Description
Technical Field
The utility model belongs to the technical field of mechanical tool design, particularly belongs to the technical field of railway equipment installation tool design, and relates to a railway wagon axle temperature monitoring sensor installation tool.
Background
The axle temperature detection device of the railway freight train mainly uses a non-contact infrared axle temperature detection system, and the axle temperature is detected by installing infrared probes every 30 km. Due to the special environment of train operation, the existing infrared axle temperature detection system is easily influenced by external environment and is difficult to position, so that the alarm rate of over-high axle temperature is low, the false alarm rate is high, and the operation and maintenance cost is high.
In order to further reduce the running risk and maintenance cost of railway vehicles and promote the intelligent development of railway freight cars, the conventional axle temperature detection system needs to be capable of monitoring the change of the axle temperature at any time and monitoring the axle temperature effectively in time. The conventional shaft temperature monitoring method is that a temperature sensor is directly contacted with a bearing through a bearing saddle, so that the change of the bearing temperature of a vehicle in the running process is directly reflected to the temperature sensor and is transmitted to a terminal through a lead for monitoring by workers.
Cast steel three-piece bogie is basically assembled on railway freight trains in China, and because the bearing, the bearing saddle and the side frame guide frame are fixed in assembly structure, the operable space is limited, so that the conventional wrench cannot be used for applying torque force when the axle temperature monitoring sensor is installed, and meanwhile, the problem that the temperature sensor cannot be fastened due to too small manual torque force is seriously influenced by the installation of the axle temperature monitoring sensor during the operation of the railway freight trains. Therefore, it is necessary to design a special tool to improve the installation method of the axle temperature monitoring sensor of the railway wagon, so that the axle temperature monitoring sensor can be conveniently installed, and the installation efficiency of the sensor can be improved.
Disclosure of Invention
The utility model discloses a mounting tool for a wagon axle temperature monitoring sensor according to the defects of the prior art.
Railway freight car axle temperature monitoring sensor mounting tool, its characterized in that: the mounting tool is a hollow cylindrical sleeve, a central hole of the sleeve is matched with a hexagonal nut used for mounting the shaft temperature monitoring sensor and can be sleeved in a hexagonal inner hole for driving rotation, the outer diameter of the sleeve is smaller than the diameter of a counter sink hole of the bearing saddle used for mounting the shaft temperature monitoring sensor, the length of the counter sink hole is larger than the depth of the counter sink hole, and a handle jack arranged in the radial direction is arranged on the wall of one end of the sleeve.
The handle insertion holes are arranged on the sleeve wall in a plurality.
The sleeve wall is axially provided with a slot running through the sleeve in the axial direction.
The tool is a special sleeve with a radial handle jack, an inner ring of the special sleeve is an open hexagon matched with a temperature sensor mounting hexagon nut, and a certain small gap is reserved between the inner ring of the special sleeve and the temperature sensor mounting hexagon nut, so that the temperature sensor can be conveniently placed in and taken out, and the special sleeve can be ensured to clamp the temperature sensor mounting hexagon nut to apply torsion.
The shaft temperature monitoring sensor is installed by adopting the tool, and a threaded hole and a sinking platform hole which are coaxial are preset on the bearing saddle.
When the mounting tool is mounted, the temperature sensor is sleeved into the special sleeve, so that the torque for screwing the temperature sensor into the bearing saddle is increased, and the problems that the conventional wrench cannot be used for applying the torque, the manual torque is too small, or the temperature sensor cannot be fastened when the shaft temperature monitoring sensor is mounted are solved. The whole installation process is simple and quick, the working efficiency is improved, and the working time is saved.
