Definitions

  • the present invention relates to an apparatus for the assembly by interlocking of large diameter pipes, in particular concrete pipes used mainly for sanitation.
  • Each pipe is generally lowered, surrounded by an elinque attached to a crane, above the bottom of the excavation, so that its male end is located substantially opposite the female end of the pipe previously laid.
  • a cable type traction device is then hooked to a sling placed for example around one of the pipes already laid.
  • the hook of the traction device is connected to the sling supporting the pipe to be laid and the male end of the pipe to be laid is inserted into the female end of the pipe already laid by operating the traction device.
  • the hose must remain suspended from the lifting sling.
  • the interlocking of two pipes can also be carried out by traction inside the pipes, using a traction device generally supported, on the one hand, on a manhole placed every forty to sixty meters in such sanitation pipes and, on the other hand, on a plank, an iron bar or the like applied crosswise against the inner stop collar of the female end of the pipe to be laid.
  • a traction device generally supported, on the one hand, on a manhole placed every forty to sixty meters in such sanitation pipes and, on the other hand, on a plank, an iron bar or the like applied crosswise against the inner stop collar of the female end of the pipe to be laid.
  • Pipe interlocking devices have also been proposed which are movable on a carriage inside the pipes already laid in a pipe and can be immobilized by a locking device in one of the last pipes laid, so as to serve point of support for a traction device acting on the next pipe to be fitted.
  • the apparatus according to Swiss Patent No. 450 841 is however very bulky since it extends over the length of several pipes and its implementation is complicated.
  • the apparatus according to US Pat. No. 3,486,214 does not ensure certain blockage when the traction device is put into action.
  • the main drawback common to these known devices lies in the fact that they do not provide any protection for the personnel who is responsible for laying the pipes and who must manually guide the pipe to be laid, during its fitting.
  • the present invention relates to an apparatus which simplifies the assembly by fitting of large diameter pipes and significantly reduces the risks of laying such pipes.
  • the invention also relates to an apparatus which makes it possible to reduce the cost of laying these pipes.
  • the present invention therefore relates to an apparatus for the assembly by interlocking of large diameter pipes, of the type comprising a carriage capable of rolling inside the pipe or pipes already laid, a device for immobilizing said carriage in the last pipe laid, consisting of at least one strut of a length slightly greater than the inside diameter of the pipes and articulated by a horizontal transverse axis on said carriage so as to be able to be blocked in the last pipe laid, its two ends bearing against the inner face of this pipe at two roughly diametrically opposite points, and a traction device mounted on said carriage and bearing on the next pipe to be laid.
  • the strut carries a vault articulated by a horizontal transverse axis on the upper end of the strut and extending, over part of its length, the free end of the last pipe laid when the device is immobilized near this end.
  • This vault allows, after having immobilized the trolley in the last pipe laid, to level and center the pipe to be laid in relation to the pipe already laid, which ensures the fitting of the pipe to be laid in the pipe already laid by the simple operation of the apparatus traction.
  • the articulation of the arch by a horizontal transverse axis on the strut allows the pivoting of the arch relative to the strut for the correct application against the inner face of the last pipe installed, when blocking the 'apparatus by pivoting the strut in one direction, and for movement of the device in the pipes, after release of the strut, by pivoting the latter in the opposite direction.
  • the traction device is articulated by a transverse horizontal articulation axis on the strut, between the axis of articulation of the latter on the carriage and the lower end of the strut.
  • an operating member is mounted on the carriage to pivot the strut and block it in the last pipe installed by bringing said arch and an articulated sole on the lower end of the strut, against the inside of said pipe.
  • said strut is adjustable in length.
  • the latter comprises a spring for pivoting the strut relative to the carriage against the action of said operating member.
  • the device comprises a compression spring between the strut and the arch, in front of the articulation axis of the arch on the strut.
  • the apparatus according to the invention used to assemble two pipes 1, 2, for example of concrete comprises a carriage 3 capable of rolling inside the pipes.
  • the carriage is formed by a chassis 4, preferably welded, carried by two front wheels 5 and two rear wheels 6.
  • the wheels are inclined outward so that the planes of said wheels are substantially perpendicular to the tangent to the inner periphery of the hose, at the point of contact of each wheel with said perimeter
  • Two telescopic struts 8 are articulated on the chassis 4, by two articulated axes 7 aligned, horizontal, perpendicular to the ongitudinal axis of the carriage 3, so as to be able to pivot in two longitudinal vertical planes of the carriage 3.
  • Each leg of force 8 comprises an outer tubular section 9 articulated by said axis 7 on the chassis 4, a median tubular section 10 protruding on either side of the section 9 and capable of sliding in the latter, as well as an inner section 11 exiting towards the top of the median section 10.
  • the tubular section 11 has transverse holes making it possible to limit, using pins not shown or the like, the depth of insertion of the section 11 into the section 10.
  • the two tubular sections medians 10 are interconnected, substantially at their two ends by two spacers 12.
  • Each of the two tubular sections 10 has, at its lower end, a sole 13 articulated by a ball joint on the section 10.
  • Two hydraulic cylinders 14 are articulated on the rear of the chassis 4 along articulated axes 15, horizontal, perpendicular to the longitudinal axis of the carriage 3, so as to be able to pivot in the same planes as the struts 8.
  • the piston rod of each of these jacks 14 is articulated on the tubular section 10, below the chassis 4, substantially at the lower end of the section 10, by hinge pins 16.
  • a tension spring 17 extended by a threaded rod 18 is hooked to each of the axes 16, the nut 19 screwed onto the threaded rod 18 bearing on a projecting lug 20 fixed at the rear on the tubular section 9.
  • the spring 17 seeks to raise the section 10 by compared to section 9 in which it can slide.
  • a vault 21 is articulated around two aligned axes, transverse, horizontal, so that said vault can pivot relative to the struts 8 in a vertical plane longitudinal of the carriage.
  • the vault 21 is made up of several curved segments 23 articulated one on the other along longitudinal axes 24.
  • the two tubular sections 11 are articulated on the two outer segments 23 of the vault.
  • a compression spring 25 is inserted between the upper end of each tubular section 11 and the arch 21, in front of the hinge pins 22, so that the springs 25 seek to pivot the arch 21 as a whole in the direction counterclockwise in fig. 1.
  • a hydraulic cylinder 26 is mounted below the chassis 4, in the median longitudinal plane of the carriage 3.
  • the cylinder 26 is articulated by a horizontal transverse axis 27 on the lower cross member 12. Its piston rod 28 which extends towards the front ends with an eye 29.
  • the jack 26 is supported in a substantially horizontal position by a stirrup 30 fixed below the chassis 4.
  • the cylinders 14 and 26 are controlled, passing through a distributor 31, by a pump common hydraulic system 32 which, in the example shown, is operated manually using a lever 33.
  • the spacing of the left and right wheels (track) both at the front and at the rear is adjustable, namely by the fact that the yokes 34 carrying the wheels can be fixed with variable spacings on the chassis 4, for example using bolts 35.
  • the front wheels 5 can be oriented by the fact that their yokes 34 are fixed on a common support 36 articulated by a single central bolt on the chassis 4. This orientation of the front wheels can be advantageous for example to move the device outside of pipes.
  • Pipe 1 constitutes the last pipe laid in a series of pipes, for example concrete, constituting a pipe of a sanitation system. In the case shown, it is a question of assembling another pipe 2 with the pipe 1.
  • each of the pipes 1, 2 comprises a female end 37 with a collar and a male end 38 intended to be fitted into the end piece.
  • the male end 38 carries an elastomer seal 39 placed in a groove provided on the male end 38.
  • the vonforme device according to the invention placed inside the pipe 1, is advanced towards the free end of the latter, in this case towards the female end 37, so that its front wheels 5 are located near the female end 37.
  • the overall length of the struts 8 is adjusted so that it is somewhat greater than the diameter of the pipes.
  • the jacks 14 are not under pressure and the struts 8 occupy a more inclined position relative to the vertical than in FIG. 1, under the action of the springs 17.
  • the soles 13 and the arch 21 do not come into contact with the internal face of the pipe 1.
  • the pump 32 is then operated to send pressurized oil to the cylinders 14 using the distributor 31, the piston rod 15 of which thus emerges from the cylinder.
  • the flanges 13, on the one hand, and the arch 21, on the other hand, are supported at two more or less diametrically opposite points against the internal face of the pipe 1, which blocks the device with respect to pipe 1, the track 21 projecting beyond the female end 37 over part of its length.
  • the pipe 2 is then brought, suspended for example from a sling, its male end 38 being turned towards the female end 37 of the pipe 1, from the top and from the right in FIG. 1, in line with the pipe 1, so that the upper part of its male end 38 comes to bear by its internal face on the vault 21.
  • the piston rod 28 of the jack 26 is attached to the eye 29 one end of a cable 40, the other end of which is subject to a counter-supporting element 41, for example a plank or an iron bar, placed crosswise in the collar of the female end 37 of the pipe 2.
  • the person operating the device is in the immediate vicinity of the fitting area of the two pipes and can therefore, on his own, perfectly monitor the fitting operation.
  • This person can, preferably, enter the pipe to be laid as soon as the latter has, for example, descended into the excavation and is nearby above the bottom of the latter. It then always remains inside the pipe to be laid, therefore protected from any risk of the excavation falling.
  • a possible fall of the pipe to be laid would not, from this moment, have any more unfortunate consequences since the height of fall would be low and the person inside the pipe could support it without any damage.
  • the apparatus according to the invention is designed so as to leave the center of the pipes free to allow the passage of a laser beam used as a guide means for laying pipes composed of nested pipes.
