Definitions
- the object of the invention is a distribution system f concrete consisting of at least two tank vehicles, including pump vehicle equipped with a cab, which carry through-flow bu tanks equipped with an internal spiral, and a pump between t cab and the tank, and in which the loading opening of the bu tank is located at the rear of the vehicle and the dischar opening is set to discharge the bulk concrete into the funn of the pump; and which system includes at least one ta vehicle for bulk cargo transportation intended to transport t bulk concrete to the pump vehicle.
- the invention is intend for use in connection with both spray-concreting vehicles a those used for normal casting.
- bulk concrete mea generally various kinds of surfacing and other cpnstruction masses.
- Concrete spraying that takes place underground is usual carried out using a special vehicle designed for the purpos
- a tan pump and pipework carried on a jib and it can carry o concrete spraying independently at the work site.
- One kno concrete spraying vehicle is the type Normet NT, 120 Spraym ticTM.
- This chassis- steered vehicle is power by a dies motor, its front section includes the cab and a jib system carry the spraying pipes and nozzles.
- the rear section of t chassis includes a rotatable conical tank, which is ' locat with the opening facing rearwards. The pump is located benea this opening in such a way that its input opening is benea the opening of the tank.
- the patent application publication DE 2,264,088 shows a tan trailer that is intended for concrete distribution, which i equipped with a pump to transfer the mass to the point of use
- the feed funnel is located beneath the discharge funne of the tank.
- one man is required to supervise the pum and possible jointed jib and another at the point of use of th concrete mass to supervise the casting.
- a tank trailer of thi kind is poorly adapted to use in mines, because the discharg of the bulk concrete demands considerable vertical space.
- the tractor intended to pull the trailer canno be freed on account of lack of space.
- the intention of this invention is to create a new type o distribution system that is more efficient than the previou ones for both concrete spraying and casting.
- the characteris tics features of the system in accordance with the inventio are presented in the accompanying Patent Claims.
- the mai principle of the invention is to arrange the pump vehicle i such a way that it need not itself fetch the mass from abov ground.
- the pump in it is located behind the cab an its feed funnel is equipped with a device to prevent overfil ling, so that one man can supervise the pump, the jib, and th use of the concrete, when a single employee is sufficient a the point of work.
- the overfilling of the feed funnel is most advantageousl prevented by connecting it tightly to the discharge opening o the tank by means of a joint that permits rotation.
- the use o various kinds of sensors to give an alarm if overfilling take place is possible in principle, but they are of dubiou reliability.
- the interruption of the rotation the tank prevents it being filled.
- spray concrete is normal bulk concrete, which is dispersed in nozzle by compressed air.
- the system includes a bulk concre vehicle in accordance with Patent Claim'5.
- the techniqu known from the German application publication 2,263,088, patent publication 240,594, or Finnish patent applicati 890221 can be applied.
- the bulk tank of the pu vehicle can have a smaller capacity than previously, becau the system includes separate bulk concrete transportati vehicles.
- a horizontal tank that is open at both ends or o end can only be less than half filled, * but this is not disadvantage.
- the concrete mass flows through the tank of t pump vehicle and pumping is not interrupted for even the ti that it takes to fill the tank.
- Figure 1 shows vehicles of a system intended for concre spraying
- Figure 2 shows spraying and pump vehicles
- Figure 3 shows the connection between the pump and tank the vehicle in Figure 2
- Figure 4 shows the vehicle in Figure 2 seen from the rear
- Figure 5 shows a bulk concrete vehicle
- the use of a system in accordance with the invention f spraying concrete in mine tunnels is shown in Figure 1.
- typical underground construction the working height is smal
- the principal components of the system are the pump vehicle and the tank vehicle 10.
- the pump vehicle 1 is continually the point of work and its efficiency is thus excellent compar to previous systems.
- Vehicles 1, 10 include locating devices 17 and 18, in this ca a pin and a hole, by means of which ' it is ensured that t discharge opening 13 remains in place in relation to t opposing feed opening 5. This is quite essential, as t vehicles have suspension.
- the principal components of the pump vehicle 1 are a cab 2, bulk concrete tank 3, and concrete pump 4, Figure 2.
- the fro of the vehicle also includes a jib system 12 for concre spraying.
- the mass moves out of tank 3 by means of t internal spiral 8, when the tank is rotated.
- the mass th flows out of the discharge opening 6 directly into the fe funnel 7.
- Tank 3 can revol continuously and moves the mass from the discharge opening 6 much as there is space for in the feed funnel 7, but the stat pressure of the concrete mass in the raised feed funnel prevents overflow.
- the feed funnel 7 is open at the top, that the washing and servicing of the equipment is easy.
- the tight connection 14 between the tank 3 and the feed funn 7 of the pump 4 shown in Figure 4 is quite central to t operation of the pump vehicle 1.
- the funnel 7 includes a rubb flange 15, which is arranged to press against the conic surface 16 of the tank 3.
- the concrete mass that is press into the funnel 7 further presses the rubber flange 15 again the conical surface 16, so that the connection remains tig even when loaded.
- FIG 4 shows the pump vehicle 1 from the rear.
- the fe opening 5 is formed of a large rubber flange 21, the diamet of which is about 1.5 and the diameter of the opening in is about 0.6 m. This makes possible a large difference of ang between the tanks 3 and 11 to be coupled together.
- the chassis of the pump vehicle 1 has a swivelling rear cov 9, which can be pressed against the rubber flange 15 f example during temporary transportation or mixing of the mass
- Vehicle 1 needs no more than one person to supervise the enti operation of the pump vehicle 1.
- the person in t cab 2 supervises the operation of the spraying nozzles a controls the jibs 12 that direct them, because the feeding pump 4 no longer requires continual supervision.
- the pump and the jib equi ment is most advantageously controlled from the point casting itself by means of a suitable remote-control device.
- Figure 5 shows a bulk concrete tank vehicle 10, the principa task of which is to transport bulk concrete from a concret plant to the tank of a pump vehicle.
- Vehicle 10 includes rotatable tank 11, inside of which there is a spiral 8 to mov the mass out of the tank.
- the discharge opening 13 of the tan 11 is arranged to fit the feed opening 5 of tank 3 in such way that the discharge opening 13 fits suitably inside fee opening 5.
- This horizontal transfer of the mass is know from the aforementioned patent publications.
- the pumping of th concrete and its spraying is not disturbed during the fillin of tank 3. Even under difficult conditions the operator of th pump vehicle need interrupt his work only while coupling i taking place.
