Abstract
The utility model relates to a device for detecting a bumping post of a limited-width door during the driver examination. The device comprises a portal frame of the limited-width door and hanging rods on both sides in the portal frame of the limited-width door, wherein the hanging rods comprises two sections made of different materials, i.e., a metal rod is arranged at the upper part, and a plastic rod is arranged at the lower part; and a displacement detection device is arranged at the bottom of the plastic rod, and a return device is installed on the ground corresponding to the displacement detection device. The device for detecting the bumping post for the limited-width door during the driver examination can prevent the test vehicle from being scraped and can objectively reflect the post scraping situation of the test vehicle.
Description
Technical field
The utility model relates to driving test limit for width door.
Background technology
At present, driver's limit for width gantry crane bar that uses of taking an examination is an iron and steel material quality, and heavier, it is fixed on the portal frame of limit for width door by spring handle.Very easily spoil examining car when examining car and hitting on bar, during through grazing repeatedly, also camber of spring can occur, suspension rod is situation such as return in time.And can not objectively react examination car pole situation.
The utility model content
The utility model is at the deficiencies in the prior art, designed and developed out a kind ofly can not spoil examining car, and the driver that can the objectively respond examination car pole situation limit for width door lance pick-up unit of taking an examination.
The utility model is achieved through the following technical solutions:
Driver's limit for width door lance pick-up unit of taking an examination comprises limit for width door portal frame and is lifted on the suspension rod of both sides in the limit for width portal frame that described suspension rod is made up of two joints of unlike material, and top is Metallic rod, and the bottom is a plastic bar; The bottom of plastic bar is provided with displacement detector, and on the ground of displacement detector correspondence position returning device is installed.
Driver's limit for width door lance pick-up unit of taking an examination, described displacement detector is a magnetic inductor, described returning device is a magnet steel.
The utility model suspension rod is divided into two parts of unlike material, and top is Metallic rod, can guarantee that suspension rod is difficult for rocking, and the bottom is that plastic material can make and examines car and vehicle body can not spoilt when the bottom plastic bar is run in wiping.The bottom of plastic bar is provided with displacement detector, and on the ground of displacement detector correspondence position returning device is installed, and can make suspension rod be subjected to examining car like this and wipe when bumping displacement, can accurately objectively be detected.
Description of drawings
Accompanying drawing is a structural representation.
Embodiment
Shown in accompanying drawing.
Both sides are lifted with suspension rod in the utility model limit for width door portal frame 1, and suspension rod is made up of two joints of unlike material, and top is Metallic rod 2, and the bottom is a plastic bar 3; The bottom of plastic bar 3 is provided with magnetic inductor 4, and on the ground of magnetic inductor 4 correspondence positions magnet steel 5 is installed.The utility model suspension rod is divided into two parts of unlike material, and top is Metallic rod 2, can guarantee that suspension rod is difficult for rocking, and the bottom is that plastic bar 3 can make and examines car and vehicle body can not spoilt when bottom plastic bar 3 is run in wiping.The bottom of plastic bar 3 is provided with magnetic inductor 4, and on the ground of magnetic inductor 4 correspondence positions returning device magnet steel 5 is installed, and can make suspension rod be subjected to examining car like this and wipe when bumping displacement, can accurately objectively be detected.
