Description

(54) DEVICE FOR LOADING, UNLOADING AND TRANSPORTATION OF LONG-DIMENSIONAL LOADS The invention relates to lifting and transport machines and can be used in the timber and woodworking industry. A device for loading, unloading and transporting long loads is known, comprising a wagon coupled to a semi-trailer with a sliding gorge, conic, jaw jibs and outriggers mounted on the crawler and semi-trailer, each arrow being rotated around a horizontal axis by means of a hydraulic cylinder. , pivotally connected to the outrigger 1. However, in the known device, the boom elements, with a cantilever grip, are in the process of collecting, loading and unloading the packs bending and torsional moments, which leads to a decrease in the reliability of the device, as a result of which, the booms of this design require considerable reinforcement to avoid damage. When the boom is installed in a vertical (transport) position, it is difficult to catch and fix it, and fixing and unlocking is performed by a drive lock, which complicates the design and inconvenience in the operation of the device, and also leads to a decrease in reliability. The purpose of the invention is to reduce bending and eliminating torsional loads on boom elements, increasing the reliability of the device. The goal is achieved in that the device is equipped with a beam connecting both arrows and hingedly interacting with the last and maxillary grips, while the hinges of one jaw gripper and boom mounted on the semi-trailer are mounted on a carriage moving by means of rollers along the beam, and the booms themselves are telescopic with movable and fixed sections. In addition, in order to simplify the design and ensure automatic locking of the moving boom section in the transport position and unlocking it in the working position, the boom pivot axis can be shifted relative to the transverse axis of the device. FIG. 1 shows the proposed device, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. ; in fig. 6 - device, rear view; in fig. 7 is a kinematic diagram of the mechanism for expanding the base of the device. The device consists of a tacha 1, on which, by means of the universal joint 2, the frame 3 of the semi-trailer is fixed, in front of which there is a horseman in the form of a saddle 4 with a telescopic boom 5 and a shield 6 for trimming logs. A rear conic in the form of a saddle 7 with a telescopic boom 8 and a trimming shield, rigidly connected to the chassis 9 of the semi-trailer, freely moves on the rollers 10 along the frame guides 11 using the device base sliding mechanism. The spreading mechanism includes a power cylinder 12 connected by an eye to a semi-trailer frame and a rod to a moving axle 13 with three blocks (or asterisks) of a polyspast, the extreme 14 and 15 of which are stockpiled by traction ropes (or chains) 16 and 17, and the middle 18 is stockpiled by a rope (or chain) 19, passing through guide blocks 20 and 2. The arrows are connected by means of hinges 22 and 23 with a common beam 24, on which the jaws 25 and 26 are suspended, using hinges 27 and 28. All the hinges contain axles 29, providing rotation relative to the horizon oval axis. In the hinges 22, 27 and 28, the inner sleeve 30 with the beam 24 can be rotated relative to the longitudinal axis thereof in the support sleeve 31. The hinges 22 and 23 are made with turntables 32 mounted on the telescopic boom extendable sections, providing a turn about the vertical axis. The hinges 23 and 28 of the rear boom and the rear maxillary grip are mounted on the carriage 33 on the rollers 34, allowing free movement along the beam as the base of the device moves apart.

The boom can be rotated about axis 35 by hydraulic cylinder 36, also connected to outrigger 37.

The device works as follows.

The device is suitable for a drive or stack. The inclusion of hydraulic cylinders 36 lower outriggers. Retractable ones are raised, for example, by means of power cylinders, sections of telescopic booms, they are released without additional drive. The cylinders 36 are loaded onto boom elements, increasing the reliability of the device, it is equipped with a beam connecting both booms and hingedly interacting with the last and maxillary grips, while the joints of one jaw gripper and boom mounted on the semi-trailer are mounted on a carriage moving by rollers along the beams and the arrows themselves are made telescopic with movable and fixed sections.

2. The device according to claim 1, characterized in that, in order to simplify the design and provide for automatic fixation of the movable boom section in the transport position and unlocking in the working position, the boom pivot axis is displaced relative to the transverse axis of the device.

UT to retract the stem and lower the arrows 5 and 8 with jaw grips 25 and 26 over packs of long loads, in particular logs. They seize a stack of logs with them and, including the hydraulic cylinders 36 for pushing the rod out, lift the arrows, retract their movable sections and turn on the hydraulic cylinders 36 to retract the rods, raise the outriggers to the transport position. In this case, the arrows are fixed. The maxillary clamps, moving the pack of logs on conic 4 and 7, slightly open, include the hydraulic cylinder of the device base sliding mechanism, the landing gear 9 and the rear conic with boom. When this occurs, the alignment of the ends of the logs. The jaw grips are again compressed and the pack is wrapped using known devices. Claim 1.
