Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

First, the concept of "invalid probe rope" in the prior art needs to be explained:

when threading is carried out through the prior art, in order to avoid the situation that the line pipe cannot be penetrated due to the fact that the length of the exploring rope 100 is not enough, the length of the exploring rope 100 is generally larger than that of the line pipe. After the end of the probe strand 100 has been threaded from one end of the conduit to the other, the probe strand 100 remaining outside the conduit is referred to as an "invalid probe strand".

In actual operation, during the process that the detection rope 100 is led into a conduit or pulled out of the conduit, a worker needs to hold the detection rope by hand to avoid the detection rope from being entangled; at this time, the "invalid probe rope" causes the worker to consume excessive labor.

In addition, in the process of recovering the detection rope 100, a worker is required to pull the other end of the detection rope 100, so that the detection rope 100 is discontinuously bent while the detection rope 100 is pulled, and the detection rope 100 is sorted. However, due to the existence of the 'invalid detection rope', a worker is inconvenient to find the other end of the detection rope 100, and even if the other end of the detection rope 100 is found, the part of the 'invalid detection rope' needs to be bent firstly, so that redundant time waste is caused, the time for withdrawing the detection rope 100 is prolonged, and the working efficiency of threading operation is affected.

Referring to fig. 1 to 5, the threading apparatus of the present invention will be described. The threading apparatus comprises a thread storage shell 1 and a rotating shaft 2.

Specifically, the wire storage shell 1 is hollow inside, has an opening at one end, and has a first through hole 11 on the surface; the hollow part is used for storing the detection rope 100, the opening part is detachably connected with a sealing cover 12, the sealing cover 12 is used for sealing the opening part, and the first through hole 11 is used for enabling the detection rope 100 to stretch out and be connected in. The rotating shaft 2 penetrates through the sealing cover 12, the rotating shaft 2 can rotate by taking the axis of the rotating shaft 2 as an axis, the rotating shaft 2 is divided into two parts by the sealing cover 12, one part is a part inserted into the wire storage shell 1 and is mainly used for being bound with one end of the detection rope 100, and when the rotating shaft 2 rotates, the detection rope 100 is wound on the part of the rotating shaft 2, and the part is named as a winding part of the rotating shaft 2. The second part is a part positioned outside the wire storage shell, the main function of the second part is that the second part is used for a worker to grab and shake, so that the effect of driving the winding part to rotate is achieved, and the second part is named as a driving part.

Utilize the utility model provides a during threading is carried out to the threading apparatus, at first, the workman stimulates the rope 100 tip of visiting that stretches out by first through-hole 11 and stretches into the spool with it, and along with constantly spuring visit rope 100 and will visit rope 100 and deliver to the spool is interior, reach the purpose that lets in the rope with visiting rope 100 in the storage shell 1. After spy rope 100 is worn to move to the other end of spool by the one end of spool, will visit the tip and the connection of electric lines of rope 100, later the drive division of manual rotation pivot 2, along with pivot 2 rotates, spy rope 100 withdraws in the storage line shell 1 and twines on the winding of pivot 2 along first through-hole 11, simultaneously with spy rope 100's end connection's electric line by spy rope 100 pulling to the spool in. When the end part of the detection rope 100 connected with the electric wire is pulled out of the conduit, the detection rope 100 is separated from the electric wire, the electric wire is completely connected into the conduit, the detection rope 100 is contained in the wire storage shell 1 and wound on the rotating shaft 2, the detection rope 100 in the wire storage shell 1 can be taken out by opening the sealing cover 12, or the wire storage shell is directly placed on one side; compared with the storage mode in the prior art, the storage mode is more reasonable, when the storage mode is reused, because one end of the exploring rope 100 is fixed on the winding part of the rotating shaft 2, and the other end extends out along the first through hole 11, workers do not need to find the two ends of the exploring rope 100, and the threading operation efficiency is improved; in addition, in the above process, workers do not need to lift the detection rope 100 or the wire storage shell 1, so that the labor consumption of the workers is effectively saved.

The utility model provides a threading apparatus compares with prior art, and at threading operation in-process, the tip of visiting rope 100 is stretched out by first through-hole 11, and the workman of being convenient for seeks. Through the drive division that rotates pivot 2, make and visit rope 100 by the spool in receive back store up in the line shell 1 and twine with pivot 2 on, its process is convenient for operate, and need not the workman and lift and visit rope 100 or store up line shell 1, has effectively practiced thrift manpower output to the process of withdrawing and visiting rope 100 is gone on with the process of arranging and visiting rope 100 in step, has effectively improved the efficiency of electric wire threading operation.

In the process of withdrawing the detection rope 100 into the wire storage shell 1, the end part of the detection rope 100 connected with the rotating shaft 2 continuously rotates along with the rotation of the rotating shaft 2; if the connection between the detection rope 100 and the rotating shaft 2 is unstable, the phenomenon that the detection rope 100 slips on the outer wall of the rotating shaft 2 can occur, and the efficiency of the wire threading operation is affected. In order to avoid the occurrence of the slipping phenomenon, please refer to fig. 2, as a specific embodiment of the threading apparatus provided by the present invention, a fixing ring 21 for detecting the threading apparatus 100 is disposed on the rotating shaft 2, the fixing ring 21 is fixedly welded to the rotating shaft 2, and the fixing ring 21 is disposed with two rings and arranged along the circumferential direction of the rotating shaft, in the process of connecting the detecting rope 100 to the rotating shaft 2, the end of the detecting rope 100 firstly sequentially passes through the ring holes of the two fixing rings 21, and then extends out of the thread storage case 1 along the first through hole 11. When the rotating shaft 2 rotates, the fixing ring 21 deflects in the same direction, so that the end part of the detection rope 100 is driven to rotate, and the main body of the detection rope 100 is wound on the rotating shaft 2.

When the detection rope 100 is wound along the outer wall of the rotating shaft 2, as the winding amount of the detection rope 100 is more and more, the detection rope 100 is wound from one end of the winding part of the rotating shaft 2 to the other end; at this time, if there is a gap between the end surface of the rotating shaft 2 extending into the wire storage case 1 and the inner wall of the wire storage case 1, or a gap is generated between the end surface of the rotating shaft 2 extending into the wire storage case 1 and the inner wall of the wire storage case 1 due to the sliding of the rotating shaft 2, the detection rope 100 is separated from the rotating shaft 2 by the gap, but since the end portion of the detection rope 100 is still fixedly connected to the rotating shaft 2, when the rotating shaft 2 rotates, the detection rope 100 still rotates along with the rotation of the rotating shaft 2, but when the detection rope 100 is taken out, the detection rope 100 continuously extends out from the first through hole 11, which may possibly cause a blocking phenomenon. Therefore, in order to avoid the above situation, please refer to fig. 2 and fig. 5 together, as a specific embodiment of the threading apparatus provided by the present invention, after the sealing cover 12 is connected with the thread storage case 1, the end surface of the rotating shaft 2 abuts against the inner wall of the thread storage case 1; and two baffles 22 are fixedly arranged on the rotating shaft 2, and the two baffles 22 are respectively used for abutting against the outer surface and the inner surface of the sealing cover 12. After the end part of the detection rope 100 is connected with the winding part of the rotating shaft 2 and the sealing cover 12 is installed on the wire storage shell 1, the detection rope 100 is wound on the shaft body of the rotating shaft 2 along with the rotation of the rotating shaft 2, and the situation that the detection rope 100 is separated from the rotating shaft 2 is avoided because the end surface of the rotating shaft 2 is abutted against the inner wall of the wire storage shell 1; moreover, the two baffles 22 fixed on the rotating shaft 2 abut against two side surfaces of the cover 12, and when the rotating shaft 2 tends to slide along its own axial direction, one of the baffles 22 will generate an interaction force with the cover 12, so as to counteract the above-mentioned tendency, and achieve the purpose of limiting the rotating shaft 2 from sliding along its own axial direction.

In order to make the threading apparatus of the present invention more convenient for manual use, please refer to fig. 1 to 4 together, as a specific embodiment of the threading apparatus of the present invention, a first grip 13 is disposed on the thread storage case 1, and a second grip 13 is disposed on the driving portion of the rotating shaft 2. Specifically, the first grip 13 is used for being held by a worker, the second grip 13 is used for being held and rotated by the worker, and when the first grip 13 is held by the hand, the arrangement angle of the cord storage case 1 can be selected according to the use habit of the worker. When the threading operation is carried out by taking a line pipe on the ground as an access position, the threading device is placed on the ground, and the fixing of the device can be realized by holding the first grip 13 by hands.

When the threading apparatus provided by the utility model is actually operated, a worker finds that the detection rope 100 is withdrawn by rotating the rotating shaft 2, so that the threading operation efficiency can be effectively improved in the process of inserting the electric wire into the wire tube, but the connection and separation of the detection rope 100 and the electric wire can be easily caused, and the situation can be avoided; referring to fig. 1 to 3, as a specific embodiment of the threader of the present invention, the threader further includes a fixing member 3, one end of the fixing member 3 is used for being fixedly connected to an end of the detecting rope 100, and the other end of the fixing member 3 is used for being fixedly connected to an end of an electric wire; the fixing piece 3 is arranged, so that the direct contact connection between the detection rope 100 and the electric wire is avoided, and the separation of the detection rope 100 and the electric wire in threading operation caused by insufficient connection strength of the detection rope 100 and the electric wire is avoided; therefore, the fixing member 3 can improve the connection strength between the electric wire and the probe line 100, and the sectional area of the fixing member 3 should be smaller than or equal to that of the probe line 100 in order to prevent the probe line 100 loaded with the fixing member 3 from being inserted into the conduit.

Referring to fig. 3, as a specific embodiment of the threading apparatus provided by the present invention, the fixing member 3 includes a base 31, a connecting member 32 having one end fixed on the base 31, and a limiting plate 33 rotatably disposed on the connecting member 32. The base 31 is used to connect with the end of the probe line 100, and generally, the base 31 and the probe line 100 are welded to enhance the connection. The other end of the connecting piece 32 is provided with a limiting groove 321 for inserting the wire, and the limiting groove 321 is provided with anti-slip threads for increasing friction force, and the sectional area of the opening of the limiting groove 321 is equal to or slightly smaller than the sectional area of the wire (since the outer skin of the wire is generally made of elastic material, when the wire is plugged into the limiting groove 321, the situation that the wire cannot be plugged in because the limiting groove 321 is slightly smaller than the sectional area of the wire does not occur). The stopper plate is adapted to rotate after the electric wire is inserted into the stopper groove 321 and abut against the outer surface of the electric wire, and has a connecting tooth 331 at an end thereof for inserting the outer skin of the electric wire after the stopper plate 33 abuts against the outer surface of the electric wire.

Through adopting above-mentioned technical scheme, the workman is when being connected the electric wire with spy rope 100, at first fills in the spacing groove 321 to the electric wire in, later overturns limiting plate 33 180 degrees, makes limiting plate 33's connecting teeth 331 insert the plastic crust of electric wire to make the joint strength who strengthens electric wire and mounting, and then strengthen the stability of electric wire and spy rope 100's relation of connection.

In order to further strengthen the connection relationship between the electric wire and the detecting rope 100, please refer to fig. 3, as a specific embodiment of the threading apparatus provided by the present invention, the plurality of limiting plates 33 are provided, and the plurality of limiting plates 33 are arranged along the circumferential direction of the connecting member 32. In the present embodiment, four stopper plates 33 are provided, and the four stopper plates 33 are arranged along the circumferential direction of the connecting member 32. The periphery of the electric wire is locked by the four limiting plates 33, so that the connection between the electric wire and the detection rope 100 is more stable.

Because the space in the spool is limited, if the limiting plate 33 rotates and sets up in the surface of connecting piece 32, when spy rope 100 not with electric wire connection, mounting 3 along with spy rope 100 moves in the spool, the connection tooth 331 of limiting plate 33 very easily can contact with the spool inner wall to cause the spool inner wall to draw the damage, even the destroyed condition of connection tooth 331. In order to avoid the above situation, please refer to fig. 3, as a specific implementation of the threading apparatus provided by the present invention, a groove 322 is provided on the connecting member 32, and the limiting plate 33 is rotatably disposed in the groove 322. When the detection rope 100 passes through the conduit, the limiting plate 33 rotates into the groove 322, and a space is formed between the connecting teeth 331 and the inner wall of the conduit, and the limiting plate 33 cannot be turned over at the space. And, can set up limiting plate 33 into elastic material, set up the open area of recess 322 into slightly being lighter than limiting plate 33 cross sectional area, when limiting plate 33 rotated to recess 322 department, limiting plate 33 took place elastic deformation and joint in recess 322, made limiting plate 33 and recess 322 be connected more stably.

By adopting the technical scheme, before the exploring rope 100 is connected into the line pipe, a worker shifts the limiting plate 33, so that the limiting plate 33 is collected into the groove 322; after the detection rope 100 is connected into the conduit, the limiting plate 33 is positioned in the groove 322, and a space is formed between the connecting teeth 331 and the inner wall of the conduit, so that the direct contact between the connecting teeth 331 and the inner wall of the conduit is avoided, and the condition that the connecting teeth 331 are damaged or the conduit is damaged due to the friction between the connecting teeth 331 and the inner wall of the conduit is avoided; after the detection rope 100 passes through one end of the conduit and extends out of the other end of the conduit, a worker inserts the electric wire into the limiting groove 321, then manually turns over the limiting plate 33, so that the limiting plate 33 rotates for 90 degrees and the connecting teeth 331 are inserted into the outer skin of the electric wire, and in the process of withdrawing the detection rope 100, because the connecting teeth 331 are positioned in the outer skin of the electric wire, friction between the connecting teeth 331 and the inner wall of the conduit is also avoided. In summary, through setting up recess 322, make the limiting plate 33 rotate and set up in recess 322, and when the limiting plate 33 was located recess 322, have the interval between engaging tooth 331 and the spool inner wall, can avoid rotating the state of laminating with connecting piece 32 at limiting plate 33, the condition that engaging tooth 331 and spool inner wall take place the friction damage.

When the opening of the spool is located on the ground, if the process of putting the spool case 1 on the ground to retrieve the detection rope 100 is performed, the detection rope 100 extends out of the opening of the spool and is retrieved from the first through hole 11 to the spool case 1, and the opening direction (horizontal direction) of the first through hole 11 is perpendicular to the opening direction (vertical direction) of the spool, so that the operation is very inconvenient. In order to solve the above problem, please refer to fig. 1, fig. 4 and fig. 5 together, as a specific embodiment of the threading apparatus provided by the present invention, an abutting member 4 for abutting against the wall where the thread tube is located is disposed on the outer wall of the thread storage case 1, and a second through hole 41 for the penetration of the detecting rope 100 is disposed on the abutting member 4; and the joint of the abutting piece 4 and the wire storage shell 1 is positioned at the first through hole 11, and the first through hole 11 is connected with the second through hole 41. Specifically, the abutting part 4 is divided into two parts, one part is a connecting part which is funnel-shaped and is used for abutting against the ground where the spool is located, and an extending part with one end fixed on the connecting part and the other end fixed on the wire storage shell 1 and used for extending the height from the wire storage shell 1 to the wall where the spool is located. When the detection rope 100 is withdrawn from a line pipe on the ground, the rotating shaft 2 is rotated in the reverse direction (the reverse direction refers to the direction opposite to the direction of the rotating shaft 2 when the detection rope 100 is withdrawn), so that the detection rope 100 can be extended out and led into the line pipe; in this case, the higher the length of the extension portion is, the higher the plane of the driving portion of the rotating shaft 2 is, and the height of the extension portion is appropriately selected, so that a worker can avoid bowing or crouching down, and the burden on the body of the worker due to long-time work can be effectively alleviated.
