The device is mainly characterized in that a plurality of hundred-ton jacks or cranes are used for jacking or lifting heavy objects to press the timber pressing die for a long time, the timber which is boiled for a long time by chemical drugs and kept constant temperature for a long time can be compressed into steel-iron hard timber, and the device is suitable for professional popularization and use in the timber industry.)

1. The first scheme of the gravity compression wood hardening device is characterized in that: the method comprises the steps of utilizing a large movable crane or a movable crane commonly used in factories as a hoisting tool, then casting a high-pressure-resistant reinforced concrete platform on the ground in situ, manufacturing steel moulds for pressing plates, square materials and round and square wood by using steel plates, welding a plurality of square or cylindrical box barrels for containing gravel liquid, or directly pouring concrete into the box barrels to manufacture a plurality of concrete square and round block columns of ten to fifty tons for hoisting on a wood pressing production platform to press hard wood.

2. The second scheme of the gravity compression wood hardening device is characterized in that: a steel plate platform with the height of 80 cm below is arranged on the ground of a production field and is used as a production platform for pressing timber, a steel plate with the four sides 20 cm larger than the platform and the thickness of 3-15 cm is arranged on the platform, and a plurality of concrete blocks with the weight of 100 and 1000 tons or boxes and barrels for containing heavy objects are arranged on the steel plate surface; a wood pressing steel die is arranged on the platform surface below the steel plate, and soft wood specification plates which need to be pressed and are soaked and boiled for a period of time by chemical medicines are arranged in the pressing steel die; four to twenty hundred-ton hydraulic jacks are arranged on four sides of the steel plate; the steel mould is used for jacking steel plates to load and unload steel mould wood to be pressed.

The technical field is as follows: the invention relates to a gravity compression wood hardening device, belonging to the field of wood processing equipment.

Background art: what is not done is that wood, especially soft wood, is not firm enough in daily use and is not pressure-resistant and durable for use as furniture or the like? The present invention is a solution to this dilemma!

The invention content is as follows: how good can it be to make soft, non-pressure-resistant and durable wood become hard, pressure-resistant and durable? Is that! According to the research at home and abroad, the soft wood can be boiled and soaked for a period of time by the chemical medicament treatment liquid, and can be changed into the wood with the same hardness as steel after heat preservation and pressure maintaining for a period of time; but do such devices currently supply utility to maintain high pressure for a period of time? Not! What is about a reason that only instant plate presses, i.e., hydraulic plate presses, a one-ton plate press needs 50 ten thousand, and the purpose of maintaining constant pressure for a long period of time cannot be achieved? The invention can be realized only by combining a long-arm crane or a crane with a plurality of concrete blocks or containers loaded with gravel water, and forming a set of production device by combining main components such as a platform for producing pressed wood, a device for heating and maintaining constant temperature and the like.

The specific implementation mode is as follows: for the purpose of the invention, there are two embodiments, the first is characterized in that: the method comprises the steps of utilizing a large movable crane or a movable crane commonly used in factories as a hoisting tool, then casting a high-pressure-resistant reinforced concrete platform on the ground in situ, manufacturing steel moulds for pressing plates, square materials and round and square wood by using steel plates, welding a plurality of square or cylindrical box barrels for containing gravel liquid, or directly pouring concrete into the box barrels to manufacture a plurality of concrete square and round block columns of ten to fifty tons for hoisting on a wood pressing production platform to press hard wood.

The working principle is as follows: the working principle of the scheme is as follows: putting wood boards or square materials or cylindrical wood sections and the like which need to be pressed and are boiled by chemical liquid into a pressing die, after a pressing production platform is installed, starting a crane to stack the boxes or concrete block columns filled with gravel liquid onto a pressing plate of the wood die one by one, stopping hoisting when the required total pressure tonnage is reached, hoisting the boxes or concrete block columns off the platform one by one after a preset pressing time period is maintained, taking out the pressed wood, reloading a new batch of die materials which need to be pressed, and repeating the working process again until the task is finished.

The second scheme is characterized in that: a steel plate platform with the height of 80 cm below is arranged on the ground of a production field and is used as a production platform for pressing timber, a steel plate with the four sides 20 cm larger than the platform and the thickness of 3-15 cm is arranged on the platform, and a plurality of concrete blocks with the weight of 100 and 1000 tons or boxes and barrels for containing heavy objects are arranged on the steel plate surface; the steel plate is placed on the bottom platform surface of the wood pressing steel die, and the soft wood specification plate which is required to be pressed and is soaked and boiled for a period of time by chemical medicines is arranged in the pressing steel die. Four to twenty hundred-ton hydraulic jacks are arranged on four sides of the steel plate. The steel mould is used for jacking steel plates to load and unload steel mould wood to be pressed.

The working principle is as follows: the working principle of the second scheme is as follows: the working personnel firstly load the wood to be pressed into the steel mould, after the heavy object above the steel plate is pre-lifted by the operation of the jack to reach the preset height, the steel mould wood to be pressed is loaded onto the platform, then the jack is released to press the kiloton heavy object above the steel plate on the steel mould wood, after the required time period is maintained, the jack is operated to lift the heavy object above the steel plate, the heavy object is taken out, the qualified steel mould wood is pressed, the working process is repeated again until the production task is completed.

The positive effects are as follows: the invention adopts a simple method to realize the purpose of complex machine pressing, saves a large amount of initial investment, is a preferred practical technical device for initial enterprises, and is worth popularizing and applying.
