Embodiment
Purport of the present utility model is overcome the deficiencies in the prior art, there is provided a kind of bearing device manhole structure, improves
Boom hoisting part is added, in the case where manhole bolt is opened, using the boom hoisting, manually can easily lift people
Port lid end socket, then Unscrew manhole, reach the purpose that personnel can enter device interior operation.With reference to embodiment with reference to attached
Figure is described in detail, so as to which the technical characteristics of the utility model and advantage are interpretated more in-depth.
Overall structure diagram of the present utility model is as shown in figure 1, a kind of bearing device manhole structure, including manhole pipe nipple
1, the top of manhole pipe nipple 1 sets end socket 11, and manhole pipe nipple 1 is similar to tubular, and for maintenance personal access manhole, end socket 11 is people
Port lid, in working condition, it is covered on manhole pipe nipple 1, the end socket 11 is butterfly end socket.The outside of manhole pipe nipple 1 and envelope
First 11 junction sets a shell ring ring flat-plate 4, and the outside of end socket 11 sets a cover flange 5, manhole pipe nipple with the junction of manhole pipe nipple 1
1 both sides respectively set a journal stirrup 2, and journal stirrup 2, shell ring ring flat-plate 4 and cover flange 5 are fixedly connected by connector；The utility model
The connector includes eyelet bolt 7 and collar nut 8, and the lower end of eyelet bolt 7 is connected with journal stirrup 2 by a bearing pin 3, and sells
One steady pin is set on axle 3.Journal stirrup 2, shell ring ring flat-plate 4 and cover flange 5 are fixed up by eyelet bolt 7, because manhole
The both sides of pipe nipple 1 respectively set a journal stirrup, so the both sides of shell ring ring flat-plate 4 and cover flange 5 are also all correspondingly arranged through hole, work
When, manhole pipe nipple 1, shell ring ring flat-plate 4, cover flange 5, end socket 11 are fixed.In order to reach more preferable fixed effect, this practicality is new
