The two ends of the screw 230 are rotatably connected to the support plate 210 and the support plate 220, respectively, and the axial direction of the screw 230 is perpendicular to the support plate 210 and the support plate 220, i.e., the axial direction of the screw 230 is parallel to the axial direction of the traction roller 120. Bearings matched with the screw 230 are respectively arranged in the supporting plate 210 and the supporting plate 220 so as to facilitate the rotation of the screw 230; wherein, the right end of the screw 230 passes through the bearing of the support plate 210 and extends to the right side of the support plate 210. The nut 240 is mounted on the lead screw 230 in a matching manner, and is combined with the lead screw 230 to form a lead screw nut pair. The second synchronous pulley 250 is coaxially and fixedly connected to the right end of the lead screw 230 and is positioned on the right side of the support plate 210; and the installation position of the second timing pulley 250 is flush with the installation position of the first timing pulley 140 in the vertical direction. The second timing pulley 250 and the first timing pulley 140 are driven by a belt 250 a.
Preferably, the screw 230 is a single-rotation reciprocating screw, and the nut 240 is matched with the screw; in this way, when the screw 230 is rotated in the same direction, the nut 240 moves to one end of the screw 230 and then returns to the other end of the screw 230, that is, the nut 240 reciprocates when the screw 230 is rotated in one direction.
The guide bar 260 is disposed above the lead screw 230 in parallel, and both ends of the guide bar 260 are fixedly coupled to the support plate 210 and the support plate 220, respectively. The lower end of the rope moving mechanism 270 is fixedly connected to the nut 240; the upper end is movably arranged on the guide rod 260; the pulling rope 130 movably passes through the rope moving mechanism 210 and can move along the axial direction of the lead screw 230 under the driving of the rope moving mechanism 210.
As shown in fig. 4, in the present embodiment, the rope moving mechanism 270 includes: the mounting seat 271 is fixedly connected to the nut 240; a guide sleeve 272 movably fitted over the guide bar 260; the 4 optical axes 273 are vertically arranged, and the upper end and the lower end of each optical axis 273 are respectively and fixedly connected to the mounting seat 271 and the guide sleeve 272; the 4 optical axes 273 are divided into two left and right rows, and the traction rope 130 passes through between the two left and right rows of optical axes 273. The pull cord 130 is a clearance fit with the optical axis 273.

In addition, the diameters of the second synchronous pulley 250 and the first synchronous pulley 140 can be set according to the diameter of the traction drum 120 and the diameter of the traction rope 130, so that when the traction rope 130 winds around the traction drum 120 for one turn, the moving distance of the nut 240 is just equal to the diameter of the traction rope 130, thereby ensuring that the traction rope 130 is tightly arranged on the traction drum.
The working process of the traction device for the hoisting trolley comprises the following steps:
the speed reducing motor 110 is started to drive the traction drum 120 and the first synchronous pulley 140 to synchronously rotate, and under the action of the belt 250a, the second synchronous pulley 250 rotates to drive the lead screw 230 to rotate, so that the nut 240 moves along the axial direction of the lead screw 230, and as the traction rope 130 is clamped in the middle of the rope moving mechanism 270, the rope moving mechanism 270 moves along the nut 240, so that the traction rope 130 is driven to uniformly arrange along the axial direction of the traction drum 120 while moving around the traction drum 120; because a single-rotation reciprocating screw-nut mechanism is adopted; when the lead screw 230 keeps rotating in one direction, the nut reaches one end of the lead screw 230 and then can move in the opposite direction, so that the traction rope 130 is uniformly wound on the traction drum 120 layer by layer. The condition that the traction rope is intensively wound at the middle part of the traction roller 120 to slide is avoided, so that the operation process of the traction device is more stable.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
