Oil temperature alarming star wheel external gearing four-division speed reducer of pile machine

Abstract

The invention relates to the technical field of pile machine speed reduction, in particular to an oil temperature alarming star wheel external gearing four-division speed reducer of a pile machine. The speed reducer comprises a box, motors, a cover plate and a transmission piece, and is characterized in that an oil temperature sensor is arranged in the box; a labyrinth vent hood is arranged on the cover plate; the two motors are inversely connected to the lower portion of the box, and the shaft extension ends of the motors are connected with star wheel speed reducers; the transmission piece comprises driving wheels, division gears and a center gear ring; the driving wheels are arranged on output shafts of the star wheel speed reducers; the division gears are symmetrically arranged on the two sides, division gear shafts are fixed to supporting plates, and the supporting plates are connected to the end faces of star wheel speed reducer shells; the center gear ring is connected with a flange of a main cylinder; the main cylinder is supported in the box through bearings; and the main cylinder is connected with a drill rod flange connected with a drill rod. The speed reducer has the beneficial effects that the dynamic conditions of the speed reducer can be mastered according to oil temperature changes; pressure of air in the box and pressure of air outside the box are balanced through the labyrinth vent hood; the tilting moment of the pile machine is reduced through the inverted motors, and the titling accident probability is lowered; and four-division bearing capacity is high, and inner gear ring hardening and tempering are easier and lower in cost than carburization.

Description

【Technical field】 [0001] The invention relates to the technical field of pile driver deceleration, and relates to an oil temperature alarm star wheel external meshing four-shunt pile driver reducer. 【Background technique】 [0002] With the rapid development of my country's economy, construction machinery has been widely used. As a basic construction, long screw pile machines are scattered all over the world, so that the demand for pile machines has increased sharply. Said: "There is even a phenomenon of queuing up to pick up the goods at the pile driver factory with a large amount of money. The three-ring reducer manufacturer that matches the power head with the pile driver factory has increased its output so that each pile driver manufacturer can supply a complete set Goods." (See Science and Fortune, 2013.01) [0003] Background technology: China Patent Office has published the following patents successively: [0004] (1) Power head of screw pile machine (201020300223.7) ...

AI Technical Summary

Problems solved by technology

The disadvantage of the ventilation hood (JB1130-70) is: the exhaust hole is too small (the maximum diameter of the straight hole in the box is only Φ20mm, and the small hole outside the box that is in contact with the environment is even smaller)

For the pile driver reducer, the disadvantages of the ventilation cover (JB1130-70) are even more obvious: open-air operation, large dust, and the small exhaust holes will gradually become smaller after the dust sees water, so that the ventilation cover will gradually lose the inside and outside of the box. Pressure balance, when the air pressure inside the box is greater than the air pressure outside the box, the lubricating oil will leak from the seal;

[0011] (c) Disadvantages of top-mounted dual motors: Due to the harsh working conditions on the construction site, most operators do not have maintenance equipment and skills. It is difficult to remove the heavy motor and reducer, so repair and maintenance are difficult, and the cap on the top of the motor is difficult to waterproof. more difficult to dust

[0012] (1) On April 26, 2006, a pile driver suddenly collapsed in a construction site on Xiangheyuan Road outside Dongzhimen, Beijing, causing the death of two workers
