A lifting device that uses hydraulic rods to generate heat and automatically spray lubricating oil

Abstract

The invention relates to the technical field of lubricating oil spraying by a lifting mechanism. A lifting device that uses a hydraulic rod to generate heat to automatically spray lubricating oil includes a hydraulic rod. The side of the limit mechanism away from the oil storage tank is fixedly connected with a hollow channel, and the inside of the hollow channel is fixedly connected with an oil delivery pipe. The surface of the hollow channel is provided with an exhaust hole, and the upper part of the hollow channel is fixedly connected with a extrusion The extruding mechanism includes a housing, a piston is slidably connected to the inside of the housing, and the end of the piston away from the inner wall of the housing is movably connected to an oil injection hole through a piston rod. The lubricating oil is sucked into the oil injection port. When the piston moves down, the sucked lubricating oil will be sprayed out from the oil injection port because of the one-way flow valve, so that the lifting mechanism does not need to be stopped. Complete the effect of replenishing oil.

Description

technical field [0001] The invention relates to the technical field of lubricating oil spraying by a lifting mechanism, in particular to a lifting device that automatically sprays lubricating oil by using a hydraulic rod to generate heat during operation. Background technique [0002] On high-rise construction sites, construction hoists are usually installed. A general construction elevator is composed of several parts such as a car, a driving mechanism, a standard section, an attached wall, a chassis, a fence, and an electrical system. It is a relatively large construction machine that is attached to the main body of the building construction and uses the car (also known as the work cage) to move vertically (or tilted) up and down along the track mast to carry people and objects. The most popular is the hydraulic rod. [0003] In order to ensure the normal operation of the construction elevator, it is often necessary to refuel some internal mechanical parts. At present, t...

Problems solved by technology

[0003] In order to ensure the normal operation of the construction elevator, it is often necessary to refuel some internal mechanical parts. At present, there are two ways to refuel the lifting equipment. One is to manually apply lubricating oil or butter. Obviously, this The brushing efficiency is low, and the other is mechanical oil replenishment. Most mechanical oil replenishment equipment needs to be equipped with a special motor to drive the fuel injection pump to spray lubricating oil. The manufacturing cost of these special equipment is high and the structure is complicated.

[0004] Whether it is manual or mechanical oil replenishment, the oil replenishment can only be carried out after the lifting equipment stops working, and it takes a certain amount of time to complete the oil replenishment work, which will cause the construction to temporarily stop and affect its work efficiency. A lifting device that uses hydraulic rods to work and generate heat to automatically spray lubricating oil came into being
