Abstract
The utility model discloses a test device for simulating pressure of a wheel. The test device comprises a support and a jack, wherein an upper end of the support is provided with a support seat used for fixing a jack cylinder, a lower end of the support is provided with a base board, a push rod of the jack is arranged in the support, and a tail end of the push rod is sequentially provided with a pressure sensor, a guide mechanism and a clamping mechanism for the wheel. Through ingenious combination of the jack, the pressure sensor and the clamping mechanism for the wheel, when different pressures are exerted on the wheel by the jack, operation situations of the wheel under various conditions are reflected through the pressure sensor; the guide mechanism employs a guide board to match with a linear slide track, left and right axial swing of the push rod is avoided in a downward pressing process of the push rod of the jack, so the push rod is more stable; the guide board and the linear slide track are mutually matched, a friction coefficient is small, so downslide stability and reduction of downslide friction resistance are excellently guaranteed. The test device has advantages of compact structure, small volume, low manufacturing cost and simple and convenient operation.
Description
Technical field
The utility model relates to wheel wheel load power fields of measurement, relates 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 the various parameters of wheel and crane by calculating wheel load, simultaneously, before manufacture 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 scientific research to influence degree of the performance of locomotive etc.
Summary of the invention
The utility model purpose is to overcome the deficiency that above-mentioned prior art exists, and a kind of simple in structure, wheel load data proving installation that simulating wheel pressurizes accurately is provided.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The proving installation of a kind of simulating wheel pressurization, comprise support, lifting jack, in the upper end of support, is provided with 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 is placed in support, and the end of push rod is disposed with the clamping device of pressure transducer, guiding mechanism, wheel.
Guiding mechanism comprises guide plate and the line slide rail for guide plate is led, and 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.
On base plate, put, the inboard of support also is provided with lower reinforcement gusset.
Compared with prior art, the utility model at least has following advantage and effect:
The ingenious combination of the clamping device by lifting jack, pressure transducer and wheel, the jack pair wheel applies different pressure, by pressure transducer, reacts accurately the ruuning situation that wheel is got off in various working;
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 coordinate, and makes the push rod of lifting jack not there will be push rod Y-axis pendulum problem 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 glided and reduce the frictional resistance glided.
Upper reinforcement gusset and lower reinforcement gusset have further strengthened bearing capacity.
This proving installation is simple in structure, is well positioned to meet the testing requirements in laboratory, can provide effective simulation downforce for pressing down of wheel.
The utility model compact conformation, volume are little, cheap, easy to operation.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 side-looking structural representation.
Embodiment
Below in conjunction with specific embodiment, the utility model is more specifically described in detail.
Embodiment
As shown in the figure.The proving installation of a kind of simulating wheel of the utility model pressurization, comprise support 6, lifting jack 1, in the upper end of support 6, is provided with for the fixing supporting seat 4 of lifting jack 1 cylinder body, and the lower end of support 6 is provided with base plate 13; The push rod 2 of lifting jack 1 is placed in support 6, and the end of push rod 2 is disposed with the clamping device 10 of pressure transducer 7, guiding mechanism, wheel 11.Lifting jack 1 adopts electric hydraulic lifting jack, and its push rod 2 strokes at least reach 400mm.
Guiding mechanism comprises guide plate 8 and the line slide rail 5 for guide plate 8 is led, and this line slide rail 5 is arranged at the inboard of support 6.Guiding mechanism makes the push rod 2 of lifting jack 1 not there will be push rod 2 Y-axis pendulum problems in pressing down process, makes it more stable; Guide plate and line slide rail cooperatively interact, and its friction factor is very little, can well guarantee the stability glided and reduce the frictional resistance glided.
Clamping device 10 is connected with the push rod 2 of lifting jack 1 by flange 9.
Below supporting seat 4, the inboard of support 6 is welded with and strengthens gusset 3; On base plate 13, put, the inboard of support 6 also is provided with lower reinforcement gusset 12.
This device course of work is as follows: wheel 11 that will be to be tested is fixed on clamping device 10 in advance, startup along with lifting jack 1, wheel 11 is along with push rod 2 moves downwards, after wheel 11 is subject to the backstop of base plate 13, the thrust of push rod 2 is on wheel 11, pressure transducer 7 is subject to the extruding of push rod 2, thereby accurately measures pressure, and this pressure be the wheel load power of wheel 11.
The descending stroke of push rod 2 is larger, larger to the extruding dynamics of wheel 11.
Embodiment of the present utility model is not restricted to the described embodiments; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
