Slot is equipped with sliding block, and sliding block side is equipped with tensioner wheel assembly, and the sliding block other side is equipped with movable pulley；The two of the guide chute bottom
Side is additionally provided with the second fixed pulley and fixed ring；Fixed ring and hook between be equipped with tensioner rope, and tensioner rope sequentially pass through movable pulley,
Second fixed pulley and the first fixed pulley.
In a kind of high-adaptability elevator speed limit tensioning device above-mentioned, it is equipped between first fixed pulley and pit metope
Fixed frame.
In a kind of high-adaptability elevator speed limit tensioning device above-mentioned, the leading truck is L-type structure, leading truck bottom surface warp
Bolt is mutually fixed with bottom case ground.
In a kind of high-adaptability elevator speed limit tensioning device above-mentioned, the limit carriage side wall is equipped with safety switch,
The upper end of clump weight side wall is equipped with the switch matched with safety switch and re-packs.
In a kind of high-adaptability elevator speed limit tensioning device above-mentioned, the tensioner wheel assembly is equipped with limiter of speed steel wire
Rope.
In a kind of high-adaptability elevator speed limit tensioning device above-mentioned, the both ends of the clump weight bottom are equipped with baffle, gear
Plate is equipped with cushion, and spring is equipped between cushion and baffle.
Compared with prior art, the present invention is existed by the first fixed pulley, clump weight and setting being arranged on pit metope
Leading truck, movable pulley, the second fixed pulley and fixed ring composition on pit ground, and above-mentioned component is connected by tensioner rope,
There is counterweight in tensioner rope one end system, to give one downward expanding force of tensioner wheel assembly, reaches the effect of speed limiter wire rope tensioner
Fruit；Using the above structure, not only structure structure, it is flexible for installation, and the spare space of hoistway can be utilized to greatest extent,
The requirement for hoistway installation space is reduced, shallow pit hoistway had both been able to satisfy, and had also been able to satisfy small size hoistway；It simultaneously can also be
The weight of clump weight is largely reduced, and then can also reduce the volume of clump weight.Meanwhile the present invention passes through in leading truck
Upper setting guide chute drives movable pulley to move up and down, in the effect of clump weight by the mutual cooperation of sliding block and guide chute
Under, enable movable pulley difference of expanding force size according to suffered by tensioner wheel assembly and is automatically adjusted accordingly, from
And optimal tensioner state can be in real-time ensuring, additionally it is possible to improve the scope of application.In conclusion the present invention can effectively drop
The low requirement for hoistway installation space.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of high-adaptability elevator speed limit tensioning device is constituted as shown in Figure 1 to Figure 3, including is arranged in pit
The first fixed pulley 1 on metope is equipped with the limit balladeur train 2 being fixed on pit metope below the first fixed pulley 1, limits balladeur train 2
Interior to be equipped with clump weight 3,3 upper end of clump weight is equipped with hook 4；It further include the leading truck 5 being arranged on pit ground, on leading truck 5
Equipped with guide chute 6, guide chute 6 is equipped with sliding block 7, and 7 side of sliding block is equipped with tensioner wheel assembly 8, and 7 other side of sliding block is equipped with dynamic
Pulley 9；The two sides of 6 bottom of guide chute are additionally provided with the second fixed pulley 10 and fixed ring 11；Between fixed ring 11 and hook 4
Equipped with tensioner rope 12, and tensioner rope 12 sequentially passes through movable pulley 9, the second fixed pulley 10 and the first fixed pulley 1.
Fixed frame 13 is equipped between first fixed pulley 1 and pit metope.
The leading truck 5 is L-type structure, and 5 bottom surface of leading truck is mutually fixed through bolt and bottom case ground.
2 side wall of limit balladeur train is equipped with safety switch 14, and the upper end of 3 side wall of clump weight is equipped with and 14 phase of safety switch
The switch of cooperation re-packs 15.
The tensioner wheel assembly 8 is equipped with speed limiter wire rope 16.
The both ends of 3 bottom of clump weight are equipped with baffle 301, and baffle 301 is equipped with cushion 302, cushion 302 and gear
