up by bearing 7 supporting seat 4 that is coupling.
Screw mandrel between the described and pull bar is provided with adjusts clamp nut 3.Back end of tie rod can be spirally connected with an end of leading screw, adjusts affixed pull bar and leading screw with the adjustment clamp nut again, like this, can conveniently adjust the distance between pull bar and the leading screw.
During use, when in assembling process, adjusting circuit breaker, supporting seat and Shell of circuit breaker seat are fixed, joint on the pull bar is fixed by the hole on bearing pin and the circuit breaker connecting lever, side on the rotational lead screw is female, drive a screw mandrel and a pull bar left side, move right, circuit breaker is adjusted to closing position or separating brake position, the staff is by rotation side's mother stock, close circuit breaker and can judge the circuit breaker branch, whether normal, it is suitable to show whether circuit breaker is installed, after circuit breaker is adjusted to correct position if closing a floodgate, joint is separated with the circuit breaker connecting lever, unload supporting seat and get final product, it is time saving and energy saving to operate, and has saved staff's operating time significantly.
In a word, of the present utility model is to make things convenient for the staff in when assembling circuit breaker to be adjusted to suitable position, is easy to install and maintain, and has simple in structurely, safe and reliable, can save the activity duration, and cost is low, saves time, laborsaving and be easy to carry.
