Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst, wobei weitere Ausgestaltungen der Erfindung den Ansprüchen 2 bis 14 entnommen werden können.The object is achieved by the features of claim 1, wherein further embodiments of the invention can be taken from claims 2 to 14.
Die Erfindung geht aus von einer Schieberkappenziehvorrichtung zum Ziehen einer in einem Schieberkappenrahmen aufgenommenen Schieberkappe mit einem sich in einem Bereich des Schieberkappenrahmens abstützbaren Grundgestell, mit einer in dem Grundgestell geführten Gewindespindel, die mit einer Dreheinrichtung drehbar ist, und mit einer mit der Gewindespindel koppelbaren Einhakeeinrichtung, die zum Einhaken in die Schieberkappe vorgesehen ist, wobei das Grundgestell einen Sockel und einen auf dem Sockel aufgesetzten Aufbau aufweist, wobei der Sockel des Grundgestells die Einhakeeinrichtung umgibt.The invention is based on a slide cap pulling device for pulling a slide cap accommodated in a slide cap frame with a base frame which can be supported in a region of the slide cap frame, with a threaded spindle guided in the base frame, which is rotatable with a rotating device, and with a hooking device which can be coupled to the threaded spindle, which is provided for hooking into the slide cap, wherein the base frame has a base and a patch on the base structure, wherein the base of the base frame surrounds the hooking device.
Dadurch, dass der Sockel des Grundgestells die Einhakeeinrichtung umgibt, kann die Schieberkappenziehvorrichtung besonders vorteilhaft kippsicher auf dem Boden aufgestellt werden. Zusätzlich kann das auf dem Boden aufgestellte Grundgestell der erfindungsgemäßen Schieberkappenziehvorrichtung eine über die Einhakeeinrichtung konzentrisch wirkende vertikale Kraft gleichmäßig aufnehmen und diese zum Herausziehen auf eine Schieberkappe bzw. eine Ventilkappe übertragen. Die Schieberkappe kann im herausgezogenen Zustand innerhalb des Grundgestells der Schieberkappenziehvorrichtung gehalten werden. Ein weiterer Vorteil des Grundgestells ist die große umlaufende Auflagefläche des Sockels, welche auf schonende Weise sowohl ein Herausziehen des Schieberkappenrahmens als auch eine Beschädigung des angrenzenden Straßenbelags verhindern kann. Im Gegensatz zu herkömmlichen Schieberkappenziehvorrichtungen kann die erfindungsgemäße Schieberkappenziehvorrichtung aus einer geringen Anzahl von Bauteilen hergestellt werden, die im Wesentlichen aus rechtwinkligen Profilen und aus Vierkanthölzern bestehen kann. In vorteilhafter Weise kann hierdurch eine einfache und kostengünstige Schieberkappenziehvorrichtung bereitgestellt werden, die auf Grund ihrer kompakten Größe besonders leicht, stabil und handlich ausgeführt werden kann.Due to the fact that the base of the base frame surrounds the hooking device, the slide cap pulling device can be set up on the ground in a particularly advantageous manner in a tilt-proof manner. In addition, the raised on the floor base of the Schieberkappenziehvorrichtung invention can take a concentric over the hooking device acting vertical force and this for pulling out on a slide cap or a valve cap transfer. The slide cap can be held in the withdrawn state within the base frame of the slide cap pulling device. Another advantage of the base frame is the large circumferential bearing surface of the base, which can gently prevent both a pulling out of the slide cap frame and damage to the adjacent road surface. In contrast to conventional Schieberkappenziehvorrichtungen the Schieberkappenziehvorrichtung invention can be made of a small number of components, which may consist essentially of rectangular profiles and Vierkattanölzern. Advantageously, this can be a simple and inexpensive Schieberkappenziehvorrichtung be provided, which can be made particularly lightweight, stable and handy due to their compact size.
In einer Ausgestaltung der Schieberkappenziehvorrichtung wird vorgeschlagen, dass der Sockel des Grundgestells mehreckig ausgeführt ist. Die mehreckige Ausgestaltung des Sockels der Schieberkappenziehvorrichtung ist aus statischen Gründen vorteilhaft. Die Schieberkappenziehvorrichtung weist hierdurch eine stabile Bauweise auf, so dass auf zusätzliche, statisch notwendige Verstrebungen verzichtet werden kann. Ferner ist die mehreckige Ausgestaltung des Sockels besonders vorteilhaft, da die Schieberkappenziehvorrichtung hierdurch einen größeren Raum einschließen kann, der auch für große Schieberkappen genutzt werden kann. Ferner kann die Schieberkappenziehvorrichtung sowohl besonders einfach, standfest und formstabil hergestellt als auch lagestabil aufgestellt werden. In vorteilhafter Weise kann ein mehreckig ausgeführter Sockel des Grundgestells besonders praktisch in einem Fahrzeug oder einem Raum gelagert werden.In one embodiment of the Schieberkappenziehvorrichtung it is proposed that the base of the base frame is made polygonal. The polygonal configuration of the base of the Schieberkappenziehvorrichtung is advantageous for static reasons. The Schieberkappenziehvorrichtung has thereby a stable construction, so that it can be dispensed with additional, statically necessary struts. Furthermore, the polygonal configuration of the base is particularly advantageous because the Schieberkappenziehvorrichtung can thereby include a larger space that can be used for large slide caps. Furthermore, the Schieberkappenziehvorrichtung can be both particularly simple, stable and dimensionally stable produced as well as positionally stable. Advantageously, a polygonal executed base of the base frame can be stored in a vehicle or a space particularly practical.
In einer Ausgestaltung der Schieberkappenziehvorrichtung wird vorgeschlagen, dass der Sockel des Grundgestells rund ausgeführt ist. Beispielsweise kann dies oval, elliptisch oder kreisrund erfolgen. Hierdurch kann eine formstabile und standfeste Schieberkappenziehvorrichtung hergestellt bzw. aufgestellt werden, deren Sockel je nach Ausführung mit einem konstanten Durchmesser oder mit unterschiedlichen Radien versehen und damit durch geringe Drehung optimal auf unterschiedliche Schieberkappen bzw. Ventilkappen besonders einfach angepasst werden kann. Der Innendurchmesser des Sockels des Grundgestells kann wunschgemäß auf eine Schieberkappen-Größe bzw. Ventilkappen-Größe eingestellt werden.In one embodiment of the Schieberkappenziehvorrichtung it is proposed that the base of the base frame is made round. For example, this can be oval, elliptical or circular. In this way, a dimensionally stable and stable Schieberkappenziehvorrichtung be prepared or set up, the base depending on the design provided with a constant diameter or with different radii and thus can be easily adapted by turning slightly on different slide caps or valve caps. The inner diameter of the base of the base frame can be adjusted as desired to a slider cap size or valve cap size.
Es wird vorgeschlagen, dass der Aufbau des Grundgestells pyramidenförmig ausgeführt ist. Dadurch ist in vorteilhafter Weise konstruktiv die Voraussetzung für eine optimale und gleichmäßige Belastbarkeit des Grundgestells der Schieberkappenziehvorrichtung gegeben, da eine übereinstimmende Lage der Mittelachse bzw. der Koaxialität der Einhakeeinrichtung definiert zum Einhängepunkt der Schieberkappen bzw. Ventilkappen gewährleistet werden kann.It is proposed that the structure of the base frame is pyramid-shaped. As a result, the prerequisite for optimal and uniform load capacity of the base frame of the Schieberkappenziehvorrichtung is given in an advantageous manner, since a coincident position of the central axis or the coaxiality of Einhakeeinrichtung defined for Einhängepunkt the slide caps or valve caps can be ensured.
In vorteilhafter Ausgestaltung der Erfindung ist der Aufbau zur Aufnahme einer Gewindebuchse vorgesehen, in welcher die Gewindespindel drehbar geführt ist. In vorteilhafter Weise kann hierdurch die Gewindebuchse in einer definierten Lage sicher und stabil mit dem Aufbau verbunden werden.In an advantageous embodiment of the invention, the structure for receiving a threaded bushing is provided, in which the threaded spindle is rotatably guided. Advantageously, this can be safely and stably connected to the structure in a defined position the threaded bushing.
Ein weiterer Vorteil der Erfindung ist, dass die Spitze des als Pyramide ausgeführten Aufbaus zur Aufnahme der Gewindebuchse vorgesehen ist. Hierdurch kann die über die Gewindespindel in den pyramidenförmigen Aufbau eingeleitete Kraft gleichmäßig auf das Grundgestell der Schieberkappenziehvorrichtung verteilt werden. In vorteilhafter Weise ist die Gewindebuchse einfach und preisgünstig in den Aufbau integrierbar.A further advantage of the invention is that the tip of the construction designed as a pyramid is provided for receiving the threaded bushing. As a result, the force introduced via the threaded spindle into the pyramidal structure can be distributed uniformly to the base frame of the slide cap pulling device. Advantageously, the threaded bushing is easy and inexpensive to integrate into the structure.
Es wird vorgeschlagen, dass die Gewindebuchse ein Trapezgewinde aufweist. In vorteilhafter Weise weist das Trapezgewinde im Gegensatz zum metrischen oder Whitworth-Gewinde dickere Gewindegänge und somit ein größeres Steigungsmaß auf. Dieses große Steigungsmaß der Gewindebuchse kann bei einer Drehbewegung der korrespondierenden Gewindespindel eine schnelle Höhenverstellung bewirken, wodurch eine Schieberkappe bzw. Ventilkappe schnell aus dem Schieberkappenrahmen herausgezogen werden kann. Da dicke Gewindegänge des Trapezgewindes größere axiale Kräfte als metrische oder Whitworth-Gewinde übertragen können, bevor sie durch Abscheren versagen, kann sichergestellt werden, dass festsitzende Schieberkappen bzw. Ventilkappen sicher aus dem Schieberkappenrahmen herausgezogen werden können.It is proposed that the threaded bushing has a trapezoidal thread. Advantageously, the trapezoidal thread, in contrast to the metric or Whitworth thread thicker threads and thus a larger pitch measurement. This large pitch of the threaded bushing can cause a quick height adjustment in a rotational movement of the corresponding threaded spindle, whereby a slide cap or valve cap can be quickly pulled out of the slide cap frame. Because thick threads of the trapezoidal thread can transmit greater axial forces than metric or Whitworth threads before failing by shearing, it can be ensured that tight fitting valve caps can be safely withdrawn from the valve body frame.
Ferner wird vorgeschlagen, dass die Gewindespindel an einem oberen Ende eine Vierkantaufnahme aufweist, die zur drehfesten Verbindung der Gewindespindel mit einer als Schieberschlüssel ausgeführten Dreheinrichtung vorgesehen ist. Ein wesentlicher Vorteil der Vierkantaufnahme der Schieberkappenziehvorrichtung besteht darin, dass die erfindungsgemäße Schieberkappenziehvorrichtung mit einem gängigen und handelsüblichen Schieberschlüssel bzw. Ventilschlüssel bedient werden kann, da die Vierkantaufnahme der Schieberkappenziehvorrichtung identisch ist mit der Vierkantaufnahme der unterhalb der Schieberkappen bzw. Ventilkappen befindlichen Schiebergestänge bei Wasserabsperrungen bzw. Hydrantenabsperrungen. Daher kann die erfindungsgemäße Schieberkappenziehvorrichtung im Gegensatz zu Schieberkappenziehvorrichtungen aus dem Stand der Technik lediglich mit einer Vierkantaufnahme, ohne eine Dreheinrichtung ausgeführt werden, da hierbei als Dreheinrichtung der gängige Schieberschlüssel bzw. Ventilschlüssel verwendet werden kann. Hierdurch kann die erfindungsgemäße Schieberkappenziehvorrichtung besonders wirtschaftlich hergestellt werden. Da das Bedienpersonal bei Kontrollarbeiten und/oder Reparaturarbeiten stets einen Schieberschlüssel bzw. Ventilschlüssel mit sich führt, kann bei der erfindungsgemäßen Schieberkappenziehvorrichtung eine eigenständige und aufwändige konstruktive Ausführung der Dreheinrichtung mit einer Handkurbel oder einem Drehrad an der Schieberkappenziehvorrichtung entfallen, wodurch die erfindungsgemäße Schieberkappenziehvorrichtung besonders bedienfreundlich in verschiedenen Größen ausgeführt werden kann. Neben einer wesentlichen Vereinfachung und einer technischen Verbesserung der erfindungsgemäßen Schieberkappenziehvorrichtung können somit die Herstellungskosten und die Montagekosten beträchtlich gesenkt werden, wodurch die erfindungsgemäße Schieberkappenziehvorrichtung besonders wirtschaftlich hergestellt werden kann.It is also proposed that the threaded spindle has a square socket at an upper end, which serves for the rotationally fixed connection of the threaded spindle is provided with a turning device designed as a slide key. An essential advantage of the square holder of Schieberkappenziehvorrichtung is that the Schieberkappenziehvorrichtung invention can be operated with a standard and commercially available spanner or valve key, since the square socket of the Schieberkappenziehvorrichtung is identical to the square recording of the located below the slide caps or valve caps slide rod in water barriers or hydrants barriers. Therefore, the Schieberkappenziehvorrichtung invention can be performed in contrast to Schieberkappenziehvorrichtungen from the prior art only with a square, without a rotating device, since this can be used as a rotating device of the common slide key or valve key. As a result, the Schieberkappenziehvorrichtung invention can be produced particularly economically. Since the operating personnel always performs a slide key or valve key during control work and / or repair work, a separate and complex structural design of the rotary device with a hand crank or a rotary wheel on the slide cap pulling device can be dispensed with, whereby the slide cap pulling device according to the invention is particularly user-friendly in different sizes can be executed. In addition to a substantial simplification and a technical improvement of the Schieberkappenziehvorrichtung invention thus the production costs and installation costs can be considerably reduced, whereby the Schieberkappenziehvorrichtung invention can be produced particularly economically.
In einer Ausgestaltung wird vorgeschlagen, dass die Einhakeeinrichtung als ein an einem unteren Ende der Gewindespindel aufschraubbarer Haken ausgeführt ist. Hierdurch kann eine über eine Drehbewegung in die Gewindespindel eingeleitete Kraft insbesondere spielfrei auf eine Schieberkappe übertragen werden. In vorteilhafter Weise kann der Haken besonders leicht in der üblicherweise genormten, mit einem Flacheisen versehenen Ausnehmung der Schieberkappe bzw. der Ventilkappe eingehakt werden, so dass ein besonders effektives Anheben der Schieberkappe bzw. der Ventilkappe erfolgen kann. Die als Haken ausgeführte Einhakeeinrichtung kann bei einem Zugvorgang eine sichere Verbindung gewährleisten.In one embodiment, it is proposed that the hooking device is designed as a hook which can be screwed onto a lower end of the threaded spindle. In this way, a force introduced via a rotational movement into the threaded spindle can be transmitted, in particular without play, to a slide cap.
