Description

The invention relates to ground transportation systems.

Known NTS (ground transportation systems), designed to deliver people to hard-to-reach places on roads without hard surface, the so-called "shift" on the chassis of four-wheel drive cars - (A brief automotive guide. Volume 1. Buses / Kisulenko B.V. and others. - M .: NPST Transconsulting, 2002. - 360 p.). The most commonly used vehicles are the Urals or KamAZ, for example, NEFAZ-42111 on the KamAZ-4326-02 chassis with a 4 × 4 wheel arrangement (p. 221); NEFAZ-4208 on the KamAZ-43114-000 chassis (p. 217) with a 6 × 6 wheel arrangement.

Such cars have limited capacity and are not intended for a long stay of people in them, since the chassis has insufficient carrying capacity.

A large carrying capacity with high traffic can provide wheeled transport systems based on patent RU No. 2423281 C1; B62D 53/00; B62D 3/04; F 37/08. Bull. No. 19 dated 07/10/2011. Authors: Nekrasov V.I., Shiyka A.P.

The cargo platform of the wheeled transport system has significant dimensions and is installed on two wheeled carts, each of the carts is supported by 8 wheels. The power cylinders of the wheeled trolleys can lower the loading platform onto the roadway and raise it to a considerable height.

The disadvantages of the described design are that it has a limited capacity and is not intended for a long stay of people in it.

Closest to the proposed design of the transformed body is the application for the alleged invention WO 00/069095 A1, 11/16/2000, which describes an expandable trailer (10) for transportation and deployment of electronic satellite communications equipment. The trailer has, as a rule, a horizontal support frame (22). The expansion module (20) is located in the side wall, it has a vertical front panel and rear panel ...

The disadvantage of the described design is that it is not designed to accommodate people in it, has limited capacity, the deployment of the body with expansion modules is difficult, as it is done manually.

The problem to which the invention is directed, is to improve the operational and layout characteristics of the body of the NTS (ground transportation system).

The problem is solved by transforming the body mounted on the chassis of the NTS heavy-duty, due to the extension by the hydraulic cylinders of the middle and inner shells from the outer shell.

The essence of the proposed device lies in the fact that the transformed body of the ground transportation system, mounted on the chassis of this system with a support frame, contains a housing with expansion modules, while the body consists of an external housing, inside of which there is a middle housing with an internal housing installed in it, external the ends of the middle and inner housings are supported by rollers on the rollers, on the wheeled carts of the chassis fixed are the bodies of telescopic hydraulic cylinders deployed in opposite directions, the internal retractable e units with hydraulic cylinders attached to them levers interconnected cable, internal links retractable upper cylinders disables levers interconnected with the inner housing and the inner links of the lower sliding cylinders disables levers - with an average body.

In FIG. 1 shows a side view of the NTS, in the middle of which a transformable body is located on the loading platform.

In FIG. 2 shows a cross section of the fusion line. For convenience of design consideration, telescopic hydraulic cylinders in this and subsequent figures are shown above the body, in fact they are located on the side (Fig. 1).

In FIG. 3 is a side view with an extended inner case.

In FIG. 4 shows a side view with extended inner and middle bodies.

In FIG. 5 shows a view of telescopic hydraulic cylinders in a folded state with the transport position of the NTS, which corresponds to FIG. 1 and 2.

In FIG. 6 is a view in which the lower telescopic hydraulic cylinder has advanced the inner housing, which corresponds to FIG. 3.

In FIG. 7 shows a state in which the upper hydraulic cylinder moves the middle body and returns the lower hydraulic cylinder to its original (compressed) state. The inner casing is disconnected from the lower hydraulic cylinder and is in the extended position.

In FIG. 8 shows the final state of the upper hydraulic cylinder, the middle body is extended to its extreme position, which corresponds to FIG. 4. The arrow in the lower hydraulic cylinder corresponds to the initial phase of the return of the middle body to its original (transport) state.

In FIG. 9 shows the operation mode of the upper hydraulic cylinder, in which it returns the inner casing to its original state.

On the loading platform 1 of the NTS, located between the wheeled trolleys 2, a transformable body 3 is installed, consisting of an outer casing 4, inside of which there is a middle casing 5 with an inner casing 6 installed in it. 8. On wheeled trolleys 2 fixed housing of telescopic hydraulic cylinders 9 and 10, deployed in different directions. The inner retractable links 11 and 12 of the hydraulic cylinders 9 and 10 with the levers 13 and 14 fixed to them are interconnected by a cable 15. The inner links 11 of the upper hydraulic cylinders 9 (one on each side of the outer casing 4) by disconnected levers 16 are interconnected with the inner casing 6, and the inner links 12 of the lower hydraulic cylinders 10 switchable levers 17 - with the middle body 5.

The device operates as follows. In the transport position, the transformed body 3 of the ground transportation system (Fig. 1) is located on the loading platform 1 between the wheeled trolleys 2 and is raised above the road surface. The inner 6 and middle 5 of the body of the transformable body 3 are installed inside the outer case 4 (Fig. 2 and 5). The inner sliding links 11 and 12 are located completely inside the hydraulic cylinders 9 and 10, the levers 17 hold the middle body 5, and the levers 16 hold the inner case 6. To deploy the convertible body 3, the power cylinders of the wheel trolleys 2 lower the load platform 1 onto the roadway (Fig. 2 -four). The hydraulic fluid of the hydraulic actuator (not shown) presses the internal sliding links 11 out of the hydraulic cylinders 9 (one on each side - Fig. 1) and levers 16 pushes the inner casing 6 (Fig. 6), which rests on the racks 7 and moves on the rollers 8 (Fig. 3). The levers 16 are disconnected from the sliding links 11, we supply pressurized hydraulic fluid to the hydraulic cylinders 10, which acts on the sliding links 12, they pull the levers 13 through the cable 15 through the cable 15 and return the sliding links 11 to their original position. At the same time, the retractable links 12 by levers 17 pull the middle body 5 from the outer link 4 of the convertible body 3 (Fig. 7). The final stage of this movement of the middle body 5 on the uprights 7 and rollers 8 is shown in FIG. 4 and 8. The transformed body 3 is brought into a deployed stationary position. Transfer to a transport state occurs in the reverse order. We supply the working fluid under pressure to the hydraulic cylinders 9 (Fig. 8, bottom view), the retractable links 11 by the levers 13, the ropes 15, the levers 17 move the middle body 5 into the outer case 4, while the levers 14 return the retractable links 12 to the hydraulic cylinders 10. Levers 17 we disconnect from the sliding links 12, we supply the working fluid under pressure to the hydraulic cylinders 10, which acts on the sliding links 12, they pull the arms 13 through the cable 15 through the cable 15 and return the inner casing 6 and the sliding links 11 to their original position (Fig. 9). Transformable body 3 is brought into transport position. Retractable links 12 are returned to their original position either manually by turning on the hydraulic pump to pump out the working fluid or due to return springs (not shown).

The proposed design of the transformed body can find application for delivery to the place of work of the crew of the shift rig, as well as their residence near the place of work. Currently, drilling operations are carried out intensively in a short time. This design is applicable for the deployment of headquarters during exercises, the creation of mobile medical units, such as field surgery, etc.
