Abstract
The utility model discloses a torque wrench for a valve handwheel. The torque wrench comprises a wrench body. The wrench body comprises a wrench handle and an operating socket connected to the end of the handle. The torque wrench is characterized in that an auxiliary bar is arranged at the other end of the wrench handle. The torque wrench for the valve handwheel allows moment of force to be prolonged to increase torque according to conditions, allows a single person to operate in narrow space, and is laborsaving and convenient to use.
Description
Technical field
The utility model relates to a kind of spanner, and especially a kind of valve handle moment of power of can borrowing is pulled.
Background technology
When Hydropower Plant maintenance or isolation, often run into one man operation's valve in narrow space, and because big single can't the operation of valve, if the method that adopts single nothing machinery instrument to assist opens or closes valve, effect is often not so good, not only require great effort but also time-consuming, and it is not in place valve operation to occur, has brought serious hidden danger for the safe operation of equipment.
Summary of the invention
The utility model provides a kind of valve handle moment to pull at above problem, and this routine valve handle moment is pulled and can be prolonged moment according to circumstances and increase moment of torsion, can single operation in small space, thus reach purpose laborsaving, easy to use.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of valve handle moment is pulled, and comprises wrench body, and described wrench body comprises that pinch bar is pullover with the work that is connected handle end, and the described pinch bar other end is provided with auxiliary rod.
Further, described auxiliary rod and pinch bar are hinged.
Further, also include connecting rod, the detachable auxiliary rod that is fixed on of an end of connecting rod, the other end is hinged on the pinch bar.
Further, described connecting rod is slidingly located on the pinch bar, and glide direction is vertical with the bearing of trend of pinch bar, and the other end of connecting rod is the L type, and auxiliary rod is provided with the jack corresponding with connecting rod L end.
Further, the middle part of connecting rod is the bending structure.
Further, described connecting rod is towards the wrench body outside curve.
Operation principle of the present utility model and beneficial effect show:
The utility model is provided with auxiliary rod at the rear portion of existing pinch bar, and this kind auxiliary rod can effectively prolong existing moment, has increased moment of torsion under same power effect, thereby realizes easily valve being rotated; Has simple in structure, time saving and energy saving, effective advantage.
Described auxiliary rod and pinch bar are hinged, and auxiliary rod can be around rotation like this, thereby are contained in a side of pinch bar, and area occupied is little, and is easy to carry.
By being provided with connecting rod, it is hinged on auxiliary rod and the handle, and connecting rod can carry out spacing to auxiliary rod like this.
As seen, the utility model has prolonged moment by auxiliary rod is set, thereby reaches the single purpose of easily passing through the spanner by-pass valve control.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, the accompanying drawing that describes below only is some embodiment that put down in writing among the application, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings;

Fig. 2 is the utility model plan structure schematic diagram.
The specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
In order to make those skilled in the art person understand technical scheme among the application better, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all should belong to the scope of the application's protection.
Shown in Fig. 1-2, a kind of valve handle moment is pulled, and comprises wrench body, and described wrench body comprises that pinch bar 1 is pullover with the work that is connected handle end.
The hinged auxiliary rod 3 that is provided with of described pinch bar 1 other end,
The end of pinch bar 1 is provided with the cross bar perpendicular to the pinch bar bearing of trend, be arranged with connecting rod 2 on the cross bar, the other end of connecting rod 2 is the L type, auxiliary rod 3 is provided with a plurality of jacks corresponding with L type termination, connecting rod 2 is positioned at the medium position of the bearing of trend of handle like this, the middle part of connecting rod 2 is bandy shape, is used for holding the pin joint of pinch bar 1 and auxiliary rod 3, prevents that it from interfering with each other.
During use:
1, at first valve handle moment is pulled and be enclosed within on the valve, according to the fixing handwheel torque spanner of the size of valve.
2, the direction of the valve of clearly opening or closing is selected handwheel torque spanner direction of rotation as required.
3, choose the length of operating grip according to on-site actual situations.
4, operate on it.
The above only is the application's preferred embodiment, makes those skilled in the art can understand or realize the application.Multiple modification to these embodiment will be apparent to one skilled in the art, and defined General Principle can realize under the situation of the spirit or scope that do not break away from the application in other embodiments herein.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
