Description

The solution relates to transport engineering, in particular to multi-purpose transport and technological means. The inventive transport and technological vehicle based on a self-propelled caterpillar chassis of an extremely small class solves the problem of small-scale mechanization of labor, in particular, it can be used to transport passengers and goods off-road, including virgin snow, wetlands, sands, and technological operations in agriculture and forestry, in construction and in other areas in which the use of large-sized transport and technological machines is impractical or impossible.

Known mini-timber carrier NNPI-1901 (Nizhny Novgorod scientific school of cross-country vehicles, transport and technological complexes and special equipment. Under the general editorship of professors V.V. Belyakov and A.P. Kulyashov. - Nizhny Novgorod: NSTU named after R.E. Alekseev , 2007.p.77). It has a housing, tracked undercarriage, engine, transmission. The machine is controlled by a drawbar located in front, which is affected by the operator-driver (the operator-driver is next to the mini-timber truck).

The main disadvantages of this machine are its narrow purpose and the fact that the operator controls while standing nearby, so the speed of movement is limited by the capabilities of the operator.

Known mini-skidder NSTU-1903 (Nizhny Novgorod Scientific School of all-terrain vehicles, transport and technological complexes and special equipment. Under the general editorship of professors V.V. Belyakov and A.P. Kulyashov. - Nizhny Novgorod: NSTU named after R.E. Alekseev , 2007.S. 78). It has a housing, tracked undercarriage, engine, transmission. Equipped with skid shield, mechanical winch. The machine is controlled by means of control levers, which are affected by the operator-driver.

The main disadvantages of this machine are its narrow purpose, namely, the use as a skidder.

As a prototype, a tracked vehicle for transporting goods was adopted (patent No. 2131817, V62D 51/04, V62D 55/00, published on 06/20/1999).

This vehicle can be controlled in two ways: by a standing and sitting operator.

The machine consists of a body on which the engine is mounted, a transmission consisting of stepless speed control mechanisms and a step-gear box. The stepless speed control mechanism connects the output shaft of the engine with the input shaft of the gearbox and can be made in the form of a variator, torque converter or hydraulic clutch.

The gearbox is made dual-band, has two speeds of movement: forward and backward. The gearbox also has a power take-off shaft for attachments and a winch drive. The undercarriage system consists of two rubber-fabric tracked contours and rubberized road wheels. The drive wheels are connected to the output shaft of the gearbox through a differential that distributes engine torque between the drive wheels. On the drive shafts of the right and left tracks mounted brake elements. It can be brake cones or discs. The movement of the machine is controlled using an external drawbar. The drawbar is made in the form of an articulated multi-link, folding in a vertical plane. This allows you to fold it in such a way that the operator has the ability to control the machine from a seat mounted on the machine. The seat is folding. The seat frame is mounted on the fence.

To implement the rotation of the machine drawbar is connected with its body by a vertical axis with the possibility of rotation around it. A link is connected to the axis, which acts through the leash on the brake elements. When turning the drawbar around the axis in one direction or another, the tracks of the corresponding side are braked. Depending on the force preloaded by the brake elements, the machine is rotated with different turning radii. On the drawbar there are: a gas lever, which is connected by a cable to a carburetor and an emergency stop lever for a machine, which is connected by a cable to a draft and then acts on the brake elements of both tracks simultaneously through a leash.

For skidding of logs, a swivel conic is provided. Timber can be loaded with a winch. The hitching equipment is connected to the machine with a hitch mounted on the swivel cone, and the attachment (plow, cultivator, etc.) is connected with a hitch mounted on the stern of the machine.

The disadvantage of this machine is that the place of the operator-driver is made behind the engine above the rotary cones, while the machine cannot be used as a skidder, which reduces its functionality. The absence of a safety shield increases the safety of the vehicle when it rolls over.

In addition, a hitch for trailed and mounted equipment is constantly installed, which is impractical; it must be made removable so that it does not interfere when performing work in which it is not used.

The performance and safety features of this machine can be improved.

The problem to be solved is the improvement of the design of transport and technological multi-purpose vehicles on the basis of a self-propelled tracked chassis in excess of a small class.

The technical result is the expansion of the functionality of the vehicle and increased safety.

This technical result is achieved by the fact that on a vehicle based on a self-propelled caterpillar chassis of an extra small class, comprising a housing, a running system, an engine, a transmission with a gearbox, an external drawbar for controlling the movement of the vehicle, an operator seat with a guard is mounted on the housing , means for connecting trailers and attachments, including at least a swivel cone and a hitch, the seat is mounted above the engine, in front of the seat no additional fence is used, and behind the seat there is a safety shield with an arcuate upper part, a winch is installed on the rear wall of the fence behind the seat, the hitch is removable; removable skid plate is installed on the body.

Installing the driver's seat in the front of the machine above the engine improves the weight distribution of the machine and increases its functionality, that is, additional space for cargo is freed up in comparison with the prototype.

The installation of a guard in front of the seat and a safety shield increases the safety of the vehicle, including during a rollover.

The installation of a removable hitch for attachments and trailers and a winch on the rear element of the fence and a removable skid plate expands the functionality of the machine.

The proposed transportation technology based on a self-propelled tracked chassis in excess of a small class is shown in the drawings:

figure 1 is a General view with a removable skid plate and in the working position of the drawbar when the operator is next, figure 2 is a General view with attachments and in the working position of the drawbar when the operator is sitting.

It contains a housing 1, a running system 2 including two rubber-fabric tracked contours and rubberized track rollers, drive wheels connected to the output shaft of the gearbox through a differential that distributes engine torque between the drive wheels, brake elements are installed on the drive shafts of the right and left tracks, which can be made in the form of brake cones or discs; engine 3, transmission 4 with gearbox, drawbar 5 for controlling vehicle movement. On the body above the engine, a seat 6 for the operator is installed. In front of the seat there is an additional guard 7, and behind the seat there is a guard with a safety shield 8 with an arcuate upper part. A winch 9 is installed on the rear wall of the fence. Means for connecting the trailed 10 and mounted equipment 11 include at least a swivel conic 12 and a removable coupling device 13, which may include a removable skid plate 14 mounted on the housing.

Transport and technological means on the basis of a self-propelled caterpillar chassis in excess of a small class works as follows.

When you turn on the engine 3, the operator-driver acts on the controls on the external drawbar 5, the engine speed increases and the torque is transmitted through the transmission 4 with the gearbox to the driving wheels of the running system 2 of the vehicle, which receives loads during movement.

The movement of the vehicle is possible when the operator-driver is in front of the vehicle and when sitting on the seat 6, the weight distribution improves, the space behind the engine remains unoccupied and various equipment can be located there. The operator’s legs are protected by a guard 7 from bumps and collisions with various obstacles. When tipping the machine, the operator is protected by a guard and safety shield 8 with an arcuate upper part installed behind the seat.

If necessary, skidding of logs on the vehicle is installed skidder 14, for their transportation are installed swivel cones 12 and additional trailed or mounted equipment 10 and 11, connected via a removable coupling device 13.

Loading of timber or transported goods is carried out using a winch 9.

The proposed transport and technological vehicle based on a self-propelled caterpillar chassis in excess of a small class has a good cross, reliable, environmentally friendly and functional.
