Examples

Referring to fig. 1-3, a take-up stand elevating gear, includes two stands 1, the take-up stand is including locating the take-up reel utensil 2 between two stands 1, the rotation is equipped with the lead screw 3 of vertical direction on the stand 1, lead screw 3 is connected with elevator motor 4, and threaded connection has lifting nut 5 on the lead screw 3, be equipped with radial convex connecting block 6 on the lifting nut 5, the both ends of taking-up reel utensil 2 all are connected with pivot 7, pivot 7 rotates and connects on lift slide 8, lift slide 8 just is connected with connecting sleeve 9 along vertical direction sliding fit with stand 1 of its homonymy, connecting sleeve 9 locates its lift nut 5 outsides that corresponds and is equipped with the spread groove 10 with connecting block 6 clearance fit on it.

Be equipped with holding tank 11 on the stand 1, lead screw 3 is located in holding tank 11, elevator motor 4 fixes on stand 1 and is connected with 3 tops of lead screw.

The lifting slide 8 is provided with a sliding part 12 vertically matched with the accommodating groove 11 in a sliding manner, and the sliding part 12 is provided with a through hole 13 for the lead screw 3 to penetrate through.

The both sides of stand 1 all are equipped with the slide rail 15 of vertical direction, and equal sliding fit is equipped with top sheave 16 and lower pulley 17 in every slide rail 15, top sheave 16 locates the top of lift slide 8, the below of lift slide 8 is located to lower pulley 17, and top sheave 16, lower pulley 17 all rotate with lift slide 8 through connecting plate 18 and are connected. In the present exemplary embodiment, four connecting plates 18 are provided and are fastened to the lifting carriage 8.

Four connecting blocks 6 are uniformly arranged on the lifting nut 5 along the circumferential direction, and the number and the positions of the connecting grooves 10 on the connecting sleeve 9 correspond to the connecting blocks 6.

One of the rotating shafts 7 of the wire take-up reel 2 is connected with a wire take-up motor 14, and the wire take-up motor 14 is fixed on the corresponding lifting slide 8.

The utility model discloses a theory of operation does: the take-up motor 14 drives the take-up reel 2 to rotate to take up the cable. The lifting motor 4 drives the screw rod 3 to rotate, the lifting nut 5 is controlled to lift, the lifting nut 5 drives the connecting sleeve 9 and the lifting slide seat 8 connected with the connecting sleeve 9 to lift through the connecting block 6, and therefore the height of the take-up reel 2 is adjusted.

The utility model discloses in, lift nut 5 drives lift slide 8 through connecting block 6 and goes up and down, use when lead screw 3 for a long time and take place slight deformation, when lead screw 3's axial takes place to deflect, because connecting block 6 is clearance fit with spread groove 10, lift nut 5 has certain activity space, lift nut 5 can slightly deflect in adapter sleeve 9, consequently lift nut 5's lift direction is along with lead screw 3 synchronous deflection, and lift slide 8 continues to go up and down along vertical direction because the guide effect of sliding part 12 and pulley (top sheave 16 and lower pulley 17) slide rail is under lift nut 5's drive.
