Abstract

The utility model relates to a grinder for the inner wall of a pipe fitting, which is particularly suitable for grinding the inner wall of the ductile cast-iron pipe. A front wheel and a rear wheel are arranged below a vehicle frame; the rear wheel is driven by a speed reduction motor fixed on the vehicle frame; the upper part of the vehicle frame is hinged with a bracket through a middle frame; a grinding rod is fixedly arranged on the bracket; a grinding head motor is fixedly arranged on the grinding rod above the front wheel; a grinding shaft driven by the grinding head motor is fixedly arranged on the grinding rod by a bearing; a grinding head is fixedly arranged at the front end of the grinding shaft; and a counterweight is fixedly arranged at the rear end of the grinding rod. The grinder has the advantages of small counterweight required and low electricity consumption.

Description

The ductile iron pipe inner wall sander
Technical field
The utility model patent relates to a kind of pipe fitting inner wall sander, is particularly suitable for the ductile iron pipe inner wall polishing and handles.
Background technology
The ductile iron pipe processing of before spraying, will polishing is to increase spraying effect.Traditional sander motor and bistrique are on the cantilever of mill bar, and this not only will have big counterweight could keep balance, and the walking power of sander is also bigger, and power consumption is big.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of ductile iron pipe inner wall sander, and its required counterweight is little, and power consumption is little.
The technical scheme that its technical problem of the utility model patent solution is taked is: there is front and back wheel the below of vehicle frame; Rear wheel is driven by the reducing motor that is fixed on the vehicle frame, and the vehicle frame top is hinged through middle frame and carriage, fixing mill bar on the carriage; Fixing grinding head motor on the mill bar above the front vehicle wheel; On the mill bar, the front end of mill axle is bistrique fixedly, the rear end fixed weight of said mill bar through bearing fixing for the mill axle that grinding head motor drives.
The left end of described vehicle frame and carriage is hinged through adjustment screw rod and spring, and the right-hand member of vehicle frame and carriage is hinged through pull bar.
The required counterweight of the utility model is little, and power consumption is little.Control flexibly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Accompanying drawing is the utility model structural representation.
The specific embodiment
Shown in accompanying drawing, there is front and back wheel 12,8 below of vehicle frame 9, and rear wheel 8 is driven by the reducing motor 7 that is fixed on the vehicle frame 9; Vehicle frame 9 tops are hinged with carriage 5 through middle frame 11; Vehicle frame 9 is hinged with spring 14 through adjustment screw rod 13 with the left end of carriage 5, and vehicle frame 9 is hinged through pull bar 10 with the right-hand member of carriage 5, fixing mill bar 3 on the carriage 5; Fixing grinding head motor 4 on the mill bar 3 above the front vehicle wheel 12; On mill bar 3, the front end of mill axle 2 is bistrique 1 fixedly, the rear end fixed weight 6 of said mill bar 3 through bearing fixing for the mill axle 2 that grinding head motor 4 drives.
