Description

Vibration box self-lubricating system for construction pile driving machine

This invention relates to a self-lubricating system, especially a vibration box self-lubricating system for a construction pile driver.

According to general construction and civil engineering excavation operations, piles are usually driven to an appropriate depth and connected with each other to surround the area to be excavated, and then the excavation is carried out. This can prevent the soil around the excavation area from collapsing. , and may cause cracks in the walls of neighboring houses or damage to the foundation. Piling projects generally use a vibration pile driver installed on an excavator, and the vibration pile driver is used to clamp the pile body, using the weight of the pile body and the vibration of the pile driver. Function to carry out piling operations.

A conventional vibrating pile driver structure includes a hanger with two cantilever arms. A pivot base is pivoted between the two cantilever arms. The pivot base is combined with and fixed a vibration box at the bottom that can be equipped with a chuck. There is a chamber inside the vibration box, and there is a resonance device driven by a hydraulic motor to form a resonance in the chamber, so that the pile body clamped by the chuck at the bottom of the vibration box can be vibrated and driven into the ground.

When the conventional vibration pile driving machine is used, it generates vibrations in the form of rotation by deflecting the center of gravity of the block, thereby providing the kinetic energy of the vibration during pile driving. In addition, the axis used for rotation in the vibration device is due to the use of During the rotation of the yaw center of gravity, the rotational friction caused by high momentum is more likely to generate waste heat. Therefore, lubricating oil is added to the space where the parts are placed internally and soaked in it, which produces heat dissipation and lubrication functions. The lubricating oil in the vibration device is Mainly half full can prevent overflow of lubricating oil and reduce the impact of resistance caused by the fluid of lubricating oil.

Therefore, the industry has developed a vibration box self-lubricating system, as shown in the patent announcement No. M586733 "Drumming machine lubrication structure". When it is used, the vibration wheel can be used to drive the gear plate. The lubricating oil is filled with the perforations of the partitions, and allows the lubricating oil to flow into the lubricating oil space, and a predetermined amount of lubricating oil is accommodated through the inclined height of each partition. The excess lubricating oil can flow back to the lower chamber through each perforation. A space is provided to maintain the amount of lubricating oil in the accommodation space and the lubricating oil space. The lubricating oil in the lubricating oil space flows through each diversion opening to the lubricating oil port of each bearing seat, and is directed to the bearing for lubrication. and cooling.

However, although this conventional vibration box self-lubricating system can pump lubricating oil into the perforations of the partition and then guide the lubricating oil to the bearings for lubrication and cooling, the lubricating oil is guided to the bearings by gravity. Therefore, the flow rate of lubricating oil is slow. When the lubricating oil is directed to the bearing, it can only flow through the bearing surface and cannot enter the inside of the bearing for lubrication and cooling. As a result, the bearing is still easily damaged and stuck due to high temperature and thermal expansion caused by insufficient lubrication. Shortening the service life of bearings and increasing the frequency of bearing replacements will cause considerable trouble to users and increase bearing purchase and replacement costs.

In view of the above-mentioned shortcomings of the conventional vibration box self-lubricating system, the creator thought about the idea of creation. After many discussions, trial sample testing, and many corrections and improvements, he came up with this creation.

This invention provides a self-lubricating system for the vibration box of a construction pile driver, which includes: a vibration box with a storage space inside to accommodate lubricating oil. The vibration box is provided with two groups of zones; The eccentric shaft group is respectively provided with a driving shaft and a driven shaft. The driving shaft and the driven shaft The shafts are respectively installed in the two sets of areas, and a gear is set on each of the driving shaft and the driven shaft, and the gears set on the driving shaft and the driven shaft mesh with each other, and the driving shaft and the driven shaft are meshed with each other. A counterweight block is assembled on both sides of the gear on the moving shaft. Each counterweight block is provided with an arc-shaped groove on the side away from the gear. An oil guide plate is provided on each arc-shaped groove. , the middle part of each oil guide plate is respectively provided with a positioning pin inserted into the arc-shaped groove, so that a clockwise oil path and a counterclockwise oil path are formed between each arc-shaped groove and each oil guide plate. The clockwise oil circuit has a clockwise oil inlet, the counterclockwise oil circuit has a counterclockwise oil inlet, the clockwise oil circuit and the counterclockwise oil circuit are separated by the positioning pin, each The oil guide plate is provided near the middle with a first oil injection port communicating with the clockwise oil circuit and a second oil injection port communicating with the counterclockwise oil circuit; a plurality of bearings are sleeved on the driving shaft and the The two ends of the driven shaft are adjacent to each other on the outside of the counterweight block, and the plurality of bearings are respectively accommodated in two cover units. The two cover units are fixed on opposite sides of the vibration box, and the two cover units are fixed on opposite sides of the vibration box. The accommodation space of the vibration box is closed; and a motor is arranged on one of the two capping units and is connected to the driving shaft to provide power to drive the driving shaft to rotate.

The main purpose of the vibration box self-lubricating system of this construction pile driver is that when it is used, the lubricating oil can flow into the clockwise oil circuit or the counterclockwise oil circuit through the rotation speed of the counterweight block, and then the lubricating oil can flow into the clockwise oil circuit or the counterclockwise oil circuit through the first nozzle. The oil port or the second oil injection port sprays towards the inside of the bearing, so that the lubricating oil fully contacts the inside of the bearing, thereby improving lubrication and cooling and improving the heat exchange efficiency, avoiding damage to the bearing due to high temperature and thermal expansion caused by insufficient lubrication.
