Problems solved by technology
The distance between the contact position of the contact wire and the pantograph and the center line of the pantograph is called the pull-out value. Only when the contact position of the contact wire and the pantograph meets the requirements of the pull-out value allowed by the design can the wrist arm be put into use normally , otherwise the contact line may not be in contact with the pantograph. In order to avoid this situation being discovered after the wrist arm is installed, it is necessary to conduct a simulation test before the wrist arm is put into use. Correction, there is still a lack of devices in the prior art that can simply and quickly perform simulation tests on the wrist arm

According to a cantilever simulation test device, a simplified cantilever comprises a positioner, the device comprises a pantograph, a posture adjusting mechanism used for adjusting the posture of thepantograph and a pointer connected with the pantograph in a sliding mode, and the pointer is detachably connected with the positioner. The invention provides a cantilever simulation test device, which can simply and quickly carry out a simulation test on a pull-out value of a simplified cantilever.
Description
technical field [0001] The invention relates to the technical field of wrist arm production, in particular to a wrist arm simulation test device. Background technique [0002] In the traction power supply system, the wrist arm is an important part of the catenary. The wrist arm is usually installed on the upper part of the pillar to support the contact suspension and play the role of load transmission. The wrist arm is generally made of circular steel pipes with a length of It is related to factors such as the structural height of the contact suspension, the side boundary of the pillar, and the location of the pillar. When the wrist arm is in use, the locator is used to connect the contact wire. The contact wire is in contact with the pantograph on the locomotive to provide power to the locomotive. When the locomotive is running at high speed, the pantograph will rub against the contact wire violently , causing the pantograph to wear out quickly. In order to avoid the break...
