As shown in Figure 1-Figure 4:

on the one hand:

The present invention discloses an expansion anti-winding traction device, comprising a gantry 1, a winding machine installed on the gantry 1 and having two groups of wires wound on the winding drum, a hoisting mechanism 3 connected to the two groups of wires respectively, a fixed pulley 4 installed in cooperation with one of the groups of wires, and a guide pulley group 5 used for guiding the two groups of wires and arranged one by one; the hoisting mechanism 3 is located between the fixed pulley 4 and the guide pulley group 5;

One set of wires passes through the corresponding guide pulley set 5 and is connected to the side of the hoisting mechanism 3 away from the fixed pulley 4;

Another group of wires passes through the corresponding guide pulley group 5 and the hoisting mechanism 3 in sequence, bypasses the fixed pulley 4, and is connected to the side of the hoisting mechanism 3 away from the fixed pulley 4.

Before use, one set of wires is passed through the corresponding guide pulley block 5, the hoisting mechanism 3 and wound around the outside of the fixed pulley 4, and then connected to the side of the hoisting mechanism 3 away from the door frame 1, and the other set of wires is passed through the corresponding guide pulley block 5, and then connected to the side of the hoisting mechanism 3 close to the door frame 1;

The setting of the guide pulley group 5 will effectively achieve the guidance and anti-slipping of the corresponding set of wires; before traction, the product to be towed is connected to the lifting mechanism 3, and then the winch 2 is used to control the drum to rotate clockwise or counterclockwise around its axis, so as to achieve a linear movement of the product to be towed close to or away from the gantry 1.

Compared with the prior art, the present invention only needs one set of winches 2 and two sets of cables to realize the linear reciprocating motion of the product to be towed, thereby reducing the use of one set of winches 2 and the construction cost; the structure is simple and the usability is strong.

In some possible implementations, in order to effectively realize the connection between the two sets of threads and the hanging mechanism 3 respectively;

The thread includes a thread 10 wound on the drum in a clockwise direction and a thread 20 wound on the drum in a counterclockwise direction; one end of the thread 10 passes through the guide pulley group 5 and the lifting mechanism 3 in sequence and then bypasses the fixed pulley 4 and is connected to the lifting mechanism 3 close to the fixed pulley 4, and one end of the thread 20 is connected to an end of the lifting mechanism 3 away from the fixed pulley 4.

In some possible implementations, in order to effectively guide and prevent the two groups from falling off;

The guide pulley groups 5 are two groups and are arranged corresponding to the two groups of wires 10. The two groups of guide pulley groups 5 are coaxially arranged and on the same plane.

The guide pulley group 5 includes an anti-slip device 51 that rotates vertically and is connected to the door frame 1, and a line dividing pulley 52 that is installed on the door frame 1 and located above the anti-slip device 51; one end of the line 10 or the line 2 20 passes through the anti-slip device 51 and is wrapped around the outside of the line dividing pulley 52.

In some possible implementations, in order to effectively prevent the wires from falling off and ensure that the two sets of wires will not be entangled with each other;

The anti-slip device 51 comprises a pin shaft 511 which is installed on the door frame 1 and is arranged vertically, a support seat 512 which is sleeved on the pin shaft 511 and rotatably matched with the pin shaft 511 , and a pulley 513 which is installed on the support seat 512 .

Preferably, the line dividing pulley 52 is located directly above the anti-slip device 51 , and its axis is arranged parallel to the axis of the pulley 513 .

The pin 511 is vertically arranged perpendicular to the axis of the pulley 513. During use, the pulley 513 can swing freely with the swing amplitude of the cable through the rotational cooperation of the two, thereby avoiding an angle between the cable and the pulley 513 of the anti-drop device 51, so that the cable falls off from the corresponding pulley 513 during operation.

The axis of the pulley 513 and the axis of the drum are parallel to each other and on the same horizontal plane. The distance between the two axes is L. The length of the drum for winding two sets of threads is B.

Among them, L≥(B*tan10°)/2.

By controlling the distance between the drum and the pulley 513 in the anti-slip device 51, the cable swing amplitude is effectively controlled within a range of 10 degrees, thereby preventing the traction cable from winding itself, that is, winding more than two layers around the drum.

By controlling the distance between the drum and the pulley 513 in the anti-slip device 51 and controlling the pulley 513 to swing with the corresponding cable, the cable will only be wound around the drum in one layer during use, so that the cable can be retracted and released in equal length.

In some possible implementations, in order to effectively ensure that the connecting section 200 of the first cable 10 and the second cable 20 will not be entangled during use, and to enable it to always be wound on the surface of the reel during use, only one layer of structure is provided, thereby ensuring that the two sets of cables can achieve the same retracted and released lengths on the reel during use;

The winding section 100 is a layer; the distance between the winding section 100 of the first thread 10 and the winding section 100 of the second thread 20 is A, the diameter of the thread is d, and A≥5d.

Both the first thread 10 and the second thread 20 are wound on the drum in one layer, that is, the winding section 100 is one layer. There is a certain distance A between the winding sections 100 of the two groups of threads. The purpose of setting this distance is to enable the tightened connecting sections 200 to be wound on the surface of the drum and form a layer structure when they are initially retracted and released; in this way, the retracted and released lengths of the two groups of cables can be equal; when the two groups of threads are wound, the winding sections 100 of the two groups of threads are wound from the two ends of the drum to the middle of the drum.

In some possible implementations, in order to effectively achieve the traction of the product to be traction;

The hoisting mechanism 3 includes a pulley block which is respectively connected to a frame with the first cable 10 and the second cable 20, installed in the frame and slidingly cooperates with the first cable 10.

The thread 10 is wound around the drum in a clockwise direction, passes through the upper side of the drum, passes through the bottom of the corresponding pulley 513, and then is wound around the dividing pulley 52 and guided by the dividing pulley 52, so that the free end of the thread 10 can pass through the pulley block of the lifting mechanism 3 and pass through the fixed pulley 4. After being guided, it is connected to the side of the hoisting mechanism 3 away from the gantry 1;

The second thread 20 is wound around the drum counterclockwise, passes through the bottom of the drum, and passes through the bottom of the corresponding pulley 513, and then is wound around the split line pulley 52 and guided by the split line pulley 52, and connected to the side of the hoisting mechanism 3 close to the door frame 1;

When in use, the hoisting mechanism 3 is connected to the product to be towed;

When the drum is controlled by the winch 2 to move clockwise along its axis, the first thread 10 is released, and the second thread 20 is tightened and wound around the drum, thereby realizing the movement of the hoisting mechanism 3 to the side close to the gantry 1;
