Description

The invention relates to an auxiliary device for manually rotating a designed as a T-key, manually operable tool for rotating a valve-actuating body of a valve.

In recent years, the awareness of turning or servicing faucets, such as rotary valves, has been very much carried out by the utilities, so that today many faucets work smoother again in the period of their use than before. This is due to the regulations of the DVGW which have been valid for many years and the insight of the suppliers for maintenance measures.

Mild or well maintained valves, such as rotary valves, for shutting off fluid lines, in particular water or gas pipes, in particular those that are installed in the ground, can often be rotated relatively smoothly, but require a high number of revolutions for the closing and opening process. Manually such fittings are usually operated by means of a T-shaped hand key. Such hand keys are also known as underfloor hydrant keys or slider keys or simply called T-keys.

Such a T-key comprises a shaft for torque transmission and a cross member for manual power line, which is rigidly connected to a first end of the shaft with this. The cross member has two mutually away and transversely or perpendicular to the shaft extending cross member body for the manual application of force. The other end of the elongated shaft extending along its shaft axis is provided with an actuating body, which is also referred to as an adapter bell or socket, which fits into a fitting actuating body of the fitting, also referred to as an adapter. The actuating body of the shaft of the T-key is non-rotatable, but again detachable, coupled to the fitting body of the valve.

Such T-keys are actually designed cost-effective and robust for stiff valves and for the increased torques required for their closing and opening, even if only rarely is a high torque retrieved. For the latter case, however, such T-keys must be stable and robust.

In order to achieve a rotation of such fittings by means of such a T-key at an increased speed, an operator had so far had to grip with a first hand, the vertical shaft of the T-key below the two cross-beam body and had with his second hand on the horizontal bar end attack a cross member of the two cross members of the T-key and generate with a correspondingly large radius a continuous ring-round rotational movement or a swinging motion with the help of the flywheel of the crossbars.

This was awkward. There was also the risk of friction-heated heating or even injury to the hand embracing the shaft. In addition, the operator risked a painful collision of the crossbar of the T-key with his body / face. In addition, the known T-keys are usually available by default in only a single height dimension and are sunk in their use partly in the ground or in a slide cap to the adapter of the fitting out, for example, 20 cm. As a result, their operation / rotation is only bent or squat. Especially with a fast manual turning of the coupled with a fitting T-key to its shaft axis of rotation, it can lead to a pulse-like load on the valve, which can lead to a show wear of the valve. For the operator, non-uniform rotation or momentum rotation for rotating such a T-key, but also continuous rotation for rotation of such a T-key, are strenuous in the manner described above.

It is therefore an object of the invention to avoid the above disadvantages.

This object is solved by the features of claim 1. Accordingly, the invention relates to an auxiliary device for manually rotating a trained as a T-key manually operable tool for rotational actuation of a valve, in particular a rotary valve having a along its shaft axis extending shaft for transmitting torque and a cross member with two away from each other and across or perpendicular to said auxiliary device comprises a support for releasably clamping said auxiliary device to said T-wrench adapted to be releasably clamped to said T-wrench, and wherein said retainer is adapted to engage in said T-wrench a clamping body direction, in particular in a clamping body longitudinal direction, extending clamping body and a counter-clamping body which are connected by means of several fasteners together and are rotationally fixed firmly clamped or clamped to the T-key, and wherein the Hilfsvo comprises a rod-shaped first torque transmitting body which extends along its first body longitudinal axis having a first end and a second end facing away from the second end and which is fastened in the region of its first end to the clamping body of the holder, and to which in a longitudinal region between its first end and its second end about the first body longitudinal axis of the first torque transmitting body freely rotatable rotary handle to manual holding of the T-key in a stable axial position and to prevent relative movement between a hand of an operator and the rotary handle when turning the T-key is secured about the shaft axis of the shaft by means of the auxiliary device, and wherein the auxiliary device comprises a hand crank, a second rod-shaped torque transmitting body and a crank handle for manual operation of the crank handle, and wherein the second rod-shaped torque transmitting body extends along its second body longitudinal axis and having a first end and a second end pointing away therefrom, and wherein the zw Torque transmission body is attached in the region of its first end to the first torque transmitting body in the region of the second end and perpendicular to the first body longitudinal axis of the first torque transmitting body can be arranged or arranged, and wherein the crank-rotary handle in the region of the second end of the second rod-shaped Torque transmission body is attached and is freely rotatable about a perpendicular to the second body longitudinal axis extending crank-handle rotary axis of rotation.

With the help of the auxiliary device according to the invention, a slightly common or rotatable adapter or valve actuation body of a fitting with a conventional T-key can be quickly, ergonomically and comfortably rotated in both directions. The annoying implementation of the rotary hand and a friction-induced heating or injury of the holding hand is eliminated.

If the valve is not smooth, you can still use the T-key as usual to exercise a higher torque class, ie directly manually rotate about its cross member about the shaft axis of its shaft. If the valve in a transition phase between a final phase when closing and an initial phase when opening is smooth, but in the initial phase of one to three revolutions and / or in the final phase of one to three revolutions an increased torque for rotating the adapter or valve body of the Fitting is required, the adapter or the valve actuating body of the fitting in the said transition phase can first be rotated by means of the auxiliary device according to the invention via the T-key and then, depending on the direction of rotation, either by means of the auxiliary device according to the invention quickly, easily and safely up to a provisional closing or end stop to be turned and then classic, so directly, be rotated by applying an increased torque by means of the T-key in the final closed position or classic, ie directly with the T-key while exercising a increased torque can be rotated from one or the final closed position into a first rotary opening position, from which then the adapter or the valve actuating body of the valve by means of the auxiliary device according to the invention can be opened quickly, easily and safely. It can therefore be traced over the key spars of the T-key classic and / or in an initial phase, in particular the first 1-3 revolutions are turned on the key spars of the T-key only in a final phase, especially the last 1-3 revolutions , For example, in a fitting with a dimension of 150 mm, about 60 revolutions in a direction of rotation between the full closed position and the full open position of the adapter or fitting actuator body are required. There are thousands of such faucets in a big city. That means that about 54 Revolutions on the auxiliary device according to the invention or by means of the auxiliary device according to the invention are particularly fast, very simple, particularly convenient and particularly safe feasible. As a result, a significantly shorter service time or actuation time is required in comparison with the prior art in a manual operation. In addition, the cumbersome and discontinuous transfer of hands / arms is eliminated, at least in the said transitional phase. Even for the operator, the uniform rotation is more appropriate to the body than a pulse rotation. For the fitting means the possible means of the auxiliary device according to the invention continuous rotary motion has the advantage that their mechanics is less strained and also deposits can better replace.

The auxiliary device according to the invention with your hand crank is suitable for a proper operation for both right-handed and left-handed.

The freely rotatable about the first body longitudinal axis of the first torque transmitting body rotary handle allows a manual gripping or holding the auxiliary device, respectively the T-key, in a stable axis with the hand of an operator, without it when turning the hand crank to the second body longitudinal axis of the second torque transmitting body or when turning the T-key about the shaft axis of its shaft by means of the auxiliary device for forming friction in the hand and / or in a glove tightened above.

The rod-shaped second torque transmission body 22 is in a longitudinal area between its free second end 59.2 and the second axis of rotation 37.2 with a parallel to the second body longitudinal axis 43.2 the rod-shaped second torque transmission body 22 extending slot 64 Provided. Its longitudinal axis 65 extends parallel to the second body longitudinal axis 43.2 of the second torque transmission body 22 , The slot 64 begins near the second end 59.2 of the second torque transmission body 22 and extends axially over slightly less than half the length of the second torque transmitting body 22 , In the cavity 66 of the square tube 22 the second torque transmitting body is a sliding block 67 along the long hole 64 arranged axially displaceable. The nut 67 engages slot edges of the slot 64 , The nut 67 is provided with an internally threaded bore of a blind hole. Into the internal threaded hole is a first end 69.1 an externally threaded, rod-shaped fastening body 68 screwed. In the attachment body 68 it is a threaded bolt and a bearing body on which the crank-turn handle to the mounting body longitudinal axis 70 is freely rotatable. The fastening body 68 extends straight along its mounting body axis 70 , The fastening body 68 is with the nut 67 firmly screwed. At the other, second end 69.2 of the fastening body 68 is the crank-turn handle 25 around its crank-turn-handle-pivot 71 freely rotatably mounted, which is coaxial with the mounting body axis 63 is arranged. The crank-turn handle 25 is not shown ball bearings on a circular cylindrical part of the mounting body 68 at its second end 69.2 around the crank-turn-handle-pivot 71 freely rotatably mounted. Between the crank-turn handle 25 and the opposite outer surface of the rod-shaped second torque transmission body 22 is on the external thread of the fastening body 68 a committed mother 72 screwed on with its internal thread. The feasting mother 72 can against the nut 67 be attracted to the crank-turn handle 25 carrying fastening body 68 against movement relative to the second torque transmitting body 22 set. After a release of the fixed nut 72 by rotating it in a first direction of rotation about the longitudinal axis of the fastener body 70 can the attachment body 68 along with the crank-handle that he carries 25 along the long hole 64 of the second torque transmission body 22 axially, parallel to the body longitudinal axis 43.2 of the second torque transmission body 22 be moved. In this case, the fastening body 68 along with the crank-handle that he carries 25 to any position along the slot 64 moved and can then there again by donating the Festlegemutter 72 by rotating it in a second direction of rotation opposite to the first direction of rotation about the longitudinal axis of the attachment body 70 on the second torque transmitting body 22 be set against a movement relative to this. The fixation along the long hole 64 can be at different radial distances to the second axis of rotation 37.2 respectively.

In the in the 1-5 shown use position 30 the auxiliary device is the hand-crank turning handle about 25-30 cm above the crossbar 15 of the T-key 11 , This is particularly due to the upwardly folded rod-shaped first torque transmitting body 21 achieved, which has a correspondingly adapted length, wherein the first and the second axis of rotation 37.1 . 37.2 are arranged in a correspondingly adapted center distance from each other. This results in the embodiment shown an ergonomic height arrangement of the hand crank 24 from +25 cm to +30 cm above the T-key 11 , This is the hand crank 24 the auxiliary device 10 in an ideal operator position in which an operator 19 in contrast to the situation with a conventional, direct rotary actuation of the conventional T key 11 , in most applications no longer has to bend over. By means of the rod-shaped first torque transmission body 21 So a certain height difference, for example, from 25 cm to 30 cm, can be compensated. This is also more ergonomic and practical when cranking. In addition, no long lever arm for cranking is needed if the valve body 12 is easily rotatable. Then the crank-turn handle 25 in a correspondingly smaller or smaller radial distance from the second axis of rotation 37.2 on the rod-shaped second torque transmitting body 22 be determined. As a result, correspondingly greater rotational speeds, ie greater speeds during cranking are possible, with a correspondingly lower force sufficient for turning for about 98% of the turning operation.

Hereinafter, a method will be described, by means of which the first and second torque transmitting body 21 . 22 the auxiliary device 10 starting from their in the 1-5 shown use positions 31 . 32 in the in 7 shown end folding position 74 is convertible:

In the in the 1 to 5 shown use position 30 the auxiliary device is the first torque-transmitting body 21 in its second locking rotary position 51.2 and use position 31 in which he goes up over the T-key 11 and over the clamp bracket 20 also extends, and is also the rod-shaped second torque transmitting body 22 the winch 24 in its second locking rotary position 61.2 and use position 32 , in which its second body longitudinal axis 43.2 approximately perpendicular to the first body longitudinal axis 43.1 of the first torque transmitting body 21 extends.

Based on these locking rotary positions 51.1 ; 61.1 or use positions 31 . 32 the first and second torque transmitting body 21 . 22 can first of the second locking pin 45.2 manually solved this way, ie manually from the mounting recess 54 of the first torque transmitting body 21 be pulled out, so that the second torque transmitting body 22 relative to the first torque transmitting body 21 around the second axis of rotation 37.2 in his first locking rotary position 61.1 can be turned. After a slight rotation of the second torque transmitting body 22 relative to the first torque transmitting body 21 then can the second locking pin 45.2 be let go. After rotating the second torque transmitting body 22 in his first locking rotary position 61.2 is the second locking bolt 45.2 in the mounting recess 54 the second bracket 52.2 of the first torque transmitting body 21 engaged, as in 6 shown.

Preferably then lies the second torque transmitting body 22 in the area of his second end 59.2 on the first locking plate 36.1 of the first torque transmitting body 21 on.

Starting from this transitional position 73 said assembly 50 can now be the first locking pin 45.1 manually released, ie manually from the first recess 40.1 the first locking plate 36.1 of the first torque transmitting body 21 be pulled out, so that said assembly 50 , starting from the second locking rotary position 51.2 of the first torque transmitting body 21 , relative to the first clamping plate 20.1 the holder 20 around the first axis of rotation 37.1 180 degrees in the first locking rotary position 51.1 of the first torque transmitting body 21 can be turned.

After a slight rotation of the first torque-transmitting body 21 along with the winch 24 relative to the first clamping plate 20.1 can then be the first locking pin 45.1 be let go. After rotating the first torque transmitting body 21 in his first locking rotary position 51.1 is the first locking pin 45.1 in the first recess 40.1 the first locking plate 36.1 engaged, as in 7 shown.

Then there is the unit 50 which the two adjacent torque transmitting body 21 . 22 includes, in its end-folding position 74 , In this end folding position 74 can the operator 19 if desired, the T-key 11 in a conventional manner, ie by direct manual rotation of the two cross-beam body 15.1 . 15.2 of the crossbar 15 by means of his two hands. This example, the fitting actuator body 12 either in a final phase, ie the last one to three turns to tighten or in an initial phase, so the first one to three turns to solve. When the auxiliary device 10 is present separately, ie from the T-key 11 dissolved and removed from this, it can in the said end-folding position 74 be transported or stored in a particularly space-saving manner.

Dismantling, ie loosening and removing the T-key 11 from the auxiliary device 10 , can in the in the 1 to 5 shown use positions 31 . 32 of the first and second Torque transmission body 21 . 22 respectively. For this purpose, the four screws 26.1 . 26.2 . 26.3 . 26.4 from the threaded holes 28.1 . 28.2 . 28.3 . 28.4 the second clamping plate 20.2 be unscrewed. Subsequently, the second clamping plate 20.2 be lifted off or on what or where the T-key 11 can be taken away.

When the auxiliary device 10 and the T-key 11 According to the invention are attached to each other, so form a common key assembly, the auxiliary device 10 as a mini-key in the power key (T-key). The one with the auxiliary device 10 equipped control key (T-key 11 ) then has a double function. Compared to the weight of the separate T-key 11 has the key assembly according to the invention only a relatively small excess weight. A classic T-key 11 usually weighs about 8 kg and the auxiliary device 10 weighs only 1 kg, so that results in a total weight of the key assembly of only 9 kg.

The auxiliary device according to the invention 10 is compact, space-saving collapsible and does not hinder the conventional turning of a so equipped T-key 11 ,

Based on the positions of use 31 . 32 the first and second torque transmitting body 21 . 22 the auxiliary device 10 in their position of use 30 for turning the T-key 11 , need help with the auxiliary device 10 only two spring-loaded locking bolts 45.1 . 45.2 be solved to the end-folding position 74 to get. Starting from the end folding position 74 can the auxiliary device according to the invention 10 can be unfolded in a simple way in just five seconds and made operational, and vice versa.

The auxiliary device according to the invention 10 It also has the advantage of being quickly and easily prepared for any compatible T-shape control key on the market. By means of only four screws 26.1 . 26.2 . 26.3 . 26.4 and the only two clamping plates 20.1 . 20.2 is a clamp-mounting for different shaft diameter of the shafts of the commercial operating key (T-key) very simple and stable.
