Abstract

The invention provides a tension machine tail vehicle test device. The device comprises a supporting device which is used for supporting the two ends of the bearing shaft in a tension machine tail vehicle; a loading device which is detachably connected with the bearing shaft and used for applying pressure to the bearing shaft; and a pressure test device which is arranged on the loading device and used for detecting the pressure borne by the bearing shaft. The pressure is applied to the bearing shaft through the loading device, the deformation situation of the bearing shaft is detected when the allowable load of the bearing shaft is reached, and then whether the strength of the bearing shaft meets the requirements is judged according to the deformation situation of the bearing shaft so that accurate selection of the bearing shaft can be ensured, the selected bearing shaft is enabled to meet the performance requirements of the tension machine tail vehicle, the safety coefficient is high, the model section accuracy of the bearing shaft can be enhanced, the situation that the selected bearing shaft has excessive strength can be avoided and weight and cost of the tension machine tail vehicle can be reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission line construction tools, in particular to a test device for a tension locomotive. Background technique [0002] With the rapid development of my country's economy and the rapid growth of electricity load, the erection of transmission line projects has also increased. Tension stringing construction is an important link in transmission line engineering, and the tension tail car for overhead transmission lines is one of the main equipment necessary for tension stringing construction. Construction is closely related, so ensuring the carrying capacity of the tension machine tail car is the basis for the smooth progress of tension pay-off. [0003] In order to ensure a stable supply of electric power, the requirements for construction equipment for tension stringing are gradually increasing. Among them, the bearing shaft of the tensioner tail car is an important construction part of the ten...
