Abstract
The utility model provides a bearing measurer for a bridge model structure. The bearing measurer comprises a lever, weights and a bracket, and is characterized in that one end of the lever is rotatably fixed on the bracket, and the other end of the lever is detachably connected with the weights; a press rod is arranged on the lever in a position away from the fixed end by a distance of 1/11 of the length of the lever; and the bracket is fixed on a pedestal. By adopting the technical scheme, the bearing measurer has convenient operation, and can safely and reliably measure the bearing capacity of a bridge by adding the weights according to requirements. In addition, students can participate in the measurement, which is favorable for enhancement of the students' study interest and can quicken the game process.
Description
Technical field
The utility model relates to a kind of load-bearing measuring appliance, particularly a kind of bridge model structure bearing surveymeter.
Background technology
Bridge is a requisite buildings in the communications and transportation.The slip-stick artist goes to toward designing and producing bridge model earlier at the construction bridge, utilize the apparatus that can test the bridge bearing ability that bridge is tested then, and different types of rridges model structure load-bearing match also all needs to test the safe and reliable apparatus of bridge bearing ability.The method of existing test bridge bearing ability is to place a support at bridge floor middle part, and a groove is arranged on this support, is used for fixing to place several kilograms the counterweight of weighing, and this support is placed on the bridge usually temporarily, and it is not firm therefore easily to slide.Therefore this method is not easy to operate, and has certain danger, and the student can't participate in.We provide a kind of safe and reliable bridge model structure bearing surveymeter for this reason.
The utility model content
The utility model is exactly in order to address the above problem, and it is easy to operate and have the problem of certain risk to overcome the apparatus of existing test bridge bearing ability, and a kind of safe and reliable bridge model structure bearing surveymeter is provided.
The technical matters of the required solution of the utility model can be achieved through the following technical solutions:
A kind of bridge model structure bearing surveymeter, comprise lever, counterweight, support, it is characterized in that, described lever one end is rotatable to be fixed on the support, the other end can unload the connection counterweight, be provided with a depression bar with the stiff end distance for length 1/11st place of lever on the described lever, described support is fixed on the base.
The utility model adopts lever principle, and wherein power arm is the lever total length, and resistance arm is that lever turns stiff end to the distance between the depression bar, by the motive force of growth arm, shortens resistance arm, can obtain the resistance of several times in power.Therefore only need at the dynamic action point, promptly the lever other end hangs the counterweight of constant weight, just can obtain the resistance of several times in power, and the apparatus of existing test bridge bearing ability is more convenient during implementation and operation, and safe and reliable.
Concrete, the lever described in the present invention, counterweight, support all adopt the known technology in the prior art field, relevant lever, counterweight, support known solution in the prior art, and those skilled in the art all knows, so no longer repeat at this.
Owing to adopted technique scheme, the utility model is easy and simple to handle, and people can increase counterweight as required, safe and reliable mensuration bridge bearing ability, and the student also can participate in measuring, and helps improving students'interest in learning, also can accelerate the match process.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
As shown in Figure 1, a kind of bridge model structure bearing surveymeter of the utility model, comprise lever 3, counterweight 7, support 2, described lever 3 one ends are rotatable to be fixed on the support 2, the other end can unload and connect counterweight 7, be provided with a depression bar 6 with the stiff end distance for length 1/11st place of lever 3 on the described lever 3, described support 2 is fixed on the base 1.
When measuring bridge model; bridge model to be measured is placed on the base 1; then depression bar 6 is supported on bridge model bridge floor middle part; these depression bar 6 strong points are the drag effect point; at this moment begin at lever 3 other ends, promptly hang counterweight 7 on the dynamic action point gradually, counterweight 7 belows are placed with the protection cushion; cave in until bridge, measure the bridge bearing ability.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
