Description

The invention relates to a vehicle, namely vehicles intended for the transport of emergency vehicles.

The aim of the invention is to improve the convenience of loading an emergency vehicle.

FIG. 1 schematically shows the proposed device, side view, with one emergency vehicle, prepared; one designed for rolling; in fig. 2 - the same, with two vehicles; in fig. 3 is a view A of FIG. one; in fig. 4 — lateral guides with retractable tracks and power equipment, side view; in fig. 5 is a view B in FIG. four; in fig. 6 is a view of B in FIG. four; in fig. 7 is a cross-section of the FIG. four.

The proposed vehicle for rolling in and transporting emergency vehicles comprises side guides 1 rotatably mounted on axles 2 on subframe 3 frames 4 tons of gauge 5.

Each of the lateral guides is made in the form of longitudinal profiled beams 6, rigidly interconnected by crossbars 7-9. The crosspiece 7 on the bracket 10 is set with the knowledge of the asterisk li, and on the crossbar 8 is the drive sprocket 12, kinematically connected by the shaft 13 to the gearbox 14 of the hydraulic motor 15.

In frame 4, on axis 16, a power saw 17 is rotatably mounted with a brush 18 connected to cross bar 9 by means of a bow 19.

The sprockets 11 and 12 are interconnected by a chain transmission 20, the ends of which are rigidly attached to the upper edge of the sliding track 21.

At the same edge of the track 21, an axis 22 is embedded, at the ends of which rollers 24 are mounted in bearings 23. Beams 6 are connected with a roller table 25, on which track 21 is supported during its telescopic extension from side rail 1 and during cleaning initial position. Each of the sliding tracks 21 is installed with a possibility of turning in a vertical plane relative to the side guides an angle in the range of 180-120 °,

At the rear edge of the track 21 pivotally on the axis 26 a pivot-mounted P-image is installed on a supporting paw 27 with oblique thrust 28.

In cross section, the tracks 21 and the side guides are trough-shaped with restrictive convex edges 29.

Front wheel stops 30 are mounted on rails 1 at the cab of the gacha 5.

The vehicle is equipped with additional means in the form of a telescopically extendable boom 31 on the base 32 with the end switch 33 and the winch 34 with the load cable 35 stored in blocks 36 and 37,

I have a hook 38 for grabbing the frame of the emergency vehicle 39 and sunk-TAKING. I drive it to the vehicle 5 (tons of gauge) along the tracks 21 to the guides 1.

The base 32, the boom 31, and the end 33 serve to mount and transport in a lift over the front wheels of another emergency vehicle 40.

The device works as follows.

In transport position without emergency cars, slide 21 by means of hydraulic motor 15, gearbox 14, shaft 13 and sprockets 12 and 11 with a chain transmission of 20 watts into the inside of guide 1. Power cylinder 17 is assembled and guide 1 is horizontal. position When an emergency car is rolled up, for example, a car 39, t hach 5 is reversed, undershoots about 4-5 m, stops r hl5 and turns on a hydraulic pump that is on a t hub (not shown), at which the power cylinder 17 raises the leading edge of the guide 1 to the desired height for the convenience of rolling which turns on axis 2.

Next, the hydraulic motor 15 starts up, which transmits the movement through the gearbox 14 and the shaft 13 to the sprockets 12 and 11, and the tracks 21 are pushed out of the guides 1. When the tracks 21 are extended, the latter roll on the rollers 24, resting on the roller tables 25 to the lowest position.

After extension of the tracks 21, the latter are adjustable at an angle to the directions 1, 1, the angle being chosen from 180 to 120 ° depending on the size of the rear overhang of the emergency vehicle, while the support foot is on the ground in front of the wheel.

Adjusting the angle of the guides I and tracks 2 is achieved by raising or lowering the leading edge of the guides.

Turning the winch 34 off the cable 35 and the hook 38 and the hooks (not shown) fix the emergency vehicle 39 on the cable 35.

Turning on the winch 34 rolls the emergency vehicle along the tracks 21, while the wheels are centered relative to the tracks using thrusts 28 of U-shaped supporting legs 27. Rolling is achieved up to the stop in the wheel stops 30. The turning of the supporting legs 27 around the axis 26 brings them under the rear wheels emergency vehicle wheels. Adjustment of the distance between the U-shaped onorny paws 27 and wheel stops 30 is achieved by moving the latter into the holes in the rails (not shown) and extending the tracks 21.

By means of the hydraulic cylinder 17, the guides 1 are lowered onto the subframe, while the winch 34 is simultaneously turned on, choosing the slack of the cable 35.
