Description

Technical Field

[0001] The utility model relates to the field of traction devices, in particular to a traction device for preparing steel wire pipes. Background Technique

[0002] A steel wire pipe is an industrial product of the pipe type. It has a variety of structures and wide application fields. Its raw material is extruded by an extruder and enters a sizing guide pipe installed with a first-stage negative pressure cooling box for cooling and shaping into the inner core of a PE composite pipe. Then it is pulled by a first traction box to a wire winding machine. After cutting off the outer sizing guide pipe, a wire mesh is wound around the outer side of the PE composite pipe inner core. After passing through a glue extruder and an extruder, it enters a guide pipe installed with a second-stage negative pressure cooling box for cooling and shaping, and then is pulled out by a second traction box. After cutting off the outer guide pipe, it goes to the next process.

[0003] In the existing production line, the guide pipe installed in the second stage is relatively heavy. When installing it, manual cooperation with semi-automatic machinery is required for filling, which is time-consuming and laborious. If there is a deviation during the installation of the guide pipe, it may cause deviations or twists in the steel wire or steel strip during the forming process, thus affecting the shape, size and performance of the steel wire pipe. Moreover, the sealing ring of the negative pressure cooling box is easily scratched by the outer wall of the guide pipe, affecting the smoothness of the outer wall of the steel wire pipe.

[0004] Therefore, aiming at the problem that the existing second-stage guide pipe is relatively heavy and its outer wall may scratch the sealing ring of the negative pressure cooling box during installation, affecting the smoothness of the outer wall of the steel wire pipe, a traction device for preparing steel wire pipes can be designed. A traction bracket drives a plurality of pulleys for combination, and a steel cable directly pulls the steel wire pipe to the second traction box, eliminating various drawbacks brought by installing the guide pipe. Content of the Utility Model

[0005] In order to overcome the problem that the existing second-stage guide pipe is relatively heavy and its outer wall may scratch the sealing ring of the negative pressure cooling box during installation.

[0006] The technical solution of the utility model is as follows: A traction device for preparing steel wire pipes includes a load-bearing base, a winch, a winding and unwinding machine, a U-shaped support plate and a steel cable; the winch and the winding and unwinding machine are linearly installed above the load-bearing base. A U-shaped support plate is installed on one side of the load-bearing base away from the winch. The steel cable passes through the winch, the winding and unwinding machine and the U-shaped support plate. A U-shaped frame is installed at one end of the U-shaped support plate away from the load-bearing base. A first pulley is installed in the middle of the U-shaped frame. An L-shaped support plate is installed at the lower end of the U-shaped support plate. Four groups of first fixed ring sleeves fixedly connected to the U-shaped support plate are horizontally installed on one side of the upper end of the L-shaped support plate. A traction bracket is arranged below the first fixed ring sleeve. A second support rod is horizontally installed at the bottom of the traction bracket. Two groups of vertical plates are horizontally installed in the middle of the side of the second support rod away from the I-shaped frame. A fourth pulley is installed between the two groups of vertical plates.

[0007] Preferably, the steel cable is passed through the winding and unwinding machine along the traction bracket and the U-shaped support plate, and is tightened or released by the winch. This method can avoid the situation that the outer wall of the guiding pipe scratches the sealing ring of the negative pressure cooling box during the installation of the guiding pipe. In this process, if the guiding pipe is used for transmission, production line failures may occur due to problems such as wear, blockage, or fracture of the guiding pipe, and the guiding pipe needs to be installed manually, which is time-consuming and laborious. However, using the traction bracket directly mechanically traction the steel wire pipe, reducing potential failure points in this link and improving the stability and reliability of the production line.

[0008] As a preference, a placement table fixedly connected to the load-bearing base is provided on one side of the winch. A speed reducer is installed at the upper end of the placement table. A motor fixedly connected to the placement table is provided on one side of the speed reducer. Two groups of rectangular mounting sleeves are horizontally installed on the side of the base where the U-shaped support plate is installed. An installation column passes through the middle of the rectangular mounting sleeve, and a nut is sleeved outside the installation column. Driven by the motor, the winch tightens or releases the steel cable. In this process, through the function of the speed reducer, the speed of the steel cable winding and unwinding is balanced, improving the practicability and flexibility when the steel cable is wound.

[0009] As a preference, a support frame is installed at the upper end of the winding and unwinding machine. Two groups of limiters are horizontally installed on one side of the support frame. A limit block is provided inside the winding and unwinding machine. A round hole is opened in the middle of the limit block. A limit rod passes through the middle of the round hole opened in the limit block. During the winding process of the steel cable, when the steel cable is tightened or released to a certain angle, the limit rod touches the limiter, and the limit block will stop to prevent over-tightening or over-releasing, resulting in changes in the angle of the steel wire pipe and being unable to be smoothly towed to the second traction box, improving the safety of the traction device.

[0010] As a preference, a first support rod is installed in the middle of both ends of the U-shaped support plate. A rectangular fixing block fixedly connected to the U-shaped support plate is provided on one side of the U-shaped frame. The first support rod provides a stable support for the U-shaped support plate, avoiding skewing during the process of towing the steel cable and avoiding affecting the shape, size, and performance of the steel cable.

[0011] As a preference, a rectangular cover plate is provided above the rectangular fixing block. Two groups of second pulleys are horizontally installed between the rectangular cover plate and the rectangular fixing block. A U-shaped groove is opened at the edge of the side of the U-shaped support plate away from the load-bearing base. A third pulley is installed in the middle of the U-shaped groove opened in the U-shaped support plate. The steel cable first passes through the fourth pulley between the two vertical plates, then through the third pulley, then through the first pulley in the middle of the U-shaped frame, and finally passes through between the two groups of second pulleys and then through the winding and unwinding machine, and the winch performs the winding work.

[0012] Preferably, two groups of second fixed collar sleeves are transversely installed at the upper end of the traction bracket. Positioning pins are symmetrically arranged on both sides of the upper end of the traction bracket. The positioning pins pass through the first fixed collar sleeve and the second fixed collar sleeve. According to the environmental conditions of the operation room, the positioning pins are passed through the first fixed collar sleeve and the second fixed collar sleeve to adjust the angle between the traction bracket and the U-shaped support plate, improving the flexibility of the traction device.

[0013] Preferably, handles are symmetrically installed on both sides of one surface of the traction bracket, and an I-shaped frame is installed below the surface of the traction bracket away from the handles. When the steel cable is towed to the second traction box, the operation of the traction device ends. At this time, the steel cable is untied, and by lifting the handles, the traction bracket is retracted upward without blocking the second traction box from continuing to tow the steel wire tube.

[0014] Preferably, a traction head is provided in the extending direction of the steel cable. A disc is installed on one surface of the traction head. A plurality of steel wire bodies are towed on the traction head. A plurality of positioning columns are circumferentially installed at the edge of one surface of the disc. A plurality of traction rings are circumferentially installed inside the disc where the positioning columns are installed. The steel wire bodies of the steel wire tube are pressed against the traction head, and then the steel cable of the traction bracket is passed through the traction rings and fixed, and then the traction work can start. During this process, the positioning columns can prevent deviation during traction, improving the stability of the traction device.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The steel cable is passed through the retractor along the traction bracket and the U-shaped support plate, and is tightened or released by the winch. This method can avoid the situation where the outer wall of the guiding pipe scratches the sealing ring of the negative pressure cooling box during the installation of the guiding pipe. During this process, if the guiding pipe is used for transmission, production line failures may occur due to problems such as wear, blockage, or fracture of the guiding pipe, and the guiding pipe needs to be installed manually, which is time-consuming and laborious. However, using the traction bracket directly towes the steel wire tube mechanically, reducing potential failure points in this link and improving the stability and reliability of the production line;

[0017] 2. During the winding process of the steel cable, when the steel cable is tightened or released to a certain angle, the limiting rod touches the limiter, and the limiting block will stop to prevent excessive tightening or release, resulting in a change in the angle of the steel wire tube and being unable to be smoothly towed to the second traction box, improving the safety of the traction device;

[0018] 3. According to the environmental conditions of the operation room, the positioning pins are passed through the first fixed collar sleeve and the second fixed collar sleeve to adjust the angle between the traction bracket and the U-shaped support plate, improving the flexibility of the traction device.

[0026] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figures 1-6, the present utility model provides an embodiment: a traction device for preparing a steel wire tube, including a load-bearing base 1, a winch 2, a winding and unwinding machine 3, a U-shaped support plate 4 and a steel cable 5; a winch 2 and a winding and unwinding machine 3 are linearly installed above the load-bearing base 1, a U-shaped support plate 4 is installed on one side of the load-bearing base 1 away from the winch 2, and a steel cable 5 passes through the winch 2, the winding and unwinding machine 3 and the U-shaped support plate 4. One end of the U-shaped support plate 4 away from the load-bearing base 1 is installed with a U-shaped frame 402, a first pulley 403 is installed in the middle of the U-shaped frame 402, the lower end of the U-shaped support plate 4 is installed with an L-shaped support plate 408, and four groups of first fixed ring sleeves 409 fixedly connected to the U-shaped support plate 4 are horizontally installed on one side of the upper end of the L-shaped support plate 408. A traction bracket 412 is provided below the first fixed ring sleeve 409. A second support rod 415 is horizontally installed at the bottom of the traction bracket 412. Two vertical plates 416 are horizontally installed in the middle of the side of the second support rod 415 away from the I-shaped frame 414. A fourth pulley 417 is installed between the two vertical plates 416.

[0028] Please refer to Figure 2 , in this embodiment, a placement table 101 fixedly connected to the load-bearing base 1 is provided on one side of the winch 2. A speed reducer 102 (the model of the speed reducer 102 is DCY315-50-1S) is installed on the upper end of the placement table 101. A motor 103 fixedly connected to the placement table 101 is provided on one side of the speed reducer 102. Two rectangular mounting sleeves 104 are horizontally installed on the side of the base where the U-shaped support plate 4 is installed. An installation column 105 passes through the middle of the rectangular mounting sleeve 104. A nut 106 is sleeved outside the installation column 105. Driven by the motor 103, the winch 2 tightens or releases the steel cable 5. In this process, through the action of the speed reducer 102, the speed of the steel cable 5 being wound and unwound is balanced, and the practicability and flexibility of the steel cable 5 during winding are improved.

A limit rod 303 passes through the middle of the circular hole opened in the limit block 304. During the winding process of the steel cable 5, when the steel cable 5 is tightened or released to a certain angle, the limit rod 303 touches the limiter 302, and the limit block 304 will stop, preventing excessive tightening or release, resulting in a change in the angle of the steel wire tube and making it impossible to smoothly tow it to the second traction box, thereby improving the safety of the traction device.

[0029] Please refer to Figures 3-5, in this embodiment, first support rods 401 are installed in the middle of both ends of the U-shaped support plate 4. A rectangular fixing block 404 fixedly connected to the U-shaped support plate 4 is provided on one side of the U-shaped frame 402. The first support rods 401 provide stable support for the U-shaped support plate 4, preventing it from skewing during the process of pulling the towing cable 5 and avoiding affecting the shape, dimensions, and performance of the cable 5. Above the rectangular fixing block 404, there is a rectangular cover plate 405. Two groups of second pulleys 406 are horizontally installed between the rectangular cover plate 405 and the rectangular fixing block 404. A U-shaped groove is formed at the edge of the side of the U-shaped support plate 4 away from the load-bearing base 1. A third pulley 407 is installed in the middle of the U-shaped support plate 4 where the U-shaped groove is formed. The cable 5 first passes through the fourth pulley 417 between the two vertical plates 416, then through the third pulley 407, then through the first pulley 403 in the middle of the U-shaped frame 402, and finally passes through between the two groups of second pulleys 406 and then through the winch 3, and the winding work is carried out by the hoist 2. Two groups of second fixing collar sleeves 411 are horizontally installed at the upper end of the traction bracket 412. Positioning pins 410 are symmetrically provided on both sides of the upper end of the traction bracket 412. The positioning pins 410 pass through the first fixing collar sleeve 409 and the second fixing collar sleeve 411. According to the environmental conditions of the operation room, the positioning pins 410 are passed through the first fixing collar sleeve 409 and the second fixing collar sleeve 411 to adjust the angle between the traction bracket 412 and the U-shaped support plate 4, improving the flexibility of the traction device. On both sides of one side of the traction bracket 412, handles 413 are symmetrically installed. Below the side of the traction bracket 412 away from the handle 413, an I-shaped frame 414 is installed. When the cable 5 is pulled to the second traction box, the traction device finishes working. At this time, the cable 5 is untied, and by lifting the handle 413, the traction bracket 412 is retracted upward without blocking the second traction box for continued pulling of the wire tube.

[0030] Please refer to Figure 6 , in this embodiment, a traction head 6 is provided in the extending direction of the cable 5. A disc 601 is installed on one side of the traction head 6. A plurality of wire bodies 604 are tractionally provided on the traction head 6. A plurality of positioning columns 603 are circumferentially installed at the edge of one side of the disc 601. A plurality of traction rings 602 are circumferentially installed inside the disc 601 where the positioning columns 603 are installed. The wire bodies 604 of the wire tube are pressed against the traction head 6, and then the cable 5 of the traction bracket 412 is passed through the traction ring 602 and fixed, and then the traction work can be started. During this process, the positioning columns 603 can prevent deviation during traction and improve the stability of the traction device.

[0031] When working, first press the steel wire body 604 of the steel wire tube against the traction head 6. Then fix the steel cable 5 of the traction bracket 412 after passing it through the traction ring 602, and the traction work can start. First, lift the U-shaped support plate 4 and pass it through the rectangular installation sleeve 104. Then the installation column 105 passes through the rectangular installation sleeve 104 and is positioned and connected to the U-shaped support plate 4, and then tightened and fixed by the nut 106. Then, according to the environmental conditions of the operation room, pass the positioning pin 410 through the first fixed ring sleeve 409 and the second fixed ring sleeve 411 to adjust the angle between the traction bracket 412 and the U-shaped support plate 4. After all adjustments are completed, first pass the steel cable 5 through the fourth pulley 417 between the two vertical plates 416, then through the third pulley 407, then through the first pulley 403 in the middle of the U-shaped frame 402, and finally pass through between the two second pulleys 406, and then through the winch 3. Immediately afterwards, driven by the motor 103, drive the hoist 2 to tighten or release the steel cable 5. During this process, through the function of the reducer 102, balance the speed of the steel cable 5 being wound and released;

[0032] During the winding process of the steel cable 5, when the steel cable 5 is tightened or released to a certain angle, the limit rod 303 touches the stopper 302, and the limit block 304 will stop to prevent excessive tightening or release, resulting in a change in the angle of the steel wire tube and unable to be smoothly pulled to the second traction box;

[0033] When the steel cable 5 is pulled to the second traction box, the traction device ends its work. At this time, untie the steel cable 5, and by lifting the handle 413, lift up the traction bracket 412 to not block the second traction box from continuing to pull the steel wire tube.

[0034] Through the above steps, pass the steel cable 5 along the traction bracket 412 and the U-shaped support plate 4 through the winch 3 and tighten or release it through the hoist 2. This method can avoid the situation where the outer wall of the guiding tube scratches the sealing ring of the negative pressure cooling box during the installation of the guiding tube. During this process, if a guiding tube conveyor is used, production line failures may occur due to problems such as wear, blockage, or breakage of the guiding tube, and the guiding tube needs to be installed manually, which is time-consuming and laborious. However, using the traction bracket 412 directly pulls the steel wire tube mechanically, reducing potential failure points in this link, improving the stability and reliability of the production line, so as to solve the problem that the existing second-stage guiding tube is relatively heavy, and its outer wall may scratch the sealing ring of the negative pressure cooling box during installation, affecting the smoothness of the outer wall of the steel wire tube.
