Abstract

FIELD: forestry engineering. SUBSTANCE: gear for hoisting and transportation of the drowned wood has an access ramp made in the form of a ballasted transporter-pontoon whose hinged bore end is connected with an intermediate accumulator disposed in the pontoon. The stern end of the access ramp sunk into the water is equipped with a clamp - manipulator connected with an arresting device fixing the position of the mentioned end of the transporter-pontoon on the bottom of the basin. The moving belt of the transporter-pontoon is equipped along the whole length with rests, the distance between them is commensurable with the length of the drowned wood. A guiding chute with the opening bottom is mounted on the sunk fore end of the transporter-pontoon over the moving belt. EFFECT: improved cleaning of the bottom of rivers and basins. 1 cl, 2 dwg

Description

 The invention relates to the forestry industry and can be used to clean the bottom of rivers and ponds from sunken and flooded forests.

Currently, to clean up rivers and ponds of sunken wood in the forestry industry, mass-produced fuel-lifting units TAC-1M, T-2M, LS-41A are used with a cleaning depth of several meters and a capacity of up to 7000 m ³ per year. The basis of the design of these units is small-sitting dies with a displacement of 50 - 90 tons and excavator and crane devices installed on them with serial ground-based use. Moving the dashboards is carried out either by towing, or using their own propellers.

 However, these devices have a number of disadvantages, which are as follows: the technical means used do not allow cleaning the bottom of reservoirs at depths starting from 10 m or more; due to the lack of underwater surveillance equipment, the bottom is cleaned “blindly”, i.e. without the necessary full control of the degree of purification; low productivity of technical means of lifting sunken wood.

 A device for lifting sunken objects is also known, which is designed to lift sunken equipment from a shallow depth, mainly transport, and consists of a platform assembled from floating modules and having a central opening in which the ramp is pivotally mounted at one end.

 To raise the sunken object, the cable from the winch placed on the deck is thrown through the rollers on the ramps and hooked to the sunken object. When the cable is pulled, the ramp drops, and as the object rises, it rises. With the same cable, the sunken object is pulled onto the ramp along a sloping ramp.

 This device has the same disadvantages, and in addition, the need for a high-capacity traction winch; the rise of each sunken object separately determines the low performance of the system.

 The aim of the invention is to remedy these disadvantages, as well as improving the efficiency of operations to clean the bottom of water bodies from sunken wood.

 This is achieved by the fact that the device for lifting and transporting sunken wood containing a pontoon, to which a ramp is pivotally attached at one end, the other end of which is mounted for immersion in water, is equipped with a drive located on the pontoon, and the ramp contains a pontoon with a conveyor belt connected with a drive, and the end of the ramp immersed in water is made with a gripper-manipulator equipped with monitoring equipment underwater, a locking mechanism for fixing the position of the conveyor at the bottom of the water volume, while the conveyor belt is equipped with stops along the entire length, and a guide tray with a drop-down bottom and a wood cutting mechanism are installed on the immersed end of the conveyor.

 In FIG. 1 shows a complex for lifting and transporting sunken wood, general view; in FIG. 2 - the same, top view.

 A device for lifting and transporting sunken wood consists of a ramp 1, made in the form of a pontoon with a conveyor 5, placed by the nasal tip in the neckline of the pontoon 2 and pivotally connected with it. The pontoon 2 is equipped with an intermediate drive 3. Flooding of the aft end of the ramp is provided by ballast tanks 4. The moving conveyor belt is equipped with stops 6, one from the other, at a distance of 6-7 m from each other, which corresponds to the standard length of wood trunks flooded during alloying . At the immersed aft end of the ramp, a guide tray 7 with a drop-down bottom is installed above the conveyor belt, which ensures that the tree trunks hit the conveyor belt in a specific place, namely between two adjacent stops. In addition, the immersed end of the ramp is equipped with a gripper-manipulator 8 associated with search apparatus 9 for monitoring under water, for example, a sonar-sounding device. The position of the end of the ramp is fixed at the bottom of the reservoir by the locking mechanism 11.

 For cutting long trunks into standard segments, the aft end of the ramp is equipped with a mechanism 12 for cutting trunks.

 The rise of wood is as follows.

 Pontoon 2 with a ramp is towed to the place of work. Then, filling the tanks with water 4, the aft end of the ramp, which rotates around the hinge 13, is flooded and fixed with a stop mechanism. At the same time, the conveyor 5, placed on the ramp 1, is set in motion. The gripper-manipulator 8, equipped with search equipment 9, is sent to the place of wood accumulation, grabs the trunk 10 and transfers it to the tray 7. Having lowered the barrel into the tray, the capture is deployed for the next one, and from the opened bottom of the tray, the trunk laid in it falls onto the conveyor belt exactly between the stops, which prevent the trunk from sliding along the conveyor. The triggering of the tray and the movement of the tape are synchronized, which ensures accurate hit of trunks in the right place of the conveyor.

 The trunks supplied by the gripper - manipulator are continuously fed upward by the conveyor one by one and dumped into the intermediate stacker 3 of the pontoon 2. Then, as necessary, the wood from the stacker is loaded with cranes installed on a towing truck (not shown in the drawing) or on the pontoon itself, onto transport barges (on not shown).

 Having cleared the bottom in a given area of the reservoir, the pontoon with a ramp is towed to a new location.

 Thus, the invention allows: to clean the coastal strip of rivers and water bodies from the forest lying on it; to raise fireboxes with their continuous supply to the surface with a productivity of up to 30 m in 1 h; cut vertically standing trunks of flooded forest; clean the bottom of rivers and ponds at a depth of 0 to 30 m; to fully control the degree of bottom cleaning through the use of search equipment.

 The presence of a conveyor, special devices on the immersed aft end of the ramp, as well as the presence of a pontoon drive, can improve the efficiency of operations to clean the bottom of rivers and ponds from sunken wood.

 The design of the ramp allows you to install on the aft end any necessary set of actuators, the operation of which can be carried out using a sonar sound recorder.
