The utility model relates to the technical field of connecting bolt between strand and short joint shaft in TSC exudator. It is a kind of expansion bolt pin, which comprises bolt rod and expansion sleeve. The middle part of the bolt rod is provided with a protrusion, the outer side of the expansion sleeve is cylindrical, the inner part of the expansion sleeve is provided with an installation through hole corresponding to the protrusion shape, and the lateral wall of the expansion sleeve is provided with an axial gap penetrating the left and right ends of the expansion sleeve. The expansion sleeve is arranged on the protrusion of the bolt rod, and the bolts on the left and right sides of the expansion sleeve are threaded with locking nuts capable of extruding the end faces of both sides of the expansion sleeve. The structure of the utility model is reasonable and compact. By tightening the locking nut, the expansion sleeve can move gradually along the lower part of the right side of the protrusion to the higher part of the left side of the protrusion. In this process, the expansion sleeve deforms under the combined action of the axial notch and the protrusion and extends outwards, and finally forms interference fit in the connecting hole between the short shaft flange and the strand flange, thus realizing the short shaft and stirring. Firm connection of belt.

胀紧螺栓销
本技术涉及TSC渗出器中绞带与短节轴连接螺栓的
,是一种胀紧螺栓销。
技术介绍
渗出器诞生至今,多段绞带与短节轴就采用过盈配合的大直径螺栓销进行连接,为了保证多段绞带的同轴度,必须用过盈配合螺栓销加以紧固,这种沿用已久的连接螺栓销,在装配和拆卸过程中非常困难,特别是拆卸中,很多螺栓容易损坏,渗出器大修,必须拆卸掉连接搅带的240个螺栓销,才能将搅带全部吊出,拆卸240个螺栓销需要8个壮劳力,15天左右才能拆卸完,需要较多人力物力,即费工又费时,而且拆下的螺栓销基本都已报废,不能再使用,而更换新的螺栓销就增加了二次检修的成本。
技术实现思路
本技术提供了一种胀紧螺栓销,克服了上述现有技术之不足,其能有效解决TSC渗出器在进行大修时,拆卸用来连接多段绞带与短节轴的螺栓销,费时费力、效率低并且容易损坏螺栓销、增加检修成本的问题。本技术的技术方案是通过以下措施来实现的:一种胀紧螺栓销包括栓杆、胀紧套,栓杆的中部外侧一体连接有左高右低并且呈圆台状的凸起,胀紧套的外侧呈圆柱状,胀紧套的内部设置有与凸起形状相对应的锥形安装通孔,胀紧套的侧壁上设置有贯穿胀紧套左右端面的轴向缺口,胀紧套套设在栓杆的凸起上,胀紧套左右两侧的栓杆上螺纹连接有能挤压胀紧套左右两侧端面的锁紧螺母。下面是对上述技术技术方案的进一步优化或/和改进:上述凸起左、右两侧的栓杆上分别设置有左部螺纹段、右部螺纹段,锁紧螺母分别安装在左部螺纹段与右部螺纹段上,在左部螺纹段右侧末端与凸起左侧端面之间的栓杆上设置有左环槽,在右部螺纹段左侧末端与凸起右侧端面之间的栓杆上设置右环槽。上述栓杆左右端面的外侧 ...
