Description
Technical field:
The utility model relates to car radar antenna connection device, is specially mobile radar antenna hydraulic locking apparatus.
Background technology
Mobile radar requires to complete at short notice reliably set up and remove receipts.Radar shipping platform arranges a kind of locking device, by hydraulic-driven, with the interlock of antenna lifting hydraulic system, can auto lock be realized, the function of servo-actuated unblock.
Utility model content:
The main purpose of this utility model is developed for dynamic radar shipping platform, and reliable lock, unlock flexibly, hydraulic-driven, the signal of telecommunication controls, and mechanical-electrical-hydraulic integration degree is high, meets the requirement of radar complete machine motorized transport and erection.
The utility model is by the following technical solutions:
Mobile radar antenna hydraulic locking apparatus, it includes pedestal, it is characterized in that: described pedestal is provided with fixed head, and pedestal one end is fixed with hydraulic jack, latch hook and grab is provided with between described fixed head, described latch hook is J type, described latch hook be provided with torsion spring between fixed head and be fixedly connected with, described latch hook is provided with loose slot, and latch hook one end is provided with roller, the latch hook other end is provided with groove a, described grab is S-type, described grab is fixedly connected with by being provided with rotational pin with between fixed head, described grab one end is connected with hydraulic jack, and the grab other end is provided with through in loose slot, described grab is provided with groove b.
Preferably, the centre of gyration line of roller and rotational pin and horizontal plane when described roller is arranged in groove b.
Operation principle of the present utility model is: when device Antenna unit is turned to final position downwards, by the rigidity locking bar on Antenna unit, in groove a in compressing latch hook, overcome the restoring torque of torsion spring, locking device is converted into locking state by released state, and in the moment reaching locking state, the stage clip in the hydraulic jack after release makes cylinder rod retract rapidly under restoring force effect, pull grab to lock latch hook, thus realize the locking to Antenna unit.
When needing to unlock, try hard to recommend dynamic cylinder rod by external hydraulic, overcome inner stage clip restoring force and stretch out, grab is unlocked latch hook, and the locking bar now on Antenna unit can depart from locking device, realizes unlocking.Latch hook turns to stroke terminal under the effect of torsion spring restoring torque, be subject to rotational pin spacing and remain open configuration, for locking action prepares next time, adopt one-way cylinder, piston rod is driven by hydraulic system when stretching out unblock, off-load during locking, makes piston reset by the stage clip effect in rod chamber.Use this oil cylinder to simplify oil circuit, be convenient to stringing.No longer rely on hydraulic system to drive (hydraulic system power-off under locking travel position) after locking, improve fail safe and the stability of mechanism.
The beneficial effects of the utility model are that this apparatus structure is simple, easy to use, the locking of hydraulic locking mechanism to antenna array relies on the self-locking property of retaining mechanism itself to realize, External Force Acting can not be produced to one-way cylinder during locking, this device locking action is simple, soon servo-actuated, can greatly shorten the radar building and withdrawing time, the restoring force of stage clip is utilized to maintain the lock status stable, the restoring torque of torsion spring is utilized to keep released state to stablize, have the advantages that locking is reliable and in stable condition, extensibility is strong, according to the difference of external applied load size suffered by locking part, contour structures can be adjusted and meet different operating mode load request.

Wherein, 1, pedestal; 2, fixed head; 3, hydraulic jack; 4, latch hook; 5, grab; 6, torsion spring; 7, loose slot; 8, roller; 9, groove a; 10, rotational pin; 11, groove b.
Embodiment
See accompanying drawing, mobile radar antenna hydraulic locking apparatus, it includes pedestal, described pedestal is provided with fixed head, and pedestal one end is fixed with hydraulic jack, latch hook and grab is provided with between described fixed head, described latch hook is J type, described latch hook be provided with torsion spring between fixed head and be fixedly connected with, described latch hook is provided with loose slot, and latch hook one end is provided with roller, the latch hook other end is provided with groove a, described grab is S-type, described grab is fixedly connected with by being provided with rotational pin with between fixed head, described grab one end is connected with hydraulic jack, and the grab other end is provided with through in loose slot, described grab is provided with groove b.
Preferably, the centre of gyration line of roller and rotational pin and horizontal plane when described roller is arranged in groove b.
When device Antenna unit is turned to final position downwards, by the rigidity locking bar on Antenna unit, in groove a in compressing latch hook, overcome the restoring torque of torsion spring, locking device is converted into locking state by released state, and in the moment reaching locking state, the stage clip in the hydraulic jack after release makes cylinder rod retract rapidly under restoring force effect, pull grab to lock latch hook, thus realize the locking to Antenna unit.
When needing to unlock, try hard to recommend dynamic cylinder rod by external hydraulic, overcome inner stage clip restoring force and stretch out, grab is unlocked latch hook, and the locking bar now on Antenna unit can depart from locking device, realizes unlocking.Latch hook turns to stroke terminal under the effect of torsion spring restoring torque, be subject to rotational pin spacing and remain open configuration, for locking action prepares next time, adopt one-way cylinder, piston rod is driven by hydraulic system when stretching out unblock, off-load during locking, makes piston reset by the stage clip effect in rod chamber.Use this oil cylinder to simplify oil circuit, be convenient to stringing.No longer rely on hydraulic system to drive (hydraulic system power-off under locking travel position) after locking, improve fail safe and the stability of mechanism.
