The holes are filled to accommodate the arms of the forklift.

3. The unit according to claim 1, characterized in that each of the fastening devices is additionally equipped with a pair of positional elements mounted on the upper sections of the invention. The invention relates to transport engineering, in particular, to the base structures on which the power units T1 of sports equipment are placed,

The purpose of the invention is to simplify the design.

FIG. 1 schematically shows a dump truck with a removable power unit, general view; in fig. 2 - the same, vdv in the plan; in fig. 3 is a section A ™ A in FIG. one; FIG. 4 shows a securing device; in fig. 5 is a section BB in FIG. four; in fig. 6 is a view of B in FIG. five.

The invention is considered by the example of a dump truck driven by a two-axle engine with front driven wheels (Figs, i and 2). The dump truck contains a body I with a cab 2 placed on it at its front end, an open cargo body 3 movably mounted on the main frame and used for transporting cargo and unloading it, and a pair of front and rear dual wheels 4 and 5, the front wheels 4 can control performed by a conventional steering gear.

As shown in FIG. 2, the movement of the dump truck is provided by electric motors 6 built into all wheels 4 and 5. The latter are powered from an electric power unit 7 installed in the compartment 8 located in front of the cab 2 and controlled by wheels 4 and located across the car,

FIG. 3 shows the power plant 7, the latter is placed on a common elongated base 9 detachably mounted on a dump truck, thus forming the removable bottom of the compartment 8 of the power plant 7. The power hoBKa includes the electrical surface of the upper plate of the hollow element, which when installed the removable base on the vehicle is placed in rectangular apertures opposite one another and adjacent to the lateral ends of this hole in its longitudinal direction.

torus 10 (direct or alternating current) and two opposed primary engines 11 (diesel engine or gas turbine). The mechanical energy of the prime movers through the generator is converted into electrical energy by supplying the electric motors for driving the wheels 4 and 5.

If necessary, the prime movers 11 are equipped with radiators 12, as well as cooling fans 13. For this purpose, the air intake manifold 14 is made in the front wall of the power plant and is closed

lattice.

Figs 3-6 illustrate an embodiment of a removable base 9 with a fastening device 15,

Removable base 9 is formed in

a box consisting of an upper plate 16, a lower plate 7, vertical side plates 18 I-19, a vertical front plate 20 and a vertical back plate 2 between which a hollow space is formed. Removable base 9 is fixedly mounted by at least two or more fastening devices 15 placed on a pair of box-shaped blocks.

the frame 22, fixedly attached, as one unit, along the bottom of the body 1 of the dump truck. The frame blocks 22 are arranged parallel to each other along the longitudinal direction of the body 1, and in space

Between them, reinforcing elements 23 are provided, attached at right angles to the frame blocks. Each of the fixing devices 15 has a pneumatic or hydraulic

a cylinder 24 fixedly attached to the element of the side plate 25 of each frame unit 22. In the cylinder 24 there is a spring 26, working in compression, pressing on the piston 27,

in order to create axial pressure on the piston rod 28 fixedly connected at one end to the piston 27. At the other end of the piston rod 28 is movably connected to one end of the swinging lever 29 via the yoke 30 and the rotation pin 31. Positions 32 and 33 designate bushings that are mounted on the shaft 34 between each side of the rocker arm 29 and the elements of the upper and lower plates 35 and 36, respectively, to prevent lateral play of the rocker arm 29. The tightening shaft 34 inserted in the slotted manner in the bush, formed at the other end of the swing arm 29, passes vertically from the element of the lower plate 36 of the frame unit: 22 to its element of the upper plate 35 and, in addition, passes through a rectangular opening 37 formed in the lower plate 17 and enters the hollow space volume many bases 9. The upper end of shaft 34 entering the hollow space has the shape of a hole 37 in cross section, but slightly less than a hole 37. The opposite end of shaft 34 is formed in the shape of a part with a smaller diameter, so as to maintain-30 la can pass through the hole

37. Under this condition, the forklift of the forklift truck is inserted into the holes 1 44 and 45, respectively, in the front plate of the removable base 9. The removable base

on the upper surface of the element of the lower plate 36. The opposite lower end of the shaft 34 passes through the element of the lower plate 36 and is threadedly connected to a nut 38 secured by means of a cylinder 39 on the shaft 34. To ensure the density of the shaft 34 between the detachable base 9 and each of the blocks of the frame 22 and the paraphernalia of the elements of the wedge-40 visible cams 40 and 41 are fixedly attached to the upper surface of the bottom plate 17 of the volume base 9 in the immediate vicinity of the surface is removed.

In the case of installation and securing of a power plant with a removable base 9, the latter is carried by a forklift over the front ends of the frame blocks 22 and lowered onto them so that each pair of elements 42 and 43 which are installed in the correct position fit tightly into both ends of each hole.

one of the lateral end of the orifice 37 of the constitution 37. Then the liquid, which is

responsibly symmetrically with each other relative to the center of the hole 37. At the locations on the upper surface of the element of the upper plate 35 of the frame block 22, which correspond to both longitudinal ends of the hole 37, a pair of elements 42 and 43 set to the desired position are fixed to it . Positions 44 and 45 denote holes (Fig. 2) formed in the front plate element 20 of the removable base 9, into which the forks of the forklift truck are inserted in the case of 5 removals of the electric power unit 7 together with the removable base 9 from the dump truck body 1,

In case of removal of the electrical installation 7 together with a removable base

By using 9 dump truck body 1 to ensure easy maintenance, repair and inspection, fluid is first introduced for the pneumatic or hydraulic system from its source

5 into the chamber of the cylinder 24, the air- or oil-tightly separated piston 27 from the chamber with a spring, so that the piston rod is drawn into the cylinder 24 by a sliding movement of the piston in it in

The direction opposite to the direction of displacement of the spring 26 rotates the lever 29. In response to the turning movement of the lever 29, the shaft 34 rotates so that its head

5, 46 comes out of engagement with the elements of the wedge-shaped cams 40 and 41 and is aligned parallel to the hole 37 so that when the removable base vertically rises, the head 46 is released.

In the case of installation and securing of a power plant with a removable base 9, the latter is carried by a forklift over the front ends of the frame blocks 22 and lowered onto them so that each pair of elements 42 and 43 which are installed in the correct position fit tightly into both ends of each hole.

the chamber of the cylinder 24 is full, descends in a known manner, so that the piston rod 28 is pushed out of the cylinder 24 by the force of displacement of the spring 26. As a result, the lever 29 rotates, rotating the shaft so that the head 46 of the shaft 34 again engages with a pair of elements of the wedge-shaped cams 42 and 43 , thus providing a tight hold between the removable base 7 and the blocks of the frame 22.
