Description
Technical field
The utility model relates to steel pipe manufacture field, specifically the ramming head stopping means of shot-blast apparatus in a kind of steel pipe.
Background technology
The inside and outside wall of large-scale steel pipe, before anticorrosion with painting coating, first must carry out sandblasting Shot Blasting, to remove Surface Rust.In steel pipe, shot-blast apparatus comprises ramming head arm and is arranged on the ramming head of ramming head arm end, and during work, ramming head extend in steel pipe, ejects steel sand shot, and along with rotation and the anterior-posterior translation of steel pipe, the rusty scale of inwall is impacted.But, the ramming head arm of interior shot-blast apparatus is longer, ramming head quality is very heavy again, and in practical work process, ramming head arm cannot keep level, ramming head sinking directly can contact steel pipe inner wall, cause the weak effect of sandblasting ball blast, eliminate rust uneven, even affect the normal operation of ramming head, and when steel pipe rotation and anterior-posterior translation, considerably increase resistance.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming the existence of above-mentioned prior art; the ramming head stopping means of shot-blast apparatus in a kind of steel pipe is provided; ramming head can be protected; make it unsettled in steel duct; it is avoided directly to contact steel pipe inner wall; both ensure the effect that eliminates rust, reduce again resistance when steel pipe rotation and anterior-posterior translation.
For this reason, the technical solution adopted in the utility model is as follows: the ramming head stopping means of shot-blast apparatus in steel pipe, its technical characteristic is, it comprises one and is nested with and the cylinder that can around ramming head arm rotate outer at ramming head arm, bearing is provided with, uniform multiple first roller of circumference on the outer wall of cylinder between described cylinder and ramming head arm; The external diameter that multiple first roller is formed is greater than the external diameter of ramming head.
The external diameter (i.e. the external diameter of multiple first roller formation) of ramming head stopping means is greater than the external diameter of ramming head, when ramming head sinks because of deadweight, the inwall of ramming head stopping means and steel pipe offsets, and makes ramming head unsettled in steel duct, avoid it directly to contact steel pipe inner wall, ensure that rust cleaning effect; In ball blast process, when steel pipe anterior-posterior translation, the first roller does relative scroll forward and backward on the inwall of steel pipe, when steel pipe time rotational, cylinder rotates thereupon, drives the first roller, coordinate steel pipe rotation, reduce the frictional resistance between steel pipe and ramming head stopping means.
As improvement, ramming head stopping means also comprises external diameter extension element, described external diameter extension element comprises annular plate and multiple circumference and is distributed on the second roller on annular plate, the outer end evagination of the second roller is in the outside of annular plate, and the inner side of annular plate is provided with the uniform locating hole of multiple circumference; The outer wall of described cylinder is formed the expansion circle of a ring shape, the uniform multiple installing hole of circumference on this expansion circle; Above-mentioned locating hole is corresponding with installing hole, and locks with screw and nut.This setting, make ramming head stopping means can increase diameter by installing external diameter extension element, with the steel pipe of adaptive different size specification, make ramming head as far as possible in the center of steel pipe, rocking of producing is also less, without the need to integral replacing ramming head stopping means, use more flexibly, operate time saving and energy saving; And the structure of ramming head stopping means is simple, assembling, convenient disassembly.
As improvement, the outside of described annular plate is also provided with the uniform extending bore of multiple circumference, and described extending bore can coordinate with the locating hole in another group of above-mentioned external diameter extension element, and is locked by screw and nut.This setting, makes the external diameter excursion of ramming head stopping means larger, can coordinate the steel pipe of more different size specifications, use more flexible, and easy to assembly, quick.
As improvement, described annular plate is also offered multiple material-saving hole, described material-saving hole circumference is uniform.This setting, makes the quality of ramming head stopping means light, reduces the labour intensity of installation.
As improvement, the first described roller and the second roller are polyurethane wheel.This setting, makes the quality of the first roller and the second roller light and wear-resisting, long service life.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
The ramming head stopping means of shot-blast apparatus in steel pipe as shown in Figure 1, comprises one and is nested with and the cylinder 1 that can around ramming head arm 6 rotate outer at ramming head arm 6, be provided with bearing 11, uniform multiple first roller 2 of circumference on the outer wall of cylinder 1 between described cylinder 1 and ramming head arm 6; The external diameter that multiple first roller 2 is formed is greater than the external diameter of throwing 7.
The external diameter (i.e. the external diameter of multiple first roller 2 formation) of ramming head stopping means is greater than the external diameter of ramming head 7, and when ramming head 7 sinks because of deadweight, the inwall of ramming head stopping means and steel pipe 8 offsets, and makes ramming head 7 unsettled inner at steel pipe 8.In ball blast process, when steel pipe 8 anterior-posterior translation, the first roller 2 does relative scroll forward and backward on the inwall of steel pipe 8, and when steel pipe 8 time rotational, cylinder 1 rotates thereupon, drives the first roller 2, coordinates steel pipe 8 rotation.
As shown in Figure 2, Figure 3, Figure 4, ramming head stopping means also comprises external diameter extension element 3.Described external diameter extension element 3 comprises annular plate 31 and multiple circumference and is distributed on the second roller 32 on annular plate 31.The outer end evagination of the second roller 32 is in the outside of annular plate 31, and the inner side of annular plate 31 is provided with the uniform locating hole of multiple circumference 33.The outer wall of described cylinder 1 is formed the expansion circle 4 of a ring shape, the uniform multiple installing hole 41 of circumference on this expansion circle 4; Above-mentioned locating hole 33 is corresponding with installing hole 41, and locks with screw and nut.
As shown in Figure 5, the outside of described annular plate 31 is also provided with the uniform extending bore of multiple circumference 5, and described extending bore 5 can coordinate with the locating hole 33 in another group of above-mentioned external diameter extension element 3, and is locked by screw and nut.Ramming head stopping means can increase diameter by installing external diameter extension element 3, with the steel pipe of adaptive different size specification, makes ramming head 7 as far as possible in the center of steel pipe 8.
Described annular plate 31 also offers multiple material-saving hole 34, and described material-saving hole 34 circumference is uniform.
The first described roller 2 and the second roller 32 are polyurethane wheel.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
