Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, fixed support 1 mainly includes metal rack, metallic plate and protection network etc., protection network includes upper end protection network 11 and lower end protection network 12, fixed support 1 is provided with upper end protection network 11 and lower end protection network 12, upper end protection network 11 and lower end protection network 12 by rotating shaft 28 cigarette at fixed support 1 upper and lower end at upper and lower end；Fixed support 1 is mainly used to fixing pass closed system 1, is fixed on ferrum floor 48 by whole preventer, it is ensured that preventer is stablized firm.Meanwhile, after impact block 44 clashes into preventer, play buffering and barrier effect preferably；
As shown in Figure 2, described pass closed system 2 includes the upper end wind spring 21 connecting and controlling upper end protection network 11 and rotating shaft 28 thereof, with the lower end wind spring 22 connecting and controlling lower end protection network 22 and rotating shaft 28 thereof, described upper end wind spring 21, lower end wind spring 22 are respectively equipped with relieving mechanism 23 with fixed support 1 junction；Described relieving mechanism 23 connects described control system 3, is used for discharging protection network；Being provided with motor 25 bottom described fixed support 1, described motor 25 connects described rotating shaft 28；Being additionally provided with photocell 24 on described fixed support 1, described photocell 24 connects described control system 3, is used for providing triggering signal；
Upper end wind spring 21 and lower end wind spring 22 before releasing, are in compressive state, for stored energy, it is ensured that protection network before releasing, has bigger interior energy.During release, upper end wind spring 21 promotes upper end protection network 11 sharp downward movement, lower end wind spring 22 promotes lower end protection network 12 fast upward motion, this makes it possible at a very rapid rate, before impact block 44 returns to protection network, close rapidly protection network, stop that impact block 44 continues to move to impact device 47.
Photocell 24 is used for providing flop signal.When not having object to pass through protection network, photocell 24 is in channel status " 1 "；When there being object to pass through protection network, photocell 24 is in off state " 0 ", at this moment sends one and triggers signal, is delivered to control system 3.Control system 3 processes (such as time delay etc.) through certain, and to relieving mechanism 23 signal, relieving mechanism 23 discharges protection network.Protection network is under the promotion of upper end wind spring 21 and lower end wind spring 22, rapidly to intermediary movements, closes protection network；
Motor 25 is for resetting upper end protection network 11 and lower end protection network 12.After protection network discharges, mediate state.Before using next time, it is necessary to upper end protection network 11 returns to upper end initial position, and lower end protection network 12 returns to the initial position of lower end.Motor 25 is connected in the rotating shaft 28 of upper end protection network 11, lower end protection network 12, controls rotating shaft 28 and move, upper end protection network 11 and lower end protection network 12 are accurately withdrawn into initial position or setting position.
Relieving mechanism 23 is used for fixing and discharging protection network.Before protection network discharges, it is possible to effectively fixed protection net.After control system 3 sends release signal, it is possible to quickly discharge protection network.For the sake of security, relieving mechanism 23 increases safety lock.Relieving mechanism 23 includes electromagnetic mechanism, when control system 3 does not send flop signal, electromagnetic block is in "on" position, now, relieving mechanism 23 passes through magnetic force, upper end protection network 11 is securely seated between upper end, lower end protection network 12 is securely seated between lower end, upper end wind spring 21 and lower end wind spring 22 all in compressive state.When control system 3 sends flop signal, electromagnetic block is in off-position, and now relieving mechanism 23 does not have magnetic force, upper end protection network 11 and lower end protection network 12 due to energy in spring, gathers to centre rapidly, closes protection network.
Control system 3 is mainly used in controlling to close closed system 2, controls to close closed system 2 and discharges protection network, reset, time delay etc.；It includes receiving terminal, PLC circuit and outfan.Receiving terminal is used for accepting the triggering signal that photocell 24 transmits；PLC circuit is used for carrying out logical judgment, time delay etc. and processes computing；Outfan is used for exporting signal, passes to relieving mechanism 23.
Fixed support 1 middle position is provided with rubber blanket 26, and rubber blanket 26 is used for protecting upper end protection network 11 and lower end protection network 12.Due to upper end protection network 11 and lower end protection network 12 when closed, speed is very fast, collides at zone line, upper end protection network 11 and lower end protection network 12 is caused bigger infringement, is simultaneously emitted by bigger sound.Increase rubber blanket 26, it is possible to effectively energy-absorbing, reduce the collision energy of upper end protection network 11 and lower end protection network 12, eliminate the sound that collision sends simultaneously.
Being provided with rail plate 27 bottom fixed support 1, rail plate 27 is used for moving whole protective net apparatus, on the one hand, according to the impact velocity of impact block 44, can suitably regulate the protection network distance to test exemplar, in order to effectively protection impact device 47；On the other hand, when installing impact block, in order to avoid protection network interferes impact block to be installed on impact device 47, it is possible to protection network entirety is moved to impact device 47, impact bar 46 is exposed, facilitates the installation of impact block 44.After completing the installation of impact block 44, then move overall for protection network equipment to test exemplar direction, adjust suitable position.
Work process of the present utility model is as follows: be illustrated in figure 3 impact test schematic diagram of the present utility model, including fixture bearing diagonal 41, fixture backboard 42, steering wheel 43, impact block 44, aloft impact block 45, impact bar 46, impacts main body 47, ferrum floor 48；This utility model device is arranged between impact device 47 and test exemplar, near impact device 47 one end, impact bar 46 is installed impact block 44, to protection network equipment power-on, by motor 25, upper end protection network 11 and lower end protection network 12 are resetted, at this moment upper end wind spring 21 and lower end wind spring 22 are in energy accumulating state, etc. signal to be triggered, then impact device 47 triggers, impact block 44 passes through protection network with certain speed, now photocell 24 sends triggering signal, control system 3 receives triggering signal, send release signal to relieving mechanism 23, relieving mechanism 23 discharges protection network, protection network quick closedown, hinder in impact block 44 bounce-back process and move to impact device 47.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
