Detailed description of the invention
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1 ~ 5, the invention provides a kind of frame aerial of quick rising, wherein mainly comprises: the adapter plate (referred to as top board, base plate) of top and bottom; Side plate (top board and base plate all have) with chute; The hook lock device 4 (comprising hook and support) of contraction state is in for locking frame aerial; Unlock the electromagnet 2 that hook lock device 4 uses; The stock 5 of composition middle part parallelogram sturcutre and hinged round bar; For the spring providing frame aerial to raise power, be divided into extension spring 6 and Compress Spring 1; Stage clip pilot bar and compression spring sleeve.
On base plate, the side plate by band chute with bolts is fixed on base plate both sides, the hinged round bar that passes through of middle part parallel-crank mechanism inserts in chute, round bar can along slide, and extension spring 6 is hooked on the round bar of bottom, and extension spring 6 shrinks and drives frame aerial to raise.Stage clip pilot bar and compression spring sleeve are also with boltsly be arranged on base plate, the position of installing is the side of not slide with interference round bar movement, Compress Spring 1 by compression spring sleeve and stage clip pilot bar spacing, thus ensure Compress Spring 1 in restorable process all the time along frame aerial raise direction elastic force is provided.Hook lock device 4 is arranged in the middle part of base plate, the contraction state of frame aerial is ensured by the hook round bar pinned in the middle part of parallel-crank mechanism, support in hook lock device 4 is connected with base plate by bolt, and hook is by pinned connection on support, and hook can rotate around bearing pin.The electromagnet 2 providing hook lock device 4 to unlock power also uses bolt to be connected with base plate, and electromagnet core 3 uses pin to be connected on the chute of hook, and when electromagnet core 3 occurred level moves, the bearing pin that hook can be driven to be connected with support around hook rotates.The round bar of parallel-crank mechanism is inserted the side plate of top tape chute, be then fixed on top board by the side plate of bolt by band chute.The astronomical cycle that radiocommunication uses is on top board.
Frame aerial is in contraction state at ordinary times, and Compress Spring 1 is compressive state, and extension spring 6 is extended state, and two kinds of springs all have maximum power at this moment, are pinned by hook lock device 4, otherwise frame aerial will raise under the action of the spring.When frame aerial needs to open, be energized to the control electromagnet 2 that hook lock device 4 is opened, there is corresponding parallel motion in electromagnet core 3, hook is driven to rotate around the bearing pin be connected with support, after the round bar of hook completely and in the middle part of parallel-crank mechanism departs from, frame aerial top board is first upspring certain altitude by Compress Spring 1, and following extension spring 6 continues shrink thus frame aerial is raised.
In above-mentioned frame aerial, the stock of composition parallelogram sturcutre adopts stainless steel square pipe to make, and hinged pipe uses stainless pipe to make; The side plates of hook lock device 4, compression spring sleeve, stage clip pilot bar, top board, base plate, band chute etc. use aluminum alloy to be made.Due to a kind of boats and ships signal projector with automatic rescue alarm device in danger is use across the sea, antenna needs to rise from water, the impact of rising on frame aerial in order to the resistance reducing water in uphill process is too large, reduces the resistance of water in frame aerial elevation process by the mode of holing on frame aerial top board.
Reference accompanying drawing 1 is the frame aerial integral structure schematic diagram that the present invention raises fast; As shown in Figure 2, when being energized to electromagnet 2, electromagnet core 3 is subject to the magnetic force that magnet coil produces to hook lock device initial condition, is moved to the left at shown position, and band moveable lock hook 4, around fulcrum, realizes the unblock of frame aerial, as shown in Figure 3.After the round bar pinned when latch hook 4 departs from completely, due to the existence of Compress Spring 1 and extension spring 6, the power that the elastic force of spring will be converted to frame aerial and rises, realizes the conversion of elastic potential energy to gravitional force.Its implementation procedure is that frame aerial is first upspring certain height by Compress Spring 1, and the pulling force that the extension spring of bottom is provided is enough to drive the normal rising of frame aerial at the component of frame aerial vertical direction.Because extension spring 6 one end is fixed, one end is fixed on the round bar that can slide in chute in addition, so round bar can be driven to slide when extension spring 6 shrinks.Form middle part parallelogram sturcutre by 12 stocks 5, by the horizontal motion of bottom round bar, drive the rising of whole frame aerial.As shown in Figure 4, after rising completely, state as shown in Figure 5 for contraction state.
After hook lock device unlocks, the Main Function of Compress Spring 1 is to provide the initial driving force that frame aerial rises, although the pulling force that major cause is extension spring 6 is maximum at initial condition, but extension spring 6 component of vertical direction that can provide is very little in an initial condition for frame aerial, so adopt Compress Spring 1 to be supplied to the initial speed of frame aerial one, ensure that frame aerial normally rises, guarantee that extension spring 6 can play the effect that frame aerial is raised.After frame aerial thoroughly raises, because bottom extension spring 6 still has certain pulling force, can ensure that frame aerial raises rear self-locking, height can not change.
