Oil-temperature warning star-wheel two-way outputting pile machine speed reducer

Abstract

The invention relates to the technical field of pile machine speed reduction, and provides an oil-temperature warning star-wheel two-way outputting pile machine speed reducer. The oil-temperature warning star-wheel two-way outputting pile machine speed reducer comprises a case body, motors, a cover plate and a gear transmission part. The oil-temperature warning star-wheel two-way outputting pile machine speed reducer is characterized in that an oil temperature sensor is arranged in the case body, labyrinth type vent hoods are arranged on the cover plate, each labyrinth type vent hood comprises an outer shell, a labyrinth shell and an exhaust pipe, the motors are connected to the lower portion of the case body in an inverted mode, the drive ends of the motors are connected with star-wheel speed reducers, the gear transmission part comprises an external meshing pair and an internal meshing pair, the external meshing pair comprises driving wheels, diffluence gears and outer teeth of a center circle, the internal meshing pair comprises inner teeth of the center circle, five quasi planetary wheels and a center wheel, the center circle is connected with an outer sleeve which is supported in a center hole of the case body through bearings, the outer sleeve is connected with a base plate, and a base plate flange is used for being connected with a pile machine big casing; the center wheal is connected with an inner barrel which is supported in the outer sleeve through bearings, and the inner barrel is connected with a drill pipe sleeve. The oil-temperature warning star-wheel two-way outputting pile machine speed reducer has the advantages that the dynamic state of the speed reducer can be mastered, the air pressure inside and outside the case body is balanced, the tilting moment of the pile machine is reduced through the inverted motors, and the probability of tilting accidents is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of double-motor pile driver deceleration, and relates to an oil temperature alarm star wheel bidirectional output pile driver reducer. 【Background technique】 [0002] With the rapid development of my country's economy, construction machinery has been widely used, and the long screw pile machines used as infrastructure are scattered all over the world. As a result, 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) Background technique: [0003] (1) The invention patent of China Sunward Intelligent Equipment Co., Ltd. "Separate Drive Casing Auger Drilling Machi...

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;

[0012] (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, and the heavy motors and reducers are difficult to remove down, so it is difficult to repair and maintain, and the cap on the top of the motor is difficult to waterproof and even more difficult to prevent dust

[0013] (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
