Definitions

  • the present invention relates to devices used for the straightening of automobile bodies or the like.
  • the jack provided in these devices consists of a thrust jack arranged vertically and the movable rod of which comprises a head on which is fixed the end of the traction chain, opposite the end attached to the body to be straightened.
  • This chain passes beforehand on a return pulley carried by a collar, the position of which can be modified in the vertical direction, on the column of the device.
  • the extension of the push cylinder causes traction on the chain attached to the body to be straightened.
  • the traction chain instead of the traction chain being fixed directly to the upper head of the thrust cylinder, it can pass over a second deflection pulley provided on this head and be attached to a fixed point in the column of the device.
  • one or more extensions are adapted on the upper end of the vertical column, it is necessary to provide an extremely effective locking of these extensions, otherwise they risk being torn off during operation. of device.
  • the present invention relates to a straightening device which is designed to avoid the drawbacks of the systems of the prior art mentioned above (for example US-A-3888100).
  • the jack provided in this device consists of a long-stroke traction jack arranged vertically and whose body is hingedly mounted at the bottom of the column, however the traction chain, after having passed over a deflection pulley located at the upper end of the vertical column, engages inside this column and is fixed at the end to the free end of the rod of this jack.
  • this cylinder acts directly on the traction chain and the traction force actually exerted on the body to be straightened is substantially of the same value as the power of the cylinder used. Under these conditions it is possible to use a lower power cylinder than on the aforementioned devices. Furthermore, there is no need to provide a particular guide member at the upper end of the column since it suffices to allow free passage of the traction chain, the end of which is attached directly to the rod of the control jack.
  • the body and the rod of this jack are free inside the vertical column of the device and the lower end of the body of the jack is articulated on this column.
  • the jack can freely take the desired orientation so that the tensile force is exerted in a straight line, thus avoiding the drawbacks which may result from a misalignment.
  • the base of the vertical column has a horizontal bottom extending a short distance from the ground and this base is mounted on casters with the interposition of elastic buffers.
  • the reaction exerted on the base ensures the support of the bottom thereof against the ground, due to the compression of these elastic pads. This contributes to ensuring perfect immobilization of the device, the column of which is moreover held in place by two or more chains which are attached to anchoring points provided on the ground.
  • the body of the traction cylinder is slidably mounted in the vertical direction on its axis of articulation carried by the column of the apparatus and a retaining chain passing over a return pulley is then fixed on the lower end of this body of the jack, this chain being intended to be attached, at its opposite end, either to the upper end of the vertical column, or to a collar mounted on this column and carrying a pulley reference for the powertrain.
  • This arrangement automatically balances the forces exerted on the device.
  • the device according to the invention comprises a vertical column 1 carried by a movable base 2. Inside this column is placed a hydraulic traction cylinder 3 with long stroke which is arranged vertically.
  • the body 3a of this jack is attached at its lower end to the corresponding end of the vertical column 1 by means of a hinge pin 4.
  • the body of this jack and its sliding rod 3b can be oriented freely inside column 1 ..
  • This column has a square or rectangular section. In its upper end is swung a tip 5 of the same section comprising an end plate 6 provided with an opening 7.
  • This plate carries a yoke 8 inside which is mounted a deflection pulley 9.
  • On this pulley passes a traction chain 10, one end of which is intended to be attached to the body to be straightened. As for the opposite end of this chain, it penetrates inside the vertical column 1 by passing through the opening 7 of the upper end piece 5 to be fixed on the free end of the rod 3b of the traction cylinder. .
  • the end plate 6 of the end piece 5 has a bent extension 11 comprising a hole 12 having notches intended to allow the attachment of two retaining chains 13, as shown in Figures 1 and 2.
  • the opposite ends of these chains are attached to anchor points provided on the ground.
  • profiles 14 on the ground which surround the location of this body and the fixing of the retaining chains on these profiles is ensured by devices. hooking 15 adjustable position.
  • control cylinder 3 is a long-stroke hydraulic traction cylinder. This is controlled by a valve 17 comprising an operating pedal.
  • the movable base 2 rests on casters facilitating its movement, for example six casters 18, at the rate of three under one of the raised edges of this base and three others under the opposite raised edge.
  • this base is mounted on each of these rollers with the interposition of an elastic pad 19.
  • this base has a flat bottom 20 which extends a short distance e from the ground.
  • this device makes it possible to exert, under the best possible conditions of use and safety, significant traction forces on an automobile body to be straightened.
  • the chain 10 passing over the idler pulley 9, located at the upper end of the column 1, can then be attached directly to an appropriate point on the bodywork to exert an oblique upward traction according to the arrow F1, as shown in Figure 1. Since this chain 10 is fixed directly to the movable rod 3b of the traction cylinder, it suffices to have a cylinder having a power very slightly greater than the force which it is desired to exert on the bodywork to be straightened.
  • Another advantage of the present device lies in the fact that there is no need to provide a particular guide piece at the upper end of the vertical column 1 and that the traction cylinder 3 can be freely oriented by articulation. around the axis 4 to take the desired orientation in order to exert a traction in a straight line, which avoids the drawbacks of a possible misalignment.
  • Figures 6 and 7 show a particular mode of mounting the casters of the base of the device.
  • the arrangement is such that the vertical axis of the fixing bolt 21 of the yoke 22 of each corresponding roller 18a has, in the horizontal direction, an offset E with respect to the position of the horizontal axis 23 of this roulette.
  • an elastic buffer 19 is interposed between the top of the yoke 22 and the base 20 of the device.
  • Figures 8 and 9 show another mode of use of the device shown in Figures 1 to 5. In the case thus illustrated there is provision to exert traction in a horizontal direction F2 on the body to be repaired.
  • an additional pulley 24 is provided, carried by a collar 25 removably mounted on the column 1.
  • the chain 10 is then engaged around this pulley, as shown in FIG. 8 before passing over the upper pulley.
  • the collar 25 is slidably mounted along the column 1 so that its position can be modified so that it is placed in the desired position so that the working end of the chain 10 extends horizontally, as shown in FIG. 8.
  • an appropriate blocking system is provided making it possible to immobilize the collar 25 at the desired level.
  • the collar 25 is preferably removable in order to be able to be quickly put in place on the column 1 or to be removed therefrom, if it is desired to use the device according to the form of use illustrated in Figures 1 and 2.
  • this collar actually affects the shape of a yoke, the two cheeks of which are connected by a removable pin 26, on the side opposite the bottom 25a of this yoke and the return pulley 24.
  • a removable pin 26 on the side opposite the bottom 25a of this yoke and the return pulley 24.
  • This pin is applied against the corresponding face of the column 1 by means of a flat on which are provided teeth or hooking ribs 26a.
  • the bottom 25a of the yoke 25 carries a spring 39 which bears on the corresponding face of the column 1, which ensures the immobilization of the collar 25 at the desired level.
  • a spring 39 which bears on the corresponding face of the column 1, which ensures the immobilization of the collar 25 at the desired level.
  • any other suitable system could be provided for blocking the collar 25 in the chosen position.
  • the latter is preferably also removable.
  • its axis 27 is removable.
  • the retaining chains 13 are attached to the collar 25 and not to the upper end piece 5.
  • the two lateral cheeks of this collar include openings 30, in the form of buttonholes, likely to receive the corresponding ends of these chains as shown in Figures 8 and 9.
  • the bottom 25a of the yoke constituting the collar 25 has an extension 25b extending downward and which also has an opening 30 for the attachment of other ground retaining chains extending in the opposite direction from the chains 13.
  • Figures 10 and 11 show another embodiment of the apparatus according to the invention which is used in the same way as in the case of Figures 1 and 2.
  • This embodiment differs from the previous one in that the body 3a of the traction cylinder can move, by a certain distance, in the vertical direction relative to its corresponding axis of articulation 4a.
  • the lower end of the actuator body 3a carries a vertical tab 31 which can be fixed by means of a second articulation axis 32 and having an oblong opening 33 inside which the axis 4a is engaged.
  • this tab carries a yoke 34 in which is attached a retaining chain 35 passing over a return pulley 36 provided at the lower end of the vertical column 1a of the corresponding device
  • this retaining chain is arranged above the ground to be engaged around a second deflection pulley 37 carried by one of the devices 15 for anchoring to the ground, this chain then extending obliquely towards the top so that its corresponding end is attached to the upper end piece 5 of the vertical column. This end is then attached in the hole 12 of the extension 11 of this nozzle, two normal retaining chains 13 being arranged on either side.
  • this chain 35 constitutes one of the retaining chains of the apparatus.
  • FIG. 12 illustrates another mode of use of the device represented in FIGS. 10 and 11. This mode of use is similar to that illustrated in FIGS. 8 and 9. Indeed in this particular case the collar 25, carrying the additional return pulley 24 is placed on the vertical column 1 so that the working end of the traction chain 10 extends in the horizontal direction.
  • the retaining chain 35 fixed to the lower tab 31 of the cylinder body, is attached at its opposite end to this collar, at an appropriate point.
  • the device is then retained in place by two retaining chains 35, there is automatically obtained a balancing of the forces exerted on the device.
  • an additional collar 41 can be provided which can be mounted on the column 1 in the same way as the collar 25, this collar 41 being intended to allow adaptation of a traction cylinder 42 to which is attached a chain 43.
  • extensions intended to be adapted on the upper end of the column 1 after removal of the upper end piece 5, the latter then being adapted on the upper end of the last extension.
  • this or these extensions are then perfectly held in place on the upper end of the column 1 by the pressure exerted by the traction chain 10 on the pulley 9 of the end piece 5. It is therefore no need to provide a special locking system for the extensions on column 1.
  • the lower base 2 has holes 38 for fixing retaining chains intended to be anchored to the ground, such anchoring being necessary for the execution of certain particular works.
