Between the rear guide sleeve 18 and the front guide sleeve 8, there is an intermediate connecting rod 19. Between the two rear guide sleeves 18, there is a rear connecting rod 20 (omitted in the figure).
[0030] Above the front connecting rod 9, there is a gravity balance regulator 21. The gravity balance regulator 21 includes an inner shaft 22 fixed between the two front guide columns 7. On the inner shaft 22, there is a sleeve 23. Between the sleeve 23 and the inner shaft 22, there is a spiral torsion spring 24. The torsion spring 24 is in a stretched state and has a tensile stress. On the sleeve 23, there is a rope pulley 25. On the rope pulley 25, there is a rope 26 connecting the front connecting rod 9.
[0031] One end of the sleeve 23 is provided with a first collar 27 rotatably connected to the inner shaft 22. The other end of the sleeve 23 is provided with a second collar 28 rotatably connected to the inner shaft 22. On the outer side end of the second collar 28, there is a flange 29 extending radially outward. The flange 29 fits the end face of the sleeve 23. On the flange 29, there are multiple circumferentially evenly distributed protrusions 30. On the end face of the sleeve 23, there are grooves 31 cooperating with the protrusions 30. One end of the torsion spring 24 is fixed to the inner shaft 22, and the other end of the torsion spring 24 is fixed to the second collar 28.
[0032] There are two rope pulleys 25, and the two rope pulleys 25 are respectively located above the two front guide sleeves 8.
[0033] A plurality of rollers 32 are provided on the top of the moving frame 3. The rollers 32 are connected to the cabinet body 1 through a track 33. A baffle 34 is provided at the front end of the track 33. The baffle 34 is used to limit the extreme outward movement position of the moving frame 3. The rollers 32 and the track 33 can also be replaced by linear sliders and linear slide rails.
[0034] Limit plates 36 for preventing detachment are provided at the bottoms of the front side guide post 7 and the rear side guide post 17.
[0035] The rotation axis of the swing door 2 and the inner side wall of the swing door 2 are in the same plane.
[0036] Usage method of the five-point seat belt storage cabinet: Arrange and hang a plurality of five-point seat belts on two hanging arms 4 for storage. The hanging arms 4 correspondingly pass through the holes in the seat belts through which the arms pass, that is, Figure 6 at point A in
[0037] When taking out the seat belt, open the swing door 2 to 180°. The swing door 2 drives the moving frame 3 to move outward through the traction cable 5. The moving frame 3 drives the hanging arms 4 to move outward, so that the seat belt is located outside the cabinet body 1. When the swing door 2 is opened to 180°, a part of the traction cable 5 fits against the inner side wall of the swing door 2 and passes through the rotation axis of the swing door 2. At this time, although the tension spring 6 gives the swing door 2 a traction force through the traction cable 5, since the force arm of the traction force is zero, the traction force cannot be converted into a torque for rotating the swing door 2, and the swing door 2 remains stationary. At this time, the worker can wear the seat belt outside the cabinet and between the two hanging arms 4. After wearing it, the worker can leave. Subsequently, the worker can continue to wear the seat belts still remaining on the two hanging arms 4.
[0038] After the taking-out is completed, gently pull the swing door 2. Under the traction force of the tension spring 6, the swing door 2 automatically closes.
[0039] For workers of different heights, it may be necessary to adjust the height of the seat belt when wearing the seat belt. The adjustment method is to rotate the height adjustment rod 12 and snap the height adjustment rod 12 into the corresponding card slot 11. The height change of the height adjustment rod 12 is transmitted to the moving frame 3 through the steel cable 14, so that the height of the moving frame 3 changes, and thus the height of the seat belt on the hanging arms 4 changes. When the height of the height adjustment rod 12 rises, the height of the seat belt drops. On the contrary, when the height of the height adjustment rod 12 drops, the height of the seat belt rises.
[0040] The single weight of the safety belts equipped and used in the hydropower plant is generally above 1.5 kg, and at least 10 safety belts need to be placed on one cabinet body 1, resulting in a load on the suspension arm 4 of at least 15 kg. The relatively large load makes it difficult to adjust the lifting of the height adjustment rod 12. Therefore, a gravity balance adjuster 21 is used to balance the gravity and reduce the resistance of the height adjustment rod 12 during lifting and lowering. The principle is that the torsion spring 24 provides torque to the sleeve 23, and the sleeve 23 transmits the torque to the rope pulley 25. The rope pulley 25 provides an upward pulling force to the front side connecting rod 9 through the rope 26 to offset part of the gravity load of the safety belts on the suspension arm 4. Different numbers of safety belts may be stored in different cabinet bodies 1. By axially pulling out the flange 29 and rotating the flange 29, the pre-tightening force of the torsion spring 24 is increased or decreased. After the adjustment is completed, the protrusion 30 on the flange 29 is inserted back into the groove 31 to adapt to different gravity loads, making the application range of the present utility model wider.
