Abstract
Description
Technical Field
[0001] This application relates to the technical field of aerial work, and in particular, to an orbital diverter. Background Art
[0002] The orbital diverter, as an indispensable auxiliary component of the anti-falling device system, with its innovative structural design and precise control logic, has successfully achieved the flexible switching and scheduling of the anti-falling device in a complex multi-dimensional orbital network. In high-risk scenarios such as aerial work and vertical transportation, when the anti-falling device needs to smoothly transition from the main track to the vertical secondary track, the orbital diverter plays a crucial role, ensuring a seamless connection in this process, maintaining the continuity of operation, and defending the core function of the anti-falling device as a safety barrier.
[0003] In the related art, the orbital diverter generally includes a first track, a second track, and an outer turntable. The first track and the second track are vertically fixed on the outer periphery of the outer turntable, and an inner turntable is arranged inside the outer turntable. The inner turntable is movably connected to the outer turntable. A rotating track is fixedly arranged on the inner turntable. A rotating shaft is fixedly connected to the middle of the inner turntable through a screw. The rotating shaft passes through the outer turntable, and the outer turntable is connected to the rotating shaft through a bearing; the user can adjust the angle of the rotating track to make it coincide with the first track or the second track.
[0004] However, this design faces a key challenge in actual operation: that is, when manually adjusting the inner turntable, it is difficult to ensure that each time the rotating track can be accurately placed in a position completely perpendicular to the first track or the second track. Once the angle deviates slightly, the anti-falling device running on the rotating track may accidentally disengage due to discontinuous paths, which undoubtedly poses a potential safety hazard that cannot be ignored for the entire system and there is room for improvement. Utility Model Content
[0005] The purpose of this application is to provide an orbital diverter to solve the problem that the anti-falling device on the rotating track may accidentally disengage due to discontinuous paths in the above-mentioned related art.
[0006] An orbital diverter provided by this application adopts the following technical solutions:
[0007] An orbital diverter includes an outer turntable, two first tracks, and two second tracks. The two first tracks are symmetrically fixed on the outer periphery of the outer turntable, and the two second tracks are symmetrically fixed on the outer periphery of the outer turntable. The length directions of the first track and the second track are perpendicular; an adjustment track is rotatably arranged inside the outer turntable, and both ends of the adjustment track can rotate to a position where they abut against the inner ends of the first track and the second track; a limiting card strip is fixedly arranged on the outer peripheral edge of the outer turntable between the first track and the second track, and both ends of the adjustment track can abut against the inner wall of the limiting card strip.
[0008] By adopting the above technical solution, due to the arrangement of the limit clamping strip, when the adjusting track rotates to the position between the first track and the second track, both ends of the adjusting track can abut against the inner wall of the limit clamping strip, thereby preventing the anti-falling device on the adjusting track from coming out and reducing the corresponding potential safety hazards.
[0009] Optionally, baffles are symmetrically and fixedly arranged on opposite side surfaces of the adjusting track; when one end of the first track or the second track abuts against the end of the adjusting track, the baffle limits the inner end of the other.
[0010] By adopting the above technical solution, due to the installation of the baffle, when one end of the first track or the second track abuts against the end of the adjusting track, the baffle limits the inner end of the other, thereby reducing the possibility of the anti-falling device slipping out from the inner end of the first track or the second track and improving the corresponding safety performance.
[0011] Optionally, limit blocks capable of abutting against the side surface of the adjusting track are symmetrically and fixedly arranged on the inner wall of the outer turntable, and the limit blocks are used to limit the rotation range of the adjusting track.
[0012] By adopting the above technical solution, due to the application of the limit blocks, the rotation range of the adjusting track is limited, and at the extreme positions of rotation, they respectively abut against the inner ends of the first track and the second track, thereby improving the service performance of the track diverter during application.
[0013] Optionally, a locking nut, a locking bolt, and a rotating sleeve sleeved on the outer periphery of the locking bolt are arranged on the side surface of the outer turntable. A first through hole is formed on the outer turntable, and an installation cavity is formed on the adjusting track. A second through hole coaxial with and communicating with the first through hole is formed on the installation cavity; the locking bolt passes through the first through hole and the second through hole and is tightly locked by the locking nut in the installation cavity, and the outer periphery of the rotating sleeve abuts against the inner walls of the first through hole and the second through hole.
[0014] By adopting the above technical solution, when the adjusting track is rotatably arranged in the inner cavity of the outer turntable, the rotating sleeve is sleeved on the outer periphery of the locking nut in advance, then the locking bolt passes through the first through hole and the second through hole, and is tightly locked by the locking nut in the installation cavity. At this time, the outer periphery of the rotating sleeve abuts against the inner walls of the first through hole and the second through hole, thereby realizing the rotational connection between the adjusting track and the outer turntable.
[0015] Optionally, a relief sunk groove is formed on the side surface of the outer turntable away from the adjusting track.
[0016] By adopting the above technical solution, the raw materials required for producing the outer turntable are saved, and the production cost is reduced.
[0017] Optionally, a plurality of reinforcing ribs are uniformly distributed on the inner wall of the relief sinking groove of the outer turntable.
[0018] By adopting the above technical solution, the overall structural strength of the outer turntable is improved.
[0019] Optionally, fixing ears are symmetrically fixed on the outer edge of the side of the outer turntable away from the adjustment track, and fixing through holes are formed in the fixing ears.
[0020] By adopting the above technical solution, due to the installation of the fixing ears, it is convenient to fix the outer turntable on the surface to be installed after locking through the fixing through holes, improving the installation stability of the outer turntable.
[0021] Optionally, extension plates are uniformly fixed on the outer periphery of the outer turntable, extension gaps communicating with the inner cavity of the outer turntable are formed in the extension plates, and the first track and the second track are placed in the corresponding extension gaps and fastened by bolts.
[0022] By adopting the above technical solution, due to the arrangement of the extension plates, it is convenient to install and fix the first track and the second track.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Due to the arrangement of the limit clamping strips, when the adjustment track rotates to the position between the first track and the second track, both ends of the adjustment track can abut against the inner wall of the limit clamping strips, thereby preventing the anti-falling device on the adjustment track from coming off and reducing the corresponding safety hazards.

Specific embodiments
[0032] The following further elaborates on the present application in detail with reference to all the attached drawings.
[0033] Embodiment:
[0034] Referring to Figure 1 and Figure 2 , a track steering device includes an outer turntable 1, two first tracks 2, and two second tracks 3. The two first tracks 2 are symmetrically fixed on the outer periphery of the outer turntable 1, the two second tracks 3 are symmetrically fixed on the outer periphery of the outer turntable 1, and an adjusting track 4 is rotatably arranged inside the outer turntable 1;
[0035] After installation, the length directions of the first track 2 and the second track 3 are perpendicular to each other; when the adjusting track 4 rotates relative to the outer turntable 1, both ends of the adjusting track 4 can rotate to a position where they are in contact with the inner ends of the first track 2 and the second track 3.
[0036] Referring to Figure 1 and Figure 2 , on the outer peripheral edge of the outer turntable 1, a limit clamping strip 12 is integrally formed between the first track 2 and the second track 3, that is, the total number of the limit clamping strips 12 is four; when the adjusting track 4 rotates to a position between the first track 2 and the second track 3, both ends of the adjusting track 4 can be in contact with the inner wall of the limit clamping strip 12, so as to prevent the fall arrester on the adjusting track 4 from coming off and reduce the corresponding safety hazards.
[0037] Referring to Figure 3 , on the side of the outer turntable 1, there are a locking nut 5, a locking bolt 6, and a rotating sleeve 7 sleeved on the outer periphery of the locking bolt 6. Among them, a first through hole 11 is opened on the outer turntable 1 along its own axis direction, an installation cavity 41 is opened on the adjusting track 4, and at the same time, a second through hole 42 coaxial with and communicating with the first through hole 11 is opened on the installation cavity 41;
[0038] When the adjusting track 4 is rotationally arranged in the inner cavity of the outer turntable 1, the rotating sleeve 7 is sleeved on the outer periphery of the locking nut 5 in advance, and then the locking bolt 6 passes through the first through hole 11 and the second through hole 42, and is tightly locked by the locking nut 5 in the installation cavity 41. At this time, the outer periphery of the rotating sleeve 7 abuts against the inner walls of the first through hole 11 and the second through hole 42.
[0039] Refer to Figure 3 , on the opposite sides of the adjusting track 4, baffles 43 are symmetrically and fixedly arranged; when one end of either the first track 2 or the second track 3 abuts against the end of the adjusting track 4, the baffle 43 limits the inner end of the other one, reducing the possibility that the fall arrester on the first track 2 or the second track 3 directly disengages from the inner end.
[0040] Refer to Figure 4 , on the inner wall of the outer turntable 1, limit blocks 13 that can abut against the side surface of the adjusting track 4 are symmetrically and fixedly arranged. The limit blocks 13 are used to limit the rotation range of the adjusting track 4, enabling the adjusting track 4 to only rotate freely within a maximum range of ninety degrees. At the limit positions of rotation, it abuts against the inner ends of the first track 2 (see Figure 2 ) and the second track 3 (see Figure 2 ), respectively.
[0041] Refer to Figure 5 , on the side surface of the outer turntable 1 away from the adjusting track 4, a relief sunk groove 14 is provided, and at the same time, a number of reinforcing ribs 141 are evenly distributed on the inner wall of the outer turntable 1 in the relief sunk groove 14; on the premise of ensuring the structural strength of the outer turntable 1, the raw materials required for processing the outer turntable 1 are reduced, and the production cost is reduced.
[0042] Refer to Figure 4 and Figure 5 , four extension plates 15 are evenly and fixedly arranged on the outer periphery of the outer turntable 1. An extension gap 151 communicating with the inner cavity of the outer turntable 1 is provided on the extension plate 15. During the installation process of the first track 2 and the second track 3, the corresponding first track 2 and second track 3 are placed in the corresponding extension gap 151 and fastened by two bolts, thereby realizing the installation and fixation of the first track 2 and the second track 3.
[0043] Refer to Figure 5 , on the outer edge of the side surface of the outer turntable 1 away from the adjusting track 4, fixing ears 16 are symmetrically and fixedly arranged. Fixing through holes 161 are provided on the fixing ears 16, facilitating the fixation of the outer turntable 1 on the surface to be installed by passing through the fixing through holes 161 with a lock, improving the installation stability of the outer turntable 1.
[0044] The implementation principle of the embodiment of this application is as follows:
[0045] When the adjusting track 4 rotates relative to the outer turntable 1, both ends of the adjusting track 4 can rotate to positions where they abut against the inner ends of the first track 2 and the second track 3; when the adjusting track 4 rotates to a position between the first track 2 and the second track 3, both ends of the adjusting track 4 can abut against the inner walls of the limiting clamping strips 12, thereby preventing the falling arrester on the adjusting track 4 from slipping out and reducing corresponding safety hazards.
