Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sliding contact line support structure, specifically an adjustable sliding contact line support structure. Background Technology
[0002] In warehousing and logistics or industrial production scenarios, stacker cranes, as core material handling equipment, often need to work with production lines or warehousing systems to achieve 24-hour uninterrupted operation. The accompanying sliding contact line and current collector brush are key components to ensure the power supply and signal transmission of the equipment. That is, the sliding contact line needs to continuously transmit electrical energy and control signals, while the brush needs to be closely attached to the surface of the sliding contact line to build a stable conduction path through sliding contact.
[0003] However, if the machine is under high load conditions for a long time, such as frequent full-load lifting, rapid translation, and high-frequency start and stop, the contact surface between the sliding contact line and the brush will be continuously subjected to frictional stress. At this time, the surface of the sliding contact line is prone to wear and scratches, oxide layer peeling, and even local dents and deformation due to repeated friction. At the same time, the wear-resistant material of the brush will also be gradually worn down, resulting in a reduction in the contact surface of the brush head and edge wear and deformation. In some cases, frictional heat will accelerate material aging, resulting in brush head breakage or detachment. As wear intensifies, signal interruption will occur, which will lead to a decrease in the positioning accuracy of the stacker crane. In severe cases, there may even be a complete circuit break, and the stacker crane will stop directly. This will prevent the stacker crane from participating in material handling normally, disrupt the warehousing operation process, and affect the material supply of subsequent production links. To address this, we propose an adjustable sliding contact line support structure. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable sliding contact line support structure to solve the problems mentioned in the background art. When the machine is under high load conditions for a long time, such as frequent full-load lifting, rapid translation, and high-frequency start and stop, the contact surface between the sliding contact line and the brush will continuously bear frictional stress. At this time, the surface of the sliding contact line is prone to wear and scratches, oxide layer peeling, and even local dents and deformation due to repeated friction. At the same time, the wear-resistant material of the brush will gradually wear down, resulting in a reduction in the contact area of the brush head and edge wear and deformation. In some cases, frictional heat will accelerate material aging, resulting in brush head breakage or detachment. As wear intensifies, signal interruption will occur, leading to a decrease in the positioning accuracy of the stacker crane. In severe cases, there may even be a complete circuit break, causing the stacker crane to stop directly. This will prevent the stacker crane from participating in material handling normally, disrupt the warehousing operation process, and affect the material supply of subsequent production stages.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sliding contact line support structure, including a current collector cover, an adjustment component inside the current collector cover, a current collector adjustment bracket on the top of the adjustment component, a brush on the top of the current collector adjustment bracket, an elastic compensation component on the top of the brush, a current collector bracket fixedly mounted on one side of the current collector adjustment bracket, a current collector terminal fixing plate fixedly mounted on the inner side of the current collector bracket, a current collector terminal fixedly mounted on the top of the current collector terminal fixing plate, a ball spring pin on the side of the current collector adjustment bracket, a positioning bolt threadedly connected to the current collector adjustment bracket through a threaded hole on its side, and the current collector cover slidingly connected to the positioning bolt through a sliding hole inside its interior.
[0006] The adjustment component includes a movable frame, a current collector cover that is slidably connected to the movable frame via a sliding groove inside the current collector cover, a second limiting rod that is fixedly installed inside the current collector cover, a threaded rod that is rotatably connected inside the current collector cover, and a movable frame that is slidably connected to the second limiting rod via a sliding hole inside the movable frame.
[0007] The movable frame is internally fixedly equipped with a threaded sleeve, which is threadedly connected to the threaded rod through a threaded hole inside. One end of the accordion cover is fixedly installed inside the current collector cover, and the bottom end of the accordion cover is fixedly installed on the top of the movable frame. Accordion covers are provided on the outside of both the threaded rod and the second limit rod. The movable frame is threadedly connected to bolts through a threaded hole on one side.
[0008] The external thread of the bolt is connected to the slide rail. The movable frame is fixed to the slide rail by the bolt. The slide rail is slidably connected to the current collector adjustment bracket through the internal sliding groove. The slide rail is slidably connected to the positioning bolt and the ball spring pin through the internal sliding hole. A wear-resistant frame is fixedly installed at the bottom of the slide rail. The current collector adjustment bracket is located on the top surface of the wear-resistant frame.
[0009] The elastic compensation component includes a buckle, and the brush engages with the buckle through a slot inside the buckle. A connecting frame is fixedly installed on the top of the buckle, a compression spring is fixedly installed on the top of the connecting frame, a mounting frame is fixedly installed on the top of the compression spring, and a first limit rod is fixedly installed on the bottom of the mounting frame.
[0010] The compression spring is located outside the first limiting rod. The connecting frame is slidably connected to the first limiting rod through a sliding hole inside it. The connecting frame is threadedly connected to the limiting bolt through a threaded hole inside it. A wear-resistant frame is slidably connected to the outside of the limiting bolt. The wear-resistant frame is located on the top of the mounting frame. The mounting frame is slidably connected to the limiting bolt through a sliding hole inside it.
[0011] This utility model has at least the following beneficial effects: The adjustment components can adjust the height of the current collector separately. Specifically, through the threaded transmission of the threaded rod and threaded sleeve, the moving frame slides along the vertical slide groove, and the horizontal adjustment bracket of the current collector slides along the horizontal slide groove of the slide rail. This can flexibly adapt to different sliding contact line positions or equipment installation requirements. The bellows cover is fitted outside the threaded rod and the second limit rod and can extend and retract with the moving frame, effectively preventing dust and impurities from entering the adjustment mechanism, avoiding wear or jamming of parts, and ensuring the accuracy and service life of core structures such as the threaded transmission. The compression spring in the elastic compensation component can generate compensation force through its own elastic extension and contraction. When the brush wears due to long-term use or there is a slight deviation in the position of the sliding contact line, it can push the connecting frame and the buckle to move the brush synchronously, always ensuring that the brush and the sliding contact line are in close contact, avoiding unstable power supply due to poor contact.

Detailed Implementation
[0014] 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.
[0015] Please see Figures 1 to 7 This utility model provides a technical solution: an adjustable sliding contact line support structure, including a current collector cover 1, an adjustment component 4 inside the current collector cover 1, a current collector adjustment bracket 5 on the top of the adjustment component 4, a brush 6 on the top of the current collector adjustment bracket 5, an elastic compensation component 2 on the top of the brush 6, a current collector bracket 8 fixedly installed on one side of the current collector adjustment bracket 5, a current collector terminal fixing plate 3 fixedly installed on the inner side of the current collector bracket 8, a current collector wiring terminal 7 fixedly installed on the top of the current collector terminal fixing plate 3, a ball spring pin 10 on the side of the current collector adjustment bracket 5, a positioning bolt 9 threadedly connected to the current collector adjustment bracket 5 through a threaded hole on its side, and a current collector cover 1 slidably connected to the positioning bolt 9 through a sliding hole inside its interior.
[0016] The adjusting assembly 4 includes a movable frame 41. A current collector cover 1 is slidably connected to the movable frame 41 via a sliding groove inside the cover. A second limiting rod 42 is fixedly installed inside the current collector cover 1. A threaded rod 46 is rotatably connected inside the current collector cover 1. The movable frame 41 is slidably connected to the second limiting rod 42 via a sliding hole inside the cover. A threaded sleeve 47 is fixedly installed inside the movable frame 41, and the threaded sleeve 47 is threadedly connected to the threaded rod 46 via a threaded hole inside the sleeve. One end of a bellows cover 45 is fixedly installed inside the current collector cover 1, and the bottom end of the bellows cover 45 is fixedly installed on the top of the movable frame 41. Bellows covers 45 are provided on the outside of both the threaded rod 46 and the second limiting rod 42. A bolt 48 is threadedly connected to the movable frame 41 via a threaded hole on one side. A slide rail 44 is threadedly connected to the outside of the bolt 48. The movable frame 41 is held in place by the bolt 48 and the slide rail 44. The slide rail 44 is slidably connected to the current collector adjustment bracket 5 through its internal sliding groove. The slide rail 44 is slidably connected to the positioning bolt 9 and the ball spring pin 10 through its internal sliding hole. The bottom of the slide rail 44 is fixedly installed with the support frame 43. The current collector adjustment bracket 5 is located on the top surface of the support frame 43. By rotating the vertical threaded rod 46 inside the current collector cover 1, the moving frame 41 and the threaded sleeve 47 are driven to slide up and down along the second limit rod 42 and the vertical sliding groove of the current collector cover 1 through the thread transmission, so as to realize the height adjustment of the current collector adjustment bracket 5. The bellows cover 45 can extend and retract with the moving frame 41 to prevent dust. When adjusting horizontally, after loosening the positioning bolt 9, the current collector adjustment bracket 5 slides along the horizontal sliding groove of the slide rail 44. The ball spring pin 10 is stabilized by the ball friction reduction and spring force. After it is in place, tighten the positioning bolt 9 to press against the inner wall of the sliding hole of the current collector cover 1 to complete the position locking.
[0017] The elastic compensation component 2 includes a buckle 27. The brush 6 engages with the buckle 27 via a slot inside the buckle 27. A connecting frame 24 is fixedly mounted on the top of the buckle 27. A compression spring 26 is fixedly mounted on the top of the connecting frame 24. A mounting frame 23 is fixedly mounted on the top of the compression spring 26. A first limiting rod 25 is fixedly mounted on the bottom of the mounting frame 23. The compression spring 26 is located outside the first limiting rod 25. The connecting frame 24 is slidably connected to the first limiting rod 25 via a sliding hole inside the connecting frame 24. A limiting bolt 21 is threadedly connected to the connecting frame 24 via a threaded hole inside the connecting frame 24. A wear-resistant frame 22 is slidably connected to the outside of the limiting bolt 21. The wear-resistant frame 22 is located on top of the mounting frame 23. The mounting frame 23 is slidably connected to the limiting bolt 21 via a sliding hole inside the mounting frame 23. The brush 6 engages with the buckle 27 via a slot inside the mounting frame 27. The slot engages with the buckle 27. The connecting bracket 24 fixed at the top of the buckle 27 is connected to the compression spring 26 at the bottom of the mounting bracket 23. The compression spring 26 uses elastic extension and contraction to generate a compensating force, pushing the connecting bracket 24 to drive the buckle 27 and the brush 6 to move synchronously, ensuring that the brush 6 is always in close contact with the sliding contact line to compensate for wear or positional deviation. The first limiting rod 25 fixed at the bottom of the mounting bracket 23 passes through the sliding hole of the connecting bracket 24 to limit the offset of the connecting bracket 24. At the same time, the limiting bolt 21 connected to the connecting bracket 24 through the internal threaded hole passes through the sliding hole of the wear-resistant frame 22 and the sliding hole of the mounting bracket 23. This reduces the frictional wear between the limiting bolt 21 and the mounting bracket 23 through the wear-resistant frame 22, and limits the movement range of the limiting bolt 21 through the sliding hole, preventing the connecting bracket 24 from sliding excessively and causing damage to the compression spring 26.
[0018] Because the current collector cover 1 has a vertical sliding groove inside that slides with the movable frame 41, and a second limiting rod 42 is fixed inside, the second limiting rod 42 restricts the movable frame 41 to move only in a straight line to prevent deviation. A threaded sleeve 47 is fixed inside the movable frame 41, and the threaded sleeve 47 is threadedly engaged with a vertically threaded rod 46 rotatably connected inside the current collector cover 1. When the current collector needs to be adjusted in height, the threaded rod 46 is rotated, which drives the threaded sleeve 47 and the movable frame 41 to move along the second vertical groove. The limit rod 42 and the vertical slide groove of the current collector cover 1 slide up and down. One end of the bellows cover 45 is fixed inside the current collector cover 1, and the other end is fixed to the top of the movable frame 41. It is also fitted over the threaded rod 46 and the second limit rod 42, and can extend and retract with the movable frame 41 to prevent dust and impurities from entering the adjustment mechanism and affecting accuracy. The movable frame 41 is connected to the bolt 48 through the side threaded hole. The bolt 48 is threaded with the slide rail 44. Tightening the bolt 48 can fix the slide rail 44 on the movable frame 41. The slide rail 44 is internally designed with... The horizontal sliding groove slides in conjunction with the current collector adjustment bracket 5, and the bottom of the slide rail 44 is fixed with the support frame 43. The current collector adjustment bracket 5 is placed on the top surface of the support frame 43. When adjusting the current collector adjustment bracket 5 horizontally, first loosen the positioning bolt 9 on the side of the current collector adjustment bracket 5. The positioning bolt 9 originally passed through the threaded hole of the current collector adjustment bracket 5 and slid in conjunction with the matching horizontal sliding hole inside the current collector cover 1, which played a temporary positioning role. After loosening, the current collector adjustment bracket 5 can slide left and right along the horizontal sliding groove of the slide rail 44. At this time, the ball spring pin 10 on the side of the current collector adjustment bracket 5 is embedded in the sliding hole of the slide rail 44. On the one hand, the ball reduces horizontal sliding friction, and on the other hand, the spring force helps the current collector adjustment bracket 5 maintain a stable sliding posture and avoid shaking. When the current collector adjustment bracket 5 slides to the target position, tighten the positioning bolt 9 so that its end presses against the inner wall of the sliding hole of the current collector cover 1, and fix the current collector adjustment bracket 5 relative to the slide rail 44 and the current collector cover 1, thus completing the position locking.
[0019] The brush 6 is engaged with the buckle 27 via an internal slot. The connecting bracket 24 fixed at the top of the buckle 27 is fixedly connected to the compression spring 26 at the bottom of the mounting bracket 23. When the brush 6 wears out due to long-term use, or when there is a slight deviation in the position of the sliding contact line, the compression spring 26 will generate a compensating force through its own elastic expansion and contraction, pushing the connecting bracket 24 to drive the buckle 27 and the brush 6 to move synchronously, ensuring that the brush 6 is always in close contact with the sliding contact line. The first limiting rod 25 fixed at the bottom of the mounting bracket 23 passes through the sliding hole of the connecting bracket 24. When the connecting bracket 24 moves, it will slide along the first limiting rod 25 to prevent the connecting bracket 24 from deviating. At the same time, the limiting bolt 21 connected to the connecting bracket 24 through the internal threaded hole passes through the sliding hole of the wear-resistant frame 22 and the sliding hole of the mounting bracket 23. When the connecting bracket 24 drives the limiting bolt 21 to slide, the wear-resistant frame 22 can reduce the frictional wear between the limiting bolt 21 and the mounting bracket 23, and the two ends of the limiting bolt 21 will be limited by the sliding hole to prevent the connecting bracket 24 from sliding excessively and causing damage to the compression spring 26.
