Definitions

  • Actuators can transmit tensile and compressive forces, but they must be able to carry out a long stroke, so that there are long dimensions, which often impede the work in the area of the prescribed position.
  • Rail-bound equipment such as sledges, carriages and the like rigidly restrict the movement in one direction. The working height is also limited by the stroke of the frame used.
  • the invention has for its object to provide a device for positioning loads with which both compressive and tensile forces can be transmitted and which can be accommodated space-saving in the range of motion of the loads to be positioned after use.
  • a rod-shaped support element that is rigid in two planes is proposed, which can be assembled from individual elements during the positioning process.
  • both tensile and compressive forces can be transmitted to the load to be positioned.
  • the support element preferably consists of two elements, which are rigid in one plane and run in parallel. Spacers and connecting elements are arranged between these.
  • Commercially available link chains which are arranged in parallel and at a distance from one another, are particularly suitable for this.
  • One of the link chains serves as a feed chain into which a chain drive wheel engages.
  • the second chain is provided as a locking chain, the links of which engage in the connecting elements due to the movement of the chain drive wheel.
  • a support element is formed from individual parts, which shows an essentially double-T-shaped profile.
  • the locking chain can be of smaller dimensions than the feed chain.
  • a commercially available duplex chain is particularly suitable as the feed chain. You can wear the locking links in the middle of the chain sitting on the hinge pin.
  • the chains with their ends facing away from the load are supported in an articulated manner on a bearing that absorbs the longitudinal forces, while their opposite ends are attached to the housing of a chain drive that can be moved on the chains are.
  • a brake motor with a chain drive wheel and a chain drive housing which is provided with a chain guide, is particularly suitable as a chain drive.
  • the chain guide is firmly connected to the drive housing and comprises the chains joined together to form a fixed support, the chain guide extending in the longitudinal direction over the length of several chain links. This allows the engine torque to be effectively transmitted to the chain drive gear.
  • Flat connecting links of small wall thickness are suitable as connecting links, which at the same time keep the chains at their prescribed distance. They sit firmly on the bolts of the feed chain and show a groove at their free ends. With this groove, when the chains are joined to form a support unit, they rest on the hinge pins or on the roller sleeves of the locking chain sitting on them.
  • the locking links can replace the inner plates of the duplex chain used by their tab-shaped fastening parts in order to avoid excessive chain width.
  • the chain drive housing is preferably provided with an entry and exit channel for the locking chain.
  • the entry and exit channel shows guide profiles against which the locking chain when closing in the feed direction or when retracting the chain drive, i. H. when opening, starting and being guided.
  • a device is suitable for pendulum suspended loads to be positioned also pendulum suspended and the articulated support bearing of the chains is attached to the side of a support wall or to the strut of a support frame. Furthermore, the suspension of the chain drive can be connected to a lift cylinder with which the height of the load to be positioned can be adjusted. The height adjustment and the movement of the load in the horizontal direction can take place simultaneously. This version is particularly suitable for handling heavy tools on drilling rigs.
  • the support element formed according to the invention consists of a duplex chain 1 as a feed chain, a smaller locking chain 2 and connecting elements 3 which are fastened seated on the hinge pin 4 of the feed chain 1.
  • the connecting elements 3 are parallel to each other at the prescribed distance.
  • the connecting elements 3 with a groove 5 lie against the articulated bolts or against the roller sleeves of the locking chain arranged on the bolts.
  • the connecting elements therefore also act as locking elements for locking the locking chain.
  • the foot 6 of a connecting or locking member 3 has the shape of a chain link and can replace it.
  • the hinge pins engage in the same way as when attaching the link plates through openings 7.
  • a chain drive device 8 is arranged to be movable on the chains.
  • a chain guide 10 attaches to the housing 9 thereof, which extends in the longitudinal direction of the support element 11 assembled from the individual parts and thereby encompasses the feed chain on both sides in the manner of a clamp. This produces a positive connection which enables the torque to be transmitted from the drive motor 12 (FIG. 5) via a chain wheel 13 which engages in the feed chain.
  • the chain guide 10 thus simultaneously serves to absorb the counter moment.
  • the device designed according to the invention is provided for positioning hanging loads, for example an eccentric pipe wrench suspended from a derrick.
  • the chain drive device 8 is suspended via a support ring 14 on a steel cable 15 which starts from the top of the derrick.
  • the support cable 15 carries the load to be positioned below the chain drive device.
  • a height compensation for the load can be carried out via a lift cylinder 16.
  • the feed chain 1 and the locking chain 2 are screwed to the housing 17 of an articulated coupling.
  • the articulated coupling can be moved on all sides by an articulated ball 18, which is seated within the housing 17.
  • the ball 18 is arranged at the end of a support arm 19 and this is firmly connected to a part of the load-bearing structure, for example with a strut 20 of the derrick.
  • the clutch housing 17 can be released from the ball 18 and thus the clutch.
  • the chain guide 10 is supported by a supporting hollow profile 22, which attaches to the housing 9 of the chain drive and is firmly connected to it.
  • the chain guide consists of two elongated hollow profiles with a substantially rectangular cross section and inner guide slots in order to enclose the feed chain with its tabs 1a.
  • the chain stays consisting of the hinge pins 1b and the rolling sleeves 1c sitting on them, slide within the lateral guide slots 23 of the chain guide made of plastic.
  • the chain guide is surrounded by a protective jacket 24.
  • the locking links 3 are arranged on the hinge pin 1b. They are cranked sideways so that their grooves 5 are located on the same level. In addition, it is advantageous if the head parts of the locking links abut one another when engaging in the locking chain and do not form any gaps.
  • a collar 26 arranged on a pin 25 (FIG. 4) is used for the infeed.
  • a guide profile 27 with an incorporated guide curve 28 (FIGS. 3, 4 and 5) is provided for the discharge. The discharged part of the locking chain 3 is guided further outside within a guide channel 29.
  • the chain drive device is put into operation to move a load, not shown, which is suspended from the supporting cable 15.
  • the chain drive is moved from a position in the immediate vicinity of the lateral attachment of the chains 1 and 2 to the coupling 17, 18 into a position according to FIG. 2.
  • the chain drive wheel 13 engages in the feed chain 1 and pulls it by moving counterclockwise into the housing.
  • the locking chain is pulled into the drive housing.
  • the individual links of the locking chain run against the guide collar 26 and are pressed downwards into a position in which the locking links 3 with their grooves 5 lie against the chain stays, consisting of a joint pin and roller sleeves thereon.
  • Both chains are joined together with the locking members 3 to form a support element 11 which is rigid in two planes. This is able to absorb the pressure force for positioning the load.
  • the propulsion of the chain drive device to form the support element 11 can be seen particularly clearly in FIG. 8.
  • a part of the already assembled support can be seen in the continuous line in the left position, so that the support cable 15 is laterally deflected at a corresponding angle.
  • the compensation for the position level can be created by the interposition of the lift cylinder 16, which is illustrated by the arrow below the further deflected device shown in broken lines.
  • the lift cylinder 16 can optionally be replaced by an equivalent hoist, for example a winch. It is also conceivable to use other elements that are stiff in only one bending plane. Hydraulically, pneumatically or electrically operated versions are suitable as drive motors.
