Description

The invention relates to a method for erecting a component and a corresponding erecting device.

To erect large and heavy components, for example a supporting arch of a steel bridge or a pile of a wind turbine, cranes have been used so far. However, the use of cranes is expensive and requires a considerable amount of space next to the component to be erected.

DE 35 21 212 A1 describes a method and an apparatus for erecting housing panels. The device comprises an abutment, a pressure bearing, a clasp, an erecting column and a lifting unit, which climbs up on the erecting column by pneumatically or hydraulically or mechanically generated friction.

From the DE 25 10 083 B2 a climbing lifting device with two climbing sections is known which can be locked to a climbing column via double-acting ratchet lever sets.

From the U.S. 5,368,125 A a device for lifting a scaffold platform is known with double-acting hydraulic cylinders.

The U.S. 5,579,865 A describes a modular gantry assembly with a platform that can be continuously moved up and down using multiple hydraulic cylinders.

The invention is based on the object of specifying a method and a device for erecting a component which enable a component to be erected in a space-saving and economical manner.

The object is achieved according to the invention by a method with the features of claim 1 and a device with the features of claim 4. Preferred embodiments of the invention are specified in the respective dependent claims.

In the method according to the invention, it is provided that a base of an erecting device is anchored to a base, the component to be moved is articulated to a working slide of the erecting device, which is mounted linearly displaceably on a guide rail mounted on the base, for performing a first erecting step of Working slide is moved by means of a feed device relative to an abutment slide which is linearly displaceably mounted and locked on the guide rail, the work slide is locked on the guide rail, the support slide is unlocked and the work slide is followed, and the support slide is locked on the guide rail and the work slide is unlocked so that a further erecting step can be carried out.

The erecting device according to the invention comprises a guide rail which can be pivotably mounted on a base, a work slide mounted on the guide rail so as to be linearly displaceable, an abutment slide mounted on the guide rail so as to be linearly displaceable, and a feed device for moving the work slide and the support slide relative to one another. The work slide has a connection adapter to which the component to be moved can be connected, and the work slide and the abutment slide each have locking devices with which the work slide or the abutment slide can be fixed to the guide rail.

A basic idea of the invention can be seen in erecting the component along a rigid guide bar, the erection taking place discontinuously in several successive erecting steps in which the working slide moves up the guide bar by a defined amount. The working slide is supported on the abutment slide, which is locked or arrested with respect to the guide rail during an erecting step.

After an erecting step has taken place, the locking of the abutment slide is released and the abutment slide is moved back to the work slide so that in a further lifting process the work slide can again move up along the guide rail. The component is erected step by step by alternately moving the work slide and the abutment slide along the guide rail. The work carriage and abutment carriage climb up along the guide rail.

The component, for example a supporting arch of a steel bridge or a pile of a wind power plant, is pushed upwards by the erecting device and not, as is known in the prior art, pulled by means of a rope. For this purpose, the erecting device is anchored on the one hand to a base and on the other hand connected to the component in such a way that compressive forces can be transmitted.

In terms of the method, it is provided in particular that the work steps mentioned are carried out in the order given.

Another basic idea of the invention consists in the pivotable mounting of the guide rail on the base. This makes it possible for the guide rail to rotate relative to the base during the erecting process, in particular during an erecting step of the work carriage, and to be able to erect together with the component.

For the pivotable mounting relative to the base, the guide rail preferably comprises a bearing eye and / or a bearing pin, by means of which at least part of a swivel joint is formed. The bearing eye can also be referred to as an eye connection.

As part of the erecting device, the base can also be referred to as a foot, in particular as a swivel foot. The foot can be anchored to the base surface, for example screwed and / or welded. After the component has been erected, the base is preferably detached from the base surface and removed so that it is available for a further erection process. Fastening devices, for example screws, are provided for anchoring or fastening the base to the base surface. The base preferably comprises a base plate for placing on the base of the environment.

Alternatively, the base can also be provided as a component of the surroundings directly on the base area, for example in the form of a bearing arranged there.

The base preferably comprises a mating connection for the eye connection of the guide rail, in particular at least one bearing eye and / or at least one bearing bolt. A swivel joint is formed by the eye connection of the guide rail and the mating connection of the base.

To connect the component to the erecting device, it is preferred that a connection element, for example a connection plate with a connection eye, be attached to the component, which connection element is pivotably connected to a connection adapter of the work carriage. The connection adapter can, for example, comprise a connection bolt which is inserted into the connection eye of the component and thus provides a pivotable connection between the working slide and the component that can be subjected to pressure.

A connecting bolt of the erecting device is preferably inserted into a connecting eye of the component and then mounted on an adapter base body of the work carriage. For this purpose, the connecting bolt is first detached from the adapter base body of the work slide, connected to the connection eye of the component to form a swivel joint and then mounted again on the adapter base body of the work slide. This enables the component to be securely and quickly fastened to the working slide, since the process of inserting the connecting bolt into the connecting eye, which requires particularly great precision, takes place away from the rest of the erecting device.

Furthermore, it is according to the invention that the working slide is moved relative to the abutment slide by means of a first feed cylinder and that the abutment slide is moved after the work slide by means of a second feed cylinder. The particularly different feed cylinders enable targeted adaptation to the respective requirements. The first feed cylinder is a powerful feed cylinder and the second feed cylinder is a less powerful, but possibly faster feed cylinder. It is also advantageous that the first feed cylinder is a one-sided and the second feed cylinder is a double-sided feed cylinder. The retraction of the first, one-sided working feed cylinder can take place by actuating the second feed cylinder when following the abutment slide.

The work slide and / or the abutment slide are preferably locked by means of locking bolts which engage in locking holes.

In terms of the device, it is preferred that the connection adapter comprises a connection bolt to which a connection eye of the component to be moved can be connected. A swivel joint is formed by the connecting bolt and the connecting eye.

An easy and quick connection of the component to the erecting device can be achieved in that the connection bolt is mounted on an adapter base body of the connection adapter so as to be detachable and fixable again. The connection bolt can be inserted into the connection eye of the component independently of the adapter base body to form the swivel joint and then be supported on the adapter base body.

In this context, it is particularly preferred that the connection adapter has an adapter foot connected to a base body of the work slide and an adapter head releasably attached to the adapter foot, the connecting bolt being arranged releasably and re-fixable between the adapter foot and the adapter head. The connection bolt can be removed by moving the adapter base and adapter head apart and by moving the adapter foot and adapter head together again on the adapter body. The connecting bolt is preferably arranged in a fork-shaped receptacle between the adapter foot and the adapter head.

For moving the work slide and the abutment slide along the guide rail, a hydraulic work cylinder is preferably provided as the feed cylinder. To operate the hydraulic cylinder, the erecting device comprises a hydraulic unit.

An effective mode of operation of the erecting device can be provided in that at least two different feed cylinders are provided. The feed device has at least one double-acting feed cylinder and one single-acting feed cylinder. The single-acting feed cylinder is used to move the working slide and the double-acting feed cylinder is used to move the abutment slide. Since the working stroke, that is to say the movement of the working slide, requires considerably greater forces, the corresponding feed cylinder is dimensioned larger than the feed cylinder for moving the abutment slide. The feed or hydraulic cylinders can also be referred to as hydraulic presses.

According to the invention, it is preferred that at least two guide bars are provided along which the guide carriage and the abutment carriage are guided. The guide bars are preferably arranged parallel to one another and next to one another. The at least two guide bars enable two-lane or multi-lane operation of the carriages, so that the carriages can be guided particularly safely, in particular protected against tilting. Furthermore, it is preferred that at least one first receiving area for a feed cylinder is provided between the guide bars and at least one second receiving area for a feed cylinder is provided on the side of one of the guide bars. The at least two receiving areas for one feed cylinder of the feed device each ensure a flexible adaptation option to the specific application conditions of the erecting device. The erecting device can optionally be equipped with one or more feed cylinders, the feed cylinders being able to be arranged either between the guide bars, to the side of the guide bars or both between and to the side of the guide bars.

In the case of two-track or multi-track operation of the erecting device, it is particularly preferred that a connection area of the connection adapter, in particular a connection bolt, is arranged centrally between two guide rails. This enables a uniform introduction of the weight of the component to be erected into the erecting device. The connecting bolt is preferably arranged in the plane of the guide bars, with a longitudinal axis of the connecting bolt extending transversely to the longitudinal axis of the guide bars.

An adjustment of the erecting device to different conditions of use can be achieved according to the invention in that the guide bars have a coupling device which enables the guide bars to be coupled at their longitudinal ends. The guide bars can thus be arranged coaxially to one another for single-track operation. Correspondingly, the working slide and the abutment slide can be converted for single-track operation, in particular by relocating their guide profiles into a central area. This makes it possible, in a simple manner, to double the travel path of the carriages.

To guide the slide, the guide rail preferably has a guide strip on its front and / or rear side, which is in engagement with a guide profile of the work slide and / or the abutment slide. The guide bar is preferably applied to an in particular tubular base body of the guide rail and extends essentially along the entire length of the base body. A front or rear side of the guide bar is to be understood in particular as that side in the direction of which the guide bar is moved when pivoting about the base.

The locking devices each preferably comprise at least one locking bolt which can be brought into engagement with a locking hole. The guide bar of the guide rail preferably comprises several locking holes which are arranged in a constant grid. The locking bolts are preferably mounted on the working carriage and on the abutment carriage, in particular in the area of the guide profile of the working carriage or the abutment carriage. A lifting cylinder for moving the locking bolts is preferably assigned to each of the locking bolts.
