Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a wire threading machine for building construction. Background Technology

[0002] Steel wire is widely used in many fields such as building construction and electrical installation, with wire pulling and threading being key operational steps. Currently, the equipment used for wire pulling in existing construction processes is relatively simple, typically only capable of pulling the wire and unable to simultaneously complete the threading work. This forces construction workers to first use the wire pulling equipment to pull the wire and then use other methods to thread it, increasing the number of construction steps, extending the construction period, and reducing construction efficiency.

[0003] Meanwhile, under current technology, the fabrication and pulling of steel wires largely rely on manual labor. Manually fabricating steel wire requires skilled and experienced workers, and the process is tedious, labor-intensive, and prone to worker fatigue, thus affecting the quality and precision of the wire fabrication. Manually pulling wires is not only inefficient, but also suffers from uneven tension and wire damage when dealing with long distances or complex environments, making it difficult to guarantee construction quality and safety. Furthermore, manual operation also suffers from high labor costs and is greatly affected by human factors, failing to meet the requirements of modern construction for efficiency, precision, and safety.

[0060] The following is combined Figures 1-6 The embodiments shown illustrate the technical solution of this utility model:

[0061] A wire threading machine for construction includes: a housing 10, with a wire threading cavity inside the housing 10 and inlet / outlet holes extending through the horizontal axis of the wire threading cavity; two transmission components 20, rotatably disposed in the wire threading cavity with their transmission surfaces abutting each other; two drive components 30, rotatably disposed on the outside of the housing 10 corresponding to the two transmission components 20 and rotatably connected to them; a control component 40, disposed on the housing 10 and used to control the rotation of the two drive components 30; and a sealing cover 50, detachably disposed on the housing 10 and used to cover the wire threading cavity; wherein, a transmission cavity is formed between the two transmission components 20, through which the wire to be pulled passes and is moved by friction; and the control component 40 controls the torque of the two drive components 30 and controls the transmission speed of the two transmission components 20.

[0062] It is understandable that: the outer casing 10 has a draw wire cavity inside, and the outer casing 10 is a rectangular frame welded from scrap steel plates from a construction site. Two transmission components 20 are rotatably installed along the length of the draw wire cavity inside the outer casing 10. The two transmission components 20 are arranged in abutting position, so that the transmission surfaces of the two transmission components 20 are in close contact with each other, leaving a small gap between them. Furthermore, inlet and outlet holes are provided at both ends along the length of the outer casing 10, and the inlet and outlet holes are on the same horizontal plane as the contact surfaces of the two transmission components 20. This allows the steel wire to be more accurately... The two drive components 30 are inserted between the mating surfaces of the two transmission components 20 and are rotatably arranged on the outside of the housing 10 corresponding to the two transmission components 20. The two drive components 30 are connected to the two transmission components 20 respectively, so that each drive component 30 drives one transmission component 20. In order for the two rotating components to transmit in the same direction, the driving directions of the two drive components 30 are opposite. Next, the control component 40 is set on the outer side wall of the housing 10 and electrically connected to the two drive components 30. The control component 40 controls the torque change of the two drive components 30, thereby realizing the pulling and threading of the steel wire.

[0063] The steel wire threading machine for construction provided in this embodiment of the utility model uses two transmission components 20, which are fitted together in the outer casing 10. These two transmission components 20 are connected to two drive components 30, which in turn are connected to a control component 40. The steel wire is threaded through the inlet hole on the outer casing 10. The control component 40 activates the drive components 30, causing them to drive the two transmission components 20 to rotate. This allows the threaded steel wire to contact the contact surfaces of the two transmission components 20 and pass between them. The friction between the two transmission components 20 during their contact motion drives the wire through, achieving the threading effect. When encountering a bend during threading, the control component 40 readjusts the rotational torque of the drive components 30, increasing the transmission force between the two transmission components 20. This facilitates threading the wire through the bend, achieving integrated threading and pulling, thus reducing manpower and improving construction efficiency.

[0064] According to the embodiment of this utility model, the construction steel wire threading machine includes a housing 10 comprising: a storage box 11, the storage box 11 having a storage cavity inside and inlet / outlet holes at both ends along the length direction, the inlet / outlet holes being connected to the storage cavity; and two conveying pipes 12, the two conveying pipes 12 being disposed at both ends of the storage box 11 corresponding to the inlet / outlet holes and connected to the storage cavity.

[0065] Figure 1 and Figure 3A wire threading machine for construction is implemented. The outer shell 10 is formed by combining a storage box 11 and a conveying pipe 12. The storage box 11 is a rectangular frame welded from waste steel plates on the construction site. A storage cavity is opened inside the storage box 11, and inlet and outlet holes are opened at both ends along the length direction. The conveying pipe 12 is welded to the outside of the storage box 11 corresponding to the inlet and outlet holes. The conveying pipe 12 is a flexible structure that can be bent in any direction to guide the wire out of the outer shell 10, thereby making the position of the wire more accurate during pulling and threading, and avoiding deviation.

[0066] According to the embodiment of this utility model, the construction wire threading machine includes two transmission components 20: two active rollers 21, which are rotatably disposed at one end of the wire threading cavity along the length direction; two driven rollers 22, which are rotatably disposed at the other end of the wire threading cavity along the length direction; two conveyor belts 23, which are sleeved on the two active rollers 21 and the two driven rollers 22 and wrap the active rollers 21 and the driven rollers 22 on the same plane; and two sets of limiting rollers 24, which are disposed between the active rollers 21 and the driven rollers 22 and are rotatably connected to the wire threading cavity; wherein, each set of limiting rollers 24 has multiple sets, and the two conveyor belts 23 are respectively sleeved on the two active rollers 21 and the two driven rollers 22, so that the surfaces of the two conveyor belts 23 abut against each other and move synchronously.

[0067] Figure 3 and Figure 4A wire threading machine for construction is implemented. The transmission assembly 20 is formed by combining a drive roller 21, a driven roller 22, a conveyor belt 23, and a limiting roller 24. The drive roller 21 is rotatably mounted on one side inside the housing 10 and connected to the drive assembly 30, while the driven roller 22 is rotatably mounted on the other side inside the housing 10 and is on the same horizontal plane as the drive roller 21. The conveyor belt 23 covers the drive roller 21 and the driven roller 22, indirectly connecting them together. A distance is placed between the drive roller 21 and the driven roller 22, thus straightening the conveyor belt 23 to keep it horizontal. Furthermore, the drive roller 21 and the driven roller 22 are... Several limiting rollers 24 are set between the two conveyor belts 23. When the transmission belt is wrapped, the limiting rollers 24 also cover the conveyor belts 23. As the conveyor belts 23 rotate, the limiting rollers 24 prevent the conveyor belts 23 from sinking into the middle, so that the conveyor belts 23 can always maintain a horizontal state. When the conveying surfaces of the two conveyor belts 23 are in contact with each other, they can fit tightly with the surface of the steel wire, so as to pull and thread the steel wire. When the conveyor belts 23 are conveying, the two conveyor belts 23 move synchronously and the transmission direction is the same. When the driving roller 21, driven roller 22 and limiting roller 24 are installed with bearings on the rollers when they are installed with the housing 10, the rotation between the rollers is realized by the bearings.

[0068] According to the construction steel wire threading machine provided in this utility model embodiment, the surfaces of the two conveyor belts 23 are evenly provided with a plurality of protrusions 231 along the width direction and a conveying groove 232 is provided along the length direction. The inner wall of the conveying groove 232 is provided with the same spiral pattern as the surface of the steel wire being pulled. When the two conveyor belts 23 are placed together in the wire pulling cavity, the conveying groove 232 and the wire inlet and outlet holes are on the same horizontal axis.

[0069] Figure 3 and Figure 4 A wire threading and pulling machine for construction is implemented. Several adjustable ridges 231 are evenly arranged along the width direction on the surface of a conveyor belt 23. A conveying groove 232 is opened along the length direction at the middle position of the surface of the conveyor belt 23. The inner wall of the conveying groove 232 is provided with a spiral pattern identical to the surface of the wire being pulled. When two conveyor belts 23 are combined so that their conveying surfaces abut against each other, the conveying groove 232 on the conveyor belt 23 forms a wire conveying channel. This allows the wire to slide within the conveying groove 232 after being threaded through. The spiral pattern and ridges 231 increase the friction between the two conveyor belts 23 and the surface of the wire during relative conveying, thus better driving the wire to move within the conveying groove 232 on the conveyor belt 23, achieving the effects of threading and pulling the wire.

[0070] The wire threading machine for construction provided according to the present utility model embodiment further includes: multiple clamping components 60, each clamping component 60 including: multiple limiting rods 61, the multiple limiting rods 61 being disposed on multiple limiting rollers 24; multiple pull rods 62, the multiple pull rods 62 being sleeved on the multiple limiting rods 61; wherein, each pair of multiple limiting rods 61 is combined to form a group and each group of limiting rods 61 is pulled together by the pull rods 62.

[0071] Figure 3 and Figure 6 A wire threading machine for construction is implemented. The clamping assembly 60 is formed by the combination of a limiting rod 61 and a pull rod 62. The limiting rod 61 is a columnar structure that is rotatably embedded on one side of the limiting roller 24. The limiting roller 24 is used in conjunction with two transmission assemblies 20. The limiting roller 24, which is set on the two transmission assemblies 20, is fitted with the pull rod 62 on the limiting column. The pull rod 62 is a spring structure with hooks at both ends. The pull rod 62 is fitted on two limiting columns that are grouped together. By pulling the two limiting columns together, the pull rod 62 drives the limiting roller 24 on the two transmission assemblies 20 to move closer together. This makes the two conveyor belts 23 on the two transmission assemblies 20 more closely contacted, forming a clamping force to clamp the threaded wire. This increases the friction between the conveyor belts 23 and makes the wire pulling more stable.

[0072] According to the construction steel wire threading machine provided in this utility model embodiment, the two drive components 30 include: two drive motors 31, which are mounted on the outer shell 10. The drive ends of the two drive motors 31 rotate through the outer shell 10 and are connected to two active rollers 21. The two drive motors 31 drive the two active rollers 21 to rotate and drive the two conveyor belts 23 to abut against each other for transmission.

[0073] Figure 2 and Figure 4 A wire threading machine for building construction was implemented. The drive component 30 is a drive motor 31. The drive motor 31 is rotatably mounted on the outer casing 10 and the drive end is connected to the drive roller 21. The drive motor 31 drives the drive roller 21 to rotate, thereby driving the conveyor belt 23 for transmission. Two drive motors 31 are respectively connected to two drive rollers 21. In order to make the transmission direction of the two conveyor belts 23 the same, the rotation direction of the two drive motors 31 is exactly opposite, so that the driven conveyor belts 23 can maintain the same direction during rotation, and the two drive motors 31 rotate synchronously.

[0074] According to the embodiment of this utility model, the control component 40 of the building construction steel wire threading machine includes: a handle 41, which is disposed on the outer shell 10; a control switch 42, which is disposed on the handle 41; and a control module 43, which is disposed in the handle 41 and electrically connected to the control switch 42. The control module 43 is electrically connected to two drive components 30 and adjusts the current change on the control module 43 by opening and closing the control switch 42, thereby adjusting the rotational torque of the two drive components 30 and controlling the transmission speed of the two transmission components 20.

[0075] Figure 5 and Figure 6 A wire threading machine for building construction was implemented. The control component 40 is formed by combining a handle 41, a control switch 42, and a control module 43. The handle 41 is an arc-shaped structure fixedly installed on the side wall edge of the outer casing 10. The control switch 42 is installed on the handle 41, and the control module 43 is installed inside the handle 41. The control switch 42 and the control module 43 are electrically connected, and the control module 43 is also electrically connected to the drive motor 31. The control module 43 is an integrated circuit board with two circuits integrated in parallel. Each parallel circuit has two resistors with different resistance values. When the control switch 42 is turned on, one of the parallel circuits is connected, so that the resistor in the circuit is connected in series with the drive motor 31. The current is passed through the resistor into the drive motor 31, which then starts the drive motor 31 to rotate. When the input current to the drive motor 31 needs to be changed, the switch is pressed again, which connects the switch to another parallel circuit. The resistor in the other parallel circuit is connected in series with the drive motor 31. Since the resistance values ​​of each resistor are different, changing the resistance changes the input current to the drive motor 31, thereby changing the speed of the drive motor 31, that is, changing the rotational torque of the drive motor 31. The larger the resistance, the lower the voltage of the drive motor 31, the slower the speed and the greater the torque. The smaller the resistance, the higher the voltage of the drive motor 31, the faster the speed and the smaller the torque. This controls the transmission speed of the conveyor belt 23, so that the steel wire can be pulled and threaded.

[0076] According to the construction steel wire threading machine provided in this utility model embodiment, one end of the sealing cover 50 is provided with an inlay groove 51 corresponding to the multiple limiting rods 61 after being tightened. The inlay groove 51 is used to inlay and limit the multiple limiting rods 61 after being tightened.

[0077] Figure 4A wire threading machine for building construction is implemented. An inlay groove 51 is opened at one end of the sealing cover 50 corresponding to the multiple tensioned limiting rods 61. The inlay groove 51 inlays and fixes the tensioned multiple limiting rods 61. At the same time, the sealing cover 50 covers the outer shell 10 and seals the conveying cavity of the outer shell 10. The connection between the sealing cover 50 and the outer shell 10 is a threaded connection. In subsequent work, any problems can be directly opened to carry out maintenance and inspection, thus making maintenance more convenient.

[0078] Usage process:

[0079] In use, the two drive motors 31 are started by controlling the switch 42 on the handle 41, causing them to drive the two conveyor belts 23 to rotate. This causes the two conveyor belts 23 to move synchronously, allowing the steel wire to be inserted from the conveying pipe 12 on the outer casing 10 and simultaneously threaded between the two conveyor belts 23. The inserted steel wire is then threaded through the conveying groove 232 between the two conveyor belts 23, and the friction between the conveyor belts 23 drives the steel wire to move, thus pulling the wire and causing it to extend out from the other end of the conveying pipe 12. During the conveying process, when increased torque is required for wire threading, pressing the control switch 42 reduces the output current, decreases the voltage across the drive motor 31, and thus reduces the speed of the drive motor 31, thereby increasing the torque of the drive motor 31 and enabling wire threading. Since the conveying pipe 12 can change different angles, the wire can be pulled from different angles when extending or retracting, making wire pulling more convenient. This solves the problem that existing wire pulling methods can only pull but not thread, while also accelerating the construction progress and efficiency.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
