Abstract
Description
[0001] The invention relates to an installation kit for operating fittings running in the ground for connecting the fittings to pipelines, with a rod system which can be operated via a mobile rotating device and is surrounded by a sleeve pipe, with an anchoring in the surrounding ground which counteracts the rotation of the installation kit, the anchoring being integrated into an outer pipe surrounding the sleeve pipe.
[0002] The invention also relates to an installation kit for operating fittings running in the ground for connecting the fittings to pipelines, with a rod surrounded by a sleeve pipe and operable via a mobile rotating device.
[0003] When developing residential and industrial areas, fresh water pipes, drainage lines, and other pipes are laid in the road substructure. In some cases, the connections to the consumers are only established after the installation, which is why installation kits are provided at regular intervals. These enable the connection to the consumers or can be used to shut down or open the respective lines in sections. DE 295 16 158 is cited as an example. The use of mobile rotary or valve rotating devices is well known. The mobile rotary device is attached to the installation kit and the device is switched on. On long booms, waterworks workers must apply physical force to counteract the torque required to operate the valves, which can naturally lead to significant impairments.DE 10 2006 015 325 discloses a device for operating valves installed underground. A torsion-proof mount is provided at the operating point, comprising at least one portable and at least one stationary part. The torsion-proof mount absorbs the reaction torque that occurs and transmits it to the surrounding soil. However, with this solution, the anti-twist device in the form of a support plate must be installed with the surface cap. In practice, this means that either the torsion-proof support plate is installed during new construction, or the existing surface cap and support plate are removed and reinstalled with the torsion-proof support plate. This damages the road surface, which can potentially result in frost damage, subsidence, and other adverse effects.DE 20 2006 006 581 discloses an installation kit comprising pivot bearings formed by half-shells through which an actuator rod extends and which are rotatably mounted in a bearing bead on the front end of the link sleeve. GB 1 281 982 relates, among other things, to a laterally flanged pipe intended to serve as an anchor in the ground to prevent rotation of the outer pipe. WO 2017 / 161267 shows an installation kit for operating underground fittings for connecting to pipelines with a rod assembly operated via a mobile rotating device, and with the disadvantages described above.
[0004] The object of the present invention is to provide an installation kit for operating fittings running in the ground for connecting the fittings to pipelines, which is characterized by improved absorption of the reaction torque and a simple and safe design.
[0005] According to a first embodiment of the invention, this object is achieved by an anchoring mechanism in the surrounding soil that counteracts the rotation of the installation kit, wherein the anchoring mechanism is integrated into an outer tube surrounding the sleeve tube. According to the invention, the anchoring mechanism has at least one fold-out wedge for anchoring the installation kit in the soil. This wedge or wedges are folded out from their position adjacent to the outer tube, allowing the wedges to be driven into the ground at a suitable location, which provides the installation kit with additional options for adapting to the on-site conditions.
[0006] The subject of the invention is therefore, in particular, an anchoring in the ground on the side of the installation kit and thus a device that enables the waterworks operator to activate it "force-free" and to transmit the countertorque to the valve actuation torque into the ground via the installation kit and, if necessary, other components. The outer pipe, designed as a ground anchor, remains securely anchored in the ground and installed there. By integrating the anchoring into the outer pipe surrounding the sleeve pipe or as a component thereof, a special outer pipe is created that also surrounds the sleeve pipe and has an irregular contour, allowing the aforementioned anchoring to form. This solution can be easily installed into an existing support plate and street cap.
[0007] According to a second variant, the task is solved by an anchorage in the form of at least one dowel driven into the ground that counteracts the rotation of the installation kit.
[0008] This involves a technically less demanding solution using anchors driven into the ground. This means that the anchoring includes at least one anchor for anchoring the installation kit in the ground.
[0009] This solution proves particularly advantageous and relatively easy to implement when using multiple, evenly spaced anchors. Additionally, the anchor is designed to have a thread to further facilitate driving it into the ground.
[0010] Preferably, at least one cross-sectional extension in the outer tube serves as a further anchoring element. The outer tube therefore does not have a classic round contour, but rather at least one cross-sectional extension, which then protrudes outward, forming a wedge that counteracts rotation when installed.
[0011] In this sense, the proposal that the cross-sectional expansion is wedge-shaped is also understood in order to create this uneven contour, which then contributes to creating an optimal anchoring of the installation kit in the surrounding soil.
[0012] In order to ensure even distribution of forces, the outer tube is designed to include several cross-sectional extensions positioned at equal distances from one another.
[0013] An advantageous embodiment of the invention provides that the outer tube extends approximately over the upper third to the upper half of the installation kit and thereby encompasses the sleeve tube.
[0014] To implement the aforementioned wedge effect, the invention provides that the outer tube has an outer contour that allows a torsion-resistant connection to a portable actuating device. The inner contours of the protective tube of the actuating rod preferably correspond to the outer contours of the outer tube.
[0015] In this context, a supplementary embodiment of the invention provides that the installation spindle is equipped with an actuating rod that can be attached to the installation spindle, allowing the installation spindle to be operated from the operator's station. To this end, the actuating rod is attached to the installation spindle, and when the valve rotating device is switched on, a connection is formed that is secured against rotation, allowing the countertorque to the valve actuation torque to be transmitted into the ground. Instead of an installation spindle and an actuating rod, one could also speak of a two-part installation spindle, with a lower and upper part that are connected in the area of the surface cap.
[0016] It is intended that the actuating rod is surrounded by a torque-transmitting protective tube, which has a closing ring at its lower end, which has a torsion-resistant, form-fitting inner contour corresponding to the outer tube and its outer contour.
[0017] According to a further advantageous embodiment of the invention, the actuating rod 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 waterworks workers.
[0018] As far as the invention is concerned, the installation kit and the actuating rod are connected via a polygon or coupling sleeve. The polygon is located at the upper end of the installation kit, and the coupling sleeve corresponds to the lower end of the actuating rod. The latter, in turn, is surrounded by a sleeve tube and terminates at the lower end with a cap.
[0019] According to the invention, it is further provided that the upper end of the actuating rod serves to connect a mobile rotating device.
[0020] A preferred embodiment of the invention provides that a centering device is provided between the outer pipe and the edge cap of the installation kit, so that the outer pipe and installation kit are automatically positioned centered to one another.
[0021] Specifically, this involves the outer tube having an inward-facing, beveled collar at its upper end. The collar further tapers inward, so that the collar and bevel correspond to the edge cap, creating a snap-in connection, at least in the broadest sense.
[0022] The outer tube can be securely connected to the installation kit using a fastener, preferably one or more screws. The screw penetrates a recess provided in the collar of the outer tube and / or the hub cap.
[0023] A trigger safety device is also proposed. This is most conveniently located between the outer tube and the end ring at the lower end of the actuating rod. This means that a trigger safety device is provided between the outer tube and an end ring.
[0024] A preferred embodiment provides for the trigger safety device to comprise a pin that is held in position by a surrounding ring. This relatively small pin is pressed into position by a surrounding, flexible ring and engages a groove on the ground anchor.
[0025] According to the second variant of the invention, the problem is solved by an anchoring in the form of at least one dowel driven into the ground which counteracts the rotation of the installation set.
[0026] For easy handling of the dowels, it is also intended that the dowels are assigned together to an end cap that is to be connected to the end ring in order to realize the torsion-resistant connection.
[0027] In order to optimise the connection between the end cap and the dowels, the end cap is designed to have receptacles for the dowels.
[0028] To simplify the insertion of the dowels into the ground, the end ring of the actuating rod is provided with webs aligned parallel to the dowels.
[0029] In addition, it is intended that the webs are designed and arranged to correspond to the dowels.
[0030] The invention is particularly notable for creating an installation kit for operating fittings running underground for connecting to pipelines, which operates in a way that is gentle on the waterworks workers. In addition to a sleeve pipe, the rods of the installation kit also surround an outer pipe on the outside. In a first variant of the invention, this outer pipe has the task of exerting a wedge effect on the installation kit in the ground. For this purpose, the outer pipe is driven into the ground. However, since it does not have a classic round cross-section, but rather an extension, this outer pipe is anchored in the ground. In addition to the cross-sectional extension in a type of bulge, a solution is also possible in which one or more wedges can be folded out to then anchor it in the ground.The invention also relates to an actuating rod that can be attached to the installation kit by means of a polygon / coupling sleeve connection.
[0031] An alternative embodiment of the invention provides that one or more fastening means in the form of dowels, preferably provided with a thread, are used to anchor the fitting in the ground.
[0032] Further details and advantages of the subject matter of the invention will become apparent from the following description of the accompanying drawings, which illustrate a preferred embodiment with the necessary details and individual parts. They show: Figure 1: an installation kit with outer tube in installed condition, Figure 2: an installation kit with attached operating rod, Figure 3: an operating rod, Figure 4: an outer tube with dowel, Figure 5: an installation kit with dowel effect, Figure 6: a variant of Figure 4, Figure 7 an outer tube with fold-out wedges, Figure 8 a variant of Figure 7 , Figure 9 a centering between the edge cap and the outer tube, Figure 10 a centering between the edge cap and the outer tube with fastening means, Figure 11 a trigger safety device, Figure 12 the trigger safety device from a different perspective, Figure 13 an installation set with attached actuating rod with dowel anchoring, Figure 14 the lower end of an actuating rod, Figure 15 the installation set when using the actuating rod, Figure 16 an end ring with dowels and guide pins, Figure 17 dowels and guide pins, Figure 18 a variant of Figure 16 Figure 19 a dirt cap before assembly, Figure 20 a dirt cap after assembly, Figure 21 a fixing disc and Figure 22 an actuating rod with pins
[0033] Figure 1shows an installation kit 1 in its installed state. The installation kit 1 has a sleeve pipe 3 surrounding the rod assembly (not visible here), which terminates at the bottom with a bell adapter 35 and conceals the connection between the valve 5 and the pipeline 6 by means of a coupling sleeve. In the upper area of the installation kit 1, the anchoring 2, designed as an outer pipe 4, can be seen below the support plate 37. The outer pipe 4 has an irregular, wedge-shaped cross-section for the purpose of optimal anchoring of the installation kit 1 or outer pipe 4 in the surrounding soil. At its upper end 39, the installation kit 1 terminates in the surface cap 40.
[0034] In Figure 2The installation kit 1 with the attached actuating rod 13 and protective tube 16 is shown. A mobile rotating device 7 can be seen at the upper end 17 of the actuating rod 13. The valve rotating device 7 is attached to the assembly consisting of the installation kit 1 and actuating rod 13, so that the waterworks worker can now switch on this device 7 "force-free," whereupon the counter-torque to the valve actuation torque is introduced into the ground.
[0035] This shows Figure 3 an actuating rod 13 with the rotary valve device 7 mounted on the upper end 17 of the actuating rod 13. This comprises a key rod 42, which is connected at its lower end to a coupling sleeve 15. Finally, the actuating rod 13, or more precisely, its protective tube 16, has a closure ring 26 at its lower end 30. The closure ring serves to provide a torsion-resistant connection to the outer tube 4.
[0036] In Figure 4An outer tube 4 or adapter is shown. The outer tube 4 comprises an upper end ring 60 with the receptacles 61, 62 and, below it, the actual anchoring 2 in the form of wings 31, 32 as a cross-sectional extension 8, which grip the ground.
[0037] A variation of this shows Figure 5 , here in the form of an installation kit 1 with a bell adapter 35 and a comparatively long outer tube 4 with a plurality of vanes as cross-sectional extensions 8 in the area of the outer contour 33, of which only two are provided here as examples with the reference numerals 31 and 32. 36 also designates the polygon for attaching the actuating rod 13.
[0038] 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.
[0039] Another geometry for an outer tube / adapter 4 shows Figure 6with the wings 31, 32 for anchoring the outer tube 4. The latter has receptacles 61, 62 on its end ring 60 at the upper end for the purpose of connecting the actuating rod and the outer tube 4.
[0040] This shows Figure 7 an outer tube / adapter 4 with fold-out wedges 9 - 11 to improve the wedge effect, whereby variants of a folding mechanism are naturally practical.
[0041] In Figure 8 An outer tube / adapter 4 is again shown. For easier assembly, these can consist of two halves that can be screwed together to form one component.
[0042] Shown in Figure 9then the centering 46 between outer tube 4 and edge cap 45. Attention is drawn to the bevel 49, which corresponds to the inward-facing collar 47 at the upper end 48 of outer tube 4. It is clearly visible how automatic centering between outer tube 4 and edge cap 45 must occur during assembly.
[0043] A fixation between the outer tube 4, more precisely the collar 47 and the edge cap 45 then shows Figure 10 with special reference to the fastening means 50 in the form of a screw, which here corresponds to a receptacle 65 in the centering 47.
[0044] This shows Figure 11 The trigger safety 51 in the form of the pin 52, which is held in position by a flexible ring 53. The pin 62 engages the centering 47 or any other conceivable component with a corresponding receptacle.
[0045] Figure 12illustrates the trigger safety 51, which is held in position by the flexible ring 53.
[0046] This shows Figure 13 an actuating rod 13 with the rotary slide device 7 mounted at the upper end of the actuating rod 13. This comprises a key rod 42, which is connected at its lower end to a coupling sleeve 15. Finally, the actuating rod 13, or more precisely the protective tube 16, has a closing ring 26 at its lower end 30. Anchors 2 in the form of dowels 18, 19 are clearly visible below the support plate 37.
[0047] Figure 14 shows the operating rod 13 with the coupling sleeve 15 for connection to the installation kit and the end ring 26 at the lower end of the operating rod 13. 42 also designates the key rod.
[0048] Figure 15illustrates the lower end of the actuating rod 13 in the form of the end ring 26 with the vertical webs 63, 64 as tools for assembling and / or disassembling the dowels 18 - 20. Below this, the upper end of the installation set with the polygon 36 as well as the dowels 18, 19, 20 with thread 21, 22, 23 are shown.
[0049] Figure 16 then shows a variant for the dowel solution with the end cap 60, the flange 56 and the holders 27, 28 for the dowels 18, 19, 20.
[0050] Clearly visible are then 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 thread 21, 22, 23, before they take up their position in which they develop the wedge effect.
[0051] Different then in Figure 18where the dowels 18, 19, 20 are in their working position. Here, too, the ring 38 / flange 56 includes receptacles 27, 28, 29 for the fasteners 18, 19, 20, and 54 and 55 are guide pins.
[0052] The Figures 19 and 20 show a dirt cap 24 for protecting the torsional interface between the ground anchor and the mobile rotating device. The dirt cap 24 is placed on the installation kit 1 before the surface box 43 is installed. For this purpose, the dirt cap 24 is designed to correspond to the upper end of the installation kit 1. Two wings 57, 58 further facilitate the handling of the dirt cap 24.
[0053] A support plate 67 in the form of an adapter is then the central object of Figure 21These specially shaped support plates 67, which can be embedded in concrete if necessary, are particularly well suited for absorbing counter-torque thanks to their profile 41. The pin is also designated 68. A keyhole profile, concealed here, is located below the end ring 26.
[0054] The tool for this purpose is an actuating rod 13 with a rotating device 7 and pins 69, 70, which correspond to the profile 68 of the support plate 67.
