Abstract

This invention relates to vehicles for the transport of long loads, such as wood, on ice. The purpose of the invention is to improve performance by redistributing the loads on the chassis when operating on ice. The vehicle for the transport of long goods contains a self-propelled chassis with front and rear wheeled carts. The chassis 1 is fixed on the chassis frame 3. A hinged jaw with a lower jaw 5 is attached to the hinge so that it can be rotated in the plane of the jig 1. There are hydraulic cylinders 4 and 8 of the sleeves of the I-turn and gripper. The wheels of the rear carriage are hinged on ras. 3 with the possibility of their raising relative to it by additional hydrocyliders 14. The grip on the lower surface of the jaw 5 is equipped with skids 11.1 Cp. f-ly. 4 il. со со со ОГ) СП

Description

The invention relates to means of mechanization of loading and unloading and transport operations with lengthy goods, mainly timber, and can be used in the forest industry.

The aim of the invention is to improve the performance by redistributing the loads on the chassis when operating on ice.

FIG. 1 schematically shows a vehicle for the transport of long loads in the initial position, a general view; in fig. 2 - the same, in the transport position when installing the jaw grip on the frame of the self-propelled chassis; in fig. 3 - the same, when transporting timber over ice; in fig. 4 - the same, at the time of unloading timber on ice.

A vehicle for the transport of long loads includes a pivot bearing 1 mounted on axis 2, which is located on the frame 3 of the self-propelled chassis and can be rotated relative to it in the longitudinal vertical plane by the hydraulic cylinder 4.

Jaw grip contains the lower 5 and upper jaw b. The lower jaw 5 is mounted on an axis 7 located on the rotary support 1, and can be rotated relative to it by the hydraulic cylinders 8 in the longitudinal vertical plane. The upper jaws 6 are mounted on an axis 9 located at the upper end of the lower jaw 5 and can be rotated relative to it in the longitudinal vertical plane by hydraulic cylinders 10. The jaw grip is equipped with runners 11, which are elements of the running equipment of the type described when the vehicle is moving over ice in the water area. The skid 11 is installed on the lower jaw 5. The maxillary grip is made with flexible (cable or chain) elements 12, fixed at one end on the lower jaw 5, and the other on the upper jaw 6. The flexible elements 12 are designed to force the load out of the maxillary grip when unload it.

The running wheels 13 of the rear wheeled cart of the self-propelled chassis are hinged to the frame 3 and are mounted so as to be raised relative to the frame 3 by rotation through additional hydraulic cylinders 14 relative to the axis 15 located on the frame 3, which is associated with the front wheel cart 16.

Vehicle for transportation of long goods in the summer period works as follows.

With the deflected rotary support 1 back along the vehicle and the raised upper jaw x 6 in reverse self-propelled chassis, the lower ends of the lower jaw 5 are brought under the package (stack) of timber 17. Upper jaws

a packet of forest matrices is clamped in the maxillary grip. At the same time, the flexible elements are deflected by the timber package and cover it. Bearing 1 is turning

together with the maxillary grip and timber package counterclockwise around axis 2 by the hydraulic cylinder 4 and is set in the upper transport position. In this position, the vehicle moves to the place of unloading.

For unloading, the support 1 is rotated together with the maxillary grip and the timber package by the hydraulic cylinder 4 back along the vehicle (clockwise

5 arrow in FIG. four). After the support 1 is rotated to the required angle, the jaw grip is rotated by hydraulic cylinders 8 around the axis 7 in a clockwise direction and set to the desired position, the upper jaws 6 are opened and the timber package 17 is unloaded from the jaw grip. After unloading, the pivot bearing with the maxillary gripper is set to the upper transport position, the vehicle returns to the place of loading, and the cycle is repeated.

When transporting drvesiny in the water area in winter, the loaded vehicle drives up to the edge of the water area. On the ice pivot bearing 1 with maxillary

The Q is rotated in a clockwise direction from the upper transport position to the lower one so that the skid 11 lies on the supporting surface, i.e. ice. Then the wheels 13 of the rear wheeled cart of the self-propelled chassis are rotated with hydraulic cylinders 14 around the axis 15 and raised above the supporting surface. In this position, the vehicle is supported on the front wheel carriage 16 and the lower jaw 5 of the grip and moves across the ice of the water area to the place of laying.

0 wood.

The timber bundle 17 is unloaded from the jaw grip on ice by pushing it out of the lower jaw 5 by flexible elements 12 when the upper jaws 6 are opened (lifted). After unloading the package of timber, the vehicle returns to the place of loading and the cycle repeats.
