Definitions

  • hinged ladders are applied on fire trucks, of which upper part can be bent toward the building to aim the drainpipe at fire point and allow the ladder supported by the building exterior for stability of the ladder.
  • Fig. 1 shows the structure of the high elevated ladder of fire truck in accordance with the present invention.
  • Fig. 5 is a partial exploded perspective view of Fig. 3.
  • the present invention presents extendable telescopic drainpipe along ladder, having a bending apparatus at the position corresponding to the hinged point of the ladder, in order to provide a drainpipe without additional joint member up to the top of the ladder.
  • the extension and bending apparatus for fire truck drainpipe in accordance with the present invention is,
  • the said bending apparatus is formed with hemispherical mounting groove inside the upper member and inlet hole, inside the lower part, connected with drainpipe,
  • Fig. 1 shows the structure of elevated ladder for fire trucks applied with the present invention.
  • An extendable ladder(200) is installed on fire truck(100), and on the side of the ladder(200) a metallic drainpipe(300) is installed.
  • the said drainpipe(300) consists with multiple metallic drainpipes(301, 303, 304) of different diameters, connected telescopically for free extension and shrinking.
  • the drainpipe(301) which has the largest diameter is mounted on the ladder(200) with supporting rod(302).
  • At the top and bottom of the drainpipe(301) are formed with telescopic columns(305, 306) in which upper and lower drainpipes(303,304) are inserted and can slide in and out.
  • the said telescopic columns(305, 306) have sealing members inside to prevent upper and lower drainpipes(303, 304) from being isolated and fire water from leaking out.
  • the upper pipe(304) When the ladder(200) is being shrunk, the upper pipe(304) is inserted into the large pipe(301). When the upper pipe(304) has been inserted completely, the large pipe(301) moves downward with the ladder(200) receiving the lower pipe(303) inside.
  • the upper part of the said ladder(200) can be bent with a hinge(230) for easier approach to tall buildings and control of fire water discharging point.
  • the drainpipe(300) When the ladder(200) is bent, the drainpipe(300) also has to be bent at the same position with a bending apparatus(A) to enable watering at objective fire point.
  • the upper part of the ladder(200) can be bent to form a bendable ladder(210) of which one side of the bending direction is coupled with the upper part of the ladder(200) with a hinge(230) so that the upper part can be bent by rotation, while the other side is joined with the cylinder rod of hydraulic cylinder(220) of which main body is joined with the opposite side of the ladder(200).
  • the upper part of the drainpipe(300) has to be able to be bent at the position where the bendable ladder(210) is bent to enable watering at desired direction.
  • a bending apparatus(A) is provided.
  • the said bending apparatus(A) consists with fixed a member(320) and a rotating member(330). Bending is implemented by the rotation of the rotating member(33) inside the fixed member(320).
  • the said fixed member(320) is formed with hemispherical mounting groove(323) inside its body where the rotating member(330) which has ball-shaped body(331) is coupled by ball-joint type.
  • the said fixed member(320) is formed with an inlet(322), at the bottom of the mounting grove(323), which is connected with the exterior of the body(321).
  • the upper drainpipe(304) on the lower side is joined with the bottom of the body(321) of the fixed member(320) and connected with the inlet(322) to enable the fire water coming in through the upper pipe(304) can flow into the body(321) of the fixed member.
  • the body(331) of the rotating member(330) is mounted on the said mounting groove(323), having the diameter same as the inner diameter of the mounting groove(323), and formed with a pipe connection hole(332) inside.
  • an outlet(333) which is extended in a certain length, as a pipe, which is formed to connect the water flow path on top of the pipe connection hole(332) of the body(331).
  • the bottom of said pipe connection hole(332) has larger diameter than top, and desirably, has the diameter expanded towards the direction of bending.
  • the pipe connection hole(322) can maintain connection with the inlet(322) when the rotating member(330) is bent.
  • an o-ring type sealing member(324) is mounted on top of the mounting groove(323) and bottom of said holding member(325) to prevent water coming in through inlet(322) from leaking out of the fixing member body(321).
  • a pipe-type outlet(333) is formed in connection with the pipe connection hole(332), inside of which is inserted with the bottom of the bending drainpipe(340), and o-ring type sealing member(334) is mounted inside the outlet(333) to prevent water from leaking.
  • the bottom of the bending drainpipe(340) has a certain amount of gap to the pipe connection hole(332) which is formed on the rotating member body(331). This is because, since the upper part of the bending drainpipe(340) is fixed to the upper part of the bending ladder(210) with a bracket-type pipe fixing member(340), there should be some free space to prevent interference between the bottom of the bending drainpipe(340) and pipe connection hole(332) when the drainpipe(340) is inserted into the pipe connection hole(332) for bending, as shown in Fig. 3.
  • the drainpipe(300) is shrunk according to the bending of the ladder(210) since the bottom of the upper drainpipe(304) which is connected with the bottom of the fixing member(320) is inserted into the large drainpipe(301) by a certain length.
  • the fire water fed from ground comes into the inlet(322) through the lower drainpipe(310) and discharged through the pipe connection hole(332) and outlet(333), and to desired fire point through the upper drainpipe(340).
  • a telescopic drainpipe is installed along with the ladder, the drainpipe can be bent in correspondence with the bending of the ladder, to extend the drainpipe up to the top of the ladder, enabling fire water discharged towards the fire point accurately maintaining the water pressure.
  • the bottom of the bendable drainpipe(340) is inserted into the pipe connection hole, and at the same time, the upper drainpipe(304) is inserted into the large pipe(301) in the telescopic column(306), to enable smooth bending of the drainpipe preventing deflection or damage.
