Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction equipment technology, and in particular to a traction device for wire and cable construction. Background Technology
[0002] When laying wires and cables, it is necessary to pull them. Traditional wire and cable pulling devices are mostly placed directly outdoors and pulled manually by construction workers. When wires and cables are left exposed outdoors for a long time, a lot of dust and impurities tend to accumulate on their surface.
[0003] The existing technology CN220078224U discloses a wire and cable pulling device, which includes a base and a support frame symmetrically welded to its top surface. A wire-feeding shaft is connected to the near end face of the symmetrical support frame via bearings. A protective shell is snapped onto the near end face of the symmetrical support frame, and the protective shell is located directly above the wire-feeding shaft. A guide plate is welded to the bottom end of the protective shell. A limiting groove is formed inside the guide plate, and a cleaning brush is adhered to the inner wall of the limiting groove. A dust collection box is slidably connected to the near end face of the symmetrical support frame, and the dust collection box is located directly below the wire-feeding shaft. A support rail is welded to the top surface of the base, and a guide slider is slidably connected to the outer wall of the support rail. Guide rollers are symmetrically connected to the inner wall of the guide slider via bearings. The operator can guide the wire or cable by pulling the moving end through the guide rollers connected to the inner wall of the guide slider via the symmetrical bearings. The support frame, wire-feeding shaft, protective shell, guide plate, dust collection box, limiting groove, and cleaning brush are designed to protect the wire or cable and clean it during movement, thereby improving the wire-feeding efficiency of the device.
[0004] However, using the above method, the inner wall of the guide slider connects two guide rollers through bearings. The distance between the two guide rollers is fixed, which can only provide guidance for wires and cables with a single outer diameter and cannot be applied to wires and cables with different outer diameters, resulting in a limited range of applications. Utility Model Content
[0005] The purpose of this utility model is to provide a wire and cable construction traction device, which aims to solve the problem that existing wire and cable traction devices can only guide wires and cables of a single outer diameter and cannot be applied to wires and cables of different outer diameters, resulting in a limited range of applications.
[0006] To achieve the above objectives, this utility model provides a wire and cable construction traction device, including a base and a traction assembly. The traction assembly includes two support seats, a wire feeding roller, a lifting component, two horizontal shafts, and a sliding component.
[0007] Two support seats are fixedly connected to the base and located on the top of the base respectively; the wire feeding rollers are rotatably connected to the two support seats and located between the two support seats; the lifting component includes a guide rail, a bidirectional threaded screw, two sliders, and two first bearings; the guide rail is fixedly connected to the base and located on the top of the base; the bidirectional threaded screw is rotatably connected to the guide rail and passes through the guide rail; the two sliders are slidably connected to the guide rail and threadedly connected to the bidirectional threaded screw respectively, and are located inside the guide rail respectively; the outer rings of the two first bearings are fixedly connected to the two sliders respectively and are located on the sides of the two sliders respectively; the two horizontal shafts are fixedly connected to the inner rings of the two first bearings respectively and are located on the sides of the two first bearings respectively; the sliding component is disposed on the top of the base.
[0008] The lifting component also includes a knob; the knob is fixedly connected to the bidirectional threaded screw and is located at the top of the bidirectional threaded screw.
[0009] The sliding component includes a moving block and a limiting frame; the moving block is slidably connected to the base and is located on top of the base; the limiting frame is fixedly connected to the moving block and is located on top of the moving block, and the limiting frame has two guide grooves located on both sides of the limiting frame.
[0010] The sliding component further includes two guide members; the two guide members are respectively disposed on the side of the limiting frame.
[0011] The guide component includes a vertical shaft, two second bearings, two screws, and two nuts. The vertical shaft is located inside the limiting frame. The outer rings of the two second bearings are fixedly connected to the vertical shaft and located on both sides of the vertical shaft. The two screws are fixedly connected to the inner rings of the two second bearings and located on the sides of the two second bearings. The two nuts are threadedly connected to the two screws and located on the sides of the two screws. The limiting frame has two strip grooves located on both sides of the limiting frame.
[0012] This utility model discloses a cable traction device for construction. The cable is wound around a pay-off drum. During construction, when traction is required, the moving end of the cable is removed from the pay-off drum and passed through a sliding component, allowing the cable to pass between two horizontal shafts. The sliding component and the two horizontal shafts provide limiting guidance for the cable. A bidirectional threaded rod has external threads with opposite directions at both ends. Two sliders are located at opposite ends of the bidirectional threaded rod. A guide rail guides the sliding of the sliders and restricts their rotation. By rotating the bidirectional threaded rod clockwise or counterclockwise, the two sliders slide along the guide rail in directions closer or further apart. The two sliders drive the two horizontal shafts closer or further apart, thereby adjusting the distance between the two horizontal shafts to accommodate cables of different outer diameters. This device provides guidance for cables of different outer diameters, solving the problem that existing cable traction devices can only guide cables of a single outer diameter and are not applicable to cables of different outer diameters, resulting in a limited range of applications. The first bearing allows the horizontal shaft to rotate smoothly, preventing obstruction when the wires and cables move between the two horizontal shafts. Attached Figure Description

[0021] This utility model provides a wire and cable construction traction device, including a base 101 and a traction assembly. The traction assembly includes two support seats 102, a wire-laying roller 103, a lifting component 104, two horizontal shafts 105, and a sliding component 106. The lifting component 104 includes a guide rail 107, a bidirectional threaded screw 108, two sliders 109, two first bearings 110, and a knob 111. The sliding component 106 includes a moving block 112, a limiting frame 113, and two guide members 115. The guide member 115 includes a vertical shaft 116, two second bearings 117, two screws 118, and two nuts 119. The aforementioned solution solves the problem that existing wire and cable traction devices can only provide guidance for wires and cables with a single outer diameter, and cannot be applied to wires and cables with different outer diameters, resulting in a limited range of applications.
[0022] In this specific embodiment, the two support seats 102 are respectively fixedly connected to the base 101 and are located on the top of the base 101; the wire feeding roller 103 is rotatably connected to the two support seats 102 and is located between the two support seats 102; the lifting component 104 includes a guide rail 107, a bidirectional threaded screw 108, two sliders 109, and two first bearings 110; the guide rail 107 is fixedly connected to the base 101 and is located on the top of the base 101; the bidirectional threaded screw 108 and the guide rail 107 rotate. The guide rail 107 is connected and passes through it; the two sliders 109 are slidably connected to the guide rail 107 and threadedly connected to the bidirectional threaded screw 108, and are located inside the guide rail 107; the outer rings of the two first bearings 110 are fixedly connected to the two sliders 109 and are located on the sides of the two sliders 109; the two horizontal shafts 105 are fixedly connected to the inner rings of the two first bearings 110 and are located on the sides of the two first bearings 110; the sliding component 106 is disposed on the top of the base 101. The wire and cable are wound on the pay-off roller 103. During construction, when the wire and cable need to be pulled, the moving end of the cable is removed from the pay-off roller 103 and passed through the sliding member 106, allowing the cable to pass between the two horizontal shafts 105. The sliding member 106 and the two horizontal shafts 105 provide limiting guidance for the cable. The bidirectional threaded screw 108 has external threads with opposite thread directions at both ends. The two sliders 109 are located at the opposite ends of the bidirectional threaded screw 108. The guide rail 107 guides the sliding of the sliders 109 and restricts their rotation. By rotating the bidirectional threaded screw 108 forward or backward, the operator causes the two sliders 109 to slide along the guide rail 107 in a direction that moves closer to or further away from each other. The two sliders 109 then move the two horizontal shafts 105 closer to or further away from each other, thereby adjusting the distance between the two horizontal shafts 105 to accommodate wires and cables of different outer diameters. This provides guidance for wires and cables of different outer diameters, solving the problem that existing wire and cable traction devices can only guide wires and cables of a single outer diameter, thus limiting their applicability. The first bearing 110 ensures smooth rotation of the horizontal shafts 105, preventing obstruction when the wires and cables move between the two horizontal shafts 105.
[0023] The knob 111 is fixedly connected to the bidirectional threaded screw 108 and is located at the top of the bidirectional threaded screw 108. The operator can easily rotate the bidirectional threaded screw 108 by holding the knob 111.
[0024] Secondly, the movable block 112 is slidably connected to the base 101 and is located on top of the base 101; the limiting frame 113 is fixedly connected to the movable block 112 and is located on top of the movable block 112. The limiting frame 113 has two guide grooves 114, which are located on both sides of the limiting frame 113. The guide grooves 114 are adapted to the horizontal axis 105, which can move longitudinally within the guide grooves 114. The movable block 112 is T-shaped, and the base 101 has a sliding groove adapted to the movable block 112. When the cable passes through the limiting frame 113 and the two horizontal axes 105, if the angle of movement of the cable is too large, the movable block 112 slides along the base 101 to limit its movement range.
[0025] Meanwhile, the two guide members 115 are respectively disposed on the side of the limiting frame 113. The two guide members 115 can limit and guide the horizontal position of the wires and cables.
[0026] In addition, the vertical shaft 116 is located inside the limiting frame 113; the outer rings of the two second bearings 117 are fixedly connected to the vertical shaft 116 and located on both sides of the vertical shaft 116; the two screws 118 are fixedly connected to the inner rings of the two second bearings 117 and located on the sides of the two second bearings 117; the two nuts 119 are threadedly connected to the two screws 118 and located on the sides of the two screws 118; the limiting frame 113 has two strip grooves 120, and the two strip grooves 120 are located on both sides of the limiting frame 113. The moving end of the wire / cable passes between the two horizontal axes 105 and the two vertical axes 116. The two horizontal axes 105 restrict the longitudinal position of the wire / cable, and the two vertical axes 116 restrict the lateral position of the wire / cable, thereby providing limiting guidance for the movement of the wire / cable. When it is necessary to guide wires / cables with different outer diameters, the two nuts 119 are unscrewed from the screw 118, and the screw 118 is slid along the strip groove 120. The distance between the two vertical axes 116 can be adjusted according to the outer diameter of the wire / cable. After the position of the vertical axis 116 is adjusted, the nuts 119 are tightened on the screw 118. The second bearing 117 ensures that the vertical axis 116 rotates simultaneously when the wire / cable moves, preventing the vertical axis 116 from interfering with the movement of the wire / cable.
[0027] When using this invention, the wire and cable are wound around the pay-off roller 103. During construction, when the wire and cable need to be pulled, the moving end of the cable is removed from the pay-off roller 103 and passed between the two horizontal shafts 105 and the two vertical shafts 116. The two horizontal shafts 105 restrict the longitudinal position of the wire and cable, and the two vertical shafts 116 restrict the lateral position of the wire and cable, thus providing limiting guidance for the movement of the wire and cable. When guiding wires and cables of different outer diameters, the operator rotates the bidirectional threaded screw 108 clockwise or counterclockwise. The rotation of the bidirectional threaded screw 108 causes the two sliders 109 to slide along the guide rail 107 in a direction that brings them closer to or further away from each other. 09 drives the two horizontal shafts 105 to move closer or further apart, thereby adjusting the distance between the two horizontal shafts 105 to accommodate wires and cables of different outer diameters; unscrewing the two nuts 119 from the screw 118 and then sliding the screw 118 along the strip groove 120 allows adjustment of the distance between the two vertical shafts 116 according to the outer diameter of the wire and cable; after the position of the vertical shafts 116 is adjusted, the nuts 119 are tightened onto the screw 118; this utility model can provide guidance for wires and cables of different outer diameters, thus solving the problem that existing wire and cable traction devices can only provide guidance for wires and cables of a single outer diameter and cannot be applied to wires and cables of different outer diameters, resulting in a limited range of applications.
