Definitions

  • the present invention relates to a device for the height adjustment of a cover for a manhole.
  • the Italian patent application No. T02000U000032 for an utility model relates to a device for the height adjustment of a cover for a manhole, in which the device comprises a support frame for the cover which is suitable for sliding vertically in contact with an internal wall of the manhole, a number of internally threaded tubular elements which are arranged along the edge of the frame and which are integral to the frame itself, and, for each tubular element, a respective threaded metal pin, which is axially blocked against a base of the manhole, and which is engaged with the relative tubular element in order to be manually activated from the outside of the manhole itself in such a way as to raise the frame.
  • the aim of the present invention is to produce a device for the height adjustment of a cover for a manhole which is free of the above-described disadvantage.
  • a device for the height adjustment of the cover for a manhole comprising a support frame for the cover which is suitable for sliding vertically in contact with an internal wall of the manhole, a number of internally threaded tubular elements which are arranged along the edge of the frame and which are integral to the frame itself, and, for each tubular element, a respective threaded metal pin, which is engaged with the relative tubular element in order to be manually activated from the outside of the manhole itself in such a way as to raise the cover; the device being characterised by the fact of comprising an activating transmission which is coupled to all the pins and which is suitable for being activated by a single pin for the simultaneous activation of the pins themselves.
  • the number 1 refers to a device, in its entirety, for the height adjustment of a cover 2 arranged in such a way as to close a manhole 3.
  • the device 1 comprises a support frame 4 which in turn comprises a fixed portion 5 which is integral to a fixed internal wall 6 of the manhole 3, and a mobile support portion 7, which supports the cover 2 and which is coupled to the fixed portion 5 in an axially sliding manner in order to slide vertically in contact with the wall 6 itself.
  • the device 1 also comprises four internally threaded tubular elements 8 which are arranged along the edge of the frame 4 and which are integral to the fixed portion 5, and, for each tubular element 8, a respective threaded metal pin 9, which is engaged with the relative tubular element 8 and which is arranged through the mobile portion 7 in order to be manually activated from the outside of the manhole 3 itself in such a way as to raise the lid 2.
  • the mobile portion 7 comprises a plate 10 which is provided with a passing hole for each pin 9, which is provided with an hexagonal head 12, and which is axially coupled to the plate 10 by means of the interposition of two axial thrust block rolling bearings 13a and 13b, the first of which is blocked between the head 12 and the plate 10, while the second of which is blocked between the plate 10 and a ring nut/ferrule 14 which is integral to the pin 9.
  • the mobile portion 7 also comprises a lateral cylindrical wall 15 which is arranged along the edge of the plate 10 and which is integral to the plate 10 itself, and a cylindrical baffle 16 which is arranged on the plate 10 at a determined distance from the wall 15 in order to define with the latter an annular housing 17 which extends along the edge of the frame 4.
  • the fixed portion 5 comprises an annular plate 18 which is arranged transverse to a longitudinal axis A of the manhole 3 and which is integral to the wall 6 of the manhole 3 itself, and a respective cylindrical wall 19 which is supported by the plate 18 and which is coupled in an axially sliding manner to the wall 15.
  • Each tubular element 8 is at the bottom joined to the plate 18, and the upper part is provided with a plug 20, which is internally threaded and which is engaged with a relative pin 9.
  • the device 1 comprises an activating transmission 21, which is arranged inside the housing 17, and which is coupled to all the pins 9, and which is suitable for being activated by a single pin 9 in order to activate the pins 9 themselves simultaneously.
  • the transmission 21 comprises, for each pin 9, a gearwheel 22, which is angularly coupled to the relative pin 9, and which is arranged between the relative head 12 and the relative bearing 13a, and which is provided with an annular element 23 which is angularly coupled to each gearwheel 22.
  • the annular element 23 is defined by a chain which extends inside the housing 17 in such a way as to engage all the gearwheels 22, and the transmission 21 comprises, for each gearwheel 22, a chain tightener 24 which is arranged on the sides of the gearwheel 22 on the opposite side of the chain 23 in relation to the gearwheel 22 itself.
  • the device 1 comprises an annular cover 26 which is arranged in such a way as to close or be removed from the housing 17 in order to permit the access of the head 12 of at least one of the pins 9 in such a way as to act on the head 12 itself, for example by means of a socket head screw wrench, and simultaneously activate all the pins 9 themselves by means of the transmission 21.
  • each tubular element 8 With the aim of keeping the entire device 1 oiled, the housing 17 and each tubular element 8 are all internally filled with oiling grease, whose leakage from the tubular elements 8 is prevented by an extending bellows sleeve 26.
  • Each sleeve 26 is arranged outside the relative tubular element 8 and is also connected to the plate 10 in such a way as to also protect the portion of the metal pin 9 which juts out from the relative plug 20.
  • the frame 4 will no longer get stuck against the walls 6 of the manhole 3, as well as which the time necessary for the height adjustment will be much shorter in comparison to the time which is currently necessary to perform this operation because, as is clear from the above description, it is only necessary to act on a single pin 9.
  • FIGURE 3 The form of embodiment which is illustrated in FIGURE 3 relates to a device 1' which is similar to the device 1, from which the device 1' differs due to the fact that each gearwheel 22 is defined by a pulley, while the annular element 23 is defined by a positive drive belt 23' which is engaged with each pulley.
  • FIGURE 4 The form of embodiment which is illustrated in FIGURE 4 relates to a device 1'' which is similar to the device 1, from which the device 1'' differs due to the face that each gearwheel 22 is defined by a pulley, while the annular element 23 is defined by a rack 23'' which is engaged with each gearwheel 22.
