Description

Technical Field

[0001] The present invention relates to the field of threading ropes through hollow tubes, and more particularly to a rope threading device and a rope threading method. Background Art

[0002] Threading a rope through a hollow tube has always been an important problem in the industry. Among them, threading a rope through a hollow hard tube is relatively easy to solve. The method is to hook the rope to be threaded at one end of a long steel wire, and then use the steel wire to pull the rope hooked at its tail end through the hollow hard tube, thus completing the rope threading.

[0003] However, due to its soft material, when the length of the hollow flexible tube is relatively long, it is easy for the hollow flexible tube to bend and block the rope threading. Therefore, how to achieve rope threading through a relatively long hollow flexible tube has become an urgent problem to be solved in the industry. Summary of the Invention

[0004] Based on this, it is necessary to provide a rope threading device that can solve the above problems.

[0005] In addition, it is also necessary to provide a rope threading method using the above rope threading device.

[0006] A rope threading device for threading a rope into a hollow tube, comprising:

[0007] A plurality of support frames for placing the hollow tube;

[0008] A track provided on the support frame;

[0009] A retracting device movably provided on the track. The lower end of the retracting device passes through the track and is arranged above the support frame. A connecting column matching the hollow tube is provided at the lower end of the retracting device. The connecting column is used to be sleeved inside the end of the hollow tube. The retracting device moves along the track, thereby placing the hollow tube on the support frame;

[0010] A floating ball with a diameter smaller than the inner diameter of the hollow tube, and the floating ball is connected to one end of the rope;

[0011] A negative pressure device having a suction end. The suction end and the floating ball are respectively used to be connected to both ends of the hollow tube. After the negative pressure device is started, the suction end sucks air, thereby sucking the floating ball into the hollow tube and driving the rope to move. The floating ball moves inside the hollow tube until it moves to the suction end.

[0012] In one embodiment, a clamping device that moves relative to the connecting column is further provided at the lower end of the retracting device. When the end of the hollow tube is sleeved outside the connecting column, the clamping device moves relative to the connecting column until the clamping device, the end of the hollow tube, and the connecting column are sequentially in contact, thereby clamping the end of the hollow tube.

[0013] In one embodiment, the clamping device has an operating member and a clamping member. The operating member is used to control the clamping member to approach or move away from the connecting column, and the clamping member is used to contact the end of the hollow tube.

[0014] In one embodiment, the retracting device includes a main body and a vertical rod. There are two tracks that are parallel to each other and spaced apart. The lower end of the vertical rod passes through the middle of the two tracks and is arranged above the support frame, and the connecting column is arranged at the lower end of the vertical rod.

[0015] In one embodiment, the vertical rod can move up and down relative to the main body, thereby driving the connecting column to move up and down relative to the main body.

[0016] In one embodiment, the retracting device further includes a horizontal pulley arranged at the lower end of the main body and a vertical pulley arranged on the side surface of the main body. The horizontal pulley is connected to the side surface of the track, and the vertical pulley is connected to the upper surface of the track.

The track is clamped between the two groups of horizontal pulleys, and a long strip-shaped groove matching the horizontal pulley is further provided on the side surface of the track.

[0018] In one embodiment, the rope threading device further includes a winding device for winding the hollow tube through which the rope body passes.

[0019] A rope threading method includes the following steps:

[0020] Provide a hollow tube, a rope body, and the above-mentioned rope threading device;

[0021] Set the end of the hollow tube outside the connecting column, and the retracting device moves along the track, thereby placing the hollow tube on the support frame;

[0022] Connect the floating ball to one end of the rope body, and then connect the suction end and the floating ball to the two ends of the hollow tube respectively;

[0023] After the negative pressure device is started, the suction end sucks air, thereby sucking the floating ball into the hollow tube and driving the rope body to move. The floating ball moves in the hollow tube until it moves to the suction end, thus completing the threading of the rope.

[0024] In one embodiment, a clamping device that moves relative to the connecting column is further provided at the lower end of the pulling device;

[0025] The rope threading method further includes the following operations after the operation of sleeving the end of the hollow tube outside the connecting column and before the operation of the pulling device moving along the track:

[0026] The clamping device moves relative to the connecting column until the clamping device, the end of the hollow tube, and the connecting column are sequentially in contact, thereby realizing clamping of the end of the hollow tube.

[0027] When the rope threading device of the present invention is in use, the end of the hollow tube is sleeved outside the connecting column, and the pulling device moves along the track, thereby placing the hollow tube on the support frame; connect the floating ball to one end of the rope body, and then connect the suction end and the floating ball to the two ends of the hollow tube respectively; after the negative pressure device is started, the suction end sucks air, thereby sucking the floating ball into the hollow tube and driving the rope body to move. The floating ball moves in the hollow tube until it moves to the suction end, thus completing the threading of the rope.

[0028] When the rope threading device of the present invention is used for threading a hollow flexible hose, even if the hollow flexible hose is bent to block the rope threading due to its long length, it does not affect the movement of the floating ball in the hollow flexible hose, so that the threading of a relatively long hollow flexible hose can be realized.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In conjunction with Figure 1 , the present invention discloses a string threading device of an embodiment, which is used to thread a rope body 200 into a hollow tube 300, and includes: a plurality of support frames 10, a track 20, a pulling device 30, a floating ball 40, and a negative pressure device 50 having a suction end 52.

[0038] The support frame 10 is used to place the hollow tube 300, and the track 20 is arranged on the support frame 10.

[0039] In conjunction with the accompanying drawings, in this embodiment, a plurality of support frames 10 are arranged at intervals from each other.

[0040] In conjunction with Figure 2 , the pulling device 30 is movably arranged on the track 20. The lower end of the pulling device 30 passes through the track 20 and is arranged above the support frame 10. And a connecting column 32 matching the hollow tube 300 is provided at the lower end of the pulling device 30. The connecting column 32 is used to be sleeved inside the end of the hollow tube 300. The pulling device 30 moves along the track 20, so as to place the hollow tube 300 on the support frame 10.

[0041] The diameter of the floating ball 40 is smaller than the inner diameter of the hollow tube 300, and the floating ball 40 is connected to one end of the rope body 200.

[0042] The suction end 52 and the floating ball 40 are respectively used to be connected to the two ends of the hollow tube 300. After the negative pressure device 50 is started, the suction end 52 sucks air, so as to suck the floating ball 40 into the hollow tube 300 and drive the rope body 200 to move. The floating ball 40 moves inside the hollow tube 300 until the floating ball 40 moves to the suction end 52.

[0043] ​​Generally speaking, the float ball 40 has a relatively small density. When the suction end 52 sucks in air, the float ball 40 can drive the rope body 200 to move within the hollow tube 300.

[0044] In this embodiment, the float ball 40 is a hollow ball. In other embodiments, the float ball 40 can also be a lightweight ball such as a foam ball.

[0045] When the rope threading device of the present invention is in use, the end of the hollow tube 300 is sleeved outside the connecting column 32, and the pulling device 30 moves along the track 20, so as to place the hollow tube 300 on the support frame 10. Connect the float ball 40 to one end of the rope body 200, and then connect the suction end 52 and the float ball 40 to the two ends of the hollow tube 300 respectively. After the negative pressure device 50 is started, the suction end 52 sucks in air, so as to suck the float ball 40 into the hollow tube 300 and drive the rope body 200 to move. The float ball 40 moves within the hollow tube 300 until the float ball 40 moves to the suction end 52, thus completing the rope threading.

[0046] When the rope threading device of the present invention is used for threading a hollow flexible hose, even if the hollow flexible hose is bent to block the rope threading due to its long length, it does not affect the movement of the float ball 40 within the hollow flexible hose, so that the rope threading of a relatively long hollow flexible hose can be realized.

[0047] Combined with Figure 2 , preferably, in this embodiment, a clamping device 34 that moves relative to the connecting column 32 is further provided at the lower end of the pulling device 30. When the end of the hollow tube 300 is sleeved outside the connecting column 32, the clamping device 34 moves relative to the connecting column 32 until the clamping device 34, the end of the hollow tube 300, and the connecting column 32 are in contact in sequence, so as to clamp the end of the hollow tube 300.

[0048] Combined with Figure 2 and Figure 3 , more preferably, in this embodiment, the clamping device 34 has an operating member 342 and a clamping member 344. The operating member 342 is used to control the clamping member 344 to approach or move away from the connecting column 32, and the clamping member 344 is used to contact the end of the hollow tube 300.

[0049] Combined with Figure 3 , in this embodiment, the clamping device 34 further includes a mounting seat 346 and a connecting rod 348.

[0050] Specifically, the operating member 342 has an opposite operating end 3421 and a first rotating end. The rotating end is provided with a first rotating portion 3422 and a second rotating portion 3424 spaced apart from each other. The clamping member 344 has an opposite clamping end 3441 and a second rotating end. The second rotating end is provided with a third rotating portion 3442 and a fourth rotating portion 3444 spaced apart from each other. The mounting seat 346 is provided with a fifth rotating portion 3462 and a sixth rotating portion 3464 spaced apart from each other.

[0051] The first rotating part 3422 is located diagonally above the second rotating part 3424, the third rotating part 3442 is located above the fourth rotating part 3444, and the fifth rotating part 3462 is higher than the sixth rotating part 3464.

[0052] One end of the second rotating part 3424 is rotatably connected to the connecting rod 348, the other end of the connecting rod 348 is rotatably connected to the sixth rotating part 3464, the first rotating part 3422 is rotatably connected to the third rotating part 3442, and the fourth rotating part 3444 is rotatably connected to the fifth rotating part 3462.

[0053] Through the above, the operating member 342 can better control the clamping member 344 to approach the connecting column 32, so that the clamping member 344 abuts against the end of the hollow tube 300.

[0054] Preferably, in combination with the attached drawings, in this embodiment, the retracting device 30 includes a main body 36 and a vertical rod 37.

The lower end of the vertical rod 37 passes through the middle of the two tracks 20 and is arranged above the support frame 10, and the connecting column 32 is arranged at the lower end of the vertical rod 37.

[0055] Preferably, in this embodiment, the vertical rod 37 can move up and down relative to the main body 36, thereby driving the connecting column 32 to move up and down relative to the main body 36, and thus can drive the connecting column 32 to move up and down relative to the support frame 10, so as to facilitate placing the hollow tube 300 on the support frame 10.

[0056] Preferably, in this embodiment, the retracting device 30 further includes a horizontal pulley 38 arranged at the lower end of the main body 36 and a vertical pulley 39 arranged on the side surface of the main body 36. The horizontal pulley 38 is connected to the side surface of the track 20, and the vertical pulley 39 is connected to the upper surface of the track 20.

[0057] More preferably, in this embodiment, there are two groups of horizontal pulleys 38, and the two groups of horizontal pulleys 38 are arranged at intervals. The track 20 is clamped between the two groups of horizontal pulleys 38, and a long strip-shaped groove 201 matching the horizontal pulley 38 is also arranged on the side surface of the track 20.

[0058] Such a structural setting enables the retracting device 30 to move more stably on the track 20.

[0059] Preferably, in combination with Figure 4 , in this embodiment, the threading device further includes a correcting device 60. The correcting device 60 is located in front of the support frame 10. A correcting through hole 601 matching the hollow tube 300 is arranged on the correcting device 60. The hollow tube 300 passes through the correcting through hole 601 and is placed on the support frame 10.

[0060] In combination with Figure 4, specifically, the correction device 60 includes a base 61, a mounting post 62 disposed on the base 61, a first clamping plate 63 sleeved on the mounting post 62, an elastic member 64 sleeved on the mounting post 62 and connecting the base 61 and the first clamping plate 63 respectively, a second clamping plate 65 sleeved on the mounting post 62 and located on the side of the first clamping plate 63 away from the base 61, and a baffle 66 fixedly connected to the mounting post 62 and located on the side of the second clamping plate 65 away from the base 61.

[0061] A correction through hole 601 is formed between the first clamping plate 63 and the second clamping plate 65. The first clamping plate 63 and the second clamping plate 65 are both slidably disposed on the mounting post 62. The elastic member 64 elastically abuts against the first clamping plate 63, so that when the hollow tube 300 passes through the correction through hole 601, the first clamping plate 63, the hollow tube 300, and the second clamping plate 65 abut against each other in sequence.

[0062] Preferably, in combination with the accompanying drawings, in this embodiment, the threading device further includes a winding device 70 for winding the hollow tube 300 through which the rope body 200 is threaded.

[0063] Combined with Figure 5 , the present invention also discloses a threading method for an embodiment, including the following steps:

[0064] S10. Provide the rope body 200, the hollow tube 300, and the above-mentioned threading device.

[0065] S20. Sleeve the end of the hollow tube 300 outside the connecting column 32, and the pulling device 30 moves along the track 20, so as to place the hollow tube 300 on the support frame 10.

[0066] Preferably, a clamping device 34 that moves relative to the connecting column 32 is further provided at the lower end of the pulling device 30.

[0067] S20 further includes, after the operation of sleeving the end of the hollow tube 300 outside the connecting column 32 and before the operation of the pulling device 30 moving along the track 20, performing the following operations: The clamping device 34 moves relative to the connecting column 32 until the clamping device 34, the end of the hollow tube 300, and the connecting column 32 abut against each other in sequence, so as to clamp the end of the hollow tube 300.

[0068] S30. Connect the floating ball 40 to one end of the rope body 200, and then connect the suction end 52 and the floating ball 40 to the two ends of the hollow tube 300 respectively;

[0070] When the rope threading method of the present invention is used for threading a rope through a hollow hose, even if the hollow hose is bent to block the rope threading due to the long length of the hollow hose, it does not affect the movement of the floating ball 40 inside the hollow hose, so that the rope threading of a relatively long hollow hose can be achieved.
