Description

Technical Field

[0001] This utility model relates to the field of cable laying auxiliary equipment technology, and in particular to a cable roller with a steering function used in electromechanical engineering. Background Technology

[0002] In electromechanical engineering, large equipment installation, and power construction, it is often necessary to lay and install power cables or control cables with large cross-sections and heavy weight. The cable laying paths are usually complex and varied, inevitably requiring multiple turns.

[0003] Cable rollers are widely used in construction to effectively guide cables at bends, reduce traction friction during laying, and protect the cable sheath from damage. Currently, to accommodate cable routes at different angles, some cable rollers are designed with steering capabilities, for example, by mounting the roller mechanism on a horizontally rotatable base.

[0004] However, existing cable rollers with steering functions generally suffer from a core flaw: the lack of a fast, reliable, and easy-to-operate angle locking mechanism. When heavy cables pass through these rollers under tension, the cable's own stiffness and traction generate a significant lateral force. This force can easily cause unintended deflection of the roller base if it is not effectively locked. This unintended deflection not only causes the cable laying path to deviate from the preset angle and increases friction between the cable and the roller sidewall, but may even cause the cable to slip off the roller and cause damage. Currently, some temporary fixing methods are cumbersome, time-consuming, and labor-intensive, failing to meet the high-efficiency operational requirements of rapid adjustment and immediate fixation on construction sites.

[0005] Therefore, this utility model proposes a steering function for use in electromechanical engineering to overcome the shortcomings of the prior art. Utility Model Content To overcome the above shortcomings, this utility model provides a cable roller with a steering function for electromechanical engineering. It aims to improve the problem that existing cable rollers with steering functions in electromechanical engineering lack a fast, labor-saving and reliable locking positioning mechanism after the steering angle is adjusted, which makes the cable prone to unexpected deflection when under force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable roller with steering function for use in electromechanical engineering, comprising a base and a steering roller mechanism; The steering roller mechanism includes an inner ring of a slewing bearing and an outer ring of a slewing bearing. The inner ring of the slewing bearing is fixedly connected to the top of the base, and the outer ring of the slewing bearing is rotatably connected to the outside of the inner ring of the slewing bearing. It also includes a handle locking mechanism. The handle locking mechanism includes a push rod, a locking block, an eccentric wrench, and an unlocking spring. The push rod is slidably disposed inside the base, and the locking block is fixedly connected to one end of the push rod. A retaining ring adapted to the retaining block is fixed on the outer ring of the slewing bearing; The eccentric wrench is pivotally connected to the side wall of the base via a fixed pivot, and the eccentric end of the eccentric wrench abuts against the other end of the push rod. The unlocking spring is disposed inside the base, and the elastic force of the unlocking spring is used to push the locking tooth block of the push rod to disengage from the locking tooth ring; Preferably, the steering roller mechanism further includes a steering bracket, which is fixedly connected to the top of the outer ring of the slewing bearing, and a sub-roller is rotatably connected to the steering bracket via a pin. Preferably, the outer peripheral sidewall of the sub-roller is provided with a guide groove for defining the cable turning segment; Preferably, the base has mounting holes at its bottom for mounting bolts, which pass through the mounting holes to fix the base. Preferably, the two ends of the unlocking spring abut against the inner end wall of the base and the boss or end face on the push rod, respectively; Preferably, when the eccentric wrench rotates around the fixed pivot, the eccentric end of the eccentric wrench pushes the push rod to slide within the base against the elastic force of the unlocking spring; Preferably, the direction of the spring force applied by the unlocking spring to the push rod is opposite to the direction of the thrust applied by the eccentric end of the eccentric wrench to the push rod when it is in the locked position; Preferably, the teeth of the locking block are adapted to mesh with the tooth grooves of the locking ring to achieve rotational locking of the outer ring of the slewing bearing.

[0007] This utility model has the following beneficial effects: 1. This utility model solves the problems of inconvenient cable roller steering adjustment and inability to quickly and reliably fix the steering angle after adjustment by setting a steering roller mechanism that can rotate horizontally on the base, and adding a handle locking mechanism controlled by an eccentric wrench between the steering roller mechanism and the base. It achieves the effect of flexible and smooth steering adjustment and reliable and stable locking and positioning.

[0008] 2. This utility model uses an eccentric wrench to drive a push rod, which in turn drives the locking block to engage or disengage with the locking ring fixed on the outer ring of the slewing bearing. The unlocking spring is used to achieve unlocking and reset. This solves the problems of existing locking mechanisms being laborious to operate, having insufficient locking force, or being complex in structure. It achieves the effects of compact structure, labor-saving operation, fast locking, and firm and reliable locking.

[0009] 3. This utility model solves the problems of cable being easily damaged due to high friction and slipping off the roller during turning by setting a sub-roller that rotates through a pin on the turning bracket and opening a guide groove on the sub-roller to limit the cable turning angle. It achieves the effects of low frictional resistance, stable guidance, effective protection of the cable sheath and prevention of cable deviation when the cable turns. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figures 1-5 The present invention provides an embodiment of a cable roller with a steering function for use in electromechanical engineering, comprising a base 2 and a steering roller mechanism 4. The bottom of the base 2 is provided with mounting holes for mounting bolts 3, and the bolts 3 pass through the mounting holes to fix the base 2. The steering roller mechanism 4 includes a slewing bearing inner ring 406, a slewing bearing outer ring 405, and a steering bracket 404. The slewing bearing inner ring 406 is fixedly connected to the top of the base 2, the slewing bearing outer ring 405 is rotatably connected to the outside of the slewing bearing inner ring 406, and the steering bracket 404 is fixedly connected to the top of the slewing bearing outer ring 405. A sub-roller 401 is rotatably connected to the steering bracket 404 via a pin 402. The outer peripheral sidewall of the sub-roller 401 is provided with a guide groove 403 for defining the cable turning section 1. It also includes a handle locking mechanism 5, which includes a push rod 506, a toothed block 504, an eccentric wrench 501, an unlocking spring 505, and a toothed ring 503 fixed on the outer ring 405 of the slewing bearing. The push rod 506 is slidably disposed inside the base 2, and the tooth block 504 is fixedly connected to one end of the push rod 506. The teeth of the tooth block 504 are adapted to mesh with the tooth groove of the tooth ring 503 to achieve rotational locking of the outer ring 405 of the slewing bearing. The eccentric wrench 501 is pivotally connected to the side wall of the base 2 via a fixed pivot 502, and the eccentric end of the eccentric wrench 501 abuts against the other end of the push rod 506. The unlocking spring 505 is located inside the base 2. The two ends of the unlocking spring 505 abut against the inner end wall of the base 2 and the boss or end face on the push rod 506, respectively. The elastic force of the unlocking spring 505 is used to push the tooth block 504 of the push rod 506 to disengage from the tooth ring 503. When the eccentric wrench 501 rotates around the fixed pivot 502, the eccentric end of the eccentric wrench 501 pushes the push rod 506 to slide within the base 2 against the elastic force of the unlocking spring 505. The direction of the elastic force applied by the unlocking spring 505 to the push rod 506 is opposite to the direction of the pushing force applied by the eccentric end of the eccentric wrench 501 to the push rod 506 when it is in the locked position. The handle locking mechanism 5 includes a push rod 506, a locking block 504, an eccentric wrench 501, and an unlocking spring 505; The push rod 506 is slidably disposed inside the base 2, and the locking block 504 is fixedly connected to one end of the push rod 506; The eccentric wrench 501 is pivotally connected to the side wall of the base 2 via a fixed pivot 502, and the eccentric end of the eccentric wrench 501 abuts against the other end of the push rod 506. The unlocking spring 505 is disposed inside the base 2, and the two ends of the unlocking spring 505 abut against the inner end wall of the base 2 and the boss or end face on the push rod 506 respectively. At the same time, a toothed ring 503 that is compatible with the toothed block 504 is fixed on the outer ring 405 of the slewing bearing of the steering roller mechanism 4. In the assembled state, the toothed block 504 and the toothed ring 503 are correspondingly arranged, and the teeth of the toothed block 504 are adapted to mesh with the tooth grooves of the toothed ring 503. This structure, which uses an eccentric wrench 501 to drive a push rod 506 and thereby control the selective engagement or disengagement of the toothed block 504 and the toothed ring 503, ensures that the handle locking mechanism 5 can quickly and reliably lock and unlock the rotation angle of the steering roller mechanism 4. In a preferred embodiment, the steering roller mechanism 4 further includes a steering bracket 404, which is fixedly connected to the top of the outer ring 405 of the slewing bearing, and a sub-roller 401 is rotatably connected to the steering bracket 404 via a pin 402. As another preferred embodiment, the outer peripheral sidewall of the sub-roller 401 is provided with a guide groove 403 for defining the cable corner section 1; As another preferred embodiment, the bottom of the base 2 is provided with mounting holes for mounting bolts 3, and the bolts 3 pass through the mounting holes to fix the base 2. In another preferred embodiment, the two ends of the unlocking spring 505 abut against the inner end wall of the base 2 and the boss or end face on the push rod 506, respectively. In another preferred embodiment, when the eccentric wrench 501 rotates around the fixed rotating shaft 502, the eccentric end of the eccentric wrench 501 pushes the push rod 506 to slide within the base 2 against the elastic force of the unlocking spring 505. In another preferred embodiment, the direction of the spring force applied by the unlocking spring 505 to the push rod 506 is opposite to the direction of the pushing force applied by the eccentric end of the eccentric wrench 501 to the push rod 506 when it is in the locked position. In another preferred embodiment, the teeth of the locking block 504 are adapted to mesh with the tooth grooves of the locking ring 503 to achieve rotational locking of the outer ring 405 of the slewing bearing.

[0014] Working principle: When the angle of the steering roller mechanism 4 needs to be adjusted, the operator turns the eccentric wrench 501 pivotally connected to the side wall of the base 2. The eccentric wrench 501 rotates around the fixed rotating shaft 502, so that the eccentric end of the eccentric wrench 501 is released from the pressure on the other end of the push rod 506. At this time, the unlocking spring 505 set inside the base 2 releases its elastic force. The elastic force of the unlocking spring 505 pushes the push rod 506 to slide inside the base 2. The push rod 506 drives the toothed block 504 fixedly connected to one end to disengage from the toothed ring 503. Since the toothed ring 503 is fixedly connected to the outer ring 405 of the slewing bearing, the outer ring 405 of the slewing bearing is unlocked at this time and can rotate freely relative to the inner ring 406 of the slewing bearing fixedly connected to the top of the base 2. After unlocking, the steering bracket 404, which is fixedly connected to the top of the outer ring 405 of the slewing bearing, can rotate. When the cable corner segment 1 is placed in the guide groove 403 of the sub-roller 401 and is pulled, the cable corner segment 1 drives the sub-roller 401 to rotate around the pin 402 and pushes the entire steering bracket 404 to rotate to the target angle. During this process, the sub-roller 401 always maintains low friction contact with the cable corner segment 1, and the guide groove 403 limits the cable corner segment 1 to prevent it from deviating. When the steering bracket 404 rotates to the target angle, the operator reverses the operation of the eccentric wrench 501. The eccentric end of the eccentric wrench 501 rotates and presses the other end of the push rod 506, pushing the push rod 506 to slide within the base 2 against the elastic force of the unlocking spring 505. This pushes the locking block 504, causing the teeth of the locking block 504 to mesh with the grooves of the locking ring 503. Since the direction of the elastic force applied by the unlocking spring 505 to the push rod 506 is opposite to the direction of the thrust applied by the eccentric end of the eccentric wrench 501 to the push rod 506 when it is in the locked position, the thrust of the eccentric wrench 501 ensures the reliable locking of the locking block 504 and the locking ring 503, thereby locking the rotation of the outer ring 405 of the slewing bearing and fixing the angle of the steering roller mechanism 4.
