Description

Technical Field

[0001] The present application relates to the technical field of power facilities, and in particular to an anti-fall intelligent bus duct. Background Art

[0002] Busbar ducts are busbar systems consisting of a metal (steel or aluminum) protective casing, conductive bars, insulation materials, and related accessories. They are used to distribute high power to various components in a distributed system and are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects.

[0003] Bus ducts are typically installed high up in the room to avoid pedestrians and other equipment. However, during installation or use, bus ducts can fall from heights, posing a safety hazard to pedestrians and equipment below. Therefore, safety features are required.

[0004] In the related art, the intelligent bus duct includes a bus duct body and an anti-falling device fixedly installed on the side of the bus duct body, the anti-falling device includes a clamping plate and a mounting block fixedly installed on the side of the bus duct body, a receiving groove is provided on the side of the mounting block close to the bus duct body, a rotating shaft is connected to the vertical axis in the receiving groove, a connecting wire is wound around the rotating shaft, the end of the connecting wire is fixedly connected to the bus duct body, the end of the rotating shaft extends to the outside of the mounting block away from the bus duct body, guide columns are symmetrically provided on the mounting block, sliding plates are slidably provided on the inner sides of the guide columns, the clamping plates are fixedly provided on the ends of the corresponding sliding plates, gears are fixedly provided on the ends of the rotating shaft, tooth grooves are provided on the inner sides of the sliding plates, the sliding plates are meshed with gears, and an installation mechanism for fixedly installing the mounting block is also fixedly provided on the mounting block.

[0005] The aforementioned anti-fall device utilizes the falling busbar body to drive the gears, which then drive the two sliding plates up and down. The clamping plates then clamp the falling busbar body, preventing it from falling. However, the two sliding plates and the clamping plates are offset vertically and spaced far apart, resulting in a loose clamping structure and poor stability, resulting in an unsatisfactory anti-fall effect. Summary of the Invention

[0006] The purpose of this application is to provide an anti-fall intelligent bus duct, which can make the intelligent bus duct more stable to install and have a better anti-fall effect.

[0011] The elastic locking mechanism is in a stretched state and is connected between the upper clamping wheel and the lower clamping wheel.

[0012] When the upper and lower clamping wheels are engaged, the upper and lower clamping wheels are engaged with the upper and lower clamping wheels, and the upper and lower clamping wheels are engaged with the lower and lower clamping wheels, respectively.

[0013] Optionally, the connecting frame includes a fixed seat, two parallel pull rods connected to the fixed seat, an upper wheel seat slidably connected to the two pull rods, and a lower wheel seat detachably connected to the lower ends of the two pull rods, the upper clamping wheel is rotatably connected to the upper wheel seat, and the lower clamping wheel is rotatably connected to the lower wheel seat.

[0014] By adopting the above technical solution, the support assembly is connected to the installation base through the fixed seat, the upper wheel seat and the lower wheel seat are installed on two pull rods, the upper clamping wheel is connected to the upper wheel seat, and the lower clamping wheel is connected to the lower wheel seat. The upper clamping wheel will move up and down on the pull rod driven by the upper wheel seat to clamp the bus duct body, and the lower clamping wheel will adjust the installation height on the pull rod driven by the lower wheel seat, thereby controlling the installation height of the bus duct body.

[0015] Optionally, the upper clamping wheel is arranged on the side of the upper wheel seat facing the bus duct body, and an upper connecting plate is provided on the side of the upper wheel seat facing away from the bus duct body, and the pull rod vertically passes through the upper connecting plate.

[0017] Optionally, the lower clamping wheel is arranged on the side of the lower wheel seat facing the bus duct body, and a lower connecting plate is provided on the side of the lower wheel seat facing away from the bus duct body. The pull rod vertically passes through the lower connecting plate, and two locking nuts are threadedly connected to the pull rod, and the locking nuts abut against the upper and lower sides of the lower connecting plate.

[0018] By adopting the above technical solution, the height of the lower wheel seat on the pull rod is adjusted by two locking nuts, and then the height of the lower clamping wheel on the pull rod is adjusted to achieve control of the installation height of the bus duct body.

[0022] By adopting the above technical solution, the two ends of the slot are set to inclined slopes. When the upper clamping wheel and the lower clamping wheel enter the slot, they can slide down along the slope to avoid the sudden drop in height of the upper clamping wheel and the lower clamping wheel, which may cause a large vibration of the bus duct body, thereby protecting the bus duct body and the internal structure; when installing the bus duct, starting from one end of the bus duct body, the two support components can be gradually passed through, and the bus duct body can slide along the two sets of clamping wheels. The clamping wheels can slide in and out through the slope of the slot to avoid the bus duct body being stuck by the two sets of clamping wheels, thereby reducing the difficulty of moving the bus duct body.

[0024] By adopting the above technical solution, the elastic member applies a force to the upper wheel seat and the lower wheel seat to move closer to each other, so that the upper clamping wheel and the lower clamping wheel clamp the bus duct body more tightly, and the bus duct body is installed more firmly.

[0025] Optionally, a movable groove is provided on the upper wheel seat and / or the lower wheel seat in the up and down directions, and a plurality of limit slots are provided on the side walls of the movable groove. The upper connecting rod and / or the lower connecting rod are slidably set in the corresponding movable groove and are snapped into the limit slots.

[0026] By adopting the above technical solution, movable grooves and limit slots are set on the upper wheel seat and the lower wheel seat, which can adjust the connection position of the elastic member on the upper wheel seat and the lower wheel seat, and then adjust the initial position of the two ends of the elastic member, so that the elastic member can have sufficient elastic deformation to meet the installation requirements of bus ducts of different sizes, while maintaining a sufficiently large elastic force to clamp the bus duct body.

[0027] Optionally, both ends of the upper connecting rod and the lower connecting rod are connected with anti-drop caps, and the anti-drop caps abut against two side surfaces of the upper wheel seat and the lower wheel seat.

[0028] By adopting the above technical solution, anti-drop caps are provided at both ends of the upper connecting rod and the lower connecting rod, which can prevent the two connecting rods from being separated from the two wheel seats, making the state of the entire elastic locking mechanism more stable.

[0029] Optionally, the upper connecting rods on the two groups of support assemblies are arranged opposite to each other and the lower connecting rods are arranged opposite to each other, and synchronization rods are connected between the upper connecting rods and the lower connecting rods.

[0030] By adopting the above technical solution, when moving the positions of the upper connecting rod and the lower connecting rod, the two relative connecting rods can be moved synchronously, which makes adjustment more convenient.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0042] This application proposes an anti-fall intelligent bus duct, referring to Figure 1 and 2 , including a bus duct body 1, a supporting mechanism 2 and an elastic locking mechanism 3. The supporting mechanism 2 includes two groups of supporting components, which are respectively supported on the left and right sides of the bus duct body 1. The bus duct body 1 is installed on a fixed foundation. The elastic locking mechanism 3 is provided in multiple groups and is respectively installed on the two groups of supporting components to provide elastic force for the supporting components, press and fix the bus duct body 1 on the supporting components, and prevent the bus duct body from falling off and falling.

[0043] The bus duct body includes a box body and a copper busbar disposed therein, with multiple terminals at both ends. A top plate 11 is disposed at the top and a bottom plate 12 is disposed at the bottom. Baffles 13 are disposed on both sides of the top and bottom plates 11, 12, facing away from each other. Baffles 13 are disposed along the length of the top and bottom plates 11, 12, and the baffles 13 on the same plate body are parallel. Slots 14 are disposed on the top and bottom plates 11, 12, located inside and adjacent to the baffles 13. Slots 14 are disposed on the side plates of the box body, and their lengths are parallel to those of the baffles 13. Two slots 14 are disposed on each side of the baffle 13, with a gap between them. The slots 14 on the top and bottom plates 11, 12 are positioned vertically opposite each other, with their openings facing away from each other. The slots 14 include a flat bottom and inclined slopes at both ends of the length. The width of the slots 14 gradually increases from the bottom to the opening, forming an expanded slot.

[0044] Reference Figure 1 and 3 The support mechanism 2 is connected to the middle section of the bus duct body 1, and the two groups of support components are symmetrically arranged on the left and right sides of the bus duct body 1. The support components include a connecting frame, an upper clamping wheel 21 and a lower clamping wheel 22. The connecting frame includes a fixed seat 23, two pull rods 24, an upper wheel seat 25 and a lower wheel seat 26.

[0045] The fixing seat 23 is configured as a rectangular metal plate, which is fixed to a fixed foundation by expansion screws. Two pull rods 24 are welded to the two ends of the fixing seat 23 perpendicular to the lower surface of the fixing seat 23. In this embodiment, the pull rod 24 is configured as a round rod with a smooth rod at the upper end and a lead screw at the lower end. An upper connecting plate is provided on the side of the upper wheel seat away from the bus duct body, and the pull rod passes through the upper connecting plate vertically. The upper wheel seat 25 is configured as a rectangular plate, which is provided on the outside of the top plate 11. Two upper connecting plates 251 are fixedly connected to the two ends of the side of the upper wheel seat 25 away from the bus duct body 1. A circular hole is provided on the upper connecting plate 251 that passes through the upper and lower parts. The pull rod 24 passes through the circular hole and passes through the upper connecting plate 251 vertically, so that the upper wheel seat 25 can slide up and down on the two pull rods 24. The structure of the lower wheel seat 26 is the same as that of the upper wheel seat 25. The lower wheel seat 26 is arranged on the outside of the base plate 12. The two ends of the side of the lower wheel seat 26 facing away from the bus duct body 1 are fixedly connected to two lower connecting plates 261. The pull rod 24 vertically passes through the lower connecting plate 261. The lower end of each pull rod 24 is threadedly connected to two locking nuts 27. The two locking nuts 27 are respectively abutted against the upper and lower sides of the lower connecting plate 261 to adjust and fix the position of the lower wheel seat 26.

[0046] The upper clamping wheel 21 and the lower clamping wheel 22 have the same structure and are symmetrically arranged up and down. The upper clamping wheel 21 is arranged on the side of the upper wheel seat 25 facing the bus duct body 1, and the lower clamping wheel 22 is arranged on the side of the lower wheel seat 26 facing the bus duct body 1. The upper clamping wheel 21 abuts on the top plate 11, and the lower clamping wheel 22 abuts on the bottom plate 12. The upper clamping wheel 21 and the lower clamping wheel 22 are both provided with card slots 14 in the front and rear directions, so that the upper clamping wheel 21 and the lower clamping wheel 22 can fall into the card slot 14 when moving forward or backward. Taking the above clamping wheel 21 as an example, the upper clamping wheel 21 includes a triangular rotating block 211 and two rotating wheels 212. A top corner position of the triangular rotating block 211 is connected to a rotating shaft and is rotatably connected to the upper wheel seat 25 through the rotating shaft. The other two top corner positions of the triangular rotating block 211 are respectively rotatably connected to a rotating wheel 212. Both rotating wheels 212 are in contact with the top plate 11, and the sides of the rotating wheels 212 are guided by the baffle 13 to prevent the bus duct body 1 from swinging horizontally. The upper clamping wheel 21 and the lower clamping wheel 22 each use two rotating wheels 212 to abut against the bus duct body 1, which can increase the support points for the bus duct body 1 and make the installation of the bus duct body 1 more stable.

[0047] Reference Figure 1 and 4 The elastic locking mechanism 3 is connected between the upper wheel seat 25 and the lower wheel seat 26 and is always in a stretched state, used to pull the upper wheel seat 25 toward the lower wheel seat 26 to clamp the bus duct body 1. The elastic locking mechanism 3 includes an upper connecting rod 31, a lower connecting rod 32 and an elastic member 33. The upper connecting rod 31 is connected to the upper wheel seat 25 and passes through both sides of the upper wheel seat 25. The lower connecting rod 32 is connected to the lower wheel seat 26 and also passes through both sides of the lower wheel seat 26. In this embodiment, the upper connecting rod 31 and the lower connecting rod 32 are positioned relative to each other. The elastic member 33 is connected between the upper connecting rod 31 and the lower connecting rod 32, which are relative to each other. In this embodiment, the elastic member 33 is a tension spring, which is always in a stretched state. One elastic member 33 is provided at each end of the upper clamping wheel 21 in the direction of travel, so that the tension received by both sides of the upper clamping wheel 21 and the lower clamping wheel 22 is balanced.

[0048] In this embodiment, the spacing between the upper connecting rod 31 and the lower connecting rod 32 is adjustable. The upper connecting rod 31 can be fixed and the lower connecting rod 32 can be movable. In this case, the lower wheel seat 26 is provided with a movable groove 28 in the vertical direction. The upper connecting rod 31 can be movable and the lower connecting rod 32 can be fixed. In this case, the upper wheel seat 25 is provided with a movable groove 28 in the vertical direction. Alternatively, both the upper connecting rod 31 and the lower connecting rod 32 can be movable, and both the upper wheel seat 25 and the lower wheel seat 26 are provided with movable grooves 28 in the vertical direction. In this embodiment, a plurality of limit slots 29 are provided on one side wall of the movable groove 28. The upper connecting rod 31 and the lower connecting rod 32 are cylindrical rods that can slide along the movable groove 28 and move into different limit slots 29. When they are locked into the limit slots 29, the initial positions of the two ends of the elastic member 33 are adjusted, so that the elastic member 33 can have sufficient elastic deformation.

[0049] Reference Figure 3 and 4 , anti-drop caps 34 are connected to both ends of the upper connecting rod 31 and the lower connecting rod 32. In this embodiment, the anti-drop caps 34 are circular plates with a diameter greater than the width of the movable groove 28 and the limit slot 29 to prevent the upper connecting rod 31 and the lower connecting rod 32 from falling. The anti-drop caps 34 abut against the two side surfaces of the upper wheel seat 25 and the lower wheel seat 26 to prevent the upper connecting rod 31 from axially moving from the upper wheel seat 25 and the lower connecting rod 32 from axially moving on the lower wheel seat 26.

[0050] The upper connecting rods 31 installed on the two groups of support assemblies are arranged opposite to each other, and the lower connecting rods 32 are also arranged opposite to each other. A synchronization rod 35 is connected between the two upper connecting rods 31 arranged opposite to each other, and a synchronization rod 35 is also connected between the two lower connecting rods 32 arranged opposite to each other. In this embodiment, the two ends of the synchronization rod 35 are correspondingly connected to the anti-detachment caps 34 of the two upper connecting rods 31 or to the anti-detachment caps 34 of the two lower connecting rods 32, so that the two relative connecting rods can be moved synchronously, which is more convenient when adjusting the height of the connecting rods.

[0051] The implementation principle of the embodiment of this application is:

[0052] The two sides of the bus duct body 1 are supported by two groups of supporting components. The upper clamping wheel 21 and the lower clamping wheel 22 clamp the bus duct body 1 in the middle, and the upper and lower directions of the bus duct body 1 are limited and supported. Then, the elastic member 33 in the stretched state is used to provide pressure to clamp the bus duct body 11. When the bus duct body 1 falls downward, it will be pulled by the elastic member 33 and then continue to be clamped by the upper clamping wheel 21 and the lower clamping wheel 22, thereby improving the safety of preventing falling. When the upper clamping wheel 21 and the lower clamping wheel 22 move, the upper clamping wheel 21 rolls on the top plate 11, and the lower clamping wheel 22 rolls on the bottom plate 12, and both fall into the slot 14. The distance between the upper clamping wheel 21 and the lower clamping wheel 22 is reduced. Under the pulling force of the elastic member 33, the bus duct body 1 continues to be clamped by the upper clamping wheel 21 and the lower clamping wheel 22 and will not fall. At the same time, the upper clamping wheel 21 and the lower clamping wheel 22 are stuck in the slot 14, so that the bus duct body 1 will not continue to slide, thereby avoiding falling.

[0053] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
