Abstract

This utility model discloses a self-lubricating mechanism driven by a mechanical grab bucket pulley, including a grab bucket pulley, an oil pump, and a corrugated plate located on one side of the pulley and rotating with it. The oil pump includes an oil storage tank, a self-lubricating piston cylinder communicating with the oil storage tank, and a piston rod. One end of the cylinder has an oil outlet, which is connected to various oiling points on the grab bucket via a pipeline and a distributor. A return spring is fitted on the extended end of the piston rod. The corrugated plate has concave and convex arc surfaces that abut against the extended end of the piston rod. The pulley drives the corrugated plate to rotate, causing the piston rod to extend and retract, thereby squeezing the lubricating oil from the self-lubricating piston cylinder and outputting it from the oil outlet to each oiling point. When the mechanical grab bucket stops running, the pulley and corrugated plate also stop rotating, thus stopping the lubrication operation of the piston rod of the oil pump.

Description

Self-lubricating mechanism driven by mechanical grab pulley

Technical Field

The utility model belongs to a mechanical grab, and particularly relates to a self-lubricating mechanism driven by a mechanical grab pulley.

Background

Because the mechanical grab bucket with the pulley needs more lubricated pin shafts and bearings, manual maintenance is inconvenient, and climbing operation is needed, the safety risk is higher.

Currently, existing automatic lubrication systems in the market are generally electric drive type, and a battery is required to be installed for driving. Therefore, the pump of the electric drive type automatic lubrication system has the problems that the oil supply is not stopped by the automatic lubrication pump as long as the battery is still powered, the electric quantity of the battery is fast to consume, the battery is required to be replaced frequently, the operation is complex and the like.

Disclosure of utility model

The utility model aims to solve the technical problem of providing a self-lubricating mechanism driven by a mechanical grab pulley, wherein a lubricating pump of the self-lubricating mechanism adopts a mechanical self-lubricating structure and can be used for oiling along with the rotation of the pulley, and the pulley does not need to be oiled when not working.

In order to solve the technical problems, the utility model adopts the following technical scheme:

The utility model provides a mechanical grab pulley driven self-lubricating mechanism, includes grab pulley, locates the charge pump in the pulley outside, still including locating pulley one side and along with the wave board of pulley pivoted together, the charge pump includes the oil storage tank, with oil storage tank communicating self-lubricating piston cylinder body and piston rod, cylinder body one end has the oil-out, the oil-out is connected to each oil filler point of grab through pipeline and distributor, the cover is equipped with reset spring on the piston rod stretches out the end, has the unsmooth cambered surface that can offset with the piston rod stretches out end tip on the wave board.

The self-lubricating piston cylinder body is arranged at the lower part of the oil storage tank and is mutually communicated.

And the self-lubricating piston cylinder body is also provided with a lubricating oil filling port.

The oil filling pump is arranged on the outer side of the pulley seat of the pulley.

The self-lubricating mechanism driven by the mechanical grab pulley is changed into a mechanical energy supply structure, namely, the pulley drives the wave plate to rotate, so that the piston rod stretches and contracts, lubricating oil of the self-lubricating piston cylinder body is extruded, and the lubricating oil is output to each oiling point through the oil outlet. When the mechanical grab stops running, the pulley and the wave plate also stop rotating along with the mechanical grab, so that the piston rod of the oil filling pump stops lubricating operation. The battery does not need to be replaced, and the frequency of manual maintenance is reduced.

Detailed Description

The self-lubricating mechanism driven by the mechanical grab pulley is shown in fig. 1-9, and comprises a grab pulley 1 and an oil filling pump 2 arranged on the outer side of the pulley 1, and compared with the prior art, the self-lubricating mechanism is characterized by further comprising a wave plate 3 arranged on one side of the pulley 1 and rotating along with the pulley 1, and the oil filling pump 2 is driven mechanically instead. The oil pump 2 is arranged on the outer side of the grab bucket lower bolster pulley 1 seat, and specifically comprises an oil storage tank 4, a self-lubricating piston cylinder body 5 and a piston rod 6, wherein the self-lubricating piston cylinder body 5 is communicated with the oil storage tank 4. The self-lubricating piston cylinder 5 is arranged at the lower part of the oil storage tank 4 and communicated with each other, and receives lubricating oil flowing out of the oil storage tank 4 into the cylinder 5. One end of the cylinder body 5 is provided with an oil outlet 7, and the oil outlet 7 is connected to each oiling point of the grab bucket through a pipeline 8 and a distributor 9, and specifically comprises an upper supporting rod pin oiling point 10a, an upper pulley shaft oiling point 10b, a lower pulley shaft oiling point 10c, a main pin oiling point 10d and a lower supporting rod pin oiling point 10e. The self-lubricating piston cylinder 5 is also provided with a lubricating oil filling port 11 which is positioned at one side of the lower part of the cylinder 5 and is connected with the cylinder 5 and the oil storage tank 4 for supplementing lubricating oil. One end of the piston rod 6 is arranged in the cylinder body 5, the other end extends out of the cylinder body 5, and a return spring 12 is sleeved on the extending end. The wave plate 3 is provided with a continuously and uniformly undulating concave-convex cambered surface, and can be propped against the end part of the extending end of the piston rod 6. The design of the concave-convex cambered surface can form wave crests and wave troughs with fixed frequency.

The working principle of the self-lubricating mechanism of the utility model is as follows:

When the grab bucket runs, the pulley 1 rotates, the wave plate 3 rotates along with the pulley, the convex surface of the wave plate pushes the plug rod to squeeze into the cylinder body 5 when passing (namely, the wave crest), and the concave surface drives the piston rod 6 to reset by the reset spring 12 when passing (namely, the wave trough). The reciprocating motion can force the lubricating oil in the cylinder body 5 to be output from the oil outlet 7 and enter a pipeline 8 and a distributor 9 which are arranged on the grab bucket, so as to finish the oiling process to each lubricating point. When the grab stops running, the pulley 1 and the wave plate 3 also stop rotating, so that the piston rod 6 of the oil filling pump 2 stops lubricating operation.

It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for the purpose of limiting the utility model, and that variations and modifications of the above described embodiments will fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
