Definitions

  • the present innovation relates to a device for introducing transport anchors into a casting mold for concrete parts, preferably into a casting mold for concrete pipes.
  • the weight of concrete parts is often so great that it can only be laid using a hoist. This applies particularly to concrete pipes laid in the ground.
  • at least one transport anchor must be provided on the outer sides, but they must not protrude from the outer surfaces, otherwise there is a considerable risk of breakage when transporting the parts.
  • Concrete parts are manufactured in a mold corresponding to their respective shape, which is referred to in the relevant branch as formwork.
  • the transport anchors are before pouring the liquid concrete into the Insert the casting mold in the correct position.
  • the present innovation is based on the object of developing a device of the type mentioned which, while increasing the performance of a machine for producing concrete parts, operates largely automatically and reliably so that the target position of the transport anchor to be poured in is exactly maintained.
  • a magazine for holding the transport anchors to be introduced in which a plurality of transport anchors with their longitudinal axes lying parallel to one another can be stored, an ejection device which can be moved transversely to the longitudinal axis of each transport anchor in two end positions for transferring one transport anchor to each Transport anchor gripping head holding, holding and attached to a slidable in the direction of the longitudinal axis of the transport gripper, with means the transport anchor can be inserted into the mold with its free end. It is now possible to have a larger number of transport anchors in the magazine for processing. Depending on the performance of the machine producing the concrete parts, it has to be replenished at certain intervals.
  • the operating personnel do not need to take any measures to insert the transport anchors into the casting mold, since the device works automatically. It is only necessary to ensure that the magazine is refilled before it is completely emptied.
  • the ejection device which can be moved transversely to the longitudinal axis of the respective transport anchor, ensures reliable transfer to the grippers that bring the transport anchor into the casting mold, since the transport anchor offers a large contact surface. Since the respective transport anchor is taken over by a gripper, not only a safe transfer is guaranteed, but also a correct insertion into the mold. Since the gripper is out. which is attached to a sliding carriage, the control can be designed so that the gripper only releases the transport anchor after the mold has been filled.
  • the gripper can also hold the transport anchor during the hardening time of the filled concrete. Deviations from the target position are therefore eliminated. Since the introduction of the transport anchors now takes place automatically, apart from filling the magazine, the performance of a machine producing concrete parts is increased by using the device according to the innovation.
  • the magazine is designed as a vertical magazine, in which the transport anchors can be inserted from above and lie one above the other with their longitudinal axes in a vertical plane, and in that the ejection device is arranged in the lower region of the magazine and can be moved in a horizontal plane.
  • Such an arrangement not only provides a functionally reliable and clear construction, but also allows the magazine to be filled from its upper side, so that this can be done independently of removal, since the lower transport anchor is pulled off by the ejection device.
  • the ejection device in an operationally reliable mode of operation is provided if the ejection device is designed as a slide which can be driven by a piston-cylinder unit and which has at its free end a receptacle shell which can be pivoted about a horizontal axis and is open towards the magazine each has a transport anchor.
  • the gripper becomes particularly simple if it is formed from two jaws which can be pivoted in opposite directions about a common horizontal axis. It is particularly advantageous that the jaws each have a recess corresponding to the head shape of the transport anchor on the mutually facing inner surfaces, the head end of the transport anchor being in the hollow space formed by the recesses when the jaws are closed. With such a design, the transport anchor is transported and held in a form-fitting manner, so that it is practically impossible to move the set position.
  • the gripper in the closed state of its jaws is on the front, the free end of the lifting anchor facing side is designed in the manner of a spherical cap, since it is then possible to achieve the necessary recess through the jaws on the outside of the concrete part.
  • the slide has to be moved so far in the direction of the casting mold that the part of the gripper in the shape of a caliber lies within the casting mold.
  • the device shown in Fig. 1 consists essentially of a vertical magazine 1, in which a plurality of transport anchors 2 are stored one above the other in a manner described in more detail, an ejection device 3 movable transversely to the longitudinal axis of the transport anchor and one in the direction of the longitudinal axis of the transport anchor 2 movable carriage 4, which carries an openable and closable gripper 5 at the end facing the vertical magazine 1.
  • Each transport anchor 2 is provided on its two end faces with a shoulder which is larger in diameter, as shown in FIGS. 2, 3 and 6 in particular.
  • the approach lying within the concrete part, not shown, is larger than the approach gripped by the gripper 6 when it is introduced into the casting mold.
  • the magazine 1 has two guides 6, 7 running in the vertical direction, which are arranged at a distance and in alignment with one another.
  • Each guide 6, 7 is formed from two guide rails 8, 9 arranged at a distance from one another.
  • the guide rails 8, 9 run parallel to one another and are firmly connected to one another via spacer bolts 10.
  • the guides 6, 7 can be seen in the sense of a T-shaped guide. Strength in particular from F. 2 and 3 can be seen, the transport anchors 2 stored in the vertical magazine 1 protrude forward, that is, in the direction of the cutting 4.
  • the vertical dimension Magazine provided with two roller chains 11, 12 running next to one another in the vertical direction, each of which is guided over two chain wheels 13, 14 arranged on a shaft in the upper and lower region of the vertical magazine 1.
  • the upper sprockets 13 form the drive sprockets, which are driven by a gear motor 16 via a further chain 15 and a sprocket arranged on the same shaft.
  • the geared motor 16 is connected in such a way that the strands of the roller chains 11, 12 facing / lying towards the transport anchors 2 are moved from top to bottom.
  • the ejection device 3 consists of a slide 17, which is attached to the piston rod 18 of a stationary hydraulic cylinder 19.
  • the slide 17 is guided in a guide 20 in a manner not explained in detail.
  • an upwardly open receiving shell 21 is pivotally mounted on the slide 17.
  • the pivot axis is designated 22.
  • a return spring 23 is articulated above the pivot axis 22 on the receiving shell 21, the opposite end of which is articulated on the slide 17 above the piston rod 18.
  • the gripper 5 consists of two jaws 24, 25 which can be pivoted about a horizontal axis 26, the axis 26 lying opposite the jaw side, which in each case grips a transport anchor 2.
  • the jaws 24, 25 are designed as solid bodies and, in the closed state, describe approximately the shape of a hemisphere.
  • Each jaw 24, 25 is on the side opposite the axis 26 with one each Insert 27.28 provided, which is firmly inserted into corresponding recesses.
  • Each insert 27, 28 is provided with a recess 29, 30, which extend to the edge facing away from the axis 26, and in the closed state of the jaws 24, 25 form a hollow chamber corresponding to the head shape of the transport anchor 2.
  • the axis 26 is mounted with its two ends in a guide ring 31 in a rotationally fixed manner.
  • the guide ring 31 on its inner side in the region of the end face facing the cutouts 29, 30 is a guide for the outer surfaces of the blocks 24, 25. This part is therefore designed in an arc shape.
  • the guide ring 31 is worn white holding webs 32, 33 which are welded to the outside of the guide rings 31.
  • the holding rods 32, 33 are fixedly arranged on the carriage 4 in a manner not explained in detail.
  • the ends of the holding rods 32, 33 opposite the guide ring 31 are connected by means of a lug 34, so that the holding rods 32, 33 and the lug 34 form a U-shaped holder.
  • a piston-cylinder unit 35 On the side facing the gripper 2, a piston-cylinder unit 35, in the present exemplary embodiment a hydraulic cylinder, is fastened to the tab 34, the piston rod 36 of which can be extended in the direction of the gripper 2, and carries an actuating linkage 37, which faces with it lying end faces of the jaws 24, 25 is articulated.
  • the actuating linkage 37 consists of a bracket 38 fixedly attached to the piston rod 36 and two links 39, 40 arranged on the jaws 24, 25 so as to be rotatable.
  • FIG. 5 shows a partial section of a casting mold 41 which, in the present exemplary embodiment, is designed for the production of concrete pipes.
  • An opening 42 is provided in the outer wall into which a seal 43 attached to the mold 41 protrudes.
  • 6 shows that by moving the slide, the jaws 24, 25 protrude into the mold 41 to a predetermined extent. However, the jaws 24, 25 were previously closed by extending the piston rod 36 of the piston-cylinder unit 35.
  • the vertical magazine 1 To start up the device, the vertical magazine 1 must first be filled with transport anchors 2.
  • the transport anchor 2 lying at the bottom is received by the receiving shell 21 for introduction into the casting mold 41.
  • the piston rod 18 By acting on the piston of the hydraulic cylinder 19, the piston rod 18 is extended, as a result of which the transport anchor is aligned with the central longitudinal axis of the gripper 2. This position is shown in FIG. 3.
  • the jaws 24, 25 are still open, but are closed shortly thereafter by extending the piston rod 36 of the piston-cylinder unit 35.
  • the transport anchor 2 is then secure and held in place by the shape of the recesses 29,30.
  • the receiving shell 21 is pivoted so that the slide 17 can return to the starting position by reversing the hydraulic cylinder 19.
  • the return spring 23 causes the receiving shell 21 to pivot back.
  • the lower transport anchor 2 located in the vertical magazine 1 rests on the return spring 23, so that further slipping is not possible.
  • the carriage 4 and thus the gripper 5 and the transport anchor 2 located therein can be moved in the direction of the casting mold by a drive which is not explained in more detail.
  • the mold can then be poured out with concrete. Since the seal 43 closes on the outside side of the jaws 24, 25, no concrete can run out of the mold 41. Since the jaws 24, 25 also protrude into the casting mold 41, a recess is created in the concrete part in order to later attach a rope or a chain when laying.
  • the carriage 4 is moved so far that the lifting anchor 2 is flush with the outer surface of the concrete part, or protrudes only by a small amount in relation to the length.
  • the jaws 24, 25 can be opened by reversing the piston-cylinder unit 35, since the longitudinal axis of the horizontal axis 26 forms the center of curvature for the jaws 24, 25.
  • the carriage can be moved back to its starting position. The insertion process can then be started again.
  • the gear motor 16 is switched on in the vertical magazine 1 to prevent the transport anchor from tilting.
  • the roller chains 11, 12 rotate in the direction of the arrow A, and a tilted transport anchor 2 is also moved downward by frictional engagement.
