Embodiment Construction
[0017] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown, a vehicle overweight test alarm system based on a load-limited bridge of the present invention can send out an acousto-optic alarm and collect vehicle information when the vehicle exceeds the stress range of the bridge, including a groove 1 set on the bridge deck. The upper part of the groove 1 is covered by the cover layer 2;
[0019] A wheel pressure testing device is arranged in the groove 1, and the wheel pressure testing device includes a pressure bearing cap 3 and a support platform 4, a spring 5 is arranged between the pressure bearing cap 3 and the support platform 4, and the pressure bearing cap 3 An upper contact 6 is provided on the side facing the support platform 4, and a lower contact 7 is provided on the side of the support platform 4 facing the pressure cap 3, and there is a gap b...

The invention discloses a load-limiting bridge-based vehicle overweight testing and alarming system. The upper part of a groove is covered with a cover layer; a wheel-pressure testing device is arranged in the groove and comprises a pressure-bearing cap and a bracket table; a spring is arranged between the pressure-bearing cap and the bracket table; an upper contact is arranged on the pressure-bearing cap; a lower contact is arranged on the bracket table; and an alarm device is arranged outside the wheel-pressure testing device. Compared with the prior art, the load-limiting bridge-based vehicle overweight testing and alarming system has the advantages that the vehicle overweight testing and alarming system is simple in structure, small in construction difficulty, low in manufacturing cost and significant in effect, adjustment can be carried out according to the bearing capacity of different types of bridges and the bridges are effectively protected.
Description
technical field [0001] The invention relates to a pressure alarm system, in particular to a vehicle overweight test alarm system based on a load-limited bridge, which belongs to the field of bridge safety. Background technique [0002] In order to avoid bridge collapse and prolong bridge life, many bridges are equipped with warning signs or dynamic and static vehicle weighing systems, but this is only determined based on the rated load of the vehicle and has nothing to do with the structural safety of the bridge itself. A small vehicle with a rated load and overload does not pose a safety threat to the safety of a bridge with a large bearing capacity, but a heavy truck that is not overloaded may cause the bridge to collapse when it is lucky to get on the bridge. The tragedy caused serious loss of life and property. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a vehicle overweight test and alarm system based o...
