Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application of Industry-1- The present invention comprises at least two gripping jaws or clamping jaws movable toward each other in a pincer-like manner. This invention relates to a device for laying pavement stones of a type that can grasp a plurality of pavement stones located side by side, hold them, and place them in a predetermined place.

PRIOR TECHNOLOGY A pin-shaped device for laying pavement stones is already known, and this device is used to transport and place paving stones located at a distance of X7 to each other at a predetermined location. Ru.

Problems to be Solved by the Invention The known devices have problems in terms of functionality. Example 14: Me was transported from the factory using known equipment. If you grab the pavement stone layer on the o-let, lift it at the appropriate position, and transport it to the predetermined installation location, it will not be able to be removed.

Is the cause of this due to the transmission of the force of the gripping jaws to the pavement stones? Ij
If this is done incorrectly or inconveniently, the pavement stones may slip, the pavement stone or stones may slide down, or the pavement stone layer may curve upwards and shuffle. This difficulty generally results in the gripped paving stones falling or in an unsatisfactory paving condition. Therefore, known devices of this type do not allow fast, economical and troublesome work.

It is therefore an object of the present invention to improve a device of this type in order to avoid the drawbacks of the known devices and, in particular, to be able to grasp the entire layer of paving stones from a common cargo pallet without any problem and transport it to the laying site, and to lay it with a beautiful finish. It is about making things possible.

Means of the Invention for Solving the Problem A feature of the invention resides in that the gripping jaws are designed to be movable with respect to the paving stone or paving stone layer to be gripped.

In one embodiment of the invention, the gripper jaws are each arranged so as to be pivotable about at least one horizontal pivot axis. This results in a simple and stable structure.

'! '! j', t'1 According to the embodiment of claim No. 3, the gripping jaws are arranged in such a manner that the gripping jaws extend 14"J over at least the pavement stone layer, and each has a penetrating water shaft. It is pivotably supported in a vertical plane.

In accordance with the embodiment of claim 4, the gripping jaw is divided into four gripping jaws, each of which is arranged in particular on a horizontal pivot axis arranged coaxially with respect to one another. has been done.

According to an embodiment according to claim 5, the gripping jaws are powered. Regarding 6, the work is 1
A slight force exerted by the worker, for example by remote control from the control station I'' of a suitable civil engineering vehicle, may cause problems.
The same predetermined force is always applied to the gripping jaws. This force can optionally be controlled from a control stand.

According to the embodiment according to claim 6, the gripping jaws are driven by a piston-cylinder unit which is loaded by an approximately horizontal flat angle 1 above the paving stone layer to be gripped.

The cylinders of this piston-cylinder unit are connected to at least one angle lever, which angle levers are opposed to the respective gripping jaws on one side of the device, and the piston rods of the piston rings are likewise connected to one another. It is force-transmissively connected to the gripping jaws on the other side of the device via at least two angle levers. This angle lever extends approximately in a vertical plane.

According to the embodiment according to claim 7, a plurality of paving stone layers can be grasped simultaneously and placed one after the other on the installation site. This reduces wasted time in reciprocating transportation of the machines that load or unload the paving stones, and increases the efficiency of the laying operation.

According to the embodiment described in claim 8, the grasping and
On the surface where the jaw comes into contact with the pavement stones,
It is equipped with a wear insert consisting of y, go L2, 嬬ρ inpal chopstick person q-nh9-demand YudKsu≦skin l)-ρ21 tick. This cushions the grip on the pavement stones. Moreover, the force is introduced in a uniformly distributed manner.

Fat-' [according to the embodiment of claim 9, 1
``The device is configured to be adjustable in the width direction and/or length direction. In this way, pavement top layers of different sizes can be handled, transported and laid without problems.

'[! +'n According to the embodiment of claim 10, the above-mentioned adjustment is carried out continuously, for example by means of a piston-cylinder arrangement which is loaded alternately from both sides with a pressure medium, in particular oil.

According to a particularly advantageous embodiment of the invention, the device is attached to a rotary motor, which grips the device and thus rotates the jaws slightly about at least one vertical axis. In that case, the device and thus the gripping jaws are driven about a vertical axis of rotation by means of an electric or hydraulic or electrohydraulic rotary motor. Thereby, the gripping jaws are dynamically controlled into the correct rotational position when receiving and placing the paving stone, and this control can be carried out, for example, from a central control stand, for example an earth-moving machine, a crane or the like, or from another central control stand. This is done by the simple actuation of a switch, either from the outside or by manual control of a person standing near the device.

The arrangement described in the embodiment according to claim 12 is extremely compact. The rotary motor is integrated directly into the force transmission path and is arranged coaxially with respect to the load-bearing member.

The embodiment described in claim 13 allows work with particularly high sensitivity.

The embodiment according to claim 14 is structurally robust. This allows large weights to be grasped and transported. As a result, in the case of long gripping jaws, a plurality of piston cylinder units can be engaged with the gripping jaws over the length of the gripping jaws, and force can be uniformly introduced over the entire length of the gripping jaws by kneading, and the inclination of the gripping jaws can be reduced. Avoided.

The load-bearing member is generally a tube, a profiled tube, or a number of molded materials that can be cut into a tube.

In order to ensure a good introduction of forces, it is also possible to reinforce the pipes, moldings, etc. at the points where the stone/ring cone is supported via the intermediate part A'A.

Embodiment d of patent claim 15 is an advantageous embodiment.

The embodiment recited in claim 16 is effective for quickly carrying out repair work.

The reason for this is that the angle lever can be fixed on one axis and replaced as a structural unit.

The actual %i embodiment described in claim 17 is a highly practical embodiment. Ground to be paved near the equipment -
What is the most common problem when a device suspended from a load support member is suspended in the air? It is possible to pull, push, swivel and rotate the paving stone layer in 13 dimensions to a certain extent on the order of IJ meters to the installation site, after which the paving stone layer can be paved.

The embodiment described in claim no. +8'ffi allows the device to be gripped from all sides by means of a vertical grip. Moreover, hand injuries are avoided.

The embodiment according to claim 19 is a particularly advantageous embodiment. In this embodiment, the device, the gripping jaws and thereby the broken pavement stones, are movable in the horizontal direction even when the load-bearing member is at rest. This also allows the paving stones to be moved precisely on site.

Machines on which the equipment is suspended, such as excavators, cranes, etc., therefore do not have to operate with precision on the order of millimeters. Rather, after the device has largely been swiveled, a precise movement of the device takes place by means of a special configuration of the rolling bearing suspension bearing or support bearing. This also increases the radius of action. Even in situations where, for example, the jib of a crane cannot be swiveled any further without danger, the special configuration of the device according to the invention allows precise movements at right angles to the load-bearing member. With the provision of grips, it is possible to adapt the paving stone layer to the pavement at any desired point.3 This divine pressure support may consist of two plates spaced parallel to each other (d). One of the plates is provided with a through hole, through which the part IJ opposite to the gripping jaw is penetrated and engaged, and the part IJ is inserted upwardly.
It can be connected to the other plate on which it is placed. Rolling elements such as balls, rollers, rollers or wheels can be arranged between the two plates. Both plates may be arranged so as to be movable toward one another in a vertical plane, for example via rolling bearings.

Lateral movement can be limited by stops. The rolling elements can be housed in cages or other guides.

The embodiment according to claim 20 is a particularly advantageous embodiment. In this embodiment, at least one trolley is arranged by means of which the gripping jaws can be moved transversely with respect to the load-bearing member.

The embodiment according to claim 21 has a robust construction that takes into account the rough conditions of the work site. In this embodiment, two trolleys are arranged one above the other in two horizontal planes parallel to each other, so that their main direction of movement is horizontal, but both directions of movement are at right angles to each other. Rotating motor 1 grip and associated with this trolley allow sensitive adjustment of the power of the gripping jaws and the entire device, with a high degree of precision not possible by hand and with which complex pavement layers can be manipulated at extremely high speeds. becomes. According to experiments, the operating capacity of this embodiment is several times higher than that of a skilled worker.

Operation With the device according to the invention, the gripping jaws are automatically adjusted in accordance with the resultant force in such a way that the gripping force is optimally introduced into the pavement stone layer to be gripped. This eliminates falling of the pavement layer or bending or damage of the pavement layer. The pavement stone layer is for transportation,
It remains aligned to the same state as if it were located on the o-let. Moreover, according to the device of the invention, the I of the pavement layer
