The hoist can drag the heavy object vertically, horizontally or obliquely. The winding machine is divided into a manual winding machine and an electric winding machine. Electric winches are now the main. Can be used independently, can also be used as a component part in machinery such as hoisting, road building, mine hoisting and the like, and is widely applied due to simple operation, large rope winding amount and convenient displacement.

The application provides a core-pulling device for a polymerization machine, which is used for pulling out a rotor 010 of the polymerization machine, and as shown in fig. 1, the core-pulling device comprises a frame 100, a bracket 200 and a winch 300, wherein the frame 100 is used for supporting the bracket 200 and the winch 300, and the frame 100 may be generally formed by welding profiles, such as square tubes, channel steel and the like, without limitation. A horizontal sliding rail 110 is disposed above the frame 100, and the horizontal sliding rail 110 may be a linear guide rail, a linear sliding chute, or the like, but is not limited thereto.

The bracket 200 is slidably connected to the horizontal sliding rail 110, the upper surface of the bracket 200 is a double arc groove 210, the double arc groove 210 is used for supporting the screws, and the shape of the double arc groove 210 is similar to the arc shape of the double screws of the rotor 010 of the polymerizer, i.e., the two arcs of the double arc groove 210 are also arranged along the radial direction.

The winch 300 is disposed on the frame 100 and connected to the bracket 200 through a wire rope 310, so that the bracket 200 is driven by the wire rope 310 to move along the horizontal sliding path 110 when the winch 300 is operated.

Compared with the prior art, the core pulling device for the polymerization machine comprises the frame 100, the bracket 200 and the winch 300, and the bracket 200 can move along the frame 100 in the horizontal direction. The bracket 200 is provided with a double arc-shaped groove 210 above for supporting the rotor 010 of the polymerizer. The winding machine 300 can provide a driving force for the bracket 200 to horizontally move the bracket 200 along the rack 100, so that the rotor 010 of the polymerization machine moves along the rack 100 under the support of the bracket 200, thereby achieving the purpose of withdrawing the rotor 010. In this process, the rotor 010 is supported by the bracket 200, the number of operators is reduced, the working strength of the operators is reduced, and the working efficiency is improved.

In order to increase the friction force between the double-arc-shaped groove 210 and the double screws and avoid slipping, in some embodiments, the anti-slip layer 400 is arranged on the double-arc-shaped groove 210, and the anti-slip layer 400 increases the friction force between the double-arc-shaped groove 210 and the double screws, so that the double screws can move along the rack 100 along with the bracket 200 more easily, and the core pulling purpose is achieved.

In addition, in order to protect the twin-screw and avoid abrasion, the anti-slip layer 400 can be made of soft materials, such as rubber, nylon and the like, so that abrasion caused by contact between the twin-screw and the anti-slip layer 400 is avoided, and the maintenance cost is increased.

In order to facilitate the movement of the bracket 200 along the horizontal sliding path 110, in some embodiments, as shown in fig. 1, a roller bracket 500 is disposed at the bottom of the bracket 200, a roller 510 is disposed on the roller bracket 500, the roller 510 is located in the horizontal sliding path 110, and the movement of the bracket 200 along the rack 100 is realized through the roller 510, which is simple in structure and low in cost.

In use, the bracket 200 generally requires height adjustment to provide better support for the double arc groove 210 and the twin screw. In some embodiments, as shown in fig. 2, the bracket 200 is provided with a through hole 220, the roller bracket 500 is provided with a lead screw 520, the lead screw 520 penetrates through the through hole 220, an adjusting nut 530 is arranged between the bracket 200 and the roller bracket 500, the adjusting nut 530 is matched with the lead screw 520, and the adjusting nut 530 abuts against the lower surface of the bracket 200, so that when the adjusting nut 530 is rotated to ascend or descend along the lead screw, the adjusting nut 530 can bring the bracket 200 to ascend or descend together, thereby achieving the purpose of adjusting the height of the bracket 200, and the structure is simple and convenient to adjust.

In some embodiments, as shown in fig. 2, there are two roller brackets 500, and the two roller brackets 500 are spaced apart in a horizontal direction perpendicular to the horizontal sliding path 110. Correspondingly, the number of the horizontal slide way 110, the number of the screw rods, the number of the adjusting nuts and the like are also two, and the description is omitted.

The supporting leg 800 can be moved along the frame 100 by a motor, an air cylinder, etc., and is not limited herein.

In order to further increase the firmness between the rack 100 and the ground, in some embodiments, as shown in fig. 1, a fixing device 900 is disposed at an end of the rack 100 close to the polymerizer (not shown), and the fixing device 900 is used to fix the rack 100 to the polymerizer, so that the rack 100 and the polymerizer are fixed, thereby increasing the firmness between the rack 100 and the ground and preventing movement.

When the core pulling device for the polymerization machine is used for pulling out the rotor 010, the rack 100 is fixed, the steel wire rope 310 of the winch 300 is adjusted to penetrate through the guide wheel 600 on the right side, then an operator manually pulls out the rotor 010 for a section, then a bracket 200 is placed, the height of the bracket 200 is adjusted to support the rotor 010, the winch 300 is started, the rotor 010 moves outwards under the power of the winch 300, after the rotor 010 moves for a certain distance, the bracket 200 can be placed again, the height is adjusted, and the rotor 010 is pulled out step by step in such a circulating mode.
