Abstract

A mobile double-drum winch designed for approaching loads by means of a rope wound onto drums that are adapted for off-road driving, so that they simultaneously form wheels on which the winch is able to change working positions using its own drive. For this purpose, two pins carrying cantilevered drums are mounted coaxially in the central part of the winch frame. The drive of the right and left drums, passing through hollow pins, is mutually independent and can be switched off as needed. This allows the winch to have good maneuverability and mobility in the terrain during transfers, as well as a cable system for approaching loads. The mechanism can be used in forestry, agriculture and construction.

Description

241S77

The present invention provides a mobile two-drum retractor designed for approaching loads. Self-propelled winches are known which have a drive motor, but a drive drive and a winch drive, and separate units. The disadvantage of such a solution is the complexity of the drive. the result of branching, more complicated control and increased weight of the entire apparatus. a self-propelled AO225 883 self-propelled reel is also known, the directional steering of which is provided by the servicing of its own nylon during travel, and can cause problems for heavier winches and when driving in inclined hazardous situations. One drum does not allow the ropeway approach system and forces the operator to return to the end of the rope every time the load approaches. This increases the operator's physical burden.

The above-mentioned drawbacks are eliminated by the traveling double-drum winch according to the invention, which consists in that in the middle part of the frame it is mounted on this frame and mutually co-axial hollow hollows through which the drive of the right-hand drum passes, and the two drives are disengaged and mutually independent. The navi-motor mounted on the swiveling bracket is a position-adjustable pull-out length anchored in the winch frame.

The main advantage of the mobile double-drum winch according to the invention is the simplification of the control, the reduction of the physical and psychological effort of the operator, the reduction of the weight of the whole device, the possibility of the remote control of the travel and the winding without the direct contact of the operator with the device, while the simplicity of the whole drive and technological advantages of a two-drum winch are retouched.

The accompanying drawings illustrate a traveling double drum winch according to the invention and its functional parts. Figure 1 is a side elevational view. FIG. 2 is a top plan view of FIG.

The mobile double drum winch according to the invention (Fig. 1, Fig. 2) consists of a frame 1, the front part of which is a support 2 serving to stabilize the winch in the field in the winding, the rear part carrying directional pulleys 3 intended for guiding the rope and handle 5 for winches at work.

In order to allow the rear part of the spider frame to be landed on the ground, it is supported by a trailing wheel 4 which is free to rotate and allows the winch to rotate in place. perpendicular to this frame and two hollow pins 6 mutually coaxially mounted in a co-axial direction 10. The right-hand drum drive and the center of the left hollow drum pass through the center of the right-hand pivot. Both are independent of each other. If desired, the different speed or direction of rotation of the right-hand drum and the right-hand wheel connected thereto, relative to the left drum and the associated Tavemukoles, is possible. When traveling, this will result in a turnable winch on the side of the slower wheel. When the spins are turned in opposite directions, the drums are reeled as a whole shaft of its own vertical axis. In this case, the rope is unwound from one drum to the other in the case of the n-winding, and the rope is wound up and approaching the shore. This allows the cable way to winch the winch.

The winch drive motor 7 is fastened to the bracket 8 pivoting in the upright plane of the longitudinal axis of the winch. The position of the engine, the desire for proper operation even when the winding or slope is running, is adjusted by changing the length of the rod 9 defining the inclination of the motor bracket relative to the frame.

After tilting the winch into the working position, where it rests on the support of the frame front and the running wheels are not in contact with the terrain, the winch rest against the tree or buckling anchor. For heavier hitch, its tilting to the working position is achieved by sliding the strut out of the frame. After anchoring the winch in growth (Fig. 3) and pulling the ropes from the drum over the directional pulley to the approach point, the winch is capable of attracting loads.

The mobile double drum winch according to the invention has, in the subsequent suitable decomposition, good stability during rolling, which is an additional condition for remote control, whereby the operator does not have direct contact with the device. The independent movement of the drums allows one-way adjustment of the wheeled navi-ya to the track, which makes it possible to use the device even in difficult terrain. The positioning adjustable motor guarantees reliable operation even at considerable lateral slopes. Moving the engine changes the position of the center of gravity of the winch, which improves its stability on slopes. Z "i.
