Description
Technical Field
The utility model relates to a foundation ditch protection technical field, concretely relates to foundation ditch safety device.
Background
A foundation pit is a space below the ground excavated for constructing a foundation of a building (including a structure). Because a fall exists between the foundation pit and the road surface, a safety protection device needs to be arranged around the foundation pit in the foundation pit construction process.
General foundation ditch safety device adopts the steel pipe component and uses the close mesh formula safety net to seal, can warn current personnel and vehicle effectively through this kind of mode, but when accident takes place, for example the car is out of control or leads to the vehicle to rush to the foundation ditch in the construction because the driver is neglected, this kind of protector often can not play real guard action. For most protective devices with general stability, larger impact force can damage the protective devices, so that the automobile can easily break the protection and fall into a foundation pit to cause major safety accidents; for some protective devices with high stability, the automobile can be effectively prevented from falling into a foundation pit, but at the moment, the automobile can cause injury which is difficult to estimate to people in the automobile when the automobile collides.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a foundation ditch safety device aims at improving safety protection performance through weakening the impact force.
The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme: the utility model provides a foundation ditch safety device, includes the fixed plate, is used for weakening the buffer board of impact force and sets up the compression spring between buffer board and fixed plate, the fixed plate is fixed in ground, the side of buffer board with the side that the foundation ditch was kept away from to the fixed plate rotates and connects, compression spring one end fixed connection in buffer board and other end fixed connection in the fixed plate.
Through adopting above-mentioned technical scheme, receive horizontal impact when the buffer board, for example during the clashing of car, the buffer board receives the power of clashing to pass to compression spring buffer board and take place to rotate simultaneously, the impact force is decomposed into the power of two directions along buffer board surface and perpendicular buffer board by the buffer board when contacting the buffer board, the power of perpendicular buffer board direction is turned into compression spring's elastic potential energy, thereby weaken very big partial impact force, the car still need overcome self gravity if continuing the antecedent along the buffer board this moment, it hardly continues to pass through the buffer board and gets into the foundation ditch. By adopting the above mode, not only can reduce the possibility that the automobile falls into the foundation pit, but also reduce the impact force that the driver received when the automobile and the protector bump, the safety protection performance is more extensive.
The utility model discloses further set up to: the buffer board inclines, the relative buffer board bottom in buffer board top is closer to the foundation ditch.
Through adopting above-mentioned technical scheme, the buffer board bottom rotates with the fixed plate to be connected, and the relative buffer board bottom in buffer board top is towards the foundation ditch slope for the car is when striking the buffer board, and the buffer board can take place to rotate betterly and cooperate compression spring to realize its buffer function.

Because the buffer board has weakened the impact force and has gravity to act on the car, the impact force of actual car when the baffle bumps can greatly reduce the injury that car and interior personnel caused. Through this kind of mode, further reduced the car and fallen into the possibility of foundation ditch, and the injury to personnel in the car on the whole also has greatly reduced.
The utility model discloses further set up to: the baffle is perpendicular to the buffer plate.
Through adopting above-mentioned technical scheme, baffle perpendicular to buffer board for the baffle reaches the optimum to the effect that blocks of car, and the car is advancing along the buffer board surface and when bumping with the baffle, and the baffle produces the reaction force that offsets car impact force size the same to the car, and consequently it blocks the effect best.
