Abstract

The invention discloses a testing device for simulating wheel pressurization. The testing device for simulating the wheel pressurization comprises a support and a jack, wherein a supporting seat which is used for fixing a cylinder body of the jack is arranged at the upper end of the support, a base plate is arranged at the lower end of the support, a push rod of the jack is arranged inside the support, and a pressure sensor, a guiding mechanism and a clamping mechanism of wheels are sequentially arranged at the tail end of the push rod. Through ingenious combination of the jack, the pressure sensor and the clamping mechanism of the wheels, pressure with different amplitudes is exerted on the wheels by the jack, and running conditions of a vehicle are reflected accurately through the pressure sensor when the wheels are in different working conditions. The guiding mechanism is matched with a straight slide rail through a guide plate, left-right swing of the push rod of the jack does not occur in the pressing-down process so that the push rod can be more stable. The guide plate is matched with the straight slide rail, the friction coefficient between the guide plate and the straight slide rail is very small, therefore, the sliding-down stability can be well ensured, and the sliding-down friction resistance is reduced. The testing device for simulating the wheel pressurization is compact in structure, small in size, low in manufacturing cost and convenient and easy to operate.

Description

A kind of proving installation of simulating wheel pressurization
Technical field
The present invention relates to wheel wheel load power fields of measurement, relate in particular to a kind of proving installation of simulating wheel pressurization.
Background technology
The locomotives such as crane are in operational process, wheel load is a very important factor, in the time of general design crane, need to design by calculating wheel load the various parameters of wheel and crane, simultaneously, before manufacturing practice locomotive, all need to do the test about wheel load, determine the reasonable value of this wheel wheel load, simultaneously, also need to study wheel load in the scientific research research to influence degree of the performance of locomotive etc.
Summary of the invention
The object of the invention is to overcome the deficiency that above-mentioned prior art exists, and a kind of proving installation of simple in structure, accurately simulating wheel pressurization of wheel load data is provided.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The proving installation of a kind of simulating wheel pressurization comprises support, lifting jack, is provided with in the upper end of support for the fixing supporting seat of lifting jack cylinder body, and the lower end of support is provided with base plate; The push rod of lifting jack places in the support, and the end of push rod is disposed with the clamping device of pressure transducer, guiding mechanism, wheel.
The line slide rail that guiding mechanism comprises guide plate and is used for guide plate is led, this line slide rail is arranged at the inboard of support.
Clamping device is connected with the push rod of lifting jack by flange.
Below supporting seat, the inboard of support is welded with and strengthens gusset.
Put on the base plate, the inboard of support also is provided with lower reinforcement gusset.
Compared with prior art, the present invention has following advantage and effect at least:
The ingenious combination of the clamping device by lifting jack, pressure transducer and wheel, the jack pair wheel applies different pressure, reacts accurately the ruuning situation that wheel is got off in various working by pressure transducer;
Adopt lifting jack as press member, it is slow that it presses down process, guaranteed the down force pressure value stabilization.
Guiding mechanism adopts guide plate and line slide rail to cooperate, and makes the push rod of lifting jack push rod Y-axis pendulum problem can not occur in pressing down process, makes it more stable; Guide plate and line slide rail cooperatively interact, and its friction factor is very little, therefore, can well guarantee the stability that glides and reduce the frictional resistance that glides.
