Embodiment 1

[0058] Such as Figure 1-3 As shown, a novel steel pipe internal protrusion grinding device includes a protrusion grinding assembly 1, and the protrusion grinding assembly 1 includes a grinding part 11, and the grinding part 11 includes 3 fan-shaped grinding rods 111 distributed in an annular array (according to the existing Grinding tool design, the surface of the fan-shaped grinding rod 111 has a rough rubbing structure, such as a grinding raised structure, which is convenient for grinding and smoothing the protrusions on the inner wall of the pipeline), and the length of the fan-shaped grinding rod 111 is 2.5m, so it can be applied to the length of the pipeline Sanding for large pipes up to 2.5m.

[0059] The left and right ends of the three fan-shaped grinding rods 111 are fixedly connected with mounting discs 112 , and shafts 114 are fixedly connected between the mounting discs 112 . Specifically, the left side wall and the right side wall corresponding to the fan-shaped...

Embodiment 2

[0078] Such as Figure 1-4 As shown, this embodiment is based on the structure disclosed in Embodiment 1, in order to realize that the left end frame 3 can be flexibly separated from the shaft 114 (to facilitate pushing the steel pipe to the fan-shaped grinding rod 111) and flexibly install the shaft 114 to the left end On the frame 3, it is convenient for the shaft rod 114 to be rotationally connected with the left end frame 3. Adopt the following structural design:

[0079] The left end of the shaft 114 is fixedly connected with a hexagonal clip 1141 (the left end of the shaft 114 passes through the mounting plate 112 on the left side and is connected to the mounting plate 112 in this position); the left end frame 3 is fixed A special-shaped bearing 32 matched with the hexagonal clip 1141 is connected. Wherein, the main structure of the special-shaped bearing 32 is the same as that of the existing rolling bearing, the difference is that the inner ring 322 of the special-sh...

Embodiment 3

[0089] Such as Figure 1-9 As shown, on the basis of Example 2, this embodiment adopts the following structural design in order to realize the technical defect that the steel pipe rolls due to friction during the grinding process:

[0090] The novel steel pipe internal protrusion grinding device also includes a locking device 4, and the locking device 4 is located directly above the fan-shaped grinding rod 111 . Cooperating with the corrugated support plate 22 by the locking device 4 prevents the steel pipe from rolling.

[0091] The concrete structure of locking device 4 is as follows:

[0092] The locking device 4 includes several arc-shaped rods 41 distributed at intervals on the left and right, and the bottoms of the several arc-shaped rods 41 are distributed with several extruded locking parts 44 in an arc-shaped distribution; the several arc-shaped rods 41 The front and rear ends of the front and rear ends are fixedly connected with end side plates 411 .

Abstract

The invention discloses a novel grinding device for inner protrusion of a steel pipeline. The device comprises a protrusion grinding assembly, the protrusion grinding assembly comprises a plurality offan-shaped grinding rods distributed annularly, the left ends and the right ends of the multiple fan-shaped grinding rods are fixedly connected to mounting disc bodies, a shaft rod is fixedly arranged between the mounting disc bodies in a connection mode, the left end of the shaft rod penetrates through the mounting disc bodies, and the left end of the shaft rod is rotationally connected to a left end frame; the left end frame is detachably mounted on the shaft rod; the protrusion grinding assembly further comprises a driving motor; the driving motor is fixedly connected to a right end frame;the device further comprises a supporting assembly, and the supporting assembly is located under the fan-shaped grinding rod; and the supporting assembly comprises a corrugated supporting plate, thecorrugated supporting plate is provided with an arc-shaped recess, and supporting frames are fixedly connected to the front end and the rear end of the corrugated supporting plate. By means of the parts of the device, the inner side walls of steel pipes of different specifications and sizes are automatically ground, and the technical defects that the grinding efficiency is low and operation is unsafe when workers enter large steel pipes are overcome.

Description

technical field [0001] The invention relates to the field of steel pipeline grinding devices, in particular to a novel steel pipeline internal protrusion grinding device. Background technique [0002] Steel pipes, especially large steel pipes, are pipeline components that are often used in industrial production. In the production process of steel pipes, not only the outer wall of the steel pipe needs to be polished and polished, but also the inner wall of the pipe needs to be polished. The protrusions inside the pipe are ground to a smooth finish. [0003] Because the inner wall of a large pipeline not only has a large space range but also has a deep length, machine grinding remains unchanged. Most of the prior art uses manual entry into the pipeline, and a hand-held small grinding machine grinds each position of the inner wall of the pipeline. [0004] This type of grinding is not only inefficient, but also because manual access to the inside of the pipeline is used for gr...
