Description

Portable F spanner of double quick operation adjustable moment

Technical Field

The utility model relates to a valve operation tool specifically is a portable F spanner of double quick operation adjustable moment.

Background

The F wrench is named as an English letter F because the shape of the product is like an English letter F, and is also called as an F-shaped wrench, a valve wrench, an F-shaped valve wrench, a valve hook wrench and the like; the F wrench is commonly used in the operation of valve switches involving circular handwheels in power plants and related industries. In the actual operation process, the situation that the resistance is too large when some valves are opened and closed, the valves are not easy to operate or the valves need to be operated quickly in emergency is found, but the existing F wrench is difficult to operate and does not have operation conditions.

The existing F wrench handles are both single-person operated wrenches, and have the following disadvantages in practical application:

1. when a valve with larger resistance is encountered, the valve can be operated only by adding the sleeve to increase the length of the handle, but the method reduces the working efficiency, and the valve with limited position cannot be used.

2. When the valve with more valve turns is encountered, only two or more people can operate the valve alternately, so that the labor is not saved, and the time is consumed.

3. When a large valve needs to be opened and closed quickly in emergency, the valve is difficult to be opened or closed in time.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, provides a portable F spanner of double quick operation adjustable moment for under emergency, double quick operation and the moment that can realize the F spanner are adjustable to solve above-mentioned problem.

In order to achieve the above purpose, the present invention is achieved by the following technical solutions.

A portable F wrench capable of being rapidly operated by two persons and adjusting torque comprises a wrench handle and a movable F claw; the wrench handle is provided with a sliding groove along the axial direction, and a plurality of limiting holes are formed in the wrench handle at the sliding groove; the movable F claw is of a door-shaped structure; a connecting hole is formed in the transverse connecting arm of the movable F claw; the movable F claw is inserted into the sliding groove and detachably connected with the connecting piece of the limiting hole through the insertion connecting hole.

Furthermore, the limiting holes are uniformly arranged along the axial direction of the wrench handle.

Furthermore, a thread is arranged in the limiting hole.

Further, the connecting piece is a limiting bolt.

Further, the sliding groove is arranged in the middle of the wrench handle.

Furthermore, two connecting holes are formed in the movable F claw.

The utility model discloses produced beneficial effect does for prior art:

compared with the existing F wrench, the portable F wrench with double quick operation and adjustable torque of the utility model can adjust the torque according to specific conditions, and is labor-saving in operation; and the quick operation can be realized in emergency, and the quick processing can be realized in accident condition. Furthermore, the utility model has the advantages of change the volume little, the small investment, the time limit for a project short, long service life, maintenance work volume little to current F spanner. The utility model discloses rational in infrastructure, design benefit, the resistance is too big when effectively having solved current F spanner operation time switch, can not the rapid operation scheduling problem.

Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1, the portable F-shaped wrench capable of adjusting torque and being operated quickly by two persons comprises a wrench handle 1 and a movable F-claw 5; the wrench handle 1 is provided with a sliding groove 4 (see fig. 3) along the axial direction, and the sliding groove 4 is arranged in the middle of the wrench handle 1. Seven limiting holes 2 are uniformly formed in the position, located in the sliding groove 4, of the wrench handle 1; the limiting hole 2 is internally provided with threads. The movable F claw 5 is in a door-shaped structure (see figure 2); two connecting holes are formed in the transverse connecting arm of the movable F claw 5; the distance between the two connecting holes is equal to the distance between the two adjacent limiting holes 2; the movable F claw 5 is inserted into the sliding groove 4 and is detachably connected with the limiting bolt 3 of the limiting hole 2 through an insertion connecting hole.

This embodiment is the transformation that the current operation spanner that has circular hand wheel valve goes on that combines, the spout has been seted up on handle body surface, have the spacing hole of screwed on the spout, activity F claw 5 passes spout 4, two spacing bolts 3 have been cup jointed at the head both ends of activity F claw 5, activity F claw 5 can remove in spout 4 with adjusting torque, through in the spacing hole 2 of twisting spacing bolt 3 on the spout 4, thereby fix activity F claw 5 on the handle body, adjust double F spanner both ends moment with this, make the better staff that is applicable to various strength and different sizes of this F spanner. As shown in figure 1, the F-shaped wrench F is arranged in the middle of the handle, and the handles at two ends can be used for two persons to operate the valve hand wheel simultaneously. When the adjustable torque portable F wrench is used, two persons face the two sides of the valve of each station, after the torque is rapidly adjusted according to the strength of two persons, the two persons hold the portable F wrench capable of adjusting the torque, the F claw is clamped into the valve hand wheel, and the valve is screwed clockwise or anticlockwise to close or open the valve.

Compared with the existing F wrench, the portable F wrench with the double-person quick operation and the adjustable torque can adjust the torque according to specific conditions, and is labor-saving to operate; and the quick operation can be realized in emergency, and the quick processing can be realized in accident condition. Furthermore, the utility model has the advantages of change the volume little, the small investment, the time limit for a project short, long service life, maintenance work volume little to current F spanner. The utility model discloses rational in infrastructure, design benefit, the resistance is too big when effectively having solved current F spanner operation time switch, can not the rapid operation scheduling problem.

The above description is for further details of the present invention with reference to specific preferred embodiments, and it should not be understood that the embodiments of the present invention are limited thereto, and it will be apparent to those skilled in the art that the present invention can be implemented in a plurality of simple deductions or substitutions without departing from the scope of the present invention, and all such alterations and substitutions should be considered as belonging to the present invention, which is defined by the appended claims.
