Abstract

The wear-resistant device drives water into the pressurizing chamber of the pressurizing device through the water adding device, and the water pressure drives the pressurizing plunger to extend outward. The pressurizing plunger drives the friction clamping assembly to slide downward through the pressurizing connecting rod, and the friction clamping assembly drives the first friction column to press down. At this time, the first friction column and the second friction column will clamp the water outlet belt to simulate the wear when the water outlet belt is pulled out. At the same time, the friction clamping assembly will clamp the side of the water outlet belt during the descent process to realize the friction test of the winding part. The water adding device manually pulls out the transformer assembly, and the transformer assembly gradually opens the three inlets of the water adding shell, so that more water flows into the water adding shell. At this time, multiple streams of water will have different impacts on the pressurizing plunger, thereby realizing the synchronous control of water pressure and pressing force.

Description

Technical Field

[0001] The invention relates to the field of hose wear detection, and in particular to a fire hose wear detection device. Background Art

[0002] When using a fire hose, it is generally necessary to pull out the hose. During the pulling-out process, the hose will produce severe friction with the edge of the fire cabinet or the ground, causing damage to the outer surface of the hose. At the same time, the impact of the fire water on the inside of the hose will cause the hose to leak. Therefore, before the fire hose is put into use, it is necessary to conduct a wear resistance test on the fire hose samples.

[0003] The existing fire hose wear resistance testing equipment generally adopts a combination of a water spray mechanism and a friction mechanism to simultaneously perform wear resistance tests on the inner and outer surfaces of the fire hose; however, it is not possible to control the impact force of the water flow on the inner surface and the friction force of the friction mechanism on the outer surface through a power source; the existing fire hose wear resistance testing equipment is also unable to change the pulling speed of the hose, thereby being unable to simulate the wear of the hose at different pulling speeds; therefore, a fire hose wear resistance testing device is needed that can simultaneously adjust the water flow impact and the outer surface friction, and can also simulate the wear conditions at different pulling speeds, to solve the shortcomings of the existing fire hose wear resistance testing equipment.

[0004] For example, the patent with announcement number CN117990547B provides a fire hose wear test device, which includes a test bench, a water tank and a test mechanism. The test mechanism uses a water pump to deliver water to the fire hose. When the water pressure in the fire hose reaches the specified pressure, the driving member drives the first friction sleeve and the second friction sleeve to rotate forward and backward to achieve simultaneous wear test of the inside and outside of the hose. This application can realize the wear test of the fire hose in the length and circumferential direction. Although this solution can adjust the water pressure according to the actual situation, it cannot adjust the clamping force of the hose synchronously while adjusting the water pressure, so it cannot further adjust the friction force of the outer surface of the hose; this solution cannot change the friction coefficient between the test mechanism and the outer surface of the hose, so it cannot further simulate the real friction situation; although this solution can simulate the wear experiment when the hose is pulled out, it cannot simulate the situation where the hose is actively worn by external objects in a static state.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) Wear-resistant device: water is driven into the pressurized chamber of the pressurized device through the water adding device, and the water pressure drives the pressurized plunger to extend outward.

At this time, the push-pull assembly can slide horizontally, and then manually pull the push-pull assembly again, and the U-shaped friction rod and the L-shaped friction rod respectively drive the first friction column and the second friction column to rotate, so as to realize the wear resistance test of the water outlet belt under static conditions.

[0042] Taking the first embodiment as an example, before the water is passed, the U-shaped friction rod 501 and the L-shaped friction rod 502 on the push-pull assembly 5 are manually pulled to the right, and the U-shaped friction rod 501 drives the first friction column 205 to rotate to change the direction of the groove at the lower end of the first friction column 205, and the L-shaped friction rod 502 drives the second friction column 404 to rotate to change the direction of the friction protrusion 403 at the upper end of the second friction column 404, thereby changing the friction coefficient between the first friction column 205, the second friction column 404 and the surface of the water outlet belt 303, and then the water flow is passed, and the water will enter the control water pipe 208 from the inlet of the water adding shell 602, and then enter the hydraulic push rod 206 from the control water pipe 208, so that the liquid The push rod 206 is inserted into the push-pull slide column 503 to realize the locking function of the push-pull component 5; the valve inside the hydraulic push rod 206 is manually closed, so that when water enters from the inlet of the water filling shell 602, it cannot enter the hydraulic push rod 206, so that the hydraulic push rod 206 cannot be extended and inserted into the push-pull slide column 503, and the push-pull component 5 can slide horizontally at this time, and then the push-pull component 5 is manually pulled, and the U-shaped friction rod 501 and the L-shaped friction rod 502 on the push-pull component 5 respectively drive the first friction column 205 and the second friction column 404 to rotate, so that the first friction column 205 and the second friction column 404 rub against the fixed position of the water outlet belt 303 to realize the water outlet belt 303 wear resistance test under static conditions; manually pull out the transformer assembly 603 in the water adding device 6, and the transformer slider 608 on the transformer assembly 603 will gradually open the three inlets and three liquid outlets 601 of the water adding shell 602, so that multiple streams of water enter the water adding shell 602. At this time, more water flows will have a greater impact on the pressurizing plunger 103 in the pressurizing device 1, causing the pressurizing plunger 103 to move a greater distance to the left. At the same time, more water flows will also increase the water pressure in the water outlet belt 303, and then the pressurizing plunger 103 drives the friction assembly 202 on the wear-resistant device 2 to slide downward through the pressurizing connecting rod 101, and the friction bracket 209 on the friction assembly 202 passes The first friction column 205 is driven downward by the wear-resistant bracket 203 and the wear-resistant mounting seat 204. At this time, the first friction column 205 and the second friction column 404 will clamp the water outlet belt 303, thereby realizing the synchronous control of the internal water pressure and the external clamping force of the water outlet belt 303; when the voltage transformer assembly 603 is manually pulled out, the voltage transformer inclined groove 609 at the upper end of the voltage transformer slider 608 drives the inclined head plunger 402 on the friction assembly 4 to slide upward, so that the second friction column 404 at the upper end of the inclined head plunger 402 extends upward, and then the water flow drives the first friction column 205 to press downward, thereby changing the water pressure and further changing the pressure of the second friction column 404 and the first friction column 205 on the water outlet belt 303;During the descent of the friction clamping bracket 209 on the friction clamping assembly 202, the inner cylindrical surface of the arc-shaped friction block 210 will contact the periphery of the water outlet belt 303, and then the friction clamping bracket 209 will continue to descend, so that the arc-shaped friction block 210 slides to the upper right on the inclined slide rail 218. At this time, the arc-shaped friction block 210 drives the two clamping frames 212 to retract inward through the friction clamping push rod 215 and the friction clamping connecting rod 213, and the clamping frame 212 drives the arc-shaped brake pad 217 to clamp the side of the water outlet belt 303 through the arc-shaped brake disc 216, so as to realize the friction test of the water outlet belt 303 when winding and unfolding; after the water flow enters the pressurized shell 105, the water flow will enter the winding drum 302 through the winding base 301 of the winding assembly 3, and then enter the water outlet belt 303 from the winding drum 302. ;

[0043] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, the transformer assembly 603 in the water-adding shell 602 is manually driven to slide outward along the axial direction of the hollow sleeve 604, and the transformer slider 608 gradually opens the three inlets and three liquid outlets 601 on the side of the water-adding shell 602, so that multiple streams of water enter the pressurized chamber 106 of the water-adding shell 602 from the pressurized through hole 107. At this time, more water flows will have a greater impact on the pressurized plunger 103 in the pressurized shell 105, causing the pressurized plunger 103 to move a greater distance to the left. At the same time, more water flows will also increase the water pressure in the water outlet belt 303, and then the pressurized plunger 103 drives the clamping friction through the pressurized support 102 and the pressurized connecting rod 101. The friction bracket 209 of the component 202 slides downward on the wear-resistant base 201, and the friction bracket 209 drives the first friction column 205 to press down through the wear-resistant bracket 203 and the wear-resistant mounting seat 204. At this time, the first friction column 205 and the second friction column 404 will apply pressure to the water outlet belt 303, thereby realizing the synchronous control of the internal water pressure and the external clamping force of the water outlet belt 303; while manually pulling out the transformer component 603, the transformer inclined groove 609 at the upper end of the transformer sliding block 608 drives the inclined head plunger 402 to slide upward in the friction sliding seat 401, so that the second friction column 404 at the upper end of the inclined head plunger 402 extends upward, and then the water flow drives the first friction column 404 to extend upward. 205 is pressed downward, thereby changing the water pressure and further changing the pressure of the second friction column 404 and the first friction column 205 on the water outlet belt 303; during the descent of the friction clamping bracket 209, the inner cylindrical surface of the arc-shaped friction block 210 will contact the periphery of the water outlet belt 303, and then the friction clamping bracket 209 continues to descend, so that the arc-shaped friction block 210 slides to the upper right on the inclined slide rail 218 and drives the friction clamping spring 211. At this time, the arc-shaped friction block 210 drives the two clamping frames 212 to retract inward on the friction clamping slide seat 214 through the friction clamping push rod 215 and the friction clamping connecting rod 213, and the clamping frame 212 drives the arc-shaped brake pad 216 through the arc-shaped brake disc 216. 17 clamps the side of the water outlet belt 303, at which time the inert gas between the arc brake disc 216 and the arc brake pad 217 will be compressed, and the generated reaction force will further generate pressure on the side of the water outlet belt 303 to achieve the friction test when the water outlet belt 303 is rolled up and unrolled; after the water flows into the pressurized shell 105, the water flows into the winding drum 302 through the winding base 301 of the winding assembly 3, and then enters the water outlet belt 303 from the winding drum 302 to achieve the water supply function; when the water enters the inlet on the side of the water supply shell 602, the water enters the hydraulic push rod 206 on the wear-resistant slide rail 207 through the control water pipe 208;Before manually pulling the transformer assembly 603 outward, it is necessary to first rotate the transformer handle 614 on the transformer seat 611. The transformer handle 614 drives the locking link 607 to move horizontally to the right through the relative sliding of the transformer slide bar 612 in the locking track 606. Because the two ends of the locking link 607 are hinged on the locking turntables 615 of the two locking assemblies 605, and the locking turntables 615 can only rotate, when the locking link 607 moves horizontally to the right, the locking turntable 615 will rotate clockwise and drive the locking link 607 to the lower right as a whole. The locking rotating disk 615 drives the locking rotating shaft 616 to rotate clockwise, and the locking rotating shaft 616 drives the flexible protrusion 617 to rotate clockwise, and the hollow sleeve 604 presses the flexible protrusion 617 back into the locking rotating shaft 616 to realize the unlocking function of the transformer assembly 603; the magnet 613 on the transformer seat 611 is used for magnetic fixation of the transformer handle 614; the inner cylindrical surface of the transformer hole 610 is in friction contact with the outer cylindrical surface of the hollow sleeve 604; the pressure spring 104 is used to limit the distance that the pressure plunger 103 pops out to the left. ;

[0044] like Figure 7 As shown, before water is passed, the U-shaped friction rod 501 and the L-shaped friction rod 502 on the push-pull assembly 5 are manually pulled to the right, and the U-shaped friction rod 501 drives the first friction column 205 to rotate to change the direction of the groove at the lower end of the first friction column 205, and the L-shaped friction rod 502 drives the second friction column 404 to rotate to change the direction of the friction protrusion 403 at the upper end of the second friction column 404, thereby changing the friction coefficient between the first friction column 205, the second friction column 404 and the surface of the water outlet belt 303, and then the water flow is passed, and the water will enter the control water pipe 208 from the inlet of the water adding shell 602, and then enter the hydraulic push rod 206 from the control water pipe 208, so that the hydraulic push rod 206 is inserted into the push rod 206. The sliding column 503 is pulled inside to realize the locking function of the push-pull component 5; the valve inside the hydraulic push rod 206 is manually closed, so that when water enters from the inlet of the water adding shell 602, it cannot enter the hydraulic push rod 206, so that the hydraulic push rod 206 cannot be extended and inserted into the push-pull sliding column 503. At this time, the push-pull component 5 can slide horizontally, and then the push-pull component 5 is manually pulled. The U-shaped friction rod 501 and the L-shaped friction rod 502 on the push-pull component 5 respectively drive the first friction column 205 and the second friction column 404 to rotate, so that the first friction column 205 and the second friction column 404 rub the fixed position of the water outlet belt 303 to realize the wear resistance test of the water outlet belt 303 under static conditions.
