Abstract
The utility model relates to an overload protective device for a spring flexible shaft, which is used for pipeline cleaning equipment. The overload protective device for a spring flexible shaft is composed of an output shaft 1, an outer sleeve 3, a slider 5, a pressure spring 6, a sleeve 7, a positioning sleeve 8, etc. The output shaft 1 is provided with the outer sleeve 3. The sleeve 7 is arranged outside the positioning sleeve 8. The pressure spring 6 is arranged on the output shaft 1. The sleeve 7 is arranged at one end of the pressure spring 6. A pin 9 is arranged at the other end of the pressure spring 6. The slider 5 is arranged at the end part of the output shaft 1. The pin 9 is arranged on the slider 5. The outer sleeve 3 is provided with a pin shaft 4. The utility model can effectively protect the spring flexible shaft, an adjusting rod and a flexible shaft in the pipeline cleaning equipment.
Description
The utility model relates to the overload protection arrangement of spring flexible axle used in the line clear equipment.
At present, be used for the equipment of line clear, in the especially large-scale pipeline,, even damage because tamper more complicated, hard makes spring flexible axle, pole, flexible axle torsional deformation in the cleaning equipment easily, and to the not effectively protection of these parts.
The purpose of this utility model is to provide the overload protection arrangement of the spring flexible axle in a kind of line clear equipment.
The utility model is achieved in that by output shaft 1, screw 2, overcoat 3, bearing pin 4, slide block 5, stage clip 6, cover 7, positioning sleeve 8, pin 9 to be formed, overcoat 3 is arranged on the output shaft 1, cover 7 is arranged outside the positioning sleeve 8, and be connected with overcoat 3 by screw 2, being equipped with stage clip 6 on the output shaft 1, stage clip 6 one ends are to overlap 7, the other end is a pin 9, there is slide block 5 output shaft 1 end, is equipped with pin 9 on the slide block 5, and bearing pin 4 is arranged on the overcoat 3.
Fluted on the slide block 5.
Advantage of the present utility model is: owing to adopted parts such as slide block 5, stage clip 6; can effectively protect spring flexible axle, pole, flexible axle in the cleaning channels equipment; when in using, surpassing the bearing capacity of parts such as spring flexible axle, pole, flexible axle; cause the idle running that separates of overcoat 3 and output shaft 1; so, reach the purpose of parts such as protection spring flexible axle, pole, flexible axle.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of slide block 5.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is achieved in that by output shaft 1, screw 2, overcoat 3, bearing pin 4, slide block 5, stage clip 6, cover 7, positioning sleeve 8, pin 9 to be formed, overcoat 3 is arranged on the output shaft 1, cover 7 is arranged outside the positioning sleeve 8, and be connected with overcoat 3 by screw 2, being equipped with stage clip 6 on the output shaft 1, stage clip 6 one ends are to overlap 7, the other end is a pin 9, there is slide block 5 output shaft 1 end, is equipped with pin 9 on the slide block 5, and bearing pin 4 is arranged on the overcoat 3.
Fluted on the slide block 5.
Pack on the output shaft 1 and put stage clip 6 behind cover 7 and the positioning sleeve 8, refill top shoe 5, dress pin 9 is fixing on slide block 5, loads onto overcoat 3 subsequently, and is fastening with screw 2, and this moment, overcoat 3 should rotate freely, bearing pin 4 is loaded onto, and fastening nut.
In the use; the flange section of output shaft 1 is connected on the drive unit; when flexible axle that connects when overcoat 3 front ends or pole run into certain resistance; groove on the sliding sleeve 5 exceeds the pressure of stage clip 6; skid off bearing pin 4; thereby cause the idle running that separates of overcoat 3 and output shaft 1, reach the purpose of protection spring flexible axle, pole, flexible axle.
