Description

Jacking equipment capable of uniformly coating grease Technical Field The invention relates to the technical field of jacking equipment, in particular to jacking equipment capable of uniformly coating grease. Background The jacking equipment is widely applied in the mechanical industry, and has the function of supporting a mechanism to be jacked so as to form a certain operation space below the mechanism to be jacked. For example, in the transportation industry, vehicles are regularly serviced. When the transportation vehicle enters a workshop for maintenance, the vehicle body is supported by the vehicle lifting machine so as to carry out maintenance operation on the locomotive vehicle. The car lifting jack comprises a vertically arranged screw rod and a nut sleeved on the screw rod, and a bracket is connected to the nut. When the lifting device is lifted, the bracket is supported below the vehicle body, and the screw rod is driven to rotate around the axis of the screw rod, so that the nut can drive the bracket to move upwards, and the lifting of the vehicle body is realized. Because the lifted vehicle weight is larger, the load born by the bracket and the nut is also larger, and the vehicle lifting machine is in unilateral unbalanced load operation, so that the nut bears larger unbalanced load torque, the axis of the nut is further deflected relative to the axis of the screw rod, the transmission is unsmooth, and the nut friction and wear phenomenon is serious. In the prior art, in order to make the nut transmission smoother and unobstructed, a common practice is to open an oil filling port on the nut and use an oil pump to fill grease into the oil filling port so as to improve the lubrication condition of the nut transmission. However, after the nut is loaded, the thread tooth type engagement surface is difficult to inject grease, grease is difficult to reserve, the deflection amount of the nut and the screw rod is large, the uniformity of oil injection is also influenced, good lubrication between the nut and the screw rod is not obtained, in addition, a large amount of injected grease can be extruded by the nut to cause waste, and the environment in a trolley machine and a maintenance workshop is extremely polluted.
