Tension machine is the machinery used when erecting power transmission lines, and is used for providing tension force to tow rope or cable, prevents unwrapping wire too fast in the process of trailing cable and tow rope.Motor is provided with in tension machine, an engine hood is had outside motor, motor there is a suction tude, engine air inlet tube needs to enter inside by engine hood and completes air inlet, usual engine hood is made of metal, motor can shake in the course of the work, the inner diameter edge of suction tude and engine metal cover can produce friction, after using a period of time, engine air inlet tube can be scratched by the inner diameter edge of metal covering, cause suction tude to scrap can not use, if there is the normal operation that explosion also can affect motor in suction tude in operation tension machine working procedure, also certain danger is brought to operation, and increase maintenance cost.
Model utility content
The utility model technical issues that need to address are to provide a kind of motor that can extend engine charge tube lifetime.
For solving the problems of the technologies described above; technical solution adopted in the utility model is: a kind of tension machine; comprise motor, engine hood, connection suction tude on the engine; suction tude reaches outside engine hood by the air inlet mouth of pipe of engine hood; at the air inlet mouth of pipe place of engine hood, rubber protective ring is installed; described rubber protective ring comprises with the central through bore with suction tude major diameter fit; rubber protective ring inner edge is set to rounded corners, and rubber protective ring outer rim is provided with the annular groove equipped with the air inlet mouth of pipe clamping of engine hood.
Further improvement of the utility model is: the thickness of rubber protective ring is not less than 20mm, and the annular groove degree of depth is 10mm, and annular groove width is corresponding with the thickness of air inlet mouth of pipe place engine hood.
Further improvement of the utility model is: the circular arc that described rounded corners is is radius with the thickness of rubber protective ring, circular arc is symmetricly set on the thickness direction of rubber protective ring.
Further improvement of the utility model is: annular groove inside edge is provided with inside projection, and the air inlet mouth of pipe edge of engine hood is provided with the hole clipping corresponding with projection.
Further improvement of the utility model is: the circumferencial direction of protruding annularly groove is evenly set to 2 ~ 6.
Owing to have employed technique scheme, the technological progress acquired by the utility model is:
The utility model is by being fixedly installed a rubber protective ring for extending the working life of suction tude at the engine hood suction port place of tension machine; the thickness of rubber protective ring is not less than 20mm; the depth of groove of annular entity is 10mm, and the circular hole that width and the thickness corresponding annular groove inside edge of air inlet mouth of pipe place engine hood are provided with 2 ~ 6 inside projections and engine hood suction port inner diameter edge supports the use.When installing rubber protective ring; the internal diameter at engine hood suction port place is embedded in the groove outside rubber protective ring annular entity; the projection correspondence of the inward at both ends up and down that recess edge is arranged is buckled in the circular hole of engine hood suction port inner diameter edge; realize the utility model and stable connection of engine hood suction port place circular inner diameter, prevent rubber protective ring from coming off due to vibrations in engine behavior.The admission line of tension machine enters engine interior by the central through bore place of rubber protective ring; the friction that motor shakes engine hood and the suction tude caused at work can be reduced because annular entity inward flange of the present utility model is provided with chamfering; prevent suction tude from killing curved and rupturing; extend the service time of suction tude, protection tension machine can not cause production accident because of breaking of admission line in normal working.
