A threading device

Abstract

A wire threading device includes a base plate, a steel wire, a device box, and a pusher box. The device box has a first drive box, and inside the device box are a reciprocating threaded rod, a sliding rod, a take-up drum, and a pressing assembly. The pusher box has a second drive box and a driven wheel. The reciprocating threaded rod has a threaded sleeve assembly, and the sliding rod has a sliding sleeve assembly. The end of the steel wire is equipped with a sliding deflector. During the wire winding and unwinding process, the pusher box controls the forward and reverse rotation of the motors in the first and second drive boxes, thereby completing the winding and unwinding operation. When encountering a bend, the sliding deflector rotates to generate a deflection force, adjusting the end's orientation towards the conduit. The threaded sleeve assembly moves cyclically along the direction of the reciprocating threaded rod, causing the steel wire to wind orderly onto the surface of the take-up drum. The pressing assembly compresses the coiled steel wire to prevent it from unraveling. This design not only enables rapid wire threading without requiring repeated operations, but also facilitates convenient steel wire retrieval.

Description

Technical Field

[0001] This invention relates to an engineering threading device, belonging to the field of engineering threading technology, and particularly to a threading apparatus. Background Technology

[0002] Building electrical wiring typically involves pre-installing steel wire inside conduits after they have been laid. The steel wire is inserted into the conduit from one end and pushed along the conduit until it exits from the other end. The exiting end of the steel wire is then securely connected to the cable. Finally, the steel wire is pulled back from its original insertion point, allowing the cable to be pulled into the conduit. However, current wiring methods still present the following problems:

[0003] 1. One end of the steel wire is flat, which makes it easy to get stuck at the bend inside the pipe, preventing it from passing through quickly. It is necessary to constantly pull and push the steel wire to adjust the angle, making the threading process too cumbersome and the threading efficiency low.

[0004] 2. During the steel wire recycling process, due to the excessive length of the steel wire, it will become disorderly entangled, making it inconvenient to rewind and resulting in low recycling efficiency.

[0069] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0070] 1. The present invention provides a threading device comprising a base plate, a device box, a wire pusher box, a steel wire, and casters. A first motor is mounted on the top of the device box, and a second motor is mounted on the wire pusher box. The device box contains a reciprocating threaded rod, a sliding rod, and a transmission rod. A take-up drum is mounted on the transmission rod. A threaded rod assembly is fitted onto the reciprocating threaded rod, and a sliding sleeve assembly is fitted onto the sliding rod. A sliding steering device is provided at the end of the steel wire. In use, the device box is pushed to the pipe opening, the end of the steel wire is placed into the pipe, and the second motor is started. The steel wire is released from the take-up drum, passes through the threaded rod assembly, and the sliding sleeve... The component and push-wire box adjust the angle of the wire entering the pipe. Then, the first motor is started to feed the steel wire into the pipe. Because the end of the steel wire is equipped with a sliding deflector, it slides when encountering a bend, changing the direction of the end and allowing it to pass smoothly through the pipe bend. If it encounters a bend that cannot be passed through automatically, the first and second motors are started in reverse to retract part of the steel wire and adjust the angle. Then, the motors are turned forward again to allow the steel wire to pass through. Workers do not need to repeatedly pull and pull the steel wire to adjust the angle, saving time and effort. Therefore, this invention not only ensures smooth steel wire passage through pipes but also eliminates the need for repeated operations, simplifying the wire threading process and increasing efficiency.

[0071] 2. The present invention provides a threading device comprising a base plate, a device box, a pusher box, a steel wire, and casters. A first drive box is located on the top of the device box, and a second motor is mounted on the pusher box. The device box contains a reciprocating threaded rod, a sliding rod, and a transmission rod. A take-up drum is mounted on the transmission rod, and a pressing component is located beside the take-up drum. A threaded rod assembly is fitted onto the reciprocating threaded rod, and the threaded assembly moves along the direction of the reciprocating threaded rod. A sliding sleeve assembly is fitted onto the sliding rod. The reciprocating threaded rod and the transmission rod are synchronously driven by a transmission component. A sliding steering device is located at the end of the steel wire. In application, when the steel wire needs to be retrieved, the first and second motors are started in reverse. During retrieval, the steel wire's direction is restricted by the sliding sleeve assembly and the threaded rod assembly. The reciprocating threaded rod and the transmission rod are synchronously driven, and the threaded rod assembly moves along the direction of the reciprocating threaded rod, thereby driving the steel wire to wind orderly along the take-up drum. The pressing component presses against the surface of the wound steel wire coil to make it tightly wound for easy reuse. During this process, the orderly winding of the steel wire is automatic, requiring no manual operation. Therefore, this invention not only makes steel wire recycling more convenient, but also has a higher recycling efficiency.

[0072] 3. In the threading device of the present invention, the pusher box is a rectangular hollow box, inside which are arranged a first driven wheel and a second driven wheel. The outer circumference of the first and second driven wheels is recessed towards the axis to form a semi-circular groove. The semi-circular grooves together form a first circular groove. The steel wire passes through the first circular groove. A second drive box is provided on the back of the pusher box, and handles are provided on both sides of the drive box. Buttons are provided on the handles. In application, the buttons on the pusher box can control the first motor and the second motor, thereby controlling the threading and retraction of the steel wire. The steel wire passing through the first circular groove ensures that the steel wire will not deviate or move arbitrarily. Therefore, the present invention is not only convenient for threading and retraction, but also relatively easy to operate.

[0073] 4. In the threading device of the present invention, an upper liquid storage tank is installed on the left vertical plate, and a scraper is provided in the middle of the left vertical plate. The interior of the liquid storage tank forms a liquid storage cavity. A dripper is provided on the right side of the bottom surface of the liquid storage tank inside the first cavity, and the dripper is connected to the liquid storage cavity. A liquid collection tank is fixedly connected to the right side wall of the lower part of the left vertical plate. The liquid collection tank is a hollow box with an open top surface, and the top opening of the liquid collection tank is correspondingly set with the dripper. The steel wire is located between the dripper and the liquid collection tank. In application, the grease inside the liquid storage tank drips onto the steel wire under the action of gravity, so that the surface of the steel wire is covered with grease, making the steel wire smoother during the threading process. Excess grease is scraped off by the scraper and collected in the liquid collection tank for reuse. Therefore, the present invention not only makes the steel wire threading smooth, but also has high threading efficiency. Attached Figure Description

These sliding sleeve assemblies 18 are connected by a fixed connecting plate 9. Each sliding sleeve assembly 18 has a fifth driven wheel 182 and a sixth driven wheel 183, which together form a third arc groove 187. During operation, the first arc groove 243 generates friction on the steel wire 8 through the forward and reverse rotation of the motor, thereby performing the winding and unwinding of the wire. During the pushing and rewinding process, the steel wire 8 is restricted by the shapes of the second arc groove 194 and the third arc groove 187, preventing it from deviating from the predetermined path. When the transmission rod 6 and the reciprocating threaded rod 12 rotate synchronously, the sliding sleeve assembly 18 moves in a regular and orderly manner along the direction of the reciprocating threaded rod 12, causing the steel wire to be wound in an orderly manner on the surface of the take-up drum for the next use.

[0150] During application, the threading operation begins. The device box 2 is pushed to the pipe opening using the casters 35. The sliding steering device 37 is then placed inside the pipe opening. The operator holds the pusher box 3, and the button on the pusher box 3 controls the start of the first motor 5. The first motor 5 drives the transmission rod 6 to rotate, which in turn drives the take-up drum 7 on the transmission rod 6 to rotate and release the steel wire 8. At this time, the first transmission wheel 13 at the top of the transmission rod 6 drives the second transmission wheel 131 to rotate through the transmission component 14, simultaneously driving the reciprocating threaded rod 12 to rotate synchronously. While the reciprocating threaded rod 12 rotates, the threaded sleeve on the reciprocating threaded rod 12... The assembly 15 moves reciprocally along the thread on the outer wall of the reciprocating threaded rod 12, while the slider 11 moves along the direction of the slide groove 361 to ensure the stability of the threaded sleeve assembly 15. The steel wire 8 is released orderly from the take-up drum 7. When the steel wire 8 passes through the slide sleeve assembly 18 on the slide rod 17, it is restricted by the third arc groove 187 provided on the slide sleeve assembly 18. Since the slide sleeve assembly 18 is fixed in the middle of the slide rod 17, the steel wire 8 can only move horizontally, ensuring the stability of the movement path of the steel wire 8. When the steel wire 8 passes through the liquid storage tank 32, the grease inside the liquid storage tank 32 is... Under the action of force, the dripper 33 drips onto the surface of the steel wire 8, covering the surface of the steel wire 8 with a layer of lubricating grease. Excess lubricating grease is scraped off by the scraper 20 and falls into the collection tank 34 below, avoiding waste. After the steel wire 8 runs to the outside of the device box 2, it enters the inside of the pusher box 3. The steel wire 8 passes through the first threading tube 31, the first arc groove 243, the second threading tube 311, and the docking tube 30 in sequence. The button on the pusher box 3 controls the second motor 22 to start. Driven by the rotational friction between the first driven wheel 24 and the second driven wheel 241, the steel wire 8 moves towards... Inside the pipe, when the steel wire 8 reaches a bend, the rotating column 28 and rotating ball 29 at the end of the steel wire 8 will rotate on their own, generating a deflection force and changing the orientation of the end. With the combined action of the lubricant, rotating column 28, and rotating ball 29, it can pass through the bend. If it encounters a place that cannot be passed by the rotation of the rotating column 28 and rotating ball 29, the second motor 22 is started to reverse, retracting part of the steel wire 8. The positions of the device box and the pusher box 3 can be adjusted to change the position of the steel wire 8. The second motor 22 is started again to rotate forward, thus passing through the difficult bend and completing the threading operation.

The pressing component 10 includes a pressing cylinder 101, a first connecting rod 102, a first crossbar 103, a second crossbar 104, a spring 105, a crossbar sleeve 106, and a connecting sleeve 107.

[0154] During application, the recycling operation begins, and the first motor 5 and the second motor 22 are started in reverse. The steel wire 8 passes sequentially through the second threading drum 311, the first arc groove 243, the first threading drum 31, the scraper drum 20, the third arc groove 187, and the second arc groove 194. As the steel wire 8 moves, its movement is restricted by the second threading drum 311, the first arc groove 243, the first threading drum 31, the scraper drum 20, the third arc groove 187, and the second arc groove 194, allowing it to move only in the horizontal direction. When the steel wire 8 moves to the reciprocating threaded rod 12, the threaded sleeve assembly 15 on the reciprocating threaded rod 12 moves along the thread toward one end of the reciprocating threaded rod 12, thereby causing the steel wire 8 to wind around one end of the take-up drum 7. Then the threaded sleeve assembly 15 moves toward the other end of the reciprocating threaded rod 12, causing the steel wire 8 to wind around the other end of the take-up drum 7. The first baffle 71 and the second baffle 72 on both sides of the take-up drum 7 will restrict the steel wire 8 to always be wound on the take-up drum 7, so that the steel wire is wound in an orderly manner for easy use next time.

[0155] Example 3:

[0156] The basic content is the same as in Example 2, except that:

[0157] One end of the first crossbar 103 is fixedly connected to the left side wall of the lower part of the right vertical plate 204, and one end of the second crossbar 104 is fixedly connected to the left side wall of the right vertical plate 204 below the first crossbar 103; the other ends of the first crossbar 103 and the second crossbar 104 extend toward the reciprocating threaded rod 12; a crossbar sleeve 106 is fixedly connected to one end of the first crossbar 103 and the second crossbar 104 near the reciprocating threaded rod 12, and a spring 105 is sleeved on both the first crossbar 103 and the second crossbar 104, the spring 105 being disposed between the crossbar sleeve 106 and the right vertical plate 204; the diameter of the crossbar sleeve 106 is larger than that of the first crossbar 103 and the second crossbar 104. 4. The diameter of the spring 105 is smaller than that of the crossbar sleeve 106; the front end of the crossbar sleeve 106 is fixedly connected to a connecting sleeve 107, and a first connecting rod 102 is movably connected between the connecting sleeves 107. A pressure cylinder 101 is fixedly connected to the first connecting rod 102, and the first connecting rod 102 is rotatably connected to the connecting sleeve 107; a first baffle 71 is provided at one end of the take-up drum 7, and a second baffle 72 is provided at the other end of the take-up drum 7; the steel wire 8 is wound on the take-up drum 7 in the area between the first baffle 71 and the second baffle 72; the pressure cylinder 101 presses against the surface of the steel wire coil formed by the steel wire 8 wound between the first baffle 71 and the second baffle 72.

[0158] In application, the pressure cylinder 101 presses against the surface of the steel wire coil formed by the steel wire 8. Due to the compression and rebound of the spring 105, the diameter of the steel wire coil will increase or decrease during the unwinding and rewinding of the steel wire 8. The spring 105 always presses the pressure cylinder 101 against the surface of the steel wire coil, so that the winding of the steel wire coil always remains tight and will not become tangled.

[0159] Example 4:

[0160] The basic content is the same as in Example 3, except that:

[0161] The sliding steering device 37 includes a rotating column 28 and a rotating ball 29; the rotating column 28 is movably connected to a bearing component 281, the bearing component 281 is fixedly connected to the end of the steel wire 8, and the rotating column 28 rotates along the axis of the bearing component 281; the rotating ball 29 is movably connected to a bracket 291, the bracket is fixedly connected to the end of the steel wire 8, and the rotating ball 29 consists of two symmetrically arranged hemispheres, and the rotating ball 29 rotates around the center of the hemisphere cross-section.

[0162] In application, the rotating column 28 rotates along the axis of the bearing component 281, and the rotating ball 29 rotates along the center of the hemispherical section. The rotation directions of the two components overlap, so that when the end of the steel wire 8 touches the pipe in any direction, it can generate a deflection force, change its orientation, and thus pass through the pipe smoothly.

[0163] Example 5:

[0164] The basic content is the same as in Example 1, except that:

[0165] A first fixing ring 312 is fixedly connected to the middle of the left side wall and the middle of the right side wall of the first right upright plate 304.

The second threading tube 311 passes through the second fixing ring 313, and a portion of the second threading tube 311 extends into the push-wire cavity 307. One end of a third crossbar 308 and a fourth crossbar 309 is fixedly connected to the left side wall of the first left upright plate 303. The free ends of the third crossbar 308 and the fourth crossbar 309 extend toward the sliding steering device 37. A fourth crossbar 309 is provided below the third crossbar 308. A second connecting rod 310 is connected between the free end of the third crossbar 308 and the free end of the fourth crossbar 309. The docking tube 30 is sleeved on the second connecting rod 310.

[0166] During application, the direction of movement of the end of the steel wire 8 is unpredictable. During this process, the steel wire 8 will cause wear on the push box 3. The docking cylinder 30 set on the outer wall of the push box 3 will swing with the steel wire 8, thereby protecting the push box 3 and avoiding wear.
