The utility model discloses a guide rail lubricating device and magnetic drive conveying line, wherein the guide rail lubricating device includes oil storage tank, piston and piston rod, the piston is located in the oil storage tank and divides the oil storage tank into first chamber and second chamber, the first chamber is used for storing lubricating grease, the oil storage tank has the oil outlet that communicates with the first chamber, and the oil outlet is used for communicating with the inner chamber of guide rail through pipeline, one end of piston rod is connected with the piston, the other end of piston rod is equipped with trigger part, and piston rod passes through second chamber to make trigger part be located outside the oil storage tank. When the utility model guide rail lubricating device is applied to the magnetic drive conveying line, trigger part accepts the contact drive of mover, and drives piston rod and piston to move to the direction close to the oil outlet to supply oil to the guide rail. The supply of lubricating grease strictly follows the movement rhythm of mover, and high frequency trace oil injection guarantees the continuity of guide rail whole section oil film, avoids long distance end dry grinding, and prevents the pollution problem caused by excessive lubrication simultaneously.

The utility model discloses a kind of axle sleeve of electric wheel type loader working device, belong to electric loader technical field. Including: first axle sleeve, second axle sleeve and third axle sleeve connected on swing arm are connected on movable arm;First oil feeding cavity and multiple groups of first annular grooves are opened on the first axle sleeve, and the first oil feeding cavity is communicated with first annular groove;First pin shaft is connected in the first axle sleeve;When the first oil feeding cavity sends in butter to middle first annular groove, butter flows to the first annular groove of both sides through the gap between first axle sleeve and first pin shaft;By setting multiple annular grooves in first axle sleeve, second axle sleeve, third axle sleeve respectively, replace traditional single annular groove structure, significantly increase the storage capacity of butter in axle sleeve, effectively avoid dry grinding phenomenon, reduce the incidence of pin shaft and axle sleeve abnormal wear, abnormal sound, fracture and other faults, prolong the maintenance cycle and service life of working device, improve the operation stability of loader.

The invention belongs to the technical field of ground grinding machines, and particularly relates to a ground grinding machine for indoor construction, which comprises an extrusion type water spraying assembly, a periodic pressure applying assembly, a grinding shell assembly, a planetary grinding assembly, an advancing assembly and a rack assembly, the periodic pressure applying assemblies are annularly and evenly distributed on the planetary grinding assembly, the planetary grinding assembly is rotationally arranged in the grinding shell assembly, and the advancing assembly is arranged below the rack assembly. Through periodical rotation of the planet carrier, the extrusion piston can be periodically pressed in a reciprocating mode in cooperation with the annularly-distributed slope tables, and the technical purpose of reciprocating water spraying can be achieved in cooperation with the one-way valve and the annularly-arranged spray head; compared with direct water supply through the water tank, the pressure fluctuation caused by the change of the residual water in the water tank can be eliminated, and the technical effect of maintaining the stable water supply can be achieved no matter how the residual water in the water tank is.

The utility model relates to a detection device for diesel engine counterweight adjustment belongs to the technical field of crankshaft counterweight detection, the detection device for diesel engine counterweight adjustment, include: set up in the clamping plate of dynamic balance testing machine detection platform, the recess is established in the top of clamping plate, auxiliary assembly, auxiliary assembly sets up in the recess of clamping plate, wherein, clamping assembly includes setting up in the fin of clamping plate, the one side of fin is provided with guide plate, through setting up the fin of auxiliary assembly, can when the high -speed rotation of crankshaft, the heat of lubricating oil inside auxiliary shell is continuously discharged outward, to the heat of lubricating oil and outside each other exchange, reach the heat dissipation of lubricating oil, prevent the problem of high temperature and cause lubricating oil carbonization to occur, through setting up guide plate, and the guide plate is cotton board, can when the auxiliary shell cooperation heat insulating ring holds the limit of crankshaft neck, continuously supplies the oil for the crankshaft neck to keep lubrication, prevents the dry grinding phenomenon.
