Description

The invention relates to an installation kit for operating underground fittings for connection to pipelines, with a rod that can be operated using a mobile rotary device and is surrounded by a sleeve tube.

When developing residential and industrial areas, fresh water pipes, drains and other pipes are laid in the road substructure. In some cases, the connections to the customers are only made afterwards, which is why installation sets are provided at regular intervals, which enable the connection to the customers or via which the respective lines can be shut down or opened in sections. The DE 295 16 158 mentioned. The use of mobile rotary or slider rotary devices is known. The mobile rotating device is placed on the installation set and the device is switched on. On long booms, the water workers have to use their physical strength to counteract the torque for the valve actuation, which of course can lead to significant impairments. It is known from DE 10 2006 015 325 a device for operating fittings in underground installations, with a non-rotatable receptacle being arranged at the operating point, which consists of at least one transportable and at least one stationary part. A non-rotating mount absorbs the reaction torque that occurs and passes it on to the surrounding soil. With this solution, however, the anti-twist protection must be installed in the form of the support plate with the surface box. In practice, this means: either the anti-twist base plate is installed at the same time when the new building is built, or the existing surface box and base plate are removed and replaced with the non-twist base plate to be built in. The road surface is damaged, which can result in frost damage, subsidence and other impairments.

The object of the present invention is to create an installation kit for operating underground fittings for connection to pipelines, which is characterized by improved absorption of the reaction torque and a simple and safe design.

This object is achieved according to a first embodiment of the invention by an anchoring counteracting the twisting of the mounting fitting in the soil surrounding it, the anchoring being integrated into an outer tube surrounding the sleeve tube.

The object of the invention is therefore in particular a mounting set-side anchoring in the ground and thus a device that allows the water worker to turn it on "force-free" and to initiate the counter-torque to the valve actuation torque via the mounting set and, if necessary, other components in the ground. The outer tube, which is designed as an earth dowel, remains anchored and installed in the ground so that it cannot twist. Since the anchoring is integrated into the outer tube surrounding the sleeve tube or is a component thereof, a special outer tube is realized which still surrounds the sleeve tube and has an uneven contour to the effect that the anchoring mentioned can form. This solution can be built into an existing support plate and surface box without much effort.

In order to make the use of additional fastening means superfluous, such an anchoring via the outer tubes is recommended, in particular it is provided that at least one cross-sectional enlargement in the outer tube serves as anchoring. The outer tube does not have a classic round contour, but at least an extension of the cross section, which is then more or less protrudes outwards and thus forms a wedge, which counteracts twisting when installed.

In this sense, the suggestion that the cross-sectional enlargement is wedge-like, just to create this uneven contour, which then contributes to creating an optimal anchoring of the mounting fittings in the surrounding soil, is understood.

For the purpose of an even distribution of forces, it is considered that the outer tube comprises a plurality of cross-sectional enlargements positioned at equal distances from one another.

Additional flexibility for the use of the device according to the invention can be achieved if the outer pipe has at least one fold-out wedge for anchoring the mounting set in the ground. These wedges are folded out of their position resting against the outer pipe, so that the wedges can be driven into the ground at a suitable point, which gives the installation kit according to the invention additional options for adapting to the local conditions.

An advantageous embodiment of the invention provides that the outer tube extends approximately over the upper third to the upper half of the installation set and thereby encloses the sleeve tube.

In order to implement the mentioned wedge effect, the invention provides that the outer tube has an outer contour that permits a torsion-resistant connection to a transportable actuating device. The inner contours of the protective tube of the actuating linkage preferably correspond to the outer contours of the outer tube

In this context, an additional embodiment of the invention provides that the installation fittings are fitted with one on the installation fittings attachable actuating linkage, via which the installation set can be operated from the control center. To do this, the actuating linkage is placed on the installation set and when the valve slewing device is switched on, a connection is made that is secured against twisting, so that the counter-torque to the valve actuating torque can be introduced into the ground. Instead of an installation set and an operating linkage, one could also speak of a two-part installation set, with a lower and an upper part to be connected in the area of the surface box.

It is envisaged that the actuating linkage is surrounded by a torque-transmitting protective tube, which has a closing ring at its lower end, which has a torsion-proof positive inner contour corresponding to the outer tube and its outer contour.

According to a further advantageous embodiment of the invention, it is provided that the actuating linkage is designed to be telescopic in order to enable better handling and height adjustment, which at the same time significantly reduces the physical impairment of the water workers.

With regard to the invention in concrete terms, the installation set and the actuating linkage are connected to one another via a polygon or a coupling sleeve. The polygon sits at the upper end of the installation set, the coupling sleeve corresponds to this at the lower end of the actuating linkage. The latter, in turn, is surrounded by a sleeve tube and ends with an end cap at the lower end.

According to the invention, it is further provided that the upper end of the actuating linkage is used to connect a mobile rotary device.

A preferred embodiment of the invention provides that a centering is provided between the outer pipe and the edge cap of the installation set, so that the outer pipe and installation set are automatically positioned centered on one another.

In concrete terms, this means that the upper end of the outer tube includes an inwardly directed collar that has a bevel. The collar also tapers inwards, so that the collar together with the bevel corresponds to the edge cap and there is a latching connection, at least in a broader sense.

The outer pipe can be connected to the installation set in a tension-resistant manner by means of a fastening means, preferably one or more screws. The screw penetrates a receptacle provided in the collar of the outer tube and/or the wheel cap.

In addition, a trigger safety device is proposed. Most expediently, a trigger safety is provided between the outer tube and the closing ring at the lower end of the actuating linkage. It is therefore to be understood that a trigger safety device is provided between the outer tube and a closing ring.

A preferred embodiment provides that the trigger safety device comprises a pin which is held in position by a circumferential ring in a resilient manner. i.e. This comparatively small pin is pressed into position by a surrounding, flexible ring and snaps into a groove on the earth dowel.

According to the second variant of the invention, the object is achieved by an anchoring counteracting the twisting of the installation set in the form of at least one dowel driven into the ground.

While the subject matter of the previous explanations relates to a mounting kit, which includes a wedge to be fixed in the ground and which is assigned to the outer pipe, the following is a technically less demanding solution with dowels that are driven into the ground. This means that the anchoring comprises at least one dowel used to anchor the installation set in the ground. Especially when using several, evenly distributed dowels, this solution proves to be advantageous and comparatively easy to implement. In addition, it is provided that the dowel has a thread in order to make it even easier to drive it into the ground.

For good handling of the dowels, it is also provided that the dowels are jointly assigned to an end cap to be connected to the end ring in order to realize the torsion-proof connection.

In order to optimize the production of the connection between the end cap and the dowels, the end cap should have receptacles for the dowels.

For the purpose of simplifying the insertion of the dowels into the ground, it is provided that the closing ring of the actuating linkage is equipped with webs aligned parallel to the dowels.

In addition to this, it is provided that the webs are designed and arranged to correspond to the dowels.

The invention is characterized in particular by the fact that an installation fitting is created for operating underground fittings for connection to pipelines, which works gently for the water workers. In addition to a sleeve tube, the rods of the installation kit also enclose an outer tube from the outside. In a first variant of the invention, this outer tube has the task of exerting a wedge effect on the mounting set in the ground. To do this, the outer tube is driven into the ground. Because it However, it does not have a classic round cross-section, but an extension, is used to anchor this outer tube in the ground. In addition to expanding the cross-section in a kind of bulge, a solution is also possible in which one or more wedges can be folded out in order to then implement anchoring in the ground. The invention also relates to an actuating linkage that can be placed on the installation set by means of a polygonal/coupling socket connection.

An alternative embodiment of the invention provides that one or more fasteners in the form of dowels, if possible provided with a thread, serve to anchor the set in the ground.

figure 1 shows a mounting set 1 in the installed state. The mounting set 1 has a sleeve tube 3 surrounding the linkage (not visible here), which terminates at the bottom with a bell adapter 35 and conceals the connection between the fitting 5 and the pipeline 6 by means of a coupling sleeve. In the upper area of the mounting kit 1, the anchorage 2 designed as an outer tube 4 below the support plate 37 can be seen. The outer tube 4 has an uneven, wedge-like cross-section for the purpose of optimal anchoring of the mounting kit 1 or outer tube 4 in the surrounding soil. At its upper end 39, the mounting kit 1 closes in the street cap 40.

In figure 2 the mounting set 1 with attached actuating linkage 13 with the protective tube 16 is now shown for this purpose. A mobile rotary device 7 can be seen here at the upper end 17 of the actuating linkage 13 . The slider rotating device 7 is attached to the assembly of installation fittings 1 and actuating linkage 13, so that the water worker can now switch on this device 7 "without force", whereupon the counter-torque to the valve actuating torque is introduced into the earth.

For this shows figure 3 an actuating linkage 13 with the attached rotary valve device 7 at the upper end 17 of the actuating linkage 13. This includes a key rod 42, which is at its lower end with a Coupling sleeve 15 is connected. Finally, the actuating linkage 13, more precisely, its protective tube 16 has a closing ring 26 at its lower end 30. Its purpose is the torsion-proof connection to the outer tube 4.

In figure 4 an outer tube 4 or adapter is shown. The outer tube 4 includes an upper end ring 60 with the receptacles 61, 62 and including the actual anchorage 2 in the form of wings 31, 32 as a cross-sectional enlargement 8, which dig into the ground.

A variant of this is shown figure 5 , here in the form of an installation set 1 with a bell adapter 35 and a comparatively long outer tube 4 with a large number of wings as cross-sectional extensions 8 in the area of the outer contour 33, of which only two are given the reference symbols 31 and 32 here as an example. With the polygon 36 for placing the actuating linkage 13 is still called.

The upper part of an outer tube 4 then shows figure 6 with the receptacles 61, 62 for the pins, not shown here, for the second variant of the invention.

Another geometry for an outer tube/adapter 4 shows figure 6 with the wings 31, 32 for anchoring the outer tube 4. The latter has on its closing ring 60 at the upper end of receptacles 61, 62 for the purpose of connection between the actuating linkage and the outer tube 4.

For this shows figure 7 an outer tube/adapter 4 with fold-out wedges 9 - 11 for the purpose of improving the wedge effect, with variants of a folding mechanism naturally being practicable.

In figure 8 an outer tube/adapter 4 is again shown. For better assembly, these can consist of two halves that can be screwed together to form one component.

is shown in figure 9 then the centering 46 between the outer tube 4 and the edge cap 45. The focus here is on the bevel 49, which corresponds to the inwardly directed collar 47 at the upper end 48 of the outer tube 4. It is easy to see how there must be an automatic centering between the outer tube 4 and the edge cap 45 during assembly.

A fixation between the outer tube 4, more precisely the collar 47 and the edge cap 45 then shows figure 10 with the special reference to the fastening means 50 in the form of a screw, which corresponds here to a receptacle 65 in the centering 47.

For this shows figure 11 the trigger safety 51 in the form of pin 52 held in position by a flexible ring 53. The pin 62 snaps into the centering 47 or into any other conceivable component with a corresponding receptacle.

figure 12 Figure 12 illustrates trigger safety 51 held in place via flexible ring 53. FIG.

For this shows figure 13 an actuating linkage 13 with the attached rotary slide device 7 at the upper end of the actuating linkage 13. This includes a key rod 42 which is connected to a coupling sleeve 15 at its lower end. Finally, the actuating linkage 13, more precisely the protective tube 16, has a closing ring 26 at its lower end 30. Anchorages 2 in the form of dowels 18, 19 can be clearly seen below the support plate 37.

figure 14 shows the actuating linkage 13 with the coupling sleeve 15 for connection to the mounting set and the closing ring 26 at the lower end of the actuating linkage 13. The key rod is also designated 42.

figure 15 illustrates the lower end of the actuating linkage 13 in the form of the closing ring 26 with the vertical webs 63, 64 as a kind of tool for installing and/or removing the dowels 18 - 20. Below this are the upper end of the mounting set with the polygon 36 and the dowels 18, 19, 20 with threads 21, 22, 23 shown.

figure 16 then shows a variant for the dowel solution with the end cap 60, the flange 56 and the receptacles 27, 28 for the dowels 18, 19, 20.

Good to see are then in figure 17 next to the guide pins 54, 55, the receptacles 27, 28, 29 in the ring 38 for the dowels 18, 19, 20 with threads 21, 22, 23 before they assume their position in which they develop the wedge effect.

Different then in figure 18 , where the dowels 18, 19, 20 are in their working position. Here, too, the ring 38/flange 56 includes receptacles 27, 28, 29 for the fastening means 18, 19, 20 and guide pins are designated 54 and 55,

the Figures 19 and 20 show a dirt cap 24 to protect the torsional interface between the ground anchor and the mobile rotating device. The dirt cap 24 is placed on the mounting set 1 before the street cap 43 is installed. For this purpose, the dirt cap 24 is designed to correspond to the upper end of the mounting set 1 . Two wings 57, 58 also make it easier to handle the dirt cap 24.

A support plate 67 in the form of an adapter is then the central object of figure 21 . Thanks to their profile 41, these specially shaped support plates 67, which may have to be concreted in, are particularly well suited for absorbing the counter-torque. With 68 the pin is still called. Below the closing ring 26 there is a keyhole profile that is concealed here.

The tool for this is an actuating linkage 13 with a rotary device 7 and pins 69 , 70 which correspond to the profile 68 of the support plate 67 .
