Description

Switch machine contact set dynamometer Technical Field The utility model relates to the technical field of railway signal equipment detection, in particular to a switch machine contact set dynamometer. Background The switch machine is a power unit for railway switch conversion, the switch is driven to move by an action rod fixedly connected with a motor in the switch machine, railway reversing is completed, along with the increasing density of a railway network and the increasing speed of railway running, the performance requirement on the switch machine is also higher and higher, the pulling-in and extending action of the action rod of the switch machine is completed by switching a contact group controlled by a control center, namely, the switch is completed by the steering of the motor, the contact group is one of the most main components in the electric switch machine, the two arc-shaped contact pieces and the movable contact column are matched for use, the elastic force of the contact pieces directly influences the close fitting effect of the contact pieces and the contact column, and once the elastic force is reduced, the contact is required to be replaced, otherwise, poor contact is possibly caused, and hidden danger is brought to railway running. However, in the practical application process, the main means of the current pressure test on the contact plates is a handheld pressure tester, when the pressure tester is used for testing, the pressure test head needs to be extruded between the contact surfaces of the contact plates and the contact columns by manpower, and the contact plates are properly pulled out, at the moment, the tester displays pressure data, the tested data is unstable according to people, only one contact plate is tested at a time, a group of six contact plates of the contact group needs to be tested for six times, and the time and the labor are wasted, so that the contact group of a large number of switches is not beneficial to be tested in a limited skylight point. Disclosure of utility model The utility model discloses a switch machine contact set dynamometer, and aims to solve the technical problems in the background technology. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The switch contact set dynamometer comprises a dynamometer body and a contact assembly, wherein a display screen and keys are fixedly arranged on one side of the dynamometer body, a first baffle plate, a second baffle plate, a first probe assembly, a second probe assembly and a third probe assembly are respectively and fixedly arranged on the other side of the dynamometer body. The first probe assembly consists of a first conducting sheet, a second conducting sheet, a first pressure diaphragm, a second pressure diaphragm and a supporting plate. The backup pad of setting for on first conducting strip and the second conducting strip are conducted to the pressure of first contact piece and second contact piece, the pressure on first pressure diaphragm and the second pressure diaphragm of conduction afterwards can not influence each other, can carry out a plurality of contact pieces simultaneously with this and test, labour saving and time saving, convenient test a large amount of switch contact sets, improved the availability factor of this dynamometer. The contact assembly comprises a first contact piece, a second contact piece, a third contact piece, a fourth contact piece, a fifth contact piece and a sixth contact piece which are fixedly arranged on one side of the contact assembly.
