Abstract
The utility model discloses a vehicle for testing bridge model bearing capability. The utility model is characterized in that the utility model is composed of a vehicle pushing handle, mounting wheels, wheel shafts of loading barbells and shaft sleeves, wherein the vehicle pushing handle is formed by connecting a grasp handle and a force transmission handle through a shaft pin; the front end of the force transmission handle is sheathed with the wheel shafts; the wheel sleeves are sheathed with the wheel shafts at both sides of the force transmission handle; wheels are arranged on the wheel sleeves. Both sides of each wheel are respectively provided with a limiting sleeve which can move from left to right, and a loading sleeve which is capable of placing loading objects is arranged at one side of each limiting sleeve. One side of each loading sleeve is provided with a safety insurance ring, and the outer side of each safety insurance ring is provided with a safety sleeve. The utility model has the advantages of changeable wheel size, safe object load and convenient regulation. In addition, since the vehicle pushing handle is formed by connecting the two parts through the movable pin shaft, cheating can be prevented. Consequently, the vehicle is operated easily and safely; the vehicle is capable of simulating vehicle travel and testing the stress state and the loading capability of a model under the condition of relative motion, and the purpose of accurately testing the loading capability of models in researches, trainings and competitions is achieved.
Description
Technical field
The utility model relates to a kind of dolly that is used for bridge model and the test of other large span model load-bearing capacitys.
Background technology
When having the load-carrying members model measurement now, be directly disc to be deposited in the model top, carry out static test, the problem of existence has: 1, the disc heap is high more, and danger coefficient is big more.2, the student operating difficulties little to what strength.3, can not walk stressing conditions and the load-bearing capacity of test model under the relative motion situation by simulating vehicle.
Summary of the invention
The purpose of this utility model provides a kind of can the driving by simulating vehicle, and test dolly that ensure safety really, the accurate response load-bearing capacity can roll on bridge model.
The technical solution of the utility model is: a kind of bridge model load-bearing capacity test dolly, be characterized in, it is made up of the wheel shaft and the axle sleeve of trammer handle, installation wheel and load-carrying barbell, trammer handle is formed by connecting by pivot pin by handgrip handle and power transfer handle, power transfer handle front end sleeve is on wheel shaft, on the wheel shaft of power transfer handle both sides, be equipped with the wheel cover, wheel puts and is equipped with wheel, stop collar movably about the wheel both sides are equipped with, one side of stop collar has the load-carrying cover that can put loads, a side is overlapped in load-carrying the security insurance circle, and the security insurance circle outside is equipped with condom.
Because the stop collar of wheel both sides is removable, car opinion adjustable size is changed, and the load-carrying cover is spacing by security insurance circle and condom, and carrying weight safety is easy to adjust.Because trammer handle is to be formed by connecting by active pin shaft by handgrip handle and power transfer handle, force the operator directly to push away to stretch handle could promote dolly, prevent to practise fraud.Therefore, this dolly processing ease, safety, can simulating vehicle walking, stressing conditions and the load-bearing capacity of test model under the relative motion situation reaches the purpose of accurate metering model bearing capacity in scientific research, training, match.
