Abstract
The utility model provides a device used for preventing connection bolts of an electric roller outer end cap and an inner speed reducer end cap from falling off, and belongs to the technical field of belt electric rollers. The device used for preventing the connection bolts of the electric roller outer end cap and the inner speed reducer end cap from falling off mainly resolves the problems that after the belt electric roller operates for a period of time under a well, due to the fact that the connection bolts of the vibration belt electric roller outer end cap and the inner speed reducer end cap loosen and slide, a spring cushion becomes ineffective, the bolts can even fall into the roller and damage gears of the electric roller and the speed reducer, a motor is burned out, the working surface is stopped for overhaul, and time and labor are consumed when the electric roller is replaced. The device used for preventing the connection bolts of the electric roller outer end cap and the inner speed reducer end cap from falling off comprises the bolts and a metal wire, and is characterized in that a bolt cap of each bolt is provided with a transverse through hole, at least two adjacent bolts form a falling-prevention set, the metal wire sequentially penetrates the through hole in each bolt cap, and the two ends of the metal wire are twisted together to form a closed-loop falling-prevention system. The device can be applied to equipment with parts connected through bolts in a vibration environment.
Description
Technical field
The utility model belongs to belt electric drum technical field, is specifically related to electric drum outer end cap and interior retarder end cap connecting bolt anti-drop device.
Background technique
The belt electric drum, what outer end cap was connected employing usually with interior retarder end cap is the mode that bolt and spring washer compresses, because during the running of belt electric drum, be in vibrating state, when the belt electric drum after down-hole operation a period of time, becoming flexible can appear in the connecting bolt on belt electric drum outer end cap and the interior retarder end cap, slide fastener, stripped thread, the inoperative phenomenon of spring pad, even bolt is fallen in the cylinder, cause the electric drum reducer gear to damage, motor burns out, and causing the working surface stop production to overhaul and changing electric drum wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and electric drum outer end cap and interior retarder end cap connecting bolt anti-drop device are provided.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be:
Electric drum outer end cap and interior retarder end cap connecting bolt anti-drop device comprise the bolt and the wire that are fixed on the end cap, are characterized in that the nuts of described bolt arranges cross through hole, and at least two adjacent bolts are formed the Drop-proof group; Described wire passes the through hole on each nuts in the Drop-proof group successively, and two wire termination wringings form closed loop Drop-proof system together; Perhaps the wire termination forms open loop Drop-proof system around its nuts half-turn that passes and self wringing together.
Described wire adopts iron wire.
Described wire adopts steel wire.
The beneficial effects of the utility model are because employing is through the grouping of end cap connecting bolt together with it by wire, reach the purpose of Drop-proof, have effectively avoided the generation of accident, make to produce to have obtained safety guarantee.

Among the figure: 1-nuts; 2-wire; 3-end cap; 4-through hole.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, electric drum outer end cap and interior retarder end cap connecting bolt anti-drop device, comprise the bolt and the wire 2 that are fixed on the end cap 3, as Fig. 4, Fig. 5 and shown in Figure 6, the nuts 1 that is characterized in described bolt arranges cross through hole 4, and at least two adjacent bolts are formed the Drop-proof group; Described wire 2 passes in the Drop-proof group 4, the two wire termination wringings of the through hole on each nuts together successively, as depicted in figs. 1 and 2, forms closed loop Drop-proof system; Perhaps the wire termination as shown in Figure 3, forms open loop Drop-proof system around its nuts half-turn that passes and self wringing together.
Described wire adopts iron wire.
Described wire adopts steel wire.
Using method and working principle
When the utility model uses, the bolt on the end cap 3 is tightened, again wire is passed the through hole 4 on the adjacent nuts 1, at least two one group, the wire termination around the nuts half-turn that passes and self wringing together, perhaps two wire terminations link together, and form the Drop-proof system.If in a certain anticreep system bolt looseness is arranged, owing to have wire to pass on the nuts, can't change whole circle, therefore, even bolt is loosening, can not come off yet.
Claims (4)
