Specific embodiment
As Figure 1-3, including frame 1, the top of the frame 1 is provided with the reel 3 driven by motor 2 to the present invention,
Fixed pulley group 4 is provided with frame 1, the bottom of the frame is provided with equalizer pulley 5, running block 6 is provided with below the frame,
Reel is respectively arranged at two ends with support shaft 10, and motor 2 connects a support shaft of reel, another support of reel by reductor 9
Axle is connected in frame by bearing block 11 so that reel rotation is reliable；
The two ends of the reel 3 are wound by same steel wire rope 7 with running block 6, fixed pulley group 4 and equalizer pulley 5 respectively
Connection；The order of connection of steel wire rope is：Reel → running block → one → running block of fixed pulley → equalizer pulley → movable pulley
Group → two → running block of fixed pulley → reel.
The center line of the center line, the center line of fixed pulley group and running block of the reel 3 is parallel and positioned at same
In plane.
Prior art as shown in fig. 6, A be drum center line, B is perforate, and reel and fixed pulley are arranged side by side；And it is of the invention
As shown in fig. 7, C is the center line of drum center line, the center line of fixed pulley group and running block, reel is being located at fixed pulley just
Top, this structure type causes that whole machine plane projection area reduces, and width reduces half or so, and this arrangement form can be reduced
Headstock gear integral arrangement size, reduces cost saves installing space；Meanwhile, the form arranged up and down plays fixed pulley group
Dust-proof effect.
The equalizer pulley 5 is connected in frame by suspension bracket 8, and the central axis of the equalizer pulley are in fixed pulley group
Center line, so, the surfaces of revolution of the surfaces of revolution of equalizer pulley perpendicular to fixed pulley so that wirerope-winding reliability.
The fixed pulley group 4 includes riser 41, the fixed pulley 42 of a pair of parallel setting of a pair of parallel setting（That is fixed pulley
One and fixed pulley two）With a trunnion axis 43, a pair of risers are located in frame, and the trunnion axis is connected on a pair of risers, a pair
Fixed pulley is set on the horizontal axis and between a pair of risers.Set on the horizontal axis by by a pair of fixed pulleys, trunnion axis is passed through
A pair of risers, convenient connection installs reliable.
In the same plane, the equalizer pulley 5 is located between a pair of fixed pulleys 42, as shown in Fig. 2 in actual installation,
Equalizer pulley and fixed pulley group stagger settings so that wirerope-winding reliability, it is to avoid interfere.
The diameter with diameter greater than fixed pulley 42 of the reel 3, it is to avoid interference so that wirerope-winding is smooth, and action can
Lean on.
As shown in Fig. 2 in the same plane, the included angle A between the steel wire rope of fixed pulley and reel homonymy is equal to fixed pulley
And the included angle B between the steel wire rope of equalizer pulley homonymy, included angle A and included angle B are respectively positioned at the both sides of fixed pulley so that reel,
