In order to achieve the purpose, the utility model is realized by the following technical scheme:

the utility model provides a safety device of bridge inspect vehicle, includes the work arm body, parallel arrangement has an at least crashproof board on the side of work arm body, crashproof board is equipped with the wave form board including mutual parallel arrangement's first base plate and second base plate, pressing from both sides between first base plate and the second base plate, crashproof board passes through shock attenuation pole and work arm body fixed connection.

In the utility model, the working arm body is conventional in the field, and can be a folding arm type working arm or a truss type working arm; when the impact prevention plate is provided on the truss-type working arm, since the horizontal truss of the truss-type working arm generally serves as a working platform for movement of the inspector, the impact prevention plate should be mainly provided on both sides of the horizontal truss perpendicular to the horizontal plane. In addition, the first substrate, the corrugated plate and the second substrate are connected in a conventional manner, for example, they may be bonded, or they may be fixedly connected by fasteners such as screws or bolts.

When the working arm collides with the bridge body, the anti-collision plate arranged on the outer side of the working arm body is firstly contacted with the bridge body, and the corrugated plate deforms and absorbs collision energy so as to reduce the impact of collision on the working arm body; the shock-absorbing rod can further weaken the intensity of the collision energy when the collision energy is transmitted to the working arm body from the anti-collision plate, so that the working arm body is prevented from being damaged or deformed, and the safety of bridge detection operation is ensured.

Furthermore, a rubber layer is further arranged on the side face, far away from the working arm body, of the anti-collision plate, and is used for reducing damage to the bridge body when the anti-collision plate collides with the bridge body.

Furthermore, a plurality of the anti-collision plates are uniformly distributed on the side surface of the working arm body at equal intervals. The plurality of the anti-collision plates are arranged in a split mode, so that the damaged anti-collision plates can be replaced in time.

Further, the shock attenuation pole includes the cylinder body and the body of rod, the one end of the body of rod stretches into the cylinder body with cylinder body sliding fit, and the terminal surface of the body of rod is equipped with damping spring with the damping intracavity that the cylinder body formed is coaxial, damping spring one end and cylinder body fixed connection, the other end and body of rod fixed connection. When the shock absorption rod is extruded in a direction parallel to the axial direction, the shock absorption spring is pressed to absorb energy and shorten the shock absorption rod, and the shock absorption rod can play a role in buffering impact force transmitted from the direction of the anti-collision plate, so that damage to the working arm caused by collision is reduced.

Further, the terminal surface that the body of rod was kept away from to the cylinder body is equipped with first mounting panel, the terminal surface that the body of rod was kept away from to the body of rod is equipped with the second mounting panel, first mounting panel and crashproof board fixed connection, second mounting panel and work arm body fixed connection.

Other components that enable proper use of the safety shield apparatus are also included in the present invention and are conventional in the art. In addition, the devices or components which are not limited in the present invention are all conventionally used in the art, for example, the working arm body, the first base plate, the second base plate, the corrugated plate, the rubber layer, the cylinder body, the rod body, the damping spring, the first mounting plate, the second mounting plate, and the like are all conventionally arranged.

The working principle of the utility model is as follows:

Compared with the prior art, the utility model has the beneficial effects that:

this device is through setting up crashproof board in the working arm body outside, can effectively alleviate the damage that the collision caused the working arm when working arm and pontic bump, reduces the cracked possibility of working arm to guarantee the security of bridge detection operation.
