Description
Technical field
The present invention relates to a kind of mast draw off gear that is used on the military or civilian motor-driven communication van, specifically a kind of mast folding and unfolding lodging mechanism.
Background technology
On military, civilian communication vehicle, be used for settling the installing rack of mast when not using, vertically to be placed in usually outside the squab panel in compartment, when antenna uses, need make the top of installing rack lodging in the compartment.Pack up and lodge for installing rack and settle operation; What generally all adopt is to move the convertible mechanism of formula, lift-on/lift-off type or steel wire rope; The general problem of using these modes is exactly inconvenient operation, poor stability; And need the aid dismounting and build, be difficult to satisfy convenience requirement the mast folding and unfolding.
Summary of the invention
The technical problem that the present invention will solve provides the mast folding and unfolding lodging mechanism of a kind of simple in structure, easy for operation, fail safe and installation highly versatile.
In order to solve the problems of the technologies described above; Mast folding and unfolding of the present invention lodging mechanism; Include the installing rack and lodging frame of the bar that is used for fixing up an aerial wire; Motor is installed and by motor-driven gear, the tooth bar that is meshed with said gear is installed on the installing rack on the lodging frame, installing rack can move at the guide rail straight line on the driving lower edge of the pinion and rack lodging frame; Said lodging chord position is in the angle of cut outside of car body top and rear wall, and lodging frame and compartment outer wall are hinged and can swing around jointed shaft, make its guide rail be positioned at horizontal level or vertical position; Said installing rack hypomere hinged inside has one section push rod, between push rod and the installing rack spring is installed, and spring force makes the free end of push rod swing and rely on the installing rack medial surface to the jointed shaft top; Said compartment squab panel outer upper is provided with a block, and block is positioned on the route that the free end of said push rod vertically moves and can stops that the free end straight line of push rod moves up.
Said car body top is provided with the mobile bracing frame that is positioned at lodging frame the place ahead, and mobile bracing frame can move forward and backward along the guide rail on the compartment top board; When the guide rail of lodging frame lodged to level, said installing rack previous paragraphs was moving on the bracing frame, and moved with mobile bracing frame is together forward and backward.
The torsion spring that lodging process to the lodging frame cushions is installed on the jointed shaft of said lodging mechanism.
The present invention utilizes the variation of center of gravity in the installing rack moving process, the auxiliary power that makes the deadweight of installing rack become its lodging or hold up, and its power consumption is little, simple in structure, easy to operate, operate steadily; Its whole device is placed in the outside, compartment, and space hold is little, applicable different vehicles type, highly versatile.

Embodiment
Below in conjunction with accompanying drawing and embodiment, mechanism does further explain to mast folding and unfolding of the present invention lodging.
As shown in Figure 1; Mast folding and unfolding of the present invention lodging mechanism includes the installing rack 1 and lodging frame 2 of the bar that is used for fixing up an aerial wire; Lodging is equipped with motor on the frame 2 and by motor-driven gear; The tooth bar that is meshed with said gear is installed on the installing rack 1, and installing rack 1 can move at the guide rail straight line on the driving lower edge of the pinion and rack lodging frame; Lodging frame 2 is positioned at the angle of cut outside of 6 tops, compartment and rear wall, and lodging frame 2 is hinged with the compartment outer wall and can swings around jointed shaft, makes its guide rail be positioned at horizontal level or vertical position; Said installing rack 1 hypomere hinged inside has one section push rod 4, between push rod 4 and the installing rack 1 spring is installed, and spring force makes the free end 41 of push rod swing and rely on the installing rack medial surface to the jointed shaft top; Compartment squab panel outer upper is provided with a block 3, and block is positioned on the vertically mobile route of said free end 41 and can stops that free end 41 straight lines of push rod move up.
When not using antenna, the installing rack state is as shown in Figure 1, vertically is positioned at the squab panel outside, compartment.
When needs drive installation frame gets into the lodging state, whole course of action such as Fig. 2～shown in Figure 5:
At first installing rack 1 moves (like Fig. 2) straight up under the driving of pinion and rack;
In the installing rack moving process, after the free end 41 of push rod 4 touched block 3, under the stopping of block 3, push rod began to rotate and is supporting installing rack and begins rotation and depart from vertical position (like Fig. 3) gradually with the lodging frame;
When installing rack 1 continued to move to its center of gravity and cross the jointed shaft of lodging frame along the guide rail on the lodging frame, installing rack 1 began under the effect of its deadweight from trend lodging rotated position, and makes the free end 41 of push rod break away from blocks 3 (like Fig. 4);
Finally, installing rack lodges to horizontal level under the effect of deadweight, and the continuation straight line moves to service position (like Fig. 5).
As shown in the figure, car body top is provided with the mobile bracing frame 5 that is positioned at lodging frame the place ahead, and mobile bracing frame can move forward and backward along the guide rail on the compartment top board; When the guide rail of lodging frame 1 lodged to level, the previous paragraphs of installing rack 1 was on mobile bracing frame 5, and under Fig. 5 state, installing rack moves forward under the support of moving bracing frame.The torsion spring that cushions of lodging process to the lodging frame is installed on the jointed shaft of lodging mechanism.
When antenna did not use, the process of packing up of installing rack was opposite with above-mentioned lodging process.
