Description

Technical Field

[0001] This invention relates to the field of aging safety testing devices, specifically to an aging safety testing device for fire protection facilities. Background Technology

[0002] Common fire-fighting equipment includes fire hoses and flexible hoses used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and are covered with woven linen on the outer surface. In the past, the aging detection of fire hoses was done by random sampling to observe for damage and aging. However, fire hoses are usually shrunken, and small aging damage is difficult to detect because the hose is not stretched. There is a lack of a device that can detect the aging and scratches of the inner and outer linings of fire hoses, especially when stretched, to check whether the fabric on the hose has broken due to aging, thus avoiding the danger of the fire hose being suddenly squeezed and burst by water pressure during use. Therefore, we propose a safety detection device for the aging of fire-fighting equipment to solve the above problems. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figure 1-6As shown, the present invention provides a safety testing device for aging of fire protection facilities, including a base 1. Two first guide rails 12 and a second guide rail 13 are fixedly installed on the upper surface of the base 1. A mounting seat 2 is slidably installed in the first guide rail 12. A clamping assembly 5 is slidably connected to the upper surface of the mounting seat 2. A driving assembly 3, a reciprocating assembly 4, and a damage detection device 6 are fixedly connected to the mounting seat 2. The driving assembly 3 is drively connected to the reciprocating assembly 4 and the damage detection device 6. A moving assembly 9 is drively connected to the driving assembly 3. The moving assembly 9 is slidably connected to the clamping assembly 5. The reciprocating assembly 4 and the clamping assembly 5 are slidably engaged. A fire hose 7 is installed inside the damage detection device 6. The clamping assembly 5 is attached to the outer surface of the fire hose 7. An expanding assembly 8 is installed inside the fire hose 7. The expanding assembly 8 is magnetically connected to the damage detection device 6. The expanding assembly 8 expands the inner wall of the fire hose 7, and the cross-section of the fire hose 7 is detected for damage when it is expanded. Then, the driving assembly 3 works in conjunction with the clamping assembly 5 and the damage detection device 6 to detect the surface damage of the fire hose 7 when it is being pulled during the movement of the fire hose 7.

[0026] Furthermore, a caster wheel 11 is fixedly installed on the bottom surface of the base 1, and a guide roller 14 is slidably connected inside the second guide rail 13. The outer surface of the guide roller 14 is attached to the outer surface of the fire hose 7, so that the base 1 can be moved easily and the fire hose 7 can be guided by the guide roller 14.

[0027] Furthermore, the upper surface of the mounting base 2 is fixedly provided with a mounting plate 22, a first upright plate 23 and a second upright plate 24. The upper surface of the mounting base 2 is provided with two first convex sliding grooves 21. The clamping assembly 5 is slidably connected in the first convex sliding grooves 21. The side of the mounting plate 22 is fixedly connected with a damage detection device 6. The outside of the first upright plate 23 is fixedly connected with a driving assembly 3. The side surface of the second upright plate 24 is provided with a rectangular groove 241. The side surface of the second upright plate 24 is fixedly connected with a reciprocating assembly 4. Thus, the mounting base 2 enables the fire hose 7 to be detected stably.

[0028] Furthermore, the drive assembly 3 includes a motor 31, which is fixedly installed on the outside of the first upright plate 23. The output end of the motor 31 movably passes through the first upright plate 23 and is fixedly connected to a first half-face gear 33 and a pulley at the upper end of the first belt mechanism 32. The pulley at the bottom end of the first belt mechanism 32 is driven to connect to a moving assembly 9. The output end of the motor 31 is driven to connect to a damage detection device 6. The first half-face gear 33 is meshed with a first toothed plate 34. The two ends of the first toothed plate 34 are slidably connected to first guide blocks 35. The first toothed plate 34 is driven to connect to a reciprocating assembly 4, thereby the motor 31 drives the half-face gear 33 and the first belt mechanism 32 to rotate, and the first half-face gear 33 causes the first toothed plate 34 to slide back and forth.

[0029] Furthermore, the reciprocating assembly 4 includes a horizontal plate 41, with a first guide block 35 fixedly connected to the side of the horizontal plate 41, so that the first toothed plate 34 can slide stably along the first guide block 35. One end of the horizontal plate 41 is fixedly connected to the side surface of the second vertical plate 24. A guide groove 411 is provided in the horizontal plate 41, and a convex slide plate 42 is slidably connected in the guide groove 411. The first toothed plate 34 is fixedly connected to the side of the convex slide plate 42, and a toothed groove 421 is provided on the upper surface of the convex slide plate 42. A power gear 43 is meshed with the toothed groove 421. The power gear 43 is rotatably mounted on the horizontal plate 41 and can rotate stably. The power gear 43 is driven by a first gear 44, and the first gear 44 meshes with two first racks 45. The first racks 45 are slidably connected to the clamping assembly 5, so that the toothed groove 421 of the convex slide plate 42 drives the power gear 43 to rotate, and the two first gears 44 drive the two first racks 45 to move.

[0030] Furthermore, the power gear 43 is provided with two flat teeth 431. The end faces of the flat teeth 431 are attached to the upper surface of the convex slide plate 42. Thus, when the tooth groove 421 causes the power gear 43 to rotate, the end faces of the flat teeth 431 are attached to the upper surface of the convex slide plate 42, so that the power gear 43 will not rotate with inertia and the first tooth plate 34 will not continue to rotate.

[0031] Furthermore, the clamping assembly 5 includes two columns 51. A convex block 54 is fixedly connected to the bottom end of each column 51. The convex block 54 is slidably disposed in a first convex groove 21. A spring 55 is fixedly connected to one end of the convex block 54. One end of the spring 55 is fixedly connected to the inner wall of the first convex groove 21. A cross groove 511 is formed in the column 51. Two pressure strips 52 are slidably connected in the cross groove 511. Anti-slip grooves 521 are formed on the pressure strips 52. Fixing plates 56 are fixedly connected to the sides of the two columns 51. A moving assembly 9 is slidably connected in the fixing plates 56. A guide plate 53 is fixedly provided at one end of each pressure strip 52. A second convex groove 531 is formed in each guide plate 53. A first rack 45 is slidably engaged in the second convex groove 531. Thus, the two first racks 45 cause the two pressure strips 52 to slide in the opposite direction along the column 51, thereby clamping and fixing the fire hose 7.

[0032] Furthermore, the moving component 9 includes a second half-face gear 91, which is connected to the pulley at the bottom of the first belt mechanism 32. The second half-face gear 91 is meshed with a second toothed plate 92. The two ends of the second toothed plate 92 are slidably connected to second guide blocks 93. The second guide blocks 93 are fixedly installed on the inner wall of the first upright plate 23. A push rod 94 is fixedly connected to the inner side of the second half-face gear 91. One end of the push rod 94 is fixedly connected to a fixed shaft 95. The fixed shaft 95 movably passes through the fixed plate 56. Two retaining rings 951 are fixedly provided on the outside of the fixed shaft 95. The two retaining rings 951 are respectively provided on both sides of the fixed plate 56. Thus, the motor 31 drives the second half-face gear 91 to rotate through the first belt mechanism 32, and causes the second toothed plate 92 to slide back and forth along the second guide block 93. The push rod 94 drives the two retaining rings 951 on the fixed shaft 95 to drive the fixed plate 56 and the two uprights 51 to slide back and forth along the first convex groove 21.

[0033] Furthermore, the damage detection device 6 includes a second belt mechanism 61. One end of the second belt mechanism 61 is connected to the output end of the motor 31 via a pulley. The other end of the second belt mechanism 61 is connected to a first bevel gear set 62 and a second bevel gear set 63 via a pulley. The second bevel gear set 63 is connected to a second gear 64 via a gear. The second gear 64 is meshed with a rotary table 65. The inner ring of the rotary table 65 is fixedly connected to a mounting plate 22. The gear ring of the rotary table 65 is fixedly connected to a camera device 67. Multiple arc-shaped magnetic blocks 66 are fixedly connected to the inner wall of the rotary table 65. The arc-shaped magnetic blocks 66 are magnetically connected to the spreading assembly 8. Thus, the second belt mechanism 61 is driven to rotate by the motor 31, which in turn drives the second gear 64 to rotate. This causes the gear ring of the rotary table 65 to drive the camera device 67 to rotate along the outer ring of the fire hose 7, thereby detecting the damage. At the same time, the multiple arc-shaped magnetic blocks 66 are magnetically connected to the spreading assembly 8, allowing the fire hose 7 to be fixedly clamped.

[0034] Furthermore, the spreading assembly 8 includes a first disc 81 and a second disc 82. Multiple pull rods 83 are rotatably hinged to the outer surfaces of both the first disc 81 and the second disc 82. A cylindrical magnetic block 84 is rotatably hinged to the upper end of each pull rod 83. The outer surface of the cylindrical magnetic block 84 is in contact with the inner wall of the fire hose 7. The cylindrical magnetic block 84 is magnetically connected to an arc-shaped magnetic block 66. A threaded sleeve 85 is rotatably engaged inside the second disc 82. A lead screw 86 is fixedly installed on the inner wall of the first disc 81. One end of the lead screw 86 is threaded into the threaded sleeve 85. Thus, by manually adjusting the threaded sleeve 85, the lead screw 86 moves the first disc 81 towards the second disc 82, thereby changing the included angle of the pull rods 83 and enabling the multiple cylindrical magnetic blocks 84 to spread the fire hose 7.

[0035] Working principle: By manually adjusting the screw sleeve 85, the lead screw 86 drives the first disc 81 to move towards the second disc 82. This changes the included angle of the pull rod 83, allowing multiple cylindrical magnetic blocks 84 to expand the fire hose 7 and detect any damage to the cross-section of the fire hose 7. Simultaneously, multiple arc-shaped magnetic blocks 66 are magnetically connected to the expanding assembly 8, securing the fire hose 7 in place. Then, the motor 31 drives the half-face gear 33 and the first belt mechanism 32 to rotate. The rotation of the first half-face gear 33 causes the first toothed plate 34 to slide. This causes the convex sliding plate 42 to slide, which in turn causes the toothed groove 421 to drive the power gear 43 to rotate, and drives the two first racks 45 to move in the opposite direction. Subsequently, the guide plate 53 drives the two pressure strips 52 to slide in the opposite direction, thereby clamping and fixing the fire hose 7. When the toothed groove 421 causes the power gear 43 to rotate, the end face of the flat tooth 431 is in contact with the upper surface of the convex sliding plate 42, so that the power gear 43 will not rotate due to inertia. As a result, the first toothed plate 34 will not continue to rotate, and the two pressure strips 52 can stably clamp and fix the fire hose 7. Then, the motor 31 continues to rotate, and through the first belt mechanism 32, it drives the second half-face gear 91 to rotate, causing the second toothed plate 92 to slide along the second guide block 93. Through the push rod 94, it drives the two retaining rings 951 on the fixed shaft 95 to drive the fixed plate 56 and the two columns 51 to slide a distance in the first convex groove 21. At this time, the column 51 drives the guide plate 53 to slide along the first rack 45 through the pressure strip 52, so that the fire hose 7 can be moved smoothly and the fire hose 7 can be detected to be aged and damaged when it is pulled. Then, the motor 31 continues to rotate, and through the first toothed plate 34 and the second toothed plate 92, it can slide back and forth, so that the fire hose 7 can be moved a distance after being clamped, and then the clamping is released. Then the two columns 51 are reset, realizing the reciprocating cycle. In addition, the motor 31 drives the second belt mechanism 61 to rotate, and drives the second gear 64 to rotate continuously, so that the gear ring of the rotary table 65 drives the camera device 67 to rotate along the outer ring of the fire hose 7, so that the surface of the fire hose 7 can be fully detected for damage.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
